Description

Stick-shaped cosmetic container

Technical Field

The present invention relates to a container for containing stick-shaped cosmetics such as lipstick, and more particularly, to a stick-shaped cosmetic container capable of screwing (feeding) stick-shaped cosmetics from a part of the container.

Background

Conventionally, as a container for storing a stick type cosmetic such as lipstick, for example, a container is known which can be unscrewed from a part of the container by a cosmetic holding portion holding the stick type cosmetic as shown in

patent documents

1 and 2. In such a stick-type cosmetic container, and further in a stick-type cosmetic container not subjected to the above-described unscrewing, it is uneconomical and wasteful to dispose of the stick-type cosmetic container as it is after almost all of the stick-type cosmetic has been used up. In addition, in the case of using a general stick cosmetic container, it is impossible to completely use up the stick cosmetic in normal use, and the term "use up" means that the portion held by the cosmetic holder is left and the other portions are almost completely used up.

Therefore, recently, in order to cope with the above-mentioned problems of being uneconomical and wasting resources, a stick cosmetic is also provided as a so-called "refill". That is, even if the stick cosmetic is used up, another stick cosmetic is used instead as the refill, and the stick cosmetic container can be continuously used, so that the above-described problem can be avoided. In the above-described cosmetic stick container, the cosmetic holder holding the cosmetic stick is generally rotated out, and therefore, the cosmetic stick is usually replaced together with the cosmetic holder. However, not limited to this, it is also conceivable to replace only the stick-shaped cosmetic by reusing the cosmetic holder.

Patent documents

1 and 2 show examples of stick-shaped cosmetic containers to which stick-shaped cosmetics as refill are applied. More specifically, patent document 1 discloses an alternative lipstick in which a base is provided in addition to a stick-shaped lipstick, the base includes an attachment/fixation means for attaching and fixing the lipstick to one end, a fitting means which is capable of being coupled to and decoupled from an end portion of a lipstick case (lip case) and which is capable of transmitting rotation from the lipstick case to the other end by the coupling, and a slit for inserting a detachable arm used for an operation of coupling and decoupling the lipstick to and from the lipstick case, in an intermediate portion.

Further, patent document 2 shows a lipstick container comprising: a lipstick holder to which a stick-shaped lipstick is attached; a container body provided with an in-out unit for moving the lipstick support up and down; the middle shell is arranged in the container body; and a cap body which is freely jointed with the container body and closes the end part of the lipstick.

The stick cosmetic as the refill is often sold separately from an original stick cosmetic container used for makeup or in a state of being held by a cosmetic holding portion. In this case, the stick-type cosmetic container used for makeup is not protected, and therefore, it is desirable to store the stick-type cosmetic container in a case different from the container for protection.

Patent documents

1 and 2 also show a case-shaped unit that can protect a stick cosmetic by covering it. For example, the detachable arm described in patent document 1 is formed in a substantially 1-side-open box-shaped housing, and can be protected by covering a bar-shaped lipstick. The cap body disclosed in patent document 2 is formed in a case shape including a bottomed tube, and can be fixed to the container body in a state of covering the stick-shaped lipstick to protect the lipstick.

Disclosure of Invention

Problems to be solved by the invention

However, in the alternative lipstick disclosed in patent document 1, since the base and the lipstick are screwed to each other in order to hold the lipstick on the base, there is a problem that the lipstick is easily detached from the base due to loosening of the screw. In this alternative lipstick, in order to connect the base to the lipstick case, the tapered portion formed in the base is pushed into the end portion of the lipstick case to be fitted, and therefore, the problem that the base and hence the lipstick fixed to the base are easily detached from the lipstick case is recognized.

Further, in the lipstick case shown in patent document 2, in order to remove the used lipstick from the lipstick holder, the base of the lipstick is pushed by a pin inserted into the lipstick holder from an end opening of the lipstick holder, or the lipstick is removed from the lipstick holder by being directly pinched by a fingertip, so that it is recognized that the removal work of the lipstick is extremely troublesome.

On the other hand, the case-like attachment/detachment arm shown in patent document 1 is fixed to the base by inserting 1 notch formed in the bottom plate into the slit of the base, and therefore, in a state where the arm is fixed to the base to protect the lipstick, the arm is easily detached from the base unintentionally. The same problem is recognized in the case-like cap body shown in patent document 2. That is, since the cap body is fixed to the container body by fitting, the cap body is easily unintentionally detached from the container body in a state where the cap body is fixed to the container body to protect the lipstick.

The present invention has been made in view of the above circumstances, and an object thereof is to enable a cosmetic holder holding a stick type cosmetic to be easily and reliably engaged with and disengaged from a rotation mechanism in a stick type cosmetic container in which the cosmetic holder holding the stick type cosmetic can be rotated out from a part of the container.

Further, an object of the present invention is to provide a stick type cosmetic container that can reliably cover and adhere to a cosmetic holding portion that holds a stick type cosmetic without an unintentional removal of a case that protects the stick type cosmetic, in the stick type cosmetic container that can unscrew the cosmetic holding portion holding the stick type cosmetic from a part of the container.

Means for solving the problems

The present invention relates to a stick-shaped cosmetic container, comprising:

a cosmetic holder for holding one end of a stick-shaped cosmetic on the upper part;

an upper and lower movable member which is engaged with the cosmetic holding portion and has at least 1 convex portion facing the outer periphery on the outer peripheral surface;

a middle cylinder which is composed of a cylindrical component for accommodating the upper and lower movable parts and the cosmetic holding part, and is provided with a gap at least a part of which extends in the cylinder axial direction and receives the convex part; and

a screwing-out mechanism for relatively moving the upper and lower movable parts in the cylinder axial direction with respect to the middle cylinder in a state where the projection is guided by the slit,

the notch narrowing portion is aligned with the slit and is elastically deformable to allow the protrusion to escape from the notch to the opening side in a state where the upper and lower movable parts are moved to the vicinity of the top dead center with respect to the middle tube.

Preferably, in the above-described configuration, the structure is further configured,

the slit of the middle cylinder is bent towards the circumferential direction of the middle cylinder at the upper end,

in a state where the upper and lower movable parts are moved to the vicinity of the top dead center with respect to the middle cylinder, the convex portion of the upper and lower movable parts is located at a bent portion of the slit, and the notch narrowing portion is aligned with a portion of the slit extending in the axial direction of the middle cylinder.

In the cosmetic stick container according to the present invention, it is preferable that,

the upper and lower movable parts have a through hole extending in the vertical direction at the center,

the cosmetic holding section has a portion which is inserted through the through hole of the upper and lower movable components while being in close contact with the peripheral wall of the through hole, inside the portion which grips the upper and lower movable components from the outside of the periphery.

