Caps TRIZ Cases

Breakable thread connects cap and base to prevent ingestion of detached parts.

Angled waste container design with fork-receiving sleeves prevents spills during transfer to removal vehicles.

Expandable gaps in retaining and positioning devices automate cap feeding, eliminating multiple stations and operator intervention.

A bayonet closure system centers a floating sealing means within the drain opening to decouple locking forces from fluid-tightness.

A sealing overcap uses a flexing plug to engage the container rim for a secure frictional seal.

A resealable cap snaps onto a plastic container rim to maintain freshness without flexible membranes.

A reversible stopper seals the dispensing nozzle orifice to prevent fluid drain-back, eliminating medicament precipitation and re-priming requirements.

A marble-sealed bottle uses a twistable cap and plunger to release the sealing element for easy access.

Low-temperature autoclaving joins sealant to flexible membrane via internal pressure, preventing thermal degradation and toxic byproducts.

An elastic barrier film expands and contracts under retort pressure changes, maintaining seal integrity while preventing product contamination.

A smart capsule transponder integrates a breakable leg circuit to detect tampering while preserving data access.

Segmented hinge connections and bayonet locking mechanisms enable a wide opening angle and high pressure sealing for carbonated beverage containers.

A reclosable container uses a slide mechanism and frangible tear strip to secure the cover portion in a closed position.

A synthetic resin cap uses a thin wall portion to deform under pressure and release internal gas.

Angularly spaced stops guide the cap thread axially, eliminating removable rings and reducing torque for reliable sealing.

A closure cap integrates a hinged safety element that seals the container rim and signals tampering through a breaking film hinge.

Segmented vertical and horizontal tubes in a bottle neck prevent leakage while ensuring smooth fluid flow regardless of orientation.

Unscrewing the closure tears a weakened portion, causing the ring to pop out and display contrasting colors for clear seal violation detection.

A flexible diaphragm in a closure assembly deflects to equalize pressure without creating openings that cause liquid leakage.

Rotating the top portion drives a screw thread mechanism that linearly displaces a partition wall, adjusting compartment volumes without direct hand contact.

A closure cap uses a pivoting part and tear-open segment to lift the container lid.

Variable thickness internal skirt reduces shrinkage marks on cosmetic caps by enabling uniform cooling.

An annular bead prevents skirt wall deformation during wrap-seaming while a pressure release line vents gas.

A resin bottle cap end-ring uses a non-barbed guidance section and flange cut-out to tilt the ring for easy removal.

A portable voice therapy device uses a flexible phonation tube to bubble water for vocal training.

Molded protrusions guide slit formation in double containers, enabling reliable air intake without inner layer damage.

Deformable sealing material fills cavities beneath jagged crown cap ends, preventing mold growth and contamination during container filling operations.

A pouring device secures its cap assembly via a retaining band extending radially to a spout fastening element.

A motor and gear assembly with a light read module filters ambient interference to improve sensor accuracy.

A spinning collar cap assembly uses a threaded interface between an overcap and a rotatable collar to secure container contents.

A unitary closure merges a natural cork core with a threaded cap to enable effortless manual opening.

Inverting vent hole protrusions outward prevents liner catching and damage while maintaining pressure release functionality.

A sliding plug moves between open and closed positions within a universal connector assembly.

A heat-shrinkable plastic capsule covers a metal screw stopper to provide visible tamper evidence upon removal.

A tamper evident container uses a segmented snap-lock closure with an outward tear strip to secure contents.

Segmented shafts adjust distance compensation without complex container tracking, reducing maintenance effort.

A container closure body uses rim cavities and teeth to rotate during demoulding, enabling core extraction without side-cores.

A multimodal high density polyethylene composition incorporates a saturated amide slip agent to deliver low friction and mechanical strength.

Radial compression of a plastic insert seal against the bottle neck maintains constant unscrewing torque despite dimensional variations.

Pre-assembled closure parts enable sterilization fluid to reach all contact surfaces, reducing the need for multiple aseptic stations.

An adjustable cap assembly uses a ratchet mechanism to secure an outer plastic closure onto an inner sleeve, ensuring a tight fit on the container neck.

Two-ply closure separates a sealing panel to reveal an inner integrity indicator.

Segmented external threads prevent wall thickness aggregations during injection molding, eliminating leaks from nonhomogeneous rigidity in gravity cups.

Differential leg lengths balance snap-fit strength and installation ease, resolving the trade-off between secure anchoring and assembly difficulty.

A cap body uses a polyester resin coating film with hydrocarbon-based wax to lower friction on the inner surface.
