Wet wipe sealing cap structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet wipe sealing technologies fail to achieve airtight sealing due to flexible materials and irregular bag surfaces, leading to water vapor escape and contamination, and are inconvenient to assemble and use.
Innovation Solution
A wet wipe sealing cap structure comprising a base ring, claw plate, and cover device with sloping ribs and a flexible member, which securely engages to prevent water vapor escape and facilitates easy assembly by using a cap that frictionally engages with the base ring's outer and inner locating units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a re-sealable sealing tag is used to seal the opening, then the sealing function is provided, but the airtight sealing effect cannot be achieved due to flexible materials and surface irregularities
Solution Approach 1:
The sealing structure is divided into multiple components: a rigid base ring with locating units, a claw plate with engagement units, and a cover device with a cap. This segmentation allows each component to perform its specific function - the base ring provides structural support, the claw plate provides sealing contact, and the cap provides closure - while collectively achieving reliable airtight sealing that overcomes the limitations of single-piece flexible sealing tags.
2Ease of operation
If the opening of the bag is made large for finger access, then ease of use is improved, but water vapor escape is increased
Solution Approach 1:
The sealing structure uses a flexible member connected between the cap and collar that can deform to conform to the container opening while maintaining the seal. This flexible element allows the sealing mechanism to adapt to various opening sizes and shapes, providing effective sealing even when the opening is large enough for finger access, thereby preventing water vapor escape while maintaining ease of use.
3Duration of action of stationary object
If the re-sealable sealing tag is used multiple times, then reuse is achieved, but stickiness weakens due to contamination
Solution Approach 1:
The sealing function is extracted from the adhesive sealing tag and transferred to the mechanical engagement system consisting of the base ring, claw plate, and cap with their respective locating and engagement units. This extraction removes the dependency on adhesive stickiness, allowing the sealing mechanism to be reused multiple times without degradation, as the mechanical interlocking components can be opened and closed repeatedly without contamination affecting their sealing capability.
4Object-affected harmful factors
If a buckle cap member is used to cover the opening, then dustproof function is provided, but airtight sealing is insufficient
Solution Approach 1:
The sealing structure incorporates curved and rounded surfaces in the design of the base ring, claw plate, and cap components. The circular cross-section of the base ring and the curved engagement surfaces allow for complete contact between sealing surfaces, eliminating gaps that would permit air passage. This curvature-based design enhances the sealing effectiveness beyond simple dust protection, achieving reliable airtight sealing.
