PUMP TYPE BUBBLE DELIVERING CONTAINER |
摘要 |
<P>PROBLEM TO BE SOLVED: To suppress or prevent any ringing attributable to the vibration of a valve part of a non-return valve caused by the flow of air to be fed from a pressurized air chamber to an air passage in a pump type bubble delivering container having the non-return valve consisting of a thin-walled annular valve part at an inlet of the air passage for communicating the air chamber with a mixing chamber. <P>SOLUTION: When the air chamber is pressurized, a fore end side of an inner valve part 16c of an elastic valve element 16 is elastically deformed upwardly. A stopper 72c which is brought into contact with an upper side of the fore end side of the inner valve part 16c while an inlet of the air passage D is opened by a predetermined amount to prevent any upward elastic deformation of the inner valve part 16c is provided on a lower surface side of an intermediate connection part 72 of an air piston 7 so as to be opposite to an upper surface on the fore end side of the inner valve part 16c of the elastic valve element 16. <P>COPYRIGHT: (C)2011,JPO&INPIT |
