Definitions

  • 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.
  • a bucket is also understood to mean a can-shaped container in which the side wall is cylindrical.
  • the applicant has become aware of a container made of plastic in the form of a bucket, in which at least one in-mould label or at least one label is attached to an inside of the peripheral side wall and to an inside of the bottom.
  • the bottom (in-mold) label has a portion extending along the inside of the side wall that overlaps the wall-side (in-mold) label.
  • the (in-mould) label can improve the barrier properties of the container against oxygen, water vapor or resistance to aggressive filling goods.
  • the wall-side (in-mold) label can be connected as a whole (peelable) to the inside of the peripheral side wall and the bottom-side in-mould label can be detachable (peelable) as a whole to the inside of the bottom or to the peripheral side wall be connected, so that the (in-mold) label act in the manner of a detachable and true-to-contour inner shell.
  • the (in-mould) labels can be completely separated from the latter by being actively detached or pulled off the container by an operator. In this way, the plastic material of the container, to which filling material typically no longer adheres in this case, can be recycled more easily, or the container can be refilled with filling material.
  • the object of the invention is to provide a bucket and a container with an inner shell that is as true to the contour as possible and that can be easily inserted into the bucket and removed from the bucket again.
  • this object is achieved by a bucket of the type mentioned at the outset, which has at least one dimensionally stable annular attachment which is detachably connected to the peripheral edge, the attachment having a flange section which covers the gripping area, and the attachment an inner shell with a shell base and a peripheral shell wall is attached, the shell base and/or the peripheral shell wall being formed entirely or partially from a film.
  • dimensionally stable is understood in the context of this application to mean that a component, for example the ring-shaped attachment, does not change its shape during normal use and can at most be deformed elastically without considerable effort.
  • a component designed as a film is significantly thinner.
  • the thickness of the base of the shell and the surrounding wall of the shell are generally more than approximately 50 ⁇ m and less than approximately 300 ⁇ m.
  • the case bottom and the Circumferential shell wall - if they are completely formed as a film - are flexible, ie they are not dimensionally stable components.
  • the attachment has an upper clamping profile for cooperating with a clamping profile formed on an inner side of an edge of the lid or on an inner side of another rigid annular attachment.
  • the upper clamping profile of the attachment makes it possible, as with a conventional bucket, to close the opening on the bucket with a latching and sealing lid, with the bucket also being able to be opened and closed 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, more precisely from the inner shell.
  • the attachment has a lower clamping profile in the flange section, which is designed to cooperate with a clamping profile on the engagement area of the peripheral rim of the bucket.
  • the lower clamping profile typically corresponds to a clamping profile formed on the inside of the lid to cooperate with the engagement portion of the peripheral rim.
  • the attachment can be placed on the peripheral edge of the bucket in the manner of a lid and fixed there (locking).
  • a sealing effect on the peripheral edge of the peripheral side wall is not absolutely necessary or not wanted for the attachment (see below).
  • the lower clamping profile can also be used to interact with an upper clamping profile of another, identical attachment in order to stack several attachments on top of each other (see above).
  • the clamping profile on the engagement area or the upper clamping profile of the flange section 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 or on the underside of a flange section of another attachment , or the other way around. It goes without saying that the clamping profile of the gripping area, the clamping profile on the flange section of the attachment and the clamping profile of the lid can also be designed in a different way.
  • the fastening section can be connected to the attachment, more precisely to the side wall section of the attachment, in different ways.
  • a non-detachable connection can be produced by plastic welding or by overmoulding the casing wall with the plastic material of the attachment in an injection molding process during production of the attachment.
  • the film casing wall is detachably connected to the attachment, in particular in a peelable detachable manner, the plastic material of the film casing wall is not compatible with the plastic material of the attachment, so that when the connection is made there is no common melt -Composite formed becomes.
  • the detachable connection of the casing wall of the inner casing to the side wall section of the rigid attachment is advantageous, since in this case the peripheral casing wall together with the casing base and the attachment can be disposed of or recycled separately after the bucket has been used.
  • the casing wall it is possible to connect the casing wall to the inside or to the outside of the side wall section of the attachment. As a rule, it is favorable if the casing wall is connected to the inside of the side wall section of the attachment, since in this case it can usually be avoided that the filling material comes into contact with the side wall section (see below). If the casing wall is releasably connected to the attachment in the fastening section, the attachment can be reused in this case, if necessary.
  • the attachment section of the casing wall extends on the inside of the attachment, preferably on the inside of the side wall section of the attachment, up to a contact area with the cover.
  • the inside of the fastening portion of the film envelope wall comes into contact with the inside of the lid.
  • 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 is the If the lid itself is made of a food-compliant material, the corresponding container as a whole can be food-compliant, even if the plastic material of the dimensionally stable peripheral attachment itself is not food-compliant, for example because the plastic material of the attachment is made entirely or partially from a non-food-compliant regenerated plastic is formed.
  • the bottom of the casing forms a first film and the casing wall forms a second film, which are connected to one another in an overlapping area in a fixed or detachable manner, in particular so that they can be peeled off.
  • the base of the casing and the casing wall of the inner casing can form a joint molded film part, which is typically produced by deep-drawing.
