The present invention relates to festive implements, particularly a handheld neon glow in the dark confetti launching device for launching neon glow in the dark confetti pieces when used under black light in the air. More specifically, the present invention may be a neon “glow in the dark tube” filled with neon “glow in the dark” confetti launching device that may be capable of dispersing neon glow in the dark confetti into the air while using a black light to make the neon confetti and the neon tube glow in the dark.
Many conventional launching devices, known in the art, including ‘cannons,’ etc., are used by people during the festive season to blast confetti in the air. From the devices using blowers with compressed AIR, these cannons and launchers use a variety of triggers to eject confetti into the air. In addition to the triggers, these devices are usually expensive and bulky with sharp edges. Furthermore, the usage of compressed air and other fuels increases the risk level for accidents.
Some conventional devices, including and as described in U.S. Pat. Nos. 1,153,207 and 1,491,809 assigned to ‘Samuel Eisenberg’ and ‘Macchia Camillo’ respectively disclose funnel-shaped confetti launching devices. Each of these devices requires the user to blow in the funnel in order to release the confetti from their housing enclosed within. Although the devices are relatively simpler than other confetti launchers as described above, expelling confetti to greater height requires a user to deploy a large amount of force through breathing. Such blowing renders these devices uncomfortable to use due to these limitations.
Another similar technique is disclosed in J.P Patent No. 3190529 assigned to Hojin Sasa, which discloses a container filled with confetti that can be operated manually. The user holds the container holding multiple winding tapes are stored.
Traditionally, a product disclosed in U.S. Patent Application 20080274663 assigned to Linda Dial disclosing pieces of confetti or a collection of pieces of confetti. The pieces of confetti include a material that is shiny or reflects light that is luminescent or phosphorescent or that glows in the dark to provide additional visual effects. Though the pieces of confetti glow in the dark, the application is limited to just pieces of confetti, and no launcher is included.
A few products, such as Pink Neon Confetti Cannon of Wedding Sparklers Outlet and Neon Confetti of Studio Pep, disclose neon confetti. Although these products may include the feature of glow in the dark confetti, they do not provide flicking confetti in an easy manner, which also looks beautiful when the confetti is ejected from the cannon. Also, the confetti may be randomly stuffed inside the tube, and these tubes always require a cap for keeping the confetti inside the cannon.
The confetti devices in the market are not easily operated. They do not have a functionality of glowing in the dark, and thus, are nor suitable for use during low light conditions such as night parties. And the confetti launching devices that include neon color confetti do not include the confetti in a cassette form or in an organized manner. Instead, such devices are stuffed with confetti, and they require a cap to hold the confetti inside the tube.
To overcome the drawbacks of awkward prior art confetti launching devices and to increase the market for confetti devices, there is a need for a “hand flick” neon glow in the dark tube with neon glow in the dark confetti inside the launching device. The technology disclosed in This document overcomes these limitations as it is easy to use, and both the tube and the confetti can glow in the dark.
It may be apparent now that numerous methods and systems are developed in the prior art that are adequate for various purposes. Furthermore, even though these inventions may be suitable for the specific purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described. Thus, there is a need for an easy to use “hand-flick” neon glow in the dark confetti tube filled with neon glow in the dark confetti that glows under black light.
