Abstract

The present invention relates to a drug delivery device for dispensing of a dose of a medicinal product, comprising:
a housing having at least one housing component ( 100; 200; 300 ) a cartridge comprising the medicinal product, a dose dispensing mechanism operably engaged with the cartridge for setting and/or dispensing of a predefined dose of the medicinal product, and a display element ( 102; 202; 302 ) being movably disposed relative to the at least one housing component ( 100; 200; 300 ), wherein

the display element ( 102; 202; 302 ) and the housing component ( 100; 200; 300 ) are mutually moveable for selectively concealing and/or revealing information provided on the display element ( 102; 202; 302 ).

First claim

The invention claimed is:

1. An injection drug delivery device for dispensing of a dose of a medicinal product, comprising:
a housing having at least one housing component,
a holder for a cartridge, the cartridge comprising the medicinal product,
a dose dispensing mechanism operably engaged with the cartridge for setting and/or dispensing of a predefined dose of the medicinal product, wherein the housing component serves as a housing for the dose dispensing mechanism, and
a spring biased display element movably disposed inside the at least one housing component,
an inner sleeve coupled to a helical spring and rotatably mounted in the housing component,
wherein the display element comprises a fixing element,
wherein the inner sleeve comprises a longitudinal slit adapted to receive the fixing element of the display element, and wherein the fixing element is larger in size than the longitudinal slit,
wherein the display element is moveable for selectively concealing and/or revealing information provided on the display element as the display element is moved into and out of the housing component,
wherein the display is rolled up on the inner sleeve, and wherein the inner sleeve is configured to surround at least a portion of the dose dispensing mechanism.

2. The drug delivery device according to claim 1 , wherein the housing component comprises a substantially sleeve-like geometry and wherein the display is movable in direction substantially perpendicular or parallel to the sleeve's long axis for revealing the information.

3. The drug delivery device according to claim 1 , wherein the housing component comprises a longitudinal slit intersected by at least a free end section of the display.

4. The drug delivery device according to claim 1 , wherein the display comprises a gripping element at its free end section.

5. The drug delivery device according to claim 1 , wherein the display comprises a lid at its free end section to cover a receptacle or slit of the housing component.

6. The drug delivery device according to claim 1 , wherein the display comprises information at its outer surface and has a smaller transverse diameter than the housing component, which is adapted to receive the display.

7. The drug delivery device according to claim 1 , wherein the display and the housing component comprise at least one longitudinal rib to be engaged with a corresponding longitudinal slit or notch.

8. The drug delivery device according to claim 1 ,
wherein the display and/or the housing component are transferable in an information revealing configuration against a spring force provided by at least one spring element.

9. The drug delivery device according to claim 1 , wherein the display is printed with printed information.

10. An injection drug delivery device for dispensing of a dose of a medicinal product, comprising:
a housing having at least one housing component,
a holder for a cartridge, the cartridge comprising the medicinal product,
a dose dispensing mechanism operably engaged with the cartridge for setting and/or dispensing of a predefined dose of the medicinal product, wherein the housing component serves as a housing for the dose dispensing mechanism, and
a display element movably disposed inside the at least one housing component, wherein the housing component and the display element comprise corresponding sleeve-like geometries and are slidably disposed with respect to each other along a long axis of the at least one housing component,
wherein the display element and the housing component are moveable with respect to one another for selectively concealing and/or revealing information provided on the display element as the display element is slid into and out of the housing component.

11. The drug delivery device according to claim 10 , wherein the housing component and the display comprise corresponding sleeve-like geometries and are slidably disposed with respect to each other along the sleeve's long axis.
