Description

[0001] The invention relates to a container for storing products, an insert container of such a container, a container of such a container and a method for using containers, insert containers and lids to realize various containers.

[0002] Containers are used to store virtually any product, especially bulk goods, liquids, etc., and can also include chemical products or foodstuffs. Products stored in these containers are easy to transport because they are securely contained and the containers themselves are easy to move. Generally, after the product is removed, the containers and lids, usually made of plastic, are either cleaned and reused or recycled. However, cleaning the container can be complex or even impossible depending on the product, which contradicts the fundamental principle of resource conservation.

[0003] The present invention therefore aims to provide a container for storing products, components of the container and / or a method that, compared to conventional containers, enables resource conservation with regard to the material used, whereby the effort required to provide such a container should remain as low as possible and such a container or the product stored therein should be as easy to handle as possible.

[0004] The present invention solves this problem with a container for storing or transporting products with the features of claim 1. The container according to the invention comprises a container, an insert container for arrangement in the container, and a lid, wherein the container has a container base and a container side wall extending vertically away from the container base and forming a container opening at its upper end, wherein the container side wall includes a fastening section, in particular a circumferential one, in an upper end section, and wherein the insert container has an insert container base and an insert container side wall extending vertically away from the insert container base and forming an insert container opening at its upper end, wherein the insert container side wall includes a fastening section, in particular a circumferential one, in an upper end region.and wherein the lid has a lid base and a lid side wall surrounding the lid, which has a fastening section, in particular a circumferential one, wherein the fastening section of the container, the fastening section of the inner container, and the fastening section of the lid are designed and configured to interact in such a way that a closed operating situation can be realized in which the aforementioned components of the container are connected to one another in such a way that the opening of the container and / or the opening of the inner container is closed. The closed operating situation denotes a defined arrangement of the components of the container relative to one another. Accordingly, in the closed operating situation, containers,The inner container and lid are arranged relative to each other in a specific way. In the closed operating position, the container is in its intended closed operating state and can be placed with its underside on a horizontal, flat surface, with the container opening and the inner container opening each pointing vertically upwards and the lid forming the top of the container. In the closed operating position, the container's fastening section, the inner container's fastening section, and the lid's fastening section interact with each other.

[0005] For example, the mounting section of the insert container can have a first part with which it interacts with the mounting section of the container, and a second part with which it interacts with the mounting section of the lid, the first and second parts being vertically spaced apart from each other. In general, the first and second parts of the mounting section of the insert container can be configured as the first and second parts of a locking mechanism of the insert container; for example, these two parts of the locking mechanism can form independent locking sections of the locking mechanism. For example, the mounting section of the container can have a first part with which it interacts with the mounting section of the insert container, and a second part with which it interacts with the mounting section of the lid.For example, the lid's fastening section can have a first part with which it interacts with the container's fastening section, and a second part with which it interacts with the fastening section of the inner container. As explained for the inner container's fastening section, the first and second parts of a fastening section can generally, and preferably, be the first and second parts of a locking mechanism of the respective component of the container. In embodiments, the container can have further components, such as a carrying handle, a sealing lid, etc.

[0006] The container according to the invention is based on the idea of ​​providing an insert for the container to hold the respective product. This insert can be arranged inside the container and therefore does not need to possess the usual mechanical stability of a container of this type. Consequently, after use, the container according to the invention can generally be recycled because the container of the container of this type typically does not come into contact with the product. This avoids, where possible, the need for costly cleaning or preparation steps for reusing the container, or—in the case of products adhering to the container and not removable from it—disposal of the container after only one use.Preferably, the receiving volume of the insert container may be substantially equal to, slightly smaller than, or even larger than the receiving volume of the container, in particular at least 90%, in particular at least 95%, in particular at least 97%, in particular at least 100%, and / or less than 150%, in particular less than 130%, in particular less than 120% of the receiving volume of the container, wherein the insert container receives the product during use of the container according to the invention, so that contact of the product with the container bottom and / or the container side wall is prevented as far as possible. Advantageously, the fastening sections of the container, insert container and lid may be arranged in a predetermined vertical section of the container.The sections overlap to enable the described interaction of these sections to provide a closed operating position of the container, liner, and lid. In the closed operating position, the liner can be completely enclosed within the container or project vertically, i.e., upwards, beyond the container, preferably projecting less than 10% of the container's total vertical length. Preferably, in the closed operating position, the bottom of the liner is covered on its underside by the container bottom, so that the container can be placed on a flat horizontal surface with the underside of the container bottom in contact with it. Preferably, in the closed operating position, the bottom of the liner extends exclusively within the horizontal extent of the container bottom. Generally, the liner is preferably made of PET, in particular recycled PET (RPET).Preferably, the inner container, and especially the lid, is made of recycled plastic, particularly RPET. Manufacturing the inner container, and especially the lid, from recycled plastic allows the container to be designed in a particularly resource-efficient manner, since the very component of the container that is intended to be replaced after use is produced in a resource-efficient way. In some embodiments, the lid can have a film that forms an inner surface facing the bottom of the inner container when closed, and which can be detached from the rest of the lid. This allows the container to be designed in a particularly resource-efficient manner, since in some embodiments, only the film, and not the entire lid, needs to be replaced before refilling the container.Exchange refers to the use of a new component of an existing container to create a new container, while the remaining components of the existing container are reused to create the new container. In one embodiment, the container is made of RPET. In another embodiment, the container is made of a different material than the inner container.

