Abstract

PURPOSE:To enable a can to be opened in a simple, safe and easy manner even by old people and children by a method wherein a can opener body is slidably mounted on a strut. CONSTITUTION:By moving a lever end 14 upward until a lever 9 is separated from a top of a blade tool 4, the blade tool 4 is moved upward by the action of a restoring spring 5 and stopped by the contact of a stopper 6 with a can opener body 3. At this time, a gap between a jaw 7 and a blade tip 11 is maximized. In this state, a can 12 is set in position by abutting the jaw 7 against a bottom of an outer peripheral can edge 13. The lever end 14 is lowered, and a can lid 15 is cut by the blade tip 11. Succeedingly, by pressing up the lever 9, the blade tool 4 is moved upward by the action of the restoring spring 5. The can 12 is rotated to a target position of the blade tool 4 in its next downward movement, and the can lid is cut. Namely, the can be opened by rotating the can by a pitch with the vertical reciprocation of the lever 9.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a can opener that can be easily operated by old people, children and the like.

[0002]

2. Description of the Related Art The conventional can opener is (Public Utility Showa 55-3
6116) or (Public Practical Use Showa 56-24495), but all require a large fingertip force to operate. Further, (Public Utility Showa 57-95397) is also known and has been used in large numbers, but it is a can opener that requires much arm force although it does not require finger force as compared with the above two cases.

[Problems to be solved by the invention] In Japan, it is said that an aged society will come in the future. Even now, the nuclear family is advancing, and the number of elderly people living alone is increasing year by year. Preparing meals is an enormous effort for an elderly couple or an old man living alone. The conventional can opener is not easy to handle because the strength of the arm is weakened even if one wants to use a canned food that is relatively easy to prepare and hygienic. Also, in a dual-income family, even children whose parents are absent have insufficient arm strength, so it is also difficult to open a can. In such cases, it is the current situation that the mother opens the can and stores the contents in the refrigerator until the child returns. However, the storage often takes a long time, which is a sanitary problem. In view of such a current situation, the present invention is
We provide can openers that allow old people and children to open cans easily, safely and easily.

[0005]

According to the present invention, a pillar 2, which is fixed to a base 1, is connected slidably to the pillar 2 and a can opener main body 3, and the can opener main body 3 includes a cutting tool 4 and a cutting tool 4.
The return spring 5 that raises is urged. Further, the cutting tool 4 is provided with a stopper 6 for restricting the rise by the return spring 5. Further, a jaw 7 is provided on the lower portion of the can opener main body 3, and a lever 9 is attached to the connecting point 8 on the upper portion to make contact with the cutting tool 4 at the vertex 10 of the cutting tool. The outer ring 13 of the can 12 is inserted into the gap between the jaw 7 and the cutting edge 11, and the lever end 14 is pushed down to cut the can lid 15.

[0006]

In the present invention, when the lever end 14 is raised until the lever 9 moves away from the apex of the cutting tool 4, the cutting tool 4 is lifted by the action of the return spring 5, and the stopper 6 comes into contact with the can opener main body 3 and stops. The gap between the jaw 7 and the cutting edge 11 is maximized, and the opening is sufficient for the can 12 to be inserted safely. Canned 1
When the jaw 7 is applied to the bottom of the outer ring 13 of 2, and the lever end 14 is lowered to cut the can lid 15 with the cutting edge 11, the distance from the jaw 7 to the cutting edge 11 is short and the center of the can 12 is located. The can 12 is stable on the base 1 and does not need to be fixed by hand so that the can 12 does not move like the conventional can opener, and can be operated safely. Further, since the ratio of the distance from the connecting point 8 between the lever 9 and the can opener body 3 to the lever end 14 and the distance from the connecting point 8 to the apex 10 of the cutting tool is large, the force of pushing the can lid 15 at the lever end 14 is extremely high. It will be small. When the lever 9 is pushed up, the blade 4 is raised by the action of the return spring 5 biased by the blade 4, so that the can 12 can be easily rotated to the position where the blade 4 is next lowered. When the can lid 15 has been cut, the lever 9 is the top 10 of the cutting tool.
If the lever end 14 is lifted up until it is separated, the gap between the jaw 7 and the cutting edge 11 is maximized, and the can 12 can be taken out safely and easily. 12 canned tall or 12 canned short
When opening, the height can be easily adjusted by sliding the can opener body 3 along the column 2.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view of an essential part showing one embodiment of a can opener according to the present invention, and FIG. 2 is a sectional view of an essential part showing a different embodiment of the present invention. The detailed structure of the present invention is as follows. First, referring to FIG.
The supporting column 2 fixed to the and the can opener main body 3 are slidably coupled, and a blade 4 and a return spring 5 for raising the blade 4 are biased to the can opener main body 3. Further, the cutting tool 4 is provided with a stopper 6 for restricting the rise by the return spring 5. Further, a jaw 7 is provided on the lower portion of the can opener main body 3, and a lever 9 is attached to the connecting point 8 on the upper portion to make contact with the cutting tool 4 at the vertex 10 of the cutting tool. In the gap between the jaw 7 and the cutting edge 11, the outer ring 1 of the canned product 12
3 is inserted and the lever end 14 is pushed down to cut the can lid 15.

FIG. 2 is different in that the support column 2 is housed inside the can opener main body 3, and the other parts are as shown in FIG.
The structure is the same as the one shown in the figure, and the structure is simplified by configuring in this way.

[0009]

The present invention has the above-described structure. Next, the effect based on the structure of the present invention will be described with reference to FIG. 1. The distance from the connecting point 8 to the lever end 14 and the connecting point will be described. Since the ratio of the distance from 8 to the apex 10 of the cutting tool is large, the force of pushing the can lid 15 at the lever end 14 is extremely small,
Even an old man or a child can easily open the canned food 12. Also, at the beginning or the end of cutting of the can lid 15, if the lever end 14 is mentioned above until the lever 9 is separated from the apex 10 of the cutting tool, the gap between the jaw 7 and the cutting edge 11 becomes the maximum, and the can 1
2 can be inserted and removed safely and easily. or,
Since the height can be adjusted by sliding the can opener main body 3 along the support column 2, a tall canned food 12 or a short canned food 12 can be opened without being restricted in height. Further, when the can lid 15 is cut, the distance from the jaw 7 to the cutting edge 11 is short, and since it is located on the center line of the can 12, the can 12 is stable on the base 1 and can 12 as in the conventional can opener. It does not need to be fixed by hand so that it does not move, and can be operated safely.
