Self-Lock (Double-Lock) Capsules
There is a lock ring on the cap as well as on the body. There are also 2 – air vents at 180° opposite to each other provided on the body to release air pressure developed during filling and locking operation on filling machines. The closed joined length of the filled capsule is within a narrow range of tolerance for these types of capsules. The capsule-filling machines are set as per the standard specifications of the customer for Joining Length. If capsules are locked beyond the Joining Length, denting or partial locking may occur which results in defects or release of medicament on the vibrator of the packing machine.
