[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding container used for stick-shaped cosmetics such as lipsticks.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. 60-41846 and Japanese Utility Model Publication No. 60-41847 make it possible to push out a stick-shaped cosmetic material more than when it is normally used when the remaining amount of the stick-shaped cosmetic material is low. A dispensing container is disclosed.

In the case of the feeding container disclosed in Japanese Utility Model Publication No. 60-41846, an outer cylinder having a spiral groove on its inner peripheral surface,
An inner cylinder that is rotatably inserted in the outer cylinder, a holder that supports the rod-shaped cosmetic material and is vertically movable in the inner cylinder, and an inner cylinder that is vertically movable and is inserted in the holder. And a protruding member that can enter.

A first guide hole and a second guide hole are vertically formed in the inner cylinder, and an engaging projection provided on the holder is inserted into the first guide hole to engage with a spiral groove of the outer cylinder. An engaging protrusion provided on the protruding member is inserted into the second guide hole and engaged with the spiral groove of the outer cylinder. Further, horizontal portions are formed at the upper end of the first guide hole and the upper end of the spiral groove of the outer cylinder, respectively.

In this delivery container, when the inner cylinder is rotated with respect to the outer cylinder, the holder and the protruding member move up and down in synchronization until the engaging projection of the holder reaches the upper end of the first guide hole.
The stick-shaped cosmetic material sinks into the outer cylinder.

When the engaging protrusion of the holder enters the horizontal portion of the first guide hole and the horizontal portion of the spiral groove, the holder is prevented from moving upward and only rotates at the same height position. On the other hand, since the ejection member continues to move upward, the ejection member enters the holder and pushes up the stick-shaped cosmetic material.

It should be noted that the one disclosed in Japanese Utility Model Publication No. 60-41847 is a combination of the first guide hole and the second guide hole described above, and the basic structure is the Japanese Utility Model Publication No. 60-4.
It is the same as that of the 1846 publication.

[0008]

The above-mentioned conventional feeding container has the following problems. That is, since both the engaging protrusion of the holder and the engaging protrusion of the protruding member are engaged with the spiral groove of the outer cylinder, the relative positional relationship between the two members is the pitch of the spiral groove, the lead angle, and the first guide. Since it depends on the positions of the holes and the second guide holes in the circumferential direction, there are great restrictions in design.

The structure becomes complicated, for example, the horizontal portion must be provided in the spiral groove of the outer cylinder. Further, structurally, since the length of the horizontal portion provided in the first guide hole and the spiral groove determines the push-up dimension of the stick-shaped cosmetic material, the horizontal portion inevitably requires a certain length. .

However, when the stick-shaped cosmetic material is pushed up by the protruding member and the stick-shaped cosmetic material is pulled back into the inner cylinder by rotating the inner cylinder in the reverse direction, the engaging protrusion of the holder causes the horizontal portion of the first guide hole to move. While the inner cylinder is rotated in the reverse direction, the stick-shaped cosmetics will not be drawn into the inner cylinder until the
There is a problem that the longer the length of the horizontal portion, the worse the draw-in operability, and the shorter the horizontal portion to improve the draw-in operability, the smaller the push-up amount of the stick-shaped cosmetic material becomes.

The present invention has been made in view of the above problems of the prior art, and has a simple structure, a large degree of freedom in design, and excellent operability. An object of the present invention is to provide a stick-shaped cosmetic material feeding container that can be used.

[0012]

The present invention adopts the following means in order to solve the above problems. [Summary of the Invention] The stick-shaped cosmetic material feeding container of the present invention comprises:
(A) Outer cylinder, (b) Inner cylinder, (c) Holder, (d)
The holder and the protruding member are moved up and down in the inner cylinder by relatively rotating the outer cylinder and the inner cylinder. Each component will be described below.

<Outer Cylinder> The outer cylinder has a spiral groove on its inner peripheral surface.

<Inner Cylinder> The inner cylinder is inserted into the outer cylinder and is attached to the outer cylinder so as to be slightly movable in the axial direction and rotatable in the circumferential direction. A guide hole extending in the axial direction is provided in the peripheral wall portion of the outer cylinder.

