Abstract
A hygienic liquid dispensing system is disclosed comprised of the combination of a container for the liquid to be dispensed, said container having a neck portion terminating in an aperture for discharging the liquid therethrough; a hygienic cap extending over said aperture and at least a portion of the neck to seal the liquid in the container; and a liquid dispenser, including a sleeve adapted to receive the capped container neck and a sharpened feed tube located within said sleeve for piercing said cap. The container with its capped neck is inverted and lowered into said sleeve and is guided thereby to position the cap over the feed tube. The hygienic cap has a recessed central portion and a relatively thin bottom portion (in said recess) which is pierced by the feed tube as the container is lowered into the sleeve. This piercing allows liquid to flow from the container to the dispenser. The feed tube, cap and sleeve arrangement is such as to insure a closely interfitting seal between the cap and the feed tube prior to the piercing of the cap bottom. This seal, among others that may be formed using the novel cap and dispenser combination, assures the hygienic dispensing of liquid from the inverted container. The dispenser sleeve also serves as a means for supporting the inverted liquid container.
