Description

[Detailed Description of the Invention] 3. 1ff-Law Theory of the Invention II Industrial Application Field The present invention relates to a method for manufacturing trays with barcode marks used for packaging and displaying food products in supermarkets and grocery stores. Regarding.

[Prior art] Packaging trays used in conventional supermarkets (ZI-me) to display foods are made of plastic or styrofoam, and after food is placed inside the tray, the top surface is made transparent. It is wrapped in film, and barcode mark stickers are affixed to the sides and top at appropriate locations.

The reason for pasting the barcode mark sticker in this way is that if the eight-code mark is printed on the plastic plate before being molded into the tray, the barcode will be printed due to shrinkage of the plastic plate when the tray is molded. This is because the mark is deformed and cannot be recognized by an optical reader during use. Therefore, usually food stores have to affix barcode mark stickers one by one, which requires work to affix the stickers, which has the drawback of increasing labor costs.

[3? ¥1! The problems that +1 tries to solve” End of the IJ
In order to solve the above-mentioned drawbacks, I printed a barcode mark on a paper pattern that could be made into a tray shape with discontinuous four sections, and pasted a plastic film such as waterproof vinyl on the back side. By heat-pressing and molding the whole into a tray shape, food W with a barcode mark pre-attached is produced.
You can now make packaging trays.

[Means for Solving the Problems] The tray manufacturing method of the present invention involves forming a cut-out portion to make each body part discontinuous at a portion of the body part 411pJ of the formed tray in the tray Kawahara paper. In addition, a barcode mark is printed on the outside surface of the base paper that will become the body of the molded tray, and a waterproof thermoplastic film is pasted on the inside surface of the tray. It is configured to be shaped into a container shape.

``Example'' Next, an example of the first embodiment will be described in detail with reference to an example shown in the accompanying drawings.

In Figures 1 and 2, the symbol IA indicates a tray, which has a rectangular bottom part 2 on which a stamp 1n (original paper pattern) of cardboard or plastic paper is molded, and from the four sides of the Fourteen parts 3a, 3b, 3c, and 3d are arranged in a row with an angle #I slightly outward from the vertical direction to form four parts 4.

A film 5 made of polyethylene or vinyl is pasted on the inner surface of the tray, and each of the rising body parts 3a,
The discontinuous portion 6 between 3b, 3c, and 3d is connected by a film 5. Furthermore, a bar code Murtagh is printed on the outer surface of the rising body portion 3c.

Next, the above-mentioned tray forming process will be explained in Figures 3 to 6.
I will explain from the figure 1.

In Fig. 3, numeral 1 indicates L (paper, 2 corresponds to the bottom of the tray, 3a to 3d correspond to the 18th part, 8 is the base of the 18th part (the part that becomes the fold f(8), 1
0 indicates the outline for punching of the Δ1i paper for the tray.

This base paper has triangular shapes at locations corresponding to the discontinuous portions 6 at the four corners of the body portions 3a to 1d in the tray formed as shown in No. 11A. /J Including 9a, 9b, 9c, divide by yJ, and print the 8-code mark 7 on the outside surface of the tray of the required portions 3a to 3d corresponding to ff4 copy as shown in Figure 4. .

Next, as shown in FIG. 5, a waterproof plastic film 5 is laminated on the opposite side of the base paper to the barcode mark printing side, that is, on the inside of the tray, and the laminated base paper is lined with the outline line 10 for the tray. νJ, and the body parts 3a to 3d are raised to form the tray shown in FIG.

The tray thus formed has a paper base.

Moreover, since the four corners of the body are cut out in advance, the 11-1 paper pattern will not be distorted during heat molding, and the pre-printed barcode mark will not be deformed.

Therefore, the barcode mark maintains its correct shape, allowing the reader to accurately detect the symbol.

Also, the four corners of the body of the pattern are cut out, but the f on the four sides
Since the f4 parts are connected to each other by the plastic film on the inner surface, they are held in an upright shape and can be used as a tray without any inconvenience, and there is no risk of leakage even with water-containing substances.

[Effects of the present invention] In the present invention described above, since it is possible to mold the food +7+ tray on which the /H code mark is printed in advance, the code printed on the tray at a food one-item store or processing factory can be molded. All you have to do is pack the food according to the
There is no need to affix a barcode mark sticker as in the past, and the cost of the sticker can also be reduced, so the overall processing cost and time can be saved.

Claims (1)

[Claims] Cutting parts are formed in the base paper for trays at locations corresponding to the four corners of the body of the forming tray to make each body discontinuous, and in the portion of the base paper that will become the body of the forming tray.
Moreover, a method for producing a tray is characterized in that a barcode mark is printed on the outer surface of the tray, and a waterproof thermoplastic film is pasted on the inner surface of the tray, and then heated and shaped into a container shape. .
