  The present invention has been made in order to solve such problems, and provides a filling extrusion container capable of improving hygiene, handling, improving usability and feeling of use, and protecting the filling. For the purpose.

The filling extruding container according to the present invention includes a main body, a tip cylinder mounted on the front end side of the main body so as to be relatively rotatable, and accommodated in the tip cylinder so as to form a cylinder and filled with a filling. The filling member that exposes the filling from the tip, the moving body that pushes the filling toward the tip of the filling member by advancing in the axial direction, and the main body and the front tube rotate relative to each other in the feeding direction / rewinding direction. Then, the screwing action works first, the filling member including the moving body is moved forward / backward, and the leading end portion of the filling member is caused to appear and disappear from the opening at the leading end of the leading tube, and when the filling member reaches the forward limit, the screwing is performed. When the main body and the front tube are further rotated relative to each other in the feeding direction in a state where the first screwing portion where the combined action stops and the filling member reaches the forward limit and the screwing action of the first screwed portion is stopped. A second screwing portion that has a screwing action and advances the moving body. , The body built with movably engaged with the main body and the synchronous rotatable and axially rotational member moving body and the synchronous rotatable and to axially movably engaged, acts as a detent of the movable body The rotating member is characterized by advancing and retreating at least a predetermined amount as the filling member including the moving body advances and retreats by the screwing action of the first screwing portion .

  According to such a filling extrusion container, the front tube is attached to the front end side of the main body so as to be relatively rotatable, and the filling member is filled inside the front tube and exposes the filling material from the front end portion. When the main body and the front cylinder are relatively rotated in the pay-out direction, the first screwing portion is first screwed, and the filling member including the moving body moves forward to advance the tip portion of the filling member. Appears from the opening at the tip of the front tube, and when the filling member is extended to the use position which is the forward limit, the screwing action of the first screwing portion stops, and the main body and the front tube rotate relative to each other in the supply direction. Then, the screwing action of the second screwing part works, this time the moving body moves forward, the filling material in the filling member is exposed from the tip part of the filling member, and is put into use. And the first tube are rotated relative to each other in the rewinding direction, the screwing action of the first screwing portion works first. Tip of the filling member filler member comprising a moving body is moved backward is returned repeatedly to the accommodated position within the immersive and destination cylinder from the opening of the tip of the leading tube. In this way, for example, the tip of the filling member that comes into contact with the part to be coated such as the skin emerges from the front tube during use and is immersed and accommodated in the front tube after use. For this reason, improvement of hygiene, protection by the front end of the filling and protection by the filling member of the filling are achieved, and after use, the overall length is shortened and compacted, while the use is made to be an appropriate overall length during use. In addition, the usability (ease of use) is improved, and in addition, it can be used in the same sense as a stick-shaped cosmetic container such as lipstick, and the usability is improved. In addition, since the rotating member built in the main body engages with the main body in a synchronously rotatable manner and with the moving body so as to be able to rotate in a synchronous manner, the rotating member functions as a detent of the moving body and functions as a detent of the moving body. Is engaged with the main body so as to be movable in the axial direction, and can be moved forward / backward according to the forward / backward movement of the filling member including the moving body by the screwing action of the first screwing portion. Since the body is engaged with the body so as to be movable in the axial direction, the moving body can be moved forward by the screwing action of the second screwing portion without any trouble. As described above, since the rotation member functioning as a detent for the moving body can be moved in the axial direction, the moving distance of the filling member including the moving body by the screwing action of the first screwing portion, The tip of the filling member that is extended to the use position can be extended as compared with the case where the detent of the moving body does not move in the axial direction because the moving distance of the moving body due to the screwing action of the second screwing portion Can be sufficiently exposed, and the amount of filler used can be increased.

  Here, as a configuration of the filling extrusion container that preferably exhibits the above-described operation, specifically, the rotating member includes a shaft body having a non-circular outer shape standing from the bottom of the rotating member, and moves. A configuration in which the inner surface of the body is configured to engage with the non-circular outer shape so as to be capable of synchronous rotation and axial movement is possible.

There is a configuration in which the second screwing portion is formed by screwing the female screw provided in the screw and the male screw provided on the outer surface of the moving body.

  Further, when the female screw member includes a locking portion that locks the rotating member in the axial direction, the rotating member is surely moved according to the movement of the filling member including the moving body by the screwing action of the first screwing portion. To move on.

  Here, the engaging portion of the female screw member has a configuration in which the female screw member is in the retreat limit and is spaced apart in the axial direction from the engaging portion of the rotating member. When the cylinder is relatively rotated in the feed-out direction, the screwing action of the first screwing portion works, the female screw member advances by a predetermined amount in the axial direction, and the locking portion of the female screw member moves the rotating member in the axial direction. When the main body and the front tube are further rotated relative to each other in the pay-out direction, the female screw member reliably moves forward by a predetermined amount in the axial direction along with the rotating member by the locking of the locking portion. Therefore, the length of the first screwing portion and the length of the second screwing portion can be ensured to the maximum, and the tip of the filling member fed out to the use position is sufficiently exposed and filled. It is possible to efficiently design the length in the axial direction, such as increasing the amount of objects used.

