Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container caps with separate use trace belts are difficult to recycle due to increased plastic waste and cumbersome separation operations, contributing to environmental pollution.
Innovation Solution
A container cap design featuring a main body part, cover part connected by a hinge, and a separation part with a fixing mechanism that allows easy detachment and integration, facilitating recycling and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate use trace belt is used in the container cap, then the cover part can open and close the upper opening, but the plastic waste increases and recycling becomes difficult
Solution Approach 1:
The patent merges the use trace belt and the container cap into a single integrated structure formed by one-piece injection molding. The belt is no longer a separate component but is integrally formed with the cap body, eliminating the need for separate plastic materials and facilitating unified recycling of the entire cap assembly.
Solution Approach 2:
The integrated belt structure serves multiple functions: it acts as both the opening/closing mechanism and the use trace indicator, while also being part of the recyclable container cap structure. This multi-functionality reduces the number of separate components and promotes environmental sustainability.

The belt is no longer a separate component but is integrally formed with the cap body, eliminating the need for separate plastic materials and facilitating unified recycling of the entire cap assembly.
3Loss of substance
If the container cap is made as an integrated structure, then recycling is facilitated, but the sealing force for the container may be reduced
Solution Approach 1:
The patent applies local quality by providing a sealing ring made of elastomeric material at the specific location where sealing is required (the interface between the cap and container). This localized elastomeric sealing element provides reliable sealing force, while the rest of the cap structure remains as a simple integrated plastic component for easy recycling.
Solution Approach 2:
The patent uses composite materials by combining rigid plastic for the cap structure with elastomeric material for the sealing ring. This combination allows the cap to maintain structural integrity for recycling while the elastomeric portion provides the necessary sealing force to prevent leakage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies waste plastic collection for recycling and enhances sealing efficacy by integrating components for easy use and airtight closure, reducing environmental waste and ensuring secure storage of contents.
Implementation Method 1
a cover part (200) which is integrally connected to the main body part (100) by a hinge part (530) to open and close an upper opening of the main body part (100) by hinge rotation
Implementation Method 2
a fixing part (400) disposed on the cover part (200) so that the separation part (300) is fixedly coupled thereto

AI summary
Provided are a container cap coupled to the mouth of a container in which contents are contained; and a container to which the container cap is coupled. The container cap includes: a main body part coupled to a container inlet of a container and having an opening formed on an upper side thereof; a cover part connected to the main body part by a hinge part and opening and closing an upper opening of the main body part by hinge rotation; a separation part connected to the cover part by a first connection part and connected to the main body part by a second connection part detachably; and a fixing part formed on the cover part so that the separation part is fixedly coupled thereto after the second connection part is separated by a user's manipulation so that the cover part can be separated from the main body part.
