Description

  The present invention relates to a bar-shaped cosmetic container which can accommodate a bar-shaped cosmetic such as an eyebrow, an eyeliner, an eye shadow, or a lip liner, for example.

  Conventionally, for example, a bar-shaped cosmetic container in which the various bar-shaped cosmetics are housed in a shaft cylinder so as to be able to appear and retract is obtained by moving a lifting cylinder holding the bar-shaped cosmetic material up and down in the shaft cylinder using a screw mechanism. In general, a bar-shaped cosmetic material fixed to the elevating tube is made to appear in and out of the shaft tube (see Patent Document 1). Further, in the stick-shaped cosmetic container, the stick-shaped cosmetic is placed in the stick-shaped cosmetic container so that the used stick-shaped cosmetic can be easily and reliably replaced so that the container itself can be used for a long period of time. One that is held by a separate cartridge body that is detachable has been proposed (see Patent Document 2).

  However, stick-shaped cosmetics such as lip liners have been reduced in diameter so that they can be applied precisely to the details, and because they have a glossy prescription in line with the glossy lip gloss that has recently become popular, The stick-shaped cosmetic itself is very flexible. Therefore, in manufacturing the stick-shaped cosmetic container, the melted cosmetic is directly filled and solidified in the cartridge body in which the core chuck is housed. Therefore, if the stick-shaped cosmetic material protruded from the cartridge body for use is to be immersed again in the cartridge body, the stick-shaped cosmetic material may be rubbed against the inner wall surface of the cartridge body to cause breakage or the like. That is, in such a bar-shaped cosmetic, once the bar-shaped cosmetic is protruded from the cartridge body, it is not planned to immerse the bar-shaped cosmetic in the cartridge body, and the cap is directly attached after use. I am going to do it. However, if the stick-shaped cosmetic is left protruding from the tip of the cartridge body, depending on the protruding length, the inner side of the cap abuts on the protruding tip of the stick-shaped cosmetic when the cap is attached, If the cap cannot be securely attached, or if the cap is forcibly attached, the tip of the bar-shaped cosmetic material may be crushed by the cap, the cap may stick, and the bar-shaped cosmetic material may leak out and contaminate other places. is there.

Furthermore, since the stick-shaped cosmetic container is usually carried in a small bag, it is advantageous that its overall length is short. However, if the full length of the stick-shaped cosmetic container is too short in use, it cannot be held securely with fingers, and accurate. Application work cannot be performed.
JP-A-8-353 Japanese Patent Application Laid-Open No. 11-56464

  The problem to be solved is that even in a stick-shaped cosmetic container holding a very flexible stick-shaped cosmetic, the cap can be securely attached when not in use, and the total length of the container itself is reduced. On the other hand, when used, the entire length is set to an appropriate length so that the bar-shaped cosmetic can be accurately applied.

  For this purpose, the stick-shaped cosmetic container allows a removable cartridge body that can hold the stick-shaped cosmetic material to protrude, and allows the stick-shaped cosmetic material held by the cartridge body to protrude.

And as a first feature, it is composed of a shaft tube that fits the tail plug to the rear end so as to be rotatable and impactable, and a cap that is detachable with respect to the opening at the front end of the shaft tube,
A cartridge body that is detachable and accommodates a rod-shaped cosmetic material in a projecting manner, and a tail plug, and a cartridge body retracting mechanism for retracting the cartridge body from an opening of the shaft cylinder, and a tail It is equipped with a knock mechanism that protrudes the stick-shaped cosmetic material stored in the cartridge body by hitting the stopper,
The cartridge body includes a core cylinder and a dish-shaped core chuck held in the core cylinder that holds the bar-shaped cosmetic material in the core cylinder, and the rear end side of the core cylinder is a recess opened rearward. And a gripping part made of an O-ring and a bush is fitted into the recessed part, and a through hole is formed in the bottom part of the recessed part,
The cartridge body projecting / retracting mechanism includes a cam cylinder, a slider, and a spring that is compressed or extended by sliding the slider, and the cam cylinder has a locking recess located at the apex in front of a cylindrical cam cylinder base. A cam body having a substantially triangular curved surface composed of an inclined edge connected to the front side is formed on the front side, and an engaging portion that engages with the tail plug is formed behind the slider. A locking protrusion is provided so that the locking protrusion is brought into contact with the inclined edge of the cam cylinder, and a spring is held between the locking protrusion and the inner wall of the shaft cylinder in front of the locking protrusion. As the cam barrel rotates due to the rotation of the tail plug above, the slider's locking projection advances the inclined edge of the cam cylinder and engages with the locking recess of the cam body. Fixed in state, and When the engagement between the locking projection and the locking recess is released by the reverse rotation of the stopper, the locking projection retracts the inclined edge by the elastic force of the spring, and the slider returns to the original position. Is,
The knock mechanism includes a knock cylinder that is inserted through a movable push rod, and a holder cylinder into which the distal end side of the knock cylinder is inserted, and the knock cylinder holds a three-part connecting portion at the distal end thereof, A spring is held between the projecting portion projecting radially outward in the middle and the inner wall of the holder cylinder, and the holder cylinder has a tri-slot hole in front of the tip of the inserted knock cylinder, and is fixed to the tri-slot hole. A ring that is detachable with a frictional force of is inserted, and a three-piece split is inserted so as to be detachable with respect to the ring, and a ring stopper is provided in front of the ring. A locking protrusion is provided on the outer side, and is loosely fitted in a guide groove provided in the axial direction on the inner wall surface of the shaft cylinder. When the cartridge body is advanced by the cartridge body retracting mechanism, the holder cylinder Are those stop flange is formed by positioned to leave a gap with respect to the earliest portion of the groove guiding,
The rear end of the knock cylinder of the knock mechanism is fixed to the slider, the rear end of the cartridge body is connected to the front end of the holder cylinder, and the push rod of the knock cylinder is formed at the bottom of the recessed portion of the core cylinder. By contacting the core chuck outer bottom through the through hole,
As the slider and the knock cylinder are rotated by the rotation of the tail plug, the three-pieces inserted into the ring advance while holding the push rod, and the holder having the three-holes into which the ring is inserted by the advance of the three-piece The cylinder is advanced, the connected cartridge body is advanced, the cartridge body is protruded from the shaft cylinder, and further, as the knock cylinder is advanced by striking the tail plug, the three-prong If the holder cylinder and the cartridge body are moved forward by the advancement of the holder cylinder, if the locking projection of the holder cylinder stops when it reaches the forefront of the guide groove, the split and the ring protrude forward from the split hole while holding the push rod, After that, if the ring stops moving forward with the ring stopper, only the three parts are expanded and moved forward to release the push rod and stop the tail plug impaction. The knock cylinder, the split and ring, the holder cylinder, and the tail plug are restored by the elastic force of the spring between the projection of the knock cylinder and the inner wall of the holder cylinder. As the slider, which is based on the disengagement with the locking recess, and the knock cylinder are retracted, the three-pieces inserted in the ring while holding the push bar are retracted, and the holder cylinder is retracted by the reverse of the three-pieces. Thus, the connected cartridge body is retracted into the shaft cylinder.

