Description

[0001]
[Industrial applications]
The present invention relates to a dispensing container used for stick cosmetics such as lipstick.
[0002]
[Prior art]
In the stick-shaped cosmetic feeding container, the inner cylinder is mounted inside the outer cylinder so as to be relatively immovable in the axial direction and relatively rotatable in the circumferential direction, and the lower part of the inner cylinder exposed from the lower part of the outer cylinder is pinched and removed. When the cylinder and the inner cylinder are relatively rotated, a holder for supporting the bar-shaped cosmetic material is moved up and down in the inner cylinder so that the rod-shaped cosmetic material can be protruded and retracted from the tip of the outer cylinder.
[0003]
In such a general stick-shaped cosmetic material feeding container, when the outer cylinder and the inner cylinder are relatively rotated, the holder is continuously moved up and down between the lowest position and the highest position.
However, in the case of the stick-shaped cosmetic feeding container, it is sometimes desired to forcibly temporarily stop the upward movement of the holder at an intermediate position between the lowest position and the highest position for various reasons. One example is described below.
[0004]
There is a design requirement in the stick-shaped cosmetic material feeding container that only the stick-shaped cosmetic material is projected and exposed from the tip of the outer cylinder and the holder is not exposed from the outer cylinder.
[0005]
However, if the tip of the holder is retracted from the tip of the outer cylinder, there is no particular problem while the remaining amount of the bar-shaped cosmetic material is sufficient (that is, while the length of the bar-shaped cosmetic material is long). However, when the remaining amount of the bar-shaped cosmetic is reduced (ie, when the length of the bar-shaped cosmetic is shortened), it becomes difficult to apply the bar-shaped cosmetic, and the bar-shaped cosmetic still protrudes from the tip of the holder. There is a problem that it is uneconomical because it can not be painted even though it is present.
[0006]
Also, in the manufacturing stage, there is a case where the rod-shaped cosmetic material is loaded or mounted on the holder after the holder is assembled with the rod-shaped cosmetic material feeding container. In this case, too, the tip of the holder is retracted from the tip of the outer cylinder. If it is located, there is a problem that it is difficult to load or wear the stick-shaped cosmetic, or that it cannot be loaded or worn.
[0007]
In other words, in this type of stick-shaped cosmetic material feeding container, the holder does not want to protrude from the tip of the outer cylinder from the design point of view, and the holder is formed of the outer cylinder from the viewpoint of economical efficiency of the rod-shaped cosmetic material and ease of loading and mounting. There are conflicting demands to protrude from the tip.
[0008]
In such a case, when the holder is located at the uppermost position, the tip of the holder projects from the tip of the outer cylinder, and the upward movement of the holder is forcibly stopped at a position slightly lower than the uppermost position. If the tip of the holder is retracted from the tip of the outer cylinder, the conflicting demands can be satisfied at the same time, which is very convenient.
[0009]
In other words, when loading or mounting the bar-shaped cosmetic into the holder at the time of manufacturing, the holder can be positioned at the highest position so that the tip of the holder protrudes from the tip of the outer cylinder, and the loading and mounting of the bar-shaped cosmetic can be performed. However, when using a normal bar-shaped cosmetic, the holder can be raised and lowered between the lowermost position and the forced stop position so that the tip of the holder is not exposed from the outer cylinder, and the remaining of the bar-shaped cosmetic is This is because, when the amount is reduced, by positioning the holder at the uppermost position, the tip of the holder can be used by projecting from the tip of the outer cylinder.
[0010]
The reason for forcibly stopping the upward movement of the holder once is not limited to this.
[0011]
[Problems to be solved by the invention]
Conventionally, there has been no stick-shaped cosmetic dispensing container provided with such a mechanism.
The present invention has been made in view of such problems of the related art, and has a purpose of being able to forcibly temporarily stop the holder during the upward movement while having a simple structure, An object of the present invention is to provide a stick-shaped cosmetic dispensing container that can be moved up to the top again.
[0012]
Another object of the present invention is to provide a stick-shaped cosmetic dispensing container which has good design, can reduce the unusable portion of the stick-shaped cosmetic, is excellent in economic efficiency, and can be easily loaded and mounted in the manufacturing stage. Is to provide.
[0013]
[Means for Solving the Problems]
The present invention employs the following means in order to solve the above problems.
