US Patent 7887461 Lip strengthening device

A facial muscle strengthening and lip strengthening device comprises a primary hinge attached to two articulating arms and biased to a predetermined position. Lip-engaging members are attached to the articulating arms opposite the primary hinge and are also attached to the articulating arms in a hinged manner. The lip-engaging members comprise saddle-shaped units to be disposed in front, back, and atop the lips of a user. To employ the device, a user places the device between the lips in a vertical, horizontal or slanted orientation and compresses the device, bringing the lip-engaging members proximally together and causing the primary hinge to depend laterally away from the mouth of the user.