Therefore, when the tail plug is rotated, the cam cylinder integrated with the tail plug rotates, so that the slider moves in the direction of the opening of the shaft cylinder while compressing the spring by the locking protrusion along the inclined edge of the cam body. The slider moves forward, and then the locking projection of the slider is locked by being locked in the locking recess at the tip of the cam body. At that time, the knock cylinder that holds the rear end in the slider pushes the holder cylinder forward through the three parts, and further the holder cylinder pushes the cartridge body in the same direction to advance, so that the cartridge body is pivoted. It protrudes from the opening of the tube and is fixed.
When the tail plug is struck in that state, the holder cylinder and further the cartridge body advance in accordance with the advancement of the knock cylinder, but the engagement between the locking projection edge of the boulder cylinder and the tip of the guide groove of the shaft cylinder After the advancement of the holder cylinder is stopped, the three-pronged part moves forward from the three-pronged hole of the holder cylinder while holding the pushrod together with the ring, so that the advanced pusher pushes the core chuck that contacts the outer bottom part, The cosmetic protrudes from the opening.
Furthermore, even if the impact of the tail plug is stopped, the push rod that comes into contact with the outer bottom of the core chuck is gripped by the gripping part that is fitted into the recessed part of the core tube until the third part is inserted into the third hole. Therefore, the contact between the push rod and the outer bottom portion of the core chuck is always maintained without retreating.

  After use, when the tail plug is rotated in the reverse direction, the locking projection of the slider is released from the locking recess at the tip of the cam body, and the spring compressed by the locking projection of the slider is extended. The shaft tube moves backward along the inclined edge of the cam tube. Then, the knock cylinder integrated with the slider pulls the holder cylinder through the three parts, and the holder cylinder pulls the cartridge body in the same direction to retract, so that the cartridge body is immersed in the shaft cylinder.

  When exchanging the bar-shaped cosmetic, the cartridge body is pulled out from the holder cylinder of the knock mechanism by pulling the cartridge body with the cartridge body protruding most from the opening of the shaft cylinder. Just pull it out from the push rod. After pushing the push rod protruding from the holder cylinder back into the holder cylinder, the new cartridge body is connected to the tip of the holder cylinder, and the push rod is inserted into the through hole in the grip portion of the cartridge body and the inner bottom portion. Concatenated to complete.

Therefore, as a second feature, it is composed of a shaft tube that rotatably fits the tail plug at the rear end, and a cap that is detachable with respect to the opening in front of the shaft tube,
A cartridge body that is detachable and accommodates the rod-shaped cosmetic material in a projecting manner, a rotary cylinder that is integrated with the tail plug, and that allows the cartridge body to be retracted and retracted from the opening of the shaft cylinder, and A receiving cylinder that externally covers both the cartridge body and the rotating cylinder;
The shaft tube has a thick wall portion with a thick wall at the front side and a thin wall portion with a small wall thickness at the rear side, and a peripheral step is formed on the inner wall surface between the thick wall portion and the thin wall portion. And forming a guide groove that forms a guide groove rear end portion in the peripheral step portion on the thick-walled portion side in the longitudinal direction of the shaft cylinder,
The cartridge body has a core cylinder, a screw shaft composed of a base portion having a meshing hole and a male screw portion, holds a stick-shaped cosmetic in the core chuck body, has a female screw hole in the shaft portion, and is engaged with the outer periphery of the rearmost end. A male chuck of a screw shaft is formed in the female screw hole in the shaft portion of the core chuck in the core cylinder, the core chuck including a core chuck that projects the protrusion and a guide groove that loosely fits and guides the engaging protrusion. The outer periphery of the screw shaft is externally attached to the outer periphery of the base portion of the screw shaft so as to be able to rotate synchronously while being inseparable in the axial direction,
The rotating cylinder is provided with an engaging pin that protrudes outward at the rear end, and is provided with an engaging portion that can be engaged with an engaging hole formed in the base of the screw shaft of the cartridge body at the tip.
The tail plug is composed of a tail plug main body protruding rearward of the shaft cylinder and a cylindrical insertion portion formed by engraving a spiral cam groove provided on the side surface in the circumferential direction at the tip. ,
The receiving tube has a protruding portion that protrudes outward and loosely fits in a guide groove carved in the shaft tube,
The tail plug and the rotating cylinder are integrated by loosely fitting the engaging pin of the rotating cylinder into the helical cam groove of the tail plug, and the rotating cylinder and the screw shaft of the cartridge body are connected to the rotating cylinder. The engagement portion of the tip and the engagement hole of the screw shaft are engaged with each other, and the receiving tube and the rotating tube cannot be detached in the axial direction and are fitted so that they can rotate synchronously. The cartridge cylinder can be attached and detached in the axial direction, but is fitted so that individual rotation is impossible.

