BACKGROUND OF THE INVENTION
The present invention relates to a laundry net in which an opening side edge portion of a bag-like net-like fabric is folded and a zipper tape of a slide fastener is sewn on the folded side edge portion.
[0002]
[Prior art]
In a general laundry net, the folded side edge of the opening edge of the net-like fabric is overlapped with the zipper tape of the slide fastener, and the overlapped portion is covered with an edge cloth (bias tape) bent in a substantially U-shaped cross section. Sewing means is used to sew these three together, but the shape of the net-like fabric and the hem itself is weak, so the opening of the laundry net is likely to bend by external force during washing. The laundry thrown into the storage space of the laundry net may be deformed, and it may take time to open and close the slide fastener.
[0003]
Therefore, conventionally, on the inner bottom portion of the edge cloth sewn in a folded shape having a substantially U-shaped cross section with respect to the overlapping portion of the folded side edge portion of the opening edge of the net-like fabric and the zipper tape of the slide fastener. A method of inserting a pipe-shaped shape retaining wire made of synthetic resin having a length over the entire opening of the zipper tape has been proposed (see, for example, Patent Documents 1 and 2).

DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
The laundry net shown in FIGS. 1-6 is other than the side edge part 1a of an opening formation location among the peripheral edges of the plurality of net-like cloths 1 cut into a divided development shape corresponding to the contour shape thereof. The adjacent side edge portions 1b are overlapped with each other folded back inward, and the overlapped folded side edge portions 1b are folded with a narrow edge cloth (bias tape) 2 folded into a substantially U-shaped cross section. Further, the three items of the folded side edge portions 2a of the edge cloth 2 and the folded side edge portions 1b and 1b of the net-like cloth 1 are integrally sewn with the sewing thread 6, thereby washing the laundry. A net bag having a storage space S and an opening A for taking in and out the laundry is constituted.
[0017]
Furthermore, as shown in FIG. 1, the opposite side edge portions 1a at the opening forming portion of the net-like cloth 1 are folded back to the storage space S side. The outer edge portions 3a of the two zipper tapes 3A are overlapped with each other, and on the inner side surface of the outer edge portion 3a of each zipper tape 3A, a plate-like portion 4A that can be curved along the design opening shape of the laundry net The shape-retaining material 4 made of an elastically deformable synthetic resin (for example, soft vinyl chloride, etc.) is formed over substantially the entire opening of the slide fastener 3 in a posture along or substantially along the tape surface direction of the zipper tape 3A. Further, the overlap portion is covered with an edge cloth (bias tape) 5 which is folded in a substantially U-shaped cross section, and the edge cloth 5 in a superposed state of seven layers as a whole is folded back. The side edge portion 5a, the folded side edge portion 1a of the net-like cloth 1, the outer edge portion 3a of the zipper tape 3A, and the shape retaining material 4 are integrally sewn with the sewing thread 6.
[0018]
The shape-retaining material 4 is slightly shorter than the entire length of the zipper tape 3A, and is slightly shorter than the total length of the zipper teeth 3B formed along the inner edge of the zipper tape 3A (corresponding to the entire opening length of the slide fastener 3). The shape is long and the cross-sectional shape of the shape-retaining material 4 is formed into a substantially triangular shape that tapers toward the outer zipper teeth 3B side.
[0019]
Therefore, the shape retaining function at the opening of the laundry net is achieved by the synthetic resin shape retaining material 4 sewn at the sewing location between the folded side edge 3a of the net-like fabric 1 constituting the net bag and the zipper tape 3A. As a result, the shape of the opening of the laundry net is maintained as much as possible in the initial design opening shape even during washing, so that the laundry can be prevented from being deformed and the opening / closing operation by the slider 3C of the slide fastener 3 can be facilitated. It can be planned.

FIG. 7 shows another embodiment of a shape-retaining material 4 made of an elastically deformable synthetic resin attached to a sewing portion between the folded-back side edge portion 1a of the net-like cloth 1 and the zipper tape, which is a zipper tape 3A. The plate-like portion 4A having a posture along or substantially along the tape surface direction and a cylindrical portion 4B integrally formed on the side facing the storage space S side, and a cross section of the plate-like portion 4A The shape is formed in a substantially triangular shape that tapers toward the zipper tooth 3B side that is the outer surface side.
[0024]
Then, the slide fastener 3 that has been opened is easily pushed and opened in a direction X perpendicular to the opening / closing operation direction of the slider 3C when the laundry is put in and out by one plate-like portion 4A constituting the shape retaining material 4. While being able to be operated, the opening shape of the laundry net is changed to the initial design opening shape by the plate-like portion 4A and the cylindrical portion 4B integrally formed on the side facing the storage space S. Although it can be maintained as much as possible, in particular, the presence of the cylindrical portion 4B can increase the elastic restoring force when the opening of the laundry net is bent.
