Definitions

  • the invention relates to a dispenser for pasty masses, with a displaceably arranged in the dispenser housing, migrating in the direction of the mouthpiece opening when the dispenser is emptied, piston blocked in the opposite direction by a locking mechanism, a pushbutton actuation surface which is provided on a compressible headpiece of the dispenser housing, and a rod passing through the piston and coupled to the head piece, which is non-positively coupled to the piston with the interposition of a second locking mechanism working counter to the first locking mechanism.
  • a dispenser of this type is known from US-A-3255935.
  • the compressible head piece consists of a flat dome-like cap of elastic material assigned to the dispenser housing.
  • the latter has a radially directed mouthpiece opening.
  • the mouthpiece consists of a tube-like extension of the cap.
  • the tube can shift undesirably with respect to the target direction, so that the application of toothpaste, for example, to the rather small receiving surface of the brush is very difficult.
  • dispensers of this type have the disadvantage that when the actuation is complete, the contents of the filling continue to run out of the mouthpiece opening. This can lead to the end zone of the pasty mass drying out. When the stopper is loosened, an uncontrolled amount suddenly shoots out, again while keeping the target direction difficult.
  • the object of the invention is to design a generic dispenser in a production-technically simpler, more advantageous design in such a way that there is no more run-on with the usual dispensing quantities, that is to say the above-mentioned excess drying out before the mouthpiece opening is avoided.
  • a dispenser of the generic type is created, in which there is the essential advantage in use that after actuation has ended, no more protrusion forms in front of the mouthpiece opening; rather, the inventive pasty residual mass is drawn back into the mouthpiece opening by the configuration according to the invention.
  • the inventive pasty residual mass is drawn back into the mouthpiece opening by the configuration according to the invention.
  • it is directly connected to the contents and cannot dry out due to the moisture connection.
  • the corresponding clearance brings a shorter stroke of the piston, which is pulled over the rod and pushes the pasty mass, compared to a relatively larger actuation stroke of the bellows-compressible head piece, which leads to the suction effect which draws in the excess.
  • the structural means are simple and easy to assemble: the rod has a tapered section with a widened end piece at its head end, which lies in a chamber of the head piece arranged below the pushbutton actuation area. It is underneath the chamber floor and has a lower height than the chamber for realizing the access.
  • a simple assignment is that the end piece can be clipped in through the opening of the chamber bottom.
  • the long, cylindrical housing 1 of the dispenser contains a piston 2. Its edge lips 2 'lead to the cylindrical housing inner wall 1'.
  • the housing 1 is open at the bottom.
  • the piston 2 can only be displaced in the direction of emptying (arrow x). It carries a first locking mechanism G1 on its broad surface facing the housing end on the installation side. It is a so-called clamping module 3 in the form of a radially oriented tooth 3 'having a star made of spring steel. Its diameter circumscribing the serrated ends is somewhat larger than the inside diameter of the housing, as a result of which the serrated ends hook on the housing inner wall 1 'in the opposite direction of the arrow x as inclined support feet.
  • This clamping module 3 forms a second locking mechanism G2 in the center.
  • a rod 4 which penetrates the piston 2 centrally, interacts with the latter.
  • the inward points 3 " attack on the rod 4 formed by a smooth rod. Projected into the plane, the passage opening left by the prongs 3 ′′ is smaller than the diameter of the rod 4.
  • the bottom end of the rod 4 is pointed A rod movement in the direction of arrow x, on the other hand, leads to the piston being driven due to the frictional coupling. 2.
  • the housing 1 forms an actuating handle on the side opposite the base 5 of the same. It is a headpiece 6 which can be compressed like a bellows in the direction of the piston 2 and rises again into its basic position. The latter is plugged onto the somewhat narrower neck 7 of the housing 1. Via a ring groove engagement in cooperation with the restoring force of the material forming the head piece 6 there is a use-stable attachment.
  • the head piece 6 forms a cross-section-reduced, channel-like dispenser mouthpiece opening 8. This is beak-shaped. Its preferably circular opening mouth lies in the vicinity of the extended direction of extension of the housing wall and can be closed with the aid of a plug 9 for storage times.
  • the head piece 6 also forms a pushbutton actuating surface 10 in the back of the beak-like extension circumscribing the mouthpiece opening. The latter extends to just before the opposite, mentally extended housing wall level and rises outwards at an angle.
  • the rod 4 passing through the entire housing 1 in the longitudinal central axis z-z is connected to the head piece 6.
  • the head piece 6 is formed below this pushbutton actuation surface 10 in the direction of the housing in the direction of a chamber 11. Its bottom 12 leaves an opening 13 through which the mushroom-head widened end piece 4 'of the rod 4 is inserted.
  • the assignment is realized as a clip connection, i.e. the widened end piece 4 'is gripped by the chamber bottom 12.
  • the rod 4 forms a tapered section 4 ′′ at its end on the head piece side. This has the advantage that a continuous rod cross section can be assumed for the formation of the end piece 4 ′.
  • the opening 13 widens on the piston side in a funnel shape, so that despite the reduction in cross-section in the clip area, the rod 4 and the head piece 6 are securely bonded to one another.
  • the end piece 4 ' has a lower height h than the height H of the chamber 11 lying in the direction of rod displacement. This leads to an idle stroke upstream of the actual actuation stroke of the rod 4.
  • the mode of operation is as follows: the ready position given after the plug 9 is removed leads to the bellows-like compression of the practically dome-shaped head piece 6 displacing the portion of the pasty mass M present in the head piece, with the usual output amount being applied. However, this is only the case if, after passing through this empty stroke (clearance y), the rod 4 is also displaced by a so-called working stroke counter to the direction of the arrow x, that is to say in the direction of the ground. Due to the resetting of the head piece after the head piece has been released, the quantity dispensed is supplemented again by lifting the piston 2.
  • the dispensing residue protruding through the mouthpiece opening 8 is always withdrawn immediately, that is to say beforehand. There is therefore no residue left to dry out due to the surrounding outside air. Accordingly, no hardening stopper is formed. Rather, the portion drawn back into the lower region of the mouthpiece channel is directly connected to the moist supply.
  • accidental touches of the pushbutton actuation area by the amount of the clearance y do not result in the contents being output.
  • the corresponding idle stroke is slightly less than 1 mm in the size ratios shown in the drawing. If the piston area is larger and the working stroke is the same due to the push button actuation area 10, the idle stroke y must be given an appropriate increase.
  • the head piece 6 is covered by a cap 14.
  • the latter holds frictionally or positively on a peripheral bead in the area of attachment thereof between the lower edge of the headpiece and the neck of the housing 1.
