thread containment

Abstract

Pull it out without tangling the thread. [Solution] Two hooks 22 and 24 are provided on the flat plate 2 so as to be symmetrically positioned on both sides of a virtual straight line on the flat plate 2. The thread 36, which is wound in a crisscross manner to form two loops 32 and 34, tends to spread out in a relaxed state, with the loops 32 and 34 located on both sides of the virtual line and the two hooks 22 and 24 located within the two loops 32 and 34. The intersection of the thread 36 passes through the virtual straight line, and the portion of the loops 32 and 34 closer to the virtual straight line is shorter than the portion further away from the virtual straight line. The thread 36 is pulled out from between the hooks 22 and 24 on the opposite side of the intersection.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The thread wound around this thread storage body is quite long, and both of the two loops are wound multiple times. Therefore, the thickness of the intersection portion of the two loops becomes thick, and when pulling out the thread, the thread is likely to get entangled in the loop, and the thread cannot be pulled out smoothly.

[0005] An object of the present invention is to provide a thread storage body that can smoothly pull out the thread even when a long thread is wound.

Means for Solving the Problems

[0006] A thread container according to one aspect of the present invention has a flat plate. The flat plate can be of various shapes, such as rectangular, square, circular, or elliptical, and can be made of, for example, paper or synthetic resin. Two hooks are provided on the flat plate so as to be positioned symmetrically on both sides of a virtual straight line on the flat plate. The hooks can be anything that the thread can catch on, and can be cylindrical, elliptical, or hemispherical, for example. The thread is wound so as to cross to form two loops. This thread tends to unfold when not under tension. Both loops of the thread are multiple loops and are located on both sides of the virtual straight line, the two hooks are located within the two loops, and the intersection of the threads passes through the virtual straight line. Alternatively, the hooks can be located on one end of the virtual straight line and the intersection on the other side of the virtual straight line. In the two loops, the portion closer to the virtual straight line is shorter than the portion further away from the virtual straight line, and the thread is pulled out from between the hooks to the opposite side of the intersection.

[0007] In a thread container configured in this way, the two loops are positioned on either side of a virtual straight line, so the intersection of the two loops is stretched, making it thinner than when the thread is wound in a figure-eight shape. Therefore, the thread is less likely to get tangled in the loops when unraveling. Furthermore, since the portion of the two loops closer to the virtual straight line is shorter than the portion further away from the virtual straight line, when the thread is pulled out from between the hooks on the opposite side of the intersection, even if most of one loop and the thread from the intersection of the other loop to near the hook are unraveled, the thread from the hook of the other loop to the intersection remains untangled, and the previously unraveled loops do not get tangled with the loops that are closer to them, allowing for smooth unraveling. Similarly, each loop can be unraveled smoothly.

[0008] Furthermore, additional hooks can be provided on the flat plate such that each of the two aforementioned loops has a separate hooking portion having a thread-smoothing surface.

[0009] With this configuration, loops can be attached to different attachment points, The length of the loop from the intersection to the hook can be made shorter for each individual than the length from the hook to the intersection, allowing the thread loop to be unraveled more smoothly.

[0010] Furthermore, a contact portion can be provided on the flat plate near the intersection of the thread loops so as to contact this intersection. With this configuration, the thin state at the intersection of the two loop portions can be reliably maintained.

[0011] Furthermore, the two wing bodies can also be fixed to the flat plate in such a state that they extend from around the two hooking parts, passing over the two loops, and towards the intersection. With this configuration, even if the loops try to spread out, the wing bodies will hold them in place, preventing the thread from getting tangled in other loops when unraveling it. It is also desirable that the length of the wing body from the intersection of the loops to the hooking part is shorter than the length from the hooking part to the intersection.

[0012] The flat plate can also be bent so that the two loops overlap. This allows the thread container to be made smaller.

[0013] A thread retaining portion can also be provided extending from the virtual straight line or its vicinity onto the two loops. Alternatively, another thread retaining portion can be provided extending from the opposite side of the virtual straight line onto the two loops. This prevents the thread from getting tangled in other loops when unraveling it.

