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.

A container, comprising a body having a closed lower portion, a middle portion adapted for storing contents, and a closeable open upper portion; and an item, such as a strip of paper, adapted to cooperate with the closeable open upper portion, wherein the item includes identifying indicia regarding the stored contents, and wherein the item cooperates with the closeable upper portion to make the closeable upper portion tamper-resistant after closure thereof.

A container having a body with a closed lower portion, a middle portion adapted for storing contents, and a closeable upper portion, wherein a plurality of immediately adjacent circular apertures have been formed in and through the material of the closable upper portion; and an item adapted to cooperate with the closeable open upper portion, wherein the item includes identifying indicia regarding the stored contents, wherein the item cooperates with the closeable upper portion to make the closeable upper portion tamper-resistant after closure thereof, wherein the item includes a strip of paper or similar material having adhesive deposited on one side thereof, and wherein when the strip of paper is applied to the closable upper portion by folding the adhesive-bearing side of the strip over onto itself, the adhesive passes through each aperture in the plurality of immediately adjacent apertures causing the strip of paper to stick to itself.

An improved bag for carrying a plurality of items and methods of using the same are disclosed herein. In a preferred embodiment, the bag is made from a biodegradable material, such as paper, and the bag is used for carrying ice. The paper of the bag may be coated in a biodegradable wax laminate, such as a plant-based or animal-based wax, for increased water resistivity.

A food storage bag is described. The food storage bag includes a bag portion configured to receive contents for storage and a frame portion configured fasten close the bag portion with an airtight seal. The bag portion includes a retaining structure configured to securely attach the bag portion to the frame portion. The frame portion is configured to securely hold opposing interior sides of the bag portion in order to form the airtight seal. The bag portion may be made of silicone and the frame portion may be made of Polypropylene plastic.

A system is configured to produce a series of printed clips. The system includes a source of web material, a cutting station, a drive assembly and a printing station. The web material is configured to pass through the system in a machine direction. The cutting station is configured to cut a first portion of the web material into at least a first clip, index the first portion after cutting, and sequentially cut a second portion of the web material into at least a second clip. Cut portions of the web material exit the cutting station in a free loop. A drive assembly is configured to feed web material of the free loop through the printing station at a web speed. The printing station is configured to print indicia on a first surface of the cut portions of the web material.

A sealing clip comprises: a body part provided such that an inner space is formed by a pair of members mutually connected by a coupling means; a handle part formed at one end of the body part; and an elastic part provided on inner circumferential surfaces of the pair of members of the body part. The elastic part comprises: first and second elastic portions respectively provided on upper and lower parts of an inner circumferential surface of a first member of the body part; third and fourth elastic portions respectively provided on upper and lower parts of an inner circumferential surface of a second member of the body part. The first and third elastic portions provide an upper engagement structure, the second and fourth elastic portions provide a lower engagement structure, and engagement interfaces of the upper and lower engagement structures do not coincide with each other.

A connection mechanism including a plurality of microstructure features. The connection mechanism includes a first strip, with a plurality of protrusions extending from the first strip, and a second strip, with a plurality of protrusions extending from the second strip. The protrusions define grooves between adjacent protrusions. A pressure sensitive adhesive is provided in at least some of the grooves. When the first and second strips are brought together, the protrusions from one strip are received in the grooves of the other, and some of the protrusions contact the pressure sensitive adhesive, thereby connecting the first and second strips. The connection mechanism can be used as a closure mechanism for a plastic storage bag.

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.
