Abstract
A liquid dispenser is for the delivery of pharmaceutical liquids, including a droplet dispenser, the liquid reservoir thereof being formed by a squeezable bottle body. Two measures secure the liquid dispenser, namely the provision of a cover body, an application of force on the squeezable bottle body being able to be prevented thereby, as well as a cap with a rotatable locking ring. The removal of the cap and the transfer of the cover body into a use position requires the deformation of an annular partial element.
Claims28
A liquid dispenser for discharge of pharmaceutical liquids, the liquid dispenser comprising:
- a squeezable bottle body having a container neck;
- a delivery head fastened to the squeezable bottle body, the delivery head having a delivery opening through which delivery opening liquid is delivered from the squeezable bottle body;
- and
- a first cover body having at least one locking wall and defining at least one actuating recess,
- the first cover body being provided so as to be captive and movable on the liquid dispenser, wherein
- in a locked position the first cover body covers a partial region of the squeezable bottle body via the at least one locking wall, such that a compression of the squeezable bottle body is prevented or at least impeded, and in an open position the first cover body opens the partial region of the squeezable bottle body via the at least one actuating recess such that a compression of the squeezable bottle body is possible.
A liquid dispenser for discharge of pharmaceutical liquids, the liquid dispenser comprising:
- a delivery device having a liquid reservoir and a delivery head with a delivery opening;
- and
- a replaceable cap, the cap in a positioned state covering the delivery opening and in a removed state opening the delivery opening for delivery of liquid,
- the cap having a cap body and a locking ring attached to the cap body for rotatable movement relative to the cap body;
- wherein the delivery device and the locking ring include respective locking profiles facing one another in the positioned state, said locking profiles preventing a removal of the cap in at least one securing-rotational position of the locking ring relative to the delivery device by a positive connection, and
- the locking profiles are configured such that a removal of the cap is only possible when the locking ring has been rotated relative to the delivery device into an opening-rotational position.
