Description

  The present invention relates to a refill pouch container for storing toiletries such as liquid detergents, softeners, shampoos and rinses, foods such as cooking oil and instant coffee.

  Toiletries such as liquid detergents and softeners, and foods such as edible oil and instant coffee are 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. It is often done.

  For example, a special container for liquid detergent needs to be weighed and taken out each time it is used, so a rigid plastic container with a nozzle at the spout is easy to pour into a lightweight cup. It is used as a dedicated container.

  The dedicated container that is used repeatedly is designed so as to be easily poured out, so that the convenience of the refilling operation for replenishing the contents from the refilling container is not necessarily considered. In particular, when the mouth of the dedicated container is narrow, it may be difficult to insert the spout of the refill container. The refill container set described in Patent Document 1 has been made in order to solve such a problem, and is a set of a refill container and a refill container provided with a cap adapted to the plug. .

  In the refill container set described in Patent Document 1, the flange portion of the cap is used as a reinforcing member for the container collar in order to improve gripping stability when opening the cap of the refill container. There is a feature.

  However, since the refill container described in Patent Document 1 uses a plug member that is a plastic molded product, it must be expensive. Moreover, when discarding, it may be necessary to cut off the plug portion.

  On the other hand, in a general refill container that does not use a plug member, in order to reduce the cost as much as possible, as a result of reducing the thickness of the material used to the limit, the rigidity of the container is lowered and the container is held by hand. There was a problem with the gripping property. When the container is unopened, the contents will not leak even if it is squeezed firmly, but once it has been opened, the contents will erupt if it is squeezed strongly. The point was not satisfactory.

  The cause of this problem is not only the material thickness problem, but also the container structure. In a general refill container, two opposing laminates and three laminates of bottom members are used to seal the sides of the two opposing laminates and extend this side seal. In general, a top seal portion and a spout are formed.

  With such a structure, the shape of the package filled with the contents becomes a shape similar to that of a triangular pyramid with an upper concavity, so that it is easy to slip and easily slip off when held by hand.
