Embodiment Construction

[0023]FIGS. 1A and 1B illustrate a package 10 having a tray 12 and the top sheet 14 (or “top cover”). The tray 12 has a well 16 in which contents can be placed and a peripheral flange 18 extending around the well 16. The package may include a peg hole 19 for receiving a peg from which the package 10 may hang in a retail store.

[0024] To gain access to the contents located within the well 16, a fastener 20 is located along the top portion of the peripheral flange 18. As is known in the art, the fastener 20 includes first and second interlocking members that can be manipulated to open and close the package 10. The fastener 20 also includes fins extending downwardly from the interlocking members. In this package 10, one fin is attached to the top sheet 14 while the other fin is attached to the tray 12. Preferably, the fastener 20 includes a slider 22 that allows the user to more easily open and close the interlocking members of the fastener 20. The fastener 20 also includes a sealed no...

Abstract

A reclosable package includes a tray, a top sheet, and a fastener. The tray has a well for receiving contents and a peripheral flange surrounding the well. The top sheet is attached to the peripheral flange. The fastener has two interlocking members, one attached to the peripheral flange and the other attached to the top sheet. A tamper-evident feature located on the package prevents access to the fastener and is connected thereto by one or two lines of weaknesses. In one embodiment with one or two lines of weakness in the top sheet, the fastener remains adjacent to the tray's peripheral flange, which is intact after the tamper-evident feature is removed by tearing along these lines of weakness. In a second embodiment with two lines of weakness, the tamper-evident feature, comprised of portions of the peripheral flange and the top sheet, is torn from the package along both lines of weakness.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a Divisional of U.S. patent application Ser. No. 10 / 215,052 filed on Aug. 8, 2002, the contents of which are expressly incorporated by reference herein in its entirety.FIELD OF THE INVENTION [0002] The present invention relates to reclosable packages and, in particular, to packages that have a formed tray with a flexible cover over the tray. BACKGROUND OF THE INVENTION [0003] Plastic packages are popular for storing food products and other items. Reclosable packages that can be securely closed and reopened are particularly popular due to their ability to maintain freshness of the food stored in the package and to minimize leakage to and from the package. Thus, reclosable packages are very common, especially in the food industry. [0004] Reclosable packages are typically made to be reclosable via the use of a reclosable feature, such as a resealable adhesive seal or a reclosable zipper. Reclosable zippers can be opened...
