PURPOSE:To improve pollution removing performance and safety of the body of a push up type water storage coffee urn by preventing leakage of a coffee liquid in the extraction thereof. CONSTITUTION:A perforation hole 9a is provided at the center of the bottom of a basket 9 and a valve 30 is attached to the perforation 9a free to slide vertically through a spring 32. An O ring 31 is provided above a valve shaft 30a while an conical contact piece is below it. A protective wall 33 is erected below the bottom of the basket 9 approaching the outer circumference of the contact piece 30 and a guide rib is set toward the lower part of the outer circumference of the basket with the protective wall 33. When a decanter is attached or detached, a decanter lid is made to abut the contact piece 30b to make the valve 30 slide vertically. Thus, the coffee liquid can be dripped into the decanter or not by opening or closing the perforation 9a. |