In this guide hole, in the middle of the guide wall for guiding the second engaging projection of the protrusion member when the protrusion member is moved upward, the same direction as the inclination direction of the spiral groove when the outer cylinder is seen through from the outside. Is provided with an inclined surface. The inclined surface may be linear or curved.

<Holder> The holder is inserted into the inner cylinder so as to be able to move up and down, has a cylindrical shape with an opening at the top and bottom, and the inside of the upper part serves as a support recess for supporting the base of the bar-shaped cosmetic material. A first engagement protrusion slidably engaged with the guide hole of the inner cylinder is provided on the peripheral wall portion of the holder. Further, the peripheral wall portion of the holder is provided with an auxiliary guide hole extending axially upward from the lower end edge of the peripheral wall portion.

<Push-out member> The push-out member is inserted inside the holder so as to be movable in the axial direction, and its upper portion is brought into contact with the bottom portion of the stick-shaped cosmetic material. A second engaging protrusion is provided on the outer side portion of the protruding member, and the second engaging protrusion is inserted through the auxiliary guide hole of the holder and further slidably inserted through the guide hole of the inner cylinder. Further, it is slidably engaged with the spiral groove of the outer cylinder.

In the stick-shaped cosmetics feeding container of the present invention, the holder and the pushing member are kept until the first engaging projection of the holder hits the upper hooking portion of the guide hole of the inner cylinder to restrict the upward movement of the holder. Moves up synchronously.

Further, when the first engaging projection hits the upper retaining portion of the guide hole of the inner cylinder, the second engaging projection of the ejecting member is positioned below the inclined surface of the guide hole of the inner cylinder. After the holder is restrained from moving upward, the second engagement protrusion causes the second engagement protrusion to tilt the guide hole of the inner cylinder by slightly moving the inner cylinder from the lower portion of the outer cylinder. By climbing up the surface and then rotating the outer cylinder and the inner cylinder relative to each other, the second engaging protrusion moves upward in the guide hole of the inner cylinder and the auxiliary guide hole of the holder, and the protruding member is inserted into the support concave portion of the holder. The stick-shaped cosmetic in the support recess is pushed up by entering (the above corresponds to claim 1).

The ascending slope of the inclined surface of the guide hole is preferably set to be substantially equal to or larger than the ascending slope of the spiral groove of the outer cylinder (corresponding to claim 2).
When the gradient is set in such a relationship, the second engaging protrusion can be formed and the inclined surface can be surely climbed.

It is preferable that an elastic member is provided between the outer cylinder and the inner cylinder so as to urge the inner cylinder in a direction to draw the inner cylinder into the outer cylinder (corresponding to claim 3). In this way, the outer cylinder and the inner cylinder do not rattle.

A protrusion is provided on the side wall of the auxiliary guide hole of the holder, and the second engaging protrusion of the ejecting member is used as an auxiliary guide until the first engaging protrusion of the holder hits the upper hooking portion of the guide hole of the inner cylinder. It is locked under the protrusion of the hole,
After the holder is restricted from moving upward, when the outer cylinder and the inner cylinder are moved relative to each other in the direction of pulling out the inner cylinder from the outer cylinder to move the second engaging projection upward on the inclined surface of the guide hole of the inner cylinder, The second engagement protrusion may be configured to ride over the protrusion of the auxiliary guide hole (corresponding to claim 4).

With this arrangement, it is possible to reliably prevent the second engagement protrusion from returning to a position lower than the protrusion after the second engagement protrusion has passed over the protrusion of the auxiliary guide hole.

[Applicability of the present invention] The present invention can be used in the field of cosmetics such as lipsticks.

[0025]

[Action]

<Operation of the Present Invention> When the outer cylinder and the inner cylinder are rotated relative to each other, the second engaging projection of the ejecting member engages with the spiral groove of the outer cylinder and the guide hole of the inner cylinder, so that the ejecting member moves inward. Move up and down in the cylinder. Since the holder is connected to the protruding member via the stick-shaped cosmetic material, the holder also moves up and down in the inner cylinder in synchronization with the protruding member.

