Definitions

  • the invention relates to a valve-free dispenser for pasty masses, for. B. toothpaste, with slidably arranged in the dispenser housing below the mass, migrating in the dispenser emptying in the direction of the mouthpiece opening, blocked in the opposite direction by a ram, and a push button actuating surface for displacing an upper pressure blanket provided in the dispenser housing above the mass, which with the piston is coupled via a rod passing through it, which is non-positively coupled to the piston with the interposition of a second locking mechanism working counter to the first locking mechanism.
  • a favorable embodiment consists in that the button is linearly guided in a cup-shaped recess in the housing cover and over a pin is connected to the pressure cover designed as a piston, the cylinder space of which is formed by a projecting collar of the housing cover, which extends at a radial distance from the inner wall of the housing. The latter provides a piston guide that is free of holding forces and therefore runs smoothly.
  • the linear guidance of the piston can also be used for guidance, the collar forming its cylinder space bringing a considerable additional stabilizing moment, so that a surprisingly small wall thickness can be assumed.
  • the connection of the components forming the dispenser mechanism is solved in the simplest way by a latching between the push button and a connecting piece of the housing cover, which starts from the cup-shaped recess.
  • the pressure blanket continues in the central area into the tubular guide piece, the tube cavity of which leads to the mouthpiece discharge channel.
  • the guide piece takes on an additional task by being involved in the channel formation.
  • the printing blanket can be molded in the same way.
  • An advantageous development in this regard is that the widened end connection area of the rod forms the passage cross sections for the tube hollow of the guide piece. Such passage cross-sections are located directly in the area of the printing blanket, so that the dispenser can be emptied completely.
  • the push button be designed as a one-armed lever engaging the guide piece in the central region. The actuation forces are transmitted in the most favorable manner, the entire cross-sectional width of the dispenser housing, ie its head region, being available for the lever bearing.
  • this clamping module 3 forms a second locking mechanism G 2.
  • a rod 4 which penetrates the piston 2 centrally, interacts with the latter.
  • the correspondingly inwardly directed tines 3 "engage the rod 4 formed by a smooth rod. Projected into the plane, the passage opening of the clamping module left by the tines 3" is smaller than the diameter of the rod 4.
  • the end of the rod 4 facing the standing surface St of the upright dispenser is rounded or, as can be seen from FIG. 6 (third exemplary embodiment), tapered.
  • the rod 4 extends axially into a guide piece F extending beyond the pressure blanket 8.
  • the latter passes through a guide opening 10.
  • the latter is located in a housing cover 11 that overlaps the pressure cover 8.
  • the connection of the pushbutton 7 with the pressure cover 8 takes place above the housing cover 11 mentioned, using suitable clip or clamping means.
  • the bottom 12 'of the recess 12 acts as a limit stop for the pushbutton 7 by placing its pot edge on it.
  • Pushbutton 7 plus printing blanket 8 are furthermore in a latching connection to a connecting piece 17 which forms the guide opening and which extends centrally from the bottom 12 'of the depression 12 in the direction of the pushbutton 7.
  • This nozzle 17 is the housing. ke 11 molded at the same time.
  • the locking connection bring diametrically opposite lugs 18, which run axially in longitudinal slots 19 of the nozzle 17.
  • the steeper flank of the lugs 18 strikes the upper edge of the longitudinal slots 19.
  • the length of the longitudinal slots 19 takes into account the dimension required for the working stroke.
  • the back of the lugs 18 is shaped into a run-up slope. This facilitates the establishment of the plug-snap connection.
  • the pressure blanket 8 designed as a piston runs in a cylinder space 20 which is open to the interior of the housing over the entire cross-sectional width.
  • the cylinder space 20 is formed by a collar 21, the inner edge of which is chamfered, which is formed on the underside of the housing and is free-standing, this for easier insertion of the piston body, which corresponds to the construction of the piston 2 in terms of lip design.
  • the recess 12 formed by a recess protrudes into the piston space to save space.
  • Collar 21 and recess wall have the corresponding radial clearance, so that an annular groove 21 results.
  • the collar 21 leaves a radial distance from the housing inner wall 1 'concentrically surrounding it.
  • connection between the rod 4 and the pin 13 of the pressure blanket 8 takes place via a mushroom head 22 which is clipped into a locking cavity 23 at the end of the pin 13 facing the mass M.
  • the stop providing the free movement z is realized between a collar 27 lying below the locking point and the section of the guide piece F forming the locking cavity 23.
  • the reference numbers are applied accordingly.
  • the end connection area between the rod 4 and the guide piece F is also reached by means of the latching connection.
  • the end of the rod 4 facing the printing blanket 8 forms a basket 30 into which a nozzle 31 extending from the underside of the printing blanket projects.
  • the latter forms a locking ring 32 or individual locking lugs on its outer surface.
  • the latter engage in an annular groove 33 adjoining the basket edge.
