Description

  The present invention relates to a bag-like container for storing liquid detergent, shampoo, and the like, and more particularly to a bag-like container having a dispensing function for refilling the contents into another container.

In recent years, due to environmental problems related to the increase in waste, the peripheral edges of two or more layers of packaging materials based on plastic film are thermally bonded for the purpose of saving resources and reducing waste, such as liquid detergents and shampoos. A bag for storing the product, cut a predetermined position of the extraction portion protruding in use with a scissors or the like to provide an outlet, and easily pour the contents from the outlet into, for example, a plastic bottle with a pump-type dispenser, A large number of refill bags with a dispensing function that can be refilled (mostly self-standing pouches) are being used. As the refill bag with the above-described dispensing function, it is required that the contents can be poured out while maintaining a stable flow until the end. Various types of such refill bags have been proposed, and those provided with a pour-out portion protruding from the refill bag have been proposed (see, for example, Patent Document 1).
JP 11-130105 A

  However, the above-mentioned proposal has drawbacks such as difficulty in pouring the contents when the contents are a high-viscosity liquid.

  An object of the present invention is to solve the above-mentioned problems, and when refilling high-viscosity contents into another bottle or the like, the contents can be stably poured out, and a bag-like container with a pouring function that can be refilled Is to provide.

The invention according to claim 1 of the present invention is composed of a laminated material having at least a base material layer and a sealant layer, rises with a uniform width from the bottom surface, and has a distal end direction along the upper side that is narrowed at the upper end. In a bag-like container with a pouring function in which a pour-out path for convex contents is continuously provided, an opening is provided at one end of the upper side, and the remaining peripheral edge is sealed, the pour-out path is a hollow four-dimensional view in a longitudinal sectional view. It is a prism or triangular prism, and has a shape in which both the top surface and bottom surface, or the bottom surface or top surface are folded inwardly into a V shape through a crease substantially parallel to the upper side. It is a bag-like container with a dispensing function.

  The bag-like container with a pouring function of the present invention is made of a laminated material having at least a base material layer and a sealant layer, rises with an equal width from the bottom, and has a convex shape in the tip direction on the body having a narrow upper end In a pouch-shaped container with a pouring function in which an object pouring path is continuously provided, an opening is provided at one end of the upper side, and the remaining peripheral edge is sealed, the pouring path is a top or bottom surface or top surface of a hollow rectangular column Since the bottom surface is folded in a V shape inside, the contents can be removed from the spout by cutting the pouring path at a predetermined position to refill the contents and providing a wide spout. Can be refilled efficiently.

The bag-like container with the dispensing function of the present invention will be described below along the embodiment. Fig.4 (a) is a sectional side view which shows one Embodiment of the laminated material used for the bag-like container with the extraction | pouring function of this invention, and laminated material (30) is a base material layer (41 in order in the thickness direction). ), An adhesive layer (42) and a sealant layer (43) are laminated, (b) is a side sectional view showing another embodiment of the laminated material, and the laminated material (31) is in the thickness direction. The base layer (41), the adhesive layer (42), the intermediate layer (44), the adhesive layer (45), and the sealant layer (43) are laminated in this order.

  For the base material layer (41), a biaxially stretched polypropylene film, a biaxially stretched polyester film, a biaxially stretched nylon film, a moisture-proof cellophane, or the like that is generally used is used. The thickness is appropriately selected.

  The sealant layer (43) is made of a polyolefin resin or a polyolefin resin film. Examples of the resin include low density polyethylene resin, medium density polyethylene resin, linear low density polyethylene resin, and ethylene / vinyl acetate. Laminating method can be used such as ethylene resin such as polymer resin, polypropylene resin such as homopolypropylene resin, propylene-ethylene random copolymer, propylene-ethylene block copolymer, polypropylene-α-olefin copolymer, etc. Are laminated by a known melt extrusion method or dry lamination method.

  The intermediate layer (44) is provided mainly for imparting gas barrier properties or improving various mechanical strengths of the laminated material, and is not particularly limited, and is composed of a single layer or multilayer film. Non-stretched nylon film, aluminum foil, ethylene / vinyl alcohol copolymer film, vinylidene chloride film, polyvinyl alcohol film, acrylic film, etc. are used as a single layer film, and a multilayer film in which the single layer films are laminated. Films, vinylidene chloride resin-coated cellophane, aluminum-deposited polyester films, aluminum-deposited polypropylene films, inorganic oxide-deposited polyester films, and the like are used. Lamination is performed by a known dry lamination method or the like.

Generally, a polyurethane-based adhesive is used for the adhesive layers (42, 45). Usually, a two-component type is used in which a main component having a hydroxyl group and a curing agent having an isocyanate group are mixed in two components. The lamination is performed by a known gravure coating method. The coating amount is preferably 1 to 5 g / m ² (dry state).
