Appl. No.:

11/589449

Inventors:

Paul Adam Sprague - Kiel WI, US
Peter John Boulanger - Appleton WI, US

Assignee:

Reynolds Consumer Products, Inc. - Richmond VA

International Classification:

B65D 33/16
B65D 33/25
A44B 19/16
A44B 19/00

US Classification:

24399, 24 305 R, 2458512, 383 64

Abstract:

A reclosable tamper-evident package is opened and closed repeatedly by opening and closing a first closure of a package, and when it is desired to close the package and provide an indication of further opening, a second closure is closed that cannot readily be opened. The tamper evident package has a closure assembly that includes a zipper closure arrangement with a slider device. In one embodiment, the slider device is movable between a first axial position and a second axial position. When the slider device is in the first axial position, moving the slider device laterally along the zipper closure arrangement in a first direction closes the first closure. When the slider device is in the second axial position, moving the slider device laterally along the zipper closure arrangement in a first direction closes both the first closure and the second closure. A method of using a package includes grasping a slider device and moving the slider device laterally in a first direction to close the first closure and to permanently close the second closure.

International Classification:

B65D033/16

US Classification:

383/061200, 383/204000, 383/211000

Abstract:

A reclosable package that seals an enclosed product and allows the product to be subjected to a retort procedure to cook the product while the product is in the package. The reclosable package is formed from a polypropylene film and includes a zipper closure including a pair of mating closure profiles both formed from a polypropylene material. One of the male or female closure profiles includes a sealing flange having a layer of sealant such that the sealing flange provides a seal for the package below the interaction between the closure profiles. This seal prevents the product from migrating through the profile member during the retort procedure and prior to the package being opened for the first time.
