The two telescoping halves of a capsule made of a thermoplastic material, such as rigid gelatin, are securely joined to one another. In one embodiment this involves partially detelescoping the capsule halves, rendering a portion of the capsule in the previously telescoped region tacky, eg by heat or solvent, and retelescoping the halves with relative spining or axial oscillation of the halves. The halves may also be spin welded. |
