Abstract: A tamper-resistant, caplet like medicament that masks the taste of poor tasting drugs and possesses an improved lubricity for easier swallowing is produced by shrinking a gelatin-based capsule about a caplet-shaped tablet of the medicament at specific temperatures, pressure and relative humidity.

Abstract: An apparatus for coating molds to make hard gelatin capsules has a dish for holding a bath of liquid gelatin. A multi-well tray is submerged in the bath to establish a plurality of fluid passageways through the bath and to create a pool of liquid gelatin in each of the wells. A drive unit, having a pair of counterrotating gears, moves gelatin through the passageways and pools to maintain a substantially uniform gelatin temperature throughout the bath. Capsule molds are periodically submerged into the pools and then withdrawn to manufacture the hard gelatin capsules.

Abstract: Method and apparatus for sealing gelatin capsules having cylindrical cap and body portions arranged in telescoping relationship to contain a medicament therein comprising a capsule-sealing machine for continuously conveying capsules from a supply hopper to a capsule-rectification station wherein the capsules are reoriented and delivered in endwise, cap-down abutment to capsule-wetting stations where a suitable sealing liquid is applied to the capsules at the seams of their cap and body portions to be located between the overlapping side walls of the cap and body portions of the capsules, and wherein the capsules are conveyed from their wetting stations in peripheral pockets of a rotating drum dryer to a capsule heating and sealing section where the capsules are heated by convection and conduction to seal the cap and body portions.

Abstract: Improved method and apparatus for use in sealing gelatin capsules filled with medicinal ingredients wherein each capsule has a generally cylindrical cap and body arranged with the side wall of the body telescopically within the side wall of the cap to contain the medicament therein comprising an economical and compact wetting device for automatically conveying filled capsules from a capsule-filling machine by pneumatic pressure conveyance through one or more passageways to a wetting location where each capsule is maintained in a generally cap-upright position and metered amounts of a wetting liquid are applied to side wall portions of the body of the capsule adjacent the seam of the cap and body to pass by capillary action into the space between the overlapping cap and body side walls, and the capsules are released from wetting positions in the passageways for further pneumatic conveyance to a point of heat treatment for final sealing of the body and cap portions of the capsule to prevent their separation and
