Abstract
The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.
Claims10
A device to prevent crimping of a hose within a dispensing wand comprising:
- an elongated essentially hollow housing having a front and a back, the housing containing at least one deformable plastic tube in fluid connection with a pressurized source of reactants and a dispensing nozzle at the front;
- a pivotable forwardly-biased trigger attached to a bottom of the hollow housing, the trigger having a forward-extending projection, the trigger controlling a flow of fluid within the at least one deformable plastic tube by the interaction of a fixed v-shaped projection from the top of the housing and a movable projection at a top of the trigger;
- and
- a crimping minimization means positioned between the bottom of the hollow housing and a top surface of the forward-extending projection, the crimping minimization means prohibiting full forward extension of the trigger, the crimping minimization means maintaining at least a partial opening of the at least one plastic tube.

A device to prevent crimping of a pair of hoses within a dispensing wand comprising:
- an elongated essentially hollow housing having a front and a back, the housing containing a pair of deformable plastic tubes in fluid connection with a pressurized source of reactants and a dispensing nozzle at the front;
- a pivotable forwardly-biased trigger attached to a bottom of the hollow housing, the trigger having a forward-extending projection, the trigger controlling a flow of fluid within the pair of deformable plastic tubes by the interaction of a fixed v-shaped projection from the top of the housing and a movable projection at a top of the trigger;
- and
- a crimping minimization means positioned between the bottom of the hollow housing and a top surface of the forward-extending projection, the crimping minimization means prohibiting full forward extension of the trigger, the crimping minimization means maintaining at least a partial opening of the pair of plastic tubes.
