Definitions

  • the present invention relates to a protective cover intended to be mounted on a circular cylindrical casing of a distribution member, such as a pump.
  • the cover comprises a body, as well as a cylindrical sleeve intended to engage around or outside the circular cylindrical cover, in order to hold the cover on the circular cylindrical cover in a removable manner.
  • a cylindrical sleeve intended to engage around or outside the circular cylindrical cover, in order to hold the cover on the circular cylindrical cover in a removable manner.
  • protective covers which comprise a body and a circular cylindrical bush made of plastic.
  • the circular cylindrical casing is generally made of aluminum, possibly with an annular groove.
  • the circular cylindrical bush comes into frictional contact with the casing or, as a variant, the bush comprises projecting internal profiles which snap into the annular groove of the casing. In either case, the cover can be removed from the casing with a reasonable tensile force.
  • the casing is already made of aluminum and we know that it is not easy to mount an aluminum part on another aluminum part, because of the low elasticity of this metal.
  • Aluminum is easily deformed, but has no shape memory. On the contrary, some plastics can easily deform, both elastically and by creep.
  • a plastic sleeve with internal profiles expands and then returns to its original shape, when the profiles come to be housed in the annular groove. This is not possible with an aluminum sleeve or even a rigid plastic sleeve. The snap-fit would be final or the internal profiles would be laminated.
  • the object of the present invention is to meet the challenge of mounting a rigid cylindrical bush, made of plastic or preferably of metal, such as aluminum, on a pump or valve casing.
  • the elasticity of the sleeve must be sought not in the specific characteristics of the material used, but in its particular configuration.
  • the present invention proposes that the cylindrical sleeve has a non-circular cross section defining areas of larger diameter and areas of smaller diameter, and thus exhibiting elastic deformability, the areas of smaller diameter delimiting a cylinder.
  • circular internal inscribed circular diameter equal to or slightly smaller than the external diameter of the circular cylindrical casing.
  • the sleeve may have any cylindrical, geometric or any shape, such as a star, or with meanders or zigzags, thus defining areas of smaller diameter delimiting an inscribed circular cylinder. It is preferable to have at least three zones of smaller diameter to ensure proper fit on the cabinet.
  • the cover may further comprise a circular cylindrical sleeve in engagement with the body, the cylindrical sleeve defining areas of larger diameter delimiting an external inscribed circular cylinder having a diameter equal to or slightly greater than the internal diameter of the circular cylindrical sleeve, the cylindrical sleeve being engaged in the circular cylindrical sleeve, its larger diameter areas coming into contact with the circular cylindrical sleeve, while its smaller diameter areas remain away from the circular cylindrical sleeve.
  • the circular cylindrical sleeve may include a re-entrant shoulder which engages the ends of the areas of larger diameter, so as to firmly hold the cylindrical sleeve between the body and the re-entrant shoulder.
  • the socket does not have no need to come into radial engagement supported inside the sleeve, since it is blocked by the re-entrant shoulder.
  • the cylindrical sleeve can have a polygonal cross section, thus defining several flat faces connected by ridges, the flat faces forming the areas of smaller diameter and the ridges forming the areas of larger diameter.
  • a cylinder with slightly curved, domed or profiled faces or with sharp or rounded edges may be termed a cylinder with a polygonal section.
  • the planar faces define an internal inscribed circular cylinder having a diameter equal to or slightly less than the external diameter of the circular cylindrical cover, such that the planar faces contact the circular cylindrical cover.
  • the plane faces will come into contact with the covering at the level of their median line, which ensures a symmetrical and balanced elastic deformation.
  • the edges are then located equidistant from two adjacent contacts.
  • the cylindrical sleeve has elastic deformability at its plane faces and / or at its edges.
  • edges are rounded, for aesthetic reasons or in order not to damage the sleeve.
  • the cylindrical sleeve may include a bottom, which gives it greater integrity.
