Definitions

  • the present invention relates to a product dispenser which can be pressurized by the user and to means for pressurizing the dispenser.
  • Containers which dispense both aerosols and other fluids are widely used within the community.
  • the most common form of such dispenser is the prepressurized aerosol can which contains both the product and propellant gas within the same container.
  • Aerosol cans are made from metal, glass or other materials and have a dispensing valve at the upper end and a siphon tube extending within the can to or adjacent to the lower end.
  • gases that are currently being used as propellants include environmentally harmful halocarbons such as fluorocarbons, chloro-fluorocarbons, and modified fluorocarbons; hydrocarbons such as butane, propane and dimethylether (sometimes compressed to liquids); and gases such as carbon dioxide and nitrogen.
  • Aerosol cans are of a convenient size and shape and are of relatively low cost.
  • the cans are instantly ready for use, have an integral dispensing valve, and can be used one-handedly with minimal effort.
  • the cans can be discharged, repetitively and substantially completely.
  • the dispensation is relatively even and well regulated during each discharge and spray cans can be provided with precisely controllable spray patterns and time proportional spray volumes.
  • the use of aerosol cans largely replaced the use of air pump containers and consumers have been reluctant to forego these advantages and return to the use of air pumps notwithstanding urging by environmentalists to do so.
  • the present invention consists in an aerosol can dispenser of the kind comprising a pressurizable tubular container defining an undivided internal volume, the container having a discharge valve mounted at one end and having a base at the opposite end and having a tube communicating from the discharge valve to adjacent the base, said dispenser being characterised in that it has an inlet valve adapted to receive a fluid under pressure from an external supply at the base and in that both the inlet valve and the discharge valve communicate in common with the internal volume.
  • a second tube within the container communicates between the inlet valve and an upper ullage space of the container.
  • a second aspect of the invention consists in a dispenser as described above in combination with a portable fluid charging apparatus, including means to admit fluid under pressure into the container when the container is positioned with the inlet valve in operative axial engagement with said means.
  • the fluid is air and the means to admit the gas under pressure includes a blunt stem nozzle with at least one gas outlet adjacent its end.
  • the charging apparatus is capable of pressurising the container to in excess of 45 psi in from 1 to 10 seconds, preferably from 1 to 5 seconds.
  • a further aspect of the invention consists in a portable compressed fluid charging apparatus for supplying compressed fluid to a portable pressurizable tubular container, said apparatus comprising means for providing a supply of compressed fluid, means for introducing the compressed fluid into the container and means for limiting the pressure of the compressed fluid within the container to a predetermined level.
  • Yet a further aspect of the invention consists in a method of pressurizing a dispenser as described above including the steps of positioning the valve at the base of the container in axial engagement with a compressed fluid charging apparatus, depressing the container with respect to the apparatus to initiate the flow of compressed fluid and to open the inlet valve whereby to admit compressed fluid into the interior volume of the container, and removing the container from the apparatus on the generation of a signal indicating that the container is fully charged.
  • the container of the invention differs from a known aerosol can which is used to dispense greases or the like in which the can interior is divided by a compressible sack wall into two compartments.
  • the sack contains a product to be dispensed in communication with the dispensing valve while a rubber inlet port provides for the space between the sack and the can wall to be pressurized by injection with a propellant gas before the can leaves the factory.
  • both inlet and dispensing valves are in communication with the same space and the container is adapted to be repetitively recharged with a compressed gas by the user.
  • Preferred embodiments of the present invention use conventional mass-produced aerosol can bodies and dispensing valves but differ in that an inlet valve is provided at the base.
  • Such cans cannot withstand an air pressure sufficient to provide for discharge of the whole contents of the can as an aerosol and so require to be refilled with air under pressure several times before a usual "fill" of concentrate is discharged. Hitherto, there has been no suitable apparatus available whereby a consumer could safely recharge an aerosol container with air at the required pressure nor has there been provided an aerosol can adapted to be conveniently and inexpensively recharged with a propellent by the consumer.
  • the container of the invention is able to utilize existing investment in aerosol can packaging machinery as well as in can and valve manufacture.
  • Figure 1 is a schematic diagram of a compressed gas filling system according to one aspect of the invention.
  • Figure 2 is a schematic representation of a portable dispenser according to one aspect of the invention.
