Abstract

A reservoir and a plunger head contained within may be configured to move relative to each other in response to at least one of the reservoir being detached from a base, the base and/or the reservoir being removed from a packaging, and the base and/or the reservoir being moved relative to each other. A first layer may be configured to define a reservoir, the first layer, which may be made of a material compatible with fluidic media in the reservoir, may be adjacent a second layer for inhibiting a diffusion through the second layer. A first layer that may be less than 0.3 mm and made of a cyclic olefin copolymer may be configured to define a reservoir. A reservoir may be defined by a wall made of a cyclic olefin copolymer and the wall may be for substantially preventing light from passing through the reservoir.

at least one of the plunger head and the reservoir body configured to be rotatable relative to one another to reduce a retaining force between the plunger head and the reservoir body;

wherein at least one of the plunger head and the reservoir body is configured to be rotated relative to one another in response to at least one of detaching the reservoir body from the base, removing one of the base and the reservoir body from a packaging, and manually rotating one of the reservoir body and the base relative to the other.

3. The system of claim 1, wherein the reservoir body is pre-filled with fluidic media.

4. The system of claim 1, the reservoir body configured to be attachable to a fluid delivery device.

5. The system of claim 1, the system further comprising:

a casing configured to support the reservoir body.

6. The system of claim 5, the casing removably attachable to the base.

7. The system of claim 5,

the casing having one or more locking tabs for securing the casing to the base;

the base having one or more recesses for receiving the one or more of the locking tabs of the casing.

9. The system of claim 1, wherein the reservoir body is detached from the base before and while the plunger head is moved in the longitudinal direction relative to the reservoir body.

10. The system of claim 1, wherein the reservoir body is detachable from the base by rotating the reservoir body relative to the base.

11. The system of claim 10, wherein the plunger head is inhibited from rotating relative to the base when the reservoir body is rotated relative to the base.

12. The system of claim 10, wherein the plunger head is configured to be engaged with the base when the reservoir body is rotated relative to the base, to inhibit rotation of the plunger head relative to the base as the reservoir body is rotated relative to the base.
