Definitions

  • This invention relates to actuators for hand operated dispensing pumps and more particularly, to actuators for hand operated dispensing pumps that foam the fluid being dispensed without the use of aerosol propellants.
  • Hand operated foam pump dispensers are well known in the personal care industry for dispensing foam products. Pumps of this type require that the liquid and air be mixed under pressure in a dispenser bottle.
  • Hand operated foam pumps commonly include a liquid pump chamber and an air pump chamber. Typically, a piston moves between the charge and discharge positions in the air pump chamber and the liquid pump chamber to draw air or liquid into the respective chambers and force the air or the liquid from the chambers into a mixing region where the mixed air and liquid produce foam and the foamed products subsequently exit the nozzle of the actuator.
  • Prior art hand operated foam pumps are typically operated by means of trigger action requiring a trigger handle or linear action requiring a push button actuator. Both types of mechanisms feature fixed nozzles that protrude from the sides of the actuators.
  • the present invention provides a new design for an actuator assembly for a hand operated foam pump.
  • the new actuator assembly comprises an actuator, a folding nozzle and a pump closure.
  • the folding nozzle of the new actuator assembly eliminates the protrusion of a conventional nozzle or trigger handle and thereby helps to prevent the closure of the actuator assembly from loosening and unlocking during shipping.
  • the folding nozzle of the actuator assembly of the present invention is configured so as to lock the actuator in place and prevent operation of the hand pump when the nozzle is folded.
  • the folding nozzle of the actuator assembly substantially reduces pump closure loosening, i.e. the tendency of the closure to loosen or separate (i.e. back-off) from the dispenser bottle due to vibration during shipping.
  • the folding nozzle substantially reduces the likelihood of parts breakage during shipping of a filled product, again by eliminating trigger handles or other conventional nozzle types which protrude from the side of the actuator.
  • the ability of the actuator assembly of the present invention to resist loosening and unlocking during shipping is further enhanced by configuring the folding nozzle such that it is locked to the actuator via snap tabs when in the folded position. The folding nozzle is unfolded after the package is delivered and ready for use.
  • the ability of the actuator assembly of the present invention to resist loosening and unlocking during shipping is further enhanced by providing an actuator assembly that is free of any sharp edges, surface discontinuities or protrusions that may catch on other containers or packaging during shipping.

Abstract

La présente invention concerne un actionneur pour une pompe de distribution de mousse actionnée manuellement qui utilise une buse pliante. La buse pliante de l'actionneur est configurée de façon à bloquer l'actionneur en place et à empêcher le fonctionnement de la pompe lorsque la buse est pliée. L'actionneur réduit sensiblement le desserrage de fermeture de pompe (dévissage) et la rupture de buse pendant l'expédition d'un produit rempli en éliminant les poignées de déclenchement ou d'autres types de buse conventionnels qui font saillie depuis le côté de l'actionneur. Par conséquent, le nouvel actionneur est particulièrement bien adapté pour une utilisation dans d'e-commerce où l'expédition de produits sans boîte est de plus en plus fréquente. L'actionneur est configuré de sorte que l'enfoncement de l'actionneur (actionnement) ne puisse pas survenir lorsque la buse pliante est dans une position pliée.
