Hinged Lid Container Single-Sided Printing via Segmented Blank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide and shell containers require double-sided printing to achieve printing on all external surfaces, which is costly and time-consuming, and do not allow for efficient use of a single-sided blank.
Innovation Solution
A slide and shell container design where the inner slide is formed from a single laminar blank with a hinged lid, allowing the lid flap to engage with the outer shell, enabling the container to be opened without direct connection between the lid back and top walls, thus allowing printing on only one side of the blank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the lid back wall is directly connected to the lid top wall, then the structural stability is improved, but the blank must be printed on both sides to achieve printing on all external surfaces
Solution Approach 1:
The lid back wall is divided into two separate panels that are not directly connected to each other. These panels are connected to the lid top wall through side walls, creating a segmented structure that allows the blank to be printed on one side only while still achieving complete external surface coverage when assembled.
Solution Approach 2:
The connection between lid walls is achieved through a third dimension by introducing side walls that connect the back wall panels to the top wall. This dimensional approach allows all external surfaces to be printed from a single-sided blank without requiring direct back-to-top wall connection.
2Ease of operation
If the lid is directly connected to the box, then the structural stability is improved, but the lid cannot be opened by engagement with the outer shell
Solution Approach 1:
The lid is extracted from direct connection to the box and instead connected through a hinge mechanism. This allows the lid to be pivoted open when engaged with the outer shell, while the box remains stably connected to the slide structure.
Solution Approach 2:
A hinge is introduced as an intermediary element between the lid and the box. This hinge allows the lid to pivot relative to the box when engaged with the outer shell, enabling easy opening while maintaining the structural integrity of the box-lid assembly.
3Manufacturing precision
If double-sided printing is used on the blank, then printing on all external surfaces is achieved, but production cost and time increase
Solution Approach 1:
The blank structure is segmented such that all external surfaces to be printed are located on one side of the blank. The lid back wall is divided into separate panels connected through side walls, allowing single-sided printing to cover all external surfaces when the container is assembled.
Solution Approach 2:
The printing surface is extended to all external faces by utilizing the three-dimensional assembled structure. A single-sided blank is folded and connected through fold lines to create multiple external surfaces, all printable from one side before assembly.

AI summary
A slide and shell container for consumer goods includes an outer shell and an inner slide. The inner slide includes a box and a lid, which is hingedly connected to the box at a hinge. The inner slide is slidable within the outer shell between a closed position in which the lid is closed and an open position in which the lid is open. The lid includes a lid flap which is arranged between the inner slide and the outer shell such that an engagement of the lid flap and the outer shell is capable of opening the lid. The lid flap is capable of engaging with the outer shell during movement of the inner slide from the closed position to the open position. The lid also includes a top wall, a back wall, a first side wall and a second side wall. The first side wall is connected through a fold line to the back wall and is connected through a fold line to the top wall.
