Label holder for closing and sealing bags and the like, and security seal suitable for use therewith

摘要

Label holders used for closing and sealing bags have the disadvantage of having to be individualized (numbered) since one type of violation would be destroying the label holder to withdraw the security seal intact and then substituting it with a new label holder and re-using the seal. The label holder of this invention has two protuberances formed with rectangular openings on one portion thereof, which pass through two corresponding openings in the other portion when the label holder is closed. Two stops, one on each side of the strip of the outer surface between the two corresponding openings are provided. The security seal has a capsule and a lock interconnected by a thread, which in the sealed configuration are separated by the first protuberance, a part of the lock passing through the opening in such protuberance and a head of the lock being locked within the capsule. The part of the lock is connected to the head by weakenings. A blade projecting from the capsule has a free end which passes through the opening in the other protuberance and is formed with a lateral projection which engages behind such protuberance.
