Description

Technical Field

[0001] The present invention relates to a dispensing container. Background Art

[0002] In a dispensing container that uses a core member by dispensing it, there is a problem that the core member detaches from a jig member when the core member is dispensed. In particular, in a case where the exposed area of the core member is large, in a case where the core member is pulled forward during use, or in a case where the core member has a shape such as a thin plate shape that is difficult to hold by the jig member, the core member is likely to detach from the jig member. In order to make it difficult for the core member to detach from the jig member, there is a prior art in which the core member is held by sandwiching two opposing surfaces on the short axis side of the core member with claw pieces (see Patent Document 1).

[0017] Next, the releasable container 100 according to the embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 It is a perspective view of the releasable container 100. Figure 2Fig. 1 is a perspective view of the dispensing container 100 with the lid member 6 removed. Figure 3 Fig. 2 is an exploded perspective view of the dispensing container 100.

[0018] The dispensing container 100 is, for example, a container for dispensing cosmetic products such as eyebrows and eyeliners, and core members S such as pencil leads. Hereinafter, the direction extending along the center of the dispensing container 100 in which the dispensing container 100 is dispensed is defined as the axial direction A (dispensing direction), the side where the core member S is dispensed in the axial direction A is defined as the front, and the opposite side is defined as the rear for explanation.

[0019] (Core member S) The core member S has an elongated shape with a length direction and a width direction in a cross-section orthogonal to the axial direction A. In the embodiment, the core member S is an elongated thin plate-like member having a substantially rectangular cross-section orthogonal to the axial direction A, and has a major axis and a minor axis. As will be described later, the cross-section of the core member S may be an elongated shape such as an ellipse, a long hexagon, a spindle shape, a gable roof shape, a single-slope roof shape, a trapezoid, a parallelogram, or a gourd shape, but is not limited thereto. Also, it may not be an elongated shape, but a square, a regular octagon, a circle, etc. The core member S is preferably an elongated shape, and the length in the length direction is preferably 2 times or more the length in the width direction. More preferably, it is 3 times or more.

[0020] Hereinafter, on the cross-section orthogonal to the axial direction A in the dispensing container 100 in a state where the core member S is held, the major axis direction (length direction) of the core member S is defined as the vertical direction, and the minor axis direction (width direction) is defined as the left-right direction for explanation. In addition, one of the surfaces of the core member S parallel to the major axis is defined as the right side surface, the other is defined as the left side surface, and one of the surfaces parallel to the minor axis extending in the left-right direction (the side held by the clamp portion 5A described later) is defined as the upper surface, and the other is defined as the lower surface for explanation, where the major axis extends in the vertical direction and is centered on the axis A.

[0021] (Dispensing container 100) The dispensing container 100 includes an outer cylinder 1, an inner cylinder 2 disposed inside the outer cylinder 1, a threaded member 3 disposed inside the inner cylinder 2, a core housing member 4 inserted into the front side of the inner cylinder 2, a clamp member 5 for holding the core member S, and a lid member 6.

[0022] (Outer cylinder 1) Figure 4It is a sectional perspective view of the outer cylinder 1. The outer cylinder 1 is a bottomed cylindrical member with a substantially constant outer diameter, an opening at the front side and a closed rear side. The inner surface of the outer cylinder 1 has a diameter at the front side of the substantially central portion in the direction of the axis A larger than that at the rear side, and an outer cylinder inner surface stepped portion 11 is formed at the portion where the diameter changes. From the outer cylinder inner surface stepped portion 11 toward the front side, a plurality of outer cylinder inner surface rib portions 12 extending in the direction of the axis A in parallel with each other at substantially the same length are formed at equal intervals in the circumferential direction. At the front side of the inner surface of the outer cylinder 1, an outer cylinder inner surface circumferential groove portion 13 extending in the circumferential direction is formed.

[0023] (Inner cylinder 2) Figure 5 It is a sectional perspective view of the inner cylinder 2. The inner cylinder 2 is a cylindrical member with an outer diameter smaller than the inner diameter of the outer cylinder 1, and is a bottomed cylindrical member with an opening at the front side and a closed rear side.