  As described above, according to the filler extrusion container according to the present invention, for example, the front end portion of the filling member that comes into contact with the coated portion such as the skin emerges from the front tube during use, and is immersed and accommodated in the front tube after use. Therefore, it is possible to improve the hygiene and protect the filling with the front tube and the filling with the filling member, and after use, the overall length is shortened to make it compact, while the appropriate overall length for use In addition, handling and usability (ease of use) can be improved, and in addition, for example, it can be used in the same sense as a stick-shaped cosmetic container such as lipstick, and the usability can be improved. In addition, it is possible to sufficiently expose the front end of the filling member that is fed out to the use position, and to increase the amount of the filler used.

A long hole 5d that extends a predetermined length in the circumferential direction is connected to the base of the slit 5n. The functions of these slits 5n and long holes 5d will be described later.

  As shown in FIG. 28, the inner diameter of the outer diameter small diameter portion 5a of the female screw member 5 is made smaller than the inner diameter of the outer diameter large diameter portion 5b. A female screw 5j constituting the other of the two screwing portions (screwing mechanism) 9 is provided so as to form a semicircular arc shape across the slits 5n and 5n.

  Further, as shown in FIGS. 26 and 28, the female screw member 5 has an O-ring (elastic body) shown in FIG. 2 on the outer peripheral surface on the distal end side of the outer diameter small diameter portion 5a which is the outer peripheral side of the female screw 5j. A groove 5m for mounting 11 is formed so as to form a semicircular arc shape along the circumferential direction so as to cross the slits 5n, 5n.

  The female screw 5j of the female screw member 5 having such a configuration is formed by a core pin (molding die) having a screw portion forming the female screw 5j on the outer peripheral surface. This core pin is so-called forced removal that is pulled out to the front end side in the axial direction after the resin is cured during resin molding. During this forced removal, the outer diameter small diameter portion 5a of the female screw member 5 is reduced in diameter by the slits 5n and 5n. It opens outward in the direction, and the core pin can be easily pulled out without damaging the female screw 5j. Further, when the outer diameter small diameter portion 5a opens radially outward, the stress acting on the root portions of the slits 5n, 5n is dispersed by the long holes 5d, 5d, and the female screw member 5 is prevented from being damaged. ing. As described above, the female screw member 5 has a configuration that allows the core pin to be forcibly removed without rotating the core pin, so that it can be quickly formed and the manufacturing cost can be reduced.

In addition, the rear end surface of the flange portion 5c is abutted against the front end surface of the main body portion 16x (convex portion 16d) of the rotating member 16, and the screw projection 5e is screwed into the screw groove 3b of the front tube 3. It is said that. In this state (in a state where the female screw member 5 is in the retreat limit), the annular protrusion (locking portion) 5k of the female screw member 5 is rearward in the axial direction with respect to the convex portion 16d (locking portion) of the rotating member 16. And is not engaged with the convex portion 16d.

  Further, an O-ring 11 is fitted in the groove 5m of the female screw member 5, and the outer diameter small diameter portion 5a of the female screw member 5 that is split by the slits 5n, 5n is tightened by the elastic force of the O-ring 11. As a result, the operating resistance of the second screwing portion 9 constituted by the female screw 5j of the female screw member 5 and the male screw 6b of the moving body 6 is increased, and the screwing protrusion 5e of the female screw member 5 and the leading tube are increased. The operating resistance of the first screwing portion 8 constituted by the three screwing grooves 3b is set higher.

  Although the O-ring 11 is used here, for example, a C-ring or the like may be used as another ring-shaped elastic body. Further, if the male screw 6b of the moving body 6 is inserted into the female screw 5j of the female screw member 5, the female screw 5j and the slit 5n can be engaged with each other if the inner diameter of the female screw 5j is expanded by the slit 5n. The outer diameter and small diameter portion 5a having the above becomes an elastic portion for applying an elastic force to the second screwing portion 9, and in this case, there may be no ring-shaped elastic body.

  From the first screwing portion 8 constituted by the screwing protrusion 5e of the female screw member 5 and the screwing groove 3b of the front tube 3, the female screw 5j of the female screw member 5, and the male screw 6b of the moving body 6. As shown in FIGS. 21 and 28, the lead of the first screwing portion 8 is larger than the lead of the second screwing portion 9 in the configured second screwing portion 9. ing. Here, the lead is a distance that advances in the axial direction when the screw is rotated once.

  And the extrusion mechanism provided with the rotation prevention part 50 comprised from such 1st, 2nd screwing parts 8 and 9, the protrusion 6d of the moving body 6, and the protrusion 16e of the shaft 16y of the rotating member 16, The female screw member 5, the moving body 6, the piston 7, and the rotating member 16 are built in a main body side cylinder including the main body cylinder 1, the front cylinder holding member 2, and the front cylinder 3 to constitute a main body side assembly 40 ( (See FIG. 33).

  As shown in FIG. 2, the filling member 4 is for filling the filling region 4x with the filling material L, and for discharging the filling material L from the tip according to the operation by the user. is there. The material of the filling member 4 is preferably an injection-molded plastic such as polyethylene terephthalate (PET) or polypropylene (PP). A transparent material or a filling material L can be used so that the color tone or filling state of the filling material L can be confirmed. It is preferable to use a coloring material having the following colors.

