20100314281 | LAMINATED BOTTLE - A laminated bottle with a gas barrier resin layer arranged between polyester resins layers is provided. The gas barrier resin layer includes a plurality of quadrangular segments with two sides extending along the bottle axis and two sides extending around the bottle axis, wherein the segments are arranged at a distance to each other via connecting layers which connect the inner layer and the outer layer. | 12-16-2010 |
20110108505 | LAMINATED SYNTHETIC RESIN BOTTLE, INJECTION MOLDING DEVICE, AND PROCESS FOR MOLDING A LAMINATED PREFORM - A biaxially drawn, blow molded bottle characterized in that vertical connecting zones having no intermediate layer and having substrate layers welded directly with each other are formed in parallel in a circumferential direction and in a plural number along an axial direction of the bottle and are disposed on both right and left sides of each intermediate layer segment to be formed in this height range, and that horizontal connecting zones having no intermediate layer and having substrate layers welded directly with each other are also formed in parallel in an axial direction and in a plural number along a circumferential direction of the bottle and are disposed on both upper and lower sides of each intermediate layer segment to be formed, thus allowing the intermediate layer to be segmentalized in the circumferential and axial directions by both the vertical and horizontal connecting zones. | 05-12-2011 |
20140054255 | DEVICE FOR INJECTION MOLDING PREFORM, INJECTION MOLDING PROCESS, AND SYNTHETIC RESIN BOTTLE - Disclosed is an injection molding device and process for a test tube shaped preform, that can laminate a colored layer at certain positions with a certain thickness accurately. Included is a nozzle section, in which a molten main resin and second resin are joined together to form a joined resin mass, the nozzle section including: an outer flow channel through which the main resin flows, an inner flow channel through which the second resin flows, a cylindrical column-shaped flow channel where the second resin joins the main resin, a first confluence where the main resin flows into the joined flow channel, a second confluence where the second resin flows into the joined flow channel wherein the first confluence is downstream of the second confluence, and a cylindrical shutoff pin inserted in the joined flow channel to open or close one or both the first and second confluences. | 02-27-2014 |
20140091492 | LAMINATED SYNTHETIC RESIN BOTTLE, INJECTION MOLDING DEVICE, AND PROCESS FOR MOLDING A LAMINATED PREFORM - A problem to be solved by this invention is to control the above-described problem of delamination in the laminated and biaxially drawn, blow molded bottle. A major means of this invention to solve this problem is a biaxially drawn, blow molded bottle characterized in that vertical connecting zones having no intermediate layer and having substrate layers welded directly with each other are formed in parallel in a circumferential direction and in a plural number along an axial direction of the bottle and are disposed on both right and left sides of each intermediate layer segment to be formed in this height range, and that horizontal connecting zones having no intermediate layer and having substrate layers welded directly with each other are also formed in parallel in an axial direction and in a plural number along a circumferential direction of the bottle and are disposed on both upper and lower sides of each intermediate layer segment to be formed, thus allowing the intermediate layer to be segmentalized in the circumferential and axial directions by both the vertical and horizontal connecting zones. | 04-03-2014 |
20140287079 | DEVICE FOR INJECTION MOLDING A PREFORM - A preform-molding device has a nozzle section including three cylindrical layer-forming flow channels, which include an inner flow channel and an outer flow channel for forming the substrate layers of the main resin, and a middle flow channel for forming the intermediate layer, and also includes a predetermined number of vertical blocking rib pieces disposed at a downstream end of the middle flow channel, in parallel in the circumferential direction, so that the intermediate layer would be segmented in the circumferential direction into a predetermined number of vertically running streams, wherein flow behavior of the intermediate-layer resin flowing through the middle flow channel is adjusted by positioning the vertical blocking rib pieces in the circumferential direction so as to minimize a difference in height between a maximum height point and a minimum height point that appear in a leading edge of the intermediate layer of the preform. | 09-25-2014 |
20140327176 | PREFORM EXTRUSION MOLDING APPARATUS, METHOD FOR EXTRUSION MOLDING, AND PREFORM - A process includes: supplying a main resin from outer and inner flow channel, to a joined flow channel at a predetermined supply velocity for a predetermined time; supplying a second resin from a middle flow channel to the joined flow channel simultaneously with the main resin at a predetermined supply velocity for a certain time within the predetermined time; and sliding a shut-off pin to bring the pin forefront to a predetermined position near an outlet of the inner flow channel, open to the joined flow channel, before the second resin is supplied, or during a time starting after a time from the start of the second resin supply and ending with the termination of the supply, so that the velocity of main resin supply from the inner flow channel to the joined flow channel is reduced to a predetermined level by adjusting the degree of aperture for the outlet. | 11-06-2014 |
20150210420 | BIAXIAL STRETCH BLOW-MOLDED CONTAINER - A biaxially stretched, blow molded container is obtained by molding a laminated test tube shaped preform molded by an injection molding process. The container has a neck, a body, and a bottom, and having an outer shell and an inner bag to be laminated in a peelable manner with an outer layer inner surface. The inner bag can be deflated under a pressure drop therein. The outer layer and an inner layer have a laminar structure in which the lamination extends from a predetermined position of the neck to a lower end face. The layers are peeled from each other, starting from a lamination interface between the layers. This interface is exposed outside at the lower end face of the gate mark and can be used as an air intake vent that enables outside air to be taken into the space between the layers. | 07-30-2015 |
