The objects of this invention are to set a predetermined height position for the portion of parison or preform that is the first to come in contact with body molding planes of a split mold and to prevent air from being trapped between in-mold labels and the container which is blow molded from the parison or the preform. In-mold labels are fixed to the entire outer surface of body of main container. An annular thinnest wall portion is formed in the wall of the body so that the thinnest wall portion is the first to come in contact with the body molding planes of a split mold. Under this construction, no bulge of air is formed between the body and the in-mold labels fixed to the entire surface of the body.

A technical problem of this invention is to create in-mold labels that can be adhered to wide areas, including 3D curved areas, of the peripheral wall of a synthetic resin container in a high-grade state without air entrapment and/or wrinkling. A principal means of this invention to solve the technical problem described above is in-mold labels used as an inserted material and adhered to the outer peripheral wall of a container main-body concurrently when the main body is being molded, said labels including an adhesive layer to be adhered to the outer peripheral wall of the container main-body, wherein this adhesive layer has depressed portions on a back surface thereof, the depressed portions being formed by embossing and being disposed in a regular pattern.

Disclosed are a valve device and a blow molding system. The valve device is applied to a blow mold and one or two decorative leathers for affixing to a bottle body is/are placed in the blow mold. The valve device comprises a base and at least one pintle arranged on the base, with one pintle being inserted into a vacuum suction hole of the blow mold. The valve device opens the vacuum suction holes to create negative pressure and enable decorative leather to be adsorbed to the inner wall of the blow mold, and blocks the vacuum suction holes to achieve detachment between the decorative leather and the inner wall of the blow mold, to adhere the decorative leather to the bottle body to complete the production.

A method of forming a blow molded plastic article wherein the article comprises an airflow conduit, comprising: providing a first sheet of insulation material located on a insulation carrier; providing a blow molding mold including two halves and having a molding surface defining a molding cavity to form the article; locating the insulation carrier between the two halves of the blow molding mold; transferring the first sheet of insulation material from the insulation carrier to the blow molding mold; introducing an extrudate of thermoplastic composition between the two halves of the blow molding mold; closing the blow molding mold; forming the extrudate to a shape of the mold cavity of the blow molding mold to form the article; and bonding the extrudate to the first sheet of insulation material as the extrudate is being formed to the shape of the mold cavity.

The present invention provides a labeled blow-molded container having a convex portion and/or a concave portion on a label face, and a blow molding mold. The labeled blow-molded container of the present invention including a blow-molded container containing a thermoplastic resin; and a label containing a thermoplastic resin film, the labeled blow-molded container being formed by the blow-molded container being thermally fused to a label; a label face of the container to which the label is affixed having a convex portion and/or a concave portion; and a height difference (h) representing a distance between the highest part of the label surface and the lowest part of the label surface being not less than 0.3 mm using the label face as a reference in a height direction.