  As shown in FIGS. 30 to 32, the filling member 4 has a cylindrical shape and a shape whose tip is tapered and closed, and an outer surface 4a of the tip is an inclined surface inclined in a predetermined direction. ing. Further, as shown in FIG. 32, an inner surface 4b is formed on the back surface of the outer surface 4a at the front end portion of the filling member 4 and is inclined with a certain thickness from the outer surface 4a. In addition, a discharge port 4c that communicates the inner surface 4b and the outer surface 4a is provided. As shown in FIGS. 30 and 31, three discharge ports 4c are provided in this embodiment. And the outer surface 4a which the front-end | tip part inclines is made into the application part for apply | coating the filler L discharged through the discharge outlet 4c to a to-be-coated part. The outer surface 4a as the application part is an inclined surface suitable for application to an application part such as a skin. The number of discharge ports 4c may be one or a plurality other than three.

  Further, as shown in FIG. 32, on the inner peripheral surface of the rear end portion of the filling member 4, an annular concavo-convex portion 4 g that is concavo-convex in the axial direction and extends annularly along the circumferential direction is formed in the annular convex-concave portion of the female screw member 5. 5g is provided to engage in the axial direction. Further, in the vicinity of the front side of the annular concavo-convex portion 4g on the inner peripheral surface of the filling member 4, a knurl 4e extending over a predetermined length toward the distal end side in the axial direction and having concavo-convex portions closely arranged along the circumferential direction, It is provided to engage with the protrusion 5f of the female screw member 5 in the rotational direction. The rear end portion of the convex portion constituting the knurl 4e is configured as an inclined portion that is inclined in one direction so as to be easily engaged with the protrusion 5f of the female screw member 5.

  The knurls 4e of the filling member 4 and the ridges 5f of the female screw member 5 are inclined in such a manner that the rotating member 16, the movable body 6 and the female screw member 5 are positioned at the retreat limit shown in FIG. When the filling member 4 is incorporated into the female screw member 5 without rotating further in the rewinding direction, the knurl 4e of the filling member 4 abuts on the protrusion 5f of the female screw member 5 and follows the inclination of the knurl 4e. The screw member 5 is slightly rotated in the feed-out direction, and is inclined to facilitate the engagement between the knurl 4e and the protrusion 5f (details will be described later).

  As shown in FIGS. 30 to 32, the filling member 4 further includes an outer peripheral step surface 4 h on the outer peripheral surface in the middle of the axial direction for extrapolating a later-described assembly jig from the front end side. Yes.

  As shown in FIG. 2, the filling member 4 is inserted into the front tube 3, and a rear portion thereof is externally inserted into the female screw member 5, and the annular concavo-convex portion 4 g is formed into an annular convex recess 5 g of the female screw member 5. And the protrusion 5f of the female screw member 5 is engaged with the knurled member 4e in the rotational direction, so that the female screw member 5 can be synchronously rotated and cannot be detached from the axial direction. It is integrated with the screw member 5 and accommodated in the front tube 3 in this state. The cap 10 is detachably engaged with the protrusion 2e of the front tube pressing member 2 so that the front tube 3 containing the filling member 4 is covered and protected.

  When assembling the filling extrusion container 100 having such a configuration, the moving body 6 is screwed into the female screw member 5, the O-ring 11 is then attached to the female screw member 5, and the shaft of the rotating member 16 is then mounted. While the body 16y is engaged with the moving body 6, the convex portion 16d of the rotating member 16 is engaged with the annular protrusion 5k of the female screw member 6, and then the piston 7 is attached to the moving body 6, and then the front cylinder presser The female screw member 5 assembled earlier is screwed into the front tube 3 on which the member 2 is extrapolated, and then the main body tube 1 is rotated around the concavo-convex portion 16b of the rotating member 16 and the protrusion 1f of the main body tube 1. The main body side assembly 40 shown in FIG. 33 is obtained by attaching to the front tube pressing member 2 assembled earlier while engaging in the direction.

  Here, in order to attach the rotating member 16 to the movable body 6 and the female screw member 5, the body portion 16 x of the rotating member 16 is externally inserted into the outer diameter large diameter portion 5 b of the female screw member 5. The annular protrusion 5k of the outer diameter large diameter portion 5b of the rotating member 16 abuts against the convex portion 16d of the main body portion 16x of the rotating member 16, but the distal end side of the rotating member 16 is radially outward due to the slit 16c (see FIG. 14) of the rotating member 16. The annular protrusion 5k of the female screw member 5 enters the rear side beyond the convex portion 16d of the rotating member 16, and can be easily assembled. In addition, after the main assembly 40 is obtained, the outer peripheral surface on the front end side of the rotating member 16 is regulated close to the inner peripheral surface of the rear end portion of the front tube 3, so that the front end of the rotating member 16 is The side does not open outward in the radial direction, and it is possible to perform the operation described later without any hindrance when the annular protrusion 5k of the female screw member 5 and the convex portion 16d of the rotating member 16 are locked in the axial direction. Yes.

  On the other hand, as shown in FIG. 33, the filling member 4 is filled with a predetermined amount of the filling material L in the filling region 4x while the discharge port 4c is closed with the seal 12 and turned upside down. There is no space in the tip. Then, the filling member 4 filled with the filler L is inserted into the distal end side of the main assembly 40 and attached to the female screw member 5.