Another stick-shaped cosmetic container according to the present invention includes:

a cosmetic holder which holds one end of a stick-shaped cosmetic at the upper part and has at least 1 convex part facing the outer side of the outer peripheral surface;

an upper and lower movable component engaged with the cosmetic holding portion via the convex portion;

a screwing-out mechanism for relatively moving the upper and lower movable parts in the cylinder axial direction with respect to the middle cylinder in a state where the convex portion is guided by the slit,

it is characterized in that the preparation method is characterized in that,

a slit formed in the middle tube in a range where the convex portion can be pulled out upward from the upper end of the middle tube,

the engagement can be released when the upper and lower movable parts are in the upper and lower positions where the convex portions of the joined cosmetic holding portions are pulled out upward from the upper end of the middle tube, and the engagement is made difficult to release when the upper and lower movable parts are in the upper and lower positions where the convex portions of the joined cosmetic holding portions are accommodated in the slits.

In the above-described another stick-type cosmetic container, it is preferable that the stick-type cosmetic container is configured such that,

the upper and lower movable parts have a cylindrical portion provided with a groove for receiving the projection from above,

the cosmetic holder is gripped from the outer circumferential side by the cylindrical portion and the movement of the cylindrical portion to the outer circumferential side is restricted by the middle cylinder, so that it is difficult to release the engagement,

the engagement can be released by the cylindrical portion being able to move outward in the circumferential direction as the cylindrical portion is pulled out upward from the upper end of the middle tube.

Further, another stick-type cosmetic container according to the present invention includes:

an upper and lower movable member having at least 1 convex portion facing the outer periphery on the outer peripheral surface and engaged with the cosmetic retaining portion via the convex portion;

a middle cylinder which is composed of a cylindrical component for accommodating the upper and lower movable parts and the cosmetic holding part, and is provided with a gap at least a part of which extends in the cylinder shaft direction and receives the convex part; and

it is characterized in that the preparation method is characterized in that,

the engagement can be released when the upper and lower movable parts are in the upper and lower positions where the convex portion is pulled out upward from the upper end of the middle tube, and the engagement is made difficult to release when the upper and lower movable parts are in the upper and lower positions where the convex portion is accommodated in the slit.

In the above-described further stick-type cosmetic container, it is preferable that the stick-type cosmetic container is configured such that,

the cosmetic holder has a cylindrical portion provided with a groove for receiving the projection from below,

the upper and lower movable parts are held from the outer side of the circumference by the cylindrical portion and the movement of the cylindrical portion to the outer side of the circumference is restricted by the middle cylinder, so that it is difficult to release the engagement,

In each of the stick-type cosmetic containers of the present invention described above, it is preferable that,

the cosmetic container further comprises a case that covers the stick-shaped cosmetic protruding from the cosmetic holder from the outside over the entire length, and is attached to the cosmetic holder via a joint that suppresses movement of the case in the longitudinal direction and the thickness direction of the cosmetic.

Preferably, the case as described above is formed of a member that can be elastically deformed when it is attached to the cosmetic holding portion by covering,

the engaging portion engages the elastically deformed housing and the cosmetic retaining portion.

Further, it is preferable that the housing is configured to be movable from a state of being covered and adhered to the cosmetic holding portion to one of the thickness directions of the stick-shaped cosmetic held by the cosmetic holding portion, thereby releasing the covering and adhering.

Effects of the invention

In the stick-type cosmetic container according to the present invention, since the engagement between the upper and lower movable elements and the cosmetic holding portion can be released when the upper and lower movable elements are moved to a position near the top dead center with respect to the inner tube and the engagement is difficult to release when the upper and lower movable elements are at other upper and lower positions, the cosmetic holding portion can be removed for replacement by a simple manual operation only after the upper and lower movable elements are moved to the position near the top dead center, that is, by an operation of pulling out the cosmetic holding portion from the upper and lower movable elements. Further, in the stick-shaped cosmetic container according to the present invention, since the upper and lower movable members are configured as described above, the cosmetic holder and the upper and lower movable members can be reliably and stably maintained in the joined and integrated state only by moving the upper and lower movable members to positions other than the vicinity of the upper dead center.

In the stick type cosmetic container according to the present invention, the case for protecting the stick type cosmetic is attached to the cosmetic holder in a covering manner in a state in which the movement of the stick type cosmetic in the longitudinal direction and the thickness direction is suppressed, and therefore, the attachment is reliably achieved, and the case is not detached from the cosmetic holder unintentionally.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 and 2 are perspective views showing a state in which a lipstick 1 as an example of a stick type cosmetic contained in the stick type cosmetic container of the present invention is held by a cosmetic holding portion 2. Fig. 3 is a perspective view showing a stick-shaped cosmetic container according to embodiment 1 of the present invention, in which the lipstick 1 is housed. First, a lipstick 1 will be described with reference to fig. 1 and 2. The lipstick 1 is, for example, a so-called "refill" that is used by being replenished to a stick-type cosmetic container when the lipstick that has been stored in the stick-type cosmetic container described later is used up. The lipstick 1 is formed in a bar shape as shown in fig. 1, and has one end (lower end in the figure) held by the cosmetic holder 2, for example, and the case 3 detachably covers the cosmetic holder 2. The lipstick 1, the cosmetic holding portion 2, and the case 3 in the above-described states are stored in, for example, a transparent bottomed square tube-shaped refill storage case 4 (the state of fig. 2), and are sold or the like.

The cosmetic holder 2 and the case 3 are formed of, for example, a biodegradable polymer PHBH (registered trademark), ABS (acrylonitrile butadiene styrene) resin, or the like. PHBH is a particularly preferable material from the viewpoint of environmental protection. On the other hand, the refill housing case 4 is formed of, for example, a PE (polyethylene) resin. However, the materials of the cosmetic holding portion 2, the case 3, and the refill housing case 4 are not limited to these, and particularly, the case 3 and the refill housing case 4 are preferably formed of paper in order to reduce the amount of resin used.

As shown in fig. 3 (a), the cosmetic holder 2 taken out of the refill housing case 4 is joined and integrated with the vertically movable part 20 in the substantially cylindrical screw part 10 from the lower end side thereof while maintaining the state in which the lipstick 1 and the case 3 are attached. The spiral component 10 has 1 spiral groove 10a repeating in the axial direction on the inner peripheral surface of the cylindrical member. The screw member 10 is disposed in a bottomed cylindrical bottle holder member 11 so as to be rotatable relative to the bottle holder member 11 about a cylindrical axis.

In the present specification, the term "up and down" means that the tip side of the stick-shaped lipstick 1, in other words, the forward side of the lipstick 1 in the screwing-out direction is defined as "up", and the backward side of the lipstick 1 opposite thereto in the screwing-out direction is defined as "down". In the present embodiment, the base end portion of the lipstick 1 is directly held by the cosmetic holder 2, but the base end portion of the lipstick 1 may be indirectly held by the cosmetic holder 2 via some member.

