Description

DESCRIPTION TITLE OF THE INVENTION: NASAL CONGESTION RELIEVER TECHNICAL FIELD

[0001]

The present invention relates to a nasal congestion reliever to be mounted to

the nose to relieve nasal congestion.

BACKGROUND ART

[0002]

For example, cold, hay fever, or the like may cause symptoms of rhinitis such

as a stuffy nose. Patent Document 1 discloses a nasal pack as an example of a solution

for improving the symptoms of rhinitis such as stuffy nose. The nasal pack of Patent

Document 1 is mounted to the face in an attempt to improve the symptoms of rhinitis by

heating the nasal cavities or paranasal sinuses with its heating element.

PRIOR ART DOCUMENT PATENT DOCUMENT

[0003]

Patent Document 1: Japanese Unexamined Patent Publication No. 11-347059

SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION

[0004]

Unfortunately, the nasal pack of Patent Document 1 has a relatively large

mounting area which could be uncomfortable for some people wearing it.

[0005]

In view of the above, it is a technical object of the present invention to reduce

the mounting area of the nasal congestion reliever to be mounted to the nose in order to relieve the nasal congestion.

MEANS FOR SOLVING THE PROBLEM

[0006]

A nasal congestion reliever according to the present invention devised to solve

the problem described above is a nasal congestion reliever that is to be mounted to a

nose in order to relieve nasal congestion, the nasal congestion reliever including: a pair

of storage parts in which a chemical exothermic composition is stored; and a connection

part that connects the pair of storage parts, wherein the chemical exothermic

composition is a tableted product that is made by tableting a raw material. The

tableted product is a product that is made by tableting a raw material. The tableting is

about pressing a raw material using a tablet press into a form of a tablet (the same

applies to the following description).

[0007]

With this configuration, the chemical exothermic composition is a tableted

product and thus can have a small volume. Thus, the storage parts can be made

compact without compromising the exothermic temperature. Thus, the mounting area

of the nasal congestion reliever can be reduced.

[0008]

In the configuration described above, the connection part may be provided with

an elastic member that extends side walls of the nose when mounted.

[0009]

With this configuration, the nasal cavities can be expanded by the elastic

member, so that the effect of relieving the stuffy nose can be enhanced.

[0010]

In the above configuration, a distance between centers of the pair of storage parts may be 55 mm to 90 mm.

[0011]

With this configuration, the storage parts can be placed on acupuncture points

known as "nasal passages", stimulation of which is known to be effective against a

stuffy nose. Thus, it is possible to warm the "nasal passages" to thereby enhance the

effect of relieving the stuffy nose. When the elastic member is provided to the

connection part, the elastic member can be arranged at a position optimum for extending

the side walls of the nose outward, with the storage parts positioned on the "nasal

passages".

ADVANTAGES OF THE INVENTION

[0012]

With the present invention, the mounting area of the nasal congestion reliever

to be mounted to the nose in order to relieve the nasal congestion can be reduced.

EMBODIMENTS OF THE INVENTION

[0014]

Hereinafter, an embodiment of the present invention will be described with

reference to the drawings.

[0015]

is a schematic cross-sectional view taken along line X-X in (A). A nasal congestion

reliever 1 according to the present embodiment is to be mounted to the nose in order to

relieve nasal congestion, and includes a pair of storage parts 2 and a connection part 3

that connects the pair of storage parts 2. Each of the pair of storage parts 2 stores a

chemical exothermic composition 4. An elastic member 5 that extends the side walls

of the nose outward when mounted is provided to the connection part 3.

[0016]

The nasal congestion reliever 1 includes a front side sheet member 6, a back

side sheet member 7, an adhesive layer 8, and a peeling member 9.

[0017]

The front side sheet member 6 has both end sides in the longitudinal direction

provided with respective protruding parts 6a protruding to the front side, and the storage

parts 2 are formed by the protruding parts 6a and the back side sheet member 7.

Further, the elastic member 5 is arranged between the front side sheet member 6 and the

back side sheet member 7. The front side sheet member 6 and the back side sheet

member 7 bonded to each other using, for example, an adhesive (not illustrated).

