JP 2001-87033 A

  However, the stick-shaped cosmetic container having such a configuration has a problem in that, for example, when the impact or vibration is applied by dropping the container, the stick-shaped cosmetic is detached from the inner plate and pulled out of the container. .

  The present invention has been made to solve such a problem, and performs the feeding and unwinding of the rod-shaped object such as the rod-shaped cosmetic material without any trouble, and the external action due to the impact and vibration. An object of the present invention is to provide a rod-like product extrusion container capable of preventing the rod-like product from coming out of the container when the is added.

A rod-like material extrusion container according to the present invention includes a cylindrical filling member that is attached to a container and that is open at both ends, and a rod-like material that is loaded in the filling member, and is relative to the container front and the container front. When the rotatable container rear part is relatively rotated in one direction, the movable body disposed in the container moves forward, causing a rod-like object to appear from the opening at the front end of the container, and the container front part and the container rear part are In a rod-like product extrusion container in which the moving body moves backward when rotated in the other direction, which is the opposite direction of one direction, the container is in the shape of a piston that is located at the tip of the moving body and is in close contact with the filling member and slides. The rod-shaped object is a solid rod-shaped object that is loaded in close contact with the filling member, and is maintained in the bar shape in the state where it is drawn out and exposed from the opening at the tip of the container by the advance of the moving body. , includes a first engagement portion and a second screwed portion into the container, and the container front portion When the rear part of the container is relatively rotated in one direction, the screwing action of the first screwing part and the second screwing part works together to advance the moving body, and the screwing action of the first screwing part. When a predetermined amount works, the screwing of the first screwing part is released, and when the relative rotation is further performed in one direction, only the screwing action of the second screwing part works to move the moving body forward and move. By retracting the body, the sticking member is pulled back in the filling member by the suction action by the backward movement of the pushing portion while maintaining the close contact state between the pushing portion and the stick-like member in the filling member.

According to such a rod-like material extruding container, the extruding part is located at the tip of the moving body disposed in the container and moving forward or backward, and the extruding part is in close contact with the filling member and is loaded into the filling member. The stick-shaped object is closely attached in the filling member, and the extrusion part is configured in a piston shape so that the stick-like object and the filling member are in close contact with each other. While appearing from the opening, a suction action (an action to maintain adhesion) between the extruded part and the rod-shaped object works as the extruded part retreats, and the rod-shaped object is pulled back in the filling member, so that the rod-shaped object The unwinding and unwinding of objects are performed without any trouble. Also, when an external action is applied due to impact, vibration, etc., if it tries to leave between the extrusion part and the rod-shaped object, it will be in a reduced pressure state and the adhesion function will work, so the rod-shaped object will not leave the extrusion part The rod-like material is prevented from coming out of the container. In addition, as described above, since a rod-shaped object (for example, a soft material (for example, jelly-shaped material)) is in close contact with the filling member, even if the rod-shaped object is broken in the filling member, the broken portion is filled. It does not detach from the member and can continue to be used. Moreover, since the double helical structure is formed by the first and second screwing portions, the length of the rod-shaped object can be ensured while saving the axial length of the rod-shaped material extrusion container. Then, after the moving body quickly moves forward by a cooperative action of the first screwing part and the second screwing part and advances by a predetermined amount, it slowly moves forward by the screwing action of only the second screwing part. Therefore, there is no possibility that the rod-shaped object is accidentally over-exposed.

The rod-like product extrusion container according to the present invention includes a cylindrical filling member that is attached to the container and that is open at both ends, and a rod-like material that is loaded on the filling member, and includes a container front part and the container front part. When the container rear portion that is relatively rotatable is rotated in one direction, the moving body disposed in the container moves forward, causing a rod-like object to appear from the opening at the tip of the container, and the container front portion and the container rear portion In the rod-like product extrusion container in which the moving body moves backward when the two are rotated relative to each other in the opposite direction of the one direction, the container is located at the tip of the moving body and slides in close contact with the filling member. A solid rod-shaped object that is provided with a piston-like extruding part, and that the rod-shaped object is closely packed in the filling member and is maintained in a state where the rod is drawn and exposed from the opening at the tip of the container by the advance of the moving body. , and the comprises a first engagement portion and a second screwed portion into the container, the container When the part and the container rear part are rotated relative to each other in the other direction, the screwing action of the first screwing part and the second screwing part work together to move the moving body backward, and the screwing of the first screwing part is performed. When the combined action works for a predetermined amount, the screwing of the first screwing part is released, and when the relative rotation is further made in the other direction, only the screwing action of the second screwing part works and the moving body moves backward. By moving the moving body backward, the sticking portion is pulled back in the filling member by the suction action by the backward movement of the pushing portion while the extruding portion and the rod-like object are kept in close contact with each other in the filling member. .

According to such a rod-like material extruding container, the extruding part is located at the tip of the moving body disposed in the container and moving forward or backward, and the extruding part is in close contact with the filling member and is loaded into the filling member. The stick-shaped object is closely attached in the filling member, and the extrusion part is configured in a piston shape so that the stick-like object and the filling member are in close contact with each other. While appearing from the opening, a suction action (an action to maintain adhesion) between the extruded part and the rod-shaped object works as the extruded part retreats, and the rod-shaped object is pulled back in the filling member, so that the rod-shaped object The unwinding and unwinding of objects are performed without any trouble. Also, when an external action is applied due to impact, vibration, etc., if it tries to leave between the extrusion part and the rod-shaped object, it will be in a reduced pressure state and the adhesion function will work, so the rod-shaped object will not leave the extrusion part The rod-like material is prevented from coming out of the container. In addition, as described above, since a rod-shaped object (for example, a soft material (for example, jelly-shaped material)) is in close contact with the filling member, even if the rod-shaped object is broken in the filling member, the broken portion is filled. It does not detach from the member and can continue to be used. Moreover, since the double helical structure is formed by the first and second screwing portions, the length of the rod-shaped object can be ensured while saving the axial length of the rod-shaped material extrusion container. Then, the moving body is quickly retracted by the cooperative action of the first screwing part and the second screwing part, and after being retracted by a predetermined amount, it is slowly retracted by the screwing action of only the second screwing part. Is possible.

  Further, it is preferable that a rod-shaped object is loaded on the filling member, and the filling member loaded with the rod-shaped object is attached to the container. When such a configuration is adopted, since the rod-shaped object is loaded only in the cylindrical filling member having both ends opened, the thickness of the filling member is relatively uniform and the radial thickness of the rod-shaped object is the axial direction. The temperature condition from when the molten rod-shaped material is charged to when it is solidified can be stabilized, and as a result, good loading of the rod-shaped material is possible and the production yield is improved. Moreover, since the filling member loaded with the rod-like object is mounted on the container, the manufacturing is facilitated.

  Moreover, the structure which charges a rod-shaped object to the filling member with which the container was mounted | worn is also preferable. When such a configuration is adopted, as in the above case, since the rod-shaped object is loaded only on the cylindrical filling member having both ends opened, it is possible to satisfactorily load the rod-shaped object and improve the manufacturing yield. At the same time, manufacturing is further facilitated due to the configuration in which the rod-shaped material is loaded into the filling member mounted on the container.

  The filling member is preferably made of a transparent material. When such a configuration is adopted, the state of the rod-shaped object loaded on the filling member can be confirmed from the outside.

  As described above, according to the present invention, the rod-like object is drawn out and returned without hindrance, and when an external action is applied due to impact or vibration, the rod-like object is prevented from coming out of the container, and It becomes possible to continue using the broken rod-shaped object. In addition, it is possible to use a particularly soft rod-shaped material that cannot be maintained by a normal rod-shaped material.

