Definitions

  • the invention relates to a dispenser according to the preamble of claim 1.
  • a dispenser of this type is known from U.S. Patent 3,255,935.
  • the angle leg forming the actuating handle extends freely projecting in front of the casing wall of the housing. Since the swivel stroke directed against the housing requires a not inconsiderable amount of space, there is a fairly large projection for this angle leg.
  • a leaf spring is housed in the tilting space. Apart from the fact that this solution is aesthetically unsatisfactory, there is a risk of the user getting stuck. In addition, objects can get caught in the hook-like board.
  • the angled arm extending through the window-shaped opening, oriented transversely to the longitudinal axis of the piston rod and engaging thereon, pulls the piston rod back when the angled lever is actuated, with the mouthpiece opening being released;
  • the active dispensing stroke is brought about by the return spring, in that the piston rod carries the piston along with the locking mechanism and thus presses out the filling content in a metered manner.
  • this requires the use of an extremely strong spring, which is detrimental to the ease of use of the dispenser.
  • FR-PS 797 113 it is already known on a dispenser which differs in the genus to advance the piston rod plus piston during the actuation stroke in the dispensing direction; but this solution sees one coaxial push button located in the bottom area.
  • this mechanism is too complex for a mass article. It provides a screw-in floor. The latter forms a receiving chamber for the return spring. The chamber must then be closed by creating a spring abutment with the help of an intermediate piece that is also screwed in.
  • the push button located in a depression in the base surface offers only a relatively small pressure surface.
  • the object of the invention is to provide a generic dispenser with regard to the actuating mechanism in a technically simple, more advantageous manner in such a way that, on the one hand, safe operation of the dispenser is possible, but on the other hand the more economical angle lever solution can be retained.
  • the angled leg forming the actuating handle is fully freely accessible as far as its tactile surface is concerned.
  • the side surfaces are framed by the wall material of the housing. Pinching the fingers of the operating hand is excluded, as is the possibility of objects getting caught on the angle lever.
  • the frame can be chosen so that the window-shaped opening can even be used as a guide for the tiltable angle lever.
  • An advantageous embodiment is further achieved in that the transverse axis of the angle lever is closer to the mouthpiece than the free actuating end of the angle lever and the angle leg directed transversely to the longitudinal axis pivots when actuated in the direction of the mouthpiece.
  • the working stroke results from the push-in movement of the angle lever.
  • This is cheaper in that you can generally apply much higher forces by hand than with a return spring of this size.
  • This only needs to move the piston rod and the angle lever coupled to it back into the starting position. It can even be made weaker in that it no longer has to move the piston plus level column.
  • the spring can also be conveniently incorporated into the dispenser simply by using the space between the angle leg lying parallel to the longitudinal axis of the housing and the inner surface of the housing wall opposite the window. It is simply clamped in the space provided for the angle lever between the angle leg and the housing wall.
  • a technically advantageous coupling between the piston rod and the angle lever results from the fact that the angle leg of the angle lever directed transversely to the longitudinal axis engages in a ring-shaped manner in an annular groove of the piston rod.
  • the axis of the angle lever can be easily realized by stub axles that snap into place on the housing.
  • the mouthpiece is arranged on a cap placed on the front end of the housing. This measure also results in the further advantage of adapting the dispenser to contents of different viscosity, the basic type of dispenser being able to be maintained and only the cap having the different cross section needing to be replaced.
  • the procedure is further such that an intermediate floor of the housing is provided at the level of the frame leg of the window closest to the mouthpiece, with a guide bore for the piston rod. It is thus still axially centered in the coupling area towards the angle lever when the piston, which generally acts in a self-centering manner, is already in the mouth area of the dispenser is wandering.
  • This intermediate floor also fulfills another function in that it forms the end stops for the movement of the angle lever.
  • the procedure here is such that the stops are formed by partial surfaces of a roof-like shape of the upper end face of the angle lever which extend on both sides of the transverse axis.
  • the thickness of the angled arm extending parallel to the longitudinal axis is greater than the swivel stroke and that of the angled arm extending transversely to the longitudinal axis.
  • this thickened area to form a spring receptacle, which expediently takes the form of a blind bore.
  • the dispenser has a cylindrical housing 1 made of plastic. This ends on the output side with a considerably reduced cross-section mouthpiece 2. The latter is based on a cover 3. The cover extends over the front end 4 of the housing 1. It can be assigned by means of the clip connection (not shown).
  • the other end 5 of the housing ends with a bottom 6.
  • An intermediate floor 7 extends at a distance x from this. This distance corresponds approximately to a quarter of the length of the cylindrical receiving chamber 8 for the pasty mass M.
  • This mass is discharged via a piston 9 as a press base.
  • the running surface merges into ring lips 10 on both sides, which lead sealingly on the cylindrical housing inner wall 1 '.
  • the piston 9 is placed on a central piston rod 11 and is only slidably mounted thereon in the direction of the mouthpiece 2.
  • the piston rod 11 itself can be axially displaced to a limited extent in both directions by actuating an angle lever H arranged in the base region.
  • the bottom locking of the piston is achieved via a one-way locking mechanism 12 (see FIGS. 5 and 6).
