Vented Lid With Segmented Partition For Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vented lids for containers with volatile substances, such as air fresheners and insecticides, face issues with accidental leakage during transport and storage, leading to moisture marks on packaging and potential product rejection due to adhesive failures when exposed to volatile substances.
Innovation Solution
A lid design featuring a fixed perforated wall dividing the internal space into two cavities, with a removable partition that fits snugly within the lid's peripheral wall, creating a gap between the perforated area and the outer packaging, preventing moisture from reaching the packaging and featuring a gripping element for easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lid with perforations is used to allow volatile substances to reach the atmosphere, then the volatile substances can be released when the device is in use, but accidental tipping or leakage during transport and storage causes moisture to reach the adhesive packaging, leading to moisture marks and product rejection
Solution Approach 1:
The lid is segmented into two functional zones: a lower perforated wall for ventilation and an upper sealed area for packaging protection. This segmentation allows the lid to simultaneously provide venting functionality while preventing moisture from reaching the adhesive packaging during transport and storage.
Solution Approach 2:
The invention introduces a vertical dimension to the lid structure by creating a raised upper base that elevates the packaging material above the perforated area. This dimensional change creates a physical barrier that prevents moisture traveling downward from reaching the packaging, thus protecting it while maintaining ventilation below.
2Ease of manufacture
If adhesive stickers are used to seal the lid base, then the lid can be easily closed and sealed, but the adhesive is not resistant to volatile substances and moisture, causing it to fail during transport and storage
Solution Approach 1:
The invention extracts the adhesive sealing function from the area exposed to volatile substances and moisture. By positioning the adhesive on the upper sealed base away from the perforated lower section, the adhesive is protected from direct contact with harmful substances while still providing effective sealing.
Solution Approach 2:
The raised upper base structure acts as an intermediary barrier between the volatile substances in the lower cavity and the adhesive sealing the packaging. This intermediate structure prevents direct contact between the adhesive and harmful substances, protecting the adhesive's integrity while maintaining the sealing function.
3Device complexity
If the perforated area is positioned close to the outer packaging, then the lid structure is simplified, but any leakage directly contacts the packaging causing moisture marks
Solution Approach 1:
The lid is divided into distinct functional zones with the perforated lower wall separated from the upper sealed base. This segmentation creates a spatial buffer zone that prevents direct contact between leakage from the perforated area and the packaging material on the upper base.
Solution Approach 2:
The invention uses vertical elevation to separate the perforated area from the packaging. By raising the packaging-carrying upper base above the perforated lower wall, a vertical distance is created that prevents moisture from the perforated area from reaching the packaging during normal operation and transport.
