摘要:
A flexible container has flexible top and bottom handles for facilitating dispensing of a flowable substance stored therein. The container includes a flexible panels enclosing an interior of the container and forming a top segment, an opposite bottom segment, a front side segment, a rear side segment, and a pair of side segments bounding the interior. A rigid fitment provides an access opening through either the top segment or a front side segment. A flexible bottom handle structure surrounds a handle opening. It is defined by at least one of the flexible panels, the bottom handle structure being positioned along a center portion of the bottom segment between the front side and rear side segments. The bottom handle has a folded portion at the opening to provide a smooth gripping surface.

A container including a fitment providing a closure and a plurality of panels of plastic film. Each of the panels has a pair of opposing longitudinal edges with each edge joined to a longitudinal edge of an adjacent panel to form an outwardly extending seam. The panels collectively form a tube-like structure. A first end of the tube-like structure is sealed to the fitment. An opposing second end of the tube-like structure is closed by seams joining adjacent panels. A first portion of each of the panels adjacent the second end of the tube-like structure is expanded such that the first portion of each of the panels is not flat. A second portion of each of the panels between the first end and the second end is left substantially unexpanded such that the second portion of each of the panels is substantially flat.

A method for fabricating a fitmented flexible bottle is disclosed which involves feeding webs including one or more gussets, creating perimeter seals around only the top portion of the bottle, inserting the fitment from the input end of the machine in the direction of web travel, forming the remainder of the perimeter seams, detaching the nascent bottle from the web, and sealing the neck section of the bottle to the fitment by clamping the neck section with a heated clamp, and preferably repeating the seal operation at a different radial angle. Sealing the fitment by application of ultrasonic energy is also disclosed. In another embodiment, the fitment is sealed to the neck section of the bottle by utilizing heated wheels against the neck and rotating the bottle to create a seal all around the neck.

摘要:
A plastic bottle includes an expanded blow-molding preform of plastic film. The expanded preform has a base configured to support the bottle in a free-standing upright position, a neck containing a fitment, and seams including only a single full-height seam extending from the base to the neck.
