Definitions

  • the present invention relates to a dispensing cover intended to be associated with a conventional pressurized container of the "aerosol" type.
  • the distribution covers known and used so far are generally made in two parts, one fixed, the other mobile.
  • the fixed part is formed by a cover body which is fixed, in particular by snap-fastening, on the associated pressurized container.
  • the movable part of the distribution caps is in the form of a push button arranged at least partially inside the cover body and cooperating with the outlet member of the ejection valve of the pressurized container.
  • the valve is most often arranged on a cup itself fixed by an annular bead of crimping on the upper part of the container body.
  • the push button has, at its upper part, a tongue on which the user acts to cause the opening of the valve; at its lower part, it comprises a bent angled pipe, the axial branch of which comes to cooperate with the outlet member of the valve and the radial branch of which ends in an ejection nozzle placed in line with a window made in the side wall of the hood body.
  • Distribution covers of this kind can be produced either in one piece, or in two separate pieces, by plastic molding.
  • the push-button is, as a first possibility, articulated by means of a hinge coming from molding, relative to the fixed body of the cover.
  • This type of cover generally has an internal skirt coaxial with the external side wall of the cover body; the aforementioned skirt is provided with members, such as pins or a peripheral ring, allowing the snap-fastening of the cover body to the crimping bead of the valve-holder cup of the pressurized container.
  • the push button is no longer articulated relative to the cover body but is mounted to slide along the axis of the valve of the pressurized container, inside a central chimney formed in the body of the hood; on demolding, the push button in question is connected by breakable fasteners, coming from molding, to the wall of the hood body.
  • the above distribution covers raise two kinds of difficulties, one in molding, the other in the positioning of the cover on the associated pressurized container.
  • the presentation covers especially if they are molded in one piece, have a complex configuration requiring molds which are expensive to manufacture and which complicate the demolding operations.
  • most of the current distribution covers do not lend themselves, due to their design, to automatic installation, almost without manual intervention on pressurized containers.
  • a distribution cover produced in two parts, one fixed, the other mobile, the fixed part comprising a cover body provided with means ensuring its holding relative to the pressurized container, the movable part consisting of a push button cooperating with the valve outlet member, a window being formed in the side wall of the cover body in line with the button ejection nozzle- pusher.
  • the fixed part of the cover comprises a sleeve fitted inside the cover body, said sleeve coming to bear on an element of the pressurized container, means being provided for ensuring the angular positioning of the cover body relative to the sleeve.
  • the push button is made in one piece with the sleeve, but when the cover body is placed on the sleeve, the push button is detached from the sleeve by two trocars which come cut the tabs that attach the push button to the sleeve.
  • the push-button is then placed on the valve tube and its pivot axis is maintained upwards thanks to notches provided in the internal wings of the cover body.
  • the sleeve which ensures the centering of the cover body, is hung on the crimping bead of the valve cup and centered on the latter.
  • this cover has several disadvantages: first, the axis of the push button is necessarily in an area fairly close to the axis of the cover and the valve outlet tube, so that during operation, the rod valve outlet is subjected to bending, which is detrimental to the proper functioning of the valve; secondly, the cost price of the cover is quite high for two reasons: on the one hand, the cover body necessarily has two internal fins which extend from the upper wall to the level of the axis of articulation , which requires a large amount of material and, on the other hand, it is necessary to respect the tight tolerances so that when the cover body is mounted on the sleeve, the tongues are cut by means of the trocars without damaging the 'articulation provided for the push button; thirdly, the operation of the push button is necessarily carried out through an orifice in the side wall of the cover, which is unsightly and does not allow the establishment of a tamper-evident plate.
  • the present invention aims to provide a cover dispenser which not only allows a simple, rapid and mechanizable installation on a pressurized container but which, moreover, avoids all the drawbacks presented by the cover described in the patent of the United States of America 3,661,300.
  • the present invention therefore relates to a dispensing cover intended to be associated with a pressurized container of the "aerosol can" type, this container being produced in two parts, one fixed and the other mobile, the fixed part of the cover comprising , firstly, a cover body provided with means ensuring its maintenance with respect to the pressurized container and, secondly, a sleeve, which is fitted inside said cover body, comes to bear substantially on an element of the container pressurized and comprises members ensuring its centering relative to the valve cup of the container, means being provided for ensuring the angular positioning of said cover body relative to said sleeve, the movable part of the dispensing cover consisting of a push button, which cooperates with the outlet member of the ejection valve of the associated container, said push button comprising an ejection nozzle to a pipe, which places the outlet member of the valve with said nozzle, said push button being molded in one piece with the sleeve and being operable through an opening in the wall of the cover body,
  • the cover body comprises members making it possible to limit the movement of the push button around its articulation hinge in the opposite direction to that which corresponds to the opening of the valve, these members consisting of at least one lateral stop integral with the push button and intended to cooperate with the lower edge of a guide wing of the hood body; on demolding, the push button is kept fixed inside the sleeve by means of a breakable fastener coming from molding; the cover body internally comprises members ensuring the guidance of the push-button in a plane passing through the sliding axis of the valve outlet member and perpendicular to the axis of the articulation hinge; the guide members of the push-button consist of two wings between which the push-button engages, said wings being arranged on either side of the window of the cover body, to the right of which is disposed the nozzle d 'ejection of the push button; the opening provided in the wall of the hood body, to allow operation of the push button, is made in the upper wall of said hood body and is
  • the cover body comprises, at its base, a latching element, which cooperates with a corresponding latching element carried by the wall of the pressurized container; the means allowing the angular positioning of the cover body relative to the sleeve simultaneously ensures that the sleeve rests on the crimping bead of the valve-holder cup of the container; the means allowing the angular positioning of the cover body relative to the sleeve comprise at least one lug provided in relief inside the side wall of the cover body and at least one notch formed on the sleeve and intended to receive the lug cited above; the centering members of the cover consist of two studs substantially parallel to the axis of the sleeve and projecting from the two concave parts of said sleeve, the two aforementioned studs fitting inside the valve holder cup of the container; the side wall of the cover body is provided with a discontinuous annular ring which snaps inside a peripheral groove made on the body of the container

  • the side wall of the cover body comprises at least one internal
  • the present invention also relates to an assembly formed by a pressurized container of the "aerosol can" type and a dispensing cover as defined above.
  • the side wall of the hood body comprises a ring which snaps inside a peripheral groove provided on the body of the pressurized container and the associated pressurized container is obtained by stamping and forming a metal pellet, said container being formed in a warhead in its zone, which is opposite to its bottom, a valve holder cup being fixed by crimping at the end of the warhead; the peripheral groove is formed on the pressurized container in the area of connection of the warhead with the cylindrical side wall of the container body.
