1. An assembly for a drug delivery device comprising a housing having a right side member and a left side member;a dispensing container mounted within the housing and configured for holding a single dose of a fluid drug product;a reservoir container having a first outlet, mounted within the housing and holding a plurality of doses of the fluid drug product, wherein the dispensing container and the reservoir container are connected to one another, are in fluid communication and are both completely contained between the right side member and the left side member of the housing; andan actuator movably positioned between the dispensing container and the reservoir container and completely contained within the housing and configured to apply a squeezing force to the dispensing container for dispensing the single dose of the fluid drug product from the dispensing container through a second outlet, where the actuator moves relative to the housing during dispensing,wherein the dispensing container is refillable with doses of the fluid drug product from the reservoir container through a first one way check valve in fluid communication with the dispensing container that prevents fluid movement from the dispensing container into the reservoir container. 2. An assembly for a drug delivery device according to claim 1, wherein a tube connects an inlet of the dispensing container with the first outlet which is located at the reservoir container. 3. An assembly for a drug delivery device according to claim 1, wherein a second one way check valve is located in a dispensing flow path of the second outlet which is located at the dispensing container. 4. An assembly for a drug delivery device according to claim 3, wherein the second one way check valve prevents intaking of air or fluid or tissue into the dispensing container via the dispensing flow path. 5. An assembly for a drug delivery device according to claim 3 wherein the second one way check valve allows the fluid drug product to be dispensed through the second outlet which is located at the dispensing container. 6. An assembly for a drug delivery device according to claim 1, wherein the dispensing container comprises a hollow body. 7. An assembly for a drug delivery device according to claim 1, wherein the dispensing container is elastically deformable for dispensing a dose of the fluid drug product. 8. An assembly for a drug delivery device according to claim 1, wherein the actuator is located at the dispensing container for dispensing the fluid drug product. 9. An assembly for a drug delivery device according to claim 1, wherein the dispensing container is expanding after dispensing the fluid drug product and is, by means of a depression created in the dispensing container able to intake fluid drug product from the reservoir container.
