Water bottle with a hidden suction straw

Claim 1

A water bottle comprising: a container with an upper open end; a cap comprising a skirt portion for releasably engaging with the upper open end of the container, a neck portion, and a circular head plate which has a diameter greater than that of the neck portion thereby defining an annular groove around the neck portion, the head plate having an outer side and an inner side and at least one cut edge, an arcuate stop projecting from the outer side of the head plate, a second neck being formed on the outer side of the head plate, first and second holes being formed in the head plate in an area defined by the second neck and communicating with an inner space defined by the container; a suction head member including a collar which is rotatably received in the second neck and a substantially L-shaped suction straw which has a lower end securely engaged with the collar, the collar including an opening and a recess in an underside thereof, a second cap being mounted around the second neck for restraining the collar in the second neck and having an opening through which the suction straw passes; and a cover including a plurality of protrusions on an inner surface thereof for engaging with the annular groove around the neck portion of the cap, a second opening being formed in the cover and a tongue extending downwardly from the inner surface of the cover, two spaced stop pieces being formed in the inner surface of the cover, the cover being rotatable between first and second positions; wherein when the cover is in the first position, the arcuate stop blocks the second opening in the cover to hide the suction straw and one of the stop pieces contacts with the arcuate stop to prevent rotation of the cover in one direction, while the first opening in the collar does not align with the first hole and the recess in the collar does not align with the second hole, when the cover is rotated along a direction opposite to the first mentioned direction to the second position, the tongue contacts and thus actuates the suction straw to rotate such that a distal suction end of the suction straw extends beyond the second opening in the cover until the other stop piece is stopped by the arcuate stop at the second position where the first opening in the collar aligns with the first hole and the recess in the collar aligns with the second hole.