[0018]

The protruding parts 6a each have a circular shape in plan view, and the

internal space of the storage parts 2 has a substantially cylindrical shape with a low

height. The overall shape of the front side sheet member 6, the back side sheet

member 7, the adhesive layer 8, and the peeling member 9 in plan view has a width

gradually increasing from the central position in the longitudinal direction toward the

center positions of the storage parts 2 in the longitudinal direction, and is a circular

shape at portions more on the end portion side than the center positions of the storage

parts 2 in the longitudinal direction.

[0019]

The adhesive layer 8 is formed on the back surface of the back side sheet

member 7. The peeling member 9 is attached to the back surface of the adhesive layer

8 while being capable of being peeled off from the adhesive layer 8. In the present

embodiment, the adhesive layer 8 is formed on the entire back surface of the back side

sheet member 7, but may be formed only in a partial region.

[0020]

The chemical exothermic composition 4 is an exothermic composition used in

what is known as disposable body warmers (chemical body warmers). This chemical

exothermic composition 4 utilizes the heat of oxidation of a metal, and generally includes metal powder such as iron powder, a metal halide such as salt, water, activated carbon powder, a water retention material, and the like. The chemical exothermic composition 4 may further include a temperature control agent for controlling the maximum exothermic temperature (see, for example, Japanese Patent No. 6273481) and the like.

[0021]

The chemical exothermic composition 4 is a tableted product that is made by

tableting a raw material. The shape of the tableted product is a substantially

cylindrical shape (circular shape in plan view) having a low height that matches the

shape of the internal space of the storage parts 2. However, the shape of the tableted

product is not limited to this, and may be, for example, a prismatic shape or the like.

[0022]

The area of the chemical exothermic composition 4 in plan view is, for

example, 200 mm2 to 500 mm 2 , more preferably 250 mm2 to 450 mm 2 , and most

preferably 300 mm2 to 400mm 2 . If the area of the chemical exothermic composition 4

in plan view is smaller than 200 mm2 , the effect of relieving a stuffy nose may not be

sufficiently obtained. If the area of the chemical exothermic composition 4 in plan

view exceeds 500 mm2 , a large amount of the chemical exothermic composition 4 is

required, and thus may result in a high manufacturing cost.

[0023]

The front side sheet member 6 and the back side sheet member 7 are breathable

materials, and are made of, for example, a non-woven fabric using polyethylene,

polypropylene, or the like. In the present embodiment, the front side sheet member 6

and the back side sheet member 7 are made of the same material, but may be made of

different materials.

[0024]

The moisture permeability of the front side sheet member 6 and the back side

sheet member 7 is 600 g/(m 2 -24h) to 20,000 g/(m 2 -24h), more preferably 1,000

g/(m 2 -24h) to 10,000 g/(m 2 -24h), and most preferably 2,000 g/(m -24h) to 8,000 2

g/(m 2 -24h) for example. The definition of moisture permeability (water vapor

permeability) conforms to JIS K 7129 (the same applies in the following description).

[0025]

If the moisture permeability is less than 600 g/(m 2 -24h), the temperature of the

chemical exothermic composition 4 may not rise quickly, and the stuffy nose may not

be swiftly relieved. If the moisture permeability exceeds 20,000 g/(m2 -24h), the

exothermic reaction of the chemical exothermic composition 4 may proceed too much

and the exothermic time might be short.

[0026]

Characteristics related to exothermic temperature (temperature on the skin side)

include rise time (time required for the temperature to rise from 31.5°C to 39.9°C in this

embodiment), maximum temperature, and duration (during which the temperature is

°C or higher in the present embodiment). Here, the method of measuring the

exothermic temperature conforms to the "ordinary method" of JIS S 4100 (the same

applies to the following description).

[0027]

The rise time is preferably, for example, 60 seconds or less, more preferably 50

seconds or less, and most preferably 40 seconds or less. If the rise time exceeds 60

seconds, it may be difficult to swiftly relieve the stuffy nose after the nasal congestion

reliever 1 is mounted.

[0028]

The maximum temperature is, for example, preferably 43°C to 65°C, more

preferably 43°C to 60°C, and most preferably 43°C to 55°C. If the maximum

temperature is lower than 43°C, the temperature fails to reach approximately 43°C

required to improve blood flow. If the maximum temperature exceeds 65°C, there is a

risk of low temperature burns and the exothermic time might be short.

