The present disclosure is directed to a lid component for use with a jar and a band. The jar and band may be a mason jar and a band for a mason jar. The lid component is made of an air-impermeable material and is dimensioned and configured to be releasably attachable to the jar by the band and to seal a wide mouth opening of the jar in an air-tight manner. The lid component comprises a one-way valve adapted to allow gas to escape from the jar while, at the same time, prevent air from entering the jar, when the lid component is releasably attached to the jar. The one-way valve comprises a bottom opening and a protruding top wall. The lid component further comprises a sealing wall that extends radially outwardly from the bottom opening. The sealing wall is substantially flat.

An insulating container having a base and a lid is provided. The lid may be rotatable about a hinge from a closed configuration to an open configuration and may be secured, via one or more latching devices, in the closed configuration. In some examples, the insulating container further includes a pressure regulation device. In other examples, the latching devices further include an elastomeric latch upper and a semi-rigid latch lower configured to engage an insulating container keeper when the when the lid is in a closed and a secured position. In still other examples, the latch upper and the latch lower are configured in a recessed position, and flush with a front side of the insulating container lid and flush with a front side of a bottom portion of the insulating container when the latch device secures the lid in a closed position.

A cap assembly for a container comprises a cap and a body coupled to the cap. The body includes a peripheral wall and a valve seat. The valve seat includes a first side facing the cap and a second side facing away from the cap. A first check valve having an elastic valve body is positioned at the second side of the seat. A second check valve having an elastic valve body is positioned at the first side of the valve seat. When a pressure at the first side of the valve seat exceeds a pressure at the second side of the valve seat by a first predetermined value, the first check valve opens; and when the pressure at the second side exceeds the pressure at the first side by a second predetermined value, the second check valve opens.

A lid, for attachment to a container holding a liquid for use with a liquid spraying device, a vent duct defining a vent conduit extending through a lid body from a duct inlet end to a duct outlet end. A valve is disposed in the vent duct and is configured to permit air flow in a first direction, from the duct inlet end to the duct outlet end, while preventing liquid flow in a second direction opposite the first direction. A cap extends over the duct inlet end, the cap including a cap interior surface defining an interior air chamber, communicating with the vent conduit, and at least a first passage, communicating between the interior air chamber and a first cap inlet. A tube is coupled to the duct outlet end and has a tube outlet end fluidly communicating with an interior of the container.

A self-venting self-resealing pre-cut elastomeric closure for vials, bottles and the like, comprising a dished elastomeric septum supported for closing an opening in a container, a cut across the dished elastomeric septum, and additional cuts defining with the cross cut one or more flap areas elastically displaceable from a closed condition to a venting condition in response to insertion of a liquid transfer implement through the central area of the septum dish.

A valve assembly for a leak resistant drinking cup includes a tubular plug having an outer wall, an inner wall, and a web extending between and connecting the outer and inner walls. The web has at least one slit disposed intermediate the inner and outer walls. The valve assembly is configurable between a sealed position wherein liquid is inhibited from passing through the slit and an unsealed position wherein liquid can pass through the slit.
