Description

[0001] The present invention relates to a bag suitable for attachment, e.g., to a person's torso or as a belt bag. The bag is particularly suitable for use in the medical field, or as a tool bag for medical personnel, especially for holding medical supplies, e.g., medical tools.

[0002] Optionally, the bag includes a belt that can be attached to the bag and by means of which the bag can be attached to the torso, especially in the hip area.

[0003] The bag is characterized by being a single piece and open at the top, in particular having no lid, no zippers and no buttons. State of the art

[0005] US Patent 2013 / 0008933 A1 describes a tool belt to which several belt pouches can be attached. The tools are connected to the belt pouches by cords. The cords are wound and unwound from spools.

[0006] DE 28 41 558 A1 describes a device with a base plate and several quiver-like loops, which is manufactured in one piece using injection molding and can be attached to a belt. Tools can be held by clamping them into the loops.

[0007] US 2003 / 0071099 A1 describes a tool bag that can be fitted onto a rigid container.

[0008] DE 20 2006 004 614 U1 describes a kidney-shaped waist bag into which a foldable toilet seat can be stored.

[0009] It is common practice to store tools in a belt pouch for quick access. However, conventional sewn pouches do not meet the strict hygiene requirements of, for example, a hospital and are therefore unsuitable for medical tools, as dirt and contaminants can accumulate in hard-to-clean areas of the pouch, especially around the seams. Object of the invention

[0010] The invention aims to provide an alternative bag for holding objects, in particular tools, which in particular allows for the secure storage of the objects, especially by clamping, and which is easy to clean, preferably sterilizable, in particular with chemical means, or autoclavable. Description

[0011] The invention solves the problem with the features of the claims and in particular provides a bag comprising or consisting of a first longitudinal wall, a second longitudinal wall arranged at a first distance from the first longitudinal wall, a first narrow wall, a second narrow wall arranged at a second distance from the first narrow wall, and a bottom wall arranged perpendicular to and connected with the first longitudinal wall, second longitudinal wall, first narrow wall, and second narrow wall, optionally at least one loop, and / or optionally belt sections, and / or optionally at least one further longitudinal wall, and / or optionally at least one partition. The first longitudinal wall, second longitudinal wall, first narrow wall, and second narrow wall together form a side wall enclosed around an interior space.

[0012] The first and second longitudinal walls each have a first edge, also referred to here as the top edge, and a corresponding second edge, also referred to here as the bottom edge. They also each have a first and a corresponding second side edge, which connect the top edge to the bottom edge. In the arrangement at the first distance from each other, the first and second longitudinal walls are preferably parallel to each other, optionally congruent, with the same, preferably parallel, orientation of their top edges, bottom edges, first side edges, and second side edges. The first narrow wall connects the correspondingly aligned first side edges of the first and second longitudinal walls, and the second narrow wall connects the corresponding second side edges.The fully enclosed side wall, formed by the first longitudinal wall, second longitudinal wall, first narrow wall, and second narrow wall, has a first edge, also referred to here as the upper edge, and a second edge, also referred to here as the lower edge. The upper edge of the side wall is partially formed by the upper edge of the first or second longitudinal wall, and the lower edge of the side wall is partially formed by the lower edge of the first or second longitudinal wall. In the area of ​​the first or second longitudinal wall, the lower or upper edge of the side wall coincides with its lower or upper edge, respectively. The bottom wall is fully connected to the lower edge of the side wall and, together with it, defines and delimits the interior of the pocket.

[0013] The first distance is also referred to as the depth of the pocket, the second distance as the width of the pocket, and the greatest distance between the bottom and top edges of the side wall as the height of the pocket. The distance between the bottom and top edges of the first and second longitudinal walls is the height of the first and second longitudinal walls, respectively. The top of the pocket is formed by the top edge of the side wall, and the bottom of the pocket by the bottom edge of the side wall and the base wall. Preferably, the top and bottom edges of the side wall are positioned at a constant distance from each other around their entire circumference, so that the pocket has a constant height.

[0014] In general, the walls of the bag are designed so that they curve into one another along their adjacent edges. In particular, intermediate edges or corners are rounded on the inside, e.g., with a radius of curvature of at least 0.1 cm, preferably at least 0.3 cm or at least 0.5 cm, e.g., up to 3 cm or up to 2 cm, e.g., 1 cm. It has been shown that residues of dirt or cleaning agents can be removed more thoroughly and easily from a bag with rounded inner corners and edges, e.g., by machine washing.

