Definitions

  • the present invention relates to dispensing devices such as aerosol or liquid dispensing devices, and more particularly, to dispensing devices having an oscillating dispenser pump.
  • WO 03/037748 A1 discloses an automatic periodic aerosol dispenser based on pressurized gas as a pressure source for long-term periodic dispensation using an accumulation chamber. This dispenser may be used for example for repeated refreshing an active in the air.
  • Other dispensers are based on pressurized gas, e.g. as disclosed by EP 0 062 341 A1 , or a manual pump as a pressure source, e.g. as disclosed by US 3,231,153 A , US 3,861,570 A , US 3,870,205 A , US 4,139,128 A or US 4,416,398 A , wherein the dispense rate is variable according to the actuation of a valve.
  • a dispense rate is increased when actuation of the valve is increased, e.g. as disclosed by GB 2 312 478 A1 .
  • Such conventional dispensers generate a dispersion or an aerosol.
  • applications wherein not only a chemical reaction is desired but small mechanical actions or impressions improve the user's feeling and well-being and the total effect.
  • scalp tonics it is desirable for scalp tonics to generate a thin jet of liquid for massaging the scalp in order to improve the effect of the tonic, which is impossible if the product is merely dispersed because the mechanical effect to the skin is rather low.
  • a spray head of a conventional dispenser e.g. as disclosed by the above references, has to be modified.
  • a pre-compression valve is arranged in the pump conduit, which is pressure-controlled and opens if a certain pressure threshold is exceeded.
  • the pre-compression valve cooperates with a spring having a high spring constant.
  • the additional valve is closed until the pressure threshold is exceeded.
  • the valve opens at a pressure above the pressure threshold and liquid is dispensed until the pressure provided by the pump falls below that certain pressure threshold.
  • the nozzle is recessed with regard to the dispenser opening leading to a thin jet of liquid instead of an aerosol. In this way, an oscillating dispensation of liquid during manually pumping is provided because of the pressure variation caused by the product outflow.
  • the pulsation effect can be preferably improved by the use of an actuating lever.
  • increasing the spring constant of the additional pre-compression valve serves to accelerate the function of the valve.
  • pre-compression valve is to be understood as a valve associated with an outlet, requiring a certain level of force against it, and hence fluid pressure, in order to open and allow the flowable material to escape.
  • the output from the dispensing device can be of desirable form, for example a jet or spray.
  • the pre-compression valve is designed so that when flowable material is being pumped it is opened by the pressurisation of the flowable material, without mechanical intervention. However during a priming operation when it is air that is being compressed, it is preferably arranged not to be opened by the air. Rather, mechanical intervention is required to open the pre-compression valve during this phase, and allow the air out.
  • a dispenser 10 may be attached to a can 12 or container which is only partly shown and includes a cylindrical wall 14 that is closed at its upper margin 16 by a closure 18 which comprises a radially extending portion 20 inserted in an correspondingly shaped slit 22 of the wall 14.
  • the closure 18 receives a pump assembly 24 within a central opening 26 thereof.
  • the pump assembly 24 includes a spray cap 28 or button and defines a cavity in which a spray insert 30 is seated.
  • the spray insert 30 is composed of a nozzle 32 and a spray orifice 34.
  • the nozzle 32 and the spray orifice 34 may be configured to develop a suitable spray pattern. Particularly, because the nozzle 32 is recessed if compared to nozzles of conventional spray caps, the supply channels are out of order because the nozzle 32 is not recessed up to a stopper or stop position.
  • the spray cap 28 is seated on and secured to an elongate and cylindrical adapter 36.
  • An upper end of the adapter 36 is snugly received in a tubular recess defined by the spray cap 28.
  • the cylindrical adapter 36 defines an axially extending passageway 38 through which material to be dispensed from the can 12 is adapted to pass to the spray orifice 34 for discharge.
  • a stem 40 of a valve 42 is seated in an enlarged bottom end portion of the adapter 36.
  • the stem 40 includes a generally upstanding portion 44, which is seated in the passageway 38, a base 46 that extends generally radially outwardly from the lower end of the upstanding portion 44 and a lower portion 48.
  • the base 46 has a peripheral edge 50.
  • the pump assembly 24 further includes a valve body 52 that is secured to the closure 18, for example by means of a latch or a snap-in lug.
  • the valve body 52 defines an interior pressure chamber 54 for containing material to be dispensed through the spray orifice 34.
  • the stem 40, adapter 36 and spray cap 28 are normally maintained in their upper position by means of a spring 56 which bears against the bottom of the base 46 of the stem 40 and is supported on a lower end portion 58 of the pressure chamber 54.
  • the spring 56 has a greater spring constant if compared with springs of conventional pumps for dispensers.
  • a small gap 60 is defined between the base 46 and the cylindrical wall of the pressure chamber 54.
  • the passageway 38 within the adapter 36 comprises a narrowed portion 62 and the upstanding portion 44 of the stem 40 comprises a conical upper end 64.
  • the conical upper end 64 forms a pre-compression valve and the narrowed portion 62 forms the valve seat of the pre-compression valve as will be explained below in more detail.
  • the base 46 is not sealed against the lower end of the adapter 36.
  • the conical upper end 64 is not disposed within the narrowed portion 62 but spaced apart a small distance, which means that the pre-compression valve is not closed.
  • the stem 40 and adapter 36 are moved downwardly by applying a pressing force onto the spray cap 28, the conical upper end 64 is disposed within the narrowed portion 62, which means that the pre-compression valve is closed.
  • the pressure in the pressure chamber 54 is increased as the volume of the pressure chamber 54 decreases as there is only a small gap 60 between the peripheral edge 50 and the wall of the pressure chamber 54. Thereby, a small flow path is provided over that peripheral edge to an upper side 66 of the base 46. Accordingly, the increasing pressure acts on the upper side 66 of the base 46 and forces the stem 40 further downwards such that the conical upper end 64 is spaced away from the narrowed portion 62. Thereby, the pre-compression valve is opened and permits fluid to pass upwardly through passageway 38 and out through orifice 34. As liquid is admitted to the pressure chamber 54, a negative pressure would tend to develop in the container 12 if venting did not occur. Therefore, to maintain atmospheric pressure in the container 12, ambient air is permitted to replace withdrawn liquid through a not shown passage.
  • the pressure within the pressure chamber 54 is decreased and falls below a threshold determined by the spring constant of the spring 56 after a certain time such that the stem 40 moves upwards and the conical upper end 64 is disposed within the narrowed portion 62, which means that the pre-compression valve is closed again.
  • the pressure within the pressure chamber 54 subsequently increases again because the pre-compression valve is closed at that time and the fluid may not enter the passageway 38 such the pre-compression valve opens again if the pressure threshold is exceeded again after a certain time.
  • the pre-compression valve opens and closes in a fast series during for example a single pressing operation of the pump assembly 24. For example, if a liquid is stored in the can 12 a jet of the liquid is expelled from the orifice 34 in an oscillating and pulsating manner.
  • the can 12 may store a cosmetic product, e.g. a hair tonic.
  • a cosmetic product e.g. a hair tonic.
  • the supply channels are out of order because the nozzle is not recessed up to the stopper.
  • the cosmetic product may directly be expelled out of the nozzle hole and has not to be put into rotation by means of the supply channels. Thereby, the flow resistance is decreased.
  • the above effect is improved if the pump assembly is activated by means of a lever cap. Thereby, the activation way is longer and the velocity is reduced. Thus, the pump assembly and, as a result, the jet expelled from the nozzle 32 is slower pulsated but the above effect is clearly recognizable.
