BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for taking out a liquid, such as a detergent, for setting a container for containing a liquid and taking out contents from the 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 synthetic resin bag containing a refill detergent is placed upside down in an empty container, and a pump member for taking out liquid is provided at the upper end of the container. The tip of the suction tube projecting downward from the needle is pierced into the bag, and the knock portion having the liquid take-out nozzle at the upper end of the pump member is moved up and down to suck the detergent in the bag from the tip of the suction tube and take out the liquid. Taking out from a nozzle is also considered.

[0005]

However, the bag is made of synthetic resin and has flexibility, and when the user pierces the tip of the suction tube protruding downward from the pump member into the bag, the bag must be pierced at once. There was a problem that the liquid inside spilled out, and it is ideal to pierce it in the center, but there was a problem that it was difficult for a person who was not used to it.

[0006] The present invention solves such a problem, and an object thereof is to allow a user to easily pierce a bag with a suction tube.

[0007]

In order to solve this problem, the present invention provides a pump member having a suction tube for piercing a flexible storage bag placed inside the container from above. A container for taking out liquid or the like attached to the upper end opening of the pump member, in which the pump member is raised so that the tip of the suction tube does not pierce the storage bag, and the pump member is lowered so as to pierce the storage bag. A cylindrical body that guides vertically between the two is provided at the upper end opening of the container.

[0008]

With this configuration, the suction tube is guided by the tubular body and pierces the bottom of the storage bag by tapping the pump member from above to lower it by using the tubular body provided on the lid as a guide. . Therefore, the user can safely and easily pierce the suction tube with the suction tube.
