Definitions

  • This invention relates to a device for the delivery of gas-liquid mixtures, particularly in association with a container for containing a liquid product for delivery in the form of a foam or nebulized spray.
  • Such manually-operated devices collect the product from the container and mix it with a gas (usually air) under a positive pressure, thereby generating a foam during the delivery stage.
  • a gas usually air
  • Such devices basically comprise first means for collecting the product from the container and conveying it to a mixing chamber, said first means being operated by means of an actuator in coordination with second means for conveying air entrained from the environment and suitably pressurized to the same mixing chamber.
  • Said first means essentially comprise a hollow body serving as the product suction/compression chamber, in which a first mobile piston is slidingly engaged.
  • the second means comprise a second piston slidingly engaged in an airtight manner inside a hollow body serving as a gas compression chamber, which communicates with the mixing chamber by means of an air intake pipe.
  • Means for facilitating the formation of the foam comprising a filter or porous septum through which the air-product mixture is forced to flow, are installed downstream from the mixing chamber and upstream of the device's outlet.
  • the user takes action on the actuator to load the elastic means and thereby pushes the air under pressure and the product first towards the mixing chamber and then towards the device's outlet.
  • the air and product are first mixed together in the mixing chamber, forming a mixture that increases in volume as it is forced through the filter or porous septum, giving rise to the required foam.
  • the user By releasing the actuator, the user enables the elastic means to restore the device to the initial resting position, ready for a subsequent delivery action.
  • the first drawback of the known devices lies in that the residual liquid component contained in the foam and in the air-liquid mixture that does not reach the device's outlet tends to drop back into the air compression chamber through the air intake pipe.
  • a further correlated drawback lies in that the volume of the residual liquid reaching the air compression chamber progressively shrinks, thus altering both the product-to-air ratio and the performance of the device with each delivery action.
  • the known state of the art has proposed devices with a one-way valve element inserted inside the air intake pipe to prevent the residual fluid product flowing back into the air compression chamber and to enable the passage of the air.
  • Form Document EP126696 A1 a device is known which comprises collection means adapted to collect residual liquid, said collection means comprising a duct formed in the stem of said device.
  • valve element gives rise to a delay in the flow of pressurized air into the mixing chamber due to the valve's inertia.
  • a further drawback consists in that said valve element makes the device less reliable.
  • the purpose of the present invention is to overcome the above drawbacks.
  • a particular object of the invention is to realize a device for the delivery of gas-liquid mixtures, even in the form of a foam or nebulized spray, that presents no variations in the ratio of air to liquid each time the product is delivered.
  • Another object is to realize a device with minimal overall dimensions by comparison with devices of the known state of the art used in comparable working conditions.
  • a further object is to realize a device that comprises a smaller number of components than comparable devices of known type.
  • Another object is to realize a device that is easier to assemble than comparable devices of known type.
  • a further object is to realize a device that can also be assembled using automated production lines.
  • Another object is to realize a device that is more compact than comparable devices of known type.

  • a device for the delivery of gas-liquid mixtures that can be used in association with a container for a liquid in accordance with the content of the main claim.
  • the proposed solution advantageously enables the above-mentioned drawbacks to be overcome without using valve elements, thereby reducing both the cost of the device and its complexity, while increasing its reliability and the simplicity of the assembly operations involved, be they undertaken manually or using automatic equipment.
  • Another advantage of the proposed solution lies in that it enables the realization of a device with minimal overall dimensions, thereby also minimizing the space occupied for the storage of the device-container system and maximizing the amount of product that can be stored inside the container.
  • Position indicators mentioned in the single embodiments are logically transferable to new positions in the event of any change of position.

  • Said nozzle 65 is complete with three lines 66, which carry the air-product mixture towards the outlet 65b of the nozzle 65, generating a turbulence that determines the nebulization of the mixture.
  • FIG. 1 Another embodiment of the invention, indicated globally with the numeral 104 in figure 16 , is distinguishable from the previous embodiments in that the collection means 6 consist of a stretch 70 of the air intake pipe 16 and, to be more precise, of a stretch wherein said pipe has a wider cross-section.

  • the user takes preliminary action on the actuator 13, rotating it in order to configure the device 1 in the required operating mode.
  • the user can lock the device 1 by rotating the spout or cap 13 around its axis 30 so as to bring it into the position shown in detail in figure 4 : in this position, the first opposing elements 29a face the striker planes 31 a, thus preventing any axial movement of the first and second means 2 and 5.
  • the user rotates the actuator 13 around its axis 30 in order to bring it into the position shown in figure 1 : in this position, the former opposing elements 29a face the groove 34, along which they are able to slide freely, thus enabling the pistons 8 and 18 to move axially under the pressure P exerted by the user on the actuator 13.
  • the user loads the elastic means 28 and compresses both the product L contained in the first chamber 9 and the air contained in the second chamber 60.
  • the rise in the pressure in the first chamber moves the plunger 8b on the supporting element 8a, thus enabling the liquid L contained in the chamber 9 to flow out, first into the liquid intake pipe 11 and then into the mixing chamber 3, along the path indicated by the numeral 50 in figure 10 .
  • the increase in the pressure in the second chamber 60 forces the pressurized air first into the air intake pipe 16 and then into the mixing chamber 3, along the path indicated with the numeral 51.
  • the mixture that forms inside the mixing chamber 3 then moves to the outlet 4, passing through the means 20.
  • the liquid-air mixture passes first through the holes 21 in the diaphragm 20b, giving rise to a turbulence that facilitates the creation of air bubbles in the mixture, which subsequently expands in the expansion chamber 22 and passes through the filter 20a, where it becomes finer, ultimately reaching the outlet 4 through the pipe 4a in the form of a foam F, as shown in figures 3 and 11 .
  • This elastic return generates a negative pressure inside the chambers 9 and 60.
  • This negative pressure prompts the intervention of the first and second valve means 14 and 15 and makes the liquid L flow into the first chamber 9, making the device ready for subsequent reuse.
  • the negative pressure retains the first plunger 8b which slides along the supporting element 8a and thus closes the liquid intake pipe 11, as illustrated in detail in figure 12 .
  • the negative pressure generated in the second chamber 60 prompts the intervention of the third valve means 19, which consequently enable air to flow from the outside E into the first chamber 5, preparing the device 1 for subsequent reuse.
  • the residual liquid L thus collects temporarily in the tank 25, advantageously avoiding it reaching the second chamber 60.
  • the proposed solution means that, when the device is subsequently reused, the tank 25 is emptied and all or most of the liquid it contained is carried into the mixing chamber 3. This advantageously enables the recovery of the liquid L in the tank 25, returning it to the mixing chamber 3 and consequently to the device's outlet 4, thereby substantially avoiding any loss of liquid.
  • a subsequent operation of the device determines a flow of pressurized air into the tank 25 through the first stretch of the air intake pipe 16.
  • the proposed solution advantageously enables a device to be obtained that contains a smaller number of valve elements than comparable devices of the known state of the art.
  • the proposed device can advantageously and preferably also be made entirely of plastic or synthetic material. This gives rise to a device that can be completely recycled without any prior action being needed to separate any parts made of metal or other incompatible materials.
  • Another advantage lies in that, by preventing the liquid from reaching the chamber, the proposed solution enables the spring to be advantageously installed inside said compression chamber, a solution that would otherwise not be advisable because of the oxidation phenomena that would be bound to occur therein as a result of contact between the metal, the liquid and the air, leading to a discoloring of the liquid being delivered.
