Lid Collar with Breakable Band for Pressurized Container Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable containers fail to replicate the premium drinking experience of glass or high-end beverage consumption, and struggle with securely sealing pressurized contents like carbonated beverages, often leading to difficulties in opening and potential pressure issues.
Innovation Solution
A lidded container design featuring a lid collar with a bottom ring, container mount, and lid mount, which includes non-circular facets to prevent rotational movement and a breakable band for visual tampering indication, allowing for secure closure and gradual pressure release during opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a disposable container uses a simple lid design, then manufacturing cost is reduced, but sealing reliability and pressure containment deteriorate
Solution Approach 1:
The lid is divided into multiple functional components: a collar that interfaces with the container, a breakable band for tamper indication, and a lid body with engagement features. This segmentation allows each component to be optimized for its specific function while maintaining overall reliability at reasonable manufacturing cost
Solution Approach 2:
The breakable band is pre-installed in a broken state or designed to break upon opening, providing immediate tamper indication before the consumer even opens the container. The collar is pre-formed with facets that will naturally engage with the container mouth, ensuring proper alignment and sealing before use
2Reliability
If a container uses a secure closure mechanism, then sealing reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The breakable band is designed to break automatically or with minimal force during the opening process, providing a clear visual indication that the container has been opened. This preliminary action of breaking the band occurs as part of the normal opening sequence, requiring no additional effort from the user
Solution Approach 2:
The collar features non-circular facets that provide asymmetric engagement with the container mouth. This asymmetric design prevents rotational movement and ensures proper alignment, making the opening process more intuitive and easier to operate while maintaining secure sealing
3Object-affected harmful factors
If a container is designed to prevent accidental opening, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The non-circular facets on the collar create an asymmetric engagement mechanism that prevents rotational movement. This asymmetric design makes accidental opening difficult while still allowing intentional opening when the user applies the correct force in the correct direction
Solution Approach 2:
The breakable band serves as a preliminary safety mechanism that must be broken before the container can be opened. This creates a deliberate action sequence that prevents accidental opening while still allowing easy opening when the user intentionally breaks the band
4Reliability
If a container uses non-circular facets to prevent rotation, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The non-circular facets are integrated directly into the collar structure, which is already a necessary component for securing the lid. This asymmetric feature adds rotational prevention functionality without requiring separate components, thereby maintaining sealing reliability while minimizing additional structural complexity
Solution Approach 2:
The rotational prevention facets are merged with the collar structure, combining multiple functions (sealing, securing, and preventing rotation) into a single integrated component. This reduces the overall number of parts and simplifies the manufacturing process while maintaining reliability

AI summary
A package includes a container formed to include a product-storage region and a mouth arranged to open into the product-storage region and a closure configured to mate with the container and establish a closed arrangement of the package and to be separated from the package at the option of a user to establish an opened arrangement.