  Here, an example of specific assembly of the filling member 4 and the main assembly 40 will be described. As shown in FIG. 34, the cylindrical standing portion 13a of the lower jig 13 is inserted into the front tube 3. At the same time, it is extrapolated to the filling member 4 and the upper end surface of the cylindrical standing portion 13a is brought into contact with the outer peripheral step surface 4h of the filling member 4, and the lower end surface of the upper jig 14 is brought into contact with the rear end surface of the main body cylinder 1. The upper jig 14 is lowered or the lower jig 13 is raised. Then, the annular concavo-convex portion 4g of the filling member 4 is engaged with the annular convex recess 5g of the female screw member 5 in the axial direction, and the protrusion 5f of the female screw member 5 is engaged with the knurl 4e of the filling member 4 in the rotational direction. In combination, the female screw member 5 and the filling member 4 are integrated.

  At this time, the inner circumferential surface of the filling member 4 is engaged with the female screw member 5 while being in sliding contact with the annular protrusion 7 c for ensuring the watertightness of the piston 7. Further, as described above, since the inclination of the knurl 4e of the filling member 4 and the protrusion 5f of the female screw member 5 are inclined so that the female screw member 5 rotates in the feeding direction, the filling member 4 becomes the female screw member 5. Easy to install. Note that an air vent groove extending in the axial direction so as to cross the annular protrusion 7c of the piston 7 is provided on the inner peripheral surface of the filling member 4, and when the filling member 4 is mounted, air on the filling L side is supplied. You may make it extract to the back side via an air vent groove.

  Then, if the jigs 13 and 14 are removed and the seal 12 is finally peeled off, an initial state of the filler extruding container 100 shown in FIG. 2 is obtained. The seal 12 is hygienic when peeled off after purchase by a user (consumer). In the initial state of the filler extruding container 100, the filling member 4 is accommodated in the front tube 3, and the rear end surface of the rotating member 16 is in contact with the bottom surface of the main body tube 1.

  According to the filler extrusion container 100 configured as described above, as shown in FIG. 33, the filling member 4 filled with the filler L is inserted and attached to the distal end side of the main assembly 40. Therefore, it is easy to assemble the filling member 4 after filling the filling member 4 into the filling member 4, and this filling member L is a filling region 4 x between the inside of the front end of the filling member 4 and the piston 7 of the main assembly 40. In addition, it is fully (full) filled.

  1, when the cap 10 is removed by the user and the main body cylinder 1 and the front cylinder 3 are rotated relative to each other in the feeding direction, the second screw is inserted. Since the operating resistance of the joint portion 9 is higher than the operating resistance of the first screwing portion 8, the screwing action of the first screwing portion 8 operates.

  When the relative rotation in the extending direction is continued, the rotation preventing portion 50 constituted by the protrusion 16e of the shaft body 16y of the rotating member 16 and the protrusion 6d of the movable body 6 which are engaged with the main body cylinder 1 so as to be synchronously rotatable. As a result of this cooperation, the moving body 6 and the piston 7 move forward together with the female screw member 5 and the filling member 4, and the distal end portion 4 a of the filling member 4 having the discharge port 4 c appears from the opening at the distal end of the front tube 3.

  When the female screw member 5 advances by a predetermined amount, specifically, the axial protrusion distance between the annular protrusion 5k of the female screw member 5 and the convex portion 16d of the rotating member 16, the annular protrusion of the female screw member 5 is increased. When the portion 5k locks the convex portion 16d of the rotating member 16 in the axial direction, and then the main body tube 1 and the front tube 3 are relatively rotated in the feed-out direction, the annular protrusion 5k and the convex portion 16d are locked. As a result, the female screw member 5 moves forward with the rotating member 16 and the amount of protrusion of the front end portion 4a of the filling member 4 from the front tube 3 increases. As shown in FIG. The screw projection 5e advances to the forward limit located at the tip 3f of the screw groove 3b of the front tube 3. At this time, the front surface of the concavo-convex portion 16b of the rotating member 16 is in contact with the rear end surface of the flange portion 3a of the front tube 3, or is positioned in the vicinity of the rear end surface of the flange portion 3a.

  When the filling member 4 (female screw member 5) moves forward, the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9, so that the filling member 4 is The use position which is the forward limit is quickly reached according to the large lead of the first screwing portion 8. Then, when the screw projection 5e of the female screw member 5 reaches the tip 3f of the screw groove 3b of the front tube 3, the advancement is blocked, and the screwing action of the first screwing portion 8 is stopped.

  Subsequently, when the main body cylinder 1 and the front cylinder 3 are relatively rotated in the feeding direction, since the screwing action of the first screwing part 8 is stopped, the screwing action of the second screwing part 9 is stopped. The movable body 6 and the piston 7 move forward as shown in FIG.

  At this time, since the lead of the second screwing portion 9 is made smaller than the lead of the first screwing portion 8, the piston 7 is slowly extended according to the small lead of the second screwing portion 9. The filling material L is appropriately discharged from the discharge port 4c of the filling member 4 and put into use.

  Further, as described above, since the filling material L is sufficiently filled in the filling region 4x between the inside of the tip of the filling member 4 and the piston 7, the relative rotation is repeated more than necessary. As shown in FIG. 4, the filling L is discharged from the discharge port 4c promptly (immediately).

