Description

  The present invention relates to a rod-like product extrusion container for extruding and using a rod-like material.

  Conventionally, as a method for filling a bar-shaped cosmetic container with a bar-shaped cosmetic, a method for charging a bar-shaped cosmetic container that has been assembled with a pre-manufactured bar-shaped cosmetic or a molten bar-shaped cosmetic in the filling member In the case of a thin stick-shaped cosmetic or a brittle stick-shaped cosmetic, for example, in order to protect the stick-shaped cosmetic, the latter filling member is filled. A method of filling a molten bar-shaped cosmetic material forming material by cooling and solidifying it is adopted. In this latter filling method, cosmetics (molten cosmetics), a method of injecting a large amount from the tip of the filling member of the finished bar-shaped cosmetic container, cutting the tip after cooling, and finishing processing, In order to eliminate sink marks at the tip after cooling and solidification, there is known a method of remelting and adjusting by applying hot air, but a process for finishing the tip is required, and the manufacturing cost cannot be reduced.

Therefore, a technique that does not require finishing is disclosed in Patent Document 1 below. The stick-shaped cosmetic container described in Patent Document 1 includes a cylindrical filling member (sleeve) having both ends opened, and a cylindrical operation cylinder (operation) that connects the filling member so as to be relatively rotatable and immovable in the axial direction. Part), a cylindrical pushing part (inner tray) that is mounted in the latter half of the filling member so as not to rotate and to be movable in the axial direction, and a filling member that is fitted with the pushing part and has a lid attached to the tip. And a rod-shaped cosmetic that is directly filled and molded from the rear end side of the filling member. When the filling member and the operation cylinder are rotated relative to each other, the push-out portion moves forward and backward with respect to the filling member. The cosmetic material appears and disappears from the tip of the filling member.

  However, in the stick-shaped cosmetic container having such a configuration, since the cosmetic material (molten cosmetic material) is filled in the filling member having the extruding portion attached to the latter half portion, the members overlap and the diameter of the cosmetic material is increased. The thickness of the direction is different along the axial direction, and it is difficult to stabilize the temperature conditions from filling the cosmetic to solidifying, and as a result, the stick-shaped cosmetic tends to be defective products such as sinks and cracks, and the production yield There is a problem that gets worse.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a rod-shaped product extrusion container in which a rod-shaped material such as a rod-shaped cosmetic is satisfactorily filled and the production yield is improved. And

A rod-like material extrusion container according to the present invention comprises a cylindrical filling member that is attached to a container and that is open at both ends, and a rod-like material that is filled in the filling member, 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, and the rod-like product extruding container in which the rod-like product emerges from the opening at the tip of the container. When the container front part and the container rear part are relatively rotated in one direction, the first screwing part and the second screwing part are screwed together. When the moving body advances together and the screwing of the first screwing part is released, only the screwing action of the second screwing part works and the moving body moves forward, and the inside of the container Is provided with an extruding portion which is located at the front end of the moving body and slides inside the filling member, and the rod-shaped object is provided midway from the front end to the rear end of the filling member Is Hama, when assembling the filling member which the stick-shaped material is filled into the container, the extrusion unit together with the filling member is mounted on the container is being inserted into the filling member.

  According to such a rod-like material extrusion container, since the rod-like material is filled only in the cylindrical filling member opened at both ends, the thickness of the filling member is relatively uniform and the thickness of the rod-like material in the radial direction is small. It is constant along the axial direction, and it is possible to stabilize the temperature conditions from filling the molten rod-shaped material to solidifying, and as a result, it is possible to satisfactorily fill the rod-shaped material and improve the production yield. The Further, since the filling member filled with the rod-like material is assembled to the container, the manufacturing is facilitated. In addition, since the rod-shaped object is filled halfway from the front end to the rear end of the filling member, it is prevented that the rod-shaped object is pushed out by the extruding part and appears from the filling member when the filling member is attached to the container. Thus, there is no need for finishing or the like, and the manufacturing is facilitated.

  Here, in the configuration in which the filling member filled with the rod-like material is assembled to the container and the extrusion portion is inserted into the filling member, it is difficult to manufacture the clearance between the rod-like material and the extrusion portion to be zero. is there.

