Description

  The present invention relates to boxes that can be stacked when not in use. More specifically, the present invention relates to a box that can be stacked and stored and transported because it is tapered when not in use, and can be stacked and stored and transported easily, and can be easily converted into a box having a normal corner (corner) right before use.

  Conventionally, paper boxes have a rectangular parallelepiped or cubic shape and cannot be stacked, requiring a lot of space for storage (inventory), transportation, etc. from the time the boxes are made until they are used. It was. Conventionally, as a countermeasure against this, two measures have been taken roughly. One is, for example, stored and transported in a flat state before assembly as shown in Japanese Utility Model Publication No. 6-42650, and assembled into a box immediately before use. In addition to this, many things that are assembled into a box immediately before use are currently generally used in confectionery boxes and the like. Two, for example, as shown in Japanese Utility Model Publication No. 63-74419, taper-shaped boxes are assembled, stacked, stored and transported, and added to the work just before use, with the corners at right angles. , What would be a normal box. A means for changing from a tapered box to a normal box is to hook a provided locking protrusion in the form of a primary folding piece on a side plate through a triangular secondary folding piece at the end of the side plate. Is.

  However, the second tapered and stackable box has the following problems. That is, on the inner surface of the side plate, the locking piece stands out and gives an uncomfortable appearance, and in order to create a folding space, an adhesive is applied to the glue piece at the tip of the side plate, or the side plate is bonded to the bottom plate. An extra process is required in which the inner surface and the folded plate, which is the inner surface, must be bonded together.

  The taper shape originally means a conical shape, but in the present specification, it means an inverted quadrangular frustum shape. That is, a state in which each side plate 20 (the outer plate 21 and the inner plate 22 are combined to form the side plate 20) extends from the rectangular or square base plate 10 having a parallelogram shape toward the opening (lid). Say.

  The term “use” in this specification refers to storing, transporting, selling, etc. after putting a corner into a right angle and putting a product in a box. Unused means a state in which nothing is contained in the box after the box is shaped into a taper.

  Conventionally, there is no stackable box in which the adjacent side plates 20 are provided with a connection piece 30, a connection receiving piece 40, and the like that connect each other.

  The thing of patent document 1 cuts into a required shape, and the sheet | seat which formed the fold line, the cut, and the perforation in the required position is bent and adhere | attached with a box making machine, an intermediate product is produced, and it is flat It is an assembled paper container that is stored, transported, assembled, and used immediately before use.

The thing of patent document 2 makes the box of a taper state beforehand, and is stored and transported in the state where it piled up, and presses a taper-shaped side board just before use, and makes it a normal box with a right angle. However, as described above, there are problems in terms of appearance and process.
Japanese Utility Model Publication No. 6-42650 “Assembly paper container” Japanese Utility Model Publication No. 63-74419 “Packaging Box”

  In the conventional technology, as a countermeasure against space loss during storage and transportation, there are many flat products in addition to the above-mentioned Patent Document 1 that are stored and transported and assembled into a normal box immediately before use. Yes, it's really well done, but it wasn't as easy as one-touch to assemble it into a box, and it required dexterity at the fingertips and some amount of time.

  It is reasonable to store and transport taper-shaped boxes in a stacked state, but the difference in appearance from conventional boxes is that they take the contents of goods, etc., even though the inner surface of the box. It is a problem because it stands out, and the manufacturing process is complicated.

  The problem to be solved by the present invention is to solve these problems, store and transport in a taper-shaped box, and easily form a box with a right angle immediately before use, and the appearance is a conventional assembly type. To provide something that doesn't change from a box, something that doesn't change, and that doesn't feel uncomfortable.

  The present invention is characterized in that it is tapered, stored and transported, and shaped into a box with right angles immediately before use.

  The box that can be stacked when not in use according to claim 1 is a rectangular inner plate having a rectangular outer plate 21 and fixing means described below on at least one pair of sides 12 and 12 of a rectangular or square bottom plate 10 facing each other. 22 is provided, and the fixing means includes a fixing hole 101 provided at a corresponding position between the fixing projection 221 provided at the end of the inner plate 22 and the bottom plate 10, a side plate pressing piece 23, adhesion, and the like. A rectangular single or double side plate 20 is provided on the other pair of opposite sides 11, 11. A taper forming piece 60 having a thin fan shape at one of the end portions of the adjacent side plates 20, 20. Can be bent, followed by a fan-shaped connecting piece 30 which can be bent, and a connecting receiving piece 40 which can be bent on the other side. The connecting piece 30 and the connecting receiving piece 40 are in contact with each other. Or move close together Reaches a predetermined position, the elasticity of the box material, is provided with a connecting means for causing irreversible.

  Formation refers to shaping. Shaping is shaping in the sense of shaping. The taper-shaped box is a temporary figure, and the rectangular parallelepiped box is considered to be a true figure, so that the temporary box is shaped into a true box.

  More precisely, the taper forming piece 60 should be called a tapered state forming piece, and is for forming a tapered box. A thin fan shape means a fan shape with a small depression angle. Even if it is not a fan shape, it may be a triangle with the same depression angle. Since the depression angle is small, it does not matter whether it is a circular arc or a straight line. This depression angle determines how the taper is opened. The reason why the folding is provided is that when the box is tapered and the corner is shaped at a right angle, the boundary needs to be changed from a bent state to a straight state. Besides that, in order to make a box from flat paper, it has to be bent in various ways. Note that all the portions indicated by dotted lines in the development of the drawing can be bent.

