Definitions

  • the invention relates to a discharge device according to the preamble of claim 1. It can be provided for media of any kind and is provided with a discharge actuation for carrying out a discharge process. This is advantageously designed so that it can be moved manually between a starting position and an end or actuation position in a movement cycle, e.g. is movable back and forth. In at least one position, the discharge actuation can expediently be fixed against movements in the actuation direction and / or reset direction with a lock at least within certain movement limits, the lock being intended to be released again or releasable by manual actuation.
  • This lock can e.g. as tamper protection or to prevent unauthorized or accidental use by children and is therefore particularly useful when pharmaceutical or cosmetic media are to be discharged.
  • EP-A-0 098 373 shows a cam which is radially releasable in an annular groove and which is moved axially relative to the annular groove during the pumping stroke.
  • US-A-4 368 830 shows a discharge device with a lock which engages during the actuating movement approximately when the actuating position is reached, so that the actuating member is locked in this actuating position. After disengaging the lock, the actuator must first make another movement or a return stroke to the starting position so that medium can be discharged.
  • the invention is also based on the object of providing a discharge device for media, by means of which disadvantages of known designs are avoided and which, in particular, ensures a high level of security that the lock is engaged.
  • a lock is designed to be self-engaging depending on at least one actuation movement. This means that it can e.g. after one of the several actuation cycles are automatically transferred into the locked position, so that a triggering must be carried out arbitrarily or deliberately in order to carry out a subsequent actuation cycle.
  • the blocking can take place in the starting position, actuating position and / or an intermediate position and it can act both against actuation and against resetting or only against one of these movements, several blocking positions of the same or different blocking effect being possible.
  • the lock works expediently with respect to the associated actuation direction of the discharge actuation, so that the lock can only be released by a movement deviating from the actuation movement for the discharge.
  • a trigger movement that is in the same direction at least one actuation movement would only be necessary for the triggering and only a subsequent actuation to carry out the discharge.
  • the same handle is provided, not for separate handling, both for actuating the discharge by opening a valve, actuating a pipette, a pump or the like, and for unlocking.
  • the handle can form separate actuators for the discharge and unlocking with a circumference and an end face and can be mounted both axially and rotatably approximately linearly.
  • a releasable pull-off protection can also be provided for a discharge and actuating head of the discharge device, so that it can be removed, but is positively secured against inadvertent removal, for example, in a storage state of the discharge device.
  • This pull-off protection is preferably formed by one of the locks or a lock that has the features mentioned.
  • a detection device which is advantageously arranged directly on the discharge device and is not formed by a spatially separate device.
  • data 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.
  • Movements of at least one detection device are expediently synchronized with changes in the state of the lock, for example a rotating change of position of the display with or without changing the display symbol and / or a transfer of the detection device into a standby position can be provided such that the detection device is switched on during the subsequent discharge process.
  • an actuating drive for actuating the detection device can be designed in a very simple manner and only have inclined cam surfaces which convert a stroke movement into a rotary movement.
  • a support or base body, which receives the associated locking elements of the lock and / or at least one detection element of the detection device, can be formed by a component which is to be fastened separately from a base body of the discharge conveyor, for example to a storage vessel for the medium.
  • a component which is to be fastened separately from a base body of the discharge conveyor for example to a storage vessel for the medium.
  • one and the same, already pre-assembled discharge unit can optionally be retrofitted with one of the mentioned designs, or this device can be exchanged for a different type.
  • different scales, different actuators or the like can be used. be provided.
  • cams of the lock and / or the detection device or an indicator, such as a display window are arranged on the discharge head and are formed in one piece therewith. The lock can simultaneously form a rotation lock against those forces that occur when the detection device is switched on.
  • the discharge device 1 has a discharge unit 2 designed as a self-contained assembly assembly with a discharge conveyor 3 and a storage vessel 4, which can be operated manually by a discharge actuation 5.
  • the piston unit 7 of a pump 6 engaging for the most part in the storage vessel 4 is actuated, the pump chamber of which has a valve-controlled inlet 8 and a valve-controlled outlet 9.