The present invention solves the problem posed by the prior art by presenting a simpler, non-mechanical design for a neon glow in the dark confetti launcher. A neon glow in the dark launching device of the present invention includes a hollow neon glow in the dark tube filled with bundles of individual neon glow in the dark confetti pieces. The neon glow in the dark confetti bundles may be partially wrapped around by an outer layer, or wrapper, that loosely holds the bundle of individual confetti pieces in place. Such a wapper holds the neon glow in the dark confetti together until it is dispersed into the air. The partial wrapping of the neon glow in the dark confetti bundles causes the bundles to burst open into a celebration of color and light when the bundles reach, or are near, the apex of their trajectory. Such an arrangement, in its entirety, forms a neon glow in the dark confetti bundle that may be loaded into a hollow neon glow in the dark tube. Both the neon glow in the dark hollow tube and the neon glow in the dark confetti bundles are manufactured using bright neon glow in the dark color palettes. For this document, a “neon tube” is a “glow in the dark tube,” where at least a portion of its outer surface defines a fluorescent quality. Similarly, a “neon confetti bundle” is a “neon glow in the dark confetti bundle” comprising a plurality of confetti pieces defining a fluorescent quality. Individual “glow in the dark confetti pieces” may be referred to as “neon confetti” or “neon confetti pieces.” The fluorescent quality may be achieved by fluorescent paint (blacklight paint) that glows in the presence of a blacklight in low light conditions. Luminous paint or luminescent paint may also be used.
The hollow neon glow in the dark tube of the launching device defines two opposing ends—the proximal end where users grip the at least partially hollow tube, and the opposing/opposite end, called the distal end, where one loads the neon glow in the dark confetti bundles into the at least partially hollow tube and where the confetti bundles exit the hollow neon glow in the dark tube when the user activates the launching device with the “flick of the wrist.”
One object of the present invention may be to present a neon glow in the dark confetti launcher that may be simple and safe to be used by any person irrespective of the skill and age. Unlike other launchers that use triggering catalysts like compressed Co2 or igniting material, the launching device of the present invention uses a simple non-mechanical solution to eject the neon glow in the dark confetti. Such a configuration makes the neon glow in the dark launching device safer by lowering the risk of accidents and lower fire hazard risks.
Another object of the present invention may be to provide an easy to handle design while adding portability to the neon glow in the dark confetti launching devices. The neon glow in the dark launching device of the present invention may be in the form of the at least partially hollow neon glow in the dark tube that may be lightweight and easy to carry around. It can be 6″, 9″, 14″ or 18″ in length.
Still another object of the present invention may be to arrange the loose neon glow in the dark confetti into neat stacks like a bundle of individual neon glow in the dark confetti pieces. Such bundles allow packing of more confetti per unit area (approximately 850 pieces of neon glow in the dark confetti in the 6″ tube, 2,860 pieces of neon glow in the dark confetti in the 9″ tube, 1,920 pieces of neon glow in the dark confetti in the 14″ tube and 4,000 pieces of glow in the dark confetti in the 18″ glow in the dark tube). Such a precise manufacturing process minimizes the possibility that the confetti will fall out of the tube while not being too tight in the tube, allowing the confetti bundles to disperse into the air easily with the “flick of the wrist.” The proprietary manufacturing specifications of each of the bundle of individual stacks of neon glow in the dark confetti also prevents clumping of confetti inside the hollow neon glow in the dark tube.
A further object of the present invention may be to avoid mixing or slippage of the neon glow in the dark confetti pieces by holding them together in a bundle of individual neon glow in the dark confetti bundles having layers within. The confetti bundle stacks may be held in place by a relatively longer strip of material of the neon glow in the dark confetti, partially covering the stack. The partially wrapping of each stack method of manufacturing allows the stacks of the neon glow in the dark confetti to go higher into the air.
Another object of the present invention may be to allow filling of the neon glow in the dark tube with various stacks of neon glow in the dark confetti, thereby inserting hundreds of individual neon glow in the dark confetti pieces that inside the tube. The neon glow in the dark confetti glow under a black light making the neon glow in the dark launching device and the neon glow in the dark confetti both visible and attractive to the user in low light conditions.
Yet another object of the present invention includes a confetti launcher of the present invention constructed with a pre-specified color pertaining to a specific party or a religious/national celebration if requested.
These and other objects and advantages will become apparent from the following description of several illustrative embodiments of the invention, as shown in the following illustrative drawings.
Other objectives and aspects of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the features in accordance with embodiments of the invention.
