Description

  The present invention comprises a package body filled with a liquid or viscous material in an inner bag provided with a narrow-width spout portion protruding upward, and an outer bag containing the package body. The present invention relates to a package that can easily dispense the contents filled in the inner bag by applying an external pressure by squeeze.

Conventionally, the contents of viscous bodies such as mayonnaise have been stored and sold in squeeze plastic containers. In addition, as a package containing such viscous contents such as mayonnaise, in a double container in which the inner container containing the contents is accommodated in the outer container, the inner mayonnaise etc. The outside air is introduced between the outer container and the inner container by the vent hole provided at the bottom of the outer container, the inner container keeps the deformed shape, and the outer container A blow-molded double container that is restored to its original shape by the restoring force is known (for example, see Patent Document 1).
However, the container described in Patent Document 1 has a drawback in that an outer container and an inner container are produced and a process of assembling them is required, which increases the cost of the container. Moreover, as a solution to these disadvantages, the outer shell layer that forms the external container having reversible flexibility and the contents of the liquid and the viscous body are accommodated in the inside, and the internal pressure is reduced inward. There is known a blow-molded dispensing container in which an inner layer that forms an internal container that can be deformed and deformed is detachably laminated (see, for example, Patent Document 2). Since the containers described in Patent Documents 1 and 2 are all formed by blow molding, injection molding, or the like, the cost of transporting the empty container to the place where the contents are filled into the container is high because the empty container is bulky. In addition, the user has a problem that the container becomes bulky and waste (waste) increases after use.

  In addition, in a liquid dispensing container having a structure in which the inner lid provided with the dispenser, the container, and the cut is separable, after removing the heat seal part of the refillable packaging bag filled with the contents, Set the packing bag for refilling into the notch, put it in the container, use the handle hole provided at the top of the packaging bag, hold the inner lid by hand, pull the packaging bag up, An easy-to-refill liquid dispensing container in which the weakly bonded portion is broken and the contents are squeezed out into the container is also disclosed (see, for example, Patent Document 3). Since the liquid dispensing container of Patent Document 3 is a refilling method, it is only necessary to transport the packaging bag to the place where the contents are filled, and it is not bulky, so the transportation cost can be reduced, and it is also bulky for the user after use. Since there is no such thing, it led to volume reduction of garbage. However, every time the contents are used up, the refill packaging bag must be set in the liquid dispensing container, and it is necessary to repeat the above troublesome setting procedure, which is troublesome for the user (consumer). is there.

2 is a cross-sectional view taken along the line CC of FIG. 1 and is an enlarged cross-sectional view of the spout portion.
As shown in FIG. 2, on the inner side of the spout portion 37, a pouring auxiliary member 371 is bonded to the inner surface of the inner bag laminate 30 by thermal bonding or the like.
The extraction assisting member 371 is made of a member having an open portion 371c in the longitudinal direction and having elasticity that is entirely hook-shaped (substantially C-shaped in cross section). Further, the pouring auxiliary member 371 is attached to the inner surface of the inner bag laminate 30 from the portion facing the opening portion 371c. At that time, the inner bag laminate 30 is attached to the opening portion 371c of the pouring auxiliary member 371. The pulling force works toward you. Since the dispensing auxiliary member 371 has the opening portion 371c and has elasticity, the dispensing auxiliary member 371 is elastically deformed and becomes smaller than the outer diameter in the state before being attached. Since the applied tensile force and external force can be reduced, damage to the inner bag laminate 30 and generation of wrinkles can be prevented. In the case where the dispensing auxiliary member 371 does not have an open portion 371c such as a cylindrical body, the outer diameter cannot be reduced even if elastically deformed (the outer circumference cannot be shortened), and the inner The tensile force and external force applied to the bag laminate 30 cannot be reduced. Moreover, since the pouring auxiliary member 371 is attached so that the outer diameter becomes smaller than the state before being attached, an outward force always acts, and the opening property and the shape retaining property of the pouring route of the contents at the pouring port are improved. It can be stably maintained over time, and the contents can be poured out. The central hollow portion including the open portion 371c of the extraction auxiliary member 371 serves as a fluid flow path for extracting the contents. And as this pouring auxiliary member 371 is disclosed in JP 2012-101855 A, in the manufacturing process, a long winding shape is produced along these rollers between the rollers. It is pulled and conveyed, cut to a required length on this roller, and attached to the spout 37 of the inner bag 3 by heat sealing.

