Folding Box With Pivotable Front Wall And Push-In Lip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding boxes for cakes are complex to open and close, and users often struggle to understand how to open the front side, leading to potential damage to the cake during extraction.
Innovation Solution
A folding box design featuring a pivotable front wall with a push-in lip that engages with an opening in the lid panel, allowing easy opening and closing without additional fastening, and rounded fixing flaps for simplified folding and visibility of the front wall for easy closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front wall is connected to side walls by tear-off lips as in EP 2 295 330, then the cake can be extracted easily, but the box becomes too complex for users to understand how to open
Solution Approach 1:
The invention extracts the opening function from a complex multi-component mechanism and concentrates it into a single integrated push-in lip on the front wall. This lip is designed to push through the sealing flap when pressed, automatically opening the box without requiring users to understand complex tearing or folding sequences.
Solution Approach 2:
The push-in lip mechanism is designed to be self-operating - when the user presses the lip, it automatically pushes through the sealing flap and opens the box without requiring additional manual actions or understanding of complex mechanisms. The system serves itself by converting simple pressing motion into effective opening action.
2Reliability
If many manual actions are required to erect the box as in EP 0 274 982, then the box can be closed securely, but opening and closing becomes awkward
Solution Approach 1:
The push-in lip is pre-positioned on the front wall in a ready state. When the user needs to open the box, the lip is already in place to perform the opening action immediately upon pressing, eliminating the need for multiple preparatory manual actions required in previous designs.
3Reliability
If adhesive tapes or ribbons are used to keep the lid closed, then the lid can be secured, but the box becomes more complex and requires additional materials
Solution Approach 1:
The invention extracts the closure function from external adhesive tapes or ribbons and integrates it into the box structure itself through the push-in lip mechanism. The lip forms an inherent part of the front wall and provides closure security without requiring any additional external materials.
Solution Approach 2:
The push-in lip serves multiple functions: it acts as a structural element of the front wall, provides the opening mechanism when pressed, and serves as the closure security feature when in its resting position. This multi-functionality eliminates the need for separate adhesive tapes or ribbons.
