ABSTRACT:
An easy-dispensing safety cap for selectively providing difficulty or ease in dispensing liquid from a flexible wall container is disclosed. The easy-dispensing safety cap comprises two nested cylindrical configurations: an inner cap and an outer cap. The inner cap has an outer annular wall and an inner annular wall spaced from the outer annular wall and joined to the outer annular wall by a bottom. A planar surface extends across and joins the inner annular wall defining a downwardly opening cavity. The downwardly opening cavity can be fitted over a neck of a flexible wall container. A conduit extends through the planar surface for permitting liquid flow between the downwardly opening cavity and a measuring chamber defined by the outer annular wall. A disk having an opening is fitted within the conduit. A lip having a notch thereon extends around and projects outwardly from the annular wall. The inner cap is nested within the outer cap. The outer cap comprises a cylindrical figure having a sidewall. A top extends across and joins the sidewall forming a downwardly opening cavity. At least one opening is provided through the sidewall. A projection having a channel therealong is attached to the top and extends downwardly into the cavity and into the conduit engaging the disk for selectively plugging or opening the conduit to fluid flow. A detent is on the inner surface of the sidewall. The detent catches on or engages the lip on the inner cap for preventing the outer cap from being lifted off the inner cap. The outer cap can rotate about the inner cap and can slide up or down until the detent on the sidewall catches the lip on the inner cap.
