Definitions
- the present invention relates to an aerosol bomb which utilizes compressed air as propellant and can be refilled by a suitable refilling device.
- An aerosol bomb contains products under pressure which can be sprayed in nebulized form due to the propelling action of a liquefied gas.
- products can be sprayed: toilet products, insecticides, foodstuffs, a.s.o.
- the reservoir usually of metal contains the active component to be sprayed along with the liquefied propellant, such active component being stored in the reservoir under liquid state or in solution form.
- Fluoridized hydrocarbons (freon), ethyl chloride, nitrogen oxide, a.s.o. are widely used as propellant.
- propellant and container are much more expensive than the active component. Moreover propellant and container can cause serious problem of pollution. In fact freon and fluorochloride are the most important causes of the reduction of the ozone layer.
- the apparatus of this invention seeks to avoid pollution and to make the use of the aerosol bombs considerably cheaper by utilizing compressed air as propellant and reusing the same container once exhausted the content.
- DE-U-88 08 407.8 discloses a device for refilling under pressure an aerosol bomb having a filling valve, which device is provided with a pressure tank and an electric delivery pump for the propellant which is operated by the bomb itself when the latter is in the refilling position. Such device does not allow, however, to either determine in advance the amount of liquid to be fed to the bomb or to adjust the pressure within the bomb.
- the refilling device of the present invention which provides in combination a bomb which can be refilled and is provided with an atomizing valve, a refilling tank containing both the product to be nebulized and compressed air as propellant at a predetermined pressure, rapid-connect means coupling said bomb to said tank, and means to control the intake and the pressure of the compressed air from an outer source into both said refilling tank and said bomb through said rapid-connect valve.
- the apparatus comprises in combination a bomb I of the size normally used for atomizers and a closed tank H which can be refilled.
- Bomb I is provided at the upper side with an atomizing valve A and a bleed valve B, and at the lower side with a check valve C and a rapid-connect valve D intended to cooperate with a corresponding rapid-connect valve E wich is provided at the upper side of tank 6.
- the connection of the two valves is preferably of the male-female type.
- the rapid-connect valve E draws the liquid to be nebulized from the bottom of the tank through pipe P.
- the tank is subjected to the desired pressure relative to a preliminary filling of bomb I (for example 1/4, 1/3, 1/2, a.s.o. ) through a pressure regulator R placed in the intake conduit N of the compressed air from any outer source.
- the compressed air from the outer source is also conveyed to the rapid-connect valve E through a second pressure regulator S, branch pipe Q and cock F.
- cock F in branch pipe Q is closed and cock G in pipe P is opened so that bomb I is filled with the liquid to be nebulized from tank H. Subsequently, cock G in pipe P is closed and cock F in branch pipe Q is opened so that air at the desired pressure to have a proper jet can be injected into the bomb.
- the refill of tank H with the liquid to be nebulized is performed through an opening closed by plug M.