  Therefore, when the mounting of the filling member to the container is completed, there is a space between the rod-shaped object filled in the filling member and the push-out portion inserted into the filling member. Prevent it from appearing.

  However, if such a space remains, it is not preferable because the extruding part advances and compresses the air, which causes a delay in the appearance of the rod-like material from the tip, etc., so the filling member and the extruding part are in close contact with each other. It is preferable to provide a ventilation part for releasing air. When such a configuration is adopted, the air in the space between the rod-shaped object in the filling member and the extrusion portion is released through the ventilation portion. In addition, as described above, when the air in the space between the rod-shaped object in the filling member and the extruding part is released through the ventilation part, the container front part and the container rear part are opposite in one direction. When the extruding portion that has been relatively rotated in the other direction and moved forward moves backward, the pressure reducing action (keeping the sealed state) in the filling member makes it easier to pull the rod-like object back in the filling member as the pushing portion moves backward. Here, if the rod-like object is, for example, a soft or gel-like rod-like object, the rod-like object is easy to be in close contact with the filling member, which is convenient for moving the rod-like object backward.

  Here, as such a ventilation part, specifically, the ventilation is opened in order to allow the air in the space to escape in a state where the filling member is mounted, and the ventilation is closed by the advancement of the pushing part by a predetermined amount. A configuration is mentioned.

  Further, the filling member and the extruding part are in close contact, and when the filling member is attached to the container, the air between the rod-like material filled in the filling member and the extruding part inserted into the filling member is released. You may employ | adopt the structure provided with a ventilation part.

  As such a ventilation part, specifically, there is a configuration in which ventilation is opened in order to allow air to escape when the filling member is mounted, and the ventilation is closed when the mounting is completed.

  In addition, as a ventilation portion that effectively exhibits the above-described action, specifically, a groove provided inside the filling member, a hole communicating the inside and the outside of the filling member, or the outside of the extrusion portion Any of the groove | channel provided, or the hole which connects the rod-shaped object side and moving body side of an extrusion part is mentioned.

  As described above, according to the present invention, it is possible to provide a rod-like product extrusion container that improves the production yield and facilitates the production.

  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 be in a state where there is no space in the front end of the filling member 1 by filling in part. When the molten rod-like object M1 is cooled and solidified to become the rod-like object M, the tip side of the main assembly 40 is extrapolated from above to the filling member 1 filled 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.

  Upon completion of the mounting of the filling member 1, as shown in FIG. 18, the air vent groove 1i on the inner peripheral surface of the filling member 1 is positioned so as to cross the annular protrusion 7c of the piston 7 in the axial direction. As shown in FIG. 1, a space Z is formed between the rod-like object M filled in the filling member 1 and the piston 7 inserted in the filling member 1.

  The space Z is formed in such a structure that the filling member 1 filled with the rod-like object M is assembled to the main assembly 40 and the piston 7 is inserted into the filling member 1. This is because if the gap between the first and second members is set to zero, the rod-like object M may be pushed out by the piston 7 and appear from the filling member 1. In this embodiment, in order to avoid this, a space is used. Z is provided.

  Then, when the sealing member 13 is removed from the rod-like product extrusion container thus obtained, as shown in FIG. 1, the rod-like product extrusion vessel 100 in an initial state in which there is no space in the tip of the filling member 1 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.

  According to the rod-like product extruding container 100 configured in this way, as shown in FIG. 17, only the cylindrical filling member 1 is filled with the rod-like material M, so that the thickness of the filling member 1 is relatively uniform. The thickness of the rod-like object M in the radial direction is constant along the axial direction, and it is possible to stabilize the temperature condition from filling the molten rod-like object M1 to solidification. Further, since the filling member 1 filled with the rod-like object M is assembled to the main assembly 40, the manufacture is facilitated. Further, since the rod-like object M is filled from the front end to the rear end of the filling member 1, the rod-like object M is pushed out by the piston 7 when the filling member 1 is attached to the main assembly 40. Appearance from the filling member 1 is prevented.

  Further, since the filling member 1 filled with the rod-like material M is assembled to the main assembly 40 in this way, it is a soft semi-solid rod-like material, a thin and brittle rod-like material, a soft or gel-like rod-like material. However, it is safely protected by the filling member 1.

