JP2005280836A - Double structural plastic screw and stopper with mechanism for preventing excessive or insufficient fastening - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To prevent volatilization, leakage accidents or the like of content by fastening a screw or a stopper plug with proper torque. <P>SOLUTION: In the stopper plug, adjustment of fastening torque is carried out in reference to a bore and diameter of cam mechanism, the number of cams or the like. When stronger fastening torque is needed or a container is broken, an outer edge of an inner cap is exposed at a lower edge of a cap, so that direct fastening is carried out without the need of the cam mechanism. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention was invented to prevent overtightening of screws and stoppers.

The present invention was invented in order to confirm overtightening of screws and plugs with sound.

The present invention was invented to prevent damage to containers and parts due to overtightening of screws and stoppers.

The present invention was invented in order to prevent volatilization of contents and leakage accidents by tightening screws and stoppers with appropriate torque.

Patent No., Patent 3472201

There are various screw tightening sensations for each individual, over tightening is insufficient, and it is difficult to make the sensation constant. Accidents such as damage to containers, damage to related parts, leakage of contents, volatilization of liquid, etc. occur due to insufficient tightening. Industrial tools often use torque measuring tools, but cannot be used in daily life. The present invention contributes to prevention of accidents due to excessive or insufficient tightening.

Double structure plastic screw, stopper, cam mechanism with overtightening prevention mechanism

In general, screws and stoppers that function by tightening depend on an individual sense of tightening. Machine tools have measuring devices with tightness to prevent accidents, but if a mechanism for preventing excessive or insufficient tightening is incorporated in the screws and plugs of daily life products, damage, leakage and accidents can be prevented, making it safer You can live a more reliable daily life.

The tightening torque is adjusted based on the cam mechanism high diameter, diameter, number of cams, and the like. When a stronger tightening torque is required or when it is broken, the outer edge of the inner crown is exposed to the lower edge of the cap and can be directly tightened without using a cam mechanism.

A damp-proof, non-volatile, carbonated beverage container stopper. Stop cock.