[Summary of the present invention]
The stick-shaped cosmetic feeding container of the present invention includes (a) an outer cylinder, (b) an inner cylinder, and (c) a holder, and the holder is moved inside by rotating the outer cylinder and the inner cylinder relative to each other. It moves up and down inside the cylinder. Hereinafter, each component will be described.
[0014]
<Outer cylinder>
The outer cylinder has a spiral groove on its inner peripheral surface.
[0015]
<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 of the inner cylinder.
[0016]
In this guide hole, an inclined surface that inclines in the same direction as the inclined direction of the spiral groove when the outer cylinder is seen through from the outside, in the middle of the upward guide wall that guides the engagement protrusion of the holder when the holder is moved upward. Is provided. Note that this inclined surface may be linear or curved.
[0017]
<holder>
The holder is inserted into the inner cylinder so as to be able to move up and down, and supports the base of the stick-shaped cosmetic. An engaging projection is provided on the peripheral wall of the holder so as to penetrate the guide hole of the inner cylinder and slidably engage with the spiral groove of the outer cylinder. The holder moves up and down in the inner cylinder by rotating the outer cylinder and the inner cylinder relatively.
[0018]
In the stick-shaped cosmetic feeding container of the present invention, when the holder moves upward and the engaging projection abuts on the inclined surface of the guide hole, the upward movement of the holder is forcibly stopped. When the inner cylinder is relatively moved in a direction of pulling out the lower part of the outer cylinder with the engagement projection abutting the inclined surface, the engagement projection climbs up the inclined surface. Thereafter, when the outer cylinder and the inner cylinder are rotated relative to each other, the engagement projection can move up the guide hole again, and the holder can move up further in the inner cylinder (corresponding to claim 1).
[0019]
Moreover, in the stick-shaped cosmetic material feeding container of the present invention, the stroke of the holder can be set as follows. That is, in a state in which the engagement protrusion abuts against the inclined surface and the holder is forcibly stopped, the tip of the holder is retracted and positioned in the outer cylinder, and the outer cylinder and the inner cylinder are relatively moved in the axial direction. After the engagement protrusion is used to move up the inclined surface, the holder is moved up again so that the holder is positioned at the uppermost position, and the tip of the holder is made to protrude more outward than the tip of the outer cylinder. (Corresponds to item 2).
[0020]
In the stick-shaped cosmetic feeding container of the present invention, it is preferable to provide an elastic member for urging the inner cylinder upward between the outer cylinder and the inner cylinder (corresponding to claim 3). In this case, the outer cylinder and the inner cylinder do not rattle. However, the present invention can be realized without providing an elastic member.
[0021]
The slope of the inclined surface of the guide hole is preferably set to be substantially equal to or greater than the slope of the spiral groove of the outer cylinder (corresponding to claim 4). When a gradient is set in such a relationship, the engagement protrusion can be made to reliably climb the inclined surface.
[0022]
[Action]
<Operation of the present invention>
When the outer cylinder and the inner cylinder are relatively rotated, the holder moves upward in the inner cylinder, and the stick-shaped cosmetic projects from the outer cylinder. During the upward movement of the holder, the holder can continuously move upward in the inner cylinder until the engagement protrusion abuts on the inclined surface of the guide hole.
[0023]
When the engaging projection abuts on the inclined surface of the guide hole, the holder is forcibly stopped, and the holder cannot be further moved upward by the normal upward operation.
When the inner cylinder is relatively moved in the direction of pulling out from the lower part of the outer cylinder in a state where the engagement projection is abutted on the inclined surface, a large upward force acts on the engagement projection via the spiral groove of the outer cylinder, and as a result, The engagement protrusion moves up along the inclined surface and climbs up the inclined surface.
[0024]
Thereafter, when the outer cylinder and the inner cylinder are rotated relative to each other, the engagement protrusion moves upward in the guide hole located above the inclined surface, and as a result, the holder moves upward to the highest position.
[0025]
Also, when the engaging projection hits the inclined surface, the tip of the holder is retracted into the outer cylinder, and when the holder is at the highest position, the tip of the holder projects outward from the tip of the outer cylinder. In the case where the position is set at the position shown in FIG.
[0026]
That is, when loading or attaching the stick-shaped cosmetic to the holder at the time of manufacture, the holder is positioned at the highest position and the tip of the holder is projected from the tip of the outer cylinder. This makes it possible to easily load or attach the stick-shaped cosmetic.
