Description

  TECHNICAL FIELD The present invention relates to a flat pouch having a back-closeable back seal shape that is made of a flexible packaging material for packaging confectionery, frozen foods, and the like.

  In general, as a pouch that is made of a flexible film packaging material for packaging in a pillow packaging form, there is a flat pouch that is back-sealed and made into a bag, and a vertical pouch is formed at the center of one side of the flat pouch. A back seal portion is provided in the direction, and a notch that is a trigger for opening is formed at a predetermined position of the back seal portion, or a fine scratch processing that is a trigger for opening is formed on a part or all of the back seal portion Has been.

  Known techniques related to such a pouch include, for example, Patent Document 1 and Patent Document 2, by picking the position where the back seal portion is desired to be opened with both hands and pulling it in the left and right sides perpendicular to the back seal portion. It can be opened.

  In such a conventional flat back-seal pouch, Japanese confectionery (such as dorayaki) and Western confectionery (cream cake, sticky confectionery, etc.), frozen foods (rice ball, croquette, etc.), solid daily necessities, etc. Contents such as lump solid bodies such as powders, solid bodies such as powders, granules, granules (frozen pilaf, etc.), and liquids such as beverages, liquid seasonings, liquid detergents, etc. When taking out the contents from the pouch, pick the position where you want to open the back seal part with both hands and use the notch etc. formed at the predetermined position of the back seal part as a trigger. By pulling in the left and right sides of the pouch orthogonal to the part, it can be easily opened and the contents taken out.

  However, if the contents of the pouch are a solid body other than a liquid substance, or a solid powder such as powder, granules, granules, etc., after opening the pouch, leave a part of the contents in the pouch. If you want to re-seal, the open side of the opened pouch is rounded or bent into an indefinite shape, or rounded into an indefinite shape so that the solid contents left in the pouch do not jump out of the pouch. It was difficult to reseal because the bent part was fastened with rubber bands.

  For this reason, even a pouch using a relatively flexible film material may be difficult to reseal depending on its hardness, it is difficult to stably hold the contents in the pouch, and it is resealed to an indefinite shape. Therefore, the appearance of the pouch as a container may be impaired.

  In addition, when the contents are powdery, granular, granular, or other solid or liquid, and when you want to open the pouch and pour it into another container, the external shape of the pouch is flat. Since it is a pillow packaging shape and the pouch is made of a flexible film, the pouch is not only difficult to hold by hand, but the opening pour side of the opened pouch is a flexible film, so it is a pouring position. However, it was difficult to take out powder, granule, granule, and liquid contents, and it was difficult to pour out.
