A container closure. The closure comprises a pressure closure assembly and an outer release shell configured to be coupled thereto. The assembly comprises a relief valve and an inner shell having a base wall, a pressure relief slot, and an outer skirt extending away from the base wall and including first and second portions. The release shell includes a first portion having a base wall configured to overlap a portion of the inner shell base wall, and a tab corresponding to the slot of the inner shell. The first portion further includes an outer skirt extending away from the first portion base wall and configured to wrap around the first portion of the outer skirt. The release shell further includes a second portion having a base wall configured to overlap a portion of the inner shell base wall, and an outer skirt extending away from the second portion base wall.

A rectangular perimeter egg carton comprising: a lid, and a base separate from the lid, wherein the lid and base are assembled together to from a closed egg carton, the base having a top wall and a rectangular array of recessed base cells arranged in rows and columns depending from the top wall, each base cell having an open top end, a sidewall and a closed bottom wall and being sized and shaped to hold one egg in a generally upright position with the long axis of the egg disposed in a vertical direction transverse to a base reference plane in which the bottom walls of the base cells reside; the base and lid having respective mating rectangular perimeter edges, including opposing front and rear side edges and opposing left and right side edges, that mate with each other in a closed position to from the rectangular perimeter egg carton for enclosing an egg in each of the respective cells; and a plurality of spaced apart venting ports formed in each of the perimeter side edges of one or more of the base and lid perimeters for releasing moisture from the closed egg carton.

The present disclosure describes a cup system for simultaneous delivery of contents from separated cups to a mouth of a user. The cup system includes an outer cup, an inner cup, a lid, and a cap. The outer cup includes an upper lip with a threaded surface configured to engage with a mating threaded surface of a lid. The inner cup includes an engaging lip configured to engage with a lower inner lip and configured to form a seal between the inner cup and the lid, as well as a flange located below the engaging lip that extends outward from a periphery of the inner cup. The lid includes an outer wall with a lower outer lip comprising the mating threaded surface, the mating threaded surface is configured to engage with a threaded surface. The cap includes a mating engagement feature configured to engage with an inner wall engagement feature.

The present disclosure generally relates to a venting system that includes a lid or base with a center wall that defines a central longitudinal axis, and a total radius that is measured from the longitudinal axis to an outermost surface of the lid or base. The venting system further includes a pressure relief feature that is disposed along the lid or base. The pressure relief feature includes at least a first venting feature defining a thinned region of the lid or base, a venting radius is measured from the longitudinal axis to an outermost extent of the first venting feature, and the venting radius is between about 5% and about 25% of the total radius of the lid or base.

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.

A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

A food container including a receptacle defining a first storage volume and a second storage volume, a cover configured to be secured to the receptacle, and a gas diversion system located between the first storage volume and the second storage volume when the cover is secured to the receptacle.

A food container including a receptacle defining a first storage volume and a second storage volume, a cover configured to be secured to the receptacle, and a gas diversion system located between the first storage volume and the second storage volume when the cover is secured to the receptacle.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.