[0024] On the outer surface of the inner cylinder 2, a plurality of inner cylinder outer surface rib portions 21 extending in the direction of the axis A in parallel with each other at substantially equal length are formed at substantially equal intervals in the circumferential direction from the rear end portion toward the front side. In addition, an inner cylinder positioning rib 22 is formed at a position slightly behind the front end on the outer surface of the inner cylinder 2. At a position behind the inner cylinder positioning rib 22, an inner cylinder outer surface rear circumferential convex portion 23 extending in the circumferential direction is provided, and at a position in front of the inner cylinder positioning rib 22, circular convex inner cylinder outer surface convex portions 24 are formed at four positions in the circumferential direction.

[0025] At the rear end of the inner surface of the inner cylinder 2, inner cylinder inner surface longitudinal rib portions 25 are formed at four positions. At the front side of the inner surface of the inner cylinder 2, an inner cylinder inner surface circumferential groove portion 26 is formed.

[0026] Figure 6 It is a view showing the state of the releasable container 100 with the lid member 6 removed, in which the jig member 5 (i.e., the core member S) is not released. Figure 6 Part (a) in it is a side view. Figure 6 Part (b) in it is a sectional view along the vertical direction.

[0027] When the inner cylinder 2 is disposed inside the outer cylinder 1, the inner cylinder outer surface rib portions 21 are fitted between the adjacent outer cylinder inner surface rib portions 12. And, as shown in part (b) of Figure 6 , the rear surface of the inner cylinder positioning rib 22 of the inner cylinder 2 abuts against the front surface of the outer cylinder 1, and the inner cylinder outer surface rear circumferential convex portion 23 of the inner cylinder 2 is engaged with the outer cylinder inner surface circumferential groove portion 13 of the outer cylinder 1. Accordingly, the movement of the inner cylinder 2 in the direction of the axis A inside the outer cylinder 1 is restricted, and relative rotation with the outer cylinder 1 is prevented.

[0028] (Thread member 3) Figure 7It is a sectional perspective view of the threaded member 3. The threaded member 3 is formed with a plurality of threaded outer surface rib portions 31 extending in the direction of the axis A at substantially equal intervals in the circumferential direction on the outer periphery. An internal thread portion 32 is formed on the inner periphery of the threaded member 3.

[0029] When the threaded member 3 is disposed inside the inner cylinder 2, the threaded outer surface rib portions 31 engage with the longitudinal rib portions 25 on the inner surface of the inner cylinder. Accordingly, relative rotation between the threaded member 3 and the inner cylinder 2 is prevented. In addition, the threaded member 3 is restricted from moving in the direction of the axis A by being sandwiched between the rear end of a core housing member 4 described later and the bottom surface of the inner cylinder 2.

[0030] (Core housing member 4) Figure 8 It is a sectional perspective view of the core housing member 4. The core housing member 4 is tubular and has a front housing portion 4A and a rear connecting portion 4B. As Figure 2 、 Figure 3 and so on show, the cross-section of the outer surface of the front housing portion 4A of the core housing member 4 in the direction orthogonal to the axis A is substantially rectangular at the front side, but circular at the rear side.

[0031] Figure 9 It is Figure 2 a cross-sectional view in the direction of the I-I line of Figure 9 and the (a) part in Figure 9 is the embodiment, and the (b), (c), (d), and (e) parts in Figure 9 are the modified modes described later. In the embodiment, as shown in the (a) part in

[0032] (Opening portion 40) Return Figure 8 and so on, at the front end of the front housing portion 4A of the core housing member 4, an opening portion 40 for releasing the core member S is formed. The lower surface portion 44 extends to a position closer to the front side than the upper surface portion 43. That is, the opening portion 40 of the front housing portion 4A is formed in a shape with an inclined notch when viewed from the side, and the lower side edge of the front end of the front housing portion 4A is located at a position closer to the front side than the upper side edge. In addition, in the embodiment, the contour when the opening portion 40 is viewed from the side is curved so as to bulge downward, but it may also be a straight line. In addition, during use, the opening portion 40 can be enlarged by being curved so as to bulge downward. Therefore, the upper side of the core member S is used, and even if the lower side of the core member S decreases, the core housing member 4 is not likely to cause interference during use.