[0007] Conventionally, the container base and / or the insert container base are essentially horizontal, while the container side wall and / or the insert container side wall extend essentially vertically. In principle, the mounting section of the container, the mounting section of the insert container, and / or the mounting section of the lid can be arranged at least partially circumferentially, and in particular completely circumferentially. The term "circumference" here refers to a horizontal circumferential arrangement around a vertical axis, for example, a central axis, which runs along a vertical direction and is associated with the container, the container, the insert container, and / or the lid. In the closed operating state of the container, a central axis of the container, a central axis of the insert container, or a central axis of the lid can be coaxial with each other. Generally, the container or insert container typically has a container base or...The container consists of a base and a side wall extending vertically from the base, forming an opening at its upper end. While the base extends essentially horizontally, the side wall extends essentially vertically. Both the base and side wall are plate-like, extending flat along their inner and outer surfaces. The thickness between these surfaces is defined by the shortest distance between the inner and outer surfaces.The base and side walls of the container together define the container's capacity. The side wall forms the container opening at its upper end, providing access to the container's capacity. The side wall encloses this opening with a rim that runs around it. Similarly, the side wall forms the container opening at its upper end, providing access to the container's capacity. The side wall encloses this opening with a rim that runs around it.

[0008] The basic shape of the container according to the invention, the basic shape of the container base, the basic shape of the insert container base, and / or the basic shape of the lid base can have a variety of configurations, for example, round, oval, polygonal, and in particular rectangular or square. As shown, the specified fastening sections of the container, the insert container, and the lid, which interact in the closed operating position, are arranged in an overlapping vertical section of the container in the closed operating position to fix or connect the aforementioned components to one another in order to close the opening of the container and / or the opening of the insert container. Advantageously, the container design according to the invention can be configured such that repeated adjustment and opening of the specified closed operating position is possible.

[0009] The insert container for use in a container according to the invention can, for example, be manufactured in one piece as a blow-molded part, in particular a blow-molded plastic part. Alternatively, it is also possible to assemble one or more separately manufactured plastic parts into such an insert container, for example by injection molding a circumferential mounting section that is connected to a plastic bag or a bag-like plastic sleeve, for example by welding or gluing. Generally, the mounting section of the insert container is advantageously designed to be dimensionally stable. "Dimensionally stable" means that the mounting section of the insert container does not fundamentally change its shape during intended use, with the exception of any interoperating locking mechanisms that may undergo elastic deformation when the closure of the container according to the invention is set and / or released.Preferably, a section of the insert container's side wall extending below the mounting section has less stability than the mounting section itself. Preferably, this section below the mounting section is not dimensionally stable. For example, this section of the insert container's side wall below the mounting section can be designed like a plastic bag. For example, in the manufacture of the insert container, a first section can be produced, forming the mounting section, and a second section can be produced, forming the section below the mounting section. These sections are then joined together to create the insert container.For example, a pouch-like section can be glued or welded to the section forming the fastening section to create the inner container, or it can be clamped to it or folded around it to create an inner container. The essential point is that, in the closed operating state, the inner container is positioned within the container of the assembly in such a way that it defines a receiving volume which is kept separate from the container.

[0010] In principle, and particularly in an embodiment where the inner container is bonded together by gluing or welding the circumferential mounting section to a bag-like residual container comprising the inner container base and a side wall extending vertically from it, it is possible for the bag-like section to be non-dimensionally stable, for example, designed as a foil bag. On the other hand, the container according to the invention can also have an inner container that is dimensionally stable in the area of ​​its mounting section as well as in the area of ​​the inner container base and / or the inner container side wall during intended use.This embodiment is particularly advantageous when the container of the inventive assembly has stacking ribs on its inner side, in the area of ​​the insert container's side wall, especially near the insert container's base. These ribs extend vertically upwards, particularly on the inner side, and facilitate unstacking of the containers by preventing nested containers from jamming. The described dimensional stability of the insert container prevents damage to the insert container if, in addition, the geometric dimensions of the insert container and the container are such that the insert container's side wall and the container's side wall are spaced apart from each other, particularly in the area of ​​the described stacking ribs.

[0011] Advantageously, the mounting section of the container, the mounting section of the inner container, and the mounting section of the lid may be designed and configured to provide, in the closed operating state, successive fixing areas of the mounting sections around a longitudinal axis, in particular a central axis of the container, each located over an associated circumferential section, which differ from one another with regard to the fastening of the container, inner container, and lid. This measure simplifies the design of the mounting sections and their interaction, since the respective coupling, fixing, and / or connection of the parts container, inner container, and lid can be distributed across angular sections of the mounting sections, so that, under certain circumstances, the overall volume of the mounting sections, in particular their respective transverse orThe vertical extent can be reduced. For example, it can be provided that in a first circumferential fixing section, one of the sub-containers, insert container, and lid is connected to one of the other two parts, and in a second circumferential fixing section, to the other part. Advantageously, these different circumferential fixing sections can be arranged consecutively, so that different components are connected to each other in the respective circumferential section, for example, by means of a snap-fit ​​connection.

[0012] Preferably, the mounting section of the insert container may have a locking device for engaging with a locking device associated with this locking device and encompassed by the mounting section of the container, and furthermore for engaging with a locking device associated with this locking device and encompassed by the mounting section of the lid, wherein, in the aforementioned closed operating state of the container, the locking device of the mounting section of the insert container is engaged with the associated locking device of the container, and the locking device of the mounting section of the insert container is engaged with the associated locking device of the mounting section of the lid. This is particularly relevant in embodiments where the mounting section of the insert container is arranged between the mounting section of the lid and the mounting section of the container.Since the container rests on these associated surfaces, a direct connection, in particular a direct locking mechanism between the lid and the container of the inventive assembly, can be dispensed with. The construction of the inventive assembly, in particular the construction of the interacting fastening sections of the inner container, the container, and the lid, can be simplified by designing the fastening section of the inner container to be rotationally symmetrical about a vertical axis of the container or the inner container. The rotational symmetry can be N-fold, such that the fastening section has N different fastening subsections that are rotationally symmetrical to each other over a defined angular range, or the rotational symmetry can be 360°, so that the rotational symmetry is given for every angle of rotation.In a generally preferred embodiment, the mounting section of the container and / or the mounting section of the lid can also be rotationally symmetrical about a vertical axis associated with the respective component. The vertical axis is preferably the vertical center axis of the respective component of the container. In the rotationally symmetrical embodiment of the mounting section of the inner container, it can have a mounting profile that is identical in longitudinal and vertical sections across its entire circumference.

