Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pull tab of a pull-tab can, and more particularly, to a recess having a moderate depth, which facilitates operation of the pull-tab and allows a fingertip to be easily inserted into a gap between the tip of the pull-tab can and the upper lid. The present invention relates to a pull-tab can which is provided on an upper lid to facilitate opening and is excellent in safety.

[0002]

2. Description of the Related Art A conventional pull-tab can uses a pull-tab having a slightly raised end of a flat pull-tab at the top lid of a can body, and a shallow recess provided in a gap between the tip and the upper lid. .

[0003]

SUMMARY OF THE INVENTION The recess of the prior art is
It is difficult to insert the fingertip because the nail of the fingertip is only deep enough to get in, the fingertip hurts, or the nail polish is peeled off, so you may lift the pull tab with the principle of leverage using coins and open the can. This method has the disadvantage that the edges of the can are unsanitary.

[0004] The above-mentioned disadvantages are caused by other known materials such as US Pat. No. 5,224,618 and US Pat.
No. 729 also points out a similar problem from general consumers.

[0005] Further, in the case of a fully open type in which the entire upper lid is detached, raising the pull tab may cause a problem.
The problem is that considerable power is required and the can is thin, so it is difficult to hold it with one hand, and the contents of the can are easily spilled, so that the sharp edge of the top lid may cut your hand accidentally, which is very dangerous. there were.

[0006]

According to the first aspect of the present invention, a pull tab formed in a required shape on an upper lid of a can body and rotatable in an arbitrary direction about a caulking portion is provided. In the gap between the tip of the pull tab and the upper lid, a concave portion with a depth that allows fingertips to be easily inserted is provided in the upper lid, making opening of the can easy and safe, and does not impair the lamination storage and supply of the upper lid in the manufacturing process , And pull-tab cans.

Further, what is described in claim 2 is a pull tab slidable by providing a vertically long hole and a slide groove in the upper lid.

[0008]

An embodiment of the present invention is formed as described above.
When the invention is used, a fingertip is inserted into the first concave portion having an appropriate depth provided in the upper lid of the pull tab tip, and the pull tab is grasped and pulled up. Can be opened safely and easily.

In the upper lid of the present invention, long grooves are provided on both sides of the concave portion, and the position of the pull tab can be easily changed to a required portion with the caulking portion as an axis. Do not interfere with each other, and can keep a large number of upper lids in a normal stacking position.

Further, in the case of using the second aspect, it is possible to open the can safely and easily by grasping the tip of the pull tab stopped at the edge of the second concave portion, pulling it out to a required position of the concave portion, and gently pulling up. .

The upper cover 3 is provided with a vertically long hole 7A on one side, and a pull tab 2 slidable by a projection 8 is provided. A second concave portion 7 and a slide groove 7B are provided in a gap between the tip of the upper cover 3 and the upper lid 3 so that the fingertip F can be easily inserted.

FIG. 4 is an enlarged sectional view taken along the line BB of FIG. 3 with a part thereof omitted. Explanations of reference numerals and functions are the same as those in FIG.

FIG. 5 is a partially enlarged cross-sectional view showing a method for implementing the present invention, which is described in claim 1 of the present invention.
The can is opened by inserting the fingertip F into the gap between the concave portions 4, but since the depth of the first concave portion 4 is appropriate, the operation is easy, reliable, and safe.

FIG. 6 is a plan view showing the shape of the upper lid 3 in the first manufacturing step described in claim 1 of the present invention. The caulking portion 5 is rotated in an arbitrary direction about an axis to change to a required portion. However, since a plurality of stoppers 6 are provided at the same portion, the stopper can be securely fixed to a predetermined portion.

FIG. 7 is manufactured by the method described in FIG.
FIG. 4 is a cross-sectional view of a case where a plurality of upper lids 3 cut along the line C-C are overlapped. Since the upper lids 3 when stacked are brought into contact with each other at the positions of the contact points 9, the first concave portions of the upper and lower upper lids 3 are formed. 4, the many upper lids 3 can be maintained in a normal stacking posture without mutual interference.

FIG. 8 is a plan view showing a method of returning the position of the pull tab 2 to the original position in the final step of filling the contents into the pull tab can described with reference to FIG. Then, the caulking portion 5 is rotated in an arbitrary direction about the axis to return the caulking portion 5 directly above the first recess 4.

FIG. 9 is a plan view showing an operation state of the above-described second embodiment of the present invention. The pull tab 2 which is provided with a vertically long hole 7A and is slidable by a projection 8 is provided. The second recess 7 is held by grasping the tip of the pull tab 2.
And pull it out gently and open the can.
In the lower part to improve the movement of the finger when pulling out,
A slide groove 7B is provided.

FIG. 10 is a cross-sectional view of the prior art. The tip of a pull tab 2 formed in a required shape is slightly lifted in the upper lid 3 of the can body 1 and a shallow recess 10 is formed in a gap between the pull tab 2 and the upper lid 3. Is provided.

The inner shape of the first and second concave portions of the present invention may be any suitable shape such as a circle, an ellipse, a triangle, or other polygons. It is sufficient if the shape is easy and safe.

[0023]

The present invention is embodied in the form described above and has the following effects.

According to the present invention, since the depth of the groove adjacent to the concave portion provided in the upper cover at the tip of the pull tab is appropriate, the fingertip can be easily inserted into the gap with the pull tab, and the tip of the pull tab is securely grasped and pulled up gently. The opening of the pull-tab can is safe and easy.

According to the present invention, in the first manufacturing process of the upper lid, the pull tab is rotated in an arbitrary direction about the swaged portion of the pull tab and fixed at a predetermined position, or the pull tab itself is of a sliding type. The pull tab and the recess do not interfere,
There is also an effect that a number of upper lids can be maintained in a normal stacking posture.
