Rotatable Lid Airtight Compact for Volatile Product Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable vessels for volatile and aggressive products are fragile, prone to damage, and have loose parts, making them difficult to manage and resulting in a poor seal due to indirect compression of gaskets, which affects the containment and longevity of the product.
Innovation Solution
An airtight compact design featuring a rotatable lid pivotably attached to a base assembly, which directly compresses a liner to the rim of a translucent pot, providing a secure and visible containment solution for volatile products, with components made from materials like Surlyn, glass, ABS, and metal for structural integrity and barrier properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a loose lid and protective shell design is used, then the vessel is less fragile and more protective, but it becomes difficult to manage both the loose lid and protective shell while applying product
Solution Approach 1:
The lid is pivotally coupled to the base assembly, merging the lid and base into a single integrated unit that remains connected during use. This eliminates the need to manage separate loose lids and protective shells, while still providing protection when closed.
Solution Approach 2:
The lid transitions from a static loose component to a dynamic pivotally connected component that can rotate between open and closed positions. This dynamic connection allows the lid to remain attached during application while still providing full protection when closed.
2Strength
If a gasket is compressed indirectly by tightening a lid onto a loose plastic lid, then the assembly is more protective, but sufficient compression of the gasket is difficult to achieve resulting in a poor seal
Solution Approach 1:
The intermediate loose plastic lid is removed from the system. The rotatable lid now directly engages with the base assembly and directly compresses the gasket against the pot rim, eliminating the transmission of compression force through multiple components.
Solution Approach 2:
The gasket serves as the direct intermediary between the rotatable lid and the pot rim. By removing the loose plastic lid, the gasket becomes the primary sealing element that directly receives compression force from the lid assembly.
3Reliability
If existing portable vessels are made with glass or metal, then they provide effective barrier for containing volatile product, but they are fragile or brittle in nature and susceptible to damage
Solution Approach 1:
The vessel uses a composite structure combining a translucent plastic pot (impact-resistant) with a gasket sealing system. This replaces the traditional glass or metal construction while maintaining the volatile product containment capability through the gasket-sealed interface.
Solution Approach 2:
A flexible gasket material is introduced as the primary sealing component. This flexible element compensates for the lower structural strength of translucent plastic while maintaining an effective seal, unlike rigid glass or metal systems.
4Strength
If the product is contained in a plastic pot, then the vessel is less fragile, but it may not be suitable for containing volatile product to be applied to the body
Solution Approach 1:
The gasket acts as an intermediary sealing layer between the plastic pot and the rotatable lid. This gasket provides the necessary barrier properties for volatile product containment, compensating for the lower inherent barrier properties of plastic compared to glass or metal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the durability and ease of use of portable vessels by providing a secure seal and visibility of the product, reducing the risk of damage and improving the containment of volatile products, while allowing for easy replacement of pots and improved user experience.
Implementation Method 1
directly squish a liner fixed to a bottom surface of the rotatable lid assembly to a rim of the pot

AI summary
An airtight compact that contains a volatile product until a time of use. The airtight compact includes a translucent and fragile pot partially encased by a base assembly, which has a rotatable lid assembly pivotably coupled to the base assembly. The rotatable lid assembly comprising a liner over-molded to an inner lid that directly seals to a rim of the fragile pot partially encased by the base. The fragile pot may be formed of a translucent glass, which is protected by the base and the rotatable lid assemblies.
