を見出すに至つた。 Conventionally, shears made of synthetic resin such as polycarbonate have been used, and when used, they are sterilized by boiling or are sterilized in advance and placed in a bag. In any case, there is the trouble of requiring sterilization treatment. put it here,
As a result of various studies on synthetic resin shear containers that do not require sterilization treatment, we found that the main bodies of the container and the lid shaped to fit the container are made of polypropylene, polycarbonate, and polyethylene, which are obtained by thermoforming a multilayered body by coextrusion. It has been found that a shear made of terephthalate or polystyrene and whose inner surface is at least made of a polyethylene layer is suitable.

きるので、無菌状態を維持することができる。 That is, when a multilayer body is manufactured by coextruding polypropylene, polycarbonate, polyethylene terephthalate, or polystyrene with low-density or high-density polyethylene, the melting temperature of these materials reaches 200 to 300°C, so the space between the layers becomes sterile. . The obtained multilayer sheet is formed into a desired shape of a shear container and lid by thermoforming such as air pressure forming or vacuum forming, but at least the polyethylene layer is placed on the inner surface of these sheets. Therefore, if necessary, a polyethylene layer may also be provided on the outer surface of the shear. When using the shear coat made in this manner, the polyethylene layer can be easily peeled off by hand, so that a sterile state can be maintained.
