Description

  The present invention relates to a bag such as a bag and a method for manufacturing the bag.

  There are reversible products that can be used even when the front and back are turned inside out, such as clothes such as jackets and hats, and bags such as bags. In addition, reversible products that can be used on the front and back sides are used in various products because the front and back surfaces are formed with different colors, patterns, or materials, and the desired surface can be used as the surface of the product according to the TPO. Yes.

However, the reversible product of the bag is used by turning over the front and back surfaces of the bag body that forms the storage portion (the portion into which the contents are stored). When turning from the front to the back, the contents had to be taken out of the bag. Therefore, the inside-out work is often performed in an invisible place, and there is a problem that the place where the inside-out work can be done is limited.
Further, in the case of a bag made of a hard bag or a bag having a narrow opening for taking in / out the contents, there is a problem that the flipping operation is not easy.
