Technical field

[0001] The invention relates to a storage box according to the preamble of claim 1 and claim 2. State of the art

[0002] Storage boxes of this type are already known and commonly used in a wide variety of forms and designs.

[0003] The application area for such lightweight plastic boxes is the household, for example in the children's room to tidy up children's toys or in the storage room, in the basement, in the garage, in the office the box helps to keep all areas tidy without much effort.

[0004] These boxes consist of a box base, container walls standing on the ground, whereby the base and the container walls define a storage area of ​​the container, wherein casters are arranged on the underside of the base for moving the container in such a way that the box can be moved longitudinally or transversely depending on the position of the casters.

[0005] The storage area of ​​the box can be closed with a lid, with the locking mechanism being located on the lid or on the container walls and simultaneously serving as a carrying handle. Object of the invention

[0006] The object of the present invention is to provide a storage box in various sizes, which is intended for use not only in the household but also in crafts and trades, and which can be equipped with a tight-fitting lid with a new locking system or in combination with a new attachable carrying handle function in order to expand the range of applications of the box, in addition the load-bearing surfaces for the casters are to be enlarged and an efficient caster positioning is to be developed in order to guarantee the lateral and longitudinal movement of the box and to improve the user-friendliness of handling. Solution to the task

[0007] The features according to claims 1 and 2 lead to the solution of the problem.

[0008] Advantageous embodiments are described in the dependent claims.

[0009] According to the invention, a plastic storage box with a reversibly attachable plastic lid is provided. "Reversibly attachable" in this context means that the lid can be removed, replaced, and thereby connected to the storage box in order to close it. A locking element of the lid and / or the storage box is designed to be spring-loaded and reversibly detachable.

[0010] The storage box has a substantially rectangular base. Substantially means that it is a rectangular shape with rounded corners.

[0011] Container walls extend all around from the container base, with a ribbed structure formed on one side of the container base. The underside of the container base refers to the side of the container base that faces away from the container walls.

[0012] The storage box according to the invention has a one-piece storage container with a container base and four container walls attached to the container base on one side, wherein the wall structure of the four container walls is alternately concave and convex.

[0013] The container base has a ribbed structure, the ribbed structure being designed to serve as stability ribs for the container and as a material filling aid in injection molding production.

[0014] The container wall between the individual ribs can be very thin, as the stability of the box is achieved through the rib structure in the base and through the alternation of the concave and convex wall structure of the container walls, and the four container walls are connected to each other via four corner rounds to form a 4-sided shape, giving the system additional stability.

[0015] The container walls are larger at the longitudinal edges of the container base than at the end edges, with the container walls having a rounded corner. "Larger" here means that the longitudinal edges are both longer and have a larger surface area than the end edges.

[0016] The upper edge of the four container walls in the opening area of ​​the storage box forms a circumferential rim with a flat surface for the lid.

[0017] The four container walls of the storage box may also incorporate recessed handles or openings for manual use.

[0018] The short, recessed ribbed wall, which is set back towards the center of the container in the corner area and corner roundings on the outer side of the container base, is arranged on the short and long container walls, whereby the recessed short ribbed wall lengths at the ribbed wall end of the two container walls are connected via a geometric quadrilateral with a ribbed wall that runs at a partial 45° angle, thus forming a closed support geometry of the container, so that this geometry accommodates the roller mounting for the longitudinal and transverse movement of the container in some sizes of the storage box in the four corner areas.

[0019] Within the support geometry in the four bottom-side corners and within the recessed short rib wall lengths on the short and long container walls, the roller load support ribs are integrated as roller axle supports on each side and arranged with a keyhole geometry and thickening eyes, whereby the roller load support ribs are also connected as support ribs to the recessed two short rib wall lengths.

[0020] The ribbed structure in the corner areas features container foot ribs, with the lid or storage box having a locking element that secures the lid to the storage box. The geometry of the container foot ribs is designed to be as open as possible to prevent problems caused by contamination. This open design, described below, also reduces problems when the storage box rolls.

[0021] The closure element arranged on the lid, which is designed with a plastic flat leaf spring integrated into the closure and geometrically adapted to the handling and embedded in the closure wall, limited by lateral functional openings, and the plastic flat leaf spring functionally performs the closing and sealing function of the lid in conjunction with the container.

