Rod-shaped object spinning container

Abstract

The object of the present invention is to provide an ejection-type stick-shaped object screw-out container that can reduce the number of discarded parts. The stick-shaped object screw-out container involved in one embodiment of the present invention comprises: a box portion having a stick-shaped cosmetic; and a push pin mechanism portion that moves the stick-shaped cosmetic forward and backward. The box portion has a movable body and an internal thread component, and the push pin mechanism portion has a connecting component, a push pin component, a spring component, a main barrel and a rotating component. When the push pin component is pressed, the pressed force is converted into a rotational force, causing the connecting component and the internal thread component to rotate relative to one direction, thereby moving the movable body and the stick-shaped cosmetic forward. When the rotating component rotates relative to the main barrel in the opposite direction, the connecting component and the internal thread component rotate relative to each other in the opposite direction, thereby moving the movable body and the stick-shaped cosmetic backward.

Description

Technical Field

[0001] The invention relates to an ejection type rod-shaped object screwing-out container for screwing out the rod-shaped object by ejection. Background Art

[0002] In the past, various containers have been known as rod-shaped object screw-out containers for screwing out rod-shaped objects by ejection. Japanese Patent Gazette No. 2020-103684 describes a screw-out container for screwing out rod-shaped contents held by a retaining tube. The screw-out container includes an outer tube, a spiral tube arranged inside the outer tube, a receiving tube inserted inside the spiral tube, and the retaining tube. A rotating part, a pin ejection part, a clamping ring, a force-applying part, a ring part, a lid, a pin ejection mechanism, and a locking mechanism are provided inside the outer tube.

[0003] In this screw-out container, when the lid is removed and the ejector pin is pushed upward (for ejection operation), the ejector pin pushes up the rotating member, and the spiral tube, the clamping ring, the retaining tube, and the rod-shaped contents move upward relative to the accommodating tube and the outer tube together with the rotating member. At this time, the rotating member rotates toward one side in the circumferential direction relative to the ejector pin and the outer tube. Thereafter, the rod-shaped contents protrude upward relative to the outer tube and become usable.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2020-103684 Summary of the invention

[0007] (Problems to be solved by the invention)

[0008] In the aforementioned screw-out container, the stick-shaped content is screwed out by the ejection operation of pushing the ejector member upward. However, after the stick-shaped content is used up, the entire screw-out container may be discarded. From the viewpoint of environmental protection, it is desirable to reduce the number of discarded parts, and the ejector-type stick-shaped object screw-out container is also required to reduce the number of discarded parts.

[0009] The object of the present invention is to provide a ejection type rod-shaped object screw-out container which can reduce the number of discarded parts.

[0010] (Measures taken to solve the problem)

[0011] The rod-like object screw-out container involved in the present invention comprises: a box portion having a rod-like object; and a pin ejection mechanism portion capable of loading and unloading the box portion and moving the rod-like object forward and backward. The box portion comprises: a movable body having a gripping portion for gripping the rod-like object and having an external thread on the outer periphery; and a cylindrical internal thread component having an internal thread screwed into the external thread. The pin ejection mechanism portion comprises: a connecting component connected to the box portion and capable of rotating synchronously with the internal thread component when connected to the box portion; a pin ejection component capable of pressing the rod-like object forward; a spring component for applying force to the connecting component and the pin ejection component backward; a main body tube for accommodating the connecting component and the spring component; and a rotating component for accommodating the pin ejection component on the rear side of the main body tube and capable of rotating relative to the main body tube. When the pin ejection component is pressed, the pressed force is converted into a rotational force, so that the connecting component and the internal thread component rotate relative to the movable body in one direction, thereby moving the movable body and the rod-like object forward. When the pressing force on the knock pin member is released and the rotating member rotates relative to the main body tube in a direction opposite to one direction, the connecting member and the internal thread member rotate relative to the movable body in the opposite direction, thereby retreating the movable body and the rod-shaped object.

[0012] The rod-shaped object screw-out container includes a box portion having the rod-shaped object and a pin ejection mechanism portion capable of loading and unloading the box portion. Therefore, after the rod-shaped object is used up, the box portion is removed from the pin ejection mechanism portion, and only the box portion can be discarded. Therefore, there is no need to discard the entire rod-shaped object screw-out container, and when the box portion is replaced, a new box portion can be installed in the existing pin ejection mechanism portion. Therefore, the number of discarded parts can be reduced. The pin ejection mechanism portion includes: a connecting part that can rotate synchronously with the internal thread part of the box portion; a pin ejection part that advances the rod-shaped object; and a rotating part that accommodates the pin ejection part. When the pin ejection part is pressed, the pressed force is converted into a rotational force, so that the connecting part and the internal thread part rotate relative to the moving body in one direction, thereby advancing the moving body and the rod-shaped object. Therefore, the rod-shaped object can be advanced by pressing the pin ejection part, thereby screwing out the rod-shaped object, and thus the usability of the rod-shaped object screw-out container can be improved. That is, the rod-like object can be twisted out of the container by holding the rod-like object with one hand and pressing the ejector pin with the other hand, so that the rod-like object can be twisted out of the container with high usability. In addition, when the pressing of the ejector pin is released and the rotating part rotates relative to the main tube in the direction opposite to the above-mentioned one direction, the connecting part and the internal thread part rotate relative to the moving body in the opposite direction, thereby causing the moving body and the rod-like object to move backward. Therefore, the rod-like object can be moved backward by the relative rotation of the rotating part relative to the main tube. As described above, in the rod-like object twisting out container, the rod-like object can be twisted out by ejection and the rod-like object can be screwed in by rotation of the rotating part.

