Definitions

  • the movable or deformable partition is constituted by a pocket which is either of flexible plastic material, such as low density polyethylene, or of pure aluminum, coated.
  • This pocket has a single opening.
  • the diameter of this opening can be substantially equal to that of the opening of the container and in this case, the pocket is intended to be taken in the crimping by which the closing valve is fixed on the container, or the diameter of the 'opening is close to that of the container and, in this case, the pocket is intended to be taken in the crimping of a flange forming a cover and on which the valve is crimped.
  • document US-A-4150522 on which the preambles of claims 1 and 13 are based, relates to a method of filling an aerosol container under a cup, in which a bag is positioned inside the container, after which said bag is filled with the product to be packaged and the vacuum is then applied between the container and the bag filled with product, before introducing the propellant.
  • the object of the invention is to provide a process for filling such boxes, sheltered from the atmosphere and without alteration of the substance to be packaged, even when fragile, this process being simple to construct and implement, and therefore inexpensive.
  • Another object of the invention is to provide an installation for the implementation of such a method.
  • the present invention therefore provides a method of filling an aerosol container with valve, comprising two compartments, the first of which is connected to the valve, separated by a flexible or movable partition, and according to which the substance to be packaged is introduced into the first compartment. , this compartment is closed, then a propellant fluid is introduced or produced in the second compartment.
  • a propellant fluid is introduced or produced in the second compartment.
  • the valve of the box is placed definitively before the introduction of the substance to be packaged. then said substance is introduced into the first compartment by passing it through the valve.
  • the material to be packaged is viscous, such as glue or paint, it is better to operate differently, but at a price an additional complication, and the valve is then placed after the introduction of the substance, in order to close the first compartment.
  • a vacuum is made in it while taking precautions so that its volume remains at least equal to the volume of substance that it is desired to introduce therein and the substance is introduced into said first compartment without breaking the vacuum.
  • a vacuum is made in the second compartment. This modality is more particularly, but not exclusively, suitable for filling a case where the partition separating the two compartments consists of a deformable sheet of metal or plastic.
  • the propellant is produced in a staggered manner during the use of the substance, inside a deformable pocket, constituting the second compartment and introduced into the box before it is closed, it is preferable to use a pocket deformable which has been sealed under vacuum, and that this pocket is introduced into the first compartment which is emptied of air before introducing the substance therein.
  • the partition separating the two compartments is constituted by a movable piston
  • the volume of the latter is reduced by deformation or displacement of the flexible or movable partition, then the substance is introduced into the first compartment by increasing the volume thereof.
  • the metering device comprises a metering capacity which can be connected to the first compartment via a distributing valve and according to a simple embodiment which is applicable to substances of low viscosity, the metering capacity is placed at the -above the aerosol can and the substance is passed from the metering capacity into the first compartment by gravity.
  • the metering device comprises at least one metering pump.
  • the second compartment is emptied and / or filled using a hollow needle of the hypodermic type perforating said plug.
  • the present invention also provides a device intended to be implemented according to the method just described.
  • It is a device for filling an aerosol container with two compartments separated by a flexible or movable partition comprising means for holding said container in a filling station with the opening of a first compartment of said container facing the top; means for pouring a metered quantity of the substance to be conditioned into said first compartment; means for fixing a discharge valve of said substance on said opening of the first compartment; and means for introducing or producing a propellant fluid in a second compartment of said container (known for example from document US-A-4150522), characterized in that it further comprises means for removing most of the air contained in the first compartment before the introduction of said substance, and means for protecting said substance from contact with air during said introduction and during the fixing of the valve.
  • the device comprises a first device comprising a first conduit capable of being connected in leaktight connection with the first compartment, a second conduit connected to a vacuum source, a metering pump capable of delivering the desired quantity of substance and a valve capable of connecting the first conduit, either to the second conduit, or to the outlet of the metering pump; a second device capable of placing and fixing the valve of the container on the body thereof without bringing the interior of the first compartment into contact with the atmosphere; and means for successively bringing the first and second apparatus into contact with an aerosol can body without putting the first compartment thereof in contact with the atmosphere during the corresponding relative movement.
  • the device may further comprise a third device capable of delivering a deformable bag intended to constitute the second compartment inside the aerosol can and means capable of putting said aerosol can in contact with said third. switchgear before putting it into contact with said first switchgear.
  • the device further comprises a hollow needle of the hypodermic type; means for introducing the end of the needle into the second compartment, and means for connecting the interior of the needle separately to a source of vacuum and to a source of propellant.
  • the reference 1 designates an aerosol container, seen in section, comprising an interior partition 2, made of aluminum, which divides the interior space into two compartments, a first compartment 3 connected to the valve 4, which is of a conventional type, and a second compartment 5, which surrounds the first over almost its entire periphery, and which can be filled with propellant, under pressure or liquid, through a hole 6, provided in the bottom of the container and closed by a plug 7 made of neoprene rubber or similar material.
  • the container 1 is placed on a support 8 which is part of the filling device, and it is held at its upper part by a cross member 9, provided with collars or fixing brackets, not shown and integral with the support 8.
  • Two vertical slides 10 also integral with the support 8 support the filling means of the first compartment 3.
  • These filling means comprise a pre-dosing capacity 11, the volume of which corresponds to that of the compartment 3.
  • Several interchangeable pre-dosing capacities, of different volumes, are provided to allow the filling of 1 different containers.
  • the predosing capacity is placed above the container 1, and is substantially in the axis thereof.
  • a channel 12, provided with a solenoid valve 13 is located at the lower part of the capacity 11.
  • the solenoid valve 13 like the other solenoid valves described below, can be replaced by a manual control valve in a simplified version, or by a pneumatic, mechanical or other valve.
  • the channel 12 and the solenoid valve 13 are carried by a cross member 15, which is connected to the lower part of the tank 11, and which can slide along the slides 10 between a low position where the seal 14 comes to ensure the connection between the channel 12 and the compartment 3, via the valve 4, and a high position (not shown) where the channel 12 is separated from the container 1.
  • a low position where the seal 14 comes to ensure the connection between the channel 12 and the compartment 3, via the valve 4, and a high position (not shown) where the channel 12 is separated from the container 1.
  • known means and not shown such that a pusher, keep the valve 4 in the open position, these means allow the valve to close when the cross member 15 deviates from the low position.