[0022] Similarly, for various container sizes, an attachable locking and carrying handle can be used on the short container walls, i.e., the end faces of the storage box. This handle is mounted via two openings in the vertical ribs under the surrounding edge of the container. The handle wall is designed as a double flat leaf spring element, so that the handle can also be used as a locking element for the lid in conjunction with the storage container, in order to take over the spring function and the locking preload in the locking system and to compensate for height tolerances.

[0023] The lid is designed as a sealed element in conjunction with the storage container to also store or transport liquid media.

[0024] Furthermore, variants of the storage box must be upgradeable with mobile, dense partitions so that the storage space can be separated or subdivided several times along the short side.

[0025] In order to allow the partitions to be inserted into the storage space, the base plate of the storage box has tight, elongated insert pockets, and the upper circumferential edge of the box also has short, elongated, tight insert pockets or grooves running towards the bottom.

[0026] The lid has a leaf spring locking element, wherein the leaf spring locking element projects beyond a container rim, preferably beyond the front edge, in the closed position, wherein a one-piece co-extruded flat leaf spring geometry is arranged between the lid and the leaf spring locking element, wherein the flat leaf spring geometry is formed one-piece with the lid or the leaf spring locking element, wherein the leaf spring locking element has a locking cam which engages in a container recess of the container rim in the closed position.

[0027] The one-piece, co-extruded flat leaf spring geometry can be part of the lid or the leaf spring locking element. It ensures distortion-free handling when opening and closing the storage box. In conjunction with the cam, it forms a slightly pre-tensioned locking mechanism for the lid on the storage box.

[0028] In a further embodiment of the invention, the locking element is a pivotably arranged locking and carrying handle of the storage box. The locking and carrying handle forms a one-piece extruded plastic flat leaf spring which, in the locked position, presses against a lid edge. The locking and carrying handle also forms a further locking lug, which, in the locked position, engages in a recess in the lid. The embodiments of the leaf spring locking element and the one-piece extruded flat leaf spring geometry also apply to the locking and carrying handle and the plastic flat leaf spring, as they only form the arrangement of a locking mechanism on the storage box and not on the lid.

[0029] The attachable locking and carrying handle on the container seals and, when the box is closed, presses the lid with the sealing spring element onto the surrounding support edge of the storage box via the spring function and spring preload, using the integrated locking element, designed as a double plastic flat leaf spring and locking latch, and also to compensate for any possible tolerance differences in the overall height.

[0030] Furthermore, the lid features a circumferential sealing bead, designed to press the lid firmly against the storage box when closed. By placing the lid on the open storage box and closing it, the spring-loaded sealing bead, located on the inner surface of the lid, creates a seal. Recessed grips in the walls of the storage box ensure easy handling.

[0031] By placing the lid on the open storage box with a circumferential springy sealing bead, arranged on the inner surface of the lid, which is geometrically designed in cross-section as a springy triangular element, a seal is created on the flat surface of the circumferential flat support edge of the storage box.

[0032] The container foot ribs have a circumferential frame in the form of a polygonal geometry, wherein three roller mounting ribs are arranged within the polygonal geometry, wherein a first of the roller mounting ribs is arranged extending from the front edge to the longitudinal edge, a second of the roller mounting ribs branches off from the longitudinal edge and extends to the opposite longitudinal edge and transitions within the polygonal geometry into a parallel to the branched longitudinal edge until it merges into the polygonal geometry, and a third of the roller mounting ribs branches off from the front edge and extends to the opposite front edge and transitions within the polygonal geometry into a parallel to the branched front edge until it merges into the polygonal geometry.

[0033] The roller mounting ribs each have a roller bearing towards the longitudinal edge of the container bottom and towards the end edge of the container bottom, wherein the roller mounts are provided in the form of a keyhole geometry recessed into a bearing eye, suitable for receiving a roller with a roller axle in a roller axle mount.

[0034] In particular, the bearing eyes of the roller bearings feature an increased load-bearing surface due to a wider rib profile. The respective bearing eyes are arranged flush with the load-bearing ribs and incorporate a keyhole geometry.

[0035] The roller axle bearing consists of two opposing roller load-bearing ribs and is designed as a parallel rib at a distance of one roller width to accommodate the one-piece axle, which is also designed as a roller.

