Cans/Barrels/Drums TRIZ Cases

See how a bracket engaging less than 180 degrees of a canister reduces weight, collision risk,

An integrated suction lance and separately sealed closure enable residue-free canister emptying while preventing operator contact with fluid.

A variable-diameter punch thins the can neck while preserving body strength, cutting material use and supporting secure double seaming.

High-speed ironing softens high-Tg polyester can coatings, preventing forming defects and heat-treatment peeling while preserving flavor resistance.

A thinner dome, wider lower ring, and spaced concave deformations cut can weight while preserving pressure resistance, axial strength, and stackability.

A 59 mm can body and optimized domed base cut metal use while keeping 200 end compatibility, 6.2 bar pressure resistance, and 550 N top load.

Optimized dome curvature ratios let a thinner two-piece metal can resist internal pressure and impact buckling without sacrificing can volume.

A two-step bottom coating process keeps the reformed grounding portion covered, improving seamless can conveyability and compressive strength.

Two-stage bottom coating keeps the seamless can grounding portion covered after reformation, reducing friction while preserving conveyability.

A reshaped dome and lower ring with concave deformations cut can weight while maintaining internal pressure and axial resistance.

A dual-curvature can bottom with annular support resists water-hammer inversion during drops while preserving pressure resistance in thinner cans.

A raised can bottom with a controlled area ratio improves pressure resistance while allowing thinner metal and lower material usage.

A 58-60 mm body and 44-48 mm stand cut metal use while preserving 6.2 bar resistance and standard end-plate compatibility.

Using one heat-treatable aluminum alloy for both can body and end simplifies recycling while maintaining strength with thinner sheets.

A polished diamond-film ironing die enables dry draw-ironing that preserves metallic luster, smoothness, and stable brilliance.

A groove-separated full-open lid and knockout pad improve pouring comfort while keeping the can seam stable and leak resistant.

A recessed can-bottom dome formed without roll interference boosts pressure resistance while avoiding surface blackening.

Reverse extrusion die projections form tactile outer relief on can packaging while keeping the inner surface smooth for efficient filling and emptying.

A two-part wall-ironing approach thins pre-coated can walls, forms tapers and steps, and avoids coating damage and edge burrs.

Wall ironing on pre-coated metal reduces can wall thickness while forming tapers or steps without damaging polymer coatings.

A polished diamond-film ironing die creates a smooth uncoated can surface with stable metallic luster and reduced directional brilliance variation.

Progressive clamp bead tooling selectively thins a can bottom dome to cut material use while limiting wrinkling, buckling, and forming force.

A vertically and rotationally adjustable funnel stabilizes waste oil capture and reduces splashing without moving the drain container.

A concave center panel replaces groove-based reinforcement to handle internal pressure, reduce debris trapping, and ease can opening.

A polished diamond-film ironing die enables dry draw-ironing of aluminum cans with uniform metallic brilliance, lower cost, and no washing step.

A locally thickened can bottom improves pressure resistance in thinner seamless cans while avoiding blacking, agglutination, and extra cleaning.

An inward burr and upstanding wall let the grommet seal and charge propellant while keeping uncoated metal away from the beverage.

A stepped wall-ironing punch forms nestable metal cans with tapers while reducing wall thickness and protecting pre-applied polymer coatings.

An annular wall-ironing die thins and lengthens pre-coated can walls without crossing the open end, avoiding coating damage and burr detachment.

Wall ironing thins pre-coated can walls without damaging coatings, enabling tapered or stepped nestable containers with less trimming.

Sequential bead and countersink forming keeps the can end clamped to limit stretching, thinning, warping, and fractures.

Annular ridge and countersink geometry helps thinner can ends withstand buckle and reverse buckle pressure with less material.

An expanding collet supports the can from inside during neck curling, preserving sharp shoulder geometry in steel and aluminum cans.

A rotating flap and rivet let an opened can be reclosed repeatedly, helping keep beverages clean during transport and storage.

Movable cores vary mold cavity volume during forming to create density layers and projections that improve rigidity, insulation, and ejection.

Embossed 2D sidewall protrusions plus a paperboard sleeve let steel cans use less metal while maintaining axial strength and dent resistance.

A wide, low-profile base keeps a filled gas can bottom-heavy, reducing tip-over risk while preserving fluid transfer through the spout.

A graded-thickness can bottom boosts pressure resistance and restrains buckling while avoiding blacking, agglutination, and cleaning steps.