Embodiments of the present invention may employ any or all of the exemplary aspects above. Those skilled in the art will further appreciate the above-noted features and advantages of the invention together with other important aspects thereof upon reading the detailed description that follows in conjunction with the drawings, which illustrate, by way of example, not limitation, the features in accordance with embodiments of the invention. The summary is not intended to limit the scope of the invention, which may be defined solely by the claims attached hereto.
Embodiments of the invention are described with reference to the following drawings, wherein:
The present invention relates to festive implements, particularly a neon glow in the dark launching device for emitting neon glow in the dark confetti into the air. The launching device may be a hollow neon glow in the dark stick filled with fluorescent neon glow in the dark confetti inside it. The neon glow in the dark confetti and the hollow neon glow in the dark stick are both preferably manufactured in eye-catching neon glow in the dark colors. The invention provides a safe and easy to use neon glow in the dark confetti launching device for all age groups. For this document, a “hollow tube” means “at least partially hollow tube,” and a “hollow stick” means “at least partially hollow stick” unless expressly stated otherwise. The “hollow tube” may define shapes such as a walking cane and a magician's wand. Further, “neon-color” broadly applies to a wide range of fluorescent or ultra-bright colors. It should be appreciated that there is a fluorescent or ultra-bright version of almost every primary and secondary color. Further, at least part of the hollow tube/stick described herein may be at least partially translucent or transparent.
For one embodiment, a hollow neon glow in the dark tube may be filled with bundles of stacked confetti pieces, which are partially wrapped with a relatively longer strip of tissue or PVC film confetti material or any other suitable material known in the art. With a simple “flick of the wrist,” such neon glow in the dark confetti bundles are ejected out of the hollow neon glow in the dark tube when the user moves her arm and wrist quickly. The relatively longer strip of material acts as an outer layer and holds the confetti pieces together. The bundles of confetti are partially wrapped with a relatively longer confetti piece to facilitate easy dispersion of confetti pieces when the neon glow in the dark launching device is activated. The manufacturer specifications for a launching device may specify a predefined weight range (+/−5%) and size range (+/−5%) for the neon glow in the dark confetti bundles. Such specifications are selected to minimize the possibility that the bundles of neon glow in the dark confetti are too tight and/or too loose inside of the neon glow in the dark tube.
The hollow neon glow in the dark tube 102 defines a cavity in which multiple partially wrapped bundles of neon glow in the dark confetti are stacked on top of each other in a row. In one embodiment, the longitudinal axis of the hollow neon glow in the dark tube and the neon glow in the dark bundles of confetti may be aligned together. The neon glow in the dark bundles of confetti may be arranged inside the hollow neon glow in the dark tube such that the layers of individual neon glow in the dark confetti are parallel to the longitudinal axis of the hollow neon glow in the dark tube. In an alternate embodiment, the layering in each bundle of individual neon glow in the dark confetti can be positioned at different angles to the longitudinal axis of the hollow neon glow in the dark tube so that each bundle of glow in the dark confetti remains substantially intact prior to triggering of the neon glow in the dark launching device 100. The neon glow in the dark bundles may comprise an outer layer 104 wrapped around a bundle of individual glow in the dark confetti 106. The outer layer 104 may be a strip of material that is relatively longer than the confetti 106 so that it may at least partially wrap around and hold the confetti 106 together. The outer layer 104 and the neon glow in the dark confetti 106 can be formed either of the same material or different materials. For one embodiment, the confetti 106 and the outer layer 104 both are formed of light, delicate material such as Crepe paper, craft paper, tissue paper, PVC film or metallic film, and the like.
For one embodiment, the bundle of individual neon glow in the dark confetti forms a cuboid. The bundles of individual neon glow in the dark confetti 106 may comprise confetti 106 of the same color, or they may be assorted colors. Similarly, the hollow glow in the dark tube 102 and the bundle of individual neon glow in the dark confetti 106 may have the same neon glow in the dark colors or different neon glow in the dark colors. Notably, as noted above, neon glow in the dark colors are an extremely bright (ultra-bright) version of primary or secondary colors that exhibit luminescence when used under black light.
