Description

Refill container plug

The present invention relates to a plug for refilling containers, and more particularly to a plug for refilling containers for refilling the refilled outlet of a refilled container for refilling the contents of the refilled container.

In recent years, containers made of synthetic resins containing various liquids or other contents have also been developed to reduce the environmental load, and various thin-walled containers have been developed which reduce the amount of resin used. Further, as a container for storing various detergents, foods, and the like, a refill container formed of a bag or the like is often used. The refill container can be used for a long period of time by refilling or replenishing the contained contents into the refilled container including the discharge nozzle portion or the discharge portion, and does not discard the expensive refilled container every time.

On the other hand, the refill container formed of a bag or the like is formed of a flexible material which is flexible or flexible, and the container is easily deformed during the refilling operation, and is liable to be extremely unstable. Further, the refilling operation of the contents of the refill container is performed, for example, by the following steps: a) cutting the front end of the nozzle portion; b) obliquely injecting; c) maintaining the tilted state; d) squeezing; Be careful not to spill and discard; but it takes a lot of effort to refill the contents of the work steps, and the contents are easy to spill during the work.

Thus, a refill container has been proposed which reliably connects the refilled outflow port of the container formed of the soft package material to the neck portion of the refilled container, thereby facilitating refilling (for example, refer to Patent Document 1 and Patent Literature 2). In the refill container of Patent Document 1, a plug having a tubular portion having a female thread formed on an inner peripheral surface is attached to the refilled outlet. The female thread of the tubular portion is screwed to the male thread formed on the outer peripheral surface of the neck portion of the refilled container, and the refilled outflow port of the refilled container is coupled to the neck portion of the refilled container.
