CONFETTI
Pieces of confetti that have the ability to spiral or autorotate downward in a novel and pleasing fashion when falling are described. The downward spiral or autorotation of an individual piece of falling confetti of certain desirable embodiments can be described as being similar to the downward fall of a maple seed or the decent of an autorotating helicopter making an emergency, unpowered decent.
1. Field of the Invention
The present invention relates to confetti, to pieces of confetti, a collection of pieces of confetti and to an individual piece of confetti.
2. Description of the Related Art
Conventional pieces of confetti are pieces of paper that can be thrown in the air at special events, for example weddings and other celebrations. When thrown into the air, conventional pieces of confetti fall to the ground in a tumbling motion and in a generally straight path. Such tumbling action is well known and does not provide a very dramatic or unusual display. Attempts to design confetti with novel shapes and confetti that provide more pleasing visual effects have been described in U.S. Pat. Nos. 5,352,148, 5,419,731, 5,507,680, 5,643,042, and 6,027,773 and U.S. Patent Application Publication no. 2003/0143915. Generally, the pieces of confetti described in the above-listed publications have uniform area densities, are symmetrical about at least one axis and, more particularly, are symmetrical about two or more axes. The confetti described and illustrated in these publications do not provide irregular and/or unusual flight patterns. Thus, there is a need for confetti that provides a novel and improved display. One object of the present invention to provide confetti that falls in a pattern similar to the fall of a maple seed. Another object of the present invention is to provide confetti that spins, whirls, twirls or otherwise rotates toward the ground as opposed to tumbling toward the ground.
Furthermore, conventional confetti has little mass and is difficult to project into the air using confetti cannons and other devices that can be used for launching confetti. Thus, there is also a need for confetti with greater mass and/or greater density that can be launched farther.
BRIEF SUMMARY OF THE INVENTIONThe present invention provides pieces of confetti that include a head portion that has a head portion area wherein the head portion area has a head portion area density and a tail portion that has a tail portion area and the tail portion area has a tail portion area density, wherein the head portion area density is greater than the tail portion area density. In certain embodiments, the head portion area density is at least about 5 percent greater than the tail portion area density. In certain other embodiments, the head portion area density is at least about 10 percent greater than the tail portion area density. In other embodiments, the head portion area density is at least about 20 percent greater than the tail portion area density. In other embodiments, the head portion area density is at least about 50 percent greater than the tail portion area density. In still other embodiments, the head portion area density is at least about twice the tail portion area density.
In certain embodiments, pieces of confetti have a length and a width and the length is at least about two times the width. In other embodiments, the pieces of confetti each have a length and a width and the length is at least about three times the width. In still other embodiments, each of the pieces of confetti has a first end head portion and a second end tail portion and wherein the weight per unit area of the first end head portion is greater than the weight per unit area of the second end tail portion. In certain embodiments, the first end head portion comprises a weight. For example, the weight may be a seed, a drop of plastic, a drop of metal, a coating, or a ball bearing.
In certain embodiments, each of the pieces of elongated confetti has a height H and a tail end portion width WT wherein WT is not greater than one half of the height H. In certain other embodiments, the pieces of confetti have a height H, the first end head portion has a width WH that is not greater than one half of L and the second end tail portion has a width WT that is greater than second end tail portion width WH. In still other embodiments, the first end head portion has a width WH and the second end tail portion has a width WT that is greater than first end head portion width WH. In certain embodiments, the pieces of confetti comprise two sheets of material. For example, the pieces of confetti can be formed from two sheets of material adhered around a weight that is included in and located proximate the first end head portion
The present invention also provides a plurality of pieces of confetti where each of the at least two pieces of confetti each comprise an area and a center of area and a mass and a center of mass wherein the center of mass and the center of area are not at the same point on each of the at least two pieces of confetti. In certain embodiments, the pieces of confetti each comprise a first end head portion and the center of mass of a piece of confetti is closer to first end head portion of the piece of confetti than the center of area is to the first end head portion of the confetti. In other embodiments, the pieces of confetti each comprise a first end head portion and the center of mass of the piece of confetti is closer to first end head portion of the piece of confetti than the center of mass is to the center of the area of the piece of confetti. In still other embodiments, the pieces of confetti each comprise a first end head portion and second end tail portion and the center of mass is closer to first end head portion of the piece of confetti than the second end tail portion of the piece of confetti.
In particularly desirable embodiments, pieces of confetti of the present invention spiral, spin, whirl, twirl or otherwise rotate toward the ground downward when released from a height of greater than 12 feet as opposed to tumbling toward the ground like conventional confetti.
