Description

The present disclosure relates to a cosmetic dispensing container that dispenses cosmetics stored therein.

Conventionally, various types of cosmetic dispensing containers for dispensing cosmetics have been known. Japanese Unexamined Patent Publication No. 2010-178828 describes a cartridge-type cosmetic storage container. The container body of this cartridge-type cosmetics storage container includes a hakama tube, a body tube provided inside the hakama tube, and an inner fitting provided at an opening of the body tube. The container body further includes a cartridge body, and the cartridge body includes a middle cylinder. The body barrel has a bottomed stop portion against which the lower end of the middle barrel of the cartridge body comes into contact. In addition to the above-mentioned inner cylinder, the cartridge body includes a filling case for filling the cosmetic, an operating claw body, an extrusion piece, and a slider. The cartridge body is replaceable with respect to the barrel and inner fittings of the container body.

Japanese Patent Application Publication No. 2010-178828

In the above-mentioned cartridge-type cosmetic storage container, when the cosmetic inside the filling case is used up, the cartridge body containing the filling case can be removed and a new cartridge body installed, thereby eliminating the need to discard the container body. It is considered to be an economical and environmentally friendly container.

However, the above-mentioned cartridge body includes a middle cylinder, a filling case, an operating claw body, an extrusion piece, and a slider. Therefore, after the cosmetic inside the filling case is used up, not only the filling case but also the cartridge body including a plurality of parts is discarded. As described above, since a plurality of parts are discarded, there is a need to further reduce the number of parts discarded after use of cosmetics.

The present disclosure aims to provide a cosmetic dispensing container that can reduce the number of discarded parts.

A cosmetic dispensing container according to the present disclosure includes a cylindrical pipe material capable of accommodating a cosmetic material, a tip tube in which the pipe material can be detachably housed and has an opening through which the cosmetic material is exposed, and a tip tube. A container body that is removably engaged, a cylindrical female screw member that is rotatable in synchronization with the container body inside the container body and has a female screw on its inner surface, and a female screw of the female screw member that is screwed together. The push rod has a male thread and pushes out the cosmetic contained in the pipe material to the outside of the pipe material, and a rotation stopper member provided inside the tip tube restricts rotation of the push rod in the circumferential direction, The pipe material can be replaced with the tip tube removed from the container body.

In this cosmetic dispensing container, a pipe material for accommodating the cosmetic is provided inside the tip tube, and the tip tube is removably engaged with the container body. A cylindrical female screw member is provided inside the container body, and the female screw member has a female screw into which the male screw of the push rod is screwed. The push rod is provided on the opposite side of the opening of the tip tube when viewed from the cosmetic stored inside the pipe material. The rotation of the push rod in the circumferential direction is restricted by the rotation stopper member, and the push rod moves forward by the screwing action of the male screw and the female screw described above. At this time, the cosmetic stored in the pipe material is pushed by the advancing push rod and exposed through the opening of the tip tube for use. The tip tube is detachable from the container body, and the pipe material can be replaced with the tip tube removed from the container body. Therefore, it is possible to replace only the pipe material with the tip tube removed from the container body, so the number of parts to be discarded can be reduced. Therefore, the number of parts that are discarded after using the cosmetic can be reduced.

The rotation stopper member may have a protrusion on the outer peripheral surface, and the pipe material may have a groove into which the protrusion is caught from the end of the pipe material on the rotation stopper side. In this case, the protrusion of the rotation stopper member is caught in the groove of the pipe material, so that the pipe material can be engaged with the rotation stop member. Therefore, in a state where the leading tube is removed from the container body, it is possible to prevent the pipe material from unintentionally coming off from the rotation stopper projection and the push rod.

