PROBLEM TO BE SOLVED: To costlessly realize a hygienic hermetically closable outpouring container in a simple constitution by welding a film-like member in which non- welding part is partly formed in the outpouring opening and using the non- welding part as the outpouring opening. SOLUTION: A film member 17 is heat-welded to the top face of a nozzle member 15 so as to cover a liquid passageway 16 of a nozzle body 14 fitted to the upper part of a container body 1. A non-welding part 18 is partly formed adjacently to the liquid passageway 16 by a method such as coating or printing of a resin having a high melting point in heat at the top face of the nozzle member 15. When depressing the nozzle body 14, a cylinder 10 slides down against the resilient force of a resilient body 9. In this time, a valve 13 is opened and the inner pressure is increased by the liquid discharged to the liquid passageway 16 of the nozzle member 15 from the inner hole 12 of the cylinder 10, and the film-like member 17 is elastically deformed and the outpouring opening 19 is opened and the liquid is discharged. |