  When the main body cylinder 1 and the front cylinder 3 are rotated relative to each other in the retraction direction (the direction opposite to the extension direction) after use, as described above, compared to the operating resistance of the first screwing portion 8. Since the operating resistance of the second screwing portion 9 is increased, the screwing action of the first screwing portion 8 works first, and as shown in FIG. The moving body 6 and the piston 7 are retracted together with the female screw member 5 and the filling member 4. At this time, the rotating member 16 may be retracted together with the female screw member 5 by its own weight, or may be brought into contact with the flange portion 5c of the retracting female screw member 5 and retracted by the flange portion 5c.

  Then, as the filling member 4 moves backward, the front end portion 4a of the filling member 4 having the discharge port 4c is immersed from the opening at the front end of the front tube 3 (see FIG. 6), and the rear end surface of the rotating member 16 is While contacting the bottom surface, the rear end surface of the flange portion 5c of the female screw member 5 contacts the front end surface of the main body portion 16x (convex portion 16d) of the rotating member 16, and the filling member 4 reaches the retreat limit.

  When the filling member 4 is retracted, the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9. It is quickly rewound according to the large lead of section 8. When the filling member 4 reaches the retreat limit, further retreat of the screw projection 5e of the female screw member 5 is prevented, and the screwing action of the first screwing portion 8 is stopped.

  Here, when the main body cylinder 1 and the front cylinder 3 are further rotated relative to each other in the retraction direction, the screwing action of the first screwing part 8 is stopped, so that the screwing of the second screwing part 9 is stopped. The combined action works, and the movable body 6 and the piston 7 retreat as shown in FIG.

  At this time, due to the retraction of the piston 7, the filling material L is sucked into the filling region 4 x from the discharge port 4 c of the filling member 4, and a predetermined space A is formed inside the discharge port 4 c of the filling member 4. Therefore, the filling L remaining on the outer surface 4a of the front end portion of the filling member 4 is reduced and economical, and the filling L filled in the filling region 4x and the air mixed in the filling L are subject to temperature changes and Even if it expands due to a change in atmospheric pressure, leakage of the filling material L from the discharge port 4c is prevented by the predetermined space A provided inside the discharge port 4c.

  Then, due to the relative rotation of the main body cylinder 1 and the front cylinder 3 in the retraction direction, the movable body 6 is retracted to the retreat limit, and the relative rotational force for further retreating to the movable body 6 at the maximum retreat position is generated. Further, when applied by the user, when there is no shaft body twisting prevention mechanism constituted by the groove 6f of the moving body 6 and the protrusion 16g of the rotating member 16, the rear end surface of the moving body 6 and the rotating member 16 are provided. There is a possibility that the shaft body 16y of the rotating member 16 that is in pressure contact with the bottom surface of the rotating member 16 and engages with the moving body 6 in the rotational direction may be twisted at the bottom surface of the rotating member 16.

  However, in the present embodiment, when the moving body 6 is retracted to the retreat limit, the groove 6f of the moving body 6 enters the protrusion 16g of the rotating member 16 and engages in the rotation direction. Even if the cylinder 1 and the front cylinder 3 are further rotated relative to each other in the retraction direction, the rotational force that further moves the moving body 6 acting on the shaft body 16y rotates through the groove 6f of the moving body 6. The protrusion 16g of the member 16 is also given and dispersed to prevent the shaft body 16y from being twisted.

  In addition, it is good also as a structure which provides a recessed part instead of the groove | channel 6f of the moving body 6 for preventing torsion of the shaft body 16y, and the said recessed part engages with the protrusion part 16g of the rotating member 16 in the rotation direction. As another example of the shaft body torsion prevention mechanism, conversely to the above-described shaft body torsion prevention mechanism, a plurality of protrusions protruding rearward are provided on the rear end surface of the moving body 6 along the circumferential direction, and rotated. A plurality of recesses may be provided on the bottom surface of the member 16 on the periphery of the shaft body 16y so that the protrusions of the moving body 6 enter and engage in the rotational direction when the moving body 6 is fully retracted.

  As shown in FIG. 6, when the filling material L remains in the filling member 4x, the main body tube 1 and the front tube 3 are again drawn out by the user in order to put the filling material L into a use state. And thereafter, the same operation as described above is performed, and such an operation is repeated.

  Further, as shown in FIG. 7, when the piston 7 moves forward to the maximum by the relative rotation of the main body cylinder 1 and the leading cylinder 3, the piston 7 comes into contact with the inner surface 4 b of the front end portion of the filling member 4. The filling L in the filling area 4x is almost used up.

  When the filling L is almost used up and the main body cylinder 1 and the front cylinder 3 are rotated relative to each other in the retraction direction from the state shown in FIG. The front end 4a of the filling member 4 having 4c is immersed from the opening at the front end of the front tube 3, and is in the state shown in FIG.

  As described above, according to the filler extruding container 100 of the present embodiment, when the main body cylinder 1 and the front cylinder 3 are relatively rotated in the feeding direction, the screwing action of the first screwing portion 8 works first. When the filling member 4 including the moving body 6 moves forward, the leading end 4a of the filling member 4 emerges from the front tube 3, and when the filling member 4 reaches the advance limit, the screwing action of the first screwing portion 8 stops. When the main body cylinder 1 and the front cylinder 3 are further rotated relative to each other in the extending direction in a state where the screwing action is stopped, the screwing action of the second screwing portion 9 is activated, and the moving body 6 moves forward. Then, when the filling L is put into a use state and the main body cylinder 1 and the front cylinder 3 are relatively rotated in the retraction direction after use, the screwing action of the first screwing portion 8 works first, and the moving body 6 The filling member 4 including the back is retracted and the tip portion 4a of the filling member 4 is immersed in the front tube 3 and is returned to a predetermined position. The tip 4a of the filling member 4 that comes into contact with the portion or the like emerges from the front tube 3 during use and is immersed and accommodated in the front tube 3 after use. Protection and protection by the filling member 4 of the filling material L are achieved, and after use, the overall length is shortened and compacted, while at the time of use, the overall length is moderate and handling and usability (ease of use) are improved. In addition, for example, it can be used in the same sense as a stick-shaped cosmetic container such as lipstick, and the usability is improved.