[0013] To minimize the mechanical stress on the bottom and side wall of the container, it may be advantageous to provide that, in the closed operating situation, the bottom of the container is fully supported by the container base.

[0014] In one embodiment, the mounting section of the insert container has a transverse section extending outwards from the insert container's side wall, which, in the closed operating position, is supported by a transverse section of the container's mounting section that also extends outwards from the container's side wall. The transverse section of the insert container or container extends transversely, and thus perpendicular to the vertical direction, away from an adjacent section of the insert container's side wall or container's side wall, so that it projects transversely beyond this adjacent side wall section.

[0015] This ensures that, in the closed operating situation, the transverse sections of the container and the inner container can abut each other, with one of the transverse sections resting with its underside on the top side of the other transverse section. In general, this allows for vertical compression between the inner container and the container in the closed operating situation by providing further corresponding transverse sections of the container and inner container, offset vertically from the first transverse section, so that one of the inner container and container can be vertically compressed between the two transverse sections of the other inner container and container.In an embodiment where the transverse section of the insert container rests on the transverse section of the container from above during the closed operating state, this ensures particularly good support and retention of the insert container on the container. It should be noted that the mounting section of the insert container is preferably formed by a section of the container's side wall and / or is preferably formed by the insert container's side wall. Each of the mounting sections can preferably have at least one, and in particular several, vertically spaced transverse sections with the described properties.

[0016] In one embodiment, the side wall of the insert container has a thinner wall than the side wall of the container. In embodiments where the wall thickness varies across the extent of the respective side wall, a median wall thickness determined across the entire surface of the side wall is to be used for comparison. In one embodiment, the side wall of the insert container has a wall thickness of less than 1 mm, in particular less than 0.7 mm, in particular less than 0.6 mm, and in particular a maximum of 0.5 mm, over at least a predominant portion of its surface. In another embodiment, the side wall of the container has a wall thickness of more than 0.8 mm, in particular more than 0.9 mm, in particular at least 1 mm, and in particular less than 2 mm, in particular less than 1.8 mm, over at least a predominant portion of its surface.In one embodiment, the mounting section of the insert container has a wall thickness greater than the wall thickness of the insert container's side wall outside the mounting section and / or the insert container's base. The mounting section can be assigned a corresponding wall thickness as part of the side wall, defined analogously to the wall thickness of the rest of the side wall. More preferably, the mounting section of the insert container has a wall thickness that is at least 20%, in particular at least 40%, in particular at least 50%, in particular at least 100%, and / or less than 500%, in particular less than 400%, in particular less than 300%, in particular between 30% and 400%, preferably between 40% and 300% greater than the wall thickness of the insert container's side wall outside the mounting section and / or the insert container's base.

[0017] Preferably, the mounting section of the lid may have a circumferential groove for at least partial reception of the mounting section of the container and / or for at least partial reception of the mounting section of the inner container. In the longitudinal section of the container, the circumferential groove may be formed by a vertical rib extending upwards from a transverse edge section of the lid base in the installed position, to which a transverse rib is connected, and from which a downwardly extending, cantilevered vertical rib is connected. The design of the groove can ensure a particularly advantageous sealing connection between the lid and the inner container or container. Generally, preferably only a section of the mounting section of the inner container is received in the groove, so that the mounting section of the container is spaced apart from the groove.This allows the lid to be held particularly reliably to the insert container without over-determination, whereas, for example, the insert container can be connected to the container by means of its mounting section. Preferably, the mounting section of the insert container has a first part corresponding to the mounting section of the lid, which is particularly designed as part of a locking mechanism. This part of the mounting section of the insert container interacts with a part of the mounting section of the lid that is formed in the groove. Preferably, the mounting section of the lid is formed entirely within the groove. For example, the part of the mounting section formed in the groove can be...The fastening section formed in the groove may be designed as a projection provided in a groove wall or as a recess provided in the groove wall, wherein, for example, in the advantageous embodiment described above, the groove wall may be formed by one of the vertical webs of the cover. It is generally preferred that at least one of the groove walls or at least one of the vertical webs be spring-elastic, wherein the fastening section is formed at least partially on this groove wall or on this vertical web. It is generally preferred that the advantageously provided, self-supporting vertical web described above be spring-elastic. The spring-elastic design refers to the fact that the position of the vertical web or...The groove wall can be deflected spring-elastically along the transverse direction from a rest position, for example, to create and release a locking mechanism between corresponding fastening sections. The transverse direction is perpendicular to the vertical direction. When referring to the vertical center axis of the respective component, the transverse direction can be a radial direction with respect to the vertical center axis.

