Abstract

PURPOSE:To easily insert a finger into a tab hole by bending the tab by approximately 180 degrees at a predetermined position between a finger hole and a hole for attaching the tab to a can lid in a direction toward the latter hole. CONSTITUTION:A hole 2 for attaching a tab to a can lid 1 and a finger hole 4 are made on a body 3 of the same tab. The finger hole 4 on the tab body 3 is formed with a sufficient size for insertion of a finger, and at a predetermined position 5 between the finger hole 4 and the hole 2 for attaching the tab body 3 to the can lid, the tab body 3 is bent by approximately 180 degrees in a direction toward the hole 2. At this time a radius of curvature at a bent part of the tab body 3 is determined appropriately so that the tab body 3 may not be broken at the bent part even if an end of the finger hole 4 on the bent tab body 3 is pulled to stand. Thus a finger can be easily inserted into the finger hole 4, thereby facilitating opening.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for holding a drinking water such as juice or beer or a can for holding food or favorite foods, etc. Belongs to the field of tabs.

[0002]

2. Description of the Related Art Conventional pull-open tabs used to open the lid of a container, such as a container containing drinking water such as juice or beer or a can of food or food , To protect the living environment, some tabs and chips from the lid of the can do not separate from the lid of the can after opening the lid of the can. In such a can, the tab's finger hole part and the surface of the lid of the can are mounted close to each other so that the finger hole part of the tab is close to the surface of the lid of the can.

Also, when opening the can lid, even if a finger is inserted into the finger hole of the tab and the tab is pulled upward, the tab does not bend, so that a predetermined cut on the can lid can be easily torn open. The strength of the tab is strengthened by folding back around the tab or thickening the thickness of the tab.

Furthermore, the lid of a can containing beer or the like has a small diameter, and since the horizontal distance between the edge of the lid and the finger hole of the tab is short, the tab must be shortened unless the tab length is shortened. Does not fit in place and the tab length is unavoidably shortened. As a result, the size of the finger hole is so small that a person's fingertip cannot be fully inserted. One example is a finger hole with a minor axis of only 6.8 mm.

[0005]

[Problems to be Solved by the Invention] In the conventional pull-open type cans as described above, since the vertical gap between the tab and the can lid is narrow and the tab is firmly fixed, When opening, it is difficult to hang the tab by pulling it on the tab and sometimes it is not possible to lift the tab with only the finger, and after lifting the tab end with a hard object such as wood or metal, put the finger into the hole of the tab You may even have to insert the and then pull up the tab to cut open the can lid.

[0006] Also, the lid of a can containing beer or the like has a small diameter, and the distance between the edge of the lid and the finger hole of the tab is short, so that it is not possible to put a finger on the tab sufficiently. Also, because the distance between the edge of the lid and the finger hole of the tab is short, the length of the tab must be shortened so that it cannot fit in place, and the length of the tab must be shortened as a result. The finger holes are restricted and the size of the finger holes becomes smaller. There is also a drawback that the finger holes are too small to insert the fingers into the finger holes sufficiently.

Therefore, the problem to be solved by the present invention is to form a tab which allows a finger to be easily inserted into the hole of the tab when opening the can lid even if the can lid is small.

[0008]

One means of the present invention is, as shown in FIG. 1, a: a hole (2) for attaching a tab to a lid (1) of a can.
And the finger hole (4) in the same tab body (3), b: the finger hole (4) of the tab is large enough to insert a finger, and c: the finger hole (4) , In place (5) between the holes (2) for attaching the tabs to the lid of the can, in the direction of the holes (2) drilled for attaching the tabs to the lid of the can (3).
Bend about 180 degrees, and d: Determine the length of the radius of curvature of the bent part of the tab so that the bent part of the tab will not be broken even if it causes the end of the finger hole of the bent tab.

As an application example of the present invention, another means is, as shown in FIG. 2, a: the body (3) of the tab and the handle (6) for pulling up the tab.
B): Make the finger hole (4) of the handle large enough to insert a finger, c: Bend both ends (7) and (8) of the handle so that the ends of the handle are on the same line. D): Insert both ends (7) and (8) of the handle into the hinge (5) made integrally with the body of the tab at the end of the body (3), and connect it to the body of the tab (3). Connect the handle (b), e: allow the handle (6) to rotate about the axis (7-8), f: size the handle (6) so that the handle (6) is above the tab body. Make sure the size of the finger hole (4) of the handle overlaps the caulking hole (2) for mounting the tab when you push it down.

