[Means for Solving the Problems] The results of intensive studies aimed at reducing the discomfort and effectively spraying the drug and the washing solution into the nasal cavity when administering the drug into the nasal cavity and washing the nasal cavity. It has been found that by inclining the spout in accordance with the inclination angle of the nasal cavity of a person and by providing a stopper, a shape in which the medicinal solution or washing liquid sprayed into the nasal cavity does not easily flow down from the nasal cavity is effective. Things. Therefore, in the present invention, with respect to a spout device provided at the tip of a dispenser for ejecting a low-viscosity liquid contained in a container, the center axis of the tip of the spout is at a predetermined angle with respect to the container axis, preferably 15 °. It has an inclination angle of ~ 45 °, and a stopper is installed at the tip of the spout, and when used, the spout tip is inserted into the nasal cavity, and the stopper is used to close the nasal cavity or used without blocking In such a case, the plate is formed in a reflection plate shape so that the liquid after washing does not reach hands or containers.

According to the inventor's knowledge, when the tip of the spout inserted into the nasal cavity is at 0 to 15 ° with respect to the center axis of the container, the liquid directly drips on the finger pressing the injection button, and the angle larger than 45 ° is formed. If so, the bottle must be used inverted. Therefore, this insertion part can be up to 20-45 °, preferably 25-
It is desirable to have a tilt angle of 40 °.

Therefore, according to the present invention, when administering a drug into the nasal cavity and washing the nasal cavity, discomfort can be further reduced, and the drug and the washing solution can be efficiently sprayed into the nostrils. Further, in the present invention, in order to efficiently clean dirt in the blocked nasal cavity, the viscosity of the cleaning liquid is 1.3.

The reasons for the structure relating to the spout and the stopper will be described. In order to devise a method for directly preventing dripping or splashing of the preparation, the shape around the nasal cavity of 30 adult men and women was measured. The result is shown in FIG. From the results in FIG. 1, the spout has a long diameter of 11 to 17 mm, preferably 1 to 17 mm.
A stopper formed into a roughly circular shape of 3 to 15 mm or a roughly polygonal shape or an irregular shape having a contact point in the circle is attached to the tip of the spout, and the spout tip is inserted into the nasal cavity when used. It has turned out that it is preferable to form the nasal cavity with a stopper. It has been found that spraying or injecting the preparation into the nasal cavity while the nasal cavity is closed with the stopper is very effective for efficient drug administration or cleaning.

Then, the inventor conducted a palatability survey on the tip of the spout to be inserted into the nasal cavity as shown in FIG. This is a study of the preference of the length of insertion into a nostril when a nozzle having a diameter of 7 mm without a stopper was actually used in 30 adult men and women. In addition, the user of nasal drops tended to insert deeply. In addition, as shown in FIG. 3, the preference of the spout for the thickness of the tip was also investigated. This survey was conducted on 37 adult males and females to investigate their preference for the diameter when the spout nozzle was actually used. From the preference survey of the adults in FIGS. 2 and 3, there is no sense of fear as the tip, and
Regarding the size that can be inserted into the nasal cavity, the outer diameter of the tip of the spout is preferably 2 mm to 10 mm, more preferably 6 to 8 mm, and the distance from the tip to the stopper. From the above-mentioned investigation, a was found to be good if 0 mm to 20 mm, and more preferably 9 to 17 mm.

Further, as shown in FIG. 4, the preference of the spout for the inclination angle of the spout was examined for 30 adult men and women. From the results of FIG. 4, the evaluation that it is difficult to use at an angle exceeding 0 ° to 15 ° and 45 ° exceeds the evaluation that it is easy to use, and the evaluation that it is easy to use within the range of 15 ° to 45 ° is many.