The push rod advances as the container body rotates in one direction, and is provided inside the container body and includes a ratchet member that restricts rotation of the container body in the opposite direction from the one direction. The screw member may have second ratchet teeth that engage first ratchet teeth formed on the threaded member. In this case, the push rod moves forward as the container body rotates in one direction, and rotation of the container body in the opposite direction is regulated by the ratchet member. Therefore, rotation of the container body in the opposite direction and unintentional retreat of the cosmetic and the push rod can be prevented.

The rotation stopper member is cylindrical and engages with the ratchet member in a synchronously rotatable manner, and when the front tube is removed from the container body, the rotation stopper moves forward and stops engaging with the ratchet member. It may be released to allow rotation in the circumferential direction relative to the ratchet member. In this case, when the leading tube is removed from the container body, the rotation stopper moves forward and disengages from the ratchet member, and becomes rotatable relative to the ratchet member. Therefore, the push rod also rotates as the rotation stopper member rotates with respect to the ratchet member, so that the push rod can be moved backward in a state where the leading tube is removed from the container body.

A tail plug located on the side of the container body opposite to the front tube may be provided, and the tail plug may seal an opening located on the side of the container body opposite to the front tube. In this case, the tail plug seals the opening of the container body, thereby ensuring airtightness of the cosmetic dispensing container.

The pipe material can be engaged with the push rod along the axial direction of the pipe material, and the pipe material can be replaced by being removed from the push rod. A spring member may be provided that biases the push rod to move the push rod backward. In this case, when the pipe material is engaged with the push rod, the push rod is maintained in an advanced state due to the engagement. Then, when the pipe material is removed from the push rod, the engagement of the pipe material with the push rod is released, so that the push rod is automatically retreated by the biasing force of the spring member. Therefore, since the push rod can be automatically returned to the initial position when replacing the pipe material, a new pipe material can be easily installed, and the usability of the cosmetic dispensing container can be improved.

According to the present disclosure, the number of discarded parts can be reduced.

The insertion portion 4b has a smaller diameter than the cylindrical portion 4c, and the outer diameter of the cylindrical portion 4c is approximately the same as the outer diameter of the container body 3. The tail plug 4 is rotatable relative to the container body 3 in the circumferential direction, and functions as an operating tube through which the cosmetic material M is dispensed by rotating relative to the container body 3.

A housing region 4d for housing the rear portion of the female screw member 8 is provided on the inner surface of the insertion portion 4b. An annular protrusion 4f that engages in the axial direction with an annular recess 3c formed on the inner surface of the container body 3, and an annular recess 4g in which the O-ring 22 is accommodated are formed on the outer peripheral surface of the insertion portion 4b. . The O-ring 22 accommodated in the annular recess 4g is provided in close contact with the inner surface of the container body 3 to ensure airtightness inside the container body 3.

The procedure for using the cosmetic dispensing container 100 configured as above will be explained. First, the cap 10 is removed from the front tube 2, and the container body 3 and tail plug 4 are relatively rotated in one direction. When the container body 3 and tail plug 4 are rotated relative to each other in one direction, the tail plug 4 and female screw member 8 rotate synchronously, and the container body 3, ratchet member 7, tip tube 2, pipe material 1, and push rod 5 rotate synchronously. As a result, the screwing action of the screwing portion T works, and the push rod 5 moves forward with respect to the female screw member 8. As the push rod 5 moves forward, the push rod 5 pushes the cosmetic M inside the pipe material 1 forward, and the cosmetic M protruding forward from the tip tube 2 is applied to the area to be applied (for example, the user's skin). As a result, the cosmetic M is ready for use.

As the push rod 5 moves forward, the spring member 9 gradually contracts. Further, the ratchet mechanism R restricts the relative rotation of the female screw member 8 and the ratchet member 7 in the opposite direction to the one direction, so the relative rotation of the container body 3 and the tail plug 4 in the opposite direction is restricted. . Therefore, in this embodiment, the push rod 5 does not retreat until the cosmetic M is used. In addition, when the front tube 2 is attached to the container body 3, the protrusion 6c of the rotation stopper 6 engages the protrusion 7h of the ratchet member 7 in the circumferential direction, so the rotation stop member 6 is engaged with the ratchet. Rotates in synchronization with member 7.

