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, and d) a contact element on which the sensor is axially supported, wherein e) at least one of contact element and sensor form a device for reducing play which, in an adjustment engagement with at least one of the housing or the delivery means, is displaced into an adjustment position and axially secured in the adjustment position whereby an axial play between the delivery means and the housing is reduced.
