The present invention relates generally to collapsible containers and in
particular, but not exclusively, to collapsible male urine bottles.
Urine bottles are frequently used in, for example, hospitals and nursing
homes for patients who are either confined to bed or who are otherwise unabie to
use a toilet. Disposable urine bottles a e k own, which can be discarded after use,
thus eliminating the requirement to empty, ean and sterilise a traditional, nondisposable
urine bottle,
However, in spite of these advantages, a disposable urine bottle typically
takes up the same amount of storage space as a non-disposable urine bottle. t
will be appreciated that a greater number of disposable urine bottles will ne d to
be stored, since they are single-use only. This greater number vastly increases
storage space required, which can be problematic in hospitals and similar
environments, in which storage space is limited.
n view of this, collapsible urine bottles have been developed, such as that
disclosed in US 3,099,017. The urine bottle comprises scorings which allow it to
be folded up to its erected or collapsed configurations. The urine bottle also
comprises a handle which acts to hold the urine bottle in its erected configuration,
However, there are several problems associated with this device. Namely, the
nature of the scoring s particularly complicated which is likely to increase
manufacturing costs, but perhaps more significantly, results in a multi-stage
assembly process, in order to erect the bottle. It will b appreciated that this
laborious set up process is impractical in a busy medical environment,
A further known arrangement is disclosed i US 3,579,653. However,
aside fro also being quite a complicated arrangement of score lines, the nature
of the folding mechanism, for example the inward and upward folding of the bottom
wa l along a median fold line, is unlikely to give a user confidence that the bottle
will resist folding during use.
The present invention has been designed with the foregoing n mind.
In accordance with the present invention, there is provided a container
formed from sheet material, the container comprising an enclosing wall and an
aperture and being expandable from a first, collapsed configuration into a second,
expanded configuration, the sheet material having a plurality of fold lines which
define one or more recesses in the enclosing wall of the container in the expanded
configuration, wherein in the collapsed condition the container comprises a lower
sheet and an upper sheet overlying the lower sheet, the upper and lower sheets
being sealed together along their lateral edges and along a first, end edge
extending between a first end of each of the lateral edges, the lateral edges
tapering towards each other and the aperture extending between the second,
opposite ends of the lateral edges,
The container in accordance with the present invention ca be stood in a
substantially flat configuration, which greatly reduces the volume required for
storage. When required for use, a collapsed container can be transformed into an
expanded urinal. The or each recess in the enclosing wail of the container
facilitates manipulation, lifting and carrying of the container and also helps to retain
the container in its expanded configuration.
Preferably, the upper sheet and lower sheet are of substantially the same
shape and dimensions,
n one embodiment, when the container is in the first, collapsed condition,
each of the upper and lower sheets is substantially planar and comprises a front
edge, two side edges and a rear edge, the front edge Joining one end of each of
the s de edges and the rear edge joining the other end of the side edges.
Preferably, the side edges and rear edges of the upper and lower sheets
are joined to each other. Preferably, the front edges of the upper and lower sheets
are not Joined to each other.
The rear edge may be arcuate, for example part-circular.
Preferably, the side edges of the planar sheets extend along the recesses.
Preferably, the lower sheet comprises a plurality of fold Sines which form a
base wail when the container is n the second, expanded configuration.
Preferably, the container comprises one or more arcuate fold lines which
define a recess in th enclosing wall of the container in the expanded configuration,
The plurality of fold lines in the sheet material may define one or more
elongate recesses in the enclosing wall of the container in the expanded
configuration.
Preferably, the container is formed from a foldabie sheet, for example
foldabie paper pulp card, including paperboard, paper or the like. Preferably the
sheet is liquid resistant. For example, the pulp from which the sheet is made may
comprise a water-resistant composition, such as the fluorocarbon compound
disclosed n GB2439947. Alternatively, o in addition, the sheet may be provided
with one or more liquid-resistant layers or coatings, for example of the fluorocarbon
compound disclosed in GB2439947, or some other liquid-resistant layer or coating.
The container may be formed fro a single, foldabie blank.
Preferably, the material from which the container is made is maceratable,
In a preferred embodiment, the container comprises a urinal,
The present invention also provides a container formed from sheet
material, the container comprising an enclosing wall and an aperture and being
expandable from a first, collapsed configuration into a second, expanded
configuration, the sheet material having a plurality of fold lines which define one or
more recesses in the enclosing wall of the container in the expanded configuration.
n one embodiment, in th first, collapsed configuration the container
comprises an upper sheet and a lower sheet overlying one another and Joined to
one another along a plurality of edges.
