Definitions

  • the invention relates to a two-piece nozzle for an aerosol dispenser.
  • a diffuser is placed at the valve outlet, which serves on the one hand to actuate the valve and on the other hand to direct the jet in a predefined direction.
  • the diffuser is equipped with a conduit leading from the valve stem to an outlet orifice.
  • a nozzle is generally placed at the outlet of the conduit. This nozzle traditionally consists of a cup-shaped insert with a small central orifice in its base and fitted onto a stud made in the diffuser, at the end of the conduit.
  • the diffuser conduit ends with one or more longitudinal channels distributed around the circumference of the stud.
  • Another solution is to place a two-piece nozzle in a cavity made at the end of the diffuser duct, namely an inner part fulfilling the function of the diffuser tenon and an outer part similar to the insert.
  • the longitudinal channels are then placed either on the inner part or on the outer part.
  • Such a two-piece nozzle is known, for example, from US 9,527,092 B2 or the document WO 03/061839 A1 .
  • converging channels are placed in the bottom of the insert or on the front face of the tenon or inner part, opening tangentially into a circular or annular turbulence chamber surrounding the outlet orifice. This is called a swirl nozzle (mechanical break-up or MBU).
  • the determining factors for spray quality include the geometry and distribution of the channels, the diameter of the outlet orifice and the conical shape of the outlet orifice.
  • current injection techniques for inserts do not reliably produce outlet orifices with diameters less than 0.2 mm.
  • the objective of the invention is therefore to improve the two-piece nozzles of the state of the art.
  • the channels are divided into lateral channels made in the lateral face of the inner part and/or in the inner face of the tubular wall of the outer part, and into converging channels made in the front wall of the outer part or in the front face of the inner part.
  • the cross-section of the lateral channels decreases between the upstream end of the channels, located opposite the front face or the front wall, and the downstream end of the channels, located on the side of the front face or the front wall.
  • the lateral channels may have a bottom wall surrounded by two side walls, the side walls approaching each other in the direction of the front face of the inner part or the front wall of the outer part. It is also possible for the bottom wall to approach the inner face of the tubular wall of the outer part, when the lateral channels are placed on the outer part, or the lateral face of the inner part, when the lateral channels are placed on the inner part.
  • the side channels have a bottom wall surrounded by two side walls, the intersection between each side wall and the bottom wall forming a non-right angle, the two walls sloping relative to the bottom wall preferably in the same direction, the two walls preferably being inclined at the same angle and/or the two walls preferably extending parallel to each other.
  • the front face of the inner part is free of projection, or the front face of the inner part has a projection, the end of which does not penetrate into the outlet opening.
  • the cavity of the outer part and the inner part preferably have the shape of a cylinder of revolution or a cone of revolution around the axis of symmetry. It goes without saying that it would also be possible to provide other shapes, in particular a cylinder or a cone with a polygonal base. Similarly, it would be possible for the front face of the inner part and/or that of the front wall of the outer part to be curved, for example hemispherical.
  • the side channels may be substantially straight and parallel to an axial plane passing through them defined by a main axis passing through the center of the nozzle.
  • the length of the channels is the shortest. It is also possible for the channels not to be straight and to diverge from an axial plane defined by the main axis passing through the center of the nozzle.
  • the side channels may be helical in shape. This latter shape is particularly simple to achieve on the inner part. In such a case, the channels are longer. Changing the length of the side channels allows the flow rate of the material stream to be adapted.
  • the converging channels may extend from the envelope defining the side face of the inner part or the internal face of the tubular wall of the outer part towards the turbulence chamber into which they preferably open tangentially.
  • the inner part has a rear face, preferably substantially flat, provided with a peripheral edge projecting in the direction opposite to the front face, one or more passages being made in the peripheral edge to bring the inner face and the outer face of said peripheral edge into contact.
  • the passages passing through the projecting edge preferably open into said lateral channels.
  • the nozzle may be immobilized in the cavity, in particular to ensure exact alignment of the lateral channels and the converging channels.
  • the nozzle may be provided with fixing means for fixing the inner part in the cavity of the outer part so that it is immobilized in the cavity.
  • Another solution is to dimension the inner part so that it is retained by clamping in the cavity of the outer part so that it is immobilized there.
  • the inner part and/or the outer part may be provided with first orientation means for orienting the inner part relative to the outer part in order to align the channels with each other.
  • Another solution is to orient the inner part before transferring it into the cavity of the outer part.
  • the inner part may be able to rotate in the outer part.
  • the nozzle may be provided with retaining means for retaining the inner part in the cavity of the outer part so that it is rotatable in the cavity around the axis of symmetry.
  • the diffuser duct When the nozzle is to be used with two-way valves, provision may be made for the diffuser duct to extend the separation of the two ways to its outlet end and for part of the nozzle channels to be intended for one of the ways and the rest of the channels for the other way. In this case, it is preferable to provide the nozzle with second orientation means to orient the nozzle relative to the diffuser for which it is intended.
