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 manufacturing a pressure container including an in-mold label and a three-dimensional (3D) portion includes heating molds with a 3D groove formed therein to correspond to a 3D portion to be formed on a surface of the pressure container, separating the molds, attaching a label to an internal surface of the molds to allow at least a portion of the label to cover the 3D groove, positioning a pre-form of the pressure container in a cavity of the molds, closing the molds and injecting air into the pre-form at pressure in a specific range through a first route in a specific pressure range and expanding the pre-form, and three-dimensionally deforming a label attached to a surface of the pre-form to correspond to the 3D groove by air pressure along with the surface of the expanded pre-form while the expanded pre-form and the label are attached.

A transfer device with unrolling device, intended for providing a label handling system in an IML machine (In Mould Labelling) with IML labels. The transfer device comprises at least four holders, which are movable between a first and a second position, wherein the first position has a first predetermined relationship between the four or several holders regarding the distance in the X-direction. The holders are intended for retrieval of IML labels from the unrolling device, which comprises a label web, the length of which extends in the Y-direction, with partially stamped out labels, connected to the web with micro connections. The second position has a second predetermined relationship between the four or several holders regarding distance in the X-direction. The holders are intended to deliver the IML labels to the label handling system. The unrolling device comprises adjustment means to make possible the retrieval of labels in the Y-direction, so that the distance in the Y-direction between delivered labels has a different distance in the Y-direction than between two adjacent labels in the web. Further, a method of providing an IML machine with IML labels.

A method of manufacturing a composite container. The method includes providing a paper label, and a preform; providing a molding die equipped with a closed, cylindrical lower mold and an upper mold composed of a plurality of split-mold segments; arranging the paper label in the lower mold; arranging the preform between opened split-mold segments; moving one or both of the lower mold with the paper label and the upper mold with the preform in a direction towards each other to close the molding die; implementing blow-molding on the preform in the molding die; and opening the molding die to release the composite container.

A laminate including at least a heat-sensitive adhesive layer, a substrate layer, and a protective layer in this order, wherein the substrate layer has a thermoplastic resin film, the heat-sensitive adhesive layer contains a higher fatty acid amide, and the protective layer contains a silicone-based release agent. An in-mold label comprising this laminate. A molded body obtained by affixing this in-mold label. An in-mold label in the form of a roll obtained by winding this in-mold label. This invention provides an in-mold label that is less susceptible to dirt and scratches, excellent in decorativeness and visibility, less likely to cause friction when the labels are stacked on each other, and easy to handle, and has strong adhesive strength to a molded body.

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.

A blow-molded container includes a container body having a body portion that forms a square shape in a cross-sectional view orthogonal to a container axis; and in-mold labels, which are integrally glued on outer peripheral surfaces of glued portions, ranging from corner surfaces to respective planar portions continuing on both sides of corner surfaces around the container axis, in body portion. Among front and back surfaces of in-mold labels, multiple recesses are formed over entire back surfaces, which are glued to the outer peripheral surfaces of the glued portions. When tensile elasticity of in-mold labels is E (MPa) and thickness of in-mold labels is t (mm), Et.sup.3 is 0.20 or less.
