TECHNICAL FIELD The present invention relates to a device for connecting to a tap for supplying liquids, and more particularly to a device for connecting to a tap attached to a spout of a liquid container.

Liquid containers include, for example, a bag-in-box. A bag-in-box is a container mainly used for liquids, and is a combined container composed of a bag-shaped inner container made of plastic or the like and an outer container mainly composed of a cardboard case such as a cardboard case. The inner container main body is provided with a spout for filling and taking out contents.

The spout is fitted with a plug that seals the container and opens and closes it as needed. Various types of plugs are used, such as the cock type, the screw type, and the pull-top type.

The inner container of this bag-in-box filled with soft drinks or alcoholic beverages is used in restaurants and the like. In particular, bottles filled with wine, which is an alcoholic beverage, are called boxed wines or boxed wines.

The stopper based on EP-A-0432070 has a wing-shaped opening mechanism and finger pressure applied to the top of the stopper to allow liquid to be dispensed while the stopper is open. In other words, the stopper had to be operated each time to supply the liquid from the container to which this stopper was attached.

However, in restaurants where the supply frequency per hour is high, it is troublesome to operate the stopper each time the liquid is supplied, and it has been desired to connect the stopper to the dispenser. When connected to a dispenser, since the dispensing is performed on the dispenser side, it is preferable that the container side maintains a state in which the liquid can be continuously supplied. exists (Patent No. 5886951).

Patent No. 5886951

As described above, when connecting a stopper and a dispenser in a restaurant, it is preferable to maintain a state in which the liquid can be continuously supplied, and there are connectors that meet such needs. However, since the conventionally known connector is assembled from a plurality of parts, it needs to be disassembled and cleaned when cleaning.

When cleaning the connector by hand, the connector parts are disassembled. In addition to washing by hand, it is also common to use a commercial dishwasher with a high-temperature water flow. However, when a dishwasher is used to clean such connectors, small parts such as valves are not put into the dishwasher and are washed manually. This is because if all disassembled parts are placed in a dishwasher and washed, small parts remain in the dishwasher, and some parts such as valves are not suitable for high-temperature washing.

That is, no matter which method is used, there is a problem that the troublesome work of disassembling and reassembling the parts is required for cleaning.