  The reason why the connecting piece 30 is fan-shaped is that the side plate 20 connected through the taper forming piece 60 can be rotated left and right with one side of the bottom plate 10 as a rotation axis. This is because the connecting piece 30 is sandwiched between the outer plate 21 and the inner plate 22. Other shapes may be used as long as the sector having the radius of the height of the side plate 20 has the maximum size and is smaller than this. Since the connection receiving piece 40 is used in a state of being folded on the side plate 20, there is no need for a sector shape.

  The reason why the double side plates 20 are required on at least one pair of sides is that the connection piece 30 and the connection receiving piece 40 need to be sandwiched between the outer plate 21 and the inner plate 22 in a state where they overlap or approach each other. is there. When the auxiliary piece 50 is provided, the auxiliary piece 50 needs to be sandwiched between the two side plates. There is also a meaning of hiding the connecting piece 30 and the like from the outside. The reason why a fixing means is required for the inner plate 22 is to keep the connecting piece 30 and the like in between. The other pair of sides may be single.

  The fixing means for the inner plate 22 normally uses the side plate pressing edge 23. When the side plate pressing edge 23 is provided outside the inner plate 22 sandwiching the connecting piece 30 and the connecting receiving piece 40 and assembled into a tapered box, the side plate pressing piece 23 is provided below the side plate pressing pieces 23 provided on the inner plate 22 on both sides. Mogu Alternatively, the sawtooth protrusions 231 and the small protrusions 232 are provided on both sides of the side plate pressing piece 23, and the fixing holes 201 are opened at the corresponding positions of the adjacent inner plates 22, and these protrusions are fitted and fixed. This will be described in Examples below. Alternatively, a fixing projection 221 is provided on the outer side of the inner plate 22, a fixing hole 101 is opened at a position corresponding to the fixing projection 221 on the side of the bottom plate 10 where the inner plate 22 is provided, and the fixing projection 221 is fitted and fixed. Or you may fix with an adhesive agent. In the case of using an adhesive, the inner plate 22 may be directly fixed to the outer plate 21 without using the side plate pressing piece 23. You may fix the side plate pressing piece 23 with an adhesive agent.

  The connection means that when the connection piece 30 and the connection receiving piece 40 are in contact with each other or close to each other and the position is changed and reaches a predetermined position, it cannot be restored due to the elasticity of the box material. Changing the position is called moving. In the present invention, reaching the predetermined position means that the tapered side plate 20 is pushed and becomes a right angle.

  The connecting piece 30 and the connecting receiving piece 40 are assembled into a tapered box in a state where they are sandwiched between the outer plate 21 and the inner plate 22 in a state of being overlapped or approaching each other. Normally, they are in contact with each other, but in the contact between the cut surfaces of Example 3 or the like, there may be cases where they are not in contact with each other, but they are close to each other. When the auxiliary piece 50 and the connection receiving piece 40 are connected, the connection piece 30 is sandwiched between them, and such a state is also referred to as an approached state. During the movement, they are in contact with or close to each other. Depending on the relationship between the connecting piece 30 and the connecting receiving piece 40, the hooking piece 33 and the fitting hole 43 may be provided on either side. For ease of explanation, the connecting piece 30 and the connecting receiving piece 40 are named differently, but their functions are the same.

  As for the connecting means, a hooking piece 33, a notch 51 or the like is provided on one of the connecting piece 30 or the auxiliary piece 50 and the connecting receiving piece 40, and a hooking part such as the oblique side 41 or the fitting hole 43 is provided on the other. It is established by providing. On the other hand, for example, when the connecting piece 30 or the auxiliary piece 50 is moved and the predetermined position, that is, the hooking piece 33 or the like is hooked on the hypotenuse 41 or the fitting hole 43, the connecting piece 30 and the auxiliary piece 50 are connected in the reverse direction.

  As the material of the box, cardboard used for a normal paper box material is mainly used, but it may be a thin cardboard or a thin sheet of plastic. In addition, any sheet-like material forming the box may be used.

  The lid is made in the same way outside the box body. The lid may be a box that is slightly larger in size, that is, the bottom plate of the box body is set to fit inside the lid, just so that it has a low height. Even if the height is low, stacking is possible as long as it spreads in a tapered shape.

  The box that can be stacked when not in use is the end of the side plate 20 of the double side plate 20 that is not provided with a bendable taper-formed piece 60 and a fan-shaped connecting piece 30 that can be bent. The auxiliary piece 50 with or without one of the connecting means is provided so as to be bendable.

  The unused stackable box according to claim 2 is obtained by adding an auxiliary piece 50 to that of claim 1.

  The double side plate 20 is a side plate 20 composed of an outer plate 21 and an inner plate 22. Of the outer plate 21 and the inner plate 22, the taper forming piece 60 and the connecting piece 30 are not provided at the end portion so that they can be bent, that is, at the end portion of the side plate 20 where the end portion is vacant. The non-useable stacking box according to claim 1, wherein 50 is provided so as to be bent.

  A part of the connecting means may or may not be provided on the auxiliary piece 50. The auxiliary piece 50 may be provided adjacent (continuously provided) so that the taper forming piece 60 having a thin fan shape can be bent. The shape of the auxiliary piece 50 is not limited to a sector shape. This will be described later with reference to FIG.