[0036] To allow the user to manually mount the rollers with rigid axles on both sides into the roller bearing as desired for longitudinal or transverse movement and to anchor them via a snap-in effect, the roller bearing is designed as a keyhole geometry, with the axle support surface being enlarged in that area by a wall thickness reinforcement as an axle receiving eye.

[0037] With this easy-to-install caster mount and open arrangement under the container base, it is possible for the casters to be connected and positioned directly in the recessed open corner area of ​​the short and long outer walls of the container, so that the storage box can be moved laterally or longitudinally depending on the caster positioning.

[0038] The open positioning of the roller bearings, with the rollers on the outer side of the container base in the corner area without an additional constricting cage (i.e., there is no direct cage around the rollers), thus limiting the accumulation of dirt particles directly around the rollers. In box variants without rollers, the closed support geometry serves as the base of the storage box.

[0039] The recessed support geometry and the roller mounting ribs ensure good stability even on uneven surfaces, while the rib width of the large-area support geometry distributes even large loads across the surface.

[0040] The storage box system will be available in various sizes and designs, with and without casters, and with attachable carrying handles or simply with recessed grips or handles featuring a new spring-loaded locking mechanism, a sealing function in the lid, and a spring-loaded locking element directly on the lid. Furthermore, the storage box will be available with or without dividers.

[0041] Furthermore, the leaf spring locking element has a limiting slot, which allows the locking and carrying handle to be opened and closed without distortion.

[0042] The plastic flat leaf spring is part of a flat leaf spring band of the locking and carrying handle, whereby in the closed position it has a constriction that is convex towards the storage box.

[0043] The at least two insertion pockets arranged on the transverse axis of the floor are designed to be tightly enclosed downwards towards the box storage surface in order to securely and tightly fix the partition pins.

[0044] These at least four insertion or insertion pockets for a partition (two in the base plate and one each on the side wall of the surrounding box edge) fix the partition, which is mounted as needed, and allow it to be removed from the box container.

[0045] In the version without sliding rollers, the support geometry of the roller mounts in the four container bottom corners of the box is the box support surface or the box feet to the storage surface. Character description

[0046] Figure 1Figure 1 shows a 3D main view of the storage box 1 according to the invention with the removable, tight lid 2, wherein a leaf spring locking element 3 is arranged on each of the two short sides of the lid 2.

[0047] To give the lid 2 planar stability, it is framed with a circumferential multi-surface cover rim 4, wherein a circumferential spring-loaded sealing bead 6 is arranged on the upper flat surface of the cover rim on the inside facing the container 5. The lid 2 thus presses the circumferential sealing bead 6 against the storage box 1 in a sealing position.

[0048] The container 5 consists of a container base 7 and four container walls 8.1, 8.2, 8.3, 8.4. The container base 7 has a ribbed structure 9. The four container walls are formed integrally with the container base 7 and are connected to each other at the corner radii 10, with the wall structure of the four container walls 8.1, 8.2, 8.3, 8.4 being alternately concave and convex.

[0049] Due to the concave, convex wall structure, there is a usable grip recess 12 on the two short wall sides 8.3 and 8.4, while the concave depressions 13 on the container walls 8.1 and 8.2, created by the alternating wall structures, are less pronounced and are not designed as grip recesses.

[0050] The recessed short container foot ribs 14 in the corner area and corner roundings 10 on the outside of the container form a closed polygonal geometry 24 on the underside 15 of the container base.

[0051] The leaf spring locking element 3 is integrally connected to the lid 2 and integrated into the cover rim 4.

[0052] The locking element 3 acquires its spring locking function through the simple flat leaf spring geometry 17 and the limiting slots 16.

[0053] Figure 1 Figure 1 shows a view of the storage box 1 according to the invention with a reversibly attachable lid 2, wherein the storage box 1 has a rectangular container base 7 with rounded corner areas, from which container walls 8.1 to 8.4 project all around and on the other hand are attached to a container base underside 15 (see Figure 1). Figure 7ff.) a ribbed structure 9 is formed, wherein the container walls 8.1 to 8.4 are larger at the longitudinal edges (8.1, 8.2) of the container base 7 than at the end edges (8.3, 8.4), wherein the container walls 8.1 to 8.4 have a corner rounding 10 in the connecting corner areas, wherein the ribbed structure 9 has container foot ribs 14 in the corner areas, wherein the lid 2 has a locking element, wherein the locking element secures the lid 2 to the storage box 1.

