Bottles TRIZ Cases

Stretching a preform against a mold surface to sever the dome portion increases mold cavity capacity while reducing container weight.

A liquid container lid uses a pivoting seal plate to close the pouring spout.

Radial straps and recessed ribs place the PET container base in hydraulic charge-up, resisting deformation from top loading and vacuum pressure.

An integral pour spout retracts into an exterior recess to prevent spillage during liquid dispensing.

A rotating pressurizing member in the mold creates a deep handle engaging part, preventing detachment when filled with high-temperature liquids.

A thermoplastic container features a thickened curved annular region created by selective infrared heating of preforms.

An incurvate bridge creates a radial fluid channel that vents air and guides liquid flow, eliminating glugging during pouring.

A multi-use bottle merges a liquid container with a removable smoking assembly for seamless function switching.

A one-piece plastic container base uses radially spaced feet and straps to distribute internal pressure.

EVOH resin composition uses iron compound to suppress oxidation, resolving brittleness and coloration during melt processing.

Applying a hydrophobic layer to the inner glass bottle neck prevents gushing by inhibiting nanobubble formation from organic compounds.

An isolated organic crease on a geometric bottle conveys natural visual impressions without explicit representation.

Optimized petaloid base feet geometry increases breakage resistance and stability under extreme carbonated beverage pressures.

A cut neck plastic container uses a radially tapered wall and internal step to form a precise sealing interface with the closure cone.

A plunger with unevenness forming members presses a glass gob to create convex inner shapes during one-press molding.

Raised mid-sections on support columns pull toward each other during cooling, maintaining container integrity while reducing material usage below fifteen grams.

Internal embossments in bottle necks impart swirling action to liquid, releasing gas and forming a head in beverages like beer.

Circumferential reinforcing ribs with specific arcuate and straight line patterns enhance side-load resistance in plastic container grip portions.

An asymmetric flexible diaphragm in the container base buckles under pressure changes, preventing standing ring deformities caused by deep inset molding.

Segmented adhesive and perforated zones allow the film to detach from the container body when the lid rotates, eliminating manual removal steps.

A plastic bottle body uses elastic deformation to meter out precise liquid volumes.

An annular recess weakens resin flow to thin the outer sidewall, allowing the movable wall to pivot upward and absorb decompression forces.

A two-part bottom pad uses a rigid inner member and flexible outer elastomer to create a fluid-tight seal with the container body.

Segmented PET panels isolate thermal processing from labeling zones, maintaining clarity and flatness under hot fill pressure.

A threaded metal container neck features a bead portion to improve transverse rigidity at the mouth base.

Movable pressure panel in plastic container base adjusts position to manage internal volume changes during thermal cycles.

A plastic container dome uses a concave recess with a U-shaped groove and vertical reinforcing element to enhance structural stability.

A plastic bottle uses alternating depressible and depression-resistant wall portions to enable easy volume reduction.