  1, 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 moving screw cylinder 5 The screwing action of the first screwing portion 8 constituted by the screwing protrusion 5e and the female screw 4d of the screw cylinder 4 is activated, and the protrusion 6f of the movable body 6 and the protrusion of the shaft body 3y of the main body cylinder 3 are actuated. The moving screw cylinder 5 moves forward by cooperation with the rotation stopper 50 constituted by 3d. At the same time, the screwing action of the second screwing portion 9 constituted by the female screw 5d of the moving screw cylinder 5 and the male screw 6b of the moving body 6 is activated, and the movement is made in cooperation with the rotation preventing portion 50. The body 6 moves forward. 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, from the initial state shown in FIG. 18, that is, the state where the air vent groove 1 i is opened to release the air in the space Z, the piston 7 moves forward by a predetermined amount while sliding inside the filling member 1 as described above. As shown in FIG. 19, the air in the space Z is released to the rear side through the air vent groove 1i, and the space Z is immediately eliminated, and the ventilation of the air vent groove 1i is closed, and the piston 7 and the rod-like object M Is in an airtight state in the filling member 1.

  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, the moving body 6 is moved rearward from the position shown in FIG. 19 via the second screwing portion 9 by the biasing force of the spring portion 10y of the rotating member 10 when the screwing of the first screwing portion 8 is released. When it is urged, 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 tip surface of the annular groove 6d of the moving body 6 is the piston. The first screwing portion 8 is screwed back at a position where it comes into contact with the base of the tip end side of the annular projection 7b. 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 to the state shown in FIG. 19 and the screwing of the first screwing portion 8 is released. Thus, without receiving sliding resistance between the piston 7 and the inner peripheral surface of the filling region 1, the moving body 6 is a short range in the predetermined axial direction with respect to the piston 7 (the annular groove portion of the moving 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. 2 by cooperation with the rotation preventing part 50 of the moving body 6. 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.

  In addition, there is no space in the tip of the filling member 1 in the initial state, and the space Z is immediately lost as shown in FIG. Immediately emerges from the opening 1c.

  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 operation tube 3 in the rewinding direction is further continued, the first screwing portion 8 is screwed. The operation is performed without any problem, and the moving screw cylinder 5 is retracted by cooperation with the rotation stopper 50 of the moving body 6. At the same time, the screwing action of the second screwing portion 9 is activated, and the moving body 6 moves backward by cooperation with the rotation preventing portion 50 of the moving body 6. 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 space Z is eliminated, and the piston 7 and the rod-like object M are in an airtight state in the filling member 1. The rod-like object M is retracted and retracted in the filling member 1 as the piston 7 is retracted by the pressure reducing action (the action of maintaining a sealed state) in the filling member 1. When the rod-like object M is, for example, a soft or gel-like rod-like object, the rod-like object M is easily in close contact with the filling member 1, which is convenient for moving the rod-like object M backward.

  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 where the moving screw cylinder 5 and the moving body 6 are retreated, the filling member 1 and the main body cylinder 3 are rotated relative to each other in the unwinding direction again by the user so that the rod-like object M is used. In the same manner as described above, the screwing action of the first screwing portion 8 is activated, and the moving screw cylinder 5 is advanced by the cooperation with the rotation preventing portion 50 of the moving body 6, and the second screwing is performed. The screwing action of the joint portion 9 is activated, and the movable body 6 moves forward by cooperation with the rotation preventing portion 50.

  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. 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.

  As described above, according to the rod-like product extrusion container 100 of the present embodiment, since only the filling member 1 is filled with the rod-like material M, the thickness of the filling member 1 is relatively uniform and the rod-like material M is thick in the radial direction. Is constant along the axial direction, and it is possible to stabilize the temperature conditions from filling the molten rod-like material M1 to solidification. Therefore, it is possible to satisfactorily fill the rod-like object M, and the manufacturing yield is improved. Further, since the filling member 1 filled with the rod-like object M is assembled to the main assembly (container) 40, the manufacture is facilitated. Further, since the rod-like object M is filled from the front end to the rear end of the filling member 1, the rod-like object M is pushed out by the piston 7 when the filling member 1 is attached to the main assembly 40. It is prevented from appearing from the filling member 1, and there is no need for finishing or the like, and manufacturing is easy.

