Method and apparatus for placing a product in a flexible recloseable container
View Patent ↗An invention 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 strips.
1. A method of using a package, the package comprising a surrounding wall defining a package interior, a zipper closure having a slider device mounted thereon, the zipper closure comprising a first interlocking closure profile having a first sealing flange and a second interlocking closure profile having a second sealing flange, a first tamper evident-structure encasing the slider device, and a second tamper evident-structure encasing the sealing flanges, the surrounding wall being attached to the second tamper evident-structure; the method comprising:
(a) penetrating the first tamper evident-structure to expose the slider device;
(b) moving the slider device along the zipper closure to unmate the first and second interlocking closure profiles; and
(c) penetrating the second tamper evident-structure to gain access to the package interior.
2. The method of claim 1 wherein said moving is after said penetrating the first tamper evident-structure.
3. A flexible, reclosable package comprising:
(a) a surrounding wall defining a package interior;
(b) a zipper closure comprising 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, the zipper closure providing access to the package interior;
(c) 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;
(d) a first tamper evident-structure encasing the slider device; and
(e) a second tamper evident-structure encasing the sealing flanges of the closure profiles, the second tamper evident-structure positioned between the package interior and the closure profiles, the surrounding wall being sealed to the second tamper evident-structure.
4. The package of claim 3 wherein said first tamper evident-structure encases the distal ends of said closure profiles.
