Lids TRIZ Cases

Perforated flanges with raised bubbles deform upon separation to provide visual tamper evidence without complex mechanisms.

Solid knuckles in hollow hinges reinforce lid pivots, resolving weight-strength trade-offs while doubling molding output.

Pivoting elastic locking arms resolve complexity trade-offs by enabling flexible stacking configurations without redesigning conventional container shapes.

A detergent container lock uses a transversal wall and cam actuator to secure the lid.

An injection molded plastic ring with hook-shaped ribs adheres to container sidewalls to provide structural support without heat sealing.

Pivoting dual lids with a tongue and groove mechanism form an airtight seal, solving lid identification issues by keeping closures permanently attached.

An adjustable container uses an inner lid securement system to enable one-handed closure, eliminating the need for two hands to squeeze outer perimeters.

Relocating the locking means to the upper peripheral edge prevents transport damage and child access while maintaining intuitive consumer operation.

A lidded container uses a segmented inner ring and projected part to lock the lid without increasing the outer diameter.

Flat side walls and hinged cover reduce manufacturing complexity while enhancing seal effectiveness for dangerous environments.

A thermoformed clamshell container uses a frangible primary hinge and secondary lock to maintain lid attachment.

Deformable sealing latch sidewalls deflect under simultaneous pressure to release a child resistant enclosure lid.

A lid uses a sliding button to actuate a remote lever that lifts a flow stopper for effortless opening.

A cosmetic container cover uses a turning portion lever to press up the lid.

Integrated limiting portions and a hinged cap secure cartridges, eliminating separate caps that complicate structure.
