Closure for a container mouth, the closure comprising: a cover portion (18) for covering at least a portion of the container mouth; a fastener portion (20) for engaging the container for fastening the closure to the container; and a peelable bracing portion (22) extending generally in a circumferential direction of or around an axis of the closure, the bracing portion overlapping at least partly the cover portion and the fastener portion, and configured to reinforce the closure by bearing, as shear stress at an interface between the bracing portion and at least one of the cover portion and fastener portion, support force in or between one or both of the cover portion and the fastener portion.

A child resistant container can include a container body, a closed base, an open top, an exterior and a cap assembly configured to couple to the container body for closing the container. A cap assembly can include an inner cap configured to couple to a container body and an outer cap coupled to the inner cap. A first coupler can be coupled to the inner cap and a second coupler can be coupled to the outer cap and configured to optionally engage the first coupler. An outer cap can be configured to rotate relative to an inner cap when the outer cap is in one or more positions and to engage the inner cap when the outer cap is in one or more other positions. A child resistant container can be made from recyclable metal.

A two-piece mason jar lid is described, with said mason jar lid capable of being secured to a mason jar in the typical manner using a threaded band or ring. The two-piece mason jar lid includes an annular lid component and a circular lid component that can be rotatably disposed within the annular lid component. Indicia and indicators disposed on the annular lid component and circular lid component work in cooperation, such that rotation of the circular lid component causes the indicator to be aligned with the desired indicia, to, for example, indicate a date upon which fermentation within the mason jar may be complete. The annular lid component or circular lid component can also include one or more venting channels to permit venting of fermentation gases, while preventing air from entering the mason jar.

A composite closure including a panel and an outer portion defining a recess into which the panel is received. The composite closure may be coupled with a container. The panel deflects downward toward the container when the composite closure is sealed with the container and the interior of the container is under vacuum.

A canister includes a container and a closure. The container is formed to include a product-storage region and an open mouth that opens into the product-storage region. The closure is configured to couple to the container to close the open mouth.

A canning system for a jar is described. The system includes a plunger configured to translate through a neck of the jar. A seal is in communication with the plunger and configured to flex its shape so as to conform to the size of the jar as it passes through the neck. The seal extending beyond the periphery of the plunger. A rod is configured to engage the plunger and selectively locate the position of the plunger within the jar. An optional cap may be used to assist in locating the plunger in the jar prior to sealing the jar with a lid.

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 container, preferably in the form of a bucket, includes a closure for closing the container. The closure includes a closed lid plate that is placeable on a container rim bounding a container opening in order to cover the container opening. A lock ring is placeable over the lid plate and screwable to the container. The lid plate is fixable to the container with the lock ring. A seal ring is arranged between the container rim and lid plate for sealing the container opening. The lid plate has a rim portion with a receiving portion, in particular U-shaped, that receives the container rim and encompasses the container rim radially from the inside and outside.

The present application is directed to closure assemblies, and particularly closure assemblies for closing an opening in a vessel. In particular embodiments, the closure assemblies described herein can have a first ring having a top surface, an inner surface and an outer surface, wherein the outer surface comprises threading, wherein the first ring comprises a first flange having a top surface extending radially inward from the inner surface of the first ring a distance of F.sub.L, and wherein the top surface of the first flange is spaced apart from the top surface of the first ring by a distance F.sub.H, and wherein a ratio of F.sub.H:F.sub.L is greater than 1.

A two-piece mason jar lid is described, with said mason jar lid capable of being secured to a mason jar in the typical manner using a threaded band or ring.
