Definitions
- Dispenser for portioned delivery of liquids Y -I c and pasty masses
- the invention relates to a paste dispenser as described in the preamble of claim 1.
- suction and pressure valves are designed as hinge flaps, the opening and closing functions of which can be impaired by the hinge and adhesive forces.
- no measures are specified in order, for example, to achieve a tight closure of the extraction bore in the case of outgassing media.
- the invention is based on the object of proposing a generic paste dispenser which, with simple means, produces an intensive suction effect in order to achieve a high degree of filling of the pump chamber in conjunction with mechanical aids which additionally support the valve function and in order to ensure the emptying of a storage container which can be changed by negative pressure.
- the task is to open a closure of the extraction bore coupled to the actuation button before the start of delivery and to close it after the end of delivery.
- the dead space in the lower piston position tend towards zero and to establish a contact zone between the pressure valve and the suction valve in order not only to have the suction valve by negative pressure, but also by adhesive forces, which arise with the participation of the pasty mass in the contact zone, open as soon as the suction stroke begins.
- the pressure valve experiences an additional sealing force of its opening stroke, which is limited by stop edges on guide segments, together with the piston through the contact zone, so that the suppression generated by the piston does not increase the suction valve, but rather is available in full size for the suction of the paste.
- Another embodiment of the invention shows that the contact zone for driving the suction valve at the beginning of the suction stroke takes place by means of a plug-in cone which connects to the valve seat of the pressure valve and to which a corresponding hole in the suction valve is assigned.
- the suction valve is opened by the positive locking of the plug-in cone connected to the suction valve as soon as the suction stroke of the piston begins.
- the closing pressure of the pressure valve is increased to the same extent.
- a further embodiment of the contact zone between the pressure and suction valve is a friction rod which is firmly connected to the pressure valve and which is immersed in a bore of the suction valve, the fit being coordinated in such a way that both tightness and friction arise.
- the opening and closing movements of the suction and pressure valve are supported in both the suction and delivery strokes.
- a further design of the pressure valve consists in that guide webs are formed on the conical pressure valve seat in order to achieve an unturned longitudinal guide, and in the case of execution in plastic material a spring rod is formed, the lateral pivoting of which produces the suspension, which ensures the tightness of the pressure valve when Suction stroke supported.
- FIG. 3 shows a simpler design of the closure element connected to the lever button.
- a lid closure with flat surfaces is formed on the lever button, the lid closure being movable tangentially to the end face of the removal bore.
- a further advantageous embodiment specifies claim 18.
- the advantages that can be achieved with this embodiment are, in particular, that a dispenser that can be produced with simple means can be operated manually by finger pressure and that measures for achieving a high suction effect, for example, can be combined with commercially available tubes as storage containers, the material being able to be controlled by an automatically controllable closure can be protected from drying out, microbe infestation and storage losses without an additional closure cap and that the environmental impact is reduced by reusing the dispenser which can be separated from the storage container.
- the delivery piston can be moved in a cylinder that is free of internals, such as e.g. a compression spring and which is free of unusable spaces, which arise, for example, when designing suction and pressure valve zones.
- a further support of the suction behavior is seen in the fact that when the suction stroke begins to move, the suction valve is opened not only mechanically and without delay, but also via a detachable connection to the delivery piston. Adhesive and adhesive forces on the suction valve seat are thereby overcome and the filling of the cylinder space and thus a reliable function are guaranteed. It is expedient that the valve cone located in the delivery piston forms a receptacle with the delivery piston when it is in contact with the delivery seat, which receptacle can be filled by an attachment of the suction valve. This avoids secondary rooms that cannot be used for the suction process.
- the detachable connection between the delivery piston and the suction valve is formed by the receptacle and an extension, which are preferably conically tapered towards one another. Due to the conical design of the detachable connection, a positive connection between suction valve and delivery piston is produced in a simple manner, which causes a definable driving force.
- connection that can be released between the delivery piston and the suction valve has a lower, acceptable axial force than the holding force of the stroke limits on the segments of the suction valve. This ensures that the snap-in of the suction valve on the resilient stroke limits cannot be released.
- the releasable connection between the delivery piston and the suction valve has a lower absorbable axial force than the biasing force of the return spring associated with this position of the delivery piston. This ensures that the delivery piston or the dosing head can always return to its initial position.
- the return spring comes into contact on the one hand with a flange connected to the delivery piston and on the other hand with the housing. It is thereby achieved that the delivery piston, together with its internals, can be manufactured as a pre-assembly group and can only be inserted for assembly in the dosing head, since it is fastened via the return spring.
