A lid-to-container locking combination maximizes lid-to-container retention and includes a container and a container lid. The container includes an upper container rim and a container wall. The container wall includes a radially outwardly extending indentation or groove located in inferior adjacency to the upper container rim at an inner surface thereof. The container lid includes a rim-receiving groove, a lid wall, and a wall-to-groove resilient portion. The resilient portion traverses a structural distance between the lid wall and the rim-receiving groove and is resiliently actuable intermediate a relaxed configuration and an actuated configuration. The resilient portion includes a radially outer indentation-engaging portion. The rim-receiving groove receives the upper container rim, and the indentation-engaging portion engages the radially outwardly extending indentation when in the actuated configuration. The rim-receiving groove and radially outer the indentation-engaging portion together lock the container lid to the liquid container for cooperatively maximizing lid-to-container retention.

A paper lid for a container includes a body portion, a top lid portion having an outer periphery surrounded by the body portion, and an engaging portion in the body portion that includes a tapered portion tapering in the same direction as the container taper and engages with the container curl portion. The body portion has a first end portion for mounting on the container and an opposite second end portion. The outer periphery is bent toward the first end portion, and has a bent portion bonded to the body portion. A part other than the outer periphery is between the engaging portion and the second end portion. An inner diameter of a tip of the tapered portion is smaller than an outer diameter of the container curl portion. Where the lid closes the container opening, the container curl portion contacts an inner part of the tapered portion.

A reusable vessel comprises a first compartment to store therein a substance and a second compartment separated from the first compartment by a boundary element comprising a wall or membrane having one or more apertures therein. A valve is movable between a closed position, in which the valve seals the one or more apertures, and an open position allowing the substance to be released from the first compartment into the second compartment, or a substance in the second compartment to mix with the substance in the first compartment. A triggering mechanism is coupled to the valve to move the valve between the open and closed positions. The triggering mechanism comprises one or more external elements coupled to one or more internal cam elements to control the valve, which, when triggered causes the one or more external elements to exhibit a visible change to indicate the open and closed positions of the valve.

A bowl and lid set includes a lid member that has a top lid wall and a first surrounding wall extending downwardly from the top lid wall, and a bowl member that includes a bottom wall and a side wall extending upwardly from a periphery of the bottom wall. The side wall has an upper engaging portion that is made of an elastic material and that is deformable from a non-deformed state, where the bowl member is disengaged from the lid member and where a minimum inner diameter of the upper engaging portion is smaller than a maximum outer diameter of the first surrounding wall of the lid member, to a deformed state, where the upper engaging portion is resiliently stretched for tightly encircling the first surrounding wall.

A container for liquid food substances which comprises a first containing element (1) having a first body (2) delimiting a cavity (4), and a closing part (5) for closing the cavity (4). The first body and the closing part (5) are made of a metal material. A second containing element (8, 108) made of plastic material for foodstuff, which comprises a first part (9, 109) suitable to be completely housed in the first containing element (1). A neck (10, 110) departing from an upper wall (9A, 109A) of the second containing element (8, 108), suitable to cross the through opening (6) of the closing part and provided with an outflow part (11, 111) projecting outside the closing part suitable to allow the food substance to flow out of the container. The outflow part (11, 111) having mechanism (12, 112) for removably connecting a cap (13) for tightly sealing the container.

A sealed container capable of knowing that the opening of the container body is exactly in close contact with a packing when a lid body is attached to the container body. The sealed container has a container body, a lid body attached to the opening of the container body, and a packing attached to the lid body, while the packing has a packing body provided in the lid body and a plurality of flexible ring-shaped protrusions provided thereupon which are mutually separated in the axial direction of the lid body The outer peripheral portion of the ring-shaped protrusion, which is the farthest from the top plate portion of the lid body in the axial direction, is in close contact with the inner peripheral surface of the container body, while the outer peripheral portions of other ring-shaped protrusions are radially separated from the inner peripheral surface of the container body.

A reusable beverage container has a glass cup having a formed mouth having a smooth exterior frustoconical surface which widens in exterior diameter towards a rim of the mouth. The mouth has a height of greater than 15 mm. A lid engages the mouth. The lid has a top section and an elastomeric skirt, the top section having a drinking aperture therethrough and the skirt defining an inner frustoconical surface and an outer surface. The inner frustoconical surface conforms in shape and size to the outer frustoconical surface and the skirt thickening towards a lower edge thereof.

A storage container comprised of a container bottom, and with multiple sealable covers, configured to connect the covers to the container bottom in both open and closed arrangements. Additionally, each of said covers will seal to the container bottom, and each of said covers will seal to an opposing cover. The containers may be proportioned to stack or nest into other open containers, as well as on top of containers with closed covers. The containers may also allow open covers to rest vertically alongside the container without significantly contacting the surface the container is resting on.

A container lid may include a lid body having a generally planar top portion and a circumferential sidewall extending downward from the top portion thereof. A rib member extending downward from the top portion of the container lid may be spaced inward from the sidewall defining a circumferential channel therebetween configured to receive an open end of a container and form a watertight seal about the container. The top portion of the lid body may include a recessed portion adapted for forming a secondary seal with the container.

A container and a cover having a sealing structure includes: the container including a bottom and a side wall having one end connected to the bottom to form a space, and another end of the side wall that is not connected to the bottom is an open end, the side wall having an inner surface and an outer surface, the inner surface faces the space, and the inner surface has a first hook portion; and the cover disposed at the open end of the container, the cover has a covering portion and a second hook portion, the covering portion covers the open end, and the second hook portion is hooked on the first hook portion. The covering portion tightly covers the open end, and the second hook portion is hooked to the first hook portion, so that the coupling between the cover and the container is more stable.