  For this reason, when the tail plug is rotated in one direction, the rotating cylinder integrated with the tail plug advances in the longitudinal direction of the shaft cylinder, so that the receiving cylinder and the cartridge body are guided by the guide groove on the inner wall surface of the shaft cylinder. By moving forward in the direction, the cartridge body projects from the opening of the shaft cylinder. Then, when the engaging pin of the rotating tube reaches the locking groove of the insertion portion of the tail plug, the tail plug and the rotating tube are rotated, but at that time, the rotating tube is fitted. Since the receiving tube is loosely fitted in the guide groove of the shaft tube, it does not rotate, and only the rotating tube rotates. Then, the rotation of the rotating cylinder is transmitted to the screw shaft by meshing between the meshing portion and the meshing hole of the screw shaft. However, a rotating cylinder is externally mounted on the outer periphery of the base of the screw shaft, and the rotating cylinder is fitted with the receiving cylinder so that individual rotation is impossible. Only the screw shaft rotates without rotating. Then, by having the engaging protrusion loosely fitted in the guide groove of the non-rotating stop cylinder and rotating the male screw portion of the screw shaft in the female screw hole of the non-rotating core chuck, the core chuck is Since the inside of the core cylinder moves forward in accordance with the guide groove of the rotation stop cylinder, the bar-shaped cosmetic material protrudes from the opening of the core cylinder.

  In addition, after use, by rotating the tail plug in the reverse direction, the rotating cylinder is retracted in the insertion part of the tail plug, that is, in the shaft cylinder, and the receiving cylinder is fitted to the rotating cylinder so as not to be detached in the axial direction. Further, the cartridge body is moved into the shaft cylinder by the rotation of the rotation cylinder fitted to the receiving cylinder and the screw shaft fitted to the rotation cylinder so as not to be detached in the axial direction. Immerse in. At this time, by sufficiently immersing the cartridge body in the shaft tube, the protrusion of the receiving tube is detached from the guide groove of the shaft tube. Therefore, even if the tail plug is further rotated in the reverse direction thereafter, the receiving cylinder and the cartridge body rotate together with the rotating cylinder, and the rotation of the tail plug is not transmitted to the core chuck of the cartridge body. It is possible to prevent breakage due to immersion.

  When exchanging the bar-shaped cosmetic material, the cartridge body is pulled with the cartridge body most protruded from the opening of the shaft cylinder, and the engagement between the meshing portion of the rotary cylinder and the meshing hole of the screw shaft is performed. What is necessary is just to dissociate the fitting with a receiving cylinder and a rotation cylinder. Then, the engagement hole of the screw shaft of the new cartridge body is engaged with the engagement portion at the tip of the rotating cylinder in the axial cylinder, and the receiving cylinder and the stop cylinder are engaged to complete.

  The invention of the present application has an excellent effect that the diameter-reduced and very flexible bar-shaped cosmetic can be made to appear and disappear more smoothly than the bar-shaped cosmetic container, and the replacement can be easily and reliably performed by the cartridge body. Have

  Reference numeral 1 shown in FIGS. 1 to 6 denotes a stick-shaped cosmetic container according to the first embodiment of the present invention. The stick-shaped cosmetic container 1 includes a stopper tube 16 at the rear end and a shaft tube 3 into which a tail plug 14 protruding rearward is fitted, and a cap that is detachable from the opening 3 ′ at the front end of the shaft tube 3. 2. (In this specification, the direction is indicated with the direction of the tail plug 14 of the bar-shaped cosmetic container 1 as the back and the direction of the opening 3 'of the shaft tube 3 as the front or the front.)

  A cartridge body 5, which is detachable and accommodates the bar-shaped cosmetic 13 so as to be protruded, is integrated with the tail plug 14 and protrudes and retracts from the opening 3 ′ of the shaft tube 3. A cartridge body projecting / retracting mechanism A and a knock mechanism B for projecting the bar-shaped cosmetic material 13 accommodated in the cartridge body 5 from the cartridge body 5 by hitting the tail plug 14 are provided.

  Here, the tail plug 14 is formed with a recessed hole 15 that is integrally engaged with an engaging portion 21 of a cam cylinder 17 (described later) protruding from the rear end of the shaft cylinder 3. is there.

  The cartridge body 5 includes a core cylinder 6 and a core chuck 7, and the core cylinder 6 has a stepped portion for holding the dish-shaped core chuck 7 for holding the bar-shaped cosmetic 13 on the rear end side. Further, the rear end has a substantially H-shaped cross section in the front-rear direction, and a holding portion 12 including an O-ring 10 and a bush 11 is formed in a recessed portion 8 formed to open to the rear end side of the substantially H-shaped section. A through hole 9 that is formed and penetrates in the front-rear direction is formed in a portion that becomes the bottom of the recessed portion 8.

  The cartridge body projecting / retracting mechanism A comprises a cam cylinder 17, a slider 25, and a spring 27 that is compressed or extended by sliding of the slider 25. The cam cylinder 17 includes a locking recess 19 formed from a smooth curved surface located at the apex, and a substantially triangular curved cam body 18 having a vertical edge 24 and an inclined edge 20 connected to the locking recess 19. An engaging portion 21 that engages with the tail plug 14 is disposed behind the cam tube base 23 and disposed on the cylindrical cam tube base 23 so that the two locking recesses 19 face each other. Is formed. The slider 25 has a substantially cylindrical shape with a substantially H-shaped cross section in the front-rear direction. The slider 25 has a locking projection 26 that moves along the inclined edge 20 of the cam cylinder 17 facing the center of the outer peripheral surface. It is provided by protruding. The spring 27 is stretched between the locking projection 26 of the slider 25 and a stepped portion 43 provided inward at a substantially intermediate portion of the shaft tube 3.

