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, b) a reservoir for the product, said reservoir being one of received in or formed by the housing, c) a drive member which executes a drive movement and has at least one engagement flank, d) an output member which executes an axial output movement to deliver product from the reservoir, and has at least one engagement flank in a flank engagement with the engagement flank of the drive member such that the drive movement of the drive member produces the output movement of the output member, and e) a device for reducing play which, in an adjustment engagement with the drive member and the output member, is displaced relative to the drive member and the output member into an adjustment position and is secured in the adjustment position such that an axial play of the flank engagement is reduced.

Abstract
A device for metered administration of a liquid product, including a housing, a reservoir for the product, the reservoir being received or formed by the housing, a drive member which executes a drive movement and has at least one engagement flank, an output member which executes an axial output movement to deliver product from the reservoir and has at least one engagement flank which is in a flank engagement with the engagement flank of the drive member such that the drive movement of the drive member produces the output movement of the output member, and a device for reducing play which, in an adjustment engagement with the drive member and the output member, is displaced relative to the drive member and the output member into an adjustment position and is secured in the adjustment position such that an axial play of the flank engagement is reduced.

22. A device for administering a substance in doses, comprising a housing, a reservoir for the product, a drive member which executes a drive movement and has at least one engagement flank, an output member which executes an axial output movement and has at least one engagement flank which is in a flank engagement with the engagement flank of the drive member such that the drive movement of the drive member produces the output movement of the output member, and a device for reducing play which is displaceable relative to the drive member and the output member into an adjustment position and is securable in the adjustment position such that an axial play of the flank engagement is reduced.