  • Another solution consists of separating the channels sufficiently from each other, or giving them a sufficiently small angular deployment, so that the same duct cannot be in contact simultaneously with both ways.
  • the nozzle of the invention may be sold alone or be mounted in a housing of an aerosol diffuser, the housing being able to have a bottom face provided with diverging channels.
  • the invention relates to a nozzle (1, 2) for an aerosol dispenser to be placed on a valve of a pressurized container.
  • the nozzle can also be used with an aerosol dispenser cooperating with a container that is not pressurized.
  • the nozzle consists of an inner part (11, 21) and an outer part (12, 22). Two examples of nozzles are shown in the figures. The constituent elements of variants are indicated by a "'" sign.
  • the nozzle and its components have a certain rotational symmetry around a principal axis (A) passing through the nozzle parallel to the general direction of diffusion of the product. It will be seen that this rotational symmetry is not absolute, certain parts of the nozzle deviating from it.
  • the adjectives "axial” or “radial” relate to this principal axis and define an element parallel to the axis or perpendicular to this axis respectively.
  • spatial references such as “upper” and “lower”, “above” or “below” refer to the nozzle and its components as represented for example on the Fig. 6 or the Fig. 18 for example. This is not an absolute position, but only a reference position for the description, the nozzle integrated in a diffuser can be used in any position suitable for the product to be delivered.
  • the outer part (12, 22) has the general shape of a bucket formed by a tubular wall (121, 221) open on one side and closed on the other by a front wall (122, 222).
  • the cavity defined by the tubular wall and the front wall has the general shape of a cylinder of revolution or a cone of revolution.
  • An outlet opening (123, 223) is made in the center of the front wall to bring the cavity into contact with the external face of the front wall.
  • the inner part (11, 21) has the general shape of a cylinder of revolution or a cone of revolution essentially complementary to that of the cavity of the outer part. It has a front face (111, 211) which, in the mounted state of the nozzle, is opposite the wall front (122, 222) of the outer part, generally being partially in contact with it.
  • the front face (111, 211) is free of projection. It is preferably smooth or substantially smooth. A projection could be provided, but this does not penetrate into the outlet orifice (123, 223).
  • the inner part has a substantially flat rear face (115, 215). It is provided with a peripheral edge (115a) projecting in the opposite direction to the front face (111). One or more passages (115b) are provided in the peripheral edge to bring the inner face and the outer face of said peripheral edge into contact. These passages (115b) open into the lateral channels (112) when said lateral channels are made in the side wall of the inner part. This is the case of the 1st nozzle, as is clearly visible in the Fig. 2 notably.
  • Channels are provided in the inner part and/or in the outer part to bring the product to be diffused coming from the valve to the outlet opening (123, 223) of the nozzle.
  • These channels are divided into two parts: lateral channels (112, 112', 224) leading from the nozzle inlet to the front wall and converging channels (125, 225) leading from the end of the lateral channels (112, 224) to a turbulence chamber (127, 227) from which the outlet opening (123, 223) starts.
  • the lateral channels can be provided on the cylindrical or frustoconical wall of the inner part (11) as in the first nozzle or on the internal face of the tubular wall (221) of the outer part as in the second nozzle.
  • the converging channels (125, 225) are made in the bottom of the bucket, on the internal face of the front wall (122, 222) of the outer part. It would however be possible to make them on the front face (111, 211) of the inner part (11, 21).
  • the converging channels are used to form the spray. These channels start from the peripheral edge of the front wall (122, 222) of the cavity of the outer part or from the front face (111, 211) of the inner part, and open tangentially, or at least non-radially, into a circular cavity so that when the two parts are assembled, a turbulence chamber (127, 227) is formed, promoting the formation of the spray. This is the process known as "mechanical break-up".
  • the outlet opening (223, 223') is always located downstream of the central swirl chamber (227, 227') and, when placed on the axis of symmetry (A), behind the swirl chamber in the direction of flow of the product, but it does not start necessarily closer to the external face of the front wall (222) than certain parts of the converging channels.
  • the outlet opening can be surrounded in its lower part by at least part of the converging channels without them however opening into this outlet opening. This is clearly visible for example on the section of the Fig. 18 .
  • the side channels (112, 224) may be vertical, as in the exemplary embodiments presented in Fig. 1 And Fig. 8 .
  • the channels are straight and extend parallel to an axial plane passing through them defined by the axis of symmetry (A). They define the shortest path between the nozzle inlet and the converging channels. It is also possible to make them with a geometry that deviates from the vertical. For example, they can be helical in shape as in the Fig. 20 , or even zigzag.
  • the lateral channels (112') do not extend parallel to an axial plane defined by the axis of symmetry (A), but diverge from this axial plane. This makes it possible to lengthen the channels while maintaining the same height for the nozzle.
