JP2002173141A - Lid with swell for pushing up tab - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a can lid which solves a problem that when a can for canned food or drink is to be opened, a nail at a finger tip or the like must be hooked in order to pull up a tab from a lid surface, but this is difficult for those with a weak nail at the finger tip or weak force such as a woman, a child, or an aged person in particular while it is more difficult especially to open the lid of the can with a small diameter. SOLUTION: The lid 1 is equipped with a swell 3 for pushing up the tab 2 on a side of a region where the tab 2 is placed. The tab 2 is moved onto the swell 3 with a clamp 4 for attaching the tab 2 as a fulcrum, a gap is made between a surface of the lid 1 and the tab 2 by a principle of a wedge. Thus the tab 2 can be easily pulled up without need of engaging a nail at the finger tip 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tab for mounting a can 1 for cans such as food and drink, and a tab 3 attached to the can lid 1 as means for opening an opening 5 of the can 1. When the tab 2 is raised, the tab 2 is moved over the raised portion 3 so as to be pushed up by the principle of wedge, and a gap between the surface of the lid 1 and the tab 2 is formed, so that the tab 2 is easily raised. It is about doing.

[0002]

2. Description of the Related Art Conventionally, a tab 2 attached to a lid 1 of a can for opening a can 5 for cans for food and drink can be divided into a stay-on tab type and a pull-tab type.
The attached state is designed on the condition that it does not protrude above the surface of the closed top 6 of the lid 1 even if it expands due to an increase in the internal pressure of the can for problems in the sterilization process and the distribution process. . Since both are mounted on the assumption that they do not float on the surface of the lid 1, the gap is small.

The operation of opening the opening 5 of the can is analyzed (see FIG. 2). (A) A gap is formed between the surface of the lid 1 of the can and the tab 2. (B) The tab 2 is raised with the fingertip 8 to open the opening 5. At this time, the tab 2 is raised from the surface of the lid 1 of the can, which is necessary as the first operation in the above (a). Wearing it feels more unpleasant than necessary. This is particularly noticeable when opening the opening of a small-bore drinking water can. In addition, it is troublesome for a woman with a fingernail such as a woman or an elderly person or a person with weak power to search for a substitute, but the first operation of opening the opening 5 is the surface of the can lid 1 and the tab 2. I made a gap and moved to (b).

[0004] In order to make it easy to hook the nail of the fingertip 8 on the tab of the above-mentioned operation (a), the following is performed by each manufacturer. (A) The raised portion of the tab 2 is shortened in order to keep an interval from the inside of the tightened portion of the lid. (B) An object in which a depression is provided on the surface of the lid 1. (C) To raise a gap between the surface of the lid 1 and the tab 2, the raised portion of the tab 2 is slightly bent. If these were not used to raise the tab 2, the tab 2 could not be raised unless the nail of the fingertip 8 was hooked, and only the nail of the fingertip 8 was easily hooked.

[0005]

The opening 5 is attached to the lid of a conventional can for canning food and drink.
The mounting state of the tab 2 has a design condition, there is no gap with the surface of the lid, and when the tab 2 is raised as the first operation to open the opening 5, the nail of the fingertip 8 is always hooked on the tab 2. I have to feel uncomfortable. In addition, as the number of adoption of the stay-on tub method, which is effective for environmental protection, is increasing, even with people with weak finger power, it is possible for each manufacturer to work with research expenses so that the tab 2 can be easily caused. It seems that research is being done by spending prototype costs, but it has not been resolved. The present invention has been invented in order to meet such strong demands of users.

[0006]

The remodeling of the can lid 1 according to the present invention has solved the above-mentioned problems, and the structure of the can is now described. The ridge 3 is simply provided on the lid 1 beside the conventional mounting position of the tab 2.

[0007]

Next, the operation of the present invention will be described. When opening the opening 5 of the lid 1 of a can for canning food and drink. (B) The tab 2 is provided with the caulking portion 4 for attachment as a fulcrum,
To the top of the ridge. (B) The tab 2 is pushed up from the surface of the lid 1 to the height of the protruding portion 3 by the principle of wedge to form a gap. (C) The tab is opened by raising the tab with the fingertip. It is no longer necessary to hook the nails of the fingertip 8 in the related art, the tab 2 can be easily caused by the fingertip 8 without any discomfort, and the opening 5 can be opened without any resistance.

[0008]

FIG. 2 is a sectional view showing a state in which a tab 2 of a conventional can lid 1 is attached and an opening 5 is opened. A state in which the conventional opening 5 is opened will be described. There is a design condition regarding the attachment of the tab 2 attached to the lid 1 of the can for opening, and a state where the gap is attached small in parallel with the surface of the lid,
In order to raise the tab 2, the nail of the fingertip 8 must be hung on the raising part 7 to make a gap, and the gap must be raised. At this time, it is uncomfortable for a man to hook the nail of the fingertip 8 more than necessary. .
In addition, the nails of the fingertips 8 such as female children and the elderly, and those with weak powers, took time to open gaps by searching for substitutes. Especially when opening small cans for beverages,
I feel remarkably.

[0009]

FIG. 1 is a perspective view of the present invention in which a raised portion 3 is provided beside a position where a tab 2 of a can lid 1 is attached. FIG. 3 is a cross-sectional view in which a raised portion 3 is provided on the lid 1 of the can. The tab 2 is moved sideways with a finger by using the caulking portion 4 for mounting the tab as a fulcrum. A state in which the raised portion 3 is pushed up from the surface of the lid 1 to the height of the raised portion 3 with the fulcrum 4 as a fulcrum, a gap is formed in the raised portion 7, and the tab 2 can be easily raised with the fingertip 8. There is no need to hook the nails of the fingertips 8 and there is no discomfort. Women and children can easily raise the tab 2, and the tip of the tab is centered on the caulking 4 at the base of the opening 5. It is shifted in the opposite direction, but there is no problem with the opening.
There is no problem with the mounting method as before.

[0010]

By using the can lid 1 provided with the raised portion 3 according to the present invention, the claw of the fingertip 8 is hooked on the tab when the opening 5 of the can for canning food and drink is opened. There is no need and there is no discomfort to hook nails. In addition, conventional tab 2
In order to make the hook of the fingertip 8 easy to catch by the mounting method of the above, to raise the space between the inside of the tightening portion 6 of the can lid 1 and the mounting position of the tab 2, the raising portion 7 is formed on the principle of leverage. On the contrary, the opening 5 of the lid 1 was required to be pressed to break it. This problem is also prevented from being unnecessarily separated from the inside of the winding portion 6 of the can lid 1, and the raising portion 7 of the tab 2 is not removed.
Can be made longer than before, by the principle of leverage,
The force for pushing through the opening 5 becomes smaller than before, and the opening 5 can be pushed easily. The nail 5 of the fingertip 8, a weak female child or an elderly person can easily open the opening 5 without any resistance. The present invention has solved the problem in such a simple manner.
