Frangible Sizing Seal for Receptacle Liner Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liners for receptacles lack features to securely grip the rim, leading to instability and potential falling during use.
Innovation Solution
A liner design featuring a frangible sizing seal structure along the top edge margin, allowing the liner opening to be selectively enlarged to fit securely over the receptacle rim, with adjustable sizing seals that break progressively to accommodate different receptacle sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the liner opening size is fixed during manufacturing, then the manufacturing process is simple, but the liner cannot accommodate different receptacle sizes
Solution Approach 1:
The top edge margin is segmented into multiple sections by transverse spacing lines, allowing the opening to be divided into adjustable segments. Users can separate the panels along different spacing lines to achieve different opening sizes, enabling adaptation to various receptacle dimensions without complicating the overall liner structure.
Solution Approach 2:
The liner opening transitions from a fixed static structure to a dynamic adjustable structure. The panels can be selectively separated along transverse spacing lines to change the opening size, allowing the same liner to adapt to different receptacle sizes while maintaining structural integrity through the connected side margins.
2Adaptability or versatility
If the liner opening is made large to fit larger receptacles, then versatility is improved, but the liner cannot securely grip smaller receptacle rims
Solution Approach 1:
The top edge margin is divided into multiple adjustable segments by transverse spacing lines. Users can separate the panels to different extents depending on the receptacle size, allowing the opening to be optimized for each specific application. This ensures secure grip on smaller receptacles while maintaining versatility for larger ones.
Solution Approach 2:
The opening size parameter can be dynamically changed by separating the front and rear panels along different transverse spacing lines. This allows optimization of the opening diameter to match the receptacle rim size, ensuring reliable grip while accommodating various receptacle dimensions.
3Reliability
If the liner opening is made small to secure grip on smaller receptacles, then grip stability is improved, but the liner cannot fit larger receptacles
Solution Approach 1:
The top edge margin incorporates multiple transverse spacing lines that enable the opening to be segmented into different configurations. Users can separate the panels along appropriate spacing lines to achieve the optimal opening size for each receptacle, ensuring both secure grip and adaptability across different sizes.
Solution Approach 2:
The liner opening is designed as a dynamic structure that can be adjusted from a smaller initial state to larger configurations. By selectively separating panels along transverse spacing lines, users can adapt the opening size to match different receptacle dimensions while maintaining secure grip through proper sizing.
4Adaptability or versatility
If multiple pre-configured opening sizes are provided, then adaptability to different receptacles is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
Instead of providing multiple pre-configured openings, the liner uses a single top edge margin with multiple transverse spacing lines. Users can manually segment the opening to the required size by separating panels along the appropriate spacing line, achieving multi-size adaptability without the complexity of multiple pre-formed structures.
Solution Approach 2:
The liner opening transitions from a static single-size design to a dynamic adjustable design. A single opening structure can be transformed into different effective sizes by separating panels along different transverse spacing lines, providing versatility without the complexity of multiple pre-configured openings.

AI summary
A liner for lining a receptacle has a front panel and a rear panel that define an interior and a top opening in fluid communication with the interior. A frangible sizing seal structure joins together the front and rear panels along the top of the liner adjacent a side of the liner. The sizing seal structure limits a size of the liner opening and is configured to be selectively broken to separate the front and rear panels to enlarge the size of the liner opening so that the top edge margin fits over a rim of the receptacle. In a method of making the liner, the front and rear panels are sealed together to form the frangible sizing seal structure.
