Definitions

  • the present invention relates to a method and a device of manufacturing a packaging comprising loose tobacco.
  • the provision of loose tobacco is an alternative to buying cigarette packages for roll your own applications.
  • the tobacco for such applications is packed in individual packagings from which the user can take them and roll a cigarette using a suitable cigarette paper.
  • a point of interest in producing loose tobacco packagings is to achieve different flavors in the loose tobacco.
  • several options are available, e.g. the addition of flavors and/or the addition of additives that react with the tobacco to obtain a certain flavor.
  • flavoring is carried out by introducing the flavor and/or additive into loose tobacco in a processing cylinder and allowing time for the flavor to blend into the tobacco. Once the flavor is blended, the flavored tobacco material is packed in a known manner.
  • US 2015/013693 A1 discloses a device for flavoring a smoking article via diffusion, wherein filter rods are flavored.
  • US 2008/210249 relates to systems, devices and methods wherein porous plastic articles are used for delivering one or more additives to a smokeless tobacco product, wherein an additive is added in a dispensing article.

  • the volatile compound for flavoring the loose tobacco material is volatile, i.e. has a high vapor pressure at ordinary room temperature of between 20 and 25°C at normal pressure of 101.325 kPa. The high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate from the volatile compound for flavoring the loose tobacco material.

  • the amount of volatile compound for flavoring the loose tobacco material, particularly alcohol can be kept quite low as losses can be avoided by introducing the volatile compound for flavoring the loose tobacco material, particularly alcohol, into the packaging. As the volatile compound for flavoring the loose tobacco material, particularly alcohol, is introduced essentially into the packaging, it can react with the loose tobacco material during storage.
  • additives for setting a suitable pH like an acid, polyols for controlling the ester reaction, etc.
  • further additives are not particularly restricted, and can e.g. comprise flavors that can usually be added to tobacco products, e.g. ester components, etc., that are not volatile compounds for flavoring the loose tobacco material.
  • the addition of water (humidification) to the loose tobacco material during the packaging process is not preferred as it can inhibit the production of the ester flavor components. However, it is not excluded that water is added to achieve a suitable moisture of the loose tobacco material.
  • Further additives and their amounts can be e.g. taken from EP 2 798 966 Al, the contents of which are included herein by reference with regard to further additives.

  • 5 corresponds to the one shown in FIG. 4, except that the unit for inserting loose tobacco material 120 and the unit for introducing at least a volatile compound for flavoring the loose tobacco material, particularly an alcohol 130, with the pipe 31 switched places.
  • a pouch comprising loose tobacco material and ethanol is produced by first portioning and introducing 30 g of loose tobacco material into an empty pouch made of a plastic material comprising PE and PET having dimensions of a width with of 145 mm, a length of 110 mm, and a lip of 115 mm, followed by dripping ethanol into the pouch in an amount of 3 wt.%, based on the weight of the loose tobacco. After the dripping, the pouch is sealed. The loose tobacco material is dosed with a funnel, compressed, and inserted into the pouch. After the introduction of the loose tobacco material and the ethanol the pouch is sealed with heat sealing, the flap of the pouch is closed and a closure tape is applied to the pouch. The filled pouch is aged in a storage area for 48 h at 50°C and then ready for consumption.
  • a pouch comprising loose tobacco material and ethanol is produced by dripping ethanol into an empty pouch as described in Example 1, followed by inserting 30 g of loose tobacco into the pouch in such a manner that the amount of ethanol is 3 wt.%, based on the weight of the loose tobacco. Afterwards the pouch is sealed and further processed as described in Example 1. Comparative Example 1
  • Example 1 30 g of loose tobacco material was sprayed in a cylinder with 3 wt.% ethanol, based on the weight of the loose tobacco. Afterwards the tobacco is introduced into a pouch as described in Example 1, and the pouch is sealed and further processed as described in Example 1.
  • Example 2 Two other pouches as described in Example 1 were filled with 30 g of loose tobacco but this time without any introduction of ethanol to serve as control references. The pouches were sealed and further processed as described in Example 1. Control Reference 1 was stored for 48 h at room temperature, while Control Reference 2 was stored for 48 h at 50°C.
  • FIG. 6 shows an ester analysis of the loose tobacco contained in the five different pouches of Example 1 (EX1), Example 2 (EX2), Comparative Example 1 (CE1), Control Reference 1 (CR1) and Control Reference 2 (CR2) obtained by solid phase microextraction followed by gas chromatography.
  • the x-axis represents the residence time t in seconds and the y-axis represents signal intensity.
  • Each peak represents a compound present in a sample and its amount in the sample is directly proportional to the area below each peak.
  • Example 2 the spectrum of Control Reference 1 and Control Reference 2 is identical, and all the compounds that were identified for these samples are also visible in the other samples in an almost identical amount.
  • Example 1 Example 2 and Comparative Example 1 additional compounds are identified at the beginning of the spectrum.
  • the first peak corresponds to ethyl acetate, which is the desired flavor compound generated from the reaction of tobacco and ethanol.
  • Comparative Example 1 are comparable.
  • the second peak (numeral 62 in FIG. 6) in Example 1, Example 2 and Comparative Example 1 corresponds to ethanol and this shows the amount of ethanol that neither evaporated nor reacted with the loose tobacco.
  • the amount of ethanol present in Comparative Example 1 is significantly lower than the amount of ethanol present in Example 1 and Example 2. Since the amount of ethanol that was dosed into the loose tobacco was the same for the samples of Example 1, Example 2 and Comparative Example 1, and the amount of ethyl acetate is also substantially the same in them, the difference in ethanol between the samples must come from evaporation of ethanol between dosing the ethanol into the loose tobacco material, inserting it into the packaging and closing the packaging.
  • the inventors discovered that the present method can save at least 50% of the amount of ethanol required, with further savings expected by adjusting the amount of ethanol dosed into the packaging so that the ethanol peak almost disappears from the ester analysis. The inventors expect that this would occur with an amount of ethanol comprised between 1 and 2 wt.%, based on the weight of the loose tobacco.
