Definitions

  • the invention relates to a child-resistant discharge device for media according to the preamble of claim 1.
  • the invention relates to a child-resistant discharge device which is intended to prevent children from coming into contact with the contents of a discharge device. Opening mechanisms are therefore provided that are not overcome by children. For some media, national and international laws even make mandatory the use of parental controls.
  • a discharge device for a medium which comprises a closure device for an exit region of a storage container for the medium.
  • the closure device has a sleeve-like closure part provided with an internal thread and can be screwed onto an external thread of the outlet region of the storage container designed as a neck.
  • the closure part is surrounded by a cap-like securing part. This is to prevent that can be done by simply unscrewing the VerMitffevotechnisch an unauthorized access to the contents of the storage container.
  • the disadvantage is that the locking of a manually operable pump part by means of the known spring bars is not sufficiently reliable.
  • the object of the invention is therefore to provide a child-resistant discharge device for media, in which the unauthorized access to the contents of the reservoir is improved.
  • a child-resistant discharge device in which the function of spring bars is combined with a rotary movement to move the discharge in and out of a blocking position.
  • Such a combined movement with a pressure and a rotational component causes a complex opening mechanism, which is considered to be child resistant.
  • the spring bars are inventively formed on a double spring.
  • the spring force of such a double spring is easily selectable, which can be influenced on the pressure force required to release the blocking position.
  • the discharge devices can be equipped individually and differently with double springs by the use of a spring insert. Because the double spring can be formed as a separate insert part, separate finger pads can also be formed. Customer wishes in the training of fingerpads can be considered. This applies in terms of size and the actuation force to release the child safety.
  • the double spring can be equipped with an integrated energy accumulator, which ensures that the inner tongues in the unloaded state of the double spring with a friction torque (braked) are slidably positioned against the inner wall. In the operating position and the blocking position it is ensured that the inner tongues move against the inner wall. The functions of the operation as well as the blocking are then ensured particularly secure.
  • the double spring can be inserted into a recessed area of a sleeve-type actuator and covered by an actuator cover. In this normal position, the double spring is preferably not or only minimally loaded. Guide elements may be provided for fixing the double spring to ensure their uniform operation on the spring bars. In a further development of the invention, a higher number than two spring bars may be provided.

  • the invention relates to a child-resistant discharge device for media with a reservoir 1 and a sealed to the reservoir 1 via a closure element 2 attached pump part 3 for conveying Medium from the reservoir 1.
  • an actuatable discharge section 4 On the pump part 3 is placed an actuatable discharge section 4, which is axially displaceably guided on a support member 5 associated with the closure element 2 for carrying out a lifting movement for dispensing medium.
  • the discharge section 4 is for actuating the pump part 3 by an actuation path a between a lower actuation position shown in FIG. 8, Fig.10 and an upper rest position shown in FIG. 5 in an actuating position 14 movable.
  • the discharge section 4 is rotatable relative to the carrier part 5 about a central axis X.
  • the discharge section 4 is preferably fixed to the carrier part 5 via a snap connection 6.
  • the carrier part 5 itself is fixed to the closure element 2 by a fastening device 7 (cf., Fig. 15), so that the carrier part 5 assumes a preferably fixed position relative to a container neck 8 of the storage container 1.
  • the carrier part 5 and the closure element 2 can also be formed in one piece.
  • the closure element 2 can be provided in a known manner with an internal thread which can be screwed onto an external thread 9 on the container neck 8.
  • a barbed toothing 10 can secure this screwing and prevent unscrewing.
  • Alternatives to the screw cap are, for example, crimp seals or snap closures.
  • the closure element 2 surrounds the container neck 8 preferably like a shell, whereby a withdrawal from the container neck 8 is difficult.
  • the shape of the discharge section 4 can be selected depending on the application. According to FIGS. 1 to 15, the discharge section 4 is formed like a nozzle with a nozzle 34 for a nasal application. For dispensing eye drops, the dispensing section 4 is preferably formed with a shorter neck 34 than shown.
  • the discharge section 4 by means of manually operable spring bars 11, 12 in at least one blocking position 13 on the support member 5 can be locked to unauthorized access to prevent the contents of the reservoir 1.
  • the discharge section 4 is not movable in the blocking position 13 into a lower actuation position in an actuation position 14. This is only possible if the spring webs 11, 12 are positioned in the actuation position 14 to the carrier part 5, as shown in FIG. 8 and FIG. 10 and as will be explained below.

  • the tongues 17 are each assigned to an inner wall 21 of the carrier part 5 a blocking position 13 which is limited by radial detents 19, 20 and can be moved in a rotational movement Z of the discharge section 4 (see FIG. Compression of the double spring 36 creates a clearance between the tongues 17 and the catches 19 for releasing the blocking position 13 and turning back (the rotational movement Z) of the discharge section 4 into the actuating position 14.
  • the inner tongues 17 on the inner wall 21 of the support part 5 are each assigned a guide ramp 18 as access curve to a footprint 22 of the blocking position 13.
  • This guide ramp 18 thus forms a sliding surface for each free end of the tongue 17, which guides the tongue 17 in the blocking position 13, when the discharge section 4 is in the upper rest position of the actuating position 14. If, on the other hand, the discharge section in the actuation position 14 is moved to a lower actuation position, as shown in FIG. 8, the guide ramp 18 prevents the discharge section 4 from rotating as a lateral stop into the blocking position 13 (see FIG. This is to ensure that a blocking of the discharge section 4 in order to prevent it from being actuated in the stroke direction of the center axis X should only take place when the discharge section 4 is in the upper rest position of the actuation position 14.
  • the two-armed compression springs 37, 38 are preferably designed as a same-armed, leaf-spring-like compression springs.

  • fixing elements may be provided for positioning the double spring 36 on the actuation plate 15, for example as webs 26, 28 and / or recesses 27 are formed to clamp a double spring 36 on the actuator divider 15.
  • the closure element 2 preferably has an axially extending, here the sleeve-like support member 5 penetrating dome 29, which engages in an axial guide track 30 of the discharge section 4 for axial support of the discharge section 4 on the closure element 2 in the lifting movement for stipulateaustrag and during rotation in the Blocking position 13.
  • the guide ramp 18 may define a distance in the circumferential direction of the preferably circular carrier part 5, which determines a twist angle of the discharge section 4 relative to the carrier part 5 in the blocking position 13.
  • the guide ramp 18 preferably further includes an end portion that extends into or over the footprint 22. This end portion thus forms a transfer section via the input-side notch 19.
  • the guide ramp 18 can thus optimize the movement of the respective tongue 17 into the blocking position 13 by selecting a distance from the inner wall 21, as FIG. 8 illustrates.
