A lid consisting of fibrous material, in particular of fibrous material containing cellulose fibers, for at least partly covering an opening of a container is provided. The lid comprises a domed portion which is configured to at least partly cover the container opening and an attachment portion which externally surrounds the domed portion at least in portions. The lid attachment portion is configured to attach the lid to a counter attachment portion in the region of the opening of the container, preferably on an opening edge delimiting the container opening of the container. The lid can be formed at least in portions, preferably completely, from a uniform material with respect to its constituents, and the lid can have material characteristics which differ in different regions within a portion of a uniform material composition.

Disclosed herein is a dispensing assembly for dispensing flowable material from a container. The dispensing assembly has a spout that communicates with the flowable material and defines a spout retention element. The assembly further has a cap configured to releasably attach to the spout. The cap has a first collar and a second collar, the first collar defining a cap retention element. The cap retention element is configured to contact the spout retention element such that the cap is affixed to the spout, and the engagement between the cap retention element and the spout retention element is reversible, such that the cap is removed from contacting the spout.

A cap for a container can include a disc-shaped top section, an annular side section projecting from the disc-shaped top section, and a locking flange disposed at an extremity of the annular side section opposite the disc-shaped top section. The cap can further include a locking flap extending from the annular side section, and the locking flap can be mobile between a locked first position in which a portion of the locking flange extends inwardly from the annular side section and an unlocked second position in which the locking flange is at least partially recessed relative to the annular side section.

A container system includes a first container including a bottom wall, at least one sidewall, and an open top, with a plurality of indented recesses formed in the bottom wall. A first lid closes the open top of the first container. A second container includes a bottom wall, at least one sidewall, and an open top. A second lid closes the open top of the second container, with a push indicator structure formed at a center portion of the second lid, and with a plurality of registration bumps formed about the push indicator structure. The first container is stackable on the second lid such that (i) each of the registration bumps in the second lid is aligned with an adjacent one of the recesses in the bottom wall of the first container and (ii) surfaces of the registration bumps are spaced from surfaces of the adjacent recesses.

A sealed container with an inner lid 1a includes an openable and closable outer lid 3 to cover an opening 24 of a container body 2; and an inner lid 5a including a frame 53 having a flange 52 on its upper end and a circumferential outer side-surface 55, and an easily elastically deformable partition 51 having a dome shape projecting downward inside the frame 53. The outer lid includes a central area 12 having a dome-shaped concave portion inside a top face portion 10, and a peripheral area 13 surrounding the concave portion. The central area faces the partition and the peripheral area contacts the flange portion in a closed state. The central area has an inner surface formed such that, when the partition deforms to project upward, a surface area of the deformed partition is equal to or smaller than an initial surface area thereof.

A delaminatable container, including: a container body; and a press-fit cap mounted to the container body. The container body is configured to include a storage portion to store contents and a mouth having an opening to discharge the contents from the storage portion, the storage portion and the mouth having an outer layer and an inner layer, and having an inner bag composed of the inner layer to be shrunk with a decrease in the contents, the mouth includes a mouth-side engagement section provided along an outer circumferential surface of the mouth, the cap includes a cap-side engagement section provided along an inner circumferential surface of the cap, the mouth-side engagement section and the cap-side engagement section are configured to be engageable with each other while the cap is mounted to the mouth.

A cap (100) for a container comprises a disc-shaped top section (102), an annular side section (104) projecting from said disc-shaped top section (102), and a locking flange (111) disposed at an extremity of said annular side section (104) opposite said disc-shaped top section (102), and further comprises a locking flap (116) extending from said annular side section (104), which is mobile between a locked first position wherein a portion (114) of the locking flange (111) extends inwardly from the annular side section (104), and an unlocked second position wherein the locking flange (111) is at least partially recessed relative to the annular side section (104).

A container system includes a first container including a bottom wall, at least one sidewall, and an open top, with a plurality of indented recesses formed in the bottom wall. A first lid closes the open top of the first container. A second container includes a bottom wall, at least one sidewall, and an open top. A second lid closes the open top of the second container, with a push indicator structure formed at a center portion of the second lid, and with a plurality of registration bumps formed about the push indicator structure. The first container is stackable on the second lid such that (i) each of the registration bumps in the second lid is aligned with an adjacent one of the recesses in the bottom wall of the first container and (ii) surfaces of the registration bumps are spaced from surfaces of the adjacent recesses.

Provided is a plugging-type resin cap which can sufficiently seal a container and in which, upon uncapping of the container, a restraining band loosens after the pressure in the container is released without the application of an excessive force. A plugging-type resin cap (100) includes a restraining band (130), a tab (140), and engagement projections (151). The restraining band (130) has an arcuate restraining portion (131), stoppers (132), and an upwardly projecting portion (133). The stoppers (132) are formed to extend radially outward from the circumferential both ends of the restraining portion (131). The engagement projections (151) are disposed over an outer side surface of a skirt wall (120) in the vicinity of the circumferential both ends of a tab (140). The stoppers (132) and the engagement projections (151) are formed to be fittable with each other.