As another application example, as shown in FIG. 3, a: the body (3) of the tab and the handle (6) for pulling up the tab.
And b are made separately, b: the finger hole (4) of the handle is made large enough to insert a finger, and c: both ends (7) and (8) of the handle are bent to form a straight line facing each other, d: Ears (9) and (10) on opposite sides of the body of the tab
Bend up and down in a U shape, e: make holes in the folded ears (9) and (10), and f: put the ends (7) and (8) of the handle (6) into the ears. Insert: g: The handle (6) can rotate around (7-8), h: The size of the handle (6) is when the handle (6) is laid down on the body of the tab. , The size of the finger hole (4) of the handle overlaps the caulking hole (2) for mounting the tab.

There are the above three means for solving the problems.

According to claim 4b, it is defined that both ends (7) and (8) of the handle are bent to form a straight line facing each other on the same line, but both ends (7) and (8) of the handle are ears. You may bend the tip of the handle after passing both ends (7) and (8) of the handle through the ear holes so that it will not come out of the hole.

[Operation] Referring to FIG. 1, a: a small protrusion provided at a predetermined position on the can lid (1)
Caulking through the tab mounting holes (2), the tab body (3) is tightly attached to the can lid (1). b: There is a finger hole (4) at one end of the bent tab (3), and the tab has a large finger hole so that the finger can easily enter the finger hole. c: The tab finger hole has a minor axis of 7.0 cm to 25.0.
It is large enough to fit a person's finger in cm. d: A hole (2) drilled to attach the tab to the can lid at a predetermined position (5) between the finger hole (4) and the hole (2) to attach the tab to the can lid. Tabs in the direction of (3)
Is bent about 180 degrees, e: The finger hole (4) of the tab overlaps with the hole (2) for crimping the tab, and f: the radius of curvature for bending the tab at a predetermined position (5) is 0.4 mm to It is 20.0 mm.

To open the can, when the end of the finger hole (4) of the tab is raised, the bent portion (5) extends and the tab becomes L-shaped, and the position of the finger hole (4) is located at the edge of the can. Not only is it higher, but the size of the finger hole is large enough to fit your finger in, so you can insert your finger into the finger hole more easily than with conventional tabs. Then pull the tab up harder and the pull-open can lid will open according to the cut on the can lid.

Generally, a metal plate made of aluminum, iron, or an alloy of aluminum is used as the material of the tab, and the thickness of the metal plate is about 0.4 mm, and the bent portion (5) of the tab (3) is used. The radius of curvature of is larger than the thickness of the metal plate of the tab, so even if you raise the end of the finger hole (4) of the tab when opening the can, the tab will be torn at the bent part (5). There is no such thing.

Referring to FIG. 2, a: the tab body (3) and the tab handle (6) are made separately, and b: a small protrusion provided at a predetermined position on the can lid (1). Caulking through the tab mounting holes (2), the tab body (3) is tightly attached to the can lid (1). c: One end (5) of the tab is bent into a circle, and the end (7) of the handle (6) is rotated so that the handle (6), which becomes the finger hole (4), rotates about the axis (7-8). ) And (8) are inserted in (5). d: The position of the finger hole (4) of the handle is a structure to cover the tab mounting hole (2) when the tab is folded.

In order to open the can, not only does the position of the finger hole (4) on the handle rise above the edge of the can when the end of the handle is raised, but the size of the finger hole is large enough to insert a finger. That's why it is easier to insert your finger into the finger hole compared to the conventional tabs. Then pull the tab up harder and the pull-open can lid will open as per the cut on the can lid.

Referring to FIG. 3, a: the tab body (3) and the tab handle (6) are made separately, and b: a small protrusion provided at a predetermined position on the can lid (1). Caulking through the tab mounting holes (2), the tab body (3) is tightly attached to the can lid (1). c: Both ends (7) and (8) of the handle are bent to form a straight line facing each other on the same line. d: Bend both the ears (9) and (10) on both sides of the end of the body (3) upward or downward in a U shape, and make a hole in the ears for inserting the handle (6). It is being done. e: Insert both ends (7) and (8) of the handle into the ear hole,
The handle (6) is attached to the tab (3) so that it can rotate about the axis (7-8). f: The position of the finger hole (4) of the handle is designed to cover the tab mounting hole (2) when the handle is folded.

In order to open the can, not only does the position of the finger hole (4) on the handle rise above the edge of the can when the end of the handle is raised, but the size of the finger hole is large enough to insert a finger. That's why it is easier to insert your finger into the finger hole compared to the conventional tabs. Then pull the tab up harder and the pull-open can lid will open as per the cut on the can lid.
