Description

The present invention relates to a collapsible seamless capsule and a filter and a smoking device including the same.

Conventionally, capsules have been widely used in the fields of medicine, cosmetics, health foods, and the like. In recent years, its applications have spread, and not only the conventional technique for increasing the strength of the capsule coating to make it hard to break but also a technique for making it easier to break are required. For example, by embedding a capsule containing a fragrance or the like in a cigarette filter and breaking the capsule when smoking, the demand for a capsule that can enjoy the scent of the capsule contents and the bursting sound and feel of the capsule is increasing. Therefore, there is a demand for a capsule that can be easily disintegrated by a smoker applying pressure with a finger when smoking. For example, Patent Document 1 discloses a disintegratable capsule containing a hydrophilic colloid in its shell. The capsules are said to be able to maintain their disintegration ability in a smoking device when exposed to the moisture provided by the smoker.

JP, 2015-37425, A

In recent years, there is an increasing demand for capsules having a strong scent and stimulus, and it is desired to enhance the scent when the capsule disintegrates. The fragrance at the time of capsule disintegration correlates with the amount of contents such as fragrance released at the time of disintegration. Therefore, the present inventor has tried to enhance the scent at the time of capsule disintegration by increasing the proportion of oily components such as flavors in the capsule contents. However, oily components such as fragrances have high volatility, and when a high content of oily components is contained, the contents such as oily components will volatilize from the capsule film over time, ensuring storage stability of the contents. There was a problem that it was difficult to do.
For example, when the content of the fragrance in the contents is increased by the film formulation of Patent Document 1, the volatile amount of the fragrance during storage of the capsule increases, so that it is difficult to keep the fragrance component in the capsule at a high concentration. there were. Furthermore, if the capsule coating is thickened to reduce the volatilization amount of the contents, the breaking strength of the capsule increases, and it is difficult to disintegrate the capsule by applying pressure with a finger, or the capsule deforms without cracking. There was a problem. In particular, Patent Document 1
As described above, generally-used capsules in which gelatin and glycerin are mixed have a problem that the breaking strength of the capsule is high and it is not easy to disintegrate the capsule and release the contents.
Further, it is possible to increase the content of the gelling agent component in the capsule film to suppress the increase in breaking strength and thicken the film, but in this case, the film component becomes highly viscous, making capsule production difficult. Will end up.

There is a demand for capsules capable of suppressing the volatilization of highly volatile capsule contents from the capsule film and having a disintegrating ability.

As a result of trial and error, the present inventor has found that the above problems can be solved by adjusting the formulation and thickness of the capsule coating, and completed the present invention.

The total weight of the capsules is preferably 17 to 17, for example in the case of capsules with a diameter of about 3.5 mm.
It is 25 mg, more preferably 18 to 24 mg, still more preferably 19 to 23 mg.

In a preferred embodiment, the capsule ruptures the capsule coating upon application of external pressure. In a preferred embodiment, the capsule pops upon popping and makes a popping sound.