  In addition, when the mounting of the filling member 1 to the main assembly 40 is completed, there is a space Z between the rod-like object M filled in the filling member 1 and the piston 7 inserted in the filling member 1. The rod-like object M does not appear reliably from the filling member 1.

  Moreover, since the air vent groove 1i which is a ventilation part is provided, the air of the said space Z is escaped favorably through the air vent groove 1i. Further, as described above, since the air in the space Z is released through the air vent groove 1i, the filling member 1 and the main body cylinder 3 are relatively rotated in the rewinding direction, and the advanced piston 7 moves backward. The rod-like object M can be easily pulled back in the filling member 1 as the piston 7 moves backward by the pressure reducing action (keeping in a sealed state) in the filling member 1.

  Further, in the rod-like product extrusion container 100 of the present embodiment, the spring portion 11y of the intermediate member 11 on the main body cylinder 3 side elastically presses the rotating member 10 on the filling member 1 side in the axial direction rearward. Therefore, the filling member 1 and the main body cylinder 3 are rotated relative to each other with a good sliding resistance. The spring portion 11y may not be provided as described above.

  If the inner circumferential surface of the filling member 1 is tapered (tapered) gradually toward the tip side, a particularly soft rod-shaped object can be held, and the rod-shaped object M will fall out even if there is an external impact during storage. This is preferable because it is prevented and kept safe.

  Furthermore, according to the rod-like product extrusion container 100 of the present embodiment, the following effects can be obtained. That is, when the filling member 1 and the main body cylinder 3 are relatively rotated in the rewinding direction, the movable body 6 at an arbitrary position advanced moves backward by a certain amount and stops, in other words, moves backward beyond a certain amount. Therefore, it is possible to prevent the mobile body 6 from returning too much, so that the rod-like object M does not readily appear from the opening 1a at the next use, and the usability (ease of use) is improved.

  Further, when the filling member 1 and the main body cylinder 3 are relatively rotated in the feeding direction and the screwing of the first screwing portion 8 is released, the first screwing is performed by the biasing force of the spring portion 10y of the rotating member 10. Since the joint portion 8 is configured to be screwed back, when the filling member 1 and the main body cylinder 3 are relatively rotated in the rewinding direction, the screwing action of the first screw portion 8 works without any trouble, and the moving body 6 is set to retreat. In addition, when the relative rotation in the feeding direction is continued, the screw release of the first screwing portion 8 and the screwing return by the spring portion 10y are repeated. The degree of relative rotation and the degree of movement of the moving body 6 are perceived by the user.

  The movable body 6 has a male screw 6 b that is one of the second screwing portions 9, and the female screw 5 d of the moving screw cylinder 5 that is the other of the second screwing portions 9 is connected to the rotating member 10. Is biased in the screwing return direction of the first screwing portion 8 by the spring portion 10y that is the biasing means, and the rod-like object M is slidably brought into sliding contact with the inner peripheral surface of the filling member 1 at the tip of the moving body 6. Since the piston 7 for pushing out is mounted and the movable body 6 is movable by a predetermined amount with respect to the piston 7 in the axial direction, the movable body 6 is located when the first screwing portion 8 is released. Is moved by a predetermined amount in the axial direction by the urging force of the spring portion 10y without receiving sliding resistance between the piston 7 and the inner peripheral surface of the filling member 1, whereby the first screwing portion 8 is smoothly moved. In addition, the screwing can be satisfactorily restored.

  In addition, since the lead of the first screwing portion 8 is made larger than the lead of the second screwing portion 9, when the filling member 1 and the main body cylinder 3 are relatively rotated in the feed-out direction, they move. The body 6 quickly advances in accordance with the large (coarse) lead of the first screwing part 8 and the space Z is immediately lost, and the relative rotation in the feeding direction is continued and the screwing of the first screwing part 8 is released. Then, the moving body 6 slowly advances in accordance with the small (fine) lead of the second screwing portion 9 and the rod-like object M appears appropriately from the opening 1a at the tip of the container and is put into use. When the filling member 1 and the main body cylinder 3 are relatively rotated in the retraction direction, the moving body 6 is quickly retracted according to the large lead of the first screwing portion 8, and as a result, the usability (ease of use) is further increased. Has been improved.

