The first and second locking tabs each have a lateral portion and a locking portion. The lateral portion has an inner surface and an outer surface and extends outwardly from the sidewall in a direction that is generally parallel to the top surface of the cover portion. The locking portion extends downwardly and inwardly at an angle from the lateral portion. A locking protuberance is disposed on the inner surface of the locking portion, and an elongate aperture that terminates proximate the locking protuberance is disposed in a portion of the lateral portion and the locking portion.

A buckling structure includes a cover and a box, wherein the cover and box are each made of paper, plastic, or a combination thereof. In one embodiment, the box includes a box body and a straight line part extending out of an edge of the box body; and the lid is configured to cover the box and includes a lid wall extending out of an edge of the lid body, and a flange arranged on an inner side wall of the lid wall, wherein the flange and the lid body are spaced apart, and wherein in a cross section along a central axis of the box body, the angle between the straight line part and the central axis is smaller than or equal to 90 degrees, wherein in the cross section along the central axis of the box body, the flange comprises a section of lead-in part, a section of smooth part connected to the lead-in part, and a section of buckling part connected to the smooth part, the maximum diameter of the straight line part being greater than or equal to the minimum diameter of the lid wall, the buckling part is arc-shaped and has a central angle that is greater than 90 degrees, and when the lid is disposed over and fitted to the box, the straight line part is configured to be clamped between the buckling part and the lid body.

A snap-fitting structure comprising a container and cover each made of paper, plastic, or a combination of both. In one embodiment, the cover includes a cover bottom and a cover wall extending out of an edge of the cover bottom, wherein a flange is disposed on an inner side wall of the cover wall, and the flange and the cover bottom are arranged at an interval. In this embodiment, the container may include a container body and a clamping portion extending out of an edge of the container body, the clamping portion comprising a connecting portion connected to the container body and a clamp ring extending out of the connecting portion. In a cross section along a central axis of the container body, the angle between a contour line of the connecting portion and the central axis of the container body is an acute angle and a contour line of the clamp ring is parallel to the central axis of the container body. Further, an outer diameter of the clamp ring is equivalent to an inner diameter of the cover wall, and the clamp ring is capable of being flexibly positioned between the flange and the cover bottom when the cover is disposed over and fitted to the container.

A container system having a base and a lid. The base has a bottom and one or more sidewalls extending from the bottom to define an interior volume, the base having a rim at a peripheral edge of the one or more sidewalls, the rim defining a first engagement region. The system also has a lid having a peripheral outer rim defining a second engagement region, the first and second engagement regions dimensioned to releasably engage with each other. The lid has a hinged region having a first hinge about which the lid folds as a first part of the lid is lifted from the base to disengage portions of the first and second engagement regions from one another, to provide access to the interior volume of the base while a second part of the lid on an opposite side of the hinge remains secured and attached to the base.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider comprises one or more engagement features for selectively engaging with the storage container, the storage container further having a retainer lid configured to retain a divider within an engagement surface of the storage container.

Disclosed are assemblies of inverted cheesecake products comprising first and second stacked products, wherein each product includes a bottom protrusion configured to lock into an upwardly-opening recess of a product therebeneath, providing secure locking engagement without adversely affecting container stability or product accessibility to an unacceptable degree. A sleeve constrains the products against destacking while permitting locking of products in one assembly with those in another assembly. A topping layer may be filled at the bottom of a base cup, covered by a filling layer, and a disassembled crust may be sealed in an overcap interior to avoid moisture migration thereto prior to use.

A household tissue paper container includes a container body that is configured to store household tissue paper therein and has a take-out portion having an outlet through which the household tissue paper is taken out; and an open/close lid that is pivotably attached to the container body and closes the outlet. The outlet is formed at a swelling portion having a substantially spherical raised shape in the take-out portion. The outlet has a protruding piece that is protruding from a front edge of the outlet toward a rear where the open/close lid is attached to the container body.

In an embodiment, the invention comprises a container apparatus with a lateral stability rail system. At least one rail extends within the lid portion and at least one track extends through the base portion. The rail terminates in a tooth and the track terminates in a pocket. When the container is in a hingedly closed position, the at least one rail nests within the at least one track and the at least one tooth nests within the at least one pocket.

A container with a security lock is provided. The container has a top unit and a bottom unit. The bottom unit may have a first side and a second side wherein the first side and the second side each have a compressible tab. The top unit may have a first opening and a second opening wherein the first opening and the second opening receive a portion of the compression tabs when the top unit is locked to the bottom unit.
