Definitions

  • the invention relates to dispensers according to the preamble of claim 1.
  • a donor of this type is the subject of the unpublished DE Pat. P 36 06 711.3 of the applicant.
  • the actuation button is designed as a bow-like double lever mounted on the outside of the housing tube. This increases the cross-sectional shape of dispensers of the generic type and also requires the composite with the pressure floor which penetrates the housing tube wall.
  • the object of the invention is to assign the actuation button more favorably in terms of both use and assembly, but without reducing the functional reliability of such dispensers.
  • the housing tube no longer needs to be broken.
  • the actuation handle is conveniently located as a button in the head area of the dispenser. It can be easily moved in the axial direction, ie the longitudinal direction of the pipe housing. At the same time, it forms the lid of the space receiving the sack of the dispenser, which not only leads to a pleasing closure of the head area, but also has an effect which favors the dispensing in that the edge of the dispensing opening acts practically as a centering ring pressure surface for pushing through one end of the sack.
  • the edge of the actuating handle strikes the front ends of an insert piece of the housing tube which has the transport toothed strips and the abutment toothed strips.
  • a special connection between the driving and driven part is dispensable.
  • a non-positive connection is sufficient.
  • the front ends of the transport strips form a roof-shaped tilting apex which projects into edge notches of the cap-shaped actuating handle.
  • the dispensing opening is designed as an outwardly drawn spout of the cover.
  • the ruffled end of the bag inserted here nestles under the pressure of the dispensed material against the spout wall.
  • the dispensing opening is centered on the actuating handle which is oval in plan; the top of the operating handle is designed as a continuously increasing elevation on one of the two narrower oval curves. The latter forms the actual actuation pressure area. It can be easily tipped.
  • the invention proposes that the actuating handle in the area of the opposite, narrower oval rounding has a bearing finger reaching into the wall of the housing tube. This way is one of the easiest mounted single-arm lever realized.
  • the insert has at the lower area a plurality of clip lugs which snap into openings in the housing tube, two of which are assigned to those parts and are positively locked there, which have the abutment toothed strips and at least one clip lug which locks with axial displacement play Part is assigned, which carries the transport rack.
  • both parts are formed of the same material and are connected to one another via axially resilient webs. The connection in this respect consequently creates the springs which stress the transport toothed strips in the direction of the basic position.
  • the dispenser which is matched to the dispensing of pasty filling contents, has a housing tube with an oval cross section.
  • the latter includes the bottom a pressure plate 2 that can be inserted from below. This can be moved gradually in the direction of arrow x via an actuating handle 3.
  • the actuating handle 3 which is embedded in the upper end of the cylinder tube 1 and which can be displaced in the axial direction thereof also forms the cover of the housing tube 1.
  • the cover 4 of the pot-shaped actuation button 3 forms a centrally located dispensing opening 5.
  • the latter is designed as an outwardly drawn grommet 5 'of the cover.
  • the dispensing opening 5 is located centrally to the actuating handle 3, which is also oval in plan. As can be seen, the top of the actuating handle 3 forming the ceiling 4 is realized on one of the two narrower oval curves as a continuously increasing elevation 37. At the highest point there is a trough button area 38.
  • the wall sections between the narrower oval curves are only slightly rounded outwards or parallel.
  • the bearing point of the actuating handle 3, which is designed as a toggle button, is located in the area of the narrower oval rounding opposite, in that an outwardly directed bearing finger 39 engages in a bearing recess 40 on the corresponding inside of the housing tube wall.
  • the horizontally oriented bearing finger 39 is rooted in the vicinity of the lower edge of the pot-shaped actuating handle 3.
  • the wall section lying above is supported on the inner wall of the housing tube 1 in a relatively large area. The corresponding position of the bearing finger 39 thus allows a downward tilting movement without hindrance.
  • the actuating handle 3 is formed on a further outwardly directed finger-like projection 41.
  • the latter holds the actuating handle in the basic position with limited stops.
  • the outer surface of the projection 41 has a bevel, so that there is a kind of clip assignment while driving over the upper edge of the housing tube 1.
  • the projection 41 engages under a locking shoulder 42 on the housing tube side, which extends downward into a shaft 43 in the pivoting radius of the actuating handle.
  • the relevant latching assignment is reversible, ie the actuating handle, which also acts as a lid, can be removed again in order to refill the pasty mass accommodated in a sack 9 or to insert a new sack into the dispenser.
  • the bag 9 is made of plastic film and is foldable. It has the shape of a "sausage” tied at both ends. Its cross-section takes into account that of the tubular housing 1. From the so-called “sausage tips", the upper, gathered bag wall end 9 ', as indicated, protrudes like a grommet through the dispensing opening 5, just above which it is separated. The other end of the bag wall 9 ′′, which is kept closed by a seal 10, projects into a recess 11 in the pressure base 2.
  • the pasty mass M is pressed out via the manipulated axial displacement of two diametrically opposed transport toothed strips 12.
  • Their steep tooth flanks 12 'drag the pressure base 2 in the direction of the arrow x during the return stroke.
