Description

  The present invention relates to a bar-shaped cosmetic material feeding container used for the purpose of appropriately feeding and using, for example, a bar-shaped cosmetic material that is built in by a user.

As a conventional bar-shaped cosmetic material feeding container, for example, a screw rod having a core chuck for holding the bar-shaped cosmetic material and a portion formed as a male screw, and a rotation stopper provided on the screw rod are non-rotatable and slid in the length direction. A sleeve having an interior that is movably supported, and a cylindrical main body having a portion that is connected to the rear portion of the sleeve so as to be rotatable about an axis and that is formed as a female screw that engages with a male screw of a screw rod. The sleeve and the main body are rotated relative to each other to feed out the bar-shaped cosmetic material held on the screw rod, and the inside of the sleeve is a front section on which the core chuck slides, and the rotation stopper slides. A second section that is a rear side that moves, and the core chuck has a protruding portion protruding outward, and the core chuck is slid in the length direction by fitting with the protruding portion. The groove to support freely is the first section A groove that is formed inside and has a protrusion that protrudes toward the outside, and that supports the rotation stopper in a non-rotatable and slidable manner in the length direction by fitting with the protrusion. Is formed in the second section (see, for example, Patent Document 1).
JP-A No. 2002-264379 (Japanese Patent Application No. 2002-264379)

  By the way, according to consumer needs in recent years, a structure in which the bar-shaped cosmetic material does not come out of the core chuck or break at the position of the core chuck is required for the bar-shaped cosmetic material supply container. There is a need for a structure in which the core chuck is not deformed by the applied torque.

According to the conventional bar-shaped cosmetic supply container, the rotation stopper is provided on the rear side of the core chuck so as not to be provided on the core chuck, and the torque applied to the screw bar is not transmitted to the core chuck. Can be prevented from being deformed.
However, in the conventional bar-shaped cosmetic feed container, the protrusion of the core chuck plays a role of holding the bar-shaped cosmetic, whereas the protrusion of the rotation stopper plays a role of restraining the rotation of the screw bar and the sleeve, Since the two are different and the groove in the first section and the groove in the second section are discontinuous in the front and back, there are many cases where a step is formed at the boundary. In some cases, the core chuck may be damaged during the process of assembling the core chuck.
That is, the work of assembling the screw rod into the sleeve is to insert the screw rod into the sleeve from the rear side. Specifically, the projecting portion of the core chuck is in the first section on the back side of the second section. However, even when the core chuck hits the step of the boundary in the process of performing such work, it is thought that there are not a few cases in which the operator continues the insertion operation without noticing, In such a case, the lead chuck will be damaged.

  Here, according to the conventional bar-shaped cosmetic supply container, it is possible to easily assemble the screw rod into the sleeve through the opening formed in the sleeve, but the sleeve does not have such an opening. There are also many.

  Therefore, an object of the present invention is to prevent the situation in which the core chuck is damaged during the process of assembling the screw rod into the sleeve and to prevent the groove in the first section and the second section from being damaged. Even if a step is formed at the boundary with the groove in the section, the protruding portion of the core chuck is placed in the first section on the back side of the second section while preventing the core chuck from striking the boundary step. An object of the present invention is to provide a stick-shaped cosmetic material feeding container that can be easily fitted in a groove.

