As shown in FIG. 7 of the accompanying drawings, this cap is a cap that is mounted on the mouth tube portion 11 of a container 10 for containing a liquid substance, and has a plurality of pouring holes at the center of the cap body 20. A nozzle portion 22 having a nozzle 22a is provided, and a liquid reservoir groove 23 is provided around the nozzle portion 22.

The cap body 20 is shown in FIGS. 8 and 9 attached.
As also shown in FIG. 2, a cylindrical nozzle portion 22 is provided in the center of the top surface portion 21 and has a cylindrical shape with a lid.
The vicinity of the top end of 2 projects from the top surface portion 21 of the cap body 20. A liquid reservoir piece 24 having an L-shaped cross section is extended on the outer periphery of the nozzle portion 22, and a liquid reservoir groove 23 is formed in a ring shape by the outer periphery of the nozzle portion 22 and the liquid reservoir piece 24. The liquid reservoir groove 23 is connected to the top surface portion 21 of the cap body 20. The nozzle portion 22 is provided with a plurality of pouring holes 22a. The pouring hole 22a has an inner surface on the outer side of the cap body 20 (hereinafter referred to as an outer side surface) that is parallel to the axis X of the cap body 20 (hereinafter, this state is referred to as vertical). The inner surface on the inner side (hereinafter referred to as the inner side surface) is arranged to be separated from the axis X of the cap body 20 toward the tip. These pouring holes 22a
Are arranged circumferentially around the periphery of the top end surface of the nozzle portion 22, as shown in FIG. A cap lid 30 is connected to the cap body 20 via a hinge mechanism 40. The cap lid 30 is provided with an engagement ring 31 projecting at a position corresponding to the liquid reservoir groove 23.
When the cap body 20 is covered with 0, the engagement ring 31 engages with the liquid storage groove 23. Further, an internal thread 26 is formed on the inner wall of the cylindrical portion 25 of the cap body 20, and the internal thread 26 is formed on the inner tubular portion 11 of the container 10.
Is screwed with a male screw 12 formed on the outer periphery of the.

In the above-described cap, the inner side surface of the pouring hole 22a is shaped so as to be separated from the axis X of the cap body 20 as the tip end thereof, so that when the container 10 is squeezed, it is housed in the container 10. The contents are radially discharged from the pouring hole 22a. Further, when the container 10 is erected after the contents are discharged, the contents remaining attached to the nozzle portion 22 flow down along the outer peripheral wall of the nozzle portion 22, and the liquid storage groove 2
It is stored in 3. When the cap is tilted together with the container 10 in the next pouring operation, the content stored in the liquid storage groove 23 moves downward in the liquid storage groove 23 in the tilted state, and by the action of the surface tension. It is stopped and stays in the liquid storage groove 23, merges with the content from the pouring hole 22a, and is discharged.

In the cap as described above, it is desirable that the contents can be ejected as uniformly as possible. In order to uniformly discharge the contents, a method of providing a large number of pouring holes has been conventionally adopted. However, in the above-mentioned cap, the inner side surface of the pouring hole 22a is provided with the cap body 20.
The content is ejected in a wide range by being formed so as to be inclined with respect to the axis line X. In such a conventional cap, since the wall thickness of the nozzle portion 22 is thin near the inner side surface of the spout hole 22a, increasing the number of spout holes 22a reduces the strength against impact such as dropping. Further, in the conventional cap as described above, the pouring hole 22a is formed by providing the molding die with the protruding portion. In addition, the size of the pouring hole 22a cannot be made too small in order to avoid the damage of the protrusion. Therefore, when the number of the pouring holes 22a is increased, the momentum of the discharged contents is reduced, and the contents discharged from different pouring holes 22a join together,
The contents cannot be discharged uniformly. Also, when the momentum of the contents is reduced, the range of ejection is also narrowed. Therefore, in the conventional cap as described above, there is a limit in discharging the contents in a wide range and uniformly.

Therefore, an object of the present invention is to provide a cap capable of uniformly discharging the contents in a wide range.