On the inner peripheral surface on the front side of the annular concavo-convex portion 1b, a large number of concavo-convex portions are arranged side by side in the circumferential direction, and the knurl 1c in which the concavo-convex portion extends in a predetermined length in the axial direction rotates in the protrusion 10e of the rotating member 10 It is provided to be engaged with.

  As shown in FIG. 1, the filling member 1 is inserted between the rotating member 10 and the piston 7 and the intermediate member 11 from the rear side, and the rear end surface is in contact with the flange portion 10 c of the rotating member 10, The portion 1b is engaged with the annular convex recess 10d of the rotating member 10 in the axial direction, and the protrusion 10e of the rotating member 10 is engaged with the knurling 1c in the rotating direction. It is mounted so that it cannot be detached, and is integrated with the rotating member 10. As described above, the rotating member 10 is prevented from detaching to the front side in the axial direction by the spring portion 11y of the intermediate member 11 integrated with the main body cylinder 3, and can be rotated synchronously with the moving screw cylinder 5. The moving screw cylinder 5 is screwed to the moving body 6 via the second screwing portion 9, and since the moving body 6 can be rotated synchronously with the main body cylinder 3, the filling member 1 has a main body. The cylinder 3 is mounted so that it can rotate and cannot be detached in the axial direction. Further, a piston 7 (annular protrusion 7 c) is inserted into the rear end portion of the filling member 1 so as to be in close contact with the filling member 1.

  As shown in FIG. 1, the filling member 1 is protected by the cap 12 by the cap 12 being detachably attached to the intermediate member 11.

  Next, an example of the manufacturing procedure of the rod-shaped product extrusion container 100 having such a configuration will be described with reference to FIG. First, the moving screw cylinder 5 is screwed into the moving body 6 to the initial position. Alternatively, it is forced to get over the thread and push it to the initial position. Next, the rotating member 10 is extrapolated to the moving screw cylinder 5 so that the protrusion 5b of the moving screw cylinder 5 is engaged between the protrusions 10f, 10f of the rotating member 10, and then the piston 7 is attached to the moving body 6. Furthermore, the outer diameter large diameter portion 5 y of the moving screw cylinder 5 is inserted from the large diameter portion 4 x of the screw cylinder 4, and the female screw on the inner peripheral surface of the screw cylinder 4 is inserted into the screwing protrusion 5 e of the outer peripheral surface of the moving screw cylinder 5. 4d is screwed, rotated in the rewinding direction, and retracted to the retreat limit to obtain a temporary assembly.

  Next, the temporary assembly is inserted from the opening side of the main body cylinder 3, and the movable body 6 is fixed to the shaft body while engaging the protrusion 6f of the movable body 6 between the protrusions 3d and 3d of the shaft body 3y of the main body cylinder 3. The screw cylinder 4 is inserted into the main body cylinder 3 while the protrusion 4 a of the screw cylinder 4 is engaged between the protrusions 3 c and 3 c of the main body cylinder 3. Next, the intermediate member 11 is inserted and attached to the main body cylinder 3, and the intermediate member 11 makes the screw cylinder 4 unremovable forward in the axial direction via the rotating member 10 and the rotating member 10. can get.

  On the other hand, in the filling member 1, a predetermined amount of the molten rod M <b> 1 is discharged from the nozzle 14 in the state where the opening 1 a at the front end is closed with the sealing member 13 and inverted, and from the front end to the rear end of the filling member 1. It is made to load in the middle of the state in which there is no space in the tip of the filling member 1. When the molten rod-like object M1 is cooled and solidified to become the rod-like object M, the front end side of the body side assembly 40 is extrapolated from above with respect to the filling member 1 loaded with the rod-like object M, and the piston 7 is filled. While being inserted into the member 1, the filling member 1 is attached to the main body cylinder 3 (intermediate member 11). At this time, the inner peripheral surface of the filling member 1 is engaged with the main body cylinder 3 while being in sliding contact with the annular protrusion 7 c for ensuring the airtightness of the piston 7.

  Then, when the seal member 13 is removed from the bar-like product extrusion container thus obtained, as shown in FIG. 1, the bar-like product extrusion container 100 in the initial state is obtained. The seal member 13 is hygienic when removed by the user (consumer) after purchase. Further, the internal shape of the cap 12 can be changed to be used also as the seal member 13.

  In another manufacturing procedure, as shown in FIG. 18, first, the filling member 1 is mounted on the main assembly 40, and this assembly is placed so that the inclined front end surface 1z of the filling member 1 is horizontal. In addition to being set on the jig 41, a cylindrical heat retaining member 15 made of, for example, a rubber material is extrapolated and set on the tip of the filling member 1. At this time, the inner peripheral surface of the heat retaining member 15 is provided with a step portion 15a having a large inner diameter on the rear side (the lower side in the drawing), and the front end surface 15b constituting the step portion 15a is the filling member 1. The inner peripheral surface in front of the step portion 15a of the heat retaining member 15 and the opening 1a at the tip of the filling member 1 are substantially flush with each other.

  Next, the molten rod-like object M1 is discharged from the nozzle 14 located above the opening at the tip of the heat retaining member 15, and the molten rod-like object M1 is loaded from the piston 7 side. At this time, it is difficult to entrain air between the piston 7 and the molten filler M1, and it is good for pulling back the filler M by the suction action caused by the retraction of the piston 7. Further, the heat retaining member 15 prevents a large amount of the molten filling material M <b> 1 from dripping from the tip of the filling member 1.

  The molten rod M1 is cooled and solidified. At this time, the heat retaining member 15 keeps the tip end of the filling member 1 warm, and therefore the molten rod M1 gradually moves from the piston 7 toward the tip of the filling member 1. The bubbles in the molten rod M1 are well removed from the upper end of the molten rod M1 and the bubbles are prevented from remaining in the rod.

  When the molten rod-like object M1 is cooled and solidified, the heat retaining member 15 is removed, and the tip of the rod-like object M is cut and finished, whereby the rod-like object extrusion container 100 in the initial state shown in FIG. 1 is obtained.

  According to the rod-shaped material extruding container 100 configured in this way, as shown in FIG. 1, the rod-shaped material M is loaded only into the cylindrical filling member 1, so that the thickness of the filling member 1 is relatively uniform. The thickness in the radial direction of the rod-like object M is constant along the axial direction, and it is possible to stabilize the temperature conditions from when the molten rod-like object M1 is loaded to solidification. As a result, it is possible to satisfactorily load the rod-like object M, and the manufacturing yield is improved.

  Moreover, in the rod-shaped product extrusion container shown in FIG. 17, since the filling member 1 loaded with the rod-shaped material M is assembled to the main assembly 40, the manufacture is facilitated. Due to the configuration in which the rod-like object M is loaded on the filling member 1 assembled to the main assembly 40, the manufacture is further facilitated.

Further, since the filling member 1 loaded with the rod-like object M is assembled to the main body side assembly 40 or the filling member 1 assembled to the main body side assembly 40 is loaded with the rod-like object M, it is soft. Even a semi-solid bar, a thin and brittle bar, a soft or jelly- like bar can be safely protected by the filling member 1.

  In this state, the piston 7 is in close contact with the inner peripheral surface of the filling member 1, the rod-like object M is in close contact with the inner peripheral surface of the filling member 1, and the piston 7 and the rod-like object M are in close contact with each other.