[0015] Optionally, the bag has at least one loop on its fully enclosed side wall, preferably on its outer surface facing away from the interior, which is designed for attaching a belt to the bag. The at least one loop can be connected to the side wall in the area of ​​the first longitudinal wall, or, for example, in the area of ​​one of the narrow walls; in particular, the bag can have at least one loop in the area of ​​each of its narrow walls. The at least one loop is preferably formed integrally with at least one of the bag walls.

[0016] Alternatively, the first longitudinal wall can optionally have at least two openings, preferably at least four or at least six openings, more preferably arranged in pairs parallel to each other, each designed to allow the passage of a belt. In this embodiment, the pocket preferably has no loop. The openings are preferably arranged at an angle of at least 30°, more preferably at least 45°, more preferably at least 60°, e.g. up to 90° to the upper edge of the first longitudinal wall, more preferably at a right angle to the upper edge of the first longitudinal wall.

[0017] Alternatively, the belt can optionally be formed as one piece with the pouch, in which case the pouch has no loop. Belts formed as one piece with the pouch preferably have two belt sections attached to opposite sections of the longitudinal walls, narrow walls, or side wall.

[0018] A belt that can be attached to or designed for use with a bag generally has a prong closure at its first end, or alternatively a snap buckle, and preferably belt holes at its opposite second end, configured so that a prong can be inserted through one of the holes to close the belt. The cross-section of the belt can be the same between its first and second ends, preferably the same along its entire length. Alternatively, the cross-section of the belt can widen from its first end towards its second end to its area of ​​greatest cross-section and then taper towards the second end. Preferably, the belt has a waist length of at least 70 cm, more preferably at least 71 cm or at least 76 cm, e.g., up to 180 cm, more preferably up to 150 cm, more preferably up to 130 cm, e.g., 116 cm or 124 cm.The belt's prong or snap buckle is preferably made of an antibacterial material, e.g., aluminum or stainless steel, e.g., with a proportion of silver, titanium, and / or copper, preferably in the form of nanoparticles. Generally, the belt is preferably made of the same material as the bag, optionally in the same or a different color.

[0019] In general, the longitudinal walls of the pocket are curved along their upper and lower edges, preferably independently of each other or identically, with a radius of arc of at least 6 cm, preferably at least 10 cm, more preferably at least 15 cm, at least 20 cm, at least 25 cm, at least 30 cm, or at least 40 cm, e.g., up to 80 cm, up to 70 cm, or up to 60 cm, e.g., 50 cm or 55 cm, and preferably parallel to each other. The first distance is preferably substantially constant over the entire width of the pocket, deviating, e.g., by a maximum of 15%, preferably by a maximum of 10%, from a value for the first distance. In particular, it is preferred that the first distance does not decrease towards the narrow walls of the pocket, or that the first and second longitudinal walls do not converge towards the narrow walls.The bag's curved longitudinal walls, extending along their upper and lower edges, offer the advantage of lying flat against the torso, making it comfortable to wear, especially for extended periods. Experience has shown that a bag with curved, preferably parallel, longitudinal walls exhibits high flexural rigidity, allowing items stored within to be more securely wedged inside.

[0020] The bag is characterized by the fact that its walls and optional loops, and optional belt sections, are all formed in one piece and are not sewn together. Preferably, the bag is manufactured by injection molding, particularly at temperatures between 175 °C and 220 °C. Alternatively, the bag can be manufactured by blow molding, compression molding, 3D printing, extrusion, particularly at temperatures between 140 °C and 180 °C, or, for example, by thermoforming.

[0021] The bottom wall is preferably arranged perpendicular to the side wall. The bag has no wall or lid on its top, so that the cross-section of the bag is at least partially, preferably completely, open towards the top, thus making the interior of the bag open to the surroundings and therefore always accessible. Accordingly, the upper edges of the fully enclosed side wall and the longitudinal and narrow walls form an open cross-section, which is not covered. This allows items to be stored in or removed from the bag with one hand, enabling faster workflows when the bag is used as a tool bag.

[0022] In general, the bag is designed so that items stored inside, such as artery clamps, are securely fastened even during movement, especially when the bag is rotated, e.g., when the bag is rotated overhead while bending over, e.g., clamped between the first and second longitudinal walls, and in particular do not fall out, unless the interior of the bag is closed or covered along the first edges.

