JP 2006-131250 A

  When carrying a bag without twisting an arm, a cloth bag, for example, a tote bag, has a saddle face in the front-rear direction of the person who carries it, whereas a conventional shopping bag has a saddle face in the lateral direction of the person who carries it. Was. Due to the structure as described above, when carrying a shopping bag by hand, it is necessary to twist the arm about 90 degrees to change the direction of the heel face in the front-rear direction of the human body. In addition, the use as a shoulder bag to be carried around the shoulder is a structure in which the arm is passed from the side of the narrow side, which is the narrower side, so the bag protrudes greatly from the body, making it unstable and virtually impossible to carry on the shoulder Met. In addition, the bag was not seated well and the handle protruded upward from the bag portion, so that the cashier was not able to directly pack the products that had been set in the cash register and settled. In the present invention, the problem as described above is solved.

  The forming structure of the handle is the same as that of a conventional shopping bag. To describe the structure, the surface of the rectangular tube-shaped saddle face is valley-folded into a V shape, and the upper side of the rectangular tube shape that is folded linearly is used. Joining to form a joining ridgeline, cutting the central part of the joining ridgeline and the V-folded upper region of the collar surface to form a suspension hole, and by forming the suspension hole, the top of the V-fold belt A handle is formed with a ridgeline. The bottom of the rectangular tube is closed to form a bag portion, and the bottom surface of the bag portion forms a rectangular bottom wall. The long bottom side of the bottom wall is provided in a positional relationship that intersects the fitting ridge line at a right angle.

  Because the long bottom side of the bottom wall is provided in a position that intersects the attachment ridge line of the handle at a right angle, the suspension hole formed by the attachment of the attachment ridge line is located on the long bottom side and carries the bag Since the long base is in contact with the human body, there is no need to twist the arm and carry it, and it can be hung on the shoulder in a stable state as a shoulder bag. Since the bag part is opened by expanding the upper part of the bent wall at the upper part of the short bottom side of the bottom wall to open the bag part, the handle will fall outside by spreading the hem of the handle, and set next to the cash register in a state where the handle does not get in the way The cashier can directly pack the items that have already been paid.

It is a perspective view of a placement state. Example 1 It is the perspective view which showed the long bottom side formation process. FIG. It is a front perspective view of a folded state. It is a folding state principal part see-through | perspective peeling front perspective view. (Example 2) It is a principal part perspective view which shows a winding process. It is a perspective view which shows a tatami paper folding process.

  By positioning the long bottom side of the bottom wall in a direction perpendicular to the attachment ridgeline of the handle, we realized a plastic bag that can be held by hand without twisting the arm, shouldered in a stable state, and set next to the cash register.

  FIG. 1 is a perspective view of a set state. The broken line is displayed as a one-dot chain line, the perspective line is displayed as a broken line, and the broken line direction displayed in the valley folded mountain fold is displayed with reference to the outside. The surface of the hanging wall 1 is the front surface, and the surface of the bent wall 2 is the side surface. The forming material of the present invention is not limited, and may be cloth, non-woven fabric or paper, but is preferably an artificial resin film, and the artificial resin film may be vinyl, but polyester (hereinafter referred to as poly It is desirable that

  A bent tube 2 having a pair of facing surfaces is extended to both sides of a suspension wall 1 having a pair of facing surfaces to form a rectangular tube, and a rectangular bottom wall 4 is connected to the bottom of the rectangular tube to form a bag portion 3. To do. A handle 5 is extended to the upper part of the hanging wall 1, and the handle 5 is formed by joining the tops of the V-shaped bands 6 that are folded on the outside. To do. The bonding method is not limited, and may be bonding, stitching, or fitting in some cases. However, since a poly material is desirable, welding is desirable as a desirable bonding method for the poly material. The welding is a processing method in which an artificial resin material such as poly or vinyl is temporarily melted and hardened at a place where a high-frequency sewing machine or an ultrasonic sewing machine is connected. A region connecting the center of the ceiling edge of the suspension wall 1 to the inside of the attachment ridge line 7 is cut to form a suspension hole 15, and the handle 5 forms a ring shape by the formation of the suspension hole 15. The bending line 12 is inserted by a folding line that penetrates the center of the bending wall 2 to the top and bottom. A knot 14 is provided by projecting the center of the top edge of the bent wall 2 in the celestial direction.

  The bottom wall 4 forms a rectangle with a long bottom side 8 and a short bottom side 16, and the bottom side of the suspension wall 1 is a long bottom side 8 and the bottom side of the bent wall 2 is a short bottom side 16. Since the short bottom side 16 and the joining ridge line 7 form a parallel positional relationship, the extended line of the long bottom side 8 and the joining ridge line 7 forms a positional relationship intersecting at a right angle.

