Lip suction device and related methods
A lip suction device. A rigid hollow form has an opening at a first end of the rigid hollow form and a cavity therein extending from the first end to a second end of the rigid hollow form. The rigid hollow form has an outer surface and a thickness at the opening between the outer surface and a surface of the cavity. The opening has an edge with a rounded shape, across the thickness at the opening, which is configured to form a substantially air-tight seal between a user's face and the edge when the rigid hollow form is pressed against the user's face near the user's lips. The rigid hollow form is configured so that when the user draws air into the user's mouth after forming a substantially air-tight seal, the user's lips are drawn into the rigid hollow form towards the second end of the rigid hollow form.
1. A lip suction device, consisting essentially of:
a rigid hollow form comprising an opening at a first end of the rigid hollow form and a cavity therein extending from the first end to a closed second end of the rigid hollow form, the rigid hollow form comprising an outer surface and comprising a thickness between the outer surface and a surface of the cavity;
wherein the opening comprises a rounded shape at the surface of the cavity extending across the thickness between the outer surface and the surface of the cavity.
2. The device of claim 1 , wherein the rigid hollow form comprises only a single opening.
3. The device of claim 1 , wherein the rounded shape is circular.
4. The device of claim 1 , wherein the rigid hollow form comprises a cross section comprising a shape of one of a circle and a rectangle with two opposing half-circle ends.
5. The device of claim 1 , wherein the opening comprises a shape of a circle.
6. The device of claim 1 , wherein the opening comprises a shape of a rectangle with two opposing half circle ends.
7. The device of claim 1 , wherein the rigid hollow form comprises a first outer diameter and a second outer diameter, the first outer diameter being closer to the first end than the second outer diameter, and the first outer diameter being larger than the second outer diameter.
8. The device of claim 1 , wherein the outer surface comprises a ribbed section.
9. The device of claim 1 , wherein the rigid hollow form comprises a ledge at the surface of the cavity.
