A tearing guide strip 23 is integrated with a base part 21a or 21b of at least one of a male member 2a and a female member 2b constituting a zipper 2 in a peelable manner to improve the tearing unsealing ability of a zipper-equipped bag provided with an interlocking type zipper enabling resealing and unsealing after the bag is unsealed.

A hunting blind, components thereof, and associated methods. The blind includes a window or door comprising a closure that when open defines an opening for seeing out of the blind and/or providing ingress and egress for an interior of the blind. The closure comprises first and second closure strips and a slider movable along the closure strips to open and close the opening. The first closure strip includes a first rib having a longitudinal axis extending along a length of the first closure strip. The second closure strip includes a first channel having a longitudinal axis extending lengthwise of the second closure strip.

The disclosure pertains to powder-resistant profiles for zippers or reclosures, such as may be used for reclosable packages. A first profile includes a first upper interlocking profile and a first lower interlocking profile, The second profile includes a second upper interlocking profile and a second lower interlocking profile. The first upper and lower interlocking profiles may include male elements while the second upper and lower interlocking profiles may include complementary female elements. A first central area is termed between the first upper and lower interlocking profiles and a second central area is formed between the second upper and lower interlocking profiles. The first and second central areas include respective first and second series of apertures through the male elements to allow powder otherwise trapped between the first and second profiles to escape or exit therethrough.

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.

The present disclosure relates to a leak-resistant slider zipper. The zipper typically includes end seals at the opening and closing ends of the zipper, an upper and a lower set of interlocking elements, first and second upper flanges above the upper interlocking elements having no gaps or cut-outs therein, and first and second lower flanges below the lower interlocking elements, one of the lower flanges being folded back on itself, and a slider.

A waterproof, open-end zipper includes a first zipper tape with a first engagement rail unit, a second zipper tape with a second engagement rail unit, a zipper slider slidable to force the first engagement rail unit and the second engagement rail unit into engagement with each other or separate them from each other, a box located at one end of the first engagement rail unit for receiving one end of the second engagement rail unit, a locating rod fixedly located at the first engagement rail unit, and a locating hole located at the second engagement rail unit for receiving the locating rod after insertion of the second engagement rail unit into the box to prohibit relative displacement between the first and second zipper tapes.
