Chemical dispenser safety hanger
First Claim
1. A hanger adapted to suspend a chemical dispenser from the rim of a tank, the hanger comprising an elongate sleeve integral with the dispenser, the sleeve having a restricted area proximate its top formed by opposed indented side wall segments that define a pair of shoulders with respect to the lower side walls of the sleeve, and a hanger member insertable within said sleeve, the hanger member comprising an elongate central portion having a plurality of side wall protrusions, a top portion extending rearwardly from the central portion and adapted to engage the rim of the tank, and a bottom portion forming opposed exterior shoulders with respect to the elongate central portion, the body of said bottom portion being substantially hollow such that the walls of the bottom portion are resilient below the shoulders, whereby the hanger member is inserted into said sleeve by engagement of said resilient bottom portion with said opposed indented side wall segments, which said bottom portion flexes due to its hollow nature and allows said opposed exterior shoulders to pass by said restricted area, said hanger member is adjustably positionable within the elongate sleeve by engagement of the protrusions between said indented wall segments, and whereby removal of the hanger member from the sleeve is substantially prevented by the hanger member shoulders abutting said sleeve shoulders.

Abstract
A hanger to adjustably suspend a chemical dispenser from the rim of a tank comprising a hanger member and a retaining sleeve therefore integral to the dispenser, the hanger member being positionable at discrete levels, which hanger member is substantially non-removable from the sleeve once inserted. A pair of shoulders in the hanger member cooperate with shoulders in the sleeve to prevent removal of the hanger member. Should the hanger member be removed, misuse is prevented by providing the hanger member with a resilient bottom portion that is substantially incapable of puncturing or prying open the chambers containing the chemicals to be dispensed. In a preferred embodiment, a second anti-removal means is provided in the hanger comprising a pyramidal indent in the sleeve and a ramp type stop member in the hanger member.

16. A hanger to suspend a chemical dispenser from the rim of a tank, the hanger comprising an elongate sleeve integral with the dispenser, the sleeve having a restricted area proximate the top in the shape of a funnel, a pyramidal indent being provided in the front wall thereof, with opposed shoulders being formed between the restricted area and the lower side walls of the sleeve, and a hanger member insertable within the elongate sleeve, said hanger member comprising a central portion in the form of a U-channel, the side walls thereof having a plurality of opposed horizontal, semicylindrical protrusions in spaced-apart relationship, the U-channel being further provided proximate its lower end with a ramp between its side walls, the base of said ramp adapted to engage the pyramidal indent;
- a top portion extending rearwardly from said U-channel, the top portion comprising a planar member substantially normal to the U-channel and a pair of substantially V-shaped members extending downwardly from the edge of the planar member distal the U-channel, said top portion being adapted for engagement of the rim of the tank, and a bottom portion that is a spade-like member, said spade-like member forming exterior shoulders at the sides of the U-channel, and having an ovate aperture therein to define resilient side walls of substantially uniform thickness below the larger semiaxis of the aperture, a compression relief slot extending upwardly from the top of the aperture into the rear wall of the U-channel, whereby the hanger member may be inserted into said sleeve by engagement of said resilient side walls with said opposed shoulders, which said resilient said walls flex and allow said resilient side walls to pass by said opposed shoulders, said hanger member is placed at the desired depth within the sleeve by engaging opposed protrusions between the side walls of the restricted area, and whereby removal of the hanger member is substantially prevented by the hanger member shoulders abutting the sleeve shoulders and the base of the ramp abutting the pyramidal indent.