  In the rod-like product extrusion container 100 in the initial state shown in FIG. 1 configured as described above, when the cap 12 is removed by the user and the filling member 1 and the main body cylinder 3 are relatively rotated in the feeding direction, The screw cylinder 4 that rotates synchronously with the main body cylinder 3 by the rotation preventing portion 60 between the rotating member 10 that rotates synchronously with the filling member 1 and the moving screw cylinder 5 and the rotation stopper 50 between the main body cylinder 3 and the moving body 6. The moving screw cylinder 5 is relatively rotated, and the moving screw cylinder 5 and the moving body 6 are relatively rotated. Therefore, from the first screwing portion 8 constituted by the screwing protrusion 5e of the moving screw cylinder 5 and the female screw 4d of the screw cylinder 4, and from the female screw 5d of the moving screw cylinder 5 and the male screw 6b of the moving body 6. The screwing action of the configured second screwing portion 9 is activated, the moving screw cylinder 5 moves forward, and the moving body 6 also moves forward relative to the moving screw cylinder 5. In other words, the moving body 6 advances along with the moving screw cylinder 5 and simultaneously advances alone.

  At this time, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9, the moving screw cylinder 5 advances greatly, and the moving body 6 itself advances small. Therefore, the moving body 6 moves forward from the initial state position shown in FIG. 1 by adding a small advance amount of the moving body 6 itself to a large advance amount of the moving screw cylinder 5. Further, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9 in this way, the moving screw cylinder 5 follows the large lead of the first screwing portion 8. Move forward quickly.

  Then, when the moving screw cylinder 5 moves forward quickly in this way, the flange part 5a of the moving screw cylinder 5 comes into contact with the rear end surface of the spring part 10y of the rotating member 10, and the filling member 1 and the main body cylinder 3 in the feeding direction. According to the relative rotation, the spring portion 10y of the rotating member 10 is compressed and accumulates an urging force, while the moving screw cylinder 5 moves forward, and the screwing protrusion 5e of the moving screw cylinder 5 is disengaged from the tip of the female screw 4d of the screw cylinder 4. Then, the screwing of the first screwing portion 8 is released (see FIG. 2).

  In this unscrewed state, the moving screw cylinder 5 is urged rearward by the urging force of the spring portion 10y of the rotating member 10. Therefore, when the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction is further continued, the screwing projection 5e of the moving screw cylinder 5 biased rearward is connected to the female screw 4d in the screw cylinder 4. The first screwing portion 8 is screwed and returned to the tip adjacent to the rotation direction. When the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction is further continued, the moving screw cylinder 5 moves forward while the spring portion 10y of the rotating member 10 is compressed, and the moving screw cylinder 5 is screwed. The protrusion 5e is disengaged from the tip of the female screw 4d of the screw cylinder 4, and the screwing is released, and the screwing is restored by the relative rotation in the same direction, and the screwing of the first screwing part 8 is released. And screwing return is repeated.

  Here, a sliding resistance is generated between the piston 7 attached to the moving body 6 and the inner peripheral surface of the filling member 1, and this sliding resistance is caused by the biasing force of the spring portion 10 y of the rotating member 10. When the first screwing part 8 is screwed back, the resistance of the urging force of the spring part 10y acting on the moving body 6 via the second screwing part 9 becomes resistance, and in some cases, the spring part of the rotating member 10 Although there is a possibility that the first screwing portion 8 is not screwed back with an urging force of 10y, in the present embodiment, as described above, the movable body 6 can move by a predetermined amount in the axial direction with respect to the piston 7. Has been.

  That is, when the moving body 6 is urged rearward via the second screwing portion 9 by the urging force of the spring portion 10y of the rotating member 10 after the screwing of the first screwing portion 8 is released, It moves rearward with respect to the piston 7 without receiving sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1, and the front end surface of the annular groove 6 d of the moving body 6 is formed on the annular protrusion 7 b of the piston 7. The first screwing portion 8 is screwed back at the position where it abuts the base on the tip side. When the moving screw cylinder 5 moves forward while the spring portion 10y of the rotating member 10 is compressed by the further relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction, it moves through the second screwing portion 9. The body 6 moves forward and the screwing of the first screwing part 8 is released. In this way, the mobile body 6 is not subjected to sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1, and the mobile body 6 has a short axial range relative to the piston 7 (the annular groove portion of the mobile body 6). 6d) Going back and forth, the screw release and screw return of the first screwing part 8 are repeated, and the first screwing part 8 is screwed and returned smoothly and satisfactorily.

  Then, the screwing action of the first screwing portion 8 works in this way, the moving screw cylinder 5 moves forward by a predetermined amount and reaches the forward limit, and the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction is performed. In a state where the screw release and screw return of the first screwing part 8 are repeated (the screwing action of the first screwing part 8 is not substantially activated). Only the screwing action of the second screwing part 9 works, and only the moving body 6 moves forward as shown in FIG. When the moving body 6 alone moves forward, as described above, the moving body 6 is short in the predetermined axial direction by repeatedly releasing the screwing of the first screwing portion 8 and returning the screwing. Move forward and back repeatedly within the range.

  Here, in the state where the moving screw cylinder 5 reaches the advance limit and only the moving body 6 moves forward, as described above, the first screwing is performed by the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction. Since the screw release and the screw return of the part 8 are repeated, this causes a click feeling, and the degree of relative rotation in the feed-out direction and the moving condition of the moving body 6 are suitably sensed by the user.

  Then, only the moving body 6 moves forward by the relative rotation accompanied by a click feeling in the feeding direction between the filling member 1 and the main body cylinder 3, and the rod-like object M is pushed out by the piston 7 at the tip and appears through the opening 1a.

  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 moving body 6 is slowly extended according to the small lead of the second screwing portion 9. The rod-like object M appropriately emerges from the opening 1a of the filling member 1 and is put into use. That is, the rod-like object M does not come out too much by mistake.

  When used from the initial state, specifically, when the tip surface of the rod-like object M is near the opening 1a at the tip of the filling member 1 and the moving screw cylinder 5 has not reached the forward limit. In this case, even if the moving screw cylinder 5 does not reach the forward limit, the rod-like object M appears through the opening 1a.

  Then, after use, when the filling member 1 and the main body cylinder 3 are rotated relative to each other in the retraction direction, the screwing protrusion 5e of the moving screw cylinder 5 biased rearward is the female thread 4d of the screw cylinder 4. When the first screwing portion 8 is screwed back and the relative rotation of the filling member 1 and the body tube 3 in the rewinding direction is further continued, the rotation preventing portion 60 and the rotation preventing portion 50 The screwing action of the first screwing part 8 and the second screwing part 9 is activated, the moving screw cylinder 5 is retracted, and the moving body 6 is also retracted with respect to the moving screw cylinder 5. In other words, the moving body 6 is retracted along with the moving screw cylinder 5 and is also retracted alone.

  At this time, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9, the moving screw cylinder 5 is largely retracted, and the moving body 6 itself is retracted small. Therefore, the movable body 6 moves backward by adding the small backward movement amount of the movable body 6 itself to the large backward movement amount of the moving screw cylinder 5. Further, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9 in this way, the moving screw cylinder 5 follows the large lead of the first screwing portion 8. The mobile body 6 moves backward quickly, and the moving body 6 also moves backward with the moving screw cylinder 5.

