example 1

[0143]Temperature indicating lid composition: A universal lid composition was prepared using VERSAFLEX CL2000X, a thermo polymer elastomer (GLS Corp.). The resin was extruded using a 1 inch 3 zone extruder set at 250° F., 390° F., and 370° F. for zones 1, 2, and 3 respectively. A dried finely ground thermochromic powder (10° C. vermillian, blue, black, yellow, turquoise, pink, brilliant green, brown, or other available colors from Matsui Corp.) was added and blended at 1.5% by weigh and coated onto the CL2000X resin. The resin / composition was extruded at 90 rpm into elongated ingots.

example 2

[0144]Compression molded universal lid: The temperature indicating composition in ingot form in Example 1 above was compression molded using a pre-machined aluminum molded (6061) into pre-determined lid shapes comprising a top surface (0.06 inch thick and an undercut edge band). The undercut edge band was 0.125 inches thick and 0.75 inches tall.

example 3

[0145]Temperature indication and utility of a universal lid: The universal lid molded in Example 2 above was stretched over a variety of container types storing liquids, perishables, food types, or other substances. The lid was compressed in the middle to create permanent vacuum for enhanced storage conditions. The lid transitioned from a light translucent clear color to a dark temperature indicating color upon cooling to 10° C. The lid held its vacuum at room temperature, refrigerator temperature, and sub-zero temperatures.

Abstract

Universal lids, as well as methods of making and using the same, are provided. Universal lids of the invention are compliant and to accommodate multiple different sizes of containers, such that they may effectively cover at least two different containers that differ from each other in terms of size of the opening of the container. In certain embodiments, the lids are fabricated from a compliant material. In certain embodiments, the lids include an undercut. Embodiments of the lids include one or more of a detector component, e.g., for detecting temperature, time, etc.; a gas permeable component, e.g., for allowing certain gases to pass into and out of the sealed container; etc.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Pursuant to 35 U.S.C. § 119 (e), this application claims priority to the filing date of U.S. Provisional Patent Application Ser. No. 61 / 027,026 filed Feb. 7, 2008, the disclosure of which application is herein incorporated by reference.INTRODUCTION[0002]It is often desirable to employ reusable containers in a variety of applications, including food preparation and storage, as well as storage of non-food items. When using such containers, it is often desirable to employ a lid, i.e., a cover, for the container, where the lid serves to keep the item in the container, and can be configured to maintain freshness, or otherwise protect the contained item.[0003]However, an effective lid must be matched to the container to work. As such, lids must be configured to a particular container in order to be used with that container.[0004]Because of the multitude of different types of containers having different dimensions, this makes providing a lid for...
