Refillable Cosmetic Stick Container With Press-to-Detach Lift Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers for stick-type products are not conveniently recyclable, leading to resource waste, and their refill process is cumbersome due to inconvenient handling.
Innovation Solution
A container design featuring a lifting/lowering part, guide part, and rotational part that allows easy separation and refilling by exposing a lower end of the guide part for simple pressing, while maintaining aesthetic appeal by hiding components from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the container is designed for refilling, then resource waste is reduced, but the operating convenience is lowered due to cumbersome handling
Solution Approach 1:
The container is divided into separable components: the container body and the cap assembly. This segmentation allows the cap to be detached and reattached easily during refilling, reducing the complexity of the refilling operation while enabling resource reuse.
Solution Approach 2:
The container incorporates a self-opening mechanism where the cap can be automatically opened or detached through simple user interaction. This self-service feature reduces the manual effort required for refilling, improving operating convenience while maintaining the refillable design for resource conservation.
2Ease of operation
If the lower end of the guide part is exposed for easy separation, then ease of operation is improved, but the aesthetic appearance is compromised
Solution Approach 1:
A guide part is introduced as an intermediary component between the container body and cap. This guide part features an exposed lower end that can be easily pressed or manipulated for separation, while the main body of the guide part remains concealed within the container structure, preserving aesthetic appearance.
Solution Approach 2:
Only the specific region of the guide part that needs to be exposed for operation is made visible, while other portions remain hidden. This localized exposure allows the functional requirement for easy separation to be met without compromising the overall aesthetic appearance of the container.
3Ease of operation
If the rotational part is made rotatable for lifting and lowering, then ease of operation is improved, but unintentional rotation may occur reducing reliability
Solution Approach 1:
A locking mechanism is incorporated that can preliminarily secure the rotational part in position. This locking feature prevents unintentional rotation during normal handling, while still allowing intentional rotation when the user needs to lift or lower the container contents.
Solution Approach 2:
The locking mechanism applies a preliminary counteracting force to prevent the rotational part from rotating unintentionally. This anti-action mechanism counterbalances any forces that might cause unwanted rotation, ensuring reliability while maintaining operational convenience when needed.

AI summary
According to an embodiment of the present invention, a contents container is provided. The contents container comprises: a lifting/lowering part including, at the top thereof, an accommodation portion for accommodating a content; a lifting/lowering guide part which is arranged to encompass at least a portion of the lifting/lowering part, and which guides the lifting/lowering of the lifting/lowering part; a rotational part which is coupled to the lower side of the lifting/lowering guide part so as to rotate in synchronization with the lifting/lowering guide part, and to which the rotational operation by a user to lift/lower the lifting/lowering part is applied; and a holding part having an upper end disposed outside the accommodation portion, and having a lower end disposed between the rotational part and the lifting/lowering guide part such that the rotational part can rotate relative thereto, wherein the lower end of the lifting/lowering guide part is detachably coupled to the rotational part and, when one region of the lower end of the lifting/lowering guide part exposed to the outside of the rotational part is pressed, the lifting/lowering part, the lifting/lowering guide part and the holding part can be integrally separated from the rotational part.
