Definitions

  • the invention relates to a dispenser for pasty masses (M), with a piston (2) which is displaceably arranged in the dispenser housing (1) and moves in the opposite direction when the dispenser is emptied, and which is blocked in the opposite direction, and a pushbutton actuating surface which is attached to a headpiece of the dispenser housing is provided, with the head piece being coupled to a rod (4) which passes through the piston (2) and which is non-positively coupled to the piston (2) with the interposition of a locking mechanism.
  • M dispenser for pasty masses
  • a donor of this type is known from DE-OS-3 045 048 by the applicant.
  • the piston forms the bottom end of the dispenser housing.
  • a measure securing the position of the membrane consists in an advantageous further development in that the membrane is clamped by means of a foot ring attached to the dispenser housing.
  • an advantageous feature of the invention results from the fact that the foot ring forms a bottom wall below the membrane and, in alignment with the piston rod, forms a passage opening for the latter.
  • 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 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 spike ends is somewhat larger than the clear diameter of the dispenser housing 1, as a result of which the spike ends, as inclined support feet, hook on the housing inner wall 1 'in a blocking manner against the direction of the arrow X.
  • the clamping module 3 forms a second locking mechanism G2 in the center.
  • a piston rod 4 which penetrates the piston 2 centrally, interacts with the latter.
  • the radially inwardly directed teeth 3 "of the clamping module 3 engage the piston rod 4. When projected into the plane, the passage opening left by the teeth 3" is smaller than the diameter of the piston rod 4.
  • the bottom end 4 'of the piston rod 4 is sharpened.
  • the tip is designed as a cone 4 ".
  • a movement of the coupling rod in the direction of arrow x leads to the entrainment of the piston 2 due to the non-positive coupling.
  • the dispenser housing 1 forms this entrainment of the piston on the base of the housing equipped with a foot ring 5 It is a bellows that can be compressed like a bellows in the direction of the piston 2 and straightens up to its basic position
  • the head piece 6 further forms a channel-like dispenser mouthpiece opening 8.
  • the latter is designed in the shape of a beak, and its preferably circular opening mouth is close to the direction of extension of the housing wall and is for the times closed the storage with the help of a tightly closing plug 9.
  • the stopper has the shape of a pot with the rim of the pot directed towards the mouthpiece opening. The plug is therefore highly flexible and its tight closure is optimized.
  • the head piece 6 furthermore forms a pushbutton actuation surface 10 in the back of the beak-like extension circumscribing the mouthpiece opening 8. The latter extends until just before the opposite, mentally extended housing wall level and rises outwards at an angle.
  • the piston rod 4 passing through the dispenser housing 1 in the longitudinal central axis y - y is connected to the head piece 6.
  • the head piece 6 forms, below this pushbutton actuation surface 10, a latching recess 11 directed into the housing, into which the mushroom head-like widened upper end 4 ′′ is snapped in.
  • the latching recess 11 forms a funnel-shaped extension on the piston side for easier clip assignment.
  • the piston rod has an annular bead 12.
  • the latter limits the actuation stroke H of the piston rod 4 by stepping against the top of a hub-like sleeve 13 in the neck 7 of the dispenser housing 1.
  • the sleeve is connected to the neck 7 via spoke-like radial ribs 14.
  • the guiding bushing 13 essentially closes with the top of the neck end and protrudes approximately halfway into the neck, i. H. into its opening.
  • a membrane 15 takes over the airtight seal in the bottom area of the dispenser housing, so that from there it is no longer possible to dry the pasty mass.
  • the membrane 15 is connected by gluing, heat sealing or the like to the front edge 1 "of the dispenser housing.
  • the membrane 15 is destroyed when the pushbutton actuation surface 10 is actuated.
  • the piston rod is designed as a puncture tool and fulfills a corresponding additional function (taper 4 ").
  • the taper tip lies at a distance z in front of the membrane 15 (see FIG. 3), which is smaller than the maximum, stop-defined Actuation stroke H of the piston rod 4. This results in a central perforation, so that the formation of a vacuum below the piston 2 is prevented.
  • the membrane 15 is clamped in place by means of the foot ring 5 fitted onto the dispenser housing.
  • the foot ring has the shape of a flat truncated cone on the outside. Its downward-facing, cylindrical standing edge 5 'brings a widened standing area for the dispenser and thus increased stability.
  • the plug-in assignment can be realized by opening the foot ring 5.
  • the outer surface of the cylindrical dispenser housing has an annular projection 16. The latter enters a matching annular groove 17.
  • the annular groove 17 is located in a likewise cylindrical ring wall 5 "of the foot ring, which merges into a horizontal bottom wall 5 '" below.
  • the inner edge portion is used for the peripheral clamping attachment, while the bottom wall 5 "'which extends immediately below the membrane 15' supports the membrane downwards.
  • the bottom wall 5 Aligned to the piston rod 4, the bottom wall 5 "'leaves a passage opening 18 for the piercing tool.
  • the bottom wall 5"' extends at such a vertical distance from the installation surface F, for example formed by a bracket, that the tip of the cone 4 "has this surface not touched, so the dispenser can be dispensed.
  • the lower end of the dispenser housing on the assignment side has a larger clear diameter than the longer remaining section of the same (see step 20).
  • the head piece 6 is covered by a cap 19.
  • the latter holds frictionally or positively on a peripheral bead in the fastening area thereof between the lower edge of the headpiece and the neck 7 of the dispenser housing 1.
  • the cylindrical inner wall 19 'of the cap 19 secures the position of the stopper 9 which is supported on it with its back.
