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.

A reclosable package comprises a first panel having first and second side sections and a second panel having first and second side sections. The first panel opposes the second panel and is joined to the second panel along the first and second side sections. A bottom extends between the first and second side sections of the first and second panels with the first and second panels joined to each other. A mouth is disposed opposite the bottom and extends between the first and second side sections of the first second panels. A closure member extends along the mouth, with the closure member including a first fin joined to the first panel and second fin joined to the second panel. A sealing member having a first and second ends is disposed proximate the mouth. The ends of the sealing member can be attached to the fin or panel such that at least one of the first end or second ends of the sealing member is attached with peelable seal.

A slider for a zipper closure includes a separator plow that is positionable between interlocking tracks of the zipper closure to open the zipper closure by pivoting an opening end of the slider in a direction toward a notch to position the plow between the interlocking closures. The slider can be disengaged by pivoting the slider so that the plow is outside of the interlocking tracks.

A storage bag has first and second side surfaces, and a sealable and an unsealable opening. A bottom end of the bag is movable between a flat configuration with the first and second side surfaces positioned adjacent to each other, and an expanded configuration with the first and second side surfaces being spaced from each other. Shape retaining strips are provided adjacent to the opening that can maintain the shape of the opening. The shape retaining strips are capable of maintaining the opening of the bag such that a distance between the first and second side surfaces at the top end of the bag is about equal to the distance between the first and second side surfaces at the bottom end of the bag.

A slider zipper closure system includes a zipper closure with complementary profiles of opposing tracks for interlocking and unlocking; the closure a first end stop and a second end stop positioned opposite ends of the closure. A slider device is positioned on the zipper closure between and engaging the first end stop and second end stop to selectively: (i) unlock the complementary profiles as the slider device is moved along the tracks in an opening direction; and (ii) interlock the complementary profiles as the slider device is moved along the tracks in a closing direction. The slider device has a first end stop engagement surface positioned inboard from the closing end and adapted to strike the first end stop.

A child resistant slider includes a top member and a pair of spaced legs depending from the top member. At least a first leg of the spaced legs has a first tang projecting laterally away from a remaining portion of the first leg and a remaining portion of the slider. The first tang has a separator plow. The tang can be movable to move the first plow into a position to separate interlocked male and female tracks of a zipper closure. In other examples, both legs include a projecting tang having a separator plow.

An apparatus and method for operably mounting a slider onto a recloseable plastic zipper closure includes a rotor having at least one slider-engaging shoulder; an insertion wedge adjacent to the rotor and sized to slidably accommodate the slider for mounting onto a zipper closure; and a zipper guide member adjacent to the rotor and adjacent to the insertion wedge for guiding and holding a zipper closure while the slider is mounted thereon. The insertion wedge will have a leading edge and a trailing edge and increase in thickness from the leading edge to the trailing edge. The apparatus can be vertically oriented or horizontally oriented.
