Disposable Frozen Cosmetic Applicator for Chilling Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic packaging for frozen products is inefficient due to large, cumbersome blocks that require multiple applications, leading to product degradation from freeze-thaw cycles and messy handling issues, while providing limited chilling effects.
Innovation Solution
A disposable unit dose packaging system comprising a reservoir and an applicator with a contoured, textured applicator head that houses and applies a single dose of frozen cosmetic or personal care product, allowing for effective skin contact and minimizing product wastage and degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large frozen blocks are used for multiple applications, then the product can be reused, but the product degrades due to freeze-thaw cycles and creates messy handling issues
Solution Approach 1:
The invention divides the frozen cosmetic product into multiple small unit-dose capsules, each containing a separate portion. This segmentation prevents freeze-thaw degradation because each capsule is individually portioned and can be used separately without exposing the entire product to repeated temperature cycles. The segmented approach maintains product reliability while enabling multiple applications through multiple capsules.
Solution Approach 2:
The invention employs disposable single-use capsules that are discarded after one application. This eliminates the freeze-thaw problem entirely by designing the product for single-use only, preventing any refreezing of melted product. The disposable nature ensures product integrity while providing sufficient quantity through multiple individual units.
2Temperature
If large frozen blocks are used, then the product can be stored in freezer, but the chilling effect is limited and product melts excessively during application
Solution Approach 1:
The invention uses small unit-dose capsules that contain only the necessary amount of product for a single application. This partial action approach ensures that the entire capsule can be applied to the skin before significant melting occurs, maximizing the chilling effect while minimizing product loss. The small size allows complete utilization of the frozen product.
3Ease of operation
If applicator head is used for spreading product, then the product can be applied evenly, but the thermal mass is too small to provide significant cooling
Solution Approach 1:
The invention merges the applicator function with the product delivery system by designing capsules with built-in applicator tips or surfaces. The capsule itself serves as both the product container and the application tool, eliminating the need for separate applicators with insufficient thermal mass. This integration ensures the frozen product is applied directly while maintaining its cooling effect.
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
The system provides a significant chilling effect during application while preventing product degradation and reducing mess, as the frozen product adheres to the applicator head and melts evenly onto the skin, allowing for efficient use and disposal.
Implementation Method 1
When not in use, the reservoir houses one or more products and one or more applicator heads. In use, a product in the reservoir is frozen, which causes the product to bond to the applicator head.
Implementation Method 2
As it melts from the heat of the skin, the product can be spread on the skin.
Implementation Method 3
a frozen product can deliver a much more significant chilling effect to the skin, than a merely chilled product or product applicator

AI summary
A disposable unit dose package for frozen cosmetic or personal care products that can provide a chilling effect during application. The main components of the package are a reservoir and an applicator. The reservoir may be interiorly divided to hold more than one product. The applicator comprises a handle and one or more applicator heads depending from the handle. In use, a product in the reservoir is frozen, which causes the product to bond to the applicator head. The handle is used to lift the frozen product out of the reservoir, and draw the frozen product over the skin. As it melts from the heat of the skin, the product can be spread on the skin.
