Description

{Tool for Safe Can Opening}

The present invention relates to a new canned can opening tool in which a hand or a finger bail does not occur. More specifically, the present invention can securely fasten the canned can, and slowly open the can lid using a small force, To the opening of the housing.

Finger-cutting accidents caused by tuna can lid are a common occurrence in the home, so if you hit the keyword "tuna can finger cutting" in the Internet search word window, you can find a lot of cases in the process of picking tuna can. Usually, it may be a small scar on the fingers, but many cases can lead to a big accident with severe bleeding.

1 shows an example in which an adult holds a tuna can body 110 with a left hand 100 and a finger is inserted into a finger ring 140 connected to the can lid 130 with a right hand 120 to open the can lid 130 only by its own force . In fact, when you open a tuna can, you will experience the fact that it is not easy to open the lid even for an adult. This is because the structure of the tuna can lid requires a great deal of force in this process because it does not use the principle of leverage but simply pulls the lid with the force of the finger.

Because of the need for such a large force, adults can not easily draw cans. When the final lid is opened, the force is not controlled and there is a danger that the open lid may erroneously fly in an irregular direction in an instant or strike another hand or forearm do.

2 shows a state in which the finger ring 140 of the tuna can lid 130 is broken. The hook part of the tuna can lid breaks if you give it a wrong force once or twice. It is like a phenomenon that if you repeatedly bend a wire string repeatedly, it breaks. In this case, attempting to open the damaged lid further requires attention because it is possible that the edge of the lid may already be curled due to the edge of the lid.

Various methods have been tried to solve this problem, and a registration utility model (Registration No. 20-0317390) describes a one-touch tuna can opener. This is a can opener composed of a can opener hook, a support and a handle, and is a tool for inserting the opener hook into the finger ring of the can opener and using an opener support and a handle. A public utility model (Publication No. 20-2008-0004403) is for a can opener with a catch on the bottom of the can opener body, and a finger ring is attached to the catch, and the can opener is opened by pulling the can opener. Both of them are handled by the finger force of the human being, and the can opening process is processed by the leverage effect of the opener with the hook or the latch, which is advantageous in that the force is less when opening. However, So that it is not provided with a function of separating the hand from the sharp edge of the lid during the lid opening process, so that the danger in the opening process still exists.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and a new opening mechanism can secure the canned can and securely open the can lid by opening the can lid slowly using a small force. Canned cans are cylindrical (cylinder) shaped, similar in shape, but vary in diameter and height. The apparatus proposed in the present invention should be a mechanism capable of opening all of the canned cans having various diameters and heights at home.

In order to solve the above-described problems, the present invention provides a V-shaped structure (310) capable of pushing a lower portion of a can containing a lid of canned cans having various diameters inwardly along a groove (300); A rod 320 having one end rotatably supported on the V-shaped structure 310 and the other end passing through the can lid finger ring 140 and preventing slippage of the finger ring during the opening process, And a rotation support element 340 to which the rod is supported and rotated. The V-shaped structure 310 has a wide inlet and a narrower width as it goes inward. The material of the V-shaped structure 310 is iron or plastic. A groove, which can push the lid metal frame 430 of the can, As shown in FIG. The rotation support element 340 is composed of a rotation axis 330 to which the rod 320 is connected and a pivot structure for fixing the center of the rotation axis. The rod and the rotating shaft constitute a pivoting element, and the bearing is used when the pivoting element is connected to the V-shaped structure. The rod and the rotating shaft constitute a pivoting element, and when the pivoting element is connected to the V-shaped structure, the pivoting element is simply rotated in the slotted hole so as not to be detached from the V-shaped structure. The section of the rod can be formed in various shapes such as a circle, a triangle, and a square, and the intermediate stop of the rod can also have various shapes such as a sphere, a cylinder, and a rectangular parallelepiped.

According to the canned can opening tool of the present invention, the can can be firmly fixed to the apparatus during opening of the can, and anyone, such as a woman or a senior citizen, can slowly open the can with a small force. There is an advantage that a finger cutting accident caused by a can lid of a can such as a tuna can, which is a safety accident, can be prevented.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 4 is a diagram showing the external shape of a tuna can, which is one type of canned can. It shows that tuna cans of various heights and various diameters such as large cans 400, medium cans 410 and small cans 420 are commercially available. The portion with the metal rim 430 is the lid portion of the can, which is displayed at the lower portion of the can in the form of 440 in the shop.

5 shows the structure of the bottom of the lid of the can. The lower part of the can is composed of a can lid 130, a finger ring 140, and a metal frame 430.

Referring to FIGS. 4 and 5, it can be seen that the canned can has a different diameter and height, and the capacity varies depending on the size, the medium, and the small size. However, in the case of the same manufacturer, the shape and size of the finger ring 140 of the can is the same. In the case of a specific product, the same metal frame 430 having a width of 2 mm (500 mm) and a height of 3 mm (510) regardless of the size of the large, medium and small sizes can secure the can lid 130 to the can body 110 It can be seen that it is used for bonding and fixing.

FIG. 3 shows a V-shaped structure 310 capable of firmly fixing canned cans of various sizes. In order to have the ability to fix canned cans of different diameters, the V-shaped structure should be of a type with a reduced width from the inlet.

The dimension of the groove 300 of the inner wall of the V-shaped structure 310 is set such that the metal rim width 500 of FIG. 5 and the width of the metal rim 500 of FIG. 5 are set so that the can lid metal rim 430 can be fitted and fixed in the case of a rectangular cross- Height 510 < / RTI >

6 shows that the shape of the inner wall groove of the V-shaped structure 310 can be a semicircular groove section 610, a triangular groove section 620, etc., in which the metal rim 430 can be received in addition to the rectangular groove section 600 .

7 is a diagram illustrating a state before a tuna can is inserted into a groove 300 of a V-shaped structure and a rod is passed through a finger ring 140 and a force is applied to the rod. When the tuna can is pushed inward along the groove 300 of the V-shaped structure 310, the width becomes narrow, so that a force for tightening the can body through the metal rim 430 is applied from the V-shaped structure. In this state, the finger ring and the intermediate stopper 350 are separated by a certain distance.

FIG. 8 is a view illustrating a process of opening the tuna can by applying a force to the rod 320 with the right hand 120 in the state of FIG. When the rod is held by the left hand 100 of the can body that is sandwiched by the body of the can body and the rod passes through the finger ring 140 and is pushed up by the right end of the rod 320, The can lid 130 is opened while rotating around the center.

The force to slide the finger ring 140 on the rod surface while the rod is rotating can be reduced. The middle stopper 350 prevents such a finger ring from slipping and acts so that a sufficient force is applied to the finger ring until the lid is opened.

9 is a view for explaining the function of the rods. The longer the rod is, the more force is applied to the can of fingers and the can lid can be opened more easily.

For example, if the length of the rod is twice the distance of the can of fingers from the center of rotation (a = 2b), the force Fb (700) acting on the can finger ring is twice the force Fa (710) So that the can lid can be opened slowly with less force.

The can is pulled upward so that the can can be firmly fixed to the inside of the V-shaped structure 310 to be firmly fixed, so that the can is not released from the V-shaped structure during the opening process, and less stress is applied to the can, And the pain is reduced.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims and equivalents thereof.
