Description

The invention relates to a dispenser for portioned issue pasty Masses, with a tubular housing in which a piston is in Entleerungsbetätigung gradually shifted towards an emptying spout, which a depressible in the direction of the piston, operable via a handle Crimping head and the opening cross-section of the emptying spout occlusive Lid is assigned.

A crimping head with this assigned emptying spout results from the EP-A1 0 214 106. The cover to be kept open the opening is part of a handle mounted about a stationary pivot. About this one becomes Neck of the squeezing head relative to a piston-like mating end of the emptying spout moved like a pump. Releasing the handle enters the lid in use of the restoring force of the crimping head back in his Closed position.

From DE-A1 37 16 822 a generic dispenser is known in which the crimping head is actuated via a pivotally mounted, separate handle becomes. The actuating force is via bending sections in the crimping head initiated. The bending sections are of such length that they are different Compensation for movements between the handle and the crimping head. When actuated, the opening cross section of the emptying grommet rises practically axially from the stationary cover.

From US-A-4 991 744 a dispenser with in Indentation of the squeezing head slidable Turn-tenon connection according to the preamble of Claim 1 known.

The object of the invention is structurally simple, a generic dispenser as well as easy to handle.

This task is done by a donor the features of claim 1, by a Turn-tenon connection between cover and drainage spout in conjunction with a slot / pivot bearing between Lid and housing.

According to such a configuration is a structurally favorable, use-advantageous Solution: The pivot-and-pin connection not only covers the usage mode of the rotary pivot for the handle, but also acts as Connecting element between two main parts of the dispenser mechanism. The practically leads to a direct operation and otherwise structurally to a simplification. Optionally form lid and handle one unity. The Slot / trunnion bearing between lid and housing is designed such that the pivot pin after partial Öffnungsverschwenkung the lid under Carrying the emptying grommet by support on a housing fixed Abutment in Eindrückrichtung the crimping shifts. Such a Slot can be considered on the housing side right away. His design is so that it only after partial opening movement of the lid to a carry-along the emptying spout and thus actuation of the pump comes. The guarantees a clean output. This is reflected in increasing usage time also down in the exterior; it does not require constant cleaning of the dispenser head. In return, by the first-onset reset the crimping head a possible board on pasty mass from the emptying nozzle mouth or the opening cross-section of the same, So absorbed. A convenient handling is the measure that the Lid preferably expires in a pimple-like projection. Such an exposed one Advantage is leverage and safely accessible or tangible. Furthermore This results in a self-stiffening of the entire lid, so that's right can be worked thin-walled. With regard to the mechanical side proves It is advantageous that the abutment from one in the direction of Turn-pin is formed sweeping wing, against the underside of which Flank of one arm of the lid bumps. At the bottom stands the said Arm in the area of the pivot-pin connection from under compression of the squeezing head. It is further provided that the lower edge of the lid in dips a matching groove of the housing. The whole thing happens preferably in a way that on a conventional cap or overcap can be dispensed by the lid with its other characteristics integrated into the shape of the dispenser head, this in the sense of an undisturbed, almost flush transition from moving part to the fixed part. Finally, it proves to be advantageous in terms of actuation that the pivoting of the lid until the release of the emptying spout opening cross section is greater than the residual swing of the lid for the Push-in movement of the squeezing head. This allows the opening cross section Priority largely expose so that a targeted, free visual traceable application is achieved safely.

another view of the donor.

The illustrated dispenser Sp is realized as a standalone unit. He has a tubular Housing 1. The latter has a the donor mechanism 2 containing above Dispenser head 3 on. Below, the housing 1 is in a widened Stand 4 continued.

The one-piece with the housing 1 dispenser head 3 is protected by a protective cap. 5 Coverable in times of disuse. It can be attached frictionally be and takes place on an annular shoulder 6, achieved by a Wandungsversatz the cylindrical housing 1, their limit stop.

The vast length of the housing 1 is used in terms of volume as Pantry 7. He picks up pasty mass 8. This can be a Main mass act, for example, to toothpaste.

The pasty mass 8 can then be superimposed by a further pasty mass be. This is located mainly in the base area of the dispenser head 3 and represents an additional mass, for example. In the form of a mouthwash component. Latter settles in a known manner strip on a portioned output formed strand on. The dispenser mechanism 2 acts in this regard pump-like ausbringend. A device forming the strip structure is shown in FIG Drawing not shown. However, it arises, for example, from the introductory acknowledged DE-A1 37 16 822.

The lower end of the storage space 7 forms a piston 9. The is as Follower piston realized. It is inserted from below into the housing 1 while fulfilling the cover function.

