Description

Field of the invention

The present invention relates to a single-use liquid container which is made from sheet material in particular for holding body fluids in a medical environment, and which can be expanded with a simple movement. The present invention further relates to a collapsed single-use container and to a blank. The single-use, expandable container may in particular be used as a urinal or as a sick bag.

Background of the invention

Single-use containers which are made from sheet material have been known for quite some time. Single-use containers may be used as urinals and in that case have an advantage over reusable urinals in that they significantly reduce the risk of Hospital Acquired Infections, because reusable urinals are often not cleaned very well in practice and become a source of infections. This type of infection does not occur with single use urinals.

An example of a single-use, collapsible container is disclosed in GB2529713A. This document discloses a collapsible container, in particular a collapsible male urinal. A disadvantage of this container is that the shape is not very well suited for a human body. The container has a rather angular shape which feels rather inconvenient for a user when the container is placed between the legs of the user. Furthermore the container cannot be expanded (“popped-up”) by a simple movement.

Another example of a single-use liquid container is disclosed in US2016/0262583A1. The containers disclosed in this document are in particular made from carton and are formed from a pre-cut blank.

This container has a similar drawback in that the three-dimensional shape is not well suited to be used as a urinal. The container does not fit very well between the legs of a user when the user is lying in bed. Moreover, the shape of the entry opening is not very suitable for various positions which a user may have when lying in a bed. This holds in particular when the user has a supine position. Furthermore, the container cannot be expanded in full form by a simple movement. Moreover, when the container contains liquid, it tips over quite easily at a typical 10-15° mattress angle and spills the liquid quite easily.

-2The challenge of providing a user friendly and sturdy shape is particularly difficult because single-use containers need to be able to be transformed between a collapsed state and an expanded use state. In the collapsed state, the single-use container should be rather flat in order to save storage space. The background of this requirement is that in a typical medical environment such as a hospital, many of these single-use containers are used on any given day. Therefore, many single-use containers need to be kept in storage, often close to patients. If all these single-use containers would be stored in their expanded use state, a very large storage space would be required. Therefore, it is generally desirable that such single-use containers can be collapsed and stored in a collapsed or nestable form.

At the time of usage, it should further be easy to transform the single-use container from the collapsed state into the expanded and structurally strong use state. This requirement makes the challenge of providing a user friendly form extra challenging.

Object of the invention

It is an object of the present invention to provide a single-use container, in particular for holding body fluids, wherein the single-use container can be stored in a collapsed state and can be expanded to a use state with ease, wherein the single-use container provides increased comfort to a user through ergonomic shape of the container.

Furthermore, it is an object that the expanded container is strong and sturdy enough to be easily handled and fulfil the role of urinal or body fluid container. Providing such relatively high structural strength with an easy to expand container from the flat state is a specific objective of this invention.

It is an object of the present invention to provide a single-use urinal which can be stored in a collapsed state and can be expanded to a use state with ease and which provides increased comfort to a user, in particular when lying in a bed, more in particular when lying in a supine position.

It is an object of the present invention to provide a single-use container for body fluids which can be manufactured with less material than single-use containers of the prior art.

It is an object of the present invention to provide for a single-use container that can be produced from a flat blank at high manufacturing speeds and low production costs.

-3It is an object of the present invention to provide for an easy to expand, single-use container that provides for high structural strength.

It is an object of the present invention to provide a single-use container for body fluids which does not require any oil-based wax water-proofing treatment.

It is an object of the present invention to provide a single-use container which is a suitable alternative for the prior art.

Turning to figures 5, 6 and 7, the left base portion 44 and the right base portion 46 are folded inward. The overlap portions 48 of the right and left base portion are attached to the inner sides 64 of the front and rear base portions 45, 47 by adhesive connections.

A support 68 may be inserted through the upper end when it is still open to support the forming of the base section 13.

- 17Subsequently, the front and rear base portions 45, 47 including the overlap portions 48 and the diagonal fold lines 54, 55, 56, 57 are folded over the outer sides 65 of the right and left base portions 44,46 and attached thereto by adhesive connections.

