DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the rod-shaped object feeding container according to the present invention will be described below with reference to FIGS. The rod-shaped object feeding container 10 of the present embodiment mainly includes a rear cylinder 1
2, a middle cylinder 14 that is prevented from rotating with the rear cylinder 12 in the rear cylinder 12, and a female screw 14d formed on an inner peripheral surface of the middle cylinder 14.
A screw shaft 16 having a male screw 16b screwed to the front cylinder 18 and a front cylinder 18 rotatably connected to the rear cylinder 12 and the middle cylinder 14.
And a rod-shaped object receiving portion 24 for holding the rod-shaped object 22 and a cap 20.

As shown in FIG. 2, an annular groove 12a for connecting the front cylinder 18 so as to be axially immovable and relatively rotatable is formed at the front portion of the inner peripheral surface of the rear cylinder 12. A plurality of keyways 12b for preventing the rotation of the middle cylinder 14 are formed in the intermediate portion. on the other hand,
As shown in FIG. 3, a key 14a, which is a detent portion, is formed at the rear portion of the outer peripheral surface of the middle cylinder 14, and the key 14a fits into the key groove 12b. The relationship between the key groove and the key may be such that the key is formed on the inner peripheral surface of the rear cylinder 12 and the key groove is formed on the outer peripheral surface of the middle cylinder 14. Further, the front end of the key groove 12b and the key 14
Tapered surfaces 12c and 14b are respectively formed at the rear end of "a" in order to facilitate mutual fitting during assembly or the like.

An annular projection 14c is formed on the outer peripheral surface of the intermediate cylinder 14 to connect a later-described distal cylinder 18 so as to be axially immovable and relatively rotatable. A female screw 14d is formed in the portion. As shown in FIG. 4, the screw shaft 16 is formed with four vertical ribs 16a extending in the vertical direction so as to form a substantially cross shape when viewed from behind, and an external thread is provided on the outer surface of the vertical rib 16a. 16b is formed, and the male screw 16b is screwed into the female screw 14d.

The screw shaft 16 is assembled to the middle cylinder 14 by inserting the rear end of the screw shaft 16 from the front end of the middle cylinder 14. While screwing the male screw 16b into the female screw 14d, When the screw shaft 16 is inserted into the middle cylinder 14, the screw shaft 16 must be rotated, which takes time. However, in the present embodiment, a pair of slits 14e extending in the axial direction and facing each other is formed in a portion where the female screw 14d of the middle cylinder 14 is formed. By pushing the screw shaft 16 straight into the middle cylinder 14 while pushing back 14d in the outer diameter direction, assembly can be performed in a short time.

The length of each longitudinal rib 16a in the circumferential direction is preferably set to be larger than the width of each slit 14e.
Even when e is present, the male screw 16b formed on each longitudinal rib 16a always screws with the female screw 14d even at a part thereof, so that the continuity of screwing can be maintained. At the tip of the screw shaft 16, a rod-shaped receiving portion 24 for holding the rod 22 is formed. The rod-shaped object receiving portion 24 may be formed integrally with the screw shaft 16 to reduce the number of parts as in the present embodiment, or may be a separate product integrally connected to the screw shaft 16. Is also good. As shown in FIG. 4C, the rod-shaped object receiving portion 24 has four holding pieces 24 aligned with the vertical ribs 16a.
The rod 22 is held between the inner peripheral surfaces of the holding pieces 24a.

As shown in FIG. 5, an annular projection 18a is formed on the outer peripheral surface of the front cylinder 18 to fit into the annular groove 12a of the rear cylinder 12, and the inner cylinder is formed on the inner peripheral surface thereof. 14
An annular groove 18b fitted to the annular projection 14c is formed,
As a result, the front cylinder 18 is connected to the rear cylinder 12 and the middle cylinder 14 so as to be relatively rotatable and immovable in the axial direction.
Note that an annular groove may be used instead of the annular projection 18a, an O-ring may be set between the annular groove and the annular groove 12a, and silicone oil, wax, or the like may be applied. Thereby, a profound feeling can be given to the relative rotation between the front cylinder 18 and the rear cylinder 12.

