Caps TRIZ Cases

A resilient tether band keeps the screw cap attached, compatible with existing capping machinery, and stable away from the spout during pouring.

A tethered lid and temporary locking position keep the cap attached, reduce strain, and prevent pouring outlet interference.

Deformable connecting bands let a tethered bottle cap stay open without special molds, reducing accidental reclosure and user interference.

Permanent disruptions in a closure seal keep gas pathways open under torque and heat, preventing container pressure imbalance.

A sealed adapter and check-valve enable spill-resistant lubricant transfer from a shipping container directly into an equipment reservoir.

A tethered tab and frangible band keep the cap displaced from the container opening, reducing user interference during drinking.

A rotatable cap and anchor ring keep the carton closure attached after opening while the tamper indicator changes state before piercing.

An annular clamping element locks a removable glass inner container in a glass pot, simplifying refill and recycling while reducing plastic use.

An exchangeable gripper cartridge and independently driven heads speed multi-tube capping and de-capping while reducing downtime.

A unimodal HDPE resin balances stiffness, yield strength, creep resistance, and injection-molding processability for cap and closure devices.

A silicone cap with a reduced inner diameter seals opened caulk tube tips tightly to block air and moisture and keep remaining caulk usable.

A snap-fit stopper, cover, and tear-off blocking ring seal fluid vessels, show first use, and avoid metal contamination in high-rate assembly.

Side-air injection pushes caps along channel edges instead of the bottom, preserving orientation while reducing jams and air demand.

Interlocking ribs and a spherical protrusion keep a cosmetic pump lid secure, openable by lifting, and resistant to leakage from co-rotation.

Complementary cap and tool engagement features align the cap before threading, reducing misalignment, thread damage, and sealing defects.

Differential surface tension openings let liquor and chaser stay separate in one bottle, then dispense selectively by rotating the container.

A nested inner and outer cap with a frangible safety strip preserves tamper evidence while adding active material control on standard screw-neck containers.

An extension strip and U-shaped tether keep the bottle cap attached after opening, reducing cap loss while supporting easy use and recycling.

Elastic projection pieces and support protrusions let a decorative outer cap install easily, grip well, and resist rotation or appearance damage.

Integrated gripping arms and collar-engaging teeth keep containers aligned and rotation-free across varied neck formats during capping.

A tilted annular wall and press-in sealing structure let paper containers seal reliably, stack efficiently, and be filled without specialized equipment.

An elastic locking body and deforming unit secure bottles without recesses, reducing wear, dirt buildup, and slippage in carrousel machines.

A cylindrical capping head with swing-shaft through-holes cuts weight and complexity while preserving strength and biasing performance.

Elastic tongues and thread interruptions create clear closure clicks on glass containers without neck protrusions that hurt appearance or manufacturing.

Two synchronized capping groups handle deformable and rigid caps without complex changeovers, improving precision, flexibility, and reliability.

Curved-rupture tethers act as torsion bars so the cap stays attached, opens with lower resistance, and locks stably in the open position.

Non-converging incision lines guide tether unfolding so the closure stays attached yet holds open without blocking pouring or drinking.

A locking ridge and collar keep a tethered package lid securely closed, preventing accidental opening, spillage, and littering.

Segmented seal zones let a container lid keep strong rim adhesion for freshness while breaking predictably for pull-tab opening.

Thermoformed PET or PEF dome caps replace HDPE or PP closures to avoid PET stream contamination while maintaining sealing and gas barrier performance.

A fixed plug insert with a valve or baffle prevents inverted pouch leakage while the removable plug keeps aseptic filling unobstructed.

Shaped conveyor cleats use convex and concave edges plus gravity to return misoriented crown caps before downstream handling.

A pierce-in flange, nut, and cap turn flexible containers into resealable pour outlets that limit moisture uptake, clumping, and tearing.

An integrated press-tab and breakaway tamper disc helps pill containers stay child-resistant while clearly showing opening and supporting accurate dispensing.

Living hinges and malleable walls let this reusable beverage container collapse for compact storage while the cap locks the folded shape.

Multiple close contact portions form a closed sealing curve at the container inlet to block air, moisture, and bacteria without extra seals.

An RFID-enabled closure lid combines sterile sealing, tamper evidence, and individual container tracking for safer medicament filling and logistics.

An elastic security ring guides a tethered cap beside the container mouth, keeping it attached without blocking use or falling back.

Sterilized ROPP caps inside an isolator simplify aseptic aluminium and glass filling while reducing cleaning time, energy use, and maintenance.

A tethered dispensing cap creates a closed enteral feeding pouch connection to limit contamination, oxidation, and spillage.

Segmented skirt sections let a lip engage the circumferential flange, balancing easy removal with leak-proof sealing under pressure.

Vertical offset between latching lugs accommodates deformation and misalignment, enabling firm, leak-tight reclosure without excessive force.

A pre-positioned extension abuts the container A-collar to guide axial breakage and prevent band rotation during opening.

See how a pre-loaded resilient member expands inside a cap to absorb freezing-driven volume changes while maintaining a secure container seal.

A lid, spacer, protrusion, and membrane enable repeated compound dispensing while preserving a sealed cap between uses.

An inner and outer cap use a helical groove, elastic prolongation, and breakable means to show first opening and resist refilling.
