Notched applicator dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic testers, such as tubes of lipstick and mascara, lack hygiene guarantees as they are not single-dose and do not allow for precise application or touch-ups, posing hygiene risks in retail and educational settings.
Innovation Solution
A dispenser for single-dose touch-up, correction, and application applicators with a conical shape for precision, made from recyclable materials like polyethylene or polypropylene, featuring a pusher and peripheral body design for easy ejection and ergonomic handling, optionally with flocking for improved adhesion and product distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard cosmetic testers (tubes of lipstick, mascara) are used, then product availability is maintained, but hygiene guarantee is lost
Solution Approach 1:
The cosmetic product is divided into single-dose applicators that are individually packaged and dispensed one at a time. Each applicator is a separate unit containing a specific amount of product, eliminating the need for shared containers and ensuring hygiene while maintaining product availability.
Solution Approach 2:
The invention uses disposable single-dose applicators that are discarded after one use. This eliminates hygiene concerns associated with reusable containers while keeping each unit simple and cost-effective. The applicator includes a body, cap, and product reservoir designed for single-use disposal.
2Reliability
If simple spatulas or cotton swabs are used as testers, then hygiene is improved, but application precision is lost
Solution Approach 1:
The applicator is designed with different parts having specific qualities: the tip is shaped for precise application (conical or flat depending on product type), the body provides structural support, and the cap protects the product. This localized optimization of each part's properties enables both hygiene and precision.
Solution Approach 2:
The applicator is pre-filled with the exact amount of product needed for one application during manufacturing. The product is sealed within the applicator body before use, ensuring precise dosage and eliminating the need for manual product transfer or measurement by the user.
3Adaptability or versatility
If multiple applicators are stored together, then product variety is maintained, but cross-contamination risk increases
Solution Approach 1:
Multiple single-dose applicators are nested within each other inside a dispensing container. Each applicator is inserted into the previous one, creating a compact stack that protects each applicator from contamination while allowing easy access to individual units. The nested structure maintains product variety without increasing cross-contamination risk.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures perfect hygiene by using single-dose applicators, allowing precise application and touch-ups while promoting ecology and cost efficiency through recyclable materials, suitable for various cosmetic and pharmaceutical products.
Implementation Method 1
the projections being made flexible and elastic by lateral indentations
Implementation Method 2
the peripheral body which is free longitudinally there and back with respect to the upper body drives the pusher and the applicators in a longitudinal movement towards the upper end of the dispenser
