Definitions

  • the invention relates to a metering pump that can be placed in particular on bottles or the like, according to the preamble of the main claim.
  • the object of the invention is to provide a generic metering pump with a simple construction and assembly technology that is stable in use, so that the guiding stability is obtained from components of the metering pump that are present anyway.
  • a generic pump which is characterized by a simple, stable construction.
  • the relatively thin-walled pump bellows is simply inserted freely between two components of the pump housing that are in contact with one another. There is no tilting of the pump bellows and a corresponding displacement of the mouthpiece which affects the accuracy of the output more.
  • the pump bellows itself forms the return spring. Specifically, the procedure is such that the mouthpiece-side valve closure body sits in the ceiling of a cap that overlaps the pump bellows, the side wall of which leads to the wall of a pot surrounding the pump bellows, in the bottom of which the inflow-side valve closure body sits.
  • the inner surface of the side wall leads on the wall formed by the outer surface of the pot. It also proves to be advantageous in terms of allocation that a screw-on part of the metering pump attaches to the underside of the base and that a riser pipe connection tube with a valve closure body arranged in it is centrally located. The screw-on part also provides an extended guide surface for the axially displaceable cap.
  • the foot support ring on the pot base fulfills a further function in that it covers an air inlet opening of the pot base in the manner of a sealing lip and, for this purpose, rests on the inner wall of the pot with a free-standing lip section.
  • the lip section acts like a valve, which is why an acute-angled contact is made.
  • At least the mouthpiece-side valve closure body has horn-like protruding spring tongues which are supported on the underside of an actuating surface of the cap, which actuating surface overlaps the ceiling of the cap with an axial distance. It can be a plug-in part, which is held by means of the clip connection.
  • the procedure is such that retaining lugs for capturing this valve closure body are assigned to the upper edge of the connecting tube hole receiving the bottom valve closure body. In this way, the relocation of the Valve closure body limited in its open position.
  • the invention also proposes that the pump bellows be designed as a threaded bellows. This can therefore be created as a precision part, as is not possible, for example, in the blowing process. There is also no need to work with a disintegrating mandrel; rather, the mandrel can simply be unscrewed. Effective locking can also be achieved with structurally simple means by rotating the two pump parts relative to one another. So accidental touches can not lead to a spreading of the filling contents. Prior to this, the willful, pump-oriented alignment of the pot and cap is required.
  • the outer surface of the pot has grooves and ribs on the entire circumference in an even distribution, only a fraction of which in the longitudinal direction upwards is open, namely those that are in one rotational stop position in front of the ribs of the cap.
  • the rotational stop position is formed by lugs of the pot which abut against the side flanks of the ribs of the cap. In this respect, these ribs even have an additional function; they form the counter-stop for the noses, which can be taken into account when spraying the pot.
  • the procedure is simple in that the cap can be rotated into a collar of the pump bellows with a central connecting piece which accommodates the valve body intervenes.
  • an advantageous embodiment is realized by several pairs of ribs provided in an angularly symmetrical arrangement on the inner surface of the cap. The impact load is distributed over a corresponding number of surfaces. This has the advantage that the rib height is very low can be worked.
  • the cap leads on the inner wall of the pot, the side wall continues in fingers, which penetrate slots under the bottom and reach under it, and in the pump movement in drive in a space formed between the wall of the pot and the bottle neck, below which free space the pot is attached to the bottle neck.
  • the anchoring-like composite zone of the pump parts thus extends outside the bottle neck and is easily reached through fingers of the cap that pass through slots in the bottom.
  • the latter have, according to the guided assignment of the cap on the inner wall of the pot, a correspondingly precise alignment, so that there is always an exact grip on the bottom.
  • the fingers When stepped into the anchoring position, the fingers secure the pump assembly containing the equipment, such as the bellows, the valve body, etc., of which the bellows, which also acts as a spring body, presses the cap back into the pump-ready position.
  • the space for the fingers during pumping movement is between the wall of the pot and the bottle neck in the most economical way.
  • the fastening point between the bottle neck and the pot of the dosing pump At the lower end of the free space is the fastening point between the bottle neck and the pot of the dosing pump.
  • the free space is advantageously designed by narrowing the cross section of the bottle neck towards its upper end. The pot can thus continue downwards beyond its section forming the guide, so that there is a constant gripping area for the holding hand.
  • the radially outwardly resilient fingers engage under the floor with radially inwardly directed locking lugs.
  • the escape space for the fingers which spring out correspondingly during assembly is achieved simply by displacing these fingers radially inwards relative to the guided outer wall of the cap or by removing the back of the fingers.
  • the locking can be reversible or irreversible. An irreversible installation would be preferred for disposable pumps. Instead of directly engaging behind the locking lugs, the fingers can one Reach in between the sealing ring lying between the bottom and the end of the bottle neck.
