The present invention relates to a rod-shaped container for allowing a rod-shaped object such as an eraser rubber, a lipstick, a crystal rod, a writing pen, a fluorescent pencil pen, a shape paste, and a paste to be pushed in and out of a container by rotating pieces.

Examples of such rod-shaped container for dispensing are those described in Japanese Patent Application Laid-Open No. 1-59692. This rod-shaped container is axially formed in a cylindrical cap in which a spiral groove having an internal thread is formed. Guide cylinders formed with guide slits are inserted so as to be rotatable without moving in the axial direction, and the guide slits of the guide cylinders are screwed into the spiral grooves and have pinned object holders having protrusions that function as male threads. It has a structure that is fitted to reciprocate through the media.

In addition, writing instruments that are provided with a separate rod dispensing container may be, for example, those described in Japanese Patent Application Laid-Open No. 63-108785, which are moved in the axial direction in the rear cap, but cannot be rotated. The inserted knock cap, the rod holder which is axially moved but cannot rotate in the knock cap, the male screw member screwed in the rod holder, and the outer cylinder of the screw member and the writing instrument is rotated. It has a structure with a connecting member to prevent it from connecting.

However, in the rod-shaped dispensing container of the type described in Japanese Patent Application Laid-Open No. 1-59692, a spiral shaft is formed on the inner surface of the cylindrical cap, and when the spiral groove is formed, the mold must be pulled out while rotating the core pin. For this reason, there is a problem in that it takes a lot of time to manufacture the cap and cannot reduce the manufacturing cost.

On the other hand, in the rod-shaped dispensing container of the type described in Japanese Patent Application No. 63-108785, the male screw member must have a certain length, so that the overall length of the container becomes long or the length of the rod becomes short. There is a problem.

The present invention has been made in view of the above circumstances, the object of the present invention is to provide a rod-shaped container for discharging the container can be shortened, the length of the rod is also sufficiently long.

The present invention for achieving the above object is an outer cylinder, a guide slit inserted to rotate in the outer cylinder and a guide cylinder formed with a male thread on the outer periphery, and fitted into the guide cylinder and reciprocated in the guide slit. A rod holder which holds the rod-shaped object with a locking portion which is engaged to be movable, and is attached so as to be able to rotate only without moving in the axial direction with respect to the hook portion of the rod-shaped holder while being axial in the outer cylinder. It is attached so as not to rotate but can be rotated, the female screw threaded to the male screw of the guide cylinder has a structure having a female screw member formed on the inner peripheral surface.

Here, the guide cylinder may be provided with a rotary knob protruding in the axial direction from the outer cylinder.

Therefore, when the guide cylinder is rotated with respect to the outer cylinder, the guide cylinder is rotated with respect to the female screw member installed so as not to rotate in the outer cylinder, the female screw member and the male screw thread grooves of the guide cylinder are screwed, the female screw member moves in the axial direction Done. And because the rod holder coupled to the female screw member so as not to move in the axial direction moves in the axial direction together with the female screw member, the rod is protruded from the front end of the outer cylinder, and when rotated in the opposite direction, the rod can be attracted. do.

In addition, since the male thread is formed on the outer circumference of the guide cylinder and the length of the female threaded portion screwed to the male thread is short, the manufacturing becomes simple, i.e., there is no need to rotate the core pin during molding as in the prior art. Manufacturing costs can be much lower.

In addition, the rod-shaped object can be positioned inside the guide cylinder, and the space for the rod-shaped object is not occupied by the male screw, so that the rod-shaped object can be much longer than the conventional one.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a partial cross-sectional view showing a first embodiment of the present invention, in the following embodiment will be described an example in which all the rod-shaped material dispensing container is coupled to the rear portion of the mechanical pencil, but is not limited thereto. Of course, in addition to writing instruments such as mechanical pencils and ballpoint pens may be combined with the article or used alone.

