Definitions

  • valves according to the preamble are commonly used for pressure containers, in particular for aerosol generators.
  • a valve body is attached to a cup forming an internal chamber in which there is a spring, a seal and between the two at least part of the valve.
  • the spring pushes the valve against the seal so that the valve is closed.
  • To insert the seal, spring and valve it is essential to have an access opening before final assembly.
  • the cup is crimped onto the top of the valve body which is provided with an annular extra thickness at its top. This method works very well when the cup is metallic.
  • the current trend tends to eliminate metal parts and replace them wherever possible with plastic in order to facilitate the recycling of aerosol generators. We therefore know of valves in which the cup is also made of plastic.
  • valve body is fixed to the cup by snap-fastening.
  • snap-fastening we will cite the document FR 2 508 136 A1 . This requires more complex molds to produce, on the one hand, the snap tabs on the cup or the body of the valve and on the other hand the corresponding recesses on the other part.
  • the parts must be oversized to take into account the height of the fastener.
  • the objective of the invention is to remedy these drawbacks.
  • valve of claim 1 This objective is achieved with the valve of claim 1. This solution makes it possible to have simpler parts to manufacture. In addition, no part can be expelled towards the user in the event of defective fixing of the valve body to the cup.
  • the interior face of the cup and the valve body are made of plastic, preferably polypropylene (PP) or another polyolefin.
  • PP polypropylene
  • the materials chosen for one of the parts are compatible with that of the other part.
  • the cup can consist of at least one metallic outer layer, preferably aluminum or tinplate, and an inner layer of plastic, preferably polypropylene (PP) or another polyolefin.
  • metallic outer layer preferably aluminum or tinplate
  • inner layer of plastic preferably polypropylene (PP) or another polyolefin.
  • the valve body may be welded to a flat portion of the cup that extends beyond the valve body. It can also be curved so that its interior face or its exterior face has a generally convex shape. In both cases, the edge of the central opening can be straightened, in particular straightened on the side of the exterior face.
  • a flat cup at least at the level of the valve body, or slightly curved will be chosen for example when the cup contains at least one metallic layer. The straightened edge helps strengthen the cup.
  • the central opening of the cup is made in a bottom wall of a cylindrical well, the valve seal being placed against the bottom wall of the cylindrical well.
  • the advantage of a well can be to raise the central opening in relation to the peripheral edge used to fix the valve on the housing. It can also make it possible to place reinforcing ribs on the exterior face of the cup, in contact with the face exterior of the cylindrical well. Reinforcement ribs can be provided on at least one face of the cup even when the central opening of the cup is not made in a back wall.
  • the end of the valve body provided with the tapered edge enters the cylindrical well.
  • the welding can be carried out either between the fixing ring inserted into the well and the bottom wall of the well, or between the fixing ring wider than the well and a peripheral section of the cup which surrounds the well. We can also consider welding the side walls of the valve body and the well to each other.
  • the valve body may comprise a tubular body provided with a fixing crown by which the valve body is welded to the cup, with the body valve placed completely outside the well, the weld being made between the fixing crown wider than the well and a peripheral section of the cup which surrounds the well.
  • the valve (1) of the invention can be used in all positions. In the figures illustrating this request, the valve is shown with the stem pointing upwards.
  • the references “top” / “bottom” or “upper” / “lower” only have a relative value in relation to the representations in the attached figures. It goes without saying that the valve can be used in all positions and what is up in the position shown here will not necessarily be up in use.
  • the valve extends longitudinally relative to a main axis (A), vertical in the representations of the attached figures.
  • the terms “radial”, “axial” and “transverse” relate to this main axis (A).
  • the cup (50) constitutes a separation between the side of the valve intended to be placed inside the housing and the other side intended to be outside the housing.
  • the terms “interior” and “exterior” refer to the elements located on the interior or exterior side of the cup.
  • the terms “internal” and “external” refer to a particular component (specifically the valve body) and define what is inside or outside that component, regardless of whether it is a component located on the valve body. interior or exterior face of the cup.
  • the example presented here is a male type valve having as valve a stem (30) of which part of the stem projects out of the valve.
  • the invention can also be applied to a female type valve having as valve a seat located in the valve body and having to be actuated by an external rod (generally that of a diffuser) penetrating into the valve.
  • the valve body (10) mainly consists of a tubular body (11) partially closed at a first end, called the lower end, by a bottom wall (12) having an inlet opening (121).
  • the tubular body (11) and the bottom wall (12) together define an internal chamber (13).
  • Vertical ribs (131) may be provided in the bottom of the internal chamber, close to the bottom wall. These ribs project radially from the tubular body towards the center of the internal chamber forming a receiving space in which a first end of the spring (20) can be received and retained radially.
  • a fixing pin (14) can be provided on the external face of the bottom wall (12) to fix, for example, a dip tube or anti-sagging means. This tenon (14) is tubular in shape and surrounds the inlet opening (121).
  • At least one opening (112) can be provided in the tubular body (11), which opening forms a passage bringing the external face and the internal face of the tubular body into contact.
  • This opening which is not obligatory, serves as an additional gas intake to improve the quality of the spraying.
  • the second end of the tubular body (11) ends in a tapered edge (111). It is surrounded by a fixing ring (15) which consists of a tubular wall connected to the second end of the tubular body by a transverse wall (151). This transverse wall is for example parallel to a plane perpendicular to the main axis (A). It can be solid as in the present example, or crenellated if it is not necessary to ensure a seal between the two faces of this transverse wall.
