Description

Background of the invention

[0001] The invention relates to a lid, comprising: a lid body having a groove-shaped edge region on which a clamping profile is formed for interacting with a clamping profile on an engagement region of a peripheral edge of a bucket. The invention also relates to a bucket with a base and with a peripheral side wall which, in the region of an opening of the bucket, has a peripheral edge with an engagement region with a clamping profile for interacting with a clamping profile on a groove-shaped edge region of a lid in order to close the opening of the bucket. The invention also relates to a container having such a lid and a bucket.

[0002] When a bucket is closed with a lid and filled with a liquid, particularly paint or varnish, there is a risk that the liquid could spill onto the inside of the lid during transport or mixing and dry there. When the lid, which is made of plastic, is opened, the lid is deformed and stretched. This usually causes the dried film of the contents, e.g. the dried paint, to tear and residue of the paint in the form of flakes detaches and falls into the liquid paint still in the bucket. These unwanted particles are annoyingly visible after the paint has been applied or burst from the surface that was painted, which can result in the surface having to be repainted at great expense.

[0003] Another problem with paint residue adhering to the inside of the lid is that the container may no longer be able to be sealed properly after the first opening. Paint residue on the lid also disrupts the recycling process. Therefore, additional washing and cleaning processes and corresponding resources are required during processing to remove the paint residue from the plastic material of the lid.

[0004] EP3848176A2 describes a lid having on its inside at least one lid-side in-mold label and / or a label connected to the lid in at least a partial area, which covers the inside of the lid at least up to a contact area with a container. The lid-side in-mold label and / or the lid-side label can be detachably connected as a whole to the inside of the lid. To create the detachable connection, the lid-side in-mold label and / or the lid-side label can be coated, painted, printed, and / or surface-treated.

[0005] The in-mold label described in EP3848176A2 prevents paint residue from adhering to the inside of the lid, thus improving the lid's recyclability. However, when the lid is removed from the bucket, the in-mold label may also be deformed or stretched, causing dried paint residue to detach.

[0006] EP3048060B1 describes a container having a circumferential side wall on which, in the region of an opening of the container, a circumferential container rim is formed which projects outwards and / or inwards beyond the side wall and which, for use as a sealing rim, has an upper side with a width of at least 2 mm for the application of a particularly peelable film. The welded-on peelable film can be peeled off by a consumer to gain access to the contents. If the contents are paint, this dries on the inside of the peelable film. Removing the peelable film requires considerable force, so that when the film is removed, particles may detach from the inside of the peelable film and enter the contents. In addition, a sealing device is required at the filler to seal the film. Object of the invention

[0007] It is an object of the invention to provide a lid, a bucket and a container in which the recyclability can be increased or the detachment of adhesions of a filling material when the lid is lifted can be reduced. Subject of the invention

[0008] This object is achieved according to a first aspect by a lid of the type mentioned at the outset, which has a film lid which runs on an inner side of the lid body and which has a shaped lid region which, for the detachable fastening of the film lid to the lid body, dips into the channel-shaped edge region of the lid body and extends at least in sections to an outer leg of the channel-shaped edge region.

[0009] Unlike the in-mold label described in EP3848176A2, or the label that is at least partially bonded to the inside of the lid, the film lid in the present case is generally not peelably and detachably bonded to the inside of the lid body. Rather, the film lid is attached to the lid body by the molded lid portion, which dips into the grooved edge portion and extends to the outer limb of the grooved edge portion. In principle, however, it is also possible to connect the film lid to the inside of the lid body in a peelable and detachable manner in addition to being attached by the molded lid portion.