[0054] For this purpose, the lid 2 has a leaf spring locking element 3, wherein the leaf spring locking element 3 projects beyond a container rim 21 in the closed position (see Figures 2 to 5), wherein an integrally co-extruded flat leaf spring geometry 17 is arranged between the lid 2 and the leaf spring locking element 3, wherein the flat leaf spring geometry 17 is formed integrally with the leaf spring locking element 3 in this embodiment, wherein the leaf spring locking element 3 has a locking cam 19 which, in the closed position, engages in a container recess 20 of the container rim 21.

[0055] Figure 2 shows a partial view of the storage box 1 according to the invention in the area of ​​the leaf spring locking element 3 with the two limiting slots 16, which are arranged for the spring movement of the handle tab 18 at the end of the handle area.

[0056] The leaf spring locking element 3 is arranged in the center of each of the two short sides of the lid 2 in combination with the container walls 8.3 and 8.4 and directly above the concave grip recess 12 of the container 5.

[0057] Figure 3 shows a partial cross-section of the storage box 1 according to the invention in the area of ​​the leaf spring locking element 3 with the locking cam 19, which engages resiliently in the container recess 20 via the flat leaf spring geometry 17.

[0058] The lid 2 can be unlocked and opened manually via the handle tab 18.

[0059] The locking cam 19 is integrally connected to the handle tab 18 and can be moved via the flat leaf spring geometry 17, which is designed as a leaf spring and utilizes the inherent tension of the plastic wall, whereby it returns itself to the locking position via the inherent tension.

[0060] The multi-surface lid geometry with the cover edge 4 gives the lid construction the necessary torsional and deformation stability to also cover the container edge 21 flush and to seal it via a springy sealing bead 6.

[0061] Embedded in the container walls 8.3 and 8.4 is the recessed handle 12, which, with its shape, enables the system to be carried comfortably and at the same time guarantees high stability.

[0062] Figure 4 and Figure 5 show a partial cross-section of the storage box 1 according to the invention in the area of ​​the circumferential sealing bead 6, wherein the Figure 5 The sealing bead 6 is resiliently supported by an additional spring geometry 22 to compensate for tolerances. The sealing bead 6, arranged circumferentially under the upper planar surface of the cover rim 4, seals the system against the atmosphere to the planar surface of the container rim 21.

[0063] Figure 6 shows a 3D main view of the container 5 without lid 2 of the storage box 1 according to the invention.

[0064] The container 5 consists of a container base 7 and four container walls 8.1, 8.2, 8.3, 8.4, wherein the four container walls 8.1, 8.2, 8.3, 8.4 are formed in one piece with the container base 7 and are connected to each other at the corner radii 10.

[0065] The concave and convex side wall structure 11 over the four container walls of the container gives the container system the required stability and generates grip recesses 12 on the short sides 8.3 and 8.4.

[0066] The upper container rim 21 with the stabilizing ribs 23 gives the container 5 the required torsional rigidity and deformation resistance and presses on the circumferential flat surface against the circumferential sealing bead 6 over the lid cover rim 4 to seal the system.

[0067] The short container foot ribs 14 in the corner area, which project back from the container walls, and the corner roundings 10 on the outside of the container form a closed polygonal geometry 24 on the underside 15 of the container base.

[0068] Figure 7 shows a top view of the container base 7 of the storage box 1 according to the invention.

[0069] It can be clearly seen that the container foot ribs 14 have a circumferential frame in the form of a polygonal geometry 24, wherein three roller mounting ribs 25 are arranged within the polygonal geometry 24, wherein a first of the roller mounting ribs 25 is arranged extending from the end edge of the short container walls 8.3, 8.4 to the longitudinal edge of the long container walls 8.1, 8.2, a second of the roller mounting ribs 25 branches off from the longitudinal edge and extends to the opposite longitudinal edge and transitions within the polygonal geometry 24 into a parallel to the branched longitudinal edge until it merges into the polygonal geometry 24, and a third of the roller mounting ribs 25 branches off from the end edge and extends to the opposite end edge and transitions within the polygonal geometry 24 into a parallel to the branched end edge until it merges into the polygonal geometry 24.

[0070] Additionally, it can be seen in Figures 7ff. that roller mounting ribs 25 each have a roller bearing 27 to the longitudinal edge of the container base 7 and to the front edge of the container base 7, wherein the roller receptacles 28 are provided in the form of a keyhole geometry 32 embedded in a bearing eye 30, suitable to accommodate a roller 26 with a roller axle 29 in a roller axle receptacle 31.

