Definitions

  • the invention relates to a dispenser for dispensing pasty masses, such as toothpaste, with an outer housing with an open top and a closed bottom, in the latter an air inlet valve opening at negative pressure in the outer housing is arranged, further one from the outer housing upwardly projecting inner housing is provided, which has an actuating surface and a mouthpiece opening on its head piece, via which actuating surface the inner housing can be pressed against spring pressure into the outer housing sealed against it, so that under this actuation a transport piston migrating in the inner housing in the direction of the mouthpiece opening due to an overpressure of the same built up on the back, the mass pushes in front of it.
  • a dispenser for dispensing pasty masses such as toothpaste
  • a dispenser of this type is known from DE-PS 421 447.
  • the transport piston is moved according to an overpressure built up on the rear of the transport piston when actuated and there generated in a zone on the back of the same.
  • the inner housing designed as a cup, for example containing mustard, has a centrally located hole.
  • a sleeve as a counter-piston under the bottom of the cup.
  • the subject of DE-PS 30 44 439 is a dispenser with an outer housing and inner housing guided therein.
  • the upper end of the cantilevered inner housing forms a mouthpiece opening with an adjacent actuating surface.
  • the inner housing is supported on the bottom of the dispenser by means of a compression spring.
  • the dispenser carries a so-called climbing pole, on which a transport piston is supported by a one-way locking mechanism.
  • FR-A-2 510 071 there is the proposal on a generic dispenser to generate the air pressure at the headpiece of the dispenser having a mouthpiece opening and an actuating surface.
  • the head piece has a dome-shaped, resilient membrane, which can be pressed into a recess in the head piece while reducing the volume of its interior.
  • the compressed air generated in this way is routed behind the transport piston via a central pipeline, which also acts as a guide for a transport piston. It emerges via a transverse channel in the base area, driving the transport piston in the direction of the mouthpiece opening.
  • a dispenser is known, around the centrally suspended receiving chamber of which a squeeze body is arranged, the jacket wall of which can be compressed into a flatter shape so as to drive a transport piston in the direction of the mouthpiece opening of the dispenser.
  • the air overpressure generated in the vicinity of the tubular receiving chamber over almost the entire length of the dispenser is connected to the latter via the end of the receiving chamber which is open at the bottom.
  • the invention has set itself the task of structurally simpler construction of a generic type and still functionally reliable.
  • the inner housing be designed as a sleeve open to the bottom of the outer housing, the bottom of the outer housing can be removed and the seal of the inner housing by means of a seal with the bottom of the outer housing firmly connected, protruding into the inner housing.
  • the feed takes place via an "airlift” and no longer via a vacuum situation interspersed with mass.
  • the air overpressure is built up by approaching the rear side of the transport piston to the counter-piston fixed to the housing, the space between the two pistons being connectable to the outside air, that is to say the atmosphere, by means of a valve which opens when the distance between the pistons increases.
  • the valve immediately allows air equalization to occur when the appropriate distance is increased, ie the volume previously given is added to air.
  • the compressibility of the enclosed air also leads to a welcome increase and deceleration of the mass output. It is not thrown out in an uncontrolled manner.
  • the invention further proposes that the counter-piston sits on a base of an outer housing, relative to which an inner housing can be displaced against spring loading in such a way that the base moves into the lower end of the inner housing which projects with its actuating surface above the upper edge of the outer housing.
  • the inner housing is usefully used to expand the functionality by forming the head piece, containing the mouthpiece opening and the actuating surface.
  • a compression spring is arranged between the lower edge of the inner housing and the bottom of the outer housing. This automatically results in the starting position for the next delivery stroke.
  • the base and base of the outer housing can be screwed onto the lower end of the housing jacket wall.
  • This not only has a fundamental advantage with regard to the formation of a gate that enables the insertion of the inner housing, but also that of the gentle screwing in of the counter-piston. His lips cannot turn over, as could be the case, for example, with a purely linear feed and not yet overlapping rotary movement.
  • the screwing on forms, moreover, a type of coordination familiar to the consumer, so that the donor is accepted for this reason as well.
  • the relevant spring abutment is designed in such a way that the end of the compression spring on the inner housing side is covered by an annular guide piece.
  • the latter can be used at least for the partial formation of a spring chamber in that the cross section of the guide piece is U-shaped and the lower edge of the inner housing rests on the U-web. It also proves to be advantageous that the lower edge of the inner housing is pressed by the compression spring against a stop of the outer housing. This results in a basic position that always recurs.
  • the stop continues in longitudinal guide ribs for the inner housing; in other words: the longitudinal ribs end on a common transverse plane of the dispenser to form the stop.
  • valve closure body of the valve is connected to the piston ring via webs.
  • the valve and piston ring are one structural unit.
