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.

An easy-dispensing safety cap for selectively providing difficulty or ease in dispensing a liquid from a container comprising:

(a) an inner measuring means for measuring liquid to be dispensed from a container, the inner measuring means comprising a generally cylindrical configuration with one open end, an outer annular wall and an inner annular wall spaced from the outer annular wall and joined to the other annular wall by a bottom to define an upwardly opening measuring chamber within the outer annular wall, a planar surface extending across the inner annular wall to form a downwardly opening cavity within the inner annular wall which downwardly opening cavity provides means for engaging a container from which liquid is dispensed, a conduit extending through the planar surface for permitting fluid flow between the downwardly opening cavity and measuring chamber, means within the conduit for selectively permitting or preventing fluid flow therethrough and an outwardly extending lip on the outer annular wall having a notch therein;
and
(b) an outer cap comprising a generally cylindrical configuration formed by a sidewall with at least one opening extending through the sidewall, a top extending between the sidewall forming a downwardly opening cavity for receiving the inner measuring means such that the inner measuring means can slide within the cavity, stopping means positioned along the sidewall for engaging the lip on the outer annular wall of the inner measuring means and for preventing the inner measuring means from sliding out of the downwardly opening cavity, the inner measuring means being freely slidable between the stopping means and top, and a projection having a channel for fluid flow therealong extending downwardly from the top such that the projection engages the means within the conduit for permitting or preventing fluid flow through the conduit effectively closing or opening the conduit to fluid flow when the outer cap is rotated about the inner measuring means.
