Definitions

  • the invention relates to a dispenser according to the preamble of claim 1.
  • DE-OS 36 05 419 proposes captive assignment of a closing means to a portioning version.
  • the actuating handle which can be displaced against a spring force, carries a sliding cover. In the basic position of the dispenser, this can then be pushed over the outlet opening of the dispensing tube which is stationary there.
  • a side effect is achieved in that the relocation of the actuating handle is blocked when the dispenser is closed.
  • This solution also depends on the user's mindfulness. If the latter forgets to move the sliding lid into the closed position, it will dry out too, forming an increasingly harder plug.
  • DE-OS 35 07 355 proposes a self-closing mechanism. Specifically, the procedure is such that the dispensing tube displaceable in the axial of the dispenser housing has a transverse axis on which a toggle button sits, which forms a slide with its free end, which is moved when actuated from the cross-sectional area of the outlet opening. The corresponding actuation takes place against spring force, which shifts the closing element back into its basic closing position when released.
  • the object of the invention is to make a generic dispenser more reliable in terms of use in this regard, without sacrificing the advantage of the self-closing function, and which above all also works more powerfully or more spontaneously.
  • a generic dispenser of increased utility value is achieved: the release conditions are triggered by the pressure conditions of the filling material. This brings great independence from its viscosity. Only the ready-to-open position is checked via the actuating handle. Specifically, the procedure is such that the dispensing tube is guided so that it can move in a linear manner in the actuating handle, the outlet opening being retracted behind a closure part in the unactuated position and, when actuated, the compression pressure causes the closure tube to extend.
  • the opposing shift from dispensing tube to actuating handle can be used not only to shorten the stroke, but also for the time factor; it comes for faster dispensing and clean, powerful ejection of the pasty mass.
  • the tube is practically "floating” or “free-floating” and can thus - subject to the free play of forces - adjust individually to the given conditions (friction, pressure).
  • the closing part is integrally formed on the actuating handle and the dispensing tube is guided in the actuating handle which is linearly movable in a stop-limited manner.
  • the inlet opening of the movable dispensing tube can be lifted off from a closing valve which is fixed to the housing or is formed on the actuating handle. The latter works extremely spontaneously and avoids emptying, so that there is always a portion of the mass that is always ready to be spent.
  • an advantageous embodiment with regard to the displacement of the delivery tube is that the delivery tube is surrounded at a radial distance by a guide sleeve and that the annular space created in this way is closed by a circumferential piston wall molded onto the delivery tube.
  • the piston means are housed in a very small space, using the already existing axial length of the dispensing tube, with favorable conditions regarding the support on the guide sleeve for the clean, low-friction mounting of the dispensing tube therein.
  • the dispenser mechanism can also be realized in the context of a pump chamber, be it with a bellows or pump piston.
  • the pump chamber is designed with an inlet valve and an outlet valve, the outlet valve can be opened on its guide surface with stop lugs and the outlet valve which is arranged displaceably inside the dispensing tube is connected to an inlet valve.
  • the illustrated dispenser of the exemplary embodiments has a long, cylindrical housing 1. Its base 2, which is designed as a standing surface, is spherically drawn in, so that there is a peripheral standing edge 3.
  • the end of the housing 1 opposite the bottom 2 has a flange 4 following a neck portion 5 that is drawn in significantly behind the diameter of the housing.
  • the housing 1 there is a previously introduced, cup-shaped piston 6. Its lip 6 'lead on the cylindrical housing inner wall 1'.
  • the floor 2 has a central opening 7 for air compensation.
  • a central protrusion 8 of the piston 6 projects into it, initially sealingly.
  • the protrusion 8 extends from the bottom of the cup-shaped piston 6 and is hollow.
  • the protruding area of the projection has the shape of a truncated cone, which on the inside of the housing merges into an annular shoulder which rests on the opening edge.
  • the upward end region of the housing 1 opposite the base 2 is equipped with a device V for dispensing the dispenser contents in portions.
  • a device V for dispensing the dispenser contents in portions.
  • the content of the donor it may be pasty mass M, such as toothpaste.
  • Part of the device V is a pump chamber 9. This has a bellows 10 which is compressible in the longitudinal center axis xx of the dispenser and is supported at the bottom. This forms a cylindrical one Ring groove 14 with rotationally symmetrically converging inlet flanks 14 '.
  • the insert body 13 is, overlapping the conveyor rim 4 of the housing 1, essentially in the interior of the housing 1.
