  When the liquid filled by contact with the outside air is, for example, a cosmetic liquid used directly on the skin, or a food product such as a sauce, mayonnaise, or cooking oil, quality deterioration due to oxidation, etc., propagation of germs, etc. may occur. There is a fear.

  In addition, since the mouth of the liquid container with the lid removed is open without opening, when the liquid container is tilted or overturned due to unfamiliarity or carelessness when mounting it to the liquid take-out device In some cases, the liquid content was spilled.

  Further, when the liquid container is flexible, the liquid container may be crushed and the liquid may overflow when the non-plugged liquid container is strongly grasped.

  On the other hand, in the technique of Patent Document 3, the opening of the mouth portion of the liquid container is configured not to remove the lid body but to open it by piercing the suction pipe of the pump body into the sheet-like seal body. In the liquid container having such a configuration, it is necessary to join the seal body to the mouth portion after filling the liquid container with the liquid, and the joining of the seal body is expensive.

  Furthermore, since the tip of the suction tube has a sharp shape when the suction tube is pierced, if the user is an elderly person, a woman, or the like, the user may be strongly pierced by striking the weakness of the sharp shape first. There is a problem that unsuccessful opening fails.