At the front end of the inner peripheral surface of the front cylinder 18, four longitudinal grooves 18c extending in the axial direction are formed.
The holding piece 24a of the rod-shaped object receiving portion 24 and the vertical rib 16a of the screw shaft 16 are fitted into c, respectively. In this way, the front cylinder 18 accommodates the screw shaft 16 so that it can move in the axial direction and cannot rotate relatively. The cap 20 is detachably engaged with the distal end of the rear cylinder 12 and covers the front cylinder 18 when not in use. However, the cap 20 may be omitted depending on the type of the rod.

In the above-described rod-shaped object feeding container 10, when the rod-shaped object 22 is not used at all, the rod-shaped object receiving portion 24 is located at the rearmost portion of the front cylinder 18, and FIG. The rod 22 is slightly retracted from the tip of the front tube 18 as compared to the state shown. When the rod 22 is used, first, the cap 20 is removed, and the front cylinder 18 is rotated in one direction relative to the rear cylinder 12 or the rear cylinder 12 relative to the front cylinder 18. Middle cylinder 14
Rotates together with the rear cylinder 12, and the front cylinder 18 and the screw shaft 16 rotate together without relative rotation.
Relative rotation occurs between the middle cylinder 14 and the screw shaft 16, and the screw shaft 16 is axially moved with respect to the middle cylinder 14 by screwing the male screw 16 b of the screw shaft 16 and the female screw 14 d of the middle cylinder 14. The rod-shaped object receiving portion 24 integrated with the screw shaft 16 moves in the axial direction. During this movement, since the front cylinder 18 and the screw shaft 16 cannot rotate relative to each other, the rod 22 does not rotate in the front cylinder 18. That is, since the rod 22 moves linearly with respect to the front cylinder 18, the sliding amount between the rod 22 and the front cylinder 18 can be minimized. On the other hand, since the rod 22 is sandwiched by the clamping pieces 24a fitted into the vertical grooves 18c, the outer diameter of the rod 22 is uniform between the portion clamped by the clamping piece 24a and the portion not clamped. Even so, it is possible to bring the portion of the rod-shaped material 22 that is not clamped close enough to be in sliding contact with the portion of the inner peripheral surface of the front cylinder 18 where the vertical groove 18c is not formed. In this way, the rod-shaped object 22 is
It is possible to prevent rattling inside. Rod 22
Since the outer diameter may be uniform, there is no need to perform processing such as shaving the rod-shaped object in order to hold the rod-shaped object in the rod-shaped object receiving portion 24, and the manufacturing process can be simplified.

As described above, the rod-shaped material 22 is extended from the tip of the front cylinder 18 and can be used. When the use ends, the relative rotation of the front tube 18 and the rear tube 12 in the opposite direction to the front direction causes the rod 22 to move linearly in the retreating direction with respect to the front tube 18. When the rod-shaped material 22 is used and is consumed and consumed at the maximum, the rod-shaped material receiving base abuts on the tip of the vertical groove 18c, and the rod-shaped material 22 is prevented from being further extended.

When the rod 22 is at the maximum extended position or at the maximum retracted position and cannot move any further, the user further rotates the front cylinder 18 and the rear cylinder 12 relative to each other. In this case, the screw shaft 16 may be idle in order to prevent the female screw 14d and the male screw 16b from being damaged. For this purpose, it is preferable to provide a radial gap between the portion of the middle cylinder 14 where the female screw 14d is formed and the inner peripheral surface of the corresponding front cylinder 18. For this reason, the inner diameter of the inner peripheral surface of the front cylinder 18 is made slightly larger than the outer diameter of the screw shaft 16, or two or three of the threads of the male screw 16 b at the front and rear ends of the screw shaft 16 are adjusted. It should be lower than others. Accordingly, even when the relative rotation between the screw shaft 16 and the middle cylinder 14 occurs by force, the female screw 14d escapes in the outer diameter direction by utilizing the elasticity of the slit 14e, so that the screw shaft 16 may idle. it can. Therefore, the female screw 14
d and the male screw 16b can be prevented from being damaged.

