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 clam shell type container having an injection moulded base, an injection moulded lid, and a web interconnecting the base and lid, wherein the web is formed from an in-mould label. The in-mould label is preferably deposited into a mould that simultaneously forms the base and lid, with the label being deposited into the mould prior to the injection of molten material. Upon formation, the label extends contiguously into the base and lid and becomes integrally adhered with the walls of the base and lid.

When a molten plastic is molded using a metal mold, sufficient cooling time has to elapse before the metal mold is opened, but this cooling time restricts the production per unit time. If a metal mold is opened without sufficient cooling, the plastic undergoes significant deformation by thermal shrink. If this deformation can be estimated and the metal mold designed so as to make allowance for the anticipated deformation, it will be possible to produce a molding with a shape that is equal to the design dimensions, despite shortening the cooling time. The finite element method is used to obtain the deformation. Mold design can also be performed taking account of the deformation due to the hydrostatic pressure that is produced when the molding is filled with its liquid contents. In addition, as for a portion of an in-mold labelled container which include lamination construction, the deformation due to thermal shrink is not estimated as a container which an in-mold label is not being applied. On this case, we have a method which is simulating deformation after adding parameters relating to the material of this label, said parameters including at least its thermal conductivity and coefficient of linear expansion. The thermal conductivity deformation simulation is by the finite element method. Production per unit time can be increased and metal mold design can be carried out independently of experience.

A bottom rim is disposed in the lower part of the inmold labeled type plastic container, with its dimension being not less than 0.3 mm but not more than 20 mm, and the inmold labeled type plastic container to be provided is labeled on its bottom rim in a similar way to the side part of the container.

The invention relates to an in-mold labeling method, and to molded plastic articles having an in-mold label as described herein. In one embodiment of the invention, the in-mold label film comprises: (A) a polymer facestock having a printable upper surface and a lower surface, (B) a print layer having an upper surface and a lower surface wherein the lower surface of the print layer is in contact with and adhered to the upper surface of the facestock, and (C) an adhesive layer having an upper surface and a lower surface wherein the lower surface is in contact with and adhered to the upper surface of the print layer.

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 7 are fixed to the entire outer surface of body 4 of main container 1. An annular thinnest wall portion 4a is formed in the wall of the body 4 so that the thinnest wall portion 4a is the first to come in contact with the body molding planes 14 of a split mold 13. Under this construction, no bulge of air is formed between the body 4 and the in-mold labels 7 fixed to the entire surface of the body 4.

A drawer cart with in-mold labels includes a cart and a plurality of drawers made by injection molding. Each drawer has a housing compartment opened upward and a display surface. The drawers are slidably mounted onto the cart with the display surfaces exposed outwards and can be partially drawn away from the cart to expose the housing compartment. The display surface contains an in-mold label formed during the injection molding. The in-mold label has patterns for indication and visual aesthetic, and also facilitating classification of goods held in the drawers. The patterns on the in-mold label can be designed differently in response to varying display surfaces and can be combined to form a whole pattern to enhance total design sense and meet use requirements.

This invention relates to a 3-layer co-extruded biaxial-oriented pearly synthetic paper label used for integrally molding with bottle in mold; more particularly, it relates to a manufacturing equipment and method of said 3-layer co-extruded biaxial-oriented pearly synthetic paper label. The pearly synthetic paper label produced by the manufacturing method of this invention has a 3-layer structure which is layer-laminated with a printing paper surface layer, a foamed intermediate layer, and an in-mold label-adhered layer; the pearly synthetic paper label can be applied in the blow-mold or eject-mold of polypropylene(PP) bottle or of high density poyethylene(HDPE) bottle, in which the pearly synthetic paper label is integrally molded by heat adhesion with the PP bottle or HDPE bottle under being molded in the mold; meanwhile, the abnormal situation like encapsulated air bubbles is prevented from happening so as to make the PP (or HDPE) bottle which is integrally molded with label have an excellent appearance and quality. The main process of the manufacturing method of this invention is: various compositions which represent the printing paper surface layer, the foamed intermediate layer, and the in-mold label-adhered layer respectively are co-extruded, by using two secondary extruders and one primary extruder, through one T-type die to form a 3-layer resin composition; then, through procedures of cooling/forming, biaxial orientation, corona discharge treatment, and laminating/rolling, a 3-layer co-extruded biaxial-oriented pearly synthetic paper label used for integrally molding with bottle in mold is obtained. This invention, of which the manufacturing process is simple and the cost is low, completely breaks through and fully improves the complicated process of conventional methods wherein the plastic film or a synthetic paper is either coated with a heat-melted adhesive or fabricated to be an in-mold label-adhered layer after being embossed; thus, this invention is of industrial applicability to the PP bottle or the HDPE bottle manufacturing industry.