[0018] In one embodiment, the mounting section of the container has a transverse web to which a cantilevered vertical web is attached. In another embodiment, the insert container has a transverse web to which a cantilevered vertical web is attached. More preferably, the mounting section of the container is formed at least partially, and in particular at least predominantly, by the aforementioned vertical web of the container. More preferably, the locking mechanism of the container is formed at least partially, and in particular at least predominantly, by the vertical web. In one embodiment, the part of the mounting section of the insert container that interacts with the mounting section of the lid, and in particular the part of the locking mechanism of the insert container that interacts with the locking mechanism of the lid in the closed operating position, is formed at least partially by the vertical web.In one embodiment, the part of the mounting section of the inner container that interacts with the mounting section of the inner container, in particular the part of the locking mechanism of the inner container that interacts with the locking device of the inner container in the closed operating state, is at least partially formed by the vertical web. In another embodiment, in the closed operating state, the described vertical webs of the inner container and the inner container are vertically pressed together due to a latching interaction, wherein a vertical section of the vertical web of one inner container is pressed between two vertically spaced sections of the vertical web of the other inner container.In one embodiment, the vertical web of the insert container has a transverse offset, such that it comprises two vertical sub-webs separated from each other by the offset. A first sub-web, in particular the upper one, forms at least part of the locking mechanism of the insert container that interacts with the mounting section of the lid in the closed operating position, and a second sub-web, in particular the lower one, forms at least part of the mounting section of the insert container that interacts with the mounting section of the container in the closed operating position. Preferably, the transverse web or transverse section of the insert container extends transversely outwards, with the second sub-web extending from the outer end of the transverse web or transverse section.The transverse section extends upwards, with the insert container's side wall having a transverse outward offset at its upper end, and the first partial web extending vertically upwards adjoins this offset. Preferably, the respective vertical web of the container and / or the insert container forms at least part of the locking mechanism of the container or insert container and is transversely deflectable, so that the vertical web forms a transversely deflectable locking element of the respective mounting section. Advantageously, the transversely deflectable locking element of the container can have a transversely inwardly extending locking projection in an end section, particularly to provide a locking receptacle for the described locking mechanism of the mounting section of the insert container, which is preferably formed on a vertical web of the insert container.Preferably, it can be provided that this locking projection, or this locking element, forms an undercut with the locking device of the fastening section of the insert container to block a separation of the container and inner container in the vertical direction (longitudinal direction).

[0019] While in a first-type fixing area a connection, in particular a locking mechanism, is established between the container and the insert container, in a second-type fixing area a connection, in particular a locking mechanism, can be provided between the lid and the insert container. For this purpose, to define a second-type fixing area, the mounting section of the lid can, in a longitudinal section, have a self-supporting, vertically downward extending, transversely deflectable vertical section, which is designed as a locking arm of a locking element.In particular, the transversely deflectable locking element of the lid can have a transversely inwardly extending locking projection which, in the locked state, engages in a locking receptacle provided by the locking device of the insert container, such that the locking device of the insert container and the locking element of the lid form an undercut to block separation of the lid and inner container in the vertical direction (longitudinal direction).

[0020] Advantageously, in the closed operating situation of the container, within the fixing area of ​​the second type, the fastening section of the container can have a vertical web in a longitudinal section, which extends from a transverse web extending outwards from the container side wall, the transverse extent of which is smaller than the transverse extent of the transverse web of the fastening section of the container in the fixing area of ​​the first type, such that the vertical web is received transversely within the fastening section of the lid, so that this vertical web extends to a contact with a transverse web of the fastening area of ​​the inner container, which can in particular be designed as a locking arm of the locking device of the inner container, in order to provide mechanical support for the locking device of the inner container.This support can be particularly advantageous during the mutual locking process of the lid and container, where the mechanical support of the locking device of the insert container prevents deflection of its locking arm in the vertical direction. Preferably, the transverse extent of the transverse web of the container's fastening section within the second type of fixing area is less than 70%, but more than 10%, and in particular less than 50% and more than 20%, than the transverse extent of the transverse web of the container's fastening section in the first type of fixing area.

[0021] In advantageous embodiments, the transverse section extending outwards from the side wall of the insert container, which in the closed operating state is supported by a transverse section of the container's mounting section extending outwards from the side wall of the container, can preferably form or be identical to the transverse web of the insert container described above. More generally, the aforementioned transverse section of the container forms or is identical to the aforementioned transverse web of the container. In an advantageous embodiment, in the closed operating state, the locking device of the container engages a corresponding part of the locking device of the insert container, thereby ensuring that at least one vertical section of the mounting section of the insert container is vertically fixed in position between the transverse section and the mounting section of the insert container.The insert container is held in place by the transverse rib of the container and the locking mechanism of the container, and is pressed vertically between them. This ensures a particularly reliable fixation of the insert container relative to the main container.

[0022] In one embodiment, the container has several recesses through which the mounting section of the insert container is accessible from the outside when the container is closed. This recess allows a user to grasp the insert container from the outside when the container is closed. In this closed state, the portion of the insert container that extends within the recess is therefore not covered by the lid. Preferably, starting from the closed state, the insert container and lid can be removed together from the container by pulling the insert container and lid upwards out of the container, with the insert container and lid maintaining the same relative position to each other during removal as they did when the container was closed.A transverse projection, provided on the outer surface of the insert container and accessible through the recesses, is generally preferred. For example, the insert container can have two transverse projections, each associated with one of the recesses and positioned within their respective recesses during the closed operation. In one embodiment, the insert container has a transverse projection circumferentially around its vertical central axis, extending across both recesses during the closed operation and thus forming the respective transverse projection accessible from the outside through the respective recess. The transverse projection is generally preferred to be formed by a portion of the locking mechanism of the insert container.The transverse projection is generally preferably formed by the part of the locking device of the insert container that interacts with the locking device of the container in the closing operating situation, wherein in the closing operating situation it only interacts with the locking device of the container outside the recess, since the locking device of the container is interrupted at the level of the recesses.

