A syringe for containing and dispensing a fluid material, the syringe comprising: a barrel configured for containing a fluid material, the barrel including an inlet end and an outlet end, wherein the outlet end includes a tapered portion having an inner surface that defines a tapered void, and wherein at least one barrel opening is formed in a sidewall of the tapered portion of the barrel through which the fluid material can flow; a plunger including: a stem extending from a first end that is disposed within the barrel to a second end that is disposed outside of the barrel, wherein the first end of the stem is configured in size and shape to enter the tapered portion of the barrel and to substantially conformingly engage the inner surface of the tapered portion of the barrel; and sealing means for creating a seal that extends circumferentially about the plunger between the stem and the barrel, wherein the sealing means is disposed on the stem proximate the first end of the stem; and a valve that is disposed in rotational alignment with the barrel and in abutting engagement with the tapered portion of the barrel, such that the valve controls passage of the fluid material from the at least one barrel opening when the valve is rotated with respect to the barrel.
