Definitions

  • An aerosol container or sprayer comprises a container proper, for instance in the form of a metal can, a flask or a bottle, containing the substance that is to be sprayed, say an insecticide, and a propellant gas, such as Freon, and an aerosol valve with which the container is closed.
  • aerosol valve There are two kinds of aerosol valve.
  • the other type of aerosol valve which is generally applied to glass bottles has the form of a cap, usually consisting of sheet aluminium, the actual valve being contained in the cap which is pushed over the neck of the bottle and affixed, in contradistinction to the method of fixing the first described type, by deforming the cap around the neck of the container from the outside.
  • a can is prepared for filling before it is loaded into the machine by placing a disc valve loosely on to the mouth of the can.
  • the can is then presented to the working head of the machine, which descends and makes sealing contact with the shoulder of the can around the circumference of the valve.
  • the valve is slightly lifted by suction generated by a vacuum pump.
  • a liquid propellant gas is then forced through the gap between the valve and the top of the can.
  • the valve is pushed back on to the top of the can and then pressed from the inside against the inner wall of the mouth of the can by sealing instruments built into the closing means. When the operating tools have returned into their former positions .the filled and sealed can is removed.
  • the disc valve which is placed on the top of the can has a downwardly open cylindrical cup of substantially the same diameter as the inner edge of the mouth of the can. If this valve is not introduced in a precisely vertical direction but at a slight angle it will immediately jam, preventing the vacuum pump from lifting the valve. If the valve does not rise the substance which is to be filled into the can cannot enter between the top of the can and the valve and is therefore spilled on the top of the valve. The valve is thus even more firmly held down and the entire filling is wasted. Since this is nearly always a propellant it will explosively vaporize. If the propellant gas contains additives such as pigments, then the surroundings on the factory floor may be badly spattered. Moreover the explosive spatter of liquid may cause injury, particularly to the eyes of personnel.
  • aerosol valves are fitted with dip tubes or risers made of a plastic material, such as polyethylene, which is unwound from a bobbin and cut to length. These tubes therefore nearly always curl. Moreover they are so long that they already touch the floor of the can before aerosol valve is pressed against the valve rests on the top of the can for closing the same.
  • Such bent riser tubes are often the cause of valves assuming a canted position in the mouth of the can or even of springing out of the opening and coming to rest on the top of the can in an eccentric position. Both causes, namely jamming due to a nonhorizontal or eccentric position of the aerosol valve in relation to the opening in the can are responsible for frequent trouble in mass production. There is therefore often considerable wastage which far exceeds that experienced in other methods of closing and filling aerosol cans.
  • the object of the present invention is to provide a method as well as an apparatus for overcoming the above described difiiculties and for securing certain other advantages.
  • Jamming of the valves due to non-horizontal position or the crushing of valves by the descending closing means when the valves are in an eccentric position is avoided by the present invention in that the filling head is traversed by an upwardly open longitudinal closing channel extending in coaxial alignment with the mouth of the container which is to be filled.
  • the container is placed underneath this head and the valve is dropped into the longitudinal channel from above.
  • a closing element then enters the longitudinal channel and propels the valve downwards, but not far enough to prevent the container from being filled through a remaining gap between the valve and the container top.
  • the valve pushed down on to the container or flask.
  • the provision of the said longitudinal closing channel therefore permits the aerosol valve to be presented to the container in a precisely axial and central position and at the same time it eliminates the causes of trouble in known filling methods because the aerosol valve need not be lifted before filling begins, and jamming cannot occur because the valve does not make contact with the container until the latter has already been filled.
  • apparatus according to the invention does not require a vacuum pump for lifting the valve. This is a matter of special importance because the machine based on the proposed apparatus can be fully pneumatically operated without electric power, so that inflammable propellant gases, suoh as butane and propane, can be handled without the hazard of fire.
  • the usual vacuum pumps on the market are all driven by electric motors. The absence of such pumps is therefore a special advantage of apparatus according to the invention.
  • valve In machines hitherto known to the art the valve must be placed on the container month before being loaded into the machine. Apart from fully automated installations, and particularly in smaller and medium sized establishments, two men are therefore needed, namely one for placing the valve on the container and pushing it towards the machine and a second for operating the actual machine. In apparatus according to the invention one man can place the container in loading position and at the same time feed the valve into the closing channel. In other words, such a machine can be entirely operated and run by only one man.
  • valves for glass flasks and bottles can be handled in the same way as disc valves and the same advantages obtained as described.
  • the invention provides a method which also permits glass bottles and similar containers to be conveniently filled without spillage through the gap underneath the raised valve.
  • the seal is not formed on the shoulder of the bottle but by the top edge of a receptacle into which the flask or bottle is placed before being filled.
  • a filling tube adapted to be introduced into the mouth of the bottle discharges the liquid directly into the bottle and prevents it from entering the space between the bottle and the filling head, as is the case in known filling methods.
  • the provision of the longitudinal closing channel ensures that the valve is introduced and presented to the bottle opening in a precisely centered position, permitting the valve to be affixed to the mouth of the bottle in an absolutely reliable and pressure-tight manner by sealing instruments which close on the bottle neck from the outside.
  • the receptacle used in the method proposed by the present invention also permits metal cans to be fitted with disc valves for instance in cases in which the diameter of the can does not exceed or is only slightly larger than the diameter of the disc valve. In such a case a shoulder on the can is not needed for forming a sealing contact surface with the filling head.
  • FIG. 1 is a schematic elevational section of apparatus according to the present invention, principally intended for filling and closing aerosol flasks made of glass, plastics or metal,
  • FIG. 2 on a larger scale shows the neck of a flask at the instant an aerosol valve is fitted thereto
  • FIG. 3 is a schematic elevational section of modified apparatus according to the invention, principally intended for filling and closing metal aerosol cans with a conventional 1 aerosol disc valve,

