Definitions

  • the invention relates to a dispenser for dispensing pharmaceutical liquids.
  • dispensers usually have a housing with integrated or attached liquid storage, a movable relative to the housing operating unit with finger support surface which is subjected to force for the purpose of actuation manually and is operatively connected to an outlet valve or a feed pump, and via a discharge opening through which the liquid can be discharged into a surrounding atmosphere.
  • the donors described herein may, in particular, be designed as nasal dispensers intended for nasal administration of medicaments.
  • the liquids to be dispensed with generic dispensers also include liquids whose ingestion may be detrimental if not medically indicated. It is particularly problematic when, for example, out of curiosity or while playing, children use pharmaceutical dispensers and in doing so carry out and ingest liquid. Depending on the fluid, this can be associated with significant risks to the health of a child.
  • the object of the invention is to further develop generic dispenser to the effect that with a low design effort an effective child safety is achieved.

  • the ratchet can prevent the discharge of liquid in various ways in its blocking rotational position.
  • a comparatively complex possibility is that by turning the ratchet wheel, not the mobility of the operating unit is mechanically prevented directly, but the possibility to discharge liquid by this movement. This could for example be done by decoupling the actuator from a conveyor such as a piston pump. It could also happen that a switchable valve is provided in the dispenser, which is switched by turning the ratchet wheel.
  • a switchable valve is provided in the dispenser, which is switched by turning the ratchet wheel.

  • Such a two-part cap with intended axial application of force is known, for example, from DE 102009049902 A1, the relevant disclosure of which is incorporated by reference in the present disclosure.
  • the inner cap of the protective cap can be unscrewed so far that it closes off the discharge opening movable with the actuating unit. When force applied to the cap thus no liquid can escape.
  • an inner end face of the inner cap abuts against the discharge opening in the fitted state of the inner cap and thereby closes it.

  • such a separate sealing element may be substantially planar, form said annular sealing surface or also form the extension on the inner end face of the inner cap.
  • the material of the sealing element is preferably of lower rigidity than the material of the inner cap, in order to apply sealingly in the region of the discharge opening or the nosepiece.
  • a dispenser according to the invention has a housing, a discharge opening and an actuating unit with a finger support surface displaceable in an axial direction relative to the housing for the purpose of discharging liquid.
  • the actuating unit is rotatable relative to the housing about an axis of rotation extending in the axial direction, wherein the actuating unit in at least one blocked blocking rotational position is not axially displaceable relative to the housing and in at least one unblocked actuation rotational position is axially displaceable relative to the housing.

This process is difficult for children to see through.

  • the locking device in such a manner that the unlocking can be achieved by applying force to at least one unlocking surface of the actuating unit itself. This is preferably done in that the application of force to the unlocking surface causes a radial displacement of a locking portion of the actuating unit, whereby it comes to unlocking.
  • the arrangement of the unlocking directly on the actuator unit has the consequence that the operation for an adult is hardly associated with additional effort and yet remains difficult to see through a child.
  • the unlocking surface is provided by its arrangement on the actuator unit, together with this Be actuation unit to be axially displaceable relative to the housing.

  • An advantage is the design in which is offset on the said jacket of the locking portion relative to the unlocking surface in the circumferential direction, in particular by 60 ° to 120 °. In this way, it can be achieved that a force application of the unlocking surface or the preferably two opposing unlocking surfaces causes a radially outward deflection of the at least one locking portion radially outward.

Abstract

L'invention concerne différentes variantes pour protéger des distributeurs connus pour la distribution de liquides pharmaceutiques contre l'utilisation par des enfants. Ces variantes comprennent une roue de blocage disposée de manière rotative sur le boîtier, qui empêche en particulier mécaniquement l'actionnement du distributeur, en outre des capuchons particuliers à l'épreuve des enfants qui ferment eux-mêmes directement l'ouverture de sortie ainsi que des verrouillages particuliers d'une unité d'actionnement pour empêcher l'aptitude à la rotation par rapport au boîtier nécessaire pour l'actionnement.