When the cosmetic material M is used and the cosmetic material M inside the pipe material 1 is used up, the push rod 5 reaches its forward limit and the front end of the push rod 5 moves toward the pipe material 1, as shown in FIGS. 12, 13, and 14. The pipe material 1 is protruded forward from the pipe material 1, and the leading tube 2 is removed from the container body 3 to replace the pipe material 1. It is possible to replace the pipe material 1 by itself.

That is, by removing the pipe material 1 into which the push rod 5 is inserted from the push rod 5, the pipe material 1 can be replaced. First, when the leading tube 2 is removed from the container body 3 in order to replace the pipe material 1, the protrusion 6c of the rotation stopper 6 moves forward against the protrusion 7h of the ratchet member 7 due to the biasing force of the spring member 9. do. In this state, the rotation stopper member 6 is disengaged from the ratchet member 7 in the circumferential direction and can rotate relative to the ratchet member 7.

Before the tip tube 2 is removed from the container body 3 and the pipe material 1 is replaced, the push rod 5 is engaged with the pipe material 1 by frictional force. However, when the pipe material 1 is removed from the push rod 5, the push rod 5 is disengaged from the pipe material 1, and the rotation stopper 6 and the push rod 5 rotate with respect to the ratchet member 7, causing the spring member 9 to rotate. The push rod 5 rotates and retreats due to the urging force. At this time, the rear end of the push rod 5 comes into contact with the bottom surface 8g of the female screw member 8, and the push rod 5 is located in the same initial state as in FIG. 3.

As shown in FIG. 15, a new pipe material 1 containing cosmetics M is inserted into the tip tube 2 that has been removed from the container body 3. At this time, the pipe material 1 is inserted into the central storage area 2f from the rear side of the front tube 2, and the front end of the pipe material 1 comes into contact with the stepped portion 2h. Then, as shown in FIGS. 15 and 16, by attaching the front tube 2 into which the pipe material 1 has been inserted to the container body 3 shown in FIG. When the pipe material 1 is attached to the container body 3, the replacement of the pipe material 1 is completed.

Next, the effects obtained from the cosmetic dispensing container 100 according to this embodiment will be explained in detail. In the cosmetic dispensing container 100, a pipe material 1 for accommodating the cosmetic M is provided inside a tip tube 2, and the tip tube 2 is removably engaged with a container body 3. A cylindrical female screw member 8 is provided inside the container body 3, and the female screw member 8 has a female screw 8c into which the male screw 5d of the push rod 5 is screwed. The rotation of the push rod 5 in the circumferential direction is restricted by the rotation stopper 6, and the push rod 5 moves forward by the screwing action of the male screw 5d and the female screw 8c (threaded portion T).

At this time, the cosmetic M accommodated in the pipe material 1 is pushed by the advancing push rod 5 and is exposed from the opening 2b of the tip tube 2 for use. The tip tube 2 is detachable from the container body 3, and as shown in FIG. 13, the pipe material 1 can be replaced with the tip tube 2 removed from the container body 3. Therefore, it is possible to replace only the pipe material 1 with the front tube 2 removed from the container body 3, so the number of parts to be discarded can be reduced. Therefore, the number of parts that are discarded after using the cosmetic M can be reduced.

The push rod 5 moves forward as the container body 3 rotates in one direction, and is provided inside the container body 3 and includes a ratchet member 7 that restricts the rotation of the container body 3 in the opposite direction from the one direction. The ratchet member 7 has second ratchet teeth 7q that engage with first ratchet teeth 8b formed on the female screw member 8. Therefore, the push rod 5 moves forward as the container body 3 rotates in one direction, and the ratchet member 7 restricts the rotation of the container body 3 in the opposite direction. Therefore, rotation of the container main body 3 in the opposite direction and unintended retreat of the cosmetic M and the push rod 5 can be restricted.