  Further, since the rotating member 16 built in the main body cylinder 1 and functioning as a detent for the moving body 6 is engaged with the main body cylinder 1 so as to be movable in the axial direction, the moving body by the screwing action of the first screwing portion 8 is engaged. 6 can be moved forward / backward according to the forward / backward movement of the filling member 4 including 6, and the rotating member 16 is engaged with the movable body 6 so as to be movable in the axial direction. The moving body 6 can be moved forward / backward without any hindrance, and thus the rotation member 16 functioning as a detent for the moving body 6 can be moved in the axial direction. The moving distance of the filling member 4 including the moving body 6 due to the screwing action of the joint portion 8 and the moving distance of the moving body 6 due to the screwing action of the second screwing portion 9 are determined so that the rotation stop of the moving body 6 is the axial direction. It is possible to extend compared to the case where it does not move, and it is drawn out to the use position Hama and to sufficiently expose the distal portion 4a of the member 4, and is it possible to increase the amount of filler L.

  In particular, in the present embodiment, in a state where the female screw member 5 is in the retreat limit, the annular protrusion 5k that is the locking portion of the female screw member 5 is opposed to the convex portion 16d that is the locking portion of the rotating member 16. In this state, when the main body tube 1 and the front tube 3 are relatively rotated in the feeding direction, the screwing action of the first screwing portion 8 works and the female screw member 5 is When the rotary member 16 is locked in the axial direction after a predetermined amount of advance in the axial direction, and the main body cylinder 1 and the leading cylinder 3 are further rotated relative to each other in the extending direction, the female screw member 5 is locked to the locking portions 5k, 16d. As a result of the engagement, the rotation member 16 moves forward by a predetermined amount in the axial direction. Therefore, the axial lengths of the convex and concave portions 1a of the main body cylinder 1 and the concave and convex portions 2b of the front cylinder pressing member 2 that are the engaging portions between the main body cylinder 1 and the front cylinder pressing member 2 and the spring portions 2d of the front cylinder pressing member 2 are provided. The length of the first screwing portion 8 and the length of the second screwing portion 9 can be maximized while sufficiently securing the axial length. For this reason, it is possible to efficiently design the length in the axial direction, for example, it is possible to sufficiently expose the tip portion 4a of the filling member 4 drawn out to the use position and increase the amount of the filling L used. It is said that.

  Further, as described above, the female screw member 5 includes the annular protrusion 5k that locks the rotating member 16 in the axial direction, and thus includes the moving body 6 by the screwing action of the first screwing portion 8. As the member 4 moves, the rotating member 16 moves reliably. In addition, for example, the shape of the distal end portion 4a of the filling member 4 that comes into contact with the application portion such as the skin can be selected as an arbitrary shape that can be easily applied, and the usability can be further improved.

  In particular, assuming that the length in the axial direction can be efficiently designed, the female screw member 5 moves forward by a predetermined amount from the retreat limit with the rotation member 16 functioning as a detent being left, and then the rotation member 16 is attached. However, it is also possible to adopt a configuration in which, for example, the engaging portions are moved forward together with the rotating member 16 by, for example, abutting the locking portions in the axial direction in advance.

  Moreover, according to the filling material extrusion container 100 of this embodiment, there exist the following effects. In other words, the front tube holding member 2 including a spring portion 2 d that is accommodated in the main body tube 1 and can be expanded and contracted in the axial direction is provided, and the front tube 3 is urged rearward by the spring portion 2 d of the front tube holding member 2. Since it is rotatably mounted on the main body cylinder 1 via the front cylinder pressing member 2 in a state where the main body cylinder 1 and the front cylinder 3 are rotated relative to each other by the spring portion 2d of the front cylinder pressing member 2, In addition, an external force such as impact or vibration acting due to, for example, dropping of the container 100 is buffered to prevent leakage of the filling material L from the discharge port 4c and to prevent destruction of the member.

  In addition, since the lead of the first threaded portion 8 is made larger than the lead of the second threaded portion 9, the first rotation of the main body tube 1 and the leading tube 3 causes the first rotation. The filling member 4 in which the screwing action of the screwing portion 8 of this type works is quickly drawn out to the use position according to the large lead, and the tip end portion 4a of the filling member 4 emerges from the inside of the front tube 3, and the further main body tube 1 and the front tube 3, the moving body 6 in which the screwing action of the second screwing portion 9 works is slowly drawn out according to a small lead, and the filling material L is appropriately fed to the tip portion 4 a of the filling member 4. After being used, it is discharged from the discharge port 4c, and after use, the filling member 4 is quickly returned according to the large lead by the relative rotation of the main body tube 1 and the front tube 3 in the rewinding direction. 4 is inserted into the front tube 3 and retracted to the storage position. Result, usability (ease of use) are further improved.

