[0004]

[Problems to be solved by the device]

 However, in the case of a rod-shaped object feeding container of the type described in Japanese Utility Model Laid-Open No. 1-59692, the spiral pin is formed on the inner surface of the tubular cap, so that the core pin is rotated while the core pin is rotated at the time of forming the groove. There is a problem that it has to be removed, the manufacturing time is long, and the cost cannot be reduced.

On the other hand, in the case of a rod-shaped material feeding container of the type described in Japanese Utility Model Laid-Open No. 63-108785, the length of the screw member, which is a male screw, is required, so that the entire length of the container becomes long, or There is a problem that the rod-shaped object must be shortened. The present invention has been made in view of the above problems, and an object of the present invention is to provide a rod-shaped product feeding container that can shorten the manufacturing time and can make the length of the rod-shaped product sufficiently long.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a rod-shaped object feeding container according to the present invention comprises an outer cylinder, a guide cylinder rotatably fitted in the outer cylinder and extending in the axial direction, a guide cylinder having a male screw on the outer periphery, and the guide cylinder. And a rod-shaped object holder that holds the rod-shaped object and has an engaging portion that slidably engages with the guide slit and is axially immovable with respect to the engaging portion of the rod-shaped object holder. A female screw member that is rotatably mounted and is non-rotatably mounted so as to be movable in the axial direction with respect to the outer cylinder, and that has an inner thread having a female thread that is screwed with the male thread of the guide cylinder.

Further, the guide cylinder may include a rotary knob portion axially protruding from the outer cylinder.

[0008]

[Action]

 When the guide cylinder is rotated with respect to the outer cylinder, the guide cylinder rotates with respect to the female screw member that is made non-rotatable by the outer cylinder, and the female screw member is screwed with the male screw of the guide cylinder. Moves in the axial direction. Then, since the female screw member and the rod-shaped object holder which is immovable in the axial direction move in the axial direction together with the female screw member, the rod-shaped object can be projected from the tip of the outer cylinder. In addition, when it is rotated in the opposite direction, the rod-shaped object sinks.

Since the male screw is provided on the outer periphery of the guide tube and the length of the female screw portion screwed to the male screw may be short, the manufacturing thereof is simplified. That is, it is not necessary to rotate the core pin at the time of molding as in the conventional case, so that the manufacturing cost can be reduced. In addition, since the rod-shaped object can be present inside the guide tube and the space for the rod-shaped object is not occupied by the male screw, the length of the rod-shaped object can be made sufficiently longer than in the conventional case.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In the following examples, the stick-shaped object feeding container will be described as an example in which it is connected to the rear portion of the mechanical pencil, but the present invention is not limited to this, and it can be combined with an object other than a writing instrument such as a mechanical pencil or a ballpoint pen, or alone. It can also be used.

The rod-shaped material feeding container 10 mainly includes an outer cylinder 12, a guide cylinder 14, a rod-shaped material holder 16, and a female screw member 18. The outer cylinder 12 is a cylindrical body whose inner circumference is polygonal (octagonal in this embodiment), and an annular projection 13 is provided in front of the inner circumference thereof. The annular protrusion 13 has a taper formed on the rear side.

As shown in FIG. 2, the guide cylinder 14 has an annular stopper 26 at its rear end and a projecting piece 27 which can be bent in the radial direction at the front, and is provided with respect to the outer cylinder 12. By inserting the guide tube 14 from the rear side, the protruding piece 27 bends inward according to the taper of the annular protrusion 13, and the protruding piece 27 returns again beyond the annular protrusion 13 and contacts the annular protrusion 13. Therefore, the guide cylinder 14 is rotatably fitted into the outer cylinder 12 by the annular stopper 26 and the protruding piece 27 so as to be immovable in the axial direction. The guide cylinder 14 has two guide slits 22 extending in the axial direction between the projecting piece 27 and the annular stopper 26. The extension of the guide slit 22 serves as a groove inside the annular stopper 26, and It extends to the end. A spiral groove, which is a male screw 24, is formed on the outer circumference of the guide cylinder 14. Further, the tip 28 of the guide tube 14 is formed in a polygonal shape so as to be non-rotatably fitted to a tip shaft 60 of a mechanical pencil described later.

As shown in FIG. 3, the rod-shaped object holder 16 includes a holder body 29 and two engaging portions 30 that slidably engage with the two proposed slits 22. The engaging portion 30 is provided with a claw 31 for holding the rod-like object 20 on the inner surface of its tip and two protrusions 32 for accommodating the female screw member 18 on its outer surface. However, the holding of the rod-shaped object does not necessarily have to be performed by the engaging portion 30, and the rod-shaped object 20 may be inserted into the cylindrical holder main body 29. A slit 34 penetrating in the axial direction is formed in the holder body 29, and the rod-shaped object holder 16 is bent inward by utilizing the slit 34 during assembly, so that the rod-shaped object holder 16 is guided from the guide slit 22 of the guide tube 14. The engaging portion 30 can be engaged with the guide slit 22 by inserting.

