| 20090104392 | Synthetic resin containers with high barrier property - There is provided, in a simple manner, a synthetic resin container which improves a vapor barrier property while maintaining a gas barrier property against oxygen or the like at a high level. The present invention is a PET bottle having a barrier film | 04-23-2009 |
| 20090022964 | Molded Resin Product and Process for Surface Treatment Thereof - An object of this invention is to provide a molded resin product having atmosphere of a quality product as a result of a stereoscopic pattern that is formed on the container surfaces by a simple method such as coating or vapor deposition. Another object of this invention is to provide a surface treatment process for laying a stereoscopic pattern of high quality on the resin surfaces. The molded resin product of this invention comprises a substrate made of a transparent resin, opaque coating film disposed on rear surface of the substrate except for an area set aside for a patterned portion, a transparent resin material disposed in the area set aside for the patterned portion on the rear surface of the substrate, and an opaque reflection coating or a half-reflective coating laminated to the transparent resin material. Under this configuration of the molded resin product of this invention, the patterned portion looks as if it pops up from the rear surface of the substrate. If a half-reflective coating is used, the pattern is visible through the half-reflective coating when the pattern is viewed from the rear surface of the lid of a molded resin product, thus giving atmosphere of high quality to the container. | 01-22-2009 |
| 20090020497 | Bottle - The bottle is provided with a base portion installed on the outer circumference brim of the bottom, a central recess installed inside the base portion and recessed toward the inside of the bottle, an annular wall portion installed between the base portion and the central recess and inclined so as to elevate gradually from the base portion to the central recess, and a plurality of ribs installed side by side at the annular wall portion in the circumferential direction of the bottom and protruding toward the inside of the bottle. The ribs are provided with a rising wall portion rising toward the inside of the bottle and an inclined wall portion inclined from the upper brim of the rising wall portion toward the lower brim of the rising wall portion of an adjacent rib. The rising wall portion is inclined more steeply than the inclined wall portion. | 01-22-2009 |
| 20090011165 | Transfer Film - The technical problem to be solved by this invention is to eliminate the release layer from the transfer film. The object of this invention is to provide a transfer film that can be applied stably to the transfer process without any trouble. The transfer film of this invention comprises a substrate to be peeled off during the transfer process and a transferred layer to be transferred to an article to be decorated, both of which are laminated directly to each other in a peelable manner by an extrusion laminating process without requiring any release layer. | 01-08-2009 |
| 20080317989 | Synthetic Resin Bottle Having a Gradation Pattern, and Process for Injection Molding the Preform for Use in Such a Bottle - The technical problem to be solved by the invention is to change the thickness of the colored resin layer of the preform gradually in the upward or downward direction, by utilizing a tendency of gradual decrease in the thickness of the colored resin layer caused by the flow of the main resin inside the preform mold when the main resin and the colored resin are injected into the mold. The objects of this invention is to provide a biaxially drawn, blow molded bottle having new decorativeness created in which sophisticated color gradations associated with color density are created in the body of this bottle. The means of accomplishing this object involves adjusting the injection pattern including the time of starting and ending the supply of the main resin and the colored resin, and pressure or velocity profiles, reducing the thickness of the colored resin layer in the multi-layered molten resin fluid gradually at an upstream or downstream point of the flow, injection-molding the preform in which a color-gradated portion associated with the thickness of the colored resin layer has been formed, and biaxially drawing and blow molding this preform into a bottle having a color-gradated portion associated with the color density or color shade created on the body of the bottle. | 12-25-2008 |
