Definitions
- the present invention relates to a device for improved spraying for a fluid or pasty product, and more particularly a device for spraying the biphasic type.
- This device type has a product container on which is mounted a first pump to dispense selectively the product contained in the container, said pump being actuated by a plunger having an orifice outlet, a second pump for supplying to said orifice outlet a stream of compressed air simultaneously with the product distribution, thereby improving quality spraying, said second pump comprising a piston sliding in said pusher.
- This kind of device allows, upon actuation of the pusher, to distribute the product in the container together and the flow of compressed air from the second pump. So, the product is further sprayed with this compressed air flow.
- the device is of complicated construction and therefore relatively expensive to manufacture and assemble.
- the pump piston generating the air flow tablet is mounted on the pump body, which consequence that this pump body must be adapted to receive such a piston element. possible to adapt this two-phase pump device to a standard pump.
- the fact that the element of compressed air pump piston is mounted on the body pump the method of mounting such a pump biphasic is made more complicated.
- the height of the pump biphasic is relatively high which increases correspondingly the total volume of the device as a whole.
- the object of the present invention is to provide a fluid or pasty product spraying device but in particular a spraying device of the type biphasic, not reproducing the aforementioned drawbacks.
- the present invention aims to providing such a spray device of the type biphasic which is simple and inexpensive to assemble and manufacture.
- the present invention further aims to providing such a spray device of the type biphasic in which a standard pump can be used and which can be assembled on the same assembly line by modifying only a minimum of constituent parts of the device as a whole.
- the present invention has still aim to provide such a device biphasic type spray which has a height pump and therefore a minimum overall volume.
- the present invention therefore relates to a device adaptable spraying of fluid or pasty products on a product container, a first pump for selectively distribute the product contained in said container through an outlet, said first pump being mountable on the container by means of a member fastener, and a movable manual actuator between a rest position and a position actuation, said device further comprising a second pump to distribute compressed air simultaneously with the distribution of the product, said second pump comprising two elements, which are a piston and a pump cylinder in which said piston slides, said second pump being adapted to supply to the outlet opening a compressed air flow for spray the product, one of said two elements of said second pump being fixedly mounted around said member of fixing of said first pump and the other of said two elements is integral with the actuating member, characterized in that said piston of the second pump is formed by a flexible ring secured to a mounted ring fixedly around the fastening member of the first pump, said ring sliding in a sealed manner in a pump cylinder formed in the actuator when it is moved to its position
- the spraying device according to the invention can be assembled at low cost because the first pump, the container, and the fixing member of the first pump on the container can be of type standard and can therefore be assembled in the same chain only spray devices which do not are not of the biphasic type.
- the manufacturing and assembly of the the invention is therefore simpler, faster and less expensive.
- said piston of the second pump is secured to the ring and slides in the cylinder pump formed in the actuating member said cylinder of pump being connected to said outlet port by a air duct.
- said air duct comprises a valve suitable for opening when the air included in the pump cylinder is compressed to a predetermined level.
- the spraying device further includes an expulsion chamber connected to the first pump, to the second pump and to the outlet, the product and the compressed air being mixed in said expulsion chamber before being sprayed by the outlet.
- the volume of the pump cylinder is about zero when the actuator is in its actuation position.
- said ring comprises means for snap-fitting around said member of fixing of the first pump.
- said outlet orifice is formed in said ring, so that it remains fixed for actuation of the device.
- the device for spraying comprises a first pump 10 adapted to selectively distribute the fluid and pasty product contained in a container (not shown).
- This pump 10 can be of any type, and advantageously of the type standard, i.e. of the type commonly used in conventional product distribution systems fluids, well known in the art.
- said first pump 10 is mounted on the container by means a fixing member 11 which can be of any type, such as a snap ring or a snap ring crimping.
- the device comprises further an actuator 30 adapted to actuate said first pump 10 for selectively distributing the container product.
- the actuator 30, which is with manual actuation, can for example be a pusher.
- the spraying device has a outlet 31 through which the product is expelled.
- said spraying device further includes, near the outlet orifice 31, a nozzle 38 to ensure good spraying of the product.
- the biphasic spraying device further includes a second pump 20 suitable for distributing compressed air simultaneously with the product distribution.
- This second pump 20 comprises a piston 21 which cooperates with a pump cylinder 22 for supply an air flow to outlet 31 compressed.
- the piston 21 slides in a pump cylinder 22 formed inside the actuating member 30.
- the pump cylinder 22 is filled with air and when the organ actuator 30 is actuated to dispense product contained in the container, the cylinder 21 slides in the pump cylinder 22, thereby compressing the contained air in the pump cylinder 22, so that the actuation of the actuator 30 causes an air flow compressed in the direction of the outlet orifice 31.
