Abstract

(57) [Summary] [Objective] To provide a square can opener capable of cutting the corner portion of the top plate portion of the square can in a curved shape. [Structure] Bent portions 5 and 5 are formed at both end portions of a pentagonal flat plate 4 having a grip portion 3 on an upper portion thereof, and the entire lengths of both inclined side portions of the pentagonal flat plate 4 are made into sharp cutting edges 6 and 6. When cutting the top plate along a straight edge, both side corners can be cut in a curved shape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a square can opener for easily opening the top plate part of a square can such as a metal one-toe can.

[0002]

[Prior art]

 When a highly viscous liquid such as starch syrup is contained in a metal canister or the like, it takes a lot of time to take out the contents from the round small diameter opening, which is quite troublesome. .

For this reason, it is necessary to cut open the top plate of the one-pot can or cut it out before taking out the contents.

Conventionally, some blades have been used as a means for cutting the top plate portion of an Ito can, as exemplified below. (B) Use a knife like a knife and hit the knife with a hammer to cut the top plate. (B) Cut the top plate with a can opener for round cans. (C) Using a flat-plate can opener with a V-shaped blade edge, press the top plate off.

[0005]

[Problems to be solved by the device]

 By the way, the means (a) is not preferable because there is a possibility that the hand may be struck by a hammer at the time of cutting work, or a flame of a dangerous substance may be caused by a spark generated at the time of hitting.

Further, the means using a can opener for a round can, like the means (b), has a problem that it is difficult to cut because a sufficient force cannot be applied at the time of cutting.

Further, as in the case of (C), the flat-plate one-tower can opener is easy to cut a straight line portion, but the arc-shaped corner portion of the one-tower can is difficult to cut. Moreover, the angle of the cut top plate becomes a right angle, and there is a problem that it is easy to cut the hand at this part.

Therefore, the present invention was obtained as a result of an original study to improve the one-tower can opener shown in the above-mentioned conventional (C) means, and is obtained from a straight part of a square can to an arc-shaped corner part. It is an object of the present invention to provide a square can opener that can be easily cut, and that the cut top plate and the corners of the can are curved so that the hands are not injured.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a grip portion on the upper portion of a pentagonal flat plate whose lower end is sharpened by the inclined side portions on both sides, and places both end portions of this pentagonal flat plate on the same plane side. The pentagonal flat plate is formed in a bent portion that is bent into an arc shape, and the entire length of both inclined side portions of the pentagonal plate is a sharp cutting edge.

[0010]

[Action]

 To cut off the top plate of a square can, hold the grip with your hand and push down the tip of the blade to the center of the straight edge on the top of the square can. The bent parts on both ends can cut the arc-shaped corners of the square can in an arc shape.In this way, the top plate can be cut off by cutting the four edges of the top plate. The corners of the top plate and the square can are curved and the hands are less likely to be injured.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a square can opener 1 is formed of a blade portion 2 and a grip portion 3 provided on the upper portion of the blade portion 2, and the blade portion 2 has a sharpened lower end with inclined side portions on both sides. A pentagonal flat plate 4 is used, and both end portions of the pentagonal flat plate 4 are bent into the same plane to form bent portions 5 and 5, and the entire length of the inclined side portions on both sides has a sharp cutting edge 6 and 6. ing.

The upper blade portion 2 is not limited in material as long as it is suitable as a blade such as steel, and the width W and height H of the pentagonal flat plate 4 match the size of the square can to be cut. The bending portions 5 and 5 at both end portions are bent in a circular arc shape within a range of 90 ° in a plan view.

In the illustrated case, the grip portion 3 has a mounting portion 7 that is fixed to the upper portion of the pentagonal flat plate 4, and circular shaft-shaped grips 8 and 8 that project from both sides of the mounting portion 7 to form a square can. When cutting, the square can opener 1 is held by both hands so that force can be applied to the blade part 2.

The grip portion 3 and the pentagonal flat plate 4 may be fixed to each other by an appropriate means such as bolts, and the grip portion 3 is made of wood, plastic, metal, or the like that has no problem when used. Should be adopted.

The square can opener of the present invention has the above-described structure. As shown in FIG. 2, in order to cut the top plate portion B of the square can A, the grips 8 of the grip portion 3 are grasped with both hands, and the cutlery is cut. When the tip of the portion 2 is brought into contact with the central portion of the straight edge of the top plate portion B of the square can A and a force is applied from above, the blade portion 2 penetrates while cutting the top plate portion B by the cutting edges 6 and 6 on both sides. Subsequently, the bent portions 5 and 5 at both end portions cut the corner portion of the square can A in an arc shape.

By performing such a work a total of four times along each straight edge of the square can A, the four sides of the top plate B are cut, and the square can A can be completely opened. The corners of the plate portion B and the square can A have a curved shape and no corners are formed, so that hand injury is reduced.

[0018]

[Effect of device]

 As described above, according to the present invention, the top plate can be cut by pushing it down from the top of the square can, and since there is no work to hit the blade with a hammer, the flame of combustible material caused by sparks You can safely and easily cut the top plate of the square can without risk of causing it.

Further, since the bent portions are formed at both end portions of the pentagonal flat plate, the corner portion of the square can can be cut in an arc shape, and the cut top plate portion and the corner portion of the square can are cleanly curved. It is safe without fear of being cut or injured.
