Abstract

A fluid container spray device having a trigger lock mechanism with trigger tabs extending outwardly from the trigger and cleats extending inwardly from a moveable shroud. The cleats obstruct the tabs when the shroud is in a trigger lock position. A lever extending from beneath the shroud can be depressed, thereby moving the shroud from the trigger lock position to a trigger release position. The movement of the shroud to the trigger release position moves the connected cleats from their obstructive position to a position out of the trigger tabs' path of movement, thereby permitting use of the trigger to pump fluid from the container. The shroud is biased toward the trigger lock position. Thus, release of the container by the user restores the locked configuration, thereby preventing use by children.

First claim

The invention claimed is:

1. A spray device comprising:
(a) a trigger that is manually actuated to drive a pump that pumps a fluid from a container and dispenses the fluid from a nozzle connected to the pump;
(b) a shroud extending over at least a portion of the trigger, wherein the shroud is moveable relative to the trigger from a trigger lock position, in which movement of the trigger is obstructed, to a trigger release position, in which movement of the trigger is substantially unobstructed;
(c) a spring biasing the shroud into the trigger lock position; and
(d) means for moving the shroud against the spring from the trigger lock position to the trigger release position.

2. The improved spray device in accordance with claim 1 , wherein the spring further comprises at least one leaf spring extending from the shroud.

3. The improved spray device in accordance with claim 1 , wherein the spring comprises a pair of leaf springs extending from the shroud.

4. The improved spray device in accordance with claim 1 , further comprising at least one shroud-retaining tab protruding from the shroud.

5. The improved spray device in accordance with claim 1 , wherein the pump comprises a piston slidably mounted in a cylinder and the trigger has a trigger arm that extends to the piston.

6. A spray device comprising:
(a) a trigger that is manually actuated to drive a pump that pumps a fluid from a container and dispenses the fluid from a nozzle connected to the pump;
(b) a shroud enclosing at least a portion of the trigger, wherein the shroud is moveable relative to the trigger from a trigger lock position of the shroud, in which movement of the trigger is obstructed, to a trigger release position of the shroud, in which movement of the trigger is substantially unobstructed;
(c) a spring seated against the shroud and biasing the shroud into the trigger lock position; and
(d) a lever that is drivingly linked to the shroud for moving the shroud against the spring from the trigger lock position to the trigger release position.