[0071] It has also been shown that the bearing eyes 30 of the roller bearings 27 have an increased load-bearing area due to an increased rib width.

[0072] Furthermore, it can be seen that the bearing eye 30 is arranged flat on the load-bearing ribs 25 with embedded keyhole geometry 32.

[0073] The container base 7 has an intersecting rib structure 9, which connects with the recessed container foot ribs 14 in the corner area of ​​the container base 7 on the underside 15 of the container base with the polygonal geometry 24.

[0074] This rib structure 9 and rib geometry in conjunction with the polygonal geometry 24 in the four corner areas of the container base 7 and container base underside 15 reduces the wall stresses that arise during injection molding and thus provides the basis for manufacturing the four container walls 8.1, 8.2, 8.3, 8.4 in one piece with the container base 7.

[0075] The concave and convex side wall structures 11 in conjunction with the bottom underside rib structure 9 and 24 enable the manufacture of torsion-resistant and stable storage boxes 1 with a capacity of approximately 30 liters to approximately 150 liters, which can be used as a robust unit.

[0076] In the corner areas and within the polygonal geometry 24, the roller mounting ribs 25 are arranged, which accommodate the rollers 26 depending on the mounting for the transverse or longitudinal movement of the storage box 1.

[0077] The open arrangement and positioning of the roller bearing 27 for the longitudinal or transverse movement of the storage box 1 results in user-friendly, assembly-friendly handling of the rollers 26 to be mounted by the user.

[0078] Due to the different height of the rib structure 9 to the polygonal geometry 24 in the corner areas of the container base 7 and the underside of the container base 15, the polygonal geometry 24 with the container foot ribs 14 results in secure stability with high load transfer to the base of the storage box 1.

[0079] The Figures 8 and 9show a top view of the container base 7 of the storage box 1 according to the invention with the casters 26 mounted by the user.

[0080] Depending on the user's wishes, the rollers 26 can be manually snapped into the roller bearing 27 for longitudinal or transverse movement of the storage box 1 via simple handling into the roller receptacle 28.

[0081] The Figure 8 shows the mounted casters 26 for lateral movement of the storage box 1 and the Figure 9 shows the mounted rollers 26 for longitudinal movement of the storage box 1.

[0082] Figure 10 shows a partial top view of the container base 7 in the corner area with the polygonal geometry 24 of the storage box 1 according to the invention.

[0083] The roller mounting ribs 25 are connected to the polygonal geometry 24 and guarantee a compact, torsion-free unit so that the rollers 26 have a centrally fixed seat in the roller bearing 27 with the roller axle 29.

[0084] The widened roller bearing 27, with additional doubled bearing eyes 30, enlarges the roller axle mount 31, thus achieving a longer service life of the roller bearing 27 even under increased load.

[0085] Figure 11 Figure 1 shows a partial view of the roller bearing 27, embedded in the roller mounting ribs 25 of the storage box 1 according to the invention. The roller mounting 28 is designed as a keyhole geometry 32 so that the roller axle 29 with the rollers 26 can be manually mounted and snapped into place via the insertion ramp of the keyhole geometry 32.

[0086] By doubling the wall thickness across the width of the roller mounting ribs 25 with additional bearing eyes 30, the roller axle mounting surface 31 is enlarged and made more resilient.

[0087] Figure 12 Figure 1 shows a 3D main view of a further embodiment of the storage box 1 according to the invention with a removable lid 2, but with attachable locking and carrying handles 33, which are arranged to be manually attached to the short container walls 8.3 and 8.4 of the container 5.

[0088] In the embodiment shown here, the locking element is a pivotably arranged locking and carrying handle 33, wherein the locking and carrying handle 33 forms a one-piece co-extruded plastic flat leaf spring 34 which, in the locked position, comes to rest pressing against a lid edge, wherein the locking and carrying handle 33 forms a further locking cam 19.1, wherein the further locking cam 19.1 engages in a lid recess in the locked position.

[0089] The attachable locking and carrying handles 33 are designed as a double plastic leaf spring element 34 in order to use the inherent tension of the plastic wall as a spring element.

