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.

The present disclosure relates to a track zipper and a connecting structure having a track zipper. The track zipper includes a first track, a second track, and a zipper core connecting the first and second tracks. The first track and a first side of the zipper core are provided with a first slidably connecting structure. The second track and a second side of the zipper core are provided with a second slidably connecting structure. When the track zipper is in a closed position, the zipper core is positioned between the first and second tracks and holds the first and second tracks together. The track zipper of the present disclosure is advantageous in that it can prevent foreign material from being caught by the zipper, and that it has a much stronger bearing capacity.

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.

A closure mechanism includes a first elongate closure member having a series of spaced features disposed along an entire length of the first elongate closure member. A second elongate closure member includes a series of spaced features disposed along an entire length of the second elongate closure member. The second elongate closure member sealingly engages the first elongate closure member. A slider interacts with (i) the series of spaced features on the first elongate closure member to produce a first feedback at a first frequency, and (ii) the series of spaced features on the second elongate closure member to produce a second feedback at a second frequency. The first feedback at the first frequency differs from the second feedback at the second frequency.

A closure mechanism includes a first elongate closure member having a series of regularly spaced features disposed along an entire length of the first elongate closure member. The series of regularly spaced features includes a plurality of vertically extending elongate features on an outer surface of the first closure member. The vertically extending elongate features are spaced apart along the entire length of the first closure member in alternating and repeating distances. A second elongate closure member includes a series of regularly spaced features disposed along an entire length of the second closure member and sealingly engages the first closure member. A slider interacts with (i) the series of regularly spaced features on the first elongate closure member to produce a first feedback at a first frequency, and (ii) the series of regularly spaced features on the second elongate closure member to produce a second feedback at a second frequency.

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 bag including opposing panels, a closed bottom and a reclosable top. The bag further includes a closure assembly along the reclosable top and a handle assembly joined to one of the panels.
