Paper Funnel Packaging Container with Sealed Folded Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging containers with funnel components, especially those made of paper, face issues with strength, buckling, and adhesion of sticker labels on non-flat surfaces, leading to content spillage and design degradation due to pressure changes.
Innovation Solution
A packaging container design featuring a funnel component formed by a sheet member with a sealant layer, including a folded portion for enhanced strength, and a sealing lid with a specific adhesion pattern to prevent content spillage and maintain design integrity under pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a paper-based funnel component is used to reduce cost and improve environmental friendliness, then manufacturing cost decreases and environmental impact is reduced, but the strength and resistance to buckling deteriorates
Solution Approach 1:
The patent applies composite materials by combining paper with plastic layers to form a laminated sheet member. This composite structure maintains the environmental friendliness and cost-effectiveness of paper while adding the strength and buckling resistance of plastic, directly resolving the contradiction between using paper and maintaining structural strength.
2Reliability
If the funnel component projects outward to prevent content spillage, then content spillage is prevented, but the funnel component becomes more susceptible to buckling under external pressure
Solution Approach 1:
The laminated composite structure of paper and plastic provides enhanced buckling resistance while maintaining the necessary projection distance for spillage prevention. The plastic layers reinforce the paper structure, allowing it to withstand external pressures without collapsing, thus resolving the contradiction between spillage prevention and buckling resistance.
3Adaptability or versatility
If sticker labels are applied to non-flat surfaces of the sealing lid, then design information can be displayed, but the labels experience crinkling and lifting
Solution Approach 1:
The patent applies local quality by creating a flat adhesion region on the sealing lid where sticker labels can be applied without crinkling or lifting. This localized flat area provides a stable surface for label application, while the rest of the sealing lid can maintain its functional non-flat structure, thus resolving the contradiction between design display and label stability.
4Ease of operation
If the sealing lid is designed to be cut along perforation lines for content transfer, then ease of operation is improved, but the structural integrity before cutting is compromised
Solution Approach 1:
The patent applies segmentation by incorporating perforation lines that allow the sealing lid to be cleanly divided into segments for content transfer. The perforation lines are designed to maintain structural integrity until cutting is needed, at which point they enable easy separation, thus resolving the contradiction between operational ease and structural integrity.

AI summary
A funnel component, and a packaging container using the funnel component are provided. A funnel component includes: a funnel portion having a diameter that is increased from a narrow opening side toward a wide opening side; a discharge portion that connects with an end portion on the narrow opening side; and a side wall portion that surrounds an opening portion, on the wide opening side, of the funnel portion, connects with the funnel portion, and is fitted into the container body. The funnel component is integrally formed by a sheet member including paper and sealant layer. A folded portion is formed, by the sheet member being folded back and welded over entire circumference, at an opening portion of the discharge portion. The packaging container is formed by the funnel component being fitted into a container body having an open end, a bottom portion, and a side wall.
