PURPOSE:To preserve stably for a long time a medicinal product or a food product without generating molds, etc., by making at least the innermost face of a plastic container anti-bacterial. CONSTITUTION:In a plastic container, the innermost face is constituted as an anti-bacterial innermost layer consisting of a layer forming material, an anti-bacterial substance, and pref. a carrier with the anti-bacterial substance. As the layer forming material, a thermoplatic resin such as polyolefin or polyester is used but no limination exists specially. In addition, as the anti-bacterial substance, a combination of one or two or more of heavy metals, pref. silver, copper, zinc is used and it is pref. that it is used under a carried condition on a carrier for stability during processing and preventing it from dissolving out from the layer forming material. As this carrier, no limitation particularly exists, but a zeolite solid particle, an active carbon particle, etc., are used. It is possible thereby to preserve a product for a long time without generating molds.
