Abstract
An inner receptacle having a single integral piece flexible bag including a thin walled portion and a rigid fitment portion. The fitment portion includes a flange which is larger in diameter than the flexible bag to provide a mechanism to attach the inner receptacle to a bottle. The fitment portion also provides a finger grasping portion. The inner receptacle may be utilized in, for example, a squeeze pump package, a trigger or finger pump package, or a mechanical pump package. The inner receptacle also includes a mechanism for enabling substantially all of the product therein to be dispensed. One such mechanism is provided by a perforated diptube. Another such mechanism is provided by the combination of a resiliently deformable upper half and a collapsible lower half to cause the flexible bag to invert upon itself. These single integral piece flexible bags are preferably made by a modified pressblowing process wherein an increased range of motion is provided by a rack and pinion mechanism to enable formation of the large flange.
