Connector Structure

Abstract

A connector structure that can minimize the amount of liquid remaining in a container is provided. In a connector structure that is attached to an opening 2 of a container 1 and including a siphon tube 11 for extracting a liquid inside the container 1 with pressure of gas introduced into the container 1 , a gas channel 12 for introducing the gas and a liquid channel 13 for extracting the liquid are formed by joining together a plug 40 and a socket 20 , and an axis Cs of the siphon tube 11 and an axis Cv of the container 1 have a predetermined inclination angle θ therebetween.

1 . A connector structure attached to an opening of a container comprising a siphon tube for extracting a liquid inside the container with pressure of gas introduced into the container,
 wherein a channel for introducing the gas and a channel for extracting the liquid are formed by joining together a plug and a socket, and wherein an axis of the siphon tube and an axis of the container have a predetermined inclination angle therebetween.   
   
   
       2 . The connector structure according to  claim 1 , wherein the inclination angle is an angle between the axis of the siphon tube set vertically and the axis of the container that is set in an inclined position such that a lower end of the siphon tube is located near a lowest position on a bottom surface of the container. 
   
   
       3 . The connector structure according to  claim 1 , wherein height-adjustment means is provided which adjusts a secured position of the siphon tube in a vertical direction. 
   
   
       4 . The connector structure according to  claim 1 , wherein the socket is secured to the opening of the container while an upward-opening recess of the socket has the plug inserted therein. 
   
   
       5 . The connector structure according to  claim 4 , wherein an intermediate connector is disposed between the socket and the plug, the intermediate connector being joined to the socket while an upward-opening recess of the intermediate connector has the plug inserted therein.
