Description

- 1 Title: Nicotine level reduction in cigarettes The invention relates to

the reduction of the nicotine levels in cigarettes and the like.

2209655 It is generally understood that nicotine contained in cigarettes is injurous to the human body, so in the past filter tins or cigarette holders were invented to prevent the injury of nicotine, to prevent a part o the nicotine content from entering the body.

Furthermore, those who used filters in cigarette holder all know, whenever the filter ti,p is full ot nicotine inside, it must be replaced b,,, a new one, inconvenient, broken, or a will produce disclosed in and wnenever tne packet of cigarettes is being mildewed. this specification is intended disadvantages mentioned above.

a bad smell of Which L's rea'L!,,, verv )ackinQ of cigarettes is opened too lona, it So the device to solve the two The invention provides a method of reducing the nicotine level in cigarettes or the like comprising the steps of procuring a container, fitting the container with Bakuhan stone and inserting the filled container within a packet of cirgarettes or the like.

Preferably the container may be perforated.

1 Advantageously, the container may be of a size and shape comparable with the cigarettes or the like within the packet.

There will now be described with reference to the accompanying drawings an example of a filled container accordina to the invention. It will be understood that the description is given b,,, way of limitation.

In the drawings:- Figure 1 shows a perspective view of a cigarette packet containinQ a device used according to the invention; Figure 2 is a longitudinal section through the device of Figure 1; Figure 3 is a perspective view of a device for use in the -method of the inventions; and Figure 4 is an exploded view of the device.

Figure 1 shows a device 2 protruding from a cigarette packet 1. The device is filled with Bakuhan stone granules 4.

The device 2 comprises a body 5 and a cap 6. The body 5 is filled through its mouth 7 and is provided with elongate 3 slots 8 in its cylindrical wall and an aperture 9 in its end wall.

Bakuhan stone is a magnet metal stone.

The present invention discloses that Bakuhan stone has the effect of rendering cigarettes moisture-proof, mildew-proof, and of the decomposition of nicotine. The function of decomposing nicotine denotes the ion reaction produced by Bakuhan stone (4) to decompose nicotine. To insert the device (2) in the cigarette pack (1) requires 10 minutes or so to develop the effect, and the result is that not only the injury of nicotine is eliminated, bUt also the unique pungent taste contained in the original nicotine of the cigarette is eliminated, so that the clqarette is smoked inore olp-asan7-l,,,,.

In addition, Bakuhan stone (4) possesses the f,-incr-ion of absorption, so, besides absorbin,g the moisture in the air, the alcohol in the wine, or the chlorine and impure material (miscellaneous substance) in the water may also be absorbed After Bakuhan Figure 4, it i (5) is closed product.

stone (4) is granulated to the size as in s filled into the body (5), and after the body with the cap (6), then it becomes the finished But Bakuhan stone (4) in the finished product must be treated so that the Bakuhan stone will never fall out of the body (or the holes of various shapes) or the round hole (a) on the end wall (various hole shapes).

From the applied example mentioned above, it may be clearly understood that merely to put Bakuhan stone (4) into the inner par t of nicotine decomposition moisture-proolll"' body device (2), it then becomes the finished product, and if the main bodv is made from plastics, the outer shape may simply be changed (of course high-class material sucl.h as gold or copper or other inetal material may also be used). Thus to design as long cylinder shape to use in the cigarette pack is very convenient.

Furthermore, besides the device (2) 'formed as the body (5) described above Eilled with Bakulian stone (4) a wider container of better ventilation or cylinder plate shape, or other shape 'filled with Bakuhan stone may be also utilised, and to cut Bakuhan stone into stone pieces may also be applicable.

From this, it may be understood that the chief purpose of this creation is to offer the device, in which the Bakuhan stone, developing its function of moisture-proof and nicotine decomposition (in the cigarette pack), makes the disadvantages of the original filter tip for inconvenience of carriage and necessity of replacement, etc., completely 1 eliminated, further developing the effect of moisture proof which the filter tip cannot.

The following experimental results are given by way of example only to illustrate the property of Bakuhan stone:

Sample: BAKUHAN STONE 2. Purpose of the test: To examine the inf luence of the sa:r,,-.le on nicotine in an aqueous solution.

Outline of the iest The sample was put in to a nicotine aqueous solution. After 15, 30 anci 60 winutes, nicotine concentrations of the solution were- deter-mined respectively by gas-liquid chro-rnatograr).,, and eacl) value was com,3ared with t}at deter-mined prior to the addition of the sample.

Results: The results are shown in Table-1. The percentage of nicotine concentration at each time to that determined prior to the addition of the sample is also given in Table-1.

6 Table-1 Change of nicotine concentration Time (min) before is 30 60 addition nicotine concentration 0.992 0.997 0.935 0.943 (mg/1,11) Percentage of nicotine concentration(%) 101 94.2 95.0 Time after addition of the sample Methods: 1) Procedure About 10 9 of the sample was put in to 50 ml aqueous solution containing 1 mg/ml nicotine and allowed to stand until determination was made. For determination of nicotine, 0.5 -ml aliquot of the sample and 1 ml internal solution were pipetted into a 5 inl volumetri flask and diluted to volume with methanol and then subjected to gas-liquid chromatography.
