Description

The invention relates to a bucket with a base and with a peripheral side wall, the bucket having a peripheral rim in the area of an opening with an engagement area for interacting with a lid. The invention also relates to a container with such a bucket and with a lid which cooperates with the engagement area on the peripheral edge of the container to close the opening.

In the context of this application, a bucket is understood to be a container with a circumferential, generally slightly conically inclined side wall and an opening, which typically extends over the entire upper side of the bucket. The basic shape of the bucket, which typically corresponds to the basic shape of the bottom, is arbitrary. The bucket can, for example, have an oval, round, rectangular or square basic shape. In the context of this application, a bucket is also understood to mean a can-shaped container in which the side wall is cylindrical.

It is known to design packaging containers as hybrid containers in order to reduce their plastic content, which have components made of two or more different materials. In addition to a plastic material, hybrid containers often have another material that is made from a renewable raw material, e.g. cardboard, cardboard or the like, to reduce the plastic content.

In the DE 295 130 93 U1 describes a two-part packaging container comprising a deep-drawn plastic cup and a cardboard sleeve formed from a cardboard blank with an overlap seam and tapering downwards, the cardboard sleeve fitting snugly against the plastic cup and stabilizing its cup walls. The plastic cup made of a polyolefin and the cardboard sleeve are detachably fitted into one another and a bottom part made of a cardboard material is provided.

In the WO 98/13270 describes a stackable combi-packaging container that has a cup-shaped plastic inner part deep-drawn from a film, which is encased by an outer part made of a different material, for example paper, cardboard material or another plastic. Snap-in means can be provided on the plastic inner part, into which the jacket-like outer part can snap detachably for fixing to the cup-shaped plastic inner part. The combination packaging container can be, for example, a yoghurt, ice cream or margarine tub.

In the US 2020/0307887 A1 describes a packaging assembly comprising a carton with side and bottom walls and an open top which can be closed by a lid. A self-supporting plastic liner fits inside the carton and is used to hold liquids, viscous material, or particulate material. The plastic liner has a side wall, a closed bottom end, and an open top end with an outwardly projecting rim. The rim has a radially extending flange portion and a depending skirt portion. When the self-supporting plastic liner is inside the carton, the dependent skirt portion of the rim overhangs the side walls of the carton.

The object of the invention is to provide a bucket and a container that can be produced with a reduced use of material.

According to a first aspect, this object is achieved by a bucket of the type mentioned at the outset, in which the peripheral edge is designed to be dimensionally stable and in which the bottom and the peripheral side wall are designed as a film.

The reduction of the wall thickness of conventional buckets, which are produced using the injection molding process, is not easily possible due to the comparatively long flow paths of the liquid plastic material. The bucket according to the invention is therefore typically made up of several parts, i.e. at least two parts. The peripheral edge can be produced in an injection molding process. The film base and the film side wall can either be formed from a flat blank or - depending on the dimensions of the bucket - possibly produced as a molded part by deep drawing.

In the context of this application, the term "rigid" is understood to mean that a component, e.g. the peripheral edge, does not change its shape during normal use and can at most be deformed elastically without considerable effort. Compared to a dimensionally stable component, which typically has a thickness of at least 0.6 mm, a component that is designed as a film is significantly thinner. The thickness of the base and the peripheral side wall are generally more than approximately 50 μm and less than approximately 300 μm. The bottom and the surrounding side wall, which are designed as a film, are flexible, i.e. they are not dimensionally stable components.

Due to the significantly lower wall thickness of the bottom and the surrounding side wall compared to conventional buckets, the weight and thus the use of materials required for the production of the bucket can be significantly reduced. The dimensionally stable peripheral edge with the grip area makes it possible, as in a conventional bucket, to close the opening of the bucket in a locking and sealing manner with a lid, it also being possible for the bucket to be opened and closed again several times. The bucket can therefore be handled by an operator like a conventional bucket in order to empty the filling substance(s) from the bucket.