Fig. 4 is a diagram showing the screw member 10, the bottle holder member 11, and the mechanism around them in detail in an exploded state. The above mechanism will be described in detail below with reference to fig. 4. The inner cylinder 14 is also disposed inside the screw member 10 disposed in the bottle holder member 11. The intermediate tube 14 is formed of a substantially cylindrical member, and has 2 slits 14a formed in the circumferential wall thereof at angular intervals of 180 ° (degrees) apart from each other, the slits extending in a direction parallel to the tube axis in most parts. Each slit 14a is formed so as to be continuous with a short bent portion 14b bent from the slit upper end to the circumferential direction of the inner tube 14. Further, a lower end portion of the inner tube 14 is provided with a joining notch 14 c. A joint portion formed on the peripheral wall of the bottle holder member 11 outside the figure is joined to the joining notch 14 c. Thereby, the inner tube 14 and the bottle holder 11 are integrally rotatable relative to the screw 10.

Inside the inner tube 14, a vertically movable component 20 having a detailed shape shown in fig. 5 is housed. The upper and lower movable components 20 have 2 protrusions 23 facing the outer circumferential side, and are combined with the middle tube 14 by passing the protrusions 23 through the slits 14a, respectively. Thereby, the upper and lower movable parts 20 can be relatively moved in the cylinder axial direction with respect to the middle cylinder 14, that is, along the linear portion of the slit 14 a. The tip of the projection 23 protruding from the slit 14a is housed in the spiral groove 10a of the spiral component 10. The spiral component 10 and the inner tube 14 are formed of, for example, ABS resin, PS (polyethylene) resin, or the like.

The upper and lower movable components 20 will be described in detail with reference to fig. 5. In fig. 5, (a), (b), and (c) show the three-dimensional shape, the plan shape, and the side view shape of the upper and lower movable components 20, respectively. As shown in the drawing, the upper and lower movable parts 20 are integrally formed with 2 peripheral wall portions 21 each having a shape forming a part of a substantially cylindrical shape, 2 base portions 22 similarly formed into a shape forming a part of a substantially cylindrical shape and connecting the peripheral wall portions 21, and a convex portion 23 protruding outward from each outer peripheral surface of the 2 peripheral wall portions 21. The peripheral wall portion 21 has the above-described shape, and therefore has a through hole extending in the vertical direction (the vertical direction in fig. a, and the direction perpendicular to the paper surface in fig. b) in the central portion thereof. Further, a gap is formed between the 2 peripheral wall portions 21. The upper and lower movable components 20 are formed using PHBH which is preferable from the viewpoint of environmental protection as described above, for example.

As described above, the upper and lower movable parts 20 are disposed in the middle tube 14 and move relative to the middle tube 14 in the tube axial direction. At this time, if the upper and lower movable parts 20 are loosened (shaken), that is, moved in the radial direction of the inner tube 14, the feeling of use is impaired. Therefore, the base portion 22 of the upper and lower movable components 20 that contact the inner peripheral surface of the inner tube 14 has a shape and a size that closely contact the inner peripheral surface.

Next, the cosmetic holding portion 2 to which the upper and lower movable members 20 are joined will be described in detail with reference to fig. 6 and 7. Fig. 6 shows a three-dimensional shape of the cosmetic holder 2 holding the lipstick 1. Fig. 7 (a) and (b) show the side surface shape of the cosmetic holding portion 2 and the side cross-sectional shape in the plane including the cylinder axis, respectively. As shown in these figures, the cosmetic holding portion 2 has a substantially cylindrical outer peripheral wall portion 2a that holds the lipstick 1 inside and is formed in an upper end portion, and a substantially cylindrical inner peripheral wall portion 2d that is concentrically disposed inside the outer peripheral wall portion 2a, and is formed in a double cylindrical shape as a whole. On the peripheral surface of the outer peripheral wall portion 2a, a lateral groove 2b extending in a direction parallel to one tangential direction of the outer peripheral wall portion 2a is formed. Further, a vertical groove 2c extending in the axial direction of the outer peripheral wall portion 2a is formed on the peripheral surface of the outer peripheral wall portion 2a below the lateral groove 2 b. The above-described sets of the lateral grooves 2b and the vertical grooves 2c are provided in 2 sets at angular intervals of 180 degrees from each other in the circumferential direction of the outer peripheral wall portion 2 a. On the other hand, 2 locking (play prevention) ribs 2e (see fig. 6) protruding outward from the inner peripheral wall 2d are formed on a part of the outer peripheral surface of the inner peripheral wall 2 d.

When the upper and lower movable elements 20 and the cosmetic holding portion 2 are joined, the 2 locking ribs 2e enter the gap between the peripheral wall portions 21 of the upper and lower movable elements 20, and the outer surfaces thereof are aligned with the outer peripheral surface of the base portion 22 (see fig. 5). Therefore, when the cosmetic holding portion 2 is relatively moved in the cylinder axial direction in the middle cylinder 14 together with the upper and lower movable parts 20, the looseness of the cosmetic holding portion 2 is also prevented.

Hereinafter, a structure for more reliably joining the cosmetic holding portion 2 and the upper and lower movable components 20 will be described. A notch C extending in the cylinder axial direction and opening to the outside, that is, downward of the outer peripheral wall portion 2a is formed in the outer peripheral wall portion 2a of the cosmetic holding portion 2 having a cylindrical shape. The notch C has a substantially L-shape extending upward from the opening portion and then extending in the circumferential direction of the outer peripheral wall portion 2 a. Therefore, a tongue-shaped pressing portion 2f extending along the portion extending in the circumferential direction is formed below the portion of the notch C. Since the cosmetic holding portion 2 is formed of the above-described resin or the like, the pressing portion 2f can be elastically deformed particularly at the distal end portion in the radial direction of the outer peripheral wall portion 2 a. The distal end surface 2g of the pressing portion 2f is formed into a substantially "く" shape, that is, a shape in which an upward portion and a downward portion from a substantially central portion in the vertical direction are inclined in opposite directions, and forms a notch narrowing portion which narrows the notch C in the middle.

Fig. 7 (c) schematically shows the positional relationship between the upper and lower movable members 20 and the cosmetic product holding portion 2 when they are joined. As shown in the drawing, in a state where the convex portion 23 of the upper and lower movable parts 20 enters the notch C, the movement of the convex portion 23 is prevented by the distal end surface 2g of the pressing portion 2f (more specifically, the upper inclined surface of the distal end surface 2g in the substantially "く" shape) and is more reliably performed. The above-described sets of the notch C and the pressing portion 2f are only 1 set in fig. 7 (a) and 6, but actually, 2 sets are provided at angular intervals of 180 degrees apart from each other in the circumferential direction of the outer peripheral wall portion 2a so as to correspond to 2 convex portions 23 of the vertical movable component 20.

Next, the housing 3 shown in fig. 1 to 3 will be described in detail. The case 3 is formed to cover the stick-shaped lipstick 1 protruding from the cosmetic holder 2 from the outside over the entire length. Here, the "covering from the outside" does not limit the lipstick 1 to be sealed inside. That is, the term "cover from the outside" means that the case 3 is covered in a shape sufficient to protect the lipstick 1 when the lipstick 1 as a so-called "refill" is stored in the refill housing box 4 and sold or the like as described above. Therefore, in the present embodiment, when the case 3 is described assuming a box-shaped member constituting a substantially rectangular body, the case is: the front surface (the side surface on the lipstick 1 side in fig. 3 (c)) and the lower surface of such a member are open, and the back surface has a shape in which only a portion extending in the vertical direction remains in the center portion, and the portion continuing to the back surface is largely open and only the upper surface remains in the entire surface.

