Plant-Leaf Packaging Base With Adhesive-Free Folding-Lid Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging technologies struggle to adapt flexibly to different articles while ensuring safe transport and often rely on adhesive connections that are not environmentally friendly.
Innovation Solution
A packaging system comprising a three-dimensionally shaped packaging base made of plant material, a container support surface, a container edge, and a folding lid with lateral folding elements that secure to the base without adhesives, using a banderol for stability, and optionally reinforced with connecting elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive connections are used to secure the packaging lid to the base, then the lid is firmly fixed, but the packaging becomes less environmentally friendly and harder to recycle
Solution Approach 1:
The harmful adhesive substance is completely removed from the packaging system. The lid is secured to the base using only mechanical interlocking through the folding elements that engage with the container rim, eliminating any chemical adhesives from the construction.
Solution Approach 2:
Chemical bonding (adhesive) is replaced with a mechanical fastening system. The folding elements create a physical interlock with the container rim through geometric engagement, providing secure fixation without any chemical substances.
2Reliability
If a rigid fixed lid structure is used, then the lid remains stable during transport, but the packaging cannot be easily opened for access
Solution Approach 1:
The lid structure transitions from a fixed rigid state during transport to a easily openable state during use. The folding elements provide mechanical stability when closed but allow controlled opening by overcoming the folding resistance, enabling easy access to the packaged item.
Solution Approach 2:
The lid is divided into a cover element and lateral folding elements that can move relative to each other. This segmentation allows the lid to maintain structural integrity when closed while enabling easy opening through the folding mechanism.
3Reliability
If the packaging lid is designed to fit tightly on the base, then accidental slipping is prevented, but the packaging becomes less adaptable to different article sizes
Solution Approach 1:
The packaging base has different geometric zones: a container support surface for holding the article and corner regions for securing the lid. The folding elements engage specifically with the corner regions, providing localized anti-slipping functionality without constraining the overall packaging dimensions to different article sizes.

AI summary
The invention relates to packaging for an article, comprising a three-dimensionally shaped packaging base (1) made of leaf material from a plant; a base support surface (2) formed and configured on the three-dimensionally shaped packaging base (1) to receive an article to be packaged; a base rim (3) which, as part of the three-dimensionally shaped packaging base (1), surrounds the base support surface (2) and thereby forms a corner region (5) between the base support surface (2) and a proximal edge section of the base rim (3) with respect to the base support surface (2); and a packaging lid (6) made of a recyclable material, designed as a folding lid, in which lateral folding elements (7) are integrally formed on a cover element (9) and are arranged in a folded position to form a receiving space in the packaging lid (6);wherein the packaging lid (6) is arranged on the base support surface (2) such that the receiving space opens towards the base support surface (2) and distal edge sections of the lateral folding elements (7) come into contact with the cover element (9) in the corner area (5), so that the packaging lid (6) is fixed in its relative position on the base support surface (2). Furthermore, a packaged article is disclosed.