[0023] In one embodiment, the mounting section of the insert container comprises, as vertically spaced, transversely extending sections, and in particular sections extending around a vertical central axis of the insert container, the transverse section of the insert container, a first part of the locking device corresponding to the locking device of the container, and a second part of the locking device corresponding to the locking device of the lid. The transverse section can be the second transverse web described above. The mounting section of the insert container thus preferably has at least three transversely extending sections, each in particular designed as a transverse projection. This ensures a particularly reliable attachment of the insert container both to the container and relative to the lid.Particularly preferably, the fastening section has a further transversely extending rib that is arranged vertically between the transverse section and the first part and / or the second part of the locking device. In embodiments in which the rib is provided, the fastening section of the insert container thus has at least four transversely extending and vertically spaced sections. By providing a rib between the transverse section and at least one part of the locking device, this rib can provide an additional functionality. For example, the rib can at least partially form the transverse projection that, in the closed operating position, is located within the recess of the container and is accessible from the outside.For example, the rib can provide transverse support for the insert container on the container between the transverse section and at least part of the locking device.For example, the mounting section of the insert container can be held vertically pressed against the container over a vertical section running between its transverse section and the first part of the locking device, by the transverse section resting on a corresponding transverse section of the container and the first part of the locking device of the insert container pressing against a corresponding locking device of the container, wherein the rib can be arranged between the transverse section and the first part of the locking device and, to prevent excessive deflection of the mounting section of the insert container relative to the container, can come into transverse contact with a corresponding section of an inner surface of the container side wall.

[0024] In one embodiment, the insert container is designed such that when several identically designed insert containers are stacked to form a stack, the upper of two adjacent insert containers in the stack rests with its additional rib on the upper side of one of the lower insert containers. Thus, in generally preferred embodiments of the container, the insert container is designed such that several identical insert containers can be stacked on top of each other, with each pair of insert containers in such a stack forming an adjacent, stacked pair along the stacking direction. Naturally, the upper insert container of this pair rests with its underside on the upper side of the lower one.By having the rib of the upper insert container rest on the top of the lower insert container, the rib can be specifically designed for easy stacking and unstacking. The vertical position of the rib is thus specifically aligned so that, when the insert containers are stacked, they are positioned vertically relative to each other, effectively preventing jamming within the stack. Preferably, the insert container side wall forms a step on its inner side at the vertical height of the rib, above which a transverse section of the upper insert container extends. Preferably, the transverse section of the upper insert container rests on this step within the stack. By having the step at the vertical height of the rib, i.e.,Since the insert container is essentially positioned at the same vertical location as the rib, its manufacture can be particularly simple. Furthermore, the offset allows the upper of the two adjacent insert containers to be positioned with its rib on top of the lower insert container in such a way that the outer side wall of its insert container does not jam against the inner side of the lower of the two adjacent insert containers, thanks to the offset.

[0025] In one embodiment, the mounting section of the insert container has a clear internal cross-section that decreases vertically from top to bottom. This can be particularly advantageous for stacking two insert containers without jamming, and also for stacking container assemblies, each comprising an insert container and a container, without jamming. Due to the decreasing clear internal cross-section from top to bottom, it is possible to form both stacks of insert containers and stacks of container assemblies in which the respective stackable units (insert container / container assembly) are stacked without jamming by adjusting the stacking height or...The immersion depth of two adjacent stacked units is varied, for example by the positioning of the described rib and / or the positioning of at least one of the described transverse sections of insert container / container at a suitable vertical position.

[0026] In one embodiment, both the container of the package is designed in such a way that it can be stacked with several identically designed containers to form a container stack, and the insert container of the package is designed in such a way that it can be stacked with several identically designed insert containers to form an insert container stack, and the lid of the package is designed in such a way that it can be stacked with several identically designed lids to form a lid stack.

[0027] Stackability includes the ability to form stacks with stackable units (insert container / lid / container / container arrangement) in which the two adjacent stacked units do not jam against each other, but rather interlock, so that they are stacked both vertically overlapping or interlocking and with transverse play. Furthermore, the container and the insert container of the assembly are particularly preferably designed such that a container arrangement consisting of the container and the insert container placed within it can be formed, and such a container arrangement can be stacked with several identically designed container arrangements.Generally, the respective stackable units are stackable in such a way that two adjacent units overlap by more than 50%, in particular more than 70%, of their vertical extension length when stacked on top of each other, and more preferably also have a transverse clearance of at least 0.5 mm, in particular at least 1 mm, in the stacked state, i.e. in the completed stack.

[0028] In one embodiment, during the closed operating state, the insert container and the container are arranged vertically relative to each other and together form a container assembly. This definition of a container assembly can generally apply to embodiments. Preferably, the insert container, with its mounting section, projects vertically around a vertical central axis of the container assembly beyond the container, in particular by at least 3 mm, and more specifically by at least 5 mm. Preferably, the insert container and the container are designed to correspond to each other such that when several identically designed container assemblies are stacked to form a container assembly stack, the underside of an upper container of two adjacent container assemblies in the stack rests on the upper side of the insert container of a lower of the two adjacent container assemblies.By having the insert container protrude vertically above the container in the container arrangement, and by ensuring that, in the stacked state, the underside of the container of the upper container arrangement rests on the top of the insert container of the lower container arrangement, a vertical arrangement of the container arrangements relative to each other can be specifically ensured, preventing jamming of two adjacent container arrangements in the container arrangement stack.At the same time, as explained, a stack of insert containers can be advantageously formed with the containers of the container, and a stack of containers can be advantageously formed with the containers as explained, so that the container of the container can be specifically designed for stacking on top of identically designed containers, the insert container can be designed for stacking on top of identically designed insert containers, and the advantageous container arrangement stacks explained above can also be realized through the targeted, mutually corresponding design of container and insert container.

[0029] In one embodiment, the upper of the two adjacent container assemblies in the container stack rests with a support section of its underside on the top of the insert container of the lower of the two adjacent container assemblies. The container is designed such that when several identically designed containers are stacked to form a container stack, the support section of the upper container of the two adjacent containers in the stack rests on the top of a lower of the two adjacent containers. The support section of the container thus serves both to rest on top of a lower container in a container stack and to rest on the insert container of a lower container assembly when the upper container assembly includes said container.Preferably, a horizontal clearance is ensured between an inner surface of the lower container and an outer surface of the upper container when two container arrangements are adjacent in the container stack, and also between an inner surface of the lower container and an outer surface of the upper container when two containers are adjacent in the container stack. Preferably, the horizontal clearance is at least 0.5 mm, more preferably at least 1 mm, and more preferably at least 1.5 mm.

