DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a packaging box having a partition according to the present invention will be described below with reference to the drawings. 1 is a perspective view showing an example of the packaging box 1 of the present invention.

In the packaging box 1 having a partition according to the present invention, as shown in the figure, a box body 2 and a partition 3 are integrally provided inside the body 2, and the partition 3 is as shown in the figure. It is not limited to the form, and various forms according to the shape of the product to be stored can be appropriately adopted.

An example of the packaging box 1 of the present invention shown is a packaging box used for storing soap (see FIG. 2),
The partition 3 provided in the packaging box 1 is also in a form suitable for storing soap, but the packaging box 1 of the present invention is not limited to those used for such an application. It can be configured to be able to store canned water yokan, rice cracker, confectionery such as sponge cake, coffee bean set, tea bag set, etc. In this case, the form of the partition 3 is as described above. In addition, it may be appropriately selected according to the shapes of the above various products.

Further, the packaging box 1 of the present invention has a mode as shown in FIG. 1 which comprises only a storage section 4 in which a box partition 2 is integrally provided with a box body 2, and a separately formed lid is put on this. Alternatively, the opening may be covered with a transparent film or the like, or may be integrally formed so that the lid 5 is connected to the storage portion 4 as shown in FIG. good.

Further, the packaging box 1 having the partition according to the present invention as described above, the papermaking component in the papermaking raw material liquid is made into a papermaking mold, and the papermaking component is dehydrated (papermaking molding step), and then the papermaking mold. FIG. 3 shows a papermaking molding in which the above-mentioned papermaking molding step is carried out. An outline of an example of the mechanism 14 is shown, and FIG. 4 shows an outline of an example of the dry molding mechanism 15 in which the dry molding step is performed. The partition 3 is not shown in FIGS. 3 and 4.

In the paper making process, for example, as shown in FIG. 3, an upper mold 6 having an inner surface shape or an outer surface shape of the packaging box 1 is formed.
(In the example shown, it is formed in a shape that substantially matches the outer surface shape of the packaging box 1), the papermaking mold 7 having the outer surface shape or the inner surface shape of the packaging box 1 (in the example shown, the inner surface shape of the packaging box 1) And a support frame 8 (9 in the drawing is a hole for drainage) for supporting the papermaking mold 7, and the upper mold 6 and the papermaking mold 7 are molded. It is preferable that the papermaking and molding mechanism 14 forms a papermaking and molding space between the two when they are combined.

Although not particularly shown, the papermaking mold 7 is provided with a plurality of through small holes on the wall surface or the upper surface thereof, and the through small holes are for allowing moisture in the papermaking raw material liquid to permeate. However, in order to allow water to efficiently permeate and not allow papermaking components to permeate, it is usually preferable that the holes have a diameter of 0.5 mm to 2.0 mm. If the pores are too large, the amount of papermaking components passing through the pores will be increased, which will hinder the papermaking molding of the location, or the papermaking components will enter into the pores, and the resulting packaging box 1
There is a risk that the traces of holes will remain clearly on the surface, which will deteriorate the appearance. On the other hand, if the holes are too fine, clogging easily occurs.

On the other hand, the upper mold 3 is provided with a large number of fine holes through which air and water vapor can pass, and the material is preferably a metal or an elastic material. Examples of the metal include aluminum and nickel. Examples of the elastic material include rubber, elastic synthetic resin, synthetic resin foam and the like.

In the papermaking molding process performed by the papermaking molding mechanism 14 configured as described above, for example, a papermaking molding raw material liquid is poured onto the papermaking mold 7 and the papermaking components in the papermaking molding raw material liquid are added to the papermaking mold. 7 or by immersing the entire papermaking mold 7 in the papermaking raw material liquid tank in which the papermaking raw material liquid is stored, and if necessary vacuum suction from below the die 7 before making the papermaking die 7 Is increased to remove the papermaking components onto the papermaking mold 7 and the like, and the papermaking components onto the papermaking mold 7 as they are,
Next, the papermaking mold 7 and the upper mold 6 are matched with each other to press the papermaking components that have been removed, and, if necessary, vacuum suction from the lower surface side of the papermaking mold 7 and / or the upper surface side of the upper mold 6. The water in the papermaking component is dehydrated by pressurizing with air.
As a result, most of the water remaining in the papermaking components drawn on the papermaking mold 7 flows out of the support frame 8 through the through-holes of the papermaking mold 7, and the water is left on the papermaking mold 7. The papermaking components contained to some extent remain, and a molding intermediate 10 having a shape that fills the papermaking molding space is formed.

