Abstract
A gelatin capsule sealant of a water soluble, amide-containing polymer adhesive in a volatile, essentially non-aqueous solvent is used to seal gelatin capsule sections together at less than the entire circumference of overlap between the capsule sections. The sealant may also adhere a pharmaceutical caplet within the capsule to the internal wall of the capsule. The method of applying the sealant to the capsule sections and possibly also the pharmaceutical caplet uses a drop of the sealant spread at the junction of an eccentric arcuate portion of the sections and the pharmaceutical caplet. The solvent evaporates from the sealant through the portion of the capsule section overlap not sealed. The sealant may use 'generally regarded as safe' (GRAS) solvents and may also include a GRAS dye for visual indication tha that the capsule is eccentrically sealed to resist manually forced separation of the capsule sections.