[0029]

The duration is preferably, for example, 10 minutes to 3 hours, more preferably

minutes to 2 hours, and most preferably 10 minutes to 1 hour. If the duration is

shorter than 10 minutes, the stuffy nose relieving effect may fail to be sufficiently

obtained. If the duration exceeds three hours, there is a risk of low temperature bums,

and a large amount of the chemical exothermic composition 4 is required, which may

result in a high manufacturing cost.

[0030]

In the present embodiment, the chemical exothermic composition 4 comes into

contact with air via the protruding parts 6a of the front side sheet member 6 of the

storage parts 2, and thus the protruding parts 6a serve as aeration parts that bring the

chemical exothermic composition 4 into contact with air.

[0031]

The shape and material of the elastic member 5 are not particularly limited as

long as the side walls of the nose can be pulled outward when mounted. In the

illustrated example of Fig. 1, the shape of the elastic member 5 is a long plate shape and

a rectangular shape in plan view. As the material of the elastic member 5, for example,

synthetic resin such as polyester can be used.

[0032]

A distance d between the centers of the pair of storage parts 2 (chemical exothermic composition 4) in plan view is, for example, 55 mm to 90 mm, more preferably 60 mm to 85 mm, and most preferably 65 mm to 80 mm. When the distance d is less than 55 mm or more than 90 mm, the storage parts might be difficult to place on acupuncture points called "nasal passages", which are known to be effective against a stuffy nose when stimulated.

[0033]

Before use, the nasal congestion reliever 1 is put inside a bag made of a non

breathable material (not illustrated), and is airtightly stored. When the nasal

congestion reliever 1 is used, the nasal congestion reliever 1 is taken out from this bag,

and is mounted with the peeling member 9 on the back side peeled and the adhesive

layer 8 attached to the nose as illustrated in Fig. 2. In the illustrated example, the

centers of the pair of storage parts 2 (chemical exothermic composition 4) are arranged

on the acupuncture points known as "nasal passages".

[0034]

In the nasal congestion reliever 1 of the present embodiment configured as

described above, the chemical exothermic composition 4 is a tableted product and thus

can have a small volume. Thus, the storage parts 2 can be made compact without

compromising the exothermic temperature. Thus, the mounting area of the nasal

congestion reliever 1 can be reduced.

[0035]

The present invention is not limited to the above embodiment, and various

modifications can be made within the scope of its technical idea. For example, in the

above embodiment, the chemical exothermic composition 4 is stored between the

protruding parts 6a of the front side sheet member 6 and the back side sheet member 7,

but as illustrated in Fig. 3(A), a breathable bag member 10 storing the chemical exothermic composition 4 in advance may be stored between the protruding parts 6a of the front side sheet member 6 and the back side sheet member 7. In this case, the bag member 10, the protruding parts 6a, and the back side sheet member 7 serve as a storage part storing the chemical exothermic composition 4, and the bag member 10 and the protruding parts 6a serve as aeration parts that bring the chemical exothermic composition 4 into contact with air.

[0036]

Further, as illustrated in Fig. 3(B), the breathable bag member 10 storing the

chemical exothermic composition 4 in advance may be attached and fixed to the front

side sheet member 6 by means of an adhesive layer 11 on the back side. In this case,

the bag member 10 serves as a storage part storing the chemical exothermic

composition 4, and the bag member 10 serves as an aeration part that brings the

chemical exothermic composition 4 into contact with air. In this case, the front side

sheet member 6 and the back side sheet member 7 may be made of non-breathable

materials.

[0037]

Furthermore, in this case, before using the nasal congestion reliever 1, a

peeling member (not illustrated) is attached to the adhesive layer 11 of the bag member

, and the bag member 10 is airtightly stored in a bag (not illustrated) made of a non

breathable material. When the nasal congestion reliever 1 is used, the bag member 10

is taken out from the bag, and may be attached and fixed on the front side sheet member

6 with the peeling member peeled.

EXAMPLE 1

[0038]

The inventor of the present application evaluated the exothermic temperature of the chemical exothermic composition 4 in relation to the nasal congestion reliever 1 according to the present invention.

[0039]

A sample S used for the evaluation is different from the above embodiment

(see Fig. 1), as illustrated in Fig. 4, in that it includes one storage part 2 storing the

chemical exothermic composition 4, and does not include the connection part 3 and the

elastic member 5. The other points are the same as those in the above embodiment.

Thus, the same components are denoted by the same reference numerals, and detailed

description thereof will be omitted. The evaluation was performed with the peeling

member 9 peeled off and the sample S placed in the measuring device using the

adhesive layer 8.