Together, the left base portion 44, front base portion 45, the right base portion 46 and the rear base portion 47 form the base section.

With reference to figure 6, the base section 13 is then folded onto itself over a central base fold line 66. The result is a collapsed single-use container 100 as shown in figure 7. The collapsed single-use container 100 has an upper flap 102.

Turning to figures 8-11, in an alternative way of making the collapsed single-use container 100 from the blank, the circumferential wall and the base section may be formed in one operation. The adhesive is applied in the same regions, but the left base portion 44, front base portion 45, the right base portion 46 and the rear base portion 47 are folded and attached at the same time as the circumferential wall.

Collapsed single-use container

With reference to figures 7, 11 and 12, the collapsed single-use container 100 is configured to be expanded into a single-use container. The collapsed single-use container 100 comprises a base section 13 folded onto itself along a central base fold line 66. The base section comprises a front base portion 70 and a rear base portion 71.

The collapsed single-use container 100 comprises a front part 72 comprising:

o a central front part 73 which defines the front wall of the single-use container which is to be formed, o a left front part 74, which defines a forward part of the left wall of the singleuse container which is to be formed, o a right front part 75, which defines a forward part of the right wall of the single-use container which is to be formed,

It will be clear to the skilled person that a rear part 76 of the collapsed single-use container 100 is formed in the same way as the front part 72 and comprises o a central rear part which defines the rear wall of the single-use container which is to be formed, o a left rear section which defines a rearward part of the left wall of the singleuse container which is to be formed,

- 18o a right rear section which defines a rearward part of the right wall of the single-use container which is to be formed.

Left and right in this paragraph are defined as left and right when the collapsed singleuse container 100 is seen in front view.

The collapsed single-use container 100 comprises an upper end 69 where the front part and rear part meet. The upper end is formed by the flaps 26, 27 which in the case of a urinal are attached to one another.

The left front part 74 is delimited from the central front part 73 by a left front folding line 80. The right front part 75 is delimited from the central front part 73 by a right front folding line 81. The left and right front folding lines 80, 81 are curved and define a waste section 35 in the central front part 73, the waste section having a smaller width than a lower portion of the central front part 73 and an upper portion of the central front part.

The right front part and the right rear part are formed from the right wall zone 33 of the blank which right wall zone 33 is folded about its fold line 15. The left front part and left rear part are formed from the left wall zone 34 of the blank, wherein the left wall zone is folded about its fold line 14.

Except for the pee opening or pee opening area, the collapsed single-use container may be the same when viewed from the rear as when viewed from the front. For this reason the rear side is not shown separately. Therefore, the left rear part is delimited from the central rear part by a left rear folding line, and the right rear part is delimited from the central rear part by a right rear folding line. The left and right rear folding lines are curved and define a waste section in the central rear part, the waste section having a smaller width than a lower portion of the central rear part and an upper portion of the central rear part.

The collapsed single-use container 100 comprises a right edge 82 and a left edge 83. In front view the right edge 82 comprises an upper right edge 84 and a lower right edge 85, and the left edge 83 comprises an upper left edge 86 and a lower left edge 87. The collapsed single-use container 100 also has a lower base edge 89 and a curved upper edge 90.

Due to the fact that the base section 13 is folded onto itself:

the lower right edge 85 comprises a front lower right edge part 85A and a rear lower right edge part 85B, and

- 19the lower left edge 87 comprises a front lower left edge part 87A and a rear lower left edge part 87B.

The upper right edge 84, the front lower right edge part 85A and the rear lower right edge part 85B form folding lines which can be pushed inwards, thereby forming the concave right wall during the expanding of the collapsible container. The upper left edge 86, the front lower left edge part 87A and the rear lower left edge part 87B form folding lines which can be pushed inwards, thereby forming the concave left wall during the expanding of the collapsible container.

