Title: Snap-in lock retention system for a safe
Inventor: MASSETH JAMES E JR
IPC: E05B9/08
Filed: 2003-10-09
Abstract: This snap-in lock retention system allows a lock to be snap fit into an escutcheon plate in a secure mount that holds the lock irremovably in place in a proper position so that it cannot rotate or slide axially inward or outward. It eliminates the need for any fastener, since the complete locking effect is supplied by the interlocking shapes of the lock and lock socket. The lock socket has a pair of alignment flats to receive the lock in a proper orientation and an opposed pair of resilient snap locks. The resilient snap locks are free to move radially in and out by virtue of a slot that partially separates the snap locks from the rest of the escutcheon plate. The lock barrel has a cam surface leading up to the diameter that fits in the lock socket. This diameter includes a pair of alignment flats and an opposed pair of snap lock flats. As the lock is inserted, the cam surface spreads open the resilient snap locks. These pass over the retainer lip and snap into the snap lock flats where the snap locks retain the lock barrel against axial movement.

Abstract: Method and apparatus for making gusseted packages having openable and reclosable interlocking seals, the seals having male and female portions, snap detents, and formed transversely to the direction of film flow. The packaging film is provided at package length intervals with thermoformable strips secured thereto transversely to the running length of the film, and is fed to a modified standard vertical form, fill and seal packaging machine with gussets forming tooling where the film is formed into a bag with the thermoformable strips inside at the upper end of the bag, product deposited into the bag, the bag sealed, the reclosable interlocking seal formed, and the bag severed from the next bag being formed. The reclosable seal provides auditory and tactile indications of seal closing. Some packages are formed with the thermoformable strips in the gusset, and some are formed with the gusset free of strip material.
