Package Recycling TRIZ Cases

Rotary ultrasonic welding forms rounded edge seals on plastic corrugated blanks, resolving sharp edge safety issues and improving stack stability.

An embossed paper envelope structure delivers effective impact protection while reducing weight and cost compared to plastic alternatives.

A portable medication dispenser uses a microprocessor controller to sequentially deliver dosage packages from a housing compartment.

A multilayer film structure uses an adhesive resin layer to bond a polyolefin layer with an ethylene-vinyl alcohol copolymer composition.

Modular compartments in a reusable plastic pallet accommodate variable pot sizes, resolving the trade-off between adaptability and handling complexity.

Copolymerized polyester resin stabilizes heat-shrinkable film dimensions after aging by controlling neopentyl glycol and diethylene glycol mole fractions.

Resiliently-depressible tabs on a plastic sleeve unlatch latches from a blister card, balancing child resistance with senior accessibility.

Integrated hinge mechanism allows collapsible containers to maintain stable open configurations, preventing structural creasing during storage and filling.

Segmented interconnecting pieces form reusable shipping containers via a locking mechanism, eliminating single-use waste and overpackaging.

A concentrated product storage cartridge uses a sliding external body to release contents from a fixed internal plunger.

Vacuum pressure fixes a thermoplastic liner against drum walls, preventing creases and tears that cause leakage while allowing reuse of standard containers.

A refillable aerosol cartridge system dispenses viscous materials through a simple valve mechanism without external pumps.

Segmenting the clamp body from the loop via a screw mechanism enables repeated tightening and loosening without cutting, reducing waste.

A polymeric aerosol dispenser with a pressure relief valve prevents overpressurization during microwave heating, replacing slow conventional ovens.

Integrated latch mechanisms engage keeper formations to stabilize cover halves, eliminating manual alignment during nesting operations.

A packaging box uses segmented adhesive parts to bond an inner film to an outer paper shell while enabling easy separation for recycling.

A reusable food receptacle uses a frangible tab and living hinge to secure the lid while hiding sharp edges.

A reusable cylindrical proppant pod uses a frustoconical bottom and vent assembly to facilitate rapid discharge of granular material.

A collapsible shipping container made from a single piece of woven polypropylene mesh with integrated creases and rigid corners.

Segmented housing and insert assemblies allow complete disassembly, reducing plastic waste by enabling component reuse, recycling, or composting.

Incorporating butanediol and epsilon-caprolactone into polyester resin reduces secondary shrinkage and prevents creases during hot air tunnel processing.