  • the cylindrical sleeve is made of metal, advantageously of aluminum.
  • the cover is made entirely of metal, advantageously of aluminum.
  • the present invention also defines a fluid product dispenser comprising a dispensing member, such as a pump, a fluid reservoir, a fixing member for fixing the dispensing member on the fluid reservoir, a casing mounted on the fixing member and a cover as defined above mounted on the casing.
  • a dispensing member such as a pump
  • a fluid reservoir such as a fluid reservoir
  • a fixing member for fixing the dispensing member on the fluid reservoir
  • a cover as defined above mounted on the casing.
  • the cover may or may not include a circular cylindrical sleeve.
  • the socket is preferably made of aluminum, as are the body and the sleeve, if there is one.
  • the spirit of the invention lies in the fact of giving an elastic characteristic to the sleeve, which does not come from its constituent material, but from its configuration, its particular implementation, its architecture or its geometry.
  • the non-circular shape (in cross section) of the sleeve gives it an excess of length which gives it an elasticity that it would not have if it were circular.
  • the convolutions, meanders, zigzags or successions of flat faces and edges or angles provide structural elasticity, like that of a coil spring or an accordion, and not intrinsic, like that of certain plastics.
  • cylinder or “cylindrical” must be understood in their mathematical sense, that is to say resulting from the displacement of a line of constant direction along a closed curve, which can be geometric or not.
  • a dispenser comprising a reservoir R forming a shoulder S from which extends a neck (not visible).
  • a distribution member P such as a pump or a valve, is capped by a pusher B which allows to actuate and dispense fluid.
  • the dispensing member comprises a fixing member enabling it to be mounted fixedly on the neck.
  • This fixing member is surrounded by a covering H.
  • this covering H is generally circular cylindrical, even if it may include an upper flap.
  • the covering H is forcefully engaged around the fixing member and can come with its lower edge in contact with the shoulder S of the reservoir R.
  • the covering H is made of metal, often of aluminum, with thin wall thickness, of the order of a few tenths of a millimeter.
  • the pusher B protrudes through the casing H: in its axial travel, the pusher B can enter the casing H.
  • the dispenser is completed by a protective cover C which covers the push-button B and surrounds the casing H.
  • the cover C is held in a removable manner by friction around the casing H.
  • the cover C comprises a body 1 which defines a reception housing 11 open downwards.
  • the housing 11 has an overall cylindrical configuration, which may or may not be circular.
  • the body 1 can have any external contour, mainly dictated by aesthetics. It can be made in one piece or in several assembled parts. Its constituent material can be chosen from metals, plastics, ceramics, wood, glass, etc.
  • the body 1 is solid and made in one piece from aluminum. It can be molded, pressed or machined.
  • the protective cover C also comprises a socket 2 which has a cylindrical configuration, but not a circular one.
  • the horizontal cross section of the sleeve 2 may have a conventional geometric shape, in particular polygonal. It can also have a more complex shape, with or without symmetry.
  • the sleeve 2 is attached to the receiving housing 11 of the body 1. It can be maintained by friction alone.
  • the cover C can only comprise two constituent elements, namely the body 1 and the sleeve 2.
  • the sleeve 2 is engaged in the housing 11 of the body 1, but it is held in place by a sleeve 3, which is also engaged in the housing 11 and held in place. place, for example by friction.
  • the sleeve 11 comprises a circular cylindrical main section 31 and a re-entrant shoulder 32 at its lower end.
  • the circular cylindrical main section 31 defines an inner side 31i and an outer side 31e.
  • the sleeve 2 has a regular hexagonal horizontal cross section. It thus defines six flat faces 21 and six edges 23, connected to each other in an alternating manner.
  • the flat faces 21 each comprise an interior side 21i and an exterior side 21e, as well as two opposite free edges 22.
  • the ridges 23 each comprise an interior side 23i and an exterior side 23e, as well as two opposite free edges 24.
