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 provided with a dispensing function for refilling the contents into another container such as a bottle. .

In recent years, due to environmental issues related to the increase in waste, liquid detergents with a dispensing nozzle part protruding outward at a predetermined position on the periphery of a bag made of laminated packaging material for the purpose of saving resources and reducing waste Many packaging bags for refilling such as shampoo and shampoo are used. When repacking the contents of these packaging bags, cut the predetermined position of the pouring nozzle with a scissors or the like to provide a pouring outlet, and pour the contents from the pouring outlet into, for example, a plastic bottle with a pump-type dispenser, There is a need for refills that can be easily poured out while maintaining a stable flow to the end. Various types of packaging bags for such refills have been proposed. A pour-out portion protruding from the corner of the refill bag is provided, and a flow path is provided in the pour-out portion when the contents are poured out. The thing of the structure which provided the reinforcement part so that it may not collapse is proposed (for example, refer patent document 1 and patent document 2).
JP 11-130105 A JP 2003-118744 A

  However, those proposed in Patent Document 1 and Patent Document 2 are provided with a resin portion for reinforcement on the inner surface or outer surface or both surfaces of the pouring portion, and the resin portion is peeled off, making it difficult to pour out. It had problems such as.

  An object of the present invention is to solve the above-mentioned problems, and is a bag-like container with an extraction function for storing contents such as liquid detergent and shampoo, and when the contents are refilled into other bottles, etc. An object of the present invention is to provide a bag-like container with a pouring function that can easily pour out the contents because the pouring passage of the nozzle part is difficult to block.

  The invention according to claim 1 of the present invention comprises a laminated material having at least a base material layer and a sealant layer, has a bottom seal part on one side of the container main body part, and linear side seal parts at both ends of the bottom seal part. And the end of the unsealed side of the bag-like container having the unsealed side on the opposite side of the bottom seal portion is sealed at the peripheral edge and has a one-side bulge height of 1.0 to 5.0 mm on the tip side. A convex pouring nozzle portion having a bulging portion A is provided, and a bulging portion B having a predetermined shape is provided in the container main body portion in connection with the pouring nozzle portion. A hollow portion having a predetermined shape is provided on an extension of the perpendicular bisector in the width direction of the discharge nozzle portion, and the hollow portion is directed from the tip side near the top of the bulge portion A of the extraction nozzle portion toward the bulge portion B side. There must be at least one linear half-cut groove extending immediately before It is a function with a bag-like container pouring and features.

  The invention according to claim 2 of the present invention is characterized in that, in the invention according to claim 1, the linear half-cut groove is formed by engraving through a base material layer of a laminated material. It is a bag-like container with functions.

  Thus, according to invention of Claim 1 and Claim 2, it has the bulging part A with which the periphery is sealed and the single-sided bulging height of the front end side is 1.0-5.0 mm in one corner of a container main-body part. A convex pouring nozzle portion is provided, and a bulging portion B having a predetermined shape is provided in the container main body portion in connection with the pouring nozzle portion. Within the region of the bulging portion B, the width direction of the pouring nozzle portion By providing a recess with a predetermined shape on the extension of the vertical bisector, even if the filled and sealed contents are viscous, it can be refilled smoothly to the end, and , Which is formed by penetrating through a base material layer of one or more laminated materials extending from the tip side near the top of the bulging portion A of the pouring nozzle portion to the bulging portion B side and immediately before the hollow portion. A straight half-cut groove is provided to Becomes flexible portions of the cut groove, even pressure is applied from outside to the nozzle portion pouring the spout shape tends to restore to its original state, it can dispense up to the end.

  The bag-like container with a dispensing function of the present invention is made of a laminated material having at least a base material layer and a sealant layer, has a bottom seal part on one side of the container main body part, and linear side seals at both ends of the bottom seal part The bag is sealed at one end of the unsealed side of the bag-like container having the unsealed side opposite to the bottom seal part, and the one-side bulge height on the tip side is 1.0-5. A convex pouring nozzle portion having a bulging portion A of 0 mm is provided, and a bulging portion B having a predetermined shape is provided on the container main body portion connected to the pouring nozzle portion, and within the region of the bulging portion B, A depression having a predetermined shape is provided on an extension of the perpendicular bisector in the width direction of the dispensing nozzle, and the depression is formed from the tip side near the top of the bulging part A of the dispensing nozzle toward the bulging part B. One or more linear half-cut grooves extending just before the part are provided, Since the straight half-cut groove is formed by cutting through the base material layer of the laminated material, when refilling the filled contents into other bottles, etc., the dispensing flow path of the dispensing nozzle section It is hard to block, and the contents can be poured out stably.

  The bag-like container with the dispensing function of the present invention will be described below along the embodiment. Fig.3 (a) is a sectional side view which shows one Embodiment of the laminated material used for the bag-shaped container with the extraction | pouring function of this invention, and a laminated material (20) is a base material layer (21) in order in a thickness direction.
