Abstract

<P>PROBLEM TO BE SOLVED: To form a carved seal of a clear outline without breaking corrugated cardboard. <P>SOLUTION: In a method for forming the carved seal 3 in the corrugated cardboard S by pressing the cardboard S between facing molds 11 and 12, by forming a flat surface 13 and a projection 14 in the molds 11 and 12 respectively, narrow space parts corresponding to the shape of the carved seal 3 are formed in the molds 11 and 12, and the cardboard S is crushed in the thickness direction in the parts. Since a step is formed along the outline of the carved seal 3 without strongly stretching the cardboard 3, the carved seal 3 of the clear outline can be formed without breaking the cardboard S. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for beautifully imprinting a mark on a corrugated cardboard, and a molded article having a mark imprinted by the method.
[0002]
[Prior art]
In recent years, molded articles formed by pressing corrugated cardboard may be used as containers or partitioning materials for various products, and it is conceivable that such molded articles may be engraved with designs, characters, and the like along with the press. Have been.
[0003]
At the time of this engraving, as shown in FIG. 4, a convex portion 53 and a concave portion 54 corresponding to the shape of the engraving 55 are provided on the opposite molds 51 and 52, and the cardboard S is pushed out to the concave portion 54 by the convex portion 53. I do. At this time, the same interval as the surrounding portion is kept between the convex portion 53 and the concave portion 54.
[0004]
[Problems to be solved by the invention]
However, in the above-described method, the corrugated cardboard S may be broken by being pulled at the corners of the convex portion 53 and the concave portion 54, and the draft slope becomes long in the contour portion of the stamp. However, there is also a problem that is not clear.
[0005]
Therefore, an object of the present invention is to provide a method for engraving a sharp contour without causing breakage of corrugated cardboard and a molded product thereof.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a method of stamping corrugated cardboard by pressing the cardboard between opposed molds. The cardboard was crushed in the thickness direction at that portion, and the stamp was formed on the press-formed body by this method.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
[0008]
The container shown in FIG. 1 is used for home delivery of pizza, and includes a body 1 and a lid 2. The body 1 and the lid 2 are both formed by pressing corrugated cardboard, and a mark 3 is placed in the center of the lid 2. A raised portion 4 is formed around the inscription 3 in order to enhance gazeability.
[0009]
As shown in FIG. 2, the stamp 3 is inserted at the same time when the lid 2 is formed by pressing the cardboard S between the opposing dies 11 and 12.
[0010]
Here, a flat surface 13 corresponding to the back surface of the raised portion 4 is formed on the mold 11, and a convex portion 14 corresponding to the shape of the stamp 3 is formed on the mold 12.
[0011]
When the press is performed by using the dies 11 and 12, the interval between the dies 11 and 12 becomes narrower than other portions in the stamp 3, and the corrugated cardboard S is crushed in the thickness direction.
[0012]
At this time, since the corrugated cardboard S is not pulled too much and a step is formed along the contour of the mark 3, the corrugated cardboard S is not broken, and as shown in FIG. You can enter.
[0013]
Also, as shown in FIG. 3, the protrusions 14 of the mold 12 are slightly protruded, and correspondingly, a shallow recess 15 is provided in the mold 11, and the cardboard S is crushed between the protrusions 14 and the recesses 15. Even in this case, as in the case described above, it is possible to insert a clear mark 3.
[0014]
In this embodiment, the corrugated cardboard is crushed at the inner part of the inscription 3, but the corrugated cardboard may be crushed at the outer part of the inscription 3 so that the inscription 3 appears to be raised.
[0015]
In addition, in FIG. 1, characters indicating a company name are depicted as an example of the engraving 3, but according to the above-described method, the engraving 3 of the figure can be sharpened like a geometrical company emblem or a lattice pattern. You can also enter.
[0016]
【The invention's effect】
As described above, when engraving is performed by the method according to the present invention, the corrugated cardboard is not pulled too much, and a step is formed along the contour of the engraving. , And the molded article inscribed in this way has excellent appeal.
[Brief description of the drawings]
FIG. 1 is a perspective view showing a stamped molded body according to the present invention; FIG. 2 is a cross-sectional view showing a stamping process by the above-mentioned press; FIG. Sectional view showing the process of engraving with a conventional press.

Claims (2)

In the method of engraving corrugated cardboard by pressing the corrugated cardboard between the opposing molds, a narrow space is provided on the opposing mold corresponding to the shape of the engraving, and the corrugated cardboard is cut in the thickness direction at that part A method of stamping corrugated cardboard, characterized by crushing. What is claimed is: 1. A stamped corrugated molded body, characterized in that the corrugated cardboard is stamped in the thickness direction in accordance with the shape of the stamp.
