Further, as shown in FIGS. 2 and 3A, an annular groove 63 </ b> A having an annular shape in plan view is formed in the center portion of the bottom sheet material 63. The annular groove portion 63 </ b> A is formed in a rib shape in which the inner surface side of the refill container 60 is a convex portion and the outer surface side is a concave portion, and the inner diameter thereof is substantially equal to the outer diameter of the fracture cylinder 44. In addition, instead of the annular groove portion 63A, a circular concave portion 63B having a circular shape in a plan view may be formed in the central portion of the bottom sheet material 63 as shown in FIG.
In this way, the refill container 60 is formed in a bag shape, and contains liquid refill contents.

Next, a method for refilling contents with the dispensing cap 1 having the above-described configuration will be described.
First, the screwing of the second male screw portion 41B and the second female screw portion 52A is released, the sub cap portion 32 is removed from the main cap portion 31, and the broken cylinder 44 is exposed.
Then, as shown in FIGS. 3A and 4, the upper edge of the broken cylinder 44 is brought into contact with the bottom sheet material 63 of the refill container 60. At this time, the front upper edge of the broken cylinder 44 is brought into contact with the annular groove 63A, thereby positioning the broken cylinder 44 with respect to the bottom sheet material 63.

  Subsequently, as shown in FIG. 5, the broken cylinder 44 is pierced into the bottom sheet material 63. That is, by pushing the broken cylinder 44 against the bottom sheet material 63, the bottom sheet material 63 is broken, and the broken cylinder 44 enters the inside of the refill container 60. At this time, since the upper end of the fracture cylinder 44 is positioned with respect to the bottom sheet material 63 by the annular groove 63A, the fracture cylinder 44 can be stably entered into the bottom sheet material 63. Thereby, the refill container 60 is opened, and the liquid content accommodated in the refill container 60 flows into the main cap portion 31 through the broken cylinder 44. In addition, the contents dripping along the outer peripheral surface of the broken cylinder 44 flows into the main cap portion 31 through the communication port 41A. Therefore, it is not necessary to incline the container 2 and the refill container 60 after the broken cylinder 44 has entered the refill container 60.

Then, the contents flowing into the main cap portion 31 flow into the container 2 through the inside of the extraction tube portion 21 and the hole portion 27A. At this time, even if liquid splash occurs in the main body cylinder 41 by bringing the upper end of the main body cylinder 41 into contact with the bottom sheet material 63, the contents are not scattered outside the main body cylinder 41. Further, the contents staying in the bottom wall portion 27 are collected in the container 2 through the slit 21B or the hole portion 27A. In this way, the contents stored in the refill container 60 are filled into the container 2.
Thereafter, the sub cap portion 32 is screwed onto the main cap portion 31 and attached.
As described above, the contents are refilled into the container.

Next, a method for measuring and dispensing the contents with the above-described dispensing cap 1 will be described.
First, in a state where the second male screw portion 41B and the second female screw portion 52A are screwed together, the screwing of the first male screw portion 25A and the first female screw portion 43A is released, and the overcap 12 (The main cap part 31 and the sub cap part 32) are removed from the cap main body 11, and the extraction | pouring cylinder part 21 is exposed. Then, the overcap 12 is turned upside down, and the container 2 is tilted in a state where the front side surface of the dispensing cylinder portion 21 is in contact with the opening end of the main body cylinder 41. As a result, the contents of the container 2 are poured out from the dispensing cylinder portion 21 into the main cap portion 31. The content poured into the main cap portion 31 flows into the sub cap portion 32 through the communication port 41 </ b> A and the broken cylinder 44. In this way, the contents of the container 2 are weighed by the predetermined amount by the main cap portion 31 and the sub cap portion 32.

Thereafter, the container 2 is raised, and the main cap portion 31 and the sub cap portion 32 into which the contents are poured are tilted to pour out the contents. At this time, since the communication port 41 </ b> A is formed in the main cap portion 31, the contents are poured out through not only the broken cylinder 44 but also the communication port 41 </ b> A.
As described above, a predetermined amount of content is weighed and dispensed. Note that only the sub cap portion 32 may be removed and the sub cap portion 32 may be weighed.

  According to the pouring cap 1 having the above-described configuration, the contents in the refill container 60 are filled into the container 2 through the broken tube 44 that has entered the refill container 60 simultaneously with opening without tilting the refill container 60. Therefore, the contents in the refill container 60 are prevented from spilling during the refilling operation.

  Next, a second embodiment of the dispensing cap according to the present invention will be described based on the drawings. The embodiment described here has the same basic configuration as the first embodiment described above, and is obtained by adding another element to the first embodiment described above. Therefore, in FIG. 6, the same components as those in FIGS. 1 to 5 are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 6, the dispensing cap 100 according to the second embodiment has a saw-blade uneven portion 102 formed at the upper end edge of the broken cylinder 101.

  The dispensing cap 1 having the above-described configuration also has the same effect as described above, but the saw blade-shaped upper end edge is refilled by forming the saw blade-shaped uneven portion 102 on the upper end edge of the broken cylinder 101. Since the upper end edge of the broken cylinder 44 can apply a larger pressure to the refill container 60 by abutting against the container 60, the refill container 60 can be broken more easily and the broken cylinder 101 can be pierced.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, although the communication port is formed in the main cap part, the content poured into the sub cap part through only the broken cylinder without forming the communication port is poured into the outside of the main cap part. It is good also as a structure.
The sub cap portion is detachably screwed to the main cap portion, but can be attached to and detached from the main cap portion by other configurations such as a configuration in which the main cap portion is hinged to be freely opened and closed. It may be attached freely.
Furthermore, the upper end shape of the broken cylinder is not limited to the shape in which the front side is located above the rear side and gradually inclines toward the rear side as long as the refill container can be stabbed and entered, and other shapes It may be.
Moreover, a fracture | rupture part is not restricted to a cylinder shape, Other shapes, such as columnar shape, may be sufficient.

The refill container is not limited to a flexible bag, but may be any container that can open the spout of the refill container by breaking the seal portion or the closing plate, such as a tube container or a blow bottle. Etc. may be adopted. Moreover, you may employ | adopt the container which does not have flexibility as a refill container.
In addition, the bottom sheet material of the refill container has an annular groove or a circular recess, but it can be formed if the upper edge of the broken cylinder can be positioned stably when breaking through the bottom sheet material of the refill container with the broken cylinder. It does not have to be.

  According to the present invention, industrial applicability is recognized with respect to a dispensing cap that is difficult to spill contents during a refilling operation of the content and can easily perform the refilling operation of the content.
