Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the spout of a liquid container, for example, a bag-in-box for a dispenser.

Recently, bag-in boxes have been used in vending machines, but when installing the spout, it is necessary to clean the liquid-contact parts of the spout and connector from a hygienic standpoint.

However, conventional bag-in boxes are not equipped with any means for cleaning the liquid-contacted parts of the spout and connector.

For this reason, the conventional bag-in box has a problem in that it is not possible to keep the parts in contact with liquid sanitary.

The present invention was developed to solve the above-mentioned problems. A connector is connected to a spout body with a membrane stretched over the beverage spout, and a valve seat hole communicating with the spout is provided in the connector. A valve stem for opening and closing is provided, an inlet for a cleaning liquid is provided, the valve seat hole is located in the center of the inlet, a check valve is provided for the outlet for the cleaning liquid, and the tip of the valve stem is provided. A piercing blade that pierces the membrane body is formed on the membrane body.

According to this proposal, when installed in a vending machine, the cleaning liquid can flow through the cleaning liquid inlet with the valve stem closing the valve seat hole. Not only is it hygienic because the valve seat hole is not closed by the valve stem, the beverage flows out from the beverage spout through the flow path that has already been cleaned. Until it is installed in a vending machine, the spout is closed by the membrane and the seal is maintained, and when it is installed in a vending machine, it can be opened with the piercing blade of the valve stem, and when it is in an open state. The valve seat hole is closed by the valve stem, so it can be handled hygienically.

The embodiments shown in the drawings will be described below.

1 is the spout body, which is connected to the container body 2 by the flange.
A membrane 3 is attached to the beverage spout 1a.

Reference numeral 13 denotes a connector attached to the spout main body 1, which has a valve seat hole 4 communicating with the spout 1a.
There is a valve stem 5 that opens and closes this.

The valve stem 5 is always biased by a spring 7 in a case 6 that projects from the connector body in a direction that moves the valve 5b away from the valve seat 4a.

Further, an inlet and an inlet for cleaning liquid are provided with the valve seat hole 4 in between, and 8 is the inlet, a check valve 9 is provided, and 10 is the outlet.

Furthermore, there is a piercing blade 5a at the tip of the valve stem 5, which is designed to pierce the membrane 3.

A push rod 11 that can press the head of the valve stem 5
can be inserted into the case 6 through the single-letter-shaped through hole 12 of the case 6, and is locked by engaging the claw 11a of the push rod 11 in a direction perpendicular to the through hole 12.

Although the embodiment shown in FIG. 4 is different from those shown in FIGS. 1 and 2, they are functionally the same.

Since the present invention is constructed as described above, when the connector 13 is attached to the spout body 1 of the bag-in box and the head of the valve stem 5 is pressed using the push rod 11, the membrane body 3 is connected to the membrane body 3 by the piercing blade 5a. is broken, valve stem 5
With the valve 5b seated on the valve seat 4a, the push rod 11 is locked, and the cleaning liquid flows from the inlet 8 to the outlet 10 to clean the liquid-contacted part of the connector. Next, when the push rod 11 is removed, it can be removed from the valve seat 4a, allowing the liquid in the container to flow out through the spout 1a and the outlet 10. Of course, when draining the container, the container is turned upside down so that the content liquid flows out due to its own weight, but the outflow port 10 is connected to a pump or the like to quantitatively draw out the content liquid.

Since there is a check valve 9 at the liquid outlet, the liquid does not flow out from the inlet 8.

In order to stop the flow of the content liquid, the push rod 11 is inserted again and locked, so that the valve 5b of the valve stem is seated on the valve seat 4a and the flow path is blocked.

In such a state, cleaning can be performed in the same way as before, so the flow path for the liquid content can be cleaned cleanly and kept sanitary at all times.