[0090] The integrated spring tension in the locking and carrying handle 33, as a double plastic flat leaf spring 34 running across the entire handle width, compensates for height tolerances and presses the lid 2 with the sealing bead 6 onto the surrounding container rim 21 to seal the storage box 1.

[0091] The attachable locking and carrying handles 33 are received in receiving bores 35, which are arranged in ribs under the container rim 21, in order to be snapped into the receiving bores 35 via handle pins 36 and to close and keep closed the box system with holding spring pressure by means of a rotational movement from bottom to top.

[0092] Figure 13 shows a partial view in the area of ​​the attachable locking and carrying handles 33 of the storage box 1 according to the invention in the closed box state.

[0093] The locking position of the storage box 1 is achieved by a locking and carrying handle rotation 33 from bottom to top, so that the locking function engages via the integrated plastic flat leaf spring 34 and the system maintains the lid tension via the unfolded spring force and compensates for dimensional tolerances.

[0094] The plastic flat leaf spring 34, designed in a V-shape, extends over the entire width of the locking and carrying handle 33 to secure and facilitate the manual opening or closing of the storage box 1 via the attachable locking and carrying handles 33.

[0095] Figure 14 shows a 3-D main view of an embodiment of the storage box 1 according to the invention without lid 2 in the open state, but with attachable locking and carrying handles 33.

[0096] The locking and carrying handles 33 are movably mounted to the container 5 via mounting holes and handle pins, so that the locking rotation movement can be implemented manually without much effort and the plastic flat leaf spring 34 can fully unfold with its integrated tensile force.

[0097] Figure 15 shows a partial view in the area of ​​the attachable locking and carrying handles 33 of the storage box 1 according to the invention in the open box state.

[0098] The attachable locking and carrying handles 33 are rotatably fixed to the container 5 via a pin connection 35 / 36.

[0099] The V-shaped design of the double plastic flat leaf spring 34 extends across the entire handle width to maintain flexibility in conjunction with tensile strength and to guarantee a long-lasting function for the product.

[0100] Figures 16 and 17show a partial cross-section in the area of ​​the attachable locking and carrying handles 33 of the storage box 1 according to the invention, Figure 16 in the closed state and Figure 17 in the open box state.

[0101] The locking and carrying handle 33 is rotated via the handle shell 18, so that the double plastic flat leaf spring 34 expands briefly under spring tension when the locking cam 19 engages, in order to relax again after the locking cam 19 engages in the recess in the multi-surface lid cover rim 4 or, depending on the tolerance design, presses the lid 2 tightly onto the container 5 under tension.

[0102] The v-shaped double design of the double flat band spring 34 with the two flat leaf bands 37 enables a precise spring function in combination with the durability of this spring design.

[0103] In the installed v-shaped double flat band spring 34, both spring leg bands 37 are connected to each other via the V shape and the open V-side is attached to the movable locking and carrying handle 33, so that the spring function is distributed movably within the short, but over the entire locking and carrying handle width 33 and enables the system to have a secure spring and locking function.

[0104] By moving and stretching during the closing movement of the locking and carrying handle 33, the spring force in the spring leg bands 37 is activated to rotate and lock the locking and carrying handle 33 into the closed position and to hold the fixed closed position.

[0105] When the locking and carrying handle 33 is manually unlocked, the v-shaped double flat band spring is also briefly activated across the entire width of the handle in order to unlock the locking cams 19 and to allow the lid 2 to be removed from the container 5.

[0106] Figure 18 shows a top view into the container 5 of the storage box 1 according to the invention as an embodiment with storage space separation via pluggable partitions.

[0107] The waterproof partition pockets 38 and the waterproof grooves 39 in the container base 7 and in the container walls 8.1 and 8.2 accommodate the partitions with plug pins.

[0108] The waterproof receiving pockets in the container base 7 and in the two container walls 8.1 and 8.2 allow liquid goods to be stored or transported, with the lid 2 sealing the system from above with the sealing bead 6.

[0109] Figure 19shows a partial longitudinal section through the partition pockets 38 and grooves 39 of the embodiment of the storage box 1 according to the invention.

[0110] By inserting partition walls with plug-in pin geometry into the sealed partition wall pockets 38 in the container base 7 and into the sealed grooves 39 at the upper edge of the side wall 8.1 or 8.2, the stored goods are separated, or different goods can be stored and transported in the system in a watertight manner.
