Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a holder for smokeless cigarettes, and more specifically to a holder for smokeless cigarettes that allows the user to enjoy the full smoking sensation of cigarettes through intake air without the need for ignition. Regarding folders.

(Prior Art and its Problems) Cigarettes have long been used as a luxury item since ancient times, but in recent years, the harmful effects of cigarettes have been widely discussed. It is said that the harm caused by cigarettes is mainly caused by the combustion products of the cigarette leaves, and not only is it a health problem for the smoker himself, but recently the impact of the smoke and odor produced by combustion on the surrounding environment has also become an issue. Ta.

Traditionally, one way to solve these problems is to extract nicotine, the main component of cigarettes,
A product has been developed in the United States in which this material is impregnated into a breathable plastic body and held in a cigarette-like container.

This product allows you to inhale nicotine and flavoring by simply holding it in your mouth and inhaling it, and since it does not require ignition, it naturally does not emit smoke or ash, and has the advantage that it does not cause any discomfort to those around you. have.

However, inhaling only nicotine and flavoring agents has the disadvantage that a sufficient smoking sensation cannot be obtained because the trace amounts of various aromatic components that cigarettes inherently have are insufficient.

The applicant has proposed a smokeless cigarette that solves the above-mentioned problems of the prior art and can provide the same smoking sensation as conventional cigarettes without requiring ignition (Japanese Patent Laid-Open No. 185361/1983 and Special application 1986-104026
(see specification).

The above-mentioned smokeless tobacco manufactured by the present applicant, as shown in Figure 4, has a molded article 1, which is made by impregnating tobacco powder with nicotine, tobacco flavor extract, etc. and molding it with a binder to make it air permeable, and is held in a holder 2.
By inhaling air through the mouthpiece 3, circulating air through the cigarette molded body 1, evaporating components such as nicotine in the molded body 1, and inhaling this, the same smoking sensation as with conventional cigarettes can be achieved. It gives

However, in the above-mentioned smokeless tobacco industry, an appropriate amount of nicotine and tobacco extract flavor are generated and inhaled from the molded product through intake air, so it is difficult to control the amount of components such as nicotine and flavor that are impregnated into the cigarette molded product. It is necessary to adjust the amount of these components generated, adjust the air permeability of the molded product, etc., and the structure of the holder is extremely important in order for the cigarette molded product to exhibit its full functionality. I found it.

In other words, since the cigarette molded product is made by molding tobacco powder into a breathable (porous) material, it is not only difficult to keep its size strictly constant, but also due to drying, moisture absorption, etc. Subtle changes in size occur.

Therefore, no matter how precise the size of the holder is, when holding a cigarette molded object in the holder, if the size of the molded object is small,
The molded body cannot be firmly fixed in the holder. Even if it were possible to hold it by another means, as the size of the molded body changes, the distance between the molded body and the holder will also change, resulting in a change in the flow rate of the inhaled air, resulting in a decrease in the amount of nicotine etc. that can be inhaled. There is a problem that the amount of ingredients changes and a desired smoking sensation cannot be obtained.

On the other hand, if the size of the cigarette molded object is too large, it is difficult to hold the molded object in the holder, and if it is forced into the holder, the molded object will be compressed and the breathability will decrease, making it easier to inhale. Also, since there is no gap between the molded body and the holder, if you forcefully inhale, the concentration of nicotine etc. becomes too high, which also causes the problem that the desired smoking sensation cannot be obtained. do.

Therefore, an object of the present invention is to provide a holder for smokeless cigarettes that can always generate and inhale an appropriate amount of components such as nicotine and tobacco extract flavor, despite slight variations in the size of the cigarette molded product. be.

(Means for solving problems) The above object has been achieved by the present invention as described below.

That is, the present invention consists of a first cylindrical body that constitutes an air flow path, and a second cylindrical body that can be removably fitted with the first cylindrical body and that constitutes a suction port,
In a smokeless cigarette holder in which the fitting part of the second cylindrical body also serves as a holding part for the cigarette molded body, the inner surface of the holding part has a plurality of linear ribs that gradually slope toward the back from the end. This is a holder for smokeless cigarettes that is characterized by the following:

(Function) By providing a plurality of linear ribs that gradually slope toward the back from the end on the inner surface of the molded body holding portion of the mouthpiece, slight variations in the size of the cigarette molded bodies can be fully accommodated. In addition, the amount of air flowing inside the holder can be adjusted, and nicotine, flavor components, trace components of cigarettes, etc. can be generated effectively and constantly.

(Example) Next, the present invention will be described in more detail with reference to Examples.

As shown in FIGS. 1 to 4, one example of the smokeless cigarette holder of the present invention includes a first cylindrical body 11 constituting an air flow path, which can be removably fitted to the first cylindrical body 11 at its ends, and has a cylindrical body 11 that forms an air flow path. The fitting part of the second cylindrical body 12 also serves as the holding part 14 of the cigarette molded body 13, and the holding part 14
It is characterized in that a plurality of linear ribs 15 are formed on the inner surface thereof, which are gradually inclined from the end toward the back.

The first cylindrical body 11 of this embodiment, as shown in its cross section in FIG. It is molded from plastic such as polypropylene by injection molding or the like.
The left side of this cylindrical body 11 is an air flow path, and the right side is formed with a first step 16, a second step 17, and a small protrusion 18.