As noted previously, the bundle of individual glow in the dark confetti 106 may be at least partially surrounded by the outer layer 104. Such an outer layer may define a u-shape. The outer layer 104 loosely holds the individual neon glow in the dark confetti 106 and may cover three consecutive faces of the cuboid. The size of the bundles of neon glow in the dark confetti required for a particular hollow tube design may be determined and specified so that such bundles do not fall out of either end of the hollow tube under gravity. Such confetti bundle dimensions would then be used in a precise manufacturing process. The predetermined confetti bundles sizes define a confetti bundle size and shape that trap the confetti bundle inside the hollow tube 102 by friction between an inner surface of the hollow neon glow in the dark tube 102 and a surface of the bundle of neon glow in the dark confetti.
In an alternate embodiment, a plug, such as a disc or piece of foam, defining an outer diameter similar to the internal diameter of the hollow neon glow in the dark tube 102 may be used at either end of the hollow neon glow in the dark tube 102. The plug acts as a stopper for the neon glow in the dark confetti bundles inside the tube. The plug may be made up of lightweight materials such as cardboard, foam, paperboard, and the like. The diameter of the inner volume of the hollow neon glow in the dark tube may be about 1.5 cm or higher depending on the amount of neon glow in the dark confetti a user wishes to deploy into the air using the launching device 100.
For one embodiment, the diameter of the hollow neon glow in the dark tube ranges from about 1.5 cm to about 2.3 cm, and the length of tube 102 ranges from about 6 to about 18 inches, which surprisingly, is the size most suitable for handling and use by non-professionals. Measurements for the various parts of the invention are +/−10%, and “about” means+/−10% unless expressly stated otherwise.
It will be appreciated that the length of the hollow neon glow in the dark tube 102 may be any desired length including 6 inches, 9 inches, 14 inches, and 18 inches, and the diameter of the hollow neon glow in the dark tube may be one of a 0.921-inch, 0.740-inch, 0.910 inch, and 2 inches, respectively. The neon glow in the dark hollow tube 102 may comprise a “skin” (wrapper/cover) configured to cover at least part of the exterior portion of the hollow glow in the dark tube 102. Such skin may be a predefined skin design and may be user-selectable. For one embodiment, the skin design may be a custom design defined by a user during the ordering process via software provide for such purpose. Such allows for a custom skin design tailor-made for a particular event.
The neon glow in the dark launching device 100 may be triggered in any number of ways by generating an unbalance in the forces between the confetti bundle inside a launching device 100 and the launching device 100, which causes the confetti bundle to accelerate. Generating a centrifugal force is one example. For example, by holding (in either hand) a neon glow in the dark hollow tube (at either end), filled with neon glow in the dark confetti 102, with the arm straight up into the air (12:00 position), then moving the forearm or arm to the 3:00 position, and then returning the forearm or arm to the 12:00 position, quickly, while flicking the wrist at the same time, the bundles of neon glow in the dark confetti are exposed to an unbalanced force relative to the launching device 100 causing the bundle to accelerate in the direction of the distal end causing the confetti bundles to be projected out the distal end of the launching device 100 and into the air. Stated differently, the movement dislodges the bundles of neon glow in the dark confetti, which are ejected out from the distal end of the neon glow in the dark launching device. As the bundles of neon glow in the dark confetti exit the confinement of the hollow glow in the dark tube, the outer layer begins to separate from the bundle of individual neon glow in the dark confetti pieces until the separation allows the bundle to burst open, creating a starburst of color and light. Ideally, the starburst occurs at a predefined speed, which should occur at or near the apex of the trajectory for the confetti bundles.
One or more neon glow in the dark confetti plugs (discs or pieces of foam) may also be used for the construction of the neon glow in the dark launcher of the present invention. The disc may be configured to be placed inside the inner volume of the hollow tube 102, near one of the ends. Depending on the end design, the disc or foam pieces may be visible from the cross-sectional opening of either the proximal end, or the distal end, or both the ends of the hollow neon glow in the dark tube 102.