The piston 9 is only in the emptying direction arrow x corresponding to the emptying operation gradually relocatable. This leads to peripheral lips 10 of the piston 9 on the cylindrical inner wall 1 'of the housing first

On the side facing the pedestal 4 side of the piston 9 carries a so-called Clamping module 11. The usually has radially aligned Zakken. Such a pointed star made of spring steel has, brought into the plane, one circumscribing diameter greater than the clear diameter of the cylindrical storage space 7. Accordingly, the slightly sloping dig Piping ends like support feet in the corresponding hookable in this regard Inner wall 1 'a. The whole is through an outer plate 12th covered. Further technical details of such a Klemmgesperres are the State of the art in various forms removable. It should therefore be a further explanation omitted.

The heart of the pasty strand ausbringenden pump for the piston. 9 represents a dome-shaped crimping head 13. The similar to a pump bellows Crimping head 13 is made of rubber-elastic, resilient material and extends in the base area of the dispenser head 3. It is specifically in the transition area between pantry 7 and dispenser head 3, in an annular groove 14th held, received on the inner wall 1 'of the housing 1. The upper Flank 15 of the annular groove 14 results from the annular shoulder 6 stellenden Wall offset of the housing 1; the lower edge 16, however, forms a transversely convex annular rib 17.

The compressible, pump-active region of the crimping head 13 is in the described bracket not included. Stucked axially is rather one of the lower end edge 13 'of the dome-shaped squeezing head 13 outgoing, in the emptying x freestanding converted, cylindrical Cuff 13 ", which overcomes the plug assignment otherwise the holder serving annular rib 17 and snaps into the annular groove 14 a.

The application of the strand to pasty mass 8, including if necessary the stripe-like component is done on a relative from rigid material existing emptying spout 18. The emptying spout 18 is realized as an angle tube and has a strand-forming channel 19. The emptying spout 18 is accordingly made of an angled, freestanding to be released section a and coaxial with the longitudinal central axis y-y of the basically rotationally symmetrical dispenser Sp extending, vertical Section b together. The included inclination angle alpha is included 45 °. Reference is made to FIG. 4. The opening cross-section forming a donor mouth 20 of the emptying spout 18 is in the basic position of the donor Sp overlapped by a cover 21 closing.

The lid 21 is of a hood-like shape. He has both implied Sense closing function as well as pump-actuating. For this he represents at the same time the handle H. cover 21 and handle form a unit. It deals It is a one-piece body in the form of a spiked helmet.

The exercise of the function is done via a rotary-pin connection DV between Lid 21 and the emptying spout 18. The pivot pin is designated 22. It is provided in pairs and can be latched over ramps in stock.

The storage is made stationary; It takes place in the dispenser head 3. Of the has a slot 23, also in paired design. The slot 23 is in the operating position of the lid 21 of FIG. 7 by breaking this Figure visible.

The slot 23 is formed as a slot. This runs in the direction of the pushing-in movement of the crimping head 13, ie opposite to the direction of the arrow x.

Accordingly, the pivot-pin connection DV, respectively Slot / pivot pin bearing 23/22 between cover 21 and housing 1 made so that the pivot pin 22 after partial Öffnungsverschwenkung the lid 21 (see Fig. Position of FIG. 6) with towing the Emptying spout 18 by support on a housing-side abutment W moves in Eindrückrichtung of the crimping head 13.

To implement this displacement movement in the compression position the crimping head 13 is the other, lower end 18 'of the emptying spout 18, the section b, then, in non-displaceable, d. H. solid plug connection with the crushing head 13 which can be pressed in the direction of the piston 9. The corresponding plug-in end 18 'of the vertical position in the basic position Section b of the discharge spout 18 is in a zenith of the dome-shaped Crushing head 13 standing neck 24 of the crimping head added. The corresponding slip-free composite is achieved by meshing of Ring beads 25 of section b in corresponding annular grooves 26 in the neck interior the crimping head 13.

For a priority exposure of the opening cross-section 20 against the subordinate strand application can be designed as a cover lid 21st in the area or environment of the dispenser head 3 to a relatively large mouth 27th to open. Reference is made to FIG. 6. The structural vote regarding the Dispenser mechanism is accordingly such that the pivoting of the lid 21st until the release of the emptying spout opening cross-section 19 is greater than the Restschwenkweg the lid 21 for the Eindrückbewegung of Crimping head 13. The first pivoting path, based on the pivot pin 22, supported in the upper end 23 'of the slot 23, closes an angle beta of about 90 °. The freiragend projecting portion a of the emptying spout 18 extends at completely open mouth 27 in the bisector of the said Winkels Beta.

The movement in this intermediate position of the lid 21 subsequent Schwenkweg, referred to as Restschwenkweg, however, closes an angle Gamma of about 40 °. In reaching this operating position, shifts the pivot pin 22 in the housing-fixed slot 23 limited down, incoming in the local, ie lower end 23 "of the slot 23.

The lid 21 is designed in principle double arm, and with respect to the rotary pivot pin 22 rotational pivot axis.

The one, in the range of action of the abutment W can be brought arm of the Dekkels 21 is designated I. In the basic position (see Fig. 5), this arm is I suspended, d. H. he points with his free end against the Crimping head 13. In this position holds a hood-like section, lasting in this helmet metaphor, with the inside of an eyeshade 28 as the actual one Closing portion of the opening cross section 20 of the emptying spout 18 to (See also Fig. 4).

