Abstract

PROBLEM TO BE SOLVED: To easily provide a label which is not easily peeled off and used as a raw material for a recycle process by making the background of a bar code transparent. SOLUTION: An egg container 1 is integrally formed from a transparent synthetic resin such as polyester, polyvinyl chloride, and has an upper cover 3 and a body part 4 which are openable through a hinge 2. The interior of each of the cover 3 and the body part 4 is partitioned to provide a plurality of conical egg storage parts 5a, 5b, each of which receives a half of an egg, and flanges 6a, 6b are provided on the outer peripheries of the cover 3 and part 4. A bar code 7 is directly printed on each of the storage parts 5a, 5b. The bar code 7 may be printed on an area of the flanges 6a, 6b of the cover 3 and part 4 at a proper position. For printing the bar code, a heat transfer printer, ink jet printer, laser beam printer, etc., are used and the material of a label is transparent and of the same material as the container 1, and a bar code may be printed on the label which is affixed onto the container 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermoplastic container provided with a bar code. In particular, the present invention relates to a plastic container provided with a barcode that facilitates management of eggs in a supermarket or the like, and that can be easily stacked during transportation and storage, collected and reused.

[0002]

2. Description of the Related Art In supermarkets and large stores,
2. Description of the Related Art Lightweight, transparent, integrally molded plastic containers are used for packaging products, for example, eggs. Such an egg container can be stably stacked without being bulky at the time of transporting, storing, and selling the egg, and is formed into a shape that does not easily damage the egg. In particular, in large stores such as supermarkets, barcodes are attached to such plastic containers, and the products are managed quickly and reliably by reading them with a barcode scanner or the like when necessary, such as when selling products. As an egg container provided with such a bar code, there is, for example, Japanese Utility Model Laid-Open No. 59-66786.

[0003]

Problems to be Solved by the Invention
In the egg container described in No. 6, a part of the egg container is integrally connected to provide a space for attaching a barcode, and a paper barcode label is attached thereto. When recycling such an egg container, it is necessary to peel off the attached barcode label. Further, since the container cannot be stably stacked due to the continuous portion, the container is bulky, and the attached bar code often peels off.

[0004]

SUMMARY OF THE INVENTION The present invention provides a thermoplastic container wherein at least the background portion of the barcode is transparent. Preferably, the barcode is printed directly on the transparent container. [Operation] A bar code having a transparent background is provided at an arbitrary position of the transparent container. Even if the background is transparent, there is no problem in reading the barcode. It is particularly suitable when the background is an egg of the contents.

[0005]

Next, the present invention will be described more specifically with reference to examples. FIG. 1 is a perspective view showing a specific example of a chicken egg container of the present invention. In FIG. 1, an egg container 1 is integrally formed of a transparent synthetic resin such as polyester and polyvinyl chloride,
It has an upper lid 3 and a body 4 that can be opened and closed via a hinge 2. The upper lid 3 and the body portion 4 have a plurality of (5 × 2 rows) a plurality of mountain-shaped egg storage portions 5a × 5b each capable of partitioning the inside and storing approximately half of a chicken egg, and have a flange portion 6a around the periphery. 6b. The bar code 7 is directly printed on the transparent egg housing portions 5a and 5b of the upper lid 3 or the body 4. The printing position of the barcode is not limited to this, and the upper cover or the flange 6 of the body provided with an appropriate area is provided.
a, 6b, etc. Various printing methods such as a thermal transfer printer, an inkjet printer, and a laser beam printer can be used for printing such a barcode. Alternatively, the material of the label may be the same transparent label as that of the container, and a barcode may be printed thereon and affixed to the container 1.

The hinge of the closed egg container may be cut off by forming a perforation on the hinge portion 2 of the egg container by a known method or by providing a thread for cutting.

[0007]

As described above, the plastic container of the present invention can be easily used as a raw material in a recycling process without peeling off a barcode label in advance. In the container of the present invention, a barcode is provided on an arbitrary transparent portion, and there is no specific portion to which the barcode is attached, so that eggs can be stably stacked and bulky at the time of transporting, storing, and selling chicken eggs. There is no.

Next, the present invention will be described more specifically with reference to examples. FIG. 1 is a perspective view showing a specific example of a chicken egg container of the present invention. In FIG. 1, an egg container 1 is integrally formed of a transparent synthetic resin such as polyester and polyvinyl chloride,
It has an upper lid 3 and a body 4 that can be opened and closed via a hinge 2. The upper lid 3 and the body portion 4 have a plurality of (5 × 2 rows) a plurality of mountain-shaped egg storage portions 5a and 5b capable of partitioning the inside and storing approximately half of the eggs, respectively. 6b. The bar code 7 is directly printed on the transparent egg housing portions 5a and 5b of the upper lid 3 or the body 4. The printing position of the barcode is not limited to this, and the upper cover or the flange 6 of the body provided with an appropriate area is provided.
a, 6b, etc. Various printing methods such as a thermal transfer printer, an inkjet printer, and a laser beam printer can be used for printing such a barcode. Alternatively, the material of the label may be the same transparent label as that of the container, and a barcode may be printed thereon and affixed to the container 1.