  • the shorter the channel the greater the flow rate.
  • By moving the lateral channels away from the vertical their length is increased, which makes it possible to adapt the flow rate to specific needs while maintaining the same size for the nozzle.
  • the side channels are placed on the inner part (11).
  • the cross-section of these side channels decreases slightly between the inlet located at the lower face (115) and the outlet located at the front face (111).
  • the side channels (112, 112', 224) may have a bottom wall (112a) surrounded by two side walls (112b).
  • To reduce the cross-section of the side channels it is possible, for example, to bring the side walls (112b) closer to each other in the direction of the front wall (122, 222) or the front face (111, 211).
  • the two side walls (112b) of the side channels can be inclined relative to the bottom wall (112a), preferably in the same direction, generally at the same angle. This is clearly visible on the Fig. 3 in particular. It would also be possible that the two side walls (112b) extend parallel to each other.
  • the side channels (224) of the 2nd nozzle are placed on the inner face of the tubular wall (221) of the outer part. They also have a cross section which decreases due to a slight inclination of the side walls and the bottom wall of the channels. In other words, the closer the side channels get to the front wall (122, 222), the closer the side walls get to each other.
  • Another alternative or complementary solution may provide that the closer the side channels get to the front wall (122, 222), the closer the bottom wall (112a) gets to the inner face of the tubular wall (121, 221) of the outer part.
  • each side wall and the bottom wall of the side channels may form a non-right angle, the two walls sloping relative to the bottom wall preferably in the same direction, the two walls preferably being sloping at the same angle. It would also be possible for the two walls to extend parallel to each other.
  • One of the side walls of the lateral channels is rounded and is an extension of the side wall of the converging channels. This rounded shape of the side wall helps guide the flow into the corresponding converging channel.
  • the second side wall of the lateral channels is straight and substantially radial.
  • the converging channels can be placed in the front wall of the cavity of the outer part or on the front face of the inner part.
  • the converging channels of the first set start from the lateral channels and open radially into a first annular cavity from which the channels of the second set start, which open radially into a second circular or annular cavity forming the turbulence chamber (227) and from which the outlet opening (223) starts.
  • the inner part (11) is well oriented with respect to the outer part (12) and that it maintains this orientation throughout the use of the diffuser carrying the nozzle in order to ensure proper operation of the nozzle and to limit the cross-section of the lateral channels (112) at their junction with converging channels.
  • first orientation means such as foolproofers or orientation markers.
  • Another solution consists of correctly orienting the inner part before introducing it into the outer part.
  • the inner part (11) can be slightly oversized compared to the cavity of the outer part (12) so that it is forced in and held in the correct position by clamping. Thanks to this correct orientation of the two parts, it is possible to limit the cross-section of the lateral channels (112) since it is certain that they will open exactly into the inlet of the converging channels (125). It goes without saying that in the second nozzle too, the inner part (21) can be locked in the cavity of the outer part (22) either by orientation means or by clamping or force-fitting, although the question of the alignment of the side channels and the converging channels does not arise.
  • the nozzle is used in a diffuser for a two-way valve.
  • the diffuser duct is designed to maintain the separation of the paths between the outlet of the valve stem and the nozzle.
  • the first path of the valve is brought into contact with a portion of the side channels and the second path with the remainder of the side channels.
  • the mixing of the products then takes place in the turbulence chamber. It is therefore necessary for the nozzle to be correctly oriented in the diffuser. This can be done either by maintaining the initial orientation of the nozzle, for example by keeping it in its molding cavity until it is placed in the diffuser, or by providing orientation means such as polarizing devices.
  • Another solution consists of distributing the inlets of the side channels and/or their angular extent in such a way that, whatever whatever the position of the nozzle, the same side channel cannot be in contact simultaneously with the first channel and with the second channel.
  • the outer part (12, 22) is preferably made of polyacetal such as POM. It can also be made of polyamide or semi-crystalline polyester such as PBT.
  • the inner part (11, 21) is preferably made of polyacetal such as POM. It can also be made of polyamide or semi-crystalline polyester such as PBT. These materials offer the advantage of being fluid and allow the molding of precision parts with good geometric and dimensional stability. In addition, they are rigid, which allows good anchoring of the nozzle in the diffuser via the anchoring means (126, 226) which grip in the softer PP-type material of the diffuser. In addition, in the case where sterilization by ionizing radiation is required for the diffuser equipped with its nozzle, the PBT will have better behavior than the POM or certain PAs.
  • the nozzle of the invention is placed in a housing provided directly at the outlet of the duct.
  • Anchoring means (126, 226) ensure secure attachment of the nozzle to the outlet of the diffuser duct. The nozzle thus retained cannot be ejected, even when the pressure inside the duct is high and the valve is open. If necessary, the bottom of the housing can have diverging channels opening into the lateral channels of the nozzle.
