Container for diplaying transitory moving images

DETAILED DESCRIPTION The invention provides a cylindrical display container for displaying transitory moving images that utilize complementary moire patterns or graphic images printed upon or applied in a fixed position on the container and upon a sleeve which overlies the image on the container itself.
The container is suited for holding liquid such as a beverage or a food and, in various forms of the invention, can comprise various forms of containers, especially disposable packaging such as bottles, cans, canisters or tins, mugs, or sports bottles for holding a beverage or food.
The container comprises a rigid container body having a cylindrical or frusto-conical upright side wall surrounding a vertical central axis located at the center of the container.
The container body also includes a bottom wall and has a top portion that terminates in an upper mouth through which liquid can be introduced and removed from the container.
On the outside surface of the side wall of the container is a visible moire image that includes a multiplicity of visible moire markings such as dots, lines, bars or other patterns.
A tubular sleeve is mounted upon the wall of the container for sliding rotary movement so that the sleeve can be rotated manually by sliding the sleeve to either the left or right about the center axis of the container wall.
The sleeve is also provided with visible moire markings such as dots, lines or bars that interact with the moire pattern on the container when the sleeve is rotated to produce the transitory images for attracting the interest and attention of the user.
The sleeve can be a rigid and self-supporting tube or, if desired, the sleeve can be a flexible plastic film that is either self-supporting or is limp, flaccid and will not hold its own shape until placed on the container, in which case the sleeve is supported by conforming closely to the exterior wall of the container body.
If desired, the plastic film can be somewhat elastic or capable of stretching slightly when mounted upon the container body so that it presses lightly against the wall of the container body, allowing friction to retain the sleeve in place