Preferably, the upper sheet and lower sheet are Joined to one another
continuously around their periphery except for a portion of the periphery which is
configured to form the aperture of the container in its expanded configuration.
In o e embodiment, the side walls of the upper and lower sheets converge
towards the front edge.

A first embodiment of male urinal is shown n Figs. 1 to 7. The urinai 1 is
formed from a sheet of card formed from paper pulp, out of which is stamped the
blank 12 shown in Fig, 7. The blank 12 is folded and glued to for into the
collapsed urina shown in Figs. 5 and 8 which may be expanded when required to
form the expanded urinal shown in Figs. 1 to 4, in which condition it is ready to
use. The materials from which the urinal is constructed are such that the bottle is
maceratable, .e. it may be disposed of in a conventional macerator in which one
or more impellers reduce the urinal to particles which are sufficiently small that they
can be disposed of in conventional drains and sewers without significantly
increasing the likelihood of blockages. The card from which the urinal 10 is
constructed is also treated to make it impervious to urine for a predetermined
period, typically a few hours, as for prior art urinals. For example, the pulp from
which the card is made may comprise the tluorocarbon compound disclosed n
GB2439947, or some other liquid-resistant additive. Alternatively, or in addition,
the card may be provided with one or more liquid-resistant layers or coatings, for
example of the fluorocarbon compound disclosed in GB2439947, or some other
liquid-resistant layer or coating,
As best seen in Fig. 7, the blank comprises a central panel C having a
short straight front edge 14, two straight s de edges 1 18 in the form of fold lines,
which converge towards, and join, a respective end of the front edge 14, and a
part-circular rear edge 20 which connects the other ends of the s de edges 16, 18.
Two side panels S, mirror images of each other, extend from a respective one of
the two side sides 16, 8 of the central panel C. Each side panel S comprises a
straight front edge 22, a straight outer edge 24, 28 and a rounded, part-circular
rear edge 28. The part-circular rear edge 28 is of the same radius as the partcircuiar
rear edge 20 of the central panel C and the side panels S are slightly wider
than the width of the central panel C. Consequently, when the side panels S are
folded i towards each other aiong the respective edges 1 , 18 of the central panel
C, they lie fiat on the surface of the central panel and the edges of the side panels
S overlap each other, as do the peripheries of the part-circular rear edges 20 of
the central panel C and of the side panels S.
The overlapping portions are secured together by application of a layer of
liquid-resistant PVOH adhesive 30 (although other suitable Siquid-resisfant
adhes es may be used), to form e collapsed urinal shown in Figs. 5 and 6,
having a straight front edge 32, two straight side edges 34, 36 which converge
towards, and join with, a respective e d of, the front edge 32, and a rear, partcircular
end edge 38 which interconnects he opposite ends of the side edges 34,
36. The overlapping portions which form the front straight edge 32 are not secured
together, and thereby define a slot 40 which, when the urinai is expanded, will form
an opening of the urinal 10, as wi l be explained,
The fold lines in he lower leaf of the collapsed bottle (see Fig. 8) define a
base wall 42 on the undersurface of the urinai, defined by two straight fold lines
44, 48 each extending from a point 47 near the rear end of a respective side edge
34, 38 to a respective end of a short centrally-disposed fold line 48 extending
parallel to the front straight edge 32 and located approximately half the distance
from the front straight edge 32 to the furthermost point of the curved rear edge 38,
Two further straight fold lines 50, 52 extend from respective ends of the centrally
disposed fold line 48 to a point 54 near the front end of the associated side edges
34, 38.
On the opposite, upper leaf of the collapsed urinal (see Fig. 5), two curved
fold lines 56, 58 are provided, each extending from the point 47 on the respective
side edge 34, 38 where the straight fold lines 44, 48 meet the s de edge 34, 38
adjacent the arcuate end edge 38 to the point 54 on the respective side edge 34,
3 where the straight fold lines 50, 52 on the lower leaf meet the s de edge 34, 38
adjacent the front edge 32.
