Definitions

  • the aerosol container valves at present in use comprise a main body securable to the top of an aerosol container, a hollow stem through which the aerosol material can be caused to exit from the container, and a spring, one end of which abutting on the main body and the other end of which abutting on the stern, this spring tending to urge the stem away from the main body.
  • the main body and stem are made of plastic material, while the spring is of metal. There fore, the main body, stem and spring are obtained separately and next interconnected and then assembled on the top of the aerosol container.
  • the separate provision for the main body, stem and spring of the valve and the connection thereof involve production costs which are comparatively high; it is also apparent that where the connection for the main body, stem and valve, particularly the spring positioning, is not perfectly accomplished, the valve may faultily operate or be also unusable.
  • An object of the present invention is to provide an aerosol valve comprising a main body, a stem and spring means operating between the stem and main body, directly integrally made by a single stamping operation, so that the cost for the valve is extremely reduced.
  • Another object of the invention is to provide an aerosol valve of a simple structure, reliable and wherein the deformable spring means operating between the main body and stem are enclosed and protected within the main body, so as not to be damaged during the operations for assembling the valve onto the container bottom.
  • an aerosol valve wherein the main body, stem and resiliently yieldable means reacting between the stem and main body are integrally made of resiliently deformable material, the main body being substantially shaped as a socket with a continuous peripheral wall and a bottom having a hole, from one side of which a tubular extension projects from the bottom and extends outwardly of the socket-shaped body and on the otherside of which there projects from said bottom at least one elongated flexible arm forming said resiliently yieldable means and extending within the body to said stem, at least one portion of which projects beyond the free edge of the socket-shaped body.
  • FIG. 1 is an axial longitudinal section of the valve
  • FIG. 2 is a cross-section of the valve according to line II-II of FIG. 1;
  • F IG. 3 is an axial section of the valve as assembled on the bottom of an aerosol container.
  • the valve is integrally made of resiliently deformable material, preferably plastic material, and comprises a main body substantially configurated as a socket and formed of a continuous peripheral wall I and a bottom 2, having a hole from one side of which a tubular extension 3 projects and extends outwardly of the socket-shaped body, and on the other side of which four elongated flexible arms 4 project from the bottom 2 and extend within the socket-shaped body to a stem 5 projecting beyond the shaped free edge 6 of the main body.
  • a main body substantially configurated as a socket and formed of a continuous peripheral wall I and a bottom 2, having a hole from one side of which a tubular extension 3 projects and extends outwardly of the socket-shaped body, and on the other side of which four elongated flexible arms 4 project from the bottom 2 and extend within the socket-shaped body to a stem 5 projecting beyond the shaped free edge 6 of the main body.
  • Longitudinal ribs 7 project from the inner surface of the peripheral wall 1 for the socket-shaped body and extend from the bottom 2 to adjacent the edge 6 of the main body.
  • the flexible anns 4 project inwardly of the cylindrical bore or recess defined by the inner surface of the tubular extension 3, and this for enabling a ready manufacturing of the valve by stamping. It
  • the stem 5 is internally hollow and has at least one small hole 8 passing throughout the width of the wall for said stem 5.
  • the bore or recess of the stem is closed at the bottom by a wall 9 to which the upper ends of the flexible arms 4 are connected.
  • the elongated arms 4 because of the relatively reduced width thereof, the somewhat reduced cross-section thereof and length thereof, are readily flexible and may resiliently be deformed when a pressure action is exerted on the stem 5, tending to move the latter near the bottom 2 and to tilt it laterally of the main body axis.
  • FIG. 3 wherein the valve is shown as mounted onto a top 10, provided with a seal 11 and of a type intended to be assembled on an aerosol container in a per se known manner.
  • the stem 5 When the valve is mounted on the top 10, the stem 5 is kept pressed to the top 2, so that at inoperative condition the arms 4 will take the bent position as shown in FIG. 3. Under these conditions, when the valve is mounted on an aerosol container, the liquid in the container will move up through the plastic tube 14 within the space defined by the wall 1 and bottom 2 of the socket-shaped main body, so that within said socket body there is normally a liquid, while outside the socket body there is the propelling gas for maintaining the pressure inside the container.
  • valve structure simplicity will be apparent and it will be readily understood that such a valve is reliable and inexpensive to produce.
  • An aerosol valve securable within the sealed closure top of an aerosol container comprising:
  • a body portion of a general cup-shape having cylindrical outer walls, a circumferential upper free edge, and a bottom integral with said outer walls with a centrally located hole extending through said bottom;
  • At least one elongated resiliently yieldable arm integral with said bottom and extending upwardly from adjacent said hole, said arm having an engaging surface adjacent the upper end;
  • a stern integral with said upper end of said yieldable arm and operable in a vertical direction with said yieldable arm, said stem extending upwardly from said yieldable arm beyond said free edge and having passage means therein; whereby said valve when secured within said closure top is sealed against the inside surface of said closure top adjacent said free edge, said stem projects upwardly through said top, and said engaging surface of said yieldable arm is coupled to said inner surface of said closure top to resiliently deform said yieldable arm downwardly causing said yieldable arm to urge said stern upwardly.
  • An aerosol valve securable within the sealed closure top of an aerosol container comprising:
  • a body portion of a general cup-shape having cylindrical outer walls, a circumferential upper free edge, and a bottom integral with said outer walls with a centrally located hole extending through said bottom;
  • At least one elongated resiliently yieldable arm integral with said bottom and extending upwardly from adjacent said hole, said arm having an engaging surface adjacent the upper end;
  • annular seal member positioned adjacent said free edge and mounted concentrically around said stem, said seal member sealing said valve to said closure top and providing an operable seal on the inner annular surface of said member between said passage means and the interior of said container; whereby said valve when secured within said closure top is sealed against the inside surface of said closure top adjacent said free edge, said stem projects upwardly through said top, and said engaging surface of said yieldable arm is coupled to said inner surface of said closure top to resiliently deform said yieldable arm downwardly causing said yieldable am to urge said stem upwardly.
