JPH0649351U - Wedge type screw-using container and lid - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] The principle of wedges was applied to the relationship between the lid and the container to enable the lid to be tightened with less rotation. [Structure] Utilizing the wedge principle in the relation between the lid 4 and the container 3, the lid 4 is provided with a v-shaped convex triangle 2 and the container 3 is covered with the lid 4
Attach the inverted C-shaped concave 1 that receives the v-shaped convex of No. 1 and tighten the joint. In addition, to reduce the rotation of the lid 4 (pair of unevenness)
It becomes possible by increasing.

Description

[Detailed description of the device] [Industrial applications]

 This wedge-shaped container and lid device has made it possible to fix the container and the lid tightly with less rotation.

[Prior art]

 Due to the relationship between the container and the lid, it took a lot of work because it had to be rotated and tightened to be fixed.

[Problems to be solved by the device]

 Due to the relationship between the container and the lid, the nut had to be turned many times to tighten and fix it, which was troublesome.

[Means for Solving the Problem] The present invention is intended to eliminate the drawbacks of the related art. Referring to the drawings, a v-shaped triangular shape is formed inside the lid in FIG. Make a wedge and make a concave V-shape on the container to receive the v-shaped wedge. Also, when reducing the number of rotations of the lid, the solution will be to increase the number of pairs of irregularities of the same shape.

Claims (2)

[Scope of utility model registration request] 1. A v-shaped inner surface of a lid utilizing the wedge principle.
By providing a wedge-shaped triangular protrusion and a reverse c-shaped recess that receives the v-shaped wedge on the container, it is possible to firmly tighten and fix within 360 ° (1 rotation) of turning the lid. did. 2. The nut can be tightened with a small rotation angle by increasing the unevenness of the pair of the container and the lid.