The urinal 10 is stored in the flat, collapsed condition shown in Figs. 5 and
8, in which condition it occupies very little volume compared w th a conventional,
moulded urinal. When it is desired to use a urinai, a collapsed urinal is transformed
nto an expanded urinal, shown in Figs. 1 to 4, by pressing inwardly on the opposite
straight side edges 34, 38. This causes the urinai to expand into the condition
shown in Figs. 1 o 4. in particular, it will be observed that the curved fold lines 5 ,
58 on the upper face of the collapsed urinal and the straight fold lines 44, 48, 48,
50, 52 on the lower face of the collapsed urinal result in the formation of generally
lenticular, identical concave recesses 80, 62 on either side of the expanded urinal,
with each of the side edges 34, 36 extending down the length of a respective
recess from comer to corner. The configuration of the recesses 60, 2 also makes
it less likely that the expanded urinal will collapse. The recesses 60, 62 and the
angles formed by he folds the expanded configuration cause external loads
applied to the expanded container to tend to force the sides containing these
recesses closer together, resulting in a much greater resistance to collapse, which
would require these sides to move apart in order to achieve the collapsed
configuration.
As shown in Fig. , when the uhna is in the expanded condition, the two
previously abutting leaves of card which for the urinal 10 separate fro each
other along the front edge 32 and the flow 40 opens to form an opening 58 to the
expanded urinaL The urinal can then be used in the same way as prior art urinals
and subsequently disposed of in a macerator. The concave recesses 54, 46 which
also effectively form the side wails of the expanded urinal, also facilitate
manipulation and lifting of the urinal using one hand.
The second embodiment of the invention, shown n Figs. 8 to 4, is ve y
similar to the first embodiment, the main differences are the number, location and
shape of the fold lines, particular, all of the fold lines on the second embodiment
of urinal are straight.
As for the first embodiment, the second embodiment is a male urinal 10
formed from a sheet of cardboard, out of which is stamped the blank shown in
Fig. 14. The bian 2 is folded and glued to form the collapsed urinal shown n
Figs. 12 and 13, which may be expanded when required to form the expanded
urinal 1 0 shown in F gs 8 to 1, in which condition it is ready to use. As for the
first embodiment, the materials from which the urinal is constructed are such that
the bottle is maceratable and the card fro which the urinal is constructed is
also treated to make it impervious to urine for a predetermined period.
As best seen in Fig. the blank 112 comprises a central panel having
a short straight front edge 114 to which a short projecting flap 1 is connected by
means of a fold line , two straight side edges 1 0, 22 which converge towards,
and join, a respective end of the front edge 1 4 and a part-circular rear edge 124
which connects the other end is of the side edges 0, 122. Two side panels S
mirror images of each other, extend from a respective one of the two side edges
120, 2 of the central panel C Each s de panel S' comprises a straight front edge
6, to each of which a short projecting flap 128 is connected by means of a fold
line 130, a straight outer edge 132, 134 and a rounded, part-circular rear edge 138.
The part-circuiar rear edge 138 is the same radius as the part-circular rear edge
124 of the central panel and the side panels S' are slightly wider than the width
of the centra! panel G Consequently, when the side panels S are folded In
towards each other along the respective fold Sines formed by the side edges 120,
1 2 of the central panel , hey lie fiat on the surface of the central panel and the
edges of the side panels S overlap each other, as do the peripheries of the partcircular
rear edges 124, 138 of the central pane! and the side panels S
The overlapping portions are secured together by application of a liquidresistant
PVOH adhesive 138 to for the collapsed urinal shown in Figs. 1 and
13, having a straight front edge 140, two straight side edges 142, 144 which
converge towards, and join with, a respective end of the front edge 140 and the
rear, part-circular end edge 146 which interconnects the opposite ends of the side
edges 142, 144. The overlapping portions which form the front straight edge 0
are not secured together, and thereby define a slot which, when the urinal is
expanded, will form an opening of the urinal, as will be explained. It will also be
observed that the short projecting flaps 6, 8, are folded back over, and glued
to, the outer surface of the urinal adjacent o the ng ued portion which will form
the opening of the urinal,
The fold lines in the upper eaf of the collapsed bottle (see Fig. 13) define
an upper wai 148 on the upper surface of the urinal, defined by two straight fold
lines 150, 52 each extending from a location near the rear end of a respective
side edge 142, 144 to a respective end of a short centrally-disposed fold line 154
extending parallel to the front straight edge 140 and located approximately one
third the distance from the front straight edge to the further most point of the curved
rear edge 146.