[0030] In one embodiment, the container has a mass that is at least twice, and in particular at least three times, the mass of the inner container. Since the container can be used multiple times and only a new inner container, but not a completely new container, is required when refilling a container, a suitably advantageous ratio between the masses of the container and the inner container ensures that the highest possible mass fraction of the container can be reused, thus giving the container a particularly resource-saving effect.

[0031] In one embodiment, the container sidewall is free of ribs along its inner surface, and preferably, the container bottom is also free of ribs on its inner surface. By making the container sidewall and / or bottom free of ribs, the most uniform possible contact between the insert container and the inner surface of the container can be ensured. This allows the insert container to be optimally supported by the container, enabling the insert container to be designed with particularly thin walls or very low mass while avoiding adverse effects. More generally, the container is designed such that, when forming a stack of containers, two adjacent containers in the stack only rest against each other along the vertical direction in those sections that are located outside the inner surface of the container sidewall and base.

[0032] In one embodiment, the lid can only be locked to the insert container and thus not to the container itself. In another embodiment, the container, particularly within its mounting section, has a retaining device to which a carrying handle is attached. The carrying handle can be designed, in particular, in the form of a U-shape or a U-shaped bracket, as is common with containers. By providing the carrying handle on the container, the container can be carried easily and without damage using the handle, without the insert container needing to be robustly designed. By providing the retaining device within the mounting section, the retaining device can be easily and robustly designed within the container.

[0033] The invention further relates to an insert container of a container according to the invention. The insert container has features as can be seen from embodiments of the container according to the invention or as explained therein. The insert container is designed such that it can be inserted into the container of the container to realize the closed operating state of the container and, in the closed operating state of the container, is fixed in position relative to both the lid and the container by means of its fastening section.

[0034] The invention further relates to a container of a container according to the invention. The container has properties as can be seen from embodiments of a container according to the invention or as explained therein. The container is designed to correspond to the insert container such that the insert container of the container can be inserted into the container to realize the closed operating state of the container, wherein, in the closed operating state of the container, the container is fixed in position relative to both the lid and the insert container by means of its fastening section.

[0035] The invention further relates to a method for using a plurality of identically designed containers, a plurality of identically designed insert containers, and a plurality of identically designed lids. A specific container, a specific insert container, and a specific lid together form a container according to the invention. In the method according to the invention, after the container comprising the aforementioned specific components has been constructed and the specific insert container has been removed, another of the aforementioned insert containers is inserted into the specific container, and the other insert container is filled with a substance. The filled container arrangement formed by the specific container and the filled other insert container is then closed with the specific lid or another of the aforementioned lids.The method according to the invention thus makes a particularly advantageous contribution to resource conservation. In the method according to the invention, the same container can be used multiple times by successively producing different filled containers, each with the same container. First, a first container is formed with the container, a first insert container, and a first lid. The container, or rather the holding volume of the insert container, is filled with a substance, for example, paint. Then, the substance located in or stored in the insert container is used, and the first insert container is removed from the container. Finally, a second insert container is placed inside the container, and the holding volume of the second insert container is filled with a different substance.

[0036] The invention is explained in more detail below with reference to nine figures and exemplary embodiments.

Figure 3 comprehensive the Figure 3a, 3b , 3c and 3d Is container 1 according to Figure 1 in the Figure 1 The depicted closure operating situation is shown, but from different perspectives or sections. Figure 3a The entire container 1 is shown with a section along the vertical direction Z. Figure 3b The section is shown in a top view of container 1, which is in Figure 3a is depicted. In Figure 3a Two different zones are shown, namely zone K and zone L. Zone K of the in Figure 3a The cut shown is in 3D figure shown, the zone L of the in Figure 3a The cut shown is in Figure 3c depicted.

