Japanese Unexamined Patent Publication No. 2008-148905

By the way, in the double-headed cosmetics disclosed in Patent Document 1, it is an object of the invention to shorten the overall length dimension including the first coating unit and the second coating unit.
Therefore, when exchanging the first coating unit and the second coating unit, no special consideration is given to the ease of attachment / detachment of each with the joint portion at the center.

However, in this type of cosmetics, the first coating unit and the second coating unit need to be replaced as the cosmetics are consumed.
For this reason, in general, female threads are applied to the inner surfaces of both front and rear ends of the central main body shaft (the joint portion), and male threads applied to the first coating unit and the second coating unit are applied to the front and rear. By screwing into each female screw of the above, each coating unit can be individually mounted on both sides of the main body shaft.

In this case, when the central main body shaft is injection-molded, a mold configuration is generally adopted in which the substantially central portion of the inner surface of the main body shaft is the parting line (core abutting surface) of the front and rear core pins. According to this, it is necessary to preliminarily process each of the front and rear core pins to form a female thread on the main body shaft, and when the front and rear core pins are released, the formed female thread portion of the main body shaft is removed. It is necessary to perform the so-called forcible release operation of forcibly expanding and pulling out the core pins in the axial direction for each of the front and rear core pins.

The present invention facilitates the molding of the main body shaft by considering the arrangement configuration including the female screw and the parting line applied to the main body shaft, particularly for the central main body shaft used in the above-mentioned double-headed cosmetics and the like. A main object of the present invention is to provide a rod-shaped feeding container capable of ensuring the property and improving the operability of attaching and detaching the first and second coating units to and from the main body shaft.

In the rod-shaped body feeding container according to the present invention, which has been made to solve the above-mentioned problems, the first coating unit and the second coating unit are detachably attached to the front and rear of the main body shaft with the main body shaft at the center. A rod-shaped feeding container having a rod-shaped feeding function in at least one of the first coating unit and the second coating unit, the main body shaft is formed in a cylindrical shape and spirals on the inner peripheral surface of the central portion in the axial direction. A continuous female screw is applied in a shape, and a parting line at the time of forming the main body shaft is positioned on one of the inner peripheral surfaces in the axial direction avoiding the formation position of the female screw, and the first coating is performed. The unit and the second coating unit are inserted from the front and back of the main body shaft, and each male screw formed on each of the first coating unit and the second coating unit is applied to the female screw provided on the inner peripheral surface of the main body shaft. By screwing, the first coating unit and the second coating unit are attached to the main body shaft, respectively.

In this case, in one preferred embodiment, the coating unit having the function of feeding out the rod-shaped body has a central shaft having a male screw screwed to the female screw provided on the main body shaft, and the coating unit can rotate relative to the center shaft. Along with being attached, a tip shaft for feeding the rod-shaped body from the tip portion with relative rotation is provided. Then, at the final stage of screwing in which the male screw of the central shaft finishes screwing into the female screw provided on the main body shaft, the ribs formed along the axial direction of the main body shaft side and the central shaft side are configured to overcome each other. It is desirable that the torque required for the ribs to overcome each other is set to 5 times or more the torque required for feeding out the rod-shaped body by the relative rotation of the center pole and the front shaft.

According to the rod-shaped body feeding container according to the present invention, a spirally continuous female screw is applied to the inner peripheral surface of the center of the main body shaft formed in a cylindrical shape. Therefore, regardless of the front-rear direction of the main body shaft, the first and second coating units can be attached to both sides of the main body shaft by utilizing the first half portion and the second half portion of the female screw, respectively.

In addition, since the parting line at the time of main body shaft molding is located on the inner peripheral surface of either the front or rear in the axial direction avoiding the female screw forming position, by applying the female screw molding mold to only one core pin, The main body shaft can be molded. Similarly, the above-mentioned forcible removal in the mold release of the core pin can be handled by only one core pin, so that the mold of the main body shaft can be released.

Further, the torque required for the ribs to overcome each other when attaching the coating unit having the rod-shaped body feeding function to the main body shaft is set to be five times or more the torque required for feeding the rod-shaped body.
As a result, it is possible to provide a rod-shaped feeding container having preferable operability, which allows the two portions that rotate relative to each other to be immediately determined by the touch of a hand.

The rod-shaped body feeding container according to the present invention will be described based on an example of a cosmetic tool using a solid core eyeliner as a rod-shaped body housed in the container.
In each of the drawings shown below, the same parts are indicated by the same reference numerals. May be explained by quoting the reference numerals attached to the drawings for each individual part.