  • the overlap is realized as a sealing bounce or snap-in connection, for which purpose the upper edge of the essentially cylindrical insert body 13 is in an overlapping, flat annular flange 15 continues with subsequent axially oriented locking lip 16. Seen in cross section, there is a groove-forming contour. This locking groove bears the reference number 17.
  • Another ring collar 18 facing away from the piston is connected to a movable component of the device. It is a head piece 19 which can be displaced in the interior of the insert body 13 and is guided in a limited manner in the longitudinal central axis xx. This also essentially cylindrical shape, is in the dispenser closed position about a third of its length in the cylindrical cavity of the insert body 13. This overlap area is for Guidance and limit stop used.
  • the lower edge of the head piece 19 has an outwardly directed guide rib 20 and a locking rib 21 formed on its cylindrical outer surface, spaced apart from the guide rib 20, which in the basic position occurs against a flange-like counter rib 22 of the insert body 13.
  • the supporting system results from the restoring force of the bellows 10, which is embedded with a certain preload.
  • the ring collar 18 enters the ring groove 23 of the movable head piece 19 in a position-secured manner.
  • the latter and the insert body form the pump housing of the device V.
  • a helical compression spring would be used to secure the basic position of the dispenser.
  • the head piece 19 has an easily accessible actuation handle B.
  • the latter consists of a cover plate 24 which closes off a portion of the cylindrical head piece 19.
  • the latter is plugged into the head piece 19 in a plug-like manner and covers the free end of an output tube which forms the heart of the dispensing mechanism at the top y 25.
  • the latter is angular. It has a vertical tube section a running in the longitudinal central axis x-x and a radially directed tube section b extending at a right angle.
  • the dispensing tube 25 is guided linearly in the actuation handle B.
  • a guide sleeve 26 of cylindrical shape is used for this purpose. It is molded onto the head piece 19 and arises from a transverse wall 27 of the head piece 19 which forms the annular groove 23.
  • the guide sleeve 26 which runs concentrically to the cylindrical wall of the head piece 19, ends at the level of the underside of the tube section b. Equal in height to this also closes a window edge 28 'formed by the head piece 19' of a window 28 open towards the transverse side, from which window edge 28 'the dispensing tube 25 is supported in a stop-limited manner.
  • the leading inside of the guide sleeve 26 runs circumferentially at a radial distance z to the outer wall of the Tube section a.
  • the annular space 29 thus present is cross-closed by a piston wall 30.
  • This piston wall there is an annular lip with a bevel on the piston side, so that the plug-in assembly is facilitated.
  • the piston wall 30 running continuously on a cross-sectional plane is in the basic position in the lower third of the longer tube section a.
  • the support is provided via longitudinal ribs 31, which are arranged in a star shape on the lateral surface of said tube section, at least three in number.
  • the end faces of the longitudinal ribs are chamfered, ie beveled, to improve the sliding ability.
  • the piston-side inlet opening 25 'of the dispensing tube 25 overlaps a closing valve 32 which is fixed to the housing in the present case. It is a stopper-like expression of the transverse wall 27 directed towards the inside of the tube movable part, namely on the actuating handle B, that is to say the head piece 19 and the associated valve seat surface also on a part movable relative thereto, namely the dispensing tube 25.
  • the closing valve 32 stationary, for example on an extension arm of the housing 1 to store.
  • the transverse wall 27 carrying the closing valve 32 is broken.
  • the opening begins at the plug base of the closing valve 32 and extends in shape a plurality of radial slots 33 in the direction of the annular groove 23 without naturally affecting it.
  • An inlet valve V 1 is then located in the bottom 12 of the insert body 13.
  • This is designed as a valve plate, the valve seat surface of which extends from the end edge of a collar 34 that licks out in the direction of the pump chamber 9.
  • the stop lugs 36 formed over these define the valve lift and thus bind the valve body in the cylindrical collar 34.
  • the inlet valve V 1 and the closing valve 32 which can also be referred to as an outlet valve, control the mass flow in portions.
  • the inlet valve V 1 is designed in the same way as the inlet valve V 1 of the first embodiment. However, it sits over an axial shaft 37 in the exhaust valve V 2 continues. The latter is located inside the dispensing tube 25. In the basic position, the outlet valve V 2 is located approximately at the level of the piston wall 30.
  • the outlet valve V 2 consists of two valve flaps 37 'starting from the head of the shaft and having the same area size. When flowing through the mass, the two valve flaps 37 'fold together practically like a book page (see FIG. 5).
  • the valve flaps assume a Y-shape in the sealing position, i. H. the valve flaps diverge upwards. In this position, they assume an edge-tight contact with the inner surface of the dispensing tube 25.