The upper right edge 84 and the lower right edge 85 extend at an angle a of 120-160 degrees relative to one another and define a right side corner 91. The upper left edge 86 and the lower left edge 87 extend at an angle a of 120-160 degrees relative to one another and define a left side corner 92.

In front view the lower right edge 85 and the lower left edge 87 extend at an angle β of 120-160 degrees relative to the lower base edge 89 of the collapsed single-use container 100.

With reference to figures 13A and 13B, the right front part 75 and right rear part together are deformable into the right wall of the single-use container by pushing the right edge 82 of the collapsed single-use container inward, thereby expanding the collapsed single-use container into an expanded state. The left front part 74 and the left rear part together are deformable into the left wall of the single-use container by pushing the left edge 83 of the collapsed single-use container inward.

It is noted that on each side of the base section 13 which is folded onto itself, triangular areas 93, 94 are present which are also folded onto themselves. The triangular areas 93, 94 form part of the diamond sections 7,8 of the blank. When the collapsed singleuse container is expanded, these triangular areas also become part of the right wall respectively left wall. The triangular areas are indicated in figures 6 and 10. Each triangular area 93, 94 is itself composed of two triangular areas..

Expanded single-use container

Turning to figures 14, 15, the single-use container 200 is shown. In the explanation of the various parts of the single-use container 200, fresh reference numerals are used for parts which are only present in the expanded use state. For parts which are also present in the

-20collapsed state or present even in the blank, the same reference numerals are used as for the collapsed container or for the blank.

The single-use container 200 is manufactured from sheet material in particular cardboard. Due to the way the single-use container 200 is folded, there is no need for any oilbased wax water-proofing treatment.

The single-use container 200 comprises a front wall 201, a right wall 202, a left wall 203 and a rear wall 204. The single-use container 200 comprises a base 206. The base is flat and forms a surface on which the single-use container can stand. The base 206 has a square or rectangular shape.

The walls 201,202, 203, 204 which extend upward from the base 206. The front wall 201 and the rear wall 204 are convex. The right wall 202 and left wall 203 are concave. The single-use container 200 comprises an upper end 207 which connects the front wall, right wall, left wall and rear wall.

The single-use container 200 comprises a pee opening area 28 having a perimeter

208 which is at least partially weakened. The perimeter can be broken, resulting in a flap 205 which can be folded outward and a pee opening 209 via which urine may enter the single-use container. The flap may be covered with moisture absorbing material. The fold line where the flap is attached to the front wall is relatively soft, further improving the comfort of the user and preventing paper cuts in delicate body parts.

In another embodiment, the flap may be folded inward. In yet another embodiment, the flap may be torn of completely. In again another embodiment, the flap may not be present and the pee opening already exists in the blank 10.

The pee opening 209 or pee opening area 28 is provided at the level of the waist section.

The single-use container may also comprise a second pee opening or pee opening area in the rear wall. The second pee opening or second pee opening area may have a different size or shape than the first pee opening or pee opening area.

The single-use container comprises a vertical flap 150 at the upper end, wherein the vertical flap comprises in particular a through hole 151.

-21 The single-use container may have a volume below a lower rim of the pee opening 209 of between 0,5 and 1,5 litre.

Turning to figure 17, in front view the single-use container has a waist section 35, the waist section having a front width W1 which is smaller than a front width W2 at the base and smaller than a front width W3 at the upper end (widths are indicated in fig. 1). In particular the front width gradually decreases from the base 206 to the waist section and gradually increases from the waist section to the upper end 207. It is further noted that the very upper part 241 of the right wall 202 and the left wall 203 may be convex or straight instead of concave, but the overall shape of the right wall 202 and the left wall 203 is convex.

Turning to figure 18, in side view the single-use container has a side width W4 which reaches a maximum at the level of the waist section, the side width at the waist section being greater than the side width W5 at the base and greater than the side width W6 at the upper end. The side width in particular gradually increases from the base to the waist section and gradually decreases from the waist section to the upper end.