As shown in FIG. 4, the female screw member 18 has a polygonal outer periphery that is slidable on the inner periphery of the polygon of the outer cylinder 12, and the inner periphery of the female screw member 18 has a female screw portion of about a half pitch. 36 is formed. The female screw member 18 passes through the tip 28 of the guide tube 14 into which the rod-shaped object holder 16 is already inserted at the time of assembly, and removes the projecting piece 27 that can be bent inward to remove the guide tube 14 from the guide tube 14. The male screw 24 and the female screw 36 are screwed together. Further, the rod-shaped object holder 16 is bent inward by utilizing the slit 34, so as to pass through one of the protrusions 32 and be accommodated between the protrusions 32. By inserting the guide cylinder 14, the rod-shaped object holder 16, and the female screw member 18 assembled in this way from the rear of the outer cylinder 12 as described above, the rod-shaped product feeding container 10 is assembled and the multi-threaded member 18 is inserted. The outer periphery of the prism is slidably attached to the inner periphery of the polygon of the outer cylinder 12. The outer circumference of the female screw member 18 and the inner circumference of the outer cylinder 12 may have a relationship of a key groove and a key instead of a polygonal shape.

The tip 28 of the guide cylinder 14 is fitted to a polygon formed on the inner surface of the rear end of the front shaft 60 of the mechanical pencil 56, and is non-rotatably attached. The relationship between the tip 28 and the front shaft 60 may be the relationship between the key groove and the key. The mechanical pencil 56 constitutes a known side-knock type mechanical pencil, that is, a knock lever 62 having a U-shaped base end is attached to an opening formed in a side surface of the tip shaft 60, and the mechanical pencil 56 is provided inside the tip shaft 60. Is provided with a slider 64 which is biased rearward by a spring 66 and is slid forward by a U-shaped base end of a knock lever 62. Further, the slider 64 is connected to the slider 64, and a chuck 68 and a head of the chuck 68 are provided. A chuck ring 70 that is fitted to the outer periphery of the portion to open and close the chuck 68, and a lead tank 72 extending rearward are arranged.

Next, the operation of this embodiment will be described. When the front shaft 60 is rotated with respect to the outer cylinder 12 (or the outer cylinder 12 is rotated with respect to the front shaft 60), the front shaft 60 and the guide cylinder are rotated. Since 14 is non-rotatable, relative rotation between the outer cylinder 12 and the guide cylinder 14 occurs. Since the female screw member 18 cannot rotate with respect to the outer cylinder 12, the female screw member 18 moves in the axial direction by screwing the female screw 36 of the female screw member 18 and the male screw 24 of the guide barrel 14. Since the female member 18 and the rod-shaped member holder 16 cannot move in the axial direction, the rod-shaped member holder 16 moves in the axial direction together with the female screw member 18 so that the rod-shaped member 20 is looped. It can be projected from the stopper 26.

Further, when rotating in the opposite direction, the rod-shaped object 20 moves in the opposite axial direction, and the rod-shaped object is sunk and stored. According to such a configuration, the male screw 24 is provided on the outer circumference of the guide cylinder 14, and the length of the portion of the female screw 36 screwed to the male screw 24 may be short, so that the manufacturing thereof is simplified. That is, since the female screw 36 of the female screw member 18 may have a length of about a half pitch, by inserting two core pins from both sides of the female screw member 18 at the time of molding, it is not necessary to rotate the core pin at the time of die cutting. The manufacturing cost can be reduced.

Further, since the rod-shaped object 20 can be present inside the guide cylinder 14 provided with the male screw 24, the rod-shaped object 20 having the same overall length as that of the type such as the actual open Sho 63-108785 is provided. The length can be long. Next, FIG. 5 shows a second embodiment of the present invention. The same components as those in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, the rod-shaped object feeding container 10 is connected to a known rear end knock type mechanical pencil 58.

That is, the main difference from the first embodiment is that the outer cylinder 12 is larger than the diameter of the front shaft 60 and slidably overlaps with the front shaft 60, and the outer cylinder 12 and the guide cylinder 14 together. Centering can be performed by knocking forward in the axial direction. The action and effect of the rod-shaped material feeding container 10 are similar to those of the first embodiment. Next, FIG. 6 shows a third embodiment of the present invention, in which the same components as those of the previous embodiment are designated by the same reference numerals and the description thereof is omitted. In this embodiment, the outer cylinder 42 is formed integrally with the tip shaft of the side knock type mechanical pencil 56.