[0039] For the sake of simplicity, the following will be listed. Figure 1 , 2 and 3jointly explained. Container 2, insert container 4, and lid 6 are manufactured as separate parts independently of one another, which is generally advantageous. In the closed operating position, the lid 6 closes both the insert container opening of insert container 4 and the container opening of container 2. The lid base 60 horizontally covers the container opening and the insert container opening, and the lid side wall 61 forms a groove in which part of the mounting section 44 of insert container 4 is received. The lid base 60 extends horizontally, and the lid side wall 61 extends vertically away from the lid base 60. Similarly, the container base 20 extends horizontally, and the container side wall 21 extends vertically away from the container base 20. Similarly, the insert container base 40 extends horizontally, and the insert container side wall 41 extends vertically away from the insert container base 40.The container 2 has a mounting section 24, the insert container 4 has a mounting section 44, and the lid 6 has a mounting section 64. According to the invention, the mounting sections 24 and 44 of the container 2 and insert container 4 are advantageously located in an upper vertical end region of the container 2 and insert container 4, respectively, which extends from the upper end of the container 2 and insert container 4 over less than 30%, and in particular less than 20%, of the vertical length of the container 2 and insert container 4, respectively. The container 2 has a retaining device 23 on its outer surface, which corresponds to a retaining device 33 of the carrying handle 3, wherein the retaining device 23 and the retaining device 33 are interlocked in the closed operating position.They interlock along a transverse direction Y perpendicular to the vertical direction Z, as shown in . Figure 3cAs is evident, the retaining device 23 cannot be released from the retaining assembly 33 by a vertical relative movement of the two, but only by a transverse relative movement of the two. In contrast, the fastening sections 24, 44, 64 of container 2, insert container 4, and lid 6 are designed to correspond to each other such that the respective corresponding or cooperating fastening sections interlock along the vertical direction Z, allowing them to be released from each other by a relative movement along the vertical direction Z, starting from the illustrated closure operating situation. The fastening sections 24, 44, 64 each have locking devices 28, 48, 49, 69.The locking mechanism of the insert container 4 has a first part 48, which corresponds to the locking mechanism 28 of the container, and a second part 49, offset vertically upwards therefrom, which corresponds to the locking mechanism 69 of the lid 6. The insert container 4 also has a transverse section 47, which, in the closed operating position, rests on a transverse section 27 of the container 2. A vertical section of the mounting section 44 of the insert container 4 is vertically pressed between the locking mechanism 28 of the container 2 and the transverse section 27 of the container 2 in the closed operating position. In the illustrated embodiment, the transverse section 27 of the container 2 forms a transverse web of the container 2, to which a cantilevered vertical web of the container 2 is connected, forming the locking mechanism 28 of the container 2.The transverse section 47 of the insert container 4 forms a transverse web of the insert container, to which a cantilevered vertical web is attached, forming the locking device 48, 49, a projection 42, and a rib 43. In the closed operating position, the insert container 4 projects vertically beyond the container 2. In this projecting area, it forms the part 49 of the locking device, which interacts with the locking device 69 of the cover 6. As can be seen in particular from... Figure 6 in conjunction with the Figure 1 , 2 and 3As can be seen, the fastening section or locking device of the lid 6 is formed in a groove formed by the lid 6. This groove is formed by a vertical web 66 extending vertically upwards from the lid base 60, a transverse web 67 adjoining it, and a vertical web 68 extending vertically downwards from the transverse web 67, on the inside of which the locking device 69 or the fastening section is provided. The vertical web 66 forms a projection 65, with which it engages when a stack of lids is formed, as in Figure 6The mounting section 44 of the insert container 4 has, as vertically spaced sections, each designed as a transverse projection and in this case circumferentially around a vertical central axis of the insert container 4, the described transverse section 47 of the insert container 4, a first part 48 of the locking device of the insert container, which corresponds to the locking device 28 of the container 2, and a second part 49 of the locking device of the insert container, which corresponds to the locking device 69 of the cover 6, and a rib 43, which is arranged vertically above the transverse section 47 and vertically below both the first part 48 and the second part 49 of the locking device of the insert container 4. This rib 43 serves, on the one hand, for lateral ortransverse support of the insert container 4 on the container 2, but also the simplified stackability, as can be seen from . Figure 5 This is evident and explained in more detail below. Container 2 also has two recesses 22 through which, in the closed operating position, the mounting section 44 of the insert container 4 is accessible from the outside, as is evident, for example, from... 3D figure This is evident. Within these recesses 22, the first part 48 of the locking device of the insert container 4 runs. The recesses 22 are opposite each other along a horizontal direction. In the Figures 1 and 2a Only one of the recesses 22 is shown in each case; the other is located exactly opposite this recess 22 on the other side of the container side wall 21. From the overall view of the Figures 1, 2a and 3dIt is evident that, starting from the depicted closure operating situation, the insert container 4 can be easily grasped through the recess 22, whereby the transverse projection or the part of the locking device 48 forms a vertical point of application, so that a vertical relative force can be easily applied to the insert container relative to the container 2, enabling it to be detached from and removed from the container 2, or enabling the first part of the locking device 48 of the insert container 4 to be detached from the locking device 28 of the container 2. The lid 6 can remain locked to the insert container 4 unchanged and thus keep the insert container opening closed.

[0040] In the Figures 4 , 5 , 6, 7 and 8Various schematic diagrams depict sections of different stacks, each stack being formed by stacking identical units on top of each other, with the units of the different stacks differing from one another. Figure 4 Containers 2, identical in design as units, are stacked on top of each other to form a container stack. Figure 5 comprehensive the Figures 5a and 5b Two different stacks are shown, each of which is formed by identically designed insert containers 4 as units, such that one insert container stack is formed in each case, the insert containers 4 of the stack being arranged according to Figure 5a differ from the insert containers 4 of the stack according to 5b. In Figure 6 A stack is shown which has identically designed lids 6 stacked on top of each other, so that a lid stack is formed. Figure 7A stack of identically formed containers 1 is formed as stacked units of the stack. In Figure 8 A stack is shown, comprising identical container arrangements stacked on top of each other, each container arrangement comprising a container 2 and an insert container 4. The containers 2 of the container stack according to Figure 4 , the deployment containers 4 of the deployment container stack according to Figure 5a , the lids 6 of the lid stack according to Figure 6 , the containers 1 of the container stack according to Figure 7 and the container arrangements of the container arrangement stack according to Figure 8 are shown analogously to the components of an embodiment of a container 1, which are related to the Figures 1 to 3 This is explained. The insert containers 4 of the stack according to Figure 5b They do, however, have the same fastening section 44 as the insert containers 4 of the stack according to Figure 5a on, but in the embodiment according to Figure 5a The respective insert container 4 is manufactured by means of an injection molding process using an injection mold that defines its geometric shape, whereas the insert containers 4 according to Figure 5b are manufactured using injection blow molding, so that the side wall 41 of the respective insert container 4 is in accordance with Figure 5b outside the fastening section 44 of the insert container 4, the wall thickness is significantly less than the insert container wall 41 of the insert container 4 according to Figure 5a outside the fastening section 44 of the deployment container 4 according to Figure 5aIn an injection blow molding process, a raw form is first manufactured using an injection molding process, the geometric shape of which is defined by the injection molding tool used during the injection molding process, after which the hollow body is blown from the raw form, which is formed by the finished insert container 4.Preferably, an insert container 4 can be produced by first producing the mounting section 44 of the insert container 4 by injection molding and then producing the insert container 4 by processing the previously produced mounting section 44, by arranging the predominant part of the insert container side wall 41 of the insert container 4 on the mounting section 44, for example as explained by injection blow molding or as explained by attaching a previously separately produced bag to the mounting section 44, for example by gluing, welding or clamping.In these generally advantageous embodiments, in which the side wall of the insert container 41 can be designed with a very thin wall thickness for a predominant proportion, a dimensionally stable fastening section 44 is always provided, so that the insert containers 4 can be stacked to create an insert container stack, as exemplified in . Figure 5b shown.

