(First embodiment)
First, a first embodiment of a cover manufacturing method and a cover according to the present invention will be described with reference to FIGS.

  The cover 10A manufactured by the cover manufacturing method of the present embodiment is used as a part of the cover material Cv of the substantially rectangular parallelepiped cushion Cu shown in FIG. As shown in FIGS. 1 and 2, the cushion Cu includes a content M such as urethane foam, and a cover material Cv that covers the content M.

  The cover material Cv includes the cover 10A of the present embodiment that covers the front surface, the upper surface, and the rear surface of the content M, the left and right side covers Cs that cover the left and right side surfaces of the content M, and the lower surface cover Cb that covers the lower surface of the content M. . Note that the cover 10A, the left and right side covers Cs, and the lower surface cover Cb are joined together by sewing, adhesion, welding, or the like.

  As shown in FIG. 3, the cover 10 </ b> A of the present embodiment includes a skin material 20 and a slide fastener SF that closes an opening 21 of the skin material 20. The skin material 20 and the slide fastener SF are integrally fixed by insert molding. Further, the slide fastener SF is continuously arranged over the front surface, the upper surface, and the rear surface of the cushion Cu.

  The skin material 20 is a thin plate member having elasticity, and examples of the material thereof include silicon resin and latex. The skin material 20 of the present embodiment is obtained by cutting one skin material into left and right two sheets, and an opening 21 is formed by the opposing edge portions 22 of the two left and right skin materials 20. The skin material 20 penetrates into the surface irregularities (texture) made of the woven structure of the fastener tape T, and the surface irregularities (knitting) made of the knitted structure, and is fixed integrally with the slide fastener SF. The material of the skin material 20 is not limited to silicon resin and latex, and may be any material as long as it has flexibility and stretchability.

  As shown in FIG. 3, the slide fastener SF includes a pair of fastener tapes T and fastener elements E that are respectively attached to opposing tape side edges Ta of the pair of fastener tapes T. The fastener tape T is woven or knitted. The fastener element E is a coil-like fastener element in the present embodiment, but may be a zigzag fastener element, a metal fastener element, or a synthetic resin fastener element. The slide fastener SF may be a hidden type slide fastener. Further, the slide fastener SF of the present embodiment does not include a slider for engaging and separating the left and right fastener elements E, but may include a slider.

  As shown in FIG. 3, the slide fastener SF is disposed inside a pair of edge portions 22 constituting the opening 21 of the skin material 20. The fastener element E is disposed on the side away from the skin material 20 of the fastener tape T. The end edge of the tape side edge portion Ta of the fastener tape T is arranged flush with the end edge of the edge portion 22 of the skin material 20. When the slide fastener SF is closed (when the left and right fastener elements E are engaged), the pair of edge portions 22 of the skin material 20 are joined. In other words, among the pair of fastener tapes T having the front surface and the back surface, the fastener element E is attached only to the back surface side. Further, the inner surface of the skin material 20 and the front surface of the fastener tape T are fixed to each other so that they face each other. When the slide fastener SF is closed (when the left and right fastener elements E are engaged), the end surfaces of the pair of edge portions 22 of the skin material 20 are in surface contact with each other.

  As shown in FIG. 4, the cover manufacturing method of the present embodiment includes a mold preparation step ST1 for preparing a mold D for forming the cover 10A, and a fastener arrangement process ST2 for arranging a slide fastener SF in the mold D. (See FIG. 5), a material supply step ST3 (see FIG. 6) for putting the liquid skin material L to be the skin material 20 in the mold D, and solidifying the skin material L into the skin material 20, An integration step ST4 for fixing the slide fastener SF integrally, a mold release step ST5 for removing the molded cover 10A from the mold frame D, and the skin material 20 of the cover 10A removed from the mold frame D along the slide fastener SF. And an incision step ST6 for forming an opening 21 by cutting.

