Abstract: A valve assembly is disclosed that has a valve housing including a first axial end, a cap, a second axial end, and an airflow pathway extending from the first axial end towards the second axial end. The cap is positioned towards the second axial end. The valve housing includes an environmental opening configured for fluid communication with an outside environment, an enclosure opening towards the first axial end configured for fluid communication with an interior of an enclosure, and a film having an expansion diameter disposed in the valve housing laterally across the airflow pathway. The cap has an inner lateral surface and a piercing protrusion (having a piercing tip) extending from the inner lateral surface towards the first axial end. An axial distance is defined between the film and the inner lateral surface. A ratio of the axial distance to the film expansion diameter is at least 0.14.

Abstract: A visor and/or sandal straps that are flexible and may be shaped and bent without cracking is provided. A flexible wood veneer layer is positioned over the visor and/or strap. A layer of engineered paperbacked wood veneer is used to cover the visor and/or strap. This single layer of thin wood veneer with the attached adhesive paper is able to flex and bend using a process that involves a breaking down of the natural fibers of the wood through a mechanical tenderizing process. This process produces a flexible, bendable paperbacked veneer. The wood veneer may be obtained from tropical or domestic tree species. The wood veneer layer is then attached to the visor and/or strap with a flexible water-based adhesive that will not crack on bending. The veneer layer may be treated with a waterproofing agent or scented essential oils and may have an ornamental design.

Abstract: A bill for attachment to a support element (hat) is provided that comprises a flexible wood layer that can be bent and shaped without cracking. Also provided is a hat in combination with the bill of the present invention. The bill, as well as the hat and bill combination, provide the advantage of being attractive, weather resistant, flexible, and have the ability to be bent and shaped.
