Cigarette Pack Collar Embossing for Block Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cigarette packs struggle to accommodate cigarette blocks of varying dimensions due to the low material rigidity of standard collars, leading to instability and play within the receiving space.
Innovation Solution
The collar features dome-like organs formed by material deformation, such as embossing, which reduce the cross-section of the box part to match the dimensions of the cigarette block, providing stable support and secure fit through protrusions on both sides and attachment to the box part walls with glue, ensuring the cigarette block is held firmly during packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard cuts for collars are used, then the collar can be easily manufactured, but the material rigidity is relatively low causing tabs to lose support function after short time
Solution Approach 1:
The invention changes the physical state of the collar material by applying heat and pressure to transform it from a soft, flexible state to a hardened, rigid state. This parameter change in material rigidity allows the collar to maintain its support function for extended periods while still being manufacturable through standard processes
Solution Approach 2:
The invention creates a composite structure where the collar combines two material states: the base material remains relatively soft for manufacturability, while the embossed tabs are transformed into a hardened composite with enhanced rigidity. This composite approach allows different parts of the same component to have different mechanical properties suited to their specific functions
2Adaptability or versatility
If the cross section of the box part is reduced to accommodate different cigarette block dimensions, then the receiving space can be adapted, but the collar material rigidity must be increased to maintain support
Solution Approach 1:
The invention applies parameter changes locally to the collar tabs through embossing, which transforms the material from soft to hard state. This localized parameter change enables the collar to provide sufficient support strength for adapted receiving spaces without requiring the entire collar to be made from high-rigidity material, thus maintaining adaptability
3Shape
If embossed lettering is used to reduce the cross section, then the appearance can be modified, but the receiving space cannot be effectively adjusted
Solution Approach 1:
The invention uses embossed tabs with curved, dome-like shapes that protrude into the receiving space. These three-dimensional curved structures effectively reduce the cross-sectional dimensions of the receiving space to match different cigarette block sizes, providing genuine adaptability rather than just superficial shape modification
Solution Approach 2:
The embossed tabs are pre-formed during collar manufacturing to create the reduced cross-section geometry. This preliminary action ensures the receiving space is pre-adapted to specific cigarette block dimensions before the collar is assembled into the box, enabling effective space adjustment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively adapts the receiving space to accommodate cigarette blocks of different sizes with minimal play, maintaining stability and preventing slipping, while the embossed curvatures and glue points ensure secure positioning and support.
Implementation Method 1
the collar has dome-like organs formed by material deformation, in particular by embossing
Implementation Method 2
the collar is attached to walls of the box part by means of glue
Implementation Method 3
the cigarette block is connected to the box part during the packaging process by means of a glue point, preferably made of hot glue

AI summary
The invention relates to a packaging for cigarettes (26) comprising a box part (11) and a cover (12) which is pivotably arranged on the box part (11), the box part (11) forming a receiving chamber for a cigarette block (25), and a collar (13) being arranged in the box part (11), which collar protrudes from the top-open box part (11) and is enclosed by the cover when the cover (12) is in closed position, the collar (13) having means for reducing the size of the receiving chamber, in particular of the cross-section, of the box part (11). The invention is characterised in that the collar (13) has elements (31, 32) formed by material deformation, in particular embossment, in order to reduce the size of the receiving chamber, in particular of the cross-section, of the box part (11) according to the dimensions of the cigarette block (25).