As shown in fig. 3c, the housing 3 has a lateral rib 3a and a vertical rib 3b (only one rib on one side is shown in the drawing) formed on the inner surfaces of the left and right side surfaces, and a vertical rib 3c formed on the inner surface of the rear surface. As shown in fig. 3 (a) and (b), the case 3 is attached to the cosmetic holding portion 2 in a covering manner. In this covering adhesion state, the 2 lateral ribs 3a of the case 3 are engaged with the lateral grooves 2b of the cosmetic holding portion 2, the 2 vertical ribs 3b are engaged with the vertical grooves 2c of the cosmetic holding portion 2, and the vertical ribs 3c abut on the surface of the outer peripheral wall portion 2a (see fig. 7) of the cosmetic holding portion 2.

The stick-shaped cosmetic container according to the present embodiment is composed of the cosmetic holding portion 2, the case 3, the screw member 10, the inner tube 14, the bottle holder member 11, and the vertically movable member 20, which are elements other than the lipstick 1, the refill housing case 4, and the container lid 13, among the elements illustrated in fig. 1 to 7 described above. The operation of the stick-shaped cosmetic container according to the present embodiment will be described below. Fig. 3 (a), (b), and (c) show in sequence a state in which the lipstick 1 as a refill is disposed in a stick-shaped cosmetic container and is ready for use. First, as shown in fig. 3 (a), the cosmetic holder 2 taken out from the refill housing case 4 (see fig. 1 and 2) is joined and integrated with the vertically movable component 20 in the screw component 10 from the lower end side thereof while maintaining the state in which the lipstick 1 and the case 3 are attached. The joining and integration of the cosmetic holding portion 2 and the upper and lower movable members 20 will be described in detail later. Fig. 3 (b) shows the integrated state.

As shown in fig. 3 (a) and (b), when the case 3 is in a state of being attached to the cosmetic holding portion 2, the vertical rib 3c of the case 3 abuts against the outer peripheral wall portion 2a of the cosmetic holding portion 2 as described above, thereby defining the position of the case 3 in the front-rear direction (the direction in which the front surface and the rear surface face each other). Further, the lateral rib 3a of the case 3 is engaged with the lateral groove 2b of the cosmetic holding portion 2, so that the movement of the case 3 in the vertical and horizontal directions is suppressed. Further, the longitudinal ribs 3b of the case 3 are engaged with the longitudinal grooves 2c of the cosmetic holding portion 2, whereby the movement of the case 3 in the front-rear direction is suppressed. As described above, the lateral ribs 3a, the vertical ribs 3b, and the vertical ribs 3c of the case 3 function as joint portions that suppress movement of the case 3 in the longitudinal direction and the thickness direction of the lipstick 1.

Here, when the case 3 is formed of the aforementioned PHBH, ABS resin, or the like, the case 3 can be elastically deformed. Therefore, the lateral rib 3a of the case 3 and the lateral groove 2b of the cosmetic holder 2 are joined in a state where the lateral rib 3a is pressed against the lateral groove 2 b. Similarly, the vertical rib 3b of the case 3 is joined to the vertical groove 2c of the cosmetic holding portion 2 in a state where the vertical rib 3b is pressed against the vertical groove 2 c. Thus, these engagements can be performed reliably. In order to ensure this joining, the cosmetic holder 2 may be formed of an elastically deformable material such as an elastomer and the case 3 may be formed of a material that is less likely to be elastically deformed, in contrast to the above.

As described above, the case 3 can be reliably covered and attached to the cosmetic holding portion 2 while suppressing all movements in the front-back and vertical and horizontal directions (movements in the longitudinal direction and thickness direction of the lipstick 1). Therefore, when the lipstick 1 held by the cosmetic holder 2 is protected by the case 3 and stored in the refill housing case 4, the case 3 is not easily detached from the cosmetic holder 2 and the effect of protecting the lipstick 1 is not impaired.

Next, as shown in fig. 3 (c), the case 3 is removed from the cosmetic holder 2 by moving the case 3 in the back direction. At this time, when the case 3 is moved with a certain large force, the case 3 is elastically deformed, and the engagement between the vertical rib 3b of the case 3 and the vertical groove 2c of the cosmetic retaining portion 2 is released. As shown in fig. 3 (c), it is preferable to provide: a container lid 13 for covering the lipstick 1 protruding from the screw member 10 in a state where the case 3 is detached from the cosmetic holder 2. The container lid 13 is detachably attached to the screw member 10 and the bottle holder member 11, for example, in a covering manner. Further, together with the container lid 13, there may be provided: a container body having an opening at the upper end thereof and accommodating the screw member 10 and the bottle holder member 11.

Next, the joining and integration of the cosmetic holding portion 2 and the upper and lower movable components 20 and the release of the joining will be described. For ease of explanation, first, the state in which the lipstick 1 is joined and integrated, that is, the usable state will be explained. In this state, the inner peripheral wall portion 2d of the cosmetic holding portion 2 is housed in the through hole provided in the central portion of the peripheral wall portion 21 of the upper and lower movable parts 20 shown in fig. 4 and 5 (see fig. 7). The outer peripheral wall portion 2a of the cosmetic holding portion 2, particularly the pressing portion 2f, which is a part thereof, elastically grips the peripheral wall portion 21 from the outer side of the periphery, and the inner peripheral wall portion 2d of the cosmetic holding portion 2 is in close contact with and fitted to the inner wall of the peripheral wall portion 21, which is the peripheral wall of the through hole, so that the cosmetic holding portion 2 and the upper and lower movable components 20 are joined and integrated. In this state, as described above with reference to fig. 7 (c), the distal end surface 2g of the pressing portion 2f prevents the projection 23 from moving, and therefore, the engagement between the cosmetic holding portion 2 and the upper and lower movable components 20 is not easily released.

In the above state, the convex portion 23 of the upper and lower movable parts 20 passes through the slit 14a of the inner tube 14, and the tip end portion of the convex portion 23 is accommodated in the spiral groove 10a of the spiral part 10. Therefore, when the inner tube 14 and the bottle holder 11 are rotated relative to the screw 10, the vertically movable member 20 moves vertically along the slit 14a of the inner tube 14. When the upper and lower movable members 20 move in this manner, the cosmetic holder 2 joined thereto and the lipstick 1 held by the cosmetic holder 2 move in the vertical direction, and therefore the lipstick 1 can be advanced and retracted from the screw member 10. Therefore, the lipstick 1 protruding from the screw member 10 can be used for makeup. As described above, in the present embodiment, the middle cylinder 14, the screw member 10, and the bottle holder member 11 constitute a screwing-out mechanism for moving the vertically movable member 20 relative to the middle cylinder 14 in the cylinder axial direction.

