Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a lid whose top surface is opened by a pull tab.

[Conventional technology]

BACKGROUND ART Conventionally, lids that are opened with pull tabs have often been used for drinking water cans and the like. There were two types of these: one in which a portion of the top panel was opened, and one in which the peripheral edge of the top panel was left open.

In addition, in this type of configuration, a score line is engraved in the shape of an opening piece on the surface of the panel that makes up the lid of the can.
A pull tab to which stress is applied to break the score line was attached to the lid with rivets so that it could be pulled up. Therefore, by pulling the pull tab, stress is applied to the score line using the rivet-crimped part as a fulcrum, causing it to break and open into the shape of an opening piece.

[The problem that the idea aims to solve]

However, in this type of configuration, the shape of the opening in the lid body is determined by the way the score line is provided. Therefore, cans with small openings had no other use and had to be thrown away once the drinking water had been consumed. In addition, cans with a large opening can be used outdoors as a drinking cup even after drinking, but they tend to spill easily and are unsuitable for drinking in places with vibrations, such as in a car.

[Means to solve problems]

A finger hook 5 is provided at one end of the pull tab 7, and a pressing portion 8 is provided at the other end. A caulking hole 6 is bored between the finger hook part 5 and the pressing part 8.

In the panel 3, a pull tab 7 is rotatably crimped by a rivet 4 so that the pull tab 7 can be pulled up from the finger hook 5 side by a crimping hole 6. On the surface of this panel 3, a substantially U-shaped score line 9 that is broken by the pushing part 8 of the pulled pull tab 7 and has a small opening is engraved, and furthermore, this U-shaped score line 9 is Separately, a ring-shaped arcuate score line 15 and an annular score line 13 that reach the peripheral edge part 12 and have a large opening along the peripheral edge part 12 are carved.

The present invention is a lid body comprising the pull tab 7 and panel 3 described above, and allows the size of the opening of the panel 3 to be arbitrarily selected depending on the direction of the pressing portion 8 of the pull tab 7.

[Effect]

Rotate the pull tab 7 and press the rivet 4 with the pressing part 8 at the tip facing the U-shaped score line 9.
When the finger hook part 5 of the pull tab 7 is raised using the finger holding part 5 as a fulcrum, the substantially U-shaped score line 9 is broken by the pressing part 8, and a small opening is opened in the upper surface of the panel 3.

Also, rotate the pull tab 7 and press the pressing part 8 at the tip.
If the finger hook part 5 of the pull tab 7 is pulled up using the rivet 4 as a fulcrum while pointing in the direction of the arcuate score line 15 reaching the peripheral edge 12, the arcuate score line 15 and the annular score line 13 will break. The panel 3 can then fall off, leaving the panel 3 wide open.

〔Example〕

The lid body 2 of the present invention is fixed to the upper surface of the vessel body 1. The pull tab 7 has a finger hook 5 and a caulking hole 6.
is drilled, and a pressing part 8 is provided at the tip of the caulking hole 6.
is provided. This pull tab 7 has a caulking hole 6 which is caulked to the panel 3 of the lid body 2 by a rivet 4 so that it cannot fall off but is rotatable about the rivet 4. The pull tab 7 is configured to be pulled up from the finger rest 5.

This panel 3 is engraved with a U-shaped score line 9, an arcuate score line 15, and a circular score line 13. The U-shaped score line 9 is carved in a substantially U-shape that starts near the rivet 4 and returns to the vicinity of the rivet 4, and forms a small opening piece 10 on the inside. This small opening piece 10 is the pressing part 8 of the pull tab 7.
When the finger rest part 5 is raised with the finger facing in the direction of the U-shaped score line 9, it is pressed down by the pressing part 8 at the tip, and is configured to break and open from the U-shaped score line 9.

Further, on the opposite side of this U-shaped score line 9, there is an arcuate score line 1 whose both ends reach the peripheral edge 12 of the lid body 2.
5 is engraved, and a large opening piece 16 is formed on the inside. Furthermore, continuous to this arc score line 15,
An annular score line 13 connecting both ends of the arcuate score line 15 is carved in an annular shape along the peripheral edge 12 of the lid body 2. This arcuate score line 15 indicates that when the pull tab 7 of the lid body 2 is rotated 180 degrees around the rivet 4 and the pressing part 8 is directed in the direction of the arcuate score line 15, the finger hook part 5 of the pull tab 7 is raised. When pressed by the pressing part 8 at the tip,
It is configured to break and open at the arcuate score line 15.

Since the embodiment of the present invention has the above-mentioned configuration, if the finger hook part 5 is pulled up by pointing the pressing part 8 of the pull tab 7 in the direction of the U-shaped score line 9, the U-shaped score line 9 will break and a small hole will be formed in the panel 3. . Also, pull tab 7
When the finger hook part 5 is pulled up by pointing the pressing part 8 in the direction of the circular score line 15, the circular score line 15 is first broken, and then the circular score line 1 is broken.
3 breaks, most of the panel 3 falls off together with the pull tab 7, and the upper part of the container body 1 opens wide.

In addition, it is preferable that reinforcing ribs 14 are provided on the small opening piece 10, the pressing part 8, etc. so that the score lines 9, 13, and 15 can be broken effectively. Further, if the U-shaped score line 9, arcuate score line 15, and annular score line 13 are configured to be continuous with smooth curves, it is safe to avoid hurting hands or mouth with sharp parts.

Furthermore, the present invention does not require the rivet 4 to be provided in the center. This configuration is shown in FIG.

[Effect of idea]

As described above, in the lid body 2 of the present invention, by changing the direction of the pressing part 8 of the pull tab 7, it is possible to arbitrarily select whether the upper surface of the vessel body 1 is opened small or wide. It's summery. Therefore, if the opening is made small, it can be drunk in the same way as a conventional drinking water can, and it is difficult to spill even in a car. Furthermore, if the drinking water is not cold, you can open it wide and add ice. What's more, if you open it wide after you've finished drinking, it will form a pot and can be reused for various purposes.

It can also be used in applications where the contents are a mixture of liquid and solid, a small opening is made to first drain the liquid, and then a large opening is made to take out the solid.

As mentioned above, the present invention is designed to prevent
Not only can the consumer choose whether to open the bottle small or large depending on their preference, but after drinking, the bottle can be opened wide and shaped into a pot, allowing it to be reused for other purposes. The lid body 2 is also effective from the viewpoint of resource reuse.
