Sealed composite package - uses case and base attached at edges by ultra sound technique separated by tearing at solder line

摘要

The package case (1) is made of K-RESIN(RTM) and the base (2) uses ABS resin. The base has an outer rim (2-4a) which is attached using ultra sound technique to the package case through a collar (1-2). The two items may be separated by tearing about the solder line. The base carries an edge groove (2-4) which engages in a feature (1-2, 1-3) located on the free edge of the case. The outer rim of the groove is in contact with the collar of the feature and assembled using ultra sound technique. ADVANTAGE - Allows use of multilayer films in composite package and permits effective recycling.
