Abstract
Description
[0001] The invention relates to a container for storing or transporting products, comprising at least a container and a lid for closing the container.
[0002] Containers of this type are used for storing or transporting virtually any product, especially bulk goods, liquids, etc., and can also include chemical products or foodstuffs. Generally, after the product is removed from the container, the containers and lids, which are usually made of plastic, are either cleaned and reused or subjected to a recycling process. However, cleaning the container can be complex or even impossible depending on the product, which contradicts the fundamental principle of resource conservation.
[0003] Therefore, the present invention aims to provide a container for storing or transporting products that, compared to conventional containers, allows for resource conservation with regard to the material used without significantly increasing the effort required to provide such a container.
[0004] The present invention solves this problem with a container for storing or transporting products having 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 insert container and the fastening section of the lid are designed and configured to interact in such a way as to connect the said parts of the container to each other in a closed operating position, such that the opening of the container and / or the opening of the insert container is closed.
[0005] 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. This allows the container to be reused after use without complex cleaning or preparation steps, as the container does not typically come into contact with the product. For this purpose, the insert can have a volume that is essentially equal to or slightly smaller than the volume of the container itself. During use, the insert holds the product, thus preventing contact between the product and the bottom and / or side walls of the container.Advantageously, the fastening sections of the container, insert container and lid can be arranged in a predetermined vertical section of the container or overlap in order to enable the described interaction of these sections to provide a closed operating position of the container, insert container and lid.
[0006] Conventionally, the container base and / or the inner container base are essentially horizontal, while the container side wall and / or the inner container side wall extend essentially vertically. In principle, the mounting section of the container, the mounting section of the inner 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 path around a vertical axis, for example, a central axis, which runs along a vertical direction and is associated with the container, the container, the inner container, and / or the lid. In the closed operating state of the container, the central axis of the container, the central axis of the inner container, and / or the central axis of the lid can be coaxial with each other.
[0007] 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 are arranged in an overlapping vertical section of the container in the closed operating position for fixing or connecting the aforementioned parts 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.
[0008] Further developments of the invention as well as additional features according to the invention are specified in the following general description, the figures, the figure description and the dependent claims.
[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. Advantageously, the area of the mounting section of the insert container is 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.
[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 position, 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 fastening section of the insert container may have a locking device for locking with a locking device associated with this locking device and arranged on the fastening section of the container, and furthermore for locking with a locking device associated with this locking device and arranged on the fastening section of the lid, wherein in the said closed operating situation of the container the locking device of the fastening section of the insert container is locked with the associated locking device of the container and the locking device of the fastening section of the insert container is locked with the associated locking device of the fastening section of the lid.Advantageously, in this embodiment, for example, the locking device of the mounting section of the insert container may have a single locking element and, in a first fixing section, interact with a complementary locking element of the lid to lock it to the lid, and, in a wide circumferential fixing section, interact with a locking element of the container to lock the insert container and the container. Again, the different circumferential fixing sections may be designed to be continuous, particularly such that an alternating locking mechanism of the insert container and lid, and of the insert container and the container, is formed over the entire circumference of the fixing sections. This is particularly advantageous 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 is attached to the associated plant surfaces, a direct connection, in particular a direct locking mechanism between the lid and the container of the container according to the invention, can be dispensed with.
[0013] The construction of the container according to the invention, in particular the construction of the interacting fastening sections of the insert container, container and lid, can be simplified by designing the fastening section of the insert container to be rotationally symmetrical about a longitudinal axis of the container or the insert container. In this embodiment, the fastening profile of the insert container is therefore identical in longitudinal and vertical sections over its entire circumference.
[0014] In order to provide a connection or fixation of the insert container, container, and lid to each other over the entire circumference when multiple different, successive fixing sections are present, the respective circumferential extent of these fixing sections can be limited to a predetermined dimension by the fact that the fixing section of the container and the fixing section of the lid have N-fold rotational symmetry about a longitudinal axis of the container, where N is a natural number, in particular > 1 and < 40. In particular, N can be > 1 and < 21, preferably > 1 and < 9, for example N = 4, 6, or 8.
[0015] To minimize the mechanical stress on the base and side wall of the container, it may be advantageous to provide that, in the closed operating position, the base of the container is fully supported by the container base. Furthermore, it may be advantageous to provide that the mounting section of the container has a mounting flange extending transversely outwards from the side wall of the container, which, in the closed operating position, is supported by a mounting flange of the container's mounting section that also extends transversely outwards from the side wall. It may therefore be advantageous to provide that an underside of the mounting flange of the container rests against an upper side of the mounting flange of the container.
