Abstract: Aspects of the present invention are directed to a child-resistant container comprising a lid and a vial. The lid has a side wall, an inner surface and a lid cover. The lid cover includes a top, a bottom, and a front surface and at least two lid hooks protruding from the bottom surface. The vial contains an opening accessing a cavity and a rim extending around at least a portion of the opening, the rim having at least two moveable tabs partially affixed to the rim and movable about a pivot point. The movable tabs contain tab hooks above the pivot point for engaging with the lid hooks to secure the lid cover to the vial. The moveable tabs are displaceable outwardly away from the lid to disengage the tab hooks from the lid hooks by pressing inwardly on the moveable tabs below the pivot point.

Abstract: In accordance with the present invention a piece of perforated tubing is formed into a series of loops which define a generally truncated shape with at least one large diameter loop at the top and at least one smaller diameter loop located below the top loop. The tubing has sufficient strength and is wound into a contour shape to fit around the root ball of a tree or shrub harvested from a nursery. Ther perforated tubing includes a plurality of longitudinally spaced openings of a size sufficient to supply water and/or fertilizer to the root ball after the root ball is planted in the ground. Means are provided to maintain the tubing in the truncated shape. In one embodiment this shape comprises a series of specially fixed wound loops. In one embodiment this comprises formed loops with six connection points where the loops contact one another. Means are provided for supplying water and/or fertilizer to the tubing after the root ball has been planted.

Abstract: A convertible open top hopper car (10) is assembled by longitudinally aligning a pair of railway car stub sills (12) in an assembly position. Transversely extending shear plates (16) are attached to each stub sill. A transversely extending inclined locating plate (18) is integrally connected to the inner end portion of each stub sill. The locating plate preferably includes a flange portion (22) adapted to receive a desired hopper car bottom (24). The bottom may be a conventional gondola bottom having pivoting doors, a light weight gondola bottom for use in cars which are rotated 180.degree. to unload the lading, or a gondola bottom having rapid discharge doors. The bottom selected for application is preferably first attached at each of its ends to the longitudinally spaced locating plates (18). Then hopper car sides (40) including side sills (42) and side sheets (46) are lowered onto the respective shear plates (16) and are welded to the shear plates.
