Abstract
The invention relates to dispensers for fluid products, particularly oral dosing of medicines. The dispenser is a pump dispenser and has a separate nozzle attachment. The nozzle and dispenser may be uncoupled in a holding position or coupled position. A child resistance feature is disclosed which prevents unauthorized coupling of the dispenser and nozzle, thereby preventing unauthorized dispensing of product. The child resistance feature only allows coupling of the dispenser and nozzle when a coupling control element is triggered and then maintains this coupling with additional features. A protective cover for the dispenser is also disclosed, which covers the nozzle attachment and pump plunger button.

A dispenser for fluid product, the dispenser comprising:
- a dispenser body, the dispenser body comprising a discharge outlet defining an outlet opening and an outlet closure valve with a closure mechanism comprising a closure member which in a closed position closes the discharge outlet;
- an outlet attachment, the outlet attachment defining an outlet conduit having a nozzle opening, and which can be coupled to the dispenser at the discharge outlet by a coupling structure, the coupling structure comprising respective coupling elements of the dispenser body and outlet attachment which interfit, and so that in a coupled condition fluid product can be dispensed from the dispenser through the outlet attachment;
- said coupling structure providing that the coupling of the outlet attachment to the dispenser comprises a completion movement to reach said coupled condition in which fluid product can be dispensed from the dispenser through the outlet attachment;
- the dispenser comprising additionally a security mechanism, the security mechanism comprising respective cooperating elements of the dispenser body and outlet attachment, and the security mechanism being controllably adjustable between a blocking condition, in which said cooperating elements co-operate to block the completion movement, and an access condition in which said cooperating elements allow the completion movement.
