Lids TRIZ Cases

Pivotally retractible handles and covers resolve the contradiction between ease of carrying and stackability in tool storage totes.

Segmenting the lid into functional zones reduces opening force while maintaining tamper evidence integrity through controlled separation.

A food container uses a flange support surface and base corner to maintain a vertically biased standing position.

Segmented flip lids hinge to create ergonomic handles and interlocking ribs, resolving stacking instability without adding structural complexity.

A clamshell container uses cooperating polygonal and trapezoidal seal structures to form a liquid-tight closure in a single motion.

Rotating lids align vertically to minimize footprint, resolving shipping space constraints.

Asymmetric teeth with sloped sliding faces on a child-resistant closure enable easy adult opening while preventing accidental child access.

A lift subassembly and vacuum suction cup remove individual boxes from a nested stack for automated food preparation.

A base with a depth-increasing groove holds a mobile terminal in an accommodating slot, eliminating the need to flip the structure for retrieval.

Rotating support pin prevents unintended opening by locking cap until specific angle reached, reducing part count.

A tamper evident closure uses a tear strip and snap mechanism to irreversibly indicate first opening while allowing subsequent reuse.

An upward-inward latch motion uses lever action to deform seals, balancing child resistance with senior accessibility.

A vial closure uses a movable locking tab to engage rotation-blocking stops, preventing accidental removal.

Segmented lid components allow complete disassembly for cleaning while maintaining an airtight seal against liquid food products.

A packaging device uses a shoulder depression zone to expose the lid edge for easy pivoting.

An integral living hinge merges the lid with the container body to prevent loss and leakage, ensuring reliable sealing for hot liquid consumption.

Segmentation of the lid into a large access opening and sealing flange resolves the contradiction between hermetic sealing reliability and ease of operation.

A container lid features a corner-mounted tear tab bordered by perforation lines to indicate opening.

A vanity case uses a sliding piece to open the lid when the peripheral wall bends inward under pressure.

Arcuate bottom score lines generate outward panel tension that prevents top flap sagging during repeated loading cycles.

Pre-scored cellulose blanks enable easy assembly into versatile shipping containers that transform into open display units without added complexity.

Nested rail and track locking mechanism prevents misalignment in lightweight plastic containers, ensuring secure stacking stability.

A tamper-evident container uses perforated coupling units to tear off upon opening, providing clear visual evidence of unauthorized access.

Segmented panels and dynamic side joints fold the container flat, resolving the trade-off between structural strength and shipping efficiency.

A storage display box uses a pivotable upper body and toothed portions to form two legs for inclined object support.

Breakable tabs cover lift tabs and latches to prevent unauthorized access while allowing adults to open the container by removing the tabs.

A protective casing hides the lid gripping edge, resolving the contradiction between ease of opening and child safety.

Cardboard framework fits into a peripheral groove on a plastic container to provide structural rigidity without adhesives.

Segmenting the hinge into stable and frangible parts resolves the reliability versus ease-of-operation trade-off by providing a clear visual opening status.

Segmented container slits enable precise plant positioning and increased vegetation density while preventing root damage from traditional substrates.

A hinged lid connects a cover shell to a rim, accommodating thermal expansion differences between compostable and non-compostable materials.

Trapezoidal locking structures accommodate misalignment in automated packaging, preventing container openings and product loss.

Internal recesses in the bottom frame conceal hinge lugs, resolving unauthorized manipulation vulnerabilities while simplifying assembly.

An integrated hinge structure allows screw-free assembly of a plastic storage box, reducing packaging volume for efficient transportation.

Sequential engagement of tapered ridges prevents unwanted opening while elastic flexure allows easy release and accommodates misalignment.

A frangible hinge with thumb and finger rests enables a trigger-like opening motion for plastic food containers.

Offsetting thin hinges on the cartridge receiving case prevents collision with droppage surfaces, enhancing shock resistance.

Axially arranged springs on a locking part reduce component count while securing the pump to container necks.

Relocating the locking means to the top surface protects the mechanism from transport damage while maintaining secure child safety and easy adult operation.

Segmented opening flap with locking tab prevents over-rotation and leakage by engaging a free end portion seat.

A container base integrates a mesh formation to strengthen the structure while a lid holding formation secures transport straps.

A combined lid and strainer device uses a movable cover to expose perforations for pouring paint.

Segmenting the box into hinged front and rear portions allows customers to examine products without damaging packaging integrity.

Shared sleeves and friction tabs merge multiple pizza containers into one package, reducing material waste while maintaining stacking security.

Segmented seal and closure mechanisms reduce guard profile while maintaining child resistant functionality.

Severing weakened side wall areas prevents reclosure, eliminating moisture retention that degrades stored razor cartridges.

A tamper-evident container uses a snapping device and puller to secure the cover.

An adjustable insert prevents skin formation on volatile emulsion bitumen by maintaining a continuous seal as filling levels change.
