DEVICE FOR THE DOSED ADMINISTRATION OF A FLUID PRODUCT, ADAPTED FOR THE REPLACEMENT OF A CONTAINER
First Claim
1. A device for administering a fluid product, comprising a first housing part, a second housing part detachably connectable to the first housing part, a piston rod held such that it can be displaced for an emptying movement, an actuatable drive element for the piston rod, a coupling element including a coupling input element that couples the drive element to the piston rod in a coupling engagement, transmits a driving force of the drive element to the piston rod, and triggers the emptying movement, and a decoupling element displaceably connected to the second housing part and coupled to the first housing part such that it is displaced, by a movement of the housing parts in relation to each other into a decoupling position wherein the piston rod is decoupled from the coupling input element.

Abstract
A device for administering a fluid product, the device including a first housing part provided with a receiver for the product, a second housing part detachably connectable to the first housing part, a piston rod held such that it can be displaced for the exertion of an emptying movement, an actuatable or releasable drive element for the piston rod, a coupling element including a coupling input element that couples the drive element to the piston rod in a coupling engagement, transmits a driving force of the drive element to the piston rod, and triggers the emptying movement, and a decoupling element displaceably connected to the second housing part and coupled to the first housing part such that it is displaced, by a movement of the housing parts in relation to each other when the housing parts are separated into a decoupling position wherein the piston rod is decoupled from the coupling input element.

2. A device for administering a fluid product, said device including:
-
a) a first casing part comprising a reservoir for the product; b) a second casing part detachably connected to the first casing part; c) a piston rod movably held for exerting a delivery movement from the second casing part; d) a drive member which can be operated for moving the piston rod; e) a coupler comprising a coupler input member which couples the drive member to the piston rod in a coupler engagement and transfers a drive force of the drive member onto the piston rod and causes the delivery movement; and f) a decoupling member movably connected to the second casing part and coupled to the first casing part such that it is moved into a decoupling position which decouples the piston rod from the coupler input member by a movement of the casing parts when the casing parts are moved relative to each other to be detached. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
