Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a method for manufacturing a packaging box.

<Prior Art> Conventionally, when manufacturing a box using single-sided corrugated cardboard a, the method shown in FIG. 6 is common.

(b) Attach single-sided cardboard a to cardboard b with the stepped part inside (adhering side).

(b) After pasting them together, cut them into the expanded shape of the box.

(c) After cutting out the mold, assemble it into box c.

<Problems to be Solved by the Invention> In this way, pasting the cardboard b onto the single-sided cardboard a increases the strength of the box, and
This was to prevent the corrugated portions of the cardboard from being visible to the outside.

However, when such bonding is performed, only a smooth surface appears on the surface of the box. As a result, even if printing or the like is applied to the surface, it is no longer possible to give the user a new feeling.

On the other hand, for example, in Japanese Utility Model Application Publication No. 55-105339, in a corrugated paperboard in which corrugated paper is laminated between the cover and back paper, the cover and the corrugated paper are formed into a predetermined shape such as letters. A corrugated paperboard is disclosed which is cut and pressed against the backing paper to display characters and the like.

In the case of this corrugated paper, the cover and the wavy paper are cut into predetermined shapes such as letters, and the cut portions are crushed toward the backing paper, so that the letters, etc. can be expressed in the recesses. However, even with this corrugated paperboard, what appears on the surface is only a smooth cover and backing paper. More importantly, when the cut portion is pressed against the backing paper, what appears in the recess is a pressed, smooth cover. In other words, the wavy paper is only sandwiched between the cover and back paper, and does not appear on the surface, making it impossible to express the difference between the wavy appearance and the smooth front and back paper. .

Further, Japanese Patent Publication No. 59-49194 discloses a method in which a resin is applied to the surface of the cover to express characters, etc., and then the cover is bonded to a single-sided cardboard. However, even with this corrugated paper, what appears on the surface is only the smooth cover and backing paper, and what's more, the letters etc. are only expressed by applying resin, so it lacks a three-dimensional effect. It is.

<Means for Solving the Problems> Therefore, the present invention provides a method for assembling a box by pasting together a plurality of sheet-like bodies and then cutting out the box in the unfolded state, which has the following configuration. We solve the above problem by providing what we have.

In the present invention, one-sided corrugated cardboard is selected as the outermost sheet among the plurality of sheet-like bodies, and a substantially smooth sheet-like body is selected as the sheet-like body arranged inside the cardboard. Select.
After cutting out patterns, characters, etc. from this single-sided corrugated cardboard, the single-sided corrugated cardboard is bonded to the above-mentioned planar sheet-like body with the corrugated portion facing forward. Note that it is sufficient that the sheet-like body disposed on the inside is substantially smooth, and even if the unevenness is formed by embossing, etc., the unevenness is smaller than the unevenness of the corrugated portion of the single-sided corrugated board. If so, it should be substantially smooth.

<Function> In the present invention, after cutting out patterns, characters, etc. on single-sided cardboard, the single-sided cardboard is bonded to the above-mentioned planar sheet-like body with the corrugated portion facing forward. In the case of the box manufactured according to the present invention, the corrugated portion of single-sided corrugated cardboard appears in the main part thereof. Then, a substantially smooth sheet-like body arranged on the inside appears only in the portion of the single-sided cardboard where the patterns, letters, etc. have been cut out. Therefore, in the case of the box manufactured according to the present invention, the large uneven portions due to the corrugations of the single-sided corrugated board and the substantially smooth portions appearing from the die-cut portions effectively appear on the surface and are extremely abundant. It is possible to express a three-dimensional effect.

<Example> An example of the present invention will be described below based on the drawings.

FIG. 1 is a process explanatory diagram of the present invention, and the method for manufacturing the box will be explained based on FIG.

(b) Cut out patterns 3, letters, etc. on the single-sided cardboard 1.

(b) Laminating single-sided cardboard 1 and cardboard 2 (other sheet-like materials are also acceptable).
do.

At this time, by changing the colors of both 1 and 2, the picture 3, characters, etc. are further emphasized.
Alternatively, a pattern or the like may be applied by printing.

In this bonding, the corrugated cardboard 2 is bonded to the back side of the single-sided corrugated cardboard 1 with its stepped portion facing up.

(c) After pasting together, cut out the box to make it in the unfolded state.

(d) Assemble to complete the box body.

In the example, two sheets were pasted together, but by using three or more sheets, a more three-dimensional pattern can be created. Further, in this case, it is also preferable that the shapes of the die-cut sheets are different from each other.

FIGS. 2 and 4 show perspective views of the box completed by the above manufacturing method. Also, in Figures 3 and 5,
A developed diagram of each is shown. In both developed views, dotted lines indicate mountain fold lines, and dashed lines indicate valley fold lines.

<Effects of the Invention> As described above, in the present invention, after cutting out patterns, characters, etc. on the sheet-like body disposed on at least the outermost layer, a process of pasting each sheet-like body is performed, so that the completed box It is possible to display three-dimensional patterns and letters on the body, and it is possible to give the surface of the box a distinctive feature. Moreover, since the patterns and letters are expressed by die-cutting, it is suitable for mass production, and compared to the conventional process, only one step is added.
It is possible to manufacture a box having a novel surface shape.

Claims (1)

[Scope of Claims] 1. In a method of assembling a box by pasting together a plurality of sheet-like bodies and then cutting out a box in an unfolded state, the outermost layer of the plurality of sheet-like bodies is A single-sided cardboard is selected as the sheet-shaped body to be arranged, a substantially smooth sheet-shaped body is selected as the sheet-shaped body to be disposed inside the sheet-shaped body, and patterns, characters, etc. are cut out on this single-sided cardboard.
