An improved, multiple-use fireworks launcher (10) is provided for the launching of fireworks such as an artillery shell (40) having a lower lift charge (42) and an upper effect charge (44). The launcher (10) includes a base (12), with an upstanding, open-top launch tube (14) operably coupled with the base (12). A reinforcing section (16) is positioned about the lower end of launch tube (14), and preferably comprises a tubular sleeve (36) tightly secured to the outer surface (32) of launch tube (14). The combined thickness of the tube (14) and section (16) are sufficient to prevent catastrophic failure of the launcher (10) in the event a shell (40) is improperly placed within the tube (14) in an inverted condition with the lift charge (42) thereof positioned over the effect charge (44).

1. A fireworks launcher operable to launch a fireworks artillery shell having a lift charge and an effect charge, said launcher comprising: a base;an elongated, upright launch tube secured to said base and configured to receive said shell, said launch tube having a tubular wall presenting an uppermost open end remote from said base, an inner surface and an outer surface, and a tubular wall thickness between said inner and outer surfaces; anda reinforcing section extending upwardly from said base and having an inner surface in engagement with a portion of said outer surface of the tubular wall of the launch tube above said base,said launch tube being operable to permit ignition and launching of said shell when properly placed within said launch tube with said lift charge beneath said effect charge, the combined thickness of said tubular wall and said reinforcing section being sufficient to withstand potentially destructive forces generated within said launch tube in order to maintain the structural integrity of the launcher, in the event that said fireworks artillery shell is improperly placed within said launch tube and ignited in an inverted condition with said lift charge disposed above said effect charge. 2. The fireworks launcher of claim 1, wherein said reinforcing section is integrally molded with the launch tube. 3. The fireworks launcher of claim 1, the inner surface of said tubular body being adhesively connected with said tubular wall outer surface. 4. The fireworks launcher of claim 1, wherein said tubular wall and said reinforcing section are formed of high density polyethylene. 5. The fireworks launcher of claim 1, wherein said reinforcing section is positioned in abutting contact with said base. 6. The fireworks launcher of claim 1, wherein said reinforcing section has a height which is at least about 20% of the total height of said tubular wall. 7. The fireworks launcher of claim 1, wherein said combined thickness of said tubular wall and said reinforcing section is at least about 40% greater than said tubular wall thickness. 8. The fireworks launcher of claim 1, wherein the reinforcing section has a height which is from about 25% to 50% of the total height of said tubular wall. 9. The fireworks launcher of claim 1, wherein said combined thickness of said tubular wall and said reinforcing section is about 45% to 70% greater than said tubular wall thickness. 10. A fireworks launcher operable to launch a fireworks artillery shell having a lift charge and an effect charge, said launcher comprising: a base;an elongated, upright launch tube secured to said base and configured to receive said shell, said launch tube having a tubular wall presenting an uppermost open end remote from said base, an inner surface and an outer surface and a tubular wall thickness between said inner and outer surfaces; anda reinforcing section extending upwardly from said base and in surrounding relationship to a portion of said outer surface of the tubular wall of said launch tube above said base, said reinforcing section comprising a tubular body having an inner surface in engagement with said tubular wall outer surface,said launch tube being operable to permit ignition and launching of said shell when properly placed within said launch tube with said lift charge beneath said effect charge, the combined thickness of said tubular wall and said reinforcing section being sufficient to withstand potentially destructive forces generated within said launch tube in order to maintain the structural integrity of the launcher, in the event that said fireworks artillery shell is improperly placed within said launch tube and ignited in an inverted condition with said lift charge disposed above said effect charge. 11. The fireworks launcher of claim 10, wherein said tubular wall and said reinforcing section are formed of high density polyethylene. 12. The fireworks launcher of claim 10, wherein said reinforcing section is positioned in abutting contact with said base. 13. The fireworks launcher of claim 10, wherein said reinforcing section has a height which is at least about 20% of the total height of said tubular wall. 14. The fireworks launcher of claim 10, wherein said combined thickness of said tubular wall and said reinforcing section is at least about 40% greater than said tubular wall thickness. 15. The fireworks launcher of claim 10, wherein the reinforcing section has a height which is from about 25% to 50% of the total height of said tubular wall. 16. The fireworks launcher of claim 15, wherein said combined thickness of said tubular wall and said reinforcing section is about 45% to 70% greater than said tubular wall thickness. 17. A fireworks launcher operable to launch a fireworks artillery shell having a lift charge and an effect charge, said launcher comprising: a base;an elongated, upright launch tube secured to said base and configured to receive said shell, said launch tube having a tubular wall presenting an uppermost open end remote from said base, an inner surface and an outer surface and a tubular wall thickness between said inner and outer surfaces; anda reinforcing section extending upwardly from said base and in surrounding relationship to a portion of said outer surface of the tubular wall of said launch tube above said base, said reinforcing section comprising a tubular body having an inner surface in engagement with said tubular wall outer surface, wherein said reinforcing section has a height which is at least about 20% of the total height of said tubular wall,said launch tube being operable to permit ignition and launching of said shell when properly placed within said launch tube with said lift charge beneath said effect charge, the combined thickness of said tubular wall and said reinforcing section being sufficient to withstand potentially destructive forces generated within said launch tube in order to maintain the structural integrity of the launcher, in the event that said fireworks artillery shell is improperly placed within said launch tube and ignited in an inverted condition with said lift charge disposed above said effect charge. 18. The fireworks launcher of claim 17, wherein said tubular wall and said reinforcing section are formed of high density polyethylene. 19. The fireworks launcher of claim 18, wherein said reinforcing section is positioned in abutting contact with said base. 20. The fireworks launcher of claim 17, wherein said combined thickness of said tubular wall and said reinforcing section is at least about 40% greater than said tubular wall thickness.
