Definitions

  • the invention relates to a diffuser for a pressure vessel provided with a valve, according to the preamble of claim 1.
  • the finger cot may be an integral part of the base body to which it is connected by a tab. It can also be a separate part which can be pressed either in a vertical translation movement, or in a tilting movement around a support.
  • the outlet duct is molded either directly on the interior face of the finger cot, or on a fixing ring used to fix the diffuser on the pressure vessel.
  • the outlet conduit must be made of a material compatible with the product contained in the pressure vessel. It is therefore not only the outlet conduit which is made of this material, but the entire finger cot or the entire fixing ring. The choice of material for the finger cot or the fixing ring is rather dictated by the mechanical properties that these parts must have.
  • the objective of the invention is to propose a diffuser in which the choice of the material of the outlet duct and that of the base body are dictated only by the properties sought for each of them, the diffuser must also be economical to make.
  • the material used for the base body and the material used for the outlet duct are of different compositions and/or different colors. It is thus possible to limit the use of a material compatible with the product contained in the pressure vessel to only the outlet conduit, a relatively small part, while the material for the base body will be chosen for its mechanical properties, its lower cost, its aesthetics, etc.
  • the mechanical hooking means consist of a hooking pin placed on the outlet conduit, and a hooking hole made in the wall of the base body opening into the cavity.
  • the hanging hole is a through hole.
  • the hooking pin is placed on the outlet conduit and the hooking hole is made in the base body, preferably in the finger cot.
  • the hooking pin may comprise a cap connected to the outlet conduit by a rod which ends opposite the cap by a shoulder.
  • the hooking hole is preferably a hole passing through the wall of the base body and comprises at least a first part, called the interior part, whose greatest transverse extension is less than the greatest transverse extension of the cap of the hooking pin , the length of the rod of the tenon being chosen such that in the hooked state of the outlet conduit, the wall of the base body at the edge of the hooking hole is between the cap and the shoulder, the section cross section of the cap and the cross section of the interior part being chosen such that when hooking the outlet conduit onto the base body, the cap can be forcefully introduced into the interior part of the hooking hole without risking damage the outlet duct or the base body.
  • the cap Due to its greater transverse extension, the cap can only pass through the first part of the hooking hole by force, both in the direction of hooking and in the other direction. In other words, after being hooked, the outlet duct cannot unhook itself.
  • the hooking means are designed such that the entire cross section of the cap is larger than the cross section of the first part of the hooking hole.
  • the interior part of the hanging hole continues with a second part, called the exterior part, the interior part opening into the cavity of the base body and the exterior part opening outside the base body, the section transversal of the external part being dimensioned to contain the cross section of the cap of the hooking tenon.
  • the length of the outer part of the hooking hole is preferably substantially identical to the height of the cap so that it is flush with the outer face of the basic body.
  • the outlet conduit comprises a first substantially rectilinear section and a second section, the first section starting at the first end of the outlet conduit and ending at the junction with the second section .
  • the hooking pin is placed at the top of the first section, opposite the first end, or on the second section. The hooking opening is made in the finger cot.
  • the anti-rotation means consist of a tight fit of the hooking pin in the hooking hole.
  • the greatest transverse extension of the hooking pin, in particular of the rod of the hooking pin can be greater than the greatest transverse extension of at least part of the hooking hole, in particular of the part inside the hanging hole.
  • the cross section of the rod can be greater than the cross section of the hanging hole, in particular of the lower part. In this case, the hooking pin has forced its way into the hooking hole.
  • the anti-rotation means consist of an interlocking shape of the hooking pin in the hooking hole.
  • the rod of the hooking pin can fit into the interior part of the hooking hole.
  • the cross section of the hooking pin, in particular of the rod of the hooking pin, and the cross section of the hooking hole, in particular of the interior part of the hooking hole are not no symmetry of revolution.
  • a second solution consists of producing the anti-rotation means in the form of an interlocking shape of the cap of the hooking pin in the exterior part of the hooking hole.
