Description

  The present invention relates to a rod-like object feeding container that causes a rod-like object such as a rod-shaped eraser, lipstick, correction rod, writing core, fluorescent core, rod-like glue, and passes to be raised and lowered by a rotating operation.

  Conventionally, as such a rod-shaped object feeding container, a mechanical pencil having a fitting groove is pivotally attached to the lower part of the main body, and an upper part of the mechanical main body having a spiral groove on the inner surface is rotatably pivoted, and relative to the upper and lower parts of the mechanical pencil body. Insert a core tube having an open slit opened on the head side at the facing position so that its convex part fits into the fitting groove, and core the eraser holder with the protruding part engaged with the spiral groove and the open slit. There has been proposed one in which a rod-shaped eraser is fitted to an eraser receiver provided in a pipe (see, for example, Patent Document 1).

  However, in such a rod-like object feeding container, the rod-shaped eraser can be fed from the head by rotating the upper part of the main body, but the protrusion of the eraser holder reaches the upper end of the spiral groove and stops, and the eraser is fed. When the eraser cannot be used because the eraser cannot be used, the eraser is fitted into the eraser receiver, so that it is extremely difficult to remove the remaining eraser in the eraser receiver.

In order to eliminate this point, the present applicant rotates the inner cylinder having an open slit opened on the head side on the inner surface of the cylindrical cap having an open spiral groove opened at one end on the inner surface so as not to move in the axial direction. Propose a rod-shaped object feeding container that is freely inserted and provided with a rod-shaped object receiving base in the inner cylinder, with a holding piece and a protrusion engaged with an open slit and an open spiral groove, respectively. (For example, refer to Patent Document 2). In the rod-shaped object feeding container having such a structure, when the inner cylinder or the cylindrical cap is rotated with respect to the cylindrical cap or the inner cylinder, the sandwiching piece and the protrusion of the rod-shaped object receiving base are respectively the open slit of the inner cylinder and the cylindrical cap. Since the rod-shaped object holder is guided along the open spiral groove by the open slit and moved in the axial direction, the rod-shaped object held by the holding piece of the rod-shaped object holder rotates. Depending on the direction, it will appear from the tip of the cylindrical cap. In such a rod-shaped object feeding container, when the rod-shaped object is consumed and used as a remaining part, the holding piece of the rod-shaped object receiving base can be protruded from the tip of the cylindrical cap. It is possible to remove the remaining bar-like material very easily.
Japanese Utility Model Publication No. 57-132598 (FIG. 1) Utility Model Registration No. 2549741 (Scope of Utility Model Registration Request, Fig. 1)

  However, in the conventional bar-shaped object feeding container, the holding pieces of the bar-shaped object receiving base are engaged with the open slits of the inner cylinder, so the number and size of the holding pieces are limited by the number of open slits and their width dimensions. However, there remains a defect that limits the degree of freedom of the design.

The pair of opposed pieces is erected on the second slider, and the pair of opposed pieces opens at a predetermined distance from the receiving part so that the tip is expanded by the cone when the second slider separated from the receiving part approaches the receiving part. It is characterized by being configured.

  The invention according to claim 7 is the invention according to claim 5, wherein the urging means is a coil spring spirally wound around a protruding pin between the first slider and the second slider. It is characterized by.

  The invention according to claim 8 is the invention according to any one of claims 1 to 7, wherein the receiving portion is constituted by six protrusions each having two clamping surfaces intersecting at 120 degrees, and the six protrusions are It is characterized in that the two pinching surfaces are equiangularly arranged on the same circumference with the apex angle of the two pinching surfaces as the center so that a six dead star is formed by the two pinching surfaces.

  According to the ninth aspect of the present invention, an inner cylinder having a slit extending in the axial direction is inserted into a cylindrical cap having an open spiral groove whose one end is open so as not to move in the axial direction and to be rotatable, and the open spiral groove is formed through the slit. A rod-shaped object receiving container having a protruding part to be engaged is inserted into the inner cylinder, and an end of the rod-shaped object inserted into the inner cylinder is improved to a rod-shaped object feeding container attached to the receiving part formed on the rod-shaped object receiving base. is there.

