Description

  The present invention relates to a synthetic resin bag body with a palm portion that maintains the shape of the bag in a hexahedron.

  As a bag body for storing a cosmetic facial mask, toilet aid, etc., as shown in FIG. 10, gusset films 4 are interposed on both sides between the front and back body films 1a and 1b, and side seals 2 are provided. There is provided a synthetic resin bag body with a palm portion that is horizontally placed with the palm portion 3 extended from the body films 1a and 1b as a content outlet.

  Even if this synthetic resin bag with a palm portion is filled with the contents to maintain the solid shape, the rigidity of the film itself is strong, so there is a limit to holding the solid shape, and the corners of the bag body are rounded. Even if it takes an elliptical shape and can protect the contents, it is extremely difficult to maintain an angular three-dimensional shape composed of a hexahedron that exhibits an aesthetic appearance when displayed at a store or the like.

  As disclosed in Patent Document 2 for a bag body that retains a three-dimensional shape, there is provided an invention in which a mold member such as paper is loaded in the bag body in order to retain the three-dimensional shape.

Since this is loaded with a mold member made of paper or the like in a bag body, a very complicated manufacturing process is required, and there is a problem that cost and quality are difficult to be uniform.
