A fluid storage system includes a container defining an interior space that lacks an internal valve. A product and a propellant are stored under pressure within the interior space. A container cap includes a membrane that encloses a space defined by a coupling element, which includes a releasable fastener that releasably couples a fluid dispensing apparatus to the container. The container cap also includes a dip tube comprising a proximate end that extends at least partially into the space defined by the coupling element, and a distal end that protrudes from the space in a direction generally away from the container cap, into the interior space defined by the container. The dip tube defines an interior passage extending between the proximate end and the distal end through which the product is to be expelled from the container by the propellant.

A fluid dispensing apparatus may be used to dispense a fluid from a container that is under pressure and that has a pierceable membrane. The fluid dispensing apparatus may include a valve body having a bore, an adaptor having a bore and a piercing member, and a nozzle having a bore. The fluid dispensing apparatus may be operable to pierce the pierceable membrane to communicate the fluid within the container with the adaptor bore and with the valve body bore. The nozzle may be operable to permit the fluid to flow under the pressure out of the container, through the adaptor bore, through the valve body bore and through the nozzle bore to ambient.

Pressure relief blow out plugs for a container are disclosed as well as methods of using the same. One disclosed method involves providing a glass container that comprises a base and a body extending away from the base. The base includes a wall that defines a pressure relief passage. The method also involves inserting a pressure relief blow out into the pressure relief passage to seal the passage. The plug comprises a first inboard flange extending radially outwardly from the plug body, a stem, and a second inboard flange extending radially outwardly from the plug body and being spaced apart from the first inboard flange by a stem. The first inboard flange includes a first outboard sealing surface that provides an axial seal against the wall of the base of the glass container, and the second inboard flange including a circumferentially interrupted outboard facing retention portion the defines vent gaps.

A method for releasing residual pressurized fluid from an aerosol canister, said method comprising the manual opening of a vent assembly (614) for said canister (600), the vent assembly (614) comprising first (615) and second (616) members and a receiving part (617), the receiving part (617) having an outer surface configured to form a fluid seal against an edge of a hole in the canister (600), and an internal volume having a longitudinal axis, the second member (616) disposed within the internal volume of the receiving part (617) and configured for linear translation along the longitudinal axis relative to the receiving part (617), the first member (615) rotatably engaged with the second member (616), rotation of the first member (615) relative to the second member (616) configured to impart translation of the second member (616) along the longitudinal axis such that, in a first position, the second member (616) forms a fluid seal against the receiving part (617) and, in a second position, a fluid passage is formed between the second member (616) and an inner surface of the receiving part (617).

A plastic container for storing a product. The container includes a base formed of a plastic material and sidewalls formed of the plastic material and extending upwardly from the base, ending in an open top adapted to be closed by a cap, and with the base defining an interior volume. The container also includes a snapping frame integrally formed in the base of the plastic material. The frame has a convex base shape before activation when the pressure in the interior volume is less than or equal to a predetermined critical pressure and has a concave base shape immediately after activation when the pressure in the interior volume is greater than the predetermined critical pressure, thereby increasing the interior volume and avoiding catastrophic failure of the container. Also disclosed are a method of using the container and a process of manufacturing the container.

The present disclosure generally relates to a venting system that includes a wall of a lid or a container, the lid or container defining a central longitudinal axis, and a line segment that is measured from the longitudinal axis to an outermost surface of the lid or container, and a pressure relief feature that is disposed along the lid or container. The pressure relief feature includes a thinned region of the lid or container that defines a minimum thickness that is less than 40% of a maximum thickness of the respective lid or container. The pressure relief feature extends at least 180 degrees about the longitudinal axis, and the pressure relief feature is located at a distance from the longitudinal axis of more than 80% of the line segment.
