As shown in FIG. 1, the holding portion 12 of the case cylinder 10 holds the operating member 30 so as to be relatively rotatable by being arranged between the upper end surface of the plurality of elastic pieces 52 and the stepped surface 62a of the outer cylinder 60. is doing. Further, a portion located below the holding portion 12 in the case cylinder 10, that is, the lower end of the case cylinder 10 is arranged between the enlarged inner peripheral surface 52c of each elastic piece 52 and the outer peripheral surface of the screw shaft 22. Has been done.

In the state shown in FIG. 1, which is the state before the contents 2 are fed out, the guide portion 14 of the case cylinder 10 is located at the upper end of the screw intermittent portion 22b of the screw shaft 22. At this time, the lower end surface of the feeding member 20 is located near the upper surface of the bottom wall 51b of the screw cylinder 50.

The feeding container 1 extends through the inside of the operating member 30 and the screw shaft 22 to the inside of the content support portion 21, and has a nozzle insertion path P into which a hollow rod-shaped filling nozzle described later can be inserted. That is, the nozzle insertion path P is partitioned by the inner peripheral surface of the bottom wall 51b of the screw cylinder 50 and the inner peripheral surface of the screw shaft 22. The lower end of the nozzle insertion path P may be closed by attaching a label to the lower surface of the bottom wall 51b of the screw cylinder 50.

As shown by the alternate long and short dash line in FIG. 1, the overcap 40 has a ridged cylinder having a peripheral wall portion 41 and a top wall portion 42, and is detachably attached to the outer cylinder 60 to be attached to the outer cylinder 60. It is configured to cover the feeding port 11 of the case cylinder 10. In the state shown in FIG. 1 in which the overcap 40 is attached to the outer cylinder 60, the inner peripheral surface of the peripheral wall portion 41 fits into the outer peripheral surface of the reduced diameter portion 63 of the outer cylinder 60, and the lower end surface of the peripheral wall portion 41 is formed. It is in contact with the upper surface of the step portion 62 of the outer cylinder 60.

As shown in FIG. 9, in the feeding container 1 of the present embodiment having the above configuration, with the overcap 40 removed, the operating member 30 is held by one hand or the like while holding the case cylinder 10 by the other hand or the like. By gripping the grip portion 65 and rotating it to one side in the circumferential direction to rotate the operating member 30 relative to one side in the circumferential direction with respect to the case cylinder 10, the contents 2 can be extended to the feeding port of the case cylinder 10. It can be extended to the outside from 11.

That is, when the operating member 30 is rotated relative to one side in the circumferential direction with respect to the case cylinder 10, the screwed portion 52a, which is a part of the operating member 30, rotates relative to one side in the circumferential direction with respect to the case cylinder 10. Since the screw shaft 22 provided with the male screw 22a to be screwed into the screw portion 52a is stopped by the case cylinder 10, when the operating member 30 is rotated relative to the case cylinder 10 in the circumferential direction, the screw shaft 22 is screwed. The screw shaft 22 rises integrally with the content support portion 21 with respect to the case cylinder 10 due to the screwing action of the joint portion 52a and the male screw 22a. As a result, the content 2 is pushed up by the ascending content support portion 21 and is fed out from the feeding port 11 to the outside of the case cylinder 10. The amount of extension (protrusion amount) of the content 2 from the case cylinder 10 can be adjusted by the amount of relative rotation of the operating member 30. Therefore, by rotating the operating member 30 relative to one side in the circumferential direction by a desired amount with respect to the case cylinder 10, a desired amount of the content 2 is fed out from the feeding port 11 of the case cylinder 10 and used. Can be done.

Further, when the operating member 30 is relatively rotated with respect to the case cylinder 10 toward the other side in the circumferential direction opposite to that when the content 2 is unwound, the screw shaft 22 is screwed by the screwing action of the screw portion 52a and the male screw 22a. Is lowered with respect to the case cylinder 10 integrally with the content support portion 21. As a result, the content 2 is pulled down by the descending content support portion 21 and is fed into the inside of the case cylinder 10 from the feeding port 11. Therefore, after the content 2 is applied, the content 2 can be fed into the case cylinder 10 and the content 2 can be protected by the case cylinder 10. Further, when the content 2 is extended too much, the content 2 can be extended to adjust the amount of extension from the case cylinder 10.

