ABSTRACT:
A sonorous alarm system to be placed in briefcases and small valises will permit the person who uses the same to have an opportune warning in the case that someone non-authorized tries to carry with him the small valise when the proprietary has it on the floor. Additionally, the alarm can also be generated when someone non-authorized tries to carry with him the small case by sliding it on the floor. As a complement, the system can be provided with alarm generating means operated when the small case is opened. The sonorous alarm will be generated in each of the foregoing cases and will be heard at several meters in the surrounding space. The proprietary is able to energize the alarm generating means by pushing one (or several) exterior push-buttons.
