A wine glass constructed from molded plastic includes an upper body defining an upwardly narrowed flume for concentrating the wine bouquet, in combination with a contoured lower base defining an annular moat surrounding a central punt for enhanced visual inspection of the wine. In addition, the upper body further includes a notched indent at an outboard side thereof forming a shelf for facilitated fingertip grasping and manipulation of the assembled glass. In one form, the upper body and lower base of the wine glass are provided as separate modules adapted for assembly to form the wine glass, and disassembly for respective compact stacking. In another form, the wine glass has a one-piece construction adapted for compact stacking by nested reception of the upwardly narrowed flume partially into the underside of the lower base of an overlying glass in the stack.

A container having enhanced wall integrity and a rotational element is provided that includes a sidewall having polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. The peaks include first and second faces sloping in opposite directions designed to direct corners of the first container's sidewall toward the interior valleys of the second container in order to orient the containers as they are stacked.

A system with light-weight drinking cups that use small ball magnets embedded in the cup rim and in the bottom cup center. In a preferred embodiment, there can be four magnets at four locations around the rim and a magnet in the center of the bottom of the cup. This arrangement allows cups to be stacked easily even by very young children in a large variety of ways and configurations. The ball magnets align in an attraction mode. Hence, any two cups can be stuck together simply by bringing two of the magnets into proximity. The toy can yield large stacks with connections in many different configurations.

The present invention is directed to a stackable container system. The stackable container system can comprise a beverage container, a beverage container lid, a plurality of smaller containers, and a plurality of smaller container lids. The smaller containers and smaller container lids are configured to allow any of the smaller container lids to be used on any of the smaller containers. The bottom of the beverage container and the bottom of each smaller container is also configured to allow the beverage container or smaller container to be interlocked with the top of any of the smaller container lids. In addition to storing beverage ingredients, the stackable container system can also be used to store other edible and inedible ingredients.

An assembleable container for storing a liquid includes an upper main body having a first connector and a lower main body having a second connector. The first connector has a convex portion or a concave portion formed on an outer periphery of the upper main body. The second connector has a concave portion or a convex portion that is formed on an inner periphery of the lower main body and configured to fit into the convex portion or the concave portion of the first connector. When the first connector and the second connector are coupled to each other, a bottom surface of the first connector and a bottom surface of the second connector are disposed facing each other. The first connector and the second connector are coupled to provide a leakage prevention portion for preventing the liquid from leaking.