  • Figure 3 is a schematic representation of an apparatus for charging the pressurizable dispenser of Figure 2, with the dispenser being inserted into the device;
  • Figure 4 is a view similar to Figure 3 showing the dispenser being charged
  • Figure 5 is a schematic representation of a further embodiment of an apparatus for charging the pressurizable dispenser of Figure 2, with the dispenser being inserted into the device;
  • Figure 6 is a view similar to Figure 5 showing the dispenser being positioned for charging;
  • Figure 7 is a view similar to Figure 5 showing the dispenser being charged
  • Figure 8 is a view similar to Figure 5 showing the dispenser being removed from the apparatus.
  • FIG. 9 is a schematic representation of a charging apparatus according to one aspect of the invention.
  • FIG. 1 With reference to Figure 1 there is shown a schematic diagram which includes a compressed air supply section 10, a filter section 11 and a charging section 12.
  • the supply section 10 has an air inlet filter 13 and a compressor 14 driven by a motor 15.
  • the motor is electrically driven however the air could be compressed in any other conventional way and could be supplied from an external source such as a bulk reservoir.
  • Compressed air from the compressor 14 is delivered through line 16 to a mist separator 17 and from the separator 17 through line 18 to the charging section 12.
  • a branch line 19 provides a vent for dry air to the atmosphere through a pressure relief valve 20 and an audible signal means or orifice 21.
  • Pressure relief valve 20 ensures that the dispenser is charged to a predetermined pressure and the signal means 21 provides a simple indication that the dispenser is appropriately charged. Other kinds of signals could, of course, be used and the vent 19 could be redirected to the supply.
  • Charging section 12 is arranged to receive and charge a dispenser having a reusable gas inlet valve. Condensed water from separator 17 exists via a suitable evaporator tray 22 with resistance heating. Alternatively the water can be exhausted via a pressure regulator and audible signal orifice.
  • Figure 2 shows a dispenser 30 consisting of a pressurizable tubular container with a conventional discharge valve 31 mounted at one end and having at the opposite end 32 a base with an inlet valve 33.
  • Base 32 is formed from an inwardly domed disc and the inlet valve 33 is positioned centrally on the dome.
  • Container 30 is conventionally charged with an active ingredient 34 and has an ullage space 35 above ingredient 34.
  • a tube 36 connects inlet valve 33 with this ullage space 35.
  • a further tube 37 depending from discharge valve 31 extends to adjacent the base of the container to draw active ingredient 34 during discharge.
  • container 30 can be sold pressurized or not and the user can repressurize the container using a charging apparatus, which will be described below, to admit a compressed gas into the ullage space 35 via the inlet valve 33 and tube 36.
  • Container 30 can thus be recharged until there is substantially little or no active ingredient 34 remaining. Furthermore as it is preferable to recharge the container with compressed air there is no hazardous chemical propellant used.
  • Figures 3 and 4 show the container 30 being placed on a charging apparatus 40.
  • the top of the apparatus 40 forms a platform 65 onto which the base 32 of container 30 is placed.
  • An open locating shoulder 50 mounted on platform 65 surrounds a blunt stem nozzle 44 projecting from platform 65.
  • inlet valve 33 passes through the space inside locating shoulder 50 to engage with nozzle 44 which in turn opens valve 33 to admit gas.
  • a manual switch 66 activates flow of compressed gas into inlet valve 33.
  • a pressure relief valve 47 activates an audible signal and the flow of gas is switched off.
  • the interior of the apparatus 40 defines a reservoir 67 which is pressurised from a remote compressed gas source (not shown) and used to charge container 30 when needed.
  • the remote source can be a centrally operated compressor, a prepressurized cylinder, or any other source.
  • the capacity of the compressor is below 1000 cc/sec. and preferably about 2500 cc/sec. in contrast with commercial filling machines which operate at about 30,000 cc/sec.
  • apparatus 40 will charge container 30 to in excess of 45 psi in from 1 to 10 seconds.
  • a series of radially extending circles 68 on platform 65 assists in centrally locating container 30 thereon.
  • a drip groove 51 around the periphery of platform 65 collects any accidental spills.
  • Apparatus 40 is shaped so as to accommodate the base of the container 30, the walls 38 defining a chamber 41 with a locating piston 42 positioned therein.
  • the locating piston 42 is biased by way of spring 43 in a raised position.
  • the blunt stem nozzle 44 extends from the base of the chamber 41 towards the piston 42.
  • a source of compressed gas 45 is in communication with nozzle 44 through duct 46 and a pressure relief valve 47 vents the compressed gas to the atmosphere upon the container 30 being fully charged. Again the compressed gas source could be remote from the apparatus 40, or integral therewith.