  Its characteristic configuration is that a pair of slits are formed so as to face the inner cylinder, and the other end side can be expanded from the other end side of the inner cylinder to the pair of slits to widen the width of the slit. A pair of cuts are formed on the other end side of the inner cylinder.

  In the rod-shaped object feeding container according to the present invention, a first slider having a through-hole communicating with the rod-shaped object attached to the receiving portion, a second slider provided on the first slider so as to be movable in the axial direction, Since the protruding pin provided in the second slider is inserted into the hole, the protruding pin pushes the rod-like object away from the receiving portion when the second slider separated by a predetermined distance from the receiving portion approaches the receiving portion. Therefore, when the rod-shaped object is consumed and cannot be used, the second slider is moved closer to the receiving part, and the remaining part of the rod-shaped object is detached from the rod-shaped object receiving base without touching the rod-shaped object. be able to.

  Here, if the flange portion with which the first slider can come into contact is formed at one end of the inner cylinder, and the auxiliary protrusion engaging with the open spiral groove through the slit is formed in the first slider, the second slider and the first slider The gap can be maintained at a predetermined interval, and it is possible to prevent the protruding pin from pushing out the rod-shaped object in the normal use state. Then, when the engagement of the auxiliary protrusion with the open spiral groove is released at the idle portion when the first slider comes into contact with the flange portion, when the rod-like object is consumed and cannot be used, The second slider can be brought close to the receiving portion by a relatively simple operation by simply rotating the cylindrical cap or the inner cylinder, whereby the rod-like object can be pushed out by the protruding pin.

  Furthermore, the rod-shaped object feeding container of the present invention has a pair of slits formed so as to face the inner cylinder, although the protrusions need to be inserted into the slit when the rod-shaped object receiving base is inserted into the inner cylinder. Since a pair of cuts communicating with the pair of slits from the other end of the cylinder is formed, when the width of the pair of cuts is widened, the width of the slit of the portion where the pair of cuts communicates is widened, and the other end of the inner cylinder The side is expanded. For this reason, it becomes possible to insert the rod-shaped object cradle into the inner cylinder with the other end of the inner cylinder open, and the protrusion can be inserted into the slit relatively easily. And if the notch is closed in a state where the protrusion is inserted into the slit, the rod-shaped object receiving base will not be detached from the inner cylinder, and the subsequent assembling work can be facilitated. After that, if the inner cylinder is inserted into the cylindrical cap so as not to move in the axial direction and is rotatable, the other end of the inner cylinder is prevented from being opened by the cylindrical cap, and the rod-shaped object receiving base inserted into the inner cylinder Can be avoided from separating from the inner cylinder.

Next, the best mode for carrying out the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 5, the rod-like object feeding container 10 of the present invention is fitted into the cylindrical cap 11 having a circular cross-section having an open spiral groove 11 a having one end open, and a circular cap 11. It has an inner cylinder 12. Each of the cylindrical cap 11 and the inner cylinder 12 is a resin molded product, and the open spiral groove 11 a is formed integrally with the cylindrical cap 11 when the cylindrical cap 11 is molded. A flange portion 13 having a larger diameter than the inner cylinder 12 is formed at one end of the inner cylinder 12, and a pair of slits 12 a extending in the axial direction are formed facing the inner cylinder 12. Further, on the other end side of the inner cylinder 12, there are cuts 12 b that communicate with the pair of slits 12 a from the end portions thereof and allow the opening on the other end side of the inner cylinder 12 as shown by broken line arrows in FIG. 5. It is formed.

