Closure Caps TRIZ Cases

A hinged bottle safety lid uses a protrusion to retain the closure cap beyond 180 degrees for stable pouring.

Flexible retention wings on a double-walled cap cover snap-lock around the cap rim, preventing disengagement and loss during use.

An integrated cap and spacer ring prevent premature lid perforation during storage by keeping the punch away from the seal until initial use.

Dual anti-rotation rib and stop cam secure the cutting element within the spout base.

A sliding closure assembly with a disc cap and arcuate monorail enables horizontal movement.

A twist and flip closure uses a locking tab and frangible band to secure containers while maintaining an integrated structure.

A threaded joint structure attaches a replaceable decorative top to a flip top lid base unit.

Relocating the humidity control substance to the cap prevents accidental ingestion and physical damage from container movement.

Segmented timer and vent systems resolve measurement precision versus device complexity contradictions in liquid dispensing.

A dispensing valve features a reduced-size discharge end for precise fluid flow control.

Segmented thread ribs on the lid and base allow rapid closure without precise alignment, resolving the trade-off between secure fastening and ease of operation.

A retractable cover system uses a translational cam mechanism to drive an elastic-biased cap along a longitudinal axis for one-handed operation.

A capping device uses a protruding portion to lock the cap in a tilted open position.

A hinged closure cap integrates a desiccant chamber and a single-loop spring element to secure products within the container body.

Elastic perimeter swellings on a plastic liner fasten it to a glass shell, enabling clean separation of materials for recycling.

Brush rod guide member with tapered tubes stains pearl powder onto the brush, eliminating wastage from direct finger application.

A container cap resin composition uses acid-modified polyolefin to bond m-xylylene polyamide with a polyolefin matrix.

A closure integrates a hinged tamper element that bends away from the cover to signal initial opening.

Segmented bodies enable repeated re-closure without breaking rings, maintaining gas retention in beverage containers.

A food jar vent mechanism equilibrates internal air pressure with the atmosphere, preventing vacuum formation and food spray during lid removal.

An integrated lid structure merges screwing threads and a hinge via helical grooves, resolving complexity trade-offs while ensuring reliable closure.

Segmented closure design prevents ring detachment during tab removal, resolving stability contradictions while providing clear visual tamper evidence.