Two further fold lines 158, 15 extend from each end of the central fold line
54, the first fold fine extending to a point 60 on the respective side edge 142,
44 approximately one fifth of the length of the side edge from the front straight
edge 140 and the second fold fine extending to a point 162 approximately halfway
along the respective side edge 142, 144, Further fold lines 4, 166 extend from
the midpoint and the furthest end point of the fold lines 150, 152 to the point 162,
It will also b observed that five fold lines 168 extend from the central fold
line 4 to the front straight edge. The fold lines 188 are equally spaced at the
central fold ne 154, but fan outwardly away from the fold line 4
The fold lines in the lower leaf of the collapsed bottle see Fig. 1 ) define a
lower wall 0 on the lower surface of the urinal, defined by two straight fold lines
172, 174 each extending from a location near the rear end of a respective side
edge 142» 144 to a respective end of a short centrally-disposed fold line 54'
extending parallel to the front straight edge 140 and located approximately one
third the distance from the front straight edge to the further most point of the curved
rear edge 148.
Two further fold lines 6, 8 extend from each end of the centra! fo d line
4, the first fold line extending to the point 0 on the respective side edge 142,
144 approximately one fifth of the length of the side edge from the front straight
edge 140 and the second fold fine extending to the point 182 approximately half
way aiong the respective side edge 142, 144. Further fold ines 0, 82 extend
from the midpoint and the furthest end point of the fold fines 172, 174 to the point
2.
As for the first embodiment, the urinal is stored in the flat, coilapsed
condition shown in Figs. 2 and , in which condition t occupies very !i tl volume.
When it is desired to use a urinal, a collapsed urinal is transformed into an
expanded urinai shown in Figs. 8 to 11 by pressing inwardly on the opposite
straight side edges 142, 144. This causes the urinal to expand nto the condition
shown in Figs. 8 to 1. In particular, will be observed that the fold lines on the
upper and lower faces of th coliapsed urinal results in the formation of identical,
generally diamond-shaped concave recesses 184, 186 on either side of the
expanded urinai, with the side edges 142, 4 extending along the length of the
recesses from comer to corner.
When the urinal is in the expanded condition, the two previously abutting
leaves of card which form the urinal separate from each other along the front edge,
forming an opening 190 to the expanded urinal. The urinal can then be used In the
same way as prior art urinals and subsequentfy disposed of in a macerator. The
concave recesses 184, 8 which also effectively form the side walls of expanded
u na , also facilitate manipulation and lifting of the urinai using one hand.
The five fo d lines 188 on the upper leaf of the urinal 1 0 help to form a
more tubular opening or neck portion to the expanded urinal.
The third embodiment of the invention, shown in Figs. 5 to 24 is very
s mi ar to the first and second embodiments, the main differences being the
number, location and shape of the fo d lines.
As for the first and second embodiments, the third embodiment is a male
urina 2 0 formed from a sheet of cardboard out of which s stamped the blank 2
shown in Fig, 22, The blank 212 is folded and glued to form a collapsed u nal,
shown in Figs, 23 and 24, which may be expanded when required to form the
expanded urinal 210 shown in Figs. 5 to 21, in which condition it is ready to use.
As for the first and second embodiments, the materials from which the
urinai is constructed are such that the bottle is maceratable and the ca d from
which the urinal 210 is constructed is also treated to make it impervious to urine
for a predetermined period.
As best seen n Fig. 22, the blank 2 2 comprises a central panel P having
a short straight front edge 2 to which a projecting flap 21 is connected by means
of a fold line 218, wo straight side edges 220, 222 which converge towards, and
join, a respective end of the front edge 214, and a straight rear edge 224 which
connects the other ends of the side edges 220, 222. An elongate flap 225 extends
along the length of the rear edge 224 and is attached thereto by means of a straight
fold line 228.
Two side panels Q1, G2 mirror images of each other (with the exception
of a handle H on side panel Q2 and reinforcing flaps at the upper edges, as will be
explained) extend from a respective one of the two side edges 220 222 of the
centra! panel P. Each side panel Q1, Q2 comprises a straight outer edge 228, a
straight rear edge 230 extending perpendicularly to the outer edge 228 and a front
edge having a first portion 232 extending perpendicularly to the outer edge 228
and a second portion 234 which is an extension of the straight front edge of the
central panel P. Elongate securing panels 236 extend along the rear edge of each
of the side panels Q , Q2 and securing flaps 238, 240 and 242 extend from the
front edge of the portions 234 of he first and second flaps G 1 Q2 and from the
front edge 232 of the side panel Q .
A U-shaped handle portion H also extends outwardly from the outer edge
228 of the side panel Q2.
