Container Lid Living Hinge Seal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container/lid combinations are prone to leakage and difficulties in securing the lid after repeated washing and drying, leading to a loss of airtight seal.
Innovation Solution
A lockable container with an airtight lid system and a locking mechanism, featuring a container body and lid connected by a living hinge or latches that provide a secure, leak-proof seal, and can be permanently or removably attached, ensuring the lid remains securely connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional container lid system is used, then the container can be easily assembled and disassembled, but the lid becomes prone to leakage and loses its airtight seal after repeated washing and drying cycles
Solution Approach 1:
The patent employs a living hinge that allows the lid to dynamically adjust and flex during washing and drying cycles, accommodating thermal expansion and contraction while maintaining the seal. The hinge provides controlled movement that prevents deformation of the sealing surfaces, ensuring the airtight seal is preserved after repeated wash cycles.
Solution Approach 2:
The patent integrates the latch mechanism and sealing elements into a unified lid assembly that works together as a single functional unit. The latch, seal, and living hinge are combined to create an integrated system that maintains reliability while remaining easy to operate, eliminating the need for separate securing components.
2Reliability
If the lid is made securely attached to prevent misplacement, then the lid remains connected after washing, but the container becomes more complex in structure
Solution Approach 1:
The living hinge provides a dynamic connection that allows the lid to move and flex while remaining attached to the container body. This elastic connection accommodates washing and drying cycles without requiring complex rigid attachment mechanisms, maintaining simplicity while ensuring the lid does not become misplaced.
Solution Approach 2:
The patent uses a flexible living hinge made from elastomeric material that connects the lid to the container body. This flexible connection is simple in structure yet effective in preventing lid misplacement while withstanding repeated washing cycles, avoiding the need for complex mechanical fasteners or adhesives.

AI summary
A container that includes a container body and a securely attached container lid. The container lid can form an airtight and/or liquidtight seal between the container lid and the container body when the container lid is in the fully closed position and locked position. The container lid is attached to the container body by a hinge. The container lid includes a seal member, cover window portion, and an outer rim portion having a plurality of lid latches. The latches are configured for movement between an unlatched position in which the container contents can be accessed and a latched position in which latch features engage fastening members to secure the container lid in the fully closed and locked position to the container body.
