Self-igniting sparkler

Abstract

This invention is for an improved sparkler which has the feature of being self-igniting. The sparkler comprises a rod 12 having one end which functions as a handle 14. Adjacent to the handle 14 on the rod 12 and extending generally along the remaining length of the rod 12 is a pyrotechnic composition coating 16. Bonded to the pyrotechnic composition coating 16 at a point furthest from the handle 14 is a self-igniting match head tip 18. When the match head tip 18 is struck against a suitable surface, ignition occurs and the sparkler's display begins. This self-ignition feature distinguishes the invention from the sparklers currently available which require heat or flame from an external source to be applied to the sparkler to cause ignition.

Description

[0001] a. Field of the Invention[0002] This invention relates to a new type of sparkler of the type used for pyrotechnical displays for amusement and holiday celebrations, such as the Fourth of July.[0003] b. Description of the Prior Art(I) SUMMARY OF THE INVENTION[0004] Sparklers are non-explosive, pyrotechnic devices which have been enjoyed for many years by both children and adults. The basic form of these devices is well-known. A rod, usually made of wire, has a coating pyrotechnic composition which extends part of the way along the length of the rod. The sparkler is used by igniting the coating of the pyrotechnic composition. Ignition results in the composition burning with a bright light, which may be of various colors depending upon the materials used in the composition. The ignition also gives off streamers of sparks, producing a pleasurable visual experience, and explaining the common name "sparkler" for these devices. The sparkling display lasts until all the pyrotechnic c...

Benefits of technology

[0006] Accordingly, it is an object of the present invention to provide a new type of sparkler which can be ignited quickly, easily, and safely with no need to provide an external source of flame. It is a further object of the invention to provide a sparkler which contains an integral ignition mechanism in the form of a match head composition tip which will allow the sparkler to be struck like a match, thereby easily and quickly igniting the coating of pyrotechnic composition.

Problems solved by technology

Heretofore, the biggest drawback to the use of sparklers has been the difficulty in igniting them.

Anyone who has attempted to do so can attest that this is often a frustrating and hazardous task.

This often results in the user's finger being burned from proximity to the flame while ignition is being attempted.

The difficulty in igniting the pyrotechnic composition appears to be the result of the hard crust on the pyrotechnic composition coating.

Aside from safety concerns caused by the need to apply a flame to the sparkler for an extended period before ignition occurs, an additional drawback is simply the inconvenience caused by the delay.

Since sparklers are often used for the entertainment of children, even such a seemingly minor delay can be magnified to the point of being a major inconvenience.