Alternatively, multiple discs or pieces of foam can be placed in the inner volume of the neon glow in the dark tube at regular intervals creating segments inside the hollow tube 102. These segments may contain separate neon glow in the dark confetti bundles. The discs or pieces of foam are held in place temporarily due to interaction between rough surfaces of the disc or foam edges in the inner surface of the hollow neon glow in the dark tube 102. Multiple segments allow a user to better control the ejection of the neon glow in the dark confetti pieces from the hollow glow in the dark tube 102. Instead of the contents being dispensed all at once, each disc or piece of foam is suitably sized so that they move slower through the tube 102 than and unimpeded neon glow in the dark bundle of confetti pieces 106. Such a configuration allows for the creation of multiple events of neon glow in the dark confetti 106 launchings by the same device without reloading.
After gripping either end (depending on the configuration) of the neon glow in the dark tube 102 by hand, the user should extend their arm upward above her head to the 12:00 position. The user may then bring her forearm back to the 3:00 position and return the arm to the 12:00 position, quickly, while flicking the wrist at the same time, causing the neon glow in the dark confetti to flutter, fly and/or float out of the neon glow in the dark tube (depending on the confetti configuration). That said, for the confetti bundles that are wrapped as described above, the confetti bundles should fly along their disbursement trajectory and not burst apart until they reach a predetermined speed, which should occur near the apex of their trajectory. For one embodiment, the confetti bundles burst apart approximately 15 feet from the launcher device 100.
As noted above, the sudden movement of the arm creates a centrifugal force (acceleration) that ejects the neon glow in the dark confetti bundles from the launching device 100 where they burst open in the air to release the neon glow in the dark confetti 106 pieces. The neon glow in the dark launching device 100 should be moved with sufficient speed in order to generate the force needed to eject the neon glow in the dark confetti bundles out of the hollow neon glow in the dark tube 102. It may be necessary that the user move/flick their wrist or forearm in an arcuate movement to create centrifugal forces that act on the contents of the hollow neon glow in the dark tube 102 and empties the cavity inside. One of ordinary skill in the art will appreciate that when the hollow neon glow in the dark tube 102 is moved along a curved path, the longer the hollow neon glow in the dark tube 102 the faster the distal end moves relative to the proximal end and the more centrifugal forces and associated acceleration generated.
The design of the neon glow in the dark launching device 100 may be simple and easy to use by users of any age group or skill. The neon glow in the dark launching device 100 does not use chemical fuels such as compressed gases like co2 to explode the neon glow in the dark confetti 106 in the air. The current design minimizes risks, which should result in fewer accidents when using such devices. Although a typical neon glow in the dark launching device 100 may use paper neon glow in the dark confetti 106, other materials may also be used, such as Mylar, PVC plastic FILM, metal foil, other metallic material and the like. Furthermore, the device of the present invention may be made of lightweight material, which may be easy to carry and provides for more portability compared to other confetti launchers known in the art.
Referring now more particularly to
The hollow tube 102 of the launching system 100 is configured to receive a plurality of confetti bundles 118 disposed along the central axis 116 in either a stacked or unstacked configuration. At least one confetti bundle 118, (comprising one bundle or a stacked pair of confetti bundles 118), is suitably sized so that at least part of at least one outer surface defined by said at least one confetti bundle 118 engages with a portion of the inner surface defined by the hollow tube 102 to create friction therebetween that holds said at least one confetti bundle inside said hollow tube 102 while under the force of gravity. For such a configuration, the force of gravity alone will not be enough to eject the confetti bundles 118 out of the hollow tube 102. Thus, no end cap is required to hold the confetti bundles 118 inside the hollow tube 102. However, by rotating the second end 114 about the first end 112, a centrifugal force is created that is large enough to eject the confetti bundle 118 out of the second end 114 of the elongated body 110 as depicted in
The neon glow in the dark confetti pieces and the outer layer 104 should be made of the lightest and most delicate material possible (such as tissue paper or a PVC neon glow in the dark film) so that a “flick of the wrist” of the user's hand may be enough to dislodge such material from the hollow neon glow tube 102. It is noted that gravity acts on all things equally, which means all things fall at the same rate assuming no forces other than gravity. However, when the “thing” is confetti, and the environment is open-air, lighter confetti floats more, and thus, falls slower than heavier confetti. If the confetti material is too heavy, the confetti 106 will simply plummet to the ground quickly without creating visually striking displays of movement to appeal to an audience. Yet light materials are difficult to project through the air. Thus, for one embodiment, the confetti wrapper used to form a confetti bundle, as described above, should be materially heavier than the individual confetti pieces. For example, a bundle wrapper may be twice the weight of all the individual confetti pieces making up a bundle. Such allows the confetti bundle to be projected further from the launching device 100 before bursting open while still providing for a longer-lasting confetti visual experience.