In one embodiment, the peripheral edge has a side wall section and a flange section that protrudes outwards beyond the side wall section and is adjoined by a skirt, the engagement area being formed on the flange section, and the engagement area preferably having a clamping profile for interacting with a clamping profile on a Having inside an edge of the lid. In this case the rim of the pail forms a double rim which has a side wall section running along the foil side wall. The side wall section is typically adjoined at its upper end by a flange section which protrudes outwards, e.g. The skirt typically extends just below the engagement area for attachment of the lid formed on the flange portion. To stiffen the skirt, stiffening ribs are generally provided, which extend from the outside of the side wall section to the inside of the skirt. The bucket may have an opening tab extending from the skirt into the engagement area to facilitate removal of the lid for a user. Other components which are known from conventional buckets and simplify the handling of the bucket for an operator, for example holding elements for a carrying handle, carrying handles or the like, can also be attached to the peripheral edge.

The clamping profile on the flange area can be, for example, a groove that interacts with a corresponding clamping profile in the form of a locking edge that is formed on the cover. It goes without saying that the clamping profile of the flange area and the clamping profile of the cover can also be designed in other ways.

In a further embodiment, the peripheral side wall has a fastening section which is connected to the peripheral edge, in particular to the side wall section, preferably on its inside, in a fixed or detachable manner, in particular in a detachable, peelable manner. The fastening section typically forms a section at the upper, free end of the peripheral foil side wall. The fastening section can be connected to the peripheral edge, in the case of the double edge described above to the side wall section, in different ways. For example, a non-detachable connection can be produced by plastic welding or by overmoulding the side wall with the plastic material of the peripheral edge in an injection molding process during the manufacture of the bucket. In the event that the film side wall is detachably connected to the peripheral edge, in particular in a detachable, peelable manner, the plastic material of the film side wall is not compatible with the plastic material of the peripheral edge, so that no common melt composite is formed. The detachable connection of the side wall to the peripheral rim is advantageous because in this case the peripheral side wall together with the base and the peripheral rim can be disposed of or recycled separately after the bucket has been used.

In principle, it is possible to connect the side wall to the inside or to the outside of the peripheral edge or the side wall section. As a rule, it is advantageous if the side wall is connected to the inside of the surrounding rim, since in this case it may be possible to avoid the contents coming into contact with the surrounding rim (see below). In this case, if the side wall is detachably connected to the peripheral edge in the fastening section, the peripheral edge can be reused, if necessary.

In a further development, the fastening section of the side wall extends on the inside of the peripheral edge, preferably of the side wall section, up to a contact area with the cover. In the contact area, the inside of the fastening section of the foil side wall comes into contact with the inside of the lid. The covering of the inner side of the peripheral edge up to the contact area ensures that the inner side of the peripheral edge or the side wall section does not come into contact with the filling as soon as the bucket is closed with the lid.

In this case, if the lid has a label or in-mould label on the inside made of a food-compliant material or possibly a coating or the like made of a food-compliant material, or if the lid itself is made of a food-compliant material, the corresponding container can have food conformity as a whole, even if the plastic material of the dimensionally stable peripheral edge itself is not food-compliant, for example because the plastic material of the peripheral edge is formed entirely or partially from a non-food-compliant regenerated plastic.

In a further embodiment, the base forms a first film and the circumferential side wall forms a second film, which are connected to one another in an overlapping area in a fixed or detachable manner, in particular in a detachable manner that is peelable. The floor and the side wall can form a common foil molding, which is typically produced by deep drawing. However, due to the usually comparatively large height of the bucket, manufacture by deep-drawing may not be readily possible. Accordingly, it is favorable if the base and the peripheral side wall form two separate film components which are typically firmly connected to one another in an overlapping area, for example via a welded joint. In this way, buckets with comparatively large dimensions can also be produced.