In order to solve the above problems, a stick-shaped cosmetic material feeding container according to the present invention includes a screw rod having a core chuck for holding the stick-shaped cosmetic material and a portion formed as a male screw, and the screw rod inserted from the rear side. And a sleeve having an interior for supporting the rotation stopper provided on the rear side of the core chuck so as not to rotate and to be slidable in the length direction, and to be connected to the rear portion of the sleeve so as to be rotatable about an axis. A cylindrical cosmetic delivery container comprising: a cylindrical main body having a portion formed as a female screw that engages with a male screw of a bar; and a sleeve and the main body are rotated relative to each other to feed the bar-shaped cosmetic held on the screw rod. The sleeve has a first section on the front side where the core chuck slides and a second section on the rear side where the rotation stopper slides, and the core chuck faces outward. Has a protruding part The groove is formed in the first section so as to be slidable in the length direction by fitting with the protrusion, and the rotation stopper has a protrusion protruding outward. A groove is formed in the second section to fit the protrusion so that the rotation stopper cannot rotate and is slidable in the length direction. When the screw rod is inserted, the rotation stopper When the protrusion of the core is in front of the groove of the second section, rotation around the axis of the screw rod is not restricted, and the protrusion of the core chuck protrudes when the protrusion of the rotation stop reaches the groove of the second section When the part is in front of the groove in the first section and the protrusion of the rotation stop is in the middle of the groove in the second section, the protrusion of the core chuck fits into the groove in the first section. Yes.
Here, the part formed as a male screw includes a group of protrusions intermittently disposed on the outer surface or a group of protrusions spirally and intermittently disposed on the outer surface, which functions in the same manner as a screw thread. It includes a formed screw rod portion. Further, the portion formed as the female screw is a group of protrusions intermittently disposed on the inner surface or a group of protrusions spirally and intermittently disposed on the inner surface, which functions similarly to the thread. Including a portion of the body formed.
According to such a bar-shaped cosmetic material supply container, when the screw rod is inserted, the rotation around the axis of the screw rod is not restricted when the protrusion of the rotation stopper is in front of the groove of the second section, and the rotation is prevented. When the protruding part of the core chuck is in front of the groove in the first section when the protruding part of the stopper reaches the groove in the second section, and the protruding part of the rotation stopper is in the middle of the groove in the second section Since the protrusion of the core chuck fits into the groove in the first section, in the process of assembling the screw rod into the sleeve, the timing before the protrusion of the core chuck fits into the groove in the first section The protrusion of the rotation stopper can be fitted with the groove of the second section, and the groove of the second section can be a guide rail, and the protrusion of the core chuck can be fitted with the groove of the first section. It becomes possible to be guided to.
Therefore, according to this, even when a step is formed at the boundary between the groove in the first section and the groove in the second section, the core chuck is prevented from hitting the step of the boundary. It is possible to easily fit the protrusion into the groove in the first section on the back side of the second section, thereby damaging the core chuck in the process of incorporating the screw rod into the sleeve Can be reliably avoided.

  In such a technical means, after the protruding portion of the core chuck is fitted into the groove in the first section, the core chuck hits the foremost portion in the sleeve as regulating the advance limit of the screw rod feeding operation. From the standpoint of more reliably avoiding the situation of damaging the core chuck in the process of incorporating the screw rod into the sleeve so that the situation can be effectively avoided, the screw rod moves out. It is preferable that the advance limit is controlled by a portion of the screw rod other than the core chuck.

  According to the bar-shaped cosmetic material supply container according to the present invention, it is possible to reliably avoid a situation in which the core chuck is damaged in the process of incorporating the screw bar into the sleeve.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a longitudinal sectional view showing the assembly start situation of the stick-shaped cosmetic material supply container, FIG. 4 is a cross-sectional view taken along the line AA of FIG. 3, and FIG. 6 is a cross-sectional view taken along the line B-B of FIG. 5, FIG. 7 is a vertical cross-sectional view showing the end of assembly of the stick-shaped cosmetic material supply container, and FIG. 8 is a cross-sectional view taken along the line CC of FIG. 9 is a sectional view taken along the line DD.

  In the present embodiment, the bar-shaped cosmetic material feeding container is configured to be used for the purpose of appropriately feeding and using the eyebrow 10 that is a bar-shaped cosmetic material in which the user is built (see FIGS. 1 to 3). .

  And this rod-shaped cosmetic material supply container is comprised as a thing provided with the screw rod 1, the cylindrical sleeve 2, and the cylindrical main body 3 as shown in these figures.

  Hereinafter, each of these components will be described in more detail.

(1) Screw rod 1
As shown in FIGS. 1 to 3, the screw rod 1 is configured to have a core chuck 11 for holding a bar-shaped cosmetic material and a portion 12 formed as a male screw.

  As shown in these drawings, the screw rod 1 is configured such that a rotation stopper 13 is provided on the rear side of the core chuck 11 with an interval.

  Such a screw rod 1 can be housed and assembled in a sleeve 2 and a main body 3 which will be described later. As a result, the eyebrow held by the screw rod 1 by rotating the sleeve 2 and the main body 3 relative to each other. It is possible to realize a basic configuration of a stick-shaped cosmetic material supply container that can supply 10.

  Specifically, as shown in FIGS. 1 to 3 and 5, the core chuck 11 is configured to have a protrusion 11 a that protrudes outward and extends in the length direction.

  Here, as shown in these drawings, the core chuck 11 requires that the core chuck 11 has a protrusion 11a that protrudes outward and extends in the length direction. By allowing the core chuck 11 to be slidably supported in the length direction in the sleeve 2 so as to fit into the groove 21a of the section 21, the eyebrow 10 can be fed more stably. It is for making it a possible stick-shaped cosmetic material feeding container. Therefore, if it plays such a role, in the present invention, for example, a protrusion or other protrusion that protrudes outward is used instead of the protrusion that protrudes outward and extends in the length direction. Is possible.