[0027]
When using a bar-shaped cosmetic, the holder is usually raised and lowered between the lowest position and the forced stop position. When the holder is located between them, the tip of the holder is retracted into the outer cylinder and is not exposed, so that the appearance is good.
[0028]
On the other hand, when the remaining amount of the bar-shaped cosmetic material is low, the holder is positioned at the highest position and the tip of the holder is projected from the tip of the outer cylinder. Thereby, it becomes easy to apply the bar-shaped cosmetic even when the remaining amount is small, and the unusable portion of the bar-shaped cosmetic can be reduced as much as possible.
[0029]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings of FIGS.
[0030]
[First embodiment]
1 to 5 are cross-sectional views of a stick-shaped cosmetic dispensing container (hereinafter referred to as a dispensing container) 1 according to a first embodiment of the present invention.
[0031]
The feeding container 1 includes an outer cylinder 10, an inner cylinder 20, a holder 40, and a bush ring 70.
The outer cylinder 10 is composed of a hollow cylindrical metal cosmetic cylinder 11 having an open top and bottom, and a cylindrical plastic spiral groove cylinder 12 fixed inside the cosmetic cylinder 11. The front end of the groove tube 12 is located below the front end of the decorative tube 11 by a predetermined dimension.
[0032]
A spiral groove 13 is formed on the inner peripheral surface of the spiral groove cylinder 12. FIG. 7 is a front view showing a part of the inner peripheral surface of the spiral groove tube 12 when the spiral groove tube 12 is viewed from the inside. When viewed from this viewpoint, the spiral groove 13 has an upward slope. ing.
[0033]
The inner cylinder 20 is inserted inside the outer cylinder 10. FIG. 8 is a front view of the inner cylinder 20. The inner cylinder 20 is made of plastic and has a hollow cylindrical shape with an open top and bottom. The lower end of the inner cylinder 20 is provided with a slightly large-diameter operation knob 21, and a small-diameter cylinder (peripheral wall) 22 extends upward from the operation knob 21. In addition, a retaining ring 23 is provided on the leading edge of the small-diameter cylindrical portion 22.
[0034]
Guide holes 31 are provided one by one in the small-diameter cylindrical portion 22 at 180 degrees apart in the circumferential direction.
The guide hole 31 includes a starting lateral groove 32 extending in the circumferential direction along the lower end of the small-diameter cylindrical portion 22, a terminal lateral groove 33 extending in the peripheral direction along the vicinity of the retaining ring 23, and a left end and a terminal lateral groove of the starting lateral groove 32. And a vertical groove 34 connecting the right end of the shaft 33.
[0035]
The right wall surface of the vertical groove 34 constitutes a lower movement guide wall 35 for guiding an engagement protrusion 42 of the holder 40 described later to move downward, and is formed in a straight line.
The left wall surface of the vertical groove 34 constitutes an upper guide wall 36 for guiding the engagement protrusion 42 of the holder 40 to move upward. The upper moving guide wall 36 is formed from a left end of the starting lateral groove 32 and extends straight up to the vicinity of the terminal lateral groove 33. The first linear part 36 a is connected to the upper end of the first linear part 36 a, and the width of the vertical groove 34 is shifted to the left. A width extending portion 36b to be widened, an inclined surface 36c connected to an upper end of the width extending portion 36b and gradually rising to the right to gradually narrow the width of the vertical groove 34, and a terminal lateral groove 33 extending straight upright from the upper end of the inclined surface 36c. And a second linear portion 36d connected to the second linear portion 36d.
[0036]
The slope of the inclined surface 36c is substantially equal to the slope of the spiral groove 13 of the outer cylinder 10 or greater than the slope of the spiral groove 13.
[0037]
The inner cylinder 20 is inserted into the outer cylinder 10 at the front end, the tip is located slightly below the tip of the outer cylinder 10, the operation knob 21 is projected from the lower part of the outer cylinder 10, and the operation knob 21 A step portion 24 provided at the boundary between the outer cylinder 10 and the small-diameter cylinder portion 22 is attached to the lower edge of the outer cylinder 10 so as to be rotatable relative to the outer cylinder 10 in the circumferential direction.
[0038]
A bush ring made of plastic that urges the inner cylinder 20 upward is provided between the tip of the spiral groove cylinder 12 of the outer cylinder 10 and the retaining ring 23 of the inner cylinder 20 outside the inner cylinder 20. An elastic member 70 is interposed.