When the first engaging projection of the holder hits the upper hooking portion of the guide hole of the inner cylinder, the holder is restricted from moving upward and stops. At this time, the second engaging protrusion of the protruding member is located below the inclined surface provided in the middle of the guide hole of the inner cylinder.

After that, when the inner cylinder is pulled in the direction of pulling out from the lower part of the outer cylinder, a large upward force acts on the second engaging projection of the ejecting member via the spiral groove of the outer cylinder, and as a result,
The second engaging protrusion moves upward along the inclined groove of the guide hole,
Climb the sloped groove.

After that, when the outer cylinder and the inner cylinder are rotated relative to each other, the second engaging projection moves upward in the guide hole of the inner cylinder and the auxiliary guide hole of the holder, and as a result, the protrusion member moves in the support concave portion of the holder. And push up the stick-shaped cosmetic in the support recess.

In this stick-shaped cosmetic feeding container, the stick-shaped cosmetic can be continuously pushed up steplessly when the remaining amount of the stick-shaped cosmetic is low.

Since only the second engaging projection of the protruding member is engaged with the spiral groove of the outer cylinder and the first engaging projection of the holder is not engaged with the spiral groove, the degree of freedom in design is large. .

Since it is not necessary to provide a horizontal portion at the upper end of the guide hole of the inner cylinder, or even if it is provided, it can be made extremely short, so that there is no unnecessary movement in the retraction operation after the stick-shaped cosmetic material is ejected.

The right side wall 31b in the figure constitutes a guide wall for guiding the second engaging projection 52 to move downward.

Inside the inner cylinder 20, a plastic holder 40 is inserted so that it can be moved up and down. FIG. 7 shows a holder 40
FIG. 4 is a front view of the holder 40, and the holder 40 has a hollow cylindrical shape whose upper and lower sides are opened.

On the outer surface of the upper portion of the peripheral wall portion 41 of the holder 40,
First slidably engaged with the guide hole 31 of the inner cylinder 20
The engaging projections 42 are provided one by one at 180 degrees apart in the circumferential direction.

In addition, the peripheral wall portion 41 of the holder 40 has each first
One auxiliary guide hole 43 is provided at the same position as the engaging projection 42 in the circumferential direction and extends upward along the axial direction from the lower edge of the holder 40 to the lower side of the first engaging projection 42.

On the right side wall of each auxiliary guide hole 43 in the drawing, a protrusion 44 is formed at a portion located a predetermined distance above the lower edge of the holder 40. In this holder 40, the inside of the peripheral wall portion 41 above the auxiliary guide hole 43 is the stick-shaped cosmetic material A.
Is a support recess 47 for supporting the base of the.

A protrusion member 50 made of plastic is inserted inside the lower portion of the holder 40. FIG. 8 is a front view of the protrusion member 50. The protruding member 50 is in the shape of a hollow cylinder having upper and lower openings, and has a large-diameter cylindrical portion 51a having an outer diameter substantially the same as the inner diameter of the holder 40, and a large-diameter cylindrical portion 51a.
And a small-diameter tubular portion 51b having an outer diameter smaller than that of the large-diameter tubular portion 51a and an annular flange portion 51c protruding outward from the upper end of the small-diameter tubular portion 51b. The protruding member 50 can enter the support recess 47 of the holder 40.

On the outer peripheral surface of the lower portion of the large-diameter cylindrical portion 51a of the protruding member 50, columnar second engaging projections 52 are provided so as to be spaced apart by 180 degrees in the circumferential direction. The second engagement protrusion 52 is inserted through the auxiliary guide hole 43 of the holder 40, and further the inner cylinder 20
Of the spiral groove 1 of the outer cylinder 10 through the guide hole 31 of
3 is engaged.

FIG. 1 shows a state where the unused rod-shaped cosmetic material A is completely stored in the inner cylinder 20, and this state will be referred to as an initial state hereinafter.

In the initial state, the second engaging projection 52 of the protruding member 50 is located below the projection 44 in the auxiliary guide hole 43 of the holder 40, and has a small vertical hole in the guide hole 31 of the inner cylinder 20. It is located at the lowest limit of 32.