  A locking edge 22 projecting radially outward is formed on the side peripheral surface of the cam cylinder base 23 in the opposite direction in parallel to the shaft, and a stopper cylinder fitted to the rear end of the shaft cylinder 3. A locking ridge 16 ′ that protrudes radially inward is formed in a position opposite to the inner wall surface of 16 in parallel with the shaft. For this reason, when the cam cylinder 17 is rotated by rotating the tail plug 14, the locking edge 22 of the cam cylinder 17 and the locking protrusion 16 'of the stopper cylinder 16 are engaged with each other at a predetermined rotation angle. Prevents the tail plug 8 from rotating. As a result, excessive rotation of the tail plug 14 is suppressed, so that the inclined edge 20 of the cam cylinder 17 pushes the locking projection 26 of the slider 25, and the forward movement of the slider 25 and the advanced locking projection. Engagement of the cam body 18 with the locking recess 19 is ensured.

  The knock mechanism B includes a holder 28, a guide cylinder 33, and a knock cylinder 40. The tip 34 of the guide cylinder 33 is fitted into the holder 28 to be integrated, and the rear end of the knock cylinder 40 is a slider. The tip is inserted into the guide tube 33. The holder 28 has four locking protrusions 32 that are loosely fitted in the four guide grooves 4 that are engraved on the inner wall surface of the shaft tube 3 at equal intervals in the axial direction on the outer peripheral surface. A cylindrical body having a substantially H-shaped cross section having connecting holes 29, 29 'that open in the direction, and the inner bottoms of the connecting holes 29, 29' communicate with each other through the through holes 30 and open in the rearward direction. A step portion 31 is formed in 29 '. Even when the holder 28 is advanced to the maximum by the operation of the cartridge body retracting mechanism A, the locking protrusion 32 of the holder 28 is positioned at the forefront of the guide groove 4 formed in the shaft cylinder 3. Instead, the guide groove 4 is positioned so that a slight gap remains. The guide tube 33 includes a small-diameter tip portion 34 and a large-diameter guide tube base portion 37, and a step portion 38 is provided inside the guide tube base portion 37, so that the rear inner diameter of the guide tube base portion 37 is large. Is set. An opening 34 ′ that is a three-slotted hole is provided at the tip of the tip 34, and a ring 35 that can be projected and retracted from the opening 34 ′ is fitted into the opening 34 ′. A tri-section 36 is provided, which is inserted into and retractable from 35 and is openable and closable, and has a connecting portion 36 ′ at its rear edge fixed to the tip of the knock cylinder 40. The tip 34 is engaged with and integrated with the step 31 in the connecting hole 29 ′ behind the holder 28. On the other hand, the knock cylinder 40 moves within the guide cylinder 33 and the holder 28 in accordance with the movement of the slider 25 in the front-rear direction, and a push bar 42 is inserted through the inside of the guide cylinder 33 and the holder 28. It protrudes forward from 28 and abuts against the outer bottom 7 ′ of the core chuck 7 in the core cylinder 6 of the cartridge body 5. The knock cylinder 40 has a spring 39 integrally provided in the guide cylinder 33. The tip of the spring 39 is provided at a step portion 38 provided in the guide cylinder base 37 of the guide cylinder 33, and the rear end thereof is provided. The knock cylinder 40 is engaged with a protruding portion 41 that protrudes in the radially outward direction at a substantially intermediate portion thereof.

  Therefore, in the stick-shaped cosmetic container 1, the tail plug 14, the cartridge body retracting mechanism A, the knock mechanism B, and the cartridge body 5 are engaged with the recessed hole 15 of the tail plug 14 and the engaging portion 21 of the cam cylinder 17. The cartridge body 5 is integrally connected by holding the rear end of the knock cylinder 40 in the slider 25 and fitting the rear end of the cartridge body 5 to the connecting hole 29 opened to the front of the holder 28. The push bar 42 held in the knock cylinder 40 passes through the opening 34 ′ of the guide cylinder 33, the through hole 30 of the holder 28, and the through hole 9 provided at the rear end of the core cylinder 6, respectively. It is in contact with the outer bottom portion 7 ′ of the core chuck 7 provided in the cylinder 6.

As mentioned above, since the stick-shaped cosmetic container 1 in Example 1 of this invention is comprised, a user uses the said stick-shaped cosmetic container 1 for use as follows.
That is, the cap 2 that is mounted so as to close the opening 3 ′ of the shaft tube 3 in order to maintain the sealing inside the shaft tube 3 is detached from the shaft tube 3 by pulling.
Next, the locking edge 22 of the cam cylinder 17 integrated with the tail plug 14 contacts the locking protrusion 16 ′ of the locking cylinder 16 with the tail plug 14 protruding and held at the rear end of the shaft cylinder 3. Rotate until Due to the rotation of the cam cylinder 17 by the rotation of the tail plug 14, the slider 25 advances while the locking protrusion 26 protruding from the outer periphery compresses the spring 27 along the inclined edge 20 of the cam body 18. At this time, the knock cylinder 40 holding the rear end in the slider 25 is also pushed by the slider 25 and similarly advances in the shaft cylinder 3.
Further, the locking projection 26 of the slider 25 is fixed by moving along the inclined edge 20 of the cam body 18 and then engaging with a locking recess 19 at the tip of the cam body 18. In this state, the knock cylinder 40 is also moved forward and fixed by the moving distance of the slider 25. As the knock cylinder 40 advances, the connecting portion 36 'fixed to the tip of the knock cylinder 40 advances. As the connecting portion 36 ′ advances, the three-piece split 36 held in the ring 35 provided at the opening 34 ′ at the tip of the guide cylinder 33 advances while holding the push rod 42. 36 also advances the guide cylinder 33 through the ring 35, and the holder 28 for loosely fitting the locking protrusion 32 into the guide groove 4 formed on the inner wall surface of the shaft cylinder 3 by further advancement of the guide cylinder 33. Then, the shaft cylinder 3 is advanced, and the guide groove 4 is fixed with a slight gap left at the tip of the locking protrusion 32.
As a result, since the rear end of the core cylinder 6 constituting the cartridge body 5 is fitted in the connecting hole 29 that opens to the front of the holder 28, the cartridge body 5 is It protrudes from the shaft tube 3 and is fixed.

