Closure With Hinged Locking Protrusions for Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closures for containers, such as screw tops and cork closures, face challenges in providing both convenient use and sufficient airtightness, especially when dealing with contents under pressure, and can be difficult for children to open or may not maintain airtightness effectively.
Innovation Solution
A closure system featuring a sealing portion with locking protrusions connected to a hinge, a cover portion that is vertically movable, and fixing protrusions to support the locking protrusions, allowing for one-touch opening and closing while ensuring airtightness through a combination of upward and downward movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw top is strongly fastened to prevent contents from leaking out, then airtightness is improved, but the fastened screw top may not be easily opened again
Solution Approach 1:
The closure is divided into multiple functional components: a sealing portion with locking protrusions for airtightness, a cover portion for operation, and a hinge connecting them. This segmentation allows each part to perform its specific function independently - the locking protrusions maintain reliable sealing while the hinge enables easy opening through a simple lifting motion.
Solution Approach 2:
The hinge introduces dynamic movement capability to the closure system. The locking protrusions can move between locked and unlocked positions through the hinge's rotational motion, allowing the closure to transition between tightly sealed and easily opened states. This dynamic mechanism resolves the contradiction by enabling both strong fastening and easy opening.
2Reliability
If a cork closure is used to ensure excellent airtightness, then sealing performance is improved, but the cork closure may not be easily opened
Solution Approach 1:
The invention replaces the traditional cork closure mechanism with a modern mechanical system consisting of a hinge and locking protrusions. This mechanical substitution maintains excellent airtightness through the locking protrusions engaging with the container aperture while enabling easy opening through the hinge's rotational motion, eliminating the difficulty of opening corks.
3Ease of operation
If a closure is designed to be opened by just one touch for convenient use, then ease of operation is improved, but airtightness may not be sufficient
Solution Approach 1:
The invention merges multiple functions into a single integrated closure structure: the sealing portion provides airtightness, the locking protrusions maintain the seal, the hinge enables one-touch operation, and the cover portion provides user interface. This merging allows the closure to achieve both convenient one-touch opening and reliable airtightness simultaneously.
Solution Approach 2:
The locking protrusions are designed to automatically engage with the container aperture when the closure is closed, providing self-locking functionality. This self-service mechanism ensures reliable airtightness without requiring additional fastening operations, while the hinge enables easy opening through a simple lifting motion that disengages the locking protrusions.

AI summary
A closure and a container having the same closure are provided. The closure includes a sealing portion assembled to an aperture of a container to seal the container; a plurality of locking protrusions, each lock protrusion connected to a hinge extending from a lower rim of the sealing portion to protrude inwards and fixed to a locking flange formed on the container; a cover portion having a ring shape and assembled to an outside of the sealing portion to be vertically movable with respect to the sealing portion; and a plurality of fixing protrusions protruding from an inner circumferential surface of the cover portion to support the locking protrusions.