  Further, as shown in FIGS. 1 to 3, 7, and 9, the rotation stopper 13 is configured to have a protrusion 13 a that protrudes outward and extends in the length direction.

  Here, as shown in these drawings, it is required that the rotation stopper 13 has a protrusion 13a protruding outward and extending in the length direction. By allowing the lead chuck 11 to be guided so as to fit in the groove 22a of the section 22 of the first section 21, the protrusion 11a of the core chuck 11 is moved to the first section 21 while preventing the core chuck 11 from hitting the step 23 of the boundary. This is to provide a stick-shaped cosmetic material feeding container that can be easily fitted into the groove 21a. Therefore, if it plays such a role, for example, a protrusion or other protrusion that protrudes outward is used instead of the protrusion 13a that protrudes outward and extends in the length direction in the present invention. It is possible.

  In the present embodiment, when the screw rod 1 is inserted, rotation around the axis of the screw rod 1 is not restricted when the protrusion 13a of the rotation stopper 13 is in front of the groove 22a of the second section 22, When the protrusion 13a of the rotation stopper 13 reaches the groove 22a of the second section 22, the protrusion 11a of the core chuck 11 is in front of the groove 21a of the first section 21, and the protrusion 13a of the rotation stopper 13 is The protrusion 11 a of the core chuck 11 is configured to fit with the groove 21 a of the first section 21 when it is in the middle of the groove 22 a of the second section 22.

  That is, the screw rod 1 in the present embodiment is a position where the core chuck 11 is in the second section 22 and the rotation stopper 13 is on the rear side of the second section 22 (see FIG. 4). It can be rotated about 60 ° around the axis (see FIG. 5), and the protrusion 13a of the rotation stopper 13 and the groove 22a of the second section 22 are fitted (see FIGS. 7 and 9). The position where the core chuck 11 is in the second section 22 (see FIG. 6) and the position where the protrusion 11a of the core chuck 11 fits the groove 21a in the first section 21 (see FIGS. 8 and 9). It is configured to be movable in the length direction.

  In the process of assembling the screw rod 1 into the sleeve 2 by such a screw rod 1, the rotation stopper 13 is at a timing before the protrusion 11 a of the core chuck 11 is fitted into the groove 21 a of the first section 21. The protrusion 13a of the core chuck 11 can be engaged with the groove 22a of the second section 22 and the groove 22a of the second section 22 is used as a guide rail. 21 can be guided so as to fit into the groove 21a.

  In other words, the screw rod 1 prevents the core chuck 11 from hitting the step 23 at the boundary, and the first section 21 on the back side of the second section 22 is placed on the protrusion 11a of the core chuck 11. It is possible to realize a stick-shaped cosmetic material feeding container that can be easily fitted into the groove 21a.

  Here, as shown in FIGS. 4 and 5, the screw chuck 1 is at a position where the core chuck 11 is in the second section 22 and the rotation stopper 13 is at the rear side of the second section 22. The reason why it is required to be able to rotate about 60 ° around the axis is the timing before the protrusion 13a of the rotation stop 13 is fitted to the groove 22a of the second section 22, and so on. By restraining the core chuck 11, it is possible to reliably eliminate the situation in which the screw rod 1 cannot be rotated and the protrusion 13 a of the rotation stopper 13 cannot be engaged with the groove 22 a of the second section 22. The protrusion 11a of the core chuck 11 is easily fitted into the groove 21a of the first section 21 so that the groove 11a does not hit the step 23 between the groove 21a of the first section 21 and the groove 22a of the second section 22. Stick-shaped cosmetics can be fed In order to ensure the basic functionality of the vessel. Therefore, if it plays such a role, in the present invention, the center chuck 11 is located in the second section 22 and the rotation stopper 13 is located behind the second section 22 around the axis. For example, instead of the screw rod 1 that can be rotated by approximately 60 °, for example, the core chuck 11 is located in the second section 22 and the rotation stopper 13 is located behind the second section 22 around the axis. It is also possible to use a screw rod that can be fully rotated, or a screw rod that can be rotated at an angle required to easily fit the protrusion 11a of the core chuck 11 into the groove 21a of the first section 21. .

  As shown in FIG. 3, the screw rod 1 in the present embodiment is configured such that the advance limit of the feeding operation is restricted by a rotation stopper 13 that is a portion of the screw rod 1 other than the core chuck 11.