Further, in the initial state, the first engaging projection 42 of the holder 40 is located in the upper portion of the small-width vertical hole 32 of the inner cylinder 20. Further, in the initial state, the small-diameter cylindrical portion 51b and the flange portion 51c of the protruding member 50 are inserted into the support recess 41 of the holder 40, and the rod-shaped cosmetic material A is also filled inside the small-diameter cylindrical portion 51b. The flange portion 51c has a function of firmly connecting the protruding member 50 and the stick-shaped cosmetic material A so that they cannot move relative to each other.

Next, the operation of this feeding container will be described. <Normal operation: When the amount of stick cosmetics is sufficient>
From the initial state shown in FIG. 1, when the outer cylinder 10 is set to the non-rotating side and the inner cylinder 20 is rotated with the operation knob portion 21, the second engaging projection 52 of the protruding member 50 is aligned with the spiral groove 13 of the outer cylinder 10. Since it engages with the narrow vertical hole 32 of the cylinder 20, the second engaging projection 52 slides up on the left side wall 31a of the narrow vertical hole 32 in FIG. 6, and as a result, the ejection member 50. Is the inner cylinder 20
Move up inside. At this time, there is no relative rotation among the inner cylinder 20, the holder 40, and the protruding member 50.

By the way, the holder 40 and the protruding member 50
Are integrally connected via a stick-shaped cosmetic material A, and
Since the second engaging protrusion 52 of the protruding member 50 is locked to the protrusion 44 of the auxiliary guide hole 43 of the holder 40 from below, there is no relative movement between the holder 40 and the protruding member 50 in the axial direction.

Therefore, the protruding member 50 is the inner cylinder 20.
When the inside is moved up, the holder 40 and the protruding member 50 are integrally moved in synchronization and move up inside the inner cylinder 20, and as a result, the stick-shaped cosmetic A protrudes from the tips of the inner cylinder 20 and the outer cylinder 10. Exposed.

As shown in FIG. 2, the holder 40 stops when the first engaging projection 42 of the holder 40 hits the upper end of the guide hole 31 of the inner cylinder 20, and thereafter the first engaging projection 42. The holder 40 only horizontally rotates until it hits the edge of the lateral hole 37. After the first engaging projection 42 hits the left edge of the lateral hole 37, even if the inner cylinder 20 is further rotated in the same direction. The holder 40 is prevented from moving upward and rotating with respect to the inner cylinder 20. At this point, the tip of the holder 40 projects upward from the tip of the outer cylinder 10 and is exposed.

Then, almost simultaneously with the first engaging projection 42 of the holder 40 reaching the lateral hole 37, the second engaging projection 52 of the protruding member 50 reaches the connecting portion 34 of the guide hole 31.
Almost at the same time as the holder 40 horizontally rotates with respect to the inner cylinder 20, the protruding member 50 also horizontally rotates with respect to the inner cylinder 20, and the first engaging projection 42 abuts on the left end edge of the lateral hole 37. Almost at the same time as the second engaging projection 52,
It abuts the left end edge of and contacts the inclined surface 35.

FIG. 11 shows the positional relationship between the guide hole 31 and the second engaging projection 52 at this time.
The spiral groove 13 that engages with the engagement protrusion 52 is shown as seen through from the outside of the outer cylinder 10, and is shown by a two-dot chain line in the figure.

In this state, the outer cylinder 10 is set to the non-rotating side and the inner cylinder 2
Even when 0 is rotated in the direction of the arrow X in the figure, the second engaging projection 52 is held in a state of being caught by the inclined surface 35, and the protruding member 50 cannot rotate with respect to the outer cylinder 10 and the inner cylinder 20. And unable to move up.

More specifically, the second engaging projection 52 sandwiched between the wall surface of the spiral groove 13 and the inclined surface 35 of the guide hole 31.
Component force in the direction in which the inner cylinder 20 is lowered along the inclined surface 35 (direction of arrow Z _{1 in the} figure) acts on the inclined surface 35, and as a result, the second engagement protrusion 52 can pass over the inclined surface 35. You cannot do it.

