Rotating Outer Cap Structure for Vessel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screw-coupling structures for vessel caps require inconvenient repeated rotation to open and close, leading to wastage of cosmetics when using integrated tools like pipettes or mascara sticks, as users must separate the cap from the vessel, causing liquid to be wasted.
Innovation Solution
A cap structure featuring an inner and outer cap with a fixing groove, operating part, driving part, and elastic member, allowing the cap to be opened or closed by rotating the outer cap at a predetermined angle, enabling the integrated tool to be used closer to the vessel's floor, thus minimizing liquid wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-coupling structure is used to couple the cap with the vessel, then the cap can be securely attached to open/close the vessel, but the user must inconveniently rotate the cap several times to open/close it
Solution Approach 1:
The cap structure is divided into an inner cap and an outer cap that can rotate independently. The inner cap is coupled to the vessel while the outer cap serves as the operating interface. This segmentation allows the opening/closing function to be separated from the cosmetic tool, enabling simple rotation of the outer cap without moving the integrated tool.
2Ease of operation
If the cap is separated from the vessel to use the integrated pipette or mascara stick, then the tool can be accessed, but the user must use the tool with its end portion spaced apart from the vessel floor, causing liquid wastage
Solution Approach 1:
The cap is segmented into an inner cap (coupled to vessel) and an outer cap (rotating operating part). The cosmetic tool is integrated with the inner cap, allowing it to remain close to the vessel floor while the outer cap rotates independently for opening/closing operations.
Solution Approach 2:
The outer cap acts as an intermediary operating interface between the user and the vessel closure mechanism. By rotating the outer cap instead of the entire cap assembly, the user can open/close the vessel while keeping the cosmetic tool's application end close to the liquid, eliminating the need to separate the cap and preventing liquid wastage.
3Adaptability or versatility
If the cosmetic tool is integrated with the cap, then the tool is always attached for use, but the user must separate the cap from the vessel to use the tool, causing inconvenience and liquid wastage
Solution Approach 1:
The cap assembly is segmented into an inner cap (with integrated cosmetic tool) and an outer cap (rotating operating interface). This allows the cosmetic tool to remain integrated with the vessel-coupling portion while the operating portion rotates independently, enabling tool access without cap separation.
Solution Approach 2:
The outer cap serves as an intermediary that provides the opening/closing function without requiring movement of the inner cap or the integrated cosmetic tool. This mediator structure allows the tool to remain in its optimal position for liquid access while enabling cap operation.
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 cap structure allows for simple opening and closing of the cap by rotating it at a specific angle, ensuring that the integrated tool can be used effectively, reducing cosmetic wastage by allowing the liquid to be used from the vessel's floor without overturning.
Implementation Method 1
an elastic member having elasticity to push the driving part outward from a circumferential center
Implementation Method 2
a moving guiding surface formed at one outer surface of the driving part corresponding to the fixing guiding surface of the inner cap such that the moving guiding surface makes sliding-contact with the fixing guiding surface

AI summary
Provided is a cap structure for a vessel, which can be coupled with the vessel to open or close the vessel. The cap structure includes an inner cap coupled with an upper end portion of the vessel, an outer cap fitted around an outer-diameter surface of the inner cap, a component inserted into the outer and inner caps, at least one fixing groove extending downward from an upper end portion of the inner cap, an operating part inserted into the inner cap, a driving part formed by partially cutting an upper end portion of the operating part in a vertically downward direction, a rotational member allowing the driving part to reciprocate about the bending groove, and a detachable member to lock or release the component. The cap opens or closes the vessel by fixedly attaching the component to the cap disassembled from the vessel or separating the component from the cap.
