  However, since the above-mentioned conventional core materials for scissors are all made of a plate-like body, they are hard and difficult to cut into regular shapes, and when used in large amounts for scissors, the weight increases and the core material should be used. As a result, the weight of the bag increases.

  Furthermore, since the above conventional cores for scissors are all made of a smooth plate-like body, even when sandwiched between thin portions such as a shoulder belt, they can move and shift inside. In particular, when sandwiched between wide parts such as the body, bottom, and lid of the heel body, there is a problem that it will not be able to be mounted accurately at the position where it is to be mounted. Was.

  In addition, the above conventional bag core material is made of a smooth plate-like body even if an adhesive is used to attach it accurately to the position where it is to be attached, so it is difficult to adhere to the shoulder belt or bag body, and it is desired to attach it. There is a problem that positioning to a position is difficult.

  Therefore, the present invention solves the above-mentioned conventional problems, and even if it is used in large amounts for the heel, the weight of the heel does not increase, and positioning to the position where the heel is to be attached is simplified, and the position where the eager is desired to be attached. The purpose of the present invention is to provide a bag core material that can be accurately attached to the bag.

The shoulder belt of the present invention includes a core material in which a linear shape-retaining resin is woven in a mesh shape and fixed by heat welding, and an exterior fabric that sandwiches the core material. The core material is fixed to the exterior fabric.

Furthermore, in the shoulder belt of the present invention , the core material includes mesh holes. The back belt further comprises an adhesive applied to reach the mesh holes. Further, in the above-mentioned backpack belt, the core material is sewn to the exterior fabric.

  Since the core material for scissors according to the present invention is configured as described above, the weight of the scissors does not increase even if it is used in many scissors, and positioning to the position where the scissors are to be attached is simplified. It can be accurately attached to the position where it is desired to be attached, and is suitable for use in various types of scissors.

  Hereinafter, the best mode for carrying out the core material for scissors according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the bag core M of the present invention is made of a linear shape-retaining resin 1 woven in a mesh shape and fixed by heat welding so that it can be cut into a fixed shape.

  The shape-retaining resin 1 is a linear body having a substantially circular cross section with a diameter of about 0.3 to 1 mm, and has one or a plurality of bundles to have mesh holes 2 of about 0.5 to 2 mm square. And woven into a mesh.

  In the present invention, the shape-retaining resin 1 is made of a plastic resin that has shape-retaining properties and can be plastically deformed. When bent with fingers, the shape-retaining resin 1 can be bent at an arbitrary angle, and further has a bending force at different bending angles. Until it is added, it can hold its bent shape as it is. As such a thing, there is what is obtained by extending polyolefin at high magnification in a uniaxial direction. For example, raising “Forte” (trade name) which is a shape-retaining material made of synthetic resin made by Sekisui Chemical Co., Ltd. However, it is not limited to this.

  The bag core material M of the present invention can be cut into a fixed shape by adopting the above-described configuration. For example, as shown in FIGS. 2 to 4, the user's body of the backpack belt B of the school bag R The shape of the shoulder belt B can be deformed to at least a part of the portion in contact with the belt, and can be attached to the shoulder belt B.

  That is, as shown in FIGS. 2 and 3, the bag core material M of the present invention sandwiches a cushion material 4 such as a synthetic resin between exterior fabrics 3 (front fabric 3 a and back fabric 3 b) such as synthetic leather. After cutting into a shape corresponding to the substantially upper half of the upper belt B1 of the shoulder belt B, applying an adhesive and sandwiching it between the exterior fabric 3 and the cushion material 4, they are put together. It is assumed that it is fixed by sewing.

  Further, as shown in FIGS. 2 and 4, the bag core M of the present invention is formed on the lower belt B2 of the shoulder belt B made of the exterior fabric 3 in which the front fabric 3a and the back fabric 3b such as synthetic leather are overlapped. After cutting into a shape substantially corresponding to the whole, applying an adhesive, and sandwiching and positioning between the front fabric 3a and the back fabric 3b, these are bundled together and fixed with the scissors 5.

  In this case, since the heel core material M of the present invention is woven in a mesh shape, the frictional resistance increases, and between the exterior fabric 3 and the cushion material 4 or between the front fabric 3a and the back fabric 3b. It becomes difficult to slip when sandwiched, and positioning is easy. Furthermore, in the core material M for scissors according to the present invention, the adhesive applied to the shape-retaining resin 1 spreads over the texture and the mesh holes 3, and the contact area between the shape-retaining resin 1 and the shoulder belt B becomes wider and solidifies. Adhesive strength is increased and positioning is easy.

  As shown in FIG. 5, the backpack belt B of the school bag R to which the collar core M of the present invention is attached as described above has the shape of the portion to which the collar core M is attached to the body of the user. It adjusts so that it may surface-bond so that a clearance gap may not be produced, ie, the whole width may surface-bond to a user's body.

  In order to adjust the shoulder belt B in this way, the portion of the upper belt B1 of the shoulder belt B that contacts the user's shoulder to the chest is bent according to the curved shape from the user's shoulder to the chest, and the folding is performed. In this case, the outer edge of the lower belt B2 of the shoulder belt B is bent so that the outer edge of the lower belt B2 approaches the flank of the user, and the bent shape is maintained.

  Then, when the school bag R having the shoulder belt B adjusted in this way is carried on the back, as shown in FIG. 6, at the position of the user's shoulder or the position from the user's flank to the chest, the shoulder belt B The entire width of the belt is bonded to the surface, and the shoulder belt B fits the user's body.

  Further, the bag core material M of the present invention is woven in a mesh shape and is very light. Therefore, the shoulder belt B is also lightened, and the user of the school bag R is burdened in terms of weight. It will not be. Note that the bag core M of the present invention is applied to the backpack belt B of the school bag R as in the above-described embodiment, but if it is made of a conventional flat plate-like body, the backpack belt B The heavier school bag R becomes heavier, and the heavier school bag R becomes heavier, which places a heavy burden on the schoolchild who is the user.

  Moreover, although the core material M for scissors of this invention may be used for the whole trunk | drum and bottom part of a scissors main body, it does not affect the weight of the scissors in such a case, but a sputum is so heavy. Can be nothing. However, in the conventional core material made of a flat plate having a smooth plate-like body, the weight of the bag is considerably affected, and the bag becomes very heavy.
