Inner Frame Perforation for Hinge Lid Pack Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hinge lid packs for consumer goods, such as cigarettes, face issues with prolonged exposure to air or moisture, leading to damage and loss of contents, as existing packaging does not effectively prevent ingress or egress of air, moisture, or odors during storage.
Innovation Solution
A method and structure for manufacturing hinge lid packs that includes an inner frame with a perforation line in the front panel, allowing side panels to fold inward and create an inner cavity, enhancing containment and rigidity, and using glue dots for assembly, which can be modified post-construction to adjust the inner frame's position and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inner frame with perforation line is added to create an inner cavity, then containment effectiveness and rigidity are improved, but device complexity increases
Solution Approach 1:
The inner frame is divided into separate panels (front panel, side panels, back panel) connected by perforation lines, allowing the structure to be segmented and folded into an inner cavity. This segmentation provides the necessary containment effectiveness while maintaining manufacturing simplicity through modular assembly.
Solution Approach 2:
The inner frame structure is nested within the existing box and lid structure of the hinge lid pack. The inner cavity formed by the folded panels creates a nested containment system that enhances reliability without requiring a completely separate outer structure.
2Loss of substance
If the inner frame structure is added to contain loose tobacco, then loss of substance is reduced, but manufacturing complexity increases
Solution Approach 1:
The inner frame is pre-formed with perforation lines and fold lines during the manufacturing process, allowing it to be quickly assembled and folded into the final cavity structure. This preliminary preparation reduces the complexity of the assembly process while effectively preventing tobacco loss.
Solution Approach 2:
The inner frame utilizes thin panel structures that can be folded and formed into a rigid cavity when assembled. This approach creates an effective containment structure from minimal material, reducing manufacturing complexity while preventing substance loss.
3Strength
If the inner frame is made rigid to maintain structure, then strength is improved, but adaptability decreases
Solution Approach 1:
The inner frame incorporates perforation lines that allow controlled flexibility and movement during assembly, enabling the structure to be adapted after construction. The rigid panels provide structural strength while the perforated connections allow for post-construction modifications such as removing items like lighters.

AI summary
A method of manufacturing a hinge lid pack for containing loose elongated smoking articles is disclosed, the method includes forming a box and a lid connected to the box about a hinge line extending across a back wall of the pack. The box can include a front wall, a left side wall, a right side wall, a back wall, and a bottom wall, and the lid can include a lid top wall, a lid left side wall, a lid right side wall, and a lid back wall. A perforation line is formed in a front panel of an inner frame, the inner frame including the front panel, a right side panel, and a left side panel, and at least a portion of the inner frame is glued to the front wall of the box of the hinge lid pack.
