The present invention provides a moisture-absorbing resin composition comprising resin (A) in an amount of 100 parts by mass, and zeolite in an amount of 40 to 300 parts by mass, wherein resin (A) contains at least one polymer selected from among ethylene-methyl acrylate copolymer, ethylene-ethyl acrylate copolymer, ethylene-butyl acrylate copolymer, copolymer of ethylene-ethyl acrylate and acrylonitrile-styrene, and copolymer of ethylene-ethyl acrylate, maleic anhydride, and acrylonitrile-styrene, and a molded product produced through molding of the moisture-absorbing resin composition. The moisture-absorbing resin composition exhibits high moisture absorbency, high moisture absorption rate, and adhesion, and the molded product is produced from the composition.

An improved synthetic resin spout stopper to be combined with a discharge port of a container is provided. The spout stopper does not pose difficulty in breaking an annular score formed in an annular flange wall, when discarding the container. Damage to the annular score is avoided even if a considerably great impact is applied to the spout stopper owing to a fall of the container. Damage to the annular score is also avoided even when ultrasonic welding is adopted for welding the container and the spout stopper together. In an inner peripheral edge part of the annular flange wall, an annular additional score is disposed adjacent to the annular score radially outwardly of and/or radially inwardly of the annular score.

A liner material supply apparatus by which the weight ratio between a first feedstock liquid and a second feedstock liquid to be fed to static mixers () is maintained sufficiently precisely. A heater for bring the temperature of the first feedstock liquid, which is fed from a first accommodation tank () to the static mixers through a first feeding pump (), and the temperature of the second feedstock liquid, which is fed from a second accommodation tank () to the static mixers through a second feeding pump (), to predetermined temperatures are annexed, at least, to the first feeding pump and the second feeding pump. Liner material acceptance unit () is disposed which is selectively located at an operating position where the liner material acceptance unit accepts a liner material discharged from discharge unit (), and a non-operating position where the liner material acceptance unit does not interfere with the liner material discharged from the discharge unit.