The rotation stopper member 6 is cylindrical and engages with the ratchet member 7 so as to be able to rotate synchronously. 7 is released, and rotation relative to the ratchet member 7 in the circumferential direction becomes possible. Therefore, when the front cylinder 2 is removed from the container body 3, the rotation stopper member 6 moves forward and disengages from the ratchet member 7, and becomes rotatable relative to the ratchet member 7. Therefore, the push rod 5 also rotates due to the rotation of the rotation stopper 6 with respect to the ratchet member 7, so that the push rod 5 can be moved backward in a state where the front tube 2 is removed from the container body 3.

The cosmetic dispensing container 100 includes a tail plug 4 located on the opposite side of the container body 3 from the front tube 2, and the tail plug 4 seals an opening 3g located on the opposite side of the container body 3 from the front tube 2. Stop. Therefore, by sealing the opening 3g of the container body 3 with the tail plug 4, the airtightness of the cosmetic dispensing container 100 can be ensured.

The pipe material 1 can be engaged with the push rod 5 along the axial direction of the pipe material 1, and the pipe material 1 can be replaced by being removed from the push rod 5. is provided with a spring member 9 that biases the push rod 5 so as to cause the push rod 5 to retreat when the pipe material 1 is removed from the push rod 5. Therefore, when the pipe material 1 is engaged with the push rod 5, the state in which the push rod 5 moves forward is maintained due to the engagement. When the pipe material 1 is removed from the push rod 5, the engagement of the pipe material 1 with the push rod 5 is released, so that the push rod 5 is automatically retreated by the biasing force of the spring member 9. Therefore, since the push rod 5 can be automatically returned to the initial state when replacing the pipe material 1, a new pipe material 1 can be easily installed, and the usability of the cosmetic dispensing container 100 can be improved. Can be done.

The first embodiment of the cosmetic dispensing container according to the present disclosure has been described above. However, the present invention is not limited to the first embodiment described above, and may be further modified without changing the gist of each claim. That is, the shape, size, number, material, and arrangement of each component constituting the cosmetic dispensing container can be changed as appropriate without departing from the above gist.

FIG. 17 is a side view showing a container body 23, a pipe material 24, a piston 25, a rotation stopper 26, a push rod 27, and a cosmetic M of a cosmetic dispensing container 200 according to a modified example. FIG. 18 is an enlarged side view of the container body 23 and rotation stopper member 26 of FIG. 17. As shown in FIGS. 17 and 18, the container body 23 has a cylindrical shape, and a rotation stopper 26 protrudes from the front end of the container body 23. In addition, the structure of the container main body 23 is the same as that of the container main body 3, for example.

The pipe material 24 is arranged between a cylindrical cosmetic storage section 24b that accommodates the cosmetic M, an enlarged diameter section 24c located at the rear of the cosmetic storage section 24b, and between the cosmetic storage section 24b and the enlarged diameter section 24c. It has a tapered surface 24d located thereon. The piston 25 is located on the rear side of the cosmetic material M and on the front side of the push rod 27, and is provided to push the cosmetic material M forward.

The rotation stopper 26 has a tapered surface 26c that is exposed from the container body 23 and whose diameter decreases as the distance from the container body 23 increases, and a cylindrical outer circumferential surface 26b that is located in front of the tapered surface 26c. A protrusion 26d that protrudes radially outward is formed on the outer circumferential surface 26b. A push rod 27 projects forward from the front end of the rotation stopper 26 .

