In the thread case where the recesses (63) of 61) and (62) face each other, one place of both flanges (64A) (64B) is connected by uneven fitting (65). On the other hand, the flanges (64A) and (64B) on opposite sides of the recess (63) of both members (61) and (62) were connected by the eyelets (66). Further, a mounting portion (68) of a cutter (67) is formed at an edge of the flange (64A) adjacent to the eyelet (66) of one of the case constituent members (61), and a tip of the mounting portion (68) is formed. Also, a V-shaped notch (69) is provided on each of the flanges (64B) of the other case constituent member (62) opposed thereto, and the thread is cut by a cutter (67). Further, a V-shaped notch (71) for thread fastening was formed in the flanges (64A) (64B) facing the cutter (67) with the eyelet (66) interposed therebetween.

[0003]

[Problems to be solved by the invention]

 However, in the above-described yarn case, it takes time and effort to connect the overlapped flanges (64A) and (64B) of the two case constituent members (61) and (62) by the eyelet (66), and the eyelet eyelet. Tools for forming (66) are also required. In addition, since it is necessary to form the mounting portion (68) of the cutter (67) on the flange (64A) of the one case constituent member (61), there is a problem that the manufacture of the case is troublesome.

 The invention according to claim 1 comprises a pair of case components having a recess for accommodating approximately half of the thread winding and an outward flange provided at the opening edge of the recess. In the case of a thread in which the recesses of both members are opposed to each other and one of the two flanges is opposed, one of the two flanges is fitted with a fitting concave portion provided on one of them and a fitting convex portion provided on the other. Flange extension protrusions are provided at the edges of the two flanges on the opposite side of the joint between the two joints, with through holes in the flange extension protrusions. The two flange extension protrusions are adapted to be inserted into recesses of a thread cutter having a thread cutter, and both side edges of the recesses have two bridge-like portions opposed to each other. The ends are connected A protrusion is provided on the inner surface of one bridge-like portion, and two adjacent protrusions are provided on the inner surface of the other bridge-like portion. A gap is provided for the protrusion of one bridge-like portion. The flange extension protrusion of the case component passes through the gap between the two bridge-like portions of the thread cutter and is inserted into the recess of the thread cutter, and the one bridge-like portion of the thread cutter is inserted into the through hole of both flange extension protrusions. The projection is inserted into the gap between the other bridge-like portions, the two flange extension protrusions are connected to each other, and the thread cutter is attached to the both flange extension protrusions.

According to a second aspect of the present invention, in a yarn case in which flanges for holding a yarn are provided at both ends of a winding core around which the yarn is wound so as to face each other, an outer surface of one of the flanges protrudes from the portion. There is provided a flange extension convex portion comprising a first projecting wall portion and a second projecting wall portion extending upward from the tip of the first projecting wall portion, and a through hole is formed in the second projecting wall portion of the flange extending projecting portion. The second protruding wall portion of the flange extension convex portion is adapted to be inserted into a concave portion of a thread cutter having a thread cutter, and two opposite bridging portions are provided on both side edges of the concave portion. The end of the bridge is formed with a protrusion on the inner surface of one bridge, and the inner surface of the other bridge is composed of two adjacent protrusions, and the protrusion of one bridge enters. A gap is provided, and the second protruding wall of the flange extension protruding portion is formed as a double bridge of a thread cutter. The thread cutting tool is inserted into the recess of the thread cutting tool through the gap between the portions, and the projection of one bridge-like portion of the thread cutting tool is inserted into the gap of the other bridge-like portion in the through hole of the second protruding wall portion. A thread cutter is attached to the extension convex part.

[0007] In any of the above-described yarn cases, the tip surfaces of the projections of both bridge-like portions are formed as rearwardly inclined surfaces, and by pushing the flange extension convex portion along the inclined surfaces, It is preferred that both bridges bend outwardly so that the flange extension passes between the protrusions and that both bridges are elastic and return to their original shape. Preferably, the thread trimmer also has a threading cut for stopping the end of the thread.

According to a fifth aspect of the present invention, there is provided a thread cutter having a recess into which a flange extension of a thread case is inserted, and ends of two bridge-like portions facing each other are connected to both side edges of the recess. A protrusion is provided on the inner surface of one bridge-like portion, and two adjacent protrusions are provided on the inner surface of the other bridge-like portion, and a gap is provided for receiving the protrusion of one bridge-like portion. It is something that is.
