ABSTRACT:
This invention relates to a mouth opener with the configuration of integrated twin cups that can be divided into two parts, i.e. a linear configuration body and twin cup body. The two parts have the functions of structural framework and flexible mouth opening support. The head handle is the middle point, joining two tail troughs to form an angle that can produce physical resiliency, so the tail troughs will have flexible supporting function for the mouth. The two tail troughs are provided with bevels which are inserted between the user's upper and lower teeth to insure that the mouth opener is properly and securely positioned in the oral cavity. The belly support wall is a sturdy structure for reinforcement of the fixing and support functions. The remaining fine parts are also designed for the enforcement of aforementioned functions.