As described above, the holder 40 and the protruding member 50 stop moving upward substantially at the same time. After that, when the stick-shaped cosmetic material A is drawn in, the outer cylinder 10 and the inner cylinder 20 are relatively rotated in the opposite direction to the above. Then, the holder 40 and the protruding member 50 rotate slightly horizontally, and the first
The engaging protrusion 42 and the second engaging protrusion 52 of the protruding member 50.
Is the right side wall 31b of the guide hole 31 of the inner cylinder 20 in FIG.
And then slides along the right side wall 31b and moves downward. As a result, the holder 40 and the protruding member 50 integrally move downward in the inner cylinder 20 in synchronization.

When the stick-shaped cosmetic material A is sufficiently projected and exposed from the holder 40, the holder 40 and the protruding member 50 are used in such a manner that they are integrally moved up and down synchronously. This is "normal operation".

<Push-up operation: When the remaining amount of the stick-shaped cosmetic material becomes small> The remaining amount of the stick-shaped cosmetic material A becomes small,
When the amount of protrusion from the holder 40 becomes short and it becomes difficult to use, the operation is performed as follows.

First, by the same operation as described above, the first engaging projection 42 of the holder 40 is inserted into the guide hole 31 as shown in FIG.
The second engaging protrusion 52 of the protrusion member 50 is abutted against the left end edge of the lateral hole 37 of the guide hole 31 and the inclined surface 35 of the guide hole 31.

Next, while the outer cylinder 10 and the inner cylinder 20 are prevented from rotating relative to each other, the operation knob 21 of the inner cylinder 20 is pulled downward with respect to the outer cylinder 10 against the elasticity of the bush ring 70 (that is, , And pull in the direction of the arrow Y in FIG. 11).

Then, the second engaging projection 52 of the protruding member 50 is moved upward along the inclined surface 35 by the pulling force of the inner cylinder 20 (arrow Z _{2 in} FIG. 11).
Direction), and as a result, the second engaging projection 52 moves in the direction of the arrow Z _{2 while} being sandwiched between the inclined surface 35 and the wall surface of the spiral groove 13. At this time, the holder 40 and the protruding member 50 rotate in the arrow X direction in the figure with respect to the outer cylinder 10 and the inner cylinder 20.

In this way, the second member of the protruding member 50 is
The engaging projection 52 climbs up the inclined surface 35 and moves into the wide vertical hole 33. At the same time, the second engaging projection 52 moves upward in the auxiliary guide hole 43 of the holder 40, gets over the projection 44, and becomes the state of FIG.

After that, the protrusion 44 functions as a backward stopper of the second engaging protrusion 52 and cannot move to a position lower than the protrusion 44.

After the second engaging projection 52 of the projecting member 50 is inserted into the wide vertical hole 33 of the guide hole 31, the force for pulling the inner cylinder 20 downward is removed. The cylinder 20 is pulled back into the outer cylinder 10 again (see FIG. 4).

Then, when the inner cylinder 20 is rotated again in the same direction as described above with the outer cylinder 10 as the non-rotating side, the second engaging projection 52 of the protruding member 50 causes the guide hole 31 of the inner cylinder 20 to rotate.
Moves upward along the wide vertical hole 33 and the auxiliary guide hole 43 of the holder 40, that is, the protrusion member 50 moves upward in the holder 40.

As a result, the stick-shaped cosmetic A is ejected from the protruding member 5.
The stick-shaped cosmetic material A is pushed up by 0, and the stick-shaped cosmetic material A in the support concave portion 47 of the holder 40 can be projected.

Here, pushing the tip of the pushing member 50 into the supporting recess 47 of the holder 40 and pushing up the stick-shaped cosmetic A by this is called "pushing up operation".

In this pushing-up operation, the stick-shaped cosmetic material A in the support recess 47 must be raised against the fixing force between the stick-shaped cosmetic material A and the holder 40. Therefore, the push-up operation requires a larger operating force than the normal operation, and the increase in the operating force makes it easier for the user to distinguish from the normal operation.