The first embodiment of the rod-shaped delivery container according to the present invention is shown in FIGS. 1 to 8. The overall configuration is shown in FIGS. 1 to 3, and the first coating unit U1 and the second coating unit U2 are detachably attached to the front and rear of the central main body shaft 1 formed in a cylindrical shape. There is.
In the illustrated example, the first coating unit U1 uses a unit having a solid core eyeliner feeding mechanism as a rod-like body, and the second coating unit U2 uses a unit equipped with a brush. Consists of double-headed cosmetics.

Further, caps 2 and 3 formed in a bottomed cylindrical shape are attached to the first coating unit U1 and the second coating unit U2 respectively in the axial direction so as to be detachably attached to the center as shown in FIG. The appearance including the main body shaft 1 of the above is configured to form a cylinder having substantially the same diameter in the length direction.

As shown in FIG. 3, the first coating unit U1 is provided with a center pole 4 having a male screw 4a that is detachably screwed to the main body shaft 1. The rear end of the center pole 4 is closed, and the front end of the center pole 4 is provided with a front shaft 5 rotatably mounted with respect to the center pole 4.
The solid core eyeliner 6 as a rod-shaped body (hereinafter, may be simply referred to as a solid core 6) is housed in the shaft hole formed in the front shaft 5.
The leading shaft 5, the solid core 6, and the chuck 7 described later that supports the solid core 6 have different orthogonal diameters as is clear from the comparison of FIGS. 1 (A) and 1 (B), and have an elliptical cross section. ing. Thereby, by changing the direction of the solid core 6, the thickness of the line formed by the solid core 6 applied at one time can be selected according to the preference.

A screw rod 7A is integrally formed with the chuck 7 on the chuck 7 that supports the solid core 6 provided in the first coating unit U1, and the screw rod 7A is a cylindrical screw body housed in the center pole 4. It is housed in 8. A short female screw portion 8e screwed into the screw rod 7A is formed in the front end opening of the tubular screw body 8.
A coil spring 9 is arranged between the rear end portion of the toe shaft 5 and the flange portion 8b to be described later formed on the peripheral surface of the screw body 8, and the coil spring 9 causes the coil spring 9 to be used. The screw body 8 is configured to urge toward the rear end surface (bottom surface) of the center pole 4.

Therefore, when the front shaft 5 of the first coating unit U1 is gripped by one hand and the central main body shaft 1 is relatively rotated by the other hand, the central shaft 4 and the screw body 8 rotate together with the main body shaft 1. do.
As a result, the female screw portion 8a of the screw body 8 pushes out the screw rod 7A integrated with the chuck 7 in the axial direction, and the solid core 6 gripped by the chuck 7 is fed out from the tip 5b of the front shaft 5. That is, the solid core feeding mechanism provided in the first coating unit U1 includes a screw rod 7A mainly formed integrally with the chuck 7 and a screw body 8 having a female screw portion 8a screwed into the screw rod 7A. It is realized by the relative rotation of.

On the other hand, as shown in FIG. 3, the second coating unit U2 has a leading shaft 11 provided with a male screw 11a that is detachably screwed to the main body shaft 1 described above, and 2 at the front end portion of the leading shaft 11. A brush 12 formed by twisting a metal wire rod 12a or more and formed by a synthetic resin fiber bundle sandwiched between the metal wire rods 12a is provided.
The brush 12 is composed of a radial coating portion 12b extending radially along the longitudinal direction of the wire rod 12a and a brush-shaped brush coating portion 12c extending in the longitudinal direction, and is different after being coated with the solid core 6. By selectively using the two coating portions 12b and 12c, it is possible to use them properly as a blurring tool.
Further, the brush 12 is composed of a plurality of fiber bundles having a conical tapered surface formed at the tip thereof, and it is desirable that the fiber bundle is a mixture of straight fibers and non-straight fibers. The straight fiber means a fiber having a straight fiber axis, and the non-straight fiber means a fiber having a curved fiber axis, for example, a crimped fiber.
By mixing the straight fibers and the non-straight fibers in this way, it is possible to combine the rigidity of the brush during the blurring work and the suppression of the pain in the skin.

4 (A) and 4 (B) show a single item configuration of the main body shaft 1 located at the center of the rod-shaped body feeding container.
The main body shaft 1 is formed into a cylindrical shape as described above, and a spirally continuous female screw 1a is provided on the inner peripheral surface of the central portion in the axial direction. Then, the parting line 1b at the time of injection molding of the main body shaft 1 is positioned on the inner peripheral surface of either the front or rear in the axial direction avoiding the formation position of the female screw 1a.
In addition, annular step portions 1c and 1d having a slightly widened inner diameter are formed on the front and rear opening edges of the main body shaft 1, and 180-degree facing inner surfaces of the respective step portions 1c and 1d have an annular step portion 1c and 1d. A pair of short ribs 1e and 1f are formed along the axial direction, respectively.