The rod-shaped container for dispensing the first embodiment of the present invention has a structure having an outer cylinder 12, a guide cylinder 14, a rod holder 16, and a female screw member 18, among which an outer cylinder 12 ) Is a cylindrical body having an inner circumferential surface in the shape of a polygon (octagonal in this embodiment), and an annular projection 13 is formed in front of the inner circumferential surface. This annular projection 13 is formed with a tapered surface toward the back.

As shown in FIG. 2, the guide cylinder 14 is provided with an annular stopper 26 at its rear end and a protruding piece 27 which can be bent in the radial direction at the front thereof. When the guide cylinder 14 is inserted from the rear side with respect to the outer cylinder 12, the protruding piece 27 is bent inward along the tapered surface of the annular protrusion 13 to cross the annular protrusion 13 and then protrude again. (27) returns to its original state and comes into contact with the annular projection (13).

Therefore, the guide cylinder 14 is fitted so that it can only rotate without the axial movement with respect to the outer cylinder 12 by the annular stopper 26 and the protrusion piece 27. As shown in FIG.

In addition, the guide cylinder 14 is provided with two guide slits 22 extending axially between the protruding piece 27 and the annular stopper 26, and the extension portions of these guide slits 22 are annular stoppers ( In 26), a groove is formed on the inner surface to extend to the rear end of the annular stopper 26. The outer circumference of the guide cylinder 14 is formed with a spiral groove made of a male screw 24, while the front end 28 of the guide cylinder 14 is polygonal to fit the mechanical pencil 60 to be rotated later described Formed.

In addition, the rod-shaped holder 16 has a structure having two locking portions 30 that are engaged to slide the holder body 29 and the two guide slits 22, as shown in FIG. These locking portions 30 are provided with a locking piece 31 for holding the rod 20 on the inner surface of the front end portion thereof while the two projections for accommodating the female screw member 18 on the outer surface thereof. 32).

Here, the retaining of the rod-shaped article does not necessarily have to be made by the locking portion 30, that is, the rod-shaped article 20 may be inserted into the holder body 29 having a cylindrical shape. The holder body 29 is formed with a slit 34 penetrated in the axial direction, and the slit 34 is used at the time of assembly so that the rod-shaped object holder 16 is bent inwardly, so that the guide cylinder ( The rod-shaped object holder 16 is inserted from the guide slit 22 of 14 so that the locking portion 30 can be engaged with the guide slit 22.

As shown in FIG. 4, the female screw member 18 has a polygonal outer circumferential surface which is capable of sliding reciprocating the polygonal shape of the outer cylinder 12 on one inner circumferential surface, while having approximately 1/2 on the inner circumferential surface thereof. A female screw 36 corresponding to the pitch is formed. Therefore, when assembling this female screw member 18, the guide cylinder 14 into which the rod-shaped holder 16 is fitted is inserted through the front end portion 28 of the guide cylinder 14 and then bent inwardly. After passing through the protruding piece 27, the female screw 36 formed therein is inserted into the male screw 24 of the guide cylinder 14, thereby screwing.

Then, by using the slit 34 to bend the locking portions 30, 30 of the rod holder 16 inwards and beyond one projection 32, the female screw member 18 between the projection 32 and the projection 32 ) To be accommodated.

When the guide cylinder 14, the rod holder 16, and the female screw member 18 assembled in this way are inserted from the rear of the outer cylinder 12 as described above, the assembly of the rod-shaped article container 10 is completed. In this case, the polygonal outer circumferential surface of the female screw member 18 is coupled to the polygonal inner circumferential surface of the outer cylinder 12 so as to slide reciprocately. Here, the outer circumferential surface of the female screw member 18 and the inner circumferential surface of the outer cylinder 12 may be formed in a relationship between the key groove and the key without making a polygonal shape.

In addition, the front end portion 28 of the guide cylinder 14 is fitted with a polygonal upper portion formed on the rear end inner surface of the front cylinder 60 of the mechanical pencil 56 bar, so that also the front end portion 28 and the front It goes without saying that the relationship with the cylinder 60 may be between the key groove and the key.