  The dispensing auxiliary member 371 is made of a material that can be heat-sealed with the heat-adhesive resin layer of the inner bag laminate 30 and can be made of, for example, medium density polyethylene, low density polyethylene, or polypropylene. From the viewpoint of moldability, it is preferable that the material of the extraction assisting member 371 is the same as that of the heat-adhesive resin layer of the inner bag laminate 30.

  Further, the dispensing auxiliary member 371 preferably has a two-layer structure including at least an inner layer portion 371a and an outer layer portion 371b as shown in FIG. 2. In this case, the material constituting the outer layer portion 371b is made of, for example, a density. A low density polyethylene having a melting point of approximately 0.915 and a melting point of approximately 100 ° C. is used, and a material constituting the inner layer portion 371a is, for example, a high density polyethylene having a density of approximately 0.930 and a melting point of approximately 130 ° C. By adopting such a configuration, the material of the inner layer portion 371a has a higher melting point than the material of the outer layer portion 371b, so that the dispensing auxiliary member 371 is heat-sealed on the inner surface of the heat-adhesive resin layer of the inner bag laminate 30. In this case, the inner layer portion 371a is not easily melted, so that the spout portion 37 is less likely to be blocked, and the opening property and shape retention of the spout port can be improved.

Next, a method for producing and using the package 1 of the present invention will be described. First, the inner bag 3 is filled with the contents 4 to produce the package 2.
As shown in FIG. 1, the spout portion 37 of the inner bag 3 is sandwiched between outer bag stacks 50 on the front and back of the outer bag 5, and the outer surface of the inner bag stack 30 of the inner bag 3 and the front and back of the outer bag 5. When the inner surface of the outer bag laminate 50 is thermally bonded by the upper end seal portion 51 of the outer bag 5, it is bonded by the bonding portion 51 a. A peripheral edge of the outer bag 5 is formed with an upper end seal part 51, an adhesive part 51a between the outer bag and the inner bag, a left end seal part 52, a right end seal part 53 having a gas sealing port 55, and a lower end seal part 54. The body 2 is enclosed in the outer bag 5, and the upper part of the spout 37 of the inner bag 3 is projected outward from the upper end of the outer bag 5.

  Next, a gas such as air, nitrogen gas or carbon dioxide gas is sealed from the gas sealing port 55 into the space 6 surrounded by the outer surface of the inner bag 3 and the inner surface of the outer bag 5 of the package 2 enclosed in the outer bag 5. After that, the gas sealing port 55 is thermally bonded and integrated with the right end seal portion 53 and sealed to produce the package 1. It is preferable that the production of the package for filling the contents into the inner bag, the assembly of the package and the outer bag, and the gas filling into the outer bag are performed on a filling machine. Of course, it is also possible to prepare in advance as a separate step only the step of producing a package for filling the contents into the inner bag. The outer bag 5 is filled with gas by inserting a gas blowing nozzle (not shown) from an unsealed gas filling port 55 into the space 6 surrounded by the outer surface of the inner bag 3 and the inner surface of the outer bag 5. Then, an appropriate amount of gas such as air, nitrogen gas or carbon dioxide gas is blown into the space portion 6, and the gas blowing nozzle is pulled out while pressing the gas filling port 55 so that the gas does not leak from the space portion 6. It heat seals and seals in the state with which the space part 6 was filled with gas.

  When using the package 1, the inner bag is cut in the left-right direction from the notch 39 along the planned opening line 38 to remove the portion including the upper end seal portion 31, and the spout (not shown) is inserted into the spout portion 37 of the inner bag 3. Not). When the outer bag 5 is squeezed by hand and an external pressure is applied, the inner bag 3 is entirely pressurized by the gas filled in the space 6 surrounded by the outer surface of the inner bag 3 and the inner surface of the outer bag 5. The contents 4 enclosed in can be squeezed out and poured out. In the case of the conventional blow container, as the contents are poured out by the squeeze deformation of the container, it is necessary to wait until the container is restored to its original shape in order to reduce the volume of the container and further facilitate squeezing. According to the package 1 of the present invention, even if the gas in the space 6 is squeezed and deformed by the contents 4 of the inner bag 3 and the volume of the inner bag 3 decreases, Since the amount of gas filled in the part 6 is constant and does not decrease, the contents 4 can be continuously poured out. Furthermore, since the space portion 6 is formed so as to cover the entire inner bag 3, the entire inner bag 3 can be pressurized, so that the residual amount of the contents 4 in the bag can be reduced. Moreover, what is necessary is just to seal the opening part of the front-end | tip which the spout part opened, after pouring a required quantity with a clip etc. When the package is discarded after use, the gas filled in the space 6 can be easily discharged by cutting the outer bag 5, and reducing the volume of the trash without bulking the package. Can be planned.