[0016] To ensure a proper connection between the liner, container, and lid in the closed operating state of the container according to the invention, it may be advantageously provided that the wall thicknesses in the area of the mounting section of the liner are greater than in the area of the liner side wall and / or the liner base. Such a wall thickness can refer to the shortest connection between the inside and outside of a wall. Advantageously, it may be provided that the thickness of the liner in the area of its mounting section, i.e., the thickness of the walls in the area of the mounting section, is at least 20% greater and less than 500%, in particular > 30% and < 400%, preferably > 40% and < 300%, compared to the wall thicknesses in the liner side wall and the liner base.
[0017] To close the opening of the insert container, it may be advantageous to provide that the lid base has a circumferential vertical rib on a transverse edge section, which, in the closed operating position of the container, extends vertically downwards towards the top of the insert container's mounting flange. Advantageously, this mounting flange can, in longitudinal or vertical section, abut a vertical rib of the insert container's mounting section, which extends from the transverse mounting flange of the insert container.
[0018] 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. The circumferential groove in the longitudinal section of the container may be formed by a web extending upwards from a transverse edge section of the lid base in the installed position, to which a transverse web is connected, from which a downwardly extending, self-supporting vertical web is connected.
[0019] To stabilize the circumferential groove of the lid's fastening section, it may be advantageous to provide that the fastening section of the insert container extends in a longitudinal section of the container in its closed operating position with a vertical section up to an underside of a transverse section of the lid's fastening section that vertically closes off the lid's fastening section.
[0020] To support the coupled fastening sections in the closed operating situation of the container, it may be advantageous to provide that the fastening section of the container, in a longitudinal section, includes a transverse web extending outwards from the side wall of the container, to which a self-supporting vertical web is attached to support an associated web of the fastening section of the inner container or an associated web of the fastening section of the lid.
[0021] To provide a simplified design for the mounting sections, it is advantageous to provide that the mounting section of the insert container, in a longitudinal section, has a transverse section extending from a vertical section, which is cantilevered at its transverse end and designed as a locking device. Preferably, the locking device can be configured and designed to provide a snap-fit connection with the container by having an associated locking device on the mounting section of the insert container for interaction with the locking device on the mounting section of the insert container. Furthermore, the locking device on the mounting section of the insert container can be configured and designed to provide a snap-fit connection with the lid by providing an associated locking device within the mounting section of the lid.
[0022] To define a first circumferential section in which the container is connected to the insert container, and in particular locked in place, it may be advantageously provided that, in at least one first circumferential section, the mounting section of the container has a transversely deflectable locking element in the form of a vertical web extending from a transverse flange extending outwards from the side wall of the container, thus defining a first-type fixing area. Advantageously, the transversely deflectable locking element of the container may have a transversely inwardly extending locking projection in an end section, in particular to provide a locking groove for the described locking device of the mounting section 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).
[0023] To provide a closed appearance of the fastening sections of the container, insert container and lid connected as described within the fixing area of the first type, it may be advantageously provided that, in the closed operating situation of the container according to the invention, a free-supporting vertical section of the fastening section of the lid is vertically aligned with the locking element of the container within the fixing area of the first type and extends towards it, in particular until contact is made.
[0024] While in the first type of fixing area a connection, in particular a locking mechanism, is established between the container and the insert container, in a second type of fixing area a connection, in particular a locking mechanism, can be provided between the lid and the insert container. For this purpose, in at least a second circumferential section to define a second type of fixing area, the mounting section of the lid can have, in a longitudinal section, 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 groove 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).
[0025] 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 flange extending transversely outwards from the container side wall, the transverse extent of which is smaller than the transverse extent of the transverse flange 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 area 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 flange of the container's mounting 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 flange of the container's mounting section in the first type of fixing area.
[0026] Advantageously, in the closed operating state of the container according to the invention, a multiple sequence of the first-type fixing area and the second-type fixing area is formed over the entire circumference of the interconnected fastening sections of the container, insert container, and lid, in particular such that a continuous sequence of these fixing areas is formed over the entire circumference. In another embodiment, it can also be provided that this sequence of continuously successive fixing areas comprises more than two, for example, three different fixing areas.
[0027] The invention further relates to a container, an insert container and a lid for designing the container according to the invention.
