Definitions
- the invention relates to a diffuser for a pressure vessel, the diffuser being provided with an outlet channel opening into a nozzle housing intended to receive and retain a nozzle provided with a retention ring, the nozzle housing comprising a tubular wall which extends around an axis and which is open outwards at its end opposite the outlet channel.
- the nozzle generally consists of a cylindrical wall closed on one side by a front wall with an outlet and open on the other. It bears a retention ring on the external face of the cylindrical wall.
- the retainer ring forms a "hard tooth” that snaps into the softer material of the nozzle housing.
- This hooking system also provides a seal between the nozzle and the nozzle housing.
- the objective of the invention is therefore to modify the retention mode of the nozzle so that it withstands higher pressures, and in particular that it withstands at least 20 bars.
- the tubular wall of the nozzle housing is provided, at a distance from its open end towards the outside, with a bearing surface which extends over at least part of its periphery. and behind which can engage at least part of the retention ring of a nozzle introduced into the nozzle housing.
- the invention provides positive grip due to the fact that the retaining ring, playing the role of a hook, is positioned behind the bearing surface against which it rests. The nozzle is blocked in a much more efficient way than by the retention by traditional deformation, even if this snap-in is not done all around the nozzle housing.
- the advantage of the invention lies in particular in the fact that it is possible to use common nozzles. It is not necessary to have specific nozzles for this type of diffuser.
- the bearing surface is preferably defined by at least one angular section of a surface having rotational symmetry with respect to the axis.
- the bearing surface can be substantially radial with respect to the axis.
- the bearing surface does not always extend over the entire periphery of the nozzle housing. This is especially the case when the outlet channel is an integral part of the finger cot for actuating the valve.
- the bearing surface extends only over an angular section of the periphery of the tubular wall, said tubular wall extending, opposite its open end, in the angular section complementary to the surface d 'support, by an extension in which the part of the retention ring of a nozzle which is not in engagement with the bearing surface can be caught by deformation of the extension.
- Such a partial snap-in is already sufficient to guarantee effective retention even at pressures of at least 20 bar.
- the outlet channel can be provided at its end opening into the nozzle housing with a stud intended to enter a corresponding recess of a nozzle.
- the cross section of the nipple can in particular be dimensioned to be greater than that of the recess of a nozzle for which it is intended, so as to be able to create, when a nozzle is placed in the nozzle housing with the nipple penetrating into the recess, a sealed annular surface at the interface between the stud and the nozzle.
- the contact zone constitutes an exemplary embodiment of the sealing means.
- the stud protrudes into the nozzle housing so that its front face is axially closer to the open end of the tubular wall than the bearing surface.
- the cross section of the tubular surface and / or the cross section of the stud are in the shape of a circle.
- the invention also relates to a diffuser in which a nozzle provided with a retention ring is introduced into the nozzle housing, at least part of the retention ring being engaged behind the bearing surface.
- the part of the retention ring of the nozzle which is not in engagement with the bearing surface can be hooked to the tubular surface by deformation of its extension.

- the invention relates to a diffuser (1) intended to actuate the valve of an aerosol generator in order to diffuse its content.
- a diffuser is provided essentially with a tubular skirt (10), a finger cot (20) located at the top of the skirt and an outlet channel (30, 30 ') placed inside the diffuser, under the finger cot with which it cooperates to actuate the valve.
- the finger cot can be articulated on the skirt by means of a tongue (21) so that it can be pushed towards the inside of the diffuser by pivoting about an axis passing through the tongue. It can also be separated from the skirt by being able to be pushed in towards the interior of the diffuser either by translation or by pivoting about a fulcrum.
- the outlet channel (30, 30 ’) consists of a duct (31) and a nozzle housing (32) intended to receive a nozzle.
- the first end (311) of the conduit (31) is designed to actuate the valve of a pressure vessel such as an aerosol generator and the second end (312) opens into the nozzle housing (32).
- the first end of the conduit (311) is sized to cooperate with the stem (also known as the stem or nozzle) of a male type valve. It would also be possible for this first end to be designed to actuate a female type valve.
- the nozzle housing extends around an axis (A).
- the outlet duct (31) shown in the figures is divided into two sections:
- the second section extends along the axis (A), at least at the level of the second end (312) of the duct.
- the inclination of the second section is dictated only by the intended use of the diffuser or the desired aesthetics. Depending on requirements, it can be horizontal, inclined downwards, inclined upwards as in the present example, or even vertical and in the extension of the first section.
- the outlet channel (30) can be an integral part of the finger cot under which it is formed during the molding of the finger cot, as in the present example. In another embodiment not shown, it can be connected to the skirt, for example by a flexible tongue. Finally, it may consist of an added part (30 ') fixed to the skirt or to the finger cot during assembly, such as the conduit described in French patent application FR 19 00 676.
- the outlet duct (30 ') and the base body of the diffuser, consisting of the skirt (10) and the finger cot (20) are two separate parts connected together by mechanical hooking means, in particular by snap-fastening for example a tenon placed at the top of the outlet duct (30 ') in a corresponding opening made in the finger cot (20).
- the stud (33) protrudes slightly into the nozzle housing (32), which is delimited by a tubular wall (34) coaxial with the stud, but of larger diameter.