[0039]
FIG. 10A is a plan view of the bush ring 70, and FIG. 10B is a front view thereof. The bush ring 70 has an annular shape, and three non-deformable connecting portions 71 and three deformable portions 72 are provided alternately in the circumferential direction. The deformable portion 72 is curved downward substantially in a U-shape when viewed from the front, and protrudes below the non-deformed connecting portion 71.
[0040]
The deformable portion 72 is elastically compressively deformable in the axial direction (the vertical direction in FIG. 10B).
As shown by the broken line in FIG. 4, the bush ring 70 is sandwiched between the tip of the spiral groove tube 12 and the retaining ring 23 with the deformable portion 72 almost in a deformed state. The lower edge of the outer cylinder 10 abuts the step 24 of the inner cylinder 20.
[0041]
Then, as shown by a broken line in FIG. 3, the inner cylinder 20 can be slightly pulled out below the outer cylinder 10 by elastically deforming the deformable portion 72 of the bush ring 70. In other words, when the user holds the outer cylinder 10 with one hand and holds the operation knob 21 of the inner cylinder 20 with the other hand and pulls down, the deformable portion 72 of the bush ring 70 can be elastically compressed and deformed. The inner cylinder 20 can be pulled out. When the operation knob 21 is released after being pulled out, the inner cylinder 20 is automatically retracted by the restoring force of the bush ring 70.
[0042]
The shape of the bush ring 70 is not limited to the shape shown in FIG. 10, and may have any shape as long as it has a function of urging the inner cylinder 20 upward as described above. .
[0043]
11 and 12 show other examples of the bush ring 70. The bush ring 70 in FIG. 11 is configured by connecting two upper and lower rings 73 with three spiral arms 74, and the spiral arm 74 elastically deforms to expand and contract the distance between the rings 73. I have. The bush ring 70 shown in FIG. 12 is formed of a normal coil spring.
[0044]
In the case of each of these bush rings 70, they are installed outside the inner cylinder 20 and between the tip of the spiral groove cylinder 12 and the latch ring 23 of the inner cylinder 20. However, the present invention is not limited to this. The point is that the inner cylinder 20 only needs to be arranged so as to be able to urge the cylinder upward.
[0045]
A plastic holder 40 is inserted inside the inner cylinder 20 so as to be able to move up and down. FIG. 9 is a front view of the holder 40. The holder 40 has a hollow cylindrical shape with an open top and bottom. The base of the cosmetic bar A is fixed inside the holder 40 to support the cosmetic bar A. A plurality of flanges 43 are protruded from the inner surface of the peripheral wall 41, and the flanges 43 firmly fix the stick-shaped cosmetic A to the holder 40.
[0046]
On the outer surface of the peripheral wall portion 41 of the holder 40, engagement protrusions 42 are provided one by one at a distance of 180 degrees in the circumferential direction. The engagement projection 42 is slidably engaged with the spiral groove 13 of the outer cylinder 10 by passing through the guide hole 31 of the inner cylinder 20, and by rotating the outer cylinder 10 and the inner cylinder 20 relatively. The holder 40 can be moved up and down in the inner cylinder 20, and the stick-shaped cosmetic A can be made to protrude and retract from the tip of the outer cylinder 10.
[0047]
FIG. 2 shows a state where the holder 40 is positioned at the lowermost position. Hereinafter, this state will be described as an initial state.
In the initial state, the engagement protrusion 42 of the holder 40 is located at the right end of the starting end lateral groove 32 of the guide hole 31 of the inner cylinder 20. In this initial state, not only the inner cylinder 20 but also the holder 40 and the bar-shaped cosmetic A do not protrude from the tip of the outer cylinder 10.
[0048]
Next, the operation of the feeding container will be described.
<Normal dispensing operation: When there is enough remaining stick-shaped cosmetic>
From the initial state shown in FIG. 2, when the outer cylinder 10 is set to the non-rotation side and the inner cylinder 20 is rotated with the operation knob 21, while the engaging projection 42 is in contact with the upper side of the starting end lateral groove 32, the holder 40 is Since the upward movement is restricted, the engagement protrusion 42 relatively moves horizontally toward the left end of the starting end lateral groove 32, that is, the holder 40 relatively horizontally rotates inside the inner cylinder 20.
