A slider for a slide fastener in which the slider is attached to fastener chains is provided. The slider includes a first member and a second member. The first member includes an upper blade, a lower blade, a guide post connected between the upper blade and the lower blade, and a connecting post protruding from the upper blade. The second member includes a first arm and a second arm separated from each other, is attached to the first member by the first arm and the second arm, and is configured to rotate along an upper-lower direction relative to the first member and around a fulcrum provided on the upper blade or the lower blade. The first member or the second member is provided with a flange. Three or more fit sections are formed between the first member and the second member.

A bungee bead apparatus includes a bead and elastic cord with first and second ends fixedly secured in proximity to, or in contact with, each other at one end of the bead to form a loop. A circumferential recess formed between first and second sides of the bead extends from the bead's first end to its second end, having a cross-sectional height and width to receive the loop of the elastic cord therethrough. The orifice extends at an acute angle, positioned midway between the bead's first and second sides, and begins at the bead's first end in proximity to the first side, and transects the circumferential recess at its second end. The circumferential recess is annular with a depth of about one-half the diameter of the cylindrical elastic cord to receive only a portion therein. The recess and orifice permit two (or more) such apparatus to be linked together.

A zipping apparatus includes a zipper, a first connecting portion, a first channel, and a first rod. The zipper extending in a parallel axis includes crosslinking teeth and a tab movably coupled to the crosslinking teeth. The tab is configured to open and close the zipper. The first connecting portion is coupled to the zipper and extends in the parallel axis. The first channel is disposed along the first connecting portion and extends in the parallel axis. The first rod is configured to be positioned within the first channel, such that the first rod is configured to provide structure to the zipper assembly when positioned within the first channel.

Pull tab (90) includes a pull tab main portion (92). First base (61) is sandwiched between a second base (62) and the pull tab main portion (92) to form a stack (105) in which the second base (62), the first base (61) and the pull tab main portion (92) are stacked in this order. The pull tab main portion (92) and the first base (61) are configured such that the pull tab main portion (92) moves rearward to cause rearward movement of the slider body (40) as the stack (105) is sandwiched by human fingers in its stack direction while the first insert (71) has been not fully inserted inside the slider body (40).

In at least a part of a movable range of a slider, a slider upper portion is positioned adjacent to a wall upper portion, and a slider lower portion is positioned adjacent to a wall lower portion. This prevents jamming of a cloth in the slider at both sides of the tape upper and lower surfaces.

A multi airtight type rail zipper may be attached to or installed on a flexible material, such as an envelope, for storing an object. The multi airtight type rail zipper includes a first zipper rail, a second zipper rail formed in a shape corresponding to that of the first zipper rail, and a slider provided to surround the first zipper rail and the second zipper rail such that, according to the direction of sliding movement, the first zipper rail and the second zipper rail engage with and are fastened to each other, or disengage and are unfastened from each other. The multi airtight type rail zipper can improve the sealing force by the more stable fastening structure.

A zipper includes a tape body including two zipper tapes each having an inner edge with a row of teeth. A stop includes a first end connected to distal ends of the rows of teeth and receives two first conductive plates. An end of one of the two first conductive plates is electrically connected to an electrode of at least one light-emitting element. A power connecting portion is electrically connected to another of the two first conductive plates and another electrode of the at least one light-emitting element. A slider is slidably disposed on the rows of teeth for engaging or disengaging the rows of teeth. The slider includes a second conductive plate configured to simultaneously contact with the two first conductive plates, causing electrical conduction to activate the at least one light-emitting element to emit light. A container with the zipper is also provided.