On the other hand, as the mechanical pencil 56, a mechanical pencil composed of a known axial knock type, that is, a knock lever 62 having a U-shaped proximal end is attached to the opening formed in the side surface of the front outer cylinder 60. In the front outer cylinder 60, a slider 64 which is pushed backward by the spring 66 and is slid forward by the U-shaped upper end of the knock lever 62 is disposed, and this slider 64 The chuck 68 is connected to the chuck 68 and the chuck ring 70 is inserted into the outer periphery of the head portion of the chuck 68 so as to open and close the chuck 68, and the pen center tank 72 extending backward.

Next, the operation of the first embodiment configured as described above will be described.

When the front outer cylinder 60 is rotated with respect to the outer cylinder 12 (or the outer cylinder 12 may be rotated with respect to the front outer cylinder 60). Since the front outer cylinder 60 and the guide cylinder 14 is prevented from rotating, the outer cylinder 12 and the guide cylinder 14 rotate relatively. In addition, the female screw member 18 is also prevented from rotating with respect to the outer cylinder 12. Therefore, the female screw member 18 is formed by screwing the female screw 36 of the female screw member 18 and the male screw 24 of the guide cylinder 14. Moves in the axial direction.

On the other hand, since the movement in the axial direction cannot be made between the female screw member 18 and the rod-shaped holder 16, the rod-shaped holder 16 moves in the axial direction together with the female screw member 18. As a result, the rod-shaped article 20 protrudes from the annular stopper 26. In addition, when rotated in the reverse direction, the rod-like article 20 is moved in the axial direction to the opposite side, so that the rod-like article is collected and accommodated.

According to such a structure, since the male screw 24 is formed in the outer peripheral surface of the guide cylinder 14, and the length of the female screw 36 part screwed to the male screw 24 may be short, it becomes easy to manufacture. That is, since the female screw 36 of the female screw member 18 may have a length of about 1/2 pitch, it can be removed from the mold only by inserting two core pins from both sides of the female screw member 18 during molding. This eliminates the need to rotate the core pins, resulting in lower manufacturing costs.

In addition, the rod-shaped article 20 can be accommodated in the guide cylinder 14 having the male screw 24 formed therein, so that the guide cylinder has the same length as the one described in Japanese Patent Application No. 63-108785. The length of the rod-shaped object 20 accommodated in the can be made longer.

In the second embodiment, the rod-shaped object dispensing container 10 is combined with a known rear-end knock-type mechanical pencil 58. That is, the second embodiment differs from the first embodiment by the outer cylinder 12. It overlaps and is coupled to the front outer cylinder 6 which has a diameter larger than the diameter of this front outer cylinder 6 so that a sliding reciprocation may be carried out, and the said outer cylinder 12 and the guide cylinder 14 will be axially forward-knocked together, and the core will be drawn out. Is to make it possible. The action and effect of the rod-shaped object dispensing container 10 in the second embodiment configured as described above are the same as those in the first embodiment.

6 is a cross-sectional view of a third embodiment of the present invention, in which the same components as in the first and second embodiments are denoted by the same reference numerals, and description thereof will be omitted. .

In the third embodiment. The outer cylinder 42 is integrally formed with the front outer cylinder of the axial knock mechanical pencil 56, that is, the guide cylinder 44 is rotated behind the guide cylinder 44 as shown in FIG. In this configuration, the projection 49 is formed in the vicinity of the rotation knob 48.

In addition, the guide cylinder 44 is inserted from the rear of the outer cylinder 42 so that the rear end of the outer cylinder 42 is in contact with the rotation knob 48, and in the position facing the projection 49 of the outer cylinder 42 The formed annular concave portion 43 and the protrusion 49 are engaged with each other so as to be detachable with respect to the outer cylinder 42 while being rotatably fitted. In addition, in the third embodiment, as in the previous embodiment, the extension portion of the guide slit 22 extending in the outgoing direction forms a groove on the inner surface of the rotary knob 48.

