DESCRIPTION
REFILL CONTAINER
TECHNICAL FIELD
[0001]
The present invention relates to a refill container which accommodates toiletries
such as a liquid detergent and fabric softener and food and the like such as cooking oil and
instant coffee.
10 Priority is claimed on Japanese Patent Application No. 2012-221167, filed
October 3, 2012, the contents of which is incorporated herein by reference.
BACKGROUND ART
[0002]
15 Toiletries such as a liquid detergent and fabric softener and food and the like such
as cooking oil and instant coffee are accommodated in a container therefor having a shape
which is easy to use. Having a structure specific to features and uses of the contents, the
container therefor is expensive. Therefore, when the content is empty, the content which
is accommodated in a refill container is sold as a product in order to be able to use the
20 container therefor repeatedly.
[0003]
For example, regarding a container of the liquid detergent, the detergent has to be
taken out by weighing the appropriate amount each time when using it. Therefore, in
order to easily pour the detergent into a measuring cup, a rigid plastic container having a
25 nozzle at a pouring opening portion is used as a repetitive-use container. As a refill
container for the repetitive-use container, to replenish the contents, a container in which a
pouring opening is formed in a flexible container made of a flexible packaging film, or a
container in which a plug is attached to the flexible container is generally used.
[0004]
1
Since the rigid repetitive-use container is designed to pour out easily, the
repetitive-use container is not necessarily suitable for a refill operation to replenish the
contents from the refill container to the repetitive-use container.
[0005]
5 On the other hand, the refill container is also not necessarily suitable for a refill
operation since a focus of manufacturing the refill container is to reduce the cost.
[0006]
A refill container is proposed that can be opened using a nozzle provided in the
repetitive-use container. In addition, a refill container is proposed that does not need to be
10 manually held since the refill container is self-supporting during the refill operation. Such
refill container without manual support includes a coupling member coupled to an opening
portion of the repetitive-use container attachably and detachably and non-removably, and a
container sealing member sealing the refill container body (see Patent Document 1).
[0007]
15 In a refill container described in Patent Document 1, since two members which
are a connect member and a container sealing member are used at a plug portion in order
to connect a repetitive-use container and a refill container, the cost of the refill container
increases. The structure described in Patent Document 1 is screwing the refill container
into an opening portion of the repetitive-use container; therefore, the two members are
20 reliably connected. On the other hand, however, there are drawbacks such that the
handling is bothering and also the cost increases since the plug is provided.
[0008]
In view of the cost, a packaging bag in which the periphery of two packaging
films forming a front and a rear as shown in Fig. 8 is sealed is advantageous. Such refill
25 packaging bag may be provided with a pouring opening portion having an arbitrary width
which is commensurate with a diameter of the container. However, when forming the
pouring opening portion by sealing the periphery portion of the two films forming a front
and a rear, when pouring the content, the opening portion is pulled by the sealed ends.
Therefore, the front and the rear films are in a pseudo-contact state, thereby the pouring
2
opening is clogged or the pouring opening portion is bent easily, and the pouring opening
portion is removed from the repetitive-use container during the refill operation.
[0009]
In order to solve the problems such as the pouring opening is clogged or the
5 pouring opening portion is bent, a lot of packaging bags are proposed such as inserting a
part of a member which is different from a film into the pouring opening portion (see
Patent Document 2), and securing an opening area by expanding a film at the vicinity of
the pouring openmg portion to make a three-dimensional shape (see Patent Document 3).
[0010]
10 However, these packaging bags need processes such as attaching another member
and performing a deep emboss processing. In addition, during the refill operation, it is not
possible to align and stack the packaging bags orderly in the supply portion of the
packaging bags. Furthermore, in the pouring openmg portion where the two films forming
the front and the rear are sealed, since seal portions are formed at both ends, an opening
IS width is narrowed by the amount of the sealing portion, and a sufficient opening cannot be
secured. If the sufficient opening cannot be secured, the time required to dispense the
refill is longer.
[0011]
In order to solve the problems described above, a packaging bag in which a film
20 constituting the packaging bag is bent to form one side of the pouring opening portion and
a sealing portion of the pouring opening portion is formed only at one side is proposed
(see Patent Documents 4 and 5).
[0012]
When the packaging bag has a film in which one side of the pouring opening
25 portion is folded as disclosed in Patent Documents 4 and 5, the issues of closing of the
pouring opening portion and a small opening area of the pouring opening portion are
eliminated. However, as can be seen in the pouring opemng portion of the flexible
packaging bag as shown in Patent Document 5, when the pouring opening portion is set to
be oblique in consideration of the ease of pouring operation, the opening operability
3
becomes unstable.
