Description

      The present invention provides a lattice-like sewing machine in which cardboard sheets are provided with perforations in advance in the form of lattices so that creases and incisions can be easily made, and cardboard boxes of the desired size can be easily made. It relates to a filled cardboard.

      Traditionally, to make a box of the desired size with cardboard, it was necessary to draw a line with the correct dimensions using a ruler, cut it over it, and fold it.

This has the following drawbacks.
In the past, correct delineation was time consuming. Furthermore, it was also difficult to bend correctly on the drawn line. Also, the risk of being a distorted box was high due to dimensional errors and the inability to get the right angle. The present invention has been made to eliminate the above-mentioned drawbacks.

A grid-like perforation (2A) is provided on the cardboard (1).
The present invention is a grid-perforated cardboard with the above configuration.

A force was applied to the perforations to make the crease easier to insert.
The grid-like perforations make it possible to easily make folds at right angles.
The perforations act as a graph paper and can be easily dimensioned.
You no longer need to use the ruler to draw the correct line.
It became easier to cut because it was cut along the perforations.
In addition, since anyone can easily create a cardboard box of the minimum size required, the use of a home delivery service also has the effect of minimizing the charge.
Furthermore, the time required for wire drawing and the time for adjustment for correct bending are lost, and work efficiency is significantly improved.

It is a basic plan view of the present invention. It is an explanatory view showing a limited application example of the present invention. It is an explanatory view showing an example of use of an applied product of the present invention.

Hereinafter, modes for carrying out the present invention will be described.
A grid-like perforation (2A) is provided on the cardboard (1).
The present invention has the above structure.
When using the present invention, the auxiliary lines indicating the width, depth and height of the box to be created are written along the perforations as the cut line (3) and the valley fold line (4), and the sewing machine of the cut line (3) Cut through the eyes, glue the necessary parts, and fold along the perforations of the valley fold line (4) to obtain a cardboard box of the desired size.
Another embodiment of the present invention will be described.
When perforations can not be arranged in a wide range due to reasons such as strength, the type of box to be created can be limited to a limited pattern like perforations (2B).

1 Cardboard 2A Perforations arranged in a grid 2B Perforations arranged in a predetermined shape 3 Example of use Cut and cut lines (solid line)
