A container having a pair of side walls and end walls and corner walls being provided between a respective end wall and side wall, a flange formed on one of the corner walls, said flange functioning as a hinge, a ring member formed integrally with the flange, the ring being sized to sit on top of the container.

A lid for a cup for beverages may include an annular lid bottom part, which can be placed on an upper cup edge, and a substantially circular lid disk. The lid bottom part and lid disk may be made of paper and may be connected in a liquid-tight manner along an edge groove pointing downwards in the direction of the cup and along an edge flange. The edge flange may point upwards in the opposite direction and may be inserted in the edge groove.

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 storage box that includes a container and a lid, which includes a bottom plate, a top plate, a top plate anchor and a movable latch. The bottom plate includes an arm that the height of its left section is bigger than the height of its right section, and its inclined middle section inclines from left to right. The movable latch includes a protrusion that its left section is flat and the inclined right section inclines and descends from left to right. The movable latch is designed to be positioned between the top plate and the bottom plate, in a way that the horizontal protrusion is inserted under the horizontal arm of the bottom plate and the movable latch can be moved from right to left and back.

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.

This disclosure provides a box lid and an airtight box and belongs to the technical field of food preservation boxes. The box lid comprises: a lid body; and a sealing ring connected to the lid body, the sealing ring comprising an inclined portion inclined inwards, wherein the inclined portion can produce elastic deformation and is deformable to a sealing state. The beneficial effects of this disclosure are as follows: The specially designed sealing ring allows the airtight box to maintain an airtight effect when the interior is in a positive pressure environment, so the airtight box does not need air release after being sealed. When the box lid reaches the sealing position from the contact position, the air pressure in the box increases to assist the inclined portion of the sealing ring to achieve sealing.

The invention disclosed is an intermediate-volume, dimensionally scalable container having a large transmural aperture providing easy access to contents and a resealable lid providing quick and repeated access to the contents. In one embodiment the invention provides a clear visible indication as to the locked or unlocked state of the lid and is adapted to readily incorporate different forms of tamper proof and tamper evident seals. The invention includes an assembly of similar containers of the same or different volumes having recessed bottom portions to receive the upper portion and lid of a vertically adjacent container when stacked and at least two opposing sides having complementary surface deformations to facilitate side-to-side mating of such containers when shipped, displayed for sale or stored.

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.

The present application provides a storage box lid, a storage box and a method for manufacturing the same. The storage box lid comprises a flexible thin film and a plastic rigid frame. The flexible thin film is prepared from a two-component platinum contented liquid silicone. In the present invention, the storage box, formed by using the storage box lid with the flexible thin film, in combination with a matching box body, can significantly improve the capacity for storing food, so that it can effectively store food larger than the box body. Moreover, the storage box of the present invention does not significantly squeeze the stored food, and the effect is distinctive.

A lid assembly includes a lid element having an annularly shaped peripheral portion configured to be axially aligned with and disposed between a rim of a canning container and a radially extending portion of a retainer element when the lid assembly is engaging the canning container and the retainer element is removably coupled to the canning container. An annularly shaped sealing element is disposed on the peripheral portion of the lid element and is configured to directly engage the rim of the canning container when the lid assembly is contacting the canning container. A plurality of projections is formed in the peripheral portion of the lid element with each of the projections forming a distally disposed surface of the peripheral portion with respect to an exterior axial direction of the lid element extending away from an interior of the canning container when the lid assembly is engaging the rim.
