Cosmetic Sample Packaging Segmented Cover Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product packaging with applicators faces challenges in easy opening, maintaining product integrity, minimizing moisture loss, and preventing microbial contamination, while also being compact, easy to use, and economical.
Innovation Solution
A packaging design featuring a shell with interconnected cavities and a cover that is welded around the cavities, allowing for easy opening by peeling away a section without compromising the integrity of the product, using a reinforcing weld bead to prevent simultaneous opening of the second weld, and a multilayer material to prevent leakage and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the packaging uses flexible and elastic material for front and rear walls, then the packaging can be easily opened, but the walls cannot both be held open during extraction of the applicator, requiring user dexterity and risking contamination
Solution Approach 1:
The packaging shell is divided into a first portion and a second portion connected by a hinge, allowing independent manipulation of each portion. The cover is segmented into a first section and second section, enabling the first section to be peeled away while the second section remains attached to protect the applicator.
Solution Approach 2:
The hinge acts as an intermediary mechanism between the first and second portions of the shell, allowing controlled movement and positioning. This enables the first portion to be held open while the second portion remains closed, protecting the applicator without requiring complex user dexterity.
2Ease of operation
If perforations are made in the cover to enable peeling, then the cover can be easily opened, but the packaging becomes fragile and can be pierced causing leakage and contamination
Solution Approach 1:
The peeling function is extracted from the entire cover and concentrated in a specific first section of the cover. This first section is designed with peeling characteristics while the second section maintains full integrity and sealing capability, eliminating the fragility issue throughout the entire cover.
Solution Approach 2:
Different sections of the cover have different properties: the first section has peeling characteristics for easy opening, while the second section maintains full sealing integrity. This local differentiation allows easy opening without compromising overall packaging reliability.
3Ease of operation
If the cover is completely peeled away to access the applicator, then the applicator can be easily removed, but the cosmetic substance may leak and the product may be contaminated
Solution Approach 1:
The cover is divided into a first section that can be peeled away for applicator access and a second section that remains attached to maintain sealing. This segmentation allows the applicator to be accessed while the second section continues to protect the cosmetic substance from contamination.
Solution Approach 2:
The second section of the cover remains nested over the second portion of the shell, maintaining the protective enclosure even after the first section is peeled away. This nested configuration ensures continuous protection of the cosmetic substance while allowing applicator removal.
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 packaging allows for easy, hygienic opening and removal of the applicator without risking contamination or product loss, maintaining the product's integrity and microbial safety, while being cost-effective and adaptable to various cosmetic products.
Implementation Method 1
The packaging comprises a reinforcing means, in particular a weld bead, separating the first and second portions, the reinforcing means being intended to prevent the dewelding of the second weld when the dewelding of the first weld occurs during the peeling away of the cover

AI summary
A sample cosmetic product (1) having an applicator including a shell (7), incorporating a first portion (13) with a first cavity (10) and a second portion (15) with a second cavity (13) connected together so as to enable the reception of an applicator. A cover (8) is positioned on the shell to cover the first cavity and the second cavity, the cover welded around the first cavity on the first portion of the shell forming a first weld (26), and around the second cavity of the second portion of the shell forming a second weld (27). The first weld is configured to be dewelded by peeling away the cover to enable the opening of the first cavity. The packaging has a reinforcing mechanism separating the first portion and the second portion, the reinforcing mechanism is configured to prevent the dewelding of the second weld.
