Description

DETAILED DESCRIPTION OF THE INVENTION The present invention forms a self-supporting container from a sheet-like packaging material with one side made of plastic and the other side made of aluminum foil, and also allows the contents such as juice to be transferred into the container during the molding process. This invention relates to a filling packaging machine.

In general, filling and packaging machines that fill containers with contents can be broadly divided into container supply types that fill the contents into pre-formed containers, and those that form containers from flexible sheet-like packaging materials and fill the contents at the same time. There is a container-forming type.

Compared to the container supply type, the container forming type is advantageous in terms of space and overall efficiency because it does not require a separate dedicated machine for forming containers, and is therefore widely used.

Container forming molds have evolved from pouches (bags) with three- or four-sided seals, and recently, self-supporting pouches with gussets formed on the lower side have been provided. This free-standing pouch is superior to conventional pouches in terms of securing capacity, appearance, and ease of use, but since the gusset is formed only on the bottom, the free-standing direction is restricted, and it can be held upside down. I couldn't force it. Therefore, when stacking them or storing them in a refrigerator or the like, it is necessary to align them vertically, which is inconvenient.

Furthermore, if a gusset is formed only on the lower surface and the straw is filled with a gusset or the like, the surface into which the straw can be inserted is limited, which poses a problem in terms of ease of use.

The present invention was made in view of the above-mentioned conventional problems, and its purpose is to form a gusset on both the upper and lower parts of the container, thereby making it possible to stand on its own when standing upright or upside down. By effectively arranging guides and sealers to form this self-supporting container, and by devising the position of the filling nozzle, filling packaging can be made extremely compact and inexpensive. We are here to provide you with a machine.

Embodiments of the present invention will be described below with reference to the drawings. In the examples, a case will be described in which a container is formed using a sheet-like packaging material that has been sterilized in advance.
