A drink straw container includes a hollow, elongated body that has a first end, a second end, an inner wall and an outer wall. The body has a frangible seal at the first end and a one-way valve located adjacent the second end that permits passage of fluids only from the second end toward the first end. The elongated body securely encloses a predetermined quantity of a consumable liquid. The inner and outer walls extend below the one-way valve to protect the valve from contacting a container surface. The lower end of the body may have a sealing membrane and a sliding puncture device to pierce the membrane. The straw may have an inner tube with a series of penetrating apertures for combining the consumable liquid with a mixing beverage. The straw may have a manually operated valve and a diameter reducing choke at the lower end of the straw.