  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.

  Here, instead of the air vent groove 1i which is the vent portion, an air vent groove may be provided on the outer surface of the piston 7 as the vent portion.

  Further, as shown in FIG. 20, instead of the air vent groove 1i that is the ventilation portion, a hole 1k that communicates the inside and the outside of the filling member 1 may be adopted as the ventilation portion. Even in this case, from the initial state shown in FIG. 20, that is, from the state where the air vent hole 1k is opened to vent the air in the space Z, the piston 7 is indicated by a virtual line while sliding inside the filling member 1. Thus, by moving forward by a predetermined amount, the air in the space Z is well escaped to the outside of the filling member 1 through the air vent hole 1k, the space Z is immediately eliminated, the ventilation of the air vent hole 1k is closed, and the piston 7 and The rod-like object M is in an airtight contact with the filling member 1.

  Further, as shown in FIG. 21, a hole 7m that communicates the rod-like object M side of the piston 7 and the moving body 6 side may be adopted as the ventilation portion instead of the air vent groove 1i that is the ventilation portion. Even in this case, the piston 7 moves forward by a predetermined amount while sliding in the filling member 1 from the initial state shown in FIG. 20, that is, the state where the air vent hole 7 m is opened to release the air in the space Z. As a result, the air in the space Z is favorably released to the moving body 6 side through the air vent hole 7m, and the space Z is immediately eliminated, the ventilation of the air vent hole 7m is closed, and the piston 7 and the rod-shaped object M are filled with each other. 1 is in an airtight state.

  Note that the relative rotation operation of the filling member 1 and the main body cylinder 3 that moves the piston 7 forward by a predetermined amount to release the air in the space Z and eliminates the space Z may be performed after purchase by the user as described above. Moreover, after assembling the rod-like product extrusion container 100, it may be performed in a factory.

  Here, in the ventilation portions 1i, 1k, and 7m, the ventilation is opened in order to allow the air in the space Z to escape while the filling member 1 is mounted, and the piston 7 is advanced by a predetermined amount by a relative rotation operation. However, as shown in FIG. 22, when the filling member 1 is mounted, a gap between the rod-like object M filled in the filling member 1 and the piston 7 inserted in the filling member 1 is used. In order to allow the air to escape, the air vent may be opened to allow air to escape when the filling member 1 is mounted, and the air vent hole 7n that closes the air flow when the mounting of the filling member 1 is completed may be used as the air vent. In the air vent hole 7n, when the filling member 1 is mounted, that is, when the piston 7 is inserted into the filling member 1, the rod-like object M filled in the filling member 1 and the filling member 1 are inserted. When the air between the piston 7 escapes to the moving body 6 through the air vent hole 7n and the mounting of the filling member 1 is completed, the air vent hole 7n is blocked by the rod-like object M as shown in FIG. Closed and in equilibrium. In this way, when the filling member 1 is mounted, in order to allow air between the rod-like object M filled in the filling member 1 and the piston 7 inserted into the filling member 1 to open, the ventilation is opened. The ventilation portion that closes the ventilation when the mounting of the member 1 is completed can also be configured by the air vent groove 1i or the air vent hole 1k.

  Incidentally, the space Z may be completely lost as shown in FIGS. 2 and 19 after the air is completely released by the ventilation portion. Further, as shown in FIG. Some may remain on the inner periphery.

  FIG. 23 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. 23, a filling material extruding container 200 includes a filling member 101, and a main body that interlinks the filling member 101 with a 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.

  Then, the filling material extruding container 200 can be rotated synchronously with the operation tube 103 and the rod-like material M filled from the front end to the rear end in the filling member 101 in the same manner as in the first embodiment. A screw cylinder 104 that is connected so as not to move in the axial direction, and a moving screw cylinder that engages with the main body cylinder 102 so as to be able to rotate synchronously and move in the axial direction and is screwed into the screw cylinder 104 via the first screwing portion 108. 105, a movable body 106 engaged with the operation cylinder 103 so as to be capable of synchronous rotation and axial movement, and screwed into the moving screw cylinder 105 via a second threaded portion 109, and a distal end portion of the movable body 106 And a piston (extrusion part) 107 inserted into the rear end part of the filling member 101.

