| 20090061132 | CONTAINER FORMED BY STRETCH FORMING AND PROCESS FOR PRODUCING THE SAME - A stretch-formed container having a layer comprising a blend of an ethylene terephthalate type polyester resin and another material, characterized in that the layer comprising the blend has a dispersion structure composed of a continuous phase comprising the ethylene terephthalate type polyester resin and a dispersed phase comprising the other material and that at least the container body part has a tan δ maximum temperature of 115° C. or lower in a dynamic viscoelasticity examination. Due to the constitution, even when the mechanical stretching rate reaches a limit, strain hardening effectively occurs. Thus, a stretch-formed container of a polyester resin can be provided which has both of excellent heat resistance attributable to high-temperature stretching and a stretch balance attributable to strain hardening. | 03-05-2009 |
| 20100092621 | MULTI-LAYER PLASTIC CONTAINER FOR NON-OILY CONTENTS - [Problem] To provide a polyethylene container which enables a non-oily viscous content such as ketchup or the like to favorably run down when the container is inverted. | 04-15-2010 |
| 20100116707 | PRESSURE-RESISTANT POLYESTER CONTAINER AND PROCESS FOR PRODUCING THE SAME - A pressure-resistant polyester container having a multilayer structure comprising inner and outer layers of a polyester resin and at least one intermediate layer of a functional resin, wherein in the container body portion, the inner layer of the polyester resin has a crystallinity of not less than 23%, the outer layer thereof has a crystallinity of not less than 18%, the average value of the crystallinity of the inner layer and the crystallinity of the outer layer is not less than 24%. The pressure-resistant polyester container effectively prevents whitening even after the passage of time and features excellent transparency despite of using, as an intermediate layer, a functional resin composition obtained by blending a functional resin with a clay. The invention, further, provides a process for producing the same. | 05-13-2010 |
| 20100129577 | MULTI-LAYER POLYESTER CONTAINER AND METHOD OF PRODUCING THE SAME - A multi-layer polyester container comprising inner and outer layers of a polyester resin and at least one intermediate layer of a functional resin or a functional resin composition, wherein a difference of tan δ of the inner polyester layer at 80° C. and 60° C. is 0.035 or less in the measurement of the dynamic viscoelasticity (DMS) thereof at 0.5 Hz. Even when the functional resin or the functional resin composition having a large draw stress is used as an intermediate layer, therefore, excellent transparency is obtained while effectively exhibiting the function such as barrier property possessed by the functional resin or the functional resin composition. | 05-27-2010 |
| 20100136271 | MULTILAYERED CONTAINER - Disclosed is a multilayered container having an intermediate layer comprising an oxygen-absorbable barrier resin composition showing excellent processability upon molding. Specifically disclosed is a multilayered container which comprises an inner layer and an outer layer each comprising an olefin resin and an intermediate layer provided between the inner layer and the outer layer and comprising an oxygen-absorbable barrier resin composition, wherein the oxygen-absorbable barrier resin composition has a cooling crystallization peak temperature lower than that of a base resin (an oxygen barrier resin) which constitutes the oxygen-absorbable barrier resin composition, the multilayered container is formed by a solid-phase forming process at a temperature lower by 1 to 15° C. than the cooling crystallization starting temperature (Tc2) of the base resin, and the body of the container shows a calorific value of less than 0.5 J/g by the isothermal crystallization after heating from 30° C. to 130° C. at a heating rate of 100° C./min in a thermal analysis of the body. | 06-03-2010 |
| 20100206762 | MULTILAYER POLYESTER CONTAINER AND PROCESS FOR PRODUCING THE SAME - A multilayer polyester container comprising inner and outer layers of a polyester resin and at least one intermediate layer of a polyamide resin, wherein in the container body portion, the intermediate layer of the polyamide resin has an exothermic peak starting temperature due to crystallization of not lower than 96° C. as measured by a differential scanning calorimetry, and a clay is dispersed in the polyamide resin, effectively preventing whitening of the intermediate layer even after the passage of time and featuring excellent transparency despite of using, as an intermediate layer, a polyamide resin composition obtained by blending the polyamide resin with the clay. | 08-19-2010 |
| 20100323140 | MULTILAYERED CONTAINER EXCELLENT IN OXYGEN-BARRIER PROPERTY - A multilayered container with excellent heat resistance which is obtained by melt molding and has an interlayer made of an oxygen-absorbing barrier resin composition. The multilayered container comprises inner and outer layers comprising an olefin resin and, sandwiched between the inner and outer layers, an interlayer made of an oxygen-absorbing barrier resin composition. The multilayered container is one formed by melt molding. In thermal analysis of a container barrel part, it has a quantity of heat of isothermal crystallization after heating from 30° C. to 130° C. at 100° C./min of 0.5 J/g or larger. In the analysis, the barrel part, after cooling from 200° C. to 130° C. at 100° C./min, gives an isothermal crystallization profile in which the time period to a peak top is shorter than that in a multilayered container including an interlayer consisting only of the base resin (oxygen-barrier resin) constituting the oxygen-absorbing barrier resin composition. | 12-23-2010 |
