Refillable Cosmetic Packaging With Elastic Interlocking Reliefs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic packaging devices are not refillable, leading to aesthetic and cost issues, with previous solutions either deforming the insert or requiring tools for removal, resulting in product loss or inefficiency.
Innovation Solution
A refillable device with a removable container that uses elastic interlocking reliefs and a lid to securely attach and detach the container, allowing for easy replacement without risking product loss, featuring a ferrule and complementary reliefs for secure attachment and reversible removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the insert is made removable by forming a small hole in the bottom of the casing, then the packaging becomes refillable, but the insert may be deformed and cosmetic product may be expelled
Solution Approach 1:
The invention divides the packaging system into three separable components: an outer casing, a removable insert, and a lid. The insert can be independently removed from the casing through an opening at the bottom, allowing refillability without deforming the insert or expelling product. This segmentation enables the insert to be handled separately during refilling operations.
Solution Approach 2:
The lid is designed to seal the outlet opening of the casing before the insert is removed. This preliminary sealing action prevents cosmetic product from being expelled during the insert removal process. The lid remains in place on the casing while the insert is extracted through the bottom opening, ensuring product containment throughout the refilling operation.
2Ease of operation
If a tool is used to push the insert from below through the hole, then the insert can be removed, but the operation becomes complex and may still deform the insert
Solution Approach 1:
Instead of pushing the insert from below through a small hole as in prior art, the invention inverts the approach by providing a large opening at the bottom of the casing through which the insert can be easily withdrawn. The insert is designed to be pulled or slid out through this opening rather than pushed through a small hole, eliminating the need for tools and reducing the risk of deformation.
3Shape
If the lid is made aesthetic with expensive materials, then the packaging appearance is improved, but the cost increases
Solution Approach 1:
The invention separates the aesthetic function from the containment function by making the lid removable and replaceable. The outer casing and insert can be made from cost-effective materials while the lid, which provides the primary aesthetic appearance when the product is in use, can be made from premium materials. Users can replace the lid with different aesthetic covers or choose simpler lids for refills, separating the cosmetic packaging cost from the functional packaging.
4Reliability
If the insert is securely attached to prevent accidental removal, then reliability is improved, but the ability to refill is reduced
Solution Approach 1:
The invention creates a dynamic attachment system where the insert can be easily inserted into and removed from the casing through the bottom opening. The attachment is simple enough to allow user removal for refilling but provides sufficient security during normal use. The lid further secures the insert in place during storage and transport, creating a multi-stage attachment system that adapts to different usage states.

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 solution enables a refillable and aesthetically pleasing packaging system where the removable container can be easily replaced and reattached without deforming or expelling the cosmetic product, ensuring secure closure and efficient refilling.
Implementation Method 1
the removable container being attached to the outer casing by the elastic interlocking of complementary reliefs
Implementation Method 2
a lid adapted to seal closed the outlet of the housing in the outer casing

AI summary
A refillable device for packaging cosmetic product, comprising a removable container containing cosmetic product, an outer casing defining a housing for receiving the removable container, the housing for receiving the removable container being open at an outlet in the outer casing, and a lid adapted to seal closed the outlet of the housing in the outer casing. The removable container is attached to the outer casing by the elastic interlocking of complementary reliefs. The removable container can be reversibly removed from the outer casing. The lid is adapted to be attached to one among the lid and the removable container so as to lock in place the elastic interlocking of the complementary relief portions.