[0010] The shaped or profiled lid region typically runs along the outer edge of the film lid. As a rule, the shaped lid region runs completely around the circumference. The shaped lid region projects beyond a generally flat or essentially flat inner region of the film lid, which rests against a generally flat or essentially flat inner region of the lid body. The film lid, in particular the shaped lid region, is typically precisely contoured to the geometry of the lid body. The shaped lid region typically has an inner leg and an outer leg.The inner leg of the shaped lid region typically lies at least partially against an inner leg of the channel-shaped edge region of the lid body and the outer leg of the shaped lid region typically lies at least partially against an outer leg of the channel-shaped edge region of the lid body. The shaped lid region can extend along its entire circumference up to the outer leg of the channel-shaped edge region. For the detachable fastening, however, it can be sufficient if the shaped lid region extends in the circumferential direction only in sections, e.g. along two or more sections running in the circumferential direction, up to the outer leg of the channel-shaped edge region. The channel-shaped edge region typically projects outwards beyond an inner region of the lid body, i.e. towards the outside of the lid body.

[0011] When attaching the film lid to the lid body, the outer leg of the shaped lid portion is moved toward the inner leg of the shaped lid portion so that the shaped lid portion can immerse itself in the channel-shaped edge portion. By shortening the distance between the two legs of the shaped lid portion, a spring effect is created which, when the shaped lid portion is immersed in the channel-shaped edge portion, presses the inner leg of the shaped lid portion against the inner leg of the channel-shaped edge portion and the outer leg of the shaped lid portion against the outer leg of the channel-shaped edge portion, thus fixing the film lid to the lid body. The film lid, releasably attached to the lid body in this way, has an additional sealing effect when closing the opening of the bucket with the lid.

[0012] The lid, which has the foil lid, can be attached to the bucket like a conventional lid during filling to close the opening, for example by bouncing, rolling or by manual placement. When the lid is lifted off the bucket, the foil lid can be detached from the lid, i.e. it remains on the bucket and is not lifted together with the lid, as described in more detail below. Once the lid is lifted off, the foil lid covers the opening of the bucket and rests loosely on the rim of the bucket and can therefore be easily removed without dislodging any adhering paint residue or breaking the dried layers of paint.

[0013] This solution eliminates the need for a sealing system to attach the film lid to the rim of the bucket. Furthermore, the film lid can be reused multiple times—if necessary, after appropriate cleaning—which is not the case with sealing film.

[0014] In one embodiment, the clamping profile, particularly in the form of a locking edge, is formed on the outer leg of the channel-shaped edge region. The clamping profile engages with a corresponding clamping profile on the engagement region of the bucket to tightly close the opening on the bucket. The arrangement of the clamping profile on the outer leg of the channel-shaped edge region is advantageous in order to allow the film lid to remain on the bucket when the lid body is lifted.

[0015] In a further embodiment, a free end of the shaped lid portion, which extends into the groove-shaped edge portion, engages behind the clamping profile, in particular the locking edge, at least in sections. When inserting the film lid, the free end or the outer edge of the shaped lid portion is guided past the clamping profile. Due to the spring action between the two legs of the shaped lid portion described above, the free end of the shaped lid portion is "fixed" behind the clamping profile or the locking edge, i.e., in this embodiment, the film lid is "clipped" into the groove-shaped edge portion of the lid body. The free end of the groove-shaped edge portion can engage behind the clamping profile along the entire circumference of the shaped lid portion.However, for fastening to the lid body, it may be sufficient if the free end of the groove-shaped edge area only partially engages behind the film lid in the circumferential direction.

[0016] The clamping profile does not necessarily have to be a locking edge that engages with a corresponding clamping profile, e.g., in the form of a groove, on the engagement area. Rather, the clamping profile on the lid body and the clamping profile on the engagement area of ​​the bucket's rim can also be other comparable holding or locking elements, e.g., hooks or the like, which enable a locking connection between the lid body and the bucket to tightly close the opening on the bucket.

