[0035] Best Mode for Carrying Out the Invention

[0036]As shown in the accompanying drawings, the tab 30 provided on the can lid of the present invention has a free end portion, or first end portion 31, on which a user's finger force is applied when the can lid is to be opened. end part. A hole 34 is formed at the center of the end portion 31, and a rivet hole is formed at the fixed end or second end portion of the pull ring 30, and the pull ring 30 is fixed on the can lid with the rivet 24 at the rivet hole. Such as Figures 1a to 1r As shown, a groove-shaped concave line portion 38 is formed on the pull ring 30 near the first end portion 31 . The central portion of the ring 30 between the hole 34 and the second end portion may be provided with a finger push member 36 having a variety of shapes so that the user can more easily depress the pull ring 30 . According to other improvements of the first embodiment of the present invention, such as Figures 2a to 2z As shown, a...

Abstract

A can lid structure, with an opening tab providing improved practicability, enhanced opening function and improved sanitariness, is disclosed. This can lid structure is preferably used with easy open cans with one-touch type opening means, or with a so-called 'stay-on tab'. In the above can lid structure, an opening tab (30), locked to a can lid using a rivet (24), is levered up by a user so as to break the seal of an opening piece (22) along a depressed seam (21) on the can lid when it is necessary to open the lid prior to emptying a can. In order to open the can lid, the free end portion (31) of the tab (30) is primarily raised up from the top surface (20) of the can lid while forming an appropriate gap between the tab (30) and the can lid by pressing the tab (30) downwardly by a finger. The tab (30) is, thereafter, levered up to break the seal of the opening piece (22) along the depressed seam (21). The above object is accomplished by a thumb pushing part (36), a thumb-operable resilient bulge (33), and / or a depressed linear portion (38) in the form of a groove, respectively formed on predetermined positions of the tab (30). This can lid structure thus accomplishes a desired sanitariness, operational convenience and operational reliability of cans (10).

Description

technical field [0001] The present invention relates generally to lid construction for pop cans with a one-touch opening device, or with a so-called "fixing ring", and more particularly to a lid construction for such a can that is designed to so that the outer end of the tab can be easily lifted from the upper surface of the can lid by a downward motion of the fingers so that a suitable gap is first created between the ring and the can lid before the ring is pulled open to open the can lid at the opening tab , finger push pieces, elastic protrusions and / or grooves that can be operated by fingers are provided at the predetermined positions of the ring, so that the user can easily move from The jar lid lifts up the end of the ring. Background technique [0002] Such as figure 1 As shown, several can lids with a tab 30 designed to easily open the seal of the flap 22 on the can 10 along a recess have been proposed and used. For example, a conventional pull tab is designed to ...
