Definitions

  • the invention relates to a discharge device according to the preamble of claim 1.

  • a detection device available in the area or on the discharge device, with which any or such data can be recorded, stored and possibly displayed visibly from the outside, in connection with the Use of the medium are important.
  • data can include, for example, the number of applications that have already been completed and / or at least one subsequent application time or the like. his.
  • this detection element can be mounted on a base body, which at the same time serves to fasten the discharge pump to the media store.
  • the invention is also based on the object of providing a discharge device which is improved over known designs, in particular for certain applications, and which can preferably be designed and / or assembled in a very simple manner.
  • the features of claim 1 are suitable for solving.
  • the basic body of the detection device is formed by a separate component that can also be easily attached to the discharge unit when its discharge conveyor is not with a cap or screw cap, but with a simpler one, which can be fixed, for example, by deformation or can only be opened by destruction Attachment, as it can be formed by a Crimean ring, is attached to the media storage.
  • an axially and / or rotationally rigid holder is expediently provided, the base body being able to form a reinforcement of the relatively thin-walled fastening element for the connection of the discharge conveyor to the media store.
  • the base body form a cover for complete shielding of this fastening and, if necessary, the constricted neck of the vessel and connect it in an elastically resilient manner to a shoulder of the vessel belly of the media store essentially without gaps, so that there are practically no dirt gaps.
  • the outer width of the cover can be at most or be approximately as large as the outer width of the vessel belly, so that there is a relatively uniformly continuous outer surface.
  • the base body can be designed directly as a scale support for at least one scale, the scale symbols of which are expediently distributed substantially uniformly over the entire circumference. It is also conceivable to hold the base body relatively rotatably on the discharge unit so that it can be adjusted to different starting positions.
  • the base body advantageously has a detection and / or display element in the manner of a freewheel so that it is secured against unintentional rotation on the one hand and on the other hand can only be adjusted in one direction by applying a correspondingly high actuating force while it is in the opposite direction is positively locked. If this link is not formed by an actuating body which is only supported on the base body, but is mounted essentially independently of the base body in a separate bearing approximately axially and / or in a rotating manner, it can be formed in a simple manner by an actuating cap for actuating the discharge conveyor.
  • the base body can be assembled very easily by essentially linear attachment or resilient snap-on snapping. If the one of two mutually movable members of the detection device is formed by the actuating member of the discharge actuation, only a single additional component is required to arrange a counting device, namely the base body or scale carrier, which could possibly also surround the actuating member on the outer circumference and expedient in this case with a display window or the like. would be provided to identify the scale provided on the circumference of the actuator.
  • the memory suitably consists of glass.

  • 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 or a fastening 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 by the fastening 15 on one flank.
  • the part of the base body protruding from the storage vessel 4 and the fastening 15 are overlapped by a cap 19 which forms the actuating member 11 with its end face.

  • the cap 19 forms a display or detection element 22 which can be rotated relative to the base body 21, the pump 6 and the storage vessel 4 in each stroke position, and the jacket of the cap 19 as the actuating element assigned.
