DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual can opener used for opening cans and the like.

[0002]

2. Description of the Related Art Conventionally, can openers of various shapes and structures, such as electric and manual types, have been developed for use in opening cans and the like. Is often used.

[0003] As a manual can opener, a notch engaging device for engaging a peripheral portion of a can, a cutting blade for cutting a lid surface of a can, and a cutting member having a size enough to allow a person to grasp with one hand. In general, a structure provided with is provided.

When a can is opened using such a can opener, a notch engaging tool is engaged with the peripheral portion of the can, and a force is applied in a direction in which the upright grip portion is inclined using this portion as a fulcrum. The cutting blade is pressed against the lid surface of the can and cuts along the periphery.

However, the conventional can opener has a problem in that the gripping portion is loose during the cutting operation, so that it is difficult to apply a force, and the notch locking device is easily detached from the peripheral portion of the can. I can't cut it without it. For this reason, the conventional can opener is a tool that is difficult to use for children, the elderly, the handicapped, or the clumsy.

Therefore, in order to solve such a problem,
A can opener having a structure in which the notch locking member is difficult to be detached from the periphery of the can has been developed, and is disclosed, for example, in Japanese Utility Model Laid-Open No. 57-95397.

[0007]

Problems to be Solved by the Invention
The can opener disclosed in Japanese Patent Application Publication No. 7-107803 is provided with a gap forming plate at a position facing the tip of the cutting blade so that the periphery of the can can be sandwiched between the cutting blade and the gap forming plate. Prevents wobbling inside.

[0008] However, in this can opener, since the distance between the cutting blade and the gap forming plate is constant, the size of the can that can be easily and securely mounted is limited. In addition, it is very difficult to attach the can opener, and conversely, the mounting state is so loose that the wobble cannot be prevented, and there is a risk of injury when the can opener comes off when force is applied. In addition, when opening cans of a size and shape where it is difficult to attach can openers, the can openers cannot be moved smoothly along the periphery of the cans. Is also large.

In addition, when a conventional can opener is used, it is attached to the periphery of the can in an upright state, and then a force is applied at a position higher than the can main body in a direction to incline the can opener. The applied force can cause the can to tilt or fall. Furthermore, since this direction is also a direction where it is difficult for a person to apply a large force, it is a difficult task for a person with a weak force.

Accordingly, an object of the present invention is to provide a can opener that can easily and safely perform a can opener operation in a stable state regardless of the size and shape of the can.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a holding member having a notch hole for locking the periphery of a can on a holding member which can be held by a human hand; In a can opener provided with a cutting blade for cutting a cover surface, a locking auxiliary member for opening and closing a notch hole is provided.

The provision of such a locking auxiliary member makes it possible to change the width of the notch, so that if the notch is widened, it is easy to engage and disengage with the peripheral portion of the can. Thereafter, if the notch hole is narrowed, the engagement can be reliably performed, and the can opener can be easily and safely performed in a stable state without wobbling or coming off during the can opener. In this case, if a temporary locking mechanism for preventing the movement of the locking auxiliary member during the can opener operation is provided, the stability is improved. In addition, if the mechanism is such that the width of the cutout hole can be changed depending on the position of the locking auxiliary member, a reliable locking state can be obtained regardless of the size or shape of the can.

Further, in the can opener of the present invention, the locking device is arranged such that the axial direction of the notch hole is substantially parallel to the axial direction of the gripping member. By adopting such a structure, when the can opener is attached to the periphery of the can, the gripping member is in a substantially horizontal state, so that if a force is applied vertically downward, the can opener can be performed, and this direction is human-friendly. Workability is improved because the direction is easy to apply force,
As compared with the conventional can opener used in the upright state, the position where the force is applied is lower, so that there is no danger of tilting or falling down the can.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view showing a can opener according to an embodiment, FIG. 2 is a perspective view showing a use state of the can opener, FIG. 3 is a sectional view taken along line AA of FIG. 2, and FIG. It is a partially notched side view shown.

As shown in FIGS. 1 to 3, a can opener 10 according to the present embodiment includes a can 1
A locking member 15 having a notch hole 14 for locking to the peripheral portion 12a of the second and a cutting blade 13 for cutting the lid surface 12b of the can 12; and a locking auxiliary member for opening and closing the notch hole 14. 16 are provided.

A total of four long holes 17 are formed on both side surfaces of the locking auxiliary member 16, and the studs 18 inserted into each of the long holes 17 are formed.
As a result, the auxiliary locking member 16 is slidable in the direction of the arrow 20.

Furthermore, since the recesses 17a are respectively formed in the two long holes 17 located at the time of use, when the locking assisting member 16 is slid downward, the studs 18 fit into the recesses 17a. In the state of being joined, the locking auxiliary member 1
6 can be temporarily locked. In this case, FIG.
As shown in FIG. 5, a mechanism is provided in which the convex portion 21 formed on the back surface of the locking auxiliary member 16 fits into the concave portion 22 formed on the locking member 15, so that the locking auxiliary member is 1
6 does not slide on its own.

As described above, it is possible to change the width of the cutout hole 14 by sliding the locking auxiliary member 16. It is easy to engage and disengage. After the notch hole 14 is locked to the peripheral portion 12a, the locking auxiliary member 1 is attached to the peripheral portion 12a.
If the notch 14 is narrowed by sliding until it comes into contact with 6, it can be reliably locked to the peripheral edge portion 12a.

Therefore, during the can opener operation, the stopper 15
Or the gripping member 11 fluctuates, or the peripheral portion 12a of the can 12
It is possible to easily and safely perform the can opener operation in a stable state without coming off. In addition, since the width of the cutout hole 14 can be easily changed by sliding the locking assisting member 16, the attachment and detachment is easy regardless of the shape and size of the can 12.

In the can opener 10 of the present embodiment, the axial direction 14a of the notch hole 14 is
The locking member 15 is arranged so as to be substantially parallel to the above. Therefore, as shown in FIG. 2, when the can opener 10 is mounted on the peripheral edge portion 12a of the can 12, the gripping member 11 is in a substantially horizontal state, so that if a force is applied vertically downward, the can opener can be performed.

This direction is also a direction in which a person can easily apply a large force, which makes it easier for a person with weak force to open the can. In addition, since the position where the force is applied is lower than in the conventional can opener, the can 12 can be tilted, There is no danger of overthrowing.

Further, in the case of the can opener 10 of the present embodiment,
With the notch hole 14 attached to the peripheral edge 12a of the can 12,
Since the cutting edge 13 is bent toward the inside of the can 12, the curved surface of the cutting edge 13 easily matches the curve of the peripheral portion 12a. The tool 15 can be moved smoothly. Therefore, relatively small cans or planar shapes are quadrilaterals,
The workability when opening a can having a curved peripheral portion with a large curvature, such as an oval or oval can, is improved.

As described above, by using the can opener 10 of the present embodiment, regardless of the size and shape of the can,
The can opener can be easily and safely performed in a stable state.
