Description

Hollow burst bead filter stick and aerosol generating product comprising same

Technical Field

The utility model relates to the field of cigarette filter stick preparation, in particular to a hollow burst bead filter stick and an aerosol generating product containing the same.

Background

With consumer importance on health problems and the increasing demand for personalized experience of cigarette products, the tobacco industry is continuously responding to consumer demand upgrading, and various smoking articles with tar and harm reducing effects are developed. Wherein, the heating cigarette is different from the traditional cigarette product in the cigarette heating mode, so that the heating cigarette can provide healthier smoking experience while meeting the sensory requirements of consumers on the cigarette product.

The existing aerosol generating products comprise a smoke generating section, a supporting section, a cooling section and a filtering section, wherein the supporting section, the cooling section and the filtering section can all use tow-shaped filter sticks, and the filter sticks are usually acetate tow filter sticks (acetate fibers are hereinafter abbreviated as acetate fibers) which can filter harmful components in smoke. The solid filter stick has the characteristic of high retention rate, the retention rate of smoke needs to be reduced in the design of heating cigarettes, and a better method in the industry is to make the filter stick into a hollow filter stick.

At present, the production of the hollow filter stick basically adopts the step of adding a rigid stick at the rear end of the converging and gathering of the horn mouth of a conventional filter stick forming machine, so that a hollow structure is formed at the position occupied by the rigid stick after the acetate fiber bundles are gathered.

With the continuous upgrading of cigarette flavoring technology, each section of the cigarette gradually has flavoring requirements, and particularly for the novel tobacco product heating cigarette, the supporting section is usually an acetate fiber hollow filter rod. The section is close to a heat source, the smoke temperature is higher than that of the lip-end acetate fiber filtering section, and the section is more suitable for volatilization and release of flavoring substances, so that the section has good application prospect in flavoring the hollow filter stick used for the supporting section.

With respect to the current hollow filter rod processing technology, the available flavoring modes are fewer, and the main processes at present are as follows: 1. adding soluble essence into plasticizer for perfuming; 2. adding granular perfume into acetate fiber before gathering; 3. directly soaking the formed hollow filter stick in the flavoring substances to adsorb the flavoring substances; 4. and coating or spraying flavoring substances on the inner surface of the hollow cavity of the formed hollow filter stick. The first of the above methods has the disadvantage that: 1. only the flavors compatible with the glyceryl triacetate can be selected, and the selection range of the essence and the flavor is narrow. 2. The flavored glyceryl triacetate can circulate throughout the system, resulting in a cumbersome replacement of the flavoring formulation, requiring thorough cleaning of the entire plasticizer application system. 3. The flavoring substances and the acetate fibers are integrated, namely, the flavoring substances are dispersed in the filter stick body, and when smoke passes through, the smoke preferentially passes through the hollow channel with small absorption resistance, so that the flavoring substances may not overflow sufficiently. The second method has the disadvantages that: 1. a separate set of granular perfume application system is needed, and the modification cost is high. 2. After the granular perfume is remoistened by condensed water, the granular perfume can be adhered to the whole forming channel, so that the equipment efficiency and the equipment stability are seriously affected. 3. There is also a combination of the flavoring material and acetate fibers, and the smoke is preferably passed through the hollow passage with low resistance to draw, resulting in insufficient spillage of the flavoring material. The third method is also problematic in that the flavoring substances are dispersed inside the filter rod body, and since the hollow cavity of the hollow filter rod is an air flow channel through which the smoke flows, the smoke will preferentially pass through the hollow cavity, so that the flavoring substances are impregnated into the hollow filter rod as a whole, and the flavoring effect on the smoke is not good, and thus it is essentially desirable to be able to flavor the smoke in the hollow channel. Aiming at perfuming the hollow channel of the hollow filter stick, the fourth method for independently coating or spraying the flavoring substances is complicated in steps and increases the cost.

The 'bursting beads' are small liquid rubber beads embedded in the tobacco filter tip, which wrap the liquid of different types of flavors, so that a smoker can burst in the smoking process, the liquid in the beads flows out, the taste of the cigarette is richer, the cigarette is more fragrant and moist, and the smoker can obtain more comfortable experience. The prior art mainly adds the explosion beads into the solid filter stick, but the explosion beads filter stick and the hollow structure cannot be combined, and the explosion beads cannot be stably clamped by the hollow structure, so the problem is currently a difficult point in the tobacco filter stick industry.

