Embodiment Construction

[0030] Provided herein are examples of perforated shrink-wrap sleeves and containers with perforated shrink-wrap sleeves configured to provide easy partial removal, tamper evidence, and product identification, even for irregularly shaped and asymmetrical container.

[0031] In general, the presented embodiments show cost-effective and easy-to-open features for the consumer to gain full product access. As described, the proposed embodiments can provide a printing surface to provide graphics and other types of printed information on the shrink wrap film, which can be transparent, translucent, opaque, or variations / combination. Metallic inks are also available to provide silver or metallic shades. To accommodate container shape irregularities, the ratio of maximum to minimum shrinkage should be at least 2:1. It should be noted that various product container sizes are possible as long as the shrink wrap can be maintained thereon even after part of the film strip is removed. P...

Abstract

A container (10) having a container body that can have a circumference / perimeter variation along a vertical axis, a bottom surface (12), and a container opening having a top surface (14), an axially oriented shrink wrap sleeve (30) covering a portion of the body of the container (10) having a circumference variation and the container opening, a top edge (22) of the shrink wrap sleeve (30) allowing the top surface (14) to remain exposed, and bottom edge (20) of the shrink wrap sleeve (30) allowing the bottom surface (12) to remain exposed; the shrink wrap sleeve (30) having a pair of generally vertical perforations (32) descending from the shrink wrap top edge (22) towards a circumferential perforation ring (34) oriented below the container opening. In some embodiments, the axially oriented shrink wrap sleeve (30) covering a portion of the container body circumference variation has a greater circumference at least one point between the shrink wrap top (22) (or alternately shrink wrap circumferential perforation ring) and bottom edges (20).

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application No. 61 / 374,027, filed August 16, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The proposed product and method relate to packaging, and in particular to easy-open containers with perforated shrink-wrap sleeves. Background technique [0004] It is known to use heat-shrinkable films ("shrink wrap") to seal product containers, identify container contents, and provide an indication that the container has not been opened. The use of such membranes is described in U.S. Patent No. 6,296,129 to Kawasaki and U.S. Patent No. 5,605,230 to Marino et al., the specifications of which are incorporated herein by reference . Shrink wrap applications can be economically applied to a variety of containers for a variety of products, such as food or pharmaceutical applications. [0005] Despite the advantages of heat shrinkable...