  The box that can be stacked when not in use according to claim 3 is formed on the surface or the cut surface of the connecting piece 30 or the auxiliary piece 50 or the connecting receiving piece 40 when the box is tapered and when the box has a right angle. Depending on the taper holding means or the outer plate 21 and the inner plate 22 provided with the notches 31, 51 or the hook piece 33 or the periphery 41, the receiving concave portion 42, the fitting hole 43 or the tapered concave portion 44. Sometimes, the boundary line between the taper holding means 50 or the taper forming piece 60 formed by the auxiliary piece 50 provided with the taper holding part 54 in contact with the boundary line between the outer plate 21 and the inner plate 22 and the taper formation with the boundary line. A perpendicular line is drawn from the intersection 61 with the arc of the piece 60, and the line segment to the intersection 38 with the extension line of the adjacent inner plate 21, and the boundary line with the line segment of the extension line and the oblique side 41 of the adjacent connection receiving piece 40. Te of the shape surrounded by Provided a tapered holding means consisting of Par holding unit 34 is according to claim 1 or 2.

  The box that can be stacked when not in use according to claim 3 is obtained by adding a taper holding means to that of claim 1 or 2. In the first or second aspect, when the opening force is applied to the tapered side plate 20, the side plate 20 may open. In order to prevent this, a taper holding means is added.

  The first of the taper holding means is that when the inner plate 22 is bent and overlapped with the outer plate 21, the auxiliary piece 50 overlaps the connecting piece 30, so that the surface of the connecting piece 30 or the auxiliary piece 50 or the connecting receiving piece 40 or The cut surface is provided with notches 31, hooks 33 or notches 51, receiving recesses 42, fitting holes 43 or tapered recesses 44 depending on when the box is tapered and when the box corners are at right angles. is there. Since the hooking piece 33 is hooked on the taper recess 44 in the taper shape, the side plate 20 is not opened. When the side plate 20 is pressed and the angle becomes a right angle, the hanging piece 33 is hooked on the hypotenuse 41 and the receiving recess 42 and shaped into a rectangular parallelepiped box. In addition, the periphery 41 means the outer peripheral part of the connection receiving piece 40, and the hypotenuse 41 is the one part. Since the connection receiving piece 40 is not limited to a triangle, the connection receiving piece 40 becomes the periphery 41 when the peripheral portion is hooked on the hanging piece 33 or the like in another shape.

  The second of the taper holding means is the auxiliary piece 50. When the taper holding means is sandwiched between the outer plate 21 and the inner plate 22, the taper holding portion 54 in contact with the boundary line between the outer plate 21 and the inner plate 22 is provided. The auxiliary piece 50 is provided. When the upper edge portion 24 is present, the upper edge portion 24 is in contact with the boundary line between the outer plate 21 and the inner plate 22.

  The third one of the taper holding means draws a perpendicular line from the boundary line with the taper forming piece 60 and the intersection 61 between the boundary line and the arc and extends to the intersection 38 with the extension line of the adjacent inner plate 21. In addition, this is due to the taper holding piece 34 having a shape surrounded by the extended line and the boundary line with the oblique side 41 of the adjacent connection receiving piece 40.

  By providing these taper holding means in addition to the unused stackable box according to claim 1 or 2, the side plate 20 does not move in the direction of opening outward from the tapered state, but is closed. It moves in the direction where the corners are perpendicular. Therefore, even if the taper-shaped boxes are stacked and a force for opening the side plate 20 is applied, the side plate 20 is not opened and the tapered state is stabilized.

  The box which can be stacked when not in use according to a fourth aspect is the one according to any one of the first to third aspects, wherein the coupling means is provided on the surface of the coupling piece 30 or the coupling receiving piece 40. This is due to the connection between the surfaces. For example, this is due to the hanging piece 33, the receiving recess 42, the fitting hole 43, etc. provided on the surface.

  The box which can be stacked when not in use according to a fifth aspect is the one according to any one of the first to third aspects, wherein the connecting means is provided on the cut surface of the connecting piece 30 or the connecting receiving piece 40. This is due to the connection between the cut surfaces. For example, this is due to the hanging piece 33, the receiving recess 42, or the like provided on the cut surface. In the seventh embodiment, an example of cut surfaces is described.

  The box that can be stacked when not in use according to claim 6 uses the elasticity of the box material in which the connecting means works in the vertical direction with respect to the surface of the connecting piece 30 or the connecting receiving piece 40. It is a thing of any one of -3. For example, those described in Examples 1 and 2.

  The box that can be stacked when not in use according to claim 7 uses the elasticity of the box material in which the connecting means works in parallel with the surface of the connecting piece 30 or the connecting receiving piece 40. It is a thing of any one of -3. Example 3 is described with an example.

In addition to the effect that there is no or not so much, the bottom plate 10 is a parallelogram, so that there is an effect that a rhomboid parallelogram box can be formed.

  The purpose of saving space when storing and transporting boxes was achieved by assembling, storing and transporting tapered boxes, and making them right-angled boxes just before use. Hereinafter, the best mode for carrying out the invention will be described by way of examples.

  A stackable box according to the first embodiment will be described with reference to FIG. FIG. 1A is a developed view of stackable boxes. A rectangular outer plate 21 is provided on each side of the rectangular bottom plate 10, a rectangular inner plate 22 is provided at the tip, and a long side plate pressing piece 23 is provided at the tip. In order to make the explanation of the figure easy to understand, a is attached to the side plate provided on the long side 11 and b is attached to the side plate provided on the short side 12. A dotted line in the figure indicates a bent portion (location), which is easily bent. All the dotted lines in the figure can be bent. The place to be written is omitted so that it can be bent.

