Removable Lids/Covers TRIZ Cases
- Molded Pulp Lid Undercut Formation via Suction Holes
Suction holes in molds form convex undercuts on molded pulp lids, preventing shape damage during detachment from drying equipment.
- Foldable Container Hinged Walls and Latch Assemblies
Segmented hinged walls and spring-loaded latches resolve the contradiction between structural rigidity in use and compact collapsibility for storage.
- Container Latching System With Slide Lock Seals
Segmented slide lock latches track along extended lid lip sections to create an air-tight seal while reducing mechanical complexity.
- Thermoformed Package Tray with Integrated Breaking Rim
Vacuum forming creates an integral tray and cover rim with a localized breaking portion, eliminating separate assembly steps and reducing material waste.
- Child-Resistant Lid with Segmented Grip for Senior Access
Segmenting the closure into an inner child-resistant lock and an outer ergonomic grip resolves the reliability versus ease-of-operation trade-off.
- Interlocking Case Assembly for Electronic Devices
Nested case assembly with interlocking features increases creepage distance and bonding strength to prevent electric leakage and structural fracture.
- Ice Cream Container Lid Vents for Pressure Relief
Vented lids on rigid containers accommodate gas expansion at high altitudes, preventing structural deformation and maintaining seal integrity.
- Tearable Lid Container with Orientation Indicator
A container lid connects via a tear line that separates from an intact base, revealing the connecting portion's orientation.
- Beverage Cup Cover Anti-Overflow Groove and Sealing Design
A beverage cup cover uses an integrated upper sealing cover with partition bars to separate air outlets, preventing spillage during transport.
