Abstract

A lid structure is formed of conjoined upper and lower sheets of material. One of the sheets has a receptacle formed therein which receives an elastomeric pad. The portion of the conjoined first and second sheets form a sealing flange which completely surrounds the periphery of the receptacle and which provides a surface whereby the lid may be secured to a container.

Claims

1. A lid structure for a compartment having a peripheral mounting surface thereon, comprising:

a first sheet having a receptacle formed therein;

a second sheet joined to the first sheet thereby to form an enclosed volume surrounded completely by a sealing flange; and

a self-healing pad of elastomer material received with the enclosed volume;

the sealing flange being adapted to be connected to a mounting surface of a compartment.

2. The lid structure of claim 1 wherein the pad is provided with a slit which defines an entry path for a member.

3. The lid structure of claim 2 wherein first sheet is secured beneath the second sheet so that the receptacle, when mounted to the compartment, projects into the volume of the compartment.

4. The lid structure of claim 1 wherein the pad is received within the receptacle with a slight clearance defined between the pad and the receptacle.