When the moving screw cylinder 5 and the moving body 6 retreat in this way, as described above, the piston 7 comes into close contact with the inner peripheral surface of the filling member 1, and the rod-like object M comes into close contact with the inner peripheral surface of the filling member 1. 7 and the rod-like object M are in close contact with each other, so that the piston 7 and the rod-like object M are attracted by a suction action (an action to maintain close contact) between the piston 7 and the rod-like object M. The rod-shaped object M is retracted by being pulled back within 1 and is immersed from the opening 1a at the tip of the container. In particular, when the rod-like object M is, for example, a soft or jelly- like rod- like object, the rod- like object M is likely to be in close contact with the filling member 1 and the piston 7, so that the above suction action works better.

  Then, due to the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction, the moving screw cylinder 5 is retracted by a predetermined amount (the moving screw cylinder 5 is retracted by the same amount as the advance amount), which is shown in FIG. As described above, the screw projection 5e of the moving screw cylinder 5 reaches the rear end of the female screw 4d of the screw cylinder 4, and the flange portion 5a of the moving screw cylinder 5 is the inner circumference of the large diameter portion 4x and the small diameter portion 4y of the screw cylinder 4. When it comes into contact with the stepped surface (see FIG. 15) 4e and reaches the retreat limit, the screwing action of the first screwing portion 8 stops and the filling member 1 and the body tube 3 are further relative to each other in the rewinding direction. The rotation stops. That is, the filling member 1 and the main body cylinder 3 cannot be further rotated relative to each other in the retraction direction, and the backward movement of the movable body 6 is also stopped. In this way, since the screwing action of the first screwing portion 8 stops and the relative rotation stops, the rotational force is interfered by the screwing portion 8, and even if a large torque is applied by further rotating in the retraction direction. Torque is not applied to the relatively thin shaft body 3y and the shaft body 3y is not twisted.

  Thus, the moving body 6 at an arbitrary position advanced by a predetermined amount or more from the retreat limit by the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction does not retreat beyond a certain amount. Specifically, the moving body 6 has a small retraction amount of the moving body 6 itself when the moving screw cylinder 5 is retracted from the advancing limit to the retreating limit. It will not retreat beyond the amount added. Therefore, the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction prevents the movable body 6 from returning too much.

  Note that, for example, when the moving screw cylinder 5 at the forward limit is not retracted to the backward limit due to the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction, specifically, the filling member 1 and the main body cylinder 3 Even if the moving body 6 is moved backward by less than a certain amount (within a range not reaching the certain amount), the moving body 6 is kept at a certain amount. It is retreating within the range not reached and not returning too much.

  In this state, that is, from the state in which the moving screw cylinder 5 and the moving body 6 are fed back and the rod-like object M is immersed from the opening 1a at the tip of the container, the user again turns the filling member 1 and the main body cylinder into the use state. 3 is relatively rotated in the feeding direction, the screwing action of the first screwing part 8 and the second screwing part 9 is caused by the anti-rotation part 60 and the anti-rotation part 50 in the same manner as described above. The moving screw cylinder 5 moves forward, and the moving body 6 also moves forward with respect to the moving screw cylinder 5.

  At this time, the moving screw cylinder 5 quickly advances in accordance with the large lead of the first screwing portion 8, and the moving body 6 also advances quickly as the moving screw cylinder 5 advances quickly. Further, since the moving body 6 is prevented from returning too much as described above, it is prevented that the rod-like object M hardly appears from the opening 1a. In other words, usability (ease of use) is improved. Thereafter, the same operation as described above is performed, and such an operation is repeated.

  Moreover, as shown in FIG. 4, when the piston 7 advances to the maximum by the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction, the rod-like object M is almost used up.

  Thus, according to the rod-like product extrusion container 100 of the present embodiment, the piston 7 is in close contact with the filling member 1, and the rod-like product M is in close contact with the filling member 1, and the rod-like product M and the piston 7 are in close contact with each other. Is closely adhered in the filling member 1, the bar M is pushed out as the piston 7 moves forward and emerges from the opening 1 a at the tip of the container, while the piston 7 moves backward between the piston 7 and the bar M as the piston 7 moves backward. The suction action due to the reduced pressure works, and the rod-like object M is pulled back in the filling member 1, so that the rod-like object M can be fed out and fed back without any trouble.

  In addition, when an external action is applied due to an impact or vibration, since the pressure is reduced when the piston 7 and the rod-like object M are separated from each other, the sticking action works. The rod-like object M is prevented from coming out of the container 100.

  Further, as described above, since the rod-like object M is in close contact with the filling member 1 (particularly, the soft rod-like object is in close contact with the filling member 1), even if the rod-like object M is broken in the filling member 1. The broken portion is not detached from the filling member 1 and can be used continuously. Further, the sticking of the rod-shaped object M to the inner wall of the filling member 1 also prevents the rod-shaped object M from coming out of the container 100.

Further, according to the stick-shaped material extruding container 100 of the present embodiment, it is possible to use a soft eg jelly like sticks of especially.

  Furthermore, since the screwing portion of the rod-like product extruding container 100 has a double spiral structure formed by the first and second screwing portions 8 and 9, the length of the rod-like material can be reduced while saving the axial length of the container 100. As described above, the movable body 6 quickly moves forward by a cooperative action of the first and second screwing portions 8 and 9 and advances by a predetermined amount. Since it is possible to move forward slowly by the screwing action of only the screwing portion 9, it is possible to prevent the rod-like object M from being excessively put out by mistake.

  In addition, when the inner peripheral surface of the filling member 1 is gradually tapered toward the tip side (tapered shape), a particularly soft rod-shaped object can be held and an external action such as impact or vibration is added during storage. It is preferable because the rod-like object M is further prevented from falling off and is kept safe.

  Incidentally, while the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9 in this way, the moving body 6 brought along with the moving screw cylinder 5 can be rapidly advanced and retracted. The appearance of the rod-like object M due to the advancement of only the moving body 6 is made moderately slow, but the lead of the first screwing portion 8 and the lead of the second screwing portion 9 are the same, Furthermore, the lead of the first screwing portion 8 can be made smaller than the lead of the second screwing portion 9.

FIG. 19 is a longitudinal sectional view showing the rod-like product extrusion container according to the first embodiment of the present invention. FIG. 20 is a longitudinal sectional view when the moving body is advanced by a user operation from the state shown in FIG. 21 is a longitudinal sectional view when the moving body is retracted from the state shown in FIG. 20 by the operation of the user.

  As shown in FIG. 19, the rod-like material extruding container 500 is provided with a main body cylinder (main body) 401 that forms the latter half of the container and a front half of the container that is relatively rotatable and non-detachable in the axial direction. The filling member 402 is provided as an outer configuration, and the container front part is constituted by the filling member 402 and the container rear part is constituted by the main body tube 401.

  And this rod-shaped object extrusion container 500 is inserted in the main body cylinder 401 inside the rod-shaped object M loaded in the filling member 402 similarly to 1st embodiment, and a rotation prevention part (rotation prevention mechanism). An anti-rotation member 403 connected to the main body cylinder 401 so as to be synchronously rotatable and non-detachable in the axial direction, and a screw cylinder 404 connected to the rear end portion of the filling member 402 so as to be synchronously rotatable and non-detachable in the axial direction; A movable body 406 that engages with the rotation preventing member 403 so as to be able to rotate synchronously and move in the axial direction, and is screwed into the screw cylinder 404 via a threaded portion 405, and is located at the distal end of the movable body 406 and of the filling member 402. And a piston (piston-like extrusion part) 407 inserted into the rear end part.

  And in this rod-shaped article extrusion container 500, the moving body 406 is formed on the outer peripheral surface over the entire length of the cylindrical shape so that the two flat surface portions are opposed to each other, and on the opposing arc-shaped outer peripheral surface between the two flat surface portions. The male screw 406a is configured to include a male screw 406a on the outer periphery of the movable body 406 and a female screw 404a provided on the inner peripheral surface of the screw cylinder 404. The anti-rotation part is constituted by the two plane parts provided over the entire length and the two plane parts on the outer periphery of the moving body 406.

