A bag closure system includes a bag having a top end and a bottom end, and an elastic band having an anchored end and a free end, where the anchored end is fixed proximate the bottom end of the bag. The free end of the elastic band is configured to be stretched around the top end and the bottom end of the bag while the anchored end remains fixed proximate to the bottom end. The elastic band may be made of natural rubber and a permanent adhesive or thermal bond may be used to fix the anchored end proximate the bottom end of the bag. In addition, a visual fold line may be provided diagonally at each of the corners of the bag, and a visual first lateral fold line and a spaced apart visual second lateral fold line provided on the body of the bag.

Disclosed are flexible fluid reservoirs including a front sheet and a back sheet, each comprising a four-layer insulated wall. The four-layer insulated wall includes an interior layer and an exterior layer, and a metallic film layer and an insulation layer disposed between the interior layer and the exterior layer where the metallic film layer is oriented toward the exterior layer and the insulation layer is oriented toward the interior layer. One or more of the interior or exterior layers can be a metallocene modified polyethylene film. The metallic film layer can be aluminum coated polyethylene terephthalate resin. The insulation layer can be a foam layer comprising closed cell polyethylene resin. The four-layer insulated wall can resist or limit temperature changes of a fluid disposed within the reservoir for a period of time. The insulated fluid reservoirs can include closure mechanisms for sealing an upper opening of the reservoir.

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 sack includes a flexible sack body and a mouth that includes two separable lips that form a mouth opening when the lips are separated from one another, and that close the opening when the lips are adjacent to one another. Closing structure is configured to enable a separating force that is applied to the lips to separate the lips from one another to form the mouth opening, and to bring the lips adjacent to one another to close the mouth opening in the absence of the applied separating force.

The present invention relates to a scoop (1) comprising a bowl (2) and a handle connected to the bowl (2) and comprising a clip (6). The clip (6) can be used for re-closing a bag containing a product to be dosed by the bowl (2). The clip (6) is delimited by a free edge (9), and there is a gap (12) between the free edge (9) of the clip (6) and handle edges (10) of regions of the handle (3) surrounding the clip (6). At least a part of the clip edge (9) and at least a part of the handle edges (10) delimiting the gap (12) are provided with teeth (13) in the form of teeth-shaped protrusions. The teeth (13) at the clip edge (9) and the teeth (13) at a proximate handle edge (10), respectively, are arranged at alternating positions along a longitudinal extension of the gap (12).

A watertight bag includes a bag body, a closure retainer and a fastener. The bag body has an opening facing upward at a top edge thereof. The top edge of the bag body is to be folded over to turn the opening upside-down. The closure retainer is disposed at the top edge of the bag body and includes first and second strip members that are respectively disposed at opposite sides of the bag body for sealing the opening of the bag body. The fastener is disposed on the bag body for fastening the closure retainer in position when the top edge of the bag body with the closure retainer thereon is folded over and turn the opening of the bag body upside-down.

A handled shipping bag or sack is described that is capable of manufacture without requiring registration of the handle to a width of the bag. The shipping bag includes a cover tape having perforations particularly well suited for finger holds of a user that center the users hand relative to the width of the bag without requiring a registration of the finger holds relative to the bag during the manufacture of the bag.

A multi-cavity scoop with a bag clip. The scoop has two ends, each with a different volume for measuring goods. The clip portion of the device can then be used to seal the bag and retain the scoop in a convenient location with the goods to be distributed with the scoops. The device could include even more scoops of any necessary volume or shape. The clip could include a spring for clamping down onto the packaging of the goods to be distributed with the scoops.

A bag includes a first sidewall, a second opposing sidewall, and a foldable base. The foldable base is coupled to the first sidewall and the second side wall. The foldable base includes a first rigid panel coupled to a second rigid panel such that the foldable base is configured to fold from a generally flat configuration to a folded configuration, thereby converting the bag from an expanded configuration to a collapsed configuration.

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.