[0023] Preferably, the surfaces of the bag walls, particularly those facing the interior, are essentially smooth and have raised areas and / or depressions with a maximum depth of 0.5 mm, preferably 0.3 mm, more preferably 0.2 mm or 0.15 mm. This gives the bag the advantage of reducing dirt accumulation, making it easier to clean. The surfaces of the bag walls are preferably closed and, in particular, do not contain any fabric.

[0024] Preferably, the pouch, and optionally the belt, is made of a material whose surface has antimicrobial properties, is further preferably non-allergenic, and preferably does not accumulate static electricity. The material is preferably rubber-elastic and further preferably puncture-resistant against pointed and / or sharp medical instruments, e.g., against piercing with a medical hollow needle. Generally, the material preferably exhibits high flexural stiffness, depending on the specified materials and wall thicknesses. The material is preferably easy to clean without affecting the structure or shape of the pouch, e.g., machine washable at 40 °C, optionally sterilizable, in particular by UV-C radiation, or by H₂O₂, e.g., at a concentration of 1.5 vol% in water, with rinsing for 5 minutes, or by autoclaving, e.g., at 121 °C for at least 20 minutes.

[0025] The material can be a plastic, in particular a foamed plastic, e.g., ethylene-vinyl acetate copolymer (EVA) or silicone rubber, optionally with a filler component, which may, for example, comprise or consist of walnut shell fragments, preferably ground or grated, and further optionally with embedded dye. Preferably, the bag material contains the filler at a concentration of at least 1% by weight, at least 2% by weight, at least 3% by weight, or at least 5% by weight, more preferably up to 30% by weight, up to 25% by weight, up to 20% by weight, or up to 15% by weight, e.g., 10% by weight or 20% by weight. Preferably, all walls and loops are made of the same material. By embedding dye directly into the material, the bag has the advantage that it can be marked, for example, for a specific use, or that different embodiments of individual bags can be distinguished by different colors.

[0026] It is generally preferred that the bag has a depth or first spacing of at least 0.2 cm, preferably at least 0.5 cm, at least 1 cm, at least 1.5 cm, at least 2 cm, at least 3 cm, at least 4 cm, at least 5 cm or at least 6 cm, e.g. up to 15 cm, preferably up to 12 cm or up to 9 cm, e.g. a depth of 1 to 6 cm, furthermore a width of at least 10 cm, preferably at least 15 cm, at least 20 cm, at least 25 cm, e.g. up to 50 cm, preferably up to 45 cm, up to 40 cm or up to 35 cm, e.g. a width of 28 to 32 cm, as well as a height of at least 5 cm, preferably at least 8 cm, at least 10 cm, at least 12 cm or at least 15 cm, e.g. up to 30 cm, up to 25 cm or up to 22 cm, e.g. a height of 19 to 20 cm.

[0027] All distances are given as clear distances.

[0028] The surrounding side wall of the bag has a wall thickness of at least 0.7 mm, preferably at least 2 mm or at least 4 mm, e.g., up to 10 mm, and in particular a wall thickness between 6 and 10 mm. The bottom wall has a wall thickness of at least 1.3 mm, preferably at least 4 mm or at least 6 mm, e.g., up to 14 mm, and in particular a wall thickness between 8 and 12 mm. The loops and other walls of the bag each have, independently of one another or identically, a wall thickness of at least 0.4 mm, preferably at least 2 mm or at least 4 mm, e.g., up to 10 mm, and in particular a wall thickness between 6 and 10 mm. The optional belt or belt sections have a thickness of at least 1 mm, preferably at least 4 mm, e.g., up to 10 mm.This design ensures that items to be stored in the bag, especially medical tools, are wedged in the spaces between the longitudinal walls and thus secured within the bag, preventing them from falling out, particularly when the bag is rotated upside down.

[0029] In a particularly preferred embodiment, all walls of the pocket except for the bottom wall, in particular the circumferential side wall, the optional at least one further side wall and the optional at least one partition wall, each have the same wall thickness, and the bottom wall has a greater wall thickness, e.g. greater by 1 to 5 mm than the wall thickness of the other walls.