[0013] The box part may have a cylindrical part, which can rotate synchronously with the internal thread part at the rear side of the internal thread part, and is used to connect the connecting part, and may be as follows, that is, a first rib is formed on the inner surface of the cylindrical part, and the first rib extends along the axial direction of the axis of the cylindrical part, and a second rib is formed on the outer surface of the connecting part, and the second rib is engaged with the first rib in the rotation direction. In this case, the internal thread part of the box part and the connecting part of the ejector mechanism part can be connected via the cylindrical part, and the internal thread part, the cylindrical part and the connecting part can be rotated synchronously.

[0014] The pin ejection mechanism may include a cylindrical ratchet component, and the ratchet component accommodates the connecting component inside the main body tube. A third rib may be formed on the outer surface of the connecting component, and the third rib extends along the axial direction along which the axis of the ratchet component extends. A fourth rib may be formed on the inner surface of the ratchet component, and the fourth rib engages with the third rib in the rotation direction when the connecting component and the internal thread component rotate relative to the moving body in opposite directions. At this time, the ratchet component can be rotated synchronously with the connecting component and the internal thread component in opposite directions.

In addition, in the accompanying drawings, in order to facilitate understanding, a part is sometimes simplified or exaggerated for description, and the dimensional ratios and the like are not limited to those described in the accompanying drawings.

[0034] In the present invention, a "rod-shaped object" refers to a rod-shaped object applied to a coated portion as an object of application. The "rod-shaped object" may be, for example, a rod-shaped cosmetic or a rod-shaped drawing piece. In the present embodiment, an example in which the rod-shaped object is a rod-shaped cosmetic is described. "Cosmetics" may be, for example, lipstick, lip liner, lip gloss, eyeliner, eyebrow pencil, beauty stick, or concealer. "Cosmetics" may be a rod-shaped object containing a soft material (for example, a semi-solid, soft solid, soft, jelly, mousse, or a paste containing these, etc.).

[0035] Figure 1 (a) is a side view of the stick-shaped object screw-out container 1 according to the embodiment. Figure 1 (b) Yes Figure 1 (a) AA line cross-sectional view. Figure 1 (a) and Figure 1 As shown in (b), the stick-shaped object screw-out container 1 is, for example, a stick-shaped cosmetic screw-out container that is screwed out (pushed out) the stick-shaped cosmetic M contained therein by a user's ejection operation. As an example, the stick-shaped cosmetic M is a volatile stick-shaped cosmetic.

[0036] The stick-shaped screw-out container 1 is in the shape of a round stick. The stick-shaped screw-out container 1 extends along the axial direction D, which is the direction in which the axis L of the stick-shaped screw-out container 1 extends. The stick-shaped screw-out container 1 includes a box 10 having a stick-shaped cosmetic M and a pin ejector mechanism 20 that can be attached and detached from the box 10. The box 10 can be removed from the pin ejector mechanism 20 after the stick-shaped cosmetic M is used up, for example. In addition, a new box 10 can be attached to the pin ejector mechanism 20.

[0037] In the present invention, the direction in which the box portion 10 is set and the direction in which the stick-shaped cosmetic M is screwed out when viewed from the ejector mechanism portion 20 are referred to as “front”, “front side” or “front”, and the direction in which the ejector mechanism portion 20 is set and the direction in which the stick-shaped cosmetic M is screwed in when viewed from the box portion 10 are referred to as “rear”, “rear side” or “rear” for explanation.

[0038] Figure 2 (a) is a side view showing the box portion 10. Figure 2 (b) is a side view showing the ejector mechanism 20. Figure 1 (b) Figure 2 (a) and Figure 2As shown in (b), the ejector mechanism 20 comprises: an ejector member 21 for rotating the stick-shaped cosmetic M; a rotating member 22 for accommodating a portion of the ejector member 21; and a main body tube 23 connected to the rotating member 22 so as to be relatively rotatable. The rotating member 22 and the main body tube 23 are cylindrical. The rotating member 22 is disposed at the rear side of the main body tube 23. The ejector member 21 protrudes rearward from the rotating member 22.

[0039] First, the box portion 10 involved in this embodiment is described. The box portion 10 has a cover 11 and a front tube 12 to which the cover 11 is mounted. Inside the box portion 10, there are provided: a moving body 14 that moves along the axial direction D and has an external thread 14b; a cylindrical internal thread component 15 that has an internal thread 15b that is screwed with the external thread 14b; and a cylindrical component 16 that is located at the rear side of the internal thread component 15.