When the tail plug 14 is struck, the push bar 42 held inside the knock cylinder 40 is gradually advanced in the shaft cylinder 3 by the knock mechanism B. That is, by striking the tail plug 14 once, the slider 25 moves forward by the one striking part (a gap left at the tip of the locking protrusion 32 of the holder 28 in the guide groove 4), The knock cylinder 40 whose rear end is held in the slider 25 is also pushed forward by the same gap. At this time, the knock cylinder 40 advances the connecting section 36 'of the three-piece split 36 held at the tip thereof, thereby advancing the guide cylinder 33 integrated with the three-piece split 36 and the ring 35, and further the guide cylinder Although 33 advances the holder 28, as described above, when the locking projection 32 of the holder 28 reaches the forefront of the guide groove 4, the holder 28 cannot be further advanced. By the advance of the part 36 ′, the three-split 36 fitted together with the ring 35 with respect to the opening 34 ′ of the tip 34 of the guide cylinder 33 holds the push bar 42 together with the ring 35 while opening the opening 34 of the guide cylinder 33. As a result, the push rod 42 is moved forward.
In addition, when the ring 35 and the three-piece 36 are protruded from the opening 34 ′ by a certain amount, the step 31 formed in the connection hole 29 ′ of the holder 28 becomes a ring stopper, and only the ring 35 is connected to the step 31. Since it comes into contact with and stops, it is separated from the split 36, and the split 36 further advances and expands from the stopped ring 35 to release the grip on the push bar 42. That is, the push rod 42 moves forward while resisting the pressure of the holding portion 12 by the O-ring 10 and the bush 11 of the cartridge body 5 while being held by the three-piece 36 as the knock cylinder 40 moves forward by hitting the tail plug 14. To do. Therefore, after the split 36 is expanded and the gripping by the push rod 42 is released, the push rod 42 is gripped only by the grip portion 12 by the O-ring 10 and the bush 11 of the cartridge body 5.
Thereafter, when the impact on the tail plug 14 is stopped, the slider 25 and the knock cylinder 40 as well as the tail plug 14 are retracted by the elastic force of the compressed spring 39 in the guide cylinder 33, and the knock cylinder 40 Since the connecting portion 36 ′ of the three-split portion 36 is fixed to the tip portion, the three-split portion 36 also retracts in the shaft tube 3 at the same time. At this time, as the split 36 is retracted, it fits into the opening 34 ′ of the guide cylinder 33 together with the ring 35 while being fitted into the ring 35 that has not yet been immersed in the opening 34 ′ of the guide cylinder 33.
As a result, the widened split 36 is closed and the push bar 42 is gripped again. That is, the push rod 42 is held only by the O-ring 10 and the bush 11 of the cartridge body 5 until the three-piece 36 is fitted into the opening 34 ′ of the guide cylinder 33, and the three-piece 36 together with the ring 35 opens the guide cylinder 33. Since the push rod 42 is gripped only after being inserted into the portion 34 ′, the push rod 42 once advanced is not retracted by the three-piece split 36 itself.
Accordingly, the core chuck 7 in the core cylinder 6 is also pressed by the advanced push bar 42 to advance, so that the bar-shaped cosmetic 13 protrudes from the opening 6 ′ of the core cylinder 6.
In order to make the stick-shaped cosmetic material 13 protrude more from the opening 6 ′ of the core tube 6, it is only necessary to repeat the impact against the tail plug 14.

After use, when the tail plug 14 is rotated in the opposite direction, the cam cylinder 17 rotates in the same direction, so that the engagement between the locking projection 26 of the slider 25 and the locking recess 19 of the cam body 18 is released. It becomes.
As a result, the spring 27 compressed by the locking projection 26 of the slider 25 extends toward the rear of the shaft cylinder 3, so that the slider 25 automatically retracts inside the shaft cylinder 3.
At this time, the guide cylinder 33 and the holder 28 constituting the knock mechanism B are similarly pulled backward in the shaft cylinder 3 through the knock cylinder 40 fixed to the slider 25, the three-piece split 36, and the ring 35, and thus retracted. The cartridge body 5 connected integrally with the holder 28 is quickly immersed in the shaft cylinder 3.

  The cartridge body 5 holding the bar-shaped cosmetic material 13 is replaced by first pulling the cartridge body 5 by pulling the cartridge body 5 with the cartridge body 5 most protruded from the opening 3 ′ of the shaft 3. The cartridge body 5 can be taken out because it is pulled out from the connecting hole 29 on the front side of the holder 28 and dissociated by pulling out the push bar 42 protruding from the holder 28 from the grip portion 12. Then, after the push bar 42 in the advanced state is pushed back into the shaft cylinder 3 with a finger or the like, a new cartridge body 5 is inserted from the opening 3 ′ of the shaft cylinder 3, and the grip portion of the cartridge body 5 is The push rod 42 is inserted into the core 12 until it comes into contact with the outer bottom 7 ′ of the core chuck 7, so that both are integrated.

