<p>PURPOSE: To easily suck and discharge contents such as liquid by a change in pressure at a bellowslike container part, in particular to fill liquid or the like without spilling by providing the bellowslike container part on an end of a hollow cylinder and providing a lid at an opening at the other end. CONSTITUTION: In use, while a bellowslike container part 1 is contracted, an opening 3 of a container is inserted into liquid or the like and then contraction of the part 1 is released, thereby sucking the liquid into a hollow cylinder 2 due to a negative pressure generated in the container part 1. Thus an operation for putting the liquid or the like into the container can be safely performed without spilling the liquid or the like. After the liquid or the like has been thus put in the container part 1, a lid 4 is put over the opening 3 to have the container closed. Then in taking out contents, the lid 4 is removed from the opening 3, and the bellowslike container part 1 is pressed, thereby discharging the liquid or the like put in the hollow cylinder 2 and the bellowslike container part 1 from the opening 3.</p> |
