Tear-Off Cosmetic Container Structure Without Lift Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with lifting or lowering mechanisms are complex, costly, and environmentally harmful due to multiple components and materials like plastic or metal, making disposal difficult and contributing to pollution.
Innovation Solution
A container design featuring a packaging sheet with an accommodation space and a holder part that supports the container, allowing contents to be exposed by tearing off the packaging sheet without additional tools, with a tear-off thread and holder part to prevent detachment and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a conventional container with lifting or lowering mechanism is used, then the cosmetic composition can be continuously used, but the configuration becomes complex and manufacturing cost increases
Solution Approach 1:
The patent removes the complex lifting/lowering mechanism from the container system entirely. Instead of having mechanical components to move the cosmetic composition, the design extracts this function by allowing the cosmetic composition to be directly accessible through the open top of the container, eliminating the need for rotating members, sliding members, or other mechanical movement devices.
Solution Approach 2:
The container is divided into distinct functional components: a container body for holding the cosmetic composition, a cap for closing the container, and a packaging sheet for wrapping. This segmentation allows each component to perform its specific function independently without requiring complex interconnections or mechanical mechanisms for operation.
2Ease of operation
If a conventional container with multiple components is used, then the cosmetic composition can be lifted or lowered, but the manufacturing cost increases
Solution Approach 1:
The patent eliminates the need for expensive mechanical components such as rotating members, sliding members, and their associated mounting structures. By removing these components entirely and using a simple open-top container design, the manufacturing cost is significantly reduced while maintaining ease of operation for accessing the cosmetic composition.
Solution Approach 2:
The container is designed with simple, inexpensive materials that can be easily manufactured and disposed of. The use of basic container bodies, caps, and packaging sheets made from common materials reduces manufacturing costs compared to complex mechanical systems, accepting that the container may be discarded after use rather than being a durable, long-term product.
3Strength
If a conventional container made of plastic or metal is used, then the container can be made durable, but the components are difficult to separate for disposal causing environmental pollution
Solution Approach 1:
The container system is segmented into separate components (container body, cap, packaging sheet) that can be easily separated from each other. This segmentation allows each component to be disposed of independently and facilitates recycling or proper disposal, reducing environmental pollution compared to integrated plastic or metal containers that are difficult to separate.
Solution Approach 2:
The design accepts that the container components will be discarded after use, but structures them to be easily separable and recyclable. The simple construction with distinct components made from different materials allows for recovery and recycling of materials, reducing environmental impact compared to complex multi-material containers that are difficult to process for recycling.
4Reliability
If additional tools are used to access contents, then the container can be securely sealed, but portability and convenience of use decrease
Solution Approach 1:
The container is pre-designed with an open top that allows direct access to the cosmetic composition without requiring any additional tools or complex opening mechanisms. The cap serves as a simple cover that can be easily removed and replaced, providing sufficient sealing during storage while allowing convenient access during use, eliminating the need for knives, scissors, or other external tools.
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 design provides convenient and portable access to contents, prevents waste by not filling the lower end of the container, and allows easy gripping and sealing, reducing environmental impact through simpler materials like paper.
Implementation Method 1
At least one portion of the holder part may be made of an expandable/contractable material, and the at least one portion may expand after the at least one portion is inserted into the container part in a state in which a volume of the at least one portion is reduced.
