摘要： PROBLEM TO BE SOLVED: To provide a multi-layer container in which carbonated gas is prevented from being permeated, a thermoplastic resin layer is placed between an oxygen absorbing layer and a non-organic film layer while residual oxygen in the resin is being caught, the non organic film layer is not influenced by deterioration caused by catching oxygen of the oxygen absorbing layer, and a fragile characteristic in the non-organic film layer is restricted.
SOLUTION: A plastic multi-layer container is constituted by an inner layer 2 made of thermoplastic resin and an outer layer 4. An oxygen absorbing layer 3 is placed between the inner layer 2 and the outer layer 4, and the surfaces of the inner layer 2 and the outer layer 4 or the surface of the inner layer or the outer layer is provided with a non organic film layer 5.

摘要： PURPOSE: To prevent the heat creep phenomenon of a bottom part at a time of heating and sterilization by forming the bottom part of the molded body of a preform into a dome shape to form a secondary molded body and heating the bottom part and a part of the body part of the molded body by an infrared radiator to shrink the same and setting the bottom part to a size received in a semispherical plane to perform secondary blow molding. CONSTITUTION: The neck part of a preform is supported by a core mold 34 and a fluid is blown into the preform to form a secondary molded body 30. Next, the bottom part 38 and a part 39 of the body part of the secondary molded body 30 is heated by infrared heaters 42, 43 in a heat treatment process to obtain a tertiary molded body 40 wherein the bottom part 38 and a part 39 of the body part are shrunk. In this case, the bottom part 45 and a part 46 of the body part are set to a size wherein the trough bottom part of a final container is received in an imaginary semispherical plane 60 and formed into a shape relatively approaching the semispherical plane 60. Next, a fluid is blown into split molds 52 to perform secondary blow molding to form the bottom shape of the final container equipped with trough parts and foot parts by a bottom mold 5.

摘要： PURPOSE:To improve rigidity, heat resistance, dimensional stability, etc., by using polyester composition in which two types of thermoplastic polyesters containing different compositions are mixed at a special weight ratio, stretching to fix at least a body and crystallizing the opening, a bottom, etc. CONSTITUTION:This vessel is molded by using polyester resin in which thermoplastic polyester A containing ethylene terephthalate unit as a main ingredient and thermoplastic polyester B containing butylene terephthalate unit as a main ingredient are contained by weight of A:B=99.9:0.1 to 91:9. The vessel is formed, for example, with an opening (nozzle) 2, a conical trapezoidal shoulder 3, a cylindrical body 4 and a bottom 5 having a thick center 12. The opening 2 and the center 12 of the bottom are highly crystallized, and formed thicker than that of the body 4. The opening 2 and the bottom center 12 are so crystallized that a density crystallinity (XC) is 25% or more, and the body 4 is stretched to be thermally fixed.

摘要： PURPOSE:To provide a vessel with high strength being uniform in its film thickness and thin in its film. CONSTITUTION:By substantially high orientating without any restrictions the parts except a neck part and a heat-crystallized bottom central part, the vessel wall is orientation-crystallized and the vessel film is made thin and also the film thickness is rendered uniform, wherein with respect to the thickest film part except the neck part and bottom central part, the ratio of difference between the thickest film part and the thinnest film part is 50% or less and the yield value is made high and the strength is made high extremely. In this way, the quantity of resin used herein is decreased, thereby obtaining a vessel with high strength being light weight without whitening as well as being uniform in its wall thickness and thin in its film thickness.

摘要： PURPOSE:To obtain a thin-walled lightweight polyester bottle, the wall thickness of which is uniform and in which no whitening develops, by a method wherein the stretching of preform is performed by blow-stretching with pressurizing fluid under the substantially unrestrained state. CONSTITUTION:Most preferable highly stretching blow molding is to blow- molding 90% or more of the maximum radially stretched part of a bottle by pressurizing fluid, especially by high pressure fluid, under unrestrained state. Thus, by substantially unrestrained highly stretching blow-molding, a highly stretched bottle, the yield value in circumferential direction of the resin layer of the cylindrical part at the wall of a container of which is 2,000kg/cm or more and that in its direction of height of which is 800kg/cm or more, is produced. Accordingly, the shape of preform is preferably designed so as to blow- mold 90% or more of the maximum stretched part in its radial direction under its unrestrained state before it comes into tight contact with a blow mold.

摘要： PURPOSE:To obtain a container with a small age contraction and a large pressure resistant strength by a method wherein a fixed orientation property and crystallinity are given on the inner and outer surfaces of the body of a container which has a neck, body and closed bottom which are formed of a thermoplastic polyester by draw blow molding. CONSTITUTION:The title container is a container which has a neck, body and closed bottom which are formed of a thermoplastic polyester by drawn blow molding. The inner and outer surfaces of the said body have an orientation property which satisfies 1500>=n1>=1492 and 0.020>=n0-n1 =X1>=20% and 3%>=X1X0>0% (X0 shows the density method crystallinity index on the outer surface side of the body, and X1 shows the density method crystallinity index on the inner surface side of the body). By this method, a container, which has combination properties of a small age contraction and a large pressure resistant strength, and is suitable for a usage to fill carbonated beverages, can be obtained.

摘要： PURPOSE:To prepare a molded container reduced in shrinkage with the elapse of time and having high pressure-resistant strength by giving a specific temp. gradient to the inner and outer surfaces of a preform and effectively utilizing internal heat generation generated at the time of stretch blow molding. CONSTITUTION:A preform composed of thermoplastic polyester is heated so that inner surface temp. T1 and outer surface temp. T2 satisfy formulae T1>=85 deg.C, T0 =T0-T1>=0 deg.C and the heated preform is subjected to axial direction tensile stretching and peripheral direction expanding stretching in a hollow mold so that the stretching speed in the peripheral direction becomes 350%/sec or more and the stretching eccentric ratio D defined by formula (I) (wherein D1 is the area stretching ratio of the inner surface of the preform and D0 is the area stretching ratio of the outer surface of the preform) becomes 20-40%. By this method, a polyester container is prepared.
