Description

  The present invention relates to a packaging bag mainly filled with a liquid content, and particularly to a packaging bag to which a dispenser for discharging the liquid content is attached.

  Conventionally, liquid contents such as liquid detergents, body soaps, shampoos, rinses and the like are made of molded products made of the same thermoplastic resin to which a push-type dispenser made of a molded product made of a thermoplastic resin is attached in order to obtain a predetermined amount of use. Bottled containers have been filled and provided. In recent years, in order to reduce waste and reduce volume due to environmental problems, refill the liquid contents from a refillable packaging bag or a thin molded bottle, and reuse the bottle-shaped container. In general, packaging bags and thin molded bottles are folded or compressed, reduced in volume, and discarded.

However, in the method of refilling from the refill packaging bag or thin molded bottle and reusing the bottle-like container, the packaging bag or thin molded bottle only for refill needs to have material specifications corresponding to the contents. In addition, the operation of the push-type dispenser requires a bottle-shaped container that can withstand the pressing operation, and the manufacturing cost generated from the equipment for manufacturing the bottle-shaped container and the resin material is high. In the case of disposal due to deterioration or fouling of a container or box-shaped container, the disadvantage that the volume of waste cannot be reduced by any means cannot be solved. On the other hand, a bag with a pump in which a push type dispenser is directly attached to the bag used for refilling has been proposed (see, for example, Patent Document 1).
JP 2002-347867 A

The bag with a pump of the structure seen in the said patent document 1 has a pump in the bag upper part, provided the support part which hangs a finger on this pump, and supports a support part with a finger in the case of pump operation, A pushing part By pressing the pump, the contents are discharged and the conventional bottle-like container or box-like container is not required.Therefore, refilling work is unnecessary, and it is not bulky, so the effect is good. It is what you have.
However, during the discharge operation as described above, it is necessary to perform the pressing operation of the pump while supporting the bag with the finger, and it is possible to operate the pump in a state where it is placed like a conventional bottle-shaped container or a box-shaped container. In comparison, it is difficult to operate and there is a need to master it. In addition, as the liquid content decreases, the bag body deforms due to the reduced pressure inside the bag, the pump suction port is blocked, and the content cannot be sucked in and cannot be discharged, and it is not able to maintain its independence and buckles. It had drawbacks such as easy falling.

  Accordingly, an object of the present invention is to solve the above-mentioned problem, and the operation of the push-type dispenser can be easily performed in the same manner as a conventional bottle-shaped container, and the liquid content is used at the time of use. The deformation of the packaging bag due to the internal pressure reduction accompanying the decrease in the liquid content remains at a certain level, the liquid contents can be discharged without the dispenser suction port being blocked, and the packaging bag body maintains its independence, An object of the present invention is to provide a packaging bag with a dispenser that obtains a reaction force against a pressing operation and does not cause a fall due to buckling.

In order to solve the above-mentioned problem, the invention of claim 1 is a packaging bag in which a spout body to which a push-type dispenser can be attached is fixed to an upper end, and the spout body is self-supporting inside the packaging bag. The leg structure of the spout body is formed from the opposite sides of the lower end periphery of the canopy portion having a spout portion and having a joint base at the periphery. It is a parallel plate-like shape, and is characterized in that at least one or more through-hole portions are formed in each plate-like surface and at least one or more notch portions are formed only in the lower end of each plate-like surface. It is a packaging bag with a dispenser.

The invention of claim 2 is a packaging bag in which a spout body to which a push-type dispenser can be attached is fixed to an upper end, wherein the spout body is capable of self-supporting inside the packaging bag. A polygonal cylindrical or cylindrical shape in which the leg structure of the spout body is continuously provided from the outer periphery of the lower end periphery of the canopy portion having a spout portion and having a joint base at the periphery. is Jo, are characteristic and to Lud I Spencer packaging bag with that at least one or more through holes portion to the cylindrical side surface, bored and at least one or more notch only the lower end of the cylindrical side .

The invention according to claim 3 is the packaging bag with a dispenser according to claim 1 or 2, wherein the packaging bag is a self-supporting bag having a gusset portion at the bottom and heat-sealing both side edges. It is.

According to a fourth aspect of the present invention, the packaging bag is a gusseted bag having a gusset portion that folds the left and right sides inward in a crease shape and heat-sealing the lower end edge with a bottom seal portion. Or it is a packaging bag with a dispenser of Claim 2 .

  In the packaging bag with a dispenser of the present invention, a leg structure that can stand on its own is continuously provided from a spout body fixed to the upper end of the packaging bag. Even if the pressing operation is performed, the packaging bag is not crushed by the reaction force of the leg structure. This effect eliminates the need for a thick bottle-shaped container formed by plastic molding, which has been conventionally required, and enables cost reduction of equipment for manufacturing the main body and resin material. In addition, there is an effect that volume reduction which is difficult when the bottle-shaped container is discarded can be easily performed in the packaging bag with a dispenser of the present invention.

  The operation of the push-type dispenser can be performed by placing it in a predetermined place as in the case of the conventional bottle-shaped container, so that the bag is supported by a finger like the bag with a pump shown in the above-mentioned patent document. There is no need to perform a special operation such as pressing the pump, and the operation can be performed easily.

  When in use, the liquid contents are discharged by the pressing operation of the push-type dispenser, and the inside of the packaging bag is depressurized and deforms. However, the leg structure or polygon that is connected to the spout body of the present invention is deformed. Cylindrical, cylindrical, or plate-like leg structures parallel to each other maintain the space inside the packaging bag and the space inside the leg structure or between the leg structures, and the packaging bag is deformed to a certain extent. Therefore, the liquid content can be discharged without blocking the dispenser suction port.

  In the packaging bag with a dispenser of the present invention, the packaging bag is a self-supporting bag having a gusset part at the bottom and heat-sealing both side edges, and the buckling of the packaging bag is eliminated by the self-supporting nature of the leg structure. Thus, there is an effect that the fall of the packaging bag hardly occurs even when the liquid content is reduced. In addition, when the packaging bag is a gusseted bag that has a gusseted portion that is folded inward on both the left and right sides and has a lower end edge that is heat-sealed with a bottom seal portion, the leg structure is formed of the packaging bag. Since the deformation is held at a certain level and the gusset widths on both the left and right sides are maintained, there is an effect that the packaging bag does not easily fall over.