And the rod-shaped holder 46 in the third embodiment has two engaging portions 54 that are engaged with the holder body 53 and the guide slit 22, as shown in FIG. Two projections 55 for accommodating the female screw member 18 are formed at portions extending from the holder body 53 of the locking portion 54, respectively. Here, the length of the locking portion 54 is a groove formed in the inner surface of the rotating handle 48 of the locking portion 54 of the rod holder 46 when the rod holder 46 is moved toward the rotation knob 48 as much as possible. It's a good idea to determine how much you can project beyond.

Therefore, the locking portion 54 can protrude from the rotary knob 48, so that the remaining rod-shaped article 20 can be easily replaced. In addition, the holder body 53 of the rod-shaped holder 46 may be formed with a slit 34 as in the previous embodiment, but the positions of the holder body 53 and the protrusion 55 are to be deviated from each other on the shaft. Therefore, even if the slit is specially formed, it can be inserted into the guide slit 22. At the rear end of the pen core tank 72, a pen core support portion 74 having a funnel shape is attached. In this embodiment, by rotating the rotary knob 48 with respect to the outer cylinder 42 it is possible to enter and exit the rod-like object 2 as in the previous embodiment.

In order to supplement the core with the mechanical pencil 56 according to the third embodiment of the present invention, by pulling the rotation knob 48 of the guide cylinder 44 to the rear, the hooking of the annular concave portion 43 and the protrusion 49 is peeled off. After inserting, the core is inserted from the back of the outer cylinder 42. In this case, since the lead support unit 74 is provided, the lead is surely replenished with the lead tank 72.

9 is a partial cross-sectional view of a fourth embodiment of the present invention. The same components as in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In the fourth embodiment, the outer cylinder 42 has a structure integral with the front outer cylinder of the rear knock type mechanical pencil 58. In addition, the guide cylinder 50 in this embodiment is provided with a connecting portion 51 at the front end thereof, and is provided with an annular concave portion 52 at the front end of the connecting portion 51, and has a funnel shape 74 having a funnel shape. ) To be aligned with the annular projection (75). Here, the locking of the guide cylinder 50 and the lead support unit 74 is engaged with a weaker force than the engagement of the lead support unit 74 and the lead tank 72.

In this embodiment, when the rotary knob 48 is rotated with respect to the outer cylinder 42, the rod 20 is made to enter and exit as in the previous embodiment, that is, to advance the pen core, the rotary knob 48 When pressed from the back and knocked, the chuck 68 is pressed through the connection portion 51 and the lead support portion 74 to draw the lead.

In addition, when refilling the pencil core to the mechanical pencil 58 according to the present embodiment, the rotary knob 48 of the guide cylinder 44 is pulled backwards so that the engagement of the connecting part 51 and the lead support part 74 is removed. After inserting, the pen core may be inserted from the rear of the outer cylinder 42.

On the other hand, in each of the above embodiments, although the female screw 36 is made of a roughened stone having a pitch of about 1/2 pitch, the male screw 24 is formed as a spiral groove, but it may be the opposite relationship. The female screw 36 may be a short pitch groove, and the male screw 24 may be a spiral protrusion. In this case, the core pin should be slightly rotated when forming the female screw member 18, but the manufacturing time and product can be sufficiently reduced as compared with the related art.

In addition, in each of the above embodiments, the male threaded groove 24 is shown as having a single-threaded thread, but even if it is two or more, it is within the scope of the present invention. Since the female screw 36 should be formed, the manufacturing time and product can be reduced compared to the conventional one having the same number of spiral grooves. In addition, in the case of a multi-layered spiral groove, there is an effect of increasing the safety of rotation.

As described above, according to the present invention, the male screw is formed on the outer circumferential surface of the guide cylinder, and the length of the female screw portion screwed to the male screw may be short, so that the manufacturing becomes simple. Since the pin does not need to be rotated, manufacturing costs can be lowered, and the rod can be stored completely inside the guide cylinder, so that the rod has a much longer length than the conventional one because the space for the rod is not occupied by the male screw. You can lose.
