Guide Cover Sealing Structure for Controlled Paint Cup Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint mixing cups suffer from issues such as large openings leading to paint pollution, difficulty in controlling the flow of paint, and environmental contamination due to continuous volatilization of toxic substances, especially when pouring paint into smaller fluid supply devices.
Innovation Solution
A painting mixing cup with a guide function featuring a ring-shaped sealing surface, a clamping sealing structure, and a guide channel with a balanced air hole, allowing for precise control of paint flow and reducing pollution by ensuring a sealed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening of the paint mixing cup is made large to facilitate pouring, then the ease of operation is improved, but the cup wall and opening are polluted in a large area and paint spills increase
Solution Approach 1:
The patent introduces a guide cover as an intermediary component between the paint mixing cup and the pouring process. The guide cover includes a guide channel that directs paint flow along a controlled path, preventing paint from contacting the cup wall and opening. This mediator structure enables both large opening for ease of operation and controlled pouring to minimize pollution.
2Productivity
If the volume of the paint mixing cup is increased to reduce the number of pouring operations, then the productivity is improved, but the flow control becomes more difficult and paint waste increases when dumping
Solution Approach 1:
The guide cover acts as a flow control intermediary that manages paint discharge from large-volume cups. The guide channel design allows operators to control paint flow rate by adjusting the cup angle, preventing uncontrolled dumping even when the cup is full. This enables efficient batch mixing while maintaining precise flow control.
Solution Approach 2:
The patent employs dynamic flow control where the guide channel's outlet orientation and opening can be adjusted during operation. The guide cover can be rotated or tilted to change the pouring angle and flow rate, allowing adaptive control of paint discharge from large-volume cups to match the receiving container's capacity.
3Ease of operation
If the paint mixing cup is kept open for repeated pouring operations, then the ease of operation is improved, but toxic substances continuously volatilize and pollute the workplace environment
Solution Approach 1:
The guide cover serves as a sealing intermediary that closes the paint mixing cup when not in use. The guide cover includes a sealing structure that fits onto the cup opening, preventing toxic substances from volatilizing into the workplace environment while allowing quick access when pouring is needed. This mediator enables the cup to remain sealed during storage and transport.
4Ease of operation
If a paint leakage port is directly arranged on the opening of the paint mixing cup, then the flow control is improved, but the cup cannot be sealed and paint cannot be poured out continuously
Solution Approach 1:
The guide cover is designed as a multi-functional component that combines flow control, sealing, and guiding functions. The guide channel provides controlled paint flow, the sealing structure prevents leakage when closed, and the guide cover can be quickly removed for pouring. This universal component eliminates the need for separate leakage ports while maintaining both flow control and sealing capabilities.

AI summary
A painting mixing cup with a guide function, including a ring-shaped sealing surface that is arranged on an inner surface of an upper edge of the cup body, and a clip angle between the ring-shaped sealing surface and a vertical plane is 2°˜6°; the cup body is arranged with a guide cover, and the guide cover includes a clamping sealing structure, and an inner surface of a first ring-shaped plate of the clamping sealing structure cooperates with the ring-shaped sealing surface to form a sealing structure. A reinforcing portion is arranged at the middle part of the guide cover. Meanwhile, the balanced air hole is opened when pouring paint, and the diameter of the guide channel is much smaller than that of the paint mixing cup, so that the user can accurately control the pouring speed of the paint.
