Paper Closure with Integrated Sealing Element for Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for closures made of paper do not integrate a sealing element effectively, lacking guidance on how to incorporate a sealing element into a paper-based closure.
Innovation Solution
A method for making a closure comprising a paper-based closure body and an inner sealing element, where the sealing element is attached to the closure body and remains attached to the container after the first use, allowing the closure body to be removed and reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a closure body is made of paper to reduce environmental impact, then the environmental friendliness is improved, but the ability to integrate a sealing element effectively is worsened
Solution Approach 1:
The closure is divided into separate functional components: a paper-based closure body and a separate sealing element. The sealing element is integrated into the paper closure body through a laminated structure, allowing each component to perform its specific function while maintaining the environmental benefits of the paper material.
Solution Approach 2:
The invention uses composite material construction by laminating a sealing element onto the paper closure body. This creates a multi-layer structure that combines the environmental advantages of paper with the sealing properties of the sealing element, effectively resolving the contradiction between material sustainability and functional performance.
2Duration of action of moving object
If the inner sealing element remains attached to the container after first use, then the closure can be reused, but the complexity of the closure structure increases
Solution Approach 1:
The closure structure is segmented into a reusable closure body and a disposable sealing element. The sealing element is designed to remain on the container after the closure body is removed, enabling the closure body to be reused while the sealing element is discarded. This segmentation achieves reusability without requiring the entire closure structure to be complex.
Solution Approach 2:
The sealing element is designed as a disposable component that remains attached to the container after use. By making the sealing element disposable rather than reusable, the overall closure structure can be kept simple while still achieving reusability of the main closure body, reducing the need for complex retention mechanisms.

AI summary
Method for making a closure for closing a container, the closure including a closure body made of paper and an inner sealing element attached to the closure body, the method includes the following steps: providing a sheet material including at least a paper layer and a sealing layer, removing an excess portion of the sealing layer from the sheet material so that the remaining portion of the sealing layer forms the inner sealing element in the sheet material; by use of a forming device, forming the sheet material, in which the inner sealing element has been previously formed, to realize the closure body having the inner sealing element attached.
