Description

Canned can opener {CAN OPENER}

The present invention relates to canned can openers that can be opened easily by cutting the edge of a canned can after puncturing or adsorbing the canned can top portion.

As is well known, a one-touch can is used which has an opener for opening a lid having a cut-out at its edge to use or consume contents stored in a metal can.

When the one-touch can is opened, the user can open the can by grasping the can with one hand and pulling the one-touch can with the finger of the other hand. Conventionally, the can around the can is cut Provides superior convenience compared to the method of opening.

That is, when the lid of the one-touch can is opened, if the lid is lifted up with the fingers, the lid is formed with a breaking hole, and then the lid is continuously lifted to break the cut edge of the lid from the breaking hole. .

However, the incision for opening the one-touch can is not easily cut unless a force of a certain size or more is applied to the structure of the contents of the can, and a considerable amount of force is required when pulling the can opener with fingers. There is a problem that the user may be injured by the carelessness of the user when the lid is opened or the lid is opened or the user does not give a constant and accurate force to the opener.

In recent years, attention has been paid to these points, and research has been conducted on cans equipped with a body protection band or an assisting plate during the production of one-touch cans. However, in the case of attaching a can- There is a problem that foreign substances are caught in the manufacturing process of the can, or the manufacturing cost of the can is increased.