It is a cylinder. The base portion 116 of the screw shaft 115 has a meshing hole 118 that opens rearward and is inserted into the rear end side of the stop cylinder 138. On the other hand, the front end of the stop cylinder 138 is in contact with the rear end of the core chuck body 120, and the engagement protrusion 119 of the core chuck 112 is loosely fitted in the guide groove 141. Further, the screw shaft 115 and the stop cylinder 138 include a locking peripheral edge 121 provided so as to protrude outward in the vicinity of the rear end edge of the base portion 116 of the screw shaft 115, and a rear end edge of the stop cylinder 138. It is formed with a locking recess 142 formed to be concaved so as to correspond to the locking peripheral edge 121 on the inner side in the vicinity, and it cannot be detached in the axial direction, and can rotate synchronously in the circumferential direction. It is united by the rotation fitting part 145 formed by fitting.

  The rotating cylinder 123 is provided with a meshing portion 124 that can be meshed with a meshing hole 118 formed in the base portion 116 of the screw shaft 115 of the cartridge body 110, and a circular portion at a substantially central front portion. A projecting portion 126 projecting outward in the circumferential direction is provided, and two engaging pins 125 are provided projecting outward at positions facing each other at the rear end, and then cut in the longitudinal direction from the rear end edge. 127 is formed.

  Further, the tail plug 134 includes a tail plug main body 135 protruding rearward of the shaft tube 103 and a cylindrical insertion portion 136 that is rotatably inserted into the shaft tube 103, and on the side surface of the insertion portion 136. Two cam grooves 137 that penetrate the inside and the outside and rotate approximately half-turn in a left spiral toward the opening 103 ′ side of the shaft tube 103 (that is, toward the front) are opposed to each other. A locking groove 137 ′ is provided at the tip of each cam groove 137 on the left side of each cam groove 137 in the tip direction and in the circumferential direction of the cylindrical insertion portion 136. Note that the rear end side of the cam groove 137 has a protruding portion 131 provided on the receiving cylinder 130, which will be described later, protruding outwardly more than the length of the guide groove 107 of the loosely fitting shaft cylinder 103. The rear end of the tail plug body 134 is extended to the rear of the insertion portion 136 so as to be able to move.

  The rotating cylinder 123 and the tail plug 134 are integrated as follows. That is, first, the spring 144 is housed in the cylindrical insertion portion 136 of the tail plug 134. Next, by pushing the rear side of the rotating cylinder 123 in the radial direction, the notch 127 formed in the longitudinal direction from the rear end edge of the rotating cylinder 123 is deformed to reduce the diameter of the rotating cylinder 123. Then, the rotary cylinder 123 is inserted into the insertion part 136 of the tail plug 134 from the side of the engagement pin 125, and each engagement pin 125 is engraved in the insertion part 136 of the tail plug 134. And the spring 144 is held at the rear end edge of the rotating cylinder 123. Then, in the rotating cylinder 123 and the tail plug 134 that are integrated while holding the spring 144, the protruding portion 131 provided on the receiving cylinder 130, which will be described later, has a protruding portion 131 that protrudes outwardly. As described above, the rear end side of the cam groove 137 is excessive even when the rotary cylinder 123 is deeply inserted into the insertion portion 136 of the tail plug 134 so that the length of the guide groove 107 is sufficient to move. Since the rear end of the rotary cylinder 123 is extended rearward, a clearance 148 is formed between the rear end edge of the rotary barrel 123 and the tail plug body 135 of the tail plug 134 by the elasticity of the spring 144. A relief 148 is also formed between the rear end edge of the projection 126 of the 123 and the tip edge of the tail plug 134, and the rotary cylinder 123 can be moved by the length of the relief 148 in the longitudinal direction of the shaft cylinder. It has become.

  The receiving tube 130 has a cylindrical shape and is provided with a protruding portion 131 that protrudes inward and outward at a substantially central portion thereof, and the protruding portion 131 of the protruding portion 131 is formed on the inner side of the shaft tube 103. The wall surface 104 is loosely fitted so as to be movable in a guide groove 107 formed in the longitudinal direction of the shaft cylinder. On the other hand, the inwardly protruding portion of the protrusion 131 is provided around the inner wall of the receiving cylinder 130, the front side of which is in contact with the rear end edge of the locking cylinder 138 of the cartridge body 110, and the rear side Is in contact with the step portion 129 of the rotating cylinder 123. Further, the front end edge of the receiving cylinder 130 itself is in contact with the flange portion 139 of the rotating cylinder 138, and the rear end edge is in contact with the protruding portion 126 of the rotating cylinder 123. Further, the receiving tube 130 and the rotating tube 123 are provided in the vicinity of the rear end edge of the receiving tube 130 and the locking peripheral edge 128 provided so as to protrude in the circumferential direction in front of the protruding portion 126 of the rotating tube 123. It is formed with a locking recess 133 that is recessed so as to correspond to the locking peripheral edge 128, and cannot be detached in the axial direction, but fitted so that it can rotate synchronously in the circumferential direction. It becomes united by the rotation fitting part 146 which becomes. In addition, the retaining cylinder 138 and the receiving cylinder 130 are provided in the vicinity of the rear end edge of the retaining cylinder 138 in the circumferential direction so as to protrude in the circumferential direction, and in the vicinity of the front end edge of the receiving cylinder 130. It is formed with a locking recess 133 that is recessed so as to correspond to the locking peripheral edge 143, and is integrated by a detachable fitting portion 147 that can be attached and detached in the axial direction. The rotating knurls 140 provided around the rear outer peripheral surface of the locking peripheral edge 143 and the rotating knurls 132 provided around the inner wall surface in front of the projecting portion 131 of the receiving tube 130 are engaged with each other, thereby enabling individual rotation. It is united as impossible.

