Hinge-Lid Container With Foldable Panels For Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge-lid containers for consumer goods, such as cigarette packs, have limited visible exterior surface area, making it difficult to display supplementary brand, advertising, or promotional information without modifying existing packaging machinery.
Innovation Solution
A hinge-lid container design that includes an integral first panel foldable outward from the box portion, revealing additional surface areas for printing or display, with optional second and third panels that can also be hinged outward, providing additional space for consumer information without altering the external appearance or dimensions of the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional hinge-lid containers are used, then the external appearance is simple and compact, but the visible exterior surface area is limited
Solution Approach 1:
The patent applies the dynamics principle by making the container wall panels movable rather than fixed. The first panel is hinged to the box portion and can be folded outward from its initial position, transforming the static container into a dynamic structure that reveals additional surface areas when opened, thereby increasing the visible exterior surface area without permanently altering the compact form.
Solution Approach 2:
The patent implements another dimension by adding panels that can be folded outward from the container wall, effectively utilizing the third dimension (depth/space outside the container) to create additional display surfaces. The first panel folds outward to reveal a second panel, and potentially a third panel, creating multiple layers of display area that extend beyond the original container boundaries.
2Area of stationary object
If additional surface areas are added to display information, then consumer information display capability is improved, but the production process requires machinery modification
Solution Approach 1:
The patent applies universality by designing the additional panels to be integrated into the existing container structure using the same manufacturing process. The first, second, and third panels are all formed from the same blank material and assembled through the same folding and joining operations as the original container walls, allowing the structure to serve both its original containment function and the new information display function without requiring separate production lines or machinery modifications.
3Area of stationary object
If panels are hinged outward to increase display area, then additional surface area is exposed, but the container structure becomes more complex
Solution Approach 1:
The patent applies merging by combining the additional display panels with the existing container wall structure. The first panel is hinged to the box portion at the same location where the original wall would be, and the second and third panels are similarly integrated into the wall structure. This merging approach allows the panels to function as both structural elements and display surfaces, reducing the perceived complexity by unifying the display mechanism with the container structure rather than adding separate mechanical components.

AI summary
A hinge-lid container includes a box portion and a lid portion hinged to the box portion. The box portion includes an integral first panel connected to the remainder of the container along a first hinge line and an integral second panel. The first panel in an initial position forms at least part of a wall of the box portion and the second panel in an initial position underlies the first panel. The first panel is defined in the wall of the box portion by at least one line of weakness in the initial position and is foldable about the first hinge line from the initial position to a second position in which it is hinged outwardly from the remainder of the container. The second panel is connected to the remainder of the container along a second hinge line. The box portion can include an integral third panel.
