[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shrink package in which a so-called pouch with a nozzle having a nozzle for taking out the contents is shrink-wrapped together with a backing sheet.

[0002]

2. Description of the Related Art Conventional pouches with a nozzle for taking out contents are packaged by using a standing method in which packaging material costs are high. In particular, the packaging is vertically packed in a cardboard box with the nozzle up.

[0003]

The vertical filling of the cardboard box with the nozzle upward as described above is intended to prevent the nozzle from being broken or deformed due to dropping during handling or vibration during transportation. is there. However, according to the above, the packaging material cost is high, and there is no cheap pouch flat bag with a nozzle in the current market. Therefore, according to the present invention, a nozzle for taking out the contents is attached to an inexpensive pouch flat bag, and can be stacked rationally on the outer packaging cardboard box, and there is no breakage and deformation of the nozzle due to drop during handling and vibration during transportation. Another object of the present invention is to provide a shrink package in which a pouch flat bag is not damaged.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides the following shrink package. That is, a mount is applied to a pouch flat bag with a nozzle, and these are shrink-wrapped,
The outer shape of the backing is shaped according to the shape of the pouch with a nozzle, and both sides of the backing are bent, and the height of this bending is the same as the thickness of the pouch with the contents. This is a shrink package that is formed so that an acute angle is not formed at the end.

[0005]

The present invention is a package in which a flat pouch with a nozzle is mounted on a mount having a shape conforming to the shape of the pouch and is shrink-wrapped.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments shown in the drawings will be described below.
As shown in FIG. 1, pouch flat bag 1 with nozzle 2
The shrink wrapping body 5 of the present invention is formed by mounting a backing sheet 3 according to the outer shape of the flat bag and wrapping it with a shrink film 4 from the outside. A neck portion B and a shoulder portion A are formed on the backing sheet 3 in conformity with the nozzle 2, and a bent section C is formed on both sides of the backing sheet 3 so that an acute angle is not formed at an end of the bent section C. , There is a V-shaped cut like D. The notch does not have to be V-shaped,
It may be rounded without forming an acute angle. If the acute angle is not formed, the shrink film 4 does not need to be damaged. In the mount 3 ″ shown in FIG. 6, a neck portion B and a shoulder portion A are formed, but since it is a flat plate, the pouch flat bag 1 is placed on the
Both sides of the mount 3 "warp. Therefore, in the present invention, the bent portions C are formed on both sides of the mount 3. The bent height of the bent portion C is determined by the flat pouch 1 containing the contents. Set to the same thickness as

[0007] Since the present invention is constructed as described above, the lateral movement of the pouch 1 is prevented from being wrapped around the bent portion C of the backing sheet 3, and the backing sheet 3 is reinforced by the bent portion C. Therefore, even when shrink-wrapped, both sides of the mount 3 do not warp. In addition, since the neck portion B that matches the shape of the nozzle 2 is formed on the mount 3 together with the shoulder portion A,
The breakage of the nozzle 2 is prevented by the neck B, and the shoulder of the pouch flat bag 1 is fixed to the shoulder A of the backing sheet 3 by the shrink film 4, so that the nozzle 2 is not broken or deformed. Is also prevented. Therefore, even if several shrink wrapping bodies 5 like the present invention are packed side by side in a cardboard box 6 of an outer wrapping as shown in FIG. The flat bag 1 is protected, the nozzle 2 is not broken or deformed, and the pouch flat bag 1 is prevented from being damaged. FIG. 2 shows a modification of FIG. 1 in which the position of the nozzle 2 is displaced to one side of the pouch flat bag 1, but the effect is the same as that of FIG.

FIG. 3 shows a mount 3 ′ without a neck B and a shoulder A according to the shape of the nozzle 2. Table 1 shows the results of a comparative drop test of the shrink package using the mount 3 'and the shrink package 5 of the present invention.

[0009]

From the above results, even when the shrink wrapper 5 of the present invention falls in the nozzle side direction, the shrink film 4 fixes the shoulder portion of the pouch flat bag 1 at the shoulder A, which suppresses the movement of the pouch flat bag 1. Therefore, the outer packaging cardboard box 6 shown in FIG.
It was found that the pouch 1 was prevented from breaking and deforming the nozzle 2 and from damaging the pouch flat bag 1. Since the shrink wrapping body using the mount 3 'shown in FIG. 3 does not have the neck B for fixing the nozzle portion, the pouch flat bag 1 is moved by the drop impact, and is placed on the inner side of the outer wrapping cardboard box 6 in FIG. It was found that the nozzle 2 was broken and deformed and the pouch 1 was damaged.

A mount 3 "shown in FIG. 6 has a neck portion B and a shoulder portion A formed in accordance with the shape of the nozzle 2, but has no bent portion C as in the present invention. The pouch flat bag 1 is shrink-wrapped using the flat backing material 3 ", and a comparison drop test of the pouch flat bag 1 and the shrink-wrapped body 5 of the present invention is shown in Table 2.

[0012]

From the above results, it can be seen from FIG.
Was found to break the shrink film 4 at the edge of its end. On the other hand, since the mount 3 of the present invention wraps the side of the pouch 1 at the bent portion C, the shrink film 4 was not damaged. In addition, the shape of the mount 3 of the present invention may be such that the shape of the neck B is as shown in FIGS. From the above test results, in the case of the present invention, the neck part B and the shoulder part A were formed on the backing sheet 3, the bent parts C were formed on both sides, and an acute angle was not formed at the end of the bent part C. It has been proved that the above-mentioned method greatly helps to prevent breakage and deformation of the nozzle 2 and breakage of the pouch 1.

In any case, according to the present invention, a flat pouch provided with a nozzle for taking out the contents is shrink-wrapped together with a mount having a bent portion and a neck and a shoulder, thereby forming an outer packaging cardboard box. When packing several boxes, the packages can be rationally stacked in multiple stages, preventing the nozzle from being broken or deformed due to drop during handling, vibration during transportation, and prevention of pinholes in pouch flat bags. Also, the pouch flat bag can be prevented from being damaged, and can be used in the field of food and pharmaceutical packaging, which is highly effective. However, since the pouch flat bag can be protected by shrink wrapping by simply forming the bent portion and the neck and shoulders on the backing, it is extremely inexpensive compared to the case where the backing is formed in the same shape as the pouch flat bag by plastic molding. can get.

[0015]

[Effect of the Invention] According to the present invention, a nozzle for taking out the contents is attached to an inexpensive pouch flat bag, and the outer packaging cardboard box can be rationally stacked in a multi-stage manner.
Breakage and deformation of the nozzle and breakage of the pouch flat bag caused by vibration during transportation can be prevented.
