Leaf Material Packaging Bottom With Inward Flaps For Secure Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for articles, such as foodstuffs, often struggle with securely fixing the packaging cover to the packing bottom, which can lead to instability and potential damage during transport.
Innovation Solution
A packaging system comprising a three-dimensionally shaped packing bottom made of leaf material with a rough surface and a packaging cover with inwardly protruding flaps that encompass the bottom edge of the packing bottom, providing improved fixability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the packaging cover is simply placed on the packing bottom, then the packaging is easy to assemble, but the fixability and stability during transport is insufficient
Solution Approach 1:
The packaging cover is divided into multiple flaps that can be folded inward to encompass the bottom edge. This segmentation allows the cover to achieve secure fixation through the distributed engagement of multiple flaps with the bottom edge, while maintaining a relatively simple overall structure that can be easily assembled.
Solution Approach 2:
The flaps are designed to be foldable, transitioning from a flat state during assembly to an engaged state during fixation. This dynamic element allows the packaging cover to adapt its configuration - simple during assembly, then secure during transport - resolving the contradiction between ease of assembly and fixation reliability.
2Reliability
If smooth surfaces are used for the packing bottom and packaging cover, then the manufacturing is easier, but the gripping forces and fixability are reduced
Solution Approach 1:
The leaf material of the packing bottom naturally provides a rough surface texture at the bottom edge where it contacts the flaps. This local roughness is sufficient to enhance gripping forces without requiring the entire surface to be processed, thus maintaining ease of manufacture while improving fixation reliability through increased friction at the critical contact points.
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 described packaging solution enhances the fixability of the packaging cover on the packing bottom, ensuring the safe transport of packaged articles by utilizing the rough surface of the leaf material and the encompassing flaps to create strong gripping forces.
Implementation Method 1
By means of the rough surface of the leaf material of the packing bottom, in interaction with the encompassing of the bottom edge by the flaps protruding inwardly... an improved fixing of the packaging cover on the packing bottom can be achieved, so that the article remains protected in particular during movement of the packaging. In particular, gripping forces formed by the encompassing, which are imparted via contact surfaces of the flaps and the inner side of the packaging cover on the packing bottom, can be supported by means of the increased roughness on the contact surfaces.

AI summary
The disclosure relates to a three-dimensionally shaped packing bottom of a leaf material of a plant, the packing bottom being adapted to receive an article to be packaged and comprising: a bottom support surface, a bottom side wall surrounding the bottom support surface, and a bottom edge arranged at an end of the bottom side wall, the end being distal with respect to the bottom support surface, wherein the bottom edge protrudes outwardly from the bottom side wall; and a packaging cover with inwardly protruding flaps. The packaging cover is arranged on the packaging bottom such that the flaps and an inner side of the packaging cover at least partially encompass the bottom edge, so that the packaging cover is fixed in its relative position with respect to the packaging bottom. Furthermore, a packaged article is provided.