- the design of the delivery piston as a pre-assembly group consists in that a bushing is firmly connected to the delivery piston and serves on the one hand to support the compression spring and on the other hand comes to rest in the bore.
- An advantageous design of the dosing head is seen in the fact that a dosing head has an axis which is transverse to the axis of the feed piston and which has a control piston, a tappet and a valve cone in common. A space-saving, user-friendly arrangement of the mouthpiece valve is thereby achieved with simple means.
- control piston, tappet and valve cone can be produced in one piece and in flexible material and that the pre-setting spring can also be molded onto the control piston.
- control piston is designed as a pressure-tight, flexible disk which can be swung out like a membrane around its clamping point. This creates a low-friction, i.e. easily responsive and reliable sealing arrangement achieved.
- the disc can also be manufactured in one piece with a tappet and valve seat.
- control piston can be designed as a flexible, pressure-tight bellows, through the shape of which the valve cone resiliently comes into contact with the valve seat.
- a special design of the outside of the mouthpiece is achieved in that the mouthpiece valve has a front surface which merges into a half-shell or into a depression.
- Fig. 17 detail, wiping surface.
- a guide housing 1 (FIGS. 1, 2) is rigidly connected to a feed cylinder 3 via a flange 2. Both parts can also be produced in one piece.
- a feed cylinder 3 At the lower end of the feed cylinder 3 there is one Front wall 4, which is flush with a flat surface 5 of a suction valve 6, on the conical valve stem 7 adjoining guide segments 8, which are provided with stop edges 9 to limit the stroke.
- a thread 10 represents the connection to a storage container 11, which is preferably designed as a flexible tube.
- a delivery cylinder 3 there is a pump chamber 12, on the inner wall of which a piston 13 with its seal 14 is slidable.
- the end faces of the piston 13, consisting of seal 14, flat surface 16 of the closed pressure valve 17 (FIG. 2) form a plane.
- Guide webs 18 and a spring bar 19 are formed on the pressure valve 17 and can be swung out laterally and come to rest on a support surface 20 of the dosing head 21 and hold the pressure valve in the closed position.
- FIG. 2 In the actuated position, FIG. 2, the flat surface 16 of the pressure valve 17 touches the flat surface 5 of the suction valve 6. This contact surface between the suction valve 26 'and the pressure valve 21 is shown in FIG. 11 as contact zone b.
- the pressure valve 21 is followed by a plug-in cone 22 which has a small cone angle to the valve axis in order to achieve releasable driving liability in a corresponding recess of the suction valve 26 '.
- the 10 shows the contact zone c between the bore 25 of the suction valve 26 and a friction rod 24 which is firmly connected to a pressure valve 23.
- the contact zone c establishes a sealing and friction-generating sliding connection between the pressure valve 23 and the suction valve 26, whereby mechanical control of the pressure and suction valves 23, 26 can be achieved depending on the movement of the piston 13.
- the dosing head 27 in its simple embodiment contains a removal bore 28 which can be closed with a cap 29.
- a cylindrical sliding guide 30 is formed on the dosing head 27 and its length is intended to prevent it from tilting when actuated.
- the peripheral edge 31 forms the upper stroke limit with the stop 32.
- Axial slots 33 are provided on the guide housing 1 for radial expansion for the purpose of mounting the sliding guide 30.
- the piston 13 has at its upper end a flange 34, which lies sealingly against a corresponding flat surface of the dosing head 27, due to the return spring 35 which is clamped between the shoulder 36 and the flange 34.
- the dosing head 37 contains a mouthpiece 38, on the valve seat 39 of which a closure element 40 bears under the action of a compression spring 41.
- the closure element 40 is designed as a valve cone and is connected to a shaft 42 which is led out of the dosing head 37 through the bore 43, a sealing ring 44 coming into contact.
- the lever button 45 is pivotally mounted in a pivot point 46 and comes to rest on a collar 47 as soon as the lever button 45 is loaded.
- the collar 47 can be designed as a snap ring.
- FIG 3 shows a lever button 50 which engages on cams 51 and is connected to a closure element 52 which can be pivoted about the fulcrum 46.
- the latter is designed as a lid closure.
- the nose 53 connected to the lever button 50 rests under the action of the compression spring 54 on the dosing head 27 and generates a sealing force on the closure element 52.
- the paste dispenser consisting of the remaining parts is screwed onto the thread 10 onto the tube 11 filled with a paste.
- the air between suction valve 5 and tube 11 is to be removed by repeated finger pressure on the dosing head 27.
- the effective implementation of this measure is decisive for the further function and characterizes the advantageous embodiment of the invention.