  • the axial height of the annular groove again takes into account the above-mentioned clearance z.
  • the actual, openwork section of the basket only begins below the annular groove 33.
  • This basket section is formed by axially directed webs 34, which connect the section forming the end connection area to the rod 4. Between the webs 34, which are bent inwards at half the length and are rooted in the head region of the rod 4, flow cross-sections 35 leave free, so that the mass M, passing through it, passes through the nozzle 31 and via the tube cavity H of the guide piece F into the Output channel 26 arrives.
  • the webs 28 are kept quite flat, so that on both sides of these webs segment-shaped cross-sections 35 remain.
  • the latching connection between the web section and the tubular guide piece F lies essentially within the zone surrounded by the connecting piece 17, which gives the portion of the guide piece F having the depressions 29 a good radial support.
  • the tubular section can be slightly flattened transversely to the plane of the slot-shaped depressions 29. Otherwise it is plug-in direction chamfer the upper edge of the webs 28, so that there is a run-up slope for easier insertion of the rod 4.
  • Stub 31 and tubular guide piece F are formed in the opposite direction in the zenith of the curved pressure ceiling 8.
  • the printing blanket 8 has a harmonica-like annular fold 40.
  • the zigzag folds running concentrically to the guide piece F take an acute-angled notch-like course.
  • the folding angle is approximately 40 °.
  • the fold closest to the rod 4 merges into the tubular guide piece F, forming a plug-in funnel.
  • the peripheral fold forms a circumferential clip projection 41, which engages in a matching annular groove 42 in the housing.
  • the annular groove 42 lies slightly below the housing cover 11.
  • the two described flexible printing blankets 8 return to the starting position after releasing the push button 7 due to the inherent restoring force.
  • pushbutton actuation surface 6 is formed by a linearly displaceable pushbutton 7, the other solutions use pushbuttons mounted in a tiltable manner. So comes in the case of the second embodiment Swivel lever engaging the central area on guide piece F. This pivots about a tilting edge 43 of the housing cover 11 which is formed by a recess and into which a tooth-like projection of the key engages. The tilting edge 43 is diametrically opposed to the decentralized output channel 26.
  • the pushbutton actuation surface 6 runs vertically.
  • a spring 9 rises obliquely to the top left. It is realized as a leaf spring and is supported on the wall of the vertical discharge channel 26, the opening of which ⁇ points transversely to the outside.
  • the top wall 47 is still surmounted by the mouthpiece output channel: .1 26.
  • the section of the pushbutton 7 which is exposed for actuation is enlarged somewhat further by cutting back the top wall 47 in a niche-like manner (cf. FIG. 5).
  • the pushbutton 7 is designed as a one-armed lever acting on the guide piece F in the central region.
  • the tilting point is formed by a plug-in recess 50 on the housing wall, in which a tooth-like projection of the pushbutton engages.
  • the other end leads in a window-like recess 51 in space 46 that limits the tilting movement.
  • the output channel 26 is an integral part of the push button 7, namely by molding a corresponding tube 52.
  • the guide piece F which slidably protrudes through the guide opening 10 of the housing cover 11, is connected to the push button 7 like a push button. For this purpose it forms with its upper edge section a bead-like male projection 53. The latter engages in one
  • Matrix opening 54 of a pipe socket 55 formed on the underside of the pushbutton The flexibility of the guide piece F, which is formed in one piece with the deformable pressure cover 8, compensates for tilting in the push button area.
  • the fourth exemplary embodiment is again a separate pushbutton 7.
  • This is pivotably mounted at 56 and has a sufficiently large central opening 7 'for the passage of a tube 52 which is angled here and onto which guide piece F is molded onto the pressure blanket.
  • Driving projections 57 which extend under the edge of the passage opening 7 ′ and thus transmit the displacement movement to the guide piece F, extend from the tube jacket wall transversely to the tilt displacement plane.
  • the limit stop for this movement also forms the front edge of the cap-shaped key body, which strikes the bearing 56 on the top of the housing wall 11.
  • At least one additional opening 58 is left in the attachment area between the connecting piece 31 and the pressure blanket 8. The latter enables the passage of a second component M 'upstream of the pasty mass, possibly with different colors.
  • All dispensers can be covered by a cap 59 in the mouthpiece area.
  • the mouthpiece opening ⁇ is closed by a stopper 60, so that drying out is effectively counteracted.
  • the piston area of the housing also has a sealing measure in that a film 61 is applied there.
  • This free-stretched film sits on an annular rib 62 outside the piston guide section.
  • the film extends immediately in front of the pointed end of the rod 4.
  • the piston 2 according to the embodiment of FIG. 1 is inserted from above by means of a sleeve. In all other cases without such an auxiliary tool from below.
  • the sleeve holds the prongs 3 'back from the inner wall of the housing. Only after pulling off the sleeve can the teeth hook into the housing wall.