  • the cylinder housing forms a base body 14 with a cylinder cover, with which the discharge conveyor 3 is fastened to the vessel neck 17 by means of a fastening member 15, for example a crimp ring encompassing a cap-shaped vessel flange 16. Between this vessel flange 16 and the vessel belly 18, the vessel neck 17 forms an annular groove on the outer circumference, which can be delimited on one side by the fastening member 15.
  • the one protruding from the storage vessel 2 Part of the base body and the fastening member 15 are overlapped by a cap 19, which forms the conveying handle 11 with its end face.

  • the actuating cams 33 connect the jacket 35 in a rib-like manner and the sleeve 48 extending from the end wall of the cap 19, so that very high stability is ensured even with a thin-walled design.
  • the adjusting cams 33 lie completely outside of the grooves between the counter-cams 34.
  • the inclined surfaces of the cams run in pairs on one another, so that the detection member 22 is rotated, while the cap 19 is opposed to the base body 21 by the interlocking locking members of the lock 29 a reciprocating one during the pumping stroke and return stroke Performs rotary movement, but at the end of the return stroke takes almost the same rotational position with respect to the base body 21 as at the beginning of the pump stroke.
  • the actuating cams 33 form an actuator 43 which is integral with the handles, and the opposing cams 34 form an actuator 45 which is integral with the detection element 22.
  • the jacket 35 can be mounted relatively rotatably and rotatably on the outer circumference of the detection member 22 and the base body 21, so that only small bearing forces are transmitted to the bearing that is formed by the displaceable piston unit 7 and also carries the cap 19. After pulling off the cap 19, which is connected to the piston unit 7 via a plug-in connection, the detection element 22 or with this the base body 21 can be removed and replaced as an assembly.
  • the lock 29 and the actuator 30 are returned to the starting position by a return spring of the pump 6 provided in the discharge conveyor 3, so that no separate spring is required.
  • a display device 37 For externally recognizable display of the respective switching state of the detection device 20, a display device 37 is provided, which has a display window 38 in the rear end of the casing 35 as a breakthrough and in the starting position in the area on the outer circumference of the detection element 23 a scale 40 with symbols evenly distributed over the circumference having.
  • the scale 40 is provided immediately behind the actuator 45 at the rear end of the detection element 22 so that a symbol can be recognized by the display window 38 in each switching state.
  • the link 32 has on the outer circumference of the sleeve 47 a slot guide 49 which is open on this circumference and which, in view, is approximately ring-shaped around a link core 50 and has polygonally adjoining guide sections has, which are bounded on one side by the link core 50.
  • the locking cam 31 is located at the start of the link 51, which is followed by an approximately axial section of the link guide 49. This forms one of six angularly adjoining link sections, the locking cam 31 in the pump stroke end position lying in the transition between the second and the third link section, as can be seen from the positions indicated by dash-dotted lines in FIG. 2.
  • the locking cam 31 therefore does not return to the axial link section, but rather is laterally deflected by the link core 50.
  • the last link section opens with a transition transversely to the axial link section into the link start 51 and its flanks form locking stops 54, 55 for the locking cam 31 lying transversely to the stroke direction.
  • the locking cam 31 therefore lies immediately laterally adjacent between these locking stops 54, 55 to the start of the backdrop 51, so that axial movements of the cap 19 are positively locked in both opposite directions.
  • the cross-sectionally rectangular or square locking cam 31 is expediently arranged in a diamond shape such that it is guided or supported essentially only with corner edges in the first and fourth link sections and between the locking stops 54, 55, while it is supported in the second, third and fifth link sections can be performed substantially flat on the outer backdrop flank.

  • the actuating cams 33 come into engagement with the counter cams 34, while the locking cams 31 pass through the first link section, are then constantly engaged until shortly before the locking stops 54, 55 are reached so that there is a rotational connection between the cap 19 and the detection element 22 and come out of engagement again before reaching the locked position, so that the detection member 22 is held only by the friction connection 39.
  • the cap 19 with the detection member 22 executes a reciprocating rotary movement with respect to the base body 21.
  • the base body 21 can form a casing 41 which surrounds the storage vessel 4 approximately at its full height and which can extend approximately to or above the bottom of the storage vessel, so that the storage vessel 4 which is expediently made of glass is well protected against damage.
