Title: Lester G Burch: Innovator in Container Technology
Introduction
Lester G Burch is a notable inventor based in Arvada, Colorado, recognized for his contributions to container technology. He holds a total of 4 patents, showcasing his innovative approach to creating solutions for materials with volatile components.
Latest Patents
Among his latest inventions is the "Laminated Materials Container." This container is designed to maintain substantial transparency while housing materials that have volatile components. It features a tubular housing with first and second closing structures at opposite ends. The housing is constructed as a laminate, incorporating a thin inner lining of high barrier amorphous nylon and an outer sleeve of low barrier plastic, such as polyethylene teraphthalate. This design is particularly suited for viscous caulking compounds, with a first closing structure that includes an end wall, nozzle, and snout assembly, while the second structure is defined by a movable piston that slides within the housing interior.
Another significant patent is the "Materials Container with Index Markings." Similar to his previous invention, this container is constructed for viscous materials with volatile components and maintains substantial transparency. The housing may be entirely made of amorphous nylon or formed as a laminate. It is specifically adapted for caulking compounds, featuring indexed markings on the transparent side wall and snout. This allows users to sever the snout at a desired location, determining the outlet size and informing them of the length of the caulking bead that can be obtained from the remaining contents.
