A reversible lid, the reversible lid includes a covering portion and a circumferential portion. The circumferential portion has a first part, a second part and a transverse part. The first part has a first end and a second end and extends generally parallel from the periphery of the covering portion at the first end. The transverse part extends radially outwardly transverse from the second end of the first part, and the second part extends in a same direction as the first part and is connected to the transverse part. The first part, the second part and traverse part are configured such that in a first orientation the lid covers the container with a first side of the transverse part abutting a rim of the container and in a second orientation covers the container with the second side of the transverse part abutting the rim of the container.

A flexible lid for containers provides a secure and leak-proof seal. The lid includes a top wall and a cylindrical flange forming a valve closure portion. A central plug extends from an underside of the top wall, wherein an annular channel is formed between the plug and the flange. The plug is deformable and can form a tight seal with a bottle when received within the annular channel. The flexible lid includes threads on the inner surface of the side wall for cooperating with the thread on the neck of the bottle, which is rotated to engage the threads and secure the lid to the bottle. The lid can be easily removed by unthreading from the neck and disengaging the plug to unseal the lid. In some embodiments, the plug is separable from the flange and replaced with a nipple that is inserted through an aperture in the top wall.

A lid for sealing a tumbler or other type of beverage container. The lid features a cover and a sidewall, as well as a resilient drink opening plug that is removably tethered to the cover. The cord that tethers the plug is flexible, but is pre-formed into a pair of parabolic arcs that help prevent the cord from wildly dangling or flopping into a user's face while drinking.

Coupling systems including interlocking male and female members are disclosed herein. An example apparatus includes a first coupling including a sidewall having an annular spring. The example apparatus also includes a second coupling to be coupled to the first coupling. The second coupling has an annular wall including a seal. The seal is to sealingly engage the annular spring when the second coupling is coupled to the first coupling.

A container includes a casing defining an opening and formed with a first abutting edge surrounding the opening. A cover is selectively mounted onto the casing for closing the opening, wherein the cover has a second abutting edge laterally extending therefrom and abutting against the first abutting edge when the cover closes the opening. A puller extends from the second abutting edge of the cover. A snapping device is formed between the casing and the puller. The snapping device includes a plug formed on the puller and a socket defined in the casing for receiving the plug. Two weakened portions are formed on the puller such that the puller is irreversibly curved after being lifted due to the weakened portion and the curved puller is used as a basis for easily identifying whether the container is illegally operated or not.

A food storage container including a case having an open side and forming a storage space and a case cover configured to be detachably coupled to the case so that, when coupled to the case, the case cover covers the open side of the case and seals the storage space, the case cover including a receiving portion forming a receiving space configured to accommodate a gas absorbent, and having a discharge hole between the receiving space and the storage space, a valve to open and close the discharge hole in response to a pressure inside the storage space, and a receiving portion cover configured to be detachably coupled to the receiving portion so that, when coupled to the receiving portion, the receiving portion cover seals the receiving space, wherein a gas flowing from the storage space through the discharge hole to the receiving space is adsorbed by the gas absorbent.

A storage container is provided. The container includes a receptacle and a lid connected to the receptacle by a hinge. The lid has a latch for sealing the receptacle closed. The receptacle and the lid are each made from a continuous unitary piece of material that has hinge components formed within the material.

A drinking container includes an automatically opening and closing magnetic lid. The drinking container includes a container portion, a sleeve, and a lid. The sleeve is moveable between a closed position and an open position with respect to the container portion, the sleeve including a sleeve magnet. The lid is moveable from a closed configuration to an open configuration, the lid including a lid magnet, the closed configuration of the lid sealing an access pathway to an interior of the container portion, the open configuration of the lid opening the access pathway to the interior of the container portion. In the closed position of the sleeve, a biased force holds the lid in the closed configuration. In the open position of the sleeve, the sleeve magnet and the lid magnet have a magnetic force greater than the biased force to place the lid in the open configuration.

A container includes a casing having an opening and a first abutting edge surrounding the opening. A cover is selectively mounted onto the casing for closing the opening, wherein the cover has a second abutting edge laterally extending therefrom and abutting against the first abutting edge when the cover closes the opening. A puller extends from the second abutting edge of the cover. A snapping device is formed between the casing and the puller. The snapping device includes a plug formed on the puller and a socket defined in the casing for temporarily receiving the plug and holding the plug in place. A weakened portion is formed on at least one place of the puller such that the puller is irreversibly curved after being lifted due to the weakened portion and the curved puller is used as a basis for easily identifying whether the container is illegally operated or not.

A container, that prevents an illegal operation and can be easily identified after being illegally operated, includes a bowl-shaped base and a cover selectively closing the bowl-shaped base, wherein a pre-broken structure is formed on the cover and the cover cannot be smoothly detached from the bowl-shaped base before the pre-broken structure being damaged. For the market, the salesperson easily confirms that the container has been illegally operated and the illegally operated container is replaced in time for providing fresh good to the consumers. For the consumers, the illegally operated containers can be easily confirmed and eliminated through choosing for preventing from buying unsafe or stale goods, particularly foods.