[0033] (Core housing member 4) The lower surface portion 44 of the core housing member 4 is a core holding portion that covers the surface of the outer peripheral surface of the core member S that is not covered by the clamp member 5 from below.

[0034] In addition, the jig part 5A does not hold the core component S covering the whole in the vertical direction, but the lower side of the core component S is exposed from the jig part 5A, which will be described later. On the other hand, as shown in the (a) part of Figure 9 , the right side face 41 and the left side face 42 of the core housing component 4 are shaped to protrude toward the core component S by an amount corresponding to the thickness of the core component S. And the left and right surfaces of the part of the lower side of the core component S exposed from the jig part 5A are directly covered by the protruding parts 41a and 42a.

[0035] In addition, the right side face 41 of the core housing component 4 covers the jig part 5A that holds the core component S and the part of the core component S exposed from the jig part 5A from the right side (the first direction). The left side face 42 of the core housing component 4 covers the jig part 5A that holds the core component S and the part of the core component S exposed from the jig part 5A from the left side (the second direction). In addition, the upper surface part 43 of the core housing component 4 covers the jig part 5A that holds the core component S from above (the third direction).

[0036] Between the part of the protruding parts 41a and 42a of the right side face 41 and the left side face 42 that directly cover the core component S and the core component S, there is a slight gap to enable the core component S to slide in the direction of the axis A. However, this gap is small, and the core component S can be prevented from swaying left and right by the right side face 41 and the left side face 42.

[0037] Moreover, the lower surface part 44 extends forward more than the upper surface part 43, and the exposed lower surface of the core component S can be held longer in the direction of the axis A by the lower surface part 44, so the stability of the core component S is improved.

[0038] (Guide part 45) As described above, the right side face 41 and the left side face 42 of the core housing component 4 are shaped such that the lower part protrudes toward the core component S by an amount corresponding to the thickness of the jig part 5A. And the upper surfaces of the protruding parts 41a and 42a respectively form guide parts 45 which are stepped surfaces parallel to the left and right directions.

[0039] (Rear connecting part 4B) An O-ring holding circumferential groove part 46 is provided on the rear side of the outer surface of the rear connecting part 4B, and a housing component outer surface circumferential convex part 47 is formed on the front side.

[0040] In a state where an O-ring 7 is installed in the O-ring holding circumferential groove part 46 of the rear connecting part 4B, when the rear connecting part 4B is inserted into the inner cylinder 2 from the front side, the housing component outer surface circumferential convex part 47 engages with the inner cylinder inner surface circumferential groove part 26. Accordingly, the core housing component 4 is connected in a state where it can rotate relative to the inner cylinder 2 and the movement in the direction of the axis A is restricted.

[0041] (Step portion) As Figure 6 shown in part (b) of Figure 8 and as shown in Figure 8 , on the inner surface side of the connecting portion between the front storage portion 4A and the rear connecting portion 4B in a vertically penetrating cross-section, a forward step portion 49A facing the front side is formed. As Figure 8 shown in Figure 8 , on the inner surface side of the connecting portion between the front storage portion 4A and the rear connecting portion 4B in a horizontally penetrating cross-section, a rearward step portion 49B facing the rear side is formed.

[0042] (Jig member 5) Figure 10 is a perspective view of the jig member 5, Figure 11 and is a cross-sectional view of the jig member 5. The jig member 5 is disposed inside the core storage member 4 and is movable relative to the core storage member 4 in the direction of axis A. The jig member 5 has a jig portion 5A and a jig driving portion 5B that drives the jig portion 5A in the direction of axis A, and the jig portion 5A and the jig driving portion 5B are detachable.

[0043] (Jig portion 5A) The jig portion 5A has a front jig portion 5a, a central jig portion 5b, and a rear jig portion 5c.