  Further, in this rod-like product extrusion container 500, the piston 407 has an O-ring 408 on its outer peripheral surface, and the O-ring 408 is in close contact with the inner peripheral surface of the filling member 402. For this reason, it is not necessary to make the precision of the inner peripheral surface of the filling member 402 and the outer peripheral surface of the piston 407 high, and manufacturing is easy. Of course, the application of the O-ring can be applied to other embodiments.

  According to such a rod-like material extrusion container 500, when the main body tube 401 and the filling member 402 are relatively rotated in the feeding direction, the screwing action of the screwing part 405 works and cooperates with the rotation preventing part. Accordingly, as shown in FIG. 20, the moving body 406 moves forward, the rod-like object M is pushed out by the piston 407 at the tip, appears through the opening 402a at the tip, and is put into use.

  Then, after use, when the main body tube 401 and the filling member 402 are relatively rotated in the retraction direction, the screwing portion 405 is engaged, and the cooperation with the rotation preventing portion is shown in FIG. Thus, the moving body 406 moves backward.

  Here, as described in the first embodiment, the piston 407 (O-ring 408) is in close contact with the filling member 402, and the rod-like object M is in close contact with the filling member 402, and the rod-like object M. Since the piston 407 and the piston 407 are in close contact with each other in the filling member 402, when the moving body 406 is retracted, a suction action due to decompression acts between the rod-like object M and the piston 407, and the rod-like object M is in the filling member 402. Then, it is pulled back and retracted, and is immersed from the opening 402a at the tip.

  Then, when the main body cylinder 401 and the filling member 402 are relatively rotated in the feeding direction again by the user so that the rod-like object M is put into use from this state, the same operation as described above is performed.

  And as for the assembly procedure of such a rod-shaped object extrusion container 500, the main body side cylinder consisting of the main body cylinder 401 and the anti-rotation member 403 has a screwing portion 405, an extrusion mechanism having an anti-rotation portion, a screw cylinder 404, a piston. A moving body 406 having 407 is provided (incorporated) to obtain a main body side assembly. On the other hand, in the filling member 402, the opening 402a at the front end is closed with a sealing member and turned upside down to a predetermined amount. When the molten rod is discharged from the nozzle and loaded halfway from the front end to the rear end of the filling member 402 so that there is no space in the front end of the filling member 402, the molten rod is cooled and solidified to become a rod M. The main body cylinder 401 and the screw are inserted while inserting the piston 407 into the filling member 402 by inserting the piston 407 into the filling member 402 from the upper side with respect to the filling member 402 loaded with the rod M. 404 To insert the filling member 402. At this time, the filling member 402 is engaged with the main body tube 401 and the screw tube 404 while the inner peripheral surface thereof is in sliding contact with the O-ring 408 for ensuring the airtightness of the piston 407.

  Further, as described with reference to FIG. 18 of the first embodiment, the filling member 402 may be mounted on the main assembly, and then the filling member 402 may be filled with the molten rod-like material.

  According to such a rod-like material extruding container 500, substantially the same effect as the first embodiment (excluding the effect of the double spiral structure and the effect that the moving body at an arbitrary advanced position moves backward by a certain amount and stops). Can be obtained.

FIG. 22 is a longitudinal sectional view showing a rod-like product extrusion container according to the second embodiment of the present invention. As shown in FIG. 22, the rod-like material extruding container 200 includes a filling member 101, and a main body that inserts the latter half portion of the filling member 101 in the front half portion thereof so that the filling member 101 can be synchronously rotated and cannot be detached in the axial direction. A cylinder (main body) 102 and an operation cylinder (operation body) 103 connected to the rear end portion of the main body cylinder 102 so as to be relatively rotatable and non-detachable in the axial direction are provided as external configurations, and a filling member 101 and a main body cylinder A container front part is constituted by 102 and a container rear part is constituted by the operation cylinder 103.

  The rod-like material extruding container 200 is connected to the inside of the rod-like material M loaded in the filling member 101 in the same manner as in the first embodiment and to the operation cylinder 103 so that it can rotate synchronously and cannot move in the axial direction. The screw cylinder 104 is engaged with the main body cylinder 102 so as to be able to rotate synchronously and move in the axial direction, and is engaged with the screw cylinder 104 via the first screwing portion 108, and is synchronized with the operation cylinder 103. A movable body 106 that engages so as to be rotatable and movable in the axial direction and is screwed to the movable screw cylinder 105 via a second screwing portion 109, and a rear portion of the filling member 101 that is attached to the distal end portion of the moving body 106. And a piston (piston-shaped extruding portion) 107 inserted into the end portion.

  According to the rod-like material extruding container 200, when the main body tube 102 (or the filling member 101 is acceptable) and the operation tube 103 are relatively rotated in the feeding direction, the screw projection 105e of the moving screw tube 5 and the female tube 104 are female. The screwing action of the first screwing part 108 constituted by the screw 104d is activated, and the rotation of the moving screw cylinder 105 constituted by the rear half part of the knurling 102a of the main body cylinder 102 and the protrusion 105c of the moving screw cylinder 105 is stopped. The moving screw cylinder 105 moves forward in cooperation with the section 160. At the same time, the screwing action of the second screwing portion 109 constituted by the female screw 105d of the moving screw cylinder 105 and the male screw 106b of the moving body 106 is activated, and the protrusion 103g of the shaft body 103y of the operating cylinder 103 is actuated. In addition, the moving body 106 moves forward by cooperation with the rotation stop portion 150 of the moving body 106 configured by the protrusion 106f of the moving body 106. That is, the moving body 106 moves forward along with the moving screw cylinder 105, and at the same time, moves alone and moves forward quickly.

  Then, when the moving screw cylinder 105 moves forward in this way, the front end surface of the spring portion 105b of the moving screw cylinder 105 comes into contact with the rear end surface of the filling member 101, and the relative rotation of the main body cylinder 102 and the operation cylinder 103 in the feeding direction. Accordingly, while the compression spring 105f of the spring portion 105b of the moving screw cylinder 105 is compressed and accumulates an urging force, the main body portion 105a of the moving screw cylinder 105 moves forward, and the screwing projection 105e of the moving screw cylinder 105 moves to the screw cylinder 104. The first screw 108 is released from the tip of the female screw 104d and the first screw 108 is released.

  In the unscrewed state, the main body portion 105a of the moving screw cylinder 105 is urged rearward by the urging force of the compression spring 105f of the moving screw cylinder 105. Therefore, when the relative rotation of the main body cylinder 102 and the operation cylinder 103 in the extending direction is further continued, the screwing protrusion 105e of the main body portion 105a of the moving screw cylinder 105 biased rearward is connected to the female cylinder 104. The screw 104d enters the tip adjacent to the rotation direction, and the first screwing portion 108 is screwed back. When the relative rotation of the main body cylinder 102 and the operation cylinder 103 continues further in the extending direction, the main body portion 105a of the moving screw cylinder 105 moves forward while the compression spring 105f of the moving screw cylinder 105 is compressed, and the moving screw. The threaded projection 105e of the cylinder 105 is released from the tip of the female thread 104d of the threaded cylinder 104, the threaded engagement is released, and the threading is restored by relative rotation in the same direction. The screw release 108 and the screw return are repeated.