The second cylindrical body 12 is likewise a cylindrical body made of plastic, and has a total length of, for example, 25 mm as shown in the first figure.
35mm to 35mm, outer diameter 7 to 10mm and thickness 0.5 to 2mm
It is formed to about the same size.

On the left side thereof, a holding part (fitting part) 14 having a step with a length of approximately 6 to 10 mm is formed, and a second annular small protrusion 19 is formed on the surface thereof.

The outer diameter of the portion where the holding portion 14 is formed is approximately the same as or slightly smaller than the inner diameter of the portion of the first cylindrical body 11 where the first step 16 is formed, and is schematically shown in FIG. As shown, this holding part 14 can be inserted and fitted into the first stepped part 16 of the first cylindrical body 11. During this insertion, the small protrusion 19 hits the small protrusion 18, and
The second cylindrical body 12 is fitted and fixed to the first cylindrical body 11 by penetrating into the inside thereof and producing a small "click" sound.

The fitting portion 14 of the second cylindrical body 12 constitutes a fitting means for the first cylindrical body 11 as described above, and also serves as a holding portion for holding the cigarette molded body 13 inside thereof.

That is, this holding part 14 has an inner diameter somewhat larger than the outer diameter of the cigarette molded body 13, and is designed to be able to insert and hold the cigarette molded body 13 therein.
As shown in FIGS. 1 and 2, the inner surface of the holding portion 14 has three ribs 15 that gradually increase in thickness from the end toward the mouthpiece on the right side.
is formed.

Such a rib 15 has a width of about 1 mm, a length similar to that of the holding part 14, or a length before and after the holding part 14, and the thickest part is about 0.1 to 0.5 mm. By inserting the cigarette molded body 13 into the holding part 14 in which such ribs 15 are formed, the cigarette can be held even if the size of the cigarette molded body 13 is somewhat smaller than the inner diameter of the holding part 14. The molded body 13 is firmly fixed in the holding part 14 by the ribs 15. Therefore, by forming the holding portion 14 to be somewhat larger than the outer diameter of the cigarette molded body 13, the outer diameter of the cigarette molded body 13 can be adjusted somewhat, for example, within the range of the thickness of the rib 15. Even if it fluctuates, the cigarette molded object 13
It is possible to always firmly hold the inside of the holding part 14.

Furthermore, even if the size of the cigarette molded body 13 varies slightly, if the force when pushing the molded body 13 into the holding portion 14 is kept almost constant, the existence of the ribs 15 will allow the cigarette molded body 13 to The outer surface of the holding part 14
Since a certain small gap is always formed between the inner surface of the cigarette and the inner surface of the cigarette, when air is inhaled from the mouthpiece, the air passing through this gap and the air that has passed through the cigarette molded body 13 are mixed. The ratio becomes constant, and mixed air containing a constant concentration of components such as nicotine can be inhaled with constant inspiratory force.

In the holder of the present invention as described above, when the cigarette molded body 13 is inserted and held in the holding part 14 of the mouthpiece shown in the first figure, and this is inserted into the end of the cylindrical body 11 shown in the third figure, the small protrusion 18 and 19 are engaged and firmly fixed. In this state, the cigarette molded body 13
Near the tip of the second step 1 of the first cylindrical body 11
It is fixed against the corner of 7 and does not move inside.

The present invention has been described above by exemplifying a preferred embodiment, but the holder of the present invention has a plurality of linear ribs formed on the inner surface of the holding portion, which are gradually inclined from the end toward the back. As long as it is, various other aspects can be included. Further, the number of ribs 15 that characterize the present invention may be plural, for example, it is natural that the number of ribs 15 may be other than two, four, five, etc.

Incidentally, the cigarette molded article referred to in the present invention may be one described in Japanese Patent Application Laid-open No. 185361/1982, but the most preferable molded article is one described in Japanese Patent Application No. 104026/1983. It is. The molded product is made by shaping tobacco leaves (powdered or chopped leaves) into a predetermined shape and breathability using a binder resin that does not easily absorb components such as nicotine, and impregnating them with necessary components such as nicotine and tobacco extract flavor. It is something that If the binder resin is a material that absorbs components such as nicotine, it is possible to generate nicotine, but this is insufficient.

(Effects) According to the present invention as described above, by providing the inner surface of the holding portion of the mouthpiece of the holder with a plurality of linear ribs that are gradually inclined from the end toward the back, the cigarette molded body is In addition to being able to sufficiently deal with slight variations in size, the amount of air flowing inside the holder can be adjusted, and nicotine, flavor components, or trace components of cigarettes can be generated effectively and constantly.

On the other hand, in the case of a holder without such ribs, the size of the cigarette molded body must always be constant, and it is difficult to mold the cigarette molded body to a constant outer diameter. This is actually difficult for the reasons already mentioned, so if the size of the cigarette molded body is too small, it will be difficult to fix the molded body and it will also be difficult to inhale certain components. On the other hand, if the size of the molded body is too large, the molded body must be forced into the molded body, which similarly makes it difficult to inhale certain components. In the present invention, these problems are easily solved.
