Description

The present invention provides a cooling element for use with smoking products such as cigarette heated products, non-combustion heated products and the like.

Tobacco heated products or non-combustion heated (HNB) products are well known. The idea of a tobacco heating product is that the tobacco is heated to a specific temperature (such as 350 ° C) without burning. It sends steam containing nicotine, but it is believed that heating without burning prevents the production of combustion products that are harmful to consumers.

Tobacco heating products (HNB products) can include improved tobacco plugs and other mouthpiece elements wrapped in paper plug packaging to give a tobacco-like appearance. In one such product, a reconstituted tobacco plug, a hollow wrapping acetate tube, a PLA [polylactic acid] wrapping plug, and a conventional wrapping acetylate segment are wrapped in white paper. The product can then be inserted into a heating element that heats the cigarette, and the product can then be "smoked" by the consumer. The function of the "filter" in these products is very different from the cigarette filter, the main function is to provide the look and feel of the cigarette and to cool the smoke to a temperature acceptable to the consumer. In the above products, it is the PLA section that performs an important cooling function.

Hereinafter, the cooling element of the present invention shown in FIGS. 1 and 1 (FIG. 1) showing a cross section in the long axis direction of the tobacco heating product according to the present invention provided with the cooling element according to the present invention (not at a constant scale). It can be used in the tobacco heating product according to the present invention shown in FIGS. 2 and 1 (not at a constant scale) showing an axial cross section (along the line XX), which is also the one of the present invention. FIG. 3 (not at a constant scale) showing an axial cross section (along line XX of FIG. 1) of a cooling element different from FIG. 2, and the cooling elements (B, C, D, E) of the present invention. The present invention will be considered in more detail with reference to FIG. 4, which compares the pressure drop (mmWG) of the conventional PLA cooling element (A).

FIG. 1 shows a long axis cross section along the center line of the columnar HNB product 1. The columnar HNB product 1 comprises four segments: a columnar plug 2 for reconstituted tobacco, a columnar hollow acetate tube 3, a cooling element 4, and a columnar plug 5 for cellulose acetate tow.

The plug 2 of the reconstructed cigarette 2 has a length of 12 mm and an outer circumference of 23.2 mm, and forms one end of the HNB product 1. Such plugs are well known in the art. This plug is heated by a heating device during use, as is well known in the art. One end of the reconstructed tobacco material plug 2 abuts on a 7 mm long cylindrical hollow acetylate tube 3 having an outer circumference of 23.2 mm and a wall thickness of 1.3 mm. The tube 3 has a columnar hole 3a. The end of the cylindrical hollow acetate tube 3 opposite to the plug 2 abuts on the cooling element 4. Hollow acetate tubes and their manufacture are well known in the art of tobacco smoke filters (see, eg, GB970817, eg, embodiments of FIG. 7 and related considerations).

The cooling element 4 comprises a tubular core extending in the longitudinal direction of the thermoformed cellulose acetate material having a length of 18 mm. The tubular core extending in the longitudinal direction of the cellulose acetate material extends over the entire length of the tubular core and the inner surface defining the hole (or hole) 8 having a diameter of 2 mm extending in the longitudinal direction over the entire length of the tubular core. It is thermoformed with a profile outer surface containing five channels or grooves 9 extending along the major axis of a generally shallow U-shaped cross section with a maximum depth of 1.80 mm and a width of 1.5 mm. The five channels 9 are equidistant around the outer surface of the profile (as can be seen from FIG. 2). The longitudinally extending tubular core of the cellulose acetate material has a uniform axial cross section, as shown in FIG. It should be understood that the cross section of the cooling element 4 is considered to be substantially annular with five shallow U-grooves or channels 9 equidistant around it. The term "peripheral", when used in connection with a grooved / channeled cooling element, refers to a circular imaginary line that passes around the outer (circular) portion of the cooling element but ignores the channel. Therefore, the outer circumference of the element is approximately 23.2 mm so as to substantially coincide with the outer surface of the hollow acetate tube 3 with which it abuts (has a similar outer circumference). The cooling element 4 is thermoformed by a steam coupling process, as is well known in the art. Cellulose acetate tow is then fed into a steam die that has an introduction but is tapered to the size and shape of the required cross section (eg, the cross section shown in FIG. 2). As the tow passes through the die, it is molded and partially cured to form the required shape. There may be more than one steam die, followed by several drying sections that send hot air to the rods to remove excess steam / moisture. The rod is then fed onto the orthotic device, where it is withdrawn and cut to the desired length.

The columnar plug 5 has a length of 8 mm and an outer circumference of 23.2 mm, and includes a rod of cellulose acetate tow with a plug package arranged around it. These "packaging settate" plugs are well known in the art of cigarette smoke filters. The plug 5 abuts on the end of the cooling element 4 opposite to the hollow acetate tube 3 so that the cooling element 4 is between the plug 5 and the hollow acetate tube 3.

The reconstructed tobacco columnar plug 2, columnar hollow acetate tube 3, cooling element 4, and cellulose acetate tow columnar plug 5 surround the plug 2, tube 3, element 4 and plug 5 and resemble a cigarette. It is further packaged in a plug wrapping (not shown) of conventional plug wrapping paper (well known in the art) that gives a good appearance.

