Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package (container) for medicines, cosmetics, and the like, in which stored items such as prescribed indications and instructions for use are required to be properly stored. The present invention relates to a method for automatically detecting whether or not a package is securely bundled (stored) and a storage product used for the method.

[0002]

2. Description of the Related Art Bottles of pharmaceuticals, PTP-packaged pharmaceutical products, and packages of cosmetics, etc., need to be packaged (stored) with storages such as efficacy documents and instruction manuals. It is impossible to visually confirm the absence or absence of these efficacy documents or instruction manuals after the completion of the packaging process. Therefore, as a method of detecting the presence or absence of missing items such as the above-mentioned indications and instruction manuals, a method of comparing and inspecting the weight of the entire package, a method of seeing through using X-rays, etc., and applying a fluorescent substance to the paper In addition, a method of irradiating ultraviolet rays and observing a light emitting state has been proposed.

[0003] In addition, a ferromagnetic powder such as iron oxide is mixed with a printing ink, an effect book or instruction manual is printed using a so-called magnetic ink, and the printed paper is stored in a container. In addition, a method has been proposed in which the amount of magnetism of each container is measured, and based on the amount of magnetization, a missing item such as an efficacy statement or instruction manual is detected. That is, in a process of inspecting and sorting out a missing item of a detection object (storage item) contained in a container, a desired amount of magnetism is added to the detection object, and a magnetic field of the detection object is added to the detection unit. This is a method of comparing the detected value obtained by summing up the quantity and a set value to select whether or not the stored item is out of stock. There is also known a method of attaching a magnetic substance to a storage item.

[0004]

However, in the method of measuring the weight according to the above-mentioned conventional technique, the weight of an indication of use and instructions for use are relatively lower than the weight of a drug or the like stored in a package (container). When the amount is extremely small, there is a disadvantage that the detection sensitivity is lowered. In addition, the method using radiation such as X-rays requires a large amount of cost for safety problems and equipment for radiation protection. Impractical. Further, in the method of applying a fluorescent substance to paper, it is undeniable that it is necessary to consider the influence of the fluorescent substance on the human body, and it is never desirable to apply the method to a storage of medicines and cosmetics.

Further, the method using a magnetic ink has a drawback that the color of the ink is restricted because the magnetic powder is black or dark brown, and it is not possible to perform printing with an arbitrary color. The present invention has been made in view of the above-mentioned problems of the related art, and has a good detection accuracy, a simple structure, no safety or environmental pollution, and a relatively low cost. The present invention relates to a method for externally detecting a missing item such as an instruction sheet or instruction manual to be stored in a container after completion of a packaging process.

SUMMARY OF THE INVENTION The present invention is directed to a fine particle mainly composed of a metal having a property of being easily magnetized, which is an indication of the effect of pharmaceuticals and cosmetics, instructions for use, etc., contained in a container. This is a method for detecting a missing item of a stored item such as an instruction book or an instruction manual, which gives a desired amount of magnetism to a container containing a container containing fibers and detects the presence or absence of magnetization or the amount of magnetism. . Further, it is a paper to be used in the above-mentioned method, and is a storage material in which fine fibers mainly composed of a metal having a property of being easily magnetized are mixed. The present invention is intended to contain fine fibers mainly composed of a metal having a property of being easily magnetized in a storage such as an indication of use or an instruction manual, and apply a magnetic field from the outside after the packaging step to apply the fibers. Is magnetized, and its magnetic amount is detected.
In other words, utilizing the fact that it differs depending on the presence or absence of the indications and instructions for use, etc., it is possible to automatically and reliably detect the absence of the indications and instructions, etc. This is a method that allows characters, figures, tables, photographs, patterns, copy-forgery-inhibited patterns, etc., such as instructions, to be freely printed in any color.

[0007] The storage material used in the present invention is a mixture of fine fibers mainly composed of a metal having a property of being easily magnetized in a paper making process, and includes characters such as an effect book and an instruction manual. , Figures, tables, photographs, pictures, and tint blocks can be freely printed in any color. In the present invention, as a storage object, metal fibers are mixed or mixed with paper or plastic, so that the color of the surface is, of course, white,
Other colors can be freely selected. Therefore, printing without black as the color of the printing ink is also possible, and the color can be freely selected and color printing can be performed.

Further, iron oxide, nickel, stainless steel and the like are suitable for the easily magnetizable metal used in the present invention, and the workability, rust resistance, expected performance, price, etc. are comprehensively evaluated. Given that, stainless steel is preferred. The magnetic properties of stainless steels are related to the difference in crystal structure.Face-centered cubic austenitic stainless steels are usually non-magnetic like non-ferrous crystals such as copper, aluminum, and titanium. Ferritic, martensitic, or duplex stainless steels exhibit strong magnetism. However, even in austenitic stainless steel, metastable SUS301 and SUS304 are nonmagnetic in the solution heat treatment state, but exhibit strong magnetism when work-induced martensite is generated by cold working.

Therefore, it is more desirable that the metal having the property of being easily magnetized used in the present invention is appropriately selected from the above stainless steels.

Next, the storage items (paper) used in the present invention will be described. In the present invention, paper obtained by blending SUS304 stainless steel that has been drawn into a fine fibrous shape by being drawn by cold working was used as the paper for the storage material 2. Instead of paper, resin may be used. The content of the fine metal fibers is preferably in the range of 0.001 to 1.0 g / m ² , and more preferably, in the range of 0.01 to 0.1 g / m ² . The average length of the fibers is suitably 2 to 25 mm, preferably about 4 to 8 mm. The average diameter of the fibers is preferably in the range of 2 to 50 µm, and among them, 5 to 15 µm is appropriate. In the present invention, SUS304 stainless steel is used as a raw material of fine metal fibers, and is stretched by a cold working method and processed into fine fibers to impart magnetism. However, ferrite, martensite, or two-phase When the stainless steel of the system is processed into a fine fibrous shape, it shows stronger magnetism.

If the stainless steel obtained by processing the above stainless steel into a fine fiber cannot be obtained, it is possible to substitute a metal exhibiting strong magnetism, such as nickel, on the surface of resin fibers for plating. About 1,000 to 15,000 fine metal fibers described above are collected, bound with a water-soluble resin, and cut into a predetermined length and put into a papermaking process to obtain a storage article (paper) used in the present invention. . In addition,
