Abstract: A breakseal providing desired compliance characteristics for a reliable seal between the fitment of a liquid dispenser and the breakseal. A compliant material is provided on the non-wetted face of the breakseal, enabling compliance of the breakseal on a wetted face for sealing between the breakseal and the mating component. The breakseal may also include raised features on segments that are separated after rupturing that prevent or mitigate scoring of O-ring seals upon probe insertion. A wiping feature that provides redundant sealing between the breakseal and a mating cap or other mating connection may also be incorporated into the breakseal. The breakseal can also include a flat on an outer perimeter that may serve as a gate for injection molding, so that any gate vestige from the molding process will not protrude beyond the outer diameter of the breakseal to cause unwanted interference between the breakseal and the mating connection.

Abstract: A method for manufacturing a liner, the method including forming a tubular body portion having a top circumferential edge, a bottom circumferential edge, and a weld seam or seams extending from the top circumferential edge to the bottom circumferential edge; stretching the tubular body near the top circumferential edge and welding a top liner sheet portion along the stretched top circumferential edge, the top liner sheet portion having a fitment welded thereto; and stretching the tubular body near the bottom circumferential edge and welding a bottom liner sheet portion along the stretched bottom circumferential edge. The weld between the tubular body portion and the top liner sheet portion may be effected with the inner wetted surfaces of each portion in contact. Similarly, the weld between the tubular body portion and the bottom liner sheet portion is effected with the inner wetted surfaces of each portion in contact.
