Packaging Box Flap Protrusions for Secure Secondary Article Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging members lack an efficient mechanism to retain and protect additional articles within the packaging box without increasing component count, leading to potential accidental release during unpacking.
Innovation Solution
The packaging member incorporates an upper buffer member with a housing region and inner flaps featuring protrusions that retain the additional article, reducing the need for separate retaining members and enhancing protection and ease of unpacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a buffer member is arranged outside the housing region to protect the article, then impact protection is improved, but the packaging box structure becomes more complex and requires additional retaining mechanisms
Solution Approach 1:
The patent merges the buffer member and housing region into a single integrated upper buffer member structure. The housing region is formed as an integral part of the buffer member, eliminating the need for separate retaining mechanisms and reducing structural complexity while maintaining impact protection functionality.
Solution Approach 2:
The upper buffer member performs multiple functions simultaneously: it provides impact protection for the article, houses the additional article through its housing region, and retains the additional article through the protrusion mechanism. This multi-functionality reduces the need for separate components.
2Reliability
If separate retaining members are used to hold additional articles, then retention reliability is improved, but component count and manufacturing cost increase
Solution Approach 1:
The retaining function is merged into the inner flap structure through the protrusion feature. The protrusion is formed as an integral part of the inner flap, combining the retention function with the existing flap component rather than adding a separate retaining member.
Solution Approach 2:
The inner flap with its protrusion features provides self-retention functionality. The protrusion automatically engages with the additional article to prevent accidental release during unpacking, without requiring external retaining mechanisms or additional components.
3Ease of operation
If the opening is closed with only outer flaps, then ease of operation is improved, but additional articles cannot be securely retained
Solution Approach 1:
The flap structure is segmented into outer flaps and inner flaps with different functions. The outer flaps provide the primary closing function for ease of operation, while the inner flaps with protrusions provide the retention function for additional articles. This segmentation allows each component to specialize in its function.
Solution Approach 2:
The retention function is added in a new dimensional layer by introducing inner flaps beneath the outer flaps. This layered structure allows the outer flaps to maintain their simple closing function while the inner flaps provide the additional retention capability through their protrusions.

AI summary
A packaging member includes a packaging box and an upper buffer member. The upper buffer member is arranged above a first article to be packaged and adjacently to an opening of the packaging box and internally includes a housing region for housing a second article to be packaged. The packaging box includes an outer flap, an inner flap, and a protrusion. The protrusion is provided on the inner flap and protrudes, when the opening is closed by the outer flap, toward the housing region in the upper buffer member so as to contact the second article to be packaged.