The pipe material 24 has a groove 24g from an end 24f on the rotation stopper 26 side into which a protrusion 26d is caught. The groove 24g has a first extending portion 24h extending diagonally forward from the end portion 24f, and a second extending portion 24j extending on both sides in the circumferential direction at the front end of the first extending portion 24h. The first extending portion 24h and the second extending portion 24j are, for example, substantially T-shaped. In the pipe material 24, the protrusion 26d of the rotation stopper 26 is inserted into the first extension 24h from the end 24f, and rotates relative to the rotation stopper 26, so that the protrusion 26d is caught on the second extension 24j. This engages the rotation stopper member 26 in the axial direction.

As described above, in the cosmetic dispensing container 200 according to the modified example, the rotation stopper 26 has the projection 26d on the outer peripheral surface 26b, and the pipe material 24 has the projection 26d from the end 24f of the pipe material 24 on the rotation stop member 26 side. It has a groove 24g into which it is caught. Therefore, the projection 26d of the rotation stopper 26 is caught in the groove 24g of the pipe material 24, so that the pipe material 24 can be engaged with the rotation stop member 26.

Therefore, in a state where the front tube 2 is removed from the container body 23, the pipe material 24 can be prevented from unintentionally coming off from the rotation stopper 26 and the push rod 27. Further, the cosmetic dispensing container 200 according to the modified example includes a piston 25 interposed between the push rod 27 and the cosmetic M. Therefore, since the push rod 27 does not directly push out the cosmetic M, the push rod 27 can be prevented from getting dirty and can be protected.

Note that the container body 23, pipe material 24, rotation stopper 26, and push rod 27 according to the modified example are the same as the container body 3, pipe material 1, rotation stop member 6, and push rod 5 of the first embodiment described above. It is possible to use it instead. Furthermore, it is also possible to incorporate the piston 25 into the cosmetic dispensing container 100 according to the first embodiment described above.

Although the cosmetic dispensing container 200 according to the modified example has been described above, the cosmetic dispensing container according to the present disclosure can be further modified. Below, a cosmetic dispensing container according to yet another embodiment will be described.

(Second embodiment)
FIG. 19 is a side view showing the container body 213, pipe material 214, and rotation stopper member 216 of the cosmetic dispensing container 210 according to the second embodiment. FIG. 20(a) is a side view of the pipe material 214. FIG. 20(b) is a side view of the pipe material 214 seen from a different direction from FIG. 20(a). Some of the configurations of the container body 213, pipe material 214, and rotation stopper member 216 overlap with some of the configurations of the container body 23, pipe material 24, and rotation stopper member 26 described above. Duplicate explanations will be omitted as appropriate.

The pipe material 214 has an enlarged diameter portion 214c located on the rear side. The rotation stopper 216 has a tapered surface 216c that is exposed from the container body 213 and whose diameter decreases as the distance from the container body 213 increases, and an outer circumferential surface 216b that is located in front of the tapered surface 216c. A protrusion 216d is formed on the outer circumferential surface 216b and protrudes radially outward from the outer circumferential surface 216b.

The pipe material 214 has an end face 214f facing the rotation stopper 216 side, and a locking portion 214g formed on the end face 214f, on which the rotation stopper 216 is caught. The end surface 214f of the pipe material 214 is inclined with respect to a plane perpendicular to the axial direction. The angle of inclination of the end surface 214f with respect to the plane perpendicular to the axial direction is, for example, 14° or more and 40° or less. However, the inclination angle of the end surface 214f is not limited to the above value and can be changed as appropriate. The end face 214f has an annular shape when viewed along the axial direction. For example, when looking at the end surface 214f from the rear, the end surface 214f is obliquely inclined toward the rear side as it goes counterclockwise.

The locking portion 214g is, for example, a concave portion into which the protrusion 216d of the rotation stopper 216 is inserted. The pipe material 214 has, for example, two locking portions 214g arranged along the circumferential direction of the pipe material 214. The locking portion 214g has a first extending portion 214h extending diagonally forward from the end surface 214f, and a second extending portion 214j extending on both sides in the circumferential direction at the front end of the first extending portion 214h. In the pipe material 214, the protrusion 216d of the rotation stopper 216 is inserted into the first extension part 214h from the end surface 214f, and rotates relative to the rotation stopper 216, so that the protrusion 216d is caught on the second extension part 214j. This engages the rotation stopper member 216 in the axial direction.