- the opening of the suction valve 6 immediately at the beginning of the suction stroke with the participation of the adhesion in the contact zone a leads to an extraction of the air in the area of the thread 10.
- the suction valve closes in a known manner and resiliently by the spring rod 19 adjacent pressure valve 17 opens.
- a positive engagement is used to open the suction valve instead of the adhesive force.
- the plug cone 22 as a continuation of the valve seat 21 'of the pressure valve 21 is mounted in a corresponding recess in the suction valve 26'. With the suction movement of the piston 13, the suction valve 26 'is carried up to its stop edge 9. Then the positive engagement in the contact zone b is released.
- FIG. 1 and 2 show an embodiment which provides a closure on the mouthpiece 38 especially for media which dry or gas out easily.
- the closure element 40 is raised from its valve seat 39 by overcoming the pretensioning force of the drain spring 41, in that the lever button 45 moves the stem 42 by abutment against the collar 47.
- the lever button 45 contacts the stop 48 the closure element 40 reaches its maximum open position. If the actuating force on the lever button 45 increases further, the dosing head 37 with its slide guide 30 in the guide housing 1 is moved downward. It is advantageous in this embodiment that the delivery stroke of the piston 13 can only be triggered after the mouthpiece 38 has opened to the maximum, whereby smooth operation is achieved.
- the excessively long sliding guide 30 together with the guidance of the piston 13 in the delivery cylinder 3 prevents tilting.
- the return spring 35 lying outside the pump chamber 12, in addition to the arrangement of the valves, contributes to the fact that the dead space in the stop position of the piston 13 can be kept very small.
- the return spring 35 brings about a sealing contact of the flange 34 connected to the piston 13 on the dosing head 37.
- the open position of the pressure valve 17 shown in FIG. 1 occurs in the delivery phase, the spring rod 19 formed on the pressure valve 17 swiveling out.
- the spring bar 19 is guided around the shaft 42 in the area of the shaft 42 and bears against the support surface 20 in the center.
- a housing 101 is integrally connected to a cylinder 200.
- a thread 101 ' represents the detachable connection to a storage space 102', the storage container of which is not specifically shown.
- a suction valve 103 is flush with its plate surface 104 with a cylinder base 105 in the closed state (FIG. 13), while a conical extension 106 adjoining the plate surface 104 projects into a cylinder space 107 and in the lower stop position of a delivery piston 108 (FIG 13) releasably adheres in a conical receptacle 109.

- a flange 118 is integrally formed on the delivery piston 108 and serves to support a return spring 119 which is mounted in the housing 1 in the opposite direction.
- the return spring 119 also serves as a longitudinal fixation of the delivery piston 108 in the dosing head 120.
- a guide cylinder 121 which is connected to a guide cylinder 121, the stop 122 of which comes into contact with the knobs 123 in the unactuated position.
- the latter are stamped into the end face of the housing 101 after assembly.
- a slidable control piston 125 which is connected to a plunger 126 and at the end of which there is a valve cone 127 which has longitudinally oriented supply channels 127 '.
- valve cone 127 comes to rest against a valve seat 128, the surfaces of which are directed inwards towards the bore 124 '.
- Valve cone 127 and valve seat 128 form a mouthpiece valve 128 '.
- the positioning spring 129 is supported on the one hand on the control piston 125, and on the other hand on a cover 130 which is firmly connected to the dosing head 120 and has an air bore 131.
- the control piston is replaced by a flexible disk 132, which is fixed in a sealing manner at a clamping point 133 and can be pivoted about this on both sides.
- the control piston is replaced by a flexible bellows 135, the shape of which permits an axial spring preload which brings the valve cone 127 into contact with the valve seat 128.
- the adjusting spring 129 can be saved.
- FIG. 10 A special design of the wiping surface 136 of the mouthpiece valve 128 'is shown in FIG. 10.
- the wiping surface 136 is flush with a front surface 136 ′, which represents a cylindrical section through the dosing head 120 and merges into a half-shell 137. 17, the half-shell 137 is replaced by a depression 137 '. Both arrangements prevent excess cream from draining off or dripping off.
- the dosing head 120 is actuated for the first time, it is moved from the starting position (FIG. 12) to the lower stop position (FIG. 13).
- the drain valve 113 is opened by the compression pressure arising in the cylinder space 107 and the suction valve 103 is closed.
- the shoulder 106 of the suction valve 103 engages in the receptacle 109 of the delivery piston 108 and creates a detachable connection at this point.
- the delivery piston 108 forms a cylinder space 107 which corresponds to an approximate zero volume.
- valve cone 113 opens while the suction valve 103 is closed and a delivery pressure is formed in the bore 124 and 124 '.
