Japanese Utility Model Publication No. 54-154145

  The shape holder according to Patent Document 1 can obtain a temporary effect in terms of reinforcing the scallops themselves. However, when only the wire or thin plate of plastic metal (aluminum or tin-lead alloy, etc.) is used as the main body of the shape holder, not only the appearance is bad, but there is a risk of damaging the fingers during handling. there were. Also, according to the use mode of the sandals, since various loads resulting from the weight and sudden movement of the wearer are applied to the shape holder, for example, in a specific place such as the center in the longitudinal direction in the shape holder body, Due to repeated bending, the wire may be cut or cracks may occur in the thin plate, resulting in a decrease in durability and a risk of the sharp part protruding from the wearer's foot being pierced. It was.

  In order to alleviate these drawbacks, Patent Document 1 discloses a patch-shaped shape holder composed of two carrier sheets (vinyl tape) bonded with the metal wire interposed therebetween and an adhesive layer. ing.

  However, even in the case of a patch-shaped shape holder composed of two carrier sheets and a glue layer that are bonded together with a metal wire interposed therebetween, the wire or thin plate is protected by the two carrier sheets. Although the durability is somewhat improved, when it is consumed, the cut part in the case of a wire rod and the sharp edge part in the case of a metal plate may be exposed to the outside through the carrier sheet and band forming fabric. In the same manner as in the case where the carrier sheet is not covered, there is a risk that a sharp portion pierces the foot.

  Furthermore, the use of these metal materials has the disadvantage that the weight of the sandals increases and the burden on the wearer increases during walking.

  For this reason, in recent years, the shape holder is made of a synthetic resin and is covered with a carrier sheet. Here, since the shape holder is used by being polymerized with respect to a band member such as a backband member, it is required to have an extremely thin shape, and in the case of a synthetic resin, it has a rebound resilience. Therefore, particularly in the case of a thin plate made of synthetic resin, the resilience elasticity becomes very large, and the shape holder made of synthetic resin cannot be used practically, and only a wire made of synthetic resin is used. It is manufactured as the shape holder used.

  In this way, by using the synthetic resin wire, sandwiching the wire with two carrier sheets, and making a patch-shaped shape holder having a glue layer, the rebound resilience of the synthetic resin is reduced, It is possible to realize a temporary plastic deformation. However, if the shape holder requires an extremely thin shape, the outline of the wire sandwiched between the two carrier sheets deforms the carrier sheet and stores it in the sandal band. Has a defect that causes the appearance of a bowl to be raised and the appearance appearance to be poor.

  The present invention has been made in view of the above circumstances, and the safety of the wearer can be sufficiently realized without exposing the sharp edge of the metal member, and there is no rebound resilience and sufficient. By obtaining the shape-retaining effect, it is possible to maintain a good shape-retaining property at the time of product display, etc., and to obtain an optimal shape that is comfortable to the wearer, and the surface of the band also has a wire material.
