Description

[Detailed Description of the Invention] This invention relates to a cigarette holder in which a cylindrical cigarette insertion part and a mouthpiece are integrally formed of synthetic resin.

This type of cigarette holder has a simple structure and is inexpensive, so it is used for general purposes.

However, since it only connects the cigarette insert and the mouthpiece, it has no effect on removing substances harmful to the human body contained within the cigarette, and is merely used as a holder. Ta.

Even in the above-mentioned conventional cigarette holder, this idea allows for the removal of harmful substances to a sufficient extent by integrally forming the obstruction member within the holder and separating the obstruction member within the range that does not impair the ease of molding. It is designed to prevent harmful substances from leaking into the mouth.

This invention will be explained in detail below using illustrated examples.

Reference numeral 1 denotes a holder main body made of transparent synthetic resin, which has a cylindrical cigarette insertion part 2 and a flat-shaped mouthpiece 3 formed by crushing a cylindrical body.

The inside of the mouthpiece 3 is used as it is as a flue 4, and the mouthpiece end 3a is wide and open.

In addition, a partition 6 is integrally formed on the inner step 5 formed at the boundary between the cigarette insertion part 2 and the mouthpiece 3, and a core 7 of a required length to be located inside the mouthpiece is integrally formed in the partition 6. It is.

This core 7 has a tubular shape with a closed end 7a, and has a suction port 3.
A slit 8 is formed between the flue 4 and the wall of the flue 4, so that the inside of the mouthpiece has a slit inside the flue 4.

Note that 9 in the figure is a rib protruding from the inner wall of the flue in order to form a slit 8 on the outside of the core.

In addition, a plurality of cut grooves 10 are formed in the base end 7b of the core 7, that is, the part connected to the partition 6, so as to face the inside of the tobacco insertion part 2. While communicating with the narrow gap 8, the cut groove 10
The opening on the slit side is formed small so that high-speed flow occurs there.

In the cigarette holder having the above structure, smoke flows from the cigarette insertion portion 2 to the mouthpiece 3 due to the suction force.

This flow first occurs through the plurality of cut grooves 10 in the core base 7b to the slit 8 around the core 7, and then passes through the flue 4 to the mouthpiece 3.
to arise.

In addition, the flow of smoke becomes high speed when it flows out from the opening of the cut groove 10 into the slit 8, and collides with the inner wall or rib 9 on the flue side, causing harmful substances such as tar and nicotine contained in the smoke to be removed. Separate.

The separated product accumulates around the core 7 in a dark brown color.

The example shown in FIG. 4 is a case in which the flue 4 is filled with a filter 11, and the filter 11 can further remove harmful substances.

As mentioned above, this idea consists of integrally molding the cylindrical cigarette insert part 2 and the mouthpiece with a wide opening at the end of the mouthpiece using synthetic resin, and also forms a cigarette at the inner boundary between the cigarette insert part 2 and the mouthpiece 3. A partition 6 is formed in the stepped part 5, and a core 7 formed integrally with the partition 6 provides a narrow gap 8 in the mouthpiece, and a plurality of cut grooves 10 made in the base end 7b of the core allow the tobacco to be differentiated. The inside of the cigarette insert and the mouthpiece are communicated with each other, and harmful substances in the smoke are removed at the proximal end 7b of the core 7 and the surrounding slit 8, so that the cigarette insertion part and the mouthpiece are integrated. It has a healing effect compared to conventional disposable products that are simply formed.

In addition, the opening of the mouthpiece is made wide along with the internal flue to ensure smooth flow from the slit to the end of the mouthpiece, and eliminates narrow areas where moisture in the smoke can accumulate.
Even if you use it to smoke a few cigarettes, it won't cause any gunk to flow into your mouth.

Moreover, since the opening is wide, there is no need to inhale strongly, so it is easier to smoke than conventional products, and it has the advantage of being able to fill the mouthpiece with a filter to further improve the slime removal effect.

Furthermore, even if the core is formed protruding from the suction port side, the core is formed protrudingly from the insertion part side, and the cut groove is formed from the insertion part side, all of these directions are in the axial direction of the holder. It has the advantage of not requiring multiple steps during molding, and can be manufactured at low cost with a one-shot bottom shape, similar to conventional disposables.
