Abstract
A reclosable can lid is described that has a collar part and a lid receiving part composed of plastic that can be coupled to one another via a snap-in latching connection, wherein a tear line closed in itself is either partly perforated or is formed as a toothed separating line and the leak-tightness is ensured by a sealing film provided at the inner side of the lid cover.
Claims20
A can lid having a sealingly reclosable opening, the can lid comprising a bounded opening region provided in a metallic lid material of a lid surface as well as a two-armed lifting member intended to open this opening region,
- said lifting member being connected to a pull tab on the one hand, and engaging at the opening region of the lid surface, on the other hand, and being supported via a bearing translating the opening force applied to the pull tab;
- wherein the opening region is configured as a closure lid and is connected at its outer margin in a force-transmitting manner to a collar part composed of a plastic material, and wherein a lid receiving part that is connected in a force-transmitting manner to the lid surface outside the opening region and that is composed of a plastic material is associated with the collar part;
- wherein the collar part furthermore engages over the lid receiving part and a sealing snap-in latching connection having at least one peripheral coupling rib and a cut-out shaped in complementary form thereto is formed between the collar part and the lid receiving part;
- and
- wherein the pull tab is fastened radially outside the lid receiving part to a fixing region of the collar part and the two-armed lever for opening the opening region is formed at a partial peripheral region of the collar part associated with the fixing region;
- and
- wherein the lower side of the metallic lid is coated and this coating is attenuated or thinner surrounding the opening region,
- wherein the collar part and the lid receiving part each have a plurality of molded noses arranged distributed in an annular manner;
- wherein these noses extend through adapted openings in the metallic lid part;
- and wherein the collar part and the lid receiving part are connected to the metallic lid part in a shape-matched and force-transmitting manner as well as sealingly by a rivet-like deformation of the noses under the effect of heat while interposing an adhesive promoting layer.

A can lid
- having a snap-in latching connection between a collar part and a lid receiving part, wherein the snap-in latching connection comprises a coupling and sealing rib that is provided at the lid receiving part and that engages into a first adapted recess in the collar part and comprises a preloading and latching lip that latchingly engages into a second recess of the collar part and presses a wall rib between the first adapted recess and the second recess toward the coupling and sealing rib.
A can lid having a sealingly reclosable opening,
- the can lid comprising a bounded opening region provided in a metallic lid material of a lid surface as well as a two-armed lifting member intended to open this opening region,
- said lifting member being connected to a pull tab, on the one hand, and engaging at the opening region of the lid surface, on the other hand, and being supported via a bearing translating the opening force applied to the pull tab;
- wherein the opening region is configured as a closure lid and is connected at its outer margin in a force-transmitting manner to a collar part composed of a plastic material, and wherein a lid receiving part that is connected in a force-transmitting manner to the lid surface outside the opening region and that is composed of a plastic material is associated with the collar part;
- wherein the collar part furthermore engages over the lid receiving part and a sealing snap-in latching connection having at least one peripheral coupling rib and a cut-out shaped in complementary form thereto is formed between the collar part and the lid receiving part;
- and
- wherein the opening region of the can lid is separated from a fixed outer lid surface surrounding it by one of a cutting process and a punching process, and
- wherein the two initially separated parts are again joined to one another in a shape-matched manner such that the two parts practically become one part again that can be handled as a single part and wherein the lower side of the can lid is coated and this coating is attenuated or thinner surrounding the opening region.