[0013]
Fig. 9A is a diagram showing a flexible packaging bag described in Patent
Document 5, and Fig. 9B is an enlarged diagram showing a portion of a pouring opening
5 thereof. Such flexible packaging bag includes at the pouring opening portion, a cut line a,
a V-shaped notch b, and a wound processing c with a halftone dot shape provided so as to
cover the cut line a. However, if the position of the V-shaped notch shifts, a tear of the
packaging bag deviates from the cut line a, and it cannot be opened at the original position
of the cut line a.
10 [0014]
In Patent Document 6, as shown in Fig. 10, an opening line to provide a pouring
opening is formed so as to incline with respect to the bend portion. On the opening line,
an easily cutting processing forming a plurality of parallel wound lines is performed.
Moreover, by bending the tip portion of the opening cutting line toward a direction parallel
15 to the opening line, a refill container in which the opening operation of the pouring
opening portion can be performed easily and reliably is proposed.
[0015]
However, since the above-described refill container is rubbed or a hole is made
by rubbing, having shock or the like are provided to the plurality of wound lines formed at
20 the bend portion, a leakage may occur.

a ridge line of the bend portion.
[0019]
According to the refill container of the first aspect, in the bend portion, since a
5 broken portion is provided in the half-cutting lines, it is possible to prevent liquid leakage
caused by the rubbing or tearing of the bend portion.
[0020]
In the second aspect of the present invention, in the refill container according to
the first aspect, more than or equal to a half of the plurality of half-cutting lines is broken
10 at a ridge line of the bend portion.
In the third aspect of the present invention, in the refill container according to the
second aspect, in the plurality of half-cutting lines, the broken half-cutting lines and the
non-broken half-cutting lines are arranged alternatively,
In the fourth aspect of the present invention, there is provided a refill container
15 includingonesheet of lamination body comprising a base material and a sealant layer, and
a pouring nozzle seal portion, where the lamination body is folded such that the sealant
layer is arranged inward to form a bend portion, a surface lamination body, and a rear
surface lamination body, a peripheral portion of the surface lamination body and the rear
surface lamination body is sealed, the bend portion together with the surface lamination
20 body, the rear surface lamination body, and the pouring nozzle seal portion forms a
pouring nozzle which pours a content, a tip of the pouring nozzle is sealed by a pouringnozzle
tip seal portion, the pouring-nozzle tip seal portion is detached along an opening
line to form a pouring opening, on me opening line, an easily cutting processing which
forms one half-cutting line parallel to the opening line is performed, and the half-cutting
25 line is broken at a ridge line of the bend portion.
[0021]
In the fifth aspect of the present invention, in the refill container according to any
one of the first to the fourth aspects, the half-cutting line or the half-cutting lines are
broken when a distance from the ridge line of the bend portion is in a range of 1.0 mm or

more and 4.0 mm or less.
In the sixth aspect of the present invention, in the refill container according to any
one of the first to the fifth aspects, the refill container has a shape of a standing pouch
including, a bottom tape which is formed by further folding such that the sealant layer is
5 arranged outward, and a seal portion which comprises the bottom tape between the surface
lamination body and the rear surface lamination body, and is sealed at a peripheral portion.
[0022]
In the seventh aspect of the present invention, the refill container according to
any one of the first to the sixth aspects further includes a filling opening portion which is
10 formed by opening up a portion of the bend portion and is filled with a content.
EFFECTS OF THE INVENTION
[0023]
According to the aspects of the present invention described above, the refill
15 container is formed such that at least one sheet of lamination body including a base
material and a sealant layer is folded such that the sealant layer is arranged inward to form
a bend portion, a surface lamination body, and a rear surface lamination body, and a
peripheral portion of the surface lamination body and the rear surface lamination body is
sealed. Therefore, unlike the container or the like using a plastic bottle or a plug made of
20 plastic, since the refill container can be manufactured by using only a lamination body for
the soft packaging, the cost of manufacturing the refill container can be reduced.
[0024]
According to the aspects of the present invention described above, one sheet of
the lamination body is folded such that the sealant layer is arranged inward to form a bend
25 portion, and the bend portion together with the surface lamination body, the rear surface
lamination body, and the pouring nozzle seal portion forms a pouring nozzle which pours
a content. Therefore, a pouring opening portion with large area can be secured. As a
result, the refill operation can be performed smoothly and quickly. In addition, the
pouring opening portion can be formed easily and reliably.