  In the present embodiment, the operating resistance of the second screwing portion 9 is increased by using the elastic force of the elastic portion (O-ring 11). As another configuration for increasing the operating resistance, for example, , Different materials, different contact resistances of screws, and the like. Moreover, as another structure which raises the operating resistance of the 2nd screwing part 9, the structure by the sliding resistance of the axial direction of the piston 7 is also mentioned, for example.

  Further, in the present embodiment, the operating resistance of the first screwing portion 8 is ensured so that the screwing action of the first screwing portion 8 works before the screwing action of the second screwing portion 9. The operating resistance of the second screwing portion 9 is increased as compared with that of the first screwing portion 8 as compared with the lead of the second screwing portion 9 as in this embodiment. If the lead is made larger, the screwing action of the first screwing part 8 will work before the screwing action of the second screwing part 9.

  In addition, by increasing the lead of the first screwing portion 8 as compared with the lead of the second screwing portion 9 in this manner, the filling member 4 can be quickly moved in and out of the front tube 3, while the piston 7 The filling member 4 is discharged moderately slowly so that the filling member 4 moves faster than the piston 7, but the lead of the first screwing portion 8 and the lead of the second screwing portion 9 are the same. It is also possible to make the moving speeds of the filling member 4 and the piston 7 the same. In this case, as described above, the screwing of the first screwing portion 8 is increased as in the configuration in which the working resistance of the second screwing portion 9 is increased compared to the working resistance of the first screwing portion 8. It is necessary to adopt a configuration in which the combined action works before the screwed action of the second screwed portion 9. If the lead of the first screwing portion 8 is made smaller than the lead of the second screwing portion 9, the piston 7 can be moved faster than the filling member 4.

  Incidentally, a porous material such as foamed urethane or a fine net-like material may be provided on the tip end (outer surface) 4a of the filling member 4 as an application portion, and fine hair or the like is provided on the outer surface 4a and applied. It is also possible to attach a brush formed by bundling a tapered taper-processed polyester fiber, and this may be used as an application part, or an elastic body such as silicon rubber or thermoplastic elastomer may be used as the application part.

  35 is a perspective view showing another rotating member used in place of the rotating member in FIGS. 2 to 8, and FIG. 36 is a longitudinal perspective view of the rotating member shown in FIG.

  The rotating member 16Z is different from the rotating member 16 in that the main body portion 16x having the slit 16c is replaced with a bottomed cylindrical main body portion 16m having a pair of openings 16n and 16n at positions opposed to the peripheral wall. The arc-shaped convex part 16p which protrudes inside (axial center side) along the inner edge at the front end side of the opening 16n in 16m is provided as a locking part locked to the female screw member 5 in the axial direction. is there.

  Even when the rotating member 16Z configured as described above is used, the same operations and effects as those when the rotating member 16 is used are provided.

  FIG. 37 is a longitudinal sectional view showing an initial state of the filling material extruding container according to the second embodiment of the present invention, and FIG. 38 is a state when the filling member is advanced to the maximum by a user operation from the state shown in FIG. FIG. 39 is a vertical cross-sectional view when the filling member is advanced to the maximum by the user's operation from the state shown in FIG. 37, and then the mobile body is fully advanced. FIG. 40 is FIGS. It is a disassembled perspective view which shows the inside rotation member and a moving body.

  The difference between the filling extrusion container 200 of the second embodiment and the filling extrusion container 100 of the first embodiment is that the rotating member 216 in which the cylindrical shaft body 16y is replaced with the cylindrical body 216y is replaced with the rotating member 16. In addition to using the cylindrical moving body 6, a shaft-shaped moving body 206 is used, and in accordance with this change, a female screw member 205 in which a part of the structure of the female screw member 5 is changed is used. Other configurations are the same as those of the first embodiment.

  Specifically, the cylindrical body 216y of the rotating member 216 is generally formed in a bottomed cylindrical shape. As shown in FIG. 40, the outer diameter small diameter portion 216a on the front end side and the rear end of the outer diameter small diameter portion 216a are formed. It has a stepped cylindrical shape including a large outer diameter portion 216b.

In the case of a rod-shaped body such as a core, particularly preferred filler extrusion containers 300 and 400 will be described. As this rod-like body M, a relatively hard or very soft rod-like body is used, and a thick rod-like body having an outer diameter of 10 mm or more is preferable. It is also possible to use a rod-shaped body.

  FIG. 41 is a longitudinal sectional view showing an initial state of the filler extruding container according to the third embodiment of the present invention, and FIG. 42 is a state in which the filling member continuously advances from the state shown in FIG. It is a longitudinal cross-sectional view when a moving body moves forward and is in a use state.

  The difference between the filling extrusion container 300 of the third embodiment and the filling extrusion container 100 of the first embodiment is that a cylindrical pipe member 304 is used instead of the filling member 4 having a closed end and a discharge port 4c. In addition, the pipe member 304 is filled with the rod-like body M as a filling material, and the other configuration is the same as that of the first embodiment.

