Releasable Inner Liner for Reclosable Smoking Article Bundle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapped bundles of smoking articles lack effective protection from heat, moisture, and humidity after opening, and current packaging solutions are not cost-effective or simple in structure.
Innovation Solution
A wrapped bundle design featuring an inner liner with at least two sections that can be releasably attached to reclose the opening, using a pressure-sensitive adhesive applied in patterns to existing flaps, allowing for reattachment without additional labels or apertures, maintaining adhesion for multiple uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the top section of the inner liner is made removable with a perforation line to allow access to smoking articles, then ease of operation is improved, but the protective function against heat, moisture, and humidity deteriorates after opening
Solution Approach 1:
The patent applies the discarding and recovering principle by enabling the inner liner to be reclosed after opening. The releasably attaching means allow the opened sections to be reattached, recovering the protective function of the inner liner. This resolves the contradiction by allowing both easy access (through opening) and maintained protection (through reclosing), rather than permanently discarding the protective function after single use.
Solution Approach 2:
The patent applies the dynamics principle by making the inner liner configurable between open and closed states. The releasably attaching means enable dynamic transition between these states, allowing the inner liner to adapt its configuration based on usage needs. This resolves the contradiction by providing a dynamic system that can switch between ease of access and protective function, rather than being fixed in one state.
2Stability of the object's composition
If an inner frame is added to provide stability for the wrapped bundle with an aperture, then structural stability is improved, but device complexity and production cost increase
Solution Approach 1:
The patent applies the segmentation principle by dividing the inner liner into multiple sections that can be independently opened and reclosed. This segmentation eliminates the need for a rigid inner frame while maintaining structural integrity through the flexible segmented design. The sections work together to provide stability without requiring additional framing components, thus resolving the contradiction between stability and complexity.
Solution Approach 2:
The patent applies the parameter changes principle by transforming the inner liner from a rigid structured system (requiring inner frame) to a flexible system with variable configurations. The releasably attaching means enable the inner liner to change its structural parameters dynamically, providing stability when closed and accessibility when opened, eliminating the need for complex framing while maintaining structural integrity.
3Ease of manufacture
If the inner liner is designed as a conventional single-layer structure, then manufacturing simplicity is maintained, but protection from heat, moisture, and humidity is insufficient
Solution Approach 1:
The patent applies the composite materials principle by using a multi-layer inner liner structure with different material properties. The inner liner comprises layers with different characteristics (such as barrier properties, flexibility, and adhesion) that work together to provide enhanced protection against heat, moisture, and humidity. This composite structure maintains ease of manufacture by using standard lamination techniques while significantly improving protective function against harmful factors.

AI summary
A wrapped bundle comprises an inner liner wrapped about a predetermined collation of smoking articles. The inner liner comprises an inner liner outer edge and at least two sections defining an opening in the wrapped bundle. At least one section of the at least two sections is provided with an adhesive for releasably attaching the at least two sections to reclose the opening. The at least one section comprises a part of the inner liner outer edge.