[0044] (Front jig portion 5a) As Figure 10 shown in Figure 10 , the cross-section of the front jig portion 5a orthogonal to the direction of axis A is in the shape of the Japanese katakana character "コ", and covers the outer peripheral surface on the rear side in the release direction of the core member S through the right plate portion 51, the left plate portion 52, and the upper plate portion 53, and holds the core member S. Among them, the right plate portion 51 covers the outer peripheral surface on the rear side in the release direction of the core member S from the direction orthogonal to the direction of axis A of the core member S, that is, from the right side (the first direction), the left plate portion 52 covers the outer peripheral surface on the rear side in the release direction of the core member S from the left side (the second direction), and the upper plate portion 53 covers the outer peripheral surface on the rear side in the release direction of the core member S from above (the third direction). In addition, the first direction and the second direction are the directions along the width direction of the core member whose cross-section orthogonal to the release direction is an elongated shape, and the third direction is the direction along the length direction of the core member S.

[0045] When the front jig portion 5a holds the core member S, the vertical lengths of the right plate portion 51 and the left plate portion 52 are shorter than the vertical length of the core member S. Therefore, the lower side of the core member S is exposed from the front jig portion 5a. As described above, the exposed portion is covered by the core storage member 4.

[0046] Moreover, the cross-section of the portions 41a and 42a of the core housing member 4 that protrude toward the core member S and are orthogonal to the axis A direction matches the lower surface portion 44 and is in a "U" shape. Further, the protruding portions 41a and 42a are mated with the lower surface portion 44, extend forward compared to the upper surface portion 43, and cover the left and right surfaces of the portion of the lower side of the core member S that is exposed from the front portion 5a of the jig.

[0047] According to this structure, the lower surface portion 44 of the core housing member 4 and the protruding portions 41a and 42a not only directly hold the lower surface of the core member S that is exposed over a long distance in the axis A direction, but also directly hold the left and right surfaces thereof. Therefore, the stability of the core member S is further improved. In addition, in Figure 9 except for Figure 9 the (b) part in

[0048] (Anti-disengagement rib 54) On the inner sides of the right plate portion 51 and the left plate portion 52 that face the core member S, two anti-disengagement ribs 54 (convex portions) extending vertically in the direction orthogonal to the release direction are respectively formed.

[0049] (Holding method) The interval (in the left-right direction on the inner side of the opening) between the right plate portion 51 and the left plate portion 52 is greater than or equal to the thickness (left-right direction length) of the core member S. Due to this structure, the core member S can be inserted into the front portion 5a of the jig from the lower side, which is the opening side of the "U" shape, upward. In the embodiment, the right plate portion 51 and the left plate portion 52 are respectively plate-shaped and arranged in parallel.

[0050] Here, the interval in the left-right direction between the anti-disengagement rib 54 formed on the right plate portion 51 and the anti-disengagement rib 54 formed on the left plate portion 52 is less than or equal to the thickness (left-right direction length) of the core member S. Therefore, when the rear end of the core member S is inserted into the front portion 5a of the jig from the lower side, which is the opening side of the "U" shape, upward and is pressed into a position where the upper surface of the core member S abuts or is close to the upper plate portion 53, the anti-disengagement rib 54 bites into the core member S and clamps the core member S between the right plate portion 51 and the left plate portion 52.

[0051] Moreover, the direction of the anti-disengagement rib 54 of the front portion 5a of the jig is the same as the insertion direction of the core member S. Therefore, when inserting the core member S, the core member S is not easily broken and is also easy to assemble.

[0052] The jig member 5 (front portion 5a of the jig) covers the outer peripheral surface on the rear side in the release direction of the core member S from three directions: the first direction orthogonal to the release direction, the second direction facing the first direction, and the third direction orthogonal to the release direction and orthogonal to the first direction and the second direction.

[0053] Thus, the core component S is held by the clamping portion 5A from three directions (three surfaces), so that the core component S is not easily detached from the clamping member 5.

