Abstract

This invention relates to resealable closure systems that are useful in containers, such as those used in packaging goods. The reclosure system features cohesive layers which are bonded to each other to provide a resealable closure. The cohesive bond layers are separable to provide opening of the container and access to the interior of the container and / or contents. The cohesive layers have low blocking characteristics. The reclosure systems are useful for flexible packaging, such as polymeric film and cloth packages, and rigid packaging, such as fiberboard, cardboard, paper, and polymeric foam. The reclosure systems may be opened and resealed multiple times. The closure system is resistance to contamination by oils, debris, solvents, and water. The reclosure is cold sealable with finger pressure.

Description

[0001] This application claims the priority to provisional application Ser. No. 60 / 493,090 filed on Aug. 6, 2003, the content of which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION

[0002] This invention relates to reclosure systems for containers. The reclosure system comprises at least one cohesive reclosure that provides for the ability of the containers to be opened and closed multiple times. BACKGROUND OF THE INVENTION

[0003] Product packaging having reclosure mechanisms are often employed for packaging products in applications where the consumer may wish to remove only a portion of the product and to reclose the package. Particularly with baked goods, which readily dry out if left exposed to the atmosphere, there is a significant interest on the part of the product manufacturers for easily and inexpensively produced packaging that can be repeatedly opened and reclosed. Flexible packaging produced from flexible sheet materials are generally favored f...