When the papermaking components are drawn into the papermaking mold 7 as described above, the amount of the papermaking components to be drawn on the papermaking mold 7 depends on the concentration of the papermaking components dispersed in the papermaking molding raw material and the papermaking component. It can be adjusted by the vacuum suction time and the like, which are performed as needed when the paper is taken out into the mold 7. Further, as the papermaking molding raw material liquid, a conventionally known pulp raw material liquid or a material obtained by adding a pigment or various other additives thereto can be used, but the papermaking molding raw material liquid uses recovered paper. It does not matter if the recycled pulp raw material occupies all the components or only a part thereof.

Thus, the papermaking components in the papermaking raw material liquid are taken out onto the papermaking mold 7, pressed by the upper mold 6 from the upper surface side, and further, if necessary, the lower surface side of the papermaking mold 7 is depressurized. When the water content is dehydrated, the molded intermediate product 10 thus obtained has a water content of about 30% by weight to 70% by weight, and the pressing by the upper mold 6 causes the papermaking components to be removed onto the papermaking mold 7. When the apparent thickness is 100, it is preferable that the thickness is about 10 to 40. If the lower surface side of the papermaking mold 7 is decompressed, the decompression condition is 700 mmHg.
It is preferably about 10 mmHg.

Next, the molded intermediate product 10 obtained as described above is transferred to a dry molding step to perform dry molding.
In the dry molding step, for example, as shown in FIG. 4, an upper press die 12 having an inner surface shape or an outer surface shape of the packaging box 1 (in the example shown in the drawing, is formed into a shape that substantially matches the outer surface shape of the molded product. .) And a lower press die 13 having an outer surface shape or an inner surface shape of the packaging box 1 (in the example shown in the figure, it is formed in a shape substantially matching the inner surface shape of the molded product). It is preferable that a dry-molding mechanism 15 composed of a pair of male and female press dies, which forms a dry-molding space between the mold 12 and the lower mold 13, is preferably formed.

Further, the dry-molding mechanism 15 needs to be provided with a means for drying the molding intermediate product 10. As the drying means, the dry-molding mechanism 15 is provided with an electric heating device to form the molding intermediate product during dry molding. 10 may be heated and dried, or a high frequency oscillator may be connected to the press die 7 and a high frequency may be applied to the molding intermediate product 10 at the time of dry molding by the high frequency oscillator to dry it. Can also be used in combination.

In such a dry molding mechanism 15, the intermediate molding product 10 is sandwiched in the dry molding space formed between the upper press die 12 and the lower press die 13, and the upper press die 12 and the lower press die 13 are sandwiched. The molded intermediate product 10 is dried and finally molded by applying pressure to the molded intermediate product 10 by clamping and heating (or applying high frequency). Box 1 is obtained.

In the dry molding process as described above, the pressing force applied to the molding intermediate product 10 is 1 kg / cm.
²・ G-10kg / cm ²・ G, press time is 3 seconds-100
It is preferable that the time is about 2 seconds, and the thickness of the final product is the papermaking mold 7.
It is preferable to perform dry molding so that the apparent thickness in the state where the papermaking components are removed from the above is about 5 to 30, and in the case of heat drying, the heating temperature is 50 ° C.
It is up to 400 ° C., and when drying is performed by applying a high frequency, 10 ³ Hz to 10 ¹³ Hz, preferably 10 ⁶ Hz
-10 ¹² Hz, more preferably 10 ⁷ Hz-10 ⁸ Hz
A high frequency with an oscillation frequency of 1 kw to 100 kw is applied.

The thickness and density of the packaging box 1 of the present invention obtained in this manner are determined by the shape and weight of the products to be stored in the packaging box 1, and further the required strength, lightness, cost and the like. The thickness and the density can be appropriately selected in consideration of the amount of the papermaking component to be made in the papermaking mold 2 and the degree of pressurizing the papermaking component to be made, as described above. Although it can be adjusted, it is generally preferable that the wall thickness is about 1.5 to 2.5 mm and the density is about 0.0172 to 0.0694 g / cm ³ .

Further, in each of the papermaking molding process and the dry molding process, the side surface of the packaging box 1 of the present invention is not formed vertically so that the molded product can be easily separated from the mold, and the side of the opening portion is not formed vertically. It is preferable that the packaging box 1 is formed so as to spread a little in the inside of the packaging box 1. When formed in this way, the packaging box 1 located above when the plurality of empty packaging boxes 1 are stacked is placed inside the packaging box 1 located below. Since it will fit in more or less, it is less bulky during storage than conventional packaging boxes. In addition, the packaging box 1 of the present invention is not limited to one that stores a plurality of products, but may be one that stores only one product in some cases.
