Nestable trays are part of a pill crushing device. The trays have cylindrical midportions, spherical end portions and a planar flange. The pill crushing device has an anvil or mortar portion to engage a bottom tray, and a hammer or pestle portion to engage a top tray. The anvil portion has a recess the perimeter of which supports the bottom tray flange. A finger gap is conveniently left in the perimeter for access to the bottom tray. The hammer portion extends between two pivotable lever arms and has sufficient tolerance to allow limited independent movement of the lever arms, which in turn allows relative movement of the trays to crush pills. The hammer can contact the top tray, and may be of cylindrical form with hemispherical ends, which can itself nest in the top tray, in another version it is slightly larger and does not nest but engages the tray near the top. In a third version the cylindrical hammer has end blocks, the cylinder registers the top tray, while the blocks engage the top tray flange. Another hammer version has gripping blocks, separated by a connector tube, which have concave grooves to engage the end flanges of the top tray.
Tray for pill crushing comprising having a concave inner surface comprising a central portion having a part cylindrical inner surface joining opposed end portions having spherical inner surfaces, said inner surfaces having a first radius, whereby said inner spherical surfaces merge smoothly into said inner cylindrical surface, and a convex outer surface comprising a central portion having a part cylindrical outer surface joining opposed end portions having spherical outer surfaces, said outer surfaces having a second radius greater than the first radius by the thickness of said tray, said cylindrical surface forming a radial angle less than 180°.
A pill crushing device comprising in combination a hammer portion to engage a pestle tray and an anvil portion to engage a mortar tray, said trays being substantially identical and substantially nesting, whereby pills may be crushed between said trays.
A pill crushing device comprising an anvil portion to receive a bottom tray with a flange to act as a mortar, said anvil comprising a recess having a perimeter adapted to engage said flange of said bottom tray, and a hammer portion to engage a top tray having a flange, said trays being substantially identical and nestable, opposed paired lever arms pivoted adjacent their ends about first paired aligned first opposed pivots in said anvil portion, said hammer portion being pivoted about second paired aligned second pivots spaced apart from said first pivots on said lever arms, said hammer portion having sockets engaging connecting pins forming said second pivots, said hammer portion being rotatable from a first upper position to a second lower position, wherein said hammer portion engages said top tray, said top tray engages said bottom tray, and said bottom tray engages said recess.
