View Patent ↗A method is disclosed for the sealing of hard shell capsules having coaxial body parts which overlap when telescopically joined. Also described is an apparatus to seal the capsules. The method comprises the steps of holding the capsule in a precise and upright position and injecting a quantity of sealing fluid in the overlap of the body parts. An apparatus for performing the method is also disclosed. The apparatus comprises a sealing clamp to hold the capsule in an upright position and means to inject the sealing fluid in the overlap of the body parts.
1. A method of sealing a hard shell capsule having coaxial body parts which overlap when telescopically joined, the method comprising the steps of:
using a sealing clamp to clamp and hold the capsule in a precise and upright position, wherein the sealing clamp has at least two parts;
injecting a quantity of sealing fluid in the overlap of the joined body parts;
releasing the capsule; and
wherein the capsule is made of materials that are pharmaceutically acceptable with respect to their chemical and physical properties.
2. The method of claim 1 , wherein an excess of sealing fluid is removed from the outside of the capsule.
3. The method of claim 2 , wherein the excess of sealing fluid is removed from a clamp holding the capsule in the upright position.
4. The method of claim 1 , wherein an excess of sealing fluid is removed from a clamp holding the capsule in the upright position.
