摘要

PROBLEM TO BE SOLVED: To provide a cream-like substance pouring vessel comprising a vessel body and a cap-like member in which the cap-like member can be continuously used by exchanging the vessel body.;SOLUTION: This cream-like substance pouring vessel comp rises the vessel body 1 having an outwardly facing flange 4 on an upper part of a circumferential wall 3 with a circumferential wall part above the flange being a neck part 5 and the cap-like member 11 having a piston with a lower end cylindrical part thereof fitted to an outer surface of the neck part in an attachable/detachable manner. The member comprises a joint cylinder 12 which fits a cylindrical body 13 to the outer surface of the neck part in an attachable/detachable manner and erects a guide cylinder 15, a holding cylinder 21 which fits a lower part of the circumferential wall suspended from an outer circumference of a top plate into an upper part of the guide cylinder and suspends a connection cylinder 25 surrounding a pouring hole 24 opened in a center of the top plate, and a piston member 31 which fits a first elastic seal cylinder 35 protruded downwardly in the outer direction from the outer circumference to an upper inner surface of the neck part with the outwardly facing flange at the lower end of a pouring cylinder 32 fitted to and suspended from the connection cylinder as a cylindrical piston, and engages an upper surface of a second elastic seal cylinder 36 protruded upwardly in the outer direction with a lower surface of an inwardly facing flange 14.;COPYRIGHT: (C)2002,JPO