  A rod-shaped object receiving base 16 to which an end of a rod-shaped object 14 inserted into the inner cylinder 12 from one end side is attached is inserted into the inner cylinder 12 so as to be movable in the axial direction. As shown in detail in FIG. 6, in the rod-shaped object receiving base 16 of the present invention, a receiving portion 17 a to which the end of the rod-shaped object 14 is attached is formed on one end side, and a through hole 17 b communicating with the rod-shaped object 14 is formed in the axial direction. The first slider 17 is formed to extend, and the second slider 18 is provided on the other end side of the first slider 17 so as to be movable in the axial direction. The first slider 17 is a cylindrical resin molded product that can be inserted into the inner cylinder 12, and the through hole 17 b is formed along the axis. The receiving portion 17a is composed of a pair of clamping pieces formed by raising both walls on one end side of the first slider 17, and the pair of clamping pieces 17a are formed integrally with the first slider 17, The end of the rod-like object 14 inserted into the cylinder 12 is configured to be clamped between the pair of clamping pieces 17a (FIG. 1). And the rod-shaped object 14 in this embodiment shall show a rod-shaped eraser.

  The second slider 18 is provided with a protruding pin 19 inserted through the through hole 17b. As shown in FIGS. 1 and 2, in the state where the second slider 18 is separated from the receiving portion 17 a by a predetermined distance, the tip of the protruding pin 19 is flush with one end of the first slider 17, and the end of the rod-like object 14. It is comprised so that a front-end | tip may contact | abut. For this reason, as shown in FIG. 3, when the second slider 18 spaced from the receiving portion 17a by a predetermined distance moves in the axial direction so as to approach the receiving portion 17a, the protruding pin 19 inserted through the through hole 17b. Also, it moves together with the second slider 18, and the protruding pin 19 is configured to push the rod-like object 14 away from the receiving portion 17a.

  The rod-shaped object receiving base 16 is provided with an urging means 21 for urging the second slider 18 to be separated from the receiving portion 17a, and the second slider 18 is prevented from being separated from the receiving portion 17a by a predetermined distance or more. The separation preventing means 22 is provided. The biasing means 21 in this embodiment stands on the second slider 18 so that the cone 21a tapered toward the second slider 18 formed on the first slider 17 and the tip of the cone 21a are clamped. 1 and 2, the pair of opposing pieces 21b are parallel to each other when the second slider 18 is spaced apart from the receiving portion 17a by a predetermined distance. As shown in FIG. 3, when the second slider 18 spaced apart from the receiving portion 17a by a predetermined distance approaches the receiving portion 17a, the tip is expanded by the cone 21a. Then, as shown in FIG. 3, the pair of opposed pieces 21b whose front ends are widened tends to close the front end widened by the elasticity, and the force to close the cones starts from the front ends of the pair of opposed pieces 21b. The force is pushed into the body 21a, whereby the biasing means 21 is configured to separate the second slider 18 from the receiving portion 17a.

  On the other hand, as shown in FIGS. 6 to 8, the separation preventing means 22 includes a hook 22a formed on the second slider 18 and a second slider 18 spaced apart from the receiving portion 17a by a predetermined distance. It consists of a to-be-latched opening 22b formed on the side wall of the first slider 17 to which the leading end locking portion 22c is locked. The locked opening 22b is formed long in the axial direction so as to allow the front-and-rear direction movement of the front-end locking portion 22c from the state where the front-end locking portion 22c is locked. Therefore, as shown in FIG. 7, the hook 22a has its tip locking portion 22c locked from the state where its tip locking portion 22c is locked to the locked opening 22b, as shown in FIG. It is allowed to move forward in the opening 22b. Since the hook 22a moves together with the second slider 18, the second slider 18 spaced apart from the receiving portion 17a by a predetermined distance is thereby configured to be able to approach the receiving portion 17a.

