Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing body that deodorizes aversive odors such as body odor, tobacco odor, mold odor, etc. felt in a living space such as the interior of an automobile.

Conventionally, this type of deodorizer has been designed to dissipate, for example, a gel-like deodorizer inside a case with a lid, and to adjust the degree of opening of the lid to release active components of the deodorizer into the room. I'm letting you do it.

However, with the above conventional examples, it is very difficult to adjust the amount of volatile components emitted by the deodorant, and the deodorant may become unusable in a short period of time, or the amount of emitted information may be reduced. There is a problem that when the amount increases, the odor becomes too strong and becomes a bad odor in itself.

Therefore, in view of the above problems, the present invention covers the surface of a deodorant with a polyolefin resin or vinyl resin film having gas permeability, and also coats the outer surface of the film with the FA Di tension type of the film. The purpose of this invention is to solve the above-mentioned problems by installing a breathable member that suppresses this.

The present invention will be explained in detail below with reference to embodiments shown in the drawings. In FIG. 1, numeral 1 indicates the overall structure of the deodorizing body. 2
is mainly composed of cellulose polymer material and has a thickness of 3 to 1Q
The pad 2 is made of a non-woven fabric with a diameter of 1.0 mm and is impregnated with, for example, 10 to 30 ml of vegetable essential oil containing limonene as a main component, which can remove malodorous substances by neutralizing the substance. This vegetable essential oil is used as a deodorant in this example.

3 is a bag made of polyethylene film having a thickness of 20 to 500 μm, for example.

4 is a breathable member made of a nonwoven fabric made of cellulose polymer.

The bag 3 is manufactured as follows. That is, the air permeable member 4 is attached to one side of a rectangular polyethylene film, and in this state, the other side of the film is bent inward, and the two sides of the film are attached together with the air permeable member 4. Heat and press. Thereby, the bag body 3 having the breathable member 4 fixed to the outer circumferential surface is obtained. The pad 2 is housed inside the bag 3 thus obtained, and the opening of the bag 3 is sealed A by thermocompression bonding to form the deodorizing body 1.

The deodorizing body 1 having the above structure is stored, for example, as shown in FIG. 2. That is, the deodorizer 1 is placed on the support shelf 5a of the cap 5, and the support shelf 5a is inserted into the case 6. The odor of the deodorizing body 1 is released through a through hole 6a provided in the case 6. Incidentally, the case 6 can be mounted, for example, at an appropriate location in the interior of an automobile by means of its mounting surface 6b.

In the above configuration, the operation will be explained next. The deodorizing component of the deodorant is emitted into the case 6 through the bag body 3 and the ventilation member 4, and subsequently into the vehicle interior space through the through hole 6a. The bag 3 is made of a gas-permeable polyethylene film, so the gas permeability is used to transmit and release the deodorizing ingredient. The amount of deodorizing ingredients released is extremely small.

This point is shown in FIG. 3 by showing the relationship between the amount of deodorizing component released and the thickness of the polyethylene film of the bag body 3. Figure 3 shows 2 at room temperature.
The amount of emission (mg/self) after 4 hours is plotted. As can be understood from the figure, the amount of divergence is extremely small. By the way, when the opening degree of the conventional lid is adjusted to the minimum (0.5 mm x l
2π) is also about 10 mg'/cJ.

Further, FIG. 3 shows how the amount of emission differs depending on the thickness of the polyethylene film of the bag body 3 and the density of the polyethylene film. In the same figure, a is density 0
．． 91B, b indicates a density of 0.924. As understood from FIG. 3, the amount of deodorizing component emitted can be adjusted by adjusting the thickness and density of the polyethylene film constituting the bag body 3.

Note that the film thickness is preferably 70 to 120 μm.

By the way, as shown in FIG. 2, the deodorizing body 1 is housed in a case 6, and therefore, the ambient temperature around the deodorant 1 becomes quite high depending on the environment in which it is used.

As is well known, polyethylene film is heated to
If the expansion is suppressed, it will deform. Therefore,
The bag body 3 made of polyethylene film is thermally expanded and deformed (expanded). Due to this deformation, the bag body 3
The surface area changes, which causes a change in the amount of deodorizing ingredients released.

However, according to this embodiment, the outer circumferential surface of the bag body 3 made of polyethylene film is provided with a vent made of a nonwoven fabric mainly composed of cellulose thread polymer, which has a considerably small amount of deformation (elongation) with respect to temperature and pressure. Since the elastic member 4 is attached, thermal expansion and deformation of the bag 3 can be suppressed by the member 4. Therefore, it is possible to reduce changes in the amount of the deodorizing component emitted, and it is possible to prevent the deodorizing body from becoming difficult to remove from the case 6 when replacing it.

Incidentally, FIG. 4 shows the results of measuring the bulge width of the bag 3 with and without the air permeable member 4 at an atmospheric pressure of 80°C. In the figure, a indicates a device without a breathable member, and b indicates a device with a breathable member. As can be understood from this FIG. 4, it can be seen that the width of the bulge in a is considerably large with the passage of time. On the other hand, in b, the bulge width is small, about 1 of that in a.
/3.

FIG. 5 shows another embodiment of the invention.

Regarding this, for example, a polypropylene film 3 with a thickness of 30 to 200 μm for the purpose of adjusting the amount of emission.
For example, a breathable member 4 made of a nonwoven fabric containing cellulose polymer as a main component is bonded by thermocompression on the entire surface through a polyethylene film 7 with a thickness of 10 to 50 μm, and this three-layer structure is formed into a polypropylene sheet with a thickness of 300 μm or more. 8 and heat weld 3 of the 4 sides to make the whole bag shape.

Then, this bag is impregnated with deodorant, for example, thickness 5~
A 15 mm piece of felt 2 whose main component is cellulose polymer is inserted, and the remaining one side is heat welded.

In the deodorizing body 1 having such a structure, since the polyethylene sheet 8 is thick, the deodorizing component is not diffused through the sheet 8 much, and is mainly diffused through the film 3.7. Note that since the sheet 8 side has a thick wall, thermal expansion deformation is small.

The present invention is not limited to the above-described embodiments, but can be modified in various ways as described below.

(1) Polyethylene was used as the material for the film covering the surface of the carrier, such as nonwoven fabric or felt, impregnated with the deodorant, but polyolefin resins such as polypropylene may also be used, or vinyl chloride, acetic acid, etc. Vinyl resin systems such as vinyl may also be used. Furthermore, it is of course possible to have a multilayer structure in which these resin films are appropriately combined.

(2) The material of the breathable member is not limited to non-woven fabric whose main component is cellulose polymer, but may also be carbon fiber or wire mesh. Bye.

(3) In the present invention, deodorants also include fragrances.

(4) Although the sheet 8 in FIG. 5 is made of polypropylene resin to provide gas permeability, it may be made of a force-impermeable resin.

(5) The deodorant may be in liquid form or gel form, and its form does not matter.

(6) The present invention can be used not only for automobiles but also for general household use.

In summary, the effects of the present invention are listed as follows.

(By using an Al polyolefin resin or vinyl resin film, the amount of the deodorizing component of the deodorant released can be reduced to a very small amount, thus preventing short-term consumption of the deodorant and odor formation due to excessive release. can.

(bl) Thermal expansion and deformation of the film can be suppressed by a breathable member attached to the outer surface of the film, and therefore, it is possible to prevent the amount of deodorizing agent released from changing significantly due to thermal expansion and deformation of the film. This prevents it from becoming difficult to remove from the container when replacing.
