Abstract
An aperture forming structure for a sealed containment and dispensing package for flowable products is provided. The structure includes a breakaway tip member of thermoformable plastic. In one embodiment a cap may be integrally formed with the aperture forming structure and may be used to protect the tip member or for reclosing the aperture. An alternative embodiment relates to a pouch, wherein a flap member portion of the pouch is folded over and sealingly attached to the body of the pouch. When the flap member portion is pulled away from the body, an outlet aperture is produced through the surface of the pouch.