The front wall 201 and the rear wall 204 meet at the upper end 207. In front view, the upper end is wider than the base but obviously this may be varied. The right wall 202 and the left wall 203 do not meet at the upper end. It is noted that the very upper part 240 of the front wall 201 and the rear wall 204 may be concave or straight instead of convex, but the overall shape of the front wall 201 and the rear wall 204 is convex.

A triangular fold section 350 is visible at the bottom of the right side wall 202 in fig. 18. The triangular fold sections 350 is composed of two smaller triangles on either side of the fold line 15 in the right side wall 202. The triangular fold section 350 results from the diamond shaped folding section 7.

Turning to figures 19A, 19B, 19C, the single-use container 200 comprises a curved front right edge 210 which extends upward from a front right corner 214 of the base, a curved front left edge 211 which extends upward from a front left corner 215 of the base, a curved right rear edge 212 which extends upward from a rear right corner 216 of the base and a curved left rear edge 213 which extends upward from a rear left corner 217 of the base, wherein the curved right front edge 210 and the curved right rear edge 212 meet at the upper end and wherein the curved left front edge 211 and the curved left rear edge 213 meet at the upper end.

-22The curved edges 210, 211, 212, 213 are formed from the fold lines 80, 81, 181, 182 from the blank and from the collapsed container. The side wall fold lines 14,15 remain visible in the single use container and extend over the right and left wall.

The front wall 201, the right wall 202, the left wall 203 and the rear wall 204 are integrally connected to one another via three fold lines 80, 81,181 which form three upstanding edges 210, 211, 212 which extend upwardly from three corners 214, 215, 216 of the base. The adhesive connection is formed at the fourth fold line 182.

Two walls 201,204 are connected to one another via an adhesive connection at a fourth upstanding edge 213 which extends upwardly from a fourth corner 217 of the base. The skilled person will understand that the adhesive connection may be formed at any of the four upstanding edges.

Turning to figures 20A, 20B, 20C a male version is shown, which has a pee opening area 28 which is located slightly higher up, resulting in large volume below the lower rim of the pee opening.

Turning to figures 21,22, 23 and 24 another embodiment of the invention is shown. The embodiment is narrower in the sense that the base 206 is rectangular having a length L1 which is significantly greater than a width W7, The pee opening area 28 or pee opening is located in a right or left wall 202, 203. The base perimeter fold line 30 is straight. This embodiment is specifically useful for female users who are in bed in a supine position. The relatively narrow shape of the single-use container allows easy positioning between the legs.

Turning to figures 25, 26, 27, 28 a single-use container 200 is shown which is configured as a sick bag. The flaps 26, 27 are not connected to one another, but stay loose.

The vertical flap 150 has a wave shape, resulting in a higher portion (left) and a lower portion (right). The higher portion is intended to be positioned at the nose and the lower portion is intended to be positioned at the mouth or chin.

Turning to figures 29, 30 and 31 the upper end can be opened by the user by pushing the left and right corners 221,222 inward. This creates an upper opening 220 and also changes the shape of the single-use container as is shown in figure 30. The user can then vomit into the sick bag. The single-use container 200 does not have a pee opening or pee opening area. This embodiment may also be used as a urinal, for instance in a car. In this

-23case the higher portion of the flap 150 is intended to form is the forward portion and the lower portion is intended to be placed under the bumb.

Use

The method of forming the single-use container from the collapsed container comprises pushing a left edge and a right edge of the collapsed single-use container inward, and forming the concave right and left wall and the convex front and rear wall.

Turning to figures 32A-E, a male or female user 228 can lie on a bed with the back somewhat upright. The legs 230 are separated and the knees slightly lifted. The single-use container 200 can be positioned between the legs 230. The upper end 207 projects upward from between the legs and the user can hold the upper end 207 with his or her hand. The legs may squeeze together, thereby clamping the single-use container as shown in fig. 32D. The user may then pee. When finished, the legs are spread again and the single-use container 200 may be removed and disposed of.

