It is a type that the user puts a mouth into the spout and sucks it. The amount of contents to be stored is 100 to 500 grams, and the most planned content is 200 to 300 grams. As the shape of the pouch C, generally, the stand type and the gusset type are often used, and the materials thereof are paper, plastic films, materials such as metal foils, and for the purpose of improving the physical properties of these materials, Other materials are applied, processed by vapor deposition or the like, or those that have been subjected to use are used, each of which is used alone or a material in which these are laminated.

The basic material of the pouch C is often composed of a base material, a barrier material for protecting the contents, and an inner surface material having heat sealability. The substrate is selected from materials having printability, strength, heat resistance, etc., and is preferably a stretched film formed by forming a resin such as various thin papers, polypropylene, polyester, and polyamide, and as a barrier material. A film formed of a polyvinyl alcohol resin, a barrier film such as a film formed of a resin formed of a saponified product of an ethylene-vinyl acetate copolymer, a metal foil such as aluminum, and vinylidene chloride on the above various films. A film provided with a moisture-proof coating such as that described above, or a film in which a metal alone or an oxide such as silicon or aluminum is directly deposited on a base film without using a separate film as a barrier material may be used. In addition, as the heat seal material, a material that does not impair the taste and the like of the contents and has the necessary strength as a pouch is selected. For example, low density polyethylene,
Examples thereof include linear low-density polyethylene, polyolefin polymerized using a metallocene catalyst, and an ethylene-vinyl acetate copolymer. However, the material of the heat seal layer must be heat sealable for assembling the pouch and must be a material that can be thermally bonded to the bonding surface of the spout body. In this case, it is necessary to confirm mutual adhesiveness.

According to the present invention, as described above, a stand-type or gusset-type pouch or the like, or a flat pouch or the like with a cut edge or corner is provided with a lid sandwiched between two sides. It is a spout. As described above, the spout body A of the present invention includes the elongated boat-shaped flange portion a, the adhesive base b, and the spout tube portion c.