When the vertical movable element 20 is moved upward along the slit 14a of the middle cylinder 14 by continuing the relative rotation of the middle cylinder 14 and the bottle holder element 11 with respect to the screw element 10 as described above, the convex portion 23 of the vertical movable element 20 reaches the upper end of the slit 14a of the middle cylinder 14, and is then guided by the spiral groove 10a and is drawn into the curved portion 14 b. In this state, the upper and lower movable components 20 cannot move further upward, and therefore the position of the upper and lower movable components 20 in this state is referred to as "top dead center". When the upper and lower movable elements 20 reach the top dead center, as shown in fig. 8, the pressing portion 2f of the cosmetic holding portion 2 engaged with the upper and lower movable elements 20 becomes such that the tip end portion thereof is aligned with the slit 14a of the middle tube 14.

When the front end of the pressing portion 2f is not aligned with the slit 14a of the middle tube 14, the pressing portion 2f is tightly pressed from the outer circumferential side by the inner circumferential surface of the middle tube 14. Therefore, in this case, the distal end portion of the pressing portion 2f cannot easily move in the radial direction of the outer peripheral wall portion 2a of the cosmetic holding portion 2. That is, the engagement between the upper and lower movable parts 20 and the cosmetic holding portion 2 is difficult to release. This state can be obtained when the upper and lower movable parts 20 are at the upper and lower positions other than the top dead center, and this state is schematically shown in fig. 9.

On the other hand, when the tip end of the pressing portion 2f is aligned with the slit 14a of the inner tube 14, the tip end of the pressing portion 2f can elastically deform radially outward of the outer peripheral wall portion 2a because it escapes into the slit 14 a. Therefore, when the cosmetic holder 2 or the lipstick 1 held by the cosmetic holder 2 is moved upward with respect to the upper and lower movable component 20 (i.e., with respect to the middle tube 14) with a certain large force in a state where the upper and lower movable component 20 is positioned at the top dead center, the distal end portion of the pressing portion 2f passes over the convex portion 23 upward while being elastically deformed, and the convex portion 23 is separated from the notch C of the outer peripheral wall portion 2a of the cosmetic holder 2 toward the notch opening side. Thus, the engagement of the upper and lower movable parts 20 with the cosmetic holding portion 2 is released.

Therefore, when the upper and lower movable members 20 and the cosmetic holding portion 2 are disengaged after the lipstick 1 held by the cosmetic holding portion 2 is used up, for example, as described above, and then the other cosmetic holding portion 2 holding a new lipstick 1 as a refill is pushed in from above toward the upper and lower movable members 20, the other cosmetic holding portion 2 is newly engaged with and integrated with the upper and lower movable members 20. Therefore, the lipstick 1 held by the other cosmetic holding part 2 can be newly used. When the separate cosmetic product holding portion 2 is pushed in from above toward the vertically movable component 20 as described above, when the vertically movable component 20 is brought into a state of top dead center, the distal end portion of the pressing portion 2f passes downward over the convex portion 23 while being elastically deformed, and the convex portion 23 enters the notch C and is stopped from moving by the distal end surface 2g of the pressing portion 2f, that is, the state shown in fig. 7 (C).

The engagement between the upper and lower movable components 20 and the cosmetic product holding portion 2 can be released and is difficult to release, and it is assumed that the engagement is released by a normal force, and even if the engagement is released by a particularly large force such as breaking a part of the container, for example, the engagement is not considered to be releasable. In general, even when the user moves the lipstick 1 upward to release the engagement between the movable upper and lower components 20 and the cosmetic product holding portion 2 in a state where the movable upper and lower components 20 are not at the top dead center, the user does not feel that the engagement is released, and thus can recognize that the engagement release is an erroneous operation in this state. In this regard, it is not necessary for a user who is accustomed to using the stick type cosmetic container or a user who has a sufficient understanding of the instruction manual for using the stick type cosmetic container, and this can be said to be true for most people who are not such a user.

As described above in detail, in the stick-type cosmetic container according to the present embodiment, since the engagement between the upper and lower movable elements 20 and the cosmetic holder 2 can be released when the upper and lower movable elements 20 are moved to the position near the top dead center with respect to the middle tube 14, and the engagement is difficult to release when the upper and lower movable elements 20 are at the other upper and lower positions, the cosmetic holder 2 can be removed for replacement only by a simple manual operation after moving the upper and lower movable elements 20 to the position near the top dead center, that is, by an operation of pulling out the cosmetic holder 2 from the upper and lower movable elements 20. In addition, in the stick-shaped cosmetic container according to the present embodiment, since the cosmetic holder 2 is configured as described above, the state in which the upper and lower movable parts 20 are joined and integrated with the cosmetic holder 2 can be reliably and stably maintained only by moving the upper and lower movable parts 20 to a position other than the vicinity of the top dead center.

In the above-described embodiment, the upper and lower movable parts 20 are provided with 2

protrusions

23, and 2 slits 14a are formed in the middle tube 14 in correspondence thereto, but 1 or 3 or more protrusions 23 may be provided, and the same number of slits 14a of the middle tube 14 as the number of protrusions 23 are formed in correspondence thereto. This point is also the same as in embodiment 2 described later.

Here, the configuration of the case 3 shown in fig. 1 to 3 other than the above-described lateral rib 3a,

vertical ribs

3b, and 3c will be described in detail. Fig. 10 is a diagram showing the shape of the housing 3 in more detail. As shown here, the housing 3 is formed three-dimensionally by: approximately

The left and right side plates 3d are arranged at a distance from each other, and the front ends of the upper protruding portions are connected to each other by an upper horizontal member 3e, the front ends of the lower protruding portions are connected to each other by a lower horizontal member 3f, and the central portions of the upper horizontal member 3e and the lower horizontal member 3f are connected to each other by a vertical member 3 g. The upper portion of the 2 side plates 3d is closed by a top plate 3h in order to protect the lipstick 1 (see fig. 1 and 2) held by the cosmetic holding portion 2. On the other hand, the lower portions of the side plates 3d are opened to pass through the cosmetic holding portion 2. The lateral rib 3a and the vertical rib 3b are formed integrally with the lower protruding portion of the side plate 3d on the inner side thereof, and the vertical rib 3c is formed integrally with the lower lateral member 3f on the inner side thereof.

The shape of the side plate 3d is not limited to the shape shown in fig. 10, and may be other shapes. For example, a case 33 as shown in fig. 11 can be applied

A vertical part and a horizontal part which are connected with each other via a side plate 3d having an arc-shaped part. In fig. 10, the same elements as those already described are denoted by the same reference numerals, and redundant description thereof (the same applies hereinafter) is omitted unless otherwise particularly required.

The top plate 3h is not limited to the rectangular shape shown in fig. 10 and 11, and may have other shapes. For example, a baseball home-base pentagonal roof 3h or the like may be applied as in the case 43 shown in fig. 12. In this example, the upper cross member 3e has a shape in which one side is continuous at an angle to the other side with the center position therebetween, corresponding to the shape of the top plate 3 h. For example, as in the case 53 shown in fig. 13, a top plate 3h or the like in which one side of a rectangle is replaced with an arc-shaped portion may be applied. In this example, the upper cross member 3e has a curved shape corresponding to the shape of the top plate 3 h.

