CA 2393687

A hand holdable pump spray apparatus is disclosed where the pump mechanism is in the hand holdable wand (14) rather than in a spaced apart liquid container. The wand (14) may be held with one handle (54) is extended with other hand. This creates a pressure differential which allows liquid to flow from the container (10), passed a check valve (84) and into the wand (14). After filling, a biased spring provides a force against the liquid creating a higher pressure in the wand (14) than ambient pressure. This closes the check valve (84). When an operator depresses an actuator (68), another valve (88) opens allowing the liquid in the wand (14) to be ejected through a nozzle (66).

L'invention concerne un appareil portatif de vaporisation à pompe, dans lequel le mécanisme de pompe se situe dans le tube portatif (14) plutôt que dans un récipient liquide séparé. Le tube (14) peut être tenu d'une main tandis que l'autre main tend la poignée de la pompe (54), ce qui crée un différentiel de pression permettant au liquide de s'écouler du récipient (10), à travers un clapet (84) et dans le tube (14). Après remplissage, un ressort sollicité produit une force contre le liquide, créant ainsi, dans le tube (14), une pression plus élevée que la pression ambiante, qui ferme le clapet (84). Lorsqu'un utilisateur enfonce un actionneur (68), un autre clapet (88) s'ouvre, permettant au liquide du tube (14) d'être expulsé à travers une buse (66).
