Powder Dispenser Sealing Component Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder dispensers for feeding bottles lack reliable sealing, leading to potential contamination when the bottle is tilted, and are difficult to handle, clean, and require multiple components.
Innovation Solution
A dispenser design featuring a receptacle and adapter with a sealing component comprising upper and lower annular parts connected by arms, ensuring secure sealing between components and the container, and allowing easy mounting, dismounting, and cleaning, with a reduced number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sealing is achieved only by gripping the neck of the feeding bottle in a channel arranged at the level of the wall of the adapter, then the device complexity is reduced, but the reliability of sealing deteriorates
Solution Approach 1:
The sealing component is divided into an upper annular part and a lower annular part, with the upper part providing sealing between the adapter and container, and the lower part providing sealing between the powder container and adapter. This segmentation allows each sealing surface to be optimized independently, improving overall sealing reliability while maintaining relatively simple device complexity.
2Reliability
If the powder container is sufficiently screwed to ensure sealing between the powder container and connector, then the sealing reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The sealing component is designed to be supported by the adapter itself, rather than requiring additional external sealing elements. The upper and lower annular parts with connecting arms form a self-contained sealing system that automatically engages when the powder container is mounted, ensuring reliable sealing without requiring excessive tightening while maintaining ease of operation.
3Reliability
If multiple components are used to ensure reliable sealing, then the sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The sealing component merges the upper and lower sealing functions into a single integrated structure with connecting arms, rather than using separate sealing elements for each interface. This merging reduces the total number of components while maintaining reliable sealing at both the adapter-container interface and the powder container-adapter interface.

AI summary
A dispenser for a powder in a container, containing a receptacle including an end wall provided with at least one orifice, an adapter including a tubular body provided with a transverse partition provided with at least one orifice, the receptacle being rotatable on the adapter between a closed position of the dispenser, in which the orifice in the receptacle and the orifice in the adapter are not aligned with one another, and an open position of the dispenser, in which the orifice in the receptacle and the orifice in the adapter are positioned in line with one another, and a sealing component comprising an upper annular part and a lower annular part arranged so as to ensure sealing between the container and the adapter and between the adapter and the container, respectively, when the adapter is mounted on the container.
