Fitting for emptying a container

Abstract

A fitting for dispensing liquid from a container, including a housing for mounting within an opening of the container, a one-way valve within the housing for allowing liquid to only flow outward from the container, and a first drain hole through the housing wall. One of two selected tubes is inserted into the bottom open end of the housing: either a first tube with a solid cylindrical wall blocking the first drain hole, with a telescoping dip tube attached, or a second tube with a second drain hole through its cylindrical wall for alignment with the first drain hole. When the first tube is selected, liquid may be pumped from the container. When the second tube is selected, the container may be inverted and liquid may empty by gravity. The first and second drain holes allow residual liquid to be drained from within the container. A tamper evident wire seal may attach the housing to the container, preventing removal therefrom. A cap, attached by a strap to the housing, can seal the outer opening of the housing. The dip tube attached to the first tube may be of various lengths or diameters.