  • a design of even independent importance results on a cartridge-shaped inner housing for use in a dispenser according to claim 1, in that a wall section protruding above the transport piston forms the cylinder space for a counter-piston which can be inserted there from the lower end.
  • the inner housing can be implemented in the form of a refill pack, so that such a dispenser can be used again and again.
  • Andokken is optimized by a funnel-shaped counter-piston inlet section at the lower edge of the sleeve-shaped housing wall.
  • the inner housing is designed as a sleeve open to the bottom of the outer housing, the bottom of the outer housing is removable and that the seal of the inner housing by an open End of the sleeve wall of the inner housing with the bottom of the outer housing connecting bellows.
  • the bellows can be molded in one piece onto the lower edge of the inner housing by using the restoring force of this material.
  • a solution is advantageous in that the bellows is created as a separate component. It has proven to be advantageous for the air inlet valve to sit on a base overflowed by the inner housing, which base forms a holding projection for the upper edge of the separately designed bellows.
  • the bellows can already be assigned to the base with a certain preload. It is also favorable that the base is formed from the bottom of a screw cap, on which bottom the lower edge of the bellows is supported. Finally it turns out as advantageous that the bellows is designed as a bellows and is the return spring of the inner housing.
  • the dispenser Sp shown is realized as a standing device. It has a long cylindrical outer housing 1. This accommodates an inner housing 2 which is axially longitudinally guided therein.
  • the inner housing 2 is a sleeve-shaped structure which contains pasty mass 3 to be dispensed.
  • the sleeve-shaped inner housing 2 has a cup-shaped shape, so it is open at one end. The opening-side end points downwards.
  • the other, closed end of the inner housing 2 forms a lateral mouthpiece opening 4 with a molded-on tamper-evident closure 5.
  • the tamper-evident closure 5 tapers and, after breaking off by reversing insertion into the mouthpiece opening 4, can possibly function as a sealing plug.
  • An actuating surface 6 is located to the side of the mouthpiece opening 4.
  • the latter is part of a head piece 7, formed by the end of the inner housing 2 that projects freely above the outer housing 1.
  • the direction of actuation is indicated by arrow P in FIG.
  • the dispensing mechanism M effects a gradual displacement of a transport piston 8. This pushes with its front 9 the pasty mass 3 in the dispensing direction, that is, in the direction of the mouthpiece opening 4. This direction is indicated by arrow x.
  • the displacement of the transport piston 8 takes place via air pressure loading, specifically as a result of an air overpressure built up on the back of the transport piston 8 when actuated.
  • the pressure-loaded rear side of the transport piston bears the reference number 10.
  • the zone of the excess air pressure generated is designated by D.
  • the excess air pressure is built up by bringing said rear side 10 of the transport piston 8 closer to a stationary, i.e. counter-piston fixed to the housing 11.
  • the latter protrudes sealingly into the end of the inner housing 2 there of the transport piston 8 downwardly projecting wall section 2 'of the housing wall of the inner housing 2 remains.
  • This wall section thus creates a cylinder space 12 for the counter-piston 11 of the dispenser mechanism M of the dispenser Sp which can be retracted from the lower end in the case of assembly or subsequent assembly.
  • a valve V is assigned to the counter-piston 11. Via this there is a connection between the space 12 or cylinder space 12 and the atmosphere.
  • the valve V opens when the distance between the transport piston 8 and the counter-piston 11 is increased. Via this path, which is open to the outside air or atmosphere, the space 12 is increased by the volume of the mass 3 dispensed balanced by air.
  • the valve V acts like a check valve.
  • the counter-piston 11 forms the upper end of a base 13, which starts directly or indirectly from the outer housing 1.
  • the base 13 is an integral part of a base 14 of the dispenser Sp.
  • the base 13 / base 14 unit is screwed to the lower end of the casing wall 15 of the dispenser Sp.
  • the bottom 14 continues peripherally in a raised ring wall 16.
  • the latter forms a cap and carries an internal thread, which interacts with a corresponding external thread on the housing jacket wall 15.
  • the annular wall 16 is overlaid on the upper side by a circumferential covering bead 17.
  • the latter is also integrally formed on the housing jacket wall 15 of the outer housing 1.
  • annular collar 18 that extends concentrically to the annular wall 16 and extends inside the wall of the outer housing 1.
  • the latter has a greater axial length than the peripheral annular wall 16, and exceeds its length by about half to double measure.
  • the base 13 is designed as a recess which extends radially at a distance from the ring collar 18 and which ends with a horizontal cover 19 on the mouth opening side.
  • the cover 19 is framed peripherally by a piston ring, forming the counter-piston 11 mentioned.
