Solution Overview

Problem

Cigarette packs with sealed blocks require an effective aroma and moisture-proof opening aid that is also easy to open and close multiple times, with the grip tab becoming difficult to grasp after repeated use.

Innovation Solution

The pack features elevations on the inner collar's front wall, which protrude outward and are embossed onto the sealing block, creating detectable projections for easier gripping of the grip tab, and the grip tab is positioned to be lifted by the lid when opened, facilitating repeated use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a sealing block with adhesive-fixed opening tab is used, then aroma and moisture protection is improved, but the grip tab becomes difficult to grasp after repeated use

Engineering Contradiction:
Improvearoma and moisture protectionVSAvoidgrip tab accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The closure label is segmented into a collar portion and a grip tab portion. The collar remains attached to the sealing block while the grip tab can be repeatedly grasped and pulled away, allowing the sealing function to be maintained while providing easy opening access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The grip tab acts as an intermediary element between the user and the adhesive-sealed closure label. It provides a non-adhesive gripping surface that transfers the pulling force to open the seal without compromising the aromatic and moisture-proof sealing block.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If elevations are embossed on the collar, then grip tab detectability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvegrip tab detectabilityVSAvoidcollar fabrication
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The collar surface parameters are changed by embossing elevations that create detectable topographical features. These elevations modify the surface geometry to provide tactile cues for grip tab location without requiring complex additional components.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Elevations are formed by deforming the collar material into curved or rounded protrusions through embossing. These curved features are more easily detected by touch and provide better gripping surfaces compared to flat or sharp edges.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

The invention relates to (cigarette) packs having an inner pack (27) in the form of a sealing pack, wherein said packs comprise a closure tab (23) in the area of a removal opening (22). The closure tab (23), which is fixed by gluing, can be gripped using an adhesive-free gripping tab (26). In order to improve the presentation of the gripping tab (26), a projection is provided in the area of the gripping tab on the inner pack or on a collar, such that at least one tab rim (32) of the gripping tab (26) is exposed for gripping. In addition, support edges can be provided in the area of the inner side of a cover front wall (15), which support edges deform the gripping tab (26) during the opening of the cover (11).
