In-mold labeled containers and molding process for production thereof

摘要

The invention relates to bringing a parison or a preform into contact with the body-molding surface of a split mold in such a way that the earliest contact of the parison or the preform with the molding surface occurs at a prescribed lengthwise position and thereby inhibiting the formation of air bubbles between the in-mold label and the container body formed from the parison or preform. In producing a container (1) comprising a body (4) and an in-mold label (7) covering the whole outer periphery of the body (4), a ring section (4a) having the minimum wall thickness which comes earliest into contact with the body-molding surface (14) of a split mold (13) is formed in the step of forming a parison or preform into the body (4) to inhibit the formation of air bubbles between the body (4) and the in-mold label (7) covering the whole outer periphery of the body (4).