  According to this filling 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 screwing projection 105e of the moving screw tube 5 and the female tube 104 are female. The screwing action of the first screwing portion 108 constituted by the screw 104d is activated, and the rotation of the moving screw cylinder 105 constituted by the rear half portion 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 advances along with the moving screw cylinder 105 and simultaneously advances alone.

  Here, when the space Z is formed between the piston 107 and the rod-shaped object M as described in the first embodiment in the filling extrusion container 200 in the initial state, the space Z is The piston 107 and the rod-like object M are hermetically sealed in the filling member 101 by the air vent hole (vent) 107m of the piston 107 at the tip of the moving body 106 that moves forward as the moving screw cylinder 105 advances. It will be in contact.

  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 in 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

  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.

  When the moving body 106 is retracted, the piston 107 and the rod-like object M are in airtight contact with each other in the filling member 101 as described in the first embodiment. Due to the internal pressure reducing action, the rod-like object M is pulled back in the filling member 101 and retreats.

  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 to fill the middle 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 bar is cooled and solidified to become the bar M, the tip side of the main assembly is extrapolated from above with respect to the filling member 101 filled with the bar 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.

  According to such a rod-like product extrusion container 200, since only the filling member 101 is filled with the rod-like material M, the thickness of the filling member 101 is relatively uniform and the thickness of the rod-like material M in the radial direction is in the axial direction. It is possible to stabilize the temperature conditions from filling the molten rod-like material to solidifying. Therefore, it is possible to satisfactorily fill the rod-like object M, and the manufacturing yield is improved. In addition, since the filling member 101 filled with the rod-like object M is assembled to the main assembly (container), manufacturing is facilitated. Further, since the rod-like object M is filled from the front end to the rear end of the filling member 101, the rod-like object M is pushed out by the piston 107 and filled when the filling member 101 is attached to the main assembly. It is prevented from appearing from the member 101, and there is no need for finishing or the like, and the manufacture is facilitated.

  Further, since the air vent hole 107m which is a ventilation portion is provided, when there is a space Z between the rod-like object M and the piston 107, the air in the space Z can escape well through the air vent hole 107m. It has become. In addition, as a structure of a ventilation | gas_flowing part, you may employ | adopt the other ventilation | gas_flowing parts 1i, 1k, etc. which were demonstrated in 1st embodiment, and also employ | adopt the ventilation | gas_flowing part 7n etc. which were described in 1st embodiment, and a filling member The air between the rod-like object M filled in the filling member 101 and the piston 107 inserted into the filling member 101 may be released when the mounting of the body 101 on the main body side assembly is completed.

  Further, in this embodiment, the rod-like object M is formed after the molten rod-like material is filled into the filling member 101 and cooled and solidified, but the opening 101a at the tip of the filling member 101 has a cylindrical hole ( Since it is narrower than the cylindrical hole of the filling member 101, a particularly soft rod-shaped object can be held, and even if there is an external impact during storage, the rod-shaped object M is prevented from falling off and is safely held. 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. 24 is a longitudinal sectional view showing a rod-like product extrusion container according to the third embodiment of the present invention, and FIG. 25 is an enlarged view of part A in FIG. As shown in FIG. 24, the rod-like object feeding 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 the 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 filling extrusion container 300 comprises the connection member 252 for connecting the front cylinder 253 to the main body cylinder 251 so that it can be relatively rotated and cannot move in the axial direction, and an anti-rotation portion (anti-rotation 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, rod-like object M filled halfway from the front end to the rear end in the pipe member 254 in the same manner as in the above embodiment, and advance / retreat as the pipe member moving body 205 advances / retreats. When the pipe member 254 reaches the forward limit and the main body cylinder 251 and the front cylinder 253 are further rotated relative to each other in the feeding direction, the pipe member 254 reaches the backward limit and the main body cylinder 251 When the cylinder 253 is further rotated in the retraction direction, the rod-like object moving body (moving body) 256 moves backward, and the rod-like object moving body 256 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. The piston (extrusion part) 256x, the first screwing part 258 enabling the movement of the pipe member moving body 205, and the second screwing part 259 enabling the movement of the rod-like object moving body 256. And roughly.

