Bottles TRIZ Cases

PET containers use cyclic olefin copolymer or polymethylpentene additives to achieve high opacity.

A pressurized container housing uses distinct retaining means to secure a stopper against internal pressure forces.

Radially oriented waves in the push-up portion resist deformation under pressure, ensuring structural integrity during pasteurization.

A thermoplastic alloy pump cylinder combines polypropylene homopolymer with high-density polyethylene to enhance mechanical strength.

Reinforcing ribs extend into finger-recesses of the integrated hand-grip to prevent slippage in large-volume plastic containers.

Offsetting a variable-width annular rib from grip panels prevents structural opening during vacuum pressure, maintaining roundness.

Longitudinal recesses in a blow-molded support ring resolve stability issues while enabling efficient water drainage.

A multi-layer bottle uses a gas-filled void to let the inner layer flex independently.

A synthetic resin preform uses co-injection molding to deposit a colored layer on the base material, creating a distinct visual gradient.

Segmented flexible panels and posts in a plastic container sidewall ensure uniform deflection under vacuum uptake, resolving asymmetric contraction issues.

Sloped foot flanks and radial stiffeners enhance blowability while cheeks maintain rigidity against bottom reversal.

Varying groove depth reduces mold undercut to prevent surface scratches while maintaining sufficient pressure absorption capacity.

A single-layer PET bottle uses titanium dioxide and metallic aluminium fillers to achieve virtually total light shielding while maintaining a white surface.

Radial ramps in a flexible bottom panel absorb vacuum pressure, preventing sidewall collapse without adding weight or ribs.

Two-stage stretch blow molding copolyester containers with sharp edges under 0.5 mm radius, resolving material tearing and strain hardening.

Multilayer crystallizable shrink film uses amorphous copolyester core and recycled PET to produce controlled dimensional reduction.

Integrated sidewall handles on a hollow plastic container allow easy dispensing while a sloped shoulder and extended neck provide obstacle clearance.

Molding container sides as lens surfaces eliminates separate label costs while maintaining high image quality and brightness.

Sliding or rotating the nozzle relative to the shroud modifies fluid flow paths, resolving the trade-off between dispensing versatility and device complexity.
