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.

Molded fluoropolymer breakseal with compliant material

The present disclosure relates to an integrated liner-based system having an overpack and a liner provided within the overpack, the liner comprising a mouth and a liner wall forming an interior cavity of the liner and having a thickness such that the liner is substantially self-supporting in an expanded state, but is collapsible at a pressure of less than about 20 psi. The liner and overpack may be made by blow molding the liner and the overpack at the same time using nested preforms.

Nested blow molded liner and overpack and methods of making same

The present disclosure relates to a blow-molded, rigid collapsible liner that can be suitable particularly for smaller storage and dispensing systems. The rigid collapsible liner may be a stand-alone liner, e.g., used without an outer container, and may be dispensed from a fixed pressure dispensing can. Folds in the rigid collapsible liner may be substantially eliminated, thereby substantially reducing or eliminating the problems associated with pinholes, weld tears, and overflow. The present disclosure also relates to flexible gusseted or non-gusseted liners, which is scalable in size and may be used for storage of up to 200 L or more. The flexible gusseted liner may be foldable, such that the liner can be introduced into a dispensing can. The liner can be made of thicker materials, substantially reducing or eliminating the problems associated pinholes, and may include more robust welds, substantially reducing or eliminating the problems associated weld tears.

Breakseal for a liquid dispensing system

The present disclosure relates to novel and advantageous connector assemblies for use with a liner-based assembly. In one embodiment, a connector assembly for use with a liner-based assembly can include a pressure port, a dispense port, a headspace removal port, and a locking mechanism. The pressure port can be adapted for connection to a pressure source. The dispense port can be adapted for fluid communication with a source of material to be dispensed from the liner-based assembly. The headspace removal port may be configured for removing a gas from the liner-based assembly. The locking mechanism may be used for locking the connector to the liner-based assembly when contents therein are under pressure. In some embodiments, the dispense port and headspace removal port may be operably coupled providing a flow path for recirculation of the contents within a liner of the liner-based assembly.