[0040] The cover 11 is in the shape of a bottomed cylinder. The cover 11 has an annular convex portion 11b on the inner surface, and the front cylinder 12 has a convex portion 12b on the outer surface that engages with the annular convex portion 11b in the axial direction D. The front cylinder 12 protrudes backward from the cover 11 in a state where the convex portion 12b engages with the annular convex portion 11b of the cover 11 in the axial direction D. The front cylinder 12 has an external threaded portion 12c. The box portion 10 is mounted on the ejector mechanism portion 20 by screwing the external threaded portion 12c with the ejector mechanism portion 20. In addition, the structure for mounting the box portion 10 on the ejector mechanism portion 20 is not limited to the above-mentioned screwing. For example, instead of the above-mentioned screwing, a structure in which protrusions are provided on the inner surfaces of each of the box portion 10 and the ejector mechanism portion 20, and the protrusions of the box portion 10 are engaged with the protrusions of the ejector mechanism portion 20 can be used.

[0041] Figure 3 (a) is a side view showing the front tube 12. Figure 3 (b) Yes Figure 3 (a) BB line cross-sectional view. Figure 1 (b) Figure 3 (a) and Figure 3 As shown in (b), the front tube 12 has: a front tube portion 12A; a rear tube portion 12B, which is located at a position closer to the rear side than the front tube portion 12A; and a flange portion 12d, which is located between the front tube portion 12A and the rear tube portion 12B. The rear tube portion 12B is a cylindrical portion extending backward from the flange portion 12d. The rear tube portion 12B is cylindrical. The aforementioned external thread portion 12c that is screwed with the inner surface of the main tube 23 is formed on the outer periphery of the rear tube portion 12B. The external thread portion 12c is provided on the rear side of the flange portion 12d.

[0042] The flange portion 12d is provided between the lid 11 and the main body tube 23, and is exposed to the outside of the container 1 when the rod-like object is screwed out. The front side tube portion 12A has: a tapered surface 12g, which decreases in diameter toward the front end 12f of the front tube 12; an annular recess 12h, which is located at the rear side of the tapered surface 12g; an inclined surface 12j, which is located at the rear of the annular recess 12h; and a protrusion 12k, which extends from the flange portion 12d toward the inclined surface 12j.

[0043] The front end 12f of the front barrel 12 is formed with an opening 12m for exposing the stick-shaped cosmetic M. An internal space 12p of the front barrel 12 for accommodating the stick-shaped cosmetic M is formed behind the opening 12m. The outer diameter of the front barrel 12 in the tapered surface 12g increases from the front end 12f toward the rear.

[0044] The annular recess 12h is provided to hold the O-ring 13. The O-ring 13 enters the annular recess 12h, and the O-ring 13 entering the annular recess 12h is in close contact with the inner surface of the cover 11. Thus, airtightness is ensured on the front side (front end 12f side) of the O-ring 13 when the cover 11 is installed.

[0045] The convex portion 12b is formed between the annular recess 12h and the inclined surface 12j. The front tube 12 has, for example, a plurality of convex portions 12b arranged along the circumferential direction of the front tube 12. The plurality of convex portions 12b are respectively engaged with the annular convex portion 11b of the cover 11 in the axial direction D. The convex portion 12b is circular.

[0046] The outer diameter of the front tube 12 in the inclined surface 12j increases toward the rear. A protrusion 12k extending in the axial direction D is provided behind the inclined surface 12j. The front tube 12 has a plurality of protrusions 12k, and the plurality of protrusions 12k are arranged along the circumferential direction of the front tube 12. The protrusions 12k engage with the inner surface of the cover 11, and the cover 11 is mounted on the front tube 12 in a state where the end surface 11c forming the opening of the cover 11 is opposite to the flange portion 12d along the axial direction D.

[0047] The internal space 12p of the front cylinder 12 extends rearward from the opening 12m. The internal space 12p penetrates the front cylinder 12 in the axial direction D. The internal space 12p accommodates the moving body 14, the internal thread member 15, and the tubular member 16. The moving body 14, the internal thread member 15, and the tubular member 16 are arranged in this order.

[0048] The inner space 12p is provided with a protrusion 12q extending along the axial direction D. The front cylinder 12 has, for example, a plurality of protrusions 12q. The protrusions 12q are provided to stop the moving body 14 from rotating. That is, the protrusions 12q engage with the moving body 14 in the rotation direction (circumferential direction). Thus, the moving body 14 engages with the front cylinder 12 so as to be unable to rotate.

[0049] A first step portion 12s is provided behind the protrusion 12q in the internal space 12p, the diameter of which is expanded from the inner surface 12r on which the protrusion 12q is formed, and a second step portion 12t is provided behind the first step portion 12s. The first step portion 12s is located closer to the front side of the front tube 12 than the second step portion 12t. The inner diameter of the front tube 12 behind the first step portion 12s is larger than the inner diameter of the front tube 12 in front of the first step portion 12s, and the inner diameter of the front tube 12 behind the second step portion 12t is larger than the inner diameter of the front tube 12 in front of the second step portion 12t.

[0050] The inner space 12p is provided with an annular recess 12v and an annular protrusion 12w that engage with the tubular member 16 in the axial direction D. The annular recess 12v and the annular protrusion 12w are located at a position rearward of the second step portion 12t. The annular recess 12v is provided in front of the annular protrusion 12w. The tubular member 16 that passes over the annular protrusion 12w engages with the annular recess 12v, whereby the tubular member 16 engages with the front tube 12 in the axial direction D.

