초록 ▼

A straw for a drinking container that is self-ventilating and self-sealing. The straw has two parts, a straw tip and a straw cover. The cover is retained on the straw tip and is movable by manual pressure between a closed position and an open position. The tip has a solid closed top and an open bottom to allow for a straw extension piece to extend into the container for drawing liquid up into the straw. The straw is self-sealing in that a hole in the cover through which a user would suck is sized to sealingly fit the end of the tip in the closed position. In addition, the cover and tip are sealed at the open bottom in the closed position and drainage holes in the tip allow any liquid that falls between the cover and the tip to flow back into the container. The tip has an abutment surface around its perimeter between holes that release liquid in the user\s mouth and holes that allow for air intake. The straw is self ventilating in that when the cover, which is attached to the tip just above the abutment surface, is moved to the open position, ridges on the inner surface of the cover grasp the tip\s surface at certain points so as to automatically allow air into the container to draw out liquid, while at the same time preventing air from entering the user\s mouth.

대표청구항 ▼

A straw for a drinking container comprising: (i) a tip having an internal channel terminating at a solid closed top and an open bottom and at least one first hole for liquid egress through the side of the tip into the channel and having at least one second hole through the side of the tip into the channel for air intake lower than the first hole; (ii) an abutment surface of the tip around the outside of the perimeter of the tip between the first hole and the second hole; (iii) a hollow cover movably retained on the tip and surrounding the tip having a hole at its upper end sized to fit around the solid top of the tip in sealing engagement when in a first closed position and in disengagement when in a second opened position so as to allow liquid to be removed in such second position; (iv) a first ridge on an inner surface of the cover which is sized to sealingly engage the abutment surface between the first and the second hole when in the second open position; and (v) a second ridge on an inner surface of the cover below the first ridge which is sized to sealingly engage the tip below the second hole when in the first closed position and which disengages from the tip when in the second open position so as to allow air into the second hole in such second position.