The diameter of the hole 3a (sometimes referred to herein as dimension "A") is such that a portion of the hole 3a of the tubular element 3 coincides with a hole 8 of the cooling element (eg, a portion thereof) of the tubular element. A portion of the hole is large enough to coincide with at least a portion (ie, the bottom edge) of each groove (channel) 9. Therefore, it should be understood that the outer groove or channel 9 of the cooling element 4, as well as the central hole 8, partially overlaps the wider hole 3a of the hollow acetate tube 3. During use, hot steam from the tobacco plug (heated in the conventional way) is sucked into the hole 8 and channel 9 of the cooling element 4 through the hole 3a of the hollow acetylate tube 3 and then to the final acetylate plug. It is sucked into 5 and passed through it into the smoker's mouth. This suction of hot steam through both the holes 8 and the channels 9 of the cooling element 4 is believed to provide sufficient cooling, an effect not expected from the cellulose acetate material.

It should be understood that hollow acetate tubes, packaging settate segments and cooling elements can be manufactured by methods well known in the art.

FIG. 3 shows the axial direction (along line XX of FIG. 1) of different cooling elements 40', which is also of the present invention, which can be used in the tobacco heating product according to the present invention shown in FIG. Shows cross section (not constant scale). It should be understood that the heating element 40'can be used in place of the element 4 in the tobacco heating product according to the present invention shown in FIG.

The cooling element 40'includes a core extending along the major axis of the thermoformed cellulose acetate material having a length of 18 mm. The longitudinally extending core of the cellulose acetate material consists of five longitudinally extending cores of a generally shallow U-shaped cross section with a maximum depth of 1.80 mm and a width of 1.5 mm extending over the entire length of the core. Alternatively, it is thermoformed together with the profile outer surface including the groove 90'. The five channels 90'are equidistant around the outer surface of the profile (as can be seen from FIG. 3). The longitudinally extending core of the cellulose acetate material has a uniform axial cross section, as shown in FIG. It should be understood that the cross section of the cooling element 40'is considered to be substantially circular with five shallow U-grooves or channels 90' dislocated equidistantly around it. The term "peripheral", when used in connection with a grooved / channeled cooling element, refers to a circular imaginary line that passes around the outer (circular) portion of the cooling element but ignores the channel. Therefore, the outer circumference of the element 40'is the hollow acetate tube 3 shown in FIG. 1 with which it abuts (has a similar outer circumference) when the cooling element 40'is used in place of the cooling element 4 of FIG. It is about 23.2 mm so as to almost match the outer surface. The cooling element 40'is thermoformed by a steam coupling process, as is well known in the art. Cellulose acetate tow is then fed into a steam die that has an introduction but is tapered to the size and shape of the required cross section (eg, the cross section shown in FIG. 3). As the tow passes through the die, it is molded and partially cured to form the required shape. There may be more than one steam die, followed by several drying sections that send hot air to the rods to remove excess steam / moisture. The rod is then fed onto the orthotic device, where it is withdrawn and cut to the desired length.

When the cooling element of FIG. 3 is used in the product of claim 1, such that a portion of the hole in the tubular element coincides with at least a portion (ie, the bottom edge) of each groove (channel) 90'. It should be understood that the diameter of the hole 3a (which can be referred to herein as dimension "A") is large enough. Therefore, it should be understood that the outer groove or channel 90'of the cooling element 40' partially overlaps the hole 3a of the hollow acetate tube 3. During use, hot steam from the tobacco plug (heated by the conventional method) is sucked into the channel 90'of the cooling element 40'through the hole 3a of the hollow acetylate tube 3 and then the final acetylate plug 5 Is sucked into the smoker's mouth through it. The cooling element 40'provides sufficient cooling, which is an effect not expected from the cellulose acetate material.

Experiment The cooling elements (B, C, D, E) of the present invention were produced. The cooling elements B and C have a cross section similar to that shown in FIG. 3 and have no central hole or hole. Therefore, the cooling elements B and C have a substantially circular cross section with an outer circumference of 22.30 mm and five channels with a depth of 1.2 mm. The cooling elements D and E, including the central hole, are as shown in FIG. The cooling elements D and E also have a substantially circular cross section with an outer circumference of 22.30 mm and five channels with a depth of 1.2 mm, but include a central hole with a diameter of 1.2 mm. Cooling elements B, C, D and E were tested against conventional PLA cooling elements (A) in HNB products.

The five HNB products shown in FIG. 1 were assembled for testing. Each comprises one of the cooling elements of the invention B, C, D, E or Comparative Example A (a known PLA product). Cooling elements A, C and E were used with a hollow acetate tube (element 3 in FIG. 1) having an outer circumference of 22.30 mm and a wall thickness of 1.3 mm. Cooling elements B and D were used with a "thin wall tube (TWT)" hollow acetate tube (element 3 in FIG. 1) having an outer circumference of 22.30 mm and a wall thickness of 0.8 mm.

FIG. 4 compares the pressure drop (mmWG) associated with the cooling elements (B, C, D, E) of the present invention and the conventional PLA cooling element (A). This indicates that the profiles are similar, indicating that the cooling elements of the invention are excellent heat sinks in THP products and are suitable alternatives to PLA. The cooling elements of the present invention can therefore provide biodegradable alternatives to known PLA cooling elements. It can be seen that B and C (without the central hole) show that the performance is closer to PLA and works better than D and E in this test.