  Thin fan-shaped taper forming pieces 60 are provided at both ends of the outer side plate 21a provided on the long side 11 (to be precise, the taper forming pieces 60 should be provided so that they can be bent). A connecting piece 30 is provided. A cut 31 is made in the connecting piece 30. As shown in FIGS. Thin fan-shaped taper forming pieces 60 having opposite directions are provided at both ends of the inner plate 22a, and fan-shaped auxiliary pieces 50 having opposite directions are provided at the ends thereof. The fan shape of the auxiliary piece 50 and the fan shape of the connecting piece 30 are not the same shape. The auxiliary piece 50 has a larger depression angle. The two taper forming pieces 60 have the same shape when turned over. When the inner plate 22a is bent and overlapped with the outer plate 21a, the two taper forming pieces 60 are overlapped, and the thin fan shape has the same depression angle. This depression angle determines how the tapered box opens.

  The sector of the taper forming piece 60, the connecting piece 30, and the auxiliary piece 50 is for the outer plate 21a and the inner plate 22a to be overlapped so that the long side 11 can be rotated (moved) easily. It does not have to be strictly a sector, and may be slightly deformed or polygonal. If the sector having the radius of the height of the side plate 20 is the largest shape and smaller than this, the side plate 20 moves.

  At both ends of the outer plate 21b provided on the short side 12, connection receiving pieces 40 of a right triangle (hereinafter simply referred to as a triangle) are provided. The right triangle does not have to be exact, and the right angle portion may be slightly acute. Nothing is provided at both ends of the inner plate 22b.

  In the fan-shaped connecting piece 30, the cut 31 shown in FIG. (A) is changed to a hanging piece 33 as shown in FIGS. (B), (C), and (D). The hooking piece 33 is a triangular pyramid-shaped protrusion, and is hooked on the hypotenuse 41 of the connection receiving piece 40 when the tapered box is shaped into a box with a right angle (rectangular box). The position may be anywhere on the radius, but the box becomes stronger near the arc. The angle of the radius at which the tip of the hanging piece 33 is located is such that when the box is assembled into a taper shape, transported and stored, and the corner is shaped at right angles just before use, that is, when the box is shaped into a rectangular parallelepiped box, It is set so that it is exactly on the hypotenuse 41. To make it, a short notch 31 is put on the radius, and the center of the notch 31 is pressed on a base with a triangular pyramid depression. In (C) and (D) of the figure, for the sake of clarity, it is turned upside down.

  The auxiliary piece 50 is provided with a cut 51 in the arc portion. The length of the notch 51 may be appropriate. The outer side (opposite side of the bottom plate 10) of the notch 51 is slightly bent upward. (To make it easier to catch. When the inner plate 22a is folded and overlapped, it is bent downward.) The hooking piece 33 is hooked on the hypotenuse 41 of the connection receiving piece 40, and the reliability is doubled. It is. “Upward” refers to a direction from the bottom of the box toward the lid (opening) in the state of the development. The connecting piece 30 may be similarly formed by making a cut 31 in the arc portion. Example 9 described later is as described above.

  The connecting piece 30 and the connecting receiving piece 40 may be adjacent to each other, regardless of whether they are attached to the outer plate 21a provided on the long side 11 or the outer plate 21b provided on the short side 12. It may be attached to. That is, the connection receiving piece 40 may be attached to the outer side plate 21a contrary to (A).

  The connection receiving piece 40 is simple and effective to form a triangle, but may have other shapes. As will be described later (another embodiment), since there are recesses, holes, and the like outside the hypotenuse 41, the shape is not selected.

  In order to assemble the taper-shaped box, as shown in (E) of the figure, the outer plate 21a and the inner plate 22a provided on the long side 11 are folded and overlapped so as to be folded, and the bottom plate 10 is more than a right angle. Bend outwards slightly diagonally. Similarly, the outer side plate 21a and the inner side plate 22a provided on the opposite side 11 are also bent slightly diagonally outside the right angle. The cross-section becomes like a trapezoid. Both side plate pressing pieces 23a overlap the bottom plate 10.

  Since the two taper forming pieces 60 provided at both ends of the side plates 21a and 22a overlap each other, they are bent. Further, since the connecting piece 30 and the auxiliary piece 50 are overlapped, the two pieces are bent along the taper forming piece 60.

  Next, both of the triangular connection receiving pieces 40 at both ends of the outer plate 21b provided on one short side 12 are bent along the dotted line so as to overlap inside, and the two outer plates 21b are overlapped. The fan-shaped connecting piece 30 and the fan-shaped auxiliary piece 50 are folded so as to overlap. Next, the inner plate 22b is bent inward, and the side plate pressing pieces 23b are overlapped with the bottom plate 10. The connecting piece 30 and the auxiliary piece 50 are sandwiched between the outer plate 21b and the inner plate 22b. The side plate pressing piece 23b of the short side 12 is put on the side plate pressing piece 23a along the left and right long sides 11. The side plate pressing pieces 23b of the short side 12 are also moved to the lower side of the side plate pressing pieces 23a, 23a of the long side 11 and fixed.

  Next, the outer plate 21b, the inner plate 22b, and the side plate pressing piece 23b provided on the other short side 12 are similarly set. A tapered box, ie, an inverted quadrangular truncated pyramid shaped box is created. This is an unused stackable box. An appropriate number of stackable boxes in this state are stacked and stored and transported.

  Immediately before use, this taper-like stackable box is placed in a state where one outer side plate 21 is placed on a stand as shown in FIG. When both ends of 21 are pressed (as indicated by the arrows in the figure), the corners become right-angled as shown in the figure (G) with one touch, resulting in a rectangular parallelepiped box. The taper forming piece 60 is inserted between the outer plate 21b and the inner plate 22b provided on the short side 12, and the hook piece 33 provided on the fan-shaped connecting piece 30 and the notch 51 of the auxiliary piece 50 are connected in a triangular shape. It hangs on the hypotenuse 41 of the piece 40 and does not return to the tapered box. Since the hanging piece 33 and the notch 51 that hang on the connection receiving piece 40 are doubled, the reliability is increased. The appearance is exactly the same as a prior art assembly box.

