ABSTRACT:
An inventive valve member, and associated method of making, for use in a bag for holding a gas or liquid, the bag including a main body having a stem portion, the main body defining an interior space and formed from a front and back sheet sealed together about a peripheral edge. The stem defines an inlet aperture at a free end thereof. A valve member has a width dimension positioned in the stem for use in inflating the main body, the valve member including a flexible front layer and a flexible back layer. The front layer is adjacent to the front sheet, and the back layer is adjacent to the back sheet. Both the front and back layers define opposing elongated edges. The front and back layers are attached together along the elongated sides to form a seal. The valve member has an inlet end and an outlet end, the inlet end is adjacent to the inlet aperture, and the outlet end is positioned in communication with the interior chamber of the main body. A front valve seal is formed between the top layer of the valve member and the top sheet of the stem portion. The top valve seal is positioned adjacent to the inlet end of the valve member, the front valve seal extending substantially perpendicularly from the longitudinal edges of the valve member and curves forwardly toward said inlet end of said valve member at a central location across said width dimension to define a front leading edge. A bottom valve seal is formed between the bottom layer of the valve member and the bottom sheet of the stem portion. The bottom valve seal is positioned adjacent to the inlet end of the valve member, and the back valve seal extends substantially perpendicularly from the longitudinal edges of the valve member and curves forwardly toward the inlet end of the valve member at a central location across the width dimension to define a back leading edge.