  • the valve flaps 37 ' can be slightly tapered towards the free ends and are made of flexible material with sufficient restoring force.
  • the outlet opening O has moved behind a stationary closure part 38 (cf. FIGS. 1 and 4).
  • this closure part 38 is a vertical wall section of the head piece 19, and shown that the part of the wall forming the closure part 38 forms a flat surface 38 'on the inside, which runs parallel to the end face 39 of the tube section b.
  • the upper front edge is designed to a cutting edge 38 ⁇ .
  • the vertical wall section forming the actual closure part 38 continues via at least one approximately radially directed side wall 40 into the cylindrical jacket wall of the head piece 19.
  • two side walls 40 are expediently formed, which, coordinated with the outer diameter of the tube section b, create a vertical guide shaft 41.
  • the leadership shaft 41 is left open at the bottom. As a result, paste residues cannot lead to a shortening of the vertical movement stroke of the dispensing tube 25.
  • the guide shaft 41 merges into the window 28 of the head piece 19. In the actuating position, however, the horizontal tube section b does not leave the guide shaft 41, since its side walls 40 continue to rise obliquely upwards beyond the upper edge of the cutting edge 38 ⁇ .
  • a soft spring 42 is located in the area of the distance y above the tube section b. It is, for example, an inclined leaf spring. This is either molded onto the top of the tube section b in the manner of a cock's comb, or else the inside of the corresponding cover side of the cover plate 24 is injection molded.
  • the housing 1 can also hold liquid, in which case a riser pipe, not shown, would then emanate from the bottom 12 of the insert body 13.
  • the insert 19 would have a small passage opening for the necessary air balance, expediently in the area of the collar 11, which could take over valve function. The hole would then lie in the area of the said collar which is not contained.
  • the actuating handle B forms in the center of the cover plate 24 a small pin 43 which projects upwards therefrom.
  • the finished, filled product has a dispenser protective cap 44 covering the mechanics.
  • the edge thereof has a tamper-evident device 45 in the form of a ring which engages under the locking lip 16.
  • a notch groove 46 (FIG. 2).
  • the ring has a pull tab, not shown.
  • the top-side support of the protective cap 44 form on the inner wall of the cup-shaped cap body formed longitudinal ribs 47, which rest on the flat ring flange 15 with their underside.
  • the function is as follows: After removing the protective cap 44, the actuating handle B is accessible. Applying pressure in the direction of arrow P leads to a reduction in the volume in the pump chamber 9 due to the pump bellows 10 being compressed when the discharge path is already filled Pressure device.
  • This shooting up of the dispensing tube 25 firstly removes the closed position of the dispensing tube by moving its outlet opening ⁇ out of the area of the closing part 38, and secondly opens the closing valve 32, since the relevant inner end section 25 ', i.e. the inlet opening of the dispensing tube stands out from it.
  • the actuating handle B or the head piece 19 is moved downward relative to the stationary insert body 13, the inlet valve V 1 remains closed due to the compression pressure in the pump chamber 9.
  • the tube section b which has moved upward by the distance y, has entered a complete release position so that the strand of the pasty mass is applied cleanly. This happens due to the increasing compression pressure and the spontaneous, overlaying pushing of the dispensing tube 25 in the opposite direction, it is also quite rapid. If the actuation button B is released after the application, the spring force of the bellows causes the return to the closed position, ie the head piece 19 extends again. This results in a vacuum in the pump chamber 9, which vacuum lifts the inlet valve V 1 from its valve seat surface, so that paste-like mass M is sucked into the pump chamber 9 from the supply. The piston 6 is pulled over the level column by the corresponding volume fraction.
  • the inlet valve V 1 does not even have to step into its closed position, which is conceivable taking into account the frictional forces and the pasty mass, so that even a constant moisture connection of the portion enclosed in the pump chamber 9 to the residual mass M in the housing 1 is given.
  • the piston 6 has a structure which ensures that the pasty mass is dispensed as completely as possible.
  • the function of the dispenser according to the second embodiment (Fig. 4 and 5) is essentially the same, both in terms of the self-closing effect and the output, only that when output by the scoop-like function of the exhaust valve V 2, a portion of the strand relative is pushed out for tube movement, since this outlet valve V2 is connected via the shaft 37 to the inlet valve V1 which has entered its closed position. If the head piece 19 is shifted further downward, this strand section which is actively pushed out is supplemented by one which is caused by the compression pressure, that is to say corresponding displacement forces. The valve flaps 37 'then lie against each other (see FIG. 5), so that the exhaust valve is washed by the mass flow.