  A stackable box of Example 2 will be described with reference to FIG. In Example 2, the bottom surface is square, the side plate is thick, and further provided with a taper state holding function.

  FIG. 2A is a development view of the stackable boxes of the second embodiment. An outer plate 21 is provided on each side 11 and 12 of the square bottom plate 10 toward the outer side, an upper edge 24 is provided at the tip, an inner plate 22 is provided at the tip, and a side plate pressing piece 23 is provided at the tip. Is provided. For easy understanding of the drawing, a is attached to the side plates provided on the two sides 11 and 11 facing each other, and b is attached to the side plates provided on the other two sides 12 and 12 facing each other.

  A thin fan-shaped taper forming piece 60 is provided at one end of the outer plate 21a provided on the two sides 11 and 11 facing each other, and a connecting piece 30 described later is further provided. Similar to the first embodiment, a taper forming piece 60 and a fan-shaped connecting piece 30 are provided at the other end of the outer plate 21a. A taper forming piece 60 is provided at one end of the inner plate 22a, and an elongated triangular auxiliary piece 50 is provided. From the intersection 61 of the boundary line with the taper forming piece 60 and the arc, a perpendicular line is drawn with respect to this boundary line, and the taper holding portion 54 extends to the intersection of the boundary line between the inner side plate 21a and the side plate pressing piece 23a. And The function of the taper holding portion 54 will be described later. The auxiliary piece 50 is not provided at the other end of the inner plate 22a. The auxiliary piece is not always necessary. It is not necessary.

  As shown in (B), the connecting piece 30 on the one end side has a boundary line (dotted line portion) with the taper forming piece 60 and an intersection 61 between the boundary line and the arc from the boundary line, that is, the sector-shaped radius. The vertical line is drawn, the line segment to the intersection 38 with the extended line of the boundary line between the outer plate 21b and the upper edge 24b, the extended line between the outer plate 21b and the upper edge 24b, and the oblique side 41 of the connecting piece 40 It is a quadrangular shape surrounded by the boundary line. It is larger than the fan-shaped connecting piece 30 of the first embodiment. A line segment between the intersection 61 and the intersection 38 is the taper holding portion 34. However, to be exact, it is only necessary to have a few line segments near the intersection point 38 instead of the entire line segment between the intersection point 61 and the intersection point 38. That is, other line segments may be curved.

  When assembled into a tapered box, the connecting piece 30 is sandwiched between the outer plate 21b and the inner plate 22b, and the taper holding portion 34 is composed of the outer plate 21b and the upper edge portion 24b, and the upper edge portion 24b and the inner plate. It touches the boundary line with 22b. Therefore, the taper holding portion 34 does not advance upward, does not move in the direction in which the outer plate 21a and the inner plate 22a open, and the tapered state is held. That is, the rotational movement to the outside of the side plates 21a and 22a is prevented. The outer plate 21a and the inner plate 22a can move in the closing direction. Therefore, the connecting piece 30 also serves as the taper holding portion 34. The taper holding part 34 may have other functions as long as it has this function. The taper holding part 34 should be called a taper state holding part.

  As in the first embodiment, the connecting piece 30 is provided with a hooking piece 33 that is hooked and connected to the hypotenuse 41 of the connecting receiving piece 40 when the corner of the box is shaped at a right angle.

  As shown in (C), in the sector-shaped connecting piece 30 on the other end side, a cut 31 is made in the arc portion and bent downward to be changed into a taper holding portion 34 and a hook piece 33. In the figure, the top and bottom are reversed for easy understanding. In addition, the inside of the circle at the tip of the arrow in FIG. The position of the notch 31 is such that when the taper holding portion 34 is assembled into a tapered shape, the taper is hooked on the hypotenuse 41 to maintain the taper state, and when the hooking piece 33 is shaped with a right angle, the hypotenuse 41 is set so that the shape of the box is stable.

  Triangular connection receiving pieces 40 are provided at both ends of the outer plate 21b provided on the other two sides 12 and 12 facing each other. Nothing is provided at both ends of the inner plate 22b.

  The reason why the auxiliary piece 50 is not provided on the other end side of the inner plate 22a is to incorporate a plurality of examples in one embodiment, both of which have the auxiliary side 50, and both may have no auxiliary side 50. . It is the same purpose that the connecting piece 30 is changed between one end and the other end of the outer plate 21a.

  The assembly to the box and the method of use are the same as those in the first embodiment. Since there is an upper edge portion 24 between the outer plate 21 and the inner plate 22, a thick side plate can be obtained. Since the elongated triangular auxiliary pieces 50 are long, they are overlapped when the tips hit each other. The auxiliary piece 50 is sandwiched between the outer side plate 21b and the inner side plate 22b, and in addition to the effect of reinforcing the side plate, when the box is assembled in a tapered state, the perpendicular 54 to the boundary line with the taper forming piece 60 is upward. There is also an effect of acting as a taper holding function that prevents the side plate 20 from opening outward.

  The stackable box of the second embodiment has a thick side plate, and because of the taper holding portions 34 and 54, the taper state is reliably maintained even when a large number of the side plates are stacked and a load is applied when not in use. There is.