As shown in FIG. 7, the guide cylinder 44 has a rotary knob portion 48 at its rear end and a protrusion 49 in the vicinity of the rotary knob portion 48. The guide cylinder 44 is inserted from the rear side of the outer cylinder 42, the rear end of the outer cylinder 42 abuts on the rotary knob portion 48, and the annular recess 43 and the protrusion provided at a position facing the protrusion 49 of the outer cylinder 42. By the weak engagement of 49, the outer cylinder 42 is detachably and rotatably fitted. Similar to the previous embodiment, the extension of the guide slit 22 extending in the axial direction becomes a groove inside the rotary knob portion 48.

As shown in FIG. 8, the rod-shaped object holder 46 has two engaging portions 54 that engage with the holder main body 53 and the guide slit 22. Two protrusions 55 for accommodating the female screw member 18 are respectively provided in a portion of the engaging portion 54 extending from the holder main body 53. The length of the engaging portion 54 is such that when the rod-shaped object holder 46 moves to the maximum rotation knob portion 48, the engagement portion 54 of the rod-shaped object holder 46 is an inner groove provided in the rotation knob portion 48. It should be selected to project somewhat beyond. The engagement portion 54 protruding from the rotary knob portion 48 facilitates replacement of the consumed rod-shaped object 20. It should be noted that the holder body 53 of the rod-shaped object holder 46 may be provided with the slit 34 similar to that in the previous embodiment, but since the positions of the holder body 53 and the projection 55 are axially displaced, no special slit is provided. Can also be inserted into the guide slit 22.

A funnel-shaped core receiver 74 is attached to the rear end of the core tank 72. In the present embodiment, by rotating the rotary knob portion 48 with respect to the outer cylinder 42, the rod-shaped object 20 can be taken in and out as in the previous embodiment. Further, when the lead is replenished by the mechanical pencil 56 of the present embodiment, the annular recess 43 and the projection 49 are disengaged by pulling the rotary knob portion 48 of the guide tube 44 rearward. Then, the core can be inserted from the rear of the outer cylinder 42. At this time, since there is the core receiver 74, the core is surely replenished in the core tank 72.

Next, FIG. 9 shows a fourth embodiment of the present invention. The same components as those in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, the outer cylinder 42 is configured integrally with the front shaft of the rear end knock type sharp pencil 58. The guide cylinder 50 of this embodiment has a connecting portion 51 at its front end, and the connecting portion 51 has an annular concave portion 52 at its tip to engage with the annular protrusion 75 of the funnel-shaped core bearing 74. . However, the engagement between the guide tube 50 and the core support 74 is set weaker than the engagement between the core support 74 and the core tank 72.

Also in the present embodiment, by rotating the rotary knob portion 48 with respect to the outer cylinder 42, the rod-shaped object 20 can be taken in and out as in the previous embodiment. When the lead is advanced, the rotary knob portion 48 is knocked from the rear side to push the chuck 68 through the connecting portion 51 and the core receiver 74 to perform centering. Further, when the lead is replenished with the mechanical pencil 58 of the present embodiment, the engagement between the connecting portion 51 and the core receiver 74 is disengaged by pulling the rotary knob portion 48 of the guide tube 44 rearward. Then, the core can be inserted from the rear of the outer cylinder 42.

In each of the above-described embodiments, the female screw 36 is shown as a projection for about half a pitch and the male screw 24 is shown as a spiral groove. However, the relationship may be reversed, and the female screw 36 may be a groove with a short pitch, a male screw. 24 may be a spiral protrusion. In this case, the core pin has to be rotated a little when the female screw member 18 is molded, but still, the manufacturing time and labor can be sufficiently reduced as compared with the conventional case.

Further, in each of the above-mentioned embodiments, the spiral groove which is the male screw 24 is illustrated as a single-thread spiral, but it goes without saying that a multi-thread spiral having two or more threads is also within the scope of the present invention. . In that case, a plurality of female screws 36 having a short pitch may be provided, and the manufacturing time and labor can be reduced as compared with the conventional product having the same multi-helix. The multi-strand spiral has the effect of increasing the rotational stability.

[0027]

[Effect of device]

 As described above, according to the present invention, the male screw is provided on the outer periphery of the guide tube, and the length of the female screw portion screwed to the male screw may be short, so that the manufacturing thereof is simplified. Immediately, it is not necessary to rotate the core pin at the time of molding as in the conventional case, so that the manufacturing cost can be reduced.

Further, since the rod-shaped object can be present inside the guide cylinder and the space for the rod-shaped object is not occupied by the male screw, the length of the rod-shaped object can be made sufficiently longer than in the conventional case.
