Definitions
- the invention relates to a diffuser for a pressurized container provided with a valve, in particular for an aerosol generator, which diffuser is provided with a base body formed by a wall having a concave inner face forming a cavity, and having a finger cot intended to be pushed in by the user to actuate the valve, and an outlet duct placed in the cavity of the base body, which duct has a first end provided with means for cooperating with the valve of the container under pressure, and a second end for the outlet of the product contained in the pressure vessel.
- the finger cot can 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 translational movement or in a tilting movement around a support.
- the outlet duct is molded either directly on the inside of the finger cot or on a fixing ring serving to fix the diffuser on the pressure vessel.
- the outlet duct must be made of a material compatible with the product contained in the pressure vessel. It is therefore not only the outlet duct which is made of this material, but the entire finger cot or the entire fixing ring.
- the objective of the invention is to provide 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 also having to be economical to manufacture.
- This objective is achieved owing to the fact that the outlet duct and the base body are two separate parts which, after assembly, are connected together by mechanical coupling means.
- Anti-rotation means may be provided to block the outlet duct from rotating relative to the base body. All kinds of snapping means can be used.
- the material used for the base body and the material used for the outlet duct are of different compositions and / or of different colors. It is thus possible to limit the use of a material compatible with the product contained in the pressure vessel to the single outlet duct, 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 fastening means may consist for example of a fastening pin placed on the outlet duct or in the cavity of the base body, and of a fastening hole made either in the wall of the base body by opening into the cavity or onto the outlet duct.
- the hanging hole is either a blind hole or a through hole.
- the hooking pin can be placed on the outlet duct and the hooking hole can be made in the base body, preferably in the finger cot.
- the hooking lug may include a cap connected to the outlet duct by a rod which ends opposite the cap with 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 inner part, of which the greatest transverse extension is less than the greatest transverse extension of the cap of the catching pin.
- the length of the shank of the tenon being chosen so that in the hooked state of the outlet duct, 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 inner part being chosen such that when hooking the outlet duct to the base body, the cap can be forcefully introduced into the inner part of the hooking hole without risking damage the outlet duct or the base body.
- the hat Because of its greater transverse extension, the hat can only forcefully pass through the first part of the hanging hole, both in the hanging direction and in the other direction. In other words, after being hooked up, the outlet duct cannot come off by itself.
- the hooking means are designed so that the entire cross section of the hat is larger than the cross section of the first part of the hooking hole.
- the inner part of the hooking hole continues with a second part, called the outer part, the inner part opening into the cavity of the base body and the outer part opening out to the outside of the base body , cross section the outer part being dimensioned to contain the cross section of the cap of the hooking stud.
- the length of the outer part of the hooking hole is preferably substantially identical to the height of the cap so that the latter is flush with the outer face. of the base body.
- the outlet duct comprises a first substantially rectilinear section and a second section, the first section starting at the level of the first end of the outlet duct 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 shank of the hooking stud can be greater than the greatest transverse extension of at least part of the hooking hole, in particular of the part. inside the hooking hole.
- the cross section of the rod may be greater than the cross section of the hooking hole, in particular of the lower part. In this case, the hook pin has forced its way into the hook hole.
- the anti-rotation means are constituted by an interlocking of shapes of the hooking pin in the hooking hole.
- the shank of the hooking stud can fit into the inner part of the hooking hole.
- the cross section of the hooking pin, in particular the rod of the hooking pin, and the cross section of the hooking hole, in particular the inner part of the hooking hole must not be no symmetry of revolution.
- a second solution consists in making the anti-rotation means in the form of an interlocking of the cap shapes of the catching pin in the outer part of the catching hole.
- the cross section of the catch lug cap and the cross section of the outside of the snap hole are not of rotational symmetry.
- 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 post and that of the outer part of the hooking hole, so that they are complementary. It is possible for example to choose two square sections, or more generally polyhedral sections. However, it is not essential that the forms are complementary, we can for example choose a hexagonal section for the hooking hole and a triangular section for the hooking rod or the cap, the angles of the triangle then being in correspondence with every other angle of the hooking hole . More generally, it suffices for the cross section of the outer part of the hooking hole to be circumscribed to the cross section of the cap.
- the anti-rotation means consist of two guide tabs placed in the cavity of the base body and which surround a part of the outlet duct while preventing the latter from pivoting around the catching pin.