[0028] The invention is explained below by describing one embodiment together with variations, with reference to the accompanying drawings, wherein Fig. 1 a container according to the invention in a side view, Fig. 2 the container according to the invention Fig. 1 in an exploded view, Fig. 3 a container for the container according to the invention Fig. 1 in a frontal view, Fig. 4 a sectional view of the container in the Fig. 3 specified cutting plane DD, Fig. 5 in a frontal view, an attachment container of the container according to the invention.

[0029] Fig. Figure 1 shows a container 1 according to the invention for storing and transporting products such as bulk goods or flowable materials in a side view, wherein Fig. Figure 2 shows an exploded view of the container 1, which comprises the components container 2, insert container 4 (designed to fit inside container 2), and lid 6 (designed for repeatedly opening and closing container 1). In the described embodiment, both container 2 and the insert container 4 have a circular base with slightly conical side walls. Container 2 and insert container 4 each have a fastening section 24, 44 at their respective upper end regions. Furthermore, lid 6 has a side wall that includes a corresponding fastening section 64. The aforementioned fastening sections 24, 44, 64 are designed and configured to detachably connect container 2, insert container 4, and lid 6 to one another and to close the opening of container 2 and / or insert container 4.For this purpose, fastening sections 24, 44, and 64 feature engagement designs for connecting these components to one another. As shown in... Fig. As can be seen in Figure 2, the fastening sections 24, 64 of the container 2 and the lid 6 do not have rotational symmetry about a longitudinal axis of the container 1, which here coincides with the longitudinal axes of container 2, insert container 4 and lid 6, but rather have widely spaced designs that differ from each other, so that widely spaced fixing sections can be provided by the cooperating fastening sections in order to enable a secure fastening of the components to each other and a secure closing of the container 1, without having to increase the overall height of the fastening sections 24, 44 64 compared to a conventional container such as a bucket and a lid.
[0030] Fig. Figure 3 shows the container 2 of the container 1 according to the invention in a frontal view looking at the container bottom 20 through the opening 25. The circumferential mounting section 24 of the container 2 is visible, segmented into two differently shaped mounting subsections 24a, b, which are arranged alternately around the circumference of the upper end region of the container 2. In the described embodiment, these mounting subsections have different circumferences; in a further embodiment, the mounting subsections can also have identical circumferences.
[0031] Fig. 4 shows the container 2 according to the invention in the Fig. Section DD shown in section 3. The bucket 2 has a circular container base 20, from which a container side wall extends vertically away, forming the container opening 20 at its upper end.
[0032] Depending on the embodiment, the container 2 or bucket according to the invention can be manufactured, for example, by injection molding or injection compression molding. The average sidewall thickness and / or bottomwall thickness can generally be > 0.60 mm, in particular > 0.80 mm, depending on the product to be contained, with the thickness typically being < 2 mm.
[0033] In the described embodiment, all parts of the container 1, i.e., container 2, insert container 4, and lid 6, are stackable, which significantly simplifies handling. For unstacking the containers, they have stacking ribs 26 extending vertically from the bottom upwards along a section of the container side wall 21. These ribs are spaced apart from each other around their circumference, so that the arrangement of the stacking ribs 26 prevents jamming of nested containers 2, since an inserted container cannot be inserted far enough to cause jamming.
[0034] Fig. Figure 5 shows the insert container 4 according to the invention for the design of the container 1 according to the invention in a frontal view looking at the insert container base 40 through the insert container opening 45. In contrast to the fastening section 24 of the container 2, the fastening section 44 of the insert container 4 is formed uniformly around its entire circumference, so that there is no circumferential segmentation, which simplifies the assembly and connection of container 2 and insert container 4.
[0035] In the described embodiment, the insert container 4 is designed as an injection mold, wherein not only wall sections and webs within the mounting section 44 are dimensionally stable, but also the insert container side wall 41 and the insert container base 40. However, it is also within the scope of the invention to manufacture the mounting section 44 separately from the wall sections receiving the product, such as the insert container side wall 41 and the insert container base 40, and subsequently to connect them, in particular by means of a material bond, for example by welding or gluing. In this embodiment, the volume intake can be provided, for example, by a film bag, which can have a wall thickness that is significantly less than the base and / or the side wall of the container 2.For example, the insert container 4 can be designed such that the insert container side wall 41 and / or the insert container base 40 have a thickness between approximately 50 µm and 250 µm. In this embodiment, the base and side wall of the insert container are not dimensionally stable, but are advantageous with regard to the described resource conservation.
