Disclosed is a method of treatment with a microwave plasma by maintaining a reduced pressure in a plasma-treating chamber for treatment with a plasma in which a substrate that is to be treated with a microwave plasma is contained, introducing a treating gas into the plasma-treating chamber and introducing microwaves into the plasma-treating chamber, wherein a metallic antenna is disposed in the plasma-treating chamber. The plasma is generated within a very short period of time maintaining stability after the microwaves are introduced into the plasma-treating chamber, and the treatment is accomplished maintaining stability.

The present invention relates to manufacture of container product with a constant level of quality, wherein the performance is constant, by resolving problems including transformation of perform performance caused by the temperature variation of the preform; or by the variation in the stretching blow molding due to a thermal difference between the surface and the inner part of the preform, resulting from the thickness thereof, in order to industrialize a new molding method recognized to be an excellent molding method from the point of view of economic efficiency and production efficiency, wherein compression molding and stretch blow molding are performed continuously. By a method or device for manufacturing continuously synthetic resin containers, preforms are molded by compression with a compression molding machine, then stretch blow molding is performed with a stretch blow molding machine. After discharging molded preforms from the compression molding machine, an even-heating treatment of preforms, a partial heating or partial cooling treatment according to need and then stretch blow molding are performed.

An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure 10 includes the steps of: compressing and deforming the multilayer structure, while extending respective layers 11, 12, 13 of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter 15, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion 14, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer 11 and surface resin layers 12, 13 of the multilayer structure to the abutting portion A of the push cutter 15 and the cutter receiving portion 14.

A pouring mouth member (1) for a container (T) includes an intermediate resin layer (8) having barrier property and a fold-back portion (9) is formed on at least one end portion of the intermediate resin layer (8) having barrier property. Further, due to an inner layer resin (6) and/or an outer layer resin (7) provided to an outer periphery of this fold-back portion (9), the exposure of the resin (8) having barrier property can be surely prevented and, at the same time, a cut edge of the intermediate resin layer (8) having barrier property is effectively sealed between the inner and outer layer resins (6,7) since the cut edge is also in a fold-back state.

The present invention herein provides an oxygen-absorbing resin composition which is excellent in the oxygen-absorbability and which can inhibit any deterioration through oxidation during the molding operations of the composition and does not accordingly undergo any coloration during the molding operations. The present invention thus provides an oxygen-absorbing resin composition characterized in that it comprises (A) a hydrogenated styrene-diene copolymer; (B) a thermoplastic resin including ethylenic structural units in its molecular structure; and (C) a transition metal catalyst, wherein the oxidation of the thermoplastic resin (B) proceeds while the copolymer (A) serves as a trigger and the composition thus absorbs oxygen. In this respect, the copolymer (A) comprises carbon-carbon double bonds derived from the diene in an amount ranging from 1 × 10 -5 to 1 × 10 -2 eq/g.
