Abstract
Embodiments relate to a film used to form a flexible bag including an inner sealant layer capable of providing a hermetic seal; an oxygen barrier layer capable of extending the shelf life of a food product; and an outer layer capable of providing abrasion and puncture resistance and tacking to the specialized tacky polymer strip mounted on the dispensing device.

30. A dispenser adapted to receive a flexible bag and dispense a product, the dispenser comprising:
-
a housing having a first wall and a second wall hingedly connected to the first wall and defining a chamber having a first end and a second end; a handle located proximate the chamber first end and having a trigger and a reversely biased actuating device; a segmented piston positioned in the chamber and actionably coupled to at least the handle; and an end cap adapted to be removably, rotatably received by the housing proximate the second end, the end cap defining at least one opening adapted to allow flow in only one direction, wherein the handle and segmented piston act in concert, such that upon completion of dispensing a predetermined amount of product, relieves any residual pressure on the flexible bag, preventing product weeping. - View Dependent Claims (31, 32, 33, 35, 36, 37, 38, 39, 40)

34. A method for dispensing a product using a dispenser adapted to receive a flexible bag comprising:
-
the dispenser comprising; a housing having a first wall and a second wall hingedly connected to the first wall and defining a chamber having a first end and a second end; a handle located proximate the chamber first end and having a trigger and a reversely biased actuating device; a segmented piston positioned in the chamber and actionably coupled to at least the handle; and an end cap adapted to be removably, rotatably received by the housing proximate the second end, the end cap defining at least one opening adapted to allow flow in only one direction; the flexible bag formed from a film comprising; at least one layer adapted to be folded upon itself without cracking, the at least one layer comprising; a first edge and a second edge; a first surface, the first surface having a static coefficient of friction less than 0.5; a second surface opposite the first surface, the second surface having a static coefficient of friction greater than 0.5; and wherein the at least one layer is joined along at least the first edge, forming the flexible bag and the second end is scored defining a tearing direction that allows the flexible bag to be torn open only along the tearing direction. the method comprising; removing the end cap; moving the second wall away from the first wall, opening the dispenser and exposing at least the chamber; positioning the flexible bag in the chamber such that at least the tear strip extends from the dispenser; moving the second wall towards the first wall, closing the dispenser; placing the end cap on the dispenser;
opening the tear strip in the tearing direction; anddispensing of the product and preventing the product from leaking into the chamber. - View Dependent Claims (47, 48)

41. A dispenser adapted to receive a flexible bag and dispense a product, the dispenser comprising:
-
a housing having a first wall and a second wall hingedly connected to the first wall and defining a chamber having a first end and a second end; a handle located proximate the chamber first end and having a trigger and a reversely biased actuating device; a segmented piston positioned in the chamber and actionably coupled to at least the actuating device; a locating device for aligning the flexible bag in the chamber; and an end cap adapted to be removably, rotatably received by the housing proximate the second end, the end cap defining at least one opening adapted to allow flow in only one direction, wherein the handle and segmented piston act in concert, such that upon completion of dispensing a predetermined amount of product, relieves any residual pressure on the flexible bag, preventing product weeping. - View Dependent Claims (42, 43, 44, 45, 46)
