Benefits of technology

The invention provides a series of arcuate cuts on a resealable tape or label to prevent uncontrollable tearing of the package. The cuts transfer forces more directly to the frangible areas between the cuts, making it easier to open the package. The use of a pressure-sensitive adhesive coating on a light weight, inexpensive material makes the manufacture easy and inexpensive. The resealable feature can be supplied by a simple covering resealable transparent adhesive tape.

Problems solved by technology

When the package is first opened, frangible portions of the package between the adjacent arcuate cuts are torn and distorted so that re-registration of the opposed, laterally-extending edges of the portal is not possible upon resealing.
This results in a package which is tamper-evident.

Embodiment Construction

[0023]As defined herein the terms “upward”, “downward” and “longitudinal” define the direction between the top and bottom edges of the package and the terms “lateral” and “laterally” define the direction extending between the opposing sides of the package. Referring now to FIG. 3, a pre-construction layout of the elements of one embodiment of the invention is shown. The film 31 has a piece of transparent, pressure-sensitive-adhesive reseal structure 33 affixed across it extending laterally. The adhesive structure includes a pull tab 35 that projects upward from the main body of the reseal structure 33. The adhesive on the backside of the pull tab 35 is deadened so that it may be easily grasped by the user. The reseal structure 33 extends laterally beyond fold lines 36 which define the sides of the package when constructed so that end portions 34 of the reseal structure 33 wrap around the sides of the package and the side of the structure which is coated with a pressure sensitive adh...

Abstract

A tamper-evident package utilizes a transparent resealable adhesive structure such as a tape or a label to cover the portal opening. When the package is first opened, frangible portions of the package between adjacent arcuate cuts and slits that define the portal are torn and distorted so that re-registration of the opposing laterally-extending edges of the portal upon reclosing is not possible. This results in a package which is visually tamper-evident. The tamper-evident condition can be enhanced by graphics or other printing on the front of the package in the area of the arcuate cuts and the center of the portal to make the misalignment of a resealed portal viewed through the transparent reseal structure more visually apparent. In one embodiment of the invention, a series of arcuate cuts are centered laterally and are flanked on the right and left sides by two continuous wavy slits, which together form the portal.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation application of U.S. patent application Ser. No. 15 / 696,492 entitled Tamper-Evident, tear-Open Resealable Package, filed Sep. 6, 2017, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to flexible packaging. More specifically it relates to tear-open bags or pouches which have tamper-evident resealable closures.BACKGROUND OF THE INVENTION[0003]Most often consumer food packages are made in such a way that for the consumer to access the product a tear strip at the top of the pack above the usual zipper or slider has to be torn off and thrown away. Because of the way these packages are made the bag material often tears unreliably and not straight. Sometimes it only tears part of the way and the leftover edges of film get in the way of the zipper or slider reclosing easily. Furthermore, consumers prefer not to be left holding a part of the package in their ...
