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 glass container for the product,b) delivery means 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, andc) an inherently axially rigid housing support structure formed as a sleeve-shaped body which supports the container in and counter to the delivery direction, whereind) the housing support structure having, over the axial length of the container, an axial thermal expansion which, within a temperature range in which the device is used, differs by about 500% or less from the axial thermal expansion of the container.

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.

26. A device for administering a dose of a substance, the device comprising:
-
a container for the substance, the container having an axial length and an axial coefficient of thermal expansion, the container being formed from glass; a delivery mechanism which acts on the substance, and a support structure comprising a first support shoulder disposed proximate a distal end of the support structure projecting substantially transversely with respect to a delivery direction which supports the container in the delivery direction and a second support shoulder disposed proximate a proximal end of the support structure projecting substantially transversely with respect to the delivery direction which supports the container counter to the delivery direction, wherein the support structure further comprises a distal opening sized and shaped to accommodate passage of the container into a receiving compartment of the support structure and a closure element configured to close the distal opening, wherein the closure element forms the first support shoulder and is non-destructively releasably coupled to the device, and wherein the support structure is formed as a sleeve-shaped body and has, over the axial length of the container, an axial coefficient of thermal expansion which, within a temperature range in which the device is used, differs by about 500% or less from the axial thermal expansion of the container. - View Dependent Claims (27, 28, 29)
