Cosmetic Dispensing Device with Nested Refill Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for cosmetic products require frequent removal and replacement of the spray head for refilling, leading to impractical use and aesthetic and stability issues during refilling.
Innovation Solution
A dispensing device comprising a mother bottle and a daughter bottle with a refill mechanism where the daughter bottle is received in a recess of the mother bottle, allowing simultaneous actuation of the dispensing member and refill mechanism with a single force, eliminating the need for a separate dispensing head on the mother bottle and ensuring stable and aesthetic coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the spray head is removed to refill the large bottle, then refilling is possible, but the device becomes impractical and aesthetically compromised
Solution Approach 1:
The device is segmented into two functional units: a large storage bottle and a small dispensing bottle with integrated spray head. This allows the spray head to remain permanently attached to the dispensing bottle while refilling occurs through a separate refill mechanism, eliminating the need to remove the spray head for refilling operations.
Solution Approach 2:
A refill mechanism acts as an intermediary between the large storage bottle and the small dispensing bottle. This intermediary system enables product transfer without requiring direct access to the spray head or removal of dispensing components, maintaining both functionality and aesthetics during refilling.
2Adaptability or versatility
If a separate dispensing head is added to the mother bottle, then dispensing capability is improved, but device complexity increases
Solution Approach 1:
The small dispensing bottle serves multiple functions: it acts as a storage container, a dispensing unit with integrated spray head, and a coupling interface for the refill mechanism. This multi-functionality eliminates the need for a separate dispensing head on the large bottle, maintaining versatility while minimizing structural complexity.
Solution Approach 2:
The small dispensing bottle with its integrated dispensing mechanism is nested within or coupled to the large storage bottle through the refill mechanism. This nesting arrangement allows the smaller functional unit to provide dispensing capability while the larger unit provides storage, avoiding the need for additional complex structures on the mother bottle.
3Stability of the object's composition
If the daughter bottle is fully received in the recess, then stability and aesthetics are improved, but access for refilling may be limited
Solution Approach 1:
The refill mechanism is pre-configured with coupling elements that engage automatically when the small dispensing bottle is placed in the recess. This preliminary arrangement of refill components allows the bottle to be fully received for stability while the pre-positioned mechanism remains accessible for initiating the refilling process.

AI summary
A dispensing device for dispensing a liquid or pasty product, in particular a cosmetic product, including a daughter bottle, a mother bottle and a refill mechanism. The daughter bottle is equipped with a dispensing member and a daughter portion of the refill mechanism. The mother bottle is equipped with a mother portion of the refill mechanism and defines a recess for removably receiving the daughter bottle. The daughter portion is configured to couple to the mother portion when the daughter bottle is received in the recess. The refill mechanism is then able to refill the daughter bottle with product from the mother bottle. The dispensing device transmits an actuation force of the dispensing member in order to actuate the refill mechanism. The force required for actuating the dispensing member is greater than or equal to the force required for actuating the refill mechanism.
