Description of the Related Art A bag body with a synthetic resin chuck, in which a male and female bite type chuck is provided inside an opening of a bag body and lateral gussets folded in a V shape on both sides are adhered, is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 5 (1993) -53. It is known from 97151.

が大きく得られる利点がある。The bag body with a synthetic resin chuck having the above-mentioned known lateral gusset has a length dimension such that the upper edge of the lateral gusset is located below the chuck, and the upper end of this lateral gusset is opened. This is a structure in which the edges are adhesively sealed along the edges, and there is an advantage that the opening width can be increased over the entire width of the opening of the bag.

容容積の減少が避けられない。However, this large opening is limited to the opening of the bag and its vicinity, that is, when the opening of the bag is opened, the opening above the chuck of the bag has a large opening area. Although obtained, the upper edges of the lateral gussets on both sides project and are located in this opening area, and this interferes with the contents when the contents are taken in and out, and hinders smooth contents taking in and out. In order to avoid this interference, it has been proposed in the above-mentioned conventional example to narrow the upper edge of the lateral gusset, but this method cannot avoid a reduction in the storage volume of the contents.

としたことである。An object of the present invention is to provide a bag body with a zipper made of synthetic resin, which is provided with a lateral gusset so that the opening portion of the bag body can have a large opening width over the entire width and a large storage volume of contents can be obtained. The upper edge of the horizontal gusset does not interfere with the contents when loading and unloading the contents, and enables smooth loading and unloading like a normal flat bag with a zipper without a horizontal gusset.

側面に寄せて接着したものである。In order to achieve the above object, the structure of the present invention is such that the lateral gussets folded in a V shape are adhered to both sides of the body film of two front and back sides, and the inner side of the opening is provided. In a bag body with a synthetic resin chuck provided with a male and female bite type chuck, an upper end edge of the lateral gusset has a length dimension located below the chuck, and the upper end edges of the lateral gusset are the front and back body parts. The film is adhered to one of the inner surfaces of the film.

る。A male and female bite type chuck is provided inside the opening of the bag body of the front and back two body films having a heat-adhesive resin layer on the inner surface, and the inner side surfaces are provided on both sides of the bag body. A lateral gusset, which is folded in a V shape with the outer surface inside by a resin film having thermal adhesiveness with the inner surface of the body film, is adhered in such a length dimension that the upper end thereof is located below the chuck. The upper edge of the lateral gusset is brought close to the inner surface of one of the two front and back body films, and is bonded to the inner surface of the body film and the inner surface of the lateral gusset with a sealing tape having heat adhesiveness. It was done.

方の片側のみに寄せて接着することである。Reference numeral 4 denotes a horizontal gusset formed by folding a film into a V shape, which is adhered to both sides 5 of the bag body 1. The lateral gusset 4 has a folding ridge 4a parallel to the side 5 of the bag body 1, and the upper edge 4b of the lateral gusset 4 has a length dimension below the chuck 3. As shown in FIG. 2, the upper edge 4b is a structure in which the upper edge 4b is adhered 4c only to the inner surface of the front body film 1a side. It should be noted that it may be adhered only to the back body film 1b, and in short, it may be adhered to one side of either one of the front and back body films 1a and 1b.
