Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label for a blood bag on which a bar code is printed and a blood bag to which the label is attached.

[0002]

2. Description of the Related Art At present, a label for a blood bag printed with a product name, a capacity, an indication of a component, a manufacturer and the like is used. According to the company's request, a printed barcode is required. For those that can easily print barcodes, there are thermal printers that transfer ribbons and the cost is several hundred thousand yen.
When high-pressure steam sterilization was performed on the printed label, the printed portion was peeled off by the heat or steam of sterilization, or bleeding occurred, and transfer occurred to a sterilized bag or the like. For barcode printers that do not cause peeling or transfer of the printing section even when high-pressure steam sterilization is performed, expensive printers can be used for those that perform mass production. Blood bags such as triple bags, quadruple bags, etc. had too high amortization cost and could not be adopted.

[0003]

Accordingly, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, a bar code or a Lot print is performed on the label of the blood bag by using an inexpensive thermal printer to perform high-pressure printing. We succeeded in improving the print so that it would not peel off or transfer even after steam sterilization. [1] The present invention provides a blood bag label in which a bar code is printed on the surface of the blood bag label, and at least the bar code is coated with a transparent ultraviolet curable soft ink. [2] The present invention provides a blood bag label in which a bar code is printed on the surface of the blood bag label, and a transparent flexible synthetic resin is laminated on the bar code. [3] The present invention is characterized in that at least one half of the label is printed with a barcode and an entry of a blood bag manufacturer, and the other half of the label is printed with an entry of an operator. Provide a label. [4] In the present invention, a bar code is printed at least in one corner of the label, and the entry items of the blood bag manufacturer and the entry items of the operator are printed in other areas of the label [1] to [2]. ] Is provided. [5] The present invention provides a blood bag in which the label according to [1] to [4] is attached to the surface of the bag-shaped main body. The transparent ultraviolet-curable soft ink used in the present invention, even after being applied and cured on a label, maintains transparency and has relatively softness itself, when the label shrinks due to heat. It can shrink in synchrony. The transparent ultraviolet-curable soft ink used in the present invention is, for example, trade name: UVCM medium (UV ink), UVTML medium (UV ink), UVBF uncolored medium (UV ink), UV pack OP varnish SE-4 (U
V ink), UV anchor NO. 7 (UV ink) or the like can be used. The UV is ultraviolet light,
The CM refers to a cup, the TML refers to a thermosensitive label, the OP refers to an overprint, the BF refers to a business form, the anchor refers to a surface treatment of a base, and the SE refers to UV. It has no significance in the code of the shipping destination of the ink manufacturer. In addition, even if the ultraviolet-curable hard ink can be coated on the ultraviolet-curable soft ink, it can be used in combination with the soft ink. This is because the transfer to the label hardly occurs because the coating is performed on the soft ink. As the hard ink, for example, UV peel OP varnish up-2 (UV ink) or the like can be used. On the other hand, UV curable hard ink is a type of ink that hardens itself after it is applied to a label and cured, and even when applied to a label thickly, it cannot synchronize when the label shrinks due to heat and is likely to transfer to the label. is there. Therefore, the ultraviolet curable hard ink cannot be used alone. The transparent flexible synthetic resin that can be laminated on a label in the present invention is a resin that maintains transparency and flexibility even after being laminated on a label, and can shrink synchronously when the label is shrunk by heat. ,
For example, polyethylene terephthalate, polyethylene, polypropylene, polyvinyl chloride and the like can be used. After the blood bag has been subjected to high-pressure steam sterilization, any ultraviolet-curable soft ink or transparent flexible synthetic resin that does not substantially transfer to the surface of the bag-shaped body can be used. In the present invention, it is preferable to use an inexpensive thermal printer as a means for printing a bar code on the surface of the blood bag label.

[0004]

FIG. 1 is a plan view of a label 1 for a blood bag according to the present invention. A bar code is printed on the surface of the label 1 in addition to a product name, a capacity, a component display, a manufacturer, and the like. The surface of the cord is coated with a transparent ultraviolet curable soft ink.