- the pump cylinder 22 is advantageously connected to said outlet orifice 31 by means of an air duct 32, as shown in Figures 3 to 6.
- said air duct 32 includes a valve 33 closing said air duct 32, which is adapted to open only from a predetermined level of pressure prevailing inside of the pump cylinder 22.
- a valve 33 closing said air duct 32, which is adapted to open only from a predetermined level of pressure prevailing inside of the pump cylinder 22.
- the actuator 30 is in its actuation position 30, shown on the figure 2
- a dose of product was expelled from the container by means of the first pump 10 and the air contained in the pump cylinder 22 has been expelled as a flow compressed air via air duct 32 to the orifice exit 31.
- the second pump 20 preferably includes air intake means 25.
- These air intake means 25 can for example be made in the form of a valve 25 adapted to open when pressure is created in the cylinder pump 22 under the effect of the return of the actuating member 30 towards its rest position.
- the valve 25 closes to prevent an escape of the air contained in the pump cylinder 22 outside of it, and the valve 33 opens to allow distribution of the compressed air flow towards the orifice outlet 31.
- the valve 33 closes and the valve 25 opens to allow air to be taken up into the pump cylinder 22.
- the piston 21 of the second pump 20 is fixedly mounted around the fixing member 11 of the first pump 10.
- the piston 21 is independent of the pump body of the first pump 10 so that it is possible to provide a pump 10 of the standard type which does not require specific layout to enable a biphasic type device as described in the present invention.
- said piston 21 of the second pump 20 is an integral part of a ring 15 fixedly mounted around the fixing member 11.
- This ring 15 comprises advantageously fixing means, such as means latching 16, for latching around the member 11 of the first pump 10.
- the piston 21 is formed by a lip 21 which slides tightly in the pump cylinder 22 between the rest and actuation positions of the organ actuator 30, said lip being disposed at the radial end of the ring 15.
- the ring 15 further comprises air intake means 25.
- these air intake means can by example be made in the form of a valve comprising a ball, or the like.
- the piston 21 is formed by a flexible ring and deformable 21a which is integral with the ring 15.
- This ring 21a slides tightly in the cylinder of pump 22 formed in the actuating member 30 when it is moved from its rest position to its actuation position and, unlike piston 21 of the first embodiment, said ring 21a is adapted to deform when the actuator 30 is brought back towards its rest position, to allow recovery 25 in the pump cylinder 22. In this case, the presence of a valve is not necessary in the ring 15.
- Figures 3 to 6 show more detailed the air duct 32 and the valve 33 adapted to the transmission of compressed air flow from cylinder pump 22 to the outlet port 31.
- the member actuator 30 includes a nozzle 38 adapted to spray the product expelled by the first pump 10.
- This nozzle 38 preferably includes an expulsion chamber 35 connected to the outlet port 31, to the first pump 10, and to the second pump 20 via the air duct 32.
- an insert 39 is placed adjacent to said nozzle 38, said insert 39 comprising means such as a groove 32 for forming said conduit of air which opens into the pump cylinder 22 through a orifice formed in said actuating member.
- the compressed air flow coming from the second pump 20 and the dose of product from the first pump 10 is advantageously mixing in the expulsion chamber 35 of the nozzle 38 and are then sprayed through the orifice outlet 31.
- said nozzle 38 can include all appropriate means to guarantee good spraying of the product, in particular means for swirl of it before are expulsion through the outlet port 31.
- the insert 39 fixed in the actuating member 30 of adjacent to the nozzle 38, advantageously incorporates the valve 33.
- this valve 33 can be formed by a flexible tongue stressed in the resting state in a position where it closes the air duct 32, an overpressure created in the pump cylinder 22 above a predetermined level releasing said air duct 32 by deforming said tab 33.
- We can therefore determine the characteristics compressed air flow with the choice of tongue 33 (flexibility, material, etc.).
- the actuator 30 may further include means 37 arranged inside said member 30 to configure the pump cylinder so that when the actuator 30 is in its actuation position, the volume of said cylinder of pump 22 is approximately zero.
- a spraying device of the type biphasic, object of the present invention described above with reference to Figures 3 to 7, can be realized with a minimum of modification compared to a conventional spraying device, say not having the second pump creating the compressed air flow.
- the ring 15 supporting the piston 21 and slightly modify the actuator 30 to y providing said conduit 32 and said valve 33 to obtain all the advantages of the biphasic device. These modifications being very small they can be carried out at low cost.
- the ring 15 and the actuating member 30 can be assembled at the end of assembly, so that the invention does not does not require a specific assembly line.
- the causes the ring carrying the piston 21 of the second pump 20 is arranged around the fixing member 11 of the first pump 10 on the container, does not increase the pump height and therefore the volume of the device as a whole.
