  As shown in FIGS. 1 and 2, the container 1 of the present invention is attached to a main body 2 for storing a liquid content such as a jelly-like food, and attached to the vicinity of the center of the upper end portion of the main body 2. It consists of a spout 3 for pouring the contents in the main body 2 and a lid portion 4 of an assembly formed integrally with the spout 3.

  The main body 2 is, for example, a stand pouch (which may be a flat pouch or a gusset pouch) having an opening formed of a laminated film having a barrier property, and the configuration thereof is a surface layer / sealant layer or a surface layer / Layered like an intermediate layer / sealant layer. The surface layer and the intermediate layer may each be a single film layer or the like, but may be composed of two or more types of multilayers. In addition, an adhesive layer can be provided between the above layers as necessary.

  The surface layer is excellent in printability and laminating properties, and has excellent overall mechanical strength such as tensile strength, impact strength, and scratch resistance, as well as solvent resistance, chemical resistance, and resistance to heating during heat sealing. Heat resistance is required.

  Examples of such a film include a biaxially stretched polyester film, a biaxially stretched nylon film, and a biaxially stretched polypropylene film, as well as polyvinylidene chloride (PVDC) for imparting moisture resistance and gas barrier properties thereto. The film etc. which coated these etc. are mentioned, These can be used individually or by laminating | stacking 2 or more types. The thickness of such a surface layer is preferably in the range of about 9 μm to 50 μm.

  The intermediate layer is provided to improve the mechanical strength of the laminated film, or to improve water vapor and various gas barrier properties. For example, nylon, polyvinyl alcohol, ethylene-vinyl acetate copolymer may be used depending on the purpose. A film such as a saponified product (EVOH), an aluminum foil, or a resin film having a surface coated with a thin film (thickness 400 to 600 angstrom) such as aluminum, silicon oxide, or alumina by vacuum deposition or the like is used. The thickness of the intermediate layer is usually preferably about 7 to 50 μm.

  When the intermediate layer is prepared in the form of a film in advance, the intermediate layer is laminated on the surface layer by using a conventionally known dry lamination method or a heat adhesive resin such as polyethylene between the surface layer and the intermediate layer. It can be laminated by an extrusion lamination method in which it is extruded from a T-die to be bonded and bonded. Further, when the material of the intermediate layer is a resin such as pellets, the surface layer film is extruded and laminated, or once formed into a film by inflation molding or the like, and this is the dry lamination method or They may be laminated by an extrusion lamination method or the like.

  In addition, when laminating the intermediate layer on the surface layer film, the surface of the surface layer is subjected to corona discharge treatment for stabilization of adhesion, and further known as organic titanium, urethane, imine, rubber, etc. An anchor coat can also be applied.

  Next, the sealant layer is provided in the innermost layer of the laminated film, and when the laminated film is produced, it is necessary to thermally bond with sufficient strength by the heat and pressure of the sealer. In addition, the sealant layer needs to be heat-welded with the material of the spout 3 and is also in the innermost layer of the bag and directly contacts the contents to be filled, so that the content resistance is also required.

  Such sealant layers include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), polypropylene (PP), ethylene-vinyl acetate co-aggregated resin (EVA), and ethylene-acrylic acid copolymer resin (EAA). Polyolefin resins such as ethylene-ethyl acrylate copolymer resin (EEA), amorphous polyester, and ionomer can be used. From these, select the appropriate one according to the material of the spout 3 and the type of contents. Can be used.

  The sealant layer can be laminated by extruding and coating the resin as described above on the surface layer or the inner surface side of the film in which the surface layer and the intermediate layer are laminated. Can also be laminated by a dry lamination method or the like. In this case as well, pretreatment such as corona discharge treatment or anchor coating can be applied to the laminated surface in order to stabilize the adhesion.

  Therefore, the main body 2 is thermally bonded in the shape of a ship-bottom bag by hanging the laminated film produced as described above on a bag making machine, or a bag making and filling machine (a machine that performs bag making and filling and sealing inline). Let's create. The main body 2 is not limited to the stand pouch type as shown in FIG. 1, but may be a flat pouch type as shown in FIG. 2, and can also be applied to a gusset pouch type not shown. In the present application, FIG. 2 and subsequent figures will be described as a flat pouch type.

  Next, the spout 3 and the lid 4 are either polypropylene (PP), low density polyethylene (LDPE), linear ultra low density polyethylene (LLDPE), high density polyethylene (HDPE), or a blend of these. It can be made of a resin material. And as shown in FIGS. 3-4, the spout 3 is a hollow cylinder member whose outer shape has an elliptical shape (not limited), and is located in the inner peripheral edge 2a opened at the upper end of the main body 2, and this It is comprised from the inner side attachment part 3a fixed to the inner peripheral edge part 2a by heat sealing etc., and the outer side cylinder part 3b located in the outer side of the main body 1. FIG.

  On the other hand, the lid 4 is a cap of the spout 3 having the same elliptical outer shape as that of the spout 3, and the upper end 3c of the spout 3 is protruded inward to facilitate breakage, which will be described later. Integrated with the spout 3 via the part 5 by injection molding or the like (at the time of molding, the lid part 4 continuously provided around the upper end of the spout 3 via the thin part 5 serves as the opening of the spout 3 It is an intermediate part of the lid 4 and protrudes outward at the upper end of the joint with the spout 3 so that it can be detachably attached to the spout 3 A protrusion 6 is provided.

  Therefore, in order to pour out the contents contained in the main body 2, when the container 1 is initially opened, the inner mounting portion 3 a of the spout 3 is sandwiched between the fingers and pressed, and the lid 4 with the opposite hand. As shown in FIG. 5, the thin portion 5 is broken and the lid portion 4 is peeled from the spout 3, and the contents can be taken out from the spout 3. On the other hand, when attaching the lid part 4 to the spout 3, as shown in FIG. 6, the lid part 4 is fitted along the spout 3 from above and pressed, so that the protruding part 6 of the lid part 4 is formed. By getting over the thin portion 5 of the spout 3, both are fitted and fixed, and the lid 4 is detachably attached to the spout 3.

  Next, the container 1 of this invention provides the through-hole 7 in the cover part 4 first. As shown in FIGS. 3 to 4, the through-hole 7 has a shape (not limited) such as a circle formed near the center of the lid portion 4, and is configured to communicate with the spout 3.

  Further, the through hole 7 is sealed on the upper surface of the lid portion 4 by the laminated film as described above having the sealing performance welded by heat sealing as the closing means 8. The closing means 8 is not limited to the above, and for example, a film or sheet (the material is not limited as long as it has a sealing property) or the like is welded to the upper surface of the lid 4 by heat sealing or ultrasonic sealing. Alternatively, the through hole 7 can be sealed by a known technique such as fitting a molded part made of the resin as described above into the through hole 7 or the lid portion 4.