That is, as shown in FIG. 6, the rotating cylinder 123, the cartridge body 110, and the receiving cylinder 130 are integrated.
More specifically, the rotating cylinder 123 and the screw shaft 115 of the cartridge body 110 are formed by an engagement portion 124 disposed at the tip of the rotating tube 123 and an engagement hole 118 formed in the base portion 116 of the screw shaft 115. The rotating cylinder 123 and the receiving cylinder 130 are connected by the rotation fitting portion 146, and the rotation cylinder 138 and the receiving cylinder 130 of the cartridge body 110 are connected by the attachment / detachment fitting portion 147 and the rotation knurl 140, respectively. 132 are integrated with each other. Also in the cartridge body 110, as described above, the screw shaft 115 and the non-rotating cylinder 138 are integrated by the rotation fitting portion 145.

Note that the outward projecting portion of the projecting portion 131 projecting from the receiving tube 130 passes through the guide groove 107 formed in the longitudinal direction of the shaft tube in the thick portion 105 of the inner wall surface 104 of the shaft tube 103. It becomes movable in the direction. However, the guide groove 107 is broken by forming the guide groove rear end portion 108 at the peripheral step portion 109 formed on the inner wall surface 104 of the shaft tube 103 as described above. Accordingly, the outward projecting portion of the protrusion 131 that is loosely fitted in the guide groove 107 so as to be movable in the front-rear direction is detached from the guide groove rear end portion 108 when it is most retracted in the shaft tube 103. Thus, the outward projecting portion of the protruding portion 131 detached from the guide groove 107 is rotatable in the circumferential direction of the shaft tube 103 at the peripheral step portion 109. As a result, even if the user excessively rotates the tail plug 134 counterclockwise, the outward projecting portion of the projecting portion 131 projecting from the receiving tube 130 is detached from the guide groove 104 of the shaft tube 103. The rotating cylinder 123, the screw shaft 115, and the core chuck 112 rotate together with the rotation of the tail plug 134, and the retraction of the core chuck 112 by the screw shaft 115 is prevented, and the rod-shaped cosmetic material 122 is prevented from being damaged. It will be possible.
In addition, the rotating cylinder 123 integrated with the receiving cylinder 130 via the rotation fitting portion 146 is pushed forward from the tail plug 134 by the elasticity of the spring 144 built in the tail plug 134. As described above, the clearance 148 is formed between the rear end edge of the rotary cylinder 123 and the tail plug main body 135, and the rear end edge of the protrusion 126 of the rotary cylinder 123 and the tip of the tail plug 134 are formed. Since the relief 148 is also formed between the edges, the rotary cylinder 123 can move backward by the length of the relief 148. As a result, the moving distance of the rotating cylinder 123 due to the rotation of the tail plug 134 is larger than the length of the guide groove 107 in which the protruding part 131 protruding from the receiving cylinder 130 is loosely fitted. Since the length is surely long, even when there is an error in the dimensions of each member during production, the outward projecting portion of the protruding portion 131 protruding from the receiving tube 130 is most retracted in the shaft tube 103 Therefore, it is surely separated from the guide groove 107.
Further, since the rotating cylinder 123 is pushed forward by the elastic force of the spring 144 provided in the tail plug 134, the receiving cylinder 130 integrated with the rotating cylinder 123 is also pushed in the same direction. Yes. Therefore, even when the receiving tube 130 is most retracted in the shaft tube 103 and is separated from the guide groove 107, the protruding portion 131 protruding from the receiving tube 130 that rotates synchronously by rotating the tail plug 134 clockwise. When the position of the outwardly projecting portion matches the guide groove rear end portion 108, it is loosely fitted into the guide groove 107 again by the elastic force of the spring 144.

As described above, since the stick-shaped cosmetic container 101 according to the second embodiment of the present invention is configured, the user uses the stick-shaped cosmetic container 101 for use as follows.
That is, the cap 102 that is mounted so as to close the opening 103 ′ of the shaft tube 103 in order to maintain the sealing inside the shaft tube 103 is detached from the shaft tube 103 by pulling.
Next, when the tail plug 134 that is rotatably fitted to the rear end of the shaft tube 103 is rotated 180 degrees to the right at the maximum, the receiving tube 130 is pushed forward by the elastic force of the spring 144 via the rotating tube 123. Therefore, it is possible to rotate in the circumferential direction of the shaft tube 103 at the peripheral step portion 109 in a state where the guide groove 107 is separated from the guide groove rear end portion 108 of the guide groove 107 formed on the inner wall surface 104 of the shaft tube 103. The outward projecting portion of the protruding portion 131 of the receiving tube 130 is loosely fitted into the guide groove 107 from the guide groove rear end portion 108 formed in the peripheral step portion 109.
Then, the insertion part 136 of the tail plug 134 guides the engagement pin 125 of the rotary cylinder 123 loosely fitted in the cam groove 137 that rotates approximately half a spiral of the insertion part 136 along the cam groove 137. Thus, the rotating cylinder 123 moves forward, and finally the engaging pin 125 of the rotating cylinder 123 engages with the locking groove 137 ′ at the tip of the cam groove 137. At this time, since the locking groove 137 ′ is provided in the circumferential direction, the rotary cylinder 123 cannot advance any further. As the rotating cylinder 123 advances, the receiving cylinder 130 integrated with the rotating cylinder 123 also advances while loosely fitting the protruding portion 131 of the protruding portion 131 into the guide groove 107.
As the rotary cylinder 123 and the receiving cylinder 130 move forward, the cartridge body 110 also moves forward and protrudes from the opening 103 ′ of the shaft cylinder 103 and is held firmly. At this time, since the engaging pin 125 of the rotating cylinder 123 is engaged with a locking groove 137 ′ provided in the circumferential direction of the insertion portion 136 at the tip of the cam groove 137, the tail plug 134 is rotated clockwise. Even if the cartridge body 110 does not move forward, the cartridge body 110 protruding from the opening 103 ′ of the shaft tube 103 does not move forward even when a pressing force from the front acts on the cartridge body 110. It is not pushed back into the tube 103.
Then, when the tail plug 134 is further rotated clockwise, the engagement pin 125 of the rotary cylinder 123 is first engaged with the locking groove 137 ′ of the cam groove 137 of the tail plug 134. The cylinder 123 rotates together. The rotation of the rotating cylinder 123 causes the integrated receiving cylinder 130 to rotate in synchronization with the rotation fitting portion 146. However, the protrusion 131 of the receiving cylinder 130 protrudes outward. Since the portion is loosely fitted in the guide groove 107 of the shaft tube 103, the receiving tube 130 cannot rotate, and only the rotating tube 123 rotates against the friction in the rotation fitting portion 146. Become. On the other hand, the rotation of the rotating cylinder 123 is transmitted to the screw shaft 115 by the engagement of the engagement portion 124 and the engagement hole 118. The screw shaft 115 is integrated with a rotation fitting portion 145 so as to be able to rotate in synchronization with the rotation cylinder 138, but the rotation cylinder 138 is connected to the receiving cylinder 130 with the rotation knurls 132 and 140. It is united so that individual rotation is impossible by meshing. That is, the rotation of the tail plug 134 is transmitted to the screw shaft 115 through the engagement between the engagement portion 124 disposed at the tip of the rotary cylinder 123 and the engagement hole 118 of the screw shaft 115 of the cartridge body 110. At this time, the rotation cylinder 138 also tries to rotate in synchronization with the rotation of the screw shaft 115, but the rotation cylinder 138 has a protruding portion 131 protruding outward from the guide groove 107 of the shaft cylinder 103. Since it is integrated with the receiving cylinder 130 which cannot be rotated by loosely fitting with it, it is integrated so that individual rotation becomes impossible by meshing of the rotation knurls 132 and 140, so that the screw does not rotate. The shaft 115 rotates against the friction at the rotation fitting portion between the shaft 115 and the stop cylinder 138.
As a result, the core chuck 112 having the female screw hole 114 screwed with the male threaded portion 117 of the rotating screw shaft 115 is loosely moved into the guide groove 141 of the stop cylinder 138 where the engaging protrusion 119 of the core chuck 112 does not rotate. Since it is fitted, the bar-shaped cosmetic 122 guided forward and held by the core chuck 112 protrudes from the opening 111 ′ of the core cylinder 111.