In a further development, the base has a section which extends along the side wall and which overlaps in the overlapping area with the peripheral side wall, preferably with an outside of the side wall. It has proven advantageous if the overlapping area is formed at the lower end of the side wall. In this way, the bottom can be designed as a flat film, the peripheral edge of which is turned over or folded in order to be connected to the side wall in the overlapping area. Since the section extending along the side wall may

having incisions, it is favorable to connect the section extending along the side wall to the outside of the side wall, but this is not absolutely necessary, i.e. the section can alternatively overlap in the overlapping area with the inside of the side wall. The connection can be made by plastic welding or in some other way. The area of overlap typically extends along the side wall over a height of about 5-15 mm.

In a further embodiment, two edges of the circumferential side wall lying opposite one another in the circumferential direction are connected to one another in a fixed or detachable manner at an overlapping seam, in particular in a detachable, peelable manner. In this case, the film side wall can be made from a flat film, i.e. from a flat film blank. The two edges can be welded together along the overlapping seam, for example. As described above in connection with the fastening section of the side wall, the connection can be designed to be permanent or detachable, in particular detachable so that it can be peeled off. This simplifies the disposal of the foil side wall. The latter is typically only favorable in the event that the filling is solid, e.g. if the filling is frozen. If a liquid filling material is used, there is a great risk that the liquid filling material will leak out unintentionally. In principle, however, it is possible or favorable in the case of a solid filling material to form the connection in a detachable manner if the side wall can be removed quickly and easily by simply tearing open the peel seam or the peelable connection.

In a further embodiment, the bucket comprises a dimensionally stable ring, which surrounds a lower end of the side wall and preferably an area of the base adjoining the side wall and which can be fixed or detached, in particular peelably detached, to the outside of the side wall and/or to the outside of the soil is connected. The rigid ring stabilizes the bucket at the lower end of the side wall. The dimensionally stable ring can be used in particular to cover the overlapping area at the lower end of the side wall. As described above in connection with the fastening section and with the overlapping seam of the side wall, the rigid ring can be firmly or detachably connected to the outside of the side wall and/or to the outside or underside of the base.

In a further embodiment, the bucket has a dimensionally stable base area which is connected to an outside of the base in a fixed or detachable manner, in particular in a peelable detachable manner. The floor area can be fully or partially, i.e. partially, connected to the outside or underside of the floor. Due to the dimensionally stable bottom area, the bucket can be additionally stabilized, for example to increase its stability. However, such a stabilization is not absolutely necessary. In the event that the bucket has the rigid ring described above, the rigid bottom portion can be attached to the outside of the bottom within the rigid ring that is connected to the outside of the bottom, or the rigid bottom portion covers the bottom also in the region of the rigid ring and the rigid ring partially covers the floor area.

In another embodiment, the bucket includes a peripheral rim in front preferably detachably connected support body, in particular in the form of a support sleeve, which surrounds the side wall at least partially in the vertical direction and/or in the circumferential direction and preferably protrudes in the vertical direction above the bottom of the bucket. The support body is typically designed either as a support sleeve or as a support shell. The latter has a bottom part in addition to a lateral surface, so that the supporting shell not only surrounds the foil side wall but also the foil bottom of the bucket at least partially, in particular completely.

In the event that the support body is designed as a support sleeve, this is connected at its upper end to the peripheral edge of the bucket and can be connected at its lower end to the dimensionally stable ring. However, it is also possible for the support sleeve to be connected to the peripheral rim only at its upper end, but not to the dimensionally stable rim, the bottom or the side wall of the bucket. The support sleeve preferably protrudes above the bottom of the bucket in the vertical direction. In this case, the lower edge of the support sleeve forms a support contour for the bucket. If the supporting body is designed as a supporting shell, the bottom part of the supporting shell forms the supporting surface of the bucket.