  In this way, the screwing action of the first screwing portion 108 works to move the moving screw cylinder 105 forward by a predetermined amount to reach the forward limit, and relative rotation of the main body cylinder 102 and the operation cylinder 103 in the feeding direction is performed. In a state where the screw release and screw return of the first screwing portion 108 are repeated (the screwing action of the first screwing portion 108 is not substantially activated). Only the screwing action of the second screwing part 109 works, and only the moving body 106 moves forward slowly by cooperation with the rotation preventing part 150 of the moving body 106.

  Then, only the moving body 106 moves forward by the relative rotation of the main body cylinder 102 and the operation cylinder 103 in the extending direction, and the rod-like object M is pushed out by the piston 107 at the front end and appears through the opening 101a at the front end to be used. The In the present embodiment, the opening 101a is narrower than the rear cylindrical hole (the cylindrical hole of the filling member 101).

  When the main body cylinder 102 and the operation cylinder 103 are rotated relative to each other in the retraction direction after use, the screwing protrusion 105e of the moving screw cylinder 105 biased rearward is the female thread 104d of the screw cylinder 104. When the first screwing portion 108 is screwed back and the relative rotation of the main body tube 102 and the operation tube 103 in the retraction direction is further continued, the first screwing portion 108 is screwed. The operation is performed without any problem, and the moving screw cylinder 105 moves backward by cooperation with the rotation preventing portion 160 of the moving screw cylinder 105. At the same time, the screwing action of the second screwing part 109 is activated, and the moving body 106 moves backward by cooperation with the rotation preventing part 150 of the moving body 106. That is, the moving body 106 is retracted along with the moving screw cylinder 105 and at the same time is retracted alone, and is quickly retracted.

  Here, in the same manner as described in the first embodiment, the piston 107 is in close contact with the filling member 101, the rod-like object M is in close contact with the filling member 101, and the rod-like object M and the piston 107 are filled. Due to the close contact within the member 101, when the moving body 106 is retracted, a suction action due to decompression acts between the rod-like object M and the piston 107, and the rod-like object M is pulled back within the filling member 101 to move backward. To do.

  Then, due to the relative rotation of the main body cylinder 102 and the operation cylinder 103 in the retraction direction, the moving screw cylinder 105 is retracted by a predetermined amount (the moving screw cylinder 105 is retracted by the same amount as the advance amount), and the moving screw cylinder 105 When the screwing projection 105e reaches the rear end of the female screw 104d of the screw tube 104 and reaches the retreat limit, the screwing action of the first screwing portion 108 stops and the retraction direction between the main body tube 102 and the operation tube 103 is reached. Further relative rotation to the stops. That is, the main body cylinder 102 and the operation cylinder 103 can no longer be rotated relative to each other in the retraction direction, and the backward movement of the moving body 106 is also stopped.

  As described above, the movable body 106 at an arbitrary position advanced by a certain amount or more from the retreat limit by the relative rotation of the main body tube 102 and the operation tube 103 in the retraction direction does not retreat beyond the certain amount. Specifically, the moving body 106 has a small retraction amount of the moving body 106 itself when the moving screw cylinder 105 retreats from the advance limit to the retreat limit to a predetermined amount that the move screw cylinder 105 retreats from the advance limit to the retreat limit. It will not retreat beyond the amount added. Accordingly, the mobile body 106 is prevented from returning too much due to the relative rotation of the main body cylinder 102 and the operation cylinder 103 in the retraction direction.

  Then, when the user rotates the main body cylinder 102 and the operation cylinder 103 again relative to each other in the extending direction so that the rod-like object M is put into use from this state, the same operation as described above is performed.

  In this embodiment, the O-ring 115 for providing good sliding rotation resistance between the main body cylinder 102 and the operation cylinder 103 and preventing radial backlash is provided between the main body cylinder 102 and the operation cylinder. 103.

  As an assembly procedure for such a rod-like material extruding container 200, the first and second screwing portions 108 and 109, the rotation preventing portions 150 and 160 are provided in the main body side cylinder including the main body tube 102 and the operation tube 103. A push-out mechanism, a screw cylinder 104, a moving screw cylinder 105, a moving body 106, and a piston 107 are provided (incorporated) to obtain a main assembly. On the other hand, the filling member 101 has an opening 101a at the tip. In a state where the sealing member is closed and inverted, a predetermined amount of a molten rod-like object is discharged from the nozzle and is loaded halfway from the front end to the rear end of the filling member 101 so that there is no space in the front end of the filling member 101. When the molten rod-like material is cooled and solidified to become the rod-like material M, the tip side of the main assembly is extrapolated from above with respect to the filling member 101 loaded with the rod-like material M, and the piston 107 is inserted into the filling member 1. While inserting the 1, mounting the filling member 101 to the main body tube 102. At this time, the inner circumferential surface of the filling member 101 is engaged with the main body cylinder 102 while being in sliding contact with the annular protrusion 107 c for ensuring the airtightness of the piston 107.

  Further, as described with reference to FIG. 18 of the first embodiment, the filling member 101 may be mounted on the main assembly, and then the molten rod-shaped object may be loaded into the filling member 101.

  According to such a rod-like product extrusion container 200, substantially the same effect as that of the first embodiment can be obtained. In addition, since the opening 101a at the tip of the filling member 101 is narrower than the cylindrical hole on the rear side (the cylindrical hole of the filling member 101), a particularly soft rod-like object can be held, and shock, vibration, etc. can be stored during storage. When the external action is added, the rod-like object M is further prevented from falling off and is kept safe. And since the rod-shaped object M once solidified is pushed out by the piston 107 while narrowing down the narrow opening 101a, the composition collapses and becomes soft, and the feeling of use is moderate.

  In addition, by making the filling member 101 transparent, the color of the rod-like object M can be confirmed through the flange portion 101z of the filling member 101 in a state where the tip portion is capped.

FIG. 23 is a longitudinal sectional view showing a rod-like product extrusion container according to the second reference embodiment of the present invention, and FIG. 24 is an enlarged view of part A in FIG. As shown in FIG. 23, the rod-like product extrusion container 300 includes a front tube 253 that forms both distal ends (left and right ends in the drawing) of the container, a main body tube (main body) 251 that forms a rear side of the front tube 253, And the front tube 253 constitutes the front portion of the container, and the main body tube 251 constitutes the rear portion of the container.

  And this rod-shaped object extrusion container 300 comprises the connection member 252 for connecting the front tube 253 to the main body tube 251 so as to be relatively rotatable and immovable in the axial direction, and a rotation preventing portion (rotation preventing mechanism). The pipe member moving body 205 that moves forward / backward when the rotation preventing member 257, the main body tube 251 and the front tube 253 are relatively rotated, and the pipe member that moves forward / backward as the pipe member moving body 205 moves forward / backward. (Filling member) 254, the rod-like object M loaded in the pipe member 254 in the same manner as in the above embodiment, and the pipe member moving body 205 is moved forward / backward, so that the pipe member 254 reaches the forward limit. When the main cylinder 251 and the front cylinder 253 are further rotated relative to each other in the extension direction, the pipe member 254 reaches the retreat limit and the main cylinder 251 and the front cylinder 253 are further advanced. The rod-like object moving body (moving body) 256 that moves backward when it is relatively rotated in this direction, and a piston (piston-like shape) that is attached to the distal end portion of the rod-like object moving body 256 and inserted into the rear end portion of the pipe member 254 ) 256x, a first screwing portion 258 that enables movement of the pipe member moving body 205, and a second screwing portion 259 that enables movement of the rod-like object moving body 256. I have.

