Description

The present invention relates to a water server. More specifically, the present invention relates to a water server using a liquid container that contains a beverage liquid.

In this type of water server, Patent Document 1 “Water Server” is known as one that uses a needle-type opening device as means for opening a liquid storage container. The needle of the needle-type opening device can supply water by exposing the opening below the needle head into the plastic bag with the liquid container (plastic bag) opened.

Japanese Unexamined Patent Publication No. 2011-46446 “Water Server” No. 316948 Registered Utility Model Bulletin “Needle in Water Server”

In Japanese Patent Application Laid-Open Publication No. 2011-46446 “Water Server” of Patent Document 1, referring to FIG. 7, a needle-type opening device is provided in a storage chamber of a liquid storage container (plastic bag) filled with a beverage liquid. The bottom is equipped with a needle in an upright state.
By loading the plastic bag into the storage chamber, the plastic bag comes into contact with the bottom surface of the storage chamber, so that the needle protrudes into the plastic bag and opens the plastic bag.
Therefore, when the plastic bag is not loaded, there is a risk of injury to the user because the needle head of the needle 2 is exposed upward from the bottom surface 11 of the storage chamber.

In order to avoid the above-mentioned danger, in the utility model publication “No. 316948” of Patent Document 2 “Needle in water server”, the needle head of the needle is always positioned below the bottom surface of the storage chamber by the elastic force of the spring. It is maintained in an unexposed state (see FIG. 8).
In opening the plastic bag, the needle is raised by pushing up the collar 101 of the needle against the elastic force of the spring 102 so as to protrude from the bottom surface of the storage chamber (see FIG. 9).
In the needle-type opening device, when the tip of the needle rises to a predetermined position, the opening of the needle is exposed in the liquid container and water supply is ensured.
If the needle is not sufficiently raised and does not rise to a predetermined position at the tip of the needle, the opening becomes incomplete (a part of the opening is not exposed in the liquid container), causing water leakage into the device. There is a problem.

Therefore, the present invention provides water supply only when the opening 22 of the liquid container by the tip of the needle is reliable, that is, when the opening 22 of the tip of the needle is completely exposed in the liquid container. The challenge is to make it possible.

The present invention integrally forms a water supply device and a needle-type opening device to relate the vertical movement of the needle head of the needle and the vertical movement of the water supply device, and the needle head and the opening of the needle are connected to the bottom surface of the liquid storage container. A water supply operation of the water supply device is made possible only at a predetermined needle raising position where the protrusion is more completely projected.

The present invention has the effect of allowing the water supply operation only when the needle rises to a predetermined position. When the needle rise is insufficient and the breakage is incomplete, Since the water supply operation is blocked when the position is not located inside the plastic bag, water leakage into the apparatus can be prevented.
