Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lid for a can whose opening area can be arbitrarily changed by changing the acting direction of the pull ring.

Traditionally, this type of lid allows the can to be opened without the use of a can opener, making it convenient to carry.
Although it is widely used in cans for foods such as beverages, in one lid, only one size of opening can be formed by pre-provided score lines. Therefore, the consumer cannot decide the size of the opening, and the size of the opening is left to the discretion of the producer. In other words, a lid that can form a small opening for drinking spout is used for liquids such as drinks so that they can be drunk directly from the can, while a lid that can form a small opening for drinking spout is used for storing solid items such as glue or candy. A lid was used that could form a large opening so that the contents could be removed by inserting one's hand into the can. However, in such can containers, the opening is small and inconvenient for consuming a large amount of drinks, etc. at once, and conversely, the opening is too large and inconvenient for dispensing candy, etc. one by one. It had the disadvantage of being.

The present invention is intended to solve such drawbacks of the conventional technology, and its purpose is to prevent the consumption of contents by providing a plurality of scheduled openings (score lines) of different sizes on the lid body in advance. To provide a lid for a can that can be adapted to various ways of consumption by allowing a consumer to arbitrarily change the opening area according to the quantity.

In order to achieve the above object, in the present invention, an arbitrary number of score lines for opening are provided on the mirror plate so that the opening starting ends of the respective openings intersect, and the opening starting ends of each of the intersecting score lines It is characterized in that a pull ring is rotatably attached to the enclosed area via a rivet, and the opening area can be arbitrarily changed by changing the direction of action of the pull ring.

The present invention having the above object will be explained based on illustrated embodiments. In FIGS. 1 and 2,
1 is a lid of a can body container according to the present invention;
It is composed of an end plate 2 and a pull ring 4 rotatably attached to the end plate 2 via a rivet 3. More specifically, the mirror plate 2 has a full-opening score line 21a with a V-shaped cross section and a partial opening score line 21b with a V-shaped cross section on its upper surface, and the opening directions of both are at an angle of 180 degrees with respect to each other. It is arranged so that it has. This score line 21a for full opening is continuous with a V-shaped part A extending radially from the center of the mirror plate 2 at a predetermined angle, and a straight part _A1 on the left side of the V-shaped part, making one circuit clockwise around the periphery of the mirror plate 2. A curved line having a curvature smaller than that of the circumferential portion B ₁ , which is continuous with the right straight portion A ₂ of _the V-shaped portion and extends 1/1/2 inward of the circumferential portion B ₁ clockwise. 3
It is composed of a circumferential curved part _B2 . Then, the score line 21a for the entire opening breaks the head plate 2 in a substantially triangular shape from the bent part of the V-shaped part A toward the outside in the radial direction, and then extends along the circumferential part _B1 and the curved part _B2 to the periphery of the head plate 2. Cut into strips and then cut around the circumference.
By guiding the break line along _B1 , a circular opening 22a is formed in the vicinity of the periphery of the end plate 2. On the other hand, the partial opening score line 21b has a V-shaped portion A' extending from the center of the mirror plate 2 in a diametrically opposite direction to the V-shaped portion A of the full-surface opening score line 21a, and a V-shaped portion near the periphery of the mirror plate 2. A curved part B' connects both ends of the V-shaped part A', and the partial opening score line 21b is formed by cutting the mirror plate 2 from the bent part of the V-shaped part A' in the direction of the curved part B'. small shaped opening 22
b.

The pull ring 4 consists of an annular lifting part 41 for lifting by inserting a finger, and a substantially rectangular mounting part 42 following the lifting part 41, and the mounting part 42 engages the rivet 3 in the center. It is provided with an engagement hole 43 that allows the holder to move, and a pair of action parts 44 are provided by cutting out the left and right corners of the outer tip into a rectangular shape. As shown in FIG. 3, the rivet 3 is a protruding and deformed part of the mirror plate 2, and as shown in FIG.
1a and the opening starting end of the score line 21b. The pull ring 4 having such a structure is rotatably attached to the intersecting position of the starting ends of the score lines 21a and 21b on the mirror plate 2 by engaging the rivet 3 and the engagement hole 43. Rotate the pull ring 4 and select the score line 2 that you want to cut.
Pull the action part 4 of the ring towards the opening direction of 1a or 21b.
4 can be placed. Further, to explain in detail the action portions 44 of the pull ring, the action portions 44 are located outside the opening start end of the score line 21a or 21b, and when the lifting portion 41 is pulled up, the pair of action portions 44 open. Press the end plate 2 outside the score line 21a or 21b. Further, by pulling up the lifting part 41, the attachment part 42 is pulled upward together with the end plate 2 by a lever action using the action part 44 as a fulcrum, and the end plate 2 is broken at the opening start end of the score line 21a or 21b, and the opening is opened. Part 22a or 22b
A forming cut is formed.

In addition, when pulling up the pull ring 4 and breaking the end plate 2 along one score line, the direction in which the pull ring 4 is pulled up does not match the shearing direction on the other score line, so the other score There will be no breaks in the wire, and the rivet 3 and pull ring 4 will not fall off.

When consuming a small amount of contents in a can using the lid of the present invention having the above configuration,
As shown in FIG. 1A, the action part 44 is moved in the opening direction (inward of the V-shaped part A') of the partial opening score line 21b for forming the small opening 22b by rotating the pull ring 4. Leave it in place. Next, when the lifting part 41 located outside the score line 21b is pulled upward, a lever action using the action part 44 as a fulcrum causes
Score line 2 located closer to the lifting part 41 than the action part 44
Only the opening starting end of 1b is pulled upward and broken. When the lifting part 41 is further pulled toward the opening, an opening 22b having a small area is formed.

In addition, when consuming a large amount of contents at once, as shown in FIG. It is positioned in the opening direction of the score line 21a (inside the V-shaped part A). Thereafter, by performing the same operation as above, the entire surface can be opened, and an opening 22a having a large area is formed.

FIG. 5 shows another embodiment of the present invention, and the same components as in the first embodiment will be described with the same reference numerals. , the end plate 2 has a cross section V
A character-shaped partial opening score line 21c is provided, and the opening starting end of this score line 21c intersects the opening starting ends of the score lines 21a and 21b at an angle of 90 degrees. The score line 21c is a V extending radially outward from the center of the mirror plate 2.
It consists of a shaped portion A'' and a curved portion B'' that connects both ends of the V-shaped portion A'' near the periphery of the mirror plate 2.
The angle of the V-shaped part A'' of this partial opening score line is the V-shaped part of the other partial opening score line.
larger than the angle of A', openings 22a and 22
This is for forming a fan-shaped opening 22c having an area intermediate between the area b and the opening area 22c, which has the advantage that the opening area can be changed steplessly compared to the first embodiment. The other configurations are the same as those in the first embodiment, and will therefore be omitted.

The present invention has the above-mentioned structure and function, and since a plurality of planned opening areas (score lines) of different sizes are provided in advance on the lid, consumers can freely set the opening area according to the consumption amount of the contents. This has the effect of being able to adapt to a wide variety of ways of consumption.