  • the flexible or elastic piston ring engages with an inside clip bead 20 in an adapted annular groove 21 below the plane of the cover 19.
  • the cover 19 and piston ring thus form the counter-piston 11 In the basic position, only the opposing piston 11 projects, ie the upper end of the retraction, into the cylinder space 12 formed by the wall section 2 '.
  • the flexible material of the piston ring opens up a further development in that it forms the valve closure body 22 of the valve V.
  • the latter has semi-spherical or conical shape and is directed downwards. Its surface cooperates with a valve seat surface 23.
  • This valve seat surface 23 is realized by the upper edge of an air passage opening 24 in the ceiling 19 of the base 13.
  • the downward opening of the base 13 functions as an air duct.
  • the centrally located valve closure member is connected to the ring piston via webs 25.
  • the webs are designed as curved, horizontally aligned radial webs. They have an S-shaped course. A total of three webs 25 arranged at equal angles are realized.
  • the inner ends engage on a node plate 26 carrying the valve closure body 22, in which the valve closure body 23 is rooted centrally.
  • Said retraction has a cylindrical shape and its outer diameter clearly decreases compared to the inside diameter of the inner housing 2.
  • the described piston ring of the counter-piston 11 projects into the intermediate space.
  • the inner housing 2 is in the direction of its stop-limited basic position shown in FIG. 1 under spring loading.
  • a compression spring 27 used in the area of the dispenser mechanism M is used for this purpose. It is a helical compression spring. It holds the dispenser head in such a sufficient board position that its head piece 7 protrudes far beyond the upper, retracted edge 28 of the outer housing 1. The retracted position results from FIG. 3.
  • the compression spring 27 extends between the lower edge 29 of the inner housing 2 and the bottom 14 of the outer housing 1.
  • the cylindrical helical plane of the compression spring 27 is practically aligned with the cylindrical, elongated wall plane of the inner housing 2.
  • the upper end turn of the compression spring 27 does not occur immediately against the lower edge 29 of the inner housing; the inner housing end of the compression spring 27 is rather covered by an annular guide piece 30.
  • This has a U-shaped cross section.
  • the U-opening points in the direction of the bottom 14.
  • the U-shaped guide piece is of such a length that it is also in the Figure 1 apparent basic position at least with its outer U-leg does not leave an overlapping projection to the ring collar 18 of the bottom 14. Said leg leads on the inner wall of this ring collar, while the other U-leg finds its guidance on the outer surface of the cylindrical, downwardly open retraction of the base 13. In this way, a spring chamber 31 is created for the compression spring 27.
  • the lower edge 29 of the wall section 2 ′ or of the inner housing 2 is supported on the upper side of the horizontal U-web 32 of the guide piece 30.
  • the protruding position of the head piece 7, which defines the basic position, is stop-limited. This is done in such a way that the lower edge 29 of the inner housing 2 is pressed by the compression spring 27 against a stop 33 of the outer housing 1. With regard to this stop 33, there are the downward-facing, beveled ends of a plurality of guide ribs 34 on the inside of the cylindrical inner housing 2.
  • the strip-like longitudinal guide ribs are particularly clear from FIG. 4 and provide only a small guide surface between the leading outer housing 1 of the dispenser Sp and the guided inner housing 2 of the same. The aforementioned slope of the front ends converges in the direction of delivery (arrow x).
  • the funnel has such an inlet width that the usually existing, projecting sealing lips 36 of the two pistons, 8, 11 can be gently constricted against their resilience without the risk of a change. That brings density.
  • the head piece 7 can be covered with a protective cap 37 when not in use.
  • the latter is in plug or screw connection with the outer housing 1.
  • the base 14 is unscrewed and a new refill cartridge is inserted. This is conveniently done with the dispenser head pointing downwards.
  • the counter-piston 11 arrives in the region of the wall section 2 'by means of the docking assignment. It closes the cylinder chamber 12.
  • the dispenser Sp according to the second exemplary embodiment has an identical structure as far as the basic principle of the positive air pressure driving the transport piston 8 is concerned.
  • the reference numerals are used analogously, in part without repetitions of text, and the text is therefore also largely readable for the second exemplary embodiment.
  • a bellows B now occurs instead of the counter-piston 11 fixed to the housing. It is a bellows which can be compressed in the direction of the arrow P and which adjoins the lower edge 29 of the inner housing 2.
  • the bellows can be made in one piece with the sleeve-shaped structure of the inner housing 2, which forms a refill cartridge, in that its jacket wall, ie wall section 2 ', continues downward over the lower edge 29 in the direction of the base 14.
  • the lower edge 38 of the bellows B is sealed against the corresponding top of the bottom 14.
  • the sealing effect can be generated from the elasticity of the bellows-forming material. This can be done using the internal pressure, it being advantageous for the end fold 39 of the bellows there to be pressed against said upper side.