  FIG. 2 is a perspective view showing a long bottom side forming process. The forming method of the handle 5 is preferably the same as that of the conventional shopping bag, and the forming method will be described below. A region penetrating the center of the hanging wall 1 into the top and bottom is defined as a saddle surface trace 9, and a region adjacent to the outside of the saddle surface track 9 is defined as a side region 10. The surface 9 is referred to as a surface because it does not serve as a surface when used. The middle fold line 17 that penetrates the center of the ridge surface trace 9 to the top and bottom is valley-folded, the fold line 18 that is the boundary line between the ridge surface trace 9 and the side area 10 is mountain-folded, and the ridge surface trace 9 is folded into an M shape. By folding the ridge surface mark 9 into an M shape, the bent walls 2 facing each other are overlapped to form an M-folded rectangular tube with the front and rear surfaces folded. The lower edge is attached and closed in the M-folded tube state, and the upper edge of the M-folded tube state includes the attaching ridge line 7 at the same time as the upper side of the bent wall 2 is attached or at an appropriate time difference. The upper region of the bent wall 2 is cut out in a substantially rectangular shape. The middle folding line 17 region of the ridge surface trace 9 is appropriately projected into a region overlapping with the bent wall 2, folded into an M shape, and the hanging hole 15 is formed by cutting out the upper portion of the bent wall 2. The rectangular cutout of the upper region of the bent wall 2 may be performed in a state where the upper side of the left bent wall 2 is a straight line. It is desirable.

  It is desirable that the folding line 18 is located on the same line as the bag folding line of the V-fold band 6 and that the side region 10 is provided with approximately the same width as the V-fold band 6. In the bag portion 3 of the rectangular tube body in which the folding line 18 is formed into a corner, the bent wall 2 is in the longitudinal direction in parallel with the joining ridge line 7, and the folding line 18 is extended so that the folding surface trace 9 and the side region 10 By forming the suspension wall 1 on the same plane, the suspension wall 1 adjacent to the bent wall 2 at a right angle becomes the longitudinal direction. By forming the suspension wall 1 as one surface, a surplus region of the trapezoidal piece 11 is generated in the lower region, and the boundary line between the trapezoidal piece 11 and the suspension wall 1 is the long bottom side 8. The long bottom side 8 may be cut along the line, or may be cut by welding. However, the long bottom side 8 is folded and the trapezoidal piece 11 is folded over the bottom wall 4 to form a trapezoidal piece 11. It is desirable to have a structure in which the periphery of the substrate is welded and fixed.

  It is desirable to form a rectangular bottom wall 4 by making a side fold line 19 that vertically extends the cutting edge line of the V-fold band 6 into a mountain fold at a right angle. However, the location of the side fold line 19 is not limited. The length ratio of the bottom wall 4 may be changed by moving the side folding line 19, and as the side folding line 19 moves in the direction of the bending wall 2, the width of the bending wall 2 becomes narrower and the bag portion 3. The height of is gradually reduced.

  FIG. 3 is a perspective view of the main part of the opened state of the handle. By pulling the upper ends of the side folding lines 19 outward and stretching the upper side of the hanging wall 1 in a straight line, the handle 5 falls down with the hem widened. Since the handle 5 has fallen outside with the hem widened, the handle 5 is folded flat and does not protrude upward from the bag portion 3. Although the knot 14 is folded inward, it may be folded outward. As shown in the figure, the handle 5 and the tie piece 14 are tilted, so there is no place protruding above the bag part 3 and there is no place to get in the way. Can be easily packed. In order to make the bag part 3 easy to stand in an open state, it is desirable that the forming material of the present invention is a slightly thick and elastic poly.

  The folding is performed from the state of FIG. 3, and the bending line 12 at the center of the bending wall 2 may be folded and folded into an M shape, but a method of folding the bending line 12 and folding it outward is desirable. A triangular side bottom region 20 is divided at the lower part of the bent wall 2 through a mountain fold line having an inverted V-shape. Both corners of the bottom side of the triangular side bottom region 20 are located at the same position as the base angle of the bent wall 2, and the apex of the bottom side of the triangular side 20 is located on the line of the bent line 12 and forms a right angle or a near right angle. It is desirable that The upper part of the bending line 12 is a mountain fold line, but the lower area of the bending line 12 with the apex of the triangular bottom area 20 as a boundary is preferably referred to as a side bottom line area 21 and is a valley fold line.

