Caps TRIZ Cases

A two-stage molded lactic acid polymer lid adds cooling and spill-control features while overcoming the low impact strength of biodegradable plastics.

A dual-seal bottle enclosure uses an inner stopper and outer cap to prevent spills, preserve freshness, and slow temperature equalization.

A cap-integrated light source illuminates the liquid and application site in low light while switch-based activation helps conserve battery power.

A flexible hinge and interference-fit sealing surfaces help lightweight thermoformed snack containers stay leak-tight and stable.

A lid-integrated folded spoon uses score lines and minimal paperboard to stay sterile, simplify use for children, and avoid separate utensils.

Rounded lid geometry and a disposable removal inlay cut hard-to-clean areas and reduce wet wipe dispenser recontamination.

A cap with an internal stopper creates inner and outer seals to reclose open bottles, prevent spills, preserve freshness, and limit heat gain.

A stepped neck and rimmed pressing plate keep steady contact with fermented food, blocking air exposure and reducing spoilage after impact.

A spring-loaded nozzle catch seals bottle openings during storage, reducing spillage and evaporation while allowing one-handed use.

Rolled and crimped lid corners plus a slight taper remove sharp edges and let disposable aluminum lids nest tightly for shipping.

A frangible top region and puncturable seal let a straw pass through while keeping the container closed to reduce spills and leakage.

A tapered glass nests an inverted bottle with friction fit, reducing package height, spillage, and spoilage for single-serve pouring.

A dual-locking lid combines a rotatable disk and press-button lock to prevent spills while allowing controlled drinking and secure insulation.

An insulated cap with elongate-void insulation and an integrated sealing member reduces heat transfer and prevents beverage leakage.

A thermally expandable membrane creates negative pressure to seal a beverage lid, reducing spills, lid blow-off, and drinking-hole contamination.

Elastic one-piece covers conform to cut fruits and vegetables to limit air exposure and moisture loss while staying reusable.

A detent-based handle assembly lets a drinking cup rotate in fixed increments, keeping handles stable without disassembly.

An octagonal container with alternating sidewalls, grooves, and a spout-strength ring boosts crush resistance while limiting material weight and cost.

A collar-cap locking closure blocks tampering in reusable squeezable bottles while still allowing tool-assisted cleaning and refilling.

An inverted snap-fit bottle nested inside a molded wine glass cuts package height, improves stability, and enables single-pour consumption.

Segmented slots and straps keep paint tubes visible, separated, and easy to hang on an easel, reducing search time, chafing, and leakage.

A removable screen-supported chemical pack keeps a fixed nozzle distance, reduces clogging, and limits user contact during replacement.

Keeps drink ingredients and supplements separate until mixing by using interlocking containers with interchangeable lids for easier on-the-go management.

An inward-tapered neck and sealing ring remove sterilant-trapping gaps, enabling immersion sterilization without residue on food-contact surfaces.

Separate chambers and detachable couplings keep harsh and mild liquids apart until drinking, enabling cleaner sequential consumption.

A shrink sleeve and vented tapered dosing cup prevent cup separation, enable scent sampling, and support one-handed dispensing.

A movable lid seal rotates into a cleaning position, exposing trigger and drink-aperture surfaces without disassembly for better hygiene.

An over-center latch separates dispensing from sealing to prevent leaks and spillage in liquid container closures under pressure or impact.

A lateral and longitudinal clearing mechanism removes used items from a paper roll insert while preventing uncontrolled sliding and loose fit.

Integrated lid projections retain a utensil outside the product while a stay-open closure improves one-handed dispensing and reduces contamination.

Multiple annular ribs, a gripping rim, and an indented channel help beverage lids seal securely, resist spills, and stack stably.

A glass insert inside a polymer shell prevents chemical leaching, reduces breakage risk, and stays easier to handle after microwaving.

A pivoting upper flask section locks into a leak-proof seal yet opens wide for easier interior cleaning and dishwasher-safe washing.

A hinged door and angled flange let single-serve beverage filter containers be refilled, resealed, and reused while keeping contents fresh.

A button-actuated stopper and air vent let users drink one-handed while the lid automatically reseals to prevent spills and heat loss.

Aligned cup and lid wings plus visual, audible, and tactile cues help caregivers and toddlers tighten spillproof cups correctly.

A bellows sealing ring lets one food processor lid fit different bowl rim heights, including nested bowls, while maintaining a secure seal.

A rigid-center, soft-rim lid compensates for grinder container height tolerances to keep coffee powder sealed and reduce contamination.

A rotating seal assembly shifts from use to cleaning position, improving access to drink apertures without lid disassembly or loose parts.

Pivoting sip and straw closures let one beverage lid switch consumption modes while keeping each opening sealed to prevent spills.

A lid-mounted aroma pod routes air through dry aromatic material so drinkers inhale scent during sipping without wetting or power.

A rotating slider lid simplifies container dispensing while preventing residue buildup and maintaining a secure fluid-tight seal.

A shrink sleeve secures the dosing cup during handling while a vent opening lets consumers smell the scent additive without spills.

A grooved lid, annular projection, and separate scoop retainer improve locking, limit powder buildup, and reduce contamination.

A snap-fit lid and sieve reduce shaker parts while enabling quick supplement mixing and dissolution without a stable surface.

A removable lid-mounted handle stays out of the heat, then locks back into place for secure Dutch oven lifting without extra tools.

A pivoting spout cover and tunnel-enclosed push button improve bottle lid durability while reducing hinge pinching and reattachment issues.