  • 2 ratchet tongues 13 start from the pressure floor. They are formed by a collar of the pot-shaped pressure base 2. The collar is interrupted in a crenellated manner, so that there are individual radially movable fingers, which engage with their slightly outward-angled ends in a form-fitting manner in the transport toothed strip 12.
  • the flatter flank 12 ′′ of the transport toothed strips 12 is freely overrun by the ratchet tongues 13 in the event of a counter-movement.
  • the assignment of the actuating handle 3 to the displaceable transport toothed strips 12 is such that the edge 3 'of the actuating handle 3 directed towards the pressure floor presses against the free ends 12''' of the transport toothed strips, which are displaced downward against spring loading.
  • Said end faces 12 ′′ ′′ of the transport toothed strips 12 form an upward roof-shaped tilting apex Sch.
  • the latter is, seen in the tilting plane of the operating handle 3, slightly rounded. It is conveniently located in a lever closer to the bearing finger 39 than to the projection 41, so it is shifted somewhat from the longitudinal median plane of the dispenser or the symmetrically positioned toothed racks.
  • the roof-shaped tilting apices Sch protrude into shape-corresponding edge notches 44 of the cap-shaped actuating handle 3.
  • the apex angle is approximately 100 °.
  • the edge notches 44 which are also basically rounded, are preferably kept somewhat larger in their opening angle, so that there is good tilting articulation.
  • the abutment toothed racks 20 which are axially displaceable via the actuating handle 3 are adjacent to abutment toothed racks 20 which are not included in this movement.
  • the latter have the same sawtooth-like structure as the transport toothed strips 12, that is also a steep, i.e. H. Flank 20 'perpendicular to the direction of displacement x of the pressure base 2 and a back that can be run over, which is formed by a fairly flat flank 20 ".
  • the respective flanks are aligned in the circumferential direction, ie the flank 20" is in the basic position at the same height as the flank 20' etc.
  • the transport toothed strips 12 and the likewise axially aligned abutment toothed strips 20 are combined to form an insert 21 which is inserted into the housing tube 1 in a suitable manner.
  • the insert 21 is consequently practically realized as an oval cross-section sleeve, the abutment toothed strips 20 which lie in the smaller oval edges of the housing tube 1 and are correspondingly arched in a cross-sectionally stable manner.
  • the transport toothed strips 12 and the abutment toothed strips 20 are connected to one another only in the bottom region of the dispenser. With regard to this connection, there are material bridges forming horizontal webs 22.
  • the above-mentioned webs 22 are cut free except for a relatively small residual cross-section in the apex of the oval arch.
  • the width of the horizontally circumferential cut-out slots 22 corresponds approximately to the web width measured in the axial direction. This and a corresponding distance y between the adjacent strips 12, 13 enable the transport toothed strips 12 to be shifted downward and counter to spring loading. This stroke corresponds at least to the dimension of one Tooth spacing.
  • the webs 22 also perform the function of return springs, so that after the actuating handle 3 is released, the basic position of the mechanics always occurs again.
  • the corresponding spring force is dimensioned such that the transport toothed strips 12 from the pressed-down position (see dash-dotted entry) drag the pressure floor upwards step by step while overflowing the ratchet tongues 13, that is to say they move back into the starting position.
  • the abutment toothed strips 20 each have a clip nose 46 which latches in a window-shaped opening 45 of the housing tube 1. Its back is chamfered so that the insertion of the insert 21 from the lower end of the housing tube 1 can be carried out comfortably.
  • the other flank of the clip nose on the other hand, is steep and rests on a corresponding counter surface of the opening 45.
  • the clip nose 46 has the required articulation at the level of a pivot point zone 47.
  • the latter also protrude into an opening 45 '.
  • the relevant locking engagement takes place, however, with axial play corresponding to the actuation stroke dimension of the dispenser mechanism.
  • the spring force holds the clip nose 46 'rounded at the ceiling of the opening 45' there, while when the toothed rack 12 is moved downward, its movement is reliably limited by the underside of the clip nose 46 'hitting the bottom of the opening 45'.
  • the axial play is denoted by y '(Fig. 2).
  • the dispenser head area is covered by a protective cap 48.
  • the latter may be assigned by means of a clip connection or, as shown, only frictionally by plugging onto a stepped collar 49 of the tube housing.
  • a force P is exerted on the pushbutton surface 38.
  • the teeth of the transport toothed strips 12 overflow the ratchet tongues 13 of the pressure floor.
  • the latter is now supported on the abutment toothed strips 20.
  • the restoring force of the webs 22 causes the transport toothed strips 12 to be pushed up into their starting position. The latter takes place with the help of the pressure floor 2 according to tooth mesh.
  • the ratchet tongues 13 now overflow the teeth of the abutment toothed strips 20.
  • the pasty mass in the sack 9 is thereby put under pressure.
  • a portioned strand mass emerges via the gathered bag wall end 9 ', which strand is well shaped due to the spout shape of the dispensing opening 5.
  • the lower limit stop for the actuation stroke can also be obtained by hitting the edge 3 'of the actuation handle 3 on the end face of the stationary abutment toothed strips 20.
  • the housing tube 1 merges into a widened stand edge 33 which favors its positioning security.
