II.6. Matches

Three types of paper type have been used for sample matches’ production i.e. wood cardboard, common cardboard and woodfree cardboard, cellulose type.  All types of the utilized paper are characterized in extended stiffness and durability against bending and creasing. The paper type used is app. 1mm thick for user functionality purposes i.e. trouble-free match detachment from the match row, easy and safe hold and bending resistance. The breadth of app. 1mm enables matches’ location in the additional storage space, cumulating one-sided lateral sulfur overhang (app. 0,5 mm) into an arrangement of the match rows.  Other substances, e.g. wood, were of no use because they did not match the box design and seemed distinct from the rest of the box.  Each paper type offers different characteristics, i.e.: combustion rate, self-extinguishing rate and the intensity of the odor. The maximum match size in proportion to available space of the additional storage recess has been utilized.   
The matches are similar to traditional hitherto existing safety matches in terms of volume and functionality. Standard safety matches are compliant with the requirements specified in the European regulations EN 1743 and are environment and user-friendly. Said parameters also apply to the sulfur type and the match striking surface.   
The rows of matches are cut out scraplessly and the match heads are also based on sinusoidal pattern for improved break resistance after the sulfur application. The sinusoidal match heads were used for the application of condensed sulfur pulp and for optimal use of limited additional storage space so as to contain defined number of matches i.e. 22 matches for 20 cigarettes. The remaining 2 matches in the row are glue-bonded to the box and are treated as a reserve. The dimensions of the matches can be decreased in the mass production process taking in to consideration mainly functionality. There are three bridge connectors which join the matches in their bottom sections ( app. 0,5 mm wide and 0, 20mm deep). 
It was impossible, though, to achieve mechanical perfection of the sample match rows and therefore some matches break off too easily and the number of bridges might seems insufficient. For better safety it is advisable to use 4 bridges. The drawing discloses actual dimensions of the punching die and produced matches. In mass production and fastening in the box it is important to notice that the matches be arranged conversely, in single rows, so that the conjoining bridges be situated at the bottom as only such position guarantees safe and trouble-free use of the matches while the matches’ front panel becomes smooth enough for commercial printing.  
Paper matches are nicer in touch and cheaper in production than their traditional standard counterparts while they enable additional commercial printing and appropriate configuration.  
The matches are also paraffin imbibed in compliance with the European norm EN 1743, to achieve double combustion rate while giving lesser and softer flame than the standard matches.
