  • the head piece 3 has a portioning chamber 18. This is arranged at least in the unloaded position of the head piece 3 substantially above the supplementaryteil- or mass housing side pipe section 9. Circumferentially, with respect to the axis x, the portioning chamber 18 is essentially delimited by the annular wall 16, which annular wall 16 has a thickening in the region of the portioning chamber 18. An upper-side boundary of the portioning chamber 18 is provided by a head piece cover 19, which at the same time offers a control surface for the preferred finger-loaded pressure load of the head piece 3 for dispensing the mass M.
  • the portioning chamber 18 opens substantially at least radially outward into a mouthpiece channel 20.
  • an outlet opening 21 is formed in the mouthpiece channel 20 associated region of the annular wall 16 and the headpiece side thickening, which compared to the inner diameter of the mouthpiece channel 20 is reduced diameter.
  • a central axis of the mouthpiece channel 20 is further preferably in parallel alignment with an actuation plane of the headpiece cover 19 preferably, as also shown, an acute angle to a, relative to the axis x, considered transverse plane of 10 to 15 ° including.
  • the mouthpiece channel 20 facing the outlet opening 21 surrounding contact surface 22 extends with respect to a vertical cross-section at an acute angle of 5 to 7 ° to a plane parallel to the axis x extending vertical plane.

  • the spring element 25 is for this purpose made of a rubber-like, resilient plastic, more preferably made of a silicone material.
  • spring element 25 is initially and substantially rotationally symmetrical design and has centrally first a pot-shaped fixing portion 26, with a transverse to the axis x in the installed state aligned ceiling 27 and one of the ceiling 27 outgoing and downward, circumferential wall.
  • a further, annular wall is provided, wherein both walls with respect to a vertical cross section U-legs 28, 29 which are interconnected via a U-bend 30, this at a U-opening, the in the installed position of the spring element 25 upwards in the direction of the portioning chamber 18 points.
  • the spring element 25 is held in the region of the pipe blanket 10, for which purpose a circumferential, free web portion 31 of the pipe section 9 from below engages in a formed in the region of the radially inner U-leg 28 of the spring element 25 annular slot.
  • the U-leg 28 is in this case substantially and circumferentially on the Wandungsau.
  • Both U-legs 28 and 29 are due to the above-described arrangement and training between the two parallel ring walls 16 and 32 of the head piece 3 and mass housing 2 or insert 6, so that in the course of the downward displacement of the head piece 3 according to pressurization on the headstock cover 19 a unwinding or rolling up of the U-legs 28 and 29 along the associated ring walls 16, 32 is achieved.
  • the spring element 25 acts according to a rolling bellows. In the course of a user-operated downward displacement of the head piece 3, a spring force is built on the rolling bellows-like spring element 25, which is used for the automatic return of the head piece 3 in the initial position after canceling the pressure load from the outside.
  • the radially inner U-leg 28 is material-reinforced relative to the radially outer U-leg 29, this further in particular with respect to an operationally unloaded basic position according to Fig. 2 starting from the ceiling 27 of the spring element 25 up to reaching the U-vertex in the region of the U-bend 30.
  • the U-leg 28 is provided with a material thickness which is about 1.5 to 2 times the material thickness of the radially outer U-leg 29 corresponds.
  • the spring element 25 is formed in one piece and of the same material both with an outlet valve 34 and with an inlet valve 35.
  • the inlet valve 35 it is a substantially plate-shaped in the area of the ceiling 27 of the fixing portion 26 valve with a centrally disposed, movably supported by webs 36 cone closure body 37. The latter closes in a normal position of the dispenser 1 sealing the inlet opening 11 of the mass housing side pipe section 9, wherein the conical closure body 37 supporting webs 36 substantially, at least partially supported on the top of the pipe blanket 10.
  • This is designed as a pivotable sealing tongue 38, which projects from the formed by the radially outer U-leg 29 circumferential edge 33 with respect to a vertical section in extension of the U-leg 29.