Turning to figures 33, 34 and 35, it is shown that the pee opening 209 is automatically positioned directly in front of the pee hole 225 of the female user. The tongue fold is approximately 50 mm above the mattress and at the lower end of the vagina. The pee hole 225 is about 90-100 mm above the mattress. The flap 205 is folded inward or outward. When folded outward, the flap, optionally including an adhesive sanitary towel, will be between the buttock cheeks of the user.

The inner face of the rear wall 204 deflects the urine downward.

The user will generally create a slight inclination of the mattress at the location where the single-use container is to be positioned. This will automatically result in a slight inclination of the single-use container of about 10 degrees, so that the pee opening 209 is positioned and oriented in the correct way. The bladder 234 and the anus 235 are also indicated for further clarity.

Turning to fig. 36, the single-use container is shown in use by a male. The penis 233 is inserted into the pee opening 209.

Turning to figure 37, a further variant is shown. The base section 13 is located centrally in the blank. The base section is delimited from the wall section by a base perimeter fold line 30 which has a square shape or rectangular shape.

-24The wall section 11 comprises multiple wall zones 31, 32, 33, 34 which are separate from one another. Each of the front wall zone 31, the rear wall zone 32, the right wall zone 33 and the left wall zone 34 is integrally connected to a side of said centrally located base section via a respective base fold line 40, 41, 42, 43 and extends away from the centrally located base section.

At least two of the wall zones 31, 32, 33, 34, in particular the left and right side wall zones 33, 34, comprise adhesive flaps 58 on either side for forming an adhesive connection between the four wall zones.

The base perimeter fold line 30 is square or rectangular and comprises four corner locations 50, 51, 52, 53. The corner locations are at a distance from the outer edge 199 of the blank. An interconnecting fold line 320 extends away from each corner location and corner sheet sections 322 are provided which connect the adhesive flaps 58 with the adjoining wall zone. The corner sheet sections are connected to said adhesive flap via the interconnecting fold line 320 which extends away from a corner. The corner sheet extensions are connected to an adjoining wall via an opposite fold line 323. The corner sheet sections 322 are intended to be folded about the interconnecting fold line 320 and about the opposite fold line 323 and are intended to be connected with an adhesive connection to the adjoining wall on one side and to be connected to the adhesive flap via an adhesive connection on the other side.

Each corner sheet section 322 connects the adhesive flap 58 to which it is attached to another wall zone. The corner sheet sections 322 may be triangular. The interconnecting fold lines 320 and corner sheet sections 322 ensure that at the corners, a liquid tight adhesive connection is formed during the making of the collapsed single use container.

Turning to figures 38, 39, 40 a method of forming the collapsed single use container from the blank of figure 37 is shown. The front wall zone 31, the rear wall zone 32, the right wall zone 33 and the left wall zone 34 are folded over the base fold lines 40, 41, 42, 43 via which they are connected to the base. Adhesive connections are formed between the front wall zone 31, the rear wall zone 32, the right wall zone 33 and the left wall zone 34, in particular via the adhesive flaps 58.

Second invention - Blank

Turning to figures 41 ,42A and 42B blanks 310 of a second invention are shown, in which the single-use container has straight walls. Many features are similar to the variant of figures 1-18. For conciseness, many of these features are not discussed again herein below and the focus is put on the differences.

-25Figure 41A shows a blank 310 for manufacturing a collapsed single-use container 400, the blank comprising: a base section 13, a wall section 11 and an upper end section 12. The base section is delimited from the wall section by a base perimeter fold line 30. The wall section comprises a front wall zone 31, a rear wall zone 32, a right wall zone 33 and a left wall zone 34.

The side edges 59, 60 of the wall zones 31, 32, 33, 34 are straight and folding lines 80, 81,181 between the front wall zone 31, the rear wall zone 32, the right wall zone 33 and the left wall zone 34 are also straight. The side edges 59, 60 and the folding lines 80, 81,181 are commonly referred to as: sides.

