It may be present outside the accommodation bag.

  More specifically, when the refreshing agent is contained in the nasal passage improving tool of the present invention, for example, the refreshing agent may be mixed with each compounding component of the exothermic composition and stored in a storage bag. The cooling agent may be contained in at least a part of the bag for the exothermic composition, and the cooling agent may be preliminarily contained in another sheet or an optional adhesive component, or may be separately breathable. The sheet, the adhesive component, the storage bag, or the like may be disposed inside and / or outside the storage bag for the exothermic composition.

  In the case where the refreshing agent is mixed with each compounding component in the exothermic composition, for example, the refreshing agent itself may be mixed with each compounding component, and it is cooled with water or the like using a surfactant or the like. The mixture obtained by mixing the agent may be mixed with each of the above ingredients, and the encapsulated microcapsule obtained by previously encapsulating a cooling agent or such mixture in a conventionally known microcapsule.

The nasal passage improvement tool is also useful in relieving discomfort around the nose, such as the throat passage. From this viewpoint, it can be said that the present invention provides, for example, a nasal passage and a throat passage improvement tool.

  As described above, the nasal passage improving tool of the present invention contains an oxidation accelerator having an iodine adsorption performance of 500 mg / g or less, particularly in the exothermic composition. Can be suppressed and prevented. For this reason, as long as the nasal passage improvement device is stored in an environment in which contact with oxygen is hindered, it is possible to suppress and prevent the loss of the dissipating property of the cooling agent during storage. Even after storage, it can exhibit an excellent cooling effect derived from a cooling agent during use and can exhibit a comfortable thermal effect. Therefore, according to the nasal passage improving tool of the present invention, the nasal passage feeling is improved even after being stored for a long period of time, and discomfort such as nasal congestion and runny nose can be reduced and eliminated.

(2) Evaluation of the maximum temperature, duration of heat generation, and average temperature Each of the manufactured nose passage improvement devices and comparative products was left at 20 ° C. in the presence of oxygen for 24 hours, and then each outer bag was opened to open each nose passage. The improvement tool and the comparative product were taken out and evaluated for maximum temperature, exothermic duration, and average temperature. Specifically, a nasal passage improvement tool in which a predetermined underlay material (but without a covering material) is stacked on the thermal part defined in JIS S4100 (2007), and left in the same atmosphere as the ambient temperature for 2 hours or more. After the heat is generated based on the usage method, the maximum temperature and the heat generation duration are measured by measuring the time from the start of heat generation to the predetermined temperature exceeding the predetermined temperature and reaching the predetermined temperature according to the predetermined method. The average temperature was evaluated. The exothermic duration was evaluated as the time for maintaining a temperature of 34 ° C. or higher. The average temperature is an average value for 6 hours after the temperature exceeds 34 ° C. after the start of heat generation.

  As is apparent from Table 1, all the maximum temperatures showed desired values. On the other hand, the duration of the nasal passage improvement tools 1 to 4 showed a sufficient duration of 5 hours or more, but the comparative product 1 was less than 5 hours. The average temperature was less than 42 ° C. for the nasal improvers 1 to 4 and desirable values, whereas the comparative product 1 was as high as 46 ° C. or higher, which was too hot for long-term use, especially for long-term use at bedtime. It became.

Example 2
For the nasal passage improvement tool 2 and the comparative product 1 manufactured in Example 1 (however, the storage bag uses an air permeability measured based on JIS P8117 of 15 seconds / 300 cc), the temperature change over time, the cool feeling The body temperature was evaluated.

  Specifically, the temperature change over time was evaluated as follows. In the same manner as in Example 1, according to JIS S4100 (2007) (but without a coating material), the temperature change over time was evaluated by measuring the heat generation 6 hours after the start of heat generation.

Moreover, the cool feeling and the body temperature were evaluated as follows. After manufacturing and leaving as above, the outer bag was opened, the nose passage improving device and the comparative product were taken out, and the refreshing feeling and body temperature derived from the nose passage improving device or the comparative product were evaluated. Specifically, four test subjects were allowed to wear a nasal passage improvement tool taken out from the outer bag around the neck, and the refreshing sensation and body temperature after 30 minutes, 2 hours, and 6 hours were 1 to 5 described later. Evaluation was made in 5 stages. The larger the value of the refreshing feeling, the better the evaluation, which means that a preferable refreshing feeling is obtained. The sensory temperature indicates that the larger the value is, the higher the temperature is, and the smaller the value is, the more the sensory temperature is, and the evaluation value 3 means that the most preferable sensory temperature is obtained.

Further, as apparent from Table 2, in Comparative Product 1, no refreshing feeling was obtained in any of 6 hours after the start of use immediately after the start of use. Further, as is apparent from Table 3, the comparative product 1 tended to feel that it was slightly hot immediately after the start of use until at least 2 hours after the start of use. As is clear from this, in Comparative Product 1, there was a concern of burns due to high or low temperature due to the heat generation behavior, no refreshing feeling was obtained, and the effect of improving nose passage was insufficient.

  On the other hand, as is apparent from FIG. 7, the nose passage improving tool 2 rises to a moderately high temperature at the start of use, and then the temperature decreases earlier. Further, as is apparent from Table 2, in the nasal passage improver 2, not only immediately after the start of use but also 6 hours after the start of use, the desired refreshing feeling due to the refreshing agent was maintained. From this, it can be seen that in the nose passage improving device 2, the refreshing agent is effectively diffused at the start of use, and then the refreshing agent can be continuously diffused.

  In addition, in this way, the nasal passage improvement tool 2 rises to a moderately high temperature at the start of use and then rapidly decreases in temperature. An appropriate body temperature was always maintained without being too warm. From this, in the nose passage improving tool 2, a unique heat generation effect and a cooling effect are exhibited, so that a desired cooling feeling and body temperature can be obtained, and therefore the nose passage can be improved comfortably and effectively. I understood. In addition to this, not only the nasal passage but also the uncomfortable feeling around the nose, for example, the throat passage, can exhibit a desired refreshing sensation. It turned out that the effect which relieves pleasure can be exhibited.

  Moreover, according to such a nasal passage improvement tool 2, it turned out that a burn can be prevented even if it is a case where it is used for a long period of time by contacting with skin from the heat_generation | fever characteristic. For this reason, even when used at bedtime, for example, there is no fear of burns due to high or low temperatures, and it can be used with peace of mind in a wide range of generations, regardless of age, such as low and high age groups.

  Moreover, the nose passage improving tool 2 was not sticky and excellent in the feeling of use, and there was no worry that the skin and clothes would become dirty.
