Definitions
- the invention relates to a dispenser for the simultaneous dispensing of flowable, for example liquid and / or pasty media with a storage device having at least two storage chambers and with a pump head attached to the storage device in the assembled state of the dispenser and provided with an applicator , wherein in the pump head • each pump chamber is assigned a pumping element, and the pumping elements can be acted upon simultaneously via an actuating device for dispensing medium.
- Such dispensers are suitable for two- or multi-component mixtures, the components of which can be stored poorly or only to a limited extent in the mixed state, since, for example, the components in the mixed state are reactive with one another or can only be used for a limited time, or for longer periods Quiescent separation processes occur.
- differently large forces are necessary to dispense medium when dispensing at the individual pumping organs.
- a dispenser of the type mentioned which has an elongated oval basic shape in horizontal cross section.
- the actuating device of the known dispenser has a sleeve-shaped actuating member which is adapted to the horizontal cross section of the basic shape and is closed on one side and encloses an upper end of a storage device.
- Outflow channels for the mixture components run in the actuating member, the mixing of the components taking place within the actuating member.
- the volume of two pumping chambers can be reduced by depressing the actuating member, the respective components being pressed into the outflow channels.
- the outlet opening is also arranged on a broad side of the actuating member.
- the actuation is therefore usually carried out by finger actuation from the opposite broadside. If the finger force is now not applied exactly between the pumping chambers, this results in a tilting moment acting on the actuating member about the shorter transverse axis of the basic shape cross section and about its longer long axis.
- a dispenser similar to this known dispenser is also known from EP-B1-0 243 667, in which the actuating member can also be tilted and thus uneven dispensing is possible.
- a part of the pump mechanism is also arranged in the storage device, so that the exchange of the storage device becomes cumbersome, or a part of the pump mechanism itself has to be thrown away.
- Another dosing pump dispenser is known from DE-Cl-41 20 644, in which, in contrast to the known dispensers already mentioned, the pumping organs are actuated by a swivel lever.
- This pivot lever is articulated on the edge of the dispenser, with a relatively strong curvature of the path of the conveying stroke being obtained for the displacement body of the pumping goose located closer to the pivot axis.
- it is therefore necessary to make the pumping chambers flexible with regard to their distance from the pivot axis by means of a bellows.
- the flexibility of the bellows favors an inflation effect, which makes it difficult to precisely set and adjust a desired mixing ratio.
- the invention is based on the object of creating a dispenser of the type mentioned at the outset which enables a high uniformity of the mixing ratio during the entire dispensing stroke or also a partial stroke and thereby enables easy handling with optimal use of the stored media.
- the straight guides also increase the rigidity of the actuating device and furthermore make it possible to avoid an air cushion effect when actuating. Due to the increased tilting rigidity of the actuating device, the latter can also be loaded asymmetrically without deteriorating or changing the metering accuracy and the mixing ratio. Thereby, the constructive S is pielraum ver ⁇ for forming the actuator RESIZE ert ß, which is now easier to check ergonomically favorable forms ish can be fitted to allow improved grip of the dispenser.
- the width of the pump head in the direction of the transverse axis is smaller than in the direction of the axis connecting the pump organs. This results in an improved rigidity of the actuating device in the region of the tilt axis relevant for the dosing accuracy.
- the applicator of the pump head points in the direction of a narrow side thereof, an actuating section being arranged on the narrow side of the pump head opposite the applicator. This results in an ergonomically favorable position of the dispenser in the hand and thus good handling. If the applicator is facing up, i. H. In its orientation, which is designed to point away from the standing surface of the dispenser, outflow ducts of equal volume can be achieved, so that the mixing ratio is set correctly already at the first dispensing.
- two straight guides are provided at an equal distance from the axis connecting the pumps, whereby an optimal distribution of forces on the straight guides is achieved.
- a separate outflow channel is provided for each medium, which leads from the respectively associated pump element to an associated outlet opening provided on the applicator and pointing to the surroundings.
- the coaxial arrangement of the outlet openings of the outflow channels with respect to one another enables the sheathing of an inner strand in order to reduce or prevent premature reactions of this medium with the environment.
- the storage device is designed as a one-piece component which has two separate storage chambers and which is detachably and interchangeably connected to the pump head containing the entire pump mechanism via a plug connection.
- This enables the storage device to be replaced easily and thus the pump head to be reused.
- the arrangement of the entire pump mechanism in the pump head enables optimal resource conservation since no complicated parts have to be thrown away.
- the storage device is handy as a one-piece component and can be easily assembled.
- a sealing sleeve made of flexible material is provided for each pump element between the pump cylinder and the actuating device. This additional seal prevents the mixture of media escaping from the pumping chambers as a result of possible leakage, as a result of which undesired reactions in spaces between the pump head, eg. B. the curing of the mixture can be reliably avoided.
- all components of the dispenser are designed as plastic injection molded parts, preferably made of recyclable material. This enables reused pump heads to be reused without having to be dismantled beforehand. Exemplary embodiments of the invention are explained in more detail below with reference to the drawing.