When the feeding member 20 is operated in the vertical direction in response to the rotation operation to the operating member 30, an appropriate sliding resistance is given between the case cylinder 10 and the feeding member 20 by the sliding resistance portion 16. By providing the sliding resistance portion 16 in this way, it is possible to easily set an appropriate resistance for the operation of the feeding member 20 in response to the rotation operation on the operating member 30.

As shown in FIG. 9, when the content 2 is extended to the maximum amount, the screwed portion 52a reaches the inside of the retaining portion 23 of the screw shaft 22, and the screwed portion 52a and the male screw 22a are unscrewed. Even if the operating member 30 is further rotated relative to one side in the circumferential direction with respect to the case cylinder 10, the screw shaft 22 does not rise any further, whereby the feeding member 20 is ejected from the feeding port 11 of the case cylinder 10. It is prevented from falling out.

The feeding container 1 of the present embodiment can be assembled, for example, as shown in FIGS. 10 to 13.

First, as shown in FIG. 10, the feeding member 20 is attached to the jig 3. The jig 3 has a disk-shaped pedestal 3b whose bottom surface 3a is a mounting surface, and a columnar shaft portion 3c whose diameter is reduced from that of the pedestal 3b and extends upward from the upper surface of the pedestal 3b. Further, the shaft portion 3c has a stepped portion 3d whose diameter is reduced in a stepped shape toward the upper side. Therefore, by assembling the feeding member 20 in the inverted posture to the jig 3 in the upright posture from above and bringing the step portion 24 of the feeding member 20 into contact with the stepped portion 3d of the jig 3, the feeding member is brought into contact with the jig 3. 20 can be attached.

Next, as shown in FIG. 11, the case cylinder 10 in the inverted posture is assembled from above. Specifically, the case cylinder 10 is brought into contact with the upper end (the lower end in the vertical direction at the time of this assembly) of the vertical groove 22c constituting the screw intermittent portion 22b of the feeding member 20 by bringing the guide portion 14 of the case cylinder 10 into contact with the case cylinder 10. Can be assembled.

Then, as shown in FIG. 12, the screw cylinder 50 in the inverted posture is assembled from above. The screw cylinder 50 has a screw portion 52a to be screwed with the male screw 22a of the screw shaft 22, and each screw portion 52a is displaced in the radial direction due to the elastic deformation of the elastic piece 52, and the male screw 22a Can be unscrewed to. Therefore, the upper end surface of the elastic piece 52 (the lower end surface in the vertical direction at the time of this assembly) becomes the enlarged diameter portion 13 (holding portion 12) of the case cylinder 10 by simply pushing down the screw cylinder 50 straight without rotating it downward. The screw cylinder 50 can be pushed down until it comes into contact with the screw cylinder 50 to complete the assembly of the screw cylinder 50.

Then, as shown in FIG. 13, the jig 3 is removed, the assembled product is placed in an upright posture, and then the exterior cylinder 60 in the upright posture is assembled from above. Specifically, the exterior cylinder 60 can be assembled by bringing the stepped surface 62a of the exterior cylinder 60 into contact with the upper surface of the enlarged diameter portion 13 (holding portion 12) of the case cylinder 10. By this assembly, the outer cylinder 60 is fitted to the fitting guide portion 51d of the screw cylinder main body 51 and the fitting surface 51f, and is integrated with the screw cylinder main body 51. At that time, the outer cylinder 60 first slides downward on the fitting guide portion 51d as it descends, but the sliding resistance is suppressed because the fitting guide portion 51d is composed of a plurality of convex ribs 51c. Therefore, the outer cylinder 60 can be smoothly lowered and fitted to the fitting surface 51f.

By assembling the outer cylinder 60, the elastic piece 52 abuts on the support surface 64 of the outer cylinder 60 via the protrusion 52d and is supported from the outside in the radial direction. As a result, the elastic piece 52 is elastically deformed outward in the radial direction to prevent the screwed portion 52a and the male screw 22a from being unscrewed.

