Description

  The present invention relates to a packaging pack for easily packaging articles to be packaged such as goods and valuables, and a method for manufacturing the same, and is lightweight, low-cost, sufficiently effective in protecting contents and facilitating disposal. For the purpose.

  In particular, when selling products such as watches, glass products, ceramics, etc. that are damaged by dropping, or products that dislike vibration during transportation, such as computers and other measuring instruments, the entire product and other items are wrapped and impacted with a certain thickness. Is packaged by a packaging material capable of buffering.

  As a packaging material for such an item, for example, a container that is considerably larger than the entire item to be accommodated is generally prepared, and the item is placed in the container, and a foamed polystyrene resin piece or the like is placed in the gap in the container. Packing is performed by filling the cushioning material. As an alternative to the above-mentioned expanded polystyrene resin piece, there is also known one that uses a bag body into which a fluid having an amount that does not reach the maximum capacity is injected and sealed as a cushioning material (see JP 2000-53167 A).

  Furthermore, a cold seal adhesive layer is formed on the peripheral edge of at least one surface of a paper sheet material that has cushioning properties and can be folded in two or more folds. There is also known a packaging material for packaging an object to be packaged (see registered utility model No. 3058285).

Furthermore, as for packaging a plurality of products, a pair of stretch films stretched by tensioning a plurality of items to be packaged into the opening of the housing recess of the hard container are stretched and deformed by the items to be packaged, There is also known a package that can hold an object to be packaged in a hollow position of the storage space while maintaining the state (see Japanese Patent Laid-Open No. Hei 8-183564).

  However, when using a foamed polystyrene resin piece as a cushioning material, a bag body in which fluid is injected / sealed (Cited document 1), or a packaging material described in Patent Document 3, a relatively large cushioning effect is obtained, Since the packaging material itself is bulky, it is inconvenient for disposal after use. Moreover, in the packaging material of patent document 2 using the paper-made sheet | seat material which has the cushioning property which can fold in more than two folds which formed the cold seal adhesive bond layer in the peripheral part, it is not bulky, On the other hand, it is buffering effect However, this is not always sufficient.

  Therefore, in the present invention, a sufficient packing space is ensured between the packaged items and the cushioning effect is increased, and there is no bulk before and after use, and the packaging pack is easy to dispose. Specifically, the invention according to claim 1 is a flexible bag body made of a pair of front and back non-permeable sheets, and the bag body has a non-front and back surface. The present invention relates to a packaging pack, wherein the air-permeable sheet is composed of a sealed double sheet that can be inflated via an air valve.

  The invention according to claim 2 relates to the packaging pack according to claim 1, wherein the bag body has a cylindrical shape and is open at least on one side. The invention according to claim 3 relates to the packaging pack according to claim 1, wherein the air valve is provided with a check valve mechanism.

  Further, the invention of claim 4 is a step of obtaining a pack material by cutting a flexible long material made of a non-permeable sheet formed in advance in a cylindrical shape in a crossing direction with respect to the length direction at regular intervals. And folding the pack material in half from the center in the width direction and folding the double sheet in two stages, and projecting one end to the outside at the end of the double sheet on at least one side of the folded pack material And a step of arranging the air valve with the other end facing the back of the double sheet and a step of heat-sealing with the air valve along the cut end surface of the double sheet folded in two steps The present invention relates to a method for manufacturing a medical pack.

  Furthermore, in the invention of claim 5, the step of arranging the air valve is performed before the step of folding the pack material in half in the width direction from the center and folding the double sheet in two stages. It relates to the manufacturing method of the packaging pack as described in above. Furthermore, the invention of claim 6 relates to a method of manufacturing a packaging pack according to claim 4, wherein the air valve is provided with a check valve mechanism.

  According to the first to third aspects of the present invention, the package body is inflated in three dimensions by simply filling the space between the sealed double sheets by the air valve after the package object is put in the bag body, and at the same time, Since the object is held in the middle of the inflated bag body, the buffer protection effect is sufficient, and if the bag body itself is rich in cosmetics, it is not necessary to wrap the packaged article with decorative paper Resource saving and packaging work can be shortened.

  Moreover, after use, it can be flattened by removing the air inside, the bag itself is not bulky before and after use, can be easily disposed of, and can be reused. Very good.

  According to the inventions of claims 4 to 6, since a flexible long material made of a non-permeable sheet formed in advance in a cylindrical shape is used, there is no risk of air leakage because the heat seal portions do not overlap. And the number of heat-sealing work steps in the production line is small, and packaging packs can be mass-produced extremely rationally.
