  The present invention provides a sandwiching tool manufacturing sheet and a sandwiching tool with good handleability when handling various objects in between.

  The pincer preparation sheet of the present invention is a sheet for manufacturing a pinch tool that is folded into a finished shape, and the pinch portion of the sheet has a linear hinge fold, and both side portions thereof are The folds are symmetrical to each other, the hinge folds are hinges, and both side portions thereof are a pair of arm portions, and each arm portion folds the side edge portion for each side edge of itself. And each side edge of each arm part is in a shape along a straight line, and the shape drawn by the side edge fold is an arc shape, and at the same time, the shape that goes out from the side edge on the base side of each arm part and sinks to the side edge on the tip side It is.

In addition to the above-described configuration, the sandwiching device manufacturing sheet according to a preferred aspect includes a front end fold for each arm portion to fold a front end portion (arm portion front end surface portion 33) on its front end side. The shape to be drawn is a shape that hangs between the side edge folds facing each other and simultaneously swells in an arc shape toward the inside.
Moreover, the sheet | seat for pinch tool preparation of a preferable aspect is a thing with an intermittent crease | fold in addition to the said structure, and the cut | interruption is formed in the interrupted part.

The sandwiching tool of the present invention is obtained by folding the sandwiching member manufacturing sheet having the above configuration at a crease.
The sheet material used in the present invention is not particularly limited as long as it can form a crease such as paper, paper coated or impregnated with synthetic resin, synthetic resin sheet, biodegradable resin sheet, etc. Those having biodegradability such as a functional resin are preferred.

  The clip making sheet of the present invention has a shape in which each side edge of each arm portion is along a straight line, and is arc-shaped and at the same time a shape that protrudes from the side edge on the distal end side of the arm portion and sinks to the side edge on the root side. Because the side folds are folded, the arm part completed by bending becomes a spoon shape, and the side edges and the end edges of both arm parts face each other with almost no gap when the completed clip is closed become. Therefore, the pinching tool of the present invention can handle relatively large objects by directly pinching them, and relatively small objects and soft objects can be scooped and taken into the space of the arm part to be moved and transported. can do. Moreover, if a biodegradable material is used as the sheet material, the object can be sandwiched and discarded in the garbage bag.

  Further, in the case where the tip portion (arm tip surface portion 33) is bent by the tip crease, the arm portion completed by bending becomes a deeper spoon shape, and handling of a small object or a soft object becomes easier.

In addition, when the folds are intermittent and have breaks at the discontinuous portions, the fold when the clip is completed is easy and the shape of the completed clip is kept long.
Further, the clipper completed by bending the clipper preparation sheet described above has good handleability when pinching or scooping an object.

  The pincer of the present invention is completed by bending at a plurality of creases provided on the pincer preparation sheet, and the material of the sheet is paper, paper coated or impregnated with synthetic resin, synthetic resin Although it will not specifically limit if a crease | fold can be formed, such as a sheet | seat and a biodegradable resin sheet, Materials, such as paper and biodegradable resin, are preferable. The hardness of the material is preferably 200 to 10,000 MPa in terms of tensile modulus (Young's modulus), and the sheet thickness is set to an appropriate thickness depending on the size of the clip, but the length of one arm is 20 cm or less. If so, 0.3 to 1.0 mm is preferable. If the size is more than 20 cm, the thickness may be proportionally increased according to the length of the arm.

Hereinafter, the present invention will be described in detail with reference to the pinch of the embodiment. In addition, the sheet | seat 1 for pinch implement preparation of an Example was produced using the sheet | seat which apply | coated synthetic resin to the paper of thickness 0.6mm and unit weight 370g / m < ² >.

  FIG. 1 shows a developed shape of the clip making sheet 1. Further, FIGS. 2 and 3 show a sandwiching tool produced by bending the sandwiching tool producing sheet 1. In FIG. 1, a dotted line represents a fold line, and a solid line represents a cut line. Each crease may be continuous or intermittent along the crease. Further, the crease can be formed by a known method such as press shaping by a press device, half cut processing, perforation processing, and the cut can be formed by a known method such as cut processing by a press device. .

  The pincer preparation sheet 1 is configured to form a hinge 2 and a pair of arm portions 3 on both sides of the hinge by a hinge crease 4. The direction of the hinge crease 4 is parallel to the width direction. Both arm portions 3 are line symmetric with respect to the hinge crease 4.

  The developed shape of each arm 3 is preferably a quadrilateral shape, but more preferably is an isosceles trapezoidal shape with the tip edge as the base (see FIG. 1). In addition, although it is preferable that the front end side is wider than the base side, the front end side and the base side may be the same, and the front end side may be narrower than the base side.