7
[0025]
On the opening line and at a peripheral portion of the opening line, an easily
cutting processing which forms a plurality of half-cutting lines parallel to the opening line
is performed. One half-cutting line or a plurality of half-cutting lines is broken when a
5 distance from the ridge line of the bend portion is in a range of 1.0 mm or more and 4.0
mm or less. Therefore, at the bend portion, the half-cutting lines are broken or density of
the half-cutting lines is decreased. Therefore, at the bend portion, it is possible to prevent
the lamination body from rubbing or tearing that causes liquid leakage. In addition, when
the opening tab is lifted, a split of the lamination body increases along the opening line,
10 and a pouring opening can be easily formed at a predetermined position.
[0026]
According to the aspects of the present invention described above, in the plurality
of half-cutting lines, when the broken half-cutting lines and the non-broken half-cutting
lines are arranged alternatively at the vicinity of the bend portion, the density of die half-
15 cutting lines decreases uniformly. Therefore, it is possible to prevent the liquid leakage
and to form an easily cutting of the pouring opening portion easily.
[0027]
According to the aspects of the present invention described above, the refill
container has a shape of a standing pouch including a bottom tape which is formed by
20 folding one sheet of lamination body including the base material and die sealant layer such
Uiat the sealant layer is arranged outward, and a structure of sealing a peripheral portion by
inserting the bottom tape between the surface lamination body and the rear surface
lamination body. Therefore, a refill container having a large capacity and being selfstanding
can be formed.
25 [0028]
According to the aspects of the present invention described above, a filling
opening portion for filling contents is formed by opening up a portion of die bend portion.
In this case, even if a container has a shape in which another seal portion cannot be used
as a filling opening portion, a stable filling operation can be performed.
8
[0029]
According to the aspects of the present invention described above, when a nozzle
of a repetitive-use container including a nozzle cap is inserted to a pouring nozzle, after
the nozzle of the repetitive-use container is inserted to a pouring nozzle which is kept
5 horizontally, the container is inclined such that the pouring nozzle is perpendicular.
Therefore, the refill operation can be performed quickly. In other words, in the refill
container, since the pouring opening portion opens naturally by the bending portion
formed by folding one sheet of the lamination body, it is easy to insert the nozzle in the
desired container. In addition, by designing the size of the pouring opening to fit into the
10 nozzle, it is possible to form the pouring opening that matches the nozzle. Therefore, it is
possible to perform the refill operation quickly by inclining the pouring nozzle to be
perpendicular after inserting the nozzle of the repetitive-use container to the pouring
nozzle held horizontally.

10 EMBODIMENTS FOR CARRYING OUT THE INVENTION
[0031]
Hereinbelow, a refill container according to the present invention is described in
detail with reference to the drawings.
Fig. 1 is a schematic diagram showing a refill container according to one
15 exemplary embodiment of the present invention. Fig. 2 is a schematic diagram of an X-XJ
cross-section of Fig. 1 showing a layer structure ofa lamination body which configures
the refill container. Fig. 3 is an enlarged diagram showing a detail of a pouring nozzle
portion of Fig. 1, and Fig. 4 is a schematic diagram showing a state where a folded portion
of Fig. 3 is unfolded.
20 [0032]
A refill container 1 includes, as shown in Fig. 2, a lamination body having at least
a base material 11 and a sealant layer 12. As shown in Fig. 1, in the refill container 1, a
sheet of lamination body is folded such that the sealant layer 12 is arranged inward to
form a bend portion 6, and a surface lamination body 2 and a rear surface lamination body
25 3 of a main body, and a peripheral portion of the surface lamination body 2 and the rear
surface lamination body 3 is sealed.
[0033]
The bend portion 6 together with the surface lamination body 2, the rear surface
lamination body 3, and the pouring nozzle seal portion 24 forms a pouring nozzle 32
10
which pours the content. A tip of the pouring nozzle 32 is sealed by the pouring-nozzle tip
seal portion 25. When the pouring-nozzle tip seal portion 25 is detached along an opening
line 36, a pouring opening 31 is provided.
[0034]
5 The opening line 36 is a single virtual line starting from an opening cutting line
35, passing through the surface lamination body 2, the bend portion 6, and the rear surface
lamination body 3, and returning to the opening cutting line.