  • the base of the container 30 is positioned on piston 42 which includes aperture 48 to receive nozzle 44 as the piston passes the nozzle. Nozzle 44 then engages with and opens the inlet valve 33.
  • Figure 7 shows piston 42 being depressed by the weight of the container 30, and actuating a microswitch 49 on the side wall of the chamber 41 to initiate the flow of compressed gas. The compressed gas is then admitted under pressure into container 30.
  • pressure relief valve 47 activates an audible signal and container 30 is removed from the charging apparatus 40.
  • blunt stem nozzle 44 is preferred in comparison with needle style nozzles as it is safer for use in a consumer environment.
  • Piston 42 has upwardly extending fingers 53 to assist in centrally locating container 30 on the piston 42. As piston 42 is depressed fingers 53 align with side walls 38 of chamber 41 to hold container 30 in place. A retaining ring 54 holds piston 42 within the chamber 41.
  • Figure 9 shows an open locating shoulder 50 surrounding aperture 48 so that any leakage of the contents of container 30 will collect on the outer face of piston 42.
  • a pedestal on inlet valve 33 enters the space within locating shoulder 50 to engage with nozzle 44.
  • Groove 51 on the periphery of this outer face of the piston again collects any such spills.
  • a non-return valve 61 on the charging unit also minimises the possibility of contaminants entering the unit.
  • a series of radially extending circles 68 on the outer face of piston 42 also assist in centrally locating the container 30.
  • the source of the compressed air is shown in Figure 9 to be a miniature motor driven compressor 60 with a limited capacity so that the container cannot be overcharged.
  • a pressure relief valve 62 vents the excess compressed air to the atmosphere and generates an audible signal as above.
  • the inlet valve 33 of the container 30 is ideally an airlock valve with a first seal which is opened by the nozzle and a second seal which is opened due to air pressure.
  • a further design of the inlet valve includes a plurality of O-rings or a tubular seal.
  • the apparatus 40 also operates in a standby mode in which container 30 sits within the apparatus when not in use, with nozzle 44 having opened the first seal of valve 33.
  • Apparatus 40 senses when the charge of propellent in container 30 is low and initiates the flow of compressed gas which in turn opens the second seal in the inlet valve 33 to allow entry into the internal volume of container 30.
  • the pressure relief valve 47 indicates that the container is fully charged.
  • a preset pressure switch may be used automatically to initiate the flow of gas when the container is connected to the charging apparatus, the pressure switch having a high cut-off point and low turn-on point to maintain a working range of pressure without intervention.
  • the above embodiment referred to depression of the piston due to the weight of the container, however the spring can be rated so as to require further force to depress thus avoiding accidental operation.
  • the container 30 has been shown with a female inlet valve the apparatus could incorporate a female receptacle and the container a mating male valve.
  • the combination apparatus 40 and container 30 have herein been described in use in the upright position, however the system will work equally as well in an inverted position in which the container is pushed up, or sideways, into the apparatus in order to connect with the compressed gas source.
  • the use of differing diameters and profiles for the container base and apparatus chamber will allow only the use of compatible dispensers and charging apparatus. This will prevent containers with limited capacities being charged with higher rated units and prevent charging with a non-suitable compressed gas. Manufacturers will also be able to sell matching containers and charging units to suit the specific requirements.
  • the aerosol can be made from any suitable materials by conventional methods.
  • the dispensing valve can be of any suitable type.
  • the inlet valve can be of a type different from the dispensing valve and those skilled in the art will have no difficulty in selecting a suitable inlet valve mechanism. In some cases a self-sealing rubber inlet suitable for repetitive needle injection may be used.

Abstract

Un distributeur à bombe aérosol (30) comprend un récipient tubulaire pressurisable dont le volume interne est indivisé. Une soupape de sortie (31) est montée à une extrémité et est reliée à un tuyau (37) qui s'étend jusqu'à une position contiguë à la base (32). Une soupape d'admission (33) située dans la base (32) reçoit un fluide sous pression provenant d'une source extérieure. A la fois la soupape d'admission (33) et la soupape de sortie (31) sont reliées en commun au volume interne. Un appareil (40) de chargement de fluide possède un ajutage (44) afin d'admettre du fluide sous pression au récipient (30) lorsque celui-ci est placé sur l'appareil (40) et que la soupape d'admission (33) est couplée à l'ajutage (44). La dépression du récipient (30) par rapport à l'appareil (40) initie l'écoulement de fluide comprimé et ouvre la soupape d'admission (33) afin d'admettre le fluide dans le volume interne. Le récipient est enlevé lorsqu'un signal est généré.