  In this rod-like material extruding container 300, the first screwing portion 258 is constituted by the screwing protrusion 205 e of the pipe member moving body 205 and the spiral groove 253 i of the front tube 253, and the female screw of the pipe member moving body 205. 205j and the male screw 256b of the rod-like object moving body 256 constitute a second screwing portion 259, and the anti-rotation portion 270 from the two flat surface portions 257e of the anti-rotation member 257 and the two flat surface portions 256a of the rod-like object moving body 256. Is configured.

In addition, in this reference form, the screwing action of the first screwing portion 258 is increased by making the lead of the first screwing portion 258 larger than the lead of the second screwing portion 259. The second screwing portion 259 works before the screwing action. For example, the operating resistance of the second screwing portion 259 is increased as compared with the first screwing portion 258 by, for example, changing the material, so that the screwing action of the first screwing portion 258 is increased. You may make it act | operate before the screwing effect | action of the 2nd screwing part 259. FIG.

  In such a rod-like material extruding container 300, in the initial state, as shown in FIGS. 23 and 24, the pipe member 254 and the pipe member moving body 205 have reached the forward limit. In this state, when the main body cylinder 251 and the front cylinder 253 are relatively rotated in the feeding direction, the screwing action of the first screwing part 258 is in a stopped state, so that the screwing of the second screwing part 259 is stopped. The combined action works, and the rod-shaped object moving body 256 is slowly fed out by the cooperation with the rotation preventing portion 270, and the rod-like object M is slowly pushed out by the piston 256x at the tip, and appears from the pipe member 254 to be used. .

  Then, after the use, when the main body cylinder 251 and the front cylinder 253 are relatively rotated in the rewinding direction, the first screwing portion 258 is first screwed, and in cooperation with the rotation preventing portion 270, The pipe member moving body 205 is quickly retracted along with the rod-like object moving body 256.

  Here, as described in the first embodiment, the piston 256x is in close contact with the pipe member 254, the rod M is in close contact with the pipe member 254, and the rod M and the piston 256x are pipes. Since the rod-like object moving body 256 is retracted, the piston 256x is retracted with the pipe member 254 and the pipe member 254 is retracted with the rod-like object M when the rod-like object moving body 256 is retracted. And the tip of the rod-like object M is immersed from the opening at the tip of the front tube 253, and the pipe member 254 is returned to the accommodation position in the front tube 253.

  When the rear end surface of the pipe member moving body 205 reaches the retreat limit where it abuts against the front end surface of the rotation preventing member 257, the screw member protrusion 205e of the pipe member moving body 205 is prevented from further retreating. The screwing action of the screwing part 258 stops. In this state, when the main body cylinder 251 and the front cylinder 253 are continuously rotated relative to each other in the retraction direction, the screwing action of the first screwing part 258 is stopped, so that the second screwing part 259 is stopped. The rod-like object moving body 256 is slowly retracted by the cooperation of the non-rotating portion 270. At this time, the pipe member 254 is prevented from further retreating by the pipe member moving body 205, and a suction action by decompression acts between the rod-like object M and the piston 256x. Retreating together with 256x, the tip of the rod-like object M is also accommodated in the pipe member 254.

  In this state, when the main body cylinder 251 and the front cylinder 253 are relatively rotated in the pay-out direction by the user, the screwing action of the first screwing portion 258 works and the pipe member 254 including the rod-like object moving body 256. Advances rapidly until the screwing action of the first screwing portion 258 is stopped, and thereafter the same operation as described above is performed.

  And as for the assembly procedure of such a rod-shaped object extrusion container 300, in the main body cylinder 251, the extrusion mechanism provided with the 1st and 2nd screwing parts 258 and 259, the rotation prevention part 270, and the moving body 205 for pipe members. The connecting member 252, the anti-rotation member 257, the rod-like object moving body 256, and the piston 256 x are provided (built in) to obtain a main assembly side assembly. In this state, the pipe member moving body 205 is in the forward limit position as shown in FIG. On the other hand, on the front tube 253 side, with the opening at the tip of the pipe member 254 closed with a seal member, a predetermined amount of molten rod-like material is discharged from the nozzle to the rear from the tip of the pipe member 254. When the molten rod-like material is cooled and solidified to become a rod-like material M after being loaded halfway to the end and without a space in the tip of the pipe member 254, the pipe member 254 loaded with the rod-like material M is attached to the front tube 253. With respect to the front tube 253 containing the pipe member 254, the front end side of the main body side assembly is inserted from above and the piston 256x is inserted into the pipe member 254. The leading tube 253 is mounted on the connecting member 252 mounted on the main body tube 251. At this time, the front tube 253 containing the pipe member 254 is engaged with the connecting member 252 while the inner peripheral surface of the pipe member 254 is in sliding contact with the outer peripheral surface of the piston 256x.

  Similarly to the case described with reference to FIG. 18 of the first embodiment, after the front tube 253 containing the pipe member 254 is attached to the main assembly, the pipe member 254 is loaded with a molten rod-like object. May be.

FIG. 25 is a longitudinal sectional view showing an initial state of the rod-like product extrusion container according to the third embodiment of the present invention, and FIG. 26 shows that the moving screw cylinder and the moving body are advanced by the user's operation from the state shown in FIG. It is a longitudinal cross-sectional view at the time. As shown in FIG. 25, the rod-like material extruding container 400 is rotated relative to the main body cylinder 31 through a main body cylinder (main body) 301 that forms the latter half of the container and a front half holding member 302 that forms the front half of the container. The front tube 303 is connected to the front tube 303 as an outer configuration. The front tube 303 forms a front portion of the container, and the main body tube 301 including the front tube holding member 302 forms a rear portion of the container.

  The rod-like material extruding container 400 includes a pipe member (filling member) 304, a rod-like material M loaded in the pipe member 304 as in the first embodiment, and the pipe member 304. Further, a female screw member 305 that is connected so as not to be disengageable in the axial direction and moves forward / backward when the main body tube 301 and the front tube 303 are rotated relative to each other, and a female screw engaged with the main body tube 301 so as to be able to rotate synchronously and move in the axial direction A rotating member 316 that moves forward / backward in accordance with the forward / backward movement of the member 305, and a pipe member that engages with the rotating member 316 so as to be able to rotate synchronously and move in the axial direction, and move forward / backward as the female screw member 305 moves forward / backward. When the main body tube 301 and the front tube 303 are further rotated relative to each other in the same direction, the moving body 306 moves forward, and the pipe portion is attached to the distal end of the moving body 306. A piston (piston-like push-out portion) 307 inserted into the rear end portion 304, a first screwing portion 308 that enables movement of the female screw member 305, and a second that enables movement of the moving body 306. The screwing portion 309 is roughly provided.

A second screwing portion 309 is constituted by the male screw 306b, and a rotation preventing portion 350 is constituted by the protrusion 306d of the moving body 306 and the protrusion 316e of the shaft body 316y of the rotating member 316.

In this reference embodiment, the operating resistance of the second screwing portion 309 is increased by tightening the female screw member 305 by the elastic force of the O-ring 311 attached to the outer surface of the female screw member 305. The operating resistance of the first screwing portion 308 is set higher than that of the first screwing portion 308, so that the screwing action of the first screwing portion 308 is performed before the screwing action of the second screwing portion 309. ing. In addition, by making the lead of the first screwing portion 308 larger than the lead of the second screwing portion 309, the screwing action of the first screwing portion 308 can be reduced by the second screwing portion 309. It is also possible to work before the screwing action.