[0051] Figure 4 14 is a side view showing the moving body 14. Figure 1 (b) and Figure 4 As shown, the movable body 14 includes a holding portion 14A that holds the stick-shaped cosmetic M and a stick-shaped portion 14B that extends from the holding portion 14A in the axial direction D and has the external thread 14b formed on the outer periphery. The holding portion 14A is located in front of the stick-shaped portion 14B.

[0052] The holding portion 14A includes a cylindrical gripping portion 14c for gripping the stick-shaped cosmetic M, and an engaging portion 14d located radially outside the gripping portion 14c and engaging with the protrusion 12q of the front tube 12 in the rotational direction. The engaging portion 14d engages with the protrusion 12q in the rotational direction, so that the movable body 14 is non-rotatably engaged with the front tube 12.

[0053] The rod-shaped portion 14B extends rearward from the holding portion 14A. The rod-shaped portion 14B has an external thread 14b and a curved surface portion 14f located at the rear side of the external thread 14b. The curved surface portion 14f corresponds to a portion where the external thread 14b is not formed, and is provided, for example, at the rear end of the moving body 14. The external thread 14b is a portion that is screwed with the internal thread 15b of the internal thread member 15, and forms a screwing portion T with the internal thread 15b.

[0054] Figure 5 (a) is a side view showing the internal thread member 15. Figure 5 (b) Yes Figure 5 (a) CC line cross-sectional view. Figure 1 (b) Figure 5 (a) and Figure 5As shown in (b), the internal thread member 15 has a cylindrical shape extending in the axial direction D. The internal thread member 15 has a cylindrical portion 15A and a spring portion 15B located at the rear side of the cylindrical portion 15A.

[0055] The cylinder 15A has a small diameter portion 15c located at the front side and a large diameter portion 15d located at the rear side. A step 15f is formed between the small diameter portion 15c and the large diameter portion 15d. The internal thread member 15 has an internal thread 15b on the inner surface of the small diameter portion 15c. The interior of the internal thread member 15 is set as a storage space 15g for accommodating the rod-shaped portion 14B of the moving body 14.

[0056] The internal thread component 15 has a protrusion 15h protruding radially outward of the internal thread component 15 between the cylinder portion 15A and the spring portion 15B. The protrusion 15h engages with the inner surface of the tubular component 16 in the rotational direction. The tubular component 16 engages with the internal thread component 15 in a synchronously rotatable manner by the protrusion 15h engaging with the inner surface of the tubular component 16 in the rotational direction.

[0057] The spring portion 15B extends backward from the protruding portion 15h. The spring portion 15B includes a cylindrical portion 15j and a slit 15k formed in the cylindrical portion 15j. The slit 15k is formed in a spiral shape extending in the cylindrical portion 15j along the axial direction D. The spring portion 15B includes the slit 15k to mitigate the impact transmitted to the inside when an external force acts, such as when the stick-like object is screwed out of the container 1 and falls, thereby protecting the stick-like object from being screwed out of the container 1 and the stick-like cosmetic M.

[0058] like Figure 1 (b) Figure 6 (a) and Figure 6 As shown in (b), the tubular member 16 is provided at the rear side of the internal thread member 15. The tubular member 16 is cylindrical. The tubular member 16 has a flange portion 16b protruding radially outward of the tubular member 16 at the rear end of the tubular member 16. The rear end 12x of the front tube 12 abuts against the flange portion 16b.

[0059] The cylindrical member 16 has an annular recess 16c located in front of the flange 16b and an annular protrusion 16d located in front of the annular recess 16c. The O-ring 17 that is in close contact with the inner surface of the front cylinder 12 enters the annular recess 16c. The O-ring 17 that enters the annular recess 16c is in close contact with the inner surface of the front cylinder 12, thereby ensuring the airtightness of the front cylinder 12. The annular protrusion 16d passes over the annular protrusion 12w of the front cylinder 12 forward and engages with the annular recess 12v. The cylindrical member 16 engages with the front cylinder 12 in the axial direction D by the engagement of the annular protrusion 16d with the annular recess 12v.

[0060] The tubular member 16 has a first internal space 16f for the internal thread member 15 to enter, and a second internal space 16g for the connecting member 24 of the pin ejection mechanism 20 described later to enter. The second internal space 16g is located at a rearward position than the first internal space 16f. The tubular member 16 has a wall portion 16h that separates the first internal space 16f and the second internal space 16g.

[0061] The first internal space 16f has a recessed portion 16j into which the protruding portion 15h of the internal thread member 15 enters. The recessed portion 16j penetrates the tubular member 16 in the radial direction and extends along the axial direction D. The protruding portion 15h enters the recessed portion 16j extending along the axial direction D, whereby the internal thread member 15 is engaged with the tubular member 16 so as to be rotatable in sync.

[0062] The first rib 16k is formed in the second internal space 16g, and the connecting member 24 entering the second internal space 16g engages with the first rib 16k in the rotation direction. The first rib 16k extends along the axial direction D. The first rib 16k has: a first extension surface 16m extending along the axial direction D; a second extension surface 16p extending along the axial direction D and extending to a position behind the first extension surface 16m; and an inclined surface 16q extending from the rear end of the first extension surface 16m to the rear end of the second extension surface 16p. The inclined surface 16q is inclined relative to the axial direction D.

