Abstract: An axial piercing mechanism for a pressurized gas canister includes a housing, electric motor assembly, pushrod assembly, and lancet. The housing defines one or more radial exhaust ports and coaxial internal cavities. The electric motor assembly and pushrod assembly are disposed in the respective first and second cavities. The pushrod assembly is coupled to the electric motor assembly and is rotatably driven along the longitudinal axis thereby. The lancet is coupled to the pushrod assembly. The housing includes a second end that receives or couples to a sealed end of the pressurized gas canister proximate the lancet such that the electric motor assembly, when energized, causes the pushrod assembly and lancet to translate along the longitudinal axis, pierce a sealed end/diaphragm of the canister, and release pressurized gas through the exhaust port. A system includes the axial piercing mechanism and the pressurized gas canister.

Abstract: The present invention relates to a portable modular drainage system that is attached to a series of cylindrical planting containers. The system comprises a plurality of peaked modules with opposing, convergent curved side walls designed to conform to the curve of a planting container. Between each side wall is a notch which accepts one or more containers and firmly connects the module to the containers. The modules are preferably designed in four distinct shapes, one with quadrature symmetry for connecting four containers at once, one smaller triangular unit which connects three staggered containers, one three-legged unit that connects two containers which are positioned at an edge of a plant farm, and one edge unit designed to connect three staggered containers at the end of three rows. When these modules are appropriately connected to the containers, they effectively drain the water that would otherwise have fallen between the pots directly into the pots.