  As shown in FIG. 5, the rod-shaped object receiving base 16 is formed with a protrusion 23 that engages with the open spiral groove 11 a through the slit 12 a in the inner cylinder 12. As shown in FIG. 6, the protrusion 23 in this embodiment is formed on the second slider 18, and the auxiliary protrusion 24 formed on the first slider 17 extends in the axial direction so as to penetrate the slit 12a. A notch 17c that has a formed through portion 24a and an auxiliary engagement portion 24b that is formed in the through portion 24a and that actually engages with the open spiral groove 11a and opens adjacent to the auxiliary engagement portion 24b. Is formed.

  The protrusion 23 has an insertion portion 23a that is inserted through the notch 17c and passes through the slit 12a in the inner cylinder 12, and an engagement portion 23b that actually engages with the open spiral groove 11a. The insertion part 23a is configured to be movable in the axial direction inside the slit 12a together with the penetration part 24a while being inserted into the notch 17c. Therefore, as shown in FIGS. 1 and 2, the protrusion 23 is positioned on the other end side of the notch 17c in a state where the second slider 18 is spaced from the receiving portion 17a by a predetermined distance, and the auxiliary protrusion 24 The pitch, which is the axial distance between the engaging portion 24b and the engaging portion 23b in the protrusion 23, is set to an integral multiple of the axial pitch of the open spiral groove 11a (twice in FIG. 1), and the auxiliary engaging portion 24b Both engaging portions 23b are configured to engage with the open spiral groove 11a. Then, as shown in FIG. 3, in a state where the second slider 18 is close to the receiving portion 17a, that is, in a state where the protruding pin 19 has pushed out the rod-like object 14, the protruding portion 23 moves to one end side of the notch 17c, The engaging portion 23b and the auxiliary engaging portion 24b are configured to approach each other.

  The inner cylinder 12 is inserted into the cylindrical cap 11 so as not to move in the axial direction and to be rotatable. In this embodiment, an annular ridge 11b is formed on the inner peripheral surface of one end of the cylindrical cap 11, and the annular ridge 11b is fitted to the outer peripheral surface of one end of the inner tube 12 that is in sliding contact with the inner peripheral surface of the cylindrical cap 11. An annular recess 12c is formed. Then, as shown in FIG. 1, the annular ridge 11 b of the cylindrical cap 11 is fitted to the annular ridge 12 c of the inner cylinder 12. Thereby, the annular ridge 11b is prohibited from detaching from the annular groove 12c, and the inner cylinder 12 cannot move in the axial direction with respect to the cylindrical cap 11, but the rotation of the inner cylinder 12 with respect to the cylindrical cap 11 is allowed. And can be rotated freely.

  As shown in FIGS. 2 and 3, the flange portion 13 formed at one end of the inner cylinder 12 is configured so that the first slider 17 abuts and the rod-like object 14 cannot protrude any more. The flange portion 13 is a ring-shaped member and is formed integrally with the inner cylinder 12, and a grip projection 13 a (for facilitating gripping of the cylindrical cap 11 during a rotating operation) is formed on a part of the outer periphery thereof. FIG. 5) is formed. This gripping protrusion 13a also prevents rolling of the entire rod-shaped object feeding container when not in use. The flange portion 13 is formed with a cap receiving portion 13b and a surrounding portion 13c having a circular cross section. And the flange part 13 is comprised so that the front-end | tip of the receiving part 17a in the 1st slider 17 which comprises the rod-shaped object stand 16 may contact | abut inside the enclosure part 13c.

  When the receiving portion 17a of the first slider 17 comes into contact with the flange portion 13, an idle portion 11c for releasing the engagement of the auxiliary protrusion 24 with the auxiliary engaging portion 24b is formed on the inner surface on one end side of the cylindrical cap 11. The The idle portion 11 c is formed on the inner peripheral surface that is continuous with the annular ridge 11 b at the opening end of the cylindrical cap 11. As shown in FIG. 3, the axial width of the idle part 11c is such that both the engaging part 23b and the auxiliary engaging part 24b, which are close to each other by the push pin 19 pushing out the rod-like object 14, become the idle part 11c. Configured to be located. Here, reference numeral 26 shown in FIG. 1 is a protective cap 26 that is screwed into the cap receiving portion 13 b of the flange portion 13 and protects the end portion of the rod-like object 14.

