PURPOSE: To make a material being dispensed from a container while the cap of a container stays at a fixed position by letting a plug means engage with an opening of a passage to form a seal against fluids, and forming the passage to allow free flow of the fluid from interior of the container to orifice when a cover means is open at the dispensing position. CONSTITUTION: An escape region 68 extends to the whole periphery of a plug 64 so as to allow it to be inserted smoothly into a dispense orifice 44 in order to make seal against the fluid in the passage 46 more perfect at the position where the closure is closed, namely a non-dispensing position, and further gives pliability to the plug 64. The length of the front wall 53 is determined so that it can completely cover the dispensing orifice 44 when closure is at the closed position. This is convenient for users to operate because the passage 46 opens by merely pushing up the edge portion 54 of the cover 48. The material can then be dispensed from the container 10 by tilting it and squeezing its both elastic sides. |
