BLOWN CONTAINER AND BLOW MOLD

摘要

A blow molded container of the present invention is a container formed by blow molding in which a single-layer or multi-layer parison comprising a cylindrical resin material is heated and inflated by air in a mold, wherein a bottom sealing portion formed by pinch offs of the mold has a projection projecting outwardly from the container and sunk portions formed in one of the resin layers constituting the projection such a manner as to be buried in the other resin layer. Therefore, the bonded area between the resin layers is widened, thereby having higher bond strength and higher strength against the shearing force along the fusion bonded area <IMAGE>
