Definitions

  • the invention relates to a valve for pressurized containers such as aerosol cans, with a movable against a valve seat and in the rest or closed position against this closure member.
  • the object of the present invention is to form a valve of this type, which is opened by pressing, but which does not require any special spring element.
  • the individual parts of a valve of the type in question are generally made of plastic of different elasticity in the injection molding process. If a spring element is omitted, not only is there a component, its manufacture and assembly, but there is also the possibility of working without metal or a plastic selected according to its resilient properties. Avoiding such plastic and in particular metal is an advantage for products that do not tolerate contact with metal and change as a result.
  • a lever AC is pivoted at point A.
  • the points B and C have traveled different distances.
  • the distance BD is smaller than the distance CE.
  • These different lengths of route are illustrated by the thick arrows.
  • the part F is a valve closure member which bears against a valve seat G.
  • the valve seat G is connected to the part H.
  • the valve closure member F is connected to point C and the valve seat G to point B of the imaginary lever AC.
  • a rod which is arranged displaceably centrally within the sleeve and the slide sleeve and which has the closure member at its upper end and is connected at its lower end to the radially inner ends of the arms, the joints and the adjacent regions of the sleeve being so elastic that they absorb a movement of the arms caused by a downward movement of the slide sleeve in a radially outward direction by a radial spreading movement.
  • the slide sleeve according to the invention represents the part H with the valve seat G.
  • the arms form the levers A-C.
  • the rod corresponds to the part that carries the closure member F.
  • the bushing which can be firmly inserted into the container, forms the pivot point A or, if several arms are used, several pivot points A.
  • the bush Due to its elasticity, the bush returns to its original position when the slide sleeve is released. Its radially spread area contracts again and thereby pushes the slide sleeve and the rod back into their original position. So that the closure member rests on the valve seat, and the valve is closed.
  • the valve according to the invention therefore does not require a special spring element.
  • the plastic forming the sleeve only has to be adjusted so that it has the desired elasticity and spring force.
  • the arms enclose an acute angle with the bush in their rest position and the elastic restoring force of the material of the bush is so great that it returns to its rest position after a radial spreading movement.
  • the aforementioned acute angle between the arms and the bushing has the result that it moves the arms in their radial inward movement - when viewed from FIGS. 1 and 2 - upwards or in the closed position of the closure member. As a result, the valve automatically returns to its closed position after opening.
  • the Bush with the joints and the arms is formed as one part (injection molded), the joints with the arms being molded onto the lower end of the bush.
  • the joints with the arms being molded onto the lower end of the bush.
  • four arms will be used.
  • three, five or another number of arms are also conceivable.
  • the rod has an annular saving at its lower end
  • the arms have thickenings at their inner ends or merge into a ring and these or these are pressed into the saving or is.
  • the recesses in the slide sleeve are provided in their lower open ends, webs from this end protrude from one side to about half into the recesses and have locking projections at their ends on their upper sides, so that the arms carried by the cutouts rest on the webs and are clamped between them, a lateral and upper limit of the cutout and a locking projection.
  • the slide sleeve is pressed to open the valve.
  • the slide sleeve protrudes from the sleeve and on the protruding part a handle is attached at a distance above the upper edge of the sleeve or the can lid holding it, which corresponds to the maximum stroke of the rod.
  • the grip board is thus both a handle for pressing down the slide sleeve and a stop for limiting the stroke.
  • noses are provided on the arms and the tops of the recesses are shaped that they form a swivel bearing for the noses resting against them. This reduces the opening force and prevents jamming.
  • the sleeve surrounds the slide sleeve with such a small distance that it represents a guide for the latter, a groove is provided in the inner wall of the sleeve and a sealing ring which bears against the slide sleeve is held in this.
  • a sealing lip abutting on the sleeve is formed on the outer wall of the slide sleeve in the area enclosed by the sleeve.
  • the rod is integrally connected to the arms via joints formed as material dilutions.
  • the Yentilverschlußglied is a special component that is pushed onto the rod and locked and connected to it by a tongue and groove connection or the like.
  • the invention further provides that the surfaces of the valve seat and the valve closure member which abut one another in the closed or rest position are conical, the conicity being selected differently so that a linear contact occurs axially on the outside.
  • an elastic clamping ring rests on the latter in the region of the elastic radial expansion.
  • the invention also provides a possibility of simply placing the valve as a self-contained unit on a container, an aerosol can, a bottle or the like and connecting it to this container or the like.
  • the sleeve is concentric and old radial distance lies within a sleeve connected to it in one piece and this can be placed pressure-tight on a container or the like.