The above-described rod-shaped object feeding container according to the present embodiment can be applied to both a disposable type and a refillable cartridge type. For example, when applied to a disposable type, the fitting between the annular groove 12a and the annular projection 18a in the rear cylinder 12 and the front cylinder 18 may be set to be strong so that a general user cannot remove it. Conversely, when applied to the cartridge type, the fitting between the annular groove 12a and the annular projection 18a in the rear cylinder 12 and the front cylinder 18 does not come off during normal use, but comes off when a general user pulls with force. It is good to set to about.

That is, when applied to the cartridge type, the front cylinder 18 is provided with the middle cylinder 14 and the screw shaft 16 together with the rear cylinder 12.
The cartridge can be configured with these components. With such a cartridge, when the cartridge is handled alone, the rod-shaped material 22 is completely removed from the front cylinder 1.
8 and is sanitary. Since the key 14a, which is a detent portion of the middle cylinder 14, projects from the rear of the front cylinder 18, when the cartridge is handled alone, the key 14a is held by the middle cylinder 14 projecting from the front cylinder 18 with respect to the front cylinder 18. When rotated, the rod-shaped material 22 may be unwound. In order to prevent such an erroneous operation, the length L of the protrusion of the middle cylinder 14 from the rear of the front cylinder 18 is preferably set to such a degree that a general user cannot perform a rotation operation with a finger. Preferably, it is set to about 2 to 3 mm.

FIG. 6 is a sectional view showing another embodiment of the present invention, taken along line DD of FIG. In the present embodiment, the cross-sectional shape is not circular, but is directed to a non-circular elliptical rod 22 ′, and the rod-feeding container of the present invention is designed for such a non-circular rod 22 ′. Also, the holding piece 24a 'of the rod-shaped object receiving portion 24' is arranged so that the non-circular rod-shaped substance 22 'can be held, and the shape of the inner peripheral surface of the front cylinder 18' is changed from a circle to an ellipse adapted to the rod-shaped substance 22 '. Can be dealt with simply by changing to

In the above embodiment, the slit 14e is provided at the tip of the middle cylinder 14 for ease of assembling the screw shaft 16 and the middle cylinder 14. In order to simplify the assembly with the middle cylinder 14, a slit similar to the slit 14e is provided at the rear end of the front cylinder 18, and the annular projection 14c of the middle cylinder 14 is inserted into the annular groove 18b while expanding this slit. You may make it fit.

As described above, claims 1 to 9 are described.
According to the described invention, the rod-like object is not allowed to rotate relative to the front cylinder together with the screw shaft, and the rod-like substance is linearly fed out to the front cylinder in the front cylinder. The amount of sliding with the front cylinder can be minimized.
Further, the present invention can be applied to a rod-shaped object having a non-circular cross section.

According to the second aspect of the present invention, since the bar is held by the holding piece fitted into the vertical groove, the rod has a portion to be held and a portion not to be held having an outer diameter. Even if it is uniform, it is possible to bring the portion of the rod-shaped object that is not clamped close enough to be able to slidably contact the portion of the inner peripheral surface of the front cylinder where the vertical groove is not formed. Thus, it is possible to prevent the rod-shaped object from rattling in the front cylinder. Since the rod-shaped object may have a uniform outer diameter, there is no need to perform processing such as shaving the rod-shaped object, and the manufacturing process can be simplified.

According to the third aspect of the present invention, since the vertical ribs of the screw shaft are fitted into the vertical grooves, the outer diameters of the screw shaft and the rod-shaped object receiving portion can be made substantially equal.

Furthermore, by pushing the screw shaft straight into the middle cylinder while pushing the female screw in the outer diameter direction while expanding the slit, assembly can be performed in a short time.

Further, even if the user tries to rotate the screw shaft further in a state in which the screw shaft is protruded or retracted to the maximum during use, the female screw can escape in the outer diameter direction by utilizing the elasticity of the slit. As a result, the screw shaft can run idle, thereby preventing damage to the female screw and the male screw. According to the fifth aspect of the invention, the same effect as that of the fourth aspect of the invention can be achieved, and even if a slit exists, the male screw formed on each vertical rib is always a female screw even if a part thereof. , The continuity of the screwing can be maintained.
