Abstract

A water container cap including a push button for closing and opening a cap member is provided. A nipple disposed in the cap body is pulled up by the cap member when it is opened, by pushing the push button inward within a recess formed in the cap body. The nipple is connected with a soft flexible sucking tube fluidly communicating with the interior of a water container to which the cap is coupled. In this manner, the liquid stored in the water container may be withdrawn by sucking through the nipple.

Claims

1. A cap for coupling to a water container, comprising:

a cap body having a recessed chamber disposed therein, said cap body having a pair of first recess openings formed in opposing side walls of said recessed chamber;

fluid coupling means extending through a bottom wall of said recessed chamber of said cap body for providing fluid communication with a fluid disposed within said water container;

vent means extending through said bottom wall of said recessed chamber of said cap body for providing an inlet for air as fluid is displaced from said water container;

nipple means fluidly coupled to said fluid coupling means for withdrawing fluid from said water container therethrough, said nipple means includes (1) a nipple support member having a substantially U-shaped contour, and (2) a nipple member extending through a central portion of said nipple support member and having a longitudinally directed bore hole extending therethrough, said nipple member having opposing first and second ends, said second end being coupled to one end of a flexible conduit, said flexible conduit having an opposing end coupled to said fluid coupling means;

closure means pivotedly coupled to said cap body for providing access to said nipple member, said closure means including a longitudinally extended cap member having a pair of opposing transversely directed first projections being disposed at one end thereof, each of said pair of first projections being disposed in a respective one of said pair of first recess openings for pivotally coupling said cap member to said cap body, whereby said cap member is rotatably displaceable from a first position to a second position, said cap member forming a closure for said recessed chamber in said first position, said closure means further including a pair of arm members extending from a bottom surface of said cap member in spaced parallel relation, said nipple support member being pivotally coupled to said pair of arm members for displacing said nipple member from a position within said recessed chamber of said cap body responsive to said cap member being displaced to said second position, whereby said first end of said nipple member is accessible to a user for withdrawing fluid from said water container therethrough; and

,

a push button member slidingly coupled within an opening formed opposite said recessed chamber of said cap body, said push button member having an inverted U-shaped rod defining a through opening on an upper portion thereof for reversibly capturing a lug extending from an end portion of said cap member and in spaced parallel relation with said bottom surface thereof, thereby maintaining said cap member in said first position when said lug is captured by said push button member, said cap being free to be displaced to said second position responsive to said push button member being slidingly displaced into said opening sufficiently to disengage said lug from said through opening formed in said push button member.

2. The cap as recited in claim 1 where said push button member having a longitudinally directed post extending from a closed end of said button member for locating one end of a spring member thereon, an opposing end of said spring member being disposed contiguous a closed end of said opening for resiliently biasing said push button member in position for engagement with said lug of said cap member.