In summary, how to prepare the hollow explosion bead filter stick and ensure that the hollow structure can stably clamp the explosion beads is a problem that people need to solve.

The present utility model has been made to solve the above problems.

Disclosure of Invention

The utility model combines the explosion bead filter stick with the hollow structure, and the hollow structure can stably hold the explosion beads, so that the filter stick combines the advantages of the hollow filter stick and the explosion bead perfuming filter stick. The hollow explosion bead filter stick can more effectively supplement the fragrance of the smoke in the hollow channel, and the fragrance adding substances overflow more fully. The utility model designs the rigid rod with the hollow cavity, omits the complicated step of filling the explosion beads in the hollow cavity, directly fills the explosion beads in the hollow channel while the hollow filter rod is bundled to form the hollow, does not need to be provided with a special flavoring process, and has simple steps.

The utility model provides a hollow explosion bead filter rod, which comprises a filter rod main body 1, wherein a hollow channel 3 extending axially is arranged in the filter rod main body 1, explosion beads 2 are arranged in the hollow channel 3, and the diameter of the explosion beads 2 is larger than that of the hollow channel 3.

Preferably, the explosive bead 2 is a flavored explosive bead, which is internally wrapped with a liquid of a different type of perfume, and the perfume is selected from materials commonly used in the art. For example, the mint essence and the blueberry essence, more preferably, the spice also has a certain cooling function, has a certain heat absorption effect in the process of releasing the spice by heating, even can be added with some components for improving the heat absorption performance in the formula of the spice, so that the spice has a certain cooling function after being flavored, and can be matched with a cooling section to play a better cooling effect in heating a non-combustible cigarette, even can cancel the cooling section after the cigarette reaches a better cooling effect. In addition, a certain amount of fumigant can be added into the bead-blasting spice, so that the smoke amount is increased while the flavor is enhanced.

Preferably, the hollow channels 3 are one or more; at least one of the hollow channels 3 has the explosive beads 2 therein. The hollow channels 3 may be uniformly distributed or randomly dispersed in the filter rod body 1. It is of course more preferable that when the hollow passage 3 is one, it is located at the axial center, and when the hollow passage 3 is plural, one hollow passage 3 is provided at the axial center, and the remaining hollow passages 3 are dispersed around the hollow passage 3, and the diameters of the plural hollow passages 3 are not limited in size.

Preferably, one or more of the explosive beads 2 are arranged in the hollow channel 3.

The utility model also provides an aerosol generating product comprising the hollow bead-blasting filter rod. The hollow filter rod of the present utility model may be a support section, a cooling section or a filtration section of an aerosol generating article, wherein it is more preferred that it is directly used as a support section. Because the supporting section is closer to the smoke generating section and the temperature is high, the aroma components can be fully released; and the hollow structure perfectly meets the requirement of low interception filter stick for heating cigarettes.

The preparation device of the hollow burst filter stick comprises a beam-converging horn mouth N1, a rigid rod component N2, a control system N3, a pump N4 and a burst storage bin N5,

the rigid rod assembly N2 is arranged at the beam-converging horn mouth N1 of the filter rod forming machine, the rigid rod assembly N2 comprises a rigid rod 11, a cavity chamber 12 axially penetrating through the rigid rod 11 is arranged in the rigid rod 11, the cavity chamber 12 is filled with the explosive beads 2, the upstream end of the cavity chamber 12 is provided with an explosive bead inlet 13, and the downstream end of the cavity chamber is provided with an explosive bead outlet 14.

The preparation method of the hollow burst filter stick uses the preparation device provided by the utility model, and comprises the following steps:

A. filling the explosive beads 2 into the explosive bead storage bin N5;

B. starting the control system N3, and conveying the explosive beads 2 in the explosive bead storage bin N5 into the cavity chamber 12 of the rigid rod 11 through the explosive bead inlet 13 by utilizing the pump N4;

C. and (3) operating a filter rod converging process, wherein the rigid rod 11 occupies a hollow position in the filter rod converging process to form the hollow channel 3, at least one part of the explosion beads 2 at the downstream end of the cavity chamber 12 is exposed, and the exposed explosion beads 2 are removed from the explosion bead outlet 14 by friction force of filter rod base material tows along with forward advancing of the filter rod base material tows, and then enter the hollow channel 3, and the explosion beads 2 are in interference fit with the inner wall of the hollow channel 3 through friction force between the explosion beads 2 and the inner wall of the hollow channel 3 due to the fact that the diameter of the explosion beads 2 is larger than that of the hollow channel 3.

