Problems solved by technology

[0003] However, these well-known can lids have the following disadvantages: for example, once the can lid is opened, it cannot be reclosed, the lid area that initially closes the opening area is damaged during the upward pivoting of the lever member and the can during this process. is pressed into the interior of the can and comes into contact with the liquid during opening, which is hygienically problematic and during opening, i.e. when the weakened groove present in the lid material between the opening area and the lid surface is torn or separated When, tiny substances are inevitably released from the lid material and can enter the interior of the tank

Embodiment Construction

[0036] figure 1 An embodiment of a can end according to the invention is shown in a schematic plan view. Said can end is provided with a bead 2 in the conventional manner in its peripheral area, wherein the area arranged inside the bead 2 is formed by a cover surface 3 having an opening area formed opposite to the Center offset tongue 4. Such a metal can end comprising aluminum material is arranged around the opening area 4 , wherein at least one reinforcement area 14 is formed by deformation of the material.

[0037] The double-arm bars 5 , 6 are connected (in particular riveted or welded) to the tongue 4 of the can lid 1 delimiting the area of ​​the opening so that a fixed connection point 7 is formed. This connection point 7 is arranged in the edge region of the tongue 4 or opening region, ie opposite the tongue base, which is connected to the lid surface 3 and forms a pivot bearing region 9 during opening. The double-arm lever comprises a shorter area and a longer area,...

Abstract

The invention relates to a conventionally-designed can lid (1) particularly intended for drinks cans, characterised in that in order to form an opening that reseals in a liquid-tight manner, a substantially annular plastic moulded part (15) is secured to the underside of the lid surface (3) so as to enclose the opening region (4); a plastic stopper part (16) is rigidly secured to the underside ofthe tongue-tab, which can be pivoted out when opening, said plastic stopper part engaging with the moulded part (15) such that a seal is formed; and the peripheral contour of the tongue-tab (4) is positioned, preferably in the region of the moulded part (15), at a predetermined distance from the stopper part (16).

Description

technical field [0001] The invention relates to a can end, in particular for beverage cans, having a tongue-like opening area which is provided in the metal lid material of the lid surface and is delimited in particular by material weakening, The can lid has a double-armed lever member for opening the opening area, which is fixedly connected to the lid material in the opening area, in particular via a riveted connection or a welded connection, and for opening during opening. Pivot the tongue up. Background technique [0002] Such can ends are used to a great extent all over the world. It can be manufactured simply and cheaply, and allows space-saving stacking of cans, and also allows opening of the cans by simply pivoting the long arm of the lever member upwards. [0003] However, these well-known can lids have the following disadvantages: for example, once the can lid is opened, it cannot be reclosed, the lid area that initially closes the opening area is damaged during t...