Next, a stick-shaped cosmetic container 60 according to embodiment 2 of the present invention will be described with reference to fig. 14 to 19. The stick-type cosmetic container 60 is formed in an elongated shape as a whole, and as shown in fig. 14, includes a cosmetic holding portion 61 that holds lipstick 1, which is an example of stick-type cosmetics, a vertically movable member 62 in a substantially elongated circular tube shape, a substantially cylindrical middle tube 63 that accommodates the vertically movable member 62, the cosmetic holding portion 61, and lipstick 1 in a coaxial state, and a screw member 64 that accommodates a lower portion of the middle tube 63 in a coaxial state. The cosmetic holder 61 and the vertically movable component 62 are formed of the biodegradable polymer PHBH, ABS resin, or the like as described above, as an example. The intermediate cylinder 63 and the spiral part 64 are also formed of, for example, the ABS resin, the PS resin, or the like described above.

Fig. 15 is a diagram showing the above-described components 61 to 64 in detail in an exploded state. As shown in the drawing, the cosmetic holder 61 holds one end portion, i.e., a lower end portion in the drawing, of the lipstick 1 at an upper portion. The vertical movable component 62 is joined to the cosmetic holding portion 61 and integrated with the cosmetic holding portion 61. Here, a structure for achieving the above-described joining will be described with reference to fig. 16. The cosmetic holder 61 is composed of a ring-shaped main body portion 61a holding the lipstick 1 and an engaging portion 61d having a convex portion 61 c. The engaging portion 61d extends downward from the main body portion 61 a. The convex portion 61c is formed in a small cylindrical shape, for example, and is formed in a state of facing radially outward on the outer peripheral surface of the joining portion 61 d. The convex portions 61c are provided on the outer peripheral surface of the joining portion 61d at angular intervals of, for example, 180 ° (degrees) by 2.

On the other hand, the upper part of the vertically movable component 62 is formed in a cylindrical shape, and 2 pressing parts 62a are formed in the cylindrical portion. The cylindrical portion and the pressing portion 62a are substantially the same as the outer peripheral wall portion 2a and the pressing portion 2f (see fig. 7) in embodiment 1. In addition, in the cylindrical portion, similarly, 2 notches 62b similar to the notch C (see fig. 7) in embodiment 1 are formed, and 2 circumferential notches 62C for elastically deforming the pressing portion 62a in the radial direction are formed. As described above, in embodiment 2, it can be said that, contrary to embodiment 1, the cosmetic holding portion 61 is provided with the convex portion 61c for engagement, and the upper and lower movable members 62 are formed with the notches 62b for engagement.

When the cosmetic holding portion 61 is pressed downward with a certain large force from the state shown in fig. 16, the engaging portion 61d is closely accommodated in the cylindrical portion of the vertically movable part 62. At this time, the 2 convex portions 61c enter the notches 62b, respectively, pass over the peak-shaped distal end portion of the pressing portion 62a while elastically deforming the pressing portion 62a radially outward, and are held between the pressing portion 62a and the circumferential notches 62 c. With this, the vertically movable component 62 is engaged with the cosmetic holding portion 61.

When the cosmetic holder 61 is pulled upward from the vertical movable component 62 with a certain large force from the above-described joined state, the joining is released. However, the engagement release is obtained only when the pressing portion 62a is elastically deformable radially outward, and the engagement release is difficult when the pressing portion 62a is not elastically deformable radially outward.

Returning to fig. 15, the configuration of the components 61 to 64 other than the above will be described. The upper and lower movable parts 62 have a convex portion 62d on the outer peripheral surface at a portion near the lower end. The projections 62d are provided at angular intervals of 180 ° (degrees), for example, in an amount of 2. The substantially cylindrical intermediate tube 63 has a screwing-out groove 63a extending from a lower end surface in the longitudinal direction of the intermediate tube 63. The spin-out grooves 63a extend across a length of, for example, half of the entire length of the middle tube 63, and are provided at angular intervals of, for example, 180 ° (degrees) by 2. The middle tube 63 has a convex portion 63b on the outer peripheral surface at a portion near the lower end. The projections 63b are provided at angular intervals of 180 ° (degrees), for example, in an amount of 2. On the other hand, the spiral component 64 is formed in a substantially bottomed cylindrical shape, and a spiral groove 64a is provided on the inner surface of the peripheral wall thereof.

The components 61 to 64 are combined as described below to obtain a stick-shaped cosmetic container 60. First, as shown in fig. 17, the cosmetic holding portion 61 and the upper and lower movable members 62 joined to each other as described above are inserted into the middle tube 63 in a state where the protrusion 62d is accommodated in the screwing-out groove 63 a. Here, although the cosmetic holder 61 holding the lipstick 1 is shown in a state of being engaged with the upper and lower movable elements 62, only the upper and lower movable elements 62 may be inserted into the middle tube 63 in a state where the engagement is not performed. In particular, when the lipstick 1 as the "refill" is provided in the stick-shaped cosmetic container 60 after assembly, such a state is usually achieved.

Next, as shown in fig. 18, the inner tube 63 is housed in the screw member 64. At this time, the projection 62d that bulges out from the screwing-out groove 63a to the outside in the radial direction of the inner tube 63 is accommodated in the spiral groove 64 a. The projection 63b is accommodated in an annular recess (not shown) formed in the inner surface of the peripheral wall of the spiral part 64 near the bottom of the spiral part 64, for example, while elastically deforming the projection 63 b. Thus, the inner tube 63 can be combined with the screw member 64 so as to be relatively rotatable in the circumferential direction without coming off the screw member 64. In addition, in order to combine the inner tube 63 and the spiral part 64 so as to be relatively rotatable, other known structures may be applied. For example, an annular convex portion may be provided on the outer peripheral surface of the inner tube 63, and a pair of annular members may be provided inside the screw part 64 so as to sandwich the annular convex portion from above and below.

Fig. 14 shows the stick type cosmetic container 60 assembled as described above. In this stick type cosmetic container 60, when the user holds the middle tube 63 with one hand and rotates the screw part 64 in the circumferential direction with the other hand, for example, the protrusion 62d, that is, the up-down movable part 62 moves up and down along the unscrewing groove 63a of the middle tube 63. Since the direction of the vertical movement changes according to the rotational direction of the screw member 64, the lipstick 1 can be screwed out from the upper end of the middle tube 63 or can be accommodated in the middle tube 63. That is, in the present embodiment, the middle cylinder 63 and the spiral part 64 constitute a screwing-out mechanism for moving the vertically movable part 62 relative to the middle cylinder 63 in the cylinder axial direction.

Fig. 14 and 18 show the state of the lipstick 1 used as described above. In this state, the periphery of the pressing portion 62a (see fig. 16) of the upper and lower movable members 62 is surrounded by the intermediate tube 63, and cannot be elastically deformed in the radial direction of the upper and lower movable members 62. Therefore, in this state, as described above, it is difficult to release the engagement between the cosmetic holding portion 61 and the vertically movable component 62. This enables the lipstick 1 held by the cosmetic holder 61 to be used in a stable state.