  • the procedure is further advantageously such that a radially outward-pointing, beak-like mouthpiece of the cap rotatable to the pot lies in the pump-ready position above an entry niche in the pot wall. If the mouthpiece is not in congruent alignment with the entry niche mentioned, the cap cannot be axially displaced in the sense of the execution of the pumping movement.
  • the procedure is then simply that a locking projection from the lower edge of the side wall of the cap which can be rotated to the pot goes in the same direction with the fingers, which is in the pump-ready position above an opening in the floor and in its locking position hits the floor.
  • the locking projection is formed by a widening in the attachment area of the finger and the opening by a partial section of the slot.
  • the metering pump 1 is screwed onto the neck 2 of a bottle 3. Their external thread bears the reference number 4. The internal thread which can be brought into engagement with this is designated by 5.
  • the metering pump is fastened by clipping.
  • the neck 2 has an annular groove 2 '.
  • An annular rib 41 of the pump body engages in this.
  • the annular groove 2 ' is preceded by a run-up slope 42 formed by a frusto-conical wall section of the neck 2.
  • the screw-on or top part 6 of the metering pump 1 starts below the horizontal bottom 7 of a pot 8. The latter points upwards with its opening.
  • the latter is overlaid on the top by a cap 9 which, according to the first exemplary embodiment, runs on the pot 8.
  • the upper end of the pump bellows B is supported on the ceiling 10 of the pot 8.
  • the end edge 8 'of the pot 8 extends at a distance x to the underside of the ceiling 10, which in the pressure actuation position (see FIG. 2) indirectly the stroke limit stop for the in the direction of the base of the bottle forms cap 9 displaceable against spring action.
  • Their inner surface 9 ' runs on the wall 8 "formed by the outer surface of the pot 8.
  • the return spring is formed by the pump bellows B itself.
  • the basic position of the dosing pump is stop-defined.
  • the cap 9 forms an inwardly directed annular collar 11 at its lower edge.
  • the latter snaps behind a pot-side shoulder 12 at the level of the bottom 7 of the pot 8.
  • the lower section of the pot forming the screw-on part 6 jumps back slightly in cross-section.
  • Its cylindrical outer surface has an axial length which corresponds at least to that of the distance x, so that the outer surface is available as an additional guide surface for the cap 9.
  • the cap 9 runs in the pot 8.
  • the end edge 9 "of the cap 9 extends at a distance x from the top of the base 7. This distance corresponds to the actuation stroke, so that the limitation results therefrom results for the cap 9 which can be displaced in the direction of the standing surface of the bottle against spring action.
  • the outer surface 9 'of this leads on the inner surface 8 "' of the pot 8.
  • the return spring is formed by the pump bellows B itself.
  • the basic position of the metering pump 1 which also forms the pump ready position is also stroke-defined. For this purpose, fingers FG start from the cylindrical side wall of the cap 9 guided in the pot 8.
  • the latter originate from the end edge 9 ′′ of the cap 9 and continue in the direction of extension of the side wall of the cap 9, namely in the direction of the standing surface of the bottle or in the direction of the base 7 which they penetrate.
  • the base 7 has slots 43, the The rest, inner edge of the fingers FG in the basic position is attacked directly or indirectly
  • the restoring force of the bellows B holds the fingers FG in the form of locking lugs 44 which are formed radially inward, so that the fingers FG or their locking lugs 44 have free ends when the lock is passed outward-facing inner flank of the slots 43 can overrun with sufficient clearance, the slots 43 have a radial width corresponding to the locking head, ie they jump back by the amount of the projection of the nose relative to the inner wall of the cylindrical pot 8.
  • the nose bridge of each finger FG has a run-up slope 45 on, so that the locking lugs 44 easier during assembly from their axial extent kungslage can be pushed out, then underpinning the corresponding slot edge.
  • a sealing ring 47 is interposed between the underside of the base 7 and the bottle neck end edge 46.
  • the latter has a triangular cross section.
  • the longer side of the triangle forms a flat, conical sealing flank, which, however, adjoins the cylindrical, cross-sectionally tapered portion that adjoins the run-up slope 42 Exceeds section to the outside, so that the required possibility of reaching under the locking lugs 44 is given.
  • the front edge 46 converges upwards on both sides.
  • the upper region of the bottle neck 2 close to the end edge is thinner than the lower region.
  • the latter together with the inwardly curved edge part forming the annular groove 2 ', stiffening the entire neck section.
  • the detents 44 When the pump is actuated, which is done by pressing the cap 9 downward, the detents 44 lift off from the bottom or the sealing ring 47 on the underside; they deflect into an annular free space 49 formed between the pot wall in the area of the top part 6 and the bottle neck 2 and concentric about the longitudinal central axis y-y of the pump body 1. Its axial length is dimensioned so that the fingers FG can retract freely.
