Flexible Containers TRIZ Cases

Die-wall projections form tactile outer relief on can blanks while keeping the inner surface smooth for easy filling, emptying, and low residue.

A vented laminate container uses a support frame and squeeze-open dispenser to cut material use while maintaining structural integrity.

Curved, folded end edges and a joint member improve tube-container joining strength while keeping the package compact for transport and display.

A shoulder groove absorbs pressing force in a squeezable container, keeping the discharge part round and reducing cap-area leakage.

A liquid-filled outer tube transmits pressure evenly to an inner product tube, enabling one-hand dispensing even as contents run low.

A steep annular shoulder face creates space for weld material flow, letting one tube head fit multiple skirt thicknesses with a flush finish.

A tube head with a shoulder angle above 125° fits flexible skirts of different thicknesses while keeping the weld flush and visually clean.

A single integrated indexing mark on the tube head replaces separate orientation parts, improving sleeve alignment while reducing plastic use.

A removable shape-retention member keeps the folded inner section upright, enabling flat storage, simple assembly, and repeated box reuse.

Film-laminate support frames help disposable flexible containers stand upright while reducing material use and production cost.

Cavity-filling sealing material melts during welding to close voids in cellulose tubular packaging and improve leak-proof performance.

Varying sheet thickness guides thumb-and-index-finger squeezing to expel contents completely, while food-grade plastic isolates air for freshness.

A two-handed tube squeezer uses pivotable frames to divert the squeezed portion away from the user's hand.

An internal stiffener supports thin-walled containers while a locking collar secures a plug via interference fit, preventing leakage and collapse of weak materials.

A multi-layer polymer container uses a foamed inner layer to reduce weight while an outer film layer maintains surface quality.

V-shaped grooves between the body and shoulder portions allow efficient content discharge without excessive compression force or neck deformation.

Aligning roller axes with the folding mechanism generates self-locking force, eliminating holding torque and reducing user effort during emptying.

An inflatable bladder pressurizes a flexible tube to expel contents through a mouthpiece channel, eliminating messy manual squeezing.

A U-shaped bracket attached to molded nonwoven fabric walls provides dimensional stability and aesthetic appeal for storage crates.

Hinged articulatable portion extends tap through small box opening, resolving difficult coupling and dislodgment risks.

A one-way valve inverts flow direction to vent air during filling and admit air during emptying, maintaining the outer shape while preventing oxidation.

A tube skirt welding device uses internal heating and cooling to form a side weld on a flexible strip.

Ball milling roasted sesame seeds creates thixotropic tahini, preventing oil separation during storage.

A tube manufacturing method forms a parison in a mold to create an integrated blank with two end portions.

HDPE-based flexible tubes resist stress cracking and block water vapor while maintaining injection-moldability through optimized melt flow index.

Variable panel lengths and strategic extra dimensional length prevent deformation during expansion while maintaining structural integrity for compact storage.

An integrated food package merges a container and spreading device into one unit for convenient dispensing.

A flip-top tube cap uses a label film with a weakened region to form a tamper-evident seal that breaks upon first opening.

Telescoping arms in a tube squeezing device push remaining material toward the dispensing end, eliminating wastage and reducing manual effort.

Removable coupler cap exposes fitment opening to reduce cleaning time between confectionary types.

A flexible inverted container uses a sliding panel-cap nozzle to dispense liquid via gravity.

A transport container cover extends along a sleeve formed by the flexible compartment system to create a physical barrier.

A flexible container uses a structural support frame and gusset to maintain stand-up orientation while integrating a tear-open dispensing spout.

A tube head shoulder uses a curved attachment surface to extend skirt coverage and improve sealing integrity.

Internal heating and compression form the side weld while stabilizing layers protect the decorative film from thermal degradation.

Segmented reinforcing lines on flexible packages enhance panel flatness and graphic visibility while reducing buckling without adding weight.

A nozzle plug with embossments creates longitudinal openings that regulate fluid flow through a threshold pressure mechanism.

Composite HDPE, EVOH, and COC shoulder material minimizes flavor loss and antibacterial adsorption without extra inserts.

Multilayer composite films withstand user stress while maintaining thin profiles and barrier properties.

A tube container holder uses a groove portion to sandwich the sealing portion for secure suspension.

Bonding folded material layers creates an integrated dispensing tip that eliminates separate components and reduces manufacturing complexity.

A locking ring and ribbed plug seal a thin-walled dispensing container by entrapping the peripheral wall, preventing collapse and leakage during squeezing.

A tube extraction device uses a hinged upper plate and constrictor to dispense contents.

Segmented plugs with pressure-responsive bellows portions regulate fluid dosage and prevent clogging in cosmetic dispensing systems.

Breakable bridge recovers as a retaining connector to prevent accidental opening and eliminate material waste.

A dosing device uses a rotating wheel and ball piston to control cream volume.

Bilateral pressure plates empty aluminum tubes completely while maintaining labeling visibility and preventing air ingress.

A universal tube shoulder uses an internal opening collar to define the outlet diameter for standardized lids.

A multi-purpose cap seals tube spouts while providing a flat pressing surface for manual content control.

Overmolding merges a flat insert into the tube head shoulder, eliminating positioning errors and leakage risks.
