Container for storing a product to be injected, and an injection device for use with the container
First Claim
1. A container for a substance to be dispensed, the container comprisinga container body having one of a lateral wall or lateral walls and a piston in the container body, the lateral wall or lateral walls and the piston at least partially defining a chamber within the container body for accommodating a substance, the piston having a position that determines a maximum volume of the chamber and being moveable to another position to dispense the substance,wherein a ratio of a maximum height of the chamber to a maximum distance between the lateral wall or walls of the container body is approximately 1.25 to 1.0.

Abstract
A container for storing a product to be injected, e.g., a therapeutic or diagnostic liquid, wherein the container includes a container body and a piston body arranged in the container body in a sliding manner, the piston body moveable between a rear end position that determines a maximum filling of the container and a front end position to dispense the product, and wherein the container has a maximum opening ratio H/L of approximately 1.25 to 1.0, H corresponding to the maximum height of the container body and L corresponding to the maximum distance between the lateral wall or walls of the container body.

5. An injection device for dosed administration of a substance, comprising:
-
a container comprising a container body having one of a lateral wall or lateral walls and a piston in the container body, the lateral wall or lateral walls and the piston at least partially defining a chamber within the container body for accommodating a substance, the piston sealingly abutting the lateral wall or the lateral walls and having a position that determines a maximum volume of the chamber and being moveable to another position to dispense the substance, wherein a ratio of a maximum height of the chamber to a maximum distance between the lateral wall or walls of the container body is less than approximately 1.25; and a displacement mechanism for moving the piston in the container to cause an administration of the substance.

6. A container for storing a product to be injected, for example a therapeutic or diagnostic liquid, said container comprising:
-
a container body comprising side walls; and a piston body arranged in the container body in a sliding manner, wherein the side walls and the piston body at least partially define a chamber within the container body for storing the product, wherein to dispense the product, the piston body is displaced between a rear end position which determines a maximum volume of the chamber and a front end position;
whereinan opening ratio of a maximum height of the chamber to a maximum distance between the side walls is at most approximately 1.25; and
whereinan inner surface of the side walls is provided with a coating to reduce a frictional force between the container body and the piston body. - View Dependent Claims (7, 8, 9)

10. A container for storing a product to be injected, in particular a therapeutic or diagnostic liquid, comprising:
-
a container body comprising side walls; and a piston body arranged in the container body in a sliding manner, wherein the side walls and the piston body at least partially define a chamber within the container body for storing the product, wherein to dispense the product, can be the piston body is displaced between a rear end position which determines a maximum volume of the chamber filling and a front end position;
whereinthe container body is designed such that, with a kinetic friction of 20N between the container body and the piston body, an underpressure required for displacement of the piston body is at most approximately 0.2 bar. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
