Lid assemblies for storage containers including vibration damping substrates

A lid assembly for a storage container, comprising:

• an outer panel comprising an inner facing surface;
• a reinforcement panel extending parallel to the outer panel and comprising:
• an out-facing surface in opposition to the inner facing surface of the outer panel;
• and
• one or more reinforcement grooves extending out of a plane of the reinforcement panel and defining outboard pockets of space between the outer panel and the reinforcement panel;
• a first vibration damping substrate coupled to the inner facing surface of the outer panel within one of the outboard pockets of space;
• a second vibration damping substrate coupled to the out-facing surface of the reinforcement panel within one of the outboard pockets of space, wherein the first vibration damping substrate and the second vibration damping substrate are spaced from one another in a direction perpendicular to a plane of the outfacing surface of the reinforcement panel with open space between the first vibration damping substrate and the second vibration damping substrate;
• and
• a sealant strip located at an apex of the one or more reinforcement grooves between the reinforcement panel and the outer panel to provide a seal between the one or more reinforcement grooves and the outer panel.

A method of producing a storage container comprising:

• assembling a lid assembly, comprising:
• affixing a first vibration damping substrate to an inner facing surface of an outer panel of the lid assembly;
• affixing a second vibration damping substrate to an out-facing surface of a reinforcement panel of the lid assembly opposite from the first vibration damping substrate such that a cross-section of the lid assembly taken perpendicular to a plane of the out-facing surface of the reinforcement panel extends through both the first vibration damping substrate and the second vibration damping substrate;
• and
• subsequently unopenably coupling the outer panel of the lid assembly to the reinforcement panel of the lid assembly so that the inner facing surface of the outer panel opposes the out-facing surface of the reinforcement panel, such the first vibration damping substrate is not affixed to the out-facing surface of the reinforcement panel or any structure between the outfacing surface of the reinforcement panel and the first vibration damping substrate;
• and
• coupling the lid assembly to a base portion, wherein the base portion defines an interior of the storage container.