Next, an assembling procedure of the rod-like object feeding container 10 will be described.
First, a rod-shaped object receiving base 16 as shown in FIG. 5 is assembled. In this assembly, as shown in FIG. 6, the projecting pin 19 is inserted into the through hole 17b of the first slider 17, and the insertion portion 23a of the projection 23 is inserted into the notch 17c while the second slider is inserted. 18 is overlapped on the other end side of the first slider, and as shown by a one-dot chain line arrow in FIG. 6, a tip locking portion 22c of the hook 22a formed on the second slider 18 is formed on the side wall of the first slider 17. The locked opening 22b is locked. Then, the separation preventing means 22 prevents the second slider 18 from being separated from the receiving portion 17a by a predetermined distance or more, and the rod-shaped object receiving base 16 in which both are integrated is obtained.

  Next, as shown in FIG. 5, the rod-shaped object receiving base 16 is inserted into the inner cylinder 12. At this time, it is necessary to insert both the protrusion 23 and the auxiliary protrusion 24 into the slit 12a. Here, in the rod-shaped object feeding container 10 of the present invention, a pair of slits 12a and 12a are formed so as to face the inner cylinder 12, and a pair of cuts 12b communicated with the pair of slits 12a from the other end side of the inner cylinder 12; 12b was formed. For this reason, when the width of the pair of cuts 12b is increased, the width of the slit 12a at the portion where the pair of cuts 12b communicates is widened, and the other end side of the inner cylinder 12 is expanded. For this reason, it becomes possible to insert the rod-shaped object receiving base 16 into the inner cylinder 12 with the other end side of the inner cylinder 12 opened as shown by the broken line arrow in FIG. be able to.

  Thereafter, by assembling the inner cylinder 12 to the cylindrical cap 11, opening of the other end of the inner cylinder 12 is prevented by the cylindrical cap 11. As shown in detail in FIG. 4, the inner cylinder 12 is inserted from the open end on one end side of the cylindrical cap 11, and the cylindrical cap 11 is rotated as shown by the arrow in the figure to project the protrusion 23 and the auxiliary into the open spiral groove 11a. The inner cylinder 12 is inserted into the cylindrical cap 11 while engaging both the protrusions 24. Here, when both the protrusion 23 and the auxiliary protrusion 24 are engaged with the open spiral groove 11a, the urging force by the urging means 21 is prevented by the separation preventing means 22, thereby receiving the second slider 18 and the auxiliary slider 24. The part 17a can be maintained at a predetermined interval. For this reason, both the protrusion 23 and the auxiliary | assistant protrusion 24 can be reliably engaged with the open spiral groove 11a by the comparatively simple operation | work which only rotates the cylindrical cap 11. FIG. Then, as shown in FIGS. 1 to 3, the annular ridge 11 b of the cylindrical cap 11 is fitted into the annular ridge 12 c of the inner cylinder 12. Thereby, the annular ridge 11b is prohibited from detaching from the annular groove 12c, and the inner cylinder 12 cannot move in the axial direction with respect to the cylindrical cap 11, but the rotation of the inner cylinder 12 with respect to the cylindrical cap 11 is allowed. Become so.

  The rod-like object 14 is inserted into the inner cylinder 12 from the surrounding portion 13 c of the flange portion 13, and its end is sandwiched between the receiving portions 17 a and attached to the rod-like object receiving stand 16. Then, the inner cylinder 12 is rotated with respect to the cylindrical cap 11 or the cylindrical cap 11 is rotated with respect to the inner cylinder 12, and the rod-shaped object receiving base 16 is moved to the other end side of the inner cylinder 12. Is immersed in the inner cylinder 12.