The side panels G1, Q2 a e dimensioned such that when they are folded
in towards each other along the respective fold lines formed by the side edges 220,
222 of the central panel P they e f at on the surface of the central panel P and
the edges of the side panels Q1,Q2 overlap each other, and the straight rear edges
230 of the side panels Q , Q2 lie immediately above the straight rear edge 224 of
the central panel P, with the securing flaps 238 of the panels Q1„ Q2 overlapping
each other and overlying the flap 225 of the central panel P
The overlapping portions are secured together by application of a liquid
resistant PVOH adhesive to form the collapsed u nal shown in Figs, 23 and 24,
having a straight front edge 250, two straight side edges 252, 254 which converge
towards, and join with, the respective end of the front edge 40 and the rear straight
edge 256 which interconnects the opposite ends of the side edges 252, 254. The
overlapping portions which form the front straight edge 250 are not secured
together and thereby define a slot 280 which, when the urinal is expanded, will
form an opening of the u nal, as will be explained.
The flaps 236 of the side panels Q1, Q2 and the flap 225 of the central
panel P are glued to each other and are also folded back over, and glued to, the
outer surface of the urinal. In addition, the flaps 2 , 238, 240 and 242 at the upper
edge of the urinal are folded back over, and glued to, the inner surface of the urinal
adjacent to the edge in order to reinforce the portion of the blank which will form
the opening O of the urinal.
St w i also be observed that the handle portion is not glued to the rest of
the male urinal but is merely connected to elongate edge 228 of s de panel G2
along connecting folds,
The fold fines in the upper e af of the collapsed bottle define an upper wall
262 on the upper surface of the urinal, defined by two fold li es 264, 266 which are
symmetrical about the longitudinal axis of the collapsed urinal. The fold lines
comprise a curved portion 264a, 286a extending from the lower corners of the
collapsed urinal, which merge into two straight, parallel fold lines 284b, 288b where
they meet the unglued slot portion 280 which will form the opening 0 of the urinal.
Two further curved fold lines 270, 272 extend from the curved portion of
each of the aforementioned fold lines on the upper af, to the respective lateral
edges of the collapsed urinal.
The fold lines ire the lower leaf of the collapsed bottle define a lower,
trapezoidal base wall B defined by two straight fold lines 274, 278 extending from
the lower comers of the collapsed urinal to a respective end of a short centrallydisposed
fold l ne 278 extending parallel to the rear edge 256 and located
approximately halfway between the front and rear edges of the collapsed urinal.
Two further fold lines 280, 282 extend from each end of the central fold line,
almost parallel to each other but diverging slightly, towards the front edge 250 of
the collapsed urinal.
Further straight fold lines 284, 288 extend from the junction of the
aforementioned curved foid lines 270, 272 and the respective lateral edges 252,
254 of the collapsed urinal, These further fold Sines are straight and converge at
the respective ends of the central fold line,
As for the first and second embodiments, the urinal is stored in the flat,
collapsed condition n which it occupies very little volume. When it is desired to
use the urinal, a collapsed urinal is transformed into an expanded u inal shown in
Figs. 15 to 22 by pressing inwardly on the opposite straight side edges. This
causes the urinal to expand into the condition shown in Figs. 5 to 22 a d in
particular forms an elongate tubular neck portion N having the opening O at ts
upper end. In particular, it will be observed that the fold lines on the upper and
lower faces of the collapsed urinal results in the formation of identical, generally
curved recesses R1, R2 on either side of the expanded urinal, with the side edges
extending along the length of the recesses fro corner to corner.
When the urinal is in the expanded condition, the two previously abutting
leaves of card which form the urinal separate fro each other along the front edge,
forming an opening to the expanded urinal, The urinal can then be used in the
same way as prior art urinals and subsequently disposed of in a macerator. The
concave recesses which also effectively form the side walls of the expanded urinal
also facilitate manipulation and lifting of the uri na using one hand.
It will also be observed tha the expanded urinal can be rested on the base
wall before, during and after use. After use, the urinal can be disposed of in a
macerator, as for the previous two embodiments.
The invention is not restricted to the details of the foregoing embodiments.
For example, although the specific description refers to the urinals being made
from paper pulp card, other sheet materials including (but not limited to)
paperboard and paper may be used instead.
Also, other types of adhesive may be used instead of, or in addition to,
PVOH adhesive, Indeed, other methods of securing the edges of the blank to form
the collapsed container may be used, for example heat sealing.
Moreover, although the specific embodiments refer to urinals, the invention
is also applicable to other types of container including (but not limited to) bottles,
for example.
