Description

  The present invention relates to a refill container for storing toiletries such as liquid detergents, shampoos and rinses, foods such as edible oils, seasonings and instant coffee.

  Toiletries such as liquid detergents and shampoos, and foods such as edible oils, seasonings, and instant coffee are each stored in dedicated containers that are easy to use. The dedicated container has a solid structure and is therefore expensive, so a product with a refill container that refills only the contents is sold separately so that it can be used repeatedly when the contents are gone. There are many.

  For example, liquid detergent containers need to be weighed and taken out each time they are used, so a rigid plastic container with a nozzle at the spout is repeatedly used so that it can be easily poured into a lightweight cup. Used as a container. In contrast to this container, as a refilling container for replenishing the contents, a flexible container made of a flexible packaging film, a container in which a spout is formed, or a container attached with a stopper is generally used. ing.

  Since the rigid container to be used repeatedly is designed to be easily poured out, considering the convenience in the refilling operation of replenishing the contents from the refilling container to the container to be used repeatedly, Not necessarily.

  On the other hand, the refill container is not always in consideration of the convenience in the refilling operation, because the emphasis is on manufacturing inexpensively.

  From the viewpoint of cost, a packaging bag formed by simply sealing the periphery of two front and back packaging films as shown in FIG. 8 is advantageous. This refill packaging bag can be provided with a spout having an arbitrary width corresponding to the caliber of the container. However, when the spout is formed by sealing the edges of the two front and back films, When the product is poured out, the opening is pulled at both ends sealed, the front and back films are in a pseudo-adherent state, and the spout is clogged, and the spout is likely to bend in the lateral direction. There is a problem that the spout is detached from a container that is repeatedly used. Moreover, since the opening width of the spout is a width excluding the seal portions on both sides of the spout, there is a problem that a sufficient opening width cannot be obtained and a sufficient amount of pouring cannot be secured.

  The packaging bag with an opening maintaining sheet described in Patent Document 1 is a product in which a part separate from the film is inserted into the spout part in order to solve the problem that the spout is blocked or bent. is there.
