A seal releasing lid assembly includes a lid configured for coupling across a container opening of a container. The lid includes a lid surface and a lid wall extending from the lid surface. The lid wall includes a lid edge and a slidable coupling surface between the lid edge and the lid surface. The assembly includes a retaining and releasing ring configured for coupling with the container and with the lid. The retaining and releasing ring includes a ring flange and a release ridge. A ring wall extends from the ring flange to the release ridge. The retaining and releasing ring includes decoupling and release ready configurations. In the decoupling configuration the release ridge is slidably coupled along the lid wall. In the release ready configuration the release ridge is seated beneath the lid edge and slidably disengaged from the lid wall.

A package seal for sealing engagement between a closure and a container, and including an elastomeric seal ring with a sealing portion, and a plastic projection coupled to the seal ring.

A closure assembly comprising a two-part closure having a metal panel or disc (2) and a ring (3), and a container such as a glass jar (20). The ring (3) is substantially cylindrical with an axially upwardly extending sidewall and has a radially inwardly extending lower edge. The jar (20) terminates in a radially outwardly extending beaded rim (16) and the disc (2) has a curled circumference (8) such that this curl (8) co-operates with the beaded rim (16) of the container to provide a primary seal. In one example, in a metal ring (3), the lower edge is curled with equally spaced lugs (13) on the skirt wall. In a plastic ring, the upper rim feature may be omitted.

A closure includes an overcap having an annular skirt, and an annular wall extending inwardly from the skirt. A lid is carried by the overcap radially within the annular skirt, and includes a hub, and an annular margin extending radially outwardly with respect to the hub, and having upper and lower surfaces. An annular container seal extends circumferentially continuously around the annular margin. One or more vents may extend through the annular margin between the upper and lower surfaces thereof at one or more discrete circumferential locations radially inward with respect to the container seal. One or more vent seals may be disposed at the one or more vents between the lid and the overcap.

A closure assembly for filling a container under isolated conditions. The closure assembly includes a collar with internal threads for coupling with a finish of the container. A disc includes first coupling members for removably coupling with the collar. A liner is secured to the disc. The liner is seated on the finish of the container when the collar is coupled to the finish.

A markable bottle cap is characterized by a cap configured for use with a variety of bottles, jars, or containers wherein the upper surface of the cap is configured to receive at least one marking by a user. In some embodiments, the upper surface may provide for a scratch-off layer, a rough texture layer, or a magic slate layer. To use the present invention, a user may, in any order, threadedly attach the cap to a container such as a bottle or jar, apply at least one marking to the upper surface, and then identify the user's beverage as needed.

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).

Disclosed is a device for protecting and preserving a substance in a container. The device may include a plurality of overlapping sectors capable of rotating about a pivot point such that the device has a substantially disc shape when fully expanded and a substantially pie shape when partially expanded; and a lip defining an outer diameter of the device when fully expanded. The outer diameter of the device is equal to or greater than an inner diameter of the inner surface of the container.

A closure includes a polymeric top wall portion, a polymeric liner, a polymeric disc and a polymeric annular skirt portion. The polymeric disc is located between the polymeric top wall portion and the polymeric liner. The polymeric annular skirt portion depends from the polymeric top wall portion. The annular skirt portion includes: (1) an internal thread formation for mating engagement with an external thread formation of a container; and (2) an internal prying projection to assist in removing the closure from the container. At least a portion of the internal prying projection is located nearer the polymeric top wall portion than the internal thread formation.
