Definitions

  • the invention relates to a discharge device for media, which is provided with a discharge actuation for carrying out one or more discharge processes.
  • At least one detection device is expediently provided, which is preferably not arranged separately from the discharge device, but directly on it, but also one of the Discharge device and its attachment can form the assembly used.
  • the data to be recorded can be, for example, the number of applications that have taken place, the next application date and / or other data that can be identified via one or more synchronously or separately switched displays.
  • the respective detection device is switched on manually with an actuating element via an actuating drive, the actuating element being provided separately from the discharge actuation and / or being formed by the actuating element with which the medium is applied by manual pressure or the like.
  • the actuating element being provided separately from the discharge actuation and / or being formed by the actuating element with which the medium is applied by manual pressure or the like.
  • This can e.g. can be achieved in that strip or web-shaped adjusting cams inside or on the inner circumference of an actuating cap in and out of engagement with counter teeth or web-shaped counter-cams on one end face or on the outer circumference of a rotatably mounted detection element, which then by one each actuation stroke Cam division is rotated further.
  • the actuating drive can be completely disengaged, so that the detection element can only be secured with respect to the actuating element by friction, latching or the like. This can be undesirable if a rotatable part of the detection device is normally exposed and could thereby be inadvertently adjusted.
  • the invention is furthermore based on the object of providing a discharge device of the type mentioned, in which disadvantages of the known or described designs are avoided and which, in particular, ensure a security against inadvertent adjustment of the detection device.
  • the actuators of the actuator are expediently in direct engagement with one another in any position or at least in the release position.
  • the two actuators block one another in one, several or all release positions against actuating movements, but not against actuating movements.
  • control link or cam track makes it possible to provide contiguous individual curves for one discharge process each and to form such individual curves as desired in different ways.
  • discharge processes with different characteristics can be provided, which are inevitably actuated in succession because the cam can only be moved continuously in one direction by the actuating cam.
  • neighboring individual curves can determine different actuation strokes and the metering quantities to be applied and / or they can effect different sized steps of the actuators against each other.
  • Such a design is also suitable for discharge devices in which the actuator is not used for recording discharge processes.
  • the cam track also makes it possible to limit the actuating cam on at least one individual curve in the release position by means of a stop and / or on at least one individual curve with respect to movements beyond this release position.
  • the same can also be provided with regard to the actuation end position or for movements beyond this. Released positions and mutually offset actuation end positions are thus conceivable.
  • a resetting spring is expediently provided for this resetting, which is expediently formed by a resetting spring for a pump piston of the discharge device located within a pump cylinder, so that no separate spring is required for the actuators.
  • a structurally particularly simple and safe working design results if one of the actuators is formed directly by an actuating cap provided with a discharge nozzle or the like and the other actuator is formed by a cap-shaped or similar fastening element for fastening a discharge pump on a bottle neck, which on the outer circumference of the actuating cap is covered closely surrounded.
  • These two components are already present or indispensable in many discharge devices, so that no additional component is required to provide a detection device.
  • the actuating cap is in constant engagement with the fastening member via at least one actuating cam and at least one cam track, so that rotary movements of the actuating cap corresponding to the curve are only possible simultaneously with lifting movements.
  • the fastening member could also be formed in one piece with a cylinder housing of the discharge pump or with its end cover and / or with the seal for sealing against the bottle neck, so that there is a further structural simplification.
  • cam track also makes it possible, at the end of a certain number of discharge processes, to provide a release position which is blocked by a stop and which is closer to the actuation end position than the usual release positions.
  • This position can be with a ventilation position coincide, in which the inside of the bottle is vented through the discharge pump because an aeration valve formed by the pump is open.
  • this position can also coincide with an open position for an outlet valve which connects the pump chamber to an outlet channel and is opened by a stop. In any case, further use of the discharge device is excluded in this end position.
  • the discharge device 1 has a discharge unit 2 designed as a closed assembly assembly with a discharge pump or a discharge conveyor 3 and can be fastened as a whole to a storage vessel by a snap connection, a crimp ring, a screw connection or the like. It forms a discharge actuation 5 for the manual discharge of a metered discharge quantity. It is done by a Pump stroke actuates the piston unit 7 of a pump 6, which largely engages in the storage vessel 4, the pump chamber of which has a valve-controlled inlet 8 and a valve-controlled outlet 9.
  • the conveying handle forms an actuating member 11 or a pressure surface on an end face, which surrounds a piston or actuating plunger 10, which is preassembled with the piston unit 7 via a plug connection and is a component of the conveying handle.
  • the actuating plunger 10 is penetrated by an outlet channel 13 connected to the outlet 9 and surrounded by a discharge nozzle 12 which projects freely above the actuating member 11 and which has the outlet opening of the discharge unit 2 in the region of its free end.
  • the cylinder housing or a piston cover penetrated by the actuating plunger 10 forms a support body 14 with which the discharge conveyor 3 is fastened to the vessel neck 17 by a fastening member 15, for example a screw cap, which forms a corresponding vessel flange 16.
  • the part of the supporting body 14 protruding from the storage vessel 2 and the fastening member 15 are overlapped at least over part of their length by a cap 19, the end wall of which forms the conveying handle 11.
  • a detection device 20 is provided for the inevitable detection of each actuation stroke.
