portions

26, 26 existing on both sides. The content liquid received by each receiving portion 26 is guided to the distal end side along the second portion 26b at the time of tilting, and is poured out during the subsequent measurement.

When refilling the contents, the measuring cap 102 is rotated in the direction opposite to that at the time of fastening, and the screwing of the female screw portion (not shown) of the measuring cap 102 and the male screw portion 17 of the nozzle cap 10 is released. The measuring cap 102 is removed from the nozzle cap 10. With the measuring cap 102 removed, the contents are refilled from the refill container into the container body 100A through the nozzle portion 13 of the nozzle cap 10.

In the conventional configuration, when the remaining amount of the contents in the container main body 100A decreases, the contents enter between the mouth portion 103 of the container main body 100A and the nozzle base portion 12 of the nozzle cap 10. Therefore, even if the container body 100A is tilted, the contents are not easily poured out from the nozzle cap 10, and the contents remain in the container body 100A and cannot be completely used up in many cases.

On the other hand, in the present embodiment, a concave guiding portion 28 that leads to the dispensing opening hole 23 is provided in a part of the first inclined surface 22A constituting the bottom surface portion 22, and the guiding portion 28 When the container body 100A is tilted at the time of use, the contents entering between the mouth part 101 of the container body 100A and the nozzle base part 12 inserted into the mouth part 101 are poured out by the guide part 28. It is guided to the opening hole 23 and can be poured out through the bowl-shaped portion 24.

The guiding portion 28 extends radially outward from the extraction opening hole 23, and becomes a deep recess that is further away from the one surface 22 B side as it is closer to the extraction opening hole 23. Further, the top portion Q side of the inner surface 28 a of the guide portion 28 extends in a direction intersecting the axis C, and is inclined with respect to the first inclined surface 22 A of the bottom surface portion 22. As a result, when the container body 100A is tilted, the contents accumulated below the dispensing opening hole 23 along the first inclined surface 22A enter the guide portion 28 that is recessed toward the nozzle portion 13 side. It becomes easy to enter. Therefore, even when the remaining amount of the contents in the container main body 100A is small, the contents are efficiently guided to the dispensing opening hole 23 without extremely increasing the tilt angle of the container main body 100A. Can be dispensed.

As described above, according to the nozzle cap 10 of the present embodiment, by providing the guide portion 28 at the lower position when tilted, the outflow of the contents accumulated between the container main body 100A can be improved. It is possible to reduce the residual liquid in the container body 100A and use the contents effectively.

In the present embodiment, the top Q side of the inner surface 28a of the guide portion 28 extends in a direction intersecting the axis C. However, the present invention is not limited to this. For example, the top portion Q side of the inner surface 28a The end portion may be inclined so as to be positioned in the + Z direction with respect to the end portion on the inner cylinder portion 21 side. That is, you may incline to the opposite side to 22 A of 1st inclined surfaces. Thereby, it can be made to flow out so that the contents by the side of container main part 100A may be scooped out.

Further, in the present embodiment, in each receiving portion 26, the second portion 26 B exposed to the outside of the fitting portion 11 is thinned while ensuring the function of collecting the remaining liquid in the first portion 26 A. The front end side of the bowl-shaped portion 24 is sometimes easy to see. Thereby, it is easy to pour the contents into the measuring cap 102. The residual liquid received in the second portion 26B is guided to the distal end side along the second portion 26b, and is poured into the measuring cap 102 together with the contents poured out from the bowl-shaped portion 24. Furthermore, since the second portion 26B is made thinner than the first portion 26A, the amount of resin to be used can be reduced, and weight reduction and cost reduction can be achieved. Further, the overall size of the nozzle cap 10 can be reduced.

The nozzle cap 10 of the present embodiment is a screw type, but is inserted and fitted into the mouth portion 101 of the container main body 100A so as not to come out upward due to, for example, press fitting, engagement of an undercut portion or the like. It is good also as a structure.

The preferred embodiments according to the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs to.

For example, the size and shape of the guiding portion 28 described above are not limited to those shown in the drawings, and can be changed as appropriate according to the type of contents.
