Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box which is used for packaging of goods for transportation and which can be displayed in a large quantity by stacking the goods in a state of being partially exposed at a store and being exposed. The present invention relates to a packaging box suitable for displaying a flexible and easily deformable product.

2. Description of the Related Art Conventionally, as a packaging box of this type, those described in Japanese Utility Model Laid-Open No. 7-31620 and Japanese Patent Laid-Open No. 11-292064 are known.

The packaging box disclosed in Japanese Utility Model Laid-Open No. 7-31620 makes it possible to open a part of the upper center of the front wall of the front, rear, left, and right walls surrounding the four sides, and configure the upper lid wall. The central part is configured to be opened further.
The products housed inside can be displayed in two types of states, a first open state in which only the front wall surface is open and a second open state in which both the front wall surface and the upper lid wall are open.

The packaging box described in Japanese Patent Application Laid-Open No. 11-292064 is such that among the front, rear, left, and right wall surfaces that surround the four sides, a part of the upper center of the front wall surface can be opened, and all the front, rear, left, and right wall surfaces are opened. The upper part can be opened further. The products housed inside can be displayed in two types of states, a first opened state in which only the front wall surface is opened and a second opened state in which all upper portions in the front, rear, left, and right are opened.

[0005]

However, the former packaging box is disadvantageous in that it cannot lead to sales promotion because the product cannot be seen unless the consumer stands on the front side.

In the latter packaging box, the upper portions of all the front, rear, left and right wall surfaces can be opened to form a tray state.
Consumers can see products from any position, which leads to sales promotion. However, when a liquid is stored in a resin bag material and a product that can be placed in an upright state (a so-called standing pouch) is stored, the product is flexible and easily deformed, so the product can drop with a small impact. There is a nature.

[0007] Therefore, it is an object of the present invention to provide a packaging box which is suitable for displaying flexible and easily deformable products and which is also connected to sales promotion.

[0008]

In order to solve the above-mentioned problems, the packaging box of the present invention comprises a peripheral wall surrounding four sides and a lid wall closing at least the lower opening of the peripheral wall. Of the front, rear, left, and right wall surfaces that constitute the rectangular packaging box, the front and rear wall surfaces extend in the lateral direction, and in the peripheral wall, at least the front of the partition wall extending between the front and rear wall surfaces and the front and rear wall surfaces and the left and right wall surfaces. A separation band that extends laterally across the wall surface and the left and right wall surfaces adjacent to the front wall surface, and that can break the front left and right wall surfaces in the lateral direction, and a pair of first first members that extends upward from the separation band on the front wall surface. Cutting means and second cutting means extending between the upper ends of these first cutting means, and a third cutting piece that extends upward from the separation band on the left and right wall surfaces and has its end located on the rear wall surface. And means provided in said front wall, a pair of first cutting means, second cutting means and,
A part surrounded by the separation band between the first cutting means can be opened, and the separation band on the front wall surface is formed by the third cutting means and the separation bands between the third cutting means on both sides. And the left and right wall surfaces are partially openable.

Here, the cutting means includes a cutting line that extends linearly at a predetermined interval and a so-called single zipper that extends obliquely from one end of the cutting line, a zipper in which a pair of these zipper is symmetrically provided, or a separation line. Like the strip, it consists of a strip that can break the wall surface. Further, in the first cutting means and the third cutting means provided on the front wall surface and the left and right wall surfaces, "from the severance zone" means that the severing zone is a starting point and the severing zone is cut. Means a state. Furthermore, the upper part of the severance zone means the state above the lower edge of the severance zone and the severance zone is also separated.

According to the packaging box, for example, by pulling the separation band, the first cutting means on the front wall surface is broken laterally. Thereafter, the first cutting means and the second
The portion surrounded by these is cut along the cutting means.
As a result, the first open state in which a part of the front wall surface is open can be achieved.

In the first opened state, the separation band is pulled so that the remaining portion of the front wall surface located between the third cutting means and the first cutting means and a part of the left and right wall surfaces are laterally moved. To break. Alternatively, in a state in which the upper and lower sides of the packaging box are closed, a part of the front wall surface and the left and right wall surfaces is provided by the cutting band between the first cutting means and the cutting band between the third cutting means and the first cutting means. Break. After that, by cutting the left and right wall surfaces along the third cutting means, the upper part of the separation band on the front wall surface and a part of the left and right wall surfaces are cut. As a result, in the upper part of the separation zone, the front wall surface and the left and right wall surfaces can be partially opened to the second open state.

As described above, in the packaging box of the present invention, the products housed inside can be displayed in two kinds of states. In the second open state, most of the upper part of the severing zone can be separated except for the rear wall surface and the left and right wall surfaces continuous with the rear wall surface. Therefore, the number of consumers is 3
People can see the product and get a sales promotion effect. Moreover, since the rear wall surface and the partition wall remain in the second open state, even if the product to be stored is flexible and easily deformed, the stable mounting state can be maintained and a small impact is applied. This can prevent the product from falling.

In the packaging box, the peripheral wall, the lid wall and the partition wall are made of one continuous punched product. The left and right wall surfaces are continuous with both sides of the front wall surface forming the peripheral wall. A rear wall constituting surface forming a rear wall surface is continuous with the wall surface, and the front wall surface, the left and right wall surfaces, and a flap forming the lid wall are continuous with lower edges of the rear wall forming surface, and one rear wall surface is formed. It is preferable that the partition wall is continuous with the wall-constituting surface, the end portion of the rear wall-constituting surface is overlapped and fixed, and the end portion of the partition wall is fixed to the inner surface of the front wall surface. By doing so, it is possible to reduce the number of parts, which is suitable in various aspects such as workability in manufacturing, product management in storage, and storage space, and it is possible to significantly reduce the cost. .

In this case, flaps constituting a lid wall for closing the upper opening of the peripheral wall are further provided at the upper edges of the front wall surface, the left and right wall surfaces, and the rear wall constituting surface, and the rear wall constituting surface and the upper lid are provided. It is preferable to provide the fourth cutting means at the boundary with the flap forming the wall. In this way, the upper part of the severing zone can be surely separated from the rear wall surface and the left and right wall surfaces.

Further, it is preferable that the partition wall is constructed so as to extend over the upper and lower lid walls. In this way, since the partition wall serves as a reinforcing member, by stacking a plurality of packaging boxes, even if a vertical compression force is applied to the lower packaging box, the entire packaging box is deformed. It can be prevented.

[0016] It is preferable that the separating band is arranged so as to extend over all the wall surfaces constituting the peripheral wall so that the upper part of the separating band can be opened entirely. If you do this,
Since three kinds of display states can be secured, the sales promotion effect can be further obtained, and it can be applied to both flexible products that are easily deformed and stable products that are not deformed.

As is apparent from the above description, the packaging box of the present invention can display the products contained therein in two kinds of states. Particularly, in the second open state, most of the upper part of the severing zone can be separated except for the rear wall surface and a part of the left and right wall surfaces continuous with the rear wall surface. Therefore, the consumer can see the product from three sides, and the sales promotion effect can be obtained. Moreover, in the second open state, the rear wall surface and the partition wall remain, so that even if the product to be stored is flexible and easily deformed, a stable mounting state can be maintained and a shock is applied. It is possible to prevent products from falling easily.

Further, since the partition wall is constructed to extend to the upper and lower lid walls, it can serve as a reinforcing member. Therefore, even if a plurality of packaging boxes are stacked, a load is applied to the lower packaging box and the entire packaging box can be prevented from being deformed.