FIG. 5 shows a state in which the second engaging projection 52 abuts on the upper end of the auxiliary guide hole 43 of the holder 40.
At this time, the second engaging projection 52 also comes into contact with the upper end of the wide vertical hole 33 of the inner cylinder 20. This is the state where the stick-shaped cosmetic material A can be projected to the maximum extent.

In this stick-shaped cosmetic material feeding container, the stick-shaped cosmetic material A can be continuously ejected steplessly.

After sticking out the stick-shaped cosmetic A in this manner, the inner cylinder 2 is drawn in to draw the stick-shaped cosmetic A into the inner cylinder 20.
When 0 is rotated in the opposite direction, the holder 40 and the protruding member 50 rotate slightly horizontally, and the first engaging protrusion 42 and the second engaging protrusion 52 hit the right side wall 31b of the guide hole 31,
When the inner cylinder 20 is further rotated further, the second engaging projection 52
The protrusion member 50 moves downward due to the engagement between the protrusion member 50 and the spiral groove 13, and at the same time, the holder 40 connected to the protrusion member 50 via the stick-shaped cosmetic material A is moved downward in synchronization with the protrusion member 50. Then, the stick-shaped cosmetic material A is drawn into the inner cylinder 20.

The horizontal rotation of the holder 40 and the protruding member 50 is an extremely small angle, and does not adversely affect the retracting operability.

As described above, in this feeding container,
The first engaging protrusion 42 of the holder 40 is connected to the guide hole 3 of the inner cylinder 20.
Since it is engaged only with the spiral groove 13 of the outer cylinder 10 and not with the spiral groove 13 of the outer cylinder 10, it is not necessary to provide a horizontal portion in the spiral groove 13, and the structure of the outer cylinder 10 is simplified.

Further, since only one guide hole 31 needs to be provided in the inner cylinder 20, the structure of the inner cylinder 20 is simplified.

Furthermore, since the first engaging projection 42 of the holder 40 is not engaged with the spiral groove 13, the degree of freedom in design is widened when setting the mutual positional relationship between the holder 40 and the protruding member 50.

In the case of this delivery container, the manufacturer sets the stick-shaped cosmetic material A on the holder 40 and the ejection member 50 as follows. That is, the outer cylinder 10, the inner cylinder 20, the holder 40, and the ejection member 50 are assembled as shown in FIG. 2, an appropriate temporary cap is attached to the holder 40, and the small-diameter tubular portion 51b of the ejection member 50 is inserted from the lower opening of the ejection member 50. The holder 40 and the temporary cap are filled with liquid stick cosmetics and solidified. However, in reality, it is performed in an inverted state.

[Second Embodiment] FIG. 12 shows a small-diameter cylindrical portion 2 of an inner cylinder 20 in a second embodiment of the stick-shaped cosmetic material feeding container according to the present invention.
2 is a front view of FIG. 2, and FIG. 13 is a front view of the holder 40.

The difference between the inner cylinder 20 of this embodiment and that of the first embodiment lies in the guide hole 31. That is, the guide hole 31
Has a narrow vertical hole 38a on the upper side and a wide vertical hole 38b on the lower side, which is wider to the left than the narrow vertical hole 38a. The left side wall of the large vertical hole 38b is connected by an inclined surface 39.

The climbing slope of the inclined surface 39 is substantially equal to the climbing slope of the spiral groove 13 of the outer cylinder 10 as in the first embodiment.
Alternatively, it is set larger than the climbing gradient of the spiral groove 13.

The difference between the holder 40 of this embodiment and that of the first embodiment is the circumferential relative positional relationship between the first engaging projection 42 and the auxiliary guide hole 43. That is, in the holder 40 of this embodiment, the auxiliary guide hole 43 has the first engagement protrusion 42.
Is provided so as to be displaced to the left in the figure, and the displacement dimension thereof is substantially equal to or slightly larger than the circumferential dimension of the inclined surface 39.

