Disclosed fluid reservoirs include closure mechanisms for sealing an upper opening of the reservoir. The reservoir can have plates adjacent the upper opening. When the upper end of the reservoir is folded, the plates can be positioned on opposite sides, and a closure frame can be slid over the plates to pressure them together. The plates can have pins that engage with slots in the closure frame, and a separate closure lock can be slid over the end of the closure frame to prevent the pins from exiting the slots. The plates can also bias the opening open when the closure is not engaged. Also disclosed are flexible fluid reservoirs that include structural elements, such as baffles, that help retain a desired shape of the reservoir when filled or empty. Some baffles can be elastically deformable to allow flattening and expansion of the bladder while biasing toward a neutral position.

A food bag closure assembly includes a clip that has a pair of jaws being biased against each other for closing an opened food bag. A gas unit is provided that stores an inert gas and the gas unit is integrated into the clip. The gas unit is in fluid communication with an interior of the food bag when the clip is positioned on the food bag. Moreover, the gas unit is actuated to release a pre-determined volume of the inert gas each time the clip is closed. In this way the gas unit injects the inert gas into the food bag for extending the shelf life of food contained in the food bag.

The food delivery container closure is a clip. The food delivery container closure is a single use structure. The food delivery container closure is configured for use with packaging. The food delivery container closure permanently secures the packaging in the closed position. The food delivery container closure is a sacrificial structure. The food delivery container closure is damaged when the food delivery container closure is removed from the packaging. The food delivery container closure includes a first arm, a second arm, a torsion structure, and a release structure. The torsion structure attaches the first arm to the second arm to form a clip used to secure the packaging. The first arm and the second arm permanently attach to the packaging. The release structure damages the torsion structure such that the first arm and the second arm detach, allowing the packaging to open.

A carrying device for receiving goods, including a carrying wall which has a front wall and a rear wall, is arrangeable between a closed state and an open state, at least partially forwardly, downwardly and rearwardly delimits a carrying volume for receiving the goods in the closed state, and downwardly opens up the carrying volume in the open state. The carrying device includes a closing device for releasably connecting the front wall to the rear wall in the closed state and an actuating device, connected to the closing device, for releasing the connection between the front wall and the rear wall from the closed state, having an actuating structure arranged at a spacing from the closing device and a transmission structure acting between the actuating device and the closing device. The transmission structure is formed in a flexible manner.

The present disclosure relates to other garbage and kitchen garbage classification throwing technologies in the technical field of garbage classification, in particular to a garbage bag. The garbage bag comprises a bag body, wherein the bag body is of a hollow structure with an opening in the top, a pouring opening is formed in the bottom of the bag body, and the bag body is formed in a folding mode so that the bottom of the bag body is fixed to one side of the bag body. When garbage in the bag body needs to be poured out, a point-breaking line or glue is torn off, the bottom of the bag body is separated from one side of the bag body, and after the bottom of the bag body naturally droops, the garbage is poured downwards from the point-breaking line under the gravity of the garbage to be separated from the bag body. Therefore, the garbage in the garbage bag body can be completely poured out without opening bound handles or turning over the garbage bag body or puncturing the garbage bag with a tool, the action is simple and convenient, safety and reliability are achieved, and garbage throwing workers are prevented from being stained.

A system and method for sealing containers such as bags using a sealing apparatus including handles connected to sealing strips, such as magnetic strips, for pulling apart the sealing strips to allow insertion of the container, which may be a bag holding a substance such as food or non-food items. The sealing apparatus can be provided as a separate device, or made integral with the container.

A collapsible and reusable food storage container is formed from a single, foldable sheet having a receptacle portion and a lid portion. The foldable sheet is formed from a plurality of planar panels positioned adjacent to one another, with a foldable seam spanning an offset formed between sets of the adjacent planar panels. In use, the foldable sheet may be repeatedly transitioned between a collapsed configuration in which the foldable sheet is folded about the foldable seam into a flat packet and an assembled configuration in which the foldable sheet is unfolded into a receptacle and an attached lid for securely storing a portion of food. The planar panels may be formed of polypropylene, while the foldable seam may be formed of silicone that is overlaid into the offset between adjacent panels and sonically welded to the edges of the adjacent planar panels. Other embodiments are also disclosed.

The present invention provides a sealing closure made of flexible magnetic strips with a non-uniform thickness, which provide an improved interlocked seal in addition to a magnetic seal. The sealing closure has strips with at least one guide that aligns automatically with another strip when the two strips are brought together to create a more secure sealing closure.

Disclosed fluid reservoirs include a 3-D formed first sheet and a 3-D formed second sheet. The 3-D formed first sheet and the 3-D formed second sheet are sealed together at least partially around respective perimeter edges thereof to define an internal space for fluid storage, There is a first opening defined between the 3-D formed first sheet and the 3-D formed second sheet at a first end of the fluid reservoir. The first opening is configured for filling the fluid reservoir with fluid. There is a second opening defined between the 3-D formed first sheet and the 3-D formed second sheet at a second end of the fluid reservoir opposite the first end. The second opening has a fluid exit port configured for allowing fluid to exit the fluid reservoir. The reservoir can include an optional baffle that is coupled to the 3-D formed first and second sheets.