When the lipstick 1 is repeatedly used as described above, the length of the lipstick 1 becomes gradually shorter, and accordingly, it is necessary to perform the unscrewing operation so that the relative height position of the upper and lower movable parts 62 with respect to the middle tube 63 becomes higher. However, when the upper and lower movable components 62 move relatively upward with respect to the inner tube 63 until the convex portion 62d comes into contact with the upper end of the unscrewing groove 63a, the upper and lower movable components 62 cannot move relatively further upward with respect to the inner tube 63. That is, when the projection 62d contacts the upper end of the unwinding groove 63a, the upper and lower movable parts 62 are at the top dead center described above.

Fig. 19 shows a state in which the upper and lower movable members 20 have reached the top dead center. In this state, the lipstick 1 can be used up. In this state, the convex portion 61c of the cosmetic holder 61 and the notch 62b of the upper and lower movable elements 62 are exposed above the upper end of the middle tube 63. Therefore, as is apparent from fig. 16, the pressing portion 62a of the upper and lower movable parts 62 is also exposed above the upper end of the intermediate tube 63. In this state, the pressing portion 62a is elastically deformable in the radial direction of the vertically movable component 62. Therefore, when the cosmetic holding portion 61 is pulled upward with a certain large force so as to be separated from the upper and lower movable members 62, the engagement between the two is released. Next, when a new cosmetic holding portion 61 holding the lipstick 1 as a refill is pressed from above with respect to the vertically movable member 62, the pressing portion 62a is also elastically deformed at this time, and the new cosmetic holding portion 61 is engaged with the vertically movable member 62. Therefore, thereafter, a new lipstick 1 as a refill held by the cosmetic holding portion 61 can be used.

Next, a stick-shaped cosmetic container 70 according to embodiment 3 of the present invention will be described with reference to fig. 20 to 23. In this stick type cosmetic container 70, basically, a screwing mechanism for relatively moving the upper and lower movable members in the axial direction of the cylinder with respect to the middle cylinder is different from the stick type cosmetic container 60 according to embodiment 2 described above. Hereinafter, the screwing mechanism will be mainly described in detail.

Fig. 20 (1) and (2) are vertical sectional views showing a stick type cosmetic container 70 in a state different from each other by partially cutting the stick type cosmetic container, and fig. 21 is a perspective view showing the overall shape of the stick type cosmetic container 70. As shown in fig. 21, the stick type cosmetic container 70 includes a middle tube 71 for screwing out lipstick 1 as an example of stick type cosmetic, and a bottle holder 72 for accommodating a lower portion of the middle tube 71. Fig. 20 shows elements disposed inside the inner tube 71 and the bottle holder part 72, with a surface including the tube axis of the inner tube 71 being cut off. As shown in fig. 20, the middle tube 71 accommodates a cosmetic holding portion 73 that holds the lipstick 1 and a vertically movable component 74 that is engageable with the cosmetic holding portion 73. The cosmetic holding portion 73 and the vertically movable member 74 joined to each other are provided so as to be movable in the tube axial direction within the inner tube 71. The upper portion of the screw 75 is connected to the lower portion of the upper and lower movable members 74. In the present embodiment, the cosmetic holding portion 73 and the vertically movable component 74 are also formed of the biodegradable polymer PHBH, ABS resin, or the like as described above, as an example. The inner tube 71 and the bottle holder part 72 are also made of, for example, the ABS resin or the PS resin described above.

Here, the cosmetic holding portion 73, the vertically movable member 74, and the screw 75 will be described in detail with reference to fig. 22. In the drawings, (1) and (2) are a side view and a perspective view respectively showing the cosmetic holding portion 73 and the upper and lower movable members 74 in a state before engagement. The cosmetic holding portion 73 has a cylindrical joining portion 73a extending downward from a portion holding the lipstick 1. The joint portion 73a includes 1 cylindrical

convex portion

73b and 1 linear convex portion 73c arranged at a predetermined angular interval from the convex portion 73b on the outer circumferential surface in the vicinity of the upper end. The columnar convex portion 73b extends outward in the diameter direction of the joint portion 73a, and the linear convex portion 73c extends in the longitudinal direction of the joint portion 73 a.

On the other hand, the vertically movable part 74 is a substantially bottomed cylindrical member capable of accommodating the joining portion 73a therein, and a pressing portion 74a, a notch 74b, a circumferential notch 74c, and a longitudinal notch 74d are formed in an upper portion thereof. The pressing portions 74a, the notches 74b, and the circumferential notches 74c are substantially the same as the pressing portions 62a, the notches 62b, and the circumferential notches 62c shown in fig. 16, respectively. Therefore, the cosmetic holding portion 73 can be engaged with the vertical movable component 74 by being pressed against the vertical movable component 74 in a state where the cylindrical convex portion 73b is inserted into the cutout 74b from above and the linear convex portion 73c is inserted into the vertical cutout 74d from above. In this case, the cosmetic holder 73 is reliably prevented from loosening in the circumferential direction with respect to the vertically movable component 74 by the linear protrusions 73c being received in the longitudinal notches 74 d. On the other hand, the upper portion of the screw 75 is connected to the lower portion of the upper and lower movable members 74 so as to be rotatable relative to the upper and lower movable members 74 in the circumferential direction and immovable relative to each other in the axial direction.

The explanation is continued with reference to fig. 20. The above-described upper and lower movable components 74 are disposed in the middle tube 71. The middle tube 71 and the vertically movable element 74 are combined so as to be relatively movable in the axial direction of the tube and not relatively rotatable in the circumferential direction, for example, by engaging a longitudinal ridge formed on one side with a longitudinal groove extending in the axial direction of the tube formed on the other side. Further, in a lower portion of the inner tube 71, a female screw member 76 having a female screw 76a is disposed so as to be rotatable in the circumferential direction with respect to the inner tube 71. Further, a female screw holder 77 is fixed to the inner peripheral surface of the bottle holder 72. A female screw 78 and a female screw 79 are fixed to the female screw holder 77. These

female screw parts

78 and 79 also have

female screws

78a and 79a inside, respectively. The female screw part 78 is integrated with the female screw part 76. The screw 75 is threadedly engaged with the internal thread 76a of the internally threaded part 76, the internal thread 78a of the internally threaded part 78, and the internal thread 79a of the internally threaded part 79 in this order from above.

In the stick-type cosmetic container 70, when the user holds the inner tube 71 with one hand and rotates the bottle holder 72 in the circumferential direction with the other hand, for example, the bottle holder is conveyed by the female screw 79a, the female screw 78a, and the female screw 76a, and the screw 75 moves in the longitudinal direction thereof. Therefore, the cosmetic holding portion 73 connected to the vertically movable member 74 of the screw 75 and coupled to the vertically movable member 74 moves vertically within the inner tube 71. Since the direction of the vertical movement changes according to the rotational direction of the bottle holder member 72, the lipstick 1 can be screwed out from the upper end of the inner tube 71 or stored in the inner tube 71. That is, in the present embodiment, the

female screw parts

79, 78, and 76 and the screw 75 constitute a screwing-out mechanism for moving the upper and lower movable parts 74 relative to the middle tube 71 in the tube axial direction.

