Abstract: A slider device having contoured top and sidewalls is disclosed for use with a resealable package. In a first embodiment, the slider device includes an engagement structure for engaging and interlocking first and second closure profiles of a resealable closure mechanism. The engagement structure includes a first protrusion and a second protrusion depending from the top wall of the slider device for engaging first and second closure profiles of a resealable closure mechanism. The first and second protrusions selectively open and close the resealable closure mechanism as the slider device is moved from a first position to a second position. In a second embodiment, a slider device is disclosed having first and second slide channels that engage first and second closure profiles. The first and second slide channels selectively open and close the resealable closure mechanism as the slider device is moved from a first position to a second position. Methods of assembling and operation are described.

Abstract: A slider device for use with a resealable package includes a top wall with first and second ends, a spreader depending from the top wall, a first sidewall, a second sidewall, a first hook construction extending from the first sidewall, a second hook construction extending from the second sidewall, and a guide construction. The first and second hook constructions have sloped or tapered surfaces that facilitate mounting of the slider device on a reclosable closure construction, such as a zipper arrangement. Methods of assembling and operation are described.

Abstract: A method of making packages having a reclosable zipper closure encased in a tamper-evident structure, and the packages made thereby. The method includes providing a package having an interior defined by a bottom seam and side seams. The side seams are present as a body seam and a tamper-evident structure seam; there is no side seam present across the zipper closure. The lack of a side seam present across the zipper closure facilitate removal of the tamper-evident structure. A slider device may be present on the packages to facilitate mating and unmating of the zipper closure.

Abstract: A filtration face mask 10 that comprises a mask body 20 and a band 30. The mask body is adapted to cover the nose and mouth of a wearer and that comprises polyolefin containing fibers. The band 30 comprises an elastic constituent and a fibrous thermoplastic constituent. The fibrous thermoplastic constituent has a melting point of about 250° C. or less and is a polyolefin or a substituted polyolefin. The band is attached to the mask body by heat and pressure at securement points 23.
