Lid-Integrated Opening Button Maximizes Cosmetic Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compact cosmetics containers with opening/closing buttons integrated into the container body occupy valuable space, requiring intermediate containers and leading to frequent refilling due to reduced cosmetic capacity.
Innovation Solution
A compact cosmetics container design where the opening/closing button is formed on the lid, incorporating a rubber-based opening/closing tension member that releases the locking protrusion from the container body's recess, allowing the lid to be opened by a resilient part pressing the container body's upper surface, eliminating the need for an intermediate container and maximizing cosmetic space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening/closing button is installed on the container body with an intermediate container, then the opening/closing function is achieved, but the cosmetic receiving space is reduced and intermediate containers are required
Solution Approach 1:
The opening/closing button is merged with the container lid by forming it integrally on the outer surface of the lid. This eliminates the need for separate intermediate containers and assembly structures, maximizing the cosmetic receiving space within the container body while maintaining the opening/closing function through the button's locking protrusion that engages with the locking recess in the container body.
2Ease of operation
If the opening/closing button is installed on the container body, then the opening/closing function is achieved, but an intermediate container is required for assembly
Solution Approach 1:
The opening/closing button is formed integrally with the container lid as a single piece, eliminating the need for intermediate containers and complex assembly structures. The button includes a locking protrusion that directly engages with the locking recess in the container body, simplifying the overall device structure while maintaining the opening/closing function.
3Reliability
If the locking protrusion is engaged with the locking recess, then the container lid is securely closed, but the coupling structure is strained with repetitive forced attachment and detachment
Solution Approach 1:
The opening/closing button is designed with elastic resilience, allowing it to dynamically engage and disengage from the locking recess. When the button is pressed, it releases from the locked state; when released, it returns to its original position and re-engages with the locking recess. This dynamic mechanism reduces stress on the coupling structure compared to forced attachment and detachment.
4Volume of stationary object
If the opening/closing button is formed on the container lid, then the cosmetic receiving space is maximized, but the opening/closing mechanism must be integrated into the lid structure
Solution Approach 1:
The opening/closing button is formed integrally with the container lid as a single piece, with the button structure including a locking protrusion that engages with the locking recess in the container body. This integral design maximizes the cosmetic receiving space by eliminating separate components while the locking mechanism provides secure closure through the engagement between the button's protrusion and the container body's recess.
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
This design minimizes the space occupied by the opening/closing button, allowing for increased cosmetic capacity and reducing the frequency of refilling, while maintaining a convenient and durable mechanism for opening and closing the container.
Implementation Method 1
an opening/closing tension member made of a rubber material is formed in the opening/closing button... a lid lifting resilient part of the opening/closing tension member resiliently presses the upper end surface of the container body to push the container lid upward

AI summary
The present invention relates to a compact cosmetics container having an opening/closing button formed in a container lid so that it is possible to eliminate the receiving space that the opening/closing button occupies in the container body and remove an intermediate container required for assembling the opening/closing button, whereby the cosmetics receiving space of the container body can be maximized to effectively accommodate more cosmetics therein, thereby minimizing the inconvenience of frequently refilling cosmetics; and an opening/closing tension member made of a rubber material is formed in the opening/closing button such that when the opening/closing button is pressed, the locking protrusion of the opening/closing button is released from the locking recess of the container body, and a lid lifting resilient part of the opening/closing tension member resiliently presses the upper end surface of the container body to push the container lid upward, thereby opening the container lid.