[0030] It is particularly preferred that each of the pocket walls has a constant wall thickness across its surface. Alternatively, the wall thicknesses of the pocket walls can be tapered, either independently or identically, particularly towards the bottom wall or towards the top of the pocket, or, for example, have the same thickness over the entire height of the pocket, or taper from the bottom wall towards the top of the pocket to a region of least thickness and then thicken towards the top of the pocket, or thicken from the bottom wall towards the top of the pocket to a region of greatest thickness and then taper towards the top of the pocket.

[0031] It is generally preferred that the longitudinal walls of the pocket are essentially straight in the area between the top and bottom edges. Accordingly, the pocket preferably has an internal and / or external cross-section that is constant over its height.

[0032] Optionally, the bag has at least one further longitudinal wall with a lower edge, an opposite upper edge, a first side edge, and an opposite second side edge, which is connected to the first narrow wall at its first side edge and to the second narrow wall at its second side edge and is configured to divide the interior of the bag into at least two sections. It is preferred that the at least one further longitudinal wall is connected to the bottom wall at its lower edge, or alternatively, extends only over a portion of the height of the side wall, e.g., only in the third of the bag height adjacent to the upper edge, and that its lower edge is positioned at a distance from the bottom wall. It is further preferred that the at least one further longitudinal wall is flush at its upper edge with an edge of the first longitudinal wall, the second longitudinal wall, or the side wall.In this case, at least one further longitudinal wall is arranged at a third distance from the first longitudinal wall, preferably parallel to it, wherein the third distance is smaller than the second distance and preferably is essentially the same across the entire width of the pocket, and in particular does not taper towards the narrow walls of the pocket. It has been shown that a pocket with at least one further longitudinal wall has a higher bending stiffness than a pocket without the at least one further longitudinal wall, so that objects can be stored more reliably in the pocket, in particular clamped in place.

[0033] Optionally, the bag has at least one partition wall with a lower edge, an opposite upper edge, a first side edge, and an opposite second side edge, the first side edge of which is connected to one of the first, second, or further longitudinal walls, and the second side edge of which is connected to another of the first, second, or further longitudinal walls, and which is configured to divide the interior of the bag into at least two sections. Preferably, the at least one partition wall is connected to the bottom wall at its lower edge, or alternatively, extends only over a portion of the height of the side wall, e.g., only in the third of the bag height adjacent to the upper edge, and its lower edge is positioned at a distance from the bottom wall. More preferably, the at least one partition wall is flush with the first and / or second and / or further longitudinal walls at its upper edge.The at least one partition is preferably arranged at right angles to the first and / or second and / or subsequent longitudinal wall. It has been shown that a bag with at least one partition has a higher bending stiffness than a bag without the at least one partition, so that objects can be stored more reliably in the bag, in particular wedged in place.

[0034] In one embodiment, the bag can have several partitions which, either independently or identically, are arranged at a distance of at least 3 cm, preferably at least 5 cm, e.g. up to 20 cm or up to 15 cm from each other, dividing the interior of the bag into several sections. In this embodiment, the bag is particularly rigid and therefore especially suitable for clamping tools.

[0035] Optionally, the bottom wall has at least one opening, preferably designed as a perforation, preferably with a round cross-section, and configured to allow fluid contained in the pocket, e.g., cleaning fluid, to drain through the opening. In the embodiment with the interior of the pocket divided into at least two sections, at least one opening, preferably exactly one opening, is preferably arranged in the bottom wall of each section.

[0036] Optionally, at least one bottom loop is arranged on the outer side of the bottom wall facing away from the interior. This loop is designed so that when the bag is hung by the loop, it is positioned upside down, allowing any fluid inside, such as cleaning fluid, to drain out. The bottom loop is preferably formed integrally with the bottom wall or bag.

[0037] In one embodiment, the pocket has at least one opening on its circumferential side wall with an opening cross-section, preferably designed as a perforation, and optionally an elastic projection with a projection cross-section configured to engage with and lock into the at least one opening. For example, the optional elastic projection can have a thickening at its end opposite the pocket, the cross-section of which is larger than the opening cross-section, with the projection cross-section being smaller than the opening cross-section. The optional elastic projection is preferably formed integrally with the pocket. In this embodiment, the pocket has the advantage that, for example, a key ring can be hooked onto the optional elastic projection, or alternatively, into the opening on the circumferential side wall, and thus attached to the pocket.

[0038] In another embodiment, the second longitudinal wall is lower than the first longitudinal wall. In this embodiment, the bag has the advantage that items can be stored more easily in the bag.

