Title:
LIQUID SUBSTANCE ADVANCING CONTAINER
Document Type and Number:
WIPO Patent Application WO/2014/129645
Kind Code:
A1
Abstract:
Provided is a liquid substance advancing container which is configured so that a piston (18) is capable of being advanced without problem, the liquid containing capacity of a shaft cylinder is capable of being increased, the liquid substance advancing container uses a reduced number of parts, a die is capable of being worked easily, and the liquid substance advancing container is capable of being configured at low cost.
The liquid substance advancing container is configured such that: the piston (18) has a seal section (32) disposed at the front part of the piston (18), the seal section (32) being in sliding contact with the inner wall of the receiving section of a shaft body, the piston (18) also having a bar member (34) disposed at the rear part of the piston (18), the bar member (34) having a thread section formed on the inner periphery or the outer periphery of the bar member (34), the bar member (34) being disposed so that the bar member (34) is capable of moving in the axial direction and is prevented from moving in the rotational direction; a thread section is formed on a front bar-like section (36) which extends forward from an operating section, the thread section directly or indirectly engaging with the thread section of the bar member (34) disposed at the rear part of the piston; and the liquid substance advancing container is configured such that rotating the operating section relative to the shaft body (10) advances the piston (18) and such that, after the piston (18) is advanced, the front bar-like section (36) is capable of being extended and retracted in multiple stages.
