  • Patent number: 6102200
    Abstract: A security package for use in retail establishments to lock in articles which are for sale in a clear plastic case which is larger than the article displayed for sale and which optionally has enclosed an electronic article surveillance tag to prevent shoplifting. The security package has a locking mechanism built into the case which can not be opened without a key. The locking mechanism comprises a pair of asymmetric tines which are on opposite sides of an asymmetric engagement member. To lock the security package the asymmetric engagement member spreads apart the asymmetric tines until the asymmetric engagement member gets passed the asymmetric tines. The asymmetric tines close behind the asymmetric engagement member and lock the asymmetric engagement member in place. The asymmetric tines must be separated by an asymmetric key to allow the asymmetric engagement member to pass by the asymmetric tines to unlock the security package.