[0040]

As the chemical exothermic composition 4, a tableted product of a cylindrical

shape was used. The tableted product had a weight of 1 g, a diameter of 15 mm, and a

height of 5 mm. The components of the chemical exothermic composition 4 included

to 40% by weight of iron powder, 1 to 5% by weight of salt, 20 to 30% by weight of

water, I to 5% by weight of activated carbon powder, 10 to 20% by weight of a water

retention material, and 10 to 20% by weight of a temperature control agent.

[0041]

The moisture permeability of the front side sheet member 6 and the back side

sheet member 7 was 8,000 g/(m 2 -24h).

[0042]

Using the temperature measurement sensor ST-22E-005-TS3-WT4

(manufactured by Adachi Keiki Co., Ltd.) and the graphic recorder KR2S2P-NOA

(manufactured by Chino Corporation), the exothermic temperatures (temperature on the skin side) of 10 samples S were measured. As the exothermic characteristics, the rise time (time required for the temperature to rise from 31.5°C to 39.9°C in this example), maximum temperature, and duration (during which the temperature is 40°C or higher) were measured. The results are illustrated in Fig. 5. Fig. 6 illustrates the exothermic temperature relative to time indicated by an average value of the 10 samples S.

[0043]

As can be seen in Fig. 5, the rise time of each sample S is within 40 seconds.

Furthermore, as can be seen in Fig. 6, the time required to reach the maximum

temperature is within 5 minutes. These times are much shorter than those with general

chemical body warmers. This result is considered to be obtained because of a swift

temperature rise of the chemical exothermic composition swiftly coming into contact

with air, due to a large value (8,000 g/(m 2 -24h)) of the moisture permeability of the

nonwoven fabric forming the bag.

EXAMPLE 2

[0044]

The inventor of the present application further performed a sensory test in

relation to the nasal congestion reliever 1 according to the present invention.

[0045]

For this sensory test, the same type of samples S as that used in Example 1 was

used. The subjects were those who had a symptom of stuffy noses at bedtime, and 15

subjects participated in the test.

[0046]

The test was performed as follows. The sample S was mounted to each

subject's face "nasal passages", and a commercially available product ("Breathe Right"

(registered trademark/GlaxoSmithKline Consumer Healthcare Japan Co., Ltd.) was attached to the subject's nose. Thus, the sample S and the commercially available product correspond to the product of the present invention. For comparison, a test was also performed with the commercially available product mounted on the subject's nose, without mounting the sample S.

[0047]

The severity of stuffy noses was quantified by the subjects using "Visual

Analog Scale (VAS)", with 0.00 indicating a state where the nose was not stuffed at all,

and 1.00 indicating a state where the nose was completely stuffed.

[0048]

The severity of the stuffy nose immediately before the mounting, and 5 and 10

minutes after the mounting was quantified in each of a case where breathing was

performed using both nostrils, a case where breathing was performed using the left

nostril only, and a case where breathing was performed using the right nostril only.

For the cases where the breathing is performed using one nostril only, the respective

nostrils on both sides were distinguished from each other, not as left and right nostrils,

but as a more stuffed nostril and a less stuffed nostril.

[0049]

The test results were processed as follows. As a value indicating how much

the stuffy nose was relieved, a value was calculated by subtracting the value

immediately before mounting from the value after 5 minutes/10 minutes. Whena

negative value is obtained as the calculated value, a larger absolute value thereof

indicates that the stuffy nose is more improved. Figs. 7 to 9 illustrate graphs of the

average values of the calculated value. Fig. 7 illustrates the case of breathing through

both nostrils, Fig. 8 illustrates the case of breathing through only one nostril that is more

stuffed, and Fig. 9 illustrates the case of breathing through only one nostril that is less stuffed. In each of the figures, a solid line indicates a case where the sample S and the commercially available product are both used, and a dotted line indicates a case where only the commercially available product is used.

[0050]

As can be seen in Figs. 7 to 9, when the sample S and the commercially

available product are both used, the stuffy nose is relieved in any of the cases of

breathing through both nostrils, the case of breathing through only one nostril that is

more stuffed, the case of breathing through only one nostril that is less stuffed. As can

be seen in Fig. 8, the stuffy nose is particularly relieved in the case of breathing through

only one nostril that is more stuffed, compared with the case where only the

commercially available product is used.
