A lid element for use with a canning container includes a centrally disposed domed portion, an annular channel portion disposed radially outwardly of the domed portion, and an annular peripheral portion disposed radially outwardly of the channel portion. The peripheral portion is configured to be axially aligned with a rim of the canning container about a circumference of the rim when the lid element is engaging the rim. The channel portion extends away from each of the domed portion and the peripheral portion with respect to an interior axial direction corresponding to an axial direction of the lid element towards the interior of the canning container when the lid element is engaging the rim.

A resealable, vacuum packable receptacle has a container, a sealing layer, an inner lid, and an outer lid. When (i) the outer lid opening receives the inner lid, (ii) the inner lid is threadably mated with the container, and (iii) the container has the sealing layer positioned over the container's mouth; (A) a portion of the outer lid causes the outer lid or the inner lid to contact the sealing layer to push a desired amount of air from the container which then results in inhibiting air from entering or exiting the container, or (B) the distance between the outer lid's top surface and the inner lid's top surface can be altered, and when the distance is increased, the air pressure in the container is decreased.

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.

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.

The container with a lid attached to a threaded closure mechanism includes a receptacle having a mouth surrounded by a thread, a lid, a sealing ring and a closure mechanism formed by a disc with a hollow interior and a perimetral tubular skirt provided with an engagement configuration complementary to the thread of the receptacle. The closure mechanism surrounds the lid and holds it against the mouth of the receptacle by means of a threaded attachment between the engagement configuration of the closure mechanism and the thread of the receptacle, assuring proper hermetic closure of the lid with the receptacle in cooperation with the sealing ring and a retainer element connected to the closure mechanism to constrict an insertion passage thereof thereby retaining the lid into the closure mechanism.

A vessel closure (1, 21, 41, 61) includes a sealing element (3, 23, 43, 63). The sealing element (3, 23, 43, 63) includes a polymer composition. The polymer composition includes a polyalphaolefin with kinematic viscosity, determined according to ASTM D445 / ISO 3104, of at least 4 cSt, at a temperature of 100° C., and/or a dropping point, determined according to ASTM 5950, of at most -10° C., and up to 95% by weight of a second polyolefin.

A container with a reusable cap, including a glass receptacle (10) with a receptacle opening (11) surrounded by an annular mouth (12) and by a cylindrical neck (13) including a retention configuration; a cap (20) including a closing portion (30) completely covering the receptacle opening (11) and an engagement portion (40) made of a metal sheet; a releasable closure mechanism connecting the engagement portion (40) with the retention configurations and a sealing ring (50), the engagement portion including radial protrusions (41), directed inwards and determining a local narrowing, the sealing ring (50) being not adhered to the cap and being retained within the cap (20).

The container with a lid and threaded closure mechanism includes a receptacle having a mouth surrounded by a thread, a lid, a sealing ring and a closure mechanism formed by a disc with a hollow interior and a perimetral tubular skirt provided with an engagement configuration complementary to the thread of the receptacle. The closure mechanism surrounds the lid and holds it against the mouth of the receptacle by means of a threaded attachment between the engagement configuration of the closure mechanism and the thread of the receptacle, assuring proper hermetic closure of the lid with the receptacle in cooperation with the sealing ring. The lid and the closure mechanism have mutually engaging elements with a complementary non-circular geometry and size, with both elements being tightly fitted preventing relative rotation of the closure mechanism with respect to the lid.

A container provided with a sealing lid comprises a jar (11), a lid (12) for closing the jar, a rubber sealing ring (13), adapted to be interposed between an upper edge (17) of the jar (11) and a lower flange (18) of the lid (12), and a wire-shaped hooking element (14) of the lid (12) to the jar (11) for closing the container. The jar (11) is provided, in the proximity of its upper edge (17), with a collar (21) radially projecting from the jar side surface (22) so as to define below a circumferential step-like seat (23). The wire-shaped hooking element (14) is shaped with a pair of pivoting ends (20) rotatably received inside respective holes (19) in the lid (12) and with at least one curvilinear locking portion (24), in an intermediate position with respect to said pivoting ends (20).