- the material used for the base body and the material used for the outlet duct can be of different compositions and / or of different colors.
- the hooking hole is through, and the end of the hooking pin opposite the rest of the outlet duct, 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 the outside of the diffuser and constitute (s) means of identification or information for the user.
- the base body is preferably provided with fixing means for fixing it directly or through 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 duct and away from the hooking hole.
- the orifice can be placed in a recess in the wall of the base body. This recess, viewed 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 duct is / are made in a recycled material, in a biodegradable material, in a compostable material or in a biomaterial , or a mixture of these.
- the basic body can be made of a material chosen from
- polymer material in particular polyethylene (PE), polypropylene (PP), polylactic acid (PLA), polyhydroxyalkanoates (PHA), poly (butylene succinate) (PBS), or a mixture of these, which polymer may contain mineral fillers, in particular glass and / or basalt, and / or be reinforced with mineral or vegetable fibers,

- PLA polylactic acid
- PHA polyhydroxyalkanoates
- PBS poly (butylene succinate)
- mineral fillers in particular glass and / or basalt, and / or be reinforced with mineral or vegetable fibers
- lignin-based material preferably cardboard and / or wood
- the outlet duct can be made of a material of food grade and / or of cosmetic grade and / or of pharmaceutical grade and / or of medical grade. It should be understood by this that the material used complies with the standards in force concerning materials intended to be in contact with food, cosmetic, pharmaceutical or medical products.
- the outlet duct can be made of a material chosen from:
- PE polyethylene

- POM polyoxymethylene
- PBT poly (butylene terephthalate)
- PA polyamide
- - a metal preferably aluminum or steel, especially stainless steel.

- the invention relates to a diffuser (1) for pressurized containers, in particular for aerosol generators, foam generators, distribution systems for gels, creams, pasty or liquid products, etc. It is intended to actuate the valve of the container with a view to removing at least part of the contents of the container and to distribute it for example in the form of an aerosol or a foam.
- Pressure vessels generally consist of a housing provided 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, a nozzle (stem) protrudes from the valve.
- the diffuser comprises a base body (10) provided with a finger cot (1 1), and an outlet duct (20) located inside the base body.
- the finger cot (11) serves as a push button to move the outlet duct (20) towards the aerosol generator in order to actuate its valve.
- the outlet duct (20) and the base body (10) are two separate parts, the outlet duct being configured to be fixed by hooking means to the base body.
- the diffuser has a certain geometry of rotation about 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 base body is formed by a concave wall forming a cavity.
- the terms “inside” and “outside” respectively qualify the elements which are in or towards the cavity and those which are outside or separated from the cavity.
- the outlet duct (20) has a first end (21) configured to cooperate with the valve; it is therefore 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 enter 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 duct 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 duct is divided between at least a first section (23) which is 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 duct (242), strictly speaking, forming part of the outlet duct and which is surrounded by a cylindrical wall (243) at least on the side of the outlet. second end (22).
- the annular space between the inner duct (242) and the cylindrical wall (243) constitutes the housing of nozzle. If the diffuser is not fitted with a nozzle, the cylindrical wall (243) can be omitted.
- the attachment means of the outlet duct consist of a latching pin (25) intended to engage in 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 pin consists of a substantially cylindrical rod (251) fixed by its first end to the outlet duct 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 duct 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 acts as a shoulder (253).
- the base body (10) consists of a concave wall. In the present example, it has the general shape of a dome. 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, in particular 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 produced on the housing or the valve of the pressure vessel, or on the ferrule.
- the gadroons (121) can snap behind the rolled edge at the interface between the housing and the valve cup or between the housing and the dome to which the valve cup is attached.
- Other fastening means can be considered, such as a continuous rib, a thread for screwing, an extra thickness of material for welding, glue for gluing, etc.
- the wall of the base body is pierced with a finger cot opening (13) in which the finger cot (11) takes place.
- the finger cot is fixed to the rest of the base body by a tab (14) which acts 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 transversely passing 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 (1 1) on a plane perpendicular to the main axis (A) covers at least the projection of the first section (23) of the outlet duct 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 duct.
- An orifice (15) is made in the wall of the base body opposite the second end (22) of the outlet duct.
- the product taken from the pressure vessel which leaves the outlet duct through its second end (22) passes through this orifice (15).
