Apparatus and methods for forming, filling, and sealing a flexible recloseable container. Both vertical and horizontal methods for placing product within the container are disclosed. The invention includes guiding a web of film which has interlocking fastener strips sealed to the web. A slider for locking and unlocking the fastener strips is placed in the correct orientation, spread apart at a pair of inner feet, and inserted over the fastener strips. The slider is positioned to close a substantial portion of the strips, and then an end stop, docking station, and corner seal are formed against a sealing plate. The slider is then repositioned, and a tamper evident seal may be placed over the fastener strip.Apparatus and methods for placing a product in a flexible recloseable container, and also for manufacturing an empty, flexible recloseable container. One method includes providing a pair of interlockable fastener strips, a web of flexible film, and a plurality of sliders, placing the sliders on the pair of interlockable fastener strips, subsequently attaching the interlockable fastener strips with attached sliders to the web of flexible film, and either placing a product within the web or providing the empty container to the consumer.

1. A method of manufacturing a reclosable package comprising a zipper closure and a slider device, the method comprising:(a) providing an extended length of a zipper closure construction, the zipper closure construction comprising: (i) a first interlocking closure profile and a second interlocking closure profile, each of the closure profiles having a distal end and a sealing flange disposed opposite the distal end; (ii) a slider device operably mounted on the zipper closure; the slider device constructed and arranged to interlock the first closure profile with the second closure profile when the slider device is moved in a first direction, and to disengage the first closure profile from the second closure profile when the slider device is moved in a second opposite direction, the slider device mounted on the distal ends of the closure profiles; (iii) a first tamper-evident structure enveloping the slider device; (iv) a second tamper-evident structure enveloping the sealing flanges of the closure profiles; (b) sealing the extended length of zipper closure to a surrounding wall; and (c) creating edges to form a package interior. 2. The method of claim 1 wherein the first tamper evident structure envelopes the distal ends of the closure profiles.3. An extended length of a zipper closure comprising:(a) a first interlocking closure profile and a second interlocking closure profile, each of the closure profiles having a distal end and a sealing flange positioned opposite the distal end; (b) a slider device operably mounted on the first and second closure profiles; the slider device constructed and arranged to interlock the first closure profile with the second closure profile when the slider device is moved in a first direction, and to disengage the first closure profile from the second closure profile when the slider device is moved in a second opposite direction, the slider device mounted on the distal ends of the closure profiles; and (c) an envelope encasing the first and second closure profiles and the slider device mounted thereon, the envelope comprising: (i) a first tamper-evident structure positioned over the slider device, the first tamper evident-structure connected to the sealing flanges; and (ii) a second tamper-evident structure connected to the sealing flanges. 4. The zipper closure of claim 3 wherein the first tamper evident structure is positioned over the distal ends of the closure profile.
