Vessel Cap Cutter and Hook for Sealing Member Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vessel caps require manual removal of sealing members, which can be inconvenient and lead to sanitary issues due to strong adhesion forces, and often result in environmental pollution.
Innovation Solution
A vessel cap with an integrated sealing member removing unit that automatically cuts and stores the sealing member using a movable pressing plate with cutters and a hooking mechanism, allowing for easy detachment and storage within the cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of sealing member is used, then device complexity is reduced, but ease of operation deteriorates due to strong adhesion forces requiring additional tools or repeated actions
Solution Approach 1:
The sealing member removal function is merged with the vessel cap by integrating a cutter and hooking member directly into the cap structure. The cutter is formed at the edge of the pressing plate, and the hooking member is downwardly protruding from the pressing plate, allowing the cap to both open and remove the sealing member in a single integrated operation.
Solution Approach 2:
The vessel cap performs the sealing member removal function itself without requiring external tools or additional user actions. When the user pulls the handgrip to open the cap, the integrated cutter automatically cuts the sealing member and the hooking member automatically hooks and removes it, making the system self-servicing.
2Ease of operation
If additional tools are used for sealing member removal, then ease of operation improves, but device complexity increases due to additional components

3Ease of operation
If sealing member is removed manually, then device complexity is reduced, but sanitary conditions deteriorate due to user hand contact with vessel inlet
Solution Approach 1:
The vessel cap performs the sealing member removal function itself without requiring external tools or additional user actions. When the user pulls the handgrip to open the cap, the integrated cutter automatically cuts the sealing member and the hooking member automatically hooks and removes it, making the system self-servicing.
4Ease of operation
If sealing member is not stored in vessel cap, then device complexity is reduced, but environmental pollution increases due to discarded sealing member
Solution Approach 1:
The removed sealing member is stored inside the vessel cap, which acts as a container. The cap encompasses both its opening function and the storage function for the removed sealing member, creating a nested arrangement where one object (sealing member) is contained within another (vessel cap).

AI summary
A vessel cap is comprised of a body mounted at a vessel inlet through which a liquid material stored in a vessel is discharged outwardly and having a certain space therein. A pressing plate is disposed in the body to be movable in upper and lower directions. A cutter is formed at an edge of a lower surface of the pressing plate in a circumferential direction for penetrating a sealing member when the pressing plate is pressed and which cuts the sealing member when the body is rotated. A hooking member downwardly protrudes at the lower surface of the pressing plate for storing the sealing member cut by the cutter in the body. A connection portion is formed between an outer circumferential surface of the pressing plate and an inner circumferential surface of the body for guiding the pressing plate to be moved in upper and lower directions.
