The beverage container comprises a body 612 and a top lid 654 that can be releasably attached to the top opening of the body. The top lid 654 and the top of the container body 612 can have complementary threading, such that the top lid 654 can be screwed onto the top of the container body 612. The top lid 654 contains a light assembly comprising a plurality of light emitting devices 622 positioned proximate the outer edge of the top lid 654, as shown in FIG. 17. The container body 612 comprises an inner wall 613 and an outer wall 614, as shown in FIG. 16.

[0099] The light emitting devices 622 can be light emitting diodes. The light assembly includes a power source and an on/off mechanism operatively connected to the light emitting devices 622. The on/off mechanism can be a tilt switch that turns on the light emitting devices 622 by a mechanism making power contact when the container 600 is tilted or shaken.

[0100] The top lid 654 can be made of a material that is not transparent or translucent. The top lid 654 includes a plurality of port holes formed in the underside of the lid 654, and each light emitting device 622 is positioned directly above one of the port holes so that each light emitting device 622 can project light downwardly into the container body 612.

[0101] The inner and outer walls 613, 614 can be made of a transparent or translucent material, such as polycarbonate plastic. The light emitting devices 622 are positioned in a circular formation along the outer edge of the top lid 654 such that the light emitting devices 622 project light into the space between the inner and outer walls 613, 614. Alternatively, the inner wall 613 is made of a material that is not transparent or translucent, such as stainless steel, and the outer wall 614 is transparent or translucent. In another alternative embodiment, only a portion of the outer wall 614 is transparent/translucent and the remaining portion of the outer wall 614 is not transparent or translucent. The transparent/translucent portion of the outer wall 614 serves as window that allows the light from the light emitting devices 622 to pass through. A logo can be printed on the transparent/translucent portion of the outer wall 614, and the logo is illuminated by the light emitting devices 622.

[0102] Another embodiment of the invention comprises an apparatus 700 comprising a beverage container 712, and a light assembly contained in a housing 754 that can be releasably attached to the base 713 of the container 712, as shown in FIGS. 18-20. The light assembly comprises light emitting devices 722, and a power source and on/off mechanism operatively connected to the light emitting devices 722. The beverage container 712 can be a tumbler comprising a base 713 and a sidewall 714 extending upwardly from the base 713. Preferably, the base 713 and the sidewall 714 are made of a transparent or translucent material, and the housing 754 containing the light assembly is made of a transparent or translucent material. Alternatively, only a portion of the sidewall 714 is made of a transparent or translucent material. A logo can be formed on the transparent/translucent portion of the sidewall 714, which acts as a window that allows the light emitting devices 722 to illuminate the logo. The light assembly housing 754 can have male threading 755 on its surface and the outer surface of the tumbler base 713 can have complementary female threading 715 that can mate with the light assembly housing threading 755. The light assembly housing 754 can be screwed onto the container base 713, and the light devices 722 beam light up through the container 712. The on/off mechanism can be a button or switch, or the light emitting devices 722 can be activated when the housing is rotated on the tumbler base 713. In an alternative embodiment, the light assembly can be housed in a transparent/translucent top lid, such as the lid 154 shown in FIG. 4, and releasably attached at the top opening of the tumbler. In this embodiment, the light assembly housing is a transparent/translucent lid that is screwed on at the top of the tumbler. The light emitting device contained in the lid beams light downwardly into the tumbler.
