Abstract:
A portable land mine for training and for playing paint ball, the mine comprising:a center; a central longitudinal axis at the center of the mine; a lower base concentric with the axis, wherein the base comprises a rigid end cap forming a mine bottom that is coaxially united with a tubular portion comprising a first threaded flange; a top adapted to be concentrically coupled to the base, wherein the top comprises a second threaded flange adapted to be threadably coupled to said first flange to threadably, coaxially unite the top and the bottom of the mine; an interior formed between said base and said top adapted to contain marker fluid that is forcibly ejected from the mine upon detonation; wherein the first flange defines a shoulder for contacting with the second flange to seal the mine interior; a cartridge containing pressurized gas disposed vertically within said interior substantially coaxially with respect to said axis, said base and said top; a puncturing pin disposed proximate said cartridge for selectively puncturing the cartridge in response to cartridge movement to detonate the mine, the puncturing pin positioned coaxially relative to said axis; a detonator comprising a plunger that is coaxially, slidably mounted to said top which forces said cartridge downwardly into penetrating engagement with said puncturing pin upon sufficient contact, thereby forcibly pressuring said mine interior; and, a plurality of fluid discharge passageways defined in said top establishing fluid flow communication for venting the mine interior and directing discharged fluid.