[0063] Next, the pin ejection mechanism 20 according to the present embodiment will be described. The pin ejection mechanism 20 includes a ratchet member 25 and a spring member 26 in addition to the pin ejection member 21, the rotating member 22, the main body tube 23, and the connecting member 24. The connecting member 24, the ratchet member 25, and the spring member 26 are accommodated in the main body tube 23.

[0064] like Figure 1 (b) Figure 7 (a) and Figure 7 As shown in (b), the main body tube 23 is cylindrical with a smooth outer surface. That is, the main body tube 23 has no concave and convex on the outer surface. The main body tube 23 has a front inner space 23b, a rear inner space 23c, and a wall 23d separating the front inner space 23b and the rear inner space 23c.

[0065] The main body tube 23 has an internal thread portion 23f formed in the front internal space 23b. The external thread portion 12c of the front tube 12 is screwed with the internal thread portion 23f. The front tube 12 is mounted on the main body tube 23 by screwing the external thread portion 12c with the internal thread portion 23f. By mounting the front tube 12 on the main body tube 23, the box portion 10 is mounted on the ejector mechanism portion 20.

[0066] The main body tube 23 has a plurality of inclined protrusions 23g arranged along the rotation direction of the main body tube 23 on the rear side of the wall portion 23d. The inclined protrusions 23g are the parts that engage with the ratchet member 25 in the rotation direction. An annular recess 23h is formed in the rear internal space 23c. The annular recess 23h is the part that engages with the ratchet member 25 in the axial direction D.

[0067] like Figure 1 (b) Figure 8 (a) and Figure 8 As shown in (b), the connecting member 24 is rod-shaped. The connecting member 24 moves relative to the main body tube 23 along the axial direction D. The connecting member 24 engages with the box portion 10 (cylindrical member 16) in the rotational direction by moving forward (advancing) relative to the main body tube 23, and moves away from the box portion 10 by moving backward (retreating) relative to the main body tube 23.

[0068] The connecting member 24 includes: a front portion 24A; a rear portion 24B; and an expanded diameter portion 24C, which is located between the front portion 24A and the rear portion 24B and has a flange portion 24m having an outer diameter larger than that of the front portion 24A and the rear portion 24B. The front portion 24A includes a first outer peripheral surface 24c extending rearward from a front end 24b of the connecting member 24 and a second outer peripheral surface 24f extending rearward from a step portion 24d located at the rear end of the first outer peripheral surface 24c. The rear portion 24B includes an outer peripheral surface 24q extending rearward from the flange portion 24m. For example, the outer diameter of the rear portion 24B is smaller than that of the front portion 24A.

[0069] The connecting member 24 has a second rib 24g that engages with the first rib 16k of the tubular member 16 in the rotational direction. The second rib 24g protrudes from the first outer peripheral surface 24c and extends along the axial direction D. The height of the second rib 24g relative to the first outer peripheral surface 24c is, for example, the same as the height of the second outer peripheral surface 24f relative to the first outer peripheral surface 24c. At this time, the second rib 24g is set to be on the same plane as the second outer peripheral surface 24f.

[0070] The second rib 24g includes: a third extension surface 24h extending along the axial direction D; a fourth extension surface 24j extending along the axial direction D and extending further forward than the third extension surface 24h; and an inclined surface 24k extending from the front end of the third extension surface 24h to the front end of the fourth extension surface 24j. The inclined surface 24k is inclined relative to the axial direction D. The connecting member 24 has a plurality of second ribs 24g, and the tubular member 16 has a plurality of first ribs 16k. The connecting member 24 can be synchronously rotatably engaged with the tubular member 16 by the plurality of second ribs 24g respectively entering between a pair of first ribs 16k arranged in the rotation direction.

[0071] The enlarged diameter portion 24C includes a flange portion 24m protruding from the front portion 24A to the radially outer side of the connection member 24, and a third rib 24p extending rearward from the flange portion 24m. The connection member 24 includes a plurality of third ribs 24p arranged along the rotation direction of the connection member 24. The third rib 24p protrudes from the outer peripheral surface 24q of the rear portion 24B to the radially outer side of the connection member 24.

[0072] The third rib 24p has: a fifth extension surface 24r extending rearward from the flange portion 24m; a sixth extension surface 24s extending rearward from the flange portion 24m and extending further rearward than the rear end of the fifth extension surface 24r; and an inclined surface 24t extending from the rear end of the fifth extension surface 24r to the rear end of the sixth extension surface 24s.

[0073] The direction of the inclined surface 24t of the third rib 24p is opposite to the direction of the inclined surface 24k of the second rib 24g. The advancing ejector member 21 abuts against the inclined surface 24t, and the ejector member 21 abuts against the inclined surface 24t, whereby the connecting member 24 rotates relative to the ejector member 21. The third rib 24p is engaged with the ratchet member 25 located radially outside the connecting member 24 so as to be rotatable in sync.

