必要となっている。2. Description of the Related Art In particular, nosocomial infection (MRSA), which has been a problem in hospitals, has spurred products with antibacterial action, and has been used by other people such as ball-point pens, telephones, and train straps. Excessive cleanliness syndrome, such as the inability to hold, is gaining public attention. On the other hand, regarding the bactericidal action that kills the bacteria and reduces the number, or the so-called antibacterial action that includes the bactericidal action that suppresses the bacteria so that it does not increase further, the weather conditions of high temperature and high humidity in Japan are such as mold. Since it is suitable for the generation and reproduction of microorganisms, there is a need for a product that can improve and maintain its antibacterial properties even for cleaning the living environment.

的としている。Therefore, an easily openable can lid in which a resin-containing protective film of an antibacterial metal carboxylate or a titanium oxide film is coated on the outer peripheral surface of the container, for example, as disclosed in JP-A-5-278745. Beverage cans and the like having excellent hygienic properties have been proposed. However, for example, in glass containers that are often used for medicine, cosmetics, and eating and drinking, there are many cases where the lid is repeatedly opened and closed for a relatively long period of time. It is hoped that the effect will be sustained,
When coating a resin film containing an antibacterial agent, unlike other materials, there is a problem that the glass material packaging container has poor adhesion between the glass material and the surface coating film. Further, when a coating layer containing an antibacterial agent is further provided on the outer surface of the glass container, the antibacterial agent component contained in the resin composition or the like is usually in a dispersed state, and the antibacterial component that directly contacts the bacteria is limited to a part thereof. Although it is a negative sense that it suppresses the growth of general bacteria, it is difficult to expect an antibacterial action in a positive sense. In addition, it is not satisfactory from the viewpoint that it is desired that the antibacterial action is sustained due to the growth of general bacteria, mold generation, putrefaction and the like. The present invention provides an antibacterial processed glass container in which an undercoat layer is provided on the outer peripheral surface of the glass container, and then a coating layer made of a topcoat layer containing an antibacterial agent is formed and baked and coated, or glass. 0.2 on the outer surface of the container
% Antibacterial agent and surface irregularity forming agent are mixed to form a coating layer of a resin composition, and 0.2% or more antibacterial agent and anti-settling agent are formed on the outer peripheral surface of the glass container. It is an object of the present invention to provide an antibacterial processed glass container which is formed by forming a coating layer made of the blended resin composition and baking it.

To form a thin film of a topcoat layer containing an antibacterial agent on the surface of the resin composition, or to mix a surface irregularity-forming agent into a resin composition containing an antibacterial agent to finish it in a matte finish to increase the surface area, The antibacterial agent is formed on the surface of the coating film layer by forming a coating film layer of the antibacterial agent-containing resin composition mixed with an anti-settling agent for forming a swelling dispersion or gel structure in the product and baking it. A configuration that allows cohesive migration,
Alternatively, a film is formed as a thixotropic agent for increasing the contact area with an antibacterial agent mixed by forming irregularities and for forming a swollen gel structure or the like in the resin composition by an antisettling agent to prevent sedimentation of the antibacterial agent mixed. By adopting a form in which it migrates and agglomerates to the surface side of the layer, the effect of the mixed antibacterial agent can be exhibited and the effect can be maintained for a long period of time.

When the amount is less than the above range, the antibacterial action and its sustainability are insufficient, while on the other hand, the antibacterial property hardly changes even when used in excess of the above range, and there is no particular advantage in terms of the sustainability, and further antibacterial effect is obtained. You can't expect it, and it will be a factor of cost increase. Further, the corrosion resistance and weather resistance of the coating layer are deteriorated, the surface is likely to be roughened, and it may cause discoloration of darkening, which is disadvantageous in that the surface gloss is impaired visually.

Next, when a topcoat layer containing an antibacterial agent is provided, the surface thin film functions to exert an antibacterial effect because the antibacterial agent is concentrated and contained in the surface thin film. In addition, by adding a surface irregularity forming agent to a resin composition containing an antibacterial agent, the surface area of the glass container is actively provided with irregularities to increase the surface area, and as the surface area increases, the action of the antibacterial agent is increased. Work to be effective. Next, by adding a settling inhibitor to the resin composition containing the antibacterial agent, the contained antibacterial agent is positioned on the surface side of the coating layer as much as possible, so that the antibacterial agent can be easily aggregated and the antibacterial effect and the durability can be exhibited. work. Further, a film layer is formed of a resin composition in which a surface unevenness forming agent and / or an anti-settling agent is properly combined with an antibacterial agent, and the synergistic effect of these forms an antibacterial effect and the effect for a relatively long period of time. Work to be sustainable.
