Definitions

• ABSTRACT Primary Examiner-Melvin D. Rein Attorney, Agent, or Firm-Price, Heneveld, Huizenga & Cooper 57] ABSTRACT The specification describes methods for preventing tobacco crumb formation in cigarette packages by heating the tobacco, cushioning it or providing for an electrostatic charge.
• the invention relates to a method for preventing the escape of tobacco crumb or detritus at the ends of cigarettes, more particularly in the case of cigarettes packed in transparent or translucent plastic foil.
• the invention is particularly concerned with such cigarettes packed individually.
• a further problem resides in that tobacco crumb must not be allowed to drop out of the structure of the cigarette filling owing to movement of the package, for example when the cigarette has already become somewhat dry.
• tobacco crumb should not arise when one or more cigarettes are removed from a package which has already been opened.
• One aim of the present invention is to prevent the escape of tobacco crumb or detritus from the ends of cigarettes, preferably cigarettes which are individually packed in transparent or translucent plastic foils, in a particularly simple manner without it being necessary to employ the above-described steaming operation which is somewhat difficult to operate.
• the present invention consists in a method for packaging cigarettes so as to prevent the escape of detritus from the ends of the cigarettes, in which the ends of the cigarettes before placing in a package are subjected to heating of short duration.
• the cigarettes are packed in transparent or translucent, that is to say light passing plastics foil and preferably the cigarettes are packed individually.
• the heating can for example be carried out with the help of microwaves so that there is a rapid baking operation which results in a coagulation of the proteins in the tobacco and the free ends of the cigarettes without the cigarette being deformed or singed. In this manner a type of self-sealing of the ciga rette is achieved without using added materials.
• the aim of the invention can be achieved by adopting the feature that the sealed package is subjected to friction in the zone receiving the tobacco ends of the cigarettes in order to produce an electrostatic high voltage charge.
• the method is so carried out that the packages are moved between rapidly rotating brushes after the sealing.
• electrostatic high voltage charge produced by friction leads to the tobacco surface of the cigarette being fixed in the package.
• Such electrostatic high voltage charges are effective for extraordinarily long periods of time and do not become dissipated even when the package is carried around for a long period of time in the pocket.
• the aim can also be achieved by adopting the feature that on laying the cigarettes at least at the tobacco ends in position a foam material cushion is laid additionally into the groove with the cigarette.
• This foam material cushion can in accordance with a further feature of the invention possibly be moistened.
• a method for preventing the emergence of tobacco particles from cigarettes to be packaged comprising the step of heating only the cigarette end to effect a rapid heating by microwave heating sufficiently to coagulate the proteins in the tobacco to seal the end thereof against the escape of detritus.