  A stackable box of Example 3 will be described with reference to FIG. In the stackable box of the third embodiment, a pair of side plates 20a provided on the long side 11 of the rectangular bottom plate 10 is single, and a pair of side plates provided on the short side 12 (an outer plate 21b and an inner plate 22b). It is a doubled one. The connecting means is provided on the cut surface. Also in Example 3, in order to make the explanation of the drawing easy to understand, a is attached to the side plate provided on the long side 11, and b is attached to the side plate provided on the short side 12.

  FIG. 3A is a developed view of stackable boxes. A rectangular side plate 20 a is provided on the long side 11 of the rectangular bottom plate 10 toward the outside. At one end of the side plate 20a, a thin sector-shaped taper forming piece 60 is provided, and further, the following connecting piece 30 obtained by deforming the sector shape is provided. A thin fan-shaped taper forming piece 60 is provided on the other end side of the side plate 20a, and a fan-shaped connecting piece 30 is provided in the same manner as that shown in FIG. Four cuts 31 are made in the arc portion, bent downward, and changed into a taper holding portion 34 and a hook piece 33.

  As shown in FIG. 3B, the shape of the connecting piece 30 on one end side is formed by cutting the upper part (in the drawing) of the fan-shaped connecting piece 30 of the first embodiment in parallel with the short side 12 and hanging the hook 33 on the arc portion. Is provided. In addition, the thing of the sickle shape above the connection piece 30 is the connection receiving piece 40. As shown in (C), the connection receiving piece 40 is bent on the outer plate 21b and is connected to the connection piece 30 in a state of being overlapped with the outer plate 21b.

  The sickle-like connection receiving pieces 40 are provided at both ends of the outer plate 21b. As described above, the connecting piece 30 and the connecting receiving piece 40 have a relational shape obtained by cutting each other from one square, and the positions of the receiving recess 42 and the tapered recess 44 are determined by a trial and error method.

  An outer side plate 21b, an inner side plate 22b, and a side plate pressing piece 23b are provided on one short side 12 toward the outside. Saw-tooth projections 231 or small projections 232 are provided on both sides of the side plate pressing piece 23b.

  Fixing holes 201 into which these protrusions 231 and 232 are fitted are provided at locations corresponding to these along the long side 11 of the side plate 20a.

  On the other short side 12 (left side in the figure), only the outer plate 21b and the inner speed plate 22b are provided, and the side plate pressing piece 23b is not provided. On the outside of the inner plate 22b, normally two rectangular fixed protrusions 221 having a width (protrusion allowance) of about the thickness of the bottom plate 10 and an appropriate length are provided. If the side plate 20b is long, it may be increased as appropriate.

  A fixing hole 101 having a size in which the fixing protrusion 221 fits is provided at a position along the short side 12 of the bottom plate 10 corresponding to the fixing protrusion 221. These are fixing means for the inner plate 22b, and even if the fixing hole 101 is provided at the end of the bottom plate 10, in the normal usage method of the box, the presence of the fixing hole 101 is not noticeable because of the bottom surface of the box. .

  In addition to this, the fixing means may be fixed with an adhesive. The reason that the side plate pressing piece 23 is not provided on the other end side is to incorporate a plurality of examples in one embodiment, both of which have the side plate pressing piece 23 and both of which may have no side plate pressing piece 23.

  When the box is assembled in a tapered state, the position is set so that the hook piece 33 of the connection knitting 30 on one end side fits into the taper recess 44 of the connection receiving piece 40. Serves as a taper holding function. When the tapered box is shaped to have a right angle, the position of the receiving recess 42 is determined so that the hook 33 fits into the receiving recess 42. In addition, when the test was performed with a prototype, this was performed successfully. However, when the thickness of the paper is large, the hanging piece 33 is hooked, etc., and it does not go smoothly, as shown in (D) In addition, a cut portion 35 may be provided, and the hanging piece 33 may be provided with a cushion (elasticity). The width of the cut portion 35 may be about the height of the hanging piece 33. Although omitted in the drawing because it is small and difficult to draw, the orientation of the hanging piece 33 and the tapered recess 44 is not accurate. Since the hanging piece 33 and the receiving recess 42 are not shared, the shape must be determined for the hanging piece 33 and the receiving recess 42, respectively.

  If the hanging piece 33 and the receiving recess 42 do not fit well, such as when the thickness of the paper is small, as shown in (E), the size of the hanging piece 33 is doubled. Alternatively, it may be bent at the dotted line portion to make it easier to hang. The receiving recess 42 may be formed into an L-shaped cut 45 and bent to make it easy to hook.

  To assemble into a tapered box, it is the same as in Example 1. Although the shape of the connection receiving piece 40 has also changed, it is bent in the same manner and overlapped with the outer plate 21b. The fixing means for the inner side plate 22b is also appropriately selected. A tapered box is created. In the third embodiment, since the side plate 20 is single, the material can be saved. It is also a feature that the connecting means works between the cut surfaces. The fan-shaped connecting piece 30 on the other end side is the same as that shown in FIG.

  A stackable box of Example 4 will be described with reference to FIG. The fourth embodiment indicates that the connecting piece 30 and the connecting receiving piece 40 may be provided on the inner plate 22 instead of being provided on the outer plate 21 as in the first to third embodiments. Also, another example of the connecting means will be described. The drawings are partial development views, all showing the connecting piece 30 and the connecting receiving piece 40, etc., and the overall view is omitted.

