An oral device may include a body. The body may have a main portion having an arch-shaped central portion, a first side portion extending from a first end of the central portion, and a second side portion extending from a second end of the central portion. The body may further include a first wedge portion provided on a bottom surface of the first side portion, and a second wedge portion provided on a bottom surface of the second side portion. Each of the first wedge portion and the second wedge portion may have a varying thickness.

Systems and processes for thermoforming an article and for preparing an article for thermoforming are disclosed. The system for thermoforming can include one or more heating stations and a cooling station. The system for thermoforming can further include an article movement mechanism that can couple to an article and rotate the article inside a heating chamber, inside a cooling chamber, or both. The system for preparing an article for thermoforming can include a vessel that comprises a port, and a negative pressure generation system coupled to the port. The system for preparing an article for thermoforming can further include a compression material that forms an interior portion for receiving an article. The negative pressure generation system can cause the compression material to expand to allow for insertion of the article into the interior portion of the compression material.

A fiber-reinforced thermoplastic laminate is disclosed that comprises continuous reinforcing fiber. The laminate is custom designed and fabricated to be molded into a specific article of manufacture. Some or all of the continuous reinforcing fiber are severed at precise locations based on the geometric and physical requirements of the article of manufacture to facilitate molding while preserving most of the strength provided by continuous reinforcing fiber.

The present invention provides a manufacturing device of a battery case including a first mold including a first space part having a shape corresponding to a storage part formed therein; a second mold including a second space part having a shape corresponding to the storage part and a through-hole communicating with the second space part formed therein, and coupled to the first mold with a laminate sheet interposed therebetween; and an air pressure regulator mounted in the through-hole in a state in which the first space part and the second space part are isolated from the outside, and increasing or decreasing an air pressure of the second space part through the through-hole to stretch and modify the laminate sheet into a shape corresponding to the first space part or the second space part.

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered to the inner surface of the body ply and has a portion extending across the aperture, forming a window into the container. The method involves providing a window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device that is adapted to release pressurized air into the container through at least one of the platens. The container is engaged between the platens in an airtight manner and, optionally, the container window is positioned adjacent the inside wall of the machine pocket. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.