- This orifice is preferably oblong and extends in an axial plane so that the 2 nd end (22) of the outlet duct, when it moves during the actuation of the valve, always remains opposite the orifice. (15).
- the second end (22) of the outlet duct is therefore floating relative to the base body (10) and to the orifice (15) in particular.
- a hooking hole (16) is made in the base body (10) to secure the outlet duct (20).
- This hole constitutes the additional attachment means for fixing the outlet duct (20) to the base body (10).
- the hooking hole (16) is intended to receive and retain the hooking pin (15) of the outlet duct. It passes right through the wall of the base body. In the example shown here, it is divided into two parts: an inner part (161) located towards the inside of the base body and an outer part (162) opening onto the outer face of the finger cot (1 1).
- the inner part (161) is sized to receive the rod
- the outer part (162) and the cap are preferably sized so that the top of the cap is flush with the outer face of the finger cot (11) and is in its continuity.
- the length of the outer part (162) of the hooking hole is preferably substantially the same as the height (measured between the junction of the cap with the stem and the top of the cap opposite the stem) of the cap
- the top of the cap (252) is not perpendicular to the rod, but slightly inclined to follow the slope of the finger cot at this location.
- the cap (252) and the inner part (161) of the hooking hole are sized so that the cap can forcefully pass through the stem part when mounting the outlet duct to the base body without requiring any too great a force which could break in particular the fastening pin (25).
- the cross section of the cap (252) is greater than the cross section of the interior part (161) of the hooking hole. More generally, it is sufficient that the greatest transverse extension of the cross section of the cap is greater than the greatest transverse extension of the cross section of the interior part of the hooking hole.
- the cap Once the cap has passed forcibly through the inner part (161) of the hooking hole, it cannot pass again by itself, that is to say without external force, in the other direction through this interior part.
- no particular force is exerted on the outlet duct which could tend to bring out the hooking pin from the hooking hole.
- the attachment by means of the latching of the tenon in the attachment hole is therefore very well suited to a diffuser.
- anti-rotation means can be provided.
- these anti-rotation means consist of two guide tabs (17). These guide tabs are located on the inner face of the base body, in this example on the inner face of the finger cot (11), between the hooking hole (16) and the product outlet (15).
- the edge of the finger cot opening (13) can be continued by a skirt (131) directed towards the center, which skirt also serves as a cover when the finger cot (11) is pressed.
- the perimeter of the finger cot has a skirt (1 12) directed inward. Stop ribs (18) can also be provided in the base body cavity to limit the sinking of the diffuser on the housing of the pressure vessel.
- the outlet orifice (15) is placed in a recess (151) of the wall of the base body, which recess is more or less deformed, in particular concave considered from the outside of the base body, depending on the length of the second section (24) of the outlet duct.
- the outlet duct (20) is introduced into the cavity of the base body (10), with its second end (22) directed towards the outlet orifice (15).
- the hooking pin (25) is inserted into the hooking hole (16).
- the cap (252) forcibly passes through the inner part (161) until it emerges into the outer part (162), the cross section of which is sufficient to receive it.
- the rod (251) of the hooking pin is placed in the inner part (161) of the hooking hole and the shoulder (253) opposite the cap is in contact, or almost in contact, with the inner face of the finger cot (11).
- the second section (24) of the outlet duct passes between the two guide tabs (17) which by their shape guide the outlet duct exactly in the alignment of the outlet (15).
- outlet duct is retained on the one hand in axial translation by the blocking of the wall of the finger cot at the level of the attachment hole between the cap (252) and the shoulder (253), and on the other hand by rotation by locking the second section (24) between the two guide tabs (17).
- the cap (252) of the hooking tenon of the outlet duct can blend into these reliefs for a more aesthetic effect.
- the cap (252) is shorter than the outer part (162) of the hanging hole, so that it is not flush with the outer face of the finger cot and forms a hole similar to other reliefs.
- the shape of the cap (252) of the fastening pin may be non-circular, therefore without symmetry of revolution. If the shape of the outer part (162) is complementary and adjusted to that of the bonnet, it is even possible to dispense with the guide tabs (17) since the outlet duct is blocked in rotation by the non-shaped interlocking of the bonnet. circular in the upper part of complementary shape.