  • the casing wall has a comparatively large height, production by deep drawing may not be possible without further ado. Accordingly, it is favorable if the casing base and the circumferential casing 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, inner shells with comparatively large dimensions can also be produced.
  • the casing base has a section which extends along the casing wall and which, in the overlapping region, overlaps with the surrounding casing wall, preferably with an outside of the casing wall. It has proven advantageous if the overlapping area is formed at the lower end of the casing wall. In this way, the case bottom can be formed as a flat film, whose circumferential edge is folded over or folded in order to be connected to the casing wall in the overlapping area. Since the section that extends along the wall of the casing may have incisions, depending on the geometry of the bucket, it is advantageous to connect the section that extends along the wall of the casing to the outside of the wall of the casing.
  • the protruding section can alternatively overlap in the overlapping area with the inside of the casing wall.
  • the connection can be made by plastic welding or in some other way.
  • the area of overlap typically extends along the casing wall for a height of about 5-15 mm.
  • two edges of the peripheral casing wall lying opposite one another in the peripheral direction are connected to one another in a fixed or detachable manner, in particular in a peelable detachable manner, at an overlapping seam.
  • the foil casing wall can be produced from a flat foil, ie from a flat foil blank.
  • the two edges can, for example, be welded together along the overlapping seam.
  • the connection can be permanent or detachable, in particular detachable in a peelable manner. This simplifies the disposal of the film casing wall. The latter is typically only favorable in the event that the filling material is solid, for example if the filling material is frozen.
  • the bucket comprises a dimensionally stable support ring, which surrounds a lower end of the casing wall and preferably an area of the casing base adjoining the casing wall, and which can be attached in a fixed or detachable manner, in particular peelably detachable, to the outside of the casing wall and/or to the outside of the Case floor is connected.
  • the rigid support ring stabilizes the inner shell at the lower end of the shell wall.
  • the dimensionally stable support ring can be used in particular to cover the overlapping area at the lower end of the casing wall.
  • the rigid support ring can be connected firmly or detachably to the outside of the side wall and/or to the outside or underside of the casing bottom.
  • the rigid bottom area can be attached to the outside of the casing bottom within the rigid support ring, which is connected to the outside of the casing bottom, or the rigid bottom area also covers the casing bottom in the area of the rigid support ring and the rigid support ring partially covers the floor area.
  • At least one carrying aid is attached to the attachment, in particular in the flange section.
  • the carrying aid can be, for example, a carrying handle that is fastened to the attachment at two mounting points or possibly more than two mounting points.
  • the carrying aid can also be a band-shaped carrying handle that is molded onto the attachment.
  • the carrying aid can also be (at least) one carrying handle or the like, which makes it easier for an operator to lift the attachment off the peripheral edge of the bucket and, if necessary, to separate it from it.
  • Such a carrying handle can, for example, have access openings for an operator, which makes it easier to lift the attachment.
  • the peripheral edge has a section that protrudes beyond the peripheral side wall, on which the engagement area is formed, and the protruding section is adjoined by a peripheral apron that is spaced apart from the peripheral side wall.
  • the peripheral edge typically has the engagement area with a clamping profile for cooperating with a clamping profile on an inner side of an edge of the lid.
  • the rim of the bucket forms a double rim which has a section which protrudes radially outwards beyond the peripheral side wall and which is adjoined by the apron which is spaced apart from the peripheral side wall.
  • the skirt typically extends just below the engagement area for securing the lid formed on the overhanging portion of the peripheral rim.
  • Reinforcement ribs are usually provided to stiffen the apron, which extend from the outside of the peripheral side wall to the inside of the skirt.
  • the bucket can have an opening aid, e.g. 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 attachment can have an opening aid, for example an opening tab or the like, in order to make it easier to lift the lid off the attachment.
  • the opening tab which is attached to the peripheral edge of the bucket, the attachment can in principle be detached from the peripheral edge, but not the lid from the attachment.
  • the attachment has an apron section which is adjacent to the flange area and covers the apron.
  • the apron section it is possible to prevent the peripheral edge of the bucket, more precisely the apron, from becoming dirty when liquid filling material is poured out of the bucket. Since the filling material is stored in a filling volume in the inner shell and ideally does not come into contact with the apron or the peripheral edge of the bucket when the filling material is emptied due to the apron section, the bucket can be reused after removing the attachment, if necessary without cleaning , for example by placing a new attachment with an inner shell on top of it or by filling the bucket directly with a product.
  • the apron section can extend in the circumferential direction along the entire apron in order to protect it from the filling material. In order to save material, however, it is favorable if the apron section only extends along a section of the circumference of the peripheral apron in which the filling material is poured out of the bucket.
  • the two sections along the circumference of the bucket, at which the contents can be poured out, are typically located essentially in the middle between the two mounting points of the carrying handle. In the event that the skirt portion only extends over part of the circumference of the peripheral rim or skirt, a suitable orientation of the attachment relative to the peripheral edge of the bucket is required.
  • Such an alignment can be implemented, for example, by an indexing element on the attachment, which enables alignment relative to the mounting points.