[0017] In a further embodiment, the film lid has a thickness of between 40 µm and 200 µm, preferably between 50 µm and 150 µm, in particular between 50 µm and 100 µm. In order to enable the film lid to remain on the edge of the bucket or in the engagement area when the lid is removed, without additional measures having to be taken to hold the film lid on the bucket when the lid is lifted, the film lid must have sufficient elasticity, i.e. the film lid should not be too stiff. The thickness of the film lid should therefore not be too great, whereby the maximum thickness at which the film lid remains on the bucket without additional measures depends on the dimensions of the bucket. A maximum thickness of approximately 150 µm has proven to be advantageous for a bucket with an oval lid with dimensions in the order of 400 mm x 300 mm.The maximum thickness of the film lid decreases with decreasing lid surface area, i.e., lids with a smaller surface area typically require film lids with a thinner thickness. The film lid is usually formed from a flat film, for example, from a flat film blank, on which the shaped lid area is formed, e.g., by deep drawing or some other method. However, the film lid can also be manufactured by other methods, e.g., by injection molding, i.e., as an extremely thin injection-molded part (within the limits of manufacturing capabilities).

[0018] In addition to absorbing adhering paint residue, the film lid can also perform other functions. For example, depending on the material or material combination, it can exhibit various advantageous barrier properties. By selecting the appropriate material, the film lid can improve the barrier properties against oxygen, water vapor, or even the resistance to aggressive contents.

[0019] In another embodiment, the film lid is coated, surface-treated, and / or structured to increase the adhesion of the contents and / or to enhance the sealing effect with the bucket. Improved adhesion of the contents, particularly in the form of paint residue, can counteract the problem of paint residue flaking off when the lid is lifted. The sealing effect of the film lid with the bucket can also be increased through a suitable coating, surface treatment, and / or structuring.

[0020] In a further embodiment, the film lid has at least one holding aid, particularly in the form of a holding tab, projecting beyond the free end of the shaped lid region. The holding aid serves to simplify the removal of the film lid from the edge of the bucket after the lid has been removed. One or more holding aids can be attached distributed around the circumference of the film lid. For example, two holding aids in the form of holding tabs can be attached diametrically opposite each other on the outer edge of the film lid in order to remove the film lid from the bucket without paint flaking off the inside of the film lid. The holding aid can also be used to hold the film lid down when the lid body is lifted off, i.e., to prevent the film lid from being lifted from the engagement area of ​​the bucket. Ideally, however, such holding down by means of the holding aid is not necessary, i.e.the engagement of the two clamping profiles can be released and the lid body can be removed from the bucket without additional measures being required to hold the film lid to the bucket.

[0021] In a further embodiment, the lid body has at least one opening aid for pivoting the outer leg of the channel-shaped edge region in order to lift the lid body from the engagement region of the bucket, in particular without lifting the film lid from the engagement region. As described above, by pivoting the outer leg of the channel-shaped edge region on which the clamping profile is formed, the locking with the clamping profile of the engagement region of the bucket can be released and the lid body can be lifted from the bucket. In this case, the clamping profile of the lid body slides over the free end or edge of the film lid, which flexibly deflects in the process. To assist in releasing the film lid from the lid body, the user can pull the film lid downwards on the holding aid, e.g. in the form of a holding tab, when lifting the lid or the lid body, but this is not absolutely necessary (see above).It may be advantageous if the opening aid and the holding aid(s) are located at the same circumferential position on the rim of the bucket. It is not absolutely necessary for the lid to have an opening aid.

[0022] Alternatively or additionally, the opening aid or an opening aid can be provided on the bucket itself.

[0023] In a further embodiment, the lid body has on its outer side at least one stiffening profile which runs completely or partially around the circumference in the circumferential direction for stiffening the channel-shaped edge region. The stiffening profile is arranged on the outer side of the lid body at a comparatively short distance from the channel-shaped edge region. The stiffening profile extends - like the channel-shaped edge region - outwards from a flat or essentially flat inner region of the lid body. The stiffening profile can run completely around the outer side of the lid body in the circumferential direction, but the lid body can also have a plurality of stiffening profiles which are spaced apart in the circumferential direction and extend over a predetermined angular range in the circumferential direction.

[0024] In a further embodiment, the stiffening profile has at least one stiffening contour, in particular a stiffening rib, for lateral engagement with a side wall of a bucket stacked on the outside of the lid body. Stiffening ribs can be attached to the stiffening profile, which laterally fix a bucket stacked on the lid to prevent the bucket from slipping.