The neon glow in the dark launching device 100 of the present invention may also use predetermined colors for the hollow neon glow in the dark tube 102 and the neon glow in the dark confetti 106 filled inside. The color of the hollow neon glow in the dark tube 102 and the neon glow in the dark confetti may be of the same neon glow in the dark color or the color of the hollow neon glow in the dark tube 102, and the neon glow in the dark confetti 106 may be different. Alternatively, the hollow neon glow in the dark tube 102 may be made with a single predetermined neon glow in the dark color, and the neon glow in the dark confetti 106 filled inside may be made with multiple pre-selected colors. Such pre-selected neon glow in the dark colors are picked according to a specific festivity, with the neon glow in the dark launching device being used exclusively for that celebration. The examples include all black light functions, including dances, bingo parties, nightclubs and bars, and blacklight school parties.
The number of neon glow in the dark confetti pieces 106 may vary according to the length and cross-sectional area of the hollow neon glow in the dark tube 102 used in the construction of the launching device 100. It may be preferable to manufacture the hollow neon glow in the dark tube 102 and the bundle of individual neon glow in the dark confetti pieces 106 in neon glow in the dark colors, as these colors are bolder and more attention seeking. Unlike other party novelties, the launching neon glow in the dark device 100 of the present invention can be used in a dark space which has neon glow in the dark black light lighting since the neon glow in the dark confetti pieces 106 need the neon glow in the blacklight, so the neon glow in the dark confetti bundles are visible to the audience. As is well known, neon glow in the dark colors will “glow in the dark” under black-lighting.
The shape of the neon glow in the dark confetti 106 also plays on the role of proper segregation in air and rate of descent and movement through the air. In one embodiment of the present invention, the individual neon glow in the dark confetti pieces 106 are manufactured as rectangular strips. Other shapes that can be employed are diamonds, squares, trapezoids and triangles, and the like. However, narrow trapezoids descend at a faster rate with more vertical movements than the other shapes that show staggered horizontal movements during descent. The narrow or tapering edge of the shape leads the other edge during downward movement accelerating the descent than other shapes. The triangular-shaped neon glow in the dark confetti spiral downward and act as a whirlybird.
A typical rectangular shape, on the other hand, provides a fluttery movement until landing on the ground. The shape also supports signature staggered “fluttery” movement of the piece 106 when propelled in the air. Such movements provide more appeal to owe created by the launching device 100. In one embodiment, confetti manufacturing methods known in the art can be used for the launching device 100, such as die-cutting various shapes as hearts, rose petals, stars, and apple leaves, and so on. Ideally, the hollow tube 102 would be at least two inches in diameter or width to lunch such shapes.
Further in
For maximum fluttering effect when falling, it has been discovered that, surprisingly, the Length/width (L/W) ratio should be in the order of 1.75 to 10.0, or 2.5 to 7.0 depending upon the type of falling motion desired as will be more fully described hereinafter. Such four-sided pieces are referred to herein as elongated rectangular 1 inch shapes.
The shapes illustrated in
In addition to fluttering vertically instead of horizontally, neon glow in the dark confetti pieces 106, in the shape described with respect to