  The sandwiching tool manufacturing sheet 1 is configured to form the arm portion main body surface portion 31 and the arm portion side edge surface portion 32 by bending at the side edge fold line 5. The shape drawn by the side edge crease 5 is an arc shape and a shape that goes out of the side edge on the base side of each arm portion and sinks to the side edge on the tip side while gradually increasing its curvature. The side edge crease 5 is spaced apart from the hinge crease 4 on the base side, and reaches the corner formed by the side edge 10 and the tip edge 11 on the tip side. The side edge 10 has a wave shape at the front end side, but has a shape along a straight line over the entire length. With the above configuration, the arm portion 3 having a completed shape may have a curved shape in which the arm portion main body surface portion 31 bulges outward in the longitudinal direction, and the whole is a spoon shape (see FIG. 2). Further, when the completed clip 1 is closed, the side edges 10 and the tip edges 11 of both arm portions face each other with almost no gap (see FIG. 3).

  Further, in the clip making sheet 1, a tip fold 6 is formed on the tip side of the arm portion 3, and the arm portion tip surface portion 33 is formed on the tip side of the arm portion main body surface portion 31 by bending at the tip fold 6. It comes to form. The shape drawn by the tip crease 6 is such that it extends between the side edge creases 5 facing each other and swells in an arc shape toward the inside. With the above configuration, the arm portion 3 having a completed shape has a curved shape in which the arm portion main body surface portion 31 swells outward in the width direction, and thus has a deeper spoon shape as a whole (see FIG. 2).

  When the crease is intermittently formed at the crease forming portion, it is preferable to provide a cut that connects adjacent creases at the discontinuous portion. Such a cut is effective in reducing the stress generated when the clip is completed, and more specifically, it is easy to bend and complete the clip when the clip is completed. Work to keep the shape of the long.

  In the clip making sheet 1, a continuous fold is formed by the second fold 5 and the cut 71, and a continuous fold is formed by the third fold 6 and the cut 72 (see FIG. 1). Further, the cut 71 is shaped to bulge outward, and the cut 72 is shaped to bulge inside. In the clip 1 completed by providing the cut 71 and the cut 72, the claw-like portion 12 that goes to the outside is formed by the cut 71, so that it becomes a non-slip when held by hand, and the claw-like shape that goes inside by the cut 72. Since the part 13 is formed, the operation of scooping the object is easy (see FIG. 2).

  Further, in the clip making sheet 1, a hinge spring portion 9 for biasing the completed clip 1 in the opening direction is formed in the hinge 2 portion. The hinge spring portion 9 includes two parallel cuts 73 perpendicular to the hinge fold 4 and two second hinge folds 8 parallel to the hinge fold with the hinge fold sandwiched between the two cuts 73. It is composed. The hinge fold 4 is folded into a mountain fold to form the hinge 2, but the hinge fold 4 in the hinge spring portion 9 is folded into a valley fold to form the hinge spring portion 9 (see FIG. 3).

  Further, in the sandwiching tool manufacturing sheet 1, the distal end side and the distal end edge 11 of the side edge 10 are formed in a wave shape to make it easier to sandwich the object. Further, a plurality of main body folds 14 parallel to the width direction are formed on the arm main body surface portion 31 to facilitate the folding at the side edge folds 5 and handle the clamping tool by the unevenness of the main body folds themselves. The time slip function is put out.

  The dimensional relationship of the clip making sheet 1 is preferably as follows from the viewpoint of handleability. In other words, in the dimension of the developed shape, the relationship between the width of the leading edge of the arm part and the length of the arm part on one side is 1: 1.5 to 1: 2.5, and the width of the arm part side edge surface part 32 is maximized. The relationship between the width of the arm portion side edge surface portion 32 on one side and the width of the arm portion at the position is 1: 4 to 1: 7, and the relationship between the width on the arm portion base side and the width on the tip end edge side of the arm portion is 1: 1 to 1. It is preferably 1: 2. Moreover, when using pet feces as a target, the length of the one-side arm is preferably 10 to 20 cm. The length of the one side arm part of an Example is 13 cm.

  As mentioned above, although this invention was demonstrated with reference to the sheet | seat 1 for pinching tool preparation of an Example, this invention is not limited to the pinching tool of an Example, For example, "The part used as the pinching tool of a sheet | seat is. A shape having a straight crease and its both side portions symmetrical with each other means that the side edge and the leading edge of one arm are wavy, and the side and leading edges of the other arm are straight. Even if there is a certain degree of difference, that is, a difference that does not affect the operation and effect of the invention, this is included.
