Abstract
A travel mug includes a container and a lid in combination. The container has a handle and an annular lip. The lid has an annulus capable of forming a seal with the top side of the annular lip. A cylindrical well in the lid has a vertical dividing wall so that the lid may be readily rotated by hand. Two retaining arms extend from the underside of the lid and engage the underside of the annular lip to pull it into tight abutment therewith. Diametrically opposed gaps in the lip act as passageways for the retaining arms. Diametrically opposed notches in the lid when aligned with the gaps allow a person to drink from the otherwise sealed container.
Claims4
A travel mug comprising in combination:
- a. a container having a base and continuous side wall to form an internal chamber;
- b. a handle attached to the exterior of said side wall;
- c. a relatively thin annular lip extending from the interior of said side wall, said lip having an underside, a concave annular cavity on said underside, and an upper side;
- d. two diametrically opposed gaps in said annular lip located approximately 90 degrees from a point on the annular lip nearest to said handle;
- e. a lid member having an annulus, said lid annulus having a horizontal top surface, an outer edge, and a lower surface portion extending inwardly from said edge;
- f. a well in said lid member surrounded by said annulus, said well having inner and outer vertical surfaces and inner and outer horizontal surfaces forming an opening in said top surface of said annulus;
- g. first and second notches in said annulus' outer edge;
- h. first and second retaining arms fastened to said well's outer horizontal surface;
- i. a vertical dividing wall spanning the diameter of said well, thereby creating two half-cylindrical wells;
- and
- j. means in said well for permitting fluid flow between said half-cylindrical wells, whereby said retaining arms are passed through said gaps in said lip and are adapted to bear against said concave annular cavity for thereby sealing said internal chamber and for allowing fluid within to escape said container only through said gaps.

- g. first and second notches in said annulus outer edge;
- h. first and second retaining arms fastened to said well outer horizontal surface,
