should preferably be fda approved and sufficiently non porous to be cleanable to u201c 3 a u201d sanitary standards or u201c 3 a ssi u201d an ideal material also should be transparent to x rays and or metal detectors so as permit inspection of the interior of the hopper 20 during shipment urethane is acceptable for all of these purposes however other castable and even injection moldable materials would be suitable for some or all of these purposes as well the hopper 20 as a whole provides at least a 50 cost reduction when compared to a stainless steel hopper of equal capacity and capabilities referring now to fig1 3 the hopper body 40 is generally frustoconical in shape so as to have a relatively small lower dispensing opening 44 that receives the tool 34 and an open upper end 46 that is closable with the lid 42 the uppermost end of the hopper body 40 is cylindrical for mating with the lid 42 as detailed below the hopper body 40 is formed from two hopper body sections 48 and 50 and thus is u201c split u201d vertically down the center the hopper body sections 48 and 50 may be cast.
