ORIGINAL
FIELD OF INVENTION
[001] The present disclosure relates to caps, specifically, the present
disclosure relates to a peel-off cap seal fitted on top of a container for sealing
the mouth of the container.
5 BACKGROUND
[002] it is common to use caps to cover/seal the mouth of a container. Various
types of caps are used, for example, snap-fit caps, screw caps, cork stopper, etc.
For containers used to store liquids, for example, liquor, pull-off caps are
preferred. In accordance with a prior art EP 1818272, a tear-off anti-tamper seal
10 fitted to stopper-type closing members mounted on the open end of the neck of
a bottle is disclosed. The seal includes a tubular body that has an annular top
flange and a sleeve portion which extends axially from the said flange along the
neck of the container, means for fixing the said sleeve portion to the neck of the
container to prevent relative axial movements, means for also preventing
15 relative angular movements of said sleeve portion and the neck of the container,
a circumferential weakening line formed on the said sleeve portion, a pair of
weakening lines which extend axially along the said sleeve portion of the
tubular body and are situated in the zone between the said top flange and the
said circumferential weakening line, said axial lines defining on the tubular
20 body two perimetral zones, one of which has a circumferential extension
smaller than that of the other zone, and a tear-off tongue projecting towards the
inside of the said tubular body and fixed to the said top flange in the zone
between the said axial weakening lines which has a smaller circumferential
extension.
25 [003] The problem with the abovementioned prior art is that in order to tear
the seal, a large force has to be applied to the tear-off tongue, which causes
inconvenience to the user and may also break the tongue without peeling the
portion of the tubular body between the two perimetral zones.
[004] Alternatively, the caps in use require a user to rotate the seal in order to
tear off the seal. There is thus a need for a cap that address the above
drawbacks.

DETAILED DESCRIPTION
[017] The particular values and configurations discussed in these non-limiting
10 examples can be varied and are cited merely to illustrate at least one
embodiment and are not intended to limit the scope thereof
[018] The present disclosure provides a peel-off cap seal that is provided on
the neck and mouth of a container such that it seals the mouth of the container.
In an embodiment, the peel-off cap seal includes a body with a base, an upper
15 portion and a top portion. The top portion partially or completely covers the
mouth of a container and includes at least two flaps with intermediate structures
therebetween. The upper portion is coupled to the base on one side and is
adjacent to the top portion on the other side. The upper portion and the base
surround the neck of the container. In an exemplary embodiment, the upper
20 portion includes two or more segments that are coupled to respective flaps.
When a flap is lifted and pulled down, the corresponding segment is peeled off
from the upper portion, thereby loosening the peel-off cap seal from the neck of
the container. In another exemplary embodiment, the upper portion is formed of
a plurality of segments adjacent to each other. Each segment is coupled to a
25 respective flap. When a flap is lifted and pulled down, the corresponding
segment is peeled off from the upper portion, thereby loosening the peel-off cap
seal from the neck of the container.
[019] FIG. 1 is a first perspective view of a peel-off cap seal 100 in
accordance with a first embodiment of the present disclosure. The peel-off cap
seal 100 is mounted on a container such that it surrounds the neck of the
container and covers the mouth 102 of the container. The container may be a
5 bottle, tube, etc. The mouth of the container may be of any shape for example,
circular, square or oval in shape. Accordingly, the shape of the peel-off cap seal
will be circular, square or oval.
[020] The peel-off cap seal 100 includes a base 104, an upper portion 108 and
a top portion 110 that together form the body of the seal 100. In the exemplary
10 depicted embodiment, the shape of the base 104 and the upper portion 108 is
tubular while the top portion 110 is circular. The body may be made of
materials that include without limitation, plastic material such as acrylonitrile
butadiene styrene (ABS), high density poly-ethylene (HOPE), high density
poly-propylene (HDPP), low density poly-ethylene(LDPE), low density poly-
15 propylene(LDPP) and other recyclable plastic material. In addition, non-plastic
material such as aluminium may be used.