[0035]
In the present exemplary embodiment, at the lower portion of the pouring-nozzle
10 tip seal portion 25, an opening tab 34 divided by the opening cutting line 35 provided at
the pouring nozzle seal portion 24 is formed. By splitting the pouring-nozzle tip seal
portion 25 along the opening line 36 with holding the opening tab 34, the pouring opening
31 is provided (the detail thereof is not shown).
[0036]
15 The opening line 36 is formed so as to incline with respect to the bend portion 6,
and on the opening line and at a peripheral portion thereof, an easily cutting processing 33
which forms a plurality of half-cutting lines parallel to the opening line 36 is performed.
A tip portion 35a of the opening cutting line 35 is bent toward a direction parallel to the
opening line 36. In addition, the half-cutting lines are broken at the bend portion 6.
20 [0037]
The refill container 1 according to one exemplary embodiment of the present
invention, on the opening line 36 and at a peripheral portion thereof, an easily cutting
processing 33 which forms a plurality of half-cutting lines parallel to the opening line 36
is performed. More than half of the half-cutting lines are broken when a distance d from
25 the ridge line of the bend portion 6 is in a range of 1.0 mm or more and 4.0 mm or less.
[0038]
Here, five half-cutting lines are formed from the surface lamination body 2 to the
rear surface lamination body 3, and three of the half-cutting lines are broken over the
distance d from the ridge line {a dashed line shown in Fig. 4) of the bend portion 6. The
11
rest of two half-cutting lines are connected at die ridge line of die bend portion.
[0039]
In addition, the broken half-cutting lines and the non-broken half-cutting lines are
arranged alternatively. Therefore, density of the half-cutting lines at the bend portion 6 is
5 decreased to a half or less of the original density. As a result, it is possible to prevent the
bend portion 6, which is a top portion of the refill container 1, from rubbing or tearing that
causes liquid leakage due to any causes occurred during transporting or handling the refill
container 1.
[0040]
10 Regarding the distance d from the ridge line of the bend portion 6 to a location
where the half-cutting line is broken, if the distance d is too short, rubbing or tearing
resistance is decreased, and if the distance d is too long, opening becomes difficult.
Therefore, it is experimentally suitable Uiat the distance d is in a range of 1.0 mm or more
and 4.0 mm or less.
15 [0041]
Fig. 5 is an enlarged diagram showing another exemplary embodiment of a
pouring nozzle portion. Fig. 6 is a schematic diagram showing a state where a folded
portion of Fig. 5 is unfolded.
[0042]
20 In the exemplary embodiments shown in Figs. 5 and 6, one half-cutting line is
provided on the opening line 36, and the half-cutting line is broken at a ridge line of the
bend portion 6. As described above, in the refill container 1 according to another
exemplary embodiment of the present invention, an easily cutting processing 33 which
forms one or more half-cutting lines parallel to the opening line 36 is performed. More
25 than half of the half-cutting lines (in this case, one half-cutting line) are broken when a
distance d from the ridge line of the bend portion 6 is in a range of 1.0 mm or more and
4.0 mm or less.
[0043]
Here, the bend portion 6 of the refill container 1 is described in more detail. The
12
bend portion 6 is formed such that a top portion of one sheet of lamination body is folded
such that the sealant layer 12 is arranged inward. The bend portion 6 together with the
surface lamination body 2, the rear surface lamination body 3, and the pouring nozzle seal
portion 24 provided at a lower portion of the bend portion form a content discharge pass
5 reaching the pouring opening 31. By the function of the elasticity of the lamination body
in the bent portion 6, the cross-section of the discharge pass always has a swelled shape on
the upper portion. Therefore, it is possible to keep a wide cross-sectional area of the
pouring opening 31, and it is possible to discharge a large amount of contents at once.
[0044]
10 In addition, in the exemplary embodiments shown in Figs. 1-4, by splitting the
pouring-nozzle tip seal portion 25 along the opening line 36 with holding the opening tab
34 divided by me opening cutting line 35 provided at the pouring nozzle seal portion 24,
the opening line 31 is formed. The opening line 36 is formed so as to incline with respect
to the bend portion 6, and on the opening line and at a peripheral portion thereof, an easily
15 cutting processing 33 which forms a plurality of half-cutting lines parallel to the opening
line 36 is performed. A tip portion 35a of the opening cutting line 35 is bent toward a
direction parallel to the opening line 36. Therefore, the opening can be performed
smoothly.