[0014] Another embodiment of the present invention provides a thread housing that, similarly to the embodiment described above, has a flat plate and hooks. It further has a figure-eight shaped thread wound in a cross pattern to form two loops. The thread tends to unfold in a relaxed state, and each loop of the thread is a multi-loop, and the figure-eight shaped thread is positioned on the flat plate such that the two loops are on either side of a virtual line, the two hooks are located within the two loops, and the intersection of the threads passes through the virtual line, and the flat plate is bent at a bend through which the virtual line passes so that the two loops overlap, the portion of the two loops on the virtual line side contacts the bend, and the thread is pulled out from between the hooks to the opposite side of the intersection.

[0015] In this configuration, when folded, the portion of the two figure-eight loops on the folded side comes into contact with the folded part, preventing it from spreading further. The portion of the two loops opposite the folded part can spread due to the properties of the yarn. As a result, the length of the portion of the loop on the folded side, corresponding to the hooking part from the intersection, becomes shorter than the length of the portion of the loop opposite the folded part, corresponding to the intersection from the hooking part. Consequently, the yarn can be pulled out smoothly, as described in the above embodiment.

[0016] Similar to the modifications in the above embodiment, additional hooking parts, contact parts, thread retaining parts, and other thread retaining parts may be provided. Alternatively, a thread restraining part may be provided between the two loops, at least near the intersection. [Effects of the Invention]

[0017] As described above, the thread holder according to the present invention allows for smooth drawing of threads without tangling. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0019] As shown in FIGS. 1 and 2, the yarn container of the first embodiment of the present invention has a flat plate 2. The flat plate 2 is, for example, a rectangular one made of paper, and has an upper side 4, a lower side 6, side sides 8 and 10, and has a virtual straight line indicated by a dashed line on its center line (for example, a line connecting the centers of the upper side 4 and the lower side 6). Boundary lines 12 and 14 are formed on both sides of this virtual line, and the region surrounded by the boundary lines 12 and 14 is the connecting portion 16, and the regions on both sides of the connecting portion 16 are the lower plate 18 and the upper plate 20. The lower plate 18 and the upper plate 20 are rectangles of the same shape.

[0020] Hooking portions 22 and 24 are formed near the upper edges 4 of the lower plate 18 and the upper plate 20, respectively. These hooking portions 22 and 24 are located, for example, on the central axes of the lower plate 18 and the upper plate 20, and are arranged symmetrically with respect to a virtual straight line as the axis of symmetry. The hooking portions 22 and 24 are formed in the same shape, for example, hemispherical, and their entire outer surface is a thread sliding surface. The hooking portions 22 and 24 can be made of, for example, paper.

[0021] Further hooking parts 26 and 28 are formed on the lower plate 18 and upper plate 20, which are closer to the imaginary straight line and closer to the lower edge 6 than the hooking parts 22 and 24. The further hooking parts 26 and 28 are hemispherical in shape, arranged symmetrically with respect to the imaginary straight line as the axis of symmetry, and their entire outer surface is a thread sliding surface. The further hooking parts 26 and 28 are identical in shape, and their diameters are somewhat smaller than those of the hooking parts 22 and 24. It is also possible to make the diameters of the further hooking parts the same as those of the hooking parts 22 and 24. The further hooking parts 26 and 28 can also be made of, for example, paper.

[0022] The contact portion 30 is formed so as to be located on a virtual straight line, closer to the bottom edge 6 than the other hook portions 26 and 28. As shown in Figure 1, the contact portion 30 has a shape that is, for example, oval, with the bottom edge 6 side and the opposite side being curved, rising up from the middle, and as shown in Figure 2, the side opposite to the flat plate 2 is convexly curved, and the curved shape of the contact surface with the flat plate 2 and the convex curved shape each function as a thread sliding surface. The shape of the contact portion 30 as viewed from the sides 8 and 10 can also be hemispherical or semi-elliptical. The contact portion 30 can also be made of, for example, paper.

[0023] As shown in Figure 1, a thread, such as a fishing line 36, is positioned between the contact portion 30, the hook portion 22, 24, and the other hook portions 26, 28 such that one loop 32 is formed between the contact portion 30, the hook portion 22, and another hook portion 26, and another loop 34 is formed between the contact portion 30, the hook portion 24, and another hook portion 28. In loop 32, the hook portion 22 and the other hook portion 26 are located within the loop 32, and in loop 34, the hook portion 24 and the other hook portion 28 are located within the loop 34. These loops 32 and 34 are positioned symmetrically with respect to a virtual straight line as the axis of symmetry.