[0049]
When the engagement protrusion 42 reaches a position where the engagement protrusion 42 comes into contact with the upper left edge of the start end lateral groove 32, the upward movement restriction of the holder 40 is released, and the holder 40 starts to move upward. When the inner cylinder 20 and the holder 40 are stopped from rotating relative to each other when the first linear portion 36a of the upward movement guide wall 36 is abutted, the engagement protrusion 42 slides on the first linear portion 36a to move upward. 40 only moves upward in the inner cylinder 20. Due to the upward movement of the holder 40, the stick-shaped cosmetic A protrudes from the tip of the outer cylinder 10 and is exposed.
[0050]
At this time, the holder 40 does not rotate relative to the inner cylinder 20, but rotates only relative to the outer cylinder 10.
By the rotation operation of the inner cylinder 20, the engagement protrusion 42 of the holder 40 moves up and down the first linear portion 36a and further moves continuously to the width expanding portion 36c. When the engagement protrusion 42 moves from the upper end of the first straight portion 36a to the width expansion portion 36b, the holder 40 rotates relative to the inner cylinder 20 by the width expansion dimension of the vertical groove 34. Then, the engagement protrusion 42 abuts on the left end edge of the width expansion portion 36b, and comes into contact with the inclined surface 36c almost at the same time.
[0051]
FIG. 6 is an enlarged view showing the positional relationship between the guide hole 31 and the engagement protrusion 42 at this time. In the drawing, a two-dot chain line indicates the spiral groove 13 that engages with the engagement protrusion 42, From the perspective of FIG.
[0052]
In this state, even if the outer cylinder 10 is set to the non-rotating side and the inner cylinder 20 is rotated in the arrow X direction in the figure, the engagement protrusion 42 is held in a state of being hooked on the inclined surface 36c, and the holder 40 is And the inner cylinder 20 cannot rotate and cannot move upward.
[0053]
More specifically, the engagement protrusion 42 sandwiched between the wall surface of the spiral groove 13 and the inclined surface 36c of the guide hole 31 has a direction of descending along the inclined surface 36c by the rotational force of the inner cylinder 20 (see FIG. Middle arrow Z ₁ Direction), and as a result, the engagement projection 42 cannot climb over the inclined surface 36c.
[0054]
As described above, the holder 40 is forcibly stopped when the engagement projection 42 abuts on the inclined surface 36c, and this is not necessary in a normal feeding operation in which the inner cylinder 20 is simply rotated relative to the outer cylinder 10. As described above, the holder 40 cannot be moved upward. Hereinafter, this holder position will be referred to as a middle forced stop position.
[0055]
FIG. 1 shows this state. At this time, the position of the inclined surface 36c is set so that the tip of the holder 40 is retracted from the tip of the outer cylinder 10. That is, when the holder 40 is located between the lowermost position and the forced stop position halfway, the tip of the holder 40 is always retracted into the outer cylinder 10 and located. Therefore, in the use state at the time of the normal feeding operation, only the rod-shaped cosmetic A protrudes from the tip of the outer cylinder 10, and the appearance is very good and the design is excellent.
[0056]
In addition, when pulling in the stick-shaped cosmetic A, the outer cylinder 10 and the inner cylinder 20 are relatively rotated in the opposite direction to that described above. Then, the holder 40 slightly rotates horizontally, and the engagement protrusion 42 abuts on the lower moving guide wall 35 of the guide hole 31, and then slides along the lower moving guide wall 35 to move downward, whereby the holder 40 is moved. It will move down.
[0057]
<Fill-out operation when remaining amount is low: When remaining amount of stick-shaped cosmetics is low>
When the remaining amount of the bar-shaped cosmetic material A becomes small and the amount of protrusion of the bar-shaped cosmetic material A protruding from the tip of the outer cylinder 10 becomes short even when the holder 40 is positioned at the forced stop position on the way, the following operation is performed. I do.
[0058]
First, the holder 40 is moved up to the forced stop position halfway by the above-described normal feeding operation, and the engagement protrusion 42 is abutted against the inclined surface 36c.
Next, the operation knob 21 of the inner cylinder 20 is pulled downward while preventing the outer cylinder 10 and the inner cylinder 20 from rotating relative to each other, and the inner cylinder 20 is moved relative to the outer cylinder 10 against the elasticity of the bush ring 70. 6 in the direction of arrow Y in FIG.
