Estimating the term…
A hygienic cap to close the opening of an inverted liquid container is provided for a liquid dispensing system for drinking water or other potable fluid. The cap has a lid portion to overlie and sealingly close the container opening and an annular skirt portion extending axially away from the lid to surround a portion of the container neck. The lid portion is provided with an axially inwardly extending recess including an outer sleeve and an inner plug portion integrally formed with a frangible connection therebetween. A feed tube is dimensioned for forcible insertion into the recess for breaking the frangible connection and separating the plug portion from the sleeve to permit the discharge of liquid from the container through the tube. When the tube is withdrawn from the recess, the plug portion is drawn into the sleeve to close the recess and reseal the container.
A hygienic cap for enclosing drinking water or other potable liquid within a substantially rigid liquid dispensing container during storage and transportation thereof, said container having a neck defining a discharge opening, said cap comprising, in combination, a lid portion adapted to overlie and sealingly close said discharge opening and an annular skirt portion extending axially away from said lid portion and adapted to surround an outer axial portion of said container neck, said lid portion having a one-piece axially inwardly extending recess formed therein including a first annular sleeve portion located generally centrally in said lid portion and integrally connected thereto and a second annular plug portion integrally connected to the inner end of said sleeve portion and extending axially inwardly therefrom, said plug portion having a closed inner end for normally closing said recess, said cap having means defining a frangible connection including an area of reduced wall thickness between said plug portion and said sleeve portion, said frangible connection being adapted to be ruptured and said plug portion axially separated from said sleeve portion upon the forcible insertion of a feed tube into said recess in order to permit the discharge of liquid from said container, and said plug portion being formed with an outside annular surface dimensioned to fit within said seal said sleeve portion when said feed tube is withdrawn from said recess.
