Insulating/protective covering for a container

Abstract

An insulating wrap for adding to containers to prevent heat adsorbsion or heat loss is composed of conductive insulation material as well as radian barrier material. The insulating wrap conforms to the container shape and has multiple attachment elements for closing and retaining the insulating wrap to the container. The insulating wrap may also have attachment elements for adding a top and/or a bottom insulating cover also comprising conductive insulation material as well as radian barrier material. The insulating wrap may employ insulating tape on the top and bottom edges to protect the edges as well as to further improve heat transfer at the interface between the top or bottom covers and the insulating wrap. In one embodiment the top cover may have an integrated handle piece where the top and bottom cover attachments have sufficient strength to allow a container to be lifted. This embodiment facilitates lifting of a insulated container.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related to the following commonly owned co-pending U.S. Patent Application:

Provisional Application Ser. No. 60/671,372, “Insulating/Protective Covering for a Container,” filed Apr. 14, 2005, and claims the benefit of its earlier filing date under 35 U.S.C. §119(e).

TECHNICAL FIELD

The present invention relates in general to insulating and/or protective coverings.

BACKGROUND INFORMATION

Equipment used in many applications can be exposed to adverse conditions. The conditions can vary from sunlight exposure to corrosive gases. The condition that is being protected against determines what method is best for protection.

Sunlight as radiant energy can be destructive to materials as well as an unwanted heat source. A device that would protect against sunlight brings the advantage of reducing the affects of radiant energy in the form of heat and material breakdown. A device that further insulated would increase the utility of thermal transfer.

There is, therefore, a need for a protective covering that insulates.

SUMMARY OF THE INVENTION

An insulating wrap to inhibit heat transfer to or from a container comprises conduction insulating material as well as material to prevent radiant heat transfer. The insulating wrap conforms to the shape of the container and has attachment elements for closing the insulating wrap and retaining it against the container. The insulating wrap may have additional attachment features for coupling an insulating top cover and an insulating bottom cover. The top and bottom covers also have material for preventing conductive as well as radiant heat transfer. The attachment elements may include hook and loop, magnetic, mechanical snaps, straps with latches, etc. If the attachment elements provide sufficient strength for lifting a loaded container, the insulating top cover may be fitted with a handle element to allow the container to be lifter without providing an opening to a container handle further preventing heat transfer. Insulating tape may be used on the top and bottom edges to protect the edges and to further reduce heat transfer.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention.