  • the cross section of the cap of the hooking tenon and the cross section of the external part of the hooking hole are not rotationally symmetrical.
  • a simple solution is to design the cross section of the shank of the hooking pin and that of the inner part of the hooking hole, or the cross section of the cap of the hooking pin and that of the outer part of the hooking hole hooking, so that they are complementary.
  • it is not essential that the shapes be complementary for example we can choose a hexagonal section for the hanging hole and a triangular section for the hanging rod or the cap, the angles of the triangle then being in correspondence with every other angle of the hanging hole. More generally, it is sufficient for the cross section of the exterior part of the hooking hole to be circumscribed to the cross section of the cap.
  • the anti-rotation means are constituted by two guide tabs placed in the cavity of the base body and which surround a part of the outlet conduit preventing the latter from pivoting around the hooking pin.
  • the material used for the base body and the material used for the outlet duct may be of different compositions and/or different colors.
  • the hooking hole is through, and the end of the hooking pin opposite the rest of the outlet conduit, in particular the cap, has a particular shape and/or color which, in the hooked state of the outlet duct, is/are visible and recognizable from outside the diffuser and constitute(s) means of identification or information for the user.
  • the basic body is preferably provided with fixing means for fixing it directly or via a ferrule to a pressure vessel.
  • An orifice is generally made in the wall of the base body, facing the second end of the outlet conduit and at a distance from the hanging hole.
  • the orifice can be placed in a recess in the wall of the base body. This recess, considered from outside the base body, is preferably concave in shape.
  • At least part of the base body and/or at least part of the outlet conduit is/are made from a recycled material, from a biodegradable material, from a compostable material or from a biomaterial, or a mixture of these.
  • the outlet conduit may be made of a food grade and/or cosmetic grade and/or pharmaceutical grade and/or medical grade material. This means that the material used complies with current standards concerning materials intended to be in contact with food, cosmetic, pharmaceutical or medical products.
  • the outlet conduit is made of a virgin material and the main body is made at least partly of a recycled material.
  • the invention relates to a diffuser (1) for pressure containers, in particular for aerosol generators, foam generators, dispensing systems for gels, creams, pasty or liquid products. It is intended to activate the valve of the container with a view to taking at least part of the contents of the container and distributing it, for example in the form of an aerosol or foam.
  • Pressure vessels generally consist of a housing fitted with a neck closed by a valve mounted on a valve cup. Sometimes the valve cup is attached to the housing via a dome. When the valve is male type, a nozzle (stem) protrudes from the valve.
  • the diffuser comprises a base body (10) provided with a finger cot (11), and an outlet conduit (20) located inside the base body.
  • the finger cot (11) serves as a push button to move the outlet conduit (20) towards the aerosol generator in view to activate its valve.
  • the outlet conduit (20) and the base body (10) are two separate parts, the outlet conduit being configured to be fixed by hooking means to the base body.
  • the diffuser has a certain rotation geometry around a main axis (A).
  • the adjectives “radial” and “axial” refer to this main axis.
  • this main axis (A) is aligned with the stem of the valve, or more generally with the main axis of the valve body.
  • the basic body is formed of a concave wall forming a cavity. Subsequently, the terms “interior” and “exterior” respectively qualify the elements which are in or towards the cavity and those which are outside or away from the cavity.
  • the outlet conduit (20) has a first end (21) configured to cooperate with the valve; For this purpose it is provided at this first end with means for cooperating with the valve. If the valve is a female type valve, the end includes a stem intended to penetrate the valve to actuate it. If the valve is of the male type, the first end (21) is flared to facilitate the introduction of the stem when mounting the diffuser on the pressure vessel.
  • the second end (22) of the outlet conduit opens outwards and can be fitted with a nozzle to improve the quality of the aerosol. If the product does not exit in alignment with the valve, the outlet conduit is divided between at least a first section (23) substantially rectilinear and a second section (24) inclined relative to the first.
