Container sealing device
First Claim
1. A container sealing device comprising:
- an inner plug having a body part disposed integrally at a mouth part of a container and a separation part joined to the body part via a score and forming an opening by being separated from the body part;
an upper lid engaged with the separation part and screwed to the container or the body part so as to cover the inner plug;
a positioning mechanism that enables assembling of the inner plug to the upper lid such that a margin allowing tightening is provided between the upper lid and the inner plug when the inner plug is assembled to the upper lid, wherein the positioning mechanism has;
a convex part formed on either one of a lower surface of the upper lid and an upper surface of the inner plug, and a concave part formed at a facing spot on the other surface, and wherein the amount of rotation torque needed to tighten the upper lid is increased by press-fitting the convex part into the concave part; and
a plug-opening mechanism part belonging to the inner plug and the upper lid, the plug-opening mechanism part having an upper-moving plug-opening mechanism that opens the inner plug by rotating the upper lid in a direction of loosening the upper lid with respect to the container to thereby separate the separation part from the body part while holding the separation part by a support part provided on an inner side of the upper lid, and a lower-moving plug-opening mechanism that opens the inner plug by rotating the upper lid in a direction of tightening the upper lid with respect to the container to thereby separate the separation part from the body part while holding the separation part by the support part.

Abstract
A container sealing device includes a plug-opening mechanism part belonging to the inner plug 10 and the upper lid 20; and the plug-opening mechanism part has an upper-moving plug-opening mechanism A that opens the plug by rotating the upper lid 20 in a direction of loosening the upper lid with respect to the container 1 to thereby separate the separation part 12 from the body part 11 while holding the separation part 12 by a support part provided on an inner side of the upper lid 20; and a lower-moving plug-opening mechanism B that opens the plug by rotating the upper lid 20 in a direction of tightening the upper lid 20 with respect to the container 1 to thereby separate the separation part 12 from the body part 11 while holding the separation part 12 by the support part.