  • the edges free 22 and 24 together form the two opposite hexagonal edges of the sleeve 2. It can be noted that the edges 23 are not sharp, but on the contrary rounded or blunt.
  • the sleeve 2 is inserted into the sleeve 3. Due to its hexagonal shape, the outer sides of the ridges 23 come into more or less full contact with the inner side 31i of the sleeve 3. The outer sides 21e of the flat faces 21 remain in contact. distance from the inner side 31i of the sleeve 3.
  • the sleeve 2 may be fully inscribed inside the sleeve 3 or, alternatively, it may protrude out of the sleeve 3 on one side. It is preferable that the sleeve 3 comes into abutment with one of its free hexagonal edges against the re-entrant shoulder 32.
  • the rounded edges 23 allow more extensive contact with the sleeve 3, which reduces the risk of damaging it by folding or crazing. It is also possible to provide for rounding or bevelling the hexagonal free edges to facilitate the insertion of the sleeve 2 into the sleeve 3.
  • the assembly formed by the sleeve engaged in the sleeve ( figure 4 ) is inserted into the receiving housing 11 of the body 1 to form the cover C of the figure 1 . It is essential that the sleeve 3 is fixedly received in the housing 11, because it is this which holds the sleeve 2 in place, thanks to its re-entrant shoulder 32.
  • the sleeve 2 is either in contact with the covering H, or in contact with the sleeve, or out of contact with the two. This gives it sufficient clearance to deform either outward or inward. Even if the deformation results in a less strong radial bearing against the sleeve 3, the sleeve 2 nevertheless remains blocked by the re-entrant shoulder 32 of the sleeve. Thanks to this elastic deformation, an aluminum sleeve can be mounted on an aluminum casing. However, it is not excluded that the sleeve 3 can be made of another metallic or plastic material.
  • the sleeve 3 can be omitted, so that the sleeve 2 can only be engaged in the housing 11 of the body 1.
  • the casing H is always circular cylindrical, but the 2 "socket has a cross section which is admittedly symmetrical, but not geometric. It is formed by a succession of more or less lobes.
  • large forming areas of larger diameter 23 and areas of smaller diameter 21".
  • the smaller diameter areas 21 delimit an internal inscribed circular cylinder having a diameter equal to or slightly less than the outer diameter of the circular cylindrical casing H.
  • the larger diameter areas 23" delimit an inner inscribed cylinder of oblong, oval shape or elliptical, corresponding to a housing of the body 1 of corresponding shape.
  • the socket 23 "' has a cross section forming rounded hollows 21"' and tips 23 "'.
  • the inscribed cylinders are both circular.
  • the sleeve of the invention includes areas of smaller diameter, formed by the midpoints of the plane faces in the case of a polygonal shape ( figures 1 to 6 ) or the funds of the lobes ( figure 7 ) or hollows ( figures 8 ). These smaller diameter zones delimit an internal inscribed circular cylinder having a diameter equal to or slightly smaller than the external diameter of the circular cylindrical casing H.
  • the sleeve Whatever the shape of the sleeve, it comprises zones of larger diameter, formed by the edges in the case of a polygonal shape ( figures 1 to 6 ) or the tops of the lobes ( figure 7 ) or spikes ( figures 8 ). These larger diameter zones delimit an external inscribed cylinder which corresponds to the shape of the receiving housing 11 of the body or to that of the sleeve 3.
  • the sleeve of the invention can be cylindrical over all or part of its height. It can pass through or, on the contrary, be closed off by a bottom, so as to form a bucket.
  • the sleeve is preferably produced by stamping an aluminum foil having a thickness of the order of a few tens of millimeters. Once the sheet is stamped, it has the shape of a cup: you can choose to cut the bottom or not.
  • a cover which provides better elasticity and therefore a different feeling or feel when removing and replacing the cover on the covering.
  • a cover can be made with an aluminum socket and even entirely in aluminum, while the casing is also in aluminum.