In the embodiment of figure 41 A, the front wall zone and the rear wall zone have a trapezoid shape but this may also be a square or rectangular shape. The right wall zone and the left wall zone have a triangular shape.

A centre 301 of the pee opening 209 or pee opening area 28 is provided at 40-60 percent of a height of the collapsed container.

The blank of figure 41A results in the collapsed single-use container of figure 44.The blank results in a container having straight walls.

Turning to figure 42A, another embodiment is shown. The blank is mirrored with respect to the blanks of figure 1 and 41 .This embodiment comprises roof portions 330 which are attached to the upper ends of the wall zone 31,32,33,34 via roof fold lines 331. Diagonal roof fold lines 335 extend away from corners 336 where the roof fold lines 331 meet the fold lines 80,81,181 between the wall zones.

The blank comprises four roof portions 330. The four roof portions 330 are connected to one another via intermediate roof portions 337, thereby forming a single roof zone extending along the upper end of the wall section 11. The roof fold lines 331 form one interconnected roof fold line extending from a left side of the blank to a right side of the blank.

The intermediate roof portions 337 have the positive effect that the roof of the container to be formed will become liquid tight, because at the corners 336 no gaps will occur.

In the right wall zone 33, two diamond shaped folding sections 7, 7A are provided, one for the base and one for the roof. In the left wall zone 34, two diamond shaped folding portions 8, 8A are provided, one for the base and one for the roof. The diamond shaped sections are defined by folding lines.

-26The blank of figure 42A results in the collapsed single-use container of figure 50.

Turning to figure 42B, the base section 13 is not formed from four distinct portions, but extends as a band across the blank from left to right. Each base portion 44,45,46,47 has a same length L2 measured form the base perimeter fold line 30. The overlap portions 48 are triangular.

The roof portions 330 can be divided in two groups. Short roof portions 330 are connected to the front wall zone 31 and the rear wall zone 330 and longer roof portions 330 are connected to the right wall zone 33 and the left wall zone 34.

The blank of figure 42B results in the collapsed single-use container of figure 48, with a difference that figure 48 shows a vertical flap 150 at the upper end and this vertical flap would not be present when the blank of figure 42B is formed into a collapsed container.

Turning to figures 53, 54, 55, in another embodiment, the blank 310 has a central base section 13. This version of the blank of the second invention is similar to the embodiment of figure 37 for the first invention. The base section 13 is delimited from the wall section by a base perimeter fold line 30 which has a square shape or rectangular shape and comprises four base fold lines 40, 41,42, 43. The wall section comprises four separate parts, i.e. the front wall zone 31, the rear wall zone 32, the right wall zone 33 and the left wall zone 34 which are separate from one another. Each of the front wall zone 31, the rear wall zone 32, the right wall zone 33 and the left wall zone 34 is integrally connected to said centrally located base section via a respective base fold line 40, 41, 42, 43 and extends away from the centrally located base section 13.

Each of the wall zones 31,32, 33, 34 comprises side edges 325. The side edges 325 are straight. The side edges 325 are also referred to as sides.

At the outer ends of the wall zones 31,32,33,34 roof portions 330 are provided which are connected to the wall zones 31,32,33,34 via roof fold lines 331.

A cut-out 333 is provided in the roof portion 330 of front wall zone and the rear wall zone.

-27At least two of the wall zones 31, 32, 33, 34, in particular the left and right side wall zones 33, 34, comprise adhesive flaps 58 for forming an adhesive connection between the four wall zones.

The pee opening 28 is provided in the right side wall 33.

The base perimeter fold line 30 comprises four corners 50, 51, 52, 53. Similar to the embodiment of figure 37, an interconnecting fold line 320 extends away from each corner and corner sheet sections 322 connect the adhesive flaps 58 with the adjoining wall zone, see fig. 53. The corner sheet section 322 which is indicated connects the adhesive flap 58 of the right wall zone 33 with the front wall zone. The corner sheet sections 322 may be triangular. The interconnecting fold lines 320 and corner sheet sections 322 ensure that at the corners, a liquid tight adhesive connection is formed during the making of the collapsed single use container.