After use, when the tail plug 134 is rotated in the reverse direction (left rotation), the engagement between the engaging pin 125 of the rotating cylinder 123 and the locking groove 137 ′ at the tip of the cam groove 137 is first released.
Then, by further rotating, the cam groove 137 of the tail plug 134 is loosely fitted and rotated while guiding the engaging pin 125 of the rotating cylinder 123, and the rotating cylinder 123 moves backward in the shaft cylinder 103. To do. At this time, due to the friction of the rotation fitting portion 146 between the receiving cylinder 130 and the rotating cylinder 123, the cartridge body 110 is retracted integrally, so that the cartridge body 110 is also retracted in the shaft cylinder.
As a result, the cartridge body 110 is quickly immersed in the shaft tube 103.
Since the rear end portion of the cam groove 137 is extended as described above, when the tail plug 134 is rotated counterclockwise, the receiving cylinder is loosely fitted in the guide groove 107 of the inner wall surface 104 of the shaft cylinder 103. The projecting portion 131 projecting outwardly from the projecting portion 130 can be retracted by an amount corresponding to the clearance 148 between the tail plug 134 and the rotary cylinder 123, and the dimensions of each member vary. Even so, the outward projecting portion of the protrusion 131 can be reliably detached from the guide groove rear end portion 108 of the guide groove 107. For this reason, even if the cartridge body 110 is once immersed in the shaft tube 103 and then the tail plug 134 is further rotated counterclockwise, the projecting portion 131 projecting outward from the receiving tube 130 has an outward projecting portion. Since it is separated from the guide groove 107 of the inner wall surface 104 of the inner wall 104, it idles in synchronization with the rotation of the rotary cylinder 123. Accordingly, the receiving cylinder 130 integrated with the rotating cylinder 123 via the rotation fitting portion 146, the locking cylinder 138 integrated with the receiving cylinder 130 via the attachment / detachment fitting portion 147 and the rotation knurls 132, 140, All of the screw shaft 115 that is integrated with the rotation cylinder 123 through the rotation fitting portion 145 and the rotation cylinder 123, the engagement portion 124, and the engagement hole 118 is synchronized with the rotation of the tail plug 134. Will rotate together. Therefore, since the core chuck 112 that holds the bar-shaped cosmetic material 122 in the core tube 111 does not move backward with respect to the screw shaft 115, the bar-shaped cosmetic material that accompanies the immersion of the bar-shaped cosmetic material 122 into the core tube 111. 122 can be prevented from being damaged.

  The cartridge body 110 holding the bar-shaped cosmetic material 122 is replaced with the rotation cylinder 138 of the cartridge body 110 by first pulling the cartridge body 110 with the cartridge body 110 protruding most from the opening 103 ′ of the shaft cylinder 103. The engagement of the attachment / detachment fitting portion 147 with the receiving cylinder 130 and the rotation knurls 132 and 140 is dissociated, and the engagement portion 124 disposed at the tip of the rotating cylinder 123 in the shaft cylinder 103 and the screw shaft 115 in the cartridge body 110. When the engagement of the engagement hole 118 is dissociated, the cartridge body 110 can be taken out. Then, a new cartridge body 110 is inserted into the shaft cylinder 103, and the retaining cylinder 138 is received by the engagement of the attaching / detaching fitting portion 147 between the receiving cylinder 130 and the retaining cylinder 138 and the rotation knurls 132 and 140. The cylinder 130 is integrated, and the engagement hole 118 of the screw shaft 115 is engaged with the engagement portion 124 at the tip of the rotating cylinder 123 in the shaft cylinder 103 so that both are integrated.

  The present invention can be applied not only to a bar-shaped cosmetic material but also to a feeding container for an adhesive such as a bar-shaped paste.