  In this rod-shaped object feeding container 300, the first threaded portion 258 is constituted by the threaded projection 205 e of the pipe member moving body 205 and the spiral groove 253 i of the front tube 253, and the female thread of the pipe member moving body 205 is formed. 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 this embodiment, the screwing action of the first screwing part 258 is increased by making the lead of the first screwing part 258 larger than the lead of the second screwing part 259. The second screwing portion 259 works before the screwing action. Incidentally, the operating resistance of the second screwing portion 309 is increased as compared with the first screwing portion 258 by changing the material, for example, and thereby 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 filling extruding container 300, in the initial state, as shown in FIGS. 24 and 25, the pipe member 254 and the pipe member moving body 205 are in a state of reaching 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-like object moving body 256 is fed out in cooperation with the rotation preventing portion 270, and the rod-like object M appears from the pipe member 254 to be used.

  Here, when the space Z is formed between the piston 256x and the rod-shaped object M as described in the first embodiment in the filler extrusion container 300 in the initial state, the first embodiment By adopting the ventilation portions 1i, 1k, 7m, etc., which are substantially the same as described in the above, the space Z can be eliminated by the advancement of the rod-like object moving body 256 by the relative rotation operation, and the piston 256x and the rod-like object M are eliminated. Are in an airtight state in the pipe member 254.

  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 moves backward with the rod-like object moving body 256.

  Here, since the piston 256x is in close contact with the inner peripheral surface of the pipe member 254, the piston 256x is retracted with the pipe member 254, and the piston 256x and the piston 256x are similar to those described in the first embodiment. Since the rod-like object M is in airtight contact with the pipe member 254, the rod-like object M is pulled back and retracted in the pipe member 254 by the pressure reducing action in the pipe member 254, and the pipe member 254 and the rod-like object The tip of the 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 moved backward by the cooperation of the anti-rotation portion 270. At this time, since the piston 256x and the rod-like object M are in airtight contact with each other in the pipe member 254, the rod-like object M moves backward together with the piston 256x, and the tip of the rod-like object M is also accommodated in the pipe member 254. Will be.

  In this state, when the user rotates the main body cylinder 251 and the front cylinder 253 relative to each other in the extending direction, the screwing action of the first screwing portion 58 works, and the pipe member 254 including the rod-shaped object moving body 256. Advances until the screwing action of the first screwing portion 58 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 end of the pipe member 254 is filled to the end, and there is no space in the tip of the pipe member 254, and the molten rod-like object is cooled and solidified to become the rod-like object M, the pipe member 254 filled with the rod-like object M 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.

  According to such a rod-like material extrusion container 300, since only the pipe member 254 is filled with the rod-like material M, the thickness of the pipe member 254 is relatively uniform and the thickness of the rod-like material M in the radial direction is the axial direction. It is possible to stabilize the temperature conditions from filling the molten rod-like material to solidifying. Therefore, it is possible to satisfactorily fill the rod-like object M, and the manufacturing yield is improved. In addition, since the pipe member 254 (the leading tube 253) filled with the rod-like object M is assembled to the main assembly (container), manufacturing is facilitated. Further, since the rod-like object M is filled halfway from the front end to the rear end of the pipe member 254, the rod-like object M is pushed out by the piston 256x when the pipe member 254 is attached to the main assembly. It is prevented from appearing from the member 254, and there is no need for finishing or the like, and manufacturing is easy.

  In addition, the rod-like object M filled in the pipe member 254 and the pipe member 254 are used when the mounting of the front tube 253 containing the pipe member 254 to the main body side assembly is adopted by adopting the ventilation portion 7n described in the first embodiment. You may make it escape the air between piston 256x inserted in.

  FIG. 26 is a longitudinal sectional view showing an initial state of the rod-like product extrusion container according to the fourth embodiment of the present invention, and FIG. 27 is a state where the moving screw cylinder and the moving body are advanced by a user operation from the state shown in FIG. It is a longitudinal cross-sectional view at the time. As shown in FIG. 26, the filling extruding container 400 is rotated relative to the main body cylinder 31 via 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.