[0041] From the overall view of Figures 4 , 5 , 6 and 8It is evident that the various components of the container 1 of the illustrated embodiment can each be advantageously stacked inside one another, so that in the stacked state they overlap with a predominant proportion of their vertical extent length, in particular at least 50%, and in particular at least 70%, and preferably over 80% in the case of a container stack, insert container stack, or container arrangement stack. In the case of an insert container stack comprising insert containers 4 with a relevant non-dimensionally stable portion of the insert container side wall 41, the reference is to the maximum vertical extent length of the respective insert container 4, which it has when it is connected to the container 2 of the container 1 to form a container.by means of a fastening section 44, wherein the insert container 4 always assumes its maximum vertical extension length when the container 1 is in the described closed operating state and is filled with a liquid, for example water, which occupies at least 70% of the intake volume of the insert container 4 that it has in the closed operating state of the container 1 or in the closed operating situation.

[0042] Out of Figure 4It is evident that when the containers 2 are stacked on top of each other to form a container stack, the upper of two adjacent containers 2 in the stacked state rests with the underside of its transverse section 27 on the top of the lower container 2, wherein, in particular – as exemplified in the present embodiment – ​​the top of the lower container 2 is formed by a vertical web, which is designed as a self-supporting vertical section provided on the transverse section 27 of the lower container, the transverse section 27 forming a transverse web of the container 2. Naturally, in a container stack according to Figure 4The opening 25 of the uppermost container 2 of the container stack is arranged facing upwards. The uppermost container 2 of the container stack can be easily removed vertically upwards from the rest of the stack, since the container side walls 21 of two adjacent containers 2 of the container stack are not jammed together, but are arranged with minimal transverse play relative to each other in the stack by the support of the transverse section 27 of the upper container 2 on the top of the lower container 2.

[0043] Out of Figure 5aIt is evident that when identically designed insert containers 4 are stacked on top of each other, the upper of two adjacent insert containers 4 in the stacked state generally has a rib 43 on its underside. This rib is arranged, with respect to the vertical direction Z, between the part 49 of the locking device corresponding to the lid 6 and the transverse section 47 of the insert container 4, and with respect to the vertical direction between the part 48 of the locking device of the insert container 4 corresponding to the container 2 and the transverse section 47 of the insert container 4. Furthermore, it is evident that the insert container wall 41 forms a projection 42 on its inner side at the level of the rib 43, above which the transverse section 47 of the upper of the two adjacent insert containers 4 extends.This also makes it possible to create a stack of insert containers 4 when stacking them on top of each other, in which the insert containers 4 that are adjacent to each other in the stack are arranged with a small transverse clearance relative to each other, so that they are arranged without jamming, allowing the uppermost insert container 4 of the stack to be easily removed vertically upwards from the rest of the stack. Naturally, the opening 45 of the uppermost insert container 4 of the stack points vertically upwards.

[0044] Out of Figure 6It is evident that in the formed stack of lids, the upper of two adjacent lids 6 in the stacked state is supported by a projection 65 of a vertical web 66 on a transverse web 67 of the lower lid 6, which forms a section of the top of the lower lid 6, wherein starting from the projection 65 the vertical web 66 extends upwards, then a transverse web 67 extends cantilevered to the side and then from this transverse web 67 another vertical web extends cantilevered downwards, so that a groove is formed by the two vertical webs 66, 68 and the transverse web 67 connecting them, which forms the locking device 69 of the lid 6 on its outer groove wall, which is formed by the vertical web 68.By forming the locking device 69 on the outermost vertical web 68, it is generally advantageous to connect the locking device 69 to the cover base 60 in a transversely spring-like manner, whereby the vertical web 68 is spring-like and deflectable relative to the cover base 60 in a transverse direction. Figure 6 It is also evident that in the stack of lids the lids 6 are supported on each other by a transverse play and thus held together, whereby the topmost lid 6 in the stack of lids can easily be removed vertically upwards from the rest of the stack.

[0045] Out of Figure 8It is evident that in a stack of containers, the container 2 of the upper of two adjacent container arrangements, when stacked, rests with the underside of its transverse section 27 on the upper side of the insert container 4 of the lower container arrangement. This is advantageously enabled by the fact that the insert container 4 of each insert container arrangement projects vertically beyond the container 2. Each container arrangement is formed by an insert container 4 and a container 2, which are interlocked by their locking devices 28, 48 and thus fixed to one another. From the overall view of the Figures 4, 5a and 8It is evident that container 2 and insert container 4 are specifically designed to be compatible with each other, such that several identical containers, several identical insert containers, and several identical container arrangements can be stacked. Preferably, the vertical distance between the tops of two adjacent containers 2 in a container stack is less than the vertical distance between the tops of two containers 2 contained in two adjacent container arrangements within a container arrangement stack. This, along with the conical design of the insert container side wall 41 and the container side wall 21, advantageously ensures jam-free stacking of both containers 2 and insert containers 4, as well as container arrangements formed by insert containers 4 and containers 2.

[0046] Out of Figure 7It is further evident that in the advantageous embodiment, several containers 1 can be stacked on top of each other to form a container stack, with each container 1 having its closed operating state. In such a container stack, the upper of two adjacent containers 1 in the stack rests with the underside of the container base 20 of its container 2 on the top of the lid base 60 of the lid 6 of the lower container 1.
