Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic container for injections (plastic bag or plastic bottle) having a coloring portion at a hanging portion and having a high discriminating power.

[0002]

2. Description of the Related Art A plastic container for an injection (including an infusion) is usually composed of a main body (a body, a mouth, and a suspension (all integrally molded)) and a cap (a plug body: a rubber stopper). And is used as a plastic container for injections. Conventional plastic containers for injections are transparent or translucent and have various shapes. Labels are attached or printed on the body of the product to indicate the product name, application, components, etc., and distinguish it from other products. Has been made. Further, there is a container cap (plug) that is colored for identification (for example, see Japanese Utility Model Publication No. 3-37622) and a product in which a serial number and an expiration date are printed on a hanging portion. There is no plastic container for injections that has added an identification mark to enhance the effect of distinguishing it from other products.

[0003]

However, plastic containers for injections have almost the same structure, and as described above, there is some difference in shape but no significant difference.
In addition, the color of the cap of the container for identification is widely used in the industry, and similar colors are often used, which not only reduces the identification power but also causes confusion with other products. Further, the serial number and the expiration date printed on the hanging portion have no effect on the identification of the product.

[0004] Injections or infusions are identified by the shape of the label or container and the color of the cap. However, as described above, the plastic container for injections has a reduced overall discriminating power.
In recent years, medical accidents have occurred in medical practice where the wrong drug is administered. Misadministration of injections having different effects may lead to serious medical accidents. An object of the present invention is to provide a plastic container for injections having a high discriminating power in order to reduce such unexpected medical accidents.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a plastic container for an injection having a coloring portion at a hanging portion and having a high discriminating power. Preferably, the present invention is a plastic container for an injection with high discriminating power, in which the colored portion of the hanging portion is the entire hanging portion. More preferably, the colored portion of the hanging portion is the same color or substantially the same color as the colored portion of the cap portion (plug portion), or the same color as the color of the tamper seal attached to the top surface of the cap portion (plug portion). It is a plastic container for an injection with high discriminating power, which is almost the same color or the same color or almost the same color as the basic color (ground color most frequently used in the label) of the label attached to the plastic container body. The term “injection preparation” in the present invention includes not only an injection preparation containing a pharmaceutically active ingredient for treating a disease but also an infusion preparation mainly intended for calorie supplementation.

[0006] It is usually preferable to color the hanging portion over the entire hanging portion, but it is preferable to color the hanging portion on one side, the upper or lower half, and the upper side.
It can also be performed on a part of the hanging part, such as the / 3 part. Also, in the present invention, the hanging portion is colored by using a character, a symbol, a pattern, or a combination thereof to serve as an identification display, so that the discriminating power can be further enhanced. Specifically, the name of the manufacturer, the name of the product, or the like may be displayed in white characters or colored characters on the hanging portion. In addition, identification information such as a manufacturer mark and a product abbreviation may be displayed.

In the present invention, the color of the hanging portion is made the same color or almost the same color (same color system) as the basic color of the label, the same color or almost the same color as the colored cap portion, and affixed to the cap portion (fusion). By making the same color or almost the same color as the tamper seal to be used, and by making the three portions of the hanging portion, the basic color of the label and the colored cap portion the same color as much as possible, the discriminating power from other products can be further enhanced. .

[0008] The coloration of the hanging portion may be performed by fusing, pseudo-fusing, or pressing a colored film or a film having simple colored characters or symbols on the hanging portion, or by using a pad printing method or a hot stamp on the hanging portion. And a method of applying a pigment directly.

[0009] For example, as a method of manufacturing a plastic container body for injection having a colored portion on a hanging portion, a colored identification film or molded product is inserted into a mold, and direct blow molding is performed. Then, there is a method in which a film for identification or a molded product is fused, pseudo-fused or pressure-bonded to a plastic container which is a blow molded product.

[0010] The melting and extruding temperature of the resin when extruding the resin melted from the molding machine by the extruder depends on the melting temperature of the resin used, but is generally 160 ° C to 280 ° C. The inserted identification display film or molded product is made of the same material as that of the plastic container or a combination of materials that can be fused, quasi-fused or crimped, or a laminated product having such a material on the fused surface. Is used.

For example, polypropylene resin (PP resin) and polypropylene film (PP film), polyethylene resin (PE resin) and polyethylene film (PE film), PP resin and PE film, PE resin and PP film, PE resin and PE There are combinations such as laminated aluminum evaporated polyethylene terephthalate film (PET film). There is no problem with the thickness of the film as long as it has the rigidity required for insertion.

The method of inserting the film includes a method of inserting a roll-shaped film into a mold, and a method of inserting an identification display film or a molded product formed by a robot into a hanging portion of the mold.

[0013] In the coloring method by pad printing, air or ink of natural drying is applied to a soft rubber pad of a pad printing machine.
V ink (ultraviolet curable ink) is applied, and a pad is pressed against the hanging portion of the molded plastic container for injections to transfer and color the ink.

In a coloring method using a hot stamp, for example, a corona discharge is carried out on a hanging portion of a molded plastic container for injection to improve transfer adhesion, and a thermal transfer foil is applied to a thermal transfer foil at about 100 ° C. using a thermal transfer machine. By pressing against the hanging part with a pressure of about 8 kg / f, the foil is transferred to the hanging part and colored.

[0015]

The present invention will be described in more detail with reference to the following examples.

Embodiment 1 As shown in FIG.
A 1 mm colored polyethylene film (orange) 1 was inserted into both sides of the hanging portion of the mold 2, and linear low-density polyethylene (LLDPE) “Mortec 3” melted by an extruder of a molding machine was used.
500Z "(made by Idemitsu Petrochemical Co., Ltd.) is extruded into a cylindrical shape at approximately 200 ° C. (parison 3), the extruded parison is sandwiched by a mold, and compressed air (4 to 5 kg / cm ^{2) is} blown from a portion serving as a container opening by a blow pin 4. ) Was blown, the parison was inflated and pressed against the inner wall surface of the mold, and the colored film (orange) inserted into the hanging portion of the mold was fused. After the cooling time, the mold was opened and the molded product was taken out. The portion protruding from the mold was cut with a cutter to produce a plastic bag for injections in which the entire hanging portion 5 was colored orange as shown in FIG. By using the obtained plastic bag for injections in combination with a cap (plug) 6 colored in orange, the discriminating power of the injections could be enhanced.

Example 2 The lower half of the hanging portion (half from the end) was substantially the same as in Example 1 except that light blue polypropylene having a thickness of 0.1 mm was inserted into the lower half of the hanging portion of the mold. ) Was manufactured in a plastic bag for an infusion solution, which was colored blue.

[0018]

According to the present invention, the use of the plastic container for injection having a colored portion in the hanging portion enhances the discriminating power of medicines at medical sites handling a wide variety of injections and infusions, and allows the administration of medicines to be administered. Because there is almost no mistake,
An unexpected medical accident can be prevented beforehand.