[0074] like Figure 1 (b) Fig. 9 (a) and Fig. 9 As shown in (b), the ratchet component 25 is cylindrical. The ratchet component 25 has a front side cylinder 25A and a rear side cylinder 25B, and a flange portion 25b is formed between the front side cylinder 25A and the rear side cylinder 25B. The main body cylinder 23 is opposite to the front side of the flange portion 25b, and the rotating component 22 is opposite to the rear side of the flange portion 25b. The surface of the flange portion 25b facing the radial outside is exposed to the outside of the rod-like object rotating out of the container 1. The rear side cylinder 25B has an annular convex portion 25t protruding radially outward. The rotating component 22 engages with the annular convex portion 25t in the axial direction D.

[0075] The front tube 25A has an inclined protrusion 25c at the front end of the ratchet member 25, a spring portion 25d behind the inclined protrusion 25c, and a ratchet portion 25f behind the spring portion 25d. The inclined protrusion 25c is a portion that engages with the inclined protrusion 23g of the main tube 23 in the rotation direction.

[0076] The spring portion 25d includes a cylindrical portion 25g and a slit 25h formed in the cylindrical portion 25g. The slit 25h includes a first slit portion 25j extending in the rotation direction of the ratchet member 25, a second slit portion 25k extending in the rotation direction of the ratchet member 25 at a position behind the first slit portion 25j, and an inclined slit portion 25m extending from the first slit portion 25j to the second slit portion 25k and extending obliquely with respect to the axial direction D. The spring portion 25d includes the slit 25h, so that the inclined protrusion 25c and the inclined protrusion 23g of the main body tube 23 can be rotated in a predetermined direction (for example, counterclockwise when viewed from the rear).

[0077] The ratchet portion 25f has a fourth rib 25p formed on the inner surface of the ratchet member 25. The ratchet member 25 has a plurality of fourth ribs 25p arranged along the rotation direction of the ratchet member 25. The fourth ribs 25p protrude from the inner surface of the ratchet member 25 toward the inside in the radial direction of the ratchet member 25.

[0078] The fourth rib 25p includes a seventh extension surface 25q extending in the axial direction D, an eighth extension surface 25r extending in the axial direction D and extending further forward than the front end of the seventh extension surface 25q, and an inclined surface 25s extending from the front end of the seventh extension surface 25q to the front end of the eighth extension surface 25r. The fourth rib 25p is engaged with the third rib 24p of the connecting member 24 so as to be rotatable in sync.

[0079] The fourth rib 25p includes a front rib 25w and a rear rib 25x. The front rib 25w and the rear rib 25x are the parts that the ejector member 21 engages with in the rotation direction (the ejector member 21 stops rotation). The later-described convex portion 21g of the ejector member 21 in the unpressed state engages with the front rib 25w in the rotation direction, and the later-described tapered portion 21d of the ejector member 21 in the pressed state engages with the rear rib 25x in the rotation direction. In this way, the ejector member 21 engages with the fourth rib 25p in the rotation direction.

[0080] The front side cylinder 25A has an annular convex portion 25v protruding radially outward from the ratchet member 25. The annular convex portion 25v is provided on the front side of the flange portion 25b. The annular concave portion 23h of the main body cylinder 23 engages with the annular convex portion 25v. The main body cylinder 23 engages with the ratchet member 25 in the axial direction D by the engagement of the annular concave portion 23h and the annular convex portion 25v.

[0081] like Figure 1 (b) Fig.10 (a) and Fig.10As shown in (b), the rotating member 22 is cylindrical with a smooth outer surface. The rotating member 22 accommodates the rear cylinder 25B of the ratchet member 25 and the ejector member 21. A front accommodating portion 22b and a rear accommodating portion 22c having an inner diameter smaller than that of the front accommodating portion 22b are provided inside the rotating member 22, the rear cylinder 25B is accommodated in the front accommodating portion 22b, and the ejector member 21 is accommodated in the rear accommodating portion 22c.

[0082] The front accommodation portion 22b is formed with an annular recess 22d recessed radially outward from the rotating member 22. The annular protrusion 25t of the ratchet member 25 engages with the annular recess 22d. The ratchet member 25 engages with the rotating member 22 in the axial direction D by the engagement of the annular protrusion 25t with the annular recess 22d.

[0083] The rear accommodating portion 22c is formed with a spiral recess 22f. The spiral recess 22f is a step recessed from the inner surface 22g extending from the rear end of the rotating member 22 toward the radially outer side of the rotating member 22, and is a portion extending forward from the spiral wall 22h. The rotating member 22 has, for example, two spiral walls 22h.

[0084] The spiral wall 22h defining the spiral recess 22f is formed in a spiral shape. The spiral wall 22h is a spiral wall portion located at the rear end of the spiral recess 22f. The spiral wall 22h is a portion opposed to the convex portion 21b described later of the ejector member 21. The convex portion 21b moves along the spiral wall 22h, so that the rotating member 22 moves in a spiral shape relative to the ejector member 21.