[0036] Fig. Figure 7 shows a frontal view of the lid 6 of the container 1 according to the invention; Figure 7 shows a section through the container 1. Fig. Section FF shown in Figure 7. The lid 6 has a lid base 60 and a lid side wall 61 surrounding the lid, which includes a fastening section 64 of the lid 6 for interacting with the fastening sections 24, 44 of the container 2 and the insert container 4. In the present embodiment, this fastening section extends substantially over the entire vertical extent of the lid side wall; i.e., fastening section 64 of the lid 6 and lid side wall 61 hereinafter refer to the same section of the lid 6. As can be seen in the sectional view of the lid 6 of the Fig. 8 is the fastening section 64 of the cover 6 not as Fig. 7 suggests that it is not single-profile, but like container 2, it has different fastening sections extending over a predefined circumferential section, the designs of which are different and which correspond extensively to the fastening subsections of the container to provide a fixing area extending over a predefined circumferential section, which results from the interaction of the fastening sections of container 2, insert container 4 and lid 6.
[0037] Fig. Figure 9 shows an enlarged view of detail K of the Fig. 4, i.e., a perspective view of the mounting section 24 of the container 2. The mounting section 24 of the container 2 has in the mounting subsection 24a a locking device 27 in the form of a locking element, which has a transversely deflectable locking arm 27a and at its end section a locking projection 27b that extends transversely inwards. As a comparison with Fig. As shown in Figure 3, the locking device 27 is located within the extensive section of a fastening subsection 24a. The further construction of the fastening section 24 of the container 2 is explained below with reference to the interaction of the fastening sections 24, 44 and 64 of container 2, insert container 4 and lid 6.
[0038] Fig. Figure 10 shows a perspective view of an enlarged detail L of the fastening section 44 of the insert container 4 of the Fig. 6. As explained above, in the described embodiment, the fastening section 44 of the insert container 4 is rotationally symmetrical about a central or longitudinal axis of the container 1 and thus of the container 2 and the insert container 4, i.e., the Fig. The profile specified in section 10 is unchanged over the entire circumference of the fastening section 44, see Fig. 5. As from Fig. As can be seen in Figure 10, an outwardly extending transverse section 46 in the form of a circumferential flange adjoins the essentially vertically extending side wall 41 of the insert container. This transverse section transitions into a vertical section 47, to which, optionally after the provision of a further transverse section, a cantilevered vertical section 49 is attached. Approximately in the vertical center of the mounting section of the insert container 4, a locking device 48 in the form of a locking flange extends from the cantilevered vertical section 49. This locking flange comprises a locking arm flange 48a and a vertically upwardly pointing locking projection 48b.
[0039] It should be noted that the sections and flanges described above, in particular transverse and vertical sections and flanges, appear as webs in a frontal sectional view and thus, in the present application, essentially denote the same features as webs. This applies to the design of the container 2, the design of the insert container 4, as well as to the design of the lid 6 of the container 1 according to the invention.
[0040] Fig. Figure 11 shows an enlarged view of detail J of the Fig. 8, i.e., one of the two fastening subsections of the fastening section 64 of the cover 6. In the installed position, a vertical section 66 extends from the cover base 60, to which a transverse section 67 is attached, which transitions into a self-supporting vertical section 68 to form a groove 70. In the Fig. In the fastening subsection 64b shown in 11, the vertical section 68 is extended downwards for a longer period than in the fastening subsection 64a not shown, wherein a locking projection is formed on the inside of the vertical section to provide a locking device 69, in which the vertical section 68 acts as a locking arm section.
[0041] Fig. Figure 12 shows a frontal view of the container 1 according to the invention, in which the individual parts container 2, insert container 4 and lid 6 are joined together and the closure operating situation is set. Fig. 13 shows a cut in the Fig. 12 specified sectioning plane AA, wherein this sectioning plane is positioned such that the in Fig. The 13 marked detail sections G, A are located in different fastening subsections of container 2 and lid 6, respectively. As explained, container 2 has stacking ribs 26 on the inside of its container side wall 21. According to the invention, in the described embodiment, it can be provided that in the area of the upper ends of container 2 and insert container 4, the insert container 4 abuts the inside of the container side wall 21 with the outside of its insert container side wall 41.these do not touch and the dimensions of the insert container 4 relative to the container 2 are designed such that the distance between the side walls increases continuously up to the bottom section, in particular such that in the area of the stacking ribs 26 the spacing of these ribs to the outside of the insert container side wall 41 is at least twice, but less than ten times, in particular at least four times, but at most eight times the thickness of the insert container side wall 41 in this section.