[0024] The fishing line 36 is pre-wound by a winder, for example, as shown in Figure 3. One end of the fishing line to be wound is fixed between the contact portion 30a and the lower edge 6a of the winder, as indicated by the symbol X in Figure 3. The fishing line 36 is then passed through the curved corners on the lower edge 6a and side edge 10a of the contact portion 30a, directed toward the hook portion 24a on the central side of the winder as indicated by arrow a, hooked onto the upper edge 4a portion of the hook portion 24a, then directed toward another hook portion 28a on the side edge 10a as indicated by arrow b, made contact with the side edge 10a portion of that hook portion, and then directed toward the contact portion 30a as indicated by arrow c, making contact with the entire curved portion on the lower edge 6a side of the contact portion 30a. This forms a loop 34. The thread 36 is passed through the curved portion on the lower side 6a of the contact portion 30a, and from the corner on the side 8a side of the lower side 6a, it is directed toward the hook portion 22a as indicated by arrow d, hooked onto the upper side 4a portion of the hook portion 22a, then directed toward another hook portion 28a as indicated by arrow e, made contact with the side 8 portion of that hook portion, and then directed toward the contact portion 30a as indicated by arrow f, making contact with the entire curved portion on the lower side 6a. This forms a single loop 32.

[0025] Similarly, two loops 32 and 34 are formed by winding the fishing line several times. In this state, both loops 32 and 34 are under tension. The finished end of the fishing line 36 is positioned from the contact portion 30a towards the upper edge 4a, as indicated by arrow g in Figure 1. These two loops 32 and 34 are arranged side by side on the flat plate 2, and although these two loops 32 and 34 intersect, the intersection is in contact with the contact portion 30a on the lower edge 6a side. Also, the length of the fishing line 36 between the contact portion 30a and the hook portion 22a is shorter than the length of the fishing line 36 from the hook portion 22a through another hook portion 26a to the contact portion 30a. Similarly, the length of the fishing line 36 between the contact portion 30a and the hook portion 24a is shorter than the length of the fishing line 36 from the hook portion 24a through another hook portion 28a to the contact portion 30a. The contact portion 30a, the hook portion 22a, and another hook portion 26a are located at the vertices of a roughly triangle, and a loop 32 is formed by winding the fishing line 36 between these vertices. The contact portion 30a, the hook portion 24a, and another hook portion 28a are located at the vertices of a roughly triangle, and a loop 34 is formed by winding the fishing line 36 between these vertices.

[0026] The fishing line, pre-wound in this manner, is removed from the winder, and as shown in Figure 1, one loop 32 is positioned between the contact portion 30, the hook portion 22, 24, and the other hook portions 26, 28, with another loop 34 positioned between the contact portion 30, the hook portion 24, and the other hook portion 28. In this state, the fishing line 36 is in a relaxed state and, due to the characteristics of the fishing line 36, it is spread out more than in the state shown in Figure 3. The beginning of the winding is fixed as indicated by the X mark, and the end of the winding is made pullable from the opposite side of the contact portion 30 over the connecting portion 16. In Figure 1, to avoid confusion, both loops 32 and 34 are shown as double loops, and in loop 32, the one closer to the hook portions 22 and 26 is the loop that was wound first, and the one closer to the side edge 8 and boundary line 12 is the loop that was wound later. The same applies to loop 34.

[0027] In this arrangement of the fishing line 36, the intersection of the two loops widens on the lower side 6 of the contact portion 30, and its height from the flat plate 2 is reduced, making it less likely to get tangled.

[0028] To pull out the fishing line 36, pull the finished end of the fishing line 36 towards the top edge 4, as indicated by the arrow in Figure 1. This will unwind the portion of loop 32 on the side edge 8 and the portion of the later wound loop on the boundary line 12. Next, the portion of the loop wound after loop 34 on the side edge 10 and the portion on the boundary line 14 will be unwound. Then, the portion of the loop wound ahead of loop 32 on the side edge 8 and the portion of the loop wound ahead of loop 32 on the boundary line 12 will be unwound, the portion of the loop wound ahead of loop 34 on the side edge 10 and the portion of the loop wound ahead of loop 34 on the boundary line 14 will be unwound. Repeat this process.