As described above, in the cosmetic dispensing container 210 according to the second embodiment, the projection 216d of the rotation stopper 216 is caught on the locking part 214g of the pipe material 214, so that the pipe material 214 can be engaged with the rotation stop member 216. . Furthermore, in the second embodiment, the end surface 214f of the pipe material 214 is inclined with respect to a plane perpendicular to the axial direction. The end surface 214f is inclined toward the groove-shaped locking portion 214g.

Therefore, when the projection 216d is engaged with the locking portion 214g, the projection 216d can be brought into contact with the end surface 214f and smoothly engaged with the locking portion 214g along the inclined end surface 214f. That is, no matter where on the end surface 214f the protrusion 216d comes into contact, the protrusion 216d can be smoothly guided to the second extending portion 214j of the pipe material 214, so that the rotation stopper 216 can smoothly engage with the pipe material 214. Can be done.

(Third embodiment)
FIG. 21 is a sectional view showing the internal structure of a cosmetic dispensing container 300 according to the third embodiment. The cosmetic dispensing container 300, like the cosmetic dispensing container 100, cosmetic dispensing container 200, or cosmetic dispensing container 210 described above, includes a tip tube 2, a container body 3, a push rod 5, and a rotation stopper 26 (or A stop member 216), a ratchet member 7, a female screw member 8, and a spring member 9 are provided.

The cosmetic dispensing container 300 further includes a second spring member 310. The second spring member 310 is made of, for example, SUS (Steel Use Stainless). The second spring member 310 is interposed between the female screw member 8 and the rotation stopper 26 and is provided to bias the rotation stop member 26 against the female screw member 8 . The second spring member 310 urges the rotation stopper 26 forward.

For example, the diameter of the second spring member 310 is larger than the diameter of the spring member 9. Between the rotation stopper member 26 (or rotation stopper member 216) and the female screw member 8, the second spring member 310 is arranged so as to surround the spring member 9. As described above, the cosmetic dispensing container 300 according to the third embodiment includes the second spring member 310 that biases the rotation preventing member 26, thereby attaching the rotation preventing member 26 to the pipe material 24 side (front side). Accordingly, the projection 26d (or the projection 216d) can be smoothly guided to the second extension portion 24j (or the second extension portion 214j).

(Fourth embodiment)
FIG. 22 is a sectional view showing the internal structure of a cosmetic dispensing container 400 according to the fourth embodiment. FIG. 23(a) is a side view showing the rotation stopper member 406 of the cosmetic dispensing container 400. FIG. 23(b) is a sectional view taken along line GG in FIG. 23(a). As shown in FIGS. 22, 23(a), and 23(b), the cosmetic dispensing container 400 does not include the second spring member 310, and has a rotation stopper member having a different shape from the rotation stopper member 26. 406 is different from the cosmetic dispensing container 300 according to the third embodiment.

The rotation stopper member 406 includes a spring portion 406b facing the female screw member 8. The configuration of the rotation stop member 406 other than the spring portion 406b is, for example, the same as the configuration of the rotation stop member 26 (or rotation stop member 216) described above. The spring portion 406b is located at the rear end of the rotation stopper member 406 and contacts the front end of the female screw member 8.

The spring portion 406b is, for example, a resin spring portion that can be expanded and contracted along the axial direction. For example, the spring portion 406b is formed by a body portion 406c that extends spirally, and a slit 406d that extends spirally and communicates between the inside and outside of the body portion 406c. In this way, the spring portion 406b expands and contracts along the axial direction by having the spiral main body portion 406c and the slit 406d.

