Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging bottles, such as press-type and pump-type bottles, face issues with complex structures, high manufacturing costs, instability due to lack of airtightness, and a tendency to fall apart during use.
Innovation Solution
A self-priming-pump-equipped packaging bottle design featuring a tubular bottle body, piston, upper seal assembly, and lower seal assembly, with an umbrella-shaped member, hollow material-feeding column, and elastic sealing gasket, which forms closed material-feeding and storing chambers, allowing for automatic material dispatch and stable feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a press-type packaging bottle is used, then the structure is simple, but the manufacturing cost is high and the structure is complicated
Solution Approach 1:
The packaging bottle is divided into distinct functional modules: a bottle body, a piston, an upper seal assembly, and a lower seal assembly. Each module can be manufactured separately and then assembled, which simplifies the manufacturing process and reduces costs while maintaining structural simplicity.
Solution Approach 2:
The upper seal assembly and lower seal assembly are integrated into the bottle body structure, combining sealing functions with the container structure. This merging reduces the number of separate components and simplifies both the structure and manufacturing process.
2Ease of manufacture
If a pump-type packaging bottle is used, then the manufacturing cost is reduced, but the airtightness between piston and bottle body is insufficient, causing unstable material feeding
Solution Approach 1:
A sealing ring is introduced as an intermediary element between the piston and the bottle body. This sealing ring ensures airtightness by filling the gap between the piston and bottle body, preventing leakage while allowing the piston to move freely for stable material feeding.
Solution Approach 2:
The sealing ring is a flexible thin film that can deform to accommodate slight variations in piston position and bottle body geometry. This flexibility ensures reliable sealing without requiring precise manufacturing tolerances, thereby maintaining airtightness while keeping manufacturing costs low.
3Productivity
If a negative-pressure packaging bottle is used, then the material feeding is improved, but the bottle falls apart during use due to insufficient firm combination between pump and bottle body
Solution Approach 1:
The piston is designed with a curved surface that matches the curvature of the bottle body's inner wall. This curved interface, combined with the sealing ring, creates a firm and stable connection between the piston and bottle body, preventing the bottle from falling apart during use while maintaining smooth material feeding.
Solution Approach 2:
The sealing ring acts as an intermediary that bonds the piston to the bottle body structure. This intermediary element distributes mechanical stresses uniformly across the sealing interface, enhancing structural stability and preventing disassembly during use while enabling reliable material feeding.

Function Achieved in This Case
The design provides a structurally simple, cost-effective, and reliable packaging solution with stable material feeding and aesthetic appeal, preventing the bottle from falling apart and ensuring consistent performance.
Implementation Method 1
the elastic sealing gasket naturally lies on the through hole of the seal seat, so that the material-storing chamber is isolated from the material-feeding chamber
Implementation Method 2
a lower end of the umbrella-shaped member being in interference fit with the seal seat
Implementation Method 3
the piston being installed in a lower part of the tubular bottle body... the lower seal assembly, the piston, and the tubular bottle body jointly forming a closed material-storing chamber

AI summary
A self-priming-pump-equipped packaging bottle includes a tubular bottle body containing therein an upper seal assembly, a lower seal assembly, and piston from top to bottom. The upper and lower seal assemblies and the tubular bottle body form a closed material-feeding chamber. The lower seal assembly, the piston, and the tubular bottle body form a closed material-storing chamber. The lower seal assembly primarily has a seal seat with a through hole and an elastic sealing gasket covering the through hole from above. The upper seal assembly has an umbrella-shaped member, a hollow material-feeding column, a support post, and an end sealing cap. The end sealing cap is fixed in the umbrella-shaped member through the support post. The hollow material-feeding column's bottom surface, the support post, and the end sealing cap form a material outlet. The umbrella-shaped member lower end is in interference fit with the seal seat.
