Description

Heating cigarette limiting element

Technical Field

The utility model relates to a limiting element for heating cigarettes, and belongs to the technical field of novel tobacco products.

Background

The cigarette is heated by transferring the tobacco fragrance to a consumer in a heating and non-burning mode, so that the tobacco is heated only at a lower temperature (generally lower than 500 ℃), tar and a large amount of harmful compounds caused by high-temperature burning of the tobacco are avoided, and secondary smoke is not generated due to the fact that basically no side-stream smoke exists, and the public environment is not affected, so that the cigarette is more and more concerned and favored by the consumer.

Currently, the types of heated cigarette are classified into an ordered sheet type heated cigarette (iQOS compatible cartridge of Feimo corporation), an unordered sheet type heated cigarette (GLO compatible cartridge of Yinmei tobacco, Lil compatible cartridge of Korea tobacco, Nissan International cartridge of Nissan tobacco, etc.), and a pellet type heated cigarette (DUBLISS) according to the form of a smoke releasing material. Among these, the sequential sheet-type heated cigarettes typically require a support element between the sheet section and the cooling section. In the prior art, a hollow acetate fiber tube or a paper tube is mainly used as a limiting element to limit the displacement of the thin sheet when the thin sheet type heating cigarette is inserted into the inner core type heating smoking set. The hollow acetate fiber tube is subjected to unprecedented size adjustment, so that the displacement of the sheet can be better limited, but the sheet is subjected to heat melting deformation; although the paper tube has good heat resistance, when the cigarette is inserted into the inner core to heat the smoking set for smoking, the thin sheet can be greatly displaced into the paper tube, so that the smoke release is insufficient, and the problem is particularly more prominent when the thin sheet section is shorter. Therefore, it is desired to develop a stopper for a heated cigarette having excellent heat resistance and excellent stopper effect on a sheet.

Detailed Description

The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.

As shown in figure 1, a sheet-type heated cigarette containing a limiting element comprises a sheet segment 1, a limiting element segment 2, a cooling segment 3 and a filtering segment 4.

As shown in fig. 2 to 4, the utility model provides a heated cigarette limiting element for a limiting element section 2, which comprises a wrapping part 21 and a limiting part 22 arranged inside the wrapping part 21.

In specific implementation, the cross-sectional area of the limiting component inside the wrapping component accounts for 20% -70% of the cross-sectional area of the inner hole of the wrapping component, such as 25%, 35%, 40%, 50%, 60%, 70% and the like. If the cross section area percentage is lower than 20%, the limiting effect on the thin sheet is not good; if the cross section area percentage is higher than 70%, although the limiting effect is good, the smoke can be greatly adsorbed, and the smoke release is insufficient. In this embodiment, the cross-sectional area of the position limiting member accounts for 50%.

In specific implementation, the wrapping component is a paper tube and can be prepared by a spiral or staggered overlapping process, the circumference is 17-24mm, the length is 5-15mm, and the wall thickness is 0.1-0.5 mm. In this example, the paper tube as the wrapping member had a circumference of 22.0mm, a length of 7.0mm and a wall thickness of 0.25 mm.

In specific implementation, the limiting component is a paper board with a cross section having a specific shape, such as a V-shaped paper board, a W-shaped paper board, a polygonal paper board, a rolled paper board and the like. The thickness of the paperboard of the limiting component is 0.05-2.0 mm. If the thickness is less than 0.05mm, the limiting strength is not enough; if the thickness is higher than 2.0mm, the limiting part is not easy to process.

In specific implementation, the paper board used as the limiting part is a solid paper board or a corrugated paper board.

As shown in fig. 2 to 4, the present embodiment designs several kinds of limiting elements for heating cigarettes with different structures, which are all composed of a wrapping part 21 and a limiting part 22 disposed inside the wrapping part 21. Wherein: as shown in fig. 2, the position limiting member 22 is a solid cardboard with a W-shaped cross section; as shown in fig. 3, the limiting member 22 is a corrugated board with a triangular cross section; as shown in fig. 4, the stopper member 22 is a corrugated cardboard having a roll-shaped cross section.

In specific implementation, the solid paperboard or corrugated paperboard base paper is at least one of natural cellulose paper, aluminum foil paper, natural cellulose paper/aluminum foil composite paper and tobacco repulping paper. Compared with the acetate fiber filter stick, the natural cellulose paper, the aluminum foil paper, the natural cellulose paper/aluminum foil composite paper and the tobacco re-papermaking have the advantages of no shrinkage under heating and environmental friendliness; meanwhile, when the tobacco is heated in papermaking, the tobacco fragrance can be released, and the function of enhancing the fragrance of smoke is achieved. The solid paperboard shown in fig. 2 is a tobacco repulping paper; the corrugated cardboard shown in fig. 3 and 4 is a parchment paper (belonging to a natural cellulose paper).

In specific implementation, the natural cellulose paper/aluminum foil composite paper and the tobacco repulping paper can also contain 0-15% of glycerin by mass of the paper board, such as 0%, 5%, 8%, 13% and the like, and have the effects of reducing the smoke temperature and increasing the smoke amount. If the content of glycerin is higher than 15%, the strength of the corrugated paper roll is low, and the limiting effect is poor. The tobacco reconstituted paper shown in FIG. 2 contains 5% glycerin; the parchment papers shown in fig. 3 and 4 contained 8% glycerin.

The embodiment also provides a manufacturing method of the limiting element, which comprises the following steps: firstly, the solid paperboard or the corrugated paperboard is sprayed with glycerin according to needs to be made into a specific shape, and then the solid paperboard or the corrugated paperboard is refilled into a paper tube, and then the limiting element with the required length is obtained after cutting.

For example, the method for preparing the limiting element shown in fig. 2 comprises the following steps:

1) spraying 5% glycerol on the reconstituted tobacco paper to prepare glycerol-containing tobacco and then making paper;

2) and (3) making the tobacco containing the glycerol into a W-shaped cross section, filling the tobacco into a paper tube with the circumference of 22.0mm and the wall thickness of 0.25mm, and cutting to obtain the 7mm limiting element.

The present invention is not limited to the above exemplary embodiments, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
