Raw egg cracker

Abstract

To provide a raw egg cracker capable of cracking only the outer shell of a raw egg without damaging the yolk membrane when one hand cannot be used due to an accident or illness, and having a place for placing the raw egg. [Solution] A raw egg cracking tool is attached to a board with a hole for standing a raw egg up, and a trough-shaped knife is attached with the blade facing up. When the tool is placed on a chopping board with the top convex, it has a rectangular shape when viewed from above, and when viewed from the longitudinal direction, the angle formed by two lines perpendicular to tangents drawn to two points on an arc with a large cross section is less than 90 degrees.

Description

[Technical field]

[0001] To provide a self-help device for cracking only the outer shell of a raw egg with one hand without damaging the vitelline membrane, even when one hand cannot be used due to an accident or illness. [Background technology]

[0002] Knives with a handle that can crack only the outer shell of a raw egg without injuring the user or damaging the vitelline membrane have been invented. Also, egg stands with a place to crack boiled eggs have been invented. However, there was no tool that combined a raw egg cracking knife without a handle and a place to place a raw egg.

[0003] [Patent Document 1] Mito 3243515 [Patent Document 2] Mito 3247277 Summary of the Invention [Problem to be solved by the invention]

[0004] To propose a raw egg cracker capable of cracking only the outer shell of a raw egg without damaging the vitelline membrane when one hand cannot be used due to an accident or illness, and having a place for placing the raw egg. [Means for solving the problem]

[0005] A raw egg cracking tool is a board with a hole for standing a raw egg up, and a groove-shaped knife is attached with the blade facing up.When placed on a chopping board with the top convex, it appears rectangular when viewed from above, and when viewed from the longitudinal direction, the angle formed by two lines perpendicular to tangents drawn to two points on an arc with a large cross section is less than 90 degrees. Effect of the Invention

[0006] With this invented raw egg cracker, even if you are unable to use one hand due to an accident or illness, you can crack just the shell of a raw egg taken out of the refrigerator without damaging the vitelline membrane. By using the functions of the parts of the body that you can use, it may help the user become independent, prevent a decline in physical function, and reduce the burden on care staff. [Brief description of the drawings]

[0007] [Figure 1] FIG. 1 is a perspective view of one embodiment of a raw egg cracking tool according to the present invention in a pre-assembled state. [Diagram 2] FIG. 2 is a perspective view of one embodiment of the raw egg cracking tool of the present invention after assembly. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] If the board is made of burnt cedar, it will be water resistant. If the knife part is made of bamboo, it will be easy to disassemble for cleaning and to replace parts. It will also be easy to dispose of it if it is damaged or deteriorated. The materials are not limited to burnt cedar or bamboo. EXAMPLES

[0009] A square board measuring 12.5 cm on a side was cut out from a 1.5 cm thick cedar board, a hole measuring 3.5 cm in diameter was drilled in the center of the board, and then it was charred. A bamboo knife measuring 0.9 cm thick, 5.2 cm wide, and 11 cm long was attached to the side of the board to create a raw egg cracking tool. A raw egg taken out of the refrigerator was placed in the hole in the completed raw egg cracking tool, and it was confirmed that it was possible to crack only the outer shell of the raw egg without damaging the vitelline membrane. [Industrial Applicability]

[0010] If a person cannot use one hand due to an accident or illness, the raw egg cracker of this invention can crack only the outer shell of a raw egg taken out of the refrigerator without damaging the vitelline membrane. By using the functions of the part of the body that can be used, it can help the user become independent, prevent the decline of physical function, and reduce the burden on care staff, so it is expected to be in demand at home and in elderly care facilities.

Claims

[Claim 1] This raw egg cracking tool is attached to a board having a hole for standing a raw egg, with a groove-shaped knife attached with its blade facing up, which is rectangular when viewed from above when placed on a chopping board with the top convex, and has an angle of less than 90 degrees formed by two lines perpendicular to tangents drawn to two points on a circular arc with a large cross section when viewed from the longitudinal direction.
