Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid take-out member for taking out the liquid inside from a liquid containing bag containing a liquid such as detergent in a separate container. .

[0002]

2. Description of the Related Art Conventionally, liquid detergents and the like used at home are sold in a container made of synthetic resin. For example, when the detergent in the container is exhausted, it enters a synthetic resin bag. I bought a refill detergent and refilled it in an empty container.

However, when the refilling detergent is refilled in an empty container as described above, a flexible bag made of a synthetic resin is held in the hand to carry out the refilling work. There is a problem in that the position of is unstable, it takes time to perform the refilling work by aligning the mouth portion of the container and the mouth portion of the bag, and the detergent spills out of the container when the care is taken.

In order to solve this problem, a stand-pack type liquid storage bag made of synthetic resin containing a refill detergent is placed upside down in an empty container, and a liquid take-out portion provided at the upper end of the container. From the upper end of the liquid take-out member, the tip of the suction tube protruding downward from the liquid take-out member is pierced into the liquid storage bag, and the detergent in the liquid storage bag is sucked from the tip of the suction tube by inclining the container. It is also considered to be taken out.

[0005]

However, the liquid storage bag is made of synthetic resin and has flexibility, and the liquid storage bag is deflated as the detergent is taken out from the liquid storage bag, and is formed by piercing the suction tube. The hole is lowered, and if the suction tube is short, there is a problem that the suction tube will come off from the liquid storage bag, so it is necessary to lengthen the suction tube, but if the suction tube is lengthened, When tilting the container to take out the detergent from the liquid storage bag, if the remaining detergent inside the liquid storage bag becomes low, the suction port at the tip of the suction tube will be exposed from the detergent with the detergent accumulated around the suction tube. There was a problem that the detergent could not be taken out to the end.

The present invention solves such a problem, and an object thereof is to enable the liquid in the liquid storage bag to be taken out to the end even if the suction tube is lengthened.

[0007]

In order to solve this problem, the present invention is a liquid take-out member having a suction tube for piercing a liquid storage bag made of synthetic resin contained in a container from above. The top of the suction tube is equipped with a liquid outlet on the upper end, and when the suction tube is pierced into the liquid storage bag, it is located slightly below the hole formed by the puncture of the suction tube. And the lower end of the suction tube is closed. Further, the present invention is a liquid take-out member having a suction tube for piercing a liquid storage bag formed from a laminated sheet formed by laminating a synthetic resin film and an aluminum foil placed inside a container from above. In addition, a liquid take-out port is provided at the upper end, and when the suction tube is pierced into the liquid storage bag, the suction tube is attached to the outer circumference of the suction tube so as to be located slightly below the hole formed by the puncture of the suction tube. The suction port is formed and the lower end of the suction tube is closed.

[0008]

With this configuration, even if the amount of liquid remaining in the liquid storage bag is reduced, the liquid in the liquid storage bag is finally removed from the suction port located slightly below the hole formed by the puncture of the suction tube. Can be taken out.
