Abstract: A process for forming a container of acrylonitrile polymers by biaxial-orientation blow-molding a preform. A preform of thermoplastic resin, mainly acrylonitrile polymers, is irradiated with an electron beam or a gamma-ray. Immediately after the irradiation, the preform is heated at 40.degree. C. or higher to reduce residual acrylonitrile monomer in the preform to 0.1 ppm or less. Then, the preform is biaxial-orientation blow molded to form a container.

Abstract: An article of polyethylene terephthalate resin, particularly a laminated wall structure of a bottle made by biaxial orientation blow molding from the resin. The laminated wall is made up of polyethylene terephthalate resin and a synthetic resin material having good gas barrier properties.

Abstract: This invention relates to a saturated polyester bottle-shaped container and a method of fabricating the same from a material such as polyethylene terephthalate incorporating high transparency and superior mechanical surface strength. The hard coating is formed by the steps of coating an ultraviolet curable coating of methyl methacrylate resin on the surface of the body and irradiating ultraviolet rays over the surface of the body coated with the hard coating. Thus, the bottle-shaped container can largely enhance the wear resistance and extreme smoothness of the surface to eliminate dirt adherence onto the surface. In a second embodiment, an ultraviolet ray curable coating is coated onto the bottle, followed by a transparent resin coating which is cross linked with the ultraviolet ray curable coating.

Abstract: A hollow blow-molded bottle-shaped container of biaxially oriented resin mixture material comprising a polyethylene terephthalate resin and a xylylene group-containing polyamide resin, wherein the resin mixture material contains 5 to 30% of the xylylene group-containing polyamide resin to the polyethylene terephthalate resin. In this container, inner and outer surface layers of the container are formed of the polyethylene terephthalate resin, and the intermediate layer of the container is formed of the mixture resin material. In this manner, the gas barrier properties of the container can be enhanced.

Abstract: This invention relates to process for preparing saturated polyester resin bottles, that the residual strain of the bottles is reduced and the deforming temperature is elevated. The process is that a heated intermediate material (1) made of a saturated polyester resin is set in a mold (5), then compressed air is blown in the intermediate material (1) to orient the same biaxially, temperature in thus shaped bottle is elevated to a temperature higher than the heating temperature of the intermediate material (1) under the elevated pressure to effect thermal fixing and thereafter the saturated polyester resin bottle (19) is taken out.

Abstract: A collapsable tube of synthetic resin materials and adapted to prevent oxidization of the substance contained therein. The body of the tube is constructed of a laminated sheet which, in one embodiment, comprises a polyethylene film an oriented polypropylene film, a polyvinyl alcohol film and a polyethylene film in the order named. Due to the provision of the polyvinyl alcohol film the sheet has an extremely low permeability to oxygen gas and odour and is highly resistant to oil. The oriented polypropylene film provides for the sheet increased rigidity as well as improved printability. A non-return valve is provided at the tube orifice in order to prevent the entrance of air thereinto thus causing substantially no oxidization of the substance contained.

Abstract: A process for forming a collapsable tube having a flexible inner tube and a resilient outer tube. A shoulder member is formed having connecting surfaces. A flexible inner tube is joined to the shoulder member at a connecting surface. An outer tube encompassing the inner tube is joined to the shoulder member at a separate connecting surface so that the outer tube overlaps the joint between the inner tube and shoulder member. To resist permeation, the inner tube is formed by lap welding a laminated sheet of different natured materials and depositing a molten material along an edge of the sheet to seal it.