  • the terminal fold 39 can, as shown, be made wider, using an even larger area and a larger area for the effective internal pressure.
  • the inner end edge of this fold 39 ends in front of the base 13, which is also present in this embodiment, of the bottom which has been turned up to a cap 14.
  • the cap is also implemented here as a screw cap 40.
  • the bottom seal is marked with a.
  • a corresponding seal is also present between the lower edge 29 of the wall section 2 'of the inner housing 2 and the bellows B adjoining at the bottom.
  • This seal bears the reference symbol b. It is located between the flat underside of the lower edge 29 and the corresponding upper edge 41 of the bellows B. This upper edge 41 is a horizontal step. Following this horizontal step, the bellows B merges into a plug-in projection 42 with which it projects into the lower, open end of the respective refill cartridge.
  • the outer wall of the plug-in projection 42 is cylindrical. It lies sealingly against the corresponding cylindrical inner surface of zone D which generates the excess air pressure.
  • the projection 42 is concentric around the central base 13 and is tapered in the direction of the cylindrical jacket wall of this base 13, while maintaining a continuous wall thickness.
  • the horizontal ring web 43 thus obtained is used to secure the bellows B plugged onto the base 13.
  • the involvement of this fuse on the socle side is such that a holding projection 44 lies above the top ceiling 19 of the base 13 on the jacket wall side.
  • It is molded onto the base and realized as a circumferential ring rib, the outward-facing end edge of which converges rotationally symmetrically upwards, so that the ring web 43 can be pulled open easily.
  • the upper side of the ring web 43 comes into contact with the flat lower side of the holding projection 44.
  • the bellows can have the corresponding preload. It is held captive at 13.
  • valve V in the area of the horizontal ceiling 19.
  • This is also an inlet valve, which is now simply a plug-in type formed rubber or plastic tab is formed, which overlaps the centrally located air passage opening 24 in the ceiling 19.
  • the ceiling occupies a lower position, ie the wall of the base 13 extends significantly beyond the top of the ceiling 19.
  • a collar 46 circumscribing a pot cavity 45 is created.
  • the opening of the pot cavity 45 is closed by a clip-on cap 47. It is centrally perforated.
  • the corresponding holes have the reference symbol 48.
  • the cap 47 protects the valve body and secures it against falling out.
  • An annular gap 49 remains between the inside of the ring web 43 and the outer wall of the base 13. This connects the zone D to the annular interior 50 of the bellows B.
  • the screw cap 40 lies outside the bellows receiving space with the top of the base 14 against the corresponding end face 51 of the outer housing 1. This creates a seal c or better screw limitation.
  • the base 13 has an opening lying in the direction of the base of the dispenser Sp.
  • the dispenser Sp When the dispenser Sp is equipped, a force is exerted on the head piece 7 in the direction of the arrow P in order to dispense its contents in portions.
  • the base 13 overflows through the inner housing 2, but now not in the sense of a relative displacement between the cylinder and a counter-piston, but in the sense of a volume reduction in the zone D of the dispenser which builds up the excess air pressure. This can be done by running through the entire available stroke or by going through a partial stroke of the same.
  • a maximum compression is shown in FIG. 6 in that the folds of the bellows B lie on one another in an ossified manner. The volume of zone D is reduced there. The portion in the bellows can breathe through the annular gap 49.
  • the compressed, enclosed air exerts pressure on the rear side 10 of the transport piston 8.
  • the latter pushes mass 3 from the mouthpiece opening 4 strand-shaped.
  • the actuation takes place against the restoring force of the bellows, which acts as a compression spring and is sealed off from the outside.
  • a certain slight sagging movement of the pasty mass 3 and the transport piston 8 has an advantageous side effect in that they suck in a protruding residual protruding mass of the strand via the mouthpiece opening 4. Otherwise, the air cushion is secured by the valve V to prevent the air from escaping, because the axial distance which decreases between the rear 10 and the top of the base 14 creates such a high air cushion that the flap valve closes tightly against the valve seat surface formed by the edge of the air passage opening 24 is pressed.
  • the air equalization is effected to the extent of the mass volume delivered. Having returned to its stop-limited basic position, the inner housing 2 can be used for the next delivery stroke, etc.
  • the base 14 forming part of the screw cap 40 is unscrewed and a new refill cartridge is inserted. This is conveniently done with the dispenser head pointing downwards.
  • the bellows B By inserting or unscrewing the screw cap 40, the bellows B, when formed separately, is docked to the cartridge or to the wall section 2 '.
  • Zone D is hermetically sealed. A pre-compression in zone D which already occurs when the projection 42 occurs contributes to the formation of a pressure cushion supply. The dispenser is ready to use.