  FIG. 4 is a perspective view of the folded state. Although the tie piece 14 is shown protruding upward, it is actually desirable that the tie piece 14 bends in or out of the bag body 3 and snuggles up to the bent wall 2. By bending the upper part of the bent line 12 deeply into a bag folded state, the side bent line 19 is bent less and extends flat. The diagonal line 24 of the hypotenuse region 20 on the triangular side is deeply folded, so that the bend of the short base 16 becomes shallow, and finally the base plate 4 and the trigonal base region 20 become one general plane, It becomes a hexagon. The long bottom side 8 is deeply folded, and the bag portion 3 is folded flat. The bag part 3 folded flat is folded in two at the bottom fold line 13 at the bottom wall 4, the bag part 3 is wound around the bottom wall 4 folded in two, and folded in the same manner as tatami paper, It is fixed with a rectangle sandwiched between the other end.

  FIG. 5 is a perspective front perspective view of a principal part in a folded state. In Example 1, processing was performed based on a rectangular tube shape. In Example 2, it can be processed on the basis of a rectangular tube shape, but it is desirable to process on the basis of a flat sheet. The flat sheet is bent into a W shape to form a W-shaped folded body in which the central inverted V-shaped region is appropriately lowered. The top and bottom inverted V-shaped region at the center of the W-shaped folded body is the bottom wall 4, and both the front and rear regions are the outer wall 22.

  It is desirable that both side edges of the W-shaped folded body folded by folding the bottom fold line 13 of the bottom wall 4 are bend lines 12, and the bend lines 12 are bonded together by welding. Although the outer wall 22 may be rectangular, it may be a trapezoidal bag portion 3 having a wider upper portion, and can be easily processed by slightly inclining the bending line 12 and welding. By making the trapezoidal bag portion 3 widened in information, the upper side of the outer wall 22 can be widened, so that it becomes easy to pack, and if the size is increased, the upper side of the cash register can be covered. There is a ridge mark 9 in a region penetrating the central portion of the outer wall 22 to the top and bottom, and the ridge mark 9 is folded into an M shape to form the handle 5 and the knot 14 in the same manner as in the first embodiment. The outer wall 22 is a wide area excluding the bottom wall 4 between the bending lines 12 on both sides, and includes the hanging wall 1 including the side area 10 and the side wall 2.

  In Example 2, the lower end of the bending line 12 reaches the lower side of the outer wall 22, and a region below the ridge line fold line of the fold bottom line 13 is defined as an overlap line 23. The overlapping line 23 and the side bottom line area 21 are approximately the same size, and a fold line hanging downward from the inner end of the side bottom line area 21 is defined as a short bottom side 16. A valley fold line connecting the contact point between the overlapping line 23 and the side bottom line region 21 from the contact point between the short base 16 and the outer wall 22 is defined as an oblique line 24. With the diagonal line 24 as a boundary line, the upper region is the triangular bottom region 20, and the lower region is the overlapping surface 25. The triangular bottom area 20 and the overlapping surface 25 are substantially line symmetrical with the oblique line 24 as the center line. When the lateral bottom line area 21 is pressed from above, the oblique line 24 is folded and the triangular side bottom area 20 and The overlapping surface 25 overlaps and the bottom wall 4 spreads and becomes three-dimensional.

  FIG. 6 is a perspective view of essential parts showing the winding process. Although it is desirable to store the knot 14 in the bag portion 3, it is free to the user and may be folded and stored outside. The process of winding the bag portion 3 from the bottom with the bottom wall 4 as the core is desirable, and the number of times of winding is not limited, but it may correspond to the width of the bottom wall 4, and a structure of winding in about three folds is desirable.

  FIG. 7 is a perspective view showing a tatami paper folding process. Tatami is a traditional folding structure that is used to store Japanese clothes and Japanese clothes. After the bag part 3 is wound in three folds, about two-thirds from one end is folded back and rotated to the front to obtain the illustrated state. A region of about one third, which is the same region as the above, is inserted into the gap 26 at the other end from the same one end rotated to the front, and the folded state of the tatami paper is fixed. The surface on which the tatami paper is folded is not limited, but it is desirable to fold the handle 5 so that the handle 5 is wound inside. Since it can be folded with the same structure as tatami paper, it can be used multiple times as a returnable bag, reducing the amount of garbage compared to a single use disposable shopping bag, making it more environmentally friendly.

  Although the product of the present invention is intended for use as a shopping bag, it can also be used as a garbage bag. Moreover, after using as a shopping bag, it can also be used as a garbage bag.