[0045]
20 In the exemplary embodiment shown in Fig. 1, the surface lamination body 2 and
the rear surface lamination body 3 are sealed at a side seal portion 22 and a bottom seal
portion 23 to form a bag-shape. In a practical container, although a filling opening portion
for filling die content is necessary, it is not shown in Fig. 1. In the exemplary embodiment
shown in Fig. 1, a filling opening portion can be provided at the bottom seal portion 23 or
25 the side seal portion 22. In addition, as shown in Fig. 7, the filling opening portion 41 can
be formed by opening up a portion of the bend portion 6.
In addition, when the filling opening portion 41 is provided, the pouring nozzle is
inserted to the filling opening portion 41 to fill the contents. In this case, since die filling
opening portion 41 is expanded, there is a case where an end portion of the pouring nozzle
13
side of the filling opening 41 is pulled and stretched. In order to prevent the stretch, it is
preferable to provide a point seal at die end portion of the pouring nozzle side.
[0046]
In the exemplary embodiment shown in Fig. 1, the bend portion 6 is formed
5 horizontally at the upper portion of the refill container 1; however, the bend portion 6 can
be formed vertically at a side surface of the refill container.
[0047]
The opening line 36 is a virtual line showing an opening position; however, in
order to show clearly the opening position, practically, printing descriptions and the like
10 may be performed. In addition, easily cutting processing 33 is a half-cutting line provided
on the outer surface of the surface lamination body 2 and the rear surface lamination body
3.
[0048]
In order to form the half-cutting line, a method of forming the line using a cutter,
15 and a method of forming the line by laser processing are generally used; however, if the
method of forming the line by laser processing is used, it is possible to form a cut line
more uniformly and stably. As a type of a laser, a carbon dioxide laser is preferable.
Regarding an opening line 36, it is not perpendicular to the ridge line of the bent portion.
By forming the opening line 36 to be inclined as shown in Fig. 1, the operability at the
20 time of pouring is improved.
[0049]
As a lamination body used for a refill container of the present exemplary
embodiment, a lamination body generally used for a flexible packaging bag can be
employed. As a base material 11, paper having one or more layers, a metal foil, or a
25 synthetic resin film is appropriate. As an example, polyolefin-based resins such as a lowdensity
polyethylene resin (LDPE), a high density polyethylene resin (HDPE), a linear
low density polyethylene resin (LLDPE), a polypropylene resin (PP), and polyolefinbased
elastomer; a polyester-based resin such as a polyethylene terephthalate resin (PET),
a polybutylene terephthalate resin (PBT), and a polyethylene naphthalate resin (PEN); a
14
cellulosic-based resins such as cellophane and cellulose triacetate (TAC); a synthetic resin
film such as a polymethyl methacrylate (PMMA) resin, an ethyleue-vinyl acetate
copolymer resin (EVA), an ionomer resin, a polybutene-based resin, a polyacrylonitrilebased
resin, a polyamide-based resin, a polystyrene-based resin (PS), a polyvinyl chloride-
5 based resin (PVC), a polyvinylidene-based chloride resin (PVDC), a polycarbonate resin
(PC), a fluorine-based resin, and an urethane-based resin; and paper, a plastic film or the
like are used as a single body or a compounded body In the base member 11, a printing
layer, an adhesive layer and the like are included as needed.
[0050]
10 As the above-described paper, fine quality paper, one-side art paper, coated paper,
cast-coated paper, Japanese vellum or the like can be used. When paper is used for die
lamination body, die paper may have fractures due to the deep embossing. Therefore,
when paper is used for the refill container according to the present exemplary
embodiment, as a convex emboss and a concave emboss, by forming streaky embosses,
15 the lamination body using paper can be stably used. Moreover, in terms of environmental
considerations, the use of paper is preferable.
[0051]
As the sealant layer 12, a polyolefm-based resin is generally used. In particular,
an ethylene-based resin such as a low density polyethylene resin, a medium density
20 polyethylene resin, a linear low-density polyethylene resin, ethylene-vinyl acetate
copolymer, and ethylene a-olefin copolymer, and a polypropylene-based resin such as a
homopolypropylene resin, propylene-ethylene random copolymer, propylene-ethylene
block copolymer, and propylene a-olefin copolymer are used. Moreover, a multi-layer
composite film of these resins can be used.
25 [0052]
An example of a specific lamination structure is a film laminated such as in the
order of: PET/print layer/adhesive layer/oriented polyamide resin film {hereinafter,
abbreviated as ONY)/adhesive layer/LLDPE; ONY/adhesive layer/LLDPE;
ONY/adhesive layer/ONY/adhesive layer/LLDPE, paper/LDPE/aluminum foil/LDPE; and
15
paper/LDPE.
