Description

  The present invention is mainly to serve by extruding a viscous or semi-solid food such as soft cream, ice milk, frozen yogurt, whipped cream, mousse, bavaria, etc. stored in a frozen state into a container such as corn or cup. The present invention relates to a single-use type extrusion container.

Conventionally, as an extrusion container of this type, for example, in the food packaging body disclosed in Japanese Patent Application Laid-Open No. 2002-179180, the body has a cylindrical shape, a truncated cone shape, or an inverted truncated cone shape, and has an extrusion hole sealed at the approximate center of the bottom plate. In addition, a configuration is known in which a viscous or semi-solid food is filled in a soft material container formed by providing downward legs on the outer peripheral side of the extrusion hole, and the upper end opening is sealed. ing.
In the above-mentioned extrusion container, since the leg portion is provided, the bottom surface of the container filled with food is not directly installed, which is excellent in terms of hygiene, and the container after use does not become flat and bulky The results are reasonable.
On the other hand, in Japanese Patent Application Laid-Open No. 2002-19852, a double container comprising an outer container made of a plastic sheet and a plastic film of an inner container that is closely polymerized in the outer container sheet, the lid shape being joined to the upper surface of the double container. A structure is disclosed in which the ice cream is discharged from the opening at the bottom together with the content by pressing the plastic film of the ice cream, and the ice cream filled in the double container is an external substance other than the container or the outside air It can be extruded in a non-contact manner.
However, in the above configuration, the plastic sheet of the outer container and the plastic film of the inner container are intimately polymerized. The lid-shaped plastic film is heat-welded and is wrapped so that it can be integrally wound with the plastic film of the inner container. Therefore, when extruding, the flange of the inner container is completely connected from the flange of the outer container. If it is not peeled off and separated, the ice cream cannot be pushed out with the lid and the inner container integrated, and the outer container is not compressed and remains in its original shape. There was a problem of being bulky because it remained in shape.
Further, since the extrusion direction is limited to one side, it cannot be changed during molding.