  • the carrying aid described above can be designed for this purpose in such a way that it interacts with the mounting point of the carrying handle in such a way that the attachment cannot be rotated in the circumferential direction relative to the peripheral edge of the side wall.
  • the liner wall of the inner liner extends along the peripheral side wall to the bottom of the bucket.
  • the inner shell practically completely fills the filling space volume available in the bucket.
  • the bucket can usually be reused because it does not come into contact with the contents.
  • the attachment can be removed and replaced by another attachment whose inner casing can be filled again with a filling material.
  • the shell wall of the inner shell of the attachment has a height that is less than the height of the peripheral side wall and is preferably less than 90% and preferably more than 10% of the height of the peripheral side wall.
  • the height of the peripheral side wall is measured along the vertical axis of the bucket from the bottom to the top of the peripheral rim.
  • the height of the envelope wall is measured appropriately from the envelope bottom to the end of the attachment portion where the envelope wall is attached to the attachment. The height of the shell wall depends on the particular application.
  • the inner shell typically does not serve to protect the bucket from contamination, but has a different function.
  • the attachment with the inner shell can be used to store a product that is accommodated in the inner shell. This can be useful, for example, if the bucket contains another filling and the two fillings are to be mixed with one another in the inner volume of the bucket.

  • the respective shell bottoms of the attachment and of the further attachment can be pierced with a suitable tool in order to mix the contents. It goes without saying that more than two attachments with more than two inner casings and contents stored therein can also be placed on the bucket.
  • a further application of the attachment described here is to fill the headspace volume of the inner volume of the bucket that is not filled with a filling material, as a result of which oxygen is displaced from the headspace volume and cannot react with the filling material.

  • Reinforcing ribs 35 which extend from the outside of the peripheral side wall 5 to the apron 33 , serve to reinforce the apron 33 .
  • the apron section 32 of the attachment 9 covers the apron 33 in the direction of the vertical axis of the bucket 2 completely.
  • the apron section 32 is limited to an angular range of approximately 30°-40° in the circumferential direction of the bucket 2 . It goes without saying that the apron section 32 can also extend over a larger angular range or run along the entire circumference of the attachment 9 .
  • the skirt section 32 is interrupted in the circumferential direction in an area in which an opening tab 36 is attached to the skirt 23 .
  • the opening tab 36 extends upward into the engagement area 8 of the peripheral edge 6 .
  • the opening tab 36 is pivoted outwards by an operator in order to lift or release the attachment 4 .
  • the apron section 32 provided that it runs all the way around in the circumferential direction, can have a detachable area in the area of the opening flap 36, which can be attached to the remaining protection section 32 via predetermined breaking points, more precisely via a perforation is connected.
  • the attachment 9 can also have an opening tab which extends downward from the flange portion 10 of the attachment 9 to be gripped or pivoted by an operator.
  • the shell wall 13 of the inner shell 11 of the attachment 9 extends along the peripheral side wall 5 to the bottom 4 of the bucket 2.
  • the inner shell 11 described there thus has a filling volume that practically corresponds to the inner volume of the bucket 2.
  • FIG. 5 shows an attachment 9 in which the shell wall 13 of the inner shell 11 does not extend to the bottom 5 of the bucket 2.
  • the shell wall 13 of the inner shell 11 of the attachment 9 extends over a height h in the direction of the vertical axis of the bucket 2, which is smaller than the height H of the peripheral side wall 13 and in the example shown at less than 40% of the height H of the peripheral Side wall 13 is.
  • the height h of the casing wall 13 is adapted to the respective application.
  • a further attachment 9 ′ is placed on the attachment 9 , which has an additional inner sleeve 13 ′ , which protrudes into the inner sleeve 13 of the attachment 9 .
  • the height h of the shell wall 13 of the inner shell 11 is shortened compared to the height H of the peripheral side wall 5 of the bucket 2.
  • the height h of the casing wall 13 is selected such that a filling level 37 of the filling material is slightly higher than the immersion depth of the casing base 12 of the inner casing 11 in the interior volume of the bucket 2.
  • the lid 3 has a valve 39 on its lid surface, which makes it possible to set the overpressure p in the intermediate space 38 so that it can be ensured that the inner shell 11 completely fills the headspace volume of the bucket 2 .
  • FIG. 7 and 8 show a bucket 2 or a container 1 which, in contrast to the bucket 2 or container 1 described above, has an inner shell 13 which is not attached to a dimensionally stable attachment 9 . Rather, the inner shell 13 has a section that protrudes beyond the peripheral edge 6 of the bucket 2 (cf. 7 ), which can be turned inside out and in the inverted state forms a flange section 40 which completely covers the peripheral edge 6 including the apron 33 (cf. 8 ).
  • the inner shell 11 is otherwise formed like the inner shell 11 described above, ie this indicates a 7 and in 8 non-illustrated casing bottom 12 and a casing wall 13 which are connected to each other along an overlapping area 25 .
  • Two recesses 41 are provided on the flange section 40 in the region of the two mounting points 30 of the carrying handle 31 in order to prevent the inner sleeve 11 or the flange section 40 from making it difficult for the carrying handle 31 to pivot.