Now, the lid 21, at the same time acting as a handle H in a clockwise direction around which at the upper end 23 'of the slot 23 initially pivotally supported Rotated pivot 22 pivoted, the result in accordance with the position Fig. 6. This is noticeable limited stop defined by the entry of a Flank 29 against the stationary bottom 30 of the abutment W.

The abutment W is projecting from a in the direction of the pivot pin 22, easily formed in the mouth contour rising wing 31. Whose edge 29 is recognizable thickened compared to the rest of the wall area. The actual underreaching area consists of a raised cross-round roof-like sloping flanks 29. The cross-rounding avoids planing removal between the arm I and the abutment W. The bottom 30 shows the slot-longitudinal center.

In the position shown in FIG. 6, the arm I takes a substantially horizontal Position or vertical alignment with the longitudinal center axis x-x of the dispenser Sp one.

The other, designated II, practically in the area of the neck of the Helms lying arm of the lid 21 and the hood is the actuating arm. He is specially trained friendly. He runs into one the general Haubenform centrally protruding projection 32. This lengthens the lever arm and gives the lid 21 the distinctive pimple-like shape. The tip of the projection 32 is broken.

In the area of the side screens of the helmet is the slot / pivot-pin bearing 23/22 settled. It sits, as it were, in the apex of a rectangular sighting opening, realized in the region of the lower edge 33 of the lid 21st

The lower edge 33 of the lid 21 occurs in the basic position of the lid 21 in a matching shaft-like recess groove 34 of the housing 1 a. The latter is on Dispenser head 3 is formed, wherein in the pivoting plane of the lid 21 extending Wall sections of the recessed groove 34 used as guide surfaces are. The cover-side wall sections are correspondingly feasible designed.

The designated II arm of the lid 21 proposes Ausschwenkbegrenzend against a fixed stop 35 of the dispensing head 3 (see Fig. 7).

On the other hand, the free end of the arm I also strikes against a corresponding inner surface of the dispenser head 3. This stop bears the reference numeral 36.

As can be seen from the drawings, the pivot pin 22 is the Slot / pivot-pin bearing 23/22 laid from the longitudinal center axis x-x, in a direction away from the opening section 20 direction.

To achieve a highly stable connection zone between the lid 21 and Discharge spout 18 is the spout-side part except through the tube shape itself still stabilized by the jacket wall of the vertically extending portion b the emptying spout 18 molded longitudinal ribs 37th

The function is, briefly summarized, as follows: By exercising a Pivoting movement of the cover 21 in a clockwise direction, ie in the direction of the Arrows z, the closing portion of the lid 21 is out of range the opening cross-section 20 moves. This leads to the application of the Stranges optically easy to track making freestanding in concise concave Maul 27. With going through the pivoting path according to angle beta connects the opening phase now an actuation phase. The opening phase finds articulated about the upper end 23 'of the slot 23 instead. With undercut of the Poor I under the windowsill-like wings 31, this arm I now forms the Tipping point for a further lowering of the lid 21 over the other arm II as a handle H. The pivot pin 22 displaced piston side in the slot 23rd The pivot pin 22 is thus displaced down and with him the emptying spout 18. Since this is firmly connected to the crimping head 13, the Crimping head 13 using the determined by the slot 23 Hub 38th pressed together. This leads to a compression of the pasty mass 8 According to volume reduction in the crimping head 13. The mass 8 is, over the Channel 19 emptying spout 18 going strangportioniert expressed.

Releasing the handle H, respectively the lid 21, the emptying spout turns 18 according to the restoring force of the crimping head 13, acting as a return spring of the dispenser mechanism 2, again in the of Fig. 5 apparent Basic position back. This is done by passing the Restschwenkweges according to angle gamma as well as the pivoting path according to angle beta. Under Exercise of the so-called Selfclosing effect will continue on the Level column of the pasty mass 8 of the piston 9 in the housing 1 by one Step by step. In the new level, he gets involved with the above Clamping module 11 in the cylindrical inner wall 1 '.

Any supernatant at mass 8 and optionally an overlying mass component, is sucked back behind the opening cross section 19.

To increase the restoring force, the dome-shaped crimping head 13 on the ceiling side inside a rib-Strebwerk 13 "'on.

A part of the throat-like contour of the mouth 27 is from the lower section b the emptying spout 18 in the form of an associated or emanating from it latzartigen Lappens 39 contributed. The finds in basic position in a contour-adapted opening 40 of the dispenser head 3 recording and is under the operation of the dispenser together with the emptying spout 18 with lowerable.

The handle H is best in terms of their gripping surfaces for the operation equipped. Leave over the pimple-like pointed projection 32 Conveniently initiate the operating forces well. The donor Sp can be like operate a hand-held classic-style lighter.
