Paper Lid Holding Structure for Sealable Drink Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper-based lids face challenges in maintaining sealability and ease of use due to lower elasticity and moldability compared to plastic, leading to potential leakage and complex operation for opening and closing beverage outlets.
Innovation Solution
A paper-based lid with a top lid, a lid piece, a holding portion, and a holding reception portion that allows the lid piece to be easily opened and closed by operating the holding portion, maintaining the opening state without touching the contents, and enabling simple multiple operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a paper-based lid is used to replace plastic lid, then environmental friendliness is improved, but sealability and moldability deteriorate
Solution Approach 1:
The lid is divided into multiple functional parts: a lid body with an opening, a lid piece that closes the opening, a holding portion to maintain the opened state, and a holding reception portion to receive the holding portion. This segmentation allows each part to perform its specific function optimally while maintaining overall sealability.
Solution Approach 2:
The lid piece is designed to be movable relative to the lid body, transitioning between closed and opened states. The holding portion and holding reception portion work together to dynamically maintain the opened state without requiring continuous external force, enabling the lid to adapt to different usage states.
2Object-affected harmful factors
If a paper-based lid is used to replace plastic lid, then environmental friendliness is improved, but ease of operation deteriorates
Solution Approach 1:
The holding portion acts as an intermediary element between the user's hand and the lid piece. Instead of directly manipulating the lid piece, the user operates the holding portion, which in turn controls the lid piece's movement. This intermediary structure simplifies the opening and closing operations.
Solution Approach 2:
The holding portion and holding reception portion work together in a self-service mechanism where the holding portion automatically engages with the holding reception portion to maintain the opened state, eliminating the need for continuous user intervention or complex mechanical systems.
3Ease of operation
If the lid piece is held in opened position by holding portion, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The holding portion is extracted as a separate, simple component from the main lid structure. It is designed as a minimal element that can be easily formed from the same paper-based material, adding functionality without significantly increasing overall structural complexity.
Solution Approach 2:
The holding portion and holding reception portion utilize the flexibility and thin-film characteristics of paper-based materials to achieve the holding function through simple geometric configurations rather than rigid mechanical structures, thereby minimizing added complexity.

AI summary
Provided is a lid capable of easily taking out contents from an opening portion thereof, while securing sealability of a container. The lid includes a top lid made of a paper-based material, the top lid including: an opening portion communicating between the inside and the outside of the top lid; a lid piece formed to be capable of opening or closing the opening portion; and a holding portion for holding the lid piece in a state where the opening portion is opened; and the lid includes a holding reception portion configured to hold the holding portion in a state where the opening portion is opened.