  As shown in FIG. 5, the mold frame D is a bottomed quadrangular member, and includes a recess D <b> 1 in which the left and right fastener elements E of the slide fastener SF can be arranged at the center in the left-right direction. The recess D1 is formed by disposing two plate materials D2 on the bottom surface of the mold D with a predetermined interval. In the recess D1 of the mold D, the left and right fastener elements E of the slide fastener SF are placed in the fastener placement step ST2. The left and right fastener elements E are disposed in the recess D1 in a state of being engaged with each other. Further, the mold D and the plate material D2 are preferably made of metal, and may be a mold. Moreover, although the formwork D of this embodiment is an open type which the upper part is open | released, a sealing type provided with a cover material may be sufficient. Further, the mold D and the plate material D2 may have a complicated uneven shape according to the shape of the product to be manufactured. In addition, the recess D1 is, for example, in a state where the width dimension of the recess D1 is slightly narrower than the width dimension of the left and right fastener elements E, and the left and right engaged fastener elements E are fitted (press-fitted) into the recess D1. The fastener element E may be disposed.

  In the material supply process ST3 and the integration process ST4, the liquid skin material L is placed in the mold D in which the slide fastener SF shown in FIG. The material 20 and the slide fastener SF are integrally formed.

  As the liquid skin material L, a thermoplastic resin, a volatile curable resin, a two-part curable resin, a resin that cures when exposed to air, or the like is used, but a silicon resin (two-part curable resin) or latex (in the air). Resins such as a resin that cures when touched are preferred.

  The liquid skin material L poured into the mold D is deposited so as to cover the slide fastener SF arranged in the mold D. The deposited liquid skin material L has a flat surface due to gravity. After being poured to the required thickness of the skin material, it is allowed to stand until it is cured for a predetermined time. In addition, after pouring the liquid skin material L, the pressing plate which is not shown in figure in the mold D may be installed on the liquid skin material L, and the liquid skin material L may be hardened.

  At this time, the liquid skin material L adheres to the surface of the fastener tape T. The pair of fastener elements E is not soiled by the liquid skin material L by the recesses D1 and the fastener tape T. Here, there may be a slight gap between the opposing surfaces of the pair of fastener tapes T, but this gap may be a gap that does not allow the liquid skin material L to enter.

  After the hardening of the liquid skin material L is completed, the skin material 20 integrally formed with the slide fastener SF is taken out from the mold D (mold release step ST5). Finally, in the hardened skin material L, the skin material 20 is opened with an acute blade along the opening / closing line of the slide fastener SF (line along the opposing surface of the pair of fastener tapes T). Form.

Moreover, the skin material 20 and the slide fastener SF can be shown integrally, and the cover 10A with a novel design property can be provided.

  Further, according to the cover manufacturing method of the present embodiment, since the opening 21 is formed by making a cut in the skin material 20 of the cover 10A, there is almost no unevenness at the joint of the opening 21 of the skin material 20, and the cover surface Can be flat. In the cover described in Patent Document 1, since the skin material is folded inward, large unevenness is generated at the joint of the skin material.

  Further, according to the cover 10A of the present embodiment, when the fastener tape T is woven or knitted, the surface of the fastener tape T is uneven due to the texture or stitch structure, so that the liquid skin material L is a fastener. The skin material 20 and the slide fastener SF are integrally fixed by being bonded to the weave or stitch of the tape T. For this reason, the process of sewing the slide fastener SF to the skin material 20 can be eliminated, and the manufacturing cost can be reduced. Moreover, the skin material 20 and the slide fastener SF can be shown integrally, and the cover 10A with a novel design property can be provided.

  Further, according to the cover 10A of the present embodiment, when the end edge of the tape side edge portion Ta of the fastener tape T is arranged flush with the end edge of the edge portion 22 of the skin material 20, and the slide fastener SF is closed. Since the pair of edge portions 22 of the skin material 20 are joined to each other, the unevenness is not substantially generated at the joint of the opening 21 of the skin material 20, and the cover surface can be made flat.

  According to the cover 10A of the present embodiment, the slide fastener SF may be opened and closed using a slider (not shown), but the pair of fastener elements E may be engaged without using the slider. As a method of meshing without using a slider, for example, meshing is preferably performed by a method described in PCT / JP2015 / 083940. That is, as shown in FIG. 7, a rigid member Ma having a concave groove Ma1 is extended along the surface of the contents M, and the pair of fastener elements E are concave grooves when inserted into the concave groove Ma1. The heads of the fastener elements E are meshed with each other by moving in the direction of meshing with each other by the inner wall of Ma1. In addition, the meshing method of the elements which do not use the slider using the technology of PCT / JP2015 / 083940 can be applied to each embodiment described later.
