Refillable Cosmetic Dispenser Flexible Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refillable devices for cosmetics and care products often require large refill openings and necessitate removing the donor container's nozzle for refilling, limiting compatibility with various nozzle sizes and shapes, and requiring two-handed operations.
Innovation Solution
A refillable device with a flexible interface arrangement and attachment element that allows filling from donor containers with different nozzle sizes and shapes without removing the nozzle, using a one-handed, one-finger technique, and featuring a fill opening positioned slightly spaced apart from the nozzle, enabling efficient refilling with various nozzle configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large refill opening is used in existing refillable devices, then refilling is facilitated, but the device cannot maintain a compact size and aesthetic appearance
Solution Approach 1:
The interface arrangement is nested within the compact device body, allowing a functional interface compatible with various nozzle sizes to be integrated into a small form factor device without requiring a large external opening
Solution Approach 2:
The interface arrangement acts as an intermediary component between the donor container nozzle and the device interior, enabling product transfer through a controlled interface that accommodates different nozzle sizes while maintaining device compactness
2Ease of operation
If the donor container's nozzle is removed for refilling, then filling can be performed, but compatibility with various nozzle sizes and shapes is limited
Solution Approach 1:
The interface arrangement is designed with universal compatibility to accommodate multiple nozzle sizes and shapes from different donor containers, allowing the same device interface to work with various perfume bottle nozzles without modification
Solution Approach 2:
The interface arrangement serves as a mediator that adapts between the donor container nozzle and the device filling opening, enabling compatibility with various nozzle configurations while maintaining a consistent device interface
3Productivity
If traditional refilling methods are used, then product can be filled, but two-handed operations are required reducing convenience
Solution Approach 1:
The device enables one-handed self-service refilling by integrating the interface arrangement that allows the user to hold and operate the device with one hand while receiving product from the donor container, eliminating the need for two-handed coordination

AI summary
A product dispenser refillable from a donor container via a spray nozzle comprising a hollow body for receiving and storing said product, a dispensing mechanism for dispensing said product, an open aperture through which product is filled into said body, capping means to cap the open aperture after filling the container to prevent leakage of product from said opening, characterized in that the dispenser comprises a filling interface arrangement integrally coupled to said open aperture that guides the spray from the spray nozzle of the donor container directly into the open aperture of the dispenser.