[0039] According to the invention, a collar is arranged at the upper edge of the second longitudinal wall, preferably across the entire width of the bag, and is formed integrally with the second longitudinal wall. The collar projects away from the first longitudinal wall and / or the bottom wall, preferably at an angle of at least 30° to 80° to the second longitudinal wall, and has a collar height of at least 1 cm, preferably at least 2 cm or at least 3 cm, e.g., up to 5 cm. At least one further collar may be arranged on at least one of the other longitudinal walls. With a collar, the bag has the advantage of enabling reliable storage of items and simultaneously exhibiting higher bending stiffness than a bag without a collar.

[0040] In one embodiment, the optional loop can extend beyond the top edge of the first longitudinal wall, e.g., by at least 2 cm, preferably by at least 3 cm, e.g., by up to 10 cm or up to 8 cm. In this embodiment, the bag has the advantage that an attached belt, preferably puncture-resistant, protects the torso, e.g., from puncture or cut injuries, and also facilitates the storage of items in the bag.

[0041] Optionally, the pocket has, on at least one of its longitudinal walls, particularly on its convex surface, at least one extension with an extension longitudinal wall at a fourth distance, preferably parallel, to the at least one longitudinal wall, two extension narrow walls connecting the opposite sides of the extension longitudinal wall to the longitudinal wall, wherein the extension longitudinal wall together with the extension narrow walls forms a partially circumferential extension wall with an upper edge and a lower edge. A base wall of the extension is fully connected to the lower edge of the extension wall. The extension longitudinal wall preferably extends only partially over the width and / or height of the pocket, such that its upper edge and / or its lower edge and / or at least one of the extension narrow walls is projected beyond the at least one longitudinal wall.In this embodiment, the walls of the attachment, namely the longitudinal wall, narrow walls, and bottom wall, are formed integrally with the at least one longitudinal wall and have rounded corners and edges. The bottom wall preferably has at least one opening designed to allow fluid contained in the attachment to drain through. The fourth distance is preferably at least 0.5 cm to 5 cm. The longitudinal wall, bottom wall, and narrow walls each have a thickness of at least 0.5 mm to 10 mm, preferably the same thickness as the surrounding side wall. In an embodiment of the pocket with at least two attachments, the attachments can each be arranged at a distance from one another, or two attachments can be connected to each other via a common narrow wall, e.g.The second septum of a first attachment can simultaneously form the first septum of a second attachment.

[0042] The bag can have a combination of features from different designs.

[0043] The invention will now be described in more detail with regard to the figures that are in - Fig. 1. A bag under supervision, - Fig. 2 pockets in side cross-sectional view, - Fig. 3 pockets in side cross-sectional view, - Fig. 4 a bag under supervision, and in - Fig. 5. A bag in side view to show. In the figures, identical reference numbers denote functionally equivalent elements.

[0044] Fig. Figure 1 shows a pocket in plan view with a first longitudinal wall 1, a second longitudinal wall 2 opposite it at a first distance 11, and a first narrow wall 3 and a second narrow wall 4 opposite it at a second distance 12, which together form a side wall 1, 2, 3, 4 of the pocket that is enclosed around an interior space. The first and second longitudinal walls 1, 2 are to be arranged according to the Fig. The first longitudinal wall 1 is arranged parallel to each other. The first narrow wall 3 connects the first side edge 1c of the first longitudinal wall 1 with the first side edge 2c of the second longitudinal wall 2. The second narrow wall 4 connects the second side edge 1d of the first longitudinal wall 1 with the second side edge 2d of the second longitudinal wall 2. A bottom wall 6 is fully connected to the lower edge 1b, 2b of the side walls 1, 2, 3, 4 at a right angle. Two loops 7 are arranged on the first longitudinal wall 1, designed for attaching a belt. An opening 8 is arranged in the bottom wall 6, designed to allow fluid contained in the bag to drain out through the opening.

[0045] According to the Fig. 1 the first longitudinal wall 1 and second longitudinal wall 2 of the pocket are curved, and the first distance 11 is essentially the same across the entire width of the pocket.