  A part (A1) is a partial development view, and fan-shaped connecting pieces 30 are provided on both ends of the inner plate 22a provided on the long side 11 via taper forming pieces 60. Triangular connection receiving pieces 40 are provided on both ends of the inner plate 22b provided on the short side 12 with the right-angled part facing down (in the drawing). As shown in (A2), the connecting piece 30 and the connecting receiving piece 40 have shapes similar to those of the first to third embodiments when the inner plate 22a is bent and overlapped with the outer plate 21a. Furthermore, as shown to (A3), when the inner side board 22b is bent, it becomes the same as that of Examples 1-3.

  As shown in (A1), an L-shaped cut 31 is made in the connecting piece 30 and pushed upward (becomes downward when the inner plate 22a is bent) to form a hanging piece 33. The position is determined by a trial and error method so that the tapered box is placed on the hypotenuse 41 of the connection receiving piece 40 when the tapered box is shaped into a box having a right angle immediately before use. To assemble into a tapered box, it is the same as in Example 1. The usage method and the like are the same as in the first embodiment. In this state, there is no taper holding function. As shown in FIG. 2C of Example 2, when four cuts 31 are put in the arc portion of the fan-shaped connecting piece 30 and bent upward, the taper holding portion 34 and the hook piece 33 are changed. Has a taper holding function.

  In (B), right-sided triangular auxiliary pieces 50, 50 are provided at both ends of each of the outer plates 21a, 21b of (A1). When the auxiliary pieces 50 and 50, the connecting piece 30, and the connecting receiving piece 40 are also bent in the same manner as in (A1) to (A3), the results are as in the first to third embodiments. By providing the auxiliary pieces 50, 50, there is an effect that the side plate is firmly secured after shaping into a box. Others are the same as (A1). In addition, it is the same as that shown to (A1)-(A3) that there is no holding function in (B). In order to have a taper holding function, it may be the same as (A1) to (A3).

  In (C1), the connection receiving piece 40 of (A1) is changed to a square and transferred to both ends of the outer plate 21b. A fitting hole 43 is opened in the connection receiving piece 40. The hanging piece 33 of the connecting piece 30 remains as it is. (C1) shows the stage of cutting. As shown in (C2), the connection receiving piece 40 is bent toward the outer side plate 21b, and the inner side plate 22a is bent toward the outer side plate 21a. The usage method and the like are the same as in the first embodiment. If (C1) and (C2) are left as they are, there is no taper holding function, and in order to have a holding function, it may be the same as shown in (A1) to (A3) and (B).

  In (D), fan-shaped auxiliary pieces 50, 50 are provided on both inner side plates 22a, 22b. The connecting piece 30 and the connecting receiving piece 40 are provided on both sides of the outer plates 21a and 21b. Since there are two auxiliary pieces 50, there is an effect that the side plate is firmly fixed after shaping into a box. Of the two auxiliary pieces 50, 50, the taper forming piece 60 is provided adjacent to the auxiliary piece 50 provided on the inner plate 22 a adjacent to the outer plate 21 a provided with the connecting piece 30. In the case of (D) as it is, in order to have no taper holding function and to have a holding function, it is sufficient to perform the same as (A1) to (A3). Note that the shape of the auxiliary piece 50 provided on the inner plate 22b, that is, the direction without the taper forming piece 60 is not limited to a fan shape, and may be another shape such as a square or a rectangle.

  If the notch 31 and the hanging piece 33 are appropriately provided in the arc portion or the plane portion of the connecting piece 30, a taper holding function can be provided as in the second to third embodiments.

  A stackable box of Example 5 will be described with reference to FIG. Example 5 relates to a taper holding means. Although the taper holding means has been partially described in the second embodiment, other parts will be described.

  What is shown in (A) is the same as that shown in (C) of FIG. In the taper state, the taper holding portion 34 is hooked on the oblique side 41 of the connection receiving piece 40 and does not move in the direction in which the outer side plate 21a and the inner side plate 22a are opened, so that the box maintains the taper state. When the corner becomes a right angle, the hanging piece 33 hangs on the hypotenuse 41 and becomes a normal box shape.

  (B) is explanatory drawing of (A), and the connection piece 30 advances in the arrow direction of (circle) mark, but cannot advance in the arrow direction of * mark. That is, since the outer side plate 21a and the inner side plate 22a cannot move in the opening direction from the tapered state, the tapered state is stabilized. Since the outer plate 21a and the inner plate 22a can move in the closing direction, a box having a right angle can be formed. The elasticity in this case acts in the paper cutting direction, that is, in the direction perpendicular to the paper surface.

  (C) is an explanatory view of the connecting means (mechanism) between the cut surfaces. Because of the cut portion 35 provided in the peripheral portion of the connecting piece 30, the support base 32 protruding in a peninsular shape is caused by the elasticity of the box material. Move. A hook 33 is provided at the tip of the support base 32. On the other hand, a tapered recess 44 and a receiving recess 42 are provided in the curved portion of the connection receiving piece 40. As indicated by arrows and ◯ × in the figure, the peninsula-shaped support base 32 is lowered by elasticity (the peninsula is bent) and advances from a tapered shape to a rectangular parallelepiped shape, that is, from right to left in the figure. Although the hanging piece 33 advances, in the opposite direction, the hanging piece 33 pushed up by elasticity is caught on the triangular concave portions 42 and 44 and cannot move. Even when the rectangular parallelepiped shape is formed, the hanging piece 33 does not advance rightward from the triangular receiving recess 42, so that the rectangular parallelepiped box is stable. The elasticity in this case works in a direction parallel to the paper surface.