  When the female screw member 305 moves forward by a predetermined amount, the annular protrusion 305k of the female screw member 305 locks the convex portion 316d of the rotating member 316 in the axial direction, and the main body cylinder 301 and the leading cylinder 303 continue to feed out. 26, as shown in FIG. 26, the female screw member 305 moves forward with the rotating member 316 by the engagement of the annular projecting portion 305k and the convex portion 316d, and the leading end of the pipe member 304 at the front end portion While the protrusion amount from 303 increases, the pipe member 304 moves forward to the forward limit where the screw projection 305e of the female screw member 305 is positioned at the tip 303f of the screw groove 303b of the front tube 303, and the first screw portion When the screwing action of 308 is stopped and the main body tube 301 and the leading tube 303 are subsequently rotated relative to each other in the feeding direction, the screwing action of the second screwing portion 309 is activated and cooperates with the rotation preventing portion 350. Work, Body 306 and the piston 307 is slowly advanced, the stick-shaped material M is the appearance and use state from the front end of the pipe member 304 is pushed out by the piston 307.

  When the main body cylinder 301 and the front cylinder 303 are relatively rotated in the retraction direction after use, the screwing action of the first screwing portion 308 works, and the female screw member 305 is cooperated with the rotation preventing portion 350. The moving member 306 and the piston 307 are quickly retracted 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 303, and the rear end surface of the rotating member 316 is in contact with the bottom surface of the main body tube 301.

The other configurations are the same, and the same reference numerals as those of the moving screw cylinder 5 are attached to the other same configurations. The elongated holes 5c shown in FIGS. 10 and 11 are omitted here.

  As shown in FIG. 27, the intermediate member 511 has a shape without the spring portion 11y of the intermediate member 11 shown in FIG. 7, and the other configurations are the same.

  The rotating member 510 is configured such that the protrusion 10b of the rotating member 10 shown in FIG. 12 is eliminated, and the flange portion 10a and the spring portion 10y are positioned in front of the rotating member 10. The other configurations are the same, and the same reference numerals as those of the rotating member 10 are assigned to the other same configurations. With this change, the screw cylinder 4 and the moving screw cylinder 505 are also configured to be positioned on the front side of the first embodiment.

  In the rod-like product extruding container 600 in the initial state shown in FIG. 27, the moving screw tube 505 is in contact with the bottom surface of the main body tube 3 and the screw projection 5e is attached to the front side. The first screwing portion 8 is configured by being screwed into the rear end of the female screw 4 d of the screw cylinder 4. The flange portion 10 a of the rotating member 510 is located between the front end surface of the screw cylinder 4 and the rear end surface of the intermediate member 511, and cannot be separated in the axial direction by the rear end of the intermediate member 511. It is possible to rotate relative to the rear end.

  In the rod-like product extruding container 600 in the initial state shown in FIG. 27 configured as described above, the forward movement operation of the moving body 6 is the same as that of the first embodiment. That is, when the filling member 1 and the main body cylinder 3 are relatively rotated in the feeding direction, the screwing action of the first screwing part 8 and the second screwing part 9 is activated, and the moving screw cylinder 505 moves forward. Furthermore, the moving body 6 also moves forward with respect to the moving screw cylinder 505. That is, the moving body 6 moves forward along with the moving screw cylinder 505, and at the same time, moves alone and moves forward quickly.

  When the moving screw cylinder 505 moves forward by a predetermined amount and the stepped surface 505p comes into contact with the rear end surface of the spring portion 10y of the rotating member 510, the spring portion 10y releases the screwing of the first screwing portion 8 and returns the screwing. In this state, the moving body 6 moves back and forth within a short range in a predetermined axial direction with respect to the piston 7 without receiving a sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1. To do. And when the relative rotation is further made in the same direction, only the screwing action of the second screwing part 9 works in the state where the screwing release and screwing return of the first screwing part 8 are repeated, As shown in FIG. 28, only the moving body 6 moves forward slowly, and the rod-like object M is pushed out by the piston 7 at the tip, and slowly appears through the opening 1a to be used.

  Then, after use, when the filling member 1 and the main body cylinder 3 are relatively rotated in the rewinding direction, the first screwing portion 8 is screwed back by the spring portion 10y of the rotating member 510, and further in the same direction. As a result of the relative rotation, the screwing action of the first screwing part 8 and the second screwing part 9 is activated, the moving screw cylinder 505 is retracted, and the moving body 6 is also moved relative to the moving screw cylinder 505. fall back. In other words, the moving body 6 is retracted along with the moving screw cylinder 505 and at the same time is retracted alone and quickly retracts.

  Here, as described in the first embodiment, the piston 7 is in close contact with the inner peripheral surface of the filling member 1, and the rod-like object M is in close contact with the filling member 1, and the rod-like object M and the piston Since 7 is in close contact with the filling member 1, when the moving body 6 is retracted, a suction action due to decompression acts between the rod-like object M and the piston 7, and the rod-like object M is pulled back within the filling member 1. Retreat.

  Then, when the moving screw cylinder 505 is retracted by further relative rotation in the same direction, the rear end surface of the spring portion 505y of the moving screw cylinder 505 is brought into contact with the bottom surface of the main body cylinder 3, as shown in FIG. When abutting and further rotating in the same direction, the spring portion 505y of the moving screw cylinder 505 is compressed and stores the urging force, while the moving screw cylinder 505 is retracted, and the screwing projection 5e of the moving screw cylinder 505 is screwed. The first screw 8 is released from the tip of the female screw 4d of the tube 4 and the screwing of the first screwing portion 8 is released.

  In this unscrewed state, the moving screw cylinder 505 is urged forward by the urging force of the spring portion 505y of the moving screw cylinder 505. Therefore, when the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction is further continued, the screwing projection 5e of the moving screw cylinder 505 biased forward is the female thread 4d in the screw cylinder 4. The first screwing part 8 is screwed and returned to the rear end adjacent to the rotation direction. When the relative rotation of the filling member 1 and the main body cylinder 3 in the retraction direction is further continued, the moving screw cylinder 5 is retracted while the spring portion 505y of the moving screw cylinder 505 is compressed, and the moving screw cylinder 505 is retreated. The screwing protrusion 5e is released from the tip of the female screw 4d of the screw cylinder 4, and the screwing is released. Then, the screwing is restored by relative rotation in the same direction, and the screwing of the first screwing part 8 is performed. The combination release and screwing return are repeated.

  In this state, the moving body 6 is short in the predetermined axial direction with respect to the piston 7 without receiving a sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1 as in the case of forward movement. Go back and forth within range. When the relative rotation in the same direction is further continued, only the screwing action of the second screwing part 9 is performed in a state where the screwing release and screwing return of the first screwing part 8 are repeated. Thus, only the moving body 6 moves backward slowly and can move back to the initial position shown in FIG. Thus, since the moving body 6 moves backward slowly, the rod-like object M is prevented from returning too much, and can be finely adjusted thereafter.

  In addition, as shown in FIG. 30, when the piston 7 moves forward to the maximum by the relative rotation of the filling member 1 and the main body cylinder 3 in the feeding direction, the rod-like object M is almost used up.

  And the assembly procedure of such a rod-shaped object extrusion container 600 is the same as that of 1st embodiment.

  According to such a rod-like product extrusion container 600, it is possible to obtain substantially the same effect as the first embodiment (excluding the effect that the movable body 6 at an arbitrary position advanced advances backward by a certain amount and stops). In addition, after the movable body 6 is quickly retracted by a cooperative action of the first screwing part 8 and the second screwing part 9 and is retracted by a predetermined amount, only the second screwing part 9 is screwed. It is possible to retreat slowly.