- This nozzle housing opens, opposite the nipple (33), on the outside either in the skirt or in the finger cot (case of the example shown here) as required.
- the nozzle (40) consists essentially of a tubular wall (41) closed at one end by a front wall (42) provided with an outlet (421) and open at the other end.
- the tubular wall (41) is provided on its outer face, near the open end, with a retaining ring (43) whose downstream face (431) directed towards the front wall is substantially radial, while the face the opposite upstream (432) is preferably inclined so as to form a ramp.
- the retention ring therefore constitutes a hook.
- the inner face of the front wall (42) can be provided with reliefs to improve the quality of the jet.
- the nozzle can also be provided with an interior part (44) also intended to improve the quality of the jet.
- the nozzle is therefore provided with a recess (45) into which the stud (33) can enter.
- the nozzle housing forms a blind hole closed at the bottom by a radial wall into which the second end (312) of the duct opens.
- the end of the duct can be flush with this bottom wall, or as in the present example, continue with a stud (33) projecting from the bottom wall in the nozzle housing.
- the nozzle is introduced into the nozzle housing until its open end, opposite the front wall (42), touches the bottom wall of the nozzle housing, or when there is a nipple, the nozzle is threaded. on the stud (33) until the inner face of the front wall of the nozzle, or the inner face of the inner part (44), touches the front face of the stud (33).
- the nozzle is forced into the housing.
- the diameter of the nozzle retention ring (43) is greater than the diameter of the cylindrical wall (34) of the nozzle housing.
- the retaining ring acts as a "hard tooth” which grips the softer material in the nozzle housing. The nozzle is therefore retained in the housing by deformation thereof.
- This retention system also seals at the interface between the retention ring and the deformed cylindrical wall of the nozzle housing.
- the upstream end of the nozzle housing (32), located on the outlet channel side, is at least partially open.
- the tubular wall (34) is provided, at a distance from its outwardly open end, with a bearing surface (341) which extends over at least a part of its periphery and behind which can engage a at least part of the retention ring (43) of a nozzle inserted into the nozzle housing.
- the bearing surface (341) is defined by at least an angular section of a surface having rotational symmetry with respect to the axis (A). In the simplest embodiment, the bearing surface (341) is substantially radial.
- the channel (30) is, as here, an integral part of the finger cot (20), it is not possible to simply mold a bearing surface (341) around the entire circumference of the tubular wall (34).
- at least part of the upstream part of the tubular wall (34) continues with an extension (342) beyond the bearing surface (341) in the direction opposite to the open end, thus extending a corresponding part of the nozzle housing.
- the tubular wall (34) is therefore divided into two angular sections: the first ends with the bearing surface (341) and the second, complementary to the first, continues with the extension (342).
- the two angular sections are substantially equal and are equal to approximately 180 °. This is clearly visible in Figures 4, 6, 7 and 8. This means that approximately 50% of the retention ring is snapped behind the bearing surface and the remaining 50% is retained by deformation of the extension (342) . It goes without saying that other values could be provided depending in particular on the molding constraints.
- the nozzle (40) is therefore retained in part by latching the retention ring (43) behind the bearing surface (341) and in part by deformation of the extension (342) of the tubular wall.
- the locking of the retaining ring behind the bearing surface of a on the one hand and the retention of the retaining ring by deformation of the extension (342) on the other hand constitute means for retaining the nozzle in the nozzle housing.
- the front face (331) of the stud is preferably in contact with the inner face of the front wall (42) of the nozzle, or with the rear face of the inner part. (44), with an assembly clearance taking into account the dimensional tolerances of the different parts.
- the seal is provided at the level of the deformation of the extension (342) of the tubular wall by the retaining ring (43), this is not always the case at the level of the snap-fit of the ring retention on the bearing surface. It is therefore preferable to provide additional sealing means.
- the inside diameter of the tubular wall (41) of the nozzle is less than the outside diameter of the stud (33).
- the nozzle is forcefully entered on the stud (33) so that the annular interface (35) between the outer face of the stud (33) and the inner face of the tubular wall (41) of the nozzle forms a connection waterproof clearly visible in Figures 3a, 5a, 6a and 7a.
- the stud (33) protrudes into the nozzle housing (32) beyond the bearing surface (341) so that the front end of the stud (33) is placed further downstream than the bearing surface.
- the front face (331) of the stud is axially closer to the open end of the tubular wall (34) than the bearing surface (341).
- the sealing function and the retaining function are therefore separate. Sealing could be achieved by means other than adjustment of the annular interface.
- polymer materials such as polymer materials (PE, PP, PLA, PHA, PBS) whether new or recycled, from petroleum or natural resources, biodegradable or not, or even compostable or not. They can 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.
- POM, PBT, PA or more generally any polymer sufficiently rigid to ensure a hard tooth effect while being able to be injected with great precision.
- the invention it is possible to manufacture diffusers which can receive and retain nozzles up to pressures of at least 20 bars.
- the nozzles used on diffusers provided with a nozzle housing forming a blind hole of the prior art can be used in this new diffuser. It is therefore not necessary to have a stock of specific nozzles.
- the invention is suitable both for one-piece nozzles and for two-piece nozzles such as those described in patent application PCT / EP2018 / 078705.
