Reclosable Foil Lid

Abstract

A reclosable foil lid (5) for closing the mouth opening of a container, said lid comprising: a foil sheet adapted to the mouth opening of the container; and attachment means arranged to the foil sheet for reclosable attachment to the edge of the mouth opening. The invention furthermore relates to combination of a container and a reclosable foil lid according to any of the preceding claims, wherein the container comprises a bottom, a peripheral wall (2) 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.

Description

These and other features of the invention will be elucidated in conjunction with the accompanying drawings.

FIG. 1 shows a cross-sectional view of a first embodiment of a combination according to the invention.

FIG. 2 shows a cross-sectional view of a second embodiment of a combination according to the invention.

FIG. 3 shows a cross-sectional view of a third embodiment of a combination according to the invention.

In 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. Of the lid 5 has been removed from the ring-like part 3 by pulling the tab 8 the foil lid can be reclosed by the flexible lip 7.

When such a combination 1 is being sterilized, the lip 7 provides some relief for the attachment of the foil lid 5 onto the ring-like part 3. Due to the shape of the lip 7 part of the pressure is transferred to the edge 4 thereby reducing the forces on the attachment zone of the attachment of the foil lid 5 onto the ring-like part 3.

FIG. 2 shows a cross-sectional view of a second embodiment 10 according to the invention. Parts similar to the embodiment 1 according to FIG. 1 are designated with the same reference signs.

The combination 10 according to FIG. 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 FIG. 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. In this 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.