[0059]
Then, the engagement protrusion 42 of the holder 40 has a direction of raising the inner cylinder 20 along the inclined surface 36c by a force for pulling the inner cylinder 20 downward (arrow Z in FIG. 6). ₂ Direction), and as a result, the engagement projection 42 is sandwiched between the inclined surface 36c and the wall surface of the spiral groove 13 and the arrow Z ₂ Move in the direction. At this time, the holder 40 rotates in the arrow X direction with respect to the outer cylinder 10 and the inner cylinder 20.
[0060]
In this manner, the engaging projection 42 of the holder 40 is moved up the inclined surface 36c and brought into contact with the second linear portion 36d. FIG. 3 shows this state.
[0061]
Next, when the force pulling the inner cylinder 20 downward is removed, the inner cylinder 20 is pulled back into the outer cylinder 10 again by the elastic restoring force of the bush ring 70 as shown in FIG. However, at this time, the engaging projection 42 is not pulled back to the inclined surface 36c or the width expanding portion 36b, and is kept in a state of contacting the second linear portion 36d. In the state shown in FIG. 4, the tip of the holder 40 slightly protrudes from the tip of the outer cylinder 10.
[0062]
Thereafter, when the inner cylinder 20 is rotated again in the same direction as in the case of the above-described normal feeding operation with the outer cylinder 10 as the non-rotating side, the engagement protrusion 42 slides on the second linear portion 36d to move upward. As a result, the holder 40 moves upward in the inner cylinder 20 again, and the dimension of the holder 40 projecting from the tip of the outer cylinder 10 gradually increases.
[0063]
By the rotation operation of the inner cylinder 20, the engagement protrusion 42 of the holder 40 climbs up and down the second linear portion 36d, continuously enters the terminal lateral groove 33, and abuts on the upper side of the terminal lateral groove 33. Thus, the upward movement of the holder 40 is prevented.
[0064]
Thereafter, as a result of the engagement protrusion 42 sliding along the upper side of the terminal vertical groove 33 and relatively moving toward the left end, the holder 40 rotates relatively horizontally with respect to the inner cylinder 20. Then, as shown in FIG. 5, when the engagement protrusion 42 abuts on the left end of the terminal lateral groove 33, the relative horizontal rotation of the holder 40 is also prevented. This is the end point of the holder 40 and the highest.
[0065]
When the engaging projection 42 of the holder 40 is positioned higher than the inclined surface 36c of the guide hole 31 in this manner, the tip of the holder 40 can be made to protrude from the tip of the outer cylinder 10; Can be easily applied to the stick-shaped cosmetic A having a reduced amount of protrusion from the base. Further, when the remaining amount of the bar-shaped cosmetic material A becomes small, the bar-shaped cosmetic material A contained in the holder 40 is also very easy to use when wiped off with a lip brush.
[0066]
After the holder 40 is positioned at the uppermost position, the rod-shaped cosmetic A is drawn into the inner cylinder 20 in the same manner as the operation of pulling the rod-shaped cosmetic A after the normal feeding operation. Rotates in the direction opposite to the direction of the feeding operation.
[0067]
Then, the holder 40 rotates slightly horizontally relative to the inner cylinder 20, and when the engagement protrusion 42 abuts against the lower movement guide wall 35 of the guide hole 31, the relative rotation of the holder 40 is prevented. As a result, the holder 40 moves down by sliding down the guide wall 35. Then, when the engagement protrusion 42 has descended the lower movement guide wall 35, it enters the start end lateral groove 32, stops against the right end thereof.
[0068]
<When loading stick-shaped cosmetics>
In the feeding container 1, in the manufacturing process, after the outer cylinder 10, the inner cylinder 20, the holder 40, and the bush ring 70 are assembled, the loading operation of the stick-shaped cosmetic A can be performed very easily.
[0069]
That is, as shown in FIG. 13, by positioning the holder 40 at the uppermost position, the tip of the holder 40 is made to protrude as much as possible from the tip of the outer cylinder 10. The temporary cap 50 is attached. Then, the feeding container 1 is inverted, and the liquid rod-shaped cosmetic material is injected into the holder 40 and the temporary cap 50 from the bottom opening 25 of the operation knob 21 of the inner cylinder 20.
[0070]
When the temporary cap 50 is removed and the holder 40 is returned to the lowermost position when the bar-shaped cosmetic material A has solidified, the bar-shaped cosmetic material A is stored in the outer cylinder 10 and the inner cylinder 20 as shown in FIG.
[0071]
As described above, when the stick-shaped cosmetic is filled, the tip of the holder 40 can be sufficiently protruded from the tip of the outer cylinder 10, so that the temporary cap 50 can be attached to and detached from the holder 40 very easily, and the filling operation can be performed. Can be easily done.