- the volume of a pump chamber formed between piston 80 and pump cylinder 91 is reduced by depressing the actuating device 4, so that medium contained in the pump chambers through the first non-return devices 130 into corresponding outflow channels 62a, 62b is pressed and flows out via associated outlet openings 63a, 63b of the applicator 61 of the distributor 60.
- the second non-return devices 140 remain closed.
- a return spring 120 is provided, which is arranged between the head piece 90 and the adapter 70.

- the support 160 is designed as a sleeve-shaped body which surrounds the storage device 2 and is provided on its narrow sides with openings running from the floor to near the head piece 90 in order to enable the storage device 2 to be exchanged easily.
- an apron 100 is fastened to the head piece 90, which blinds the movable parts of the actuating device 4.
- the apron 100 also has a ring shoulder for attaching a cap enclosing the pump head 3.
- the storage device 2 as well as the pump head have an essentially elongated, preferably oval basic shape in the horizontal cross section.
- the storage device 2, the head piece 90 and the pump elements are arranged symmetrically next to one another with respect to the short transverse axis of the elongated basic shape.
- the direction of movement of the pump elements runs perpendicular to a horizontal cross-sectional plane.
- the central axes M of the pump elements extending in the direction of the movement of the actuating device are on one Long axis, which runs in the horizontal cross-sectional plane transverse to the transverse axis Q.
- the width of the dispenser 1 and in particular of the pump head 3 in the direction of the transverse axis Q is smaller than in the direction of the long axis L connecting the pump organs.
- the width of the dispenser in the direction of the transverse axis Q and the long axis L be the same size ..
- an actuating section 51 is provided on a narrow side of the pump head 3, the applicator 61 with the outlet openings 63a, 63b being arranged on the opposite narrow side of the pump head 3. This arrangement enables the dispenser to be gripped and actuated more conveniently than dispensers in which the actuation section and the applicator are each attached to the broad side of a pump head.
- the distribution piece 60 is provided on edge sections 64 on its broad sides with feather-like projections 65 which point in the direction of the head piece 90 and which protrude under a bell-like section of the distribution piece 60 pointing towards the adapter 70 .
- Their main direction of extension runs parallel to the central salmon M of the pump organs.
- the feather-like projections 65 overlap the bell-like section of the distribution piece 60 and also project in the transverse direction on the outside thereof.
- the upper end 66 of the parallel key-like projections 65 facing the key 50 is curved to form part of a pivot bearing for the key 50.
- Each fit-like projection 65 is slidably received in a groove 95 provided on the head piece 90, which runs parallel to the central axes M of the pump elements on the inside of the outer edge 92 of the head piece 90.
- the sides of the feather-like projections 65 pointing in the direction of the long axis L are on the side walls of the respective grooves 95. supported.
- the feather-like projections 65 are each provided with a shoulder 69 in the direction of the transverse axis Q, which, as shown in FIG. 2, bears against the projections 99 provided in the grooves 95 in the upper position of the pistons 80 by a further upward movement of the actuating device 4 to prevent beyond the top position.
- the actuating device 4 since, in the dispenser 1 according to the invention, even in the uppermost position, the actuating device 4 has a relatively long guide length via the feather-like projection 65, a reduction in the volume of the pumping chambers in one is already when the actuating device 4 begins to be depressed very precisely defined relationship to one another is possible, so that a predetermined mixing ratio of the components from the different storage chambers 21 can be maintained with great accuracy. Even in the fully depressed position of the actuating device 4, each key-like projection 65 is in engagement with the corresponding groove 95.
- the mixing ratio of the components is maintained over the entire stroke of the actuating device 4, so that with appropriate dimensioning of the storage chamber 21 in the same ratio to the ratio of the displacement volume of the pumping chambers, simultaneous complete emptying of the storage chambers 21 can be achieved and not in one of the Chambers remains due to metering inaccuracies due to the inclination of the actuating device 4. Due to the relatively high stiffness of the pump elements of the straight movement of the pistons 80, the displacement volume of the pump elements can be easily and precisely coordinated in advance. Differences in viscosity of the individual media are therefore negligible when setting an exact mixing ratio.
- a dispenser is shown in which the pump elements and associated storage chambers 21 are arranged next to one another in mirror symmetry with respect to the transverse axis Q. This results in a mixing ratio of 1: 1 for the dispenser according to FIG. 1. If other mixing ratios are desired, the displacement volumes and the storage chamber mern 21 in this relationship to each other, deviating from a symmetrical design.
- the straight guides arranged essentially vertically on the short transverse axis Q lead to increased rigidity of the actuating device 4.
- FIG. 1 there is also an additional straight line at the intersection of the transverse axis Q and the long axis L. 3 in parallel alignment with the central axes M, which is shown by a hollow cylinder-like protrusion 96 of the head piece 90 shown in FIG. 3 and a hollow cylinder section 76 correspondingly adapted in its inner diameter and protruding from the adapter 70 in the direction of the head piece 90 is formed.
