US 5,171,081 A · Chemiluminescent reactive vessel

Abstract

A vessel for the containment of food or drink produces a chemiluminescent reaction when activated to provide an enjoyable effect for the user of the vessel. The vessel has inner and outer walls and floors with a space therebetween, and includes a chemiluminescent fluid within at least the floor space. Another chemiluminescent fluid is contained separately within a toroidal tube in the upper or lower rim of the vessel. The vessel and tube are preferably formed of a flexible and translucent plastic. Thus, when the rim is flexed the toroidal tube is compressed, causing the fluid contained therein to rupture a thin membrane separating the volumes of the tube and wall or floor space and allowing the fluid contained within the tube to flow into the space between the two walls and floors to mix with the other chemiluminescent fluid and thereby produce an interesting and pleasing glow from the vessel. A further variation on the above invention provides for containment of one of the fluids in a capsule in the base of the container. While a specific combination of chemicals known in the art is disclosed, a variety of chemiluminescent compounds may be used to provide different colors, brightnesses, reaction times, etc. The vessel may also be provided in a multitude of different shapes, so long as they are topologically related.

Dependent claims

A vessel having an outer convex wall communicating with an outer floor and an inner concave wall communicating with an inner floor and thereby defining a continuous wall space and floor space therebetween,

said outer wall and said inner wall sealed together at a common upper rim,
said upper rim including a toroidal tube monolithically formed therewith,
said toroidal tube having a lower side including a relatively thin membrane communicating with said wall space,
said toroidal tube containing a first chemiluminescent fluid,
at least said floor space containing a second chemiluminescent fluid, whereby
said toroidal tube is compressed causing said relatively thin membrane to rupture and said first chemiluminescent fluid flows from said toroidal tube through said wall space to mix with said second chemiluminescent fluid within said floor space and said wall space to produce a chemiluminescent reaction when said upper rim of said vessel is distorted.