According to the utility model, the hollow filter rod is directly bundled to form a hollow, and meanwhile, the explosion beads are filled in the hollow channel, the wall material of the explosion beads has certain elasticity, the filter rod base material tows N6 firstly enter the bundling horn mouth, the bundled tows pass through the rigid rod, the forefront explosion beads are pushed by the explosion bead outlet to be leaked outside along with the forward advancing of the tows, the explosion beads at the forefront end are leaked to the outside along with the forward advancing of the tows, the explosion beads at the leakage half are received by friction force and then enter the hollow cavity of the filter rod, and the explosion beads are deformed in a recovery mode when being extruded in the hollow cavity of the rigid rod, and because the explosion beads are larger than the hollow cavity of the filter rod, the explosion beads are in interference fit with the hollow inner wall of the filter rod by utilizing the self elasticity of the explosion beads.

Preferably, the rigid bars 11 are one or more. The number of rigid rods 11 corresponds to the number of hollow channels 3. Furthermore, when the explosion beads 2 are not arranged in one hollow channel 3, the rigid rods 11 corresponding to the hollow channel 3 do not need to be provided with a hollow chamber, and the glue applying port is not needed.

Compared with the prior art, the utility model has the following beneficial effects:

1. because the hollow cavity of the hollow filter stick is an airflow channel through which smoke circulates, the smoke can pass through the hollow cavity preferentially, so that the overall flavoring effect of the hollow filter stick on the smoke is not good.

2. The rigid rod with the hollow cavity, the explosion bead inlet and the explosion bead outlet is designed, the complicated steps of additionally coating or spraying flavoring substances on the inner surface of the hollow cavity or additionally filling explosion beads in the hollow channel are omitted, the hollow filter rod is directly converged to form the hollow, and meanwhile, the explosion beads are filled in the hollow channel, a special flavoring process is not required, and the steps are simple.

3. If a hollow filter rod is molded first, two difficult problems exist in filling explosion beads into a hollow channel: if the size of the explosion beads is smaller than that of the hollow channels, the hollow channels cannot stably hold the explosion beads although the filling is easy. If the size of the blasting beads is larger than that of the hollow passage in order to stably hold the blasting beads, the blasting beads are difficult to fill into the formed hollow passage, and the blasting beads are easy to damage when extruded in the filling process. According to the utility model, the hollow filter rod is directly bundled to form a hollow, and meanwhile, the explosion beads are filled in the hollow channel, the filter rod base material tows firstly enter the bundling horn mouth, the tows after being bundled and gathered pass through the rigid rod, the front-end explosion beads are pushed by the explosion bead outlet to be leaked outside by half along with the forward advancing of the tows, and the explosion beads leak by half along with the forward advancing of the tows to be received by friction force and then enter the hollow cavity of the filter rod, and as the explosion beads are larger than the hollow cavity of the filter rod, the explosion beads are in interference fit with the hollow inner wall of the filter rod by the elasticity of the explosion beads. The hollow filter rod is directly bundled to form a hollow, and meanwhile, the explosion beads are filled in the hollow channel, and the diameter of the explosion beads is ensured to be larger than that of the hollow channel, so that the explosion beads are easily filled, and the hollow channel can be used for stably clamping the explosion beads.

4. When the spice formulas with different flavor characteristics are replaced, the type of the explosion beads in the empty chamber is replaced, the explosion beads are not related to other parts of the equipment, and the replacement is convenient.

5. The perfuming of the hollow filter stick can be completed by only adding the rigid stick on the existing filter stick converging equipment, and the equipment has low reconstruction cost and high efficiency.

6. Compared with the perfuming method of adding the soluble essence into the plasticizer, the flavoring essence has wide selection range, and can be prepared into explosive beads which are filled into the hollow cavity of the rigid rod. Compared with the perfuming method of adding the granular perfume into the acetate fibers before gathering, the utility model avoids the defects that the granular perfume is adhered to the whole forming channel after being wetted by condensed water, and the equipment efficiency and the equipment stability are affected.