[021] The base 104 is segregated from the upper portion 108 via a first semicut
line 106 provided in the body of the seal lOO.The first semi-cut line 106 is a
line that loosely connects the base 104 to the upper portion 108. The first semi-
20 cut line 106 runs radially between the base 102 and the upper portion 108 and
may be in the form of a series of slits. In various embodiments, the first semicut
line 106 may be without limitation, in the form of a ring with zig-zag slits
or straight slits. Further, in the exemplary depicted embodiment, the base 104 is
thinner than the upper portion 108. However, it is possible to vary the width of
25 the base 104 as well as the upper portion 108 based upon the requirement. The
base 104 remains fixed on the bottle and serves to provide tamper resistance,
for example, the base is attached to the bottle in a way that it may not be
removed from the bottle without destroying it or at least causing formation of
irreversible bends, cracks or other evidences of tamper such as formation of
30 tamper marks.
[022] The upper portion 108 is coupled to the top portion 110 on the other
end. In the exemplary embodiment, the top portion 110 is at 90 degrees to the
upper portion 108. However, it is possible to vary the angle between the top
portion 110 and the upper portion 108 based upon the requirement. The upper
5 portion 108 includes a plurality of segments 112 such that each segment 112 is
a zone enclosed between a pair of second semi-cut lines 114, the first semi-cut
line 106 and a flap 116. The second semi-cut lines 114 run axially on the upper
portion 108 while the first semi-cut line 106 is provided radially on the surface
of the seal 100. The second semi-cut lines 114 run between the two ends of the
10 upper portion 108, namely, from the first semi-cut line 106 to the junction of
the upper portion 108 and the top portion 110.
[023] The top portion 110 includes two flaps 116 and two intermediate
structures 118. As shown, between two intermediate structures 118, a flap 116
is provided. Though the intermediate structures 118 are depicted as semi-
15 circular flanges, the intermediate structures 118 can be of other shapes too. The
flaps 116 and the intermediate structures 118 may sit on top of a cap provided
on a container or on the mouth of a container. The flaps 116 are designed such
that one end is connected to a respective segment while the other end is free.
The shape of the flaps 116 can be varied to include without limitation triangle,
20 rectangle, etc. The flaps 116 are preferably arranged in such a way that it is
convenient for a user to insert a finger and pull the flap in order to peel off the
seal. In an embodiment, the intermediate structures also have a notch in them so
that it is convenient for a user to insert his finger and peel off the intermediate
structures in order to access the contents of bottle. In an embodiment, the
25 intermediate structures 118 and flaps 116 may be designed to depict a logo of a
brand. The flaps 116 may be made of a material having elasticity one of same,
more than or less than that of the body of the seal 100. The materials include
without limitation, plastic material such as acrylonitrile butadiene styrene
(ABS), high density poly-ethylene (HDPE), high density poly-propylene
30 (HDPP), low density poly-ethylene(LDPE), low density poly-propylene(LDPP)
and other recyclable plastic material. In addition, non-plastic material such as
aluminium may be used.
[024] The peel-off cap seal 100 may be placed on top of a cap to act as a seal
or may be fitted on the mouth/neck of a container. In the latter case, a cover for
5 example, a circular piece may be provided below the flaps 116 and intermediate
structures 118 to cover the mouth of the container completely.
[025] For sake of simplicity, other attachments provided with the cap like,
means to restrict axial movement, means to restrict radial movement, etc are not
disclosed. It will be appreciated that any such attachment can be used with the
10 seal 100 in line with the teachings of the present invention.
[026] FIG 2 illustrates an exemplary top view of the first embodiment. The
flaps 116 partially cover the mouth 102 of the container. Protrusions 406 appear
between an intermediate structure 118 and a flap 116. The protrusions 406 may
be part of the cover of a container and provided to improve a user's grip while
15 rotating the cover of the container. 'to
[027] FIG 3 illustrates a side view depicting various semi-cut lines present on
the surface of the seal 100. In this side view, the first semi-cut lie 106 runs
radially while the pair of second semi-cut lines 114 are provided in the axial
direction. These lines demonstrate that once the corresponding flap 116 is lifted
20 and pulled down, it will tear from the body along the semi-cut lines 114 and
106. In an embodiment, the semi-cut lines 106 and 114 may not appear on the
surface of the seal 100. In such an embodiment, other mechanism may be
provided such that the material of construction is weakened along the semi cut
lines 106 and 114 so that it is easier to peel off the segment. It should be noted
25 that the number of pair of semi-cut lines 114 correspond to the number of flaps
116. For instance, if two flaps 116 are provided, there will be two pairs of semicut
lines 114, namely, fours semi-cut lines 114.As a variation, in accordance
with the teachings of the present disclosure, the semi-cut lines 114 may not
intersect with the first semi-cut line 106.
