A beverage container lid comprising a body having drinking hole and an air hole, and a slide-seal automatic Open and Close retention mechanism that comprises a sealing arm pivotally connected to the body, a movement and position retention linkage structured and operable to move the sealing arm between an Opened and a Closed position, a control mechanism slidingly disposed within the body and operably connected to the movement and position retention linkage such that movement of the control mechanism will control movement of the sealing arm between the Opened and Closed positions, and a biasing device structured and operable to exert constant force on the sealing arm, such that force exerted by the biasing device in combination with the structure and operation of the movement and position retention linkage will selectively retain the sealing arm in the Opened position and in the Closed position.

A beverage container includes a main body portion for accommodating a beverage and a lid portion provided on the upper portion of the main body portion, the lid portion includes a beverage opening portion (312) for discharging the beverage and a beverage opening and closing portion side sealing material (324) for opening and closing the beverage opening portion (312) from the lower side of the beverage opening portion (312), the lid portion further includes a gas opening portion (313) provided separately from the beverage opening portion (312) and for taking outside air into the main body portion in a case where the beverage accommodated in the main body portion is discharged and a gas opening and closing portion side sealing material (325) for opening and closing the gas opening portion (313) from the lower side of the gas opening portion (313).

The present invention relates to a pressure relief element (11) to be used as an overpressure safety means in devices where a gaseous medium must be rapidly released in case of overpressure, wherein the pressure relief element (11) has at least one notch (9) which is designed as a predetermined breaking point where the pressure relief element (11) breaks at a certain level of overpressure, thereby irreversibly opening an exhaust path for the gaseous medium. The present invention also relates to a pressure relief device of an electrochemical battery, comprising such a pressure relief element and a battery comprising such a pressure relief device.

A can for containing a liquid has a top end having a dispense area defined by a first score line and a pull tab coupled to the top end by a rivet. The pull tab has a puncturing end for breaking the first score line and pushing into the interior of the can without detaching the dispense area to open a dispense aperture. A vent area is defined by a second score line and positioned on the opposite side of the rivet. The first and second score lines are separated by at least one torsion stripe of the can top material for acting as a hinge by torsion upon lifting the actuating end of the pull tab. As the dispense aperture is opened by pushing the dispense area into the interior of the can, a vent aperture is opened by pulling the vent area outwards.

The present invention relates to a container assembly for accommodating a beverage. The container assembly comprises a collapsible beverage container having a body part for accommodating the beverage and a cylindrical neck part defining a gas-filled headspace. The container assembly further comprises a closure sealing off an opening of the cylindrical neck part. The closure comprises a closure disc, an inner cylindrical part and an outer cylindrical part. The closure disc comprises a beverage outlet for extracting the beverage. The closure further comprises a pressure-relief device located at the closure disc or the inner cylindrical part. The pressure-relief device is capable of establishing a permanent or reclosable opening through the closure or between the closure and the neck part for allowing a flow of fluid from the headspace to an external space when a pressure difference exceeds a predetermined pressure value being lower than the burst pressure of the container.

A container lid and base assembly includes lid and base stacking features, as well as base chamfers that align with vents provided in the lid. When a plurality of the container assemblies is stacked, the lid and base stacking features nest with each other, while the chamfers align with corresponding vents in the stacked assemblies so that none of the vents is blocked by a next-higher container assembly. The stacking features can be centrally located, and the vents can be peripherally located. A plurality of the container assemblies can have differing sizes and/or shapes, while including mutually compatible stacking features, thereby enabling container assemblies of differing sizes to be stacked without blocking any of the vents thereof. The vents can be holes or “C” vents. The lid and/or base can be manufacturable by thermoforming. The lid and base can be separate, or joined by a hinge.

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.

An expandable triangular pizza storage container with a set of microwaveable triangular trays for the separation, microwaving and serving of individual slices of pizza. The storage container has a series of concentric triangular compartments that are expanded from a flexible polymer, accordion-style container body. The lid also has a triangular configuration with a replaceable compressible gasket, a set of four locking wings extending from each side that frictionally engage a rigid triangular top ring of the container body, and a central vent. The trays may incorporate uniform concave pockets to facilitate crisping of the pizza crust in the microwave and be of a solid or cored design, of microwave and dishwasher friendly material.

A package is disclosed that includes a container and a closure. The container includes a container neck finish having a radially inner surface, a radially outer surface, and an axial outward end surface extending between the radially inner and outer surfaces. The radially outer surface includes a straight cylindrical upper portion and a threaded cylindrical lower portion. The closure includes a base wall engaging the axial outward end surface of the container neck finish, an external skirt extending away from the base wall and having a threaded section with internal threads engaging the container neck finish, and a pleated section between the threaded section and the base wall.