The support body is preferably made of cardboard, corrugated cardboard or the like, but the support body can also be made of a—preferably recyclable—plastic material. The supporting body can be a one-way or a reusable component. It is possible for the supporting body to be produced as a molded component, but it is also possible for the supporting body to be composed of two or more components in the form of the supporting shell, similar to the film bottom and the film side wall of the bucket. Both in the event that the support body is designed as a support sleeve and in the event that the support body is designed as a support shell, it can be formed from a flat blank like the peripheral side wall. In this case, too, two opposite edges of the flat blank are connected to one another in a non-detachable or detachable manner, in particular detachably in a peelable manner, along an overlapping seam.

The support body in the form of the support sleeve or the outer surface of the support shell can have a conical geometry that is adapted to the conical geometry of the circumferential side wall of the bucket. However, it is also possible for the support sleeve or the outer surface of the support shell to have a cylindrical geometry, i.e. that the cross section of the support sleeve or the support shell is constant in the height direction.

In a development of this embodiment, the peripheral edge has a receiving contour for the detachable connection of the support body, which is preferably formed between the side wall section and the skirt and/or on the outside of the skirt of the peripheral edge. The receiving contour can be used, for example, to produce a clamping connection between the support body and the peripheral edge, and for this purpose can have one or more receiving gaps into which the upper end of the support body is inserted. Such gaps can be formed, for example, on stiffening ribs that serve to stiffen the skirt and extend from the outside of the side wall section to the inside of the skirt. Alternatively or additionally, the outside of the apron can also have a receiving contour for the supporting body. The receiving contour can be, for example, one or more contact surfaces which are formed at the upper end of the apron and protrude outwards over the apron and on which the upper side of the support body is brought into contact. In the event that the supporting body is connected to the peripheral edge on the outside of the skirt, it is advantageous if the supporting body has a cylindrical geometry at least at its upper end, which is adapted to the cylindrical geometry of the peripheral skirt. In the context of this application, a cylindrical geometry is not understood to mean a circular-cylindrical geometry; rather, the cylindrical shape corresponds to the basic shape of the bucket, which can be oval, rectangular, square, etc., for example.

In a further embodiment, the supporting body has at least one latching element for latching interaction with the dimensionally stable ring and/or with the peripheral edge. The at least one latching element can be, for example, a hook-shaped latching element that protrudes outwards or inwards beyond the rest of the support body, but this is not absolutely necessary. For example, if the supporting body is attached to the receiving contour on the outside of the apron, the locking element can be designed as an opening in the supporting body, into which a locking element engages in the form of a projection projecting beyond the outside of the apron.

In the event that the support body is detachably connected to the rigid ring, the latching element can be designed, for example, in the form of a latching hook which protrudes inward beyond the support sleeve or the outer surface of the support shell. When pushing on the support sleeve or support shell, which is typically conical in this case, starting from the underside of the bucket, the hook-shaped latching element is first on the outside guided along the side of the rigid ring until it overlaps the rigid ring on its upper side, so that the support body cannot be pulled downwards from the peripheral edge without the application of force.

In the event that the support body is detachably connected to the outside of the apron, it may be necessary to provide recesses for components formed on the apron at the upper end of the support body, which protrude beyond the apron to the outside. For example, recesses can be provided in the supporting body for receiving mounting points of a carrying handle, which is fastened to the peripheral edge of the bucket. The two ends of the support bracket typically extend outwardly from the edge of the skirt at the mounting locations, which is why the recesses in the support body are necessary. The same also applies to one or more carrying handles, which may be attached to the peripheral edge and protrude beyond the apron.

As described above, an opening tab is typically attached to the surrounding skirt and extends into the engagement area. If the support body is detachably connected to the outside of the apron, a recess can be formed in the support body, which releases the opening tab. Alternatively, a detachable area of the support sleeve can be formed in the area of the opening flap, which can be separated from the rest of the support sleeve by an operator along a predetermined breaking point, e.g. along a perforation line, in order to gain access to the opening flap. In this case, the detachable area of the support sleeve can also serve as a tamper-proof seal.

