Definitions

  • the invention relates to a dispenser for pasty masses, with a housing which has a piston which can only be displaced in the direction of emptying and an external actuating handle which is formed on a bellows which can be compressed in the direction of the piston and which has a dispenser outlet opening, directed inwards a tube that is freely immersed in the pasty mass with its inner mouth end in every position of the bellows.
  • a donor of this type is known from DE-OS-3 042 285.
  • the pasty mass in the tube acts as a valve.
  • the pulling of the piston over the product column takes place primarily. H. before the remaining amount in the tube, which acts like a stopper, could balance the vacuum with air.
  • the piston is locked in the other direction by using a so-called clamping module.
  • the latter is attached to the wide surface of the piston facing the housing end on the installation side; it is a multi-pointed star-shaped component made of spring steel.
  • the diameter circumscribing the serrated ends is larger than the inside diameter of the housing, as a result of which the serrated ends hook onto the inner wall of the housing as inclined support feet.
  • Such a component is relatively complex for a disposable mass article.
  • Another assembly step is also created.
  • relatively high frictional forces have to be overcome, which places certain limits on the viscosity.
  • the object of the invention is to provide a generic dispenser in a technically simple, stable design so that the one-sided displacement of the piston is realized without components on the piston.
  • the structural means are simple in that a flap valve is located below the inner mouth end of the tube in the ceiling of the housing, from which a collar for the bellows extends, with a passage opening lying in the direction of the tube.
  • a flap valve can be easily molded onto the functional part.
  • the economy is high.
  • significantly lower frictional forces occur on the piston, which also benefits functional reliability and also allows the use of a wide range of contents with regard to viscosity.
  • the maximum length of the bellows interior is used for the tube, and on the other hand, this assignment also results in a certain actuation end stop for the bellows over the tube.
  • a largely loss-free output can be achieved with simple means in that the piston forms on its upper side a flat wall running parallel to the housing cover that centrally supports the valve flap. The upper side expediently closes off with one of the usual edge lips of the piston.
  • valve flap valve design it is expedient to proceed in such a way that the valve flap of the housing cover is integrally formed on the periphery of the same material over a thinned cross-section, according to which a pretension is inherent when the valve flap is sprayed in the vertical position facing the housing and through threading through the passage opening.
  • the valve flap is always safely loaded solely from the restoring force inherent in the material in the closing direction.
  • there is the, albeit low, weight of the valve flap taking into account the normally occurring position of use.
  • 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 from the inside, but can be closed by means of a clip-in base plate 3.
  • the output-side closure of the housing 1 is formed by an actuating handle H arranged opposite the widened base base 4 of the same. It is a bellows-type headpiece 5 that can be compressed in the direction of the piston 2 and always spontaneously straightens up to its basic position. The latter is on a housing 1 narrowed collar 6 attached. A thread-stable or ring-groove engagement in cooperation with the restoring force of the flexible material forming the head piece 5 provides a stable connection between the two parts.
  • the head piece 5 forms a cross-section-reduced dispenser outlet opening O.
  • a tube 7 protruding from the latter extends into the interior R 1 of the dome-shaped head piece 5. With its end on the outlet opening side, it is rooted close to the edge both in the ceiling 5 'of the head piece 5 and partly in the wall 5 "thereof. This wall 5" is slightly fitted.
  • the tube merges into a protrusion 7 "'formed by the head piece 5, the ceiling 5, which is somewhat superior.
  • the tube 7 extends at an acute angle to the longitudinal center axis yy of the tubular or cylindrical housing 1. The angle designated by alpha is approximately 25 °.
  • the tube can also run parallel to the axis yy, which would be cheaper in terms of injection technology.
  • the tube protrudes almost into the region of the extended jacket plane of the housing 1.
  • the inner mouth end 7 " points essentially into the center of an interior R1 of the head piece 5 from the storage space R 2 of the housing 1 partitioning ceiling 8.
  • the latter extends parallel to the base St and is molded onto the housing 1.
  • the distance between the inner end of the mouth 7 "and the top of the ceiling 8 corresponds approximately to the inside diameter of the tube 7.
  • the inner mouth end section of the tube 7 extends in an overlap with the curb 6.
  • a flap valve 9 In the middle area of the ceiling 8 there is a flap valve 9. The latter extends over the edge of a passage opening 10 of the ceiling 8.
  • the outline shape of the folding valve 9 results from FIG. 4.