  • This has an essentially detachable, essentially sleeve-shaped and a one-piece assembly component with the fastening member 15, which is easily removable from the discharge conveyor 3, and a sleeve-shaped detection member 22 which surrounds the base body 21 in an axially displaceable and rotatable manner and through the jacket 35 of the cap 19 is formed.
  • the base body 21 adjoins the fastening member 15 in the region of a radially inward projecting clamping flange 26, essentially surrounds the support body 14 and stands freely against the inside of the End wall of the cap 19 in front.
  • the fastening member 15 can extend approximately to the transition of the vessel neck 17 into the enlarged vessel belly 18 and thereby form a casing 41 for completely covering the vessel 4 up to this area.
  • the actuating member 23 is formed by the same pressure surface as the actuating member 11 and has two engagement surfaces for the fingers of the user lying on both sides of the discharge nozzle 12.
  • the outer circumference of the jacket 28 of the fastening member 15 is continuous over approximately its entire length and over the length of the base body 21, so that it forms a good guide for the cap 19.
  • the cap 19 and the base body 21 engage with one another via an actuator 30, which inevitably causes a gradual rotary movement of the cap 19 relative to the base body 21 with each actuation stroke, in such a way that the direction of rotation inevitably always remains the same.
  • a longitudinal section of the jacket 35 of the cap 19 lying between its ends forms a sleeve-shaped actuator 43 and the fastening member 15 with its end section forming the base body 21 forms a sleeve-shaped actuator 45.
  • the actuator 43 On the cylindrical inner circumference, the actuator 43 has two diametrically opposed, radial provided inwardly projecting, cylindrical adjusting cams 33, each of which engage in a cam track 34, which extends approximately over half the circumference of the actuator 45.
  • the adjusting cams 33 also engage in the starting or release position shown in FIG. 1 in the associated cam track 34 in such a way that the cap 19, which is detachable per se from the piston unit 7, is positively secured against removal from the discharge conveyor 3.
  • a display device 37 which has a display window 38 in the end of the jacket 35 remote from the actuating members 11, 23 and a display window 38 as a breakthrough and a scale 40 with a uniform circumference on the outer circumference of the fastening member 15 distributed symbols, which is at least in the release position in the area of the display window 38.
  • the scale 40 is located on one side of the clamping flange 26 and the actuator 45 with the cam tracks 34 is essentially on the other side thereof, the actuator 45 being essentially formed by a sleeve 47 projecting freely over the clamping flange 26.
  • the display device 37 and the actuator 30 are axially close to each other.
  • the outer diameter of the scale 40 is substantially the same as the outer diameter of the actuator 45 and the inner diameter of the sensing element 22 is substantially the same as that of the actuator 43, the outer peripheral surface of the base body 21 between the scale 40 and the actuator 45 and the inner peripheral surface between the sensing element 22 and the actuator 43 goes through essentially continuously without paragraphs.
  • the detection element 22 and the actuator 43 can be plugged onto the base body 21 with the cap 19 from the free end of the actuator 45 and can thus be installed in a simple manner. If the discharge conveyor 3 is previously mounted on the base body 21 by inserting it, it is connected to the discharge nozzle 12 by a plug-in connection during the assembly of the cap 19. If the discharge conveyor 3 is then mounted, it is simultaneously connected to the base body 21 and the cap 19 by plug connections. In this respect, the cap 19 can form a preassembled structural unit with the base body 21.
  • the cam track 34 is formed by a meandering groove running in alternating directions, the width of which is essentially adapted to the diameter of the adjusting cam 33, but the adjoining sections merge into one another at acute and obtuse angles and not at right angles.
  • the cam track 34 forms a single cam 49 for each switching step, a plurality of e.g. twenty-one individual curves 49 lie between a backdrop entrance 53 at the beginning of the curved path 34 and a backdrop end 56.
  • the cam groove penetrates the free end face of the actuator 45, so that the actuating cam 33 can be inserted into the cam track 34 during assembly.
  • the course of the cam track is such that the actuating cam 33 is inevitably rotated by a partial step in the intended direction of rotation during the actuation stroke and is inevitably rotated further in the same direction during the return stroke.
  • the groove flanks form corresponding guide members 50, 54 for the actuating cam 39 in the area of the reversals 52 of the cam groove Setting cam 33 is applied under the force of the return spring of the discharge conveyor 3.
  • the cap 19 is thereby positively secured against being pulled off.
  • the distance between adjacent locking stops 55 corresponds to a switching step of the actuator 30 or the effective extension of a single curve 49.
  • the gate end 56 which is distant from the gate entrance, is axially offset relative to the locking stops 55 in such a way that the discharge conveyor 3 or the actuator 30 cannot return to its starting position as far as the locking stops 55 enable. At the end of the use of the discharge device 1, these components are thereby held in an actuating position which acts like an easily recognizable indicator that the discharge device is no longer available for use.
  • the link end 56 thus forms a lock 29 that can practically no longer be overcome.
  • the cam track 34 is formed in connection with the gate input 53 so that a complete pumping stroke must be carried out to transfer the actuating cam 33 to the first actuating stop 55, through which the pump chamber is emptied of air and possibly filled with medium from the storage vessel 4 by suction becomes.
  • the actuators for the discharge and the data acquisition can also be actuated separately, e.g. if the detection device should be operated independently of the discharge operation. Furthermore, two or more detection devices or actuators which can be operated inevitably jointly or independently of one another can be provided for one or more discharge conveyors 3 of the discharge device 1.
