Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to gloves having antibacterial properties.

0002

[Prior Art] Conventionally, sanitary gloves made of polyethylene or other resins have been used for work that requires hygiene such as food processing, medical work that involves the risk of secondary contamination by microorganisms, and biotechnology. It is used for related work. However, since these gloves are not made in a sterile environment, they are not necessarily sterile, and even if the gloves are new, they often have microorganisms attached to them, and bacteria may be contaminated with food. In the case of germs that cause spoilage or food poisoning, coming into contact with food through gloves could cause major problems. Furthermore, when used in medical work or biotechnology-related work, the gloves do not have antibacterial properties, making it difficult to handle them when disposing of them after use.

0003

[Problems to be Solved by the Invention] An object of the present invention is to ensure that it can be used safely in the food processing industry, etc. without causing food spoilage or food poisoning, and that it can also be used in medical work and biotechnology-related work. The present invention aims to provide sanitary gloves that can be easily handled afterwards.

0004

[Means for Solving the Problems] The present invention relates to sanitary gloves that are formed from a plastic sheet containing silver ion-containing soluble glass from which silver ions can be gradually eluted, and that have antibacterial properties themselves. It is. In the present invention, silver ion-containing soluble glass that can elute silver ions at a constant rate is used as an antibacterial agent. Meltable glass is a general term for glasses whose composition has been adjusted in consideration of the physical and chemical properties of the glass so as to have a controlled melting rate, and is already known in itself. Therefore, in a silver ion-containing soluble glass to which a silver compound is added, silver ions can be eluted at a fixed rate over any period of time from several hours to several years. The eluted silver ions then exert an antibacterial effect against mold and bacteria.

Silver ion-containing soluble glass is preferably dispersed in a plastic sheet in the form of fine particles in order to provide stability during processing and to prevent the substance from transferring from gloves to objects to be manipulated such as food. I am forced to do it. That is, the sanitary glove of the present invention, as shown in FIG. 2, is composed of a plastic sheet 7 in which silver ion-containing soluble glass 6 is dispersed and contained.

[0006]Although this glove may have a single-layer plastic sheet structure, it may have a multi-layer structure as shown in FIG.
For example, the plastic sheet layer 7 containing the silver ion-containing soluble glass 6 may be located only on the outer surface of the glove that comes into contact with an object to be operated such as food. Of course, the gloves can also be embossed for the purpose of preventing slippage, preventing blocking, improving texture, etc.

In the present invention, such silver ion-containing soluble glass is contained in the material for forming the plastic sheet as fine particles of 200 μm or less, preferably 50 μm or less. Here, when the particle size becomes 200 μ or more,
No longer uniformly dispersed in the forming material. Moreover, its content is preferably 0.005% to 15% by weight. 0.05
If it is less than 15% by weight, the antibacterial effect of silver ions will be insufficient, and if it is more than 15% by weight, it will be difficult to mix it into the forming material, which is not preferable. As the material for forming the plastic sheet, thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride, polyamide, ethylene vinyl acetate copolymer, saponified ethylene vinyl acetate copolymer, polyester, etc. can be used, but are not limited to these. . Further, the thickness of this plastic sheet is not particularly limited, but preferably 10 to 100 microns is used.

[0008] As a method for dispersing and incorporating silver ion-containing soluble glass into a plastic sheet, the following method can be used. (1) Using a Banbury type mixer or a roller type mixer, a thermoplastic resin in a heated and molten state and the silver ion-containing soluble glass are mixed to create a masterbatch. (2) Mix the masterbatch with any thermoplastic resin, and disperse and incorporate silver ion-containing soluble glass into a plastic sheet using the conventionally known T-die method or inflation method.

When using the T-die method or the inflation method, it is necessary to incorporate silver ion-containing soluble glass only on one side of the plastic sheet by a conventionally known coextrusion method, or to use two or more types of thermoplastic resins. Naturally, it is also possible to impart functions such as strength and barrier properties. As shown in FIG. 1, the method for making the gloves is to prepare two plastic sheets 1 and 2 of single-layer or multi-layer structure so that at least the part containing silver ion-containing soluble glass is located on the outer surface of the glove. The sanitary glove having antibacterial properties of the present invention can be produced by overlapping the gloves, heat-sealing them together along the glove peripheral part 4, and cutting them along the glove peripheral part 4. Also, at this time,
Of course, it is also possible to reduce waste of the plastic film by making the entrance of the glove be at the side edges 3, 3' of the plastic film, or by heat sealing the gloves so that they face each other.

0010

Effects of the Invention: The antibacterial gloves of the present invention have the effect of sterilizing microorganisms attached to the gloves, so unlike conventional sanitary gloves, the gloves are not contaminated with microorganisms and are suitable for food processing. In industry, microbial contamination of food from gloves can be completely prevented, and since the gloves themselves have antibacterial properties, microorganisms that adhere to the gloves are quickly sterilized even after use, so they can be used in medical work and biotechnology. This also has the effect of simplifying handling and disposal in related operations.