  • a pneumatic cylinder 1 provided with air entry and outlet openings 2 and 3, a piston 4 with a sealing ring 5 and a piston rod 6 supports a receptacle 7 into which the aerosol flask 8 which is to be filled is insertable.
  • piston til 5 is first completely retracted by the introduction of air through opening 3 and by exhausting air through opening 2.
  • the filling head 11 contains a longitudinal closing channel 12 into which the aerosol valve 13 is dropped.
  • a longitudinal closing channel 12 into which the aerosol valve 13 is dropped.
  • the inside wall of the filling head contains a ball 14, urged to project into the channel by the pressure of a spring 15.
  • the longitudinal closing channel is fitted with a sealing sleeve 16 adapted to form a seal between the walls of the channel and the plunger 17 of a ram 18.
  • the ram comprises a two-stage cylinder 18 containing two pistons 19 and 20 and provided with air entry and outlet openings 21, 22 and 23.
  • the two pistons are fitted with sealing rings 24 and 25 respectively. If air is admitted at 21 piston 20 is forced to descend and its piston rod 26 pushes piston 19 and its piston rod 27 and a plunger 17 downwards until the aerosol valve 13 in the channel of the filler head is intercepted by the projecting ball 14. Ring 16 forms a seal between the moving plunger 17 and the inside of the filling head.
  • a filling tube 28 which passes through a gland 29 in the filling head is advanced by a pneumatic cylinder 30 until the end of the tube is well inside the flask 8.
  • the filling tube is advanced and retracted by admitting and exhausting compressed air through openings 31 and 32 respectively.
  • Piston 33 which is provided with a sealing ring 34 is thus retracted or advanced and carries the filling tube with it.
  • the filling tube is connected by a flexible pipe 35 to the filling valve 36 of a metering pump 37.

  • inlet valve 42 opens and the cylinder fills with the liquid which is to be pumped into the aerosol flask.
  • the piston or its piston rod 40 is fitted with adjustable stop means for regulating the stroke.
  • piston 38 descends the filling valve 36 opens and the product, for instance a liquid propellant gas such as Freon, is forced through tube 28 into the aerosol flask 8.
  • valve is then secured by the application of radial pressure by an assembly of closing instruments 43 which press the edges of the valve against the periphery of the neck of the flask, deforming the valve immediately below the thickened lip of the aerosol flask 8.
  • FIG. 2 illustrates the manner in which the closing instruments 43 push the edge of the aerosol valve 13 against the neck of the glass flask 8 below the thickened lip 8a of its mouth.
  • the deformation of the aerosol valve simultaneously causes a rubber washer 13a inside the aerosol valve 13 to be pulled tightly down on to an annular rib 8b projecting from the top of the lip of the flask, thus ensuring the formation of a reliable air-tight seal between valve and flask.
  • the closing instruments 43 are forced inwards by the downward thrust of a bevel ring 44 which cooperates with pins 45 to which the closing instruments are attached and pushes them radially inwards.
  • a bevel ring 44 which cooperates with pins 45 to which the closing instruments are attached and pushes them radially inwards.
  • the pins 45 are free to be retracted radially outwards by the pull of springs 46.
  • Ring 44 is actuated by a piston 48 which carries a sealing ring 49, and which is reciprocable in a cylinder 47.
  • Piston rod 50 carries a disc 51 connected to ring 44 by several vertical columns 52.
  • Air can be admitted into cylinder 47 through openings 53 or 54 for lowering or raising the piston 48 as may be required. Finally, compressed air is introduced through opening 3 into cylinder 1 and the receptacle 7 is thus withdrawn downwards away from the filling head 11, permitting the filled and closed flask to be taken out of the receptacle. By admitting air through opening 23 the two pistons 19 and are lifted and the plunger 17 is withdrawn from the longitudinal channel, so that a fresh aerosol valve can be dropped into the top of the channel. Cylinder 1 is pivotably mounted on a base 56, permitting the cylinder to be swung away from the machine and glass flasks to be conveniently loaded into or taken out of the receptacle.
  • FIG. 8 illustrates the construction of such an element.
  • This may have the form of an elastically flexible funnel 55 with a plurality of slits extending upwards as far as its horizontal fixing flange. The end of the dip tube will then safely slip into the inside of the flask through this funnel.

  • piston 105 is first lowered by the admission of compressed air through opening 103 and the exhaustion of air through opening 102.
  • air is admitted through 102 and exhausted through 103.