  In the rod-shaped object feeding container 10 configured as described above, the protective cap 26 is removed from the cap receiving portion 13b, and the inner cylinder 12 is rotated with respect to the cylindrical cap 11 or the cylindrical cap 11 is rotated with respect to the inner cylinder 12. Since the protrusion 23 and the auxiliary protrusion 24 of the rod-shaped object receiving base 16 are engaged with the slit 12a of the inner cylinder 12 and the open spiral groove 11a of the cylindrical cap 11, respectively, the rod-shaped object receiving base 16 is opened spirally. The rod-shaped eraser, which is a rod-shaped object 14 that is guided by the slit 12a while moving along the groove 11a and moves in the axial direction and is sandwiched and attached to the receiving portion 17a of the rod-shaped object receiving base 16 as shown in FIG. Accordingly, the cylindrical cap 11 appears and disappears from one end.

  On the other hand, as shown in FIG. 2, the rod-shaped eraser that is the rod-shaped object 14 is consumed by use, and the rod-shaped object receiving table 16 comes into contact with the flange portion 13 so that the rod-shaped object 14 cannot protrude any more. Here, the receiving portion 17 a formed on the first slider 17 of the rod-shaped object receiving base 16 first comes into contact with the flange portion 13. In this state, further axial movement of the first slider 17 is prohibited, but the auxiliary engagement portion 24b of the auxiliary protrusion 24 formed on the first slider 17 is located at the idle portion 11c, so that the cylindrical cap The rotation of the inner cylinder 12 with respect to 11 or the rotation of the cylindrical cap 11 with respect to the inner cylinder 12 is allowed.

  When the rotation of the inner cylinder 12 relative to the cylindrical cap 11 or the rotation of the cylindrical cap 11 relative to the inner cylinder 12 is continued from the state shown in FIG. 2 where the first slider 17 is in contact with the flange portion 13, the second slider 18 is formed. Since the protrusion 23 is still engaged with the open spiral groove 11a, the second slider 18 is guided along the open spiral groove 11a together with the protrusion 23 by the slit 12a and moves in the axial direction. It will approach. Then, the projecting pin 19 formed on the second slider 18 also moves together with the second slider 18 and pushes out the rod-like object 14 from the receiving portion 17a as shown in FIG. As a result, when the rod-like object 14 is consumed due to use and can no longer be used, the remaining portion of the rod-like object 14 can be removed from the rod-like object receiving base 16 without touching the rod-like object 14.

  In addition, the first slider 17 is in contact with the flange portion 13 and the second slider 18 is close to the receiving portion 17a so that the protrusion pin 19 pushes out the rod-like object 14, so that the protrusion 23 is engaged by the presence of the idle portion 11c. Since the engagement of the portion 23b with the open spiral groove 11a is also eliminated, the load generated when the rotation of the cylindrical cap 11 or the inner cylinder 12 is allowed and the rotation is restricted can be eliminated. When the cylindrical cap 11 or the inner cylinder 12 is rotated in the reverse direction from the state in which the protruding pin 19 has pushed out the rod-shaped object 14, that is, when the rod-shaped object 14 is rotated in the direction of immersion, the biasing means 21 Since the two sliders 18 are about to be separated from the receiving portion 17a, the protrusion 23 formed on the second slider 18 quickly moves from the idle portion 11c to the open spiral groove 11a. For this reason, the situation where the protrusion 23 and the auxiliary | assistant protrusion 24 remain in the idle part 11c can be avoided effectively.

  Further, since the rod-shaped eraser which is the rod-shaped object 14 is surrounded by the inner cylinder 12 over the entire length, it does not rattle during use, and there is no risk of breakage. Of course, it can be used by connecting to a writing instrument (not shown).

  In the above-described embodiment, the biasing means 21 including the cone 21a and the pair of opposed pieces 21b has been described. However, as illustrated in FIGS. 9 and 10, the biasing means 21 includes the first slider 17 and the biasing means 21. The coil spring 31 may be a spiral spring wound around the protrusion pin 19 between the second sliders 18.
