Package Recycling TRIZ Cases
- Disposable Permeable Filter for Mess-Free Single Cup Brewing
A disposable permeable filter basket with a retaining collar enables quick beverage brewing without mess.
- Reusable Envelope Closure Flap with Segmented Adhesive Layers
Segmented adhesive layers and aligned weakening lines allow sequential opening of reusable envelopes without complex manufacturing steps.
- Liquid Level Sensing via Pressure Measurement Channel
A dispensing conduit uses a fixed-height pressure measurement channel to determine liquid levels without internal sensors.
- Packing Box Folding System with Movable Suction Device
Automated system uses movable suction and pressing devices to fold empty boxes, eliminating time-consuming manual labor.
- Double-Layer PET Dispensing Container with Air Intake
Flexible inner container deflates as content decreases while outer shell admits external air through an intake hole.
- Reusable Pressurized Gas Device with Large-Diameter Thread
A reusable reservoir uses a large-diameter threaded ring to secure a detachable refill pouch for propelling active ingredients via pressurized gas.
- Multilayered Container With Pleated Inner Liner for Airless Dispensing
A multilayered container uses a pleated inner liner that shrinks vertically to match content volume.
- Pallet Base Frame With U-Shaped Central Feet For Torsion Resistance
U-shaped central feet with edge webs reinforce pallet base frames, preventing torsion breakdown during asymmetrical impacts.
- Reusable Glove Dispenser with Disposable Inner Pouches
Disposable inner pouches prevent moisture absorption and contamination while reusable outer boxes reduce packaging waste.
- High-Density Polyethylene Stretched Film Thermal Shrinkage Control
Stretching high-density polyethylene at 125°C to 130°C reduces thermal shrinkage below 3% to prevent wrinkles.
- PEVA Storage Bag Double-Locking Seal
A PEVA storage bag uses a double-locking closure mechanism to create an airtight seal.
- Reusable Two-Way Mailing Bag Self-Folding Design
A reusable mailing bag folds into an internal pouch to create a compact shipping unit.
- Cellulose Fiber Dispersion in Polyolefin Resin Composite
Batch kneading polypropylene resin with Mz/Mw ratio 4 disperses cellulose fibers, resolving uniform dispersion and homogeneous composition trade-offs.