[0054] In particular, in the present embodiment, the cross-section of the clamping portion 5A orthogonal to the direction of the axis A is in a "U" shape and is a structure integrally connected without gaps. Therefore, the core component S can be held more firmly from three directions (three surfaces). It can be configured such that even when the released front clamping portion 5a becomes exposed from the opening 40 of the core housing member 4, the core component S is not easily detached from the clamping member 5.

[0055] Since the anti-detachment rib 54 is inserted into the clamping portion 5A in the up-and-down direction orthogonal to the direction of the axis A, the core component S is not easily detached in the direction of the axis A.

[0056] In particular, when, as in the present embodiment, the core housing member 4 has an opening 40 on the upper side and is used in such a way that the upper surface of the core component S is coated, the core may sometimes be pulled forward in the direction of the axis A. However, in the present embodiment, since the anti-detachment rib 54 is inserted into the clamping portion 5A in the up-and-down direction orthogonal to the direction of the axis A, even if the core is pulled forward in the direction of the axis A, the core component S is not easily detached in the direction of the axis A.

[0057] The core component S is clamped between the right plate portion 51 and the left plate portion 52 of the clamping portion 5A in the left-right direction, thus preventing movement or rotation in the left-right direction. The upper plate portion 53 is arranged above the core component S, and the lower surface portion 44 of the core housing member 4 is arranged below it, thus preventing movement or rotation in the up-and-down direction.

[0058] The lower surface portion 44 of the core housing member 4 is arranged on the lower surface of the exposed portion of the core component S that is not covered by the clamping portion 5A. Therefore, the lower surface of the core component S is protected, and it is not easy for the core component S to break, etc., even when it falls or the like. Also, the lower surface portion 44 prevents the core component S from falling off downward.

[0059] (Clamping central portion 5b) The outer shape of the clamping central portion 5b is such that the right plate portion 51, the left plate portion 52, and the upper plate portion 53 of the front clamping portion 5a are extended rearward, and a plate member is arranged in the gap therebetween. The cross-section of the plate member is substantially the same as that of the core component S, that is, it is longer than the gap in the up-and-down direction and has a rectangular cross-section. A stepped portion is formed between the portion extended from the right plate portion 51 and the left plate portion 52 in the clamping central portion 5b and the plate member extending further downward therefrom. This stepped portion becomes a sliding portion 55 that is continuous with the lower surfaces of the right plate portion 51 and the left plate portion 52 of the front clamping portion 5a and is parallel to the left-right direction.

[0060] In addition, when the core component S attempts to move rearward (to overcome the anti-disengagement force of the rib 54), the rear end of the core component S abuts against and is positioned on the front surface of the portion of the jig part 5A that corresponds to the plate component disposed in the above-mentioned gap, and does not move further rearward.

[0061] The sliding part 55 of the jig part 5A engages with the guiding part 45 of the core housing component 4. When the jig part 5A is released, the guiding part 45 guides the sliding part 55 to move straight, so that the jig component 5 can move stably in the direction of the axis A.

[0062] (Jig rear part 5c) A clamping part 56 is formed at the rear end of the jig rear part 5c. The clamping part 56 has an upper claw part and a lower claw part that extend in the direction of the axis A. Concave parts 56a are formed on the surface sides where the upper claw part and the lower claw part face each other, and the convex part 57a at the front end of the jig driving part 5B is clamped. In the present embodiment, the concave part 56a is in a shape that penetrates in the left-right direction and is a shape in which the upper claw part and the lower claw part are easily elastically deformed.

[0063] (Jig driving part 5B) The jig driving part 5B is an elongated rod-shaped component and has a front-side extending part 57 and a rear-side thread engaging part 58.

[0064] (Rear-side thread engaging part 58) The rear-side thread engaging part 58 is a cylindrical component with external thread protrusions 5Ba formed on the rear side. Two external thread protrusions 5Ba are formed respectively in two positions in the circumferential direction, and a total of four are formed.