The embodiment of figure 53 has square or rectangular front and rear wall zones 31,33 and trapezoid right and left wall zones 33,34. The trapezoid right and left wall zones have a wide base and narrow top. The embodiment of figure 54 has square or rectangular front and rear wall zones 31,33 and trapezoid right and left wall zones 33,34. The trapezoid right and left wall zones have a narrow base and wide top.

Second invention - collapsed container

Turning to figures 43, 44, 45, a collapsed single-use container 400 configured to be expanded into a single-use container is shown. The collapsed single-use container 400 is manufactured from sheet material comprises a base section 13 folded onto itself along a central base fold line 66. The collapsed single-use container 400 comprises a front part 72 comprising a central front part 73 which defines the front wall 201 of the single-use container which is to be formed, a left front part 74 which defines a forward part of the left wall 203 of the single-use container which is to be formed, a right front part 75 which defines a forward part of the right wall 202 of the single-use container which is to be formed,

The collapsed container further comprises a rear part comprising a central rear part which defines the rear wall 204 of the single-use container which is to be formed, a left rear section which defines a rearward part of the left wall 203 of the single-use container which is to be formed, a right rear section which defines a rearward part of the right wall 202 of the

-28single-use container which is to be formed, an upper end where the front part and rear part meet.

The left front part 74 is delimited from the central front part 73 by a left front folding line 80, and the right front part 75 is delimited from the central front part 73 by a right front folding line 81. The left and right front folding lines 80,81 are straight. The same applies to the rear side of the collapsed container.

In the same way as with the previous embodiment, the collapsed single-use container 400 can be expanded into an expanded state by pushing a right edge 82 and a left edge 83 of the collapsed single-use container inward, thereby forming the right and left wall and unfolding the base section into a base.

The collapsed single-use container 400 comprises an upper right edge 84 and a lower right edge 85, and an upper left edge 86 and a lower left edge 87. As indicated in figure 43. the upper right edge 84, the front lower right edge part and the rear lower right edge part form folding lines which can be pushed inwards, thereby forming the straight right wall during the expanding of the collapsible container, and the upper left edge, the front lower left edge part and the rear lower left edge part form folding lines which can be pushed inwards, thereby forming the straight left wall during the expanding of the collapsible container.

The upper right edge 84 and the lower right edge 85 extend at an angle a of 90-150 degrees relative to one another and define a right side corner 91. The upper left edge 86 and the lower left edge 87 extend at an angle a of 90-150 degrees relative to one another and define a left side corner 92. In front view the lower right edge 85 and the lower left edge 87 extend at an angle β of 120-160 degrees relative to a lower base edge 89 of the collapsed single-use container.

The embodiment of figure 43 has a rectangular central front part 73. The embodiment of figure 44 has a trapezoid central front part 73, the base being narrower than the top. The embodiment of figure 44 has a trapezoid central front part 73, the top being narrower than the base.

Similar to the embodiment of figures 1-18, the base is formed by a plurality of base portions folded over one another and connected to one another via an adhesive connection, each base portion being integrally connected via a respective base fold line to one of the walls extending upwardly from the base of the container which is to be formed.

The collapsed single-use container 400 may form a single-use urinal, wherein the central front part 73 may comprise a pee opening, or a pee opening area having a perimeter

-29which is at least partially weakened and is configured to be broken to remove the pee opening area or to fold the pee opening area inward or outward in order to form the pee opening.

The central front part 73 and the central rear part may not be attached to one another at the upper end of the collapsed single-use container. In such an embodiment in the expanded form the upper end of the single-use container can be opened by the user by pushing the left and right corners inward, thereby creating an upper opening.

As indicated in figures 46 and 47 at least one side wall may comprise a pee opening 209, or a pee opening area 28 having a perimeter 208 which is at least partially weakened and is configured to be broken to remove the pee opening area or to fold the pee opening area inward or outward in order to form the pee opening 209.