  Specifically, the pipe member 304 is configured in a large-diameter cylindrical shape, and accommodates therein a large-diameter columnar rod-like body M so as to be slidable in a close state. Even if this rod-shaped body M is filled in the pipe member 304 by injecting a molten rod-shaped body-forming material into the pipe member 304 and solidifying by cooling, the rod-shaped body manufactured in advance is added to the pipe member 304. It may be inserted and filled in a close state. In addition, when the pipe member 304 is filled by injecting a molten rod-shaped body forming material into the pipe member 304 and cooling and solidifying, the rod-shaped body heated and melted after assembling the filler extrusion container 300. The pipe member 304 is filled from the tip of the pipe member 304 and the tip is finished (prepared) after cooling, and the tip of the pipe member 304 before assembly is sealed, and the rod-shaped body heated and melted from the rear end is cooled and mounted on the container after cooling. And can be adopted.

  In the third embodiment, the tip of the pipe member 304 is inclined at a predetermined angle, and the tip of the cylindrical rod-like body M is flush with the inclined opening 304a of the tip. The surface is also inclined. Therefore, the front end surface of the rod-like body M is an inclined ellipsoid, and is a surface suitable for application to an application portion such as skin. Moreover, the structure from the outer periphery level | step difference surface 4h of the axial direction middle of the pipe member 304 to a rear end is the same as that of the filling member 4 of 1st embodiment.

  Moreover, it replaces with piston 7 of 1st embodiment, and piston 307 whose front end surface inclines similarly to the front end surface of the rod-shaped body M is used. The piston 307 is in close contact with the inner peripheral surface of the pipe member 304, and the piston 307 and the rod-like body M are in airtight contact with each other in the pipe member 304.

  According to the filler extrusion container 300 having such a configuration, when the user rotates the main body cylinder 1 and the front cylinder 3 relative to each other from the initial state shown in FIG. , And the movable body 6 and the piston 307 are advanced together with the female screw member 5 and the pipe member 304 by the cooperation with the rotation stopper 50, and the tip of the pipe member 304 is opened at the tip of the front tube 3. When the female screw member 5 moves forward by a predetermined amount, the annular protrusion 5k of the female screw member 5 locks the convex portion 16d of the rotating member 16 in the axial direction, and then the main body cylinder 1 and the front cylinder 3 are connected to each other. When the relative rotation is performed in the extending direction, the female screw member 5 moves forward with the rotating member 16 by the engagement of the annular protrusion 5k and the convex portion 16d, and the protruding amount of the tip end portion of the pipe member 304 from the front tube 3 The pipe member 304 of the female screw member 5 increases. When the mating protrusion 5e moves forward to the forward limit located at the tip 3f of the threading groove 3b of the front tube 3, and then the main body tube 1 and the front tube 3 are relatively rotated in the feeding direction, the second threaded portion As shown in FIG. 42, the moving body 6 and the piston 307 move forward, and the rod-shaped body M is pushed out by the piston 307, and the tip of the pipe member 304 is engaged. It emerges from and is put into use.

  When the main body cylinder 1 and the front cylinder 3 are relatively rotated in the retraction direction after use, the screwing action of the first screwing part 8 works, and the female screw member 5 is cooperated with the rotation preventing part 50. The moving body 6 and the piston 307 are moved backward together with the pipe member 304, the tip end portion of the pipe member 304 is immersed from the opening at the tip end of the front tube 3, and the rear end surface of the rotating member 16 is in contact with the bottom surface of the main body tube 1. When the female screw member 5 reaches the retreat limit and the main body tube 1 and the front tube 3 are relatively rotated in the retraction direction, the screwing action of the second screwing portion 9 works, and the rotation preventing portion 50 By the cooperation, the moving body 6 and the piston 307 are retracted.

  At this time, since the piston 307 and the rod-like body M are in airtight contact with each other in the pipe member 304, the rod-like body M moves backward together with the piston 307, and the tip of the rod-like body M has the tip tube 3 and the pipe member 304. Housed inside.

  Even in such a filler extrusion container 300 of the third embodiment, substantially the same effect as that of the first embodiment can be obtained.

It is a longitudinal cross-sectional view when a moving body moves forward and is in a use state.

  The difference between the filler extrusion container 400 of the fourth embodiment and the filler extrusion container 300 of the third embodiment is that, instead of the piston 307, the outer diameter of the rear end portion that is in sliding contact with the inner peripheral surface of the pipe member 404 is used. A piston 407 having a tip portion 407a having a smaller outer diameter is used, and the rod-like body M1 is also filled around the tip portion 407a of the piston 407.

  The rod-like body M1 is filled in the pipe member 404 by injecting a molten rod-like body-forming material into the pipe member 404 and solidifying by cooling. Accordingly, the piston 407 and the rod-like body M1 are in an airtight state in the pipe member 404.

  In this filling material extruding container 400, the tips of the pipe member 404 and the rod-like body M1 are not inclined as in the third embodiment.

  According to the filler extruding container 400 having such a configuration, the same action and effect as the filler extruding container 300 of the third embodiment are obtained, and in addition, a rod-like body is also provided around the front end portion 407a of the piston 407. Since M1 is filled, the air density in the pipe member 404 between the piston 407 and the rod-like body M1 is further increased as compared with the third embodiment, and the rod-like body M1 moves backward more reliably together with the piston 407. be able to.

  As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment. For example, the male screw and the female screw may function in the same manner as a screw thread, such as a group of protrusions arranged intermittently or a group of protrusions arranged spirally and intermittently. The mating protrusion may be a continuous screw thread.