In a further development, the peripheral edge, in particular the protruding flange area, has a bearing surface for supporting a further support sleeve of a further bucket when stacking a plurality of buckets of the same construction on top of one another. In this case, the support sleeve or the additional support sleeve is typically cylindrical. The upper sides of several projections projecting beyond the outside of the apron can serve as a support surface, the underside of which forms the contact surface for the upper side of the support sleeve, which is connected to the peripheral edge of the lower bucket when stacked.

In the event that the support sleeve is of conical design, the upper side of a lid of a lower bucket when stacked typically forms the bearing surface for the further support sleeve of a further upper bucket when stacked. In the event that the buckets do not have a support sleeve when stacked, the inherent rigidity of the film side wall is usually not high enough to withstand the load when another bucket is stacked. In this case, several buckets can be stacked on top of each other, e.g. using a stacking aid, for example a cardboard grid or the like.

In a further embodiment, the base and/or the peripheral side wall have a plurality of film layers which are preferably detachably connected to one another in a peelable manner. The foils for the base and the side wall can also be constructed in multiple layers in order to be able to detach individual layers after use. In this way, once the individual film layers that have come into contact with the contents have been removed, a clean, refillable bucket or container is available again.

A further aspect of the invention relates to a container, comprising: a bucket, which is designed as described above, and a lid which cooperates with the gripping area on the peripheral edge of the bucket to close the opening. As described above, the inside of the lid can have an (in-mold) label made of a food-compliant material or possibly a coating or the like made of a food-compliant material. If in this case the bottom and the peripheral side wall, which extends into the contact area with the lid, are also made of a food-grade material or consist of a food-grade material, the container as a whole can have food-grade conformity, even if it is the material of the surrounding edge is not a food-compliant material. In this way, an effective barrier effect can also be achieved with respect to the contents, which can result in the extension of the best-before date of the contents, for example.

In one embodiment, a film component in the form of a label is applied to an inside of the lid, which preferably has a plurality of film layers which are connected to one another in a detachable manner, in particular in a peelable manner. Even in the case of a film component which completely or partially covers the inside of the lid, it can be advantageous to be able to detach individual layers after use, particularly if they have come into contact with the filling.

The film components described above and the dimensionally stable components are typically made from plastics that are customary for buckets, in particular from recyclable plastics, possibly with the exception of the support body (see above). Both Plastics can be, for example, polyamides (PA), polypropylene (PP), polyethylene (PE), polybutylene terephthalate (PBT) or polyolefins in general. However, plastics based on renewable resources, biodegradable plastics, composite materials and cardboard/paper can also be used.

As has been described above, the foil components in particular do not necessarily have to consist of a single material, but rather they can also be laminates. In the case of a laminate, several film layers are glued together, whereby the adhesive connection can be designed to be peelable, for example (see above). The film components, in particular the peripheral side wall, can also be printed and/or colored. The use of transparent film components is also possible. The structure of the foil components depends on the requirement profile of the bucket depending on the respective filling and can be individually adapted. For example, by choosing suitable foil materials, the barrier properties of the bucket against oxygen, water vapor or the resistance of the bucket to aggressive contents can be increased.

Further advantages of the invention result from the description and the drawing. Likewise, the features mentioned above and those detailed below can be used according to the invention individually or collectively in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

This in 1 Container 1 shown comprises a container in the form of a bucket 2 and a lid 3. The bucket 2 has a base 4 and a peripheral side wall 5, which is slightly conical. The bottom 4 and the peripheral side wall 5 are designed as a film. The bucket 2 also has a circumferential, dimensionally stable edge 6 which is arranged in the area of an opening 7 at the upper end of the bucket 2 . When displaying 1 the opening 7 is closed with the cover 3.

