Abstract

Provided is a connector including a plug to be fixed to an inner peripheral surface of an opening of a liquid storing container, and a socket to be detachably attached to the plug. The plug includes a plug body in which a first liquid outflow passage, a first liquid inflow passage, and a first gas passage are formed. The socket includes a socket body including, formed therein, a second liquid outflow passage, a second liquid inflow passage), and a second gas passage; a rotary valve having an outflow through-hole and an inflow through-hole; and a switching mechanism for switching between an open state and a closed state when the rotary valve is rotated.

First claim

What is claimed is:

1. A connector to be attached to a liquid storing container having an opening formed in an upper surface thereof, the opening being formed with a cylindrical shape about a first axial line, the connector comprising:
a plug to be fixed to the opening; and
a socket to be detachably attached to the plug,
wherein the plug includes a plug body including, formed therein, a first liquid outflow passage through which a liquid stored in the liquid storing container is drawn out; a first liquid inflow passage that guides the liquid flowing in from an outside of the liquid storing container into the liquid storing container; and a first gas passage that circulates an outside air between an inside space of the liquid storing container and an outside space of the liquid storing container, and
wherein the socket includes:
a socket body including, formed therein, a second liquid outflow passage through which the liquid drawn out from the first liquid outflow passage is caused to flow to the outside; a second liquid inflow passage that guides the liquid flowing in from the outside of the liquid storing container to the first liquid inflow passage; and a second gas passage connected to the first gas passage and causing the outside air to circulate between the inside space and the outside space, the socket body having a columnar insert hole formed along a second axial line so as to penetrate through the second liquid outflow passage and the second liquid inflow passage, the second axial line intersecting with the first axial line;
a columnar rotary valve including an outflow through-hole and an inflow through-hole and inserted into the insert hole, the outflow through-hole being formed at a location where the second liquid outflow passage is disposed on the second axial line, the inflow through-hole being formed at a location where the second liquid inflow passage is disposed on the second axial line; and
a switching mechanism that switches between an open state and a closed state when the rotary valve is rotated about the second axial line, the open state being a state in which the outflow through-hole and the second liquid outflow passage communicate with each other and the inflow through-hole and the second liquid inflow passage communicate with each other, the closed state being a state in which the outflow through-hole and the second liquid outflow passage do not communicate with each other and the inflow through-hole and the second liquid inflow passage do not communicate with each other.

2. The connector according to claim 1 , wherein
the rotary valve has a first discharge hole and a second discharge hole, the first discharge hole having one end opened to an outer peripheral surface of the rotary valve and the other end opened to the outflow through-hole, the second discharge hole having one end opened to the outer peripheral surface of the rotary valve and the other end opened to the inflow through-hole, and
when the switching mechanism switches the rotary valve to the closed state, the first discharge hole communicates with the second liquid outflow passage below the outflow through-hole, and the second discharge hole communicates with the second liquid inflow passage below the inflow through-hole.

3. The connector according to claim 2 , wherein the socket body has a communication hole for allowing the outflow through-hole and the inflow through-hole to communicate with each other when the switching mechanism switches the rotary valve to the closed state.

4. A socket to be attached to a liquid storing container having an opening formed in an upper surface thereof, the opening being formed with a cylindrical shape about a first axial line,
the socket comprising:
a socket body including, formed therein, a liquid outflow passage that causes a liquid drawn out from a plug fixed to the opening to flow to an outside; a liquid inflow passage that guides the liquid flowing in from the outside of the liquid storing container to the plug; and a gas passage that circulates an outside air between an inside space of the liquid storing container and an outside space of the liquid storing container, the socket body having a columnar insert hole formed along a second axial line so as to penetrate through the liquid outflow passage and the liquid inflow passage, the second axial line intersecting with the first axial line;
a columnar rotary valve having an outflow through-hole and an inflow through-hole and inserted into the insert hole, the outflow through-hole being formed at a location where the liquid outflow passage is disposed on the second axial line, the inflow through-hole being formed at a location where the liquid inflow passage is disposed on the second axial line; and
a switching mechanism that switches between an open state and a closed state when the rotary valve is rotated about the second axial line, the open state being a state in which the outflow through-hole and the liquid outflow passage communicate with each other and the inflow through-hole and the liquid inflow passage communicate with each other, the closed state being a state in which the outflow through-hole and the liquid outflow passage do not communicate with each other and the inflow through-hole and the liquid inflow passage do not communicate with each other.