[0025] A further aspect of the invention relates to a bucket of the type mentioned above, in which the opening is covered by a film lid having a shaped lid portion that rests at least partially on the engagement region on the peripheral edge of the bucket. The film lid can have the properties described above in connection with the lid, particularly with regard to its thickness. The film lid can also have at least one retaining aid, for example in the form of a retaining tab, projecting beyond the free end of the shaped lid portion.

[0026] A further aspect of the invention relates to a container comprising: a lid which is designed as described above, and a bucket with a base and with a circumferential side wall which, in the region of an opening of the bucket, has a circumferential edge with an engagement region with a clamping profile for interacting with the clamping profile on the channel-shaped edge region of the lid in order to close the opening of the bucket, wherein the shaped lid region of the film lid rests at least partially on the engagement region of the bucket.

[0027] As described above, the lid body and the foil lid can be applied to the bucket in a single operation, for example, by pressing them on. The foil lid, or more precisely the molded lid area, fits precisely between the lid body and the bucket, or more precisely, the engagement area on the bucket's peripheral edge.

[0028] In one embodiment, the clamping profile forms a groove at the engagement region into which the clamping profile, in particular the locking edge, engages on the outer leg of the channel-shaped edge region of the lid body. To release the engagement between the locking edge and the groove, the outer leg of the channel-shaped edge region can be pivoted outwards and upwards to remove the lid from the bucket. The free end or edge of the film lid typically extends at the engagement region to just above the groove. When the outer leg of the channel-shaped edge region is pivoted, the locking edge of the lid body can slide over the film lid, as described above, whereby the latter flexibly deflects and prevents the film lid from being lifted off the engagement region.

[0029] In a further embodiment, the bucket has at least one opening aid for pivoting the outer leg of the channel-shaped edge region in order to lift the lid body, in particular without lifting the film lid from the engagement region. The edge of the bucket is typically a double edge, in which an apron adjoins the engagement region of the edge, which extends essentially parallel to the side wall of the bucket and has a slightly conical geometry. The opening tab is pivotally connected to the bucket and extends into the region of the apron. The opening tab can be folded from a position aligned essentially parallel to the apron into a position pivoted relative to the apron in order to at least partially release the lid from the engagement region of the edge.It is understood that other types of opening aids can also be provided on the bucket in order to release the clamping profile of the lid from the clamping profile of the engagement area of ​​the bucket.

[0030] In another embodiment, an inner leg of the grooved edge region of the lid body extends into the opening of the bucket. In other words, the inner leg of the grooved edge region of the lid body extends from the top of the bucket's peripheral edge into the interior of the bucket. This is beneficial for stabilizing the connection between the lid and the bucket. However, with the solution described above, which uses a sealing edge, such an immersion of the lid into the interior of the bucket is not possible.

[0031] In one embodiment, the material of the bucket, the lid body, and / or the film lid is polyolefin, particularly polyethylene or polypropylene, polyamide, or polyethylene terephthalate. Buckets, lid bodies, and / or film lids made of these materials are typically inexpensive to produce. Furthermore, they exhibit advantageous properties, such as high durability due to high toughness and elongation at break values. In principle, however, the lid or bucket can also be made of other plastic materials (particularly thermoplastics, possibly also thermosets).

[0032] Further advantages of the invention will become apparent from the description and the drawings. Likewise, the above-mentioned and further-described features can be used individually or in combinations according to the invention. The embodiments shown and described are not intended to be exhaustive, but rather are exemplary in nature for describing the invention. drawing

[0033] The invention is illustrated in the drawings and explained in more detail using exemplary embodiments. They show: Fig. 1 a perspective view of a lid body and a film lid, which together form a lid, Fig. 2 a view of a container which comprises the lid body and the film lid of Fig. 1and a bucket, Fig. 3 a sectional view of a channel-shaped edge region of the lid body, into which a shaped lid region of the film lid engages, Fig. 4 a representation analogous to Fig. 3 , in which the lid is placed on one edge of the bucket, Fig. 5 a representation analogous to Fig. 4 at a position on the circumference of the lid where it has an opening aid and a holding aid, Fig. 6 a perspective detailed view of a container in which the lid body has been partially lifted from the edge of the bucket without lifting the film lid, Fig. 7 a view analogous to Fig. 4 with the lid body in a partially raised position, in which the locking of a locking edge of the lid body and a groove in the engagement area of ​​the bucket has been released, and Fig. 8 shows a representation of a bucket whose opening is covered by a film lid.

