<P>PROBLEM TO BE SOLVED: To prevent dripping of pressurized content from a discharging port through an original discharging passage while opening an upper valve and a lower valve when air in the container which has expanded by the change of the environmental temperature pressurizes the content in a pump type product. <P>SOLUTION: For this pump container, a hole section 6a which makes the inside of the container always communicate with the external space is formed at the top surface section 6 of the container body. Therefore, the air in the container which has expanded by the change of the environmental temperature flows out to the external space through the hole section, and no dripping of the content from the discharging port 1b is caused by the pressurization of the content. Additionally, in the circulation phase of the product, the hole section is closed by a chip-form member 11 for the initial closing, and no dripping of the content from the hole section is caused. <P>COPYRIGHT: (C)2008,JPO&INPIT |
