Abstract
A device for metered administration of a liquid product including a container for the product, a delivery mechanism which acts on the product located in the container and delivers product from the container by means of an axial output movement in a delivery direction, and an inherently axially rigid housing support structure which supports the container in and counter to the delivery direction, wherein the housing support structure has, over the axial length of the container, an axial thermal expansion coefficient which, within a temperature range in which the device is used, corresponds at least substantially to the axial thermal expansion coefficient of the container.