[0085] like Figure 1 (b) Fig.11 (a) and Fig.11 As shown in (b), the push pin member 21 is in the shape of a bottomed cylinder. The push pin member 21 can be pressed to unscrew the stick-shaped cosmetic M. The push pin member 21 can be pressed forward, and the stick-shaped cosmetic M is unscrewed by pressing the push pin member 21 forward. The push pin member 21 has: a small diameter portion 21c located at the front side; a tapered portion 21d gradually expanding in diameter from the rear end of the small diameter portion 21c; and a large diameter portion 21f extending backward from the tapered portion 21d. The push pin member 21 has a plurality of tapered portions 21d, and the plurality of tapered portions 21d are arranged along the rotation direction of the push pin member 21.

[0086] The lift pin member 21 has a convex portion 21g on the small diameter portion 21c. The lift pin member 21 has a plurality of convex portions 21g, and the plurality of convex portions 21g are arranged along the rotation direction of the lift pin member 21. The convex portions 21g are arranged on an imaginary straight line that passes through the tapered portion 21d and extends along the axial direction D. That is, the position of the convex portion 21g in the rotation direction of the lift pin member 21 is the same as the position of the tapered portion 21d in the rotation direction of the lift pin member 21.

[0087] The protrusion 21g is engaged with the front rib 25w of the fourth rib 25p of the ratchet member 25 in the rotation direction. The ejector member 21 has a slit 21j extending rearward from the front end 21h of the ejector member 21. The tapered portion 21d of the ejector member 21 is engaged with the rear rib 25x of the fourth rib 25p of the ratchet member 25 in the rotation direction. The ejector member 21 has, for example, two protrusions 21b. The protrusion 21b is cylindrical. The protrusion 21b moves in a spiral shape along the spiral wall 22h of the rotating member 22.

[0088] The ejector mechanism 20 includes a spring member 26 disposed between the wall portion 23d of the main tube 23 and the flange portion 24m of the connecting member 24. The front end of the spring member 26 is located at the wall portion 23d, and the rear end of the spring member 26 is located at the flange portion 24m. The spring member 26 urges the connecting member 24 and the ejector member 21 rearward.

[0089] The steps of rotating the stick-shaped cosmetic M out (forward) and rotating the stick-shaped cosmetic M in (backward) of the stick-shaped object rotating container 1 constructed as above are described. First, in the initial state (unused state), the connecting member 24 of the ejector mechanism 20 is not engaged with the tubular member 16 of the box 10 in the rotation direction (the second rib 24g is not engaged with the first rib 16k in the rotation direction). At this time, the front tube 12 can be removed from the main tube 23, and the ejector mechanism 20 can be replaced with the box 10.

[0090] When unscrewing the stick cosmetic M, Figure 1 (b) Fig.12 (a) and Fig.12 As shown in (b), the cover 11 is removed from the rod-shaped object container 1 to expose the front tube 12. If the ejector member 21 is pressed forward, the connecting member 24 moves forward and engages with the cylindrical member 16 in the rotation direction, and the convex portion 21g and the inclined surface 24t of the connecting member 24 (see FIG. Figure 8 )touch.

[0091] At this time, when the second rib 24g is engaged with the first rib 16k in the rotation direction, the convex portion 21g contacts the inclined surface 24t. The inclined surface 24t moves in the rotation direction relative to the advancing convex portion 21g, so that the connecting member 24 and the cylindrical member 16 rotate relative to the ejector member 21 in one direction (for example, clockwise when viewed from the rear).

[0092] When the connecting member 24 and the tubular member 16 rotate relative to each other in one direction, the tubular member 16 and the internal thread member 15 rotate synchronously, and the internal thread member 15 rotates relative to the movable body 14 in one direction. With the relative rotation in one direction, the screwing action of the screwing portion T composed of the internal thread 15b and the external thread 14b is exerted, and the movable body 14 moves forward by the screwing action. In addition, as the movable body 14 and the stick-shaped cosmetic M move forward relative to the front barrel 12, the stick-shaped cosmetic M is screwed out from the opening 12m of the front barrel 12.

[0093] The screwing amount of the stick-shaped cosmetic M in one ejection (pressing) of the ejector pin member 21 is, for example, 0.5 mm. When the pressing on the ejector pin member 21 is released, the coupling member 24 and the ejector pin member 21 move backward due to the force of the spring member 26, and the coupling member 24 separates from the tubular member 16. Then, the positions of the coupling member 24 and the ejector pin member 21 return to the positions in the initial state.

[0094] When screwing in the stick cosmetic M, Figure 1 (b) Fig.13 (a) and Fig.13 As shown in (b), the rotating member 22 is rotated relative to the main body tube 23 in a direction opposite to the aforementioned one direction (for example, counterclockwise when viewed from the rear). If the rotating member 22 is rotated relative to the main body tube 23 in the opposite direction, the convex portion 21b of the ejector member 21 moves forward along the spiral wall 22h of the rotating member 22.

[0095] At this time, the fourth rib 25p of the ratchet member 25 engages with the third rib 24p of the connecting member 24 in the rotation direction. If the rotating member 22 is rotated in the opposite direction relative to the main body tube 23, the rotating member 22, the ejector member 21, the ratchet member 25 and the connecting member 24 rotate synchronously. At this time, the ratchet member 25 rotates relative to the main body tube 23, so the inclined protrusion 25c of the ratchet member 25 passes over the inclined protrusion 23g of the main body tube 23 in the opposite direction, generating a clicking sound.