The bucket 2 also has a circumferential, dimensionally stable ring 8, which surrounds a lower end of the side wall 5 and an area of the base 4 adjoining the side wall 5 and which is fixed or detachable, for example peelable detachable, to an outer side 5a of the side wall 5 and / or is connected to an outer side 4a of the floor 4. At the in 1 In the example shown, the dimensionally stable ring 8 is welded to the outside 5a of the side wall 5 and rests against the outside 4a of the base 4, i.e. there is no fixed connection between the base 4 and the dimensionally stable ring 8.

the inside 1 The bucket 2 shown can have a bottom part--not shown in the drawing--which is fixed or detachable, in particular detachable and peelable, to the outside or underside of the bottom 4. The base part can run inside the rigid ring 8, but it is also possible for the base part to cover the entire base 4 on its outside 4a and for the rigid ring 8 to cover the base part on its underside.

2 shows the container 1 from 1 , in which the bucket 2 additionally has a support body in the form of a support sleeve 9 . In the example shown, the support sleeve 9 surrounds the entire peripheral side wall 5 and projects downwards over the base 4 and over the section of the rigid Rings 8, which runs along the outside or underside 4a of the floor 4. At the in 2 example shown, the support sleeve 9 has a conical geometry which is adapted to the conical geometry of the side wall 5 of the bucket 2 .

The support sleeve 9 is detachably connected to the peripheral edge 6 and to the dimensionally stable ring 8, as explained below with reference to detailed illustrations of the peripheral edge 6 and the ring 8, which are shown in 3a,b are shown.

the inside 3a The circumferential edge 6 of the bucket 2 shown in detail is designed as a substantially U-shaped double edge in the example shown. The circumferential edge 6 has a side wall section 10, on the inside 10a of which a fastening section 11 of the circumferential side wall 5 is fastened. In the example shown, the peripheral side wall 5 is a peelable film that is peelably connected to the inside 10a of the peripheral side wall 5 at the attachment section 11 in a detachable manner. As in 3a can also be seen, the fastening section 11 extends along the inside 10a of the peripheral side wall 5 to a contact area 12 with the cover 3, i.e. the fastening section 11 of the peripheral foil side wall 5 covers the inside 10a of the side wall section 10 of the peripheral edge 6 in the entire area in which it can come into contact with a filling material in the bucket 2 .

The peripheral edge 6 has a flange section 13 which protrudes outwards beyond the side wall section 10 . The flange section 13 is followed at the bottom by an apron 14 which is spaced apart from the side wall section 10 and which is designed to run around in a cylindrical shape. As in 3a can also be seen, an engagement area 15 is formed on the flange portion 13, which is used to interact with the lid 3 to close the opening 7 on the bucket 2. In the example shown, the engagement area 15 has a clamping profile 16 in the form of a circumferential groove which interacts with a clamping profile of the cover 3 , which is designed in the form of a circumferential locking edge 17 on the outer edge of the cover 3 .

As described above, the bottom 4 and the peripheral side wall 5 of the emerald 2 are designed as a film. The bottom 4 and the peripheral side wall 5 have a thickness or a wall thickness of the order of between approximately 50 μm and approximately 300 μm. The dimensionally stable edge 6, on the other hand, has a wall thickness of more than approximately 0.7 mm. The bottom 4 forms at the in 3b example shown a first film, the side wall 5 forms in the in 3b shown example, a second film, which is connected in an overlapping area 18 with the floor 4, welded in the example shown, is. In this case, the base 5 has a section 19 which extends in the direction of the side wall 5 and which overlaps with the outside 5a of the peripheral side wall 5 in the overlapping region 18 . As in 3b As can be seen, the dimensionally stable ring 8 covers the overlapping area 18 and is connected indirectly, ie via the section 19 of the bottom 4 extending in the direction of the side wall 5, to the outside 5a of the side wall 5. As in 3b can also be seen, the dimensionally stable ring 8 has at its upper end a projection 20 which protrudes in the direction of the outside 5a of the side wall 5 and which engages over the section 19 of the base 4 which extends in the direction of the side wall 5 . In the event that the dimensionally stable ring 8 is subsequently connected to the section 19 of the base 4 that extends in the direction of the side wall 5, it is not absolutely necessary for the dimensionally stable ring 8 to have the in 3b Has projection 20 shown.

