Abstract:
A pre-filled disposable container has a rigid tubular body, a flexible bag positioned within the rigid tubular body, a cap, and a base sealing element. The rigid tubular body has an open-ended top and an open-ended bottom. The flexible bag has a top portion with a dispensing aperture, a bottom portion, and an outwardly extending annular flange. An annular retaining ring is adapted to lock the outwardly extending annular flange of the flexible bag against a top rim of the rigid tubular body. The cap is adapted to fit over the top portion of the flexible bag. A tear strip removably connects the cap and the annular retaining ring. The base sealing element is adapted to engage the open-ended bottom of the rigid tubular body to seal a vacuum aperture.