[028] FIGS 4 and 5 illustrate the operation of the seal 100. In order to break
the seal, flaps 116 are lifted upwards and then peeled down as depicted by
arrows 402. Due to the semi-cut lines 114 present in the upper portion 108, the
amount of force required to peel the segment 112 is minimal as opposed to
5 peeling of a proper bonded structure. Once the flaps and the corresponding
segments are opened, the adherence of the intermediate structures 118 to the
neck of a container also weakens. The intermediate structures can be peeled
down sideways easily due to this weak bonding as depicted by arrows 404.
[029] The intermediate structures 118 as well as the flaps 116 and segments
10 112 can thereafter be torn apart easily via the first semi-cut line 106. This
would make the base 102 of the seal 100 free and hang around the neck of the
container revealing the container cover which in turn is rotated and unscrewed
to reveal the mouth of the container. In the exemplary depicted embodiment, it
may be seen that a cover 406 is provided below the peel-off cap seal 100.
15 [030] It may be seen that breaking of a seal of a cap using the present
disclosure as opposed to a one-part structure is easy, quick and requires
minimal force.
[031] FIG 6 illustrates an exemplary second embodiment of a peel-off cap
seal 600. Rather than employing two flaps, it depicts three flaps 116 provided
20 in the top portion 110 separated by intermediate structures 118 in between.
Accordingly, the upper portion 108 includes three pairs of second semi-cut
lines 114 running axially on its surface.
[032] It may be noted that various embodiments of the present disclosure are
possible like, providing flaps of unequal sizes, providing a hook or other lifting
25 mechanism with the flaps and/or supporting members, providing differently
shaped flaps, etc. All such variations are within the scope of the present
disclosure.
•
[033] Yet another exemplary embodiment of the present disclosure is depicted
in FIG 7. The top portion 110 may be made of a plurality of flaps 116, for
example, five flaps 116 as shown. In this embodiment, the upper portion 108 is
made of a plurality of segments the number of which correspond to the number
5 of flaps. For example, in the depicted embodiment, given that there are five
flaps 116, the upper portion 108 will be formed of five segments 112. Two
consecutive segments 112 will be separated by a second semi-cut line 114. The
description of the base 104 and first semi-cut line 106 can be referred from FIG
1. Though the flaps 116 are shown to be of same shape and size, it is possible to
10 vary the shape and size of each or some of the flaps 116. Accordingly, the
width of the segments 112 may vary.
[034] In this embodiment, by peeling off flaps 116 one after the other, the
upper portion 108 may be removed from the container.
[035] The above embodiments can be used with a variety of bottles or tubes.
15 For example, in case of small bottles, the peel-off cap seal may be provided
directly on the mouth and neck of the bottle/tube. In another example relating to
bigger bottles, the mouth and neck of the bottle may be covered by a cover on
top of which the peel-off cap seal may be provided. In such cases, to regulate
the flow of ingredients of the bottle, a flow control mechanism may be
20 employed. The flow control mechanism may be any mechanism commonly
known in the art. Such flow control mechanism may be provided in the cover of
the bottle on which the peel-off cap seal is mounted.
[036] It will be appreciated that variations of the above disclosed and other
features and functions, or alternatives thereof, may be desirably combined into
25 many other different systems or applications. Also, that various presently
unforeseen or unanticipated alternatives, modifications, variations or
improvements therein may be subsequently made by those skilled in the art
which are also intended to be encompassed by the following claims.
10
[037] Although embodiments of the current disclosure have been described
comprehensively, in considerable detail to cover the possible aspects, those
skilled in the art would recognize that other versions of the disclosure are also
possible.
