More specifically, it relates to a container made of a polymer laminate in which an antibacterial agent or the like is added to the surface of the container for the purpose of preventing the growth of mold and the like.

ない。2. Description of the Related Art It has been known for a long time that microorganisms such as mold grow on the surface of plastic products placed in hot and humid conditions in bathrooms and the like. Therefore, not only the appearance is impaired, but also the mold spores are considered as one of the causes of symptoms such as allergy. Therefore, various antibacterial agents are added to the plastic to prevent the growth of microorganisms such as mold. These are no exception for containers such as shampoos.

移行し、ついには抗菌剤が内容物に移行していた。Polyethylene and polypropylene are usually used in these containers. The innermost layer of the container is a resin layer containing no antibacterial agent, the outermost layer of the container is a resin layer containing an antibacterial agent, and the intermediate layer is a container. Most of them are so-called burr-added resin layers that appear during molding. However, these resins easily pass through additives such as organic antibacterial agents, and during molding, even though no antibacterial agents are added to the innermost layer of the container (the layer in contact with the contents) during molding. In addition, the antibacterial agent added to the intermediate layer and the outermost layer was transferred to the innermost layer, and finally the antibacterial agent was transferred to the contents.

くなる。Although a highly safe antibacterial agent is usually used in such a container, migration of the antibacterial agent to the contents is prevented from the viewpoint of protection and safety of the contents. It was left as an issue I wanted to do. In addition, when an antibacterial agent is added to a resin that does not easily transfer, for example, a resin such as a polyester resin, a polyamide resin, or an ethylene / vinyl alcohol copolymer resin, it is possible to prevent the transfer of the antibacterial agent to the contents. Since the transfer of the antibacterial agent to the outermost surface of the container is also hindered, the growth of microorganisms such as mold cannot be inhibited.

剤に対する効果を考慮して選択される。The details will be described below. The reason why polyolefins such as polypropylene and polyethylene and polystyrene easily migrate and elute the antibacterial agent is considered to be that the molecular chains are wide and the drug easily passes through. Polyvinyl chloride resin, polyvinylidene chloride resin, polyester resin,
Acrylic resin, polyamide resin, ethylene / vinyl alcohol copolymer resin, acrylonitrile resin, polycarbonate resin, etc. are considered to be difficult to transfer the antibacterial agent because the molecular chain is narrow and it is difficult for the drug to pass through. It is also considered that the solubility of the antibacterial agent in the resin is related. In practice, it is selected from these resins in consideration of the effect on the antibacterial agent used.

を形成するためである。When the adhesive force cannot be obtained between the outer layer and the inner layer, an adhesive resin is used. Any adhesive resin can be used as long as it has both the outer layer and the inner layer, for example, an acid-modified polyolefin resin or EVA resin. , Glycidyl group-containing resins, and the like. Further, a small amount of a different resin or other substance may be added to the resin layer for the purpose of improving the appearance. This is because the resin added in a small amount forms a so-called sea-island structure.