- this cylinder arrangement can serve as a guide and centering for the return spring 120.
- grooves or perforations can be provided on the bulge 96 and / or the hollow cylinder section 76.
- the actuating member 4 is formed by several components for manufacturing reasons.
- the feather-like projections 65 are provided on the distributor 60.
- the distribution piece 60 is secured by means of the shoulders 69 and the projections 99 on the head piece 90 against lifting off from the adapter 70.
- the tongue-and-groove straight guides can also be attached to the adapter 70 itself.
- parts of the adapter 70 and the distribution piece 60 can be formed in one piece with one another.
- the distribution piece 60 is fastened to the adapter 70 via its bell-like section.
- the outflow channels 62a, 62b run from the first non-return devices 130 through the adapter 70 and the distributor 60 to the outlet openings 63a, 63b provided at an end of the applicator 61 which points obliquely upwards.
- the outflow channels 62a, 62b are arranged concentrically to one another in the region of the outlet openings 63a, 63b. This makes it possible, given a corresponding viscosity of the components, to sheath a strand of a first component with a second one, for example in order to protect the component lying in the center of the mixture strand from premature reaction with the environment.
- the separate guidance of the individual components as far as the outlet openings 63a, 63b also enables an exact mixing ratio to be maintained when dispensing.
- the volumes of the outflow channels 62a, 62b are preferably dimensioned the same, so that the fronts of the media to be dispensed arrive at the outlet openings at the same time when dispensing for the first time.
- the orientation of the applicator 61 has a directional component pointing away from the base of the dispenser 1. This orientation of the applicator 61 also has the advantage over the essentially horizontally oriented outlet openings that the dispenser is easier to handle and better prevents a user's hand from being wetted with medium.
- a key 50 is pivotably mounted via a V-shaped recess 53.
- the key 50 has a bell-like basic shape, from which a channel-like section protrudes in accordance with the inclination of the applicator 61, at the upper end of which a shear section 52 is provided.
- this shear section 52 closes the outlet openings 63a, 63b of the applicator 61. lying on the narrow side, the button 50 has an actuating section 51 which extends essentially horizontally.
- the button 50 pivots about the pivot bearings formed by the V-shaped recesses 53 and the upper ends 66 of the distributor 60 until a stop, in the first exemplary embodiment the outer wall of the pump cylinder 91 protruding from the head piece 90, is one Movement limited.
- the outlet openings 63a, 63b of the applicator 61 are released at the same time.
- 100 engagement projections are provided on it and on the apron.
- the apron 100 is pulled up and provided with articulation projections 104, against the underside of which faces the bottom side, contact portions 54 of the key 50 each.
- FIG. 6 A second embodiment of the invention is shown in FIG. 6.
- 4 sealing sleeves 110 are provided between the pump cylinder 91 and the actuating device.
- the sealing sleeves 110 reliably prevent a reaction due to any leakage of media escaping from the pumping chambers in the space between the head piece 90 and the actuating device 4, which could lead to a blockage of the pump head 3, in particular in the case of hardening mixtures.
- a certain amount of distortion or misalignment between the pump cylinders 91 and the pistons 80 connected to the adapter 70 or distributor 60 can also be compensated for.
- FIG. 6 In the second exemplary embodiment shown in FIG.
- the sealing sleeves 110 are designed as essentially rotationally symmetrical, flexible bodies which are attached between the edge 93 of the respective pump cylinder 91 in the direction of the actuating device and the adapter 70. With appropriate dimensioning and material selection, the sealing sleeves 110 can simultaneously take over the function of the return spring 120. If a return spring 120 made of metal is dispensed with, then all components can be made from recyclable plastic, in particular as plastic injection molded parts, so that dismantling is not necessary when the pump head 3 is recycled.
- each check valve 150 shown in FIG. 6 has a spring section 151 facing the storage device 2, which is supported against the side of the head piece 90 facing the storage device 2.
- the spring section 151 has a multiplicity of spring arms extending away from a central pin 152, between each of which clear areas are provided in order to allow medium to flow through.
- a sealing plate 153 Connected to the central pin 152 is a sealing plate 153 which, with its side pointing in the direction opposite to the conveying direction of the medium, bears against a valve seat on the head piece 90 and is prestressed against it by means of the spring section 151 due to the elasticity of the spring arms in order to ensure reliable sealing and to allow the valve 150 to close quickly and automatically upon completion of the movement of the piston 80.
- the central pin 152 and thus the sealing plate 153 are moved in the conveying direction of the medium, the tension in the spring section 151 increasing and when the piston movement ends, the sealing plate 153 is reset.
- the sealing plate 153 is designed as a separate part, which has a sleeve-like section 154 and is attached to the central pin 152, which is formed in one piece with the spring section 151, by means of a snap connection.
- the spring section 151 and the sealing plate 153 can be made of hard, resistant material in order to keep wear of the non-return device due to flow effects low in the case of aggressive media.
- the check valves described in connection with FIG. 6 can also be used in other ways as check valves.