[0096] Along with this, the connecting member 24, the tubular member 16, and the internal thread member 15 rotate synchronously, and the connecting member 24, the tubular member 16, and the internal thread member 15 rotate in the opposite direction relative to the moving body 14. With this relative rotation in the opposite direction, the screwing action of the screwing portion T is exerted, and the moving body 14 retreats due to this screwing action. As the moving body 14 and the stick-shaped cosmetic M retreat relative to the front tube 12, the stick-shaped cosmetic M is screwed in.

[0097] Next, the effects of the stick-shaped object screw-out container 1 according to the present embodiment will be described in detail. The stick-shaped object screw-out container 1 includes a box portion 10 having a stick-shaped cosmetic M and a pin ejection mechanism portion 20 that can be attached to and detached from the box portion 10. Therefore, after the stick-shaped cosmetic M is used up, the box portion 10 can be removed from the pin ejection mechanism portion 20 and only the box portion 10 can be discarded. Therefore, the entire stick-shaped object screw-out container 1 does not need to be discarded, and when the box portion 10 is replaced, a new box portion 10 can be installed in the existing pin ejection mechanism portion 20. Therefore, the number of discarded parts can be reduced.

[0098] The ejector mechanism 20 includes a connecting member 24 that can rotate synchronously with the internal thread member 15 of the box 10, an ejector member 21 that advances the stick-shaped cosmetic M, and a rotating member 22 that accommodates the ejector member 21. When the ejector member 21 is pressed, the pressed force is converted into a rotational force, and the connecting member 24 and the internal thread member 15 are relatively rotated in one direction relative to the moving body 14, thereby advancing the moving body 14 and the stick-shaped cosmetic M. Therefore, the stick-shaped cosmetic M can be advanced by pressing the ejector member 21, and the stick-shaped cosmetic M can be screwed out, so that the usability of the stick-shaped object screwing out container 1 can be improved. That is, the stick-shaped object screwing out container 1 can be held with one hand and the ejector member 21 can be pressed with one hand to screw out the stick-shaped cosmetic M, so that the stick-shaped object screwing out container 1 can be set to have high usability.

[0099] Furthermore, when the pressing of the ejector pin member 21 is released and the rotating member 22 rotates relative to the main body tube 23 in the direction opposite to the above-mentioned one direction, the connecting member 24 and the internal thread member 15 rotate relative to the movable body 14 in the opposite direction, thereby retracting the movable body 14 and the stick-shaped cosmetic M. Therefore, the stick-shaped cosmetic M can be retracted by the relative rotation of the rotating member 22 relative to the main body tube 23. As described above, in the stick-shaped object screw-out container 1, the stick-shaped cosmetic M can be screwed out by ejection and the stick-shaped cosmetic M can be screwed in by rotation of the rotating member 22.

[0100] In the present embodiment, the box portion 10 has a cylindrical member 16, which can rotate synchronously with the internal thread member 15 at the rear side of the internal thread member 15 and is used to connect the connecting member 24. A first rib 16k is formed on the inner surface of the cylindrical member 16, and the first rib 16k extends along the axial direction D in which the axis of the cylindrical member 16 extends, and a second rib 24g is formed on the outer surface of the connecting member 24, and the second rib 24g engages with the first rib 16k in the rotation direction. Therefore, the internal thread member 15 of the box portion 10 and the connecting member 24 of the ejector mechanism portion 20 can be connected via the cylindrical member 16, and the internal thread member 15, the cylindrical member 16 and the connecting member 24 can be rotated synchronously.

[0101] In this embodiment, the pin ejection mechanism 20 includes a cylindrical ratchet member 25 that accommodates the connecting member 24 inside the main body tube 23. Figure 8 and Fig. 9 As shown, a third rib 24p is formed on the outer surface of the connecting member 24, and the third rib 24p extends along the axial direction D along which the axis of the ratchet member 25 extends. A fourth rib 25p is formed on the inner surface of the ratchet member 25, and the fourth rib 25p engages with the third rib 24p in the rotation direction when the connecting member 24 and the internal thread member 15 rotate in opposite directions relative to the moving body 14. Therefore, the ratchet member 25 can be rotated synchronously with the connecting member 24 and the internal thread member 15 in opposite directions.

[0102] The above is an explanation of the embodiment of the stick-shaped object screw-out container of the present invention. However, the stick-shaped object screw-out container of the present invention is not limited to the above embodiment, and can be modified within the scope of the purpose described in each technical solution, and can also be used for other purposes. That is, the structure, shape, size, material and arrangement of each component constituting the stick-shaped object screw-out container can be appropriately changed within the scope of the above purpose.

[0103] For example, in the above-mentioned embodiment, the stick-shaped object is an example of a volatile stick-shaped cosmetic M. However, in the present invention, the stick-shaped object may be a non-volatile stick-shaped cosmetic, or a stick-shaped object other than a cosmetic. The stick-shaped object involved in the present invention may be a cosmetic such as the above-mentioned lipstick, lip gloss, eye shadow or eyeliner, or may be a stationery (drawing tool) such as a marker, a medicine, or a stick-shaped object including a mud-shaped object, and these stick-shaped objects may also be applied to the stick-shaped object screw-out container involved in the present invention.