[0029] Specifically, when the end of the fishing line 36 is pulled out from the opposite side of the contact portion 30 of the connecting portion 16, the portion of the loop 32 closest to the end of the later-wound loop slides on the thread sliding surface of the contact portion 30, and the portion located near the side edge 8 between the hook portion 22 and the contact portion 30 is unwound and pulled out towards the upper edge 4. As a result, the remaining portion of the loop 32 that was wound after it (the portion from the hook portion 22 near the boundary line 12 toward the contact portion 30) expands. Consequently, the later-wound portion of the loop 34 also expands. However, since the length of the loop portion between the hook portion 24 and the contact portion 30 (the loop on the boundary line 12 side) is different from the length of the loop portion from the hook portion 24 to the contact portion 30 via another contact portion 28 (the loop on the side edge 10 side), the expansion of the loop portion from the hook portion 24 to the contact portion 30 (the portion close to the boundary line 12) is slightly slower than the expansion of the loop portion from the hook portion 24 to the contact portion 30 via another contact portion 28. Therefore, when the portion wound after loop 34 is pulled out, the loop wound at the end of loop 32 has not yet unfolded. While it is still unfolded, the portion wound after loop 34 is pulled out, so it does not get tangled with the portion wound at the end of loop 32 during this pulling process. In the same manner, both loops are unwound one after the other, and tanglement rarely occurs.

[0030] In this embodiment, loops 32 and 34 are doubled to avoid complexity in the drawings, but they can be triple or more. The other hooking parts 26 and 28 can also be removed. The hooking parts 22 and 24 and the other hooking parts 26 and 28 are not limited to hemispherical shapes, but may be of other shapes as long as they have a thread sliding surface.

[0031] As shown in Figures 4 and 5, the thread storage body of the second embodiment of the present invention is constructed by folding the lower plate 18 and the upper plate 20 at the connecting portion 16 so that they overlap parallel to each other. When folded, the heights of the hook portions 22 and 24 from the lower plate 18 and upper plate 20 are adjusted so that they do not come into contact with each other, and similarly, the heights of the other hook portions 26 and 28 from the lower plate 18 and upper plate 20 are adjusted so that they do not come into contact with each other when folded. By folding in this manner, the thread storage body can be made compact. In Figures 4 and 5, the fishing line is omitted. The fishing line is untied in the same way as in the thread storage body of the first embodiment.

[0032] The third embodiment of the thread storage body, as shown in Figures 6 and 7, is the thread storage body of the second embodiment with wing bodies 38 and 40 added. When the lower plate 18 and upper plate 20 are folded so that they overlap, as in the thread storage body of the second embodiment, the distance between the two loops 32 and 34 becomes shorter, and when the fishing line 36 is pulled out, the fishing line 36 untangled in the other loop may occur. To prevent this, it is desirable that most of loop 32 is between the wing body 38 and the lower plate 18, and most of loop 34 is between the wing body 40 and the upper plate 20. For this reason, the hooking parts 22b and 24b are cylindrical, and wing bodies 38 and 40 are provided between the surfaces of these parts opposite to the lower plate 18 and upper plate 20, and between the lower plate 18 and upper plate 20 near other hooking parts 26 and 28. The wing bodies 38 and 40 are formed to protrude somewhat outward near the hooks 22a and 24a, and gradually narrow towards the other hooks 26 and 28, with the length of the edge closer to the boundary lines 12 and 14 being shorter than the length of the edge closer to the sides 8 and 10. The wing bodies 38 and 40 can also be made of, for example, paper.

[0033] When the fishing line 36 is pulled out, it is unwound in the same manner as in the first embodiment, except that it moves along the wing bodies 38 and 40. Furthermore, similar to the thread containment in the first embodiment, the flat plate 2 can also be used without folding.

