Description

Can Opener {Can Opener}

The present invention relates to a can opener, and more particularly, to a can opener that allows a user to easily open a can lid, enables a stable pivoting operation without slipping the can body from the opener during can opening, The canister by the edge of the lid of the can is related to the can opener which can prevent a safety accident.

The contents can be stored for a long period of time, and cans are widely used because of convenience of storage or handling. Generally, the can lid is provided with a can ring that fingers the fingers so that the can can be easily opened from the outside.

However, when the fingers were inserted between the can ring and the can lid in order to place the fingers on the can loop, the nail was broken or the hand pain was often felt due to the firm connection between the metal can ring and the can lid. In addition, during the process of opening the lid by applying a finger to the lid of the can, often the hand bail accident occurred in the sharp corner of the open lid.

In order to solve this problem, a can opener of Korean Registered Utility Model No. 0430060 and Patent Registration No. 1299672 is proposed as a method of opening a lid of a can without requiring the user's finger to touch the can loop.

The can opener of Registration Practical Utility Model No. 0430060 includes a center portion having a substantially circular shape when viewed from the side and an upper portion formed upwardly from one side of the outer peripheral surface of the central portion so as to be fitted into the can loop, And a knob extending from one side of the outer circumferential surface to the center portion so as to form an obtuse angle with respect to the fitting portion with respect to the center portion.

The process of opening the can lid of the can opener will be described. When the handle is lowered after inserting the fitting portion into the can loop, the central portion of the round rotates to open the can loop. However, the can opener can rotate the handle only at a certain angle from the rotation starting point, and it is difficult to turn the can lid completely by 360 °. Therefore, the can lid can not be completely opened, There is a problem that the volume of the opener is increased as the diameter of the center portion becomes larger in order to be applied to a can lid having a large diameter.

The can opener disclosed in Patent Registration No. 1299672 includes a circular surface portion surrounding an upper portion of a can container and a lower stop portion provided at a lower end of the central portion of the circular surface portion in parallel or inclined with respect to the circular surface portion, And a vertical supporting surface is provided on an inner side of an outer protruding portion of the can container. The vertical supporting surface has a vertical supporting surface on one side of a rear end of the circular surface portion, As shown in FIG. However, the can opener has the following problems.

First, since the user must grasp the circular surface portion to grasp the circular surface portion and use the vertical supporting surface as a lever to rotate the upper portion, there is a problem that the finger is caught at the sharp edge of the lid of the can during the rotation process. The visual field is obscured by the hands of one user, and it is difficult to know how much the can lid is opened and where it is located, thereby increasing the problem of safety accidents.

Second, there is a problem that the can loop which is erected in the vertical direction and inserted into the gap space is often detached during the rotation process.

Third, the user has to open the can lid by 90 ° backward with the wrist backward, and then open the can lid by turning the wrist forward by 90 ° again, thereby giving excessive force to the wrist.