When the feeding container 1 is assembled in this way, the content 2 is filled inside the content supporting portion 21 and the portion above the case cylinder 10 before the overcap 40 is attached. This filling step can be performed, for example, as follows.

First, the feeding port 11 is closed with a cap body (not shown), and the feeding container 1 is placed in an inverted posture. Next, a hollow rod-shaped filling nozzle (not shown) is inserted into the nozzle insertion path P from vertically above. Then, in a state where the discharge port of the filling nozzle is located in, for example, the content support portion 21, the content 2 in a high temperature state having fluidity is discharged, and the content support portion 21 and the case cylinder 10 are above (vertically). Fill the inside with the lower) part. After that, the content 2 is cooled and solidified, and the cap body is removed.

Since the feeding container 1 of the present embodiment has a configuration in which the feeding member 20 and the operating member 30 are screwed together without passing through the case cylinder 10, it is possible to easily realize the miniaturization of the feeding container 1 in the radial direction. .. Further, the feeding container 1 of the present embodiment has a configuration in which a plurality of elastic pieces 52 can be elastically deformed in the radial direction at the time of assembly to remove the screwing portion 52a from the male screw 22a. Easy assembly can be realized by assembling the cylinder 50 straight without rotating it.

The feeding container 1 of the present embodiment described above has a nozzle insertion path P to enable back filling in which the contents 2 are filled not from the side of the feeding port 11 but from the lower side on the opposite side thereof. Not limited to this, for example, as in the modified example shown in FIG. 14, the content support portion 21 has the bottom wall 21a and therefore does not have the nozzle insertion path P, and the content 2 is fed out. It may be configured to be filled from the side of 11. In FIG. 14, the same reference numerals are given to the elements corresponding to the elements shown in FIGS. 1 to 13.

Further, in the feeding container 1 of the first embodiment, the holding portion 12 is composed of a diameter-expanded portion 13 having a U-shaped vertical cross-sectional shape over the entire circumference, and each guide portion 14 is composed of a vertical rib 15. However, the holding portion 12 and each of the guide portions 14 may be configured as in the second embodiment shown in FIGS. 15 to 19. In FIGS. 15 to 19, the same reference numerals are given to the elements corresponding to the elements shown in FIGS. 1 to 13.

In the second embodiment, as shown in FIG. 15, the outer cylinder 60 and the overcap 40 are each made of synthetic resin, but have the same configuration as that of the first embodiment in other respects. Further, as shown in FIGS. 15 and 18 (a) to 18 (c), the feeding member 20 has the same configuration as that of the first embodiment. In the present embodiment, the widths of the two screw intermittent portions 22b are different from each other in the circumferential direction, and the widths of the two guide portions 14 are also different from each other in the circumferential direction (see FIG. 17). However, the widths of the two screw intermittent portions 22b and the two guide portions 14 may be the same as each other. By making the widths different as described above, it is possible to prevent erroneous assembly in which the inclined surface of the upper end portion does not match when assembling the case cylinder 10 and the feeding member 20. It should be noted that the first embodiment may also have a configuration in which the widths are different as in the present embodiment. Further, the screw cylinder 50 has the same configuration as that of the first embodiment. The case cylinder 10 has the same configuration as that of the first embodiment except for the holding portion 12 and the two guide portions 14.

As shown in FIGS. 15 to 17, in the present embodiment, the holding portion 12 is provided at the lower end of the case cylinder 10. The holding portion 12 is composed of a diameter-expanded portion 13 having an expanded diameter on the outer peripheral surface of the case cylinder 10. In the present embodiment, the inner peripheral surface of the enlarged diameter portion 13 has the same inner diameter as the inner peripheral surface of the case cylinder 10 above the enlarged diameter portion 13 except for the lower portion, and the diameter is expanded at the lower portion. There is. Further, a plurality of recesses 13d arranged intermittently in the circumferential direction are provided on the upper portion of the outer peripheral surface of the enlarged diameter portion 13. At the lower part of the outer peripheral surface of the enlarged diameter portion 13, a plurality of protrusions 13e arranged intermittently in the circumferential direction are provided.
