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.
  • They are opened by pushing or pushing a part inwards. They also contain a special spring or a spring element made of metal, rubber or an elastic plastic, which presses the closure member against the valve seat in the closed position. The pressure to open the valve is then against the pressure of this spring element.
  • valve seat is not on the outside, but on the inside, so that air can get into the interior of the cup-shaped membrane from the outside, even in the closed position, where it can react undesirably with liquid that is always present when used.
  • 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 dispensed with, not only is there no component, its manufacture and assembly, but there is also the possibility of working without metal or a plastic selected for 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.
  • points B and C have covered different distances.
  • the stretch BD is smaller than the stretch 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 the point C and the valve seat G to the point B of the imaginary lever AC.
  • 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 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 this moves the arms in their radial inward movement - when looking at FIGS. 1 and 2 - upwards or in the closed position of the closure member. The valve thus automatically returns to its closed position after opening.
  • the sleeve with the joints and the arms is formed (molded) as one part, the joints with the arms being molded onto the lower end of the sleeve.
  • the joints with the arms being molded onto the lower end of the sleeve.
  • four arms will be used. However, three, five or another number of arms are also conceivable.
  • the rod has an annular recess 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 recess 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, such that the arms passed through the recesses rest on the webs and are clamped between them, a lateral and upper limit of the recess and a latching 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 top edge of the sleeve or the can lid holding it, which is the maximum len stroke of the rod corresponds.
  • the grip board is thus both a handle for pushing down the slide sleeve and a stop for limiting the stroke.
  • lugs are provided on the arms, and the upper sides of the recesses are shaped such that they form a pivot bearing with the lugs 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 therein.
  • a sealing lip abutting the sleeve is formed on the outer wall of the slide sleeve in the region enclosed by the sleeve.
  • an alternative embodiment provides that the rod is connected in one piece to the arms via joints designed as material thinnings.
  • the valve closure member is a special component which 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 at a radial distance within a sleeve connected to it in one piece and that it can be placed pressure-tight on a container or the like.
  • the bushing 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. 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 cutouts 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 encloses 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 against a radial inward curvature of the lid of the container, the can or the like.
  • the joints 34 and the arms 36 extending from them are molded or injection molded onto the bushing 24. The joints 34 are formed by thinning the material. At their radially inner ends, the arms 36 have thickenings 38 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 the bush 24. At its lower end, it has a saving 46.
  • the thickenings 38 and the ring 38 are clamped into these.
  • Fig. Furthermore shows the clamping ring 48, which can be used optionally.
  • the embodiment shown in FIG. 4 differs from that according to 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. It is thus screwed onto a neck 54 of a bottle or the like, which also has a thread.
  • the arms 36 have lugs 56. These are on the complementarily shaped tops of the Aus savings of 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.
  • the rod 40 is also integrally connected to the arms 36 and thus the bushing 24. Between the rod 40 and the arms 36 there are thinnings of material which form the joints 62. However, the valve closure member 42 is now a separate component. It is pushed onto the rod 40 and latched to it via a tongue and groove connection 64. 4 and 5 still show the locking projections 68 at the ends of the webs 20th
  • the handle board 14 is released.
  • the elasticity and restoring force of the sleeve 24 comes into effect. In its lower area 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 in such a way that the rod 40 is moved upward 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.