In fig. 20, the lower end position of the screw 75 that moves as described above is shown as L1, L2, and L3 for each movement position of the screw 75. As shown in fig. 1, in a state where all of the unused lipsticks 1 are stored in the inner tube 71, the lower end position of the screw 75 is L1 at the lowest position. On the other hand, as shown in (2) of the figure, in a state where the lipstick 1 is projected to some extent from the upper end of the middle tube 71, the lower end position of the screw 75 is at L2.

From this state, as the remaining length of the lipstick 1 becomes shorter, the upper and lower movable parts 74 need to be set at higher positions with respect to the middle tube 71 when the lipstick 1 is used. However, when the upper and lower movable elements 74 are raised to the lower end position of the screw 75 to the position shown by L3 in fig. 20, the upper and lower movable elements 74 cannot be set to a higher position. That is, the upper and lower movable parts 74 are at the aforementioned top dead centers at this time. In order to prevent the vertical movable part 74 from rising as described above, for example, the following structure may be adopted: the falling prevention rib provided at the lower end of the upper and lower movable parts 74 collides with a rib provided on the inner surface of the female screw part 79.

Fig. 23 shows a state in which the upper and lower movable elements 74 have reached the top dead center. In this state, the lipstick 1 can be used up. In this state, the convex portion 73b of the cosmetic holder 73 and the notch 74b of the upper and lower movable elements 74 are exposed above the upper end of the inner tube 71. In this state, as in embodiment 2, the pressing portion 74a is elastically deformable in the radial direction of the vertically movable component 74. Therefore, the cosmetic holder 73 can be pulled out from the upper and lower movable members 74 so as to release the engagement with the upper and lower movable members 74, and a new cosmetic holder 73 holding the lipstick 1 as a refill can be engaged with the upper and lower movable members 74, as in embodiment 2.

Next, a stick-shaped cosmetic container 80 according to embodiment 4 of the present invention will be described with reference to fig. 24 to 26. This stick type cosmetic container 80 basically has the same configuration as the stick type cosmetic container 60 of embodiment 2 described above, but is different in the configuration in which the cosmetic holding section holding the lipstick 1 is fixed to the container side. Therefore, in fig. 24 to 26, the same elements as those shown in fig. 14 to 19 are shown by being denoted by reference numerals used in these figures, and the description of these elements is omitted unless otherwise particularly required.

The stick-shaped cosmetic container 80 is constituted by, for example, a vertically movable member 62 having a substantially elongated circular tube shape, a substantially cylindrical middle tube 63 for accommodating the vertically movable member 62, the cosmetic holding portion 61, and the lipstick 1 therein in a coaxial state, and a screw member 64 for accommodating a lower portion of the middle tube 63 therein in a coaxial state. When the screw part 64 is rotated in the circumferential direction by the other hand while holding the middle tube 63, the vertically movable part 62 moves vertically in the middle tube 63. The configuration for achieving this is also the same as that in the stick-shaped cosmetic container 60 according to embodiment 2.

On the other hand, the cosmetic holder 81 is integrated with the lipstick 1 from the beginning, and is sold as the above-described refill together with a case (not shown) for storing them. The cosmetic holding portion 81 and the mechanism associated therewith will be described in detail below with reference to fig. 25 and 26. The cosmetic holder 81 holds lipstick 1 at the upper part. A pressing portion 81a, a notch 81b, and a circumferential notch 81c are provided at the lower portion of the cosmetic holding portion 81. These pressing portions 81a, notches 81b, and circumferential notches 81c are substantially the same as the pressing portions 62a, notches 62b, and circumferential notches 62c shown in fig. 16. The combination of the pressing portion 81a, the notch 81b, and the circumferential notch 81c is provided in 2 groups, but these groups are different from the configuration of fig. 16 and are arranged plane-symmetrically with respect to a plane passing through the intermediate positions thereof.

In addition, a guide portion 81d extending below the pressing portion 81a, the notch 81b, and the circumferential notch 81c is formed in the cosmetic holding portion 81 so as to pass through the portion where the pressing portion 81a, the notch 81b, and the circumferential notch 81c are provided. On the outer peripheral surface of the

guide portion

81d, 2 guide protrusions 81e are formed at angular intervals of 180 degrees from each other.

On the other hand, the vertically movable part 62 has 2 coupling portions 82 formed in a shape in which a part of a substantially cylindrical shape is cut out at the upper portion. Each coupling portion 82 has an outer surface provided with, for example, a small cylindrical projection 82a projecting radially outward. Therefore, when the cosmetic holding unit 81 is pushed into the coupling unit 82 after the 2 notches 81b are brought into a state of facing the convex portions 82a (the state of fig. 25), the convex portions 82a reach the circumferential notches 81c, and then, when the cosmetic holding unit 81 is rotated about its longitudinal axis, the cosmetic holding unit 81, that is, the lipstick 1 is coupled to the coupling unit 82 (the state of fig. 26). In addition, when the coupling is performed, the 2 guide convex portions 81e of the guide portion 81d are accommodated in the guide groove 82b between the 2 coupling portions 82. Thereby, the cosmetic holder 81 is coupled to the coupling portion 82 while maintaining a predetermined relative positional relationship. Then, in order to release the coupling, the cosmetic holding portion 81 may be rotated about its longitudinal axis so that the 2 notches 81b face the protrusions 82a, respectively, and then the cosmetic holding portion 81 may be pulled away from the coupling portion 82 with a certain strong force.

While the embodiment of the stick-shaped cosmetic container configured as the container for accommodating the stick-shaped lipstick 1 has been described above, the stick-shaped cosmetic container of the present invention may be configured as a container for accommodating stick-shaped cosmetics other than lipstick, for example, an eyeliner, eye shadow, and the like, and in such a case, the same effects as those described in the above embodiment are exhibited.

In the above-described embodiment, the lipstick 1 as a stick-type cosmetic is formed in a substantially cylindrical shape, but the shape of the stick-type cosmetic is not limited thereto. For example, the stick type cosmetic container of the present invention may be configured as a container for storing a polygonal column-shaped stick type cosmetic or the like. In the present embodiment, the lipstick 1 as the refill is held by the cosmetic holding portion 2, but the present invention is also applicable to a case where the same stick cosmetic is detachably held by the cosmetic holding portion 2, instead of the stick cosmetic as the refill, for example, for the reason that it is desired to store the stick cosmetic in a predetermined environment when not in use, or to select and use a plurality of different stick cosmetics.

In the above-described embodiment, the cosmetic holding portion is constituted by one component, but the cosmetic holding portion may be constituted by combining a plurality of components. The cosmetic holder is configured to hold the lipstick 1 in a cylindrical portion, but in particular, in the case where the cosmetic holder indirectly holds the stick-shaped cosmetic via a member, the cosmetic holder may be configured to hold the stick-shaped cosmetic in a portion having a shape other than a cylindrical shape.