  Specifically, as shown in the figure, the screw rod 1 has the rotation stop 13 abutting against the step 23 at the boundary between the groove 21a of the first section 21 and the groove 22a of the second section 22, The advance limit of the feeding operation is restricted.

  The sleeve 2 assumes that the lead chuck 11 regulates the advance limit of the feeding operation of the screw rod 1 after the protrusion 11a of the lead chuck 11 is fitted into the groove 21a of the first section 21 by such a screw rod 1. As a result, it is possible to effectively avoid the situation of hitting the frontmost part of the inside, and as a result, the situation where the core chuck 11 is damaged in the process of assembling the screw rod 1 into the sleeve 2 is more reliably avoided. It is possible to do.

(2) Sleeve 2
As shown in FIGS. 1 to 3, the sleeve 2 is assembled by inserting the screw rod 1 from the rear side, and the rotation stopper 13 provided on the rear side of the core chuck 11 is non-rotatable and slidable in the length direction. It is comprised as what has the inside supported.

  Such a sleeve 2 allows the screw rod 1 to be housed and assembled together with the main body 3 to be described later. As a result, the sleeve 2 and the main body 3 are relatively rotated and held on the screw rod 1. It is possible to realize the basic configuration of the stick-shaped cosmetic material supply container that can supply the eyebrow 10.

  In the present embodiment, as shown in FIGS. 1 to 3, 4, 6, and 8, the inside of the sleeve 2 includes a first section 21 that is a front side on which the core chuck 11 slides, and a rotation stopper. 13 is configured to include a second section 22 that is a rear side on which the slider 13 slides, and the step 23 described above is formed at the boundary between the groove 21a of the first section 21 and the groove 22a of the second section 22. Is formed.

  Here, in the first section 21, as shown in these drawings, a groove 21a for supporting the core chuck 11 so as to be slidable in the length direction by being fitted with the protrusion 11a of the core chuck 11 is formed. Has been. In addition, in the second section 22, as shown in these drawings, a groove 22a that supports the rotation stopper 13 so that it cannot rotate and is slidable in the length direction by fitting with the protrusion 13a of the rotation stopper 13. Is formed.

(3) Body 3
As shown in FIGS. 1 to 3, the main body 3 is connected to the rear portion of the sleeve 2 so as to be rotatable around an axis, and is formed as a female screw that is screwed with a portion 12 formed as a male screw of the screw rod 1. It is comprised as what has the part 31 and the chip | tip 32 which were made.

  Such a main body 3 allows the screw rod 1 to be housed and assembled together with the sleeve 2, and as a result, the eyebrow 10 held on the screw rod 1 by relatively rotating the sleeve 2 and the main body 3. It is possible to realize a basic configuration of a stick-shaped cosmetic material supply container capable of supplying

  As described above, in the bar-shaped cosmetic supply container according to the present embodiment, when the screw rod 1 is inserted, when the protrusion 13a of the rotation stopper 13 is in front of the groove 22a of the second section 22, the screw rod 1 is inserted. Rotation around the axis is not restricted, and the protrusion 11a of the core chuck 11 is in front of the groove 21a of the first section 21 when the protrusion 13a of the rotation stopper 13 reaches the groove 22a of the second section 22. The protrusion 11a of the core chuck 11 is configured to fit the groove 21a of the first section 21 when the protrusion 13a of the rotation stopper 13 is in the middle of the groove 22a of the second section 22. .

  In other words, according to such a bar-shaped cosmetic material supply container, in the process of assembling the screw rod 1 into the sleeve 2, the protrusion 11 a of the core chuck 11 is not fitted into the groove 21 a of the first section 21. At the timing, the protrusion 13a of the rotation stopper 13 can be fitted into the groove 22a of the second section 22, and the groove 22a of the second section 22 becomes a guide rail, and the protrusion of the core chuck 11 The strip 11a can be guided so as to fit into the groove 21a of the first section 21.

  Therefore, according to this, even when the step 23 is formed at the boundary between the groove 21a of the first section 21 and the groove 22a of the second section 22, the core chuck 11 does not hit the step 23 of the boundary. However, the protrusion 11a of the core chuck 11 can be easily fitted into the groove 21a of the first section 21 on the back side of the second section 22, whereby the screw rod 1 can be fitted into the sleeve 2. It is possible to reliably avoid a situation in which the core chuck 11 is damaged in the process of incorporating it into the inside.