[0034] The thread storage body of the fourth embodiment, as shown in Figures 8 and 9, is provided with loop retainers 42 and 44 in the third embodiment. The loop retainer 42 is provided on the connecting portion 16 and is located between the wing bodies 38 and 40 when the lower plate 18 and the upper plate 20 are folded to overlap, preventing the fishing line of loop 32 that has come undone from another hooking portion 26 from becoming entangled with another part of loop 32 or loop 34. A side wall 46 is provided on the side edge 8 of the lower plate 18 in the same shape as the connecting portion 16. When the lower plate 18 and the upper plate 20 are folded together, the side wall 46 is folded along the side edge 8. A loop retainer 44 is provided on this side wall 46 in the same way as the loop retainer 42 and is located between the wing bodies 38 and 40 when the lower plate 18 and the upper plate 20 are folded to overlap, and functions in the same way as the loop retainer 42. The part indicated by reference numeral 48 is a fixing part, which is folded so that the lower plate 18 and the upper plate 20 overlap, and the side wall 46 is also folded, and then folded onto the upper plate 20 and fixed to the upper plate 20, maintaining the folded state of the lower plate 18 and the upper plate 20. Note that the loop retainer 42 is provided in common for both loops, but one can be provided for loop 32 near the boundary line 12 on the connecting part 16, and one can be provided for loop 34 near the boundary line 14 on the connecting part 16. The connecting part 42 can also be configured integrally with the contact part 30. Only one of the loop retainers 42 or 44 can be provided.

[0035] The fifth embodiment of the present invention, as shown in Figures 10 and 11, is a thread container that, in the fourth embodiment, is provided with a lid portion 50 and a fixing portion 52. The lid portion 50 is rectangular in shape and is formed continuously with the lower edge 6 of the lower plate 16. When the lower plate 16 and the upper plate 18 are stacked on top of each other, it is folded from the lower edge 6. A rectangular fixing portion is formed on the edge of the lid portion 50 opposite to the lower edge 6, and is fixed on the upper plate 20 to prevent the lid portion 50 from opening. As shown in Figure 11, when the lid portion 50 is folded, it is curved so that the side opposite to the lower plate 18 and the upper plate 20 is convex. With this configuration, when loops 32 and 34 are wound multiple times, the range of movement can be expanded and entanglement of threads within the same loop can be prevented.

[0036] In the sixth embodiment of the present invention, as shown in Figure 14(a), a fishing line 36a that has been pre-wound in a figure-eight shape is bent so that its loops 32a and 34a are aligned, as shown in Figure 14(b), and the line is stretched across so that a hook portion 22 and another hook portion 26 are located within loop 32a, a hook portion 24 and another hook portion 26 are located within loop 34a, and the intersection of the two loops 32a and 34a is located on the lower side 6 of the contact portion 30, as shown in Figure 12. In this embodiment, the contact portion 30 is located on the upper side 4 of the other hook portions 26 and 28. In Figures 13(a) and (b), loops 32a and 34a are shown as single loops to avoid diagrammatic complexity, and the same applies to Figures 12 and 13.

[0037] The boundary line 14 bends the connecting portion 16 so that it is perpendicular to the lower plate 18, and the boundary line 14 further bends the upper plate 20 so that it overlaps the lower plate 18. In this state, as shown in Figure 13, the portion of loop 32a on the boundary line 12 side contacts the connecting portion 16, preventing it from spreading further, and its length is shorter than the portion of loop 32a on the boundary line 8 side. The same applies to loop 34a. Therefore, as in each of the embodiments described above, the thread can be pulled out without entanglement.

[0038] Reference numeral 54 indicates a loop restraint, which is provided between the sides 8 and 10 of the flat plate 2, on the opposite side of the lower edge 6 of the contact portion 30, so as to straddle the two loops 32a and 34a, and is, for example, in an inverted U shape. This prevents the loops 32a and 34a from spreading out due to their elasticity, as they are wound multiple times. Note that the loop restraint 54 is omitted in Figure 13. In the sixth embodiment, wing bodies 38 and 40 can be provided as in the third embodiment, loop retainers 42 and 44 can be provided as in the fourth embodiment, and a cover portion 50 and a fixing portion 52 can be provided as in the fifth embodiment.

[0039] In each of the embodiments described above, the flat plate 2, hooks 22 and 24, other hooks 26 and 28, contact portion 30, wing bodies 38 and 40, loop retainers 44 and 46, and loop restraint body 54 were made of paper, but they can also be made of synthetic resin, and suitable ones can be molded integrally with the flat plate 2.