As described above, in the cosmetic dispensing container 400 according to the fourth embodiment, by providing the rotation stopper member 406 having the spring portion 406b, the rotation stop member 406 is rotated by the spring portion 406b on the pipe material 24 (or pipe material 214) side (front side). ) is energized. Therefore, the protrusion 26d (or the protrusion 216d) can be smoothly guided to the second extending portion 24j (or the second extending portion 214j) of the pipe material 24. Furthermore, since the cosmetic dispensing container 400 according to the fourth embodiment does not require a component corresponding to the second spring member 310, an increase in the number of components can be suppressed.

(Fifth embodiment)
Next, a cosmetic dispensing container 500 according to a fifth embodiment will be described. FIG. 24 is a side view showing the container body 503, pipe material 504, and rotation stopper member 506 of the cosmetic dispensing container 500 according to the fifth embodiment. FIG. 25(a) is a side view showing the pipe material 504. FIG. 25(b) is a side view of the pipe material 504 viewed from a different direction from FIG. 25(a). FIG. 26(a) is a side view showing the rotation stopper 506. FIG. 26(b) is a cross-sectional view of the rotation stopper 506 taken along the line HH.

The pipe material 504 has an enlarged diameter portion 504c. Further, the pipe material 504 has an end face 504f facing the rotation stopper 506 side, and a locking portion 504g formed on the end face 504f, on which the rotation stopper 506 is caught. The end surface 504f of the pipe material 504 is inclined with respect to the plane orthogonal to the axial direction, similar to the aforementioned end surface 214f.

The locking portion 504g includes, for example, a first locking portion 504g1 and a second locking portion 504g2 having a shape different from the first locking portion 504g1. The pipe material 504 has, for example, two first locking portions 504g1 and two second locking portions 504g2. The first locking portions 504g1 and the second locking portions 504g2 are arranged alternately along the circumferential direction of the pipe material 504, for example. Each of the first locking portion 504g1 and the second locking portion 504g2 is a concave portion into which the projection 506d of the rotation stopper member 506 is inserted.

The first locking portion 504g1 has a first extending portion 504h extending forward from the end surface 504f, and an expanding portion 504j expanding at the end of the first extending portion 504h opposite to the end surface 504f. The first extending portion 504h extends, for example, in parallel to the axial direction, and the expanding portion 504j extends in an arc shape from the front end of the first extending portion 504h.

The second locking portion 504g2 has a second extending portion 504k extending forward from the end surface 504f, and a curved portion 504m located at the end of the second extending portion 504k on the opposite side to the end surface 504f. For example, the second extending portion 504k extends in parallel to the axial direction, and the curved portion 504m curves in an arc shape from the front end of the second extending portion 504k. The width of the second extending portion 504k is wider than the width of the first extending portion 504h.

As described above, the rotation stopper 506 has a tapered surface 506c and an outer circumferential surface 506b located in front of the tapered surface 506c. Four protrusions 506d are formed on the outer peripheral surface 506b. The top surface of the protrusion 506d has, for example, a peak portion 506d1 that widens from the front end toward the rear, and a curved portion 506d2 that curves into an arc shape so as to expand at the rear end of the peak portion 506d1.

Two of the four protrusions 506d enter into the first locking portion 504g1 of the pipe material 504, and the remaining two enter into the second locking portion 504g2 of the pipe material 504. At this time, since the width of the second extending part 504k is wider than the width of the first extending part 504h, the protrusion 506d smoothly enters the second locking part 504g2. On the other hand, the protrusion 506d that enters the first locking portion 504g1 moves toward the extended portion 504j while pushing the first extending portion 504h apart. Then, the protrusion 506d that has reached the expanded portion 504j is caught on the first extension portion 504h, so that the protrusion 506d can be firmly attached to the first locking portion 504g1.