In the example shown, the base 4 is made from a flat sheet of foil. The peripheral side wall 5 is also formed from a flat sheet of film by cutting two opposite edges of the sheet of film along an in 1 and in 2 shown overlap seam 21 fixed or detachable, for example peelable detachable, connected to each other.

The peripheral edge 6 of the bucket 2 has in the 3a The example shown has a receiving contour in the form of a plurality of receiving gaps 22 for the detachable connection to the support sleeve 9 . The receiving gaps 22 are formed on stiffening ribs 23 which serve to stiffen the skirt 14 and which extend from the outside of the side wall section 11 to the skirt 14 . To produce the detachable connection, the upper end of the support sleeve 9 is pushed or plugged into the respective receiving gap 22 from below, or the bucket 2 is inserted into the support sleeve 9 from above, as is shown in 4 is indicated.

As in 4 can also be seen, the support sleeve 9 also has an overlapping seam 25 and is made from a flat blank. In the example shown, the material of the support sleeve 9 is cardboard, but the material of the support sleeve 9 can also be a different material, for example corrugated cardboard or a plastic material.

As in 4 can also be seen, the support sleeve 9 has a more at its lower end number of hook-shaped latching elements 26, which protrude inwards over the support sleeve 9 or over its conical lateral surface. When the support sleeve 9 is slid onto the bucket 2 from below, the conical outer surface of the support sleeve 9 is guided along the outside of the rigid ring 8, with the latching elements 26 being pressed outwards. As soon as the hook-shaped latching elements 26 have reached the upper side of the rigid ring 8 , they are deflected inward and project beyond the projection 20 formed at the upper end of the rigid ring 8 . The latching elements 26 prevent the support sleeve 9 from unintentionally detaching from the bucket 2 when the bucket 2 is lifted. As described above, the support sleeve 9 protrudes in the vertical direction over the base 4 and over the rigid ring 8 so that its peripheral edge contour can serve as a support surface for the bucket 2 .

The support sleeve 9 enables several of the in 2 to stack the containers 1 shown on top of each other, as is the case in 5 is shown: In this case, another, upper container 1' is stacked on a lower container 1, in that the further support sleeve 9' of the further bucket 2' of the further container 1', more precisely its peripheral edge contour on the upper side of the lid 3 of the lower bucket 2 of the lower container 1 is placed. The support sleeve 9 of the lower bucket 2 absorbs the weight of the other bucket 2' and prevents the surrounding film side wall 5 of the lower bucket 2 from deforming when stacked.

In the 5 The stacking shown is generally not possible without the provision of the support sleeve 9 on a respective bucket 2 . Will more of the in 1 shown bucket 2, which have no support sleeve 9, stacked on top of each other, a stacking aid is usually required, for example a cardboard grid or the like, in which the container 1 can be introduced during stacking.

6 shows a container 1, which differs from that in 2 The container 1 shown differs in the design of the support sleeve 9: Unlike in 2 points the in 6 illustrated support sleeve 9 has a cylindrical geometry. The cylindrical support sleeve 9 is only connected at its upper end to the circumferential edge 6 of the bucket 2, but at its lower end there is no connection to the rigid edge 6 of the bucket 2, as is shown in 7a,b can be seen.

7a shows a receiving contour 22 for the support sleeve 9, which is formed on the outside of the skirt 14 in this case. In the example shown, the receiving contour 22 is a plurality of contact surfaces for the upper end of the support sleeve 9 which protrude outwards beyond the outside of the skirt 14 and which are formed on the underside of projections 27 protruding beyond the outside of the skirt 14 . As in 8th As can be seen, the projections 27 are distributed uniformly in the circumferential direction on the skirt 14 . The bucket 2 rests with its contact surfaces 22 on the cylindrical support sleeve 9 .

