Nutrients, drinks, etc.) for a pouch stopper.

[Conventional technology]

Disinfectants and chemicals used in hospitals and the like are often enclosed in pouches having a laminated structure in which different types of resin materials are layered. When using, cut the upper end or one corner with scissors, or tear it by hand from the end cut to take out the solution and use it.When not using all, use the hole drilled on one side of the upper end to project the protrusion of the stand etc. Hang it on the wall to hang it, or pinch the opening with scissors to save.

Such pouches cannot be placed upright because the outer frame is not rigid like boxes and bottles, but in recent years, some pouches have been devised at the bottom to make them stand on a flat surface. .

[Problems to be solved by the device]

When using the solution in the pouch, there is no problem when it is used all at once, but it should be used in small amounts, and the rest should be stored so that the solution inside does not spill. In particular, it is inconvenient to store and carry the pouch that has been opened and used and that contains the remaining residue so as not to spill. Further, when the pouch that has been opened is stored, it is difficult to store not only the disinfectant solution or the medicinal solution but also the drink, etc., because it is possible that contaminants and foreign substances are mixed in the remaining solution.

This invention was made to solve such a problem, and at the time of its purpose, the fluid in the pouch can be dispensed so that the solution inside does not spill when storing the rest of the pouch once opened. Another object of the present invention is to provide a stopper for a pouch, which can be stored in a container, prevents contamination of foreign bacteria and foreign substances in the residual liquid, is convenient to carry even after opening, and can be aseptically operated by using a sterilized stopper.
