Confetti launcher

Abstract

A novelty device in the form of a confetti launcher intended for placement on a food product, such as a cake, has a base supporting a generally upright confetti launch tube. A plunger is mounted for travel within the launch tube from a first lower pre-launch position to a second post-launch position. The plunger is retained in the pre-launch position by a release mechanism, which is activated by a lit fuse severing a cord of the release mechanism.

Claims

1. A confetti launcher, comprising a base supporting a generally upright confetti launch tube; a plunger mounted for travel within the launch tube from a first lower pre-launch position to a second post-launch position; a spring for driving the plunger from the prelaunch position to the post-launch position, and a fuse-activated release for the plunger, the release comprising a cord positioned for severing by burning of the fuse, the fuse serving as a delay timer for the release, the cord having an initial state in the form of a taut closed loop that passes through a bore in the plunger with the plunger in the pre-launch position.

2. The confetti launcher of claim 1 wherein the fuse is mounted in a bore in a launch cap located on the base, and the cord loop includes a portion on the exterior of the launch cap adjacent the fuse.

3. The confetti launcher of claim 1 wherein the plunger includes an upper section of a first diameter and a collar positioned below the upper section of a second; larger diameter, the launch tube having a first section with an inner diameter to accept the collar of the of plunger and a second section, positioned above the first section, with an inner diameter to accept the first section of the plunger but not the collar.

4. The confetti launcher of claim 3 wherein the first and second sections of the launch tube intersect at a point that provides a stop for upward travel of the plunger.

5. The confetti launcher of claim 3 wherein the spring is positioned between a pedestal of the base and the collar.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) A fuller understanding of the invention will be obtained upon consideration of the following detailed description of an illustrative embodiment of the invention, when reviewed in connection with the annexed figures, wherein:

(2) FIG. 1 is a perspective view of a launcher of the present invention in place on a cake;

(3) FIG. 2 is an enlarged perspective view of the launcher of FIG. 1 detailing the fuse and the exposed portion of the release mechanism;

(4) FIG. 3 is a cross-sectional view of the launcher of FIG. 1 with the plunger in the initial cocked position; and

(5) FIG. 4 is a cross-sectional view of the launcher of FIG. 1 after launch of confetti.

DETAILED DESCRIPTION OF THE INVENTION

(6) With initial reference to FIG. 1, confetti launcher 10 is intended to sit upon an appropriate supporting object, such as cake 12. When operated, ignition of fuse 14 causes the launcher to be activated, allowing confetti 16 to be ejected from the upper open end of launch tube 18. In is to be appreciated that, depending on the specific nature of fuse 14, the fuse may disintegrate upon its burning. The confetti, which may be of paper or plastic pieces as known in the art, or small edible pieces, such as candy bits, shoot upward and fall back down around the launcher.

(7) Referring more specifically to FIGS. 2 through 4, launching tube 18 extends upwardly from base 20. Base 20 includes downwardly-extending conical mounting wedge 22 which is inserted into the object, such as cake 12. The wedge supports the launcher 10 in the desired position.

(8) Launching tube 18 carries plunger 24, adapted to travel upward from its initial pre-activation position as depicted in FIG. 3 to the after-launch position as depicted in FIG. 4 under the influence of spring 26. Spring 26 sits on pedestal 30 of the base, encircles the lower portion 28 of plunger 24, and exerts its spring force between the pedestal and the lower surface of collar 32 of the plunger, which is of a greater diameter than the portion of the plunger above the collar. Collar 32 rides in the lower portion 34 of the launch tube, the upper end of which provides a stop for the collar and thus the plunger when activated. As seen in FIGS. 3 and 4, portion 34 has an inner diameter sufficient to accept the collar, terminating at its upper end 42 by a section of the tube of a lesser diameter to accept only the portion of the plunger above the collar, producing a stop for the plunger, seen in FIG. 4. The length of the plunger is such that its upper end extends into the lesser diameter section even when the plunger is in the pre-activation position of FIG. 3, such that the plunger is guided along its path of travel by the lesser diameter portion.

(9) The plunger is retained in the initial pre-activation by a release mechanism, which may comprise string or cord loop 36 in the open interior of the base which passes through bore 38 in the lower portion 28 of plunger 24. The string passes outwardly through a first bore in hemispheric launch cap 40 located on the base to place the exposed portion of the string in close proximity to, and preferably in contact with, the fuse, and then loops back into the base through another bore. The string loop is taut and strong enough to hold the plunger in the cocked position against the force of the compressed spring 26. The loop may be formed by passing an end of a length of string through the bore 38, threading it into the launch cap and across the string guides and then back into base. Appropriate tension is applied to the string to hold the plunger in the cocked position and the ends of the string tied together. Any additional length of free string beyond the tying knot may be trimmed off.

(10) Fuse 14 is mounted in a bore in the launch cap, which positions the fuse in contact with the exposed portion of the string, as best seen in FIG. 2. When the fuse is lit, it burns down and burns through the string. With the string severed and its loop broken, the plunger is no longer retained in the initial position, and thus shoots upward by spring 26, ejecting the confetti from the launch tube. The time it takes for the fuse to burn down and sever the string provides a delay from lighting and can provide a degree of suspense as to what is to happen, culminating in the release of the confetti.

(11) The launch tube, plunger and base may all be fabricated from an appropriate plastic or like material, as known in the art. The fuse may be of a type generally known in the art for use in novelty devices, and may typically include single base powder, moisture proof glue and an oxidant. The string or cord may likewise be as known in the art, and may preferably be a cotton thread.