In order to prevent the support sleeve 9 from detaching from the bucket 2 when the container 1 is lifted, the cylindrical support sleeve 9 has a plurality of latching elements 26 which are offset laterally in the circumferential direction relative to the protruding projections 27 . As in 7a as can be seen, the hook-shaped latching elements 26 protrude outwards beyond the lateral surface of the support sleeve 9 . As also in 7a As can be seen, at the lower end of the apron 14 there are a plurality of locking elements 28 in the form of outwardly protruding projections which engage in openings which are formed in the lateral surface of the support sleeve 9 in the area of the hook-shaped locking elements 26 to prevent unintentional loosening to prevent the support sleeve 9 from the bucket 2. If the cylindrical support sleeve 9 is made of cardboard, the plurality of locking elements 28 can be in the form of U-shaped punched-out portions 26, which are deformed when they come into contact with the more dimensionally stable locking elements 28 of the bucket 2 and only after the deformation protrude outwards beyond the lateral surface of the support sleeve 9.

As in 8th As can be seen, the bucket 2 has an opening tab 29 which is formed on the skirt 14 and which extends upwards into the engagement area 13 of the peripheral edge 6 with the lid 3. The opening tab 29 is pivoted outwards by an operator in order to lift the lid 3 . In order to enable the operator to access the opening tab 29 when the support sleeve 9 is pushed onto the bucket 2, the support sleeve 9 has a detachable area 30 at its upper end, which can be attached via predetermined breaking points, more precisely via a perforation, to the remaining support sleeve 9 is connected.

As in 8th can also be seen, the bucket 2 has a carrying handle 31 which is connected to two mounting points 32 on the bucket 2, more precisely on the apron 14. The two ends of the support bracket 31 project outwards over the apron 14 at the mounting points 32 . In order to create a free space for the mounting points 32 and for the support bracket 31, the support sleeve 9 has two recesses 33 at its upper end, of which 8th one is illustrated. The alignment of the support sleeve 9 in the circumferential direction is predetermined by the recesses 33 when the support sleeve 9 is pushed on. This way will For example, it is ensured that the detachable area 30 of the support sleeve 9 covers the opening tab 29 on the apron 14 of the bucket 2 .

9 shows two bundles 1, 1' stacked on top of each other as in 6 or in 8th are shown formed. When stacked, the second, upper container 1' is placed on support surfaces 34, which cover the upper side of the in 7a and 8th form projections 27 shown, the underside of which form the contact contour 22 for the support sleeve 9 . The bearing surfaces 34 are necessary because the cylindrical support sleeve 9 is not like that in 5 shown, conical support sleeve 9 can be parked on the top of the lid 3.

It goes without saying that it is possible to deviate from the configuration of the container 1 or the bucket 2 shown above. For example, instead of a support sleeve 9, a support shell can be used which has a base or a base part. The usually detachable connection of the support shell to the rest of the bucket 2 can be done as described above.

The material of the base 4 and the side wall 5, the dimensionally stable peripheral edge 6 and the dimensionally stable ring 8 is typically plastic, in particular polyethylene, polypropylene, polyamide, PET or polyolefins in general. As described above, the support sleeve 8 is typically not made of a plastic material, but this is also possible in principle. If necessary, the support sleeve 9 can be used several times.

In the event that as in 1 and in 2 shown, the inside of the peripheral edge 6 is covered by the film side wall 5 at least up to the contact area 12 with the cover 3, if the side wall 5 is a peelable film, the peripheral edge can also be covered if necessary 6, which in this case does not come into contact with the filling material, can be used several times if the foil side wall 5 is detached from it. In principle, both the base 4, the side wall 5 and a film component (not shown) in the form of a label (possibly an in-mold label) on the inside of the lid can have a plurality of film layers that are detachably connected to one another in a peelable manner are. In this way, individual soiled layers can be removed after use and a clean, refillable container 1 is available again.
