Since the notch is provided at the lower edge of the side plate of the paper box, the paper box can be easily removed from the paper container containing the liquid material such as the alcoholic beverage at the time of use. Since the top surface of the paper box is constituted by the top plate connected from the upper end of one side plate via a bending line, the paper box can be transported and stored in a folded state, and the space is not taken more than necessary.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments. As shown in FIGS. 1 and 2, the liquid material package of the present invention includes a gable roof paper container 10 filled with a certain amount, for example, 180 ml of sake (not shown), and a top portion 11 of the paper container 10. A paper box 20 having a flat top surface, four side plates 21, 22, 23, 24 and an open bottom portion, and having the same height as the paper container.
And a heat-shrinkable transparent plastic film 30 covering the entire gable roof paper container 10 covered with the paper box 20.

A gable-roof paper container 10 filled with a certain amount of sake is formed by folding a gable-roof-shaped top portion 11, a square body portion 12, and a lower portion of the body portion at the lower end of the body portion. The top portion 11 is provided with a spout 14 for pouring sake as needed. The cross section of the paper container is not limited to a square as shown in the figure, but may be a rectangle. In addition, a printed layer such as a character and a picture is provided on the outer surface as needed.

The paper container is manufactured by processing a laminated sheet composed of a cardboard as a base material and having an inner layer and an outer layer made of a heat-sealable thermoplastic synthetic resin into a paper container sleeve, and then producing the sleeve. The material of the laminated sheet may be any material that can hold a liquid material such as an alcoholic beverage and can withstand long-term storage.
Known materials such as paperboard / polyethylene / aluminum foil / polyethylene terephthalate film / polyethylene [outside the container] can be preferably used.

Further, the operation of producing the paper container from the paper container sleeve and the operation of filling sake into the paper container can be easily performed by a generally used paper container filling machine. Also,
If necessary, a spout for pouring sake can be attached to the paper container.

The paper box 20 placed on the paper container 10 is
The top surface of a rectangular hexahedron having almost the same height as 0 is open, except that the top surface is open and foldable and easy to assemble. The top surface is robust and slightly larger than the paper container that can be completely covered on the paper container 10. For example, a structure as shown in FIGS.

FIG. 4 is an exploded view of the paper box blank, in which the first side plate 21, the second side plate 22, the third side plate 23, the fourth side plate 24, and the adhesive margin 25 are connected via bending lines. Has been established.

A tongue piece 211 is continuously provided at an upper portion of the first side plate 21 via a bending line, and a notch 212 is provided at a lower end of the first side plate 21 so that a finger can be inserted.

A top plate 221 and insertion pieces 222 to be inserted into the fourth side plate 24 are sequentially provided on the upper portion of the second side plate 22 via bending lines.

A tongue piece 231 is connected to the upper portion of the third side plate 23 via a bending line, and a notch 232 is provided at the lower end of the third side plate 23 so that a finger can be inserted.

The cutouts provided at the lower ends of the first side plate 21 and the third side plate 23 are provided not in the first side plate 21 and the third side plate 23 but in the second side plate 22 and the fourth side plate 24. Alternatively, it may be provided on all side plates. If one of the four side plates is open instead of the bottom plate, a notch may be provided at the open end of the opposing side plate.

The production and assembly of the paper box are performed, for example, as follows. First, while bending each side plate and the adhesive margin along a folding line provided in the height direction of the blank, for example, a generally known adhesive such as a vinyl acetate emulsion adhesive is applied to the adhesive margin. 25, the fourth side plate 24 and the first side plate 21 are folded, and the adhesive margin piece 25 and the back surface of the first side plate 21 are pressed to form a sleeve, thereby completing the production of the paper box. This operation can be easily performed by a generally known paper box making machine.

The sleeve-shaped paper box is raised, and the tongue pieces 211 and 231 are folded inward.
1 is folded inward, and the insertion piece 222 is
14, the assembly of the paper box 20 is completed.

The paperboard used for the paper box can be a coated ball, a coated manila, or the like, and the surface thereof is provided with a printed layer on which necessary characters and pictures are printed.

The plastic film 30 covers the entire surface of the paper box 20. The paper box 20 covered with the paper container 10 is wrapped in a transparent plastic film, and is sealed by fusing and sealing with, for example, a three-way sealing machine. When the plastic film 30 is passed through the shrink tunnel, the plastic film 30 contracts due to heat and adheres tightly to the object to be packaged, thereby completing the shrine packaging 1 that is a tight liquid material package. In this embodiment, a transparent plastic film is used. However, the plastic film is not limited to a transparent film, and may be translucent or colored.

As the heat-shrinkable plastic film 30, a shrink film of polypropylene, polyethylene, vinyl chloride or the like is used. For example, 30μ
m polyethylene shrink film can be preferably used.

[0026]

As described above, the paper-based package of the present invention can be disposed of without inconvenience in disposal, unlike glass bottles returned to shrines, etc., and can be disposed of easily. It is. In addition to the sacred sake, it can also be used for sake, funeral ceremonies, or celebrations. In addition to containing alcoholic beverages and utilizing them as sacred sake packagings, the liquid material package further includes refreshing drinks such as coffee and juice, seasonings such as soy sauce, sauces, cooking oils, or liquid detergents, motor oils, etc. Can be applied to various fields as a package for various liquids. Furthermore, there is no danger of being damaged when carrying, unlike glass or ceramics. If printing is performed on the outside of the paper box, printing on the outside of the paper container does not need to be performed, so that a small lot can be handled in a short time. Also, since each process of paper container filling box making process, paper box covering process, fusing sealing process, heat shrinking process is processed in this order,
The liquid package of the present invention can be easily produced.