[0034] Fig. 1shows a lid body 1 and a foil lid 2, which is precisely adapted to the geometry of the lid body 1. The lid body 1 with the film lid 2 detachably attached to it together form a lid 3, which is placed on a peripheral edge 5 of a bucket 4, which is Fig. 2 The lid 3 and the bucket 4 together form a container 6.

[0035] Fig. 3 shows a detail of the lid 3 with a groove-shaped edge region 7 of the lid body 1, which projects towards the outside of the lid body 1 over a flat inner region 8 of the lid body 1 in the example shown. The inner region 8 does not necessarily have to be flat; rather, it can be cambered or have a projection. The film lid 2 runs along an inner side of the lid body 1 and has a shaped lid region 9which, for the detachable fastening of the film lid 2 to the lid body 1, dips into the groove-shaped edge region 7 of the lid body 1. The shaped lid region 9 is essentially V-shaped and has an outer leg 10a and an inner thigh 10b The groove-shaped edge region 7 is also essentially V-shaped and has an outer leg 11a and an inner thigh 11b The outer leg 10a of the shaped lid portion extends to the outer leg 11a of the groove-shaped edge portion 7 and lies with a free end 12or an outer edge on the inside of the outer leg 11a of the groove-shaped edge region 7. The inner leg 10b of the shaped cover region 9 lies flat against the inside of the inner leg 11b of the groove-shaped edge region 7 in the example shown. It is understood that the geometry of the groove-shaped edge region 7 and the shaped cover region 9 differs from that shown in Fig. 3 shown shape, for example both may have a substantially U-shaped geometry.

[0036] In order to insert the shaped lid portion 9 into the grooved edge portion 7 of the lid body 1, it is necessary to shorten the lateral distance between the outer leg 10a and the inner leg 10b of the shaped lid portion 9. The film lid 2 and thus also the shaped lid portion 9 are made of a plastic material which, when the distance between the two legs 10a, 10b is reduced, acts like a spring and presses the outer leg 10a or the free end 12 of the shaped lid portion 9 against the outer leg 11a of the grooved edge portion 7 and the inner leg 10b of the shaped lid portion 7 against the inner leg 11b of the grooved edge portion 7. The shaped or profiled lid portion 9 can be produced from a flat film, for example by deep drawing.In the example shown, the film cover 2 has a thickness d between 40 µm and 200 µm, more precisely between 50 µm and 150 µm.

[0037] As in Fig. 3 As can also be seen, when the two legs 10a, 10b were pressed together, the free end 12 of the shaped cover area 9 was clamped on a clamping profile formed on the outer leg 11a of the groove-shaped edge area 7 in the form of a circumferential locking edge 13 and engages behind it. In this way, the film lid 2, or more precisely the shaped lid area 9, is fixed in the groove-shaped edge area 7 of the lid body 1.

[0038] The Fig. 3 The lid 3 shown can be pushed onto the edge 5 of the bucket 4 in the usual way, which is Fig. 4 shown in a detailed view. The bucket 4 comprises a Fig. 2 shown floor 14 and a surrounding side wall 15, which is in the area of Fig. 1shown opening 16 of the bucket 4 has the peripheral edge 5. The peripheral edge 5 has an engagement area 17 which has a clamping profile 18 in the form of a circumferential groove, which cooperates with the clamping profile in the form of the locking edge 13 of the lid body 1 to lock the lid 3 to the bucket 1 and thereby seal the opening 16 of the bucket 4. Adjoining the engagement area 17 is an apron running essentially parallel to the circumferential side wall 15 19The shaped lid region 9 of the film lid 2 rests with its outer leg 10a partially on the engagement region 17 of the rim 5 of the bucket 4. The film lid 2 has a sealing function. The film lid 2 protects the lid body 1 of the lid 3 from adhesion of a filling material, for example in the form of paint residues, which adhere to the inside of the film lid 2 and not to the inside of the lid body 1. To increase the adhesion of the filling material, for example in the form of paint residues, and / or to increase the sealing effect with respect to the bucket 4, the film lid 2 can be coated, surface-treated and / or structured - typically on its inside. The film lid 2 can also fulfill other functions, for example a barrier function.

