Further, since the notch hole 14 and the stopper piece 42 are formed in an arc shape so that the container base 2 is prevented from rotating with respect to the base 41, it is easy to screw the contents storage portion 3 into the container base 2. Can be done. Therefore, by using the jig 40, it is possible to easily and surely perform the work of mounting the content storage portion 3 on the container base portion 2.

Next, a method of using the feeding container 1 having the above configuration will be described.

When using the feeding container 1, as shown in FIG. 8, the cap 4 is removed from the container base 2 to expose the content storage unit 3, and the seal body 24 is removed from the content storage unit 3 to expose the storage cylinder. Open body 21.

Next, as shown in FIG. 9, the storage cylinder 21 is rotated in the screwing direction with respect to the container base 2, and the storage cylinder 21 is moved relative to the container base 2 in the axial direction toward the base end side. .. At this time, the storage cylinder 21 is strongly rotated with respect to the container base 2 in the screwing direction so that the engaging protrusion 21b provided on the storage cylinder 21 gets over the locking protrusion 12f provided on the support 12. It is possible to prevent the storage cylinder 21 from unexpectedly rotating with respect to the container base 2 and breaking the thin portion 23 due to the resistance when the engaging protrusion 21b gets over the locking protrusion 12f.

When the storage cylinder 21 moves relative to the base end side in the axial direction while rotating relative to the container base portion 2 in the screwing direction, the middle plate 22 is supported by the support body 12 and is supported by the support body 12 to the base end side with respect to the container base portion 2. Since the relative movement in the axial direction toward the center is regulated, the storage cylinder 21 also moves relative to the middle plate 22 in the axial direction toward the base end side. As a result, the thin portion 23 connecting the storage cylinder 21 and the middle plate 22 is stretched in the axial direction and broken, and the middle plate 22 is separated from the storage cylinder 21. In this way, the inner plate 22 can be separated from the storage cylinder 21 by rotating the storage cylinder 21 with respect to the container base 2 in the screwing direction.

In the present embodiment, the ratchet mechanism 26 is provided between the inner plate 22 and the support 12 to prevent the inner plate 22 from rotating in the screwing direction with respect to the support 12, so that the container base 2 is used. When the storage cylinder 21 is rotated in the screwing direction, the storage cylinder 21 can be relatively rotated while being relatively moved in the axial direction with respect to the inner plate 22. As a result, when the storage cylinder 21 is rotated in the screwing direction with respect to the container base 2, the thin-walled portion 23 is stretched in the axial direction and threaded in the rotational direction, so that the thin-walled portion 23 is more easily broken. Can be made to.

After the middle plate 22 is separated from the storage cylinder 21, the storage cylinder 21 is further rotated in the screwing direction with respect to the container base 2, so that the middle plate 22 separated from the storage cylinder 21 is transferred to the storage cylinder 21. On the other hand, the solid content 25 can be fed out from the storage cylinder 21 and protruded outward from the open end of the storage cylinder 21 by relatively moving toward the tip side in the axial direction. Then, the solid content 25 can be applied to the object to be coated by bringing the solid content 25 protruding from the open end of the storage cylinder 21 into contact with the object to be coated.

Further, by rotating the storage cylinder 21 with respect to the container base 2 in the screwing direction or the opposite direction in accordance with the decrease of the solid content 25 due to use, the open end of the storage cylinder 21 of the solid content 25 The amount of protrusion from can be adjusted.

Further, after use, the storage cylinder 21 can be rotated with respect to the container base 2 in the screwing direction to store the solid content 25 inside the storage cylinder 21. Then, by attaching the cap 4 to the container base 2, the feeding container 1 can be carried without exposing the solid content 25 to the outside.

In the present embodiment, the inner diameter of the storage cylinder 21 is slightly larger on the tip side than the connecting portion where the middle plate 22 is connected by the thin-walled portion 23 and on the base end side of the connecting portion. Has been done. As a result, the thin-walled portion 23 broken inside the storage cylinder 21 is prevented from excessively sliding into the inner peripheral surface of the storage cylinder 21, and the inner plate 22 separated from the storage cylinder 21 is stored. It can be smoothly moved relative to 21 in the axial direction.

As shown in FIG. 10, the inner plate 22 is screwed into the storage cylinder 21 with respect to the container base 2 until the end on the base end side abuts on the connecting bottom wall portion 13. All the solid contents 25 can be projected from the storage cylinder 21 by being positioned at the open end of the 21.

As shown in FIG. 11, the used content storage unit 3 in which all the solid contents 25 are used keeps the storage cylinder 21 in the container base 2 until the screw connection between the female screw 11a and the male screw 21a is released. On the other hand, it can be removed from the container base 2 by rotating it in a direction opposite to the screwing direction.

The middle plate 22 is separated from the storage cylinder 21 and is held by the support 12 by undercut engagement. However, when the storage cylinder 21 is removed from the container base 2, the inner circumference of the storage cylinder 21 is formed. By engaging the locking portion 21c provided on the surface with the lower surface of the inner plate 22 facing the base end side, the inner plate 22 is moved to the side of the storage cylinder 21 and the storage cylinder is as shown in FIG. It can be removed from the container base 2 together with the body 21. By providing the locking portion 21c on the inner peripheral surface of the storage cylinder 21 in this way, the inner plate 22 separated from the storage cylinder 21 can be easily transferred to the storage cylinder 21 together with the storage cylinder 21. Can be removed from the container base 2. This makes it possible to facilitate the work of replacing the content storage unit 3 with respect to the container base 2.

In particular, in the present embodiment, each of the inner peripheral surfaces of the storage cylinder 21 is formed in a plate shape and abuts on the outer peripheral surface of the small diameter portion 12c of the support 12 in an inclined posture toward the side of the middle plate 22. Since a plurality of locking portions 21c are provided so as to be arranged at equal intervals in the circumferential direction, the middle plate 22 can be firmly and evenly supported in the circumferential direction by each of the locking portions 21c.
