Device for metered administration of a liquid product
First Claim
1. A device for metered administration of a liquid product, said device comprising:
- a) a housing which forms one of a product reservoir or a receiving seat for a product reservoir,b) a force sensor,c) a delivery means which executes an axial output movement in a delivery direction in order to deliver product from the product reservoir, and which is supported via the sensor on the housing counter to the delivery direction, andd) a contact element on which the sensor is axially supported, whereine) the contact element forms a device for reducing play which is axially movable in a threaded adjustment engagement with the housing from an initial position to an adjustment position in which an axial play between the delivery means and the housing is reduced, and whereby in the adjustment position the device for reducing play is secured against axial movement.

Abstract
A device for administering doses of a substance, the device including a housing forming one of a product reservoir or a receiving seat for a product reservoir, a force sensor, a delivery mechanism which executes an axial output movement in a delivery direction to deliver a dose from the product reservoir, and which is supported via the sensor on the housing counter to the delivery direction, and a contact element on which the sensor is axially supported, at least one of the contact element and sensor forming a device for reducing play which, in an adjustment engagement with at least one of the housing or the delivery mechanism, is displaced into an adjustment position and axially secured in the adjustment position in such a way that axial play between the delivery mechanism and the housing is reduced.

25. A device for metered administration of a liquid product, said device comprising:
-
a) a housing which forms one of a product reservoir or a receiving seat for a product reservoir, b) a force sensor, c) a delivery mechanism which executes an axial output movement in a delivery direction in order to deliver product from the product reservoir, and which is supported via the sensor on the housing counter to the delivery direction, and d) a contact element on which the sensor is axially supported counter to the delivery direction, the contact element comprising a cam protruding from a front face of the thereof in a delivery direction, the cam forming a contact point between the contact element and the force sensor, wherein e) the contact element forms a device for reducing play which is axially movable in a threaded adjustment engagement with the housing from an initial position to an adjustment position in which an axial play between the delivery mechanism and the housing is reduced, and whereby in the adjustment position the device for reducing play is secured against axial movement, the delivery mechanism is in abutment against the housing in the delivery direction, and the contact point is in abutment against a rear face of the force sensor. - View Dependent Claims (26, 27)