  And this rod-shaped object extrusion container 400 includes a pipe member (filling member) 304 and a rod-shaped object M filled from the front end to the rear end in the pipe member 304 in the same manner as in the first embodiment. The pipe member 304 is connected so as to be synchronously rotatable and cannot be detached in the axial direction, and the female screw member 305 that moves forward / backward when the main body cylinder 301 and the front cylinder 303 are rotated relative to each other; A rotating member 316 that is movably engaged and moves forward / backward as the female screw member 305 moves forward / backward, and is engaged with the rotating member 316 so as to be able to rotate synchronously and move in the axial direction, and the female screw member 305 moves forward / backward. Accordingly, the movable body 306 moves forward when the pipe member 304 reaches the forward limit and the main body cylinder 301 and the front cylinder 303 are further rotated relative to each other in the same direction. A piston (extrusion part) 307 attached to the end part and inserted into the rear end part of the pipe member 304, a first screwing part 308 that enables the female screw member 305 to move, and a movable body 306 can be moved. And a second threaded portion 309.

  In this rod-like material extruding container 400, a first threaded portion 308 is constituted by the threaded projection 305 e of the female threaded member 305 and the threaded groove 303 b of the front tube 303. 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 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.

  According to this filler extruding container 400, when the main body cylinder 301 and the front cylinder 303 are relatively rotated in the pay-out direction from the initial state shown in FIG. The moving body 306 and the piston 307 are moved forward together with the female screw member 305 and the pipe member 304 in cooperation with the rotation preventing portion 350, and the distal end portion of the pipe member 304 appears from the opening at the distal end of the front tube 303.

  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. 27, as shown in FIG. 27, 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 thereof. 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 extending 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 moves forward, 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.

  Here, as described in the first embodiment, when the space Z is formed between the piston 307 and the rod-like object M, the ventilation portions 1i, which are substantially the same as those described in the first embodiment. By adopting 1k, 7m, etc., the space Z can be eliminated by advancing the piston 307 by a relative rotation operation, and the piston 307 and the rod-like object M are in an airtight contact state in the pipe member 304.

  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. And the pipe member 304 is retracted and the moving body 306 and the piston 307 are retracted, the leading end portion of the pipe member 304 is immersed from the opening at the leading end of the leading 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 When the female screw member 305 reaches the retreat limit and the screwing action of the first screwing portion 308 stops and the main body tube 301 and the front tube 303 are subsequently relatively rotated in the retraction direction, The screwing action of the second screwing part 309 works, and the movable body 306 and the piston 307 are moved backward by cooperation with the rotation preventing part 350.

  At this time, since the piston 307 and the rod-like object M are in airtight contact with each other in the pipe member 304, the rod-like object M moves backward together with the piston 307, and the leading end portion of the rod-like object M has the leading tube 303 and the pipe member 304. Housed inside.

  As an assembly procedure of such a rod-like material extruding container 400, the first and second screwing portions 308 and 309 are arranged in the main body side cylinder formed of the main body cylinder 301, the front cylinder pressing member 302, and the front cylinder 303. , An extrusion mechanism including a rotation preventing portion 350, a female screw member 305, a rotating member 316, a moving body 306, and a piston 307 are provided (incorporated) to obtain a main body side assembly.

At this time, the inner peripheral surface of the pipe member 304 is engaged with the female screw member 305 while being in sliding contact with the annular protrusion 307 c for ensuring the airtightness of the piston 107.

  According to such a rod-like material extrusion container 400, only the pipe member 304 is filled with the rod-like material M, so that the thickness of the pipe member 304 is relatively uniform and the thickness of the rod-like material M in the radial direction is in the axial direction. It is possible to stabilize the temperature conditions from filling the molten rod-like material to solidifying. Therefore, it is possible to satisfactorily fill the rod-like object M, and the manufacturing yield is improved. In addition, since the pipe member 304 filled with the rod-like object M is assembled to the main assembly (container), manufacturing is easy. Further, since the rod-like object M is filled halfway from the front end to the rear end of the pipe member 304, the rod-like object M is pushed out by the piston 307 when the pipe member 304 is attached to the main assembly. It is prevented from appearing from the member 304, and there is no need for finishing or the like, and manufacturing is easy.
