JPH10236474A - Opening structure of drinking aperture in beverage can - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily raise up a ring tap even by a lady having long nails or a child having no strong fingers, by appropriately bending upward the pressing part of a pulltab of a drink can and appropriately denting the top plate face positioned at the lower part of the pressing part of the pulltab to form a recess. SOLUTION: In the opening structure 1 of the drinking aperture, the pressing part 2c of a pulltab 2 constituted of a ring tab 2b integrally fixed on the top plate T of the upper part of a beverage can K by a rivet 2a and the pressing part 2c is bent upward by about 10 degrees (angle D). The ring tab 2b swings up on the rivet 2a by pushing the pressing part 2c of the pulltab 2 with fingers. The cutting-off part of the top plate T is pushed down at the pressing part 2c and the cutting-off part is opened by inserting a finger into the raised ring tab 2b and pulling up it. In this way, the cutting-off part can be easily opened and the ring tab can be easily raised even by women or children having no strong fingers.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drinking can opening mechanism for a drinking can which can be easily opened even by a woman with long nails or a child who does not have strong fingers.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional drinking can opening mechanism in a drinking can has a small gap C between a top plate B and a pull tab A, so that a woman with long nails or a finger has no force. At present, children are having difficulty in opening the ring tab A1 with their fingers not entering, and in some cases, nails may be cracked or broken when trying to forcibly open the ring tab A1. In addition, a coin or the like is inserted into the gap C to raise the ring tab A1, but if there is no coin, there is no other choice but to rely on another method.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the conventional problems, and enables a woman with long nails or a child who does not have strong fingers to easily raise a ring tab of a pull tab. It is intended to provide a drinking can opening mechanism in a drinking can that can open a drinking mouth.

[0004]

As a means for achieving the above object, a pressing portion of a pull tab of a drinking can is appropriately bent upward. Further, the top plate surface located below the pressing portion of the horizontally formed pull tab of the drinking can is appropriately recessed to form a recess.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. The drinking opening mechanism 1 pushes the pressing portion 2c of the pull tab 2 composed of a ring tab 2b and a pressing portion 2c integrally provided with a rivet 2a on a top plate T provided on the upper portion of the drinking can K upward. It is formed by bending about 10 degrees (angle D).

As an example of use of the drinking opening mechanism 1 of the above embodiment, when the finger Y presses the pressing portion 2c of the pull tab 2, the ring tab 2b is raised with the rivet 2a as a fulcrum. Subsequently, by hooking a finger (not shown) on the raised ring tab 2b and pulling it up, the cutout portion T1 of the top plate T is pushed down by the pressing portion 2c, and the cutout portion T1 can be opened.

Next, another embodiment will be described. The mouth opening mechanism 21 is provided with a rivet 22a and a pressing part 22c and a ring tab 22b, which are integrally provided with a rivet 22a, as in the conventional product. The recess 3a is formed by denting the periphery of the cutout 3a1 of the plate 3. The depth H of the recess 3a is about 3 mm.

As an example of use of this embodiment, by pressing the pressing portion 22c of the pull tab 22 with the finger Y1, the pressing portion 22c enters the recess 3a with the rivet 22a as a fulcrum, and at the same time, the ring tab 22b rises. Then,
By hooking a finger (not shown) on the raised ring tab 22b and pulling it up, the cutout portion 3a1 in the concave portion 3a can be pressed down by the pressing portion 22c to open the cutout portion 3a1.

In each of the above embodiments, details may be changed as long as they perform the same movement.

[0010]

【The invention's effect】

1). Women with long nails and children with weak fingers can easily raise the ring tab. 2). The cutout can be easily opened.