  • the dispensing tube 25 occurs, possibly also supported by its own weight, again in the closed position, caused primarily by the above-described effect of the piston wall 30.
  • the contact of the valve flaps 37 'on the inner wall of the dispensing tube 25 also brings with it a certain increased friction , so that the inlet valve V1 connected via the shaft 37 is even actively closed.
  • the head piece 19 forming the actuating handle B. and the tube 25 perform relative movements during the upward and downward movement of the head piece 19, in the following exemplary embodiments the actuating handle B and the tube 25 are rigidly connected to one another or in one piece to one another.
  • the head piece 19 guided in the cylindrical insert body 13 is connected to the tube 25 via an inner radial shoulder.
  • the bellows 10 is held between the annular grooves 14, 23.
  • the actuation handle B1 is placed, which has a hole in the center through which the tube 25 is guided.
  • the pump chamber 9 is delimited by the bellows 10, the aforementioned inner radial shoulder and the bottom 12.
  • the method of operation corresponds to the embodiment according to FIGS. 4 and 5 with the exception that there is no relative movement between the tube 25 and the head piece 19.
  • the bellows 10 has been eliminated.
  • the pump chamber 9 is in each case delimited by the base 12 and a cylindrical wall 125 of the insert body 13, which can be in one piece with the wall 1, and the tube 25 designed as a piston, which is guided in the cylindrical wall 125.
  • the dispenser is formed in the head region with two annular chambers 123 and 124.
  • the annular chambers are drawn in in opposite directions, designed in one piece with the dispenser housing 1.
  • the outer annular chamber 123 is open at the bottom, towards the inside of the dispenser, and the inner annular chamber 124 is at the top.
  • the inner wall 125 of the inner annular chamber 124 simultaneously forms the wall of the pump chamber 107 and Pump chamber 6 according to the embodiment.
  • a spring 126 is disposed in the inner annulus 124. Because the pump chamber 107 is formed in this exemplary embodiment by the outer cylindrical space of the wall 125 of the inner annular chamber 124, the spring 126 is arranged in a space through which no mass flows.
  • the likewise cylindrical wall 127 between the outer and inner annular chamber merges into the dispenser housing 1 via the connection 128.
  • FIG. 9 shows the dispenser head of the embodiment according to FIG. 8 in the depressed position.
  • the inlet valve V1 and the outlet valve V2 the same characteristic results as described above with regard to FIGS. 5 to 7.
  • a piston 131 of the pump chamber 9 is arranged directly in the area of the inlet opening 130 on the dispensing tube 25, which in the rest of this version is angled in its upper region with a lateral outlet opening ⁇ .
  • the spring 126 is supported in the lower region on a connection between the cylindrical walls 125 and 127.
  • vertically extending struts 133 are drawn into the annular chamber formed by the dispensing tube 25 and the outer cylindrical wall 132 of the actuating handle B2, which struts form a stop for the spring 126.
  • connection 128 which are connected to the closure part 38 are connected to each other and against which the opening ⁇ comes into contact when not in use.
  • the window 28 is provided beneath the closure part, so that the material can escape from the tube 25 when the actuating handle B2 is actuated.
  • the exemplary embodiment according to FIGS. 10 and 11 relates to a dispenser for liquids.
  • An intake hose 135 is fastened in a nozzle 124 below the inlet valve V1.
  • the dispenser according to FIG. 10 has a pivotable spout 136 which is pivotably attached to the dispensing tube 25. 11, the spout 136 is in the pivoted-out position.
  • the swivel spout 136 is important for the assembly of the dispenser head. When the nozzle 136 is depressed, as in FIG. 10, the pump head can practically not be compressed.
  • FIG. 12 shows the upper part of a dispenser, otherwise according to FIG. 9 in the depressed position.
  • an alternative exhaust valve V2 is implemented. It consists of a valve flap hinged to 240 in the dispensing tube 25.
  • the outlet valve V2 and the inlet valve V1 are therefore no longer connected to one another in this version. You can move independently of each other. It is special that the outlet valve V2 is mounted in the piston-like movable outlet tube 25, that is to say - in a stationary manner relative to the dispensing tube 25 - the movement of the dispensing tube 25 is carried out.
  • the dispenser consists of a lower cylindrical housing 1 and a dispenser head, which is designated overall by V.
  • the dispenser head V is covered by a cap 44.
  • the cylindrical dispenser housing 1 can be screw-connected to the dispenser head V.
  • the dispenser housing 1 has in its upper end region a cylindrical extension 141 which is designed with an internal thread.
  • a connector 142 is screwed into this extension 141.
