C-Shaped Pump Stopper Integrating Finger Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump dispensers require separate storage or disposal of pump stoppers and incur additional manufacturing costs and environmental impact due to the need for a finger-pressing member, which can also be inconvenient for users.
Innovation Solution
A detachable pump stopper with a C-shaped design that integrates as both a stopper and finger-pressing member, featuring a cylindrical shape with side openings and connecting pieces for easy insertion and deformation, allowing it to serve both functions without increasing the number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate finger-pressing member is added to the dispenser, then the dispenser can be operated during use, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The pump stopper is designed to perform multiple functions: it acts as a stopper during distribution/storage and as a finger-pressing member during use. The C-shaped configuration with the press portion allows users to press the nozzle head through the press portion, eliminating the need for a separate finger-pressing member.
2Ease of operation
If a separate finger-pressing member is added to the dispenser, then the dispenser can be operated during use, but manufacturing cost increases
Solution Approach 1:
The pump stopper is designed to perform multiple functions: it acts as a stopper during distribution/storage and as a finger-pressing member during use. The C-shaped configuration with the press portion allows users to press the nozzle head through the press portion, eliminating the need for a separate finger-pressing member.
3Ease of operation
If the pump stopper is removed after distribution, then the dispenser can be used, but the stopper must be disposed of or stored separately
Solution Approach 1:
The pump stopper is designed to perform multiple functions: it acts as a stopper during distribution/storage and as a finger-pressing member during use. The C-shaped configuration with the press portion allows users to press the nozzle head through the press portion, eliminating the need for a separate finger-pressing member.
Solution Approach 2:
The pump stopper is designed to remain in the dispenser after distribution and continue serving a functional purpose during use. By integrating the finger-pressing function into the stopper structure, the stopper is recovered as a useful component rather than being discarded or requiring separate storage.
4Device complexity
If the pump stopper is integrated with the attachment cap as a finger-pressing member, then the number of components is reduced, but it may disturb users who do not need the finger-pressing function
Solution Approach 1:
The pump stopper is designed to be detachable rather than permanently integrated. Users can remove the stopper if they do not need the finger-pressing function, providing flexibility and avoiding disturbance to users who prefer traditional operation methods.

AI summary
Provided is a pump stopper (E, F) including a substantially cylindrical-shaped stopper main body (35) provided with a side opening (38) in a manner such that the stopper main body (35) is C-shaped in an upper view thereof. The stopper main body (35) includes, on one of an upper end side and a lower end side thereof, a regulating portion (41) that prevents a tubular body (28) of a nozzle head (D) from being displaced downward, and, on another one of the upper end side and the lower end side thereof, a space portion (42) that allows the tubular body (28) of the nozzle head (D) to be displaced downward when the pump stopper (E, F) is inserted between a top wall (5) of an attachment cap (B) and the tubular body (28) of the nozzle head (D).