  • the attachment point between the bottle neck 2 and the pot 8 extends at a sufficient distance below the required actuation stroke.
  • the free space 49 is formed by the aforementioned cross-sectional tapering of the bottle neck 2 in the region of its upper end.
  • the bottom 7 forms a connecting tube 13 arranged centrally for fitting a riser tube 14.
  • the latter extends to just before the bottom of the bottle 3, so it is immersed over its entire length in the liquid medium 15 to be dispensed.
  • the connecting tube 13 has a diameter which still leaves a sufficient annular space between its jacket wall, which is slightly offset in the central region, and the bottle opening 16, into which the connecting tube 13 thus projects freely.
  • the upper, somewhat widened half of the connecting tube 13 contains an axially guided valve closure body 17, the top of which lying, flat, frustoconical plate 17 'comes in the closed position against a valve seat 18 of the passage hole in the bottom 7. Following the tightly fitting plate rim, the flat, frustoconical section of the plate 17' jumps back from the inner tube of the connecting tube and sits in a cross-profiled valve closure body. Leadership 19 continued.
  • retaining lugs 20 extend from the upper edge of the connecting tube hole receiving the bottom valve closure body 17 for capturing the valve closure body 17, which is thus axially displaceable to a limited extent.
  • the holding lugs 20 are molded onto the base 7 in the same way. In general, two holding lugs 20 arranged diametrically opposite one another are sufficient. However, three holding lugs 20 which are arranged in the same angular distribution to one another are expediently preferred.
  • the vertical nasal passages deviate from 17 when the clips are assigned.
  • the second of the two valve closure bodies 21 arranged in the region of the ends of the pump bellows B is located in the cover 10 of the cap 9.
  • the latter is of the same construction as the valve closure body 17, which is why the reference numbers are transferred analogously, without text repetition. The only difference is that it is not held in its closed position depending on the weight, but is under spring load in this direction.
  • two spring tongues 22 extend from the top of the plate.
  • the latter are horn-like in shape, ie they diverge and end in an outward curve. These rounded end sections come against the underside 23 'of an actuating surface 23 of the cap 9.
  • the actuating surface 23 which is indented from the top according to FIG. 2 extends axially from the ceiling 10 of the cap 9.
  • the actuating surface 23 is formed by the bottom part of a pot-shaped plug-in part 24, which is clipped like a lid into an extension 25 of the cap 9.
  • the clip zone carries that Reference numeral 24 '.
  • An irreversible clip assignment is preferably used.
  • the collar-like, correspondingly upwardly open extension 25 of the cap 9 forms, together with the plug-in part 24, directed radially outward, a beak-like mouthpiece 26, the channel 27 of which is fluidly connected to a chamber 28 realized in the region of the extension 25.

  • the latter has an axial length such that in the pump actuation position it remains at a sufficient distance from the retaining lugs 20 (see FIG. 2). .
  • the end folds 30 of the pump bellows B each sit on a collar 31 of the base 7 or the cover 10 (FIG. 10). Both collars 31 extend concentrically to the longitudinal center axis yy of the metering pump. The end folds 30 of both ends then continue in foot support rings 32.
  • the foot support ring 32 On the pot bottom side, the foot support ring 32 has a further function. This extends over one or more air inlet openings 35 in the bottom 7 of the pot 8. It has a sealing lip function and, with its free-standing lip section 32 ', rests elastically on the corresponding inner wall 8111 of the pot.
  • the circumferential lip portion 32 In order to replace the volume of air corresponding to the volume dispensed, the circumferential lip portion 32 'lifts off from the inner wall of the pot 8''' during the suction stroke of the pump bellows, so that air in via the joint F between the pot 8 and the cap 9 in the direction of the arrow z can enter the bottle interior. In the basic position, however, the lip section 32 'returns to its sealing position shown in FIG. 1. Since said lip section 32 'runs in an obliquely sloping orientation and when the pump bellows is compressed, a tilting moment arises in the direction of the inner wall 8''of the fold end point, the corresponding sealing system is also mechanically favored, especially since Pump bellows is also used with a slight preload.
  • Such a valve function of the lip section 32 'prevents medium 15 from escaping or falling into the free, annular space-like environment of the pump bellows if the bottle has fallen over.
  • the lower edge of the end fold 30 there of the pump bellows B lifts off from the air inlet opening 35 on the upper side.

  • the rotary stops for both end positions are formed by lugs 36. The latter, as can be clearly seen in FIGS. 5-9, extend from the upper end edge 8 'of the pot 8.
  • the pairs of ribs extend in an angularly symmetrical arrangement on the inner surface 9 'of the cap 9.
  • the angular distance is 120 °.
  • the corresponding multiplication of the stops brings the advantage of a low rib height, since the stop pressure is distributed over several surfaces. Pot and cap can therefore be kept very thin-walled.