[0046] Fig. Figure 2 shows in A) a lateral cross-sectional view of the in Fig. 1 shown pocket (not according to the invention). At the first distance 11 and according to Fig. 2 A) Parallel to a first longitudinal wall 1 with an upper edge 1a and an opposite lower edge 1b, a second longitudinal wall 2 with an upper edge 2a and a lower edge 2b is arranged. A bottom wall 6, arranged perpendicular to the first and second longitudinal walls 1, 2, connects their lower edges 1b, 2b. A loop 7 is arranged on the first longitudinal wall 1. In B), a non-inventive embodiment is shown in a side cross-sectional view with a first longitudinal wall 1, a second longitudinal wall 2, an intermediate bottom wall 6, and a loop 7, in which the loop 7 projects beyond the upper edge of the first longitudinal wall 1 opposite the bottom wall 6, so that a belt attached to it provides additional protection against punctures or cuts.

[0047] The in Fig. 2 C) The bag shown in a side cross-sectional view (not according to the invention) has a first longitudinal wall 1, a second longitudinal wall 2 at a first distance 11 therefrom, and a bottom wall 6 in between. In the embodiment shown here, the height of the bag 13 is equal to the height of the first longitudinal wall 13a, namely the distance between the upper edge 1a and the lower edge 1b of the first longitudinal wall 1. In the embodiment shown here, the second longitudinal wall 2 has a lower height 13b, shown as the distance between the upper edge 2a and the lower edge 2b of the second longitudinal wall 2. Due to the lower height 13b of the second longitudinal wall 2, items can be stored more easily in the bag. In the embodiment according to the invention shown in D), a collar 9 is arranged at the upper edge 2a of the second longitudinal wall 2, which is formed integrally with the second longitudinal wall 2. The collar 9 projects away from the first longitudinal wall 1 and from the bottom wall 6.

[0048] Fig. Figure 3 shows in A) a pocket (not according to the invention) with a first longitudinal wall 1, a second longitudinal wall 2 at a first distance 11 thereto, and a bottom wall 6 situated between them. At a third distance 14 from the first longitudinal wall 1, a further longitudinal wall 10 is arranged with an upper edge 10a and a lower edge 10b and is connected to the bottom wall 6 at its lower edge 10b. The third distance 14 is smaller than the first distance 11. The upper edge 10a of the further longitudinal wall is flush with the upper edges 1a, 2a of the first and second longitudinal walls 1, 2.

[0049] In Fig. Figure 3B) shows a side cross-sectional view of a pocket (not according to the invention) with an attachment 22 on the second longitudinal wall 2. An attachment longitudinal wall 22 is arranged at a distance 25 from the second longitudinal wall 2 and is connected to it at its lower edge 22b via an attachment bottom wall 23, the intermediate corners and edges being rounded. According to the Fig. 3 B) the top longitudinal wall 22 is overtopped at its upper edge 22a and at its lower edge 22b by the upper edge 2a and the lower edge 2b of the second longitudinal wall 2 respectively.

[0050] The Fig. Figure 4 shows a preferred embodiment of the bag with a first longitudinal wall 1, a second longitudinal wall 2 at a first distance 11 therefrom, a further longitudinal wall 10 at a third distance 14 from the first longitudinal wall 1, and a bottom wall 6 connecting the first, second, and further longitudinal walls 1, 2, 10, which together define the interior of the bag, in a top view. The first, second, and further longitudinal walls 1, 2 are shown in the diagram. Fig. 4 are arranged essentially parallel to each other. The first narrow wall 3 connects the first side edge 1c of the first longitudinal wall 1 with the first side edge 10c of the second side wall 10 and the first side edge 2c of the second longitudinal wall 2. The second narrow wall 4 connects the second side edge 1d of the first longitudinal wall 1 with the second side edge 10d of the second side wall 10 and the second side edge 2d of the second longitudinal wall 2. On the side of the first longitudinal wall 1 facing away from the pocket, two loops 7 are arranged, which are designed for attaching a belt. Inside the pocket, three partitions 20 are arranged, each of which is connected at its first side edge 20c to one of the first, second, or second longitudinal wall 1, 2, 10 and at its second side edge 20d to another of the first, second, or second longitudinal wall 1, 2, 10, with the first longitudinal wall 1 being connected to the second longitudinal wall 10, and the third to the second longitudinal wall 10, respectively.The further longitudinal wall 10 connects to the second longitudinal wall 2, thereby dividing the interior of the bag into five sections 15. In each section 15, the bottom wall 6 of the bag has an opening 8 for the drainage of fluid contained in the bag.

[0051] Furthermore, according to Fig. 4.
