Description

  The present invention relates to a refill container for storing toiletries such as liquid detergents, softeners, shampoos and rinses, foods such as edible 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, 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 to make it easier to pour into a measuring cup. Used as a container. In order to reduce the cost as much as possible, a flexible container made of a flexible packaging film is generally used as a refill product for replenishing the contents of the container.

  As a refill container, it is easy to take out the contents, and it is required to take out the contents while maintaining a stable flow until the end. Conventionally, a hollow cylindrical nozzle made of synthetic resin or the like is previously provided in the spout portion. Have been proposed (Patent Document 1), and a space portion serving as a pouring path formed in advance in a shape in which the film of the spout portion is raised (Patent Document 2).

  However, in the case of the container described in Patent Document 1, a special process for adding a nozzle in the manufacturing process of the container is necessary, which causes an increase in cost. Moreover, in the container described in patent document 2, there existed a fault in which the extraction | pouring part is easy to bend and the extraction path | route through which the content passes at the time of extraction will become unstable.

  That is, if the depth of the embossed part is too small, the container in which the flow path is formed by forming a plurality of recessed embossed parts at the base part of the spout will block the flow of the contents and conversely If it is too large, the flow path is sufficiently secured, but the base part of the spout of the obtained container is deformed, and the packaging becomes unstable or the suitability of the filling and packaging machine is deteriorated.