[0042] The Fig. Figures 14a and 14b show the interaction of the fastening sections 24, 44, 64 of the container 2, the insert container 4 and the lid 6 in a first fixing area extending over a predetermined circumferential section of the fastening sections 24, 44, 64, in which the container 2 is locked to the insert container 4. Fig. Figure 14a shows a perspective view corresponding to detail G of the Fig. 13, while Fig. Figure 14b shows this design in a frontal sectional view. The mounting section 44 of the insert container 4 has a mounting flange 46 (transverse section) extending transversely outwards from the insert container side wall 41, which is supported by a mounting flange 28 (transverse flange) of the mounting section 24 of the container 2, which also extends transversely outwards from the container side wall 21. The lid base 60 has a circumferential vertical rib on a transverse edge section, which extends vertically downwards to contact the upper surface of the mounting flange 46 (transverse flange) of the insert container 4 in order to close the opening of the insert container 4.The fastening section 64 of the lid 6 has a circumferential groove 70 for at least partially receiving the fastening section 44 of the insert container 4, in this case the cantilevered vertical section 49, which extends to the underside of a transverse section 67 that closes off the fastening section 64 of the lid 6. The container 2 and insert container 4 are locked together in the groove 70. Fig. The first-type fixing area shown in 14a, b is achieved by a transversely deflectable locking element 27 interacting with the locking device 48 of the insert container 4 by providing an undercut between the two locking projections, thereby enabling the locking mechanism in the Fig. The relative position of container 2 and insert container 4 shown in 14a, b is fixed.
[0043] The Fig. Figures 15a and 15b show the design of the fastening sections 24, 44, and 64 in a second type of fixing area, in which the connection between the cover 6 and the insert container 4 is achieved by snapping. This represents Fig. 15a an enlarged view of the perspective detail H of the Fig. 13 ready, while Fig. Figure 15a shows a frontal sectional view of the second type of fixing area of the fastening sections of the container, the insert container 4 and the lid 6. The following description focuses in particular on the differences compared to the design of the second type of fixing area according to the Fig. 14a, b received. The transverse section 28' adjoining the container side wall 21 is recognizable in comparison to the situation of the Fig. 14a,b is shortened so that the adjoining vertical section 29 extends to the underside of the locking device 48 of the insert container 4. Furthermore, the outer vertical section 68 is extended to form the groove 70 on the fastening section 64b and forms a locking device 69 at its cantilevered end, which interacts with the locking device 48 of the insert container 4 to lock the insert container 4 and the lid 6, in particular such that a locking projection of the locking device 69 engages in a groove formed by the locking device 48.
[0044] In the described embodiment, the circumferential extents of the two fixing areas of the first and second type differ, with a four-fold sequence of fixing areas of the first type and fixing areas of the second type being formed over the entire circumference of the fastening sections 24, 44, 64 by means of correspondingly designed fastening sub-sections on the container and the lid. It is within the scope of the invention to provide a larger number of these sequences, e.g., six, eight, or ten.
[0045] Fig. Figure 16 shows the arrangement of the coupled fastening sections according to the Fig. 14a, b a relative alignment of the insert container 4 to the container 2 as the initial situation for locking the two parts together by applying a vertical force to deflect the locking device 27 of the container 2 transversely outwards, so that as in the Fig. As shown in 14a, b, the locking device 48 is arranged below the locking projection of the locking device 27 and the mounting flanges 28, 46 of the container 2 or the insert container 4 come into contact.
[0046] Fig. Figure 17 shows an embodiment of the fastening sections 24, 44, 64 of container 2, insert container 4 and lid 6 according to the Fig. 15, b a relative arrangement in which the insert container 4 with the mounting flange 46 rests against an associated mounting flange 28' of the container 2 and the lid 6 is aligned before the locking of lid 6 and insert container 4, so that a relative movement of lid 6 to the joined parts container 2 and insert container 4 is locked with the latter. For this purpose, the lid 6 is moved vertically towards the joined parts container 2 and insert container 4, so that the locking device 69, which rests against the locking device 48 of the insert container 4, is deflected transversely outwards, which subsequently pivots back, thereby engaging the Fig. The closure operating situation shown in 15a, b is formed within the second type of fixation area.