FIG. 4C shows a state in which the main body shaft 1 is released from the mold after being injection-molded. In the injection molding of the main body shaft 1, the resin in a molten state from the gate G1 is formed in the space (cavity) formed between the upper and lower molds M1 and M2 and the core pins M3 and M4 abutted from the front and back. Is injected. At this time, the abutting surface of the core pins M3 and M4 becomes the parting line 1b.
For mold release, as an example, one core pin M4 on the gate side is released in the direction indicated by the white arrow, and then the upper and lower molds M1 and M2 are separated vertically as shown by the white arrow, and the other. The main body shaft 1 is taken out by releasing the core pin M3 of the above in the direction indicated by the white arrow.

As described above, the parting line 1b formed by the abutting surfaces of the core pins M3 and M4 is set at a position avoiding the forming portion of the female screw 1a in the central portion. By applying a molding die, the main body shaft 1 can be molded. Similarly, forcibly removing the female screw 1a portion in the mold release of the core pin M3 can be handled by only one core pin M3, so that the main body shaft can be released.

FIG. 5 shows a single item configuration of the center pole 4 constituting the first coating unit U1.
The rear end side of the center pole 4 is formed in a bottomed cylindrical shape, and the male screw 4a described above is formed on the outer peripheral surface of the rear end portion. The male screw 4a is screwed into the front half of the female screw 1a provided on the central inner peripheral surface of the main body shaft 1, so that the central shaft 4 is attached to the front end of the main body shaft 1. An annular flange portion 4b is formed on the outer peripheral surface of the center pole 4, and immediately after the flange portion 4b, a large diameter portion 4c having a diameter slightly larger than that behind the flange portion 4b is formed, and the large diameter portion 4c is formed. A small protrusion-shaped rib 4d is formed at one place along the circumferential direction of the above in a state of being in contact with the flange portion 4b.
The annular flange portion 4b described above abuts on the front end portion of the main body shaft 1 when the central shaft 4 is attached to the main body shaft 1, thereby positioning the central shaft 4 with respect to the main body shaft 1. This will be described later, along with the action of the small protruding ribs 4d.

An annular groove 4e is formed near the front end of the center pole 4, and the rear portion of the groove 4e is slightly elongated in the axial direction at an interval of 90 degrees along the circumference of the center pole 4. The ribs 4f of the book are formed so as to project.
The annular groove portion 4e and the four ribs 4f are used when the cap 2 described above is attached to the first coating unit U1, and this will be described later together with the configuration of the cap 2 described later. do.

Further, as shown in FIG. 5C, an annular groove portion 4g recessed toward the outside of the diameter is formed on the inner peripheral surface of the front end portion of the center pole 4, and the annular groove portion 4g is shown in FIG. As shown in 2 (B), by fitting the annular protrusion 5a formed on the front shaft 5, the front shaft 5 is supported so as to be relatively rotatable with respect to the center pole 4, and the front shaft with respect to the center pole 4 is supported. It functions as a retainer for 5.
Further, on the inner bottom portion of the center pole 4, a plurality of ribs 4h are formed at equal intervals along the inner circumference over a length range that occupies almost one-third of the total length of the center pole 4. The plurality of ribs 4h act so that the screw body 8 can rotate in the same direction together with the center pole 4 when the cylindrical screw body 8 described later is housed in the center pole 4.

FIG. 6 shows a tubular screw body 8 housed in the center pole 4, and a plurality of ribs 8a along the axial direction are arranged in the circumferential direction on the outer periphery of the latter half of the screw body 8. They are evenly spaced. By inserting each of the plurality of ribs 8a between the plurality of ribs 4h formed on the inner bottom portion of the center pole 4, the ribs 8a serve as a detent between the two ribs.
A collar portion 8b is formed slightly forward from the central portion in the longitudinal direction of the screw body 8, and the collar portion 8b functions as a spring receiving portion of the coil spring 9 shown in FIG.

Further, two slits 8c having the same length are provided at positions of the cylindrical portions forming the front end portion of the screw body 8 so as to face 180 degrees, and the cylindrical portion is divided into two. A circular opening 8d is formed at the end portion.
On the inner surface of the front end portion of the screw body 8 in which the cylindrical portion is divided into two, short female screw portions 8e also shown in FIG. 2B are formed so as to face each other, and the pair of female screw portions 8e facing each other are formed. , Is screwed into the screw rod 7A integrally formed with the chuck 7.