  • the sleeve can have a thread for screwing on, a snap lock for fitting or any locking or latching for connection to the container, the can, the bottle or the like.
  • FIG. 2 shows a representation similar to FIG. 1, which has also already been explained
  • FIG. 3 is a side view, partly in section, of an embodiment of the valve according to the invention.
  • FIG. 4 is a side view, partly in section, of a second embodiment of the valve according to the invention.
  • Fig. 5 is a perspective view of the slide sleeve of the second embodiment
  • Fig. 6 is a perspective view of the sleeve of the second embodiment.
  • Fig. 3 shows the slide sleeve 12 with the handle 14 and the valve seat 16.
  • Four recesses 18 are provided in the lower end of the slide sleeve 12.
  • 5 shows the slide sleeve 12 of the alternative embodiment according to FIG. 4, the cutouts 18 are identical in both embodiments. With regard to the recesses 18, reference can therefore generally be made to FIG. 5.
  • the cutouts 18 are partially delimited downwards by the webs 20.
  • the upper sides of the recesses 18 form the pressure edges 22.
  • the sleeve 24 surrounds the slide sleeve 12. In a manner not of interest here, it is firmly connected to the container, the aerosol can, a bottle or the like.
  • a sealing ring 26 lies in a groove or recess in the bush 24.
  • the sleeve 24 also has a radially projecting collar 28. This forms an edge 30. This lies on a radial inward curvature the lid of the container, can or the like.
  • the joints 34 and the arms 36 extending from them are molded or molded onto the bushing 24.
  • the joints 34 are formed by material thinning.
  • the arms 36 have thickenings 38 at their radially inner ends, or they are joined to form a ring 38.
  • the rod 40 with the valve closure member 42 with the closing surface 44 lies centrally within the slide sleeve 12 and bush 24. At its lower end, it has a saving 46.
  • the thickenings 38 and the ring 38 are clamped into this.
  • Fig. 3 also shows the clamping ring 48, which can be used optionally.
  • the embodiment shown in FIG. 4 differs from that of FIG. 3 only in constructive details.
  • the sleeve 24 is combined with a sleeve 50, which surrounds it radially at a distance, to form a single component.
  • the sleeve 50 has an internal thread 52. So that it is screwed onto a neck 54 of a bottle or the like, which is also threaded.
  • the arms 36 have lugs 56. These rest on the complementarily shaped upper sides of the cutouts 18. This results in pivot bearings for the pivoting movement of the arms 36.
  • a sealing lip 60 is also formed on the outside of the slide sleeve 12.
  • FIGS. 4 and 5 also show the locking projections 68 at the ends of the webs 20.
  • the valve is seated on a container, an aerosol can or the like.
  • the space within the slide sleeve 12 is thus also under the pressure of the propellant via the space between the four arms 36.
  • the handle 14 is pressed to open the valve. This downward movement ends at the latest when the underside stops at the upper edge of the can lid 32 or the sleeve 50.
  • the pressure edges 22 on the upper side of the recesses 18 press against the arms 36 or the lugs 56 lower region of the sleeve 24 spread radially outwards.
  • the arms 36 also perform a movement. This consists of two components. One component is a linear movement axially downwards. The second component is a swivel movement. The center of this pivoting movement lies in the embodiment according to FIG. 3 in the joints 34 and in the embodiment according to FIG. 4 in the pivot bearings between the pressure edges 22 and the lugs 56.
  • the rod 40 follows the first movement component and moves downwards.
  • the valve closure member 42 moves away from the valve seat 16.
  • the valve opens.
  • the theoretical end position of this movement is indicated at the bottom left in Fig. 4.
  • An arm 36 is shown in a horizontal position in dash-dotted lines. This is the position of an arm 36 when the valve is fully open. With a comparative view of FIGS. 1 and 2, it can further be ascertained that the valve closure member 42 has moved down more than the valve seat 16 during this movement sequence, so that the valve opens.
  • the handle board 14 is released.
  • the elasticity and restoring force of the sleeve 24 comes into effect. In its lower region it contracts radially and assumes the position shown in FIGS. 3 and 4. Since the arms 36 enclose an acute angle with it even in the maximum open position, the arms pivot during this movement such that the rod 40 upwards and the valve closure member 42 is moved into the closed position. This radial inward movement of the lower region of the sleeve 24 is supported by the clamping ring 48, if it is present.

Abstract

Soupape pour bombe aerosol. Elle comporte un boitier (24), qui est fixe solidement, par une ouverture, dans une paroi du reservoir. Un manchon coulissant (12) se trouve concentriquement a l'interieur du boitier (24) et peut coulisser a l'interieur de celui-ci. A son extremite exterieure, ce manchon est ouvert et forme le siege de soupape (16). Ce siege de soupape peut etre obtenu au moyen d'un element de fermeture (42). Cet element de fermeture est monte sur une barre (40) placee concentriquement a l'interieur du manchon coulissant (12) et du boitier (24). L'extremite inferieure de cette barre est reliee d'une piece avec le boitier (24) au moyen de bras disposes radialement (36); ces bras penetrant par des ouvertures faites dans le fond du manchon coulissant (12). En appuyant sur le manchon coulissant (12), celui-ci appuie sur les bras (36) et libere l'element de fermeture (42). Par ce moyen, on supprime la force necessaire pour la fermeture, produite par l'elasticite du bras (36).
