Definitions

  • the invention relates to a dispenser for pasty masses, with a housing having a piston which can only be displaced in the direction of emptying and an external actuation handle which is formed on a bellows which can be compressed in the direction of the piston and which has a dispenser outlet opening.
  • a donor of this type is known from DE-AS 12 10 149.
  • the piston is pulled by the vacuum, which forms in the housing when the head piece bellows is reset, over the filling material column in the direction of the head piece.
  • a valve is installed in the latter, which closes the opening mouth again as the overpressure drops.
  • the assignment of a corresponding dispensing valve is too complex for a mass article, such as a toothpaste dispenser pack.
  • malfunctions are to be expected, since the head bellows, which is formed from a correspondingly soft material and therefore can be changed considerably in shape, does not rule out a displacement of the spring means.
  • the dispensing valve is suddenly opened from a certain overpressure threshold, it can also lead to unpleasant spray effects and in any case not precisely meterable dispensing rates.
  • the object of the invention is to design a dispenser of the generic type in a construction which is simpler in terms of production technology and more advantageous in terms of use, in such a way that the dispensing valve mentioned is dispensable.
  • a dispenser of the generic type which does not need the classic so-called flutter valve, but nevertheless allows an exactly metered, user-friendly dispensing.
  • the valve function that can surprisingly still be achieved using the inertia of the pasty mass is also cheaper in that it no longer has to be generated first of all an overpressure opening the valve lips, which always brings about a more or less sudden, poorly controllable discharge of the contents.
  • a tube emerges from the dispenser outlet opening, and its inner mouth end remains immersed in the pasty mass in every position of the bellows.
  • the long, cylindrical housing 1 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 has a so-called clamping module 3 in the form of a radially oriented prongs 3 'having a star made of spring steel on its wide surface facing the housing end on the housing side. Its diameter circumscribing the serrated ends is larger than the inside diameter of the housing, as a result of which the serrated ends as an inclined support feet on the inside wall of the housing against the direction of the arrow x.
  • the output-side closure of the housing 1 forms an actuating handle attached to the base 4 of the same. It is a headpiece 5 that can be compressed like a bellows in the direction of the piston 2 and always spontaneously straightens up into its basic position. The latter is plugged onto the somewhat narrower neck 6 of the housing 1. A use-stable attachment is present via a ring groove engagement in cooperation with the restoring force of the material forming the head piece 5.
  • the head piece 5 forms a cross-section-reduced dispenser outlet opening ⁇ . From the latter, a tube 7 protrudes into the interior of the dome-shaped head piece 5.
  • the tube is made of a relatively rigid material and is gripped by a protuberance 8, which starts from the head piece cover 5 'and slopes upwards. The tube sits in the clamp, but can be glued or welded to the head piece if necessary.
  • the tube 7 is inclined at an acute angle to the longitudinal axis yy of the tubular or cylindrical housing 1. It projects with its outer mouth end 7 'forming the outlet opening ⁇ practically into the region of the extended jacket plane of the housing 1.
  • the inner mouth end 7 "extends up to the area of the longitudinal central axis yy, ie into the center of the rotationally symmetrical housing. It closes approximately at the same level with the upper neck edge 6 'and, as can be seen from FIG. 3, dips into the pasty mass M with this inner mouth end 7 ", which extends to below the dome-shaped ceiling 5 'of the head piece 5 is sufficient, thus also surrounding the tube on its entire circumference. Moreover is always a partial length of the tube 7 filled with pasty mass.
  • the angle of inclination alpha is approx. 30 °.
  • the zone forming the bellows B of the head piece 5 is achieved by means of a horizontal, flat, V-shaped constriction E. This constriction extends over half the cross-sectional width of the head piece 5 which tapers like a truncated cone in its basic shape.
  • the bellows groove is designated by 9 and illustrated in FIG. 1 in dashed lines.
  • the acute-angled assignment of the tube 7 in the part of the head piece 5 opposite the indentation E is such that the tube 7 tilts into a coaxial or approximately coaxial or spatially parallel position to the longitudinal center axis y-y of the housing 1 when the bellows is actuated.
  • the outer mouth end 7 'of the tube 7 moves away from its basic position close to the edge.
  • the mouth end 7 'can also be designed in a more beak-shaped shape such that the opening ⁇ is perpendicular to the axis y-y.
  • the head piece 5 is covered by a cap 10.
  • the inner corner of the cap cover is beveled in accordance with the end face position of the tube, so that when the cap 10 is angled, the tube opening is tightly closed.
  • the cap 10 holds frictionally or positively on a peripheral bead in the fastening area thereof between the lower edge of the head piece and the neck 6 of the housing 1.
  • the dispenser described works as follows: after the cap 10 has been removed, the head piece 5 in the region forming the bellows B, which is grooved on the top side or roughened in some other way, is pressed downward in the direction of the piston 2.
  • the piston 2 is supported by the clamping module 3 so that it cannot deflect downwards.
  • the pasty mass M pushes through the tube 7 in the direction of the opening ⁇ and finally emerges from the mouth end 7 '.
  • negative pressure is created inside the housing.
  • the the flexible head piece 5 returning to its basic position pulls the piston in the direction of the arrow x over the filling material column. This resetting is completed before the mass remaining in the tube could reach the inner mouth end 7 "as a stopper.
  • the decisive factor here is that the cross-section and length of the tube 7 form a corresponding resistance in coordination with the viscosity of the pasty mass and the flow rate that has occurred that bridges the vacuum that occurs.
  • the ratio of clear tube cross-section to tube length is approx. 1: 5.
