Caps TRIZ Cases

A frangible vertex hinge connects the lid and base of a plastic food container, enabling easy pinching to open.

A movable plug seals the dispensing passage, preventing oxidation and residue buildup in cosmetic packaging.

Tapered sidewalls in a rigid container maintain the fluffed appearance of sliced meat by minimizing compression and shifting during storage.

Vented cap maintains closed environment for enteral feeding material while allowing air compensation to prevent contamination.

An over-cap device secures a container cap using snap fit mechanisms.

A tamper-evident ring uses snap portions to engage complementary formations on a closure neck, securing the ring within an inner space.

Segmenting the lidstock seal into a positioning locus and a hermetic flange bond resolves the trade-off between handling stability and user removal ease.

Pre-forming the tamper-evident band during molding eliminates complex downstream scoring steps while maintaining reliable container security.

A medicine bottle closure uses a segmented band with internal lips to secure the screw cap.

Thermoplastic polymer film melts with paraffin wax to enable direct blending into bitumen compositions.

Replacing threaded fastening with cam surfaces cuts plastics consumption and weight while maintaining secure closure.

Segmented cap protrusions engage rim notches to prevent child access while visual indicators align for adult opening.

A urine detection cup lid uses an elastic element to generate an acoustic signal upon proper sealing.

Segmented compartments with plunger members enable selective additive dispensing while reducing structural complexity.

Merging the cap and seal into one assembly eliminates separate installation steps, reducing process complexity while maintaining air prevention.

Segmented snap-fit mounting rings and hinged lids reduce application time while maintaining secure seals on wide-mouth and narrow-neck containers.

A filler neck cap vacuum-relief regulator opens to admit make-up air when high vacuum conditions are detected.

Segmented cap components with nested engagement structures prevent accidental release and contamination in clean room chemical handling.

Flexible windows in the overshell accommodate carbonation pressure, preventing seal failure and preserving beverage freshness without compromising child safety.

External rotation stops on the oil pan provide tactile feedback during manual tightening, preventing thread damage in soft materials.

A flip-top closure integrates a lateral actuation button with a vertical locking tab to secure the lid.

A child-resistant closure uses a flexible shoulder to generate upward biasing force on the dosage cap.

A membrane seals an open spout on a food package, preventing external contamination through the neck interface while maintaining recloseability.

A modular fluid container uses frangible barriers to isolate distinct beverage components until user activation triggers mixing.

A stick-spout-pouch assembly holds liquid confection in a sealed bag attached to a rigid stick.

Segmented elastomeric sleeves absorb shock while apertures preserve label visibility.

An integrated bottle cap seals liquor bottles while providing accurate 1-ounce measurement, eliminating separate jiggers and reducing bar clutter.

Segmented cap portions with asymmetric teeth and a kiss-cut seal prevent tampering evidence replacement without complex manufacturing.

Raised pads create ventilation gaps between the cap and bottle neck to release product aroma without external scratch pads.

A conically shaped lid creates a mechanical buttress against container sidewalls to prevent sample leakage under pressure differentials.

A prescription drug lock box uses a mechanical combination cover to secure contents without electronics.

A closure assembly couples a lid to a container via a flexible tethering element and rupturable bridges.

An integrated closure member uses a heating conduit and solenoid valve to circulate coolant, preventing urea freezing in vehicle exhaust systems.

Segmented bushing and housing components replace adhesive bonding to prevent leakage damage while maintaining secure mechanical attachment.

A case sealing apparatus uses movable side conveying units and vertically adjustable tape head assemblies to handle various case dimensions.

A capping device with an articulated lower ring and cap assembly enables axial displacement and pivotal movement.

A cap liner combines mineral-filler polyolefin and porous foam to seal bottles while venting gas.

Segmentation and intermediary principles resolve the trade-off between child safety and ease of operation by adding a tear-away tamper-evident layer.

A crown-type metal cap with a convex arc peripheral lip aligns concentrically to seal aluminum bottle mouths.

A cap assembly depresses a deformable reservoir surface to pierce the membrane and release beverage into the container.

An axial separation mechanism replaces radial security rings, eliminating incomplete extension and visible tearing lines.

A plastic closure system uses a floating lid and retainer ring to seal containers during sterilization.

Inner skirt cut-outs enable greater outer skirt deflection to disengage the locking means, balancing adult accessibility with child resistance.

Segmented spout vents enable pressure equalization within sealed pouch cavities, preventing structural rupture during high-pressure processing.

Segmented finger rings attach to bottle caps using flexible connectors, preventing accidental drops without deforming wrapping plastic.

A signal model separates orientation data from parasitic noise in tube component alignment systems.

Rotatable rolling elements replace sliding contact in capping machine ejection heads, reducing wear on the sliding profile.

A bayonet closure cap uses guide ribs to engage an anchor ring, maintaining attachment during opening.

Extraction of closure markings eliminates protruding support rings, resolving the contradiction between measurement precision and device complexity.
