Description

[Detailed description of the invention] [Industrial application field] This invention relates to a double paper box in which a plurality of inner boxes are housed within an outer box consisting of a body and a lid.

[Conventional technology]

As shown in FIG. 7, the container for packaging elongated prismatic castella cakes, western cans, etc. is made up of a flat rectangular parallelepiped-shaped body 31 with an open upper surface, and a rectangular parallelepiped-shaped lid 32 with an open lower surface that is placed over the body 31. The outer box body 31 has openings at both ends, which are folded into the flap 3.
There was a double-layered paper box in which a plurality of separate inner boxes 36 in the shape of long and narrow rectangular cylinders, which are closed by a lid flap 35 having a locking piece 3 and an insertion locking piece 34, are housed side by side.

[Problem that the invention attempts to solve]

However, this double-walled paper box had the disadvantage that the bottom, side panels, etc. of the body and the separate inner box were doubled, requiring a large amount of paper material to manufacture, resulting in high costs.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention consists of a body member in which inner boxes are connected to the left and right ends of the bottom wall, a lid to cover this body member, and a pair of ends of the body member. It consists of a separate inner box that fits between the inner boxes of
The body member has a plurality of inner box lid flaps arranged in a row along the front and rear edges of the bottom wall, and an outer plate, a top plate, an inner plate, and a glue area that form the end inner box on the left and right edges. The separate inner box has side plates connected to the left and right edges of the bottom plate, and is bent from a base plate with folding flaps connected to the front and rear edges of the outer and inner plates. It is made by bending a base plate with a top plate and a gluing margin successively connected to the edges of the side plates, and folding flaps successively connected to the front and rear edges of the side plates.

[Effect]

With this idea, by bending a single board for the body member and gluing the adhesive to a predetermined surface, the inner box at the opposite end is connected to the bottom wall, and the lid flap for the inner box is attached to the bottom wall. The separate inner box that fits between the inner boxes at the ends is open at the front and back ends, and there is no wasted space as a whole. There is no possibility that it will be locked to the wall, that is, the body member and shake.

〔Example〕

An embodiment of this invention will be described based on the accompanying drawings. As shown in FIGS. 1 to 3, the double-walled paper box of this invention has a body member in which rectangular cylindrical inner boxes 2 are connected to the left and right ends of a rectangular bottom wall 1 of a required size. 3
It consists of a rectangular parallelepiped-shaped lid 4 with an open lower surface that is placed over the body member 3, and a separate rectangular cylindrical inner box 5 that is fitted between the inner boxes 2 at the ends of the body member 3.

The body member 3 is made by using the expandable substrate A shown in FIG. 4 and bonding it onto the bottom wall 1 at the bending margin 12 (see FIG. 2). This board A is
A plurality of inner box lid flaps 7 are arranged in a line along the front and rear edges of the bottom wall 1 via horizontal fold lines 6, and end inner boxes 2 are formed at the left and right edges via vertical fold lines 8. Elongated rectangular outer plate 9 and top plate 1 for
0, the inner side plate 11 and the glue allowance 12 are extended and connected in sequence, and folding flaps 13 are connected to the front and rear edges of the outer side plate 9 and the inside side plate 11 via the transverse fold line 6, and each lid flap 7 Insert the locking piece 1 into the tip edge of
4 are protruded from each other.

Although this body member 3 is an embodiment in which one separate inner box 5 is fitted between the inner boxes 2 at the opposite ends, a plurality of separate inner boxes may be fitted depending on the purpose. In this case, the bottom wall 1 should be made larger and the number of lid flaps 7 should be increased.

The inner box 5 is made by using the expandable substrate B shown in FIG. 5 and bonding the bending margin 18 to the inner surface of the side plate 16 (see FIG. 1). This board B
is a bottom plate 15 having the same shape as the top plate 10 of the substrate A.
A side plate 16 having the same shape as the outer plate 9 of the board A is connected to the left and right edges of the substrate A, and a top plate 17 and a glue allowance 18 are successively connected to the edge of one of the side plates 16.
Folding flaps 19 are connected to the front and rear edges of the flaps 6, respectively.

When the double paper box is used, the inner box 2 at the pair of ends integrally connected to the body member 3 and the separate inner box 5 are provided with an elongated prismatic article having approximately the same shape as the inner box 2, and a separate inner box 5.
For example, when storing castella cakes, western cans, etc., fold the folding flaps 13 and 19 into both openings, insert the separate inner box 5 between the inner boxes 2 at the ends, line them up, and fold the lid flap 7 into each. Packaging is completed by folding it over the flap and inserting the insertion locking piece 14 into the inner box (see FIGS. 3 and 6) and covering it with the lid 4.

〔effect〕

As described above, according to the double paper box according to this invention, each inner box is fixed to the bottom wall, so it does not wobble during transportation, etc., and although it looks the same as conventional products, it is easy to manufacture. Since paper materials can be significantly saved, there are effects such as cost reduction.
