Description

The present invention relates to a compression bag capable of compressing a stored object by degassing the stored object in a stored state.

Conventionally, a compression bag that can store an object to be stored such as a futon or clothing in a compressed state is known. The compression bag has a structure in which the gas inside can be extracted (degassed) to the outside while the stored object is stored. As a method of use, the stored object can be compressed by first storing the stored object in a compression bag and then forcibly reducing the internal pressure by compressing it with a vacuum cleaner or by hand. By using a compression bag, the volume of the items to be stored is compressed to about 1/2 to 1/3, so that the storage space for them may be small, and more storage space with the same volume can be stored. You will be able to store the stored items.

For such a compressed bag, technological development is underway for the purpose of easy storage, easy degassing, and further compactness of the stored object. Patent Document 1 describes a resin bag body in which an opening for storing stored items is formed on one edge of the outer peripheral edge, a bite tool provided on the inner surface of the bag body and closing the opening. A compression bag with a degassing portion provided with a resin degassing portion for discharging air inside the bag body, and the degassing portion and the bag body are welded at the base end of the degassing portion. A compression bag with a degassing portion is disclosed, wherein the degassing portion includes a backflow prevention means for preventing backflow of air inside the bag body.

Until now, compressed bags were supposed to be used by consumers at home, but for example, if the items to be stored (commodities) are stored in compressed bags and transported from the stage of manufacture, transportation costs can be reduced. You can expect it. In addition, if the products are stored and displayed at the store as they are, many products can be stored and displayed in a narrow space, and the products will not be soiled. In addition, when the consumer purchases the product, it does not have to be repackaged, and of course, the capacity when the consumer carries it can be reduced.

However, although the capacity of the product is smaller, the thickness is basically only thinner, so the size when the consumer carries the product does not change so much. In addition, it is necessary to pick a flatly compressed product with a finger or hold it with an arm, which causes a problem that it is difficult to carry.

Therefore, an object of the present invention is to provide a compressed bag that can compactly store an object to be stored and can be easily carried.