Example 1 A label 1 on which a product name or the like is printed in advance is prepared, and a thermal printer (used ribbon: TR-4050, manufactured by Sony Chemical Co., Ltd., heat resistant temperature: 70 ° C.) is provided on the label.
Was used to perform barcode printing. The coating of the label with the transparent UV ink was performed using a coating device 2 as shown in FIG. The UV ink 4 is applied to the surface of the metal roll 3, the label 1 is sandwiched between the pressure roll 5 and the rubber roll 6, and the UV ink 4 is applied to the label 1 from the metal roll 3 via the rubber roll 6 while being fed.
Was applied. About 0.05cc of UV per label
The coating amount on the metal roll 3 and the feeding speed of the label 1 were adjusted so that the ink could be coated. This label 1 is attached to the surface of the bag-shaped main body of the blood bag and
A high pressure steam sterilization treatment was performed for 0 minutes, and the state of transfer of the print after sterilization was confirmed, but almost no transfer was observed. After coating the label with UV ink (or) in the same manner as described above, a label coated with UV ink is also prepared on the label, affixed to the surface of the bag-shaped main body of the blood bag, and subjected to high-pressure steam sterilization in the same manner as described above. The transfer of the print after sterilization was confirmed, but almost no transfer was observed.

FIG. 2 is a plan view of a label 11 for a blood bag showing another embodiment of the present invention. When the barcode printing is located in the center of the label as in the label of FIG. 1, it is difficult to partially coat the barcode printing with the UV ink, and it is difficult to coat the entire label surface with the UV ink. After collecting blood from the donor into the blood bag, it becomes difficult for the operator to enter the date of blood collection, blood type, etc., so that the left half or right half of label 2 (upper half, lower half or oblique) Arrange bar code, product name, volume, etc. (entry items of blood bag manufacturer) on half, and fill in the right half or left half (lower half, upper half, or oblique half) of label 2. The items such as blood collection date, blood type, etc. (entry items for workers) are arranged. Alternatively, only the barcode printing may be arranged at any one of the upper, lower, left, and right corners of the label 11 so that the UV coating or laminating process can be easily performed. By arranging the respective items in this manner, it is easy to coat the barcode with UV ink or to laminate a transparent synthetic resin described later, so that the operator can easily enter the blood collection date.

Example 2 In the same manner as in Example 1, a bar code is printed as shown on a label 2 in FIG. 3 and coated with UV ink, and then applied to the surface of the bag-shaped main body of the blood bag and several blood bags are stacked. A high-pressure steam sterilization treatment was performed to confirm the transfer of the print, but almost no transfer was observed.

In the present invention, a transparent flexible synthetic resin, for example, a polyethylene terephthalate film, a polyvinyl chloride film, a polyethylene film, a polypropylene film, etc., is coated on the label surface instead of coating the UV ink as in the above-mentioned label. By laminating, transfer, bleeding, and peeling of the barcode print to the bag-shaped main body can be prevented. The thickness of the laminate is 10 to 30 μm when laminating the entire label.
Is good. If it exceeds 30 μm, the gas permeability of the label affixing part of the bag-shaped main body is reduced by 10 to 20%, which is not preferable. If it is less than 10 μm, the barcode printing may be transferred to the bag-shaped body, which is not preferable. On the other hand, if it is to be partially laminated on the label, the thickness may be 10 to 100 μm.

Example 3 A label was prepared in the same manner as in Example 1, and a bar code was printed. After that, polyethylene terephthalate having a thickness of 30 μm was laminated on the label. When laminating a transparent flexible synthetic resin on this label,
This was performed using a laminating apparatus 22 as shown in FIG. Laminated film 24 made of polyethylene terephthalate having a thickness of 30 μm and rolls 24 a and 21 of label 21
a are prepared independently of each other, and the winding film 2 is wound up by a roller 27 while the laminate film 24 and the label 21 are adhered by a heater 26 arranged in the middle.
Laminating treatment was carried out by winding the film at No. 5. This label was affixed to a blood bag in the same manner as in Example 1, and the state of transfer of the print after high-pressure steam sterilization was confirmed. However, transfer, peeling, and bleeding of the barcode print were hardly observed.

[0010]

According to the present invention, even if a bar code printed on a blood bag to be commercialized by high-pressure steam sterilization is printed at a low price and printed with a simple thermal printer, the UV is printed on the printed portion.
By coating with ink or laminating a transparent flexible synthetic resin, the product does not peel or bleed with heat or steam during high-pressure steam sterilization, and the bar code print does not transfer to the bag-shaped body. Is possible.