- the non-circular shape of these two parts and their at least partial adjustment constitute anti-rotation means.
- the outer part (162) of the hooking hole does not necessarily have the same shape as the cap (252) of the hooking pin. It is sufficient that the cap can be accommodated therein, even by protruding or being set back from the outer face of the base body and even not blocked in rotation since the guide tabs, or a tight fit or the interlocking form of the rod (251) in the inner part (161) of the hooking hole, make it possible to block the rotation of the outlet duct.
- the fastening pin can only consist of a rod penetrating by force into a corresponding hole in the base body. This hole does not need to be through, a blind hole may be sufficient if the thickness of the base body at this location is thick enough. Here too, it is possible to dispense with the guide tabs since the tight fit of the rod is sufficient to block the outlet duct from rotating. If the hanging hole is through, the shape or color of the hanging rod, or at least of its free end, can also serve as an indication as will be explained below.
- the free end of the post of the post has a particular shape, for example a triangle, a star, etc., and that the outer part (162) of the hooking hole has a complementary shape.
- the cross section of the free end of the rod can be identical to that of the rest of the rod (round for example) or be smaller or at least be inscribed in the cross section of the rest of the rod.
- the tight fit of the tenon in the hole can be limited to the inner part (162) or the outer part (162) of the hooking hole.
- the outlet duct can be attached to another part of the base body (10), in particular in the longitudinal plane passing through the main axis (A) and the center of the product outlet (15).
- provision can be made to fix it between the fixing ring (12) and the product outlet (15), or on the contrary opposite to the product outlet (15).
- a bearing surface can be provided at the top of the outlet duct on which the finger cot (1 1) rests when the user pushes it in to actuate the valve.
- the outlet duct (20) can be fixed to the base body by any other means of mechanical attachment.
- slots can be provided on the inside of the base body in which the side edges of the cap (252) can slide to the desired position where they can snap into place or be held in place due to the narrowness. slits there. It is also possible to provide latching lugs on one of the parts and complementary latching slots on the other part.
- the invention makes it possible to focus particularly on the outlet duct (20), which is essential for the quality of the spray, the rest of the diffuser, namely the base body, being only a covering. It is possible to have very short channels, which is favorable especially when using compressed gases.
- the base body and the outlet duct can be manufactured in different factories, which limits the problems associated with transportation.
- the same outlet duct can be used with basic bodies of different color and / or material, and the same basic body can be used with outlet ducts of different qualities. Many combinations are therefore possible.
- the invention it is possible to use two different materials for the outlet duct (20) and for the base body (10).
- the material of the outlet duct will be chosen to be compatible with the product to be sampled, while the material of the base body will not need to fulfill this condition, but may be chosen for its mechanical properties in particular.
- the material of the outlet duct will need to be food grade, while that of the base body will not need to be and may be more economical.
- mechanical attachment means in particular by snap-fastening, it is not necessary for the two materials to be compatible with each other. It is also not necessary to provide a bi-material injection.
- polymer materials whether they are virgin or recycled, derived from petroleum or natural resources, biodegradable or not, or even compostable or no. They may contain mineral fillers (glass, basalt, etc.), be reinforced with mineral or vegetable fibers. It is also possible to envisage non-polymeric materials, such as lignin-based materials (cardboard, wood), materials containing textiles, metals, etc.
- non-polymeric materials such as lignin-based materials (cardboard, wood), materials containing textiles, metals, etc.
- polymers PE, PP, POM, PBT, PA, etc.
- metals aluminum, steel, in particular stainless steel.
- the end of the rod, in particular the cap, and / or the hooking hole can be configured to transmit information to the user.
- the color and / or the shape of the end of the rod, and in particular of the cap (252) can serve as information for the user, and in particular as a means of identification.
- the two materials is a biomaterial or a recycled material
- a manufacturer will thus be able to communicate to his customers on his strategic desire to be part of a sustainable development policy.
- outlet ducts To facilitate the handling of the outlet ducts, they can be fitted with assembly fins (244), in particular on the second section (24), which make it possible to correctly guide the outlet ducts in the assembly machine .
- the hooking pin may be at a certain distance from the junction between the first section (23) and the second section (24) of the outlet duct, it is preferable to provide a recess (26) in the material located between this junction and the hooking pin.
- the shoulder (253) of the hooking pin is placed on the top wall of this recess.