  • the annular edge (upper face) (152) of the fixing crown (15) is preferably provided with at least one extra thickness of material going completely around the crown and serving as an energy director during ultrasonic welding of the valve body on the cup. In the example presented here, there are two rings of extra thickness of material (152a, 152b).
  • the stem can be carried by a valve to be inserted at least partially into the valve body (therefore by a stem) if it is a male type valve, or by a diffuser intended to actuate the valve if it is This is a female type valve.
  • the cup can be made entirely of plastic. It is also possible that it is made up, as in the present example, of an outer layer (53) metallic and an inner layer (54) of plastic material.
  • the edge (521) of the central opening (52) can be straightened, particularly on the side of the exterior face.
  • the stem (30) is of standard shape. It consists of a cylindrical wall (31) open at its upper end (311) and closed at its lower end forming a product outlet channel. One or more orifices (312) placed at the bottom of the outlet channel pass radially through the cylindrical wall to bring the internal face and the external face of said cylindrical wall (31) into contact.
  • the cylindrical wall (31) constitutes the product outlet rod.
  • This cylindrical wall continues with a crown (32) of larger diameter having on its external face vertical channels or vertical ribs allowing the product to bypass the crown.
  • the outer casing of this crown has a diameter slightly smaller than the internal diameter of the tubular body (11) of the valve body so that it can enter the latter while being guided.
  • the crown (32) is provided with a sealing rib (321) to ensure sealing with the valve seal (40).
  • the crown (32) continues downwards by a guide pin (33) intended to cooperate with the second end of the spring (20).
  • the valve seal (40) is also a classic part. It is an annular seal whose internal diameter is chosen to tightly enclose the cylindrical wall (31) of the stem. The external diameter is chosen so that the entire tapered edge (111) of the tubular body of the valve body can be in tight support against the valve seal (40).
  • the valve seal takes place in the space delimited on the one hand by the internal face of the fixing crown and on the other hand by the transverse wall (151).
  • the spring is trapped between the bottom wall (12) of the valve body and the guide pin (33) of the stem.
  • the valve of the invention is assembled as follows.
  • the spring (20) is placed in the bottom of the internal chamber (13) with its first end located between the vertical ribs (131).
  • the valve seal (40) is mounted on the stem (30) so that on the one hand it blocks the orifices (312) of the stem and on the other hand it is in tight support against the sealing rib (321).
  • the stem/joint assembly is inserted into the valve body by the guide pin (33) so that the latter (33) penetrates the second end of the spring (20).
  • the cup is then put in place by passing the free end of the stem through the central opening (52).
  • the cup is brought closer to the valve body until the annular edge (152) is in contact with the interior face (54) of the cup.
  • the seal valve (40) is in tight support against the tapered edge (111). All that remains is to weld the cup and the valve body at the level of the annular edge (152). This welding can be carried out by any appropriate means, and in particular by ultrasonic welding or by rotation welding.
  • the cup is substantially flat at the level of the valve body and around this valve body.
  • the height of the internal face of the fixing crown is substantially identical to the thickness of the valve seal (40).
  • the tapered edge (111) helps to press the seal tightly against the interior face of the cup.
  • the seal between the cup (50) and the valve body (10) is therefore ensured by the valve seal crushed against the interior face (54) of the cup by the tapered edge (111) forming an entirely annular seal. around the central opening (52).
  • the welding at the interface between the fixing ring and the cup therefore does not need to be waterproof. It must only hold the valve body against the cup against the effect of the spring (20) and ensure good pressing of the valve seal (40) against the interior face (54) of the cup. It is therefore possible that the weld is not continuous.
  • the cup not to be flat and in particular for the central opening (52) to be located on a bottom wall of a well into which at least part of the crown (32) of the stem penetrates.
  • the upper part of the valve body with the tapered edge (111) and the fixing crown (15) also penetrates into the well.
  • the weld between the valve body (10) and the cup is made at the bottom wall of the well.
  • the fixing ring (15) remains at the top of the tubular body as in the present example and is dimensioned to penetrate the well. We could also consider welding the cylindrical side walls of the valve body and the well.
  • the welding is carried out at a peripheral section of the cup which surrounds the well.
  • the tubular body (11) with the tapered edge (111) enters the well, while the fixing ring, which is wider than the well, is placed lower than the edge tapered.
  • valve seal (40) is fixed to the bottom wall of the well, for example by overmolding.
  • a tapered edge of the valve body it is no longer necessary for a tapered edge of the valve body to keep it pressed against the interior face of the cup.
  • the body valve does not enter the well. This fulfills the role of the upper part of the valve body and the valve body itself can be shorter.
  • the fixing crown, wider than the well, remains at the top of the valve body.
  • the welding is carried out at a peripheral section of the cup which surrounds the well. The valve body can then be welded in a watertight manner. If the weld is not waterproof, it is also possible to keep a tapered edge as in the example presented here and to insert a second joint between the peripheral section and the tapered edge.
  • valve body and cup must be compatible to allow the valve body to be welded to the cup.
  • polypropylene, or other polyolefins will be chosen for the valve body and the cup or the plastic layer of the cup.
  • the valve body and cup are not necessarily made from the same plastic.
  • valve according to the invention lies in the fact that no part can be ejected out of the valve. In fact, all the parts are located on the side of the interior face of the cup and none is sized to pass through the central opening. The weld between the valve body and the cup is not subject to any tensile stress. It therefore does not need to be particularly resistant.