The lateral width dimension of the small vertical hole 38a is such that when the second engaging projection 52 of the protruding member 50 moves upward along the inclined surface of the inclined hole 39 and the holder 40 rotates accordingly. It has a size that does not hinder the rotation of the first engagement protrusion 42 of the holder 40. The other structure is the same as that of the first embodiment.

<Normal operation: When the remaining amount of the stick-shaped cosmetic material is sufficient> Even in the normal operation of the second embodiment,
The upward movement of the holder 40 is restricted by the first engaging projection 42 hitting the upper end of the small-width vertical hole 38a of the guide hole 31, and the upward movement of the ejecting member 50 is such that the second engaging projection 52 tilts the guide hole 31. It is regulated by hitting the surface 39.

In the drawing operation of the stick-shaped cosmetic material A during the normal operation of the second embodiment, the inner cylinder 20 is replaced with the outer cylinder 10.
When rotated with respect to the holder 40 and the protruding member 50
Rotates horizontally with respect to the inner cylinder 20. This horizontal rotation is stopped when the first engaging projection 42 of the holder 40 hits the right side wall 31b of the narrow vertical hole 38a, and when the inner cylinder 20 is further rotated with respect to the outer cylinder 10 thereafter, this horizontal rotation occurs. Power is first
The engaging projection 42 acts so as to descend along the right side wall 31b of the guide hole 31, and the holder 40 is moved downward.

Here, the holder 40 and the protruding member 50 are integrally connected via the stick-shaped cosmetic material A, and the holder 4
0 and the protruding member 50 do not move relative to each other in the axial direction, so that when the holder 40 moves downward as described above, the protruding member 50 also moves downward in the inner cylinder 20 in synchronization with the holder 40. .

<Push-up operation: When the remaining amount of the stick-shaped cosmetic material is low> To push-up the stick-shaped cosmetic material A, after the second engaging projection 52 is butted against the inclined surface 39,
As in the case of the first embodiment, the operation knob 21 of the inner cylinder 20 is moved downward relative to the outer cylinder 10 against the elasticity of the bush ring 70 while preventing the outer cylinder 10 and the inner cylinder 20 from rotating relative to each other. Then, the second engaging protrusions 52 are used to climb the inclined surface 39, and the inclined surface 39 is inserted into the narrow vertical hole 38a. At this time, the holder 40 and the protruding member 50 rotate relative to the outer cylinder 10 and the inner cylinder 20 in the right direction in FIG.

At the same time, the second engaging projection 52 moves upward in the auxiliary guide hole 43 of the holder 40 and gets over the projection 44.

The subsequent steps are the same as those in the first embodiment,
After the second engaging projection 52 is inserted into the narrow vertical hole 38a, the force for pulling the inner cylinder 20 downward is removed, and the elastic restoring force of the bush ring 70 causes the inner cylinder 20 to be pulled back into the outer cylinder 10 again. After that, when the inner cylinder 20 is rotated again in the same direction as described above with the outer cylinder 10 as the non-rotating side, the second engaging projections 52 of the protruding member 50 cause the narrow vertical holes 38a of the inner cylinder 20 to rotate.
Also, the holder 40 moves upward along the auxiliary guide hole 43, that is, the protrusion member 50 moves upward in the holder 40.

As a result, as in the case of the first embodiment, the stick-shaped cosmetic material A is pushed up by the push-out member 50,
The stick-shaped cosmetic material A in the support recess 47 of the holder 40 can be projected.

As described above, according to the present invention,
The unusable portion of the stick-shaped cosmetic can be extremely reduced, and the excellent effect of being economical is exhibited.

Moreover, when the remaining amount of the stick-shaped cosmetic material is low, the stick-out amount of the stick-shaped cosmetic material can be continuously set continuously, so that the stick-out amount can be set according to the user's preference. Easy to use.

Only the second engaging projection of the protruding member is engaged with the spiral groove of the outer cylinder, and the first engaging projection of the holder is not engaged with the spiral groove, so that the structure is simplified. Moreover, the excellent effect that the degree of freedom of design is large is exhibited.

In the pulling operation after the stick-shaped cosmetic material is ejected, there is also an effect that there is no unnecessary movement and the operability is good.