[0053]
Fig. 7 is a schematic diagram showing a refill container 1 of another exemplary
embodiment.
5 In the refill container 1 of the present exemplary embodiment, a standing pouch
shape is formed such that the sheet of lamination body having at least a base material and
a sealant layer is folded such that the sealant layer is arranged outward to form the bottom
tape 4, the bottom tape 4 is inserted between the surface lamination body 2 and the rear
surface lamination body 3, and me periphery thereof is sealed. In such a shape, since a
10 filling opening portion with which die content is filled cannot be provided at the side seal
portion, a portion of the bend portion 6 is opened up to form the filling opening portion
41. As described above, when an opening portion for filling is provided at a top portion of
the container, the operation of filling the contents becomes easy.
[0054]
15 Since a bottom tape 4 spreads in a container having a shape of a standing pouch,
the container has a large capacity. Therefore, the pouring time using the refill container
can be further decreased.
[0055]
The bend portion 6 is formed such that a top portion of one sheet of lamination
20 body is folded such that the sealant layer is arranged inward. The bend portion 6 together
with the surface lamination body 2, the rear surface lamination body 3, and the pouring
nozzle seal portion 24 form a content discharge pass reaching the pouring opening 31. As
a result, particularly when the content is liquid, since the content smoothly flows through
the linear discharge pass when pouring the content, it is possible to quickly pour the
25 content out. The above-described configuration is more preferable in the present
exemplary embodiment since the container of the present exemplary embodiment has a
large capacity.
[0056]
In order to manufacture the refill container 1 shown in Fig. 7, in the lamination
16
body, which is slit to have a width approximately two times longer than a width
corresponding to a height of of the container, a top portion is folded such that the sealant
layer surface is arranged inward and folded portions face each other to form the surface
lamination body 2 and the rear surface lamination body 3. The surface lamination body 2
5 and the rear surface lamination body 3 are continuously provided, and the bottom tape 4
which is double-folded such that a surface of the sealant layer is arranged outward is

10 As described above, in the refill container according to the present exemplary
embodiment, the pouring opening portion having a large area can be secured without using
a particular plug and the like made of plastic. In addition, since a size of the pouring
opening portion can be designed freely in accordance with a desired shape of the plug in
the repeated-use containers, the refdl container is useful as a dedicated refill container in
15 which a refill operation can be performed quickly.
Hereinbelow, based on the examples, the refill container according to the present
exemplary embodiment is described in more detail.
EXAMPLES
20 [0058]
•^Configuration of Surface Lamination Body and Rear Surface Lamination Body>
As the surface lamination body and the rear surface lamination body, a lamination
body having a configuration described below was used:
PET (P60 manufactured by Toray Industries, Inc., 12um)/print layer/adhesive
25 layer (TM 272 manufactured by Toyo-Morton, Ltd., 3 g/m2(dry))/ONY (ONMB
manufactured by Unitika Ltd., 15 um)/adhesive layer (same as described above)/L-LDPE
(T.U.X® FC-S manufactured by Mitsui Chemicals Tohcello, Inc., 150um).
Configuration of Bottom Tape>
As the bottom tape, a lamination body having a configuration described below
17
was used:
ONY (ONM manufactured by Unitika Ltd., 25 um)/L-LDPE (same as described
above, 120 urn).
[0059]
5 With the lamination bodies described above, a standing pouch having a shape
shown in Fig. 7 was manufactured. The size of a pouch was a width of 130 mm, height of
260 mm, and a bottom folding length of 35 mm. A width of the opening portion is
approximately 18 mm.
A portion of the bend portion is cut to form a filling opening portion. In addition,
10 on the opening line which forms a pouring opening portion of the pouring-nozzle tip
portion, an easily cutting processing which forms a plurality of half-cutting lines by a laser
processing as shown in Figs. 3 and 4 is performed. The distance d was 2 mm. At the
pouring nozzle seal portion, an opening cutting line is formed, and the tip portion of the
opening cutting line is bent toward a direction parallel to the opening line.
15 When opening characteristics of the refill container obtained as described above
were studied, it was possible to open in line with the opening line with a probability of
100%, and the pouring opening portion was stably formed. In addition, a transportation
test was performed such that 10 packaging bodies after the filling were packed in a
cardboard, and no liquid leakage due to rubbing, tearing or the like was occurred.