[0072]
Also, when the stick-shaped cosmetic A solidified in a stick shape is inserted into the holder 40 and attached, the tip of the holder 40 can be made to protrude from the tip of the outer cylinder 10, and the attaching operation is easy.
[0073]
[Second embodiment]
FIG. 14 is a front view of the inner cylinder 20 in the second embodiment of the stick-shaped cosmetic dispensing container of the present invention.
[0074]
The difference between the inner cylinder 20 of this embodiment and that of the first embodiment lies in the guide hole 31. That is, in this embodiment, the upper moving guide wall 37, which is the left wall surface of the guide hole 31, gradually narrows the width of the lower first straight portion 37a, the upper second straight portion 37c, and the guide hole 31. As described above, the upper surface of the first linear portion 37a and the inclined surface 37b connecting the upper end of the second linear portion 37c. Further, the lower moving guide wall 38 of the guide hole 31 is formed in a straight line.
[0075]
As in the first embodiment, the uphill slope of the inclined surface 37b is substantially equal to the uphill slope of the spiral groove 13 of the outer cylinder 10, or is larger than the uphill slope of the spiral groove 13. The other configuration is exactly the same as that of the first embodiment.
[0076]
The same operation and effect as the supply container 1 of the first embodiment can be obtained in the supply container 1 using the inner cylinder 20 of the second embodiment.
That is, the holder 40 is forcibly stopped halfway when the engagement protrusion 42 abuts on the inclined surface 37b of the guide hole 31 during the upward movement. When the holder 40 is located at the forced stop position on the way, the holder 40 cannot be further moved upward merely by rotating the inner cylinder 20 with respect to the outer cylinder 10.
[0077]
Then, after the holder 40 is stopped at the forced stop position on the way, by pulling the inner cylinder 20 downward, the engagement protrusion 42 can be made to climb the inclined surface 37b, and thereafter, the inner cylinder 20 is further moved. When rotated with respect to the outer cylinder 10, the engagement protrusion 42 slides on the second linear portion 37c and moves upward. As a result, the holder 40 can be raised until the engagement protrusion 42 comes into contact with the upper edge of the guide hole 31. The time when the engaging projection 42 abuts on the upper edge of the guide hole 31 is the end point of the holder and is the highest position.
[0078]
When the inner cylinder 20 is rotated in the opposite direction, the engagement projection 42 slides down the guide hole 38 of the guide hole 31 to move downward, and as a result, the holder 40 moves downward. Is the same as
[0079]
Also in the case of the second embodiment, when the holder 40 is located between the lowermost position and the halfway forced stop position, the tip of the holder 40 is retracted from the tip of the outer cylinder 10 so that the middle When located between the stop position and the uppermost position, the tip of the holder 40 can be made to protrude from the tip of the outer cylinder 10.

【The invention's effect】
As described above, according to the present invention, the inner cylinder is attached to the outer cylinder so as to be slightly movable in the axial direction, and the spiral groove of the outer cylinder is provided in the middle of the upper moving guide wall in the guide hole of the inner cylinder. An excellent effect of being able to forcibly stop the holder halfway with a very simple structure that simply adds the structure of providing an inclined surface inclined in the same direction to the structure of a conventional general stick-shaped cosmetic dispensing container. Is played.
[0081]
Further, when the engaging projection of the holder abuts against the inclined surface of the guide hole, the tip of the holder is retracted into the outer cylinder, and when the holder is located at the highest position, the tip of the holder is positioned at the tip of the outer cylinder. The following effects can be obtained when the first position is also projected outward.
[0082]
After assembling the rod-shaped cosmetic material feeding container, the operation of loading or attaching the rod-shaped cosmetic material to the holder can be extremely easily performed.
Also, if the normal upper movement limit of the holder when the stick-shaped cosmetic is drawn out and used is set to a forced stop position in the middle, in the normal use state, only the stick-shaped cosmetic protrudes from the tip of the outer cylinder and is exposed. Good appearance and rich design.
[0083]
Furthermore, if the holder is positioned at the highest position when the remaining amount of the bar-shaped cosmetic material is low, the tip of the holder can be protruded from the tip of the outer cylinder, so that it is easy to apply and use of the bar-shaped cosmetic material. It is economical because the impossible parts can be reduced as much as possible.