[0065] (Front-side extending part 57) The front-side extending part 57 extends further forward than the front end of the rear-side thread engaging part 58, and a convex part 57a is formed at the front end of the front-side extending part 57. The convex part 57a fits into the concave part 56a provided between the facing surfaces of the upper claw part and the lower claw part of the clamping part 56 and is detachably clamped between the upper claw part and the lower claw part.

[0066] In addition, when the rear end of the concave part 56a is located at a position rearward of the forward step part 49A, the upper claw part and the lower claw part cannot be deformed, so disassembly and assembly cannot be performed. On the other hand, when the rear end of the concave part 56a is located at a position forward of the forward step part 49A, the upper side claw part and the lower side claw part can be deformed, and the jig part 5A can be pinched with fingers to perform disassembly and assembly in a state where the jig part 5A is exposed from the opening part 40.

[0067] A jig-side step part 59 facing forward is formed between the rear-side thread engaging part 58 and the front-side extending part 57.

[0068] (Cover component 6) A cover inner surface circumferential groove 61 is formed on the rear side of the inner surface of the cover member 6. The cover member 6 can be attached to and detached from a portion other than the cover member 6 of the release container 100 (hereinafter referred to as the release container body). When the cover member 6 is attached to and detached from the release container body, the cover inner surface circumferential groove 61 of the cover member 6 engages with the inner tube outer surface convex portion 24 formed on the inner tube 2 of the release container body, whereby the cover member 6 is attached to the release container body.

[0069] (Operation of the Dispensing Container 100) exist Figure 6 In the state shown where the clamp member 5 (core member S) is not released, the rear end of the clamp center portion 5b of the clamp portion 5A of the clamp member 5 abuts against the forward step portion 49A of the core storage member 4. This restricts the clamp member 5 (core member S) from further rearward movement.

[0070] The release container 100 of the embodiment is a rotation release container. When the outer tube 1 rotates relative to the core storage member 4 about the axis A, the inner tube 2 and the threaded member 3 also rotate relative to the core storage member 4 about the axis A.

[0071] Then, the internal thread portion 32 of the screw member 3 meshes with the external thread projection 5Ba provided on the outer periphery of the clamp driving portion 5B of the clamp member 5 , so that the clamp member 5 moves forward in the axis A direction.

[0072] Thus, the release container 100 of the embodiment is a rotation release type, and can be released without contacting the core member S, so it is easy to use. However, it is not limited to this, and the release container can also be released by a knocking method based on a knocking operation or by a sliding method pushed in the front-rear direction along the axis A direction.

[0073] Figure 12 FIG. 1 is a diagram showing a state where the release-type container 100 is in a state where the cover member 6 is removed and the clamp member 5 (ie, the core member S) is released to the maximum extent. Figure 12 Part (a) is the side view. Figure 12 Part (b) is a cross-sectional view along the up-down direction. Figure 12 (c) is a cross-sectional view along the left-right direction.

[0074] When the clamp component 5 is released, the clamp side step portion 59 abuts against the rear step portion 49B, thereby preventing the clamp component 5 from being further released, wherein the clamp side step portion 59 is formed between the rear side threaded engagement portion 58 and the front side extension portion 57 of the clamp driving portion 5B and faces the front side; the rear step portion 49B is formed at the connecting portion between the front side receiving portion 4A and the rear side connecting portion 4B in the core receiving portion 4 and faces the rear side.

[0075] When the jig member 5 (i.e., the core member S) is released to the maximum extent, the front end of the jig portion 5A can move near the front end of the lower surface portion 44 (core holding portion) (the front end positions of the jig portion 5A and the lower surface portion 44 (core holding portion) are within ±2.0 mm in the front-rear direction). More specifically, it can move near the front end and not exceed the front end position (the front end of the jig portion 5A can move to a position within 2.0 mm behind the front end position of the lower surface portion 44 (core holding portion)).

[0076] More preferably, it can move near the front end and not exceed the front end position. Since the front end of the jig portion 5A can move near the front end of the lower surface portion 44 (core holding portion) and move to a position closer to the front side than the upper surface portion 43 of the core housing member 4, except for the portion held by the jig portion 5A, the core member S can be substantially used up.

