Description

[Detailed Description of the Invention] The present invention relates to a lid for a can that can be easily opened by hand, and in particular, the lid can be opened entirely.

Conventionally, this kind of lid body has been constructed as shown in FIG. This is because a main score line 2 is circularly engraved on the entire circumference of the lid body 1, and an auxiliary score line 3 is formed along the main score line 2 on the inside of the main score line 2. It is engraved in the form of letters. In addition, the lid body 1 has an inverted U-shaped score line 5 for opening the lid, which defines the tongue piece 4 for opening the lid, and is engraved outward in the radial direction from the center of the lid body 1. A lid opening fitting 7 made of a pull ring 6 is fixed to the inner end of the tongue piece 4 for opening the lid with a rivet 8. Further, one end of the score line 5 for starting lid opening is connected to one end of the auxiliary score line 3 via a first curved portion 9, and the other end of the score line 5 for starting lid opening is connected to the first end of the score line 5 for starting lid opening.
It is connected to the main score line 2 via a second curved section 10 that is curved in the same direction as the curved section 9 .

To open the lid 1, raise the pull ring 6 and immediately pull it radially outward to break the lid 1 along the opening start score line 5. Cut off the tongue piece 4 for starting to open the lid. Then, by pulling the pull ring 6 clockwise along the outer periphery of the lid 1, it is connected to the score line 5 for opening the lid via the first and second curved portions 9 and 10. By cutting out the strip A between the main score line 2 and the auxiliary score line 3 along the outer periphery of the lid 1, and finally removing the entire opening surrounded by the main score line 2, The lid body 1 is designed to open completely in a circular manner.

In such a conventional example, when opening the lid, first the tongue piece 4 for starting lid opening is cut off along the score lines 5, 5, and then the strip part A is cut off along the main score line 2. Therefore, the opening distance becomes longer due to the necessity of cutting off the tongue piece 4 for starting the opening of the lid, which has the disadvantage that opening the lid is troublesome. Another drawback is that the long band-like portion A formed when the lid is opened can easily injure hands and fingers.

The present invention solves the drawbacks of the prior art by omitting the opening operation in the radial direction and allowing the lid to be opened immediately along the main score line. There is no need for extra steps such as having to cut off the starting tongue, making it extremely easy to open the lid. The purpose is to provide a lid for a can that can be opened safely without risk of injury to hands or fingers.

In the present invention having the above-mentioned object, the mirror plate is provided with a full-face opening surrounded by the main score line extending all the way around the mirror plate, and the full-face opening extends along the diameter direction of the mirror plate, and one end thereof is connected to the main score line. connected to the line, and the same full-surface opening is divided into a first opening and a second opening with a remainder remaining, and the other end is bent toward the second opening along the main score line. A score line for starting lid opening was provided, and a lid opening metal fitting was fixed to the first opening via a rivet so that its working part was located near the score line for starting lid opening.

According to the present invention, when the finger hook part of the pull ring is first pulled up with a finger, the lever action using the rivet as a fulcrum pushes down the middle part in the longitudinal direction of the score line for opening the lid, and the end plate is pushed down. is suddenly broken over almost the entire length, leaving a curved part. Next, when the pull ring is pulled up, the end plate along the score line is broken, so that the first opening can be cut out from the lid.
Then, when the pull ring is further pulled up, the second opening is similarly cut out along the main score line, so that the entire opening surrounded by the main score line is finally removed and the lid is completely opened. In this way, the opening start score line that reaches the main score line can be broken at any time by only the initial operation of raising the lid opening metal fitting, so opening the lid can be performed extremely easily.

The present invention having the above object will be explained based on the illustrated embodiments. In FIGS. 2 and 3,
11 is a mirror plate constituting the lid 1 of the can body;
A main score line 12 having a circular planar shape is engraved on the mirror plate 11 over its entire circumference, and a full-surface opening 13 is formed by a portion surrounded by the main score line 12.

A substantially arc-shaped score line 14 for opening the lid, which extends along the diameter direction of the mirror plate 11 and connects one end to the main score line 12, is engraved in this entire opening 13. 13 is divided into a large-area first opening 16 and a small-area second opening 17 by the lid-opening start score line 14, leaving a remainder 15. Further, the tip of the score line 14 for starting lid opening is connected to the second line through the bent part 14a.
A curved portion 14b is curved along the main score line 12 toward the opening 17 side.

Furthermore, a lid opening fitting 19 made of a pull ring 18 is fixed to the first opening 16 via a rivet 20. This pull ring 18 consists of a finger hook part 18a and a fixed part 18b, and a substantially chevron-shaped acting part 18' formed at the tip of the fixed part 18b corresponds to the longitudinal middle part of the lid opening start score line 14. Located nearby. The same pull ring metal 18 is closed when the lid is opened.
When the finger hook part 18a is raised, the lever action using the rivet 20 as a fulcrum causes the action part 18' to push down the middle part in the longitudinal direction of the score line 14 for opening the lid. In addition, a vent score line 21 is carved in the first opening 16 on the outer periphery of the rivet 20 and on the side opposite to the action part 18' of the pull ring 18, and this vent score line 21 is used for pulling as described above. When the finger hook part 18a of the ring ring 18 is raised, it is broken to facilitate the breaking of the score line 14 for starting lid opening by the action part 18', and also to release the gas accumulated in the upper part of the can body. It has also come to play the role of gas venting.

Next, we will explain the case of opening the lid of the can with the above structure.
When you pull up the finger hook part 18a with your finger, the same pull ring 18
The end plate along the vent score line 21 is broken due to the tensile action of the rivet 20 which is a fulcrum, and the longitudinal middle part of the score line 14 for opening the lid is broken by the action of the pull ring 18 due to the lever action using the rivet 20 as a fulcrum. The mirror plate along the score line 14 for starting lid opening is pushed down by the curved part 14'.
It is suddenly broken over almost the entire length, leaving part b. Next, when the pull ring 18 is pulled up by hooking the finger on the finger hook 18a, the main score line 1 is drawn counterclockwise from the connection point with the score line 14 for opening the lid.
Since the end plate along 2 is broken, the first opening 16 can be cut out from the lid 11. When the pull ring 18 is further pulled up, the second opening 17 is similarly cut out along the main score line 12, so that the entire opening 13 surrounded by the main score line 12 is finally removed, and the lid 11 is removed. is fully opened.

The present invention has the above-mentioned structure and operation, and the score line for starting the lid opening that reaches the main score line can be broken at any time by only the initial operation of raising the lid opening metal fitting, so it is possible to break the lid opening start score line that reaches the main score line at any time. There is no need for an extra step such as having to cut off the opening tongue when opening the lid, and the lid can be opened extremely easily. Further, unlike the conventional case, a belt-shaped broken part is not formed when opening the lid, so there is no risk of injury to hands or fingers when opening the lid, and the lid can be opened safely.