[0039] As in Fig. 4 and in Fig. 1As can be seen, the cover body 1 has on its outer side four stiffening profiles running circumferentially over an angle of slightly less than 90° 20 which extend vertically upwards from the flat inner region 8 of the lid body 1. The stiffening profiles 20 are arranged at a comparatively small distance from the channel-shaped edge region 7 of the lid body 1 in order to stiffen it. As shown in Fig. 4 As can be seen, the stiffening profiles 20 have, on their side facing away from the channel-shaped edge region 7, several stiffening ribs distributed in the circumferential direction 21 In the example shown, the stiffening ribs 21 also serve to attach a side wall 15' another bucket 4', which is stacked on the outside of the lid body 1, as shown in Fig. 4 is indicated by dashed lines.

[0040] In order to simplify the detachment of the lid body 3 from the peripheral edge 5 of the bucket 4, the lid body 3 has an opening aid 22 on which Fig. 5 and in Fig. 6 can be clearly seen. In the example shown, the opening aid 22 is designed in the form of two annular projections which extend laterally outwards from the channel-shaped edge region 7 and into which an operator can engage with two fingers in order to pivot the lid body 3, more precisely the outer leg 11a of the channel-shaped edge region 7 of the lid body 1, upwards and in this way to lift the lid body 1 from the engagement region 17 of the circumferential edge 5 of the bucket 4.

[0041] As in Fig. 6As can be seen, when the lid body 1 is lifted from the engagement area 17 on the peripheral edge 5 of the bucket 4, the film lid 2 remains on the engagement area 17 and is not lifted upwards, i.e. it continues to rest on the engagement area 17. In order to counteract the lifting of the film lid 2, an operator can simultaneously press down a holding aid projecting beyond the free end 12 of the shaped lid area 9 while lifting the lid body 1, which in the example shown is in the form of a holding tab 23 is trained.

[0042] However, holding down the film lid 2 with the aid of the retaining tab 23 is not absolutely necessary, since when the locking mechanism is released, the locking edge 13 on the lid body 1 can slide over the free end or the edge 12 of the film lid 2, which in this case flexibly deflects, so that the film lid 2 is not lifted off when the lid body 1 is lifted off, as is the case in Fig. 7is shown in dashed lines. After the lid body 1 has been lifted off, the film lid 2 with the shaped lid area 9 rests at least partially on the engagement area 17 of the peripheral edge 5 of the bucket 4.

[0043] Fig. 8 shows the bucket 4 after lifting the lid body 1. As in Fig. 8As can be seen, the film lid 2 covers the opening 16 of the bucket 4. The loosely placed film lid 2 can be lifted off the bucket 4 or from its peripheral edge 5, for which purpose an operator can grasp the film lid 2 at the retaining tab 23. Lifting the film lid 2 off the bucket 4 requires less force than with a sealing film and can typically be accomplished without detaching any contents adhering to the inside of the film lid 2. To facilitate the lifting of the film lid 2, a further retaining tab 23 can be formed on the film lid 2, which can be arranged, for example, diametrically opposite to the Fig. 8 shown retaining tab 23 can be positioned on the edge of the foil cover 2.

[0044] Alternatively or in addition to the opening aid 22 on the lid 3, an opening aid can be provided on the bucket 4, for example a pivotable tab on the edge 5 of the bucket 4. Such a tab can be pivoted upwards in order to pivot the outer leg 11a of the channel-shaped edge region 7 of the lid body 1 upwards in order to lift the lid body 1 from the edge 5 of the bucket 4.
