Definitions

• the invention relates to a removable and reclosable foil lid for closing the mouth opening of a container.
• Foil lids are commonly used for closing containers, which for example contains food stuffs, such as milk powder.
• the foil lid provides a secure closure of the container and is easily removable from the container.
• the only problem with foil lids according to the state of the art is that such foil lids cannot be used for reclosing the container. It is common to provide an additional cap, which can be placed over the mouth opening of the container and which is used for reclosing the container after the foil lid has been removed.
• a reclosable foil lid comprising:
• attachment means provide the possibility to reattach the foil sheet onto the container providing a reclosable foil lid.
• the attachment means comprise a flexible lip extending at least partially along the periphery of the foil sheet. The lip is formed on the foil sheet and shaped such that the lip forms the reclosable attachment of the foil lid to the mouth opening. This flexible lip will engage onto the edge of the mouth opening and provides an additional attachment of the foil lid to the mouth opening.
• the flexible lip snappingly coacts with the edge of the mouth opening. This provides for a firm attachment of the foil sheet to the container.
• the flexible lip is of a plastic. This provides some stiffness to the flexible lip and ensures that the shape of the lip will stay adapted to the shape of the mouth opening.
• the foil sheet is of a metal, in particular aluminum. This has the dimension to wrinkle and in combination with a plastic flexible lip, the foil sheet will stay less wrinkled even after a number of reclosing actions.
• the plastic flexible lip may be a preformed lip attached such as by adhesive to the foil sheet. It may have the form of a closed or interrupted lip, preferably the form is annular such as circular. Preferably the lip is formed onto the foil sheet by moulding, such as injection moulding. With all embodiments a good closure is obtained.
• the invention further relates to a combination of a container and a reclosable foil lid according to the invention, wherein the container comprises a bottom, a peripheral wall extending from the bottom, wherein the upper part of the peripheral wall defines a mouth opening and wherein the reclosable foil lid is attached to the edge of the mouth opening.
• a part of the peripheral wall comprises an inwardly extending ring-shaped edge.
• the foil lid can be attached in a common way for example by adhering the foil sheet to the ring.
• the edge of the mouth opening comprises a peripheral groove in which the attachment means reclosably engage.
• the groove is formed by a beaded edge. It is common to provide the edge of the mouth opening with a beaded edge. This is to prevent that the sharp edge of the material of the container defines the edge opening. By providing a beaded edge a more rounded edge is provided. Now by suitably arranging the beaded edge, a groove can also be provided into this edge.
• the groove is formed by a bend back portion of the edge of the mouth opening.
• the foil lid is attached to the edge of the mouth opening on either side of the groove.
• the foil lid is adhered to the edge of the mouth opening.
• the container is preferably made by a process, wherein first, the flexible lip is adhered, preferably by sealing to the foil sheet. Second, the foil sheet is adhered to the ring and finally seaming the ring to the container.
• Figure 1 shows a cross-sectional view of a first embodiment of a combination according to the invention.
• Figure 2 shows a cross-sectional view of a second embodiment of a combination according to the invention.
• Figure 3 shows a cross-sectional view of a third embodiment of a combination according to the invention.
• FIG 1 a cross-sectional view of a combination 1 according to the invention is shown.
• This combination 1 comprises a container with a peripheral wall 2 and a ring- shaped upper part 3, which is beaded to the peripheral wall 2.
• the inner edge 4 of the ring-like part 3 is curled, such that no sharp edges define the mouth opening of the container.
• On top of the ring-like part 3 a foil lid 5 is arranged, which has on the bottom side a coating 6 for adhering to the ring-like part 3.
• the reclosable foil lid 5 comprises a lip 7, which extends along the periphery of the edge 4 of the mouth opening.
• the lip 7 partially envelopes this edge 4.
• the foil lid can be reclosed by the flexible lip 7.
• FIG. 2 shows a cross-sectional view of a second embodiment 10 according to the invention. Parts similar to the embodiment 1 according to figure 1 are designated with the same reference signs.
• the combination 10 according to figure 2 has again a ring-like part 3 which is arranged to the peripheral wall 2 of the container.
• the edge 11 again has a curled edge, but in this embodiment provides a groove 12 in which a lip 13 of the foil lid 5 extends. This lip 13 has a notch, which hooks into the curled edge 11 providing a snapping closure for the foil lid 5.
• FIG. 3 shows a third embodiment 20 according to the invention. Again parts similar to the embodiment according to figure 1 are designated with the same reference signs.
• the container has a peripheral wall 2 onto which a ring-shaped part 21 is arranged.
• This ring-shaped part 21 has a curled edge 22, which defines the mouth opening.
• the ring-like part 21 has a bend back portion 23 defining a groove.
• a lip 24 extends, which is attached to the foil lid 5. Again this groove and lip 24 provide a reclosable foil lid.
• the foil lid 5 can be adhered on either side of the groove 23 at the interfaces 25 and 26 between the foil lid 5 and the ring-like portion 21.
