Description

Cigarette packaging products

This invention relates to cigarette packaging products.

The cigarette-like packaged product has a structure in which a cigarette containing a volatile flavor (for example, menthol) is contained in a package (for example, a paper package). In the storage of such cigarette-packed products, the crystallization of volatile flavors adheres to the cigarettes and impairs the appearance. The crystallization of volatile perfumes is primarily due to the reduced ambient temperature at which the paper package is placed. That is, when the volatile flavor contained in the cigarette is stored in the package at a certain temperature, the volatile flavor is released and saturated in the state of steam. Saturated volatile perfume vapors will reduce the saturated vapor pressure as the temperature decreases. Therefore, part of the vapor will not be present and the remainder will be produced. The residue is not precipitated by the inner wall of the package, the paper present between the package and the cigarette, and the like. However, when the residue is not completely absorbed for some reason, crystals are precipitated. At this time, once the crystal is precipitated to the cigarette, the appearance of the cigarette is impaired.

U.S. Patent No. 5,975,288 discloses a tobacco storage bin having a humidity modifying device containing a liquid absorbent body therein and controlling internal humidity during containment and storage of the tobacco product.

U.S. Patent No. 4,934,524 is directed to the invention of a package for storing moisture-containing articles, such as cigarettes. The document describes a package such as a cigarette In products that have been stored for a long time, maintain proper moisture content. The package includes an upper cladding layer having a low moisture permeability, a container, and a moisture control medium dispersed in the upper cladding layer.

Japanese Laid-Open Patent Publication No. Hei 2-109879 discloses a package comprising a container and a humidity conditioner disposed in the container, and the humidity conditioner has an absorbing layer for holding a humectant.

However, the purpose of the above three documents is to moisten tobacco products such as cigarettes, and it is not possible to suppress the crystallization of volatile flavors contained in cigarettes.

On the other hand, it is known that the adsorbent is disposed in the cigarette itself, for example, in the filter. Although the purpose of the adsorbent disposed in the filter is to reduce the composition or control the fragrance by sucking the components in the mainstream smoke, it is effective for suppressing the crystallization of the volatile flavor. However, in order to suppress crystallization, when the adsorbent is disposed in a filter of a branded product in which the filter is not disposed with the adsorbent, the influence on the flavor is increased.

It is an object of the present invention to provide a cigarette-like packaged article which can prevent precipitation of crystals generated by volatile flavors of cigarettes in a package.

In order to solve the above problems, according to the first aspect of the present invention, a cigarette package product comprising: a package body, an inner wrapper contained in the package body and containing at least an adsorbent material on the inner surface side, And a cigarette containing volatile fragrance contained in the aforementioned inner wrapping paper.

According to a second aspect of the present invention, a cigarette-packed product comprising: a package, a cigarette containing a volatile fragrance contained in the package, and the packaged in the package together with the cigarette; An insert containing an adsorbent material in the body and at least on the side of the aforementioned cigarette.