A full and enabling disclosure of the present invention, including the best mode thereof is set forth in the detailed description which makes reference to the appended figures in which:
The drawings and detailed description provide a full and detailed written description of the invention, the preferred embodiment, and of the manner and process of making and using it, so as to enable one skilled in the pertinent art to make and use it. The detailed description uses numerical and letter designations to refer to features in the drawings. Like or similar designations in the drawings and description have been used to refer to like or similar parts of the invention. The examples set forth in the drawings and detailed description are provided by way of explanation of the invention and are not meant as limitations of the invention. The present invention thus includes any modifications and variations of the following examples as come within the scope of the appended claims and their equivalents.
The present invention will now be described with respect to a first exemplary embodiment a piece of confetti 1 that is illustrated in a plan view in
In certain embodiments, a piece of confetti is a single piece of molded paper that has uniform density but that has a weighted first end because the first end is thicker than the other, second end. In the exemplary embodiment illustrated in
In the embodiment illustrated in
Alternatively, pieces of confetti 1 can be cut or otherwise formed from one or more sheets of paper or other materials that are available in sheet from, for example sheets of MYLAR and other plastic films. Thus, in certain desirable embodiments a piece of confetti is made from of a synthetic material such a sheet or paper or a sheet of plastic film. It may also be possible to provide a weighted head portion by including one or more extra layers of paper or by folding an extra section of paper in the head portion or even by including paper of a heavier basis weight in the head portion.
In certain embodiments, a piece of confetti has no dimension, for example a length that is greater than 6 inches. In certain embodiments, a piece of confetti has no dimension that is greater than 5 inches. In certain embodiments, a piece of confetti has no dimension that is greater than 4 inches. In certain embodiments, a piece of confetti has no dimension that is greater than 3 inches. And, in certain embodiments a piece of confetti has no dimension that is greater than 2 inches. In certain embodiments, a piece of confetti of the present invention is at least about 1 inch long and in other embodiments a piece of confetti of the present invention is at least about 1 and a half inches long.
Turning now to
In this exemplary embodiment the tail portion 16 is not weighted and has an area density that is less than the area density of the head portion, or the other half of the piece of confetti, to provide a piece of confetti that falls head first and spirals or otherwise rotates downward when released from a height. In certain desirable embodiments, the weighted head portion of a piece of confetti spirals downward with the tail portion spiraling further outward and behind the head portion. For example, in certain desirable embodiments a piece of confetti corkscrews, spirals, spins, whirls, twirls or otherwise rotates downward when released from a height of 12 feet or more as opposed to merely tumbling like conventional confetti. The flight of such an individual piece of confetti can be described as “autorotating” and is similar to the downward fall of a carpel from the flower of a tulip poplar (Liriodendron Tulipfera) tree, a maple seed, or another samara winged seed spiraling to the ground. The fall of an individual piece of confetti of certain embodiments of the present invention may also be described as being similar to the flight path of a helicopter during an unpowered, emergency descent.
Thus, in certain particularly desirable embodiments the weight per unit area or density of one half or one end of a piece of confetti is greater than the weight per unit area of the second half or second end of an individual piece of confetti. Thus, one embodiment of the present invention includes a collection of pieces of confetti that include a first end and a second end wherein the first end has an area density that is greater than the area density of the second end. In the embodiment illustrated in
In certain desirable embodiments, pieces of confetti are provided that asymmetric or are irregularly shaped. One such desirable embodiment is illustrated in a front plan view in

Yet another exemplary piece of confetti of the present invention is illustrated in
Pieces of confetti of the present invention may have shapes other than those specifically illustrated in the accompanying figures and may have the shape of any polygon, for example, a triangle, a tetragon, a square, a rectangle, a parallelogram, diamond, a pentagon, a hexagon, a heptagon and so forth. One or more of the corners of the polygon-shaped pieces of confetti can be rounded. For example, the pieces of confetti can have the shape of elongated oval, an ellipse, an ellipsoid or even a comet. Again, the shape of the confetti may be symmetrical or asymmetrical and may be regular or irregular.
Pieces of confetti of the present invention can be cut or stamped from materials other than paper. Specifically, pieces of confetti can be molded, stamped or otherwise cut from sheets of material including, but not limited to, plastic, metal, foil, metallic films MYLAR and other metal coated films. In addition, a piece of confetti of the present invention can be made from one or more sheets of paper or plastic. For example, in another embodiment illustrated in
It is believed that pieces of confetti of certain preferred embodiments of the present invention will spiral and/or twirl downward in a unique and visually pleasing manner as opposed to tumbling like the confetti described and illustrated in U.S. Pat. No. 5,507,760. Additionally, because confetti of the certain desirable embodiments of the present invention have increased mass and even increased density it is believed that such confetti can be thrown, shot, launched or otherwise propelled further by confetti cannons and similar devices for dispersing confetti. Examples of confetti cannons and other confetti dispersing devices are described in U.S. Pat. Nos. 5,015,211, 5,772,491 and 6,641,458.