  (D) shows the taper holding portion 34 other than that shown in the second embodiment (FIG. 2), and the shape is similar (however, the shape in which the connection receiving pieces 40 minutes are combined in an inverted shape) is provided. The location is different. The taper holding part 34 is a part of the connecting piece 30. A taper forming piece 60 is provided at the end of the inner plate 22a, and a taper holding part 34 attached to the connecting piece 30 is provided at the end thereof. When the inner plate 22a is bent and overlapped with the outer plate 21a, it is similar to that shown in the second embodiment (FIG. 2). (There is no upper edge 24.)

  (E) shows a taper forming piece 60 and a connecting piece 30 provided at the end of the outer plate 21a shown in (D). The connecting piece 30 also serves as the taper holding part 34. The connecting piece 30 shown in (D) is changed to an auxiliary piece 50 having the same shape. When superimposed on the inner plate 22a, it becomes the same as that shown in (D). Further, the auxiliary piece 50 has a perpendicular line 54 to the boundary line with the adjacent taper forming piece 60, and this part is in contact with the boundary line between the outer side plate 21 b and the inner side plate 22 b and functions as the taper holding portion 54. To do.

  As described above, the taper holding portions 34 and 54 are like a kind of check piece (valve) that does not advance in the direction in which the side plate 20a opens from the tapered state but advances in a direction perpendicular to the side plate 20a.

  A stackable box according to the sixth embodiment will be described with reference to FIG. Example 6 relates to a means for connecting the surfaces.

  (A) is obtained by making two cuts 31, 31 in the peripheral part of the connecting piece 30 and bending it downward to form a hanging piece 33. In the figure, it is turned upside down for easy understanding.

  (B) is obtained by putting a U-shaped cut 31 into the connecting piece 30 and bending it downward to form a hanging piece 33. In the figure, it is turned upside down.

  (C) is an L-shaped cut 31 which is bent 90 degrees downward to form a hanging piece 33, which is also turned upside down.

  (D) shows a V-shaped hanging piece 33 (as a hanging piece 33) by placing a short straight cut 31 and pushing the center of the cut 31 downward on a table provided with a triangular pyramid-shaped depression. (Inverted V-shaped, that is, mountain-shaped) is also turned upside down in the figure.

  (E) inserts a straight short cut 31 and pushes it in a shape that cuts the cone vertically, on a table with a concavity that cuts the cone vertically. This is a hanging piece 33 that is cut into two pieces. This is also upside down in the figure.

  (F) is the one in which a cut 31 is made in the peripheral portion and one side is bent downward to form a hanging piece 33, which is also turned upside down in the figure.

  (G) is a connection receiving piece 40 provided with a fitting hole 43 for connection.

  (H) shows a state in which the hanging piece 33 provided on the connecting piece 30, in this example, the mountain-shaped hanging piece 33 and the connecting receiving piece 40, in this example, the hypotenuse 41 is connected.

  A stackable box of Example 7 will be described with reference to FIG. Example 7 relates to a means for connecting cut surfaces.

A hook 33 and a receiving recess 42 are provided at the tip of the peninsula-shaped support 32 and 47.

  (B) cuts the hanging piece 33 of the connecting piece 30 into about twice the size, and folds the center dotted line part in half to ensure the catch.

  (C) is obtained by correcting the cut shape of (B) and folding it in half to make the same shape.

  In (D), in order to secure the receiving recess 42 of the connection receiving piece 40, a notch 45 is diagonally cut and the dotted line portion is bent.

  (E) is cut into a triangular concave portion and a protruding convex portion 46, and is bent into a receiving concave portion 42 to ensure catching.

  (F) is obtained by inserting an L-shaped cut 45 and bending the dotted line portion into a receiving recess 42.

  (G) The shape of the connecting piece 30 is cut from the tip of the arrow, and when pressed, the width is reduced by elasticity, and the mushroom-shaped column corresponding to the connecting receiving piece 40 is formed. The part has a deformed shape. When the connecting piece 30 is pressed as indicated by an arrow, the hook piece 33 at the tip end portion becomes narrow, enters into the receiving recess 42 of the connecting receiving piece 40, spreads out, and is connected.

  A stackable box of Example 8 will be described with reference to FIG. Example 8 relates to a connecting means by elasticity in the torsional direction.

  (A) shows the front-end | tip part of the L-shaped connection piece 30. FIG. The hanging piece 33 protruding vertically in the longitudinal direction is bent slightly downward as shown by an arrow and is hooked. The figure is before brazing.

The connection receiving piece 40 is provided with a fitting hole 43. When the connecting piece 30 advances in the longitudinal direction toward the hanging piece 33 at the tip, the hanging piece 33 is engaged with the fitting hole 43 because a downward force is applied due to the elasticity of the box material (material). In the opposite direction, it cannot move. That is, they are connected. This means that torsional elasticity is used.

  A stackable box according to the ninth embodiment will be described with reference to FIG. FIG. 9 is a development view of the stackable boxes of the ninth embodiment. In the ninth embodiment, the bottom plate 10 has a parallelogram shape. Except that the bottom plate 10 is a parallelogram, the first embodiment is simplified and the auxiliary piece 50 is excluded. The connecting means is a cut 31 instead of the hanging piece 33. The method of assembling the box in a tapered shape and the like are the same as in the first embodiment. A taper holder may be attached to the fan-shaped connecting piece 30.

  As a special note, it is necessary to increase the angle at which the corners of the side plate pressing pieces 23 are dropped at locations where the apex angle of the parallelogram is acute. This is because the corner (corner) of the side plate pressing piece 23 does not fit in the acute angle portion after assembling into the box. If the lengths of the sides of the parallelogram are the same, a rhombus is formed.

  The stackable box of the ninth embodiment has an effect that the bottom plate 10 can be applied to a parallelogram box such as a rhombus other than a rectangle or a square.