  • This sealing tongue 38 is material-tapered with respect to the U-leg 29 carrying it, preferably has a material thickness which corresponds to 0.5 to 0.8 times the material thickness of the U-leg 29.
  • the sealing tongue 38 dives into the mouthpiece channel 20 through a slot formed in the connecting region of the U-leg 29 in the thickening section of the annular wall 16, for abutment of the sealing surface facing the outlet opening 21 against the contact surface 22 surrounding the outlet opening 21.
  • the sealing tongue 28 against the unloaded orientation of the sealing tongue 38 in the non-installed state resiliently loaded in the direction of the closed position of the outlet opening 21 at.
  • Fig. 3 to 5 are positions of the donor 1 shown in the course of a first use. It can be seen that as shown in Fig. 3 before a first use mass M is only in the mass housing 2. It is accordingly first to perform a first filling of the portioning chamber 18. This is done by usual operation of the head piece 3, by this according to pressurization in the direction of arrow P down relative to the mass housing 2 is displaced, this further against the force of the spring element 25, which automatically causes a reset of the head piece 3 in the starting position after canceling the pressure load. In the course of this backward displacement into the initial position, the mass M is drawn into the portioning chamber 18, with a corresponding displacement of the inlet valve 35 or the cone closure body 37, into a position M releasing the inlet opening 11. For complete filling of the portioning chamber 18 as shown in FIG Fig. 5 is preferably a 2 to 3 times operation of the head piece 3 (pumping operation) necessary.
  • dispenser 1 is ready for the first portioned output of mass M.
  • a portioned mass issue is in Fig. 6 shown.
  • the mass M under oppressive pivotal displacement of the sealing tongue 38 of the outlet 34 through the outlet port 21 and the mouthpiece channel 20 to the outside for removal in the area Dispensing opening 23 transported.
  • the sealing tongue 38 bends into the flow of the mass M, this more preferably and starting from the foot-side connection region to the edge 33 of the spring element 25 under arcuate deflection considered in vertical section.
  • a dispensing volume of mass M of 0.8 to 1.5 ml is preferably achieved.
  • the spring force of the spring element 25 built up during the downward displacement of the head piece 3 is used for the automatic return displacement of the head piece 3 into the in Fig. 6 represented starting position of the head piece 3, wherein in the course of the backward displacement due to suction, the portioning chamber 18 is filled again with mass M, this with a corresponding displacement of the outlet valve 34 in the release position.
  • the sealing tongue 38 is displaced back into the closed position of the outlet opening 21, which displacement is further assisted by the suction effect which occurs during the return displacement of the head piece 3, which also advantageously at least partially draws in in the mouthpiece channel 20 remaining mass M causes.
  • This suction-return displacement of remaining in the mouthpiece channel 20 remaining amount of mass M supports the return displacement of the sealing tongue 38 in the closed position.
  • the portioning chamber 18 is filled up to the circumferential U-region of the spring element 25 with mass M. Due to the spring element material, diffusion may occur, in particular in the case of a longer service life of the dispenser 1, which is thus in readiness. This negative effect is counteracted by the substantially reduced compared to the solution of the prior art diffusion surface of the spring element 25. In this case, the diffusion surface extends only over the immediate region of the U-bend 30 of the spring element 25. All other regions of the spring element 25 are at least rearward, ie facing away from the mass M, covered with material, so that diffusion is counteracted over these regions. Further areas of the spring element 25 are covered in particular in the ready position of the dispenser 1 on both sides of mass M.
  • Fig. 8 shows the emptying position of the dispenser 1, in which the trailing in the course of each dispenser piston 7 occurs in a stop position with the insert 6, wherein the trailing-piston pipe section 13 is immersed in the pipe section 9 of the insert 6. It is in Fig. 8 shown a position in which the portioning chamber 18 is still completely filled, according to still allows the issue of a portioned amount of mass M.
  • the proposed dispenser 1 has a low residual emptying amount of preferably less than 2.6 ml.