[0077] On the other hand, in the case where the dispensing container 100 is a container for dispensing cosmetics such as eyebrows and eyeliners as the core member S, when the front end of the jig portion 5A moves forward beyond the front end of the lower surface portion 44, the jig portion 5A may sometimes come into contact with the skin and cause discomfort. However, in the embodiment, the front end of the jig portion 5A does not move forward beyond the front end of the lower surface portion 44, so this situation does not occur.

[0078] When the core member S is used up, if the jig portion 5A is pulled forward, the recess 56a formed in the clamping portion 56 of the jig portion 5A disengages from the protrusion 57a formed at the front end of the jig driving portion 5B, so the jig portion 5A can be pulled out. And when the jig portion 5A holding the new core member S is inserted from the opening 40 of the core housing member 4 to the rear side in the direction of the axis A, the recess 56a formed in the clamping portion 56 of the jig portion 5A can be engaged with the protrusion 57a formed at the front end of the jig driving portion 5B, thereby enabling easy replacement of the core member S.

[0079] Moreover, since the thickness of the core member S is constant and it is relatively long in the up-down direction, even if it decreases due to use, it can usually be applied with the same width, making it easy to use.

[0080] (Alternative embodiment) The embodiments of the present invention have been described above, but the present invention is not limited thereto, and various modifications can be made.

[0081] In Figure 9 the embodiment shown in part (a) of [], the up-down lengths of the right plate portion 51 and the left plate portion 52 are shorter than the up-down length of the core member S, so the lower side of the core member S is exposed from the front portion 5a of the jig. However, it is not limited thereto, as shown in Figure 9As shown in part (b), it is also possible that the vertical lengths of the right plate portion 51 and the left plate portion 52 are substantially the same as the vertical length of the core member S, and the lower side of the side surface of the core member S does not protrude from the front portion 5a of the jig.

[0082] In addition, in the embodiment, the cross-section of the core member S orthogonal to the direction of the axis A is substantially rectangular. However, it is not limited thereto. As Figure 9 shown in (c), the cross-section of the core member S orthogonal to the direction of the axis A may also be elliptical. In addition, it is also possible that Figure 9 in (c), the gap between the front portion 5a of the jig and the core member S is eliminated, and the cross-section of the front portion 5a of the jig is substantially U-shaped or substantially V-shaped.

[0083] In the embodiment, the cross-section of the front portion 5a of the jig orthogonal to the direction of the axis A is "C"-shaped. However, it is not limited thereto. As Figure 9 shown in (e), the right plate portion 51 that covers the outer peripheral surface of the core member S from the right side (the first direction), the left plate portion 52 that covers the outer peripheral surface of the core member S from the left side (the second direction), and the upper plate portion 53 that covers the outer peripheral surface of the core member S from the upper side (the third direction) may also be discontinuous.

[0084] In addition, in the embodiment, the cross-section of the core member S orthogonal to the direction of the axis A is a substantially rectangular shape that is long in the vertical direction. However, it is not limited thereto. As Figure 9 shown in part (d), the cross-section of the core member S orthogonal to the direction of the axis A may also be square.

[0085] In the embodiment, by making the jig portion 5A and the jig driving portion 5B detachable, the core member S can be replaced. However, it may be different from the embodiment, making the jig portion 5A and the jig driving portion 5B integral, or the jig portion 5A and the jig driving portion 5B may be fitted in a non-detachable manner using other components.

[0086] In addition, in the embodiment, on the surfaces of the right plate portion 51 and the left plate portion 52 facing the core member S, two anti-disengagement ribs 54 (protrusions) extending vertically in the direction orthogonal to the release direction are respectively formed. However, it may be different from the embodiment, and one anti-disengagement rib may be formed respectively. In addition, the number of anti-disengagement ribs on the right plate portion and the left plate portion may also be different, or the anti-disengagement rib (protrusion) may be formed on the surface of either the right plate portion or the left plate portion. In addition, the width of the anti-disengagement rib 54 in the front-rear direction may also be widened.
