<p>The invention relates to an injection device that may be used with standard pharmaceutical vials, or other similar type of container, for the dispensing, or administration of the contents of the container without the use of a syringe. When assembled, the injection device includes a container (2) having a base and an open neck. An internal piston (10) is located within the container (2) and has an orifice (28). A needle (22) is releasably secured to the main body (14) of the internal piston (10) in fluid communication with the orifice (28). A plunger rod (26) is also releasably secured to the main body (14). Both the needle (22) and the plunger rod (26) extend in the same direction through the open neck of the container (2). Movement of the internal piston towards the base of the container (2) therefore forces that part of the contents of the container that is below the internal piston (10) through the orifice and out of the needle (22).</p>