FIG. 7 shows a single item configuration of the chuck 7 integrally provided with the screw rod 7A.
An elliptical shaft portion 7a is formed on the front end portion side of the chuck 7, and four core gripping bodies 7b are formed so as to surround the shaft portion 7a so as to project forward from the shaft portion 7a. There is. The four core gripping bodies 7b support the tail end portion of the solid core 6 having an elliptical cross section orthogonal to the axis along its peripheral side surface, and the four core gripping bodies 7b. The length dimension (protruding dimension to the front) from the shaft portion 7a of the above is molded to be the same.
Inside each of the core gripping bodies 7b, ribs 7c that rise in a triangular shape with respect to each core gripping body 7b are formed linearly from the shaft portion 7a toward the front.
The length dimension of the rib 7c rising in a triangular shape is preferably 50 to 70% of the length dimension from the shaft portion 7a to the tip end portion of the core gripping body 7b.

Further, at the rear end portion of the shaft portion 7a, the screw rod 7A described above is integrally formed with the chuck 7, and the screw rod 7A is formed in a straight line and is a continuous male screw 7d along the longitudinal direction. Is formed.
The screw rod 7A is housed in the screw body 8 and the male screw 7d of the screw rod 7A is screwed into the female screw portion 8e formed in the screw body 8. Therefore, the chuck 7 moves forward due to the relative rotation of the screw body 8 with respect to the screw rod 7A, and the solid core 6 in the front shaft 5 is fed out from the front opening 5b of the front shaft 5 accordingly.

FIG. 8 shows a single item configuration of the cap 2 attached to the first coating unit U1 side. The cap 2 is preferably formed into a bottomed cylinder using a transparent resin material, and a plurality of ribs 2a are formed on the inner peripheral surface in the vicinity of the opening of the cap 2 along the axial direction. It is formed at approximately equal intervals along the line. Further, on the inner side of the formation position of the rib 2a, small protrusions 2b protruding inward are formed at intervals of 90 degrees along the inner peripheral surface.

When the cap 2 is attached to the first coating unit U1, the ribs 4f formed on the center pole 4 are inserted between the plurality of ribs 2a, so that the cap 2 rotates with respect to the center pole 4. Is blocked. Then, the small protrusion 2b protruding into the cap 2 enters the groove portion 4e, so that the cap 2 is fitted and attached to the center pole 4 with a click feeling.
The fitting force of the small protrusion 2b to the groove 4e is relatively weak, and therefore, the fitting can be easily released by pulling out the cap 2 in the axial direction. As a result, the cap 2 can be removed from the first coating unit U1.

The cap 2 is provided with the first coating unit U1 by providing a plurality of ribs 2a on the inner surface of the opening of the cap 2 to prevent the shaft from rotating with the center pole 4 on the first coating unit U1 side. The first coating unit U1 can be removed from the central main body shaft 1 together with the cap 2 by rotating the cap 2 while the cap 2 is attached to the cap 2.

Therefore, when the solid core 6 of the first coating unit U1 is consumed and it is to be replaced, the problem of getting the hands dirty by touching the first coating unit U1 with bare hands can be minimized. ..
This is because even when a new first coating unit U1 is mounted on the center pole 4, it is desirable that the first coating unit U1 is screwed into the central main body shaft 1 with the cap 2 mounted, thereby erroneously leading. By rotating the shaft 5, it is possible to avoid the problem of unnecessarily feeding out the solid core 6.

The cap 3 attached to the second coating unit U2 side is not shown as a single item configuration, but the basic configuration is the same as the example shown in FIG. 8, and corresponds to the length dimension of the second coating unit U2. Therefore, in the illustrated example, the length of the cap 3 is also formed to be slightly shorter.
Then, the cap 3 can be attached to the second coating unit U2 side by using the groove portion 11c and the rib 11d formed on the front shaft 11 on the second coating unit U2 side shown in FIG. 2 (A). This configuration is the same as the configuration of the cap 2 on the first coating unit U1 side and the groove portion 4e and the rib 4f formed on the center pole 4 to which the cap 2 is mounted.