  • the latter consists of a spring washer 13 stamped from thin sheet steel. This has radially inwardly directed tongues 14.
  • the tongues 14 extend in the same angular distribution and are bent with respect to the transverse plane corresponding to the piston position in such a way that their end edges 14 'are under spring tension Support on the lateral surface of the piston rod 11 offset in level. Its sloping rise faces the direction of the mouthpiece.
  • the piston rod 11 is displaced in the direction of the base 6, the end edges 14 'of the tongues 14 slide over the outer surface.
  • the piston 9 is carried along via the same tongues 14.
  • the outer wall of the piston rod is roughened, in particular equipped with transverse grooves 15.
  • the fixing of the locking mechanism 12 on the piston 9 is achieved by means of spring tongues 16 directed radially outwards, which likewise claw on the wall 17 'of a cup-shaped recess 17 with a slight bend.
  • the angle lever H coupled to the piston rod 11 pivots about an axis z-z lying transversely to the longitudinal axis y-y of the dispenser.
  • One angle leg a extends transversely to the longitudinal axis y-y, while the other angle leg b runs parallel to the named longitudinal axis.
  • the transverse axis z-z of the angle lever H is closer to the mouthpiece 2 than the free actuating end E of the angle lever b.
  • the angle leg a directed transversely to the longitudinal axis y-y pivots in the direction of the mouthpiece 2 when actuated while driving the piston rod 11 and the piston 9 (cf. FIG. 5).
  • the mass 8 is thus applied during the actuation stroke of the angle lever.
  • the return of the piston rod to the rest position shown in FIG. 3, however, is spring-initiated.
  • the compression spring loading the angle leg b is designated by 18.
  • Spring 18 and angle lever H are received in a transverse shaft 19 extending from the jacket wall. Its opening 20 frames the side surfaces S 1 to S 4 of the angle leg b extending parallel to the longitudinal axis y-y of the housing. This framing leaves the slightly protruding key area available for operation over the entire surface and avoids the risk of the fingers of the operating hand being caught. Even when this actuating handle is pressed in, there is no danger, since the thickness of the angle leg b extending parallel to the longitudinal axis y-y is greater than the pivoting stroke of the angle lever H.
  • the angle leg a on the other hand, has a substantially reduced thickness d. Its free end merges into a holding fork 21.
  • the clutch takes into account a certain amount of play, which takes into account the tilting displacement.
  • the width of the two angle legs is kept the same, so that the angle lever H can easily guide against the shaft walls 19 'running in the longitudinal direction of the dispenser.
  • the transverse axis z-z is formed by wart-like stub axles 23 formed in the apex region of the two angle legs, which are snapped into corresponding bearing cavities in the parallel shaft walls 19 '.
  • the receiving chamber 8 and transverse shaft 19 spatially separating intermediate floor 7 is used to form stops for the movement of the angle lever H.
  • the corresponding end face consequently has a roof-like shape with a roof ridge line 25 lying in the region of the transverse axis and running parallel to this.
  • the guide bore 26 contributes to securing the coupling between the piston rod 11 and the angle lever H, so that the coupling is simply in the way of a radial plug connection of the angle lever H can be brought about, this in conjunction with the latching connection of the axle stub 23.
  • the dome or wart shape of the axle stub makes special run-up slopes unnecessary.
  • the material of the housing 1 is set so flexibly that the stub axles can snap in without damage.
  • the compression spring 18 loading the angle lever H in the basic position is clamped in the space between the angle leg b parallel to the longitudinal axis yy of the housing 1 and the inner surface of the housing wall 1 ′′ opposite the window-shaped opening 20 Holding pin 27 is plugged on, the other spring end rests in a cup-shaped recess 28 of the angle leg b which is of sufficient thickness for this purpose.
  • the outside of the angle leg b forming the touch surface has a transverse recess 29 for inserting the fingers of the actuating hand.
  • the transverse trough 29 runs over clearly convex curves 30 into the partial surface 24 or an approximately parallel end surface 31 at the free end of this leg.
  • the rounding essentially ends at the level of the frame edge.
  • the touch surface is also broken in the transverse direction (see FIG. 2).
  • the end region 11 ′ there of the piston rod 11 is offset in cross section. In the end position on the mouthpiece side, the locking mechanism 12 therefore enters a release position.
  • the dispenser is assembled as follows: First, the piston 9 is inserted into the receiving chamber 8 until it rests on the intermediate floor 7. The piston rod is inserted from the mouth end until it protrudes into the transverse shaft 19 with its end having the annular groove. Thereafter, only the angle lever H previously equipped with the compression spring needs to be inserted into the shaft, the holding fork 21 engaging with the piston rod 11. This also results in the axis angle of the angle lever H.
  • the dispenser prepared in this way can now be filled across the full cross-sectional width. Then all you have to do is open or snap on the cap.
  • a dispenser of this type can also be refilled due to the simple assignment of the functional parts to one another, and it is useful for pushing out the angle lever, which acts as a locking bolt, if the wall having the holding pin 27 has an opening for inserting a notching tool (pencil or the like).
  • the piston can be removed anyway due to the release position. It is then only necessary to proceed as described above.
