Description

  The present invention relates to an improvement in a can lid of a canister of a drink can.

Steion tab type can lids are mainly used for drink can can lids, and the rivet fixing part of the tab is a fulcrum by lifting the pulling part at the rear end of the tab fixed by rivets on the upper cover panel of the can. According to the principle of lever, the pressing part at the tip of the tab is pushed down as an action point, the score of the mouthpiece provided in advance on the upper surface of the panel is broken, and the broken mouthpiece is folded inside the can. It is designed to open in a state where
When opening the mouth of such a conventional steion tab type drink can, in order to lift the pulling part at the rear end of the tab, the fingertip must be inserted between the pulling part at the rear end of the tab and the upper lid panel. In other words, this work may be difficult for people with thick fingers or long nails. In addition, even when a finger is inserted, the pulling up of the rear end of the tab is raised, so that the finger becomes painful and it is difficult for a child or a woman with weak power to open it.
Accordingly, various improvements have been tried and proposed for the structure of the steion tab of this type of can lid.

For example, the applicant puts a triangular thin film sheet between the drink canister's steion tab and the top cover panel, and when raising the steion tab, first pick and lift the triangular thin film sheet with the fingertip, Lift up the pulling part at the rear end of the tab and raise the tab until the opening of the can opens, or when the tab is lifted to the extent that the finger hole is at the pulling hole at the rear end of the tab, The structure of the lid can be opened easily by raising the tab to open the opening (Japanese Patent Application Laid-Open No. 11-105869), and using the film sheet for the same purpose, the opening of the can lid A “drink can easily open lid structure” (Japanese Patent Laid-Open No. 11-278484) is disclosed.
The method of using the film sheet as an auxiliary member for raising the tab as described above is suitable for the purpose of easily raising the tab, but in addition to the conventional steon tab, a film sheet must be prepared separately. However, the manufacturing process for inserting this between a tab and an upper cover panel also increased, and there was a problem that the material cost and the manufacturing cost increased.

In addition, the applicant has extended a finger insertion portion for facilitating raising of the pull-up portion with a finger from the pull-up portion at the rear end of the tab, and arranged so as to be positioned in front of the pressing portion of the tab. “Structure of easy opening of tab” (Japanese Patent Laid-Open No. 2000-128167).
This tab structure has a problem that the tab itself is large and is not suitable when the can lid of the drink can is small.