  • the outline shape of the passage opening is designed accordingly.
  • the valve flap 9 ' occurs as a molding on the ceiling.
  • the hinge point is formed by a thinned cross section, a so-called film hinge.
  • the film hinge 11 extends over the entire width of the valve flap 9 ', all of whose edges are chamfered.
  • there is a thin-lipped edge which lies on the hole edge 10 'of the passage opening 10, which is also thinned by the wall.
  • valve flap 9 'of the housing cover 8 is molded during the injection molding process in the vertical position directed towards the contact surface St (see FIG. 3, alignment in solid lines), followed by after the hardening, the flexible valve flap 9 'is threaded through the valve hole 10. 90 ° are used to form the preload. This orientation is also favorable in terms of injection technology. No cross slides need to be attached.
  • a slightly roof-shaped profile is selected, as can be seen from the sectional illustration in FIG. 2.
  • the ridge line 12 runs parallel to the direction of extension of the film hinge 11.
  • the ridge line crosses the longitudinal center line y-y.
  • the piston 2 forms on its upper side a flat wall 13 which runs parallel to the housing cover 8 which centrally supports the valve flap 9 '.
  • the latter is part of a cover-side protuberance of a piston middle wall 14, which is rooted in the cylindrical section of the piston in the middle between the ring planes of the edge lips 2 ', 2 ".
  • this dispenser can be reused with a corresponding pulling device on the piston 2, i. H. refill from a larger storage container.
  • the base plate 3 must first be removed.
  • the piston 2 can be easily reintroduced by correspondingly chamfering the region of the housing inner wall 1 'near the bottom.
  • the base plate 3 contains an opening, which can also be used as a pulling aid.
  • the zone forming the bellows 6 of the head piece 5 is achieved by a horizontal, flat V-shaped constriction E. This constriction extends over half the cross-sectional width of the head piece 5 on the side facing away from the opening ⁇ .
  • the bellows groove is designated 15 (Fig. 2).
  • the acute-angled assignment of the tube 7 in the part of the head piece opposite the indentation E is such that the When the bellows is actuated, the tube swings out peripherally from the area of the valve flap 9 which is at a distance and flips up and practically tilts into a position parallel to the longitudinal center axis yy.
  • the section of the curb 6 there can serve as a stop.
  • the film hinge is located at a distance corresponding to the tube diameter from the section of the curb 6 there.
  • the head piece 5 is covered by a cover cap 16.
  • the latter has an outer diameter which corresponds to that of the housing 1. This results in a smooth continuation of the cylindrical shape up to the cap area.
  • the cover cap 16 can be clipped on.
  • the corresponding means are molded on the edge and interact with those of the head piece edge.
  • the cover cap has a further development in that it is included in the securing of a sealing plug 17, which is inserted into the dispenser outlet opening ⁇ , in that a portion 18 'of an annular rib 18 formed on the inner surface of the cup-shaped cover cap acts on the plug back. This back is inclined, the end face of the annular rib 18 is chamfered accordingly.
  • the back of the stopper continues into an edge which, projecting above the end edge of the tube, merges into an inward pull tab 19.
  • the latter is angled and runs essentially parallel to the slightly curved ceiling of the cap, which ends in the edge areas in a stronger transverse curvature, which is followed by the cylindrical jacket wall of the cap.
  • the function of the dispenser described is as follows: after the cover cap 16 has been removed, the head piece 5 in the region forming the bellows B, which is ruffled on the upper side or roughened in some other way, is pressed downward in the direction of the piston 2. This only creates pressure on the folding valve 9.
  • the pasty mass (not shown) present in the interior R1 pushes through the tube 7 due to the reduction in volume within the head piece in the direction of the outlet opening ⁇ and finally emerges from the outer mouth end 7 '. If the head piece 5 is now relieved, negative pressure is created in the interior R1.
  • the flexible head piece 5 returning to its basic position now pulls the piston 2 in the direction of the arrow x over the filling material column.
  • the resetting is completed before the mass remaining in the tube could reach or leave the inner mouth end 7 "as a plug.
  • the negative pressure causes the valve flap 9 'to fold up in the direction of discharge (arrow z); the head piece 5 sucks over the Passage opening 10 full.
  • the spring-loaded valve flap 9 'returns to its closed position. It is crucial in all of this that the cross-section and length of the tube 7, in coordination with the viscosity of the pasty mass and the flow rate that occurs, form a corresponding resistance which bridges the vacuum that occurs .