  • the first section begins at the first end (21) and ends at the junction with the second section (24), and the second section (24) begins at the junction with the first section (23) and ends at the second end (22).
  • the second section (24) can be provided on the side of the second end with a nozzle housing (241).
  • the second section (24) consists of an internal conduit (242) strictly speaking composing a part of the outlet conduit and which is surrounded by a cylindrical wall (243) at least on the side of the second end (22).
  • the annular space between the inner conduit (242) and the cylindrical wall (243) constitutes the nozzle housing. If the diffuser is not equipped with a nozzle, it is possible to do without the cylindrical wall (243).
  • hooking means are provided, a part of which located on the outlet conduit (20) cooperates with another complementary part made in the base body ( 10).
  • the means for attaching the outlet conduit are constituted by a latching pin (25) intended to latch into a latching opening of the base body constituting the complementary part of the attachment means.
  • the latching pin (25) is placed at the top of the 1st section (23), opposite the first end (21). It is preferably coaxial with the axis (A), but it is not imperative.
  • the latching tenon consists of a substantially cylindrical rod (251) fixed by its first end to the outlet conduit and carrying at its second end a cap (252) of larger cross section.
  • the junction between the rod (251) and the rest of the outlet conduit constitutes a shoulder (253) at a distance from the cap.
  • the tenon is in fact a cylinder in which an annular groove is made.
  • the top of the cylinder constitutes the cap (252), the annular groove forms the rod (251) and the part of the cylinder opposite the cap plays the role of shoulder (253).
  • the base body (10) consists of a concave wall. In this example, it has a general dome shape. It could also be cylindrical.
  • the base body (10) is provided with a fixing ring (12) configured to fix it either directly to the pressure vessel, in particular on the housing or the valve, or by means of a ferrule, particularly in the case of ON/OFF type diffusers.
  • This fixing ring is provided with fixing means such as a series of gadroons (121) distributed regularly over the entire periphery of the fixing ring. These fixing means are intended to cooperate with complementary fixing means made on the housing or the valve of the pressure vessel, or on the ferrule.
  • the gadroons (121) can snap into place behind the rolled edge at the interface between the housing and the valve cup or between the housing and the dome on which the valve cup is fixed.
  • Other means of fixing can be considered, such as a continuous rib, a thread for screwing, an extra thickness of material for welding, glue for bonding, etc.
  • the wall of the base body is pierced with a finger cot opening (13) in which the finger cot (11) is placed.
  • the finger cot is fixed to the rest of the base body by a tab (14) which serves as a hinge so that when pressure is exerted on the finger cot towards the inside of the base body (therefore towards the valve when the diffuser is mounted on the pressure vessel), the finger cot pivots around an axis passing transversely through the tongue.
  • the finger cot (11) and the corresponding opening (13) are placed towards the top of the base body.
  • the projection of the finger cot (11) on a plane perpendicular to the main axis (A) covers at least the projection of the first section (23) of the outlet conduit on said plane perpendicular to the main axis (A). .
  • the finger cot (11) is located above at least the top of the first section (23) of the outlet conduit.
  • An opening (15) is made in the wall of the base body opposite the second end (22) of the outlet conduit.
  • the product taken from the pressure vessel which leaves the outlet conduit through its second end (22) passes through this orifice (15).
  • This orifice is preferably oblong and extends in an axial plane so that the 2nd end (22) of the outlet conduit, when it moves during actuation of the valve, always remains facing the the orifice (15).
  • the second end (22) of the outlet conduit is therefore floating relative to the base body (10) and to the orifice (15) in particular.

  • the top of the cap (252) is not perpendicular to the stem, but slightly inclined to follow the slope of the finger cot at this location.
  • the cap (252) and the interior part (161) of the hooking hole are dimensioned so that the cap can pass by force through the stem portion when mounting the outlet conduit on the base body without requiring a excessive force which could break in particular the hooking pin (25).