As described above, in the cosmetic dispensing container 500 according to the sixth embodiment, the end surface 504f of the pipe material 504 is inclined with respect to the plane perpendicular to the axial direction, similarly to the cosmetic dispensing container 210 described above. Therefore, the protrusion 506d can be smoothly engaged with the locking portion 504g along the end surface 504f. Moreover, since the protrusion 506d is caught and locked by the first locking portion 504g1 (first extension portion 504h), it is possible to more reliably prevent the pipe material 504 from coming off from the rotation stopper member 506.

(Sixth embodiment)
Next, a cosmetic dispensing container 600 according to a sixth embodiment will be described with reference to FIG. 27. As shown in FIG. 27, the cosmetic dispensing container 600 includes a tip tube 602 that is different from the tip tube 2 described above. The front tube 602 has a stepped portion 602h that projects radially inward at its tip. The length of the stepped portion 602h in the axial direction is, for example, shorter than the length of the stepped portion 2h (see FIG. 4) described above in the axial direction. As an example, the length of the stepped portion 602h in the axial direction is approximately the same as the radial thickness of the front tube 602 at the root portion of the stepped portion 602h.

As described above, in the cosmetic dispensing container 600 according to the sixth embodiment, the axial length of the stepped portion 602h that protrudes radially inward at the tip of the tip tube 602 is equal to the thickness of the tip portion of the tip tube 602. It is about the same level. Therefore, by shortening the axial length of the stepped portion 602h of the front tube 602, the contact area between the stepped portion 602h and the cosmetic M can be made smaller, thereby preventing folding of the cosmetic M in this contact area. Can be suppressed.

(Seventh embodiment)
Next, a cosmetic dispensing container 701 according to a seventh embodiment will be described with reference to FIG. 28. As shown in FIG. 28, the cosmetic dispensing container 701 differs from the above-described embodiments in the position of the pipe material 704 with respect to the tip tube 2. The pipe material 704 is fixed in a state protruding from the opening 2b of the front tube 2.

As described above, in the cosmetic dispensing container 701 according to the seventh embodiment, the pipe material 704 filled with the cosmetic M is fixed inside the tip tube 2 in a state protruding from the opening 2b of the tip tube 2. Therefore, since the cosmetic M does not come into contact with the front tube 2 during feeding, etc., it is possible to prevent the cosmetic M from bending due to contact with the front tube 2.

Although the cosmetic dispensing containers according to various embodiments have been described above, the cosmetic dispensing containers according to the present disclosure can be further modified. For example, in the above-described embodiment, the cosmetic dispensing container 100 is provided with the ratchet member 7 that allows dispensing in only one direction. However, the cosmetic dispensing container may be capable of relative rotation in both one direction and the opposite direction. In this case, it is also possible to omit the ratchet member 7, and it is also possible to reduce the number of parts and simplify the configuration. Furthermore, in the embodiment described above, the cosmetic dispensing container 100 in which only the pipe material 1 is replaceable has been described. However, the replaceable parts are not limited to the pipe material 1, and can be changed as appropriate. For example, other parts may be replaceable together with the pipe material 1.

Furthermore, in the above-described embodiment, the cosmetic dispensing container 100 in which the cosmetic M is advanced by relative rotation of the container body 3 and the tail plug 4 has been described. However, a cosmetic dispensing container may be used in which the cosmetic is advanced by relative rotation between the front tube and the container body, and the configuration of the dispensing mechanism for dispensing the cosmetic can be changed as appropriate. Further, the cosmetic dispensing container may be provided with a knock-type extrusion mechanism or the like instead of the dispensing mechanism for dispensing the cosmetic.

Further, in the embodiment described above, when the tip tube 2 is removed from the container body 3 and the pipe material 1 is removed from the push rod 5, the rotation stopper 6 and the push rod 5 rotate, and the urging force of the spring member 9 The cosmetic dispensing container 100 in which the push rod 5 is moved back has been described. However, a cosmetic dispensing container may be used in which the push rod is moved back manually (for example, relative rotation) rather than by the biasing force of a spring member.
