Abstract

PURPOSE: To obtain a drink can that can easily open a mouth by holding the can by one hand and pushing a soft part for the convenience of use and has a small number of component parts for the ease of production by a method wherein a mechanism serving as a trigger by moving a trigger fitting for opening a mouth is provided in the can. CONSTITUTION: By holding a can by one hand and pushing a soft part 2 by a thumb, the soft part 2 is depressed. The soft part 2 is so shaped as to have a spherically projected part in the center part thereof, thereby being easily depressed even in the presence of an internal pressure of the can. A mechanism 4 moving a trigger fitting 3 proximate to the soft part 2 for opening a mouth is actuated by depressing the soft part 2. In this manner, the mouth 6 can be opened. The mechanism 4 for opening a mouth is a mechanism for opening a mouth by moving the trigger fitting 3 by a manual operation from outside the can. Alternatively, the mouth 6 can be opened by an action of a mechanism for opening the mouth by a work conserved in a spring, high-pressure gas, or vacuum existing in the can.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drink can that can be opened with one hand when drinking beer, oolong tea, carbonated drinks and the like.

[0002]

2. Description of the Related Art In a conventional drink can, when opening a drinking mouth, for example, the can is held in the left hand and the knob metal fitting in the lid is held in the right hand and pulled up. Therefore, it was necessary to use both hands. Also, the grips may hurt your nails, making them difficult to handle.

[0003]

SUMMARY OF THE INVENTION In order to eliminate the drawbacks, the present invention has an object to open a drink can with one hand and with one touch.

[0004]

[Means for Solving the Problems] A sectional view of a drink can and an operation diagram of FIG. 1 will be described. Outer cylinder of drink can 1
First, the soft portion 2 is formed, and the central portion of the soft portion 2 has a spherical convex portion 2C so that it can be pressed by the pressure of the finger 7. Inside the can, it is installed so that the soft part 2 and a part of the metal fitting 3 are close to each other. When the soft portion 2 is pushed into the can, the pulling metal 3 comes into contact with the soft portion 2 and is pushed and moved. By moving the pulling metal fitting 3, the mechanism 4 that can open the drinking mouth that operates is based on this.
Is connected and fixed to the drinking spout 6 on the lid 5. The soft portion 2 is molded inside the can a little as compared with the surface of the outer cylinder 1 so as not to receive an impact during carrying.

[0005]

The present invention has the above-described structure. For example, when the can is held with the right hand and the soft portion 2 is pushed with the thumb, the soft portion 2 is dented. The soft part 2 is
The central portion has the shape of a spherical convex portion 2C, so that it is easily dented even if there is pressure inside the can. By denting, the pulling metal fittings 3 which are close to each other are moved, and the mechanism 4 capable of opening the drinking mouth is operated. Thereby, the drinking spout 6 can be opened. The mechanism 4 that can open the drinking mouth is a mechanism that can be opened from the outside of the can, for example, by hand work by the movement of the pulling metal fitting 3, or
It is a mechanism that can be opened by work stored in a can, such as a spring, high-pressure gas, or vacuum, and the mouth 6 is opened by the action of these mechanisms.

[0006]

EXAMPLE An example of a mechanism 4 capable of opening a drinking mouth by hand work from the outside of a can will be described with reference to FIG. This figure illustrates that the drinking mouth opens in the order of (a) (b) (c). Make soft parts 2A and 2B on the outer cylinder 1 of the drink can. When the soft portions 2A and 2B are pushed by the fingers 7A and 7B, the soft portions 2A and 2B are dented, and the adjacent pulling metal fittings 3A and 3B are pushed inside to move.
The pull metal fittings 3A, 3B are molded and fixed to the lid 5 by rivet-shaped preliminary small hole projections 8A, 8B. Also,
Rivet-shaped main protrusions 9A, 9B on the mouths 6A, 6B
There are holes in the pulling metal fittings 3A and 3B, and the holes and clearances 10A and 10B and the rivet head clearances 11A and 11B are molded and assembled. When the pulling metal fittings 3A, 3B are moved slightly inward, the main protrusions 9A, 9B move to the hole clearance portions 10A,
10B and the rivet head clearances 11A and 11B are free, so the force acts only on the preliminary eyelet projections 8A and 8B.
Then, the small holes 12A are broken and opened, and air enters from the outside of the can. Therefore, the pressure inside the can is eliminated, and the outer cylinder 1 made of aluminum or the like can be easily crushed by the finger 7A. Then, the pulling metal fittings 3A and 3B are moved more and more, and the rivet head clearance portions 11A and 11B are moved.
And the main protrusions 9A and 9B will be pulled,
The drinking spouts 6A and 6B can be pulled inside, and the drinking spouts 6A and 6B are opened. Next, a first embodiment of the mechanism 4 capable of opening a drinking mouth, which is opened by the work of a spring in a can, will be described with reference to FIG. This figure illustrates that the drinking mouth opens in the order of (a) and (b). Soft part 2
When pushed by the finger 7, the pulling metal fitting 3 is pushed, and by the lever principle, the claw portion 14 is disengaged and the spring 15 is released. The spring 15 is connected by the rivet-shaped connecting convex portion 16 of the drinking spout 6. Further, the spring 15 has a non-slip portion 17 and is in contact with the convex portion 18 of the lid 5 of the can. When the spring 15 is released, the convex portion 18 serves as a fulcrum, and the joint protrusion 1 of the drinking spout 6 is formed.
6 is pulled, the drinking spout 6 is lowered, and the drinking spout 6 is opened. A second embodiment, which opens by the work of the spring in the can, is illustrated in FIG. This figure illustrates that the drinking mouth opens in the order of (a) and (b). When the soft portion 2 is pushed by the finger 7, the pulling metal fitting 3'is pushed, and the nail portion 1 is operated by the lever principle.
4'is released and the spring 15 'is released. Then pin 1
At 9, the pull metal fitting 3 ′ is pulled, and the drinking spout 6 ′, which is connected to the pull metal fitting with the rivet 20, is broken. This is due to the lever force of the raising portion 21.
After that, the spout 6'can be further opened by the force of the spring. The above two examples utilize the work of the spring, but a high-pressure small cylinder or a vacuum cylinder is put inside the can, and a needle is installed on the pulling metal fitting 3, and a hole is made in the cylinder by the needle. It is also a good method to open the mouth, open the gas pressure or vacuum, move the piston, etc., and open the drinking mouth 6 by this work.

[0007]

As described above, the present invention is convenient because it is possible to easily open the drinking mouth by holding the can with one hand and pushing the soft portion. Further, the increase in manufacturing cost is a problem, but in the embodiment, the number of parts is small, the manufacturing is easy, and the maximum cost reduction can be expected.
