Transparent Cosmetic Container with Profiled Inner Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers fail to effectively showcase the color and additional shiny effects of liquid cosmetic products while maintaining a high-quality, durable design, especially when containing chemically aggressive ingredients.
Innovation Solution
A two-piece container design made from transparent or translucent plastic material with a liquid-tight joint and a profiled inner wall, allowing the inner profile to be visible from the outside, providing a pleasing optical effect without compromising usability, and featuring a welded or adhesive joint for chemical resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent or translucent container is used to display the color of cosmetic product, then the visual appeal and color identification are improved, but the structural strength and chemical resistance are worsened
Solution Approach 1:
The container employs a composite structure combining transparent plastic material with metallic reinforcement elements (screw cap and/or bottom element). This allows the transparent portions to provide visual appeal and color display while the metallic components contribute structural strength and chemical resistance, resolving the contradiction between transparency and durability.
2Ease of manufacture
If a one-piece container design is used, then the manufacturing simplicity is improved, but the optical effect and structural flexibility are worsened
Solution Approach 1:
The container is divided into multiple separately manufacturable components (container body, screw cap, bottom element) that are subsequently assembled. This segmentation enables each component to be optimized independently - the transparent container body can be molded to showcase the product while metallic components can be separately fabricated and attached, achieving both manufacturing feasibility and superior optical effects through material contrast and structural design.
3Loss of information
If a transparent container material is used, then the color identification is improved, but the protection of cosmetic product is worsened
Solution Approach 1:
The container uses a composite design where transparent plastic portions allow full color identification of the cosmetic product, while metallic components (screw cap and/or bottom element) provide enhanced protection against chemical degradation and contamination. This composite approach resolves the contradiction by assigning different protective functions to different materials within the same container system.
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 container design ensures a secure, chemically resistant seal and an attractive optical effect, maintaining the cosmetic product's appearance and usability, even with aggressive ingredients, while preventing label or logo removal issues.
Implementation Method 1
a transparent or translucent material, in particular a plastic material, is provided as container material
Implementation Method 2
Alternative joints such as an adhesive joint are however also conceivable. This way, a permanently liquid-tight joint may be obtained

AI summary
The invention relates to a container for receiving a liquid cosmetic product, in particular a colored cosmetic product for the lips, eyelids, fingernails or the like. A transparent or translucent material is provided as container material. The container is of a two-piece design comprising a first container element and a second container element, wherein the first and the second container element are securely joined together in a liquid-tight manner. The first container element has an inner wall with a profile.