In the first embodiment of the rod-shaped feeding container configured as described above, in order to mount the first coating unit U1 on the main body shaft 1, the rear end portion of the center pole 4 is inserted into the main body shaft 1. The male screw 4a formed on the center pole 4 is screwed into the female screw 1a formed in the central portion of the main body shaft 1 by the relative rotation.
By this screwing, the flange portion 4b formed on the center pole 4 approaches the front end portion of the main body shaft 1, and at the end of the screwing, the small protrusion-shaped rib 4d provided on the center pole 4 is inside the opening of the main body shaft 1. Overcome the rib 1e applied to.
At the time of overcoming this, the flange portion 4b of the center pole 4 comes into contact with the front end portion of the main body shaft 1, and the first coating unit U1 is attached to the main body shaft 1.

As described above, the small protrusion-shaped rib 4d on the side of the center pole 4 is locked over the rib 1e on the side of the main body shaft 1 to be mounted, so that the first coating unit is attached to the main body shaft 1. It can be determined by the feel of the hand that the U1 is securely attached.
Further, the rotational torque required to extend the solid core 6 from the front shaft 5 by the relative rotation of the center pole 4 and the front shaft 5 in the first coating unit U1 is about 0.1 to 0.5 [N · cm]. On the other hand, the tightening torque required for the above-mentioned overcoming locking can be set to about 2.3 to 3.8 [N · cm].
By setting the torque difference to 5 times or more in this way, a rod-shaped body feeding container having preferable operability capable of immediately distinguishing two parts that rotate relative to each other by the touch of a hand is provided. It becomes possible.

When the second coating unit U2 is attached to the main body shaft 1 described above, over-the-counter locking is adopted as in the example of the first coating unit U1, thereby causing the main body shaft 1 to be locked. On the other hand, it can be similarly determined by the feel of the hand that the second coating unit U2 is securely attached.

Further, in the above-described embodiment, the feeding mechanism for feeding the solid core 6 from the toe shaft 5 includes a screw rod 7A of the chuck 7 and a female screw portion 8e of the screw body 8 screwed into the male screw 7d of the screw rod 7A. Be done. The female threaded portion 8e of the threaded body 8 is provided on the inner surface of the front end portion of the threaded body 8 divided into two by two slits 8c having the same length.
Therefore, when an excessive pressure is applied in the axial direction of the solid core 6 drawn out from the front shaft 5, the female screw portions 8e of the screw body 8 retract to both outer sides, so that the screw rod 7A retracts. The solid core 6 is configured to cause a cup-down in which the solid core 6 is returned into the leading shaft 5.

In this case, when the above-mentioned cupdown occurs frequently, it is not easy to use as a product, and its value needs to be managed appropriately.
In this embodiment, the depth of each slit 8c provided on the front end portion of the screw body 8 is set to 5.8 mm. As a result, the overload load of the male screw 7d on the screw rod 7A side with respect to the female screw portion 8e on the screw body 8 side is set to 1.1 to 1.5 [N], and the above-mentioned cupdown does not occur frequently. We have obtained favorable results.

Further, in the above-described embodiment, the chuck 7 that supports the solid core 6 at the rear end portion is provided with four core gripping bodies 7b that support the tail end portion of the solid core 6.
Then, inside each of the core gripping bodies 7b, ribs 7c that rise in a triangular shape with respect to each core gripping body 7b are provided, and the length dimension of the ribs 7c that rises in a triangular shape is as described above. , It is set to 50 to 70% of the length dimension from the shaft portion 7a to the tip portion of the core gripping body 7b.
Therefore, when the solid core 6 is gripped only by the core gripping body 7b, the core gripping body 7b is expanded by the solid core 6 to reduce the contact area and it is difficult to increase the gripping force, but the core gripping body 7b Since the rib 7c is provided on the inner surface of the body, the rib 7c pierces the solid core 6 to increase the contact area and increase the gripping force, and it is possible to prevent the core from coming off when dropped.

The configuration of the second coating unit U2 shown in FIG. 9 includes a coating portion made of a flocked body, which constitutes a double-headed cosmetic tool together with the first coating unit U1 provided with a feeding mechanism of a solid core eyeliner.

FIG. 10 shows an assembled configuration of the second coating unit U2 having a coating portion made of a flocked body, and the front shaft 14 is attached so as to cover the front half portion of the central shaft 13 formed into a cylindrical shape. .. Then, the flange portion 15a of the flocked body 15 is inserted into the gap formed between the front end portion of the central shaft 13 and the front shaft 14, so that the flocked body 15 formed into a columnar shape protrudes from the front shaft 14. It is attached as.
The flocked body 15 can be obtained by flocking fine hairs on the surface of a base material formed into a columnar shape by, for example, an electrostatic flocking treatment (flocking treatment or the like). The flocked body 15 obtained by this electrostatic flocking treatment can be expected to be subjected to a natural blurring treatment over a wide range due to the action of the capillary force of the flocked portion on the surface.
