Method for sealing non-enteric capsules

Abstract

A method is disclosed for sealing edible capsules comprised of telescopically engaged tubular capsule halves that define a junction seam between them. The method comprises adhesively applying against at least a portion of the seam a frangible, edible label adapted to cover the seam at the point of intersection therewith, and to fracture upon slight displacement of the capsule halves with respect to each other. In one embodiment, the present method comprises the preparation of individual labels, the application to such labels of a quantity of adhesive and the subsequent application of the labels to the capsule. In an alternate embodiment, the labels, comprising a film forming material, are directly applied to the capsule by the projection of a hot melt of the film forming material onto the capsule at the location of the seam. The method may be practiced by means of automated label applying machinery, in the instance of the prior preparation of the labels, and by jet printing techniques in the instance of direct label application. The labels may also be imprinted with suitable indicia, either before or after application to the capsule. The capsules sealed and labeled in accordance with the present method exhibit improved tamper evidence and resistance, as the labels are incapable of cosmetic reconstruction after tampering. In the instance where the label comprises a longitudinal strip extending annularly about the entire capsule seam, the resulting capsule is advantageously rendered fluid-tight.
