  2. Description of the Related Art There has been known a folding box which is formed so as to be able to open and close a swing outlet for swinging out contents stored in a carton. Patent Literature 1 discloses a folding box in which a locking claw 30 is formed at the tip of a substantially fan-shaped guide piece 15a connected to a lid plate. During the opening of the cover plate, the locking claw 30 is locked in the folding box, and the rotation of the cover plate stops there.

JP-A-2000-95282

  Since the movement of the lid plate is stopped by the locking claw 30, the lid plate and the guide piece are prevented from falling out of the folding box. However, the locking claw of Patent Document 1 is small, and the structure is slightly complicated. In addition, high dimensional accuracy is required for the shape, formation position, protrusion height, and the like of the locking claw.

  SUMMARY OF THE INVENTION An object of the present invention is to make it difficult for a pivotable lid to be detached from a carton when fully opened with a simple structure.

  Another object of the present invention is to be able to stop the rotation of the rotary opening / closing lid at any stage during the full closing, the full opening, and the middle thereof.

  Another object of the present invention is to enable a large outlet to be formed.

  A drawer carton according to the present invention includes opposed front and rear panels, opposed left and right side panels, opposed top and bottom panels, and these panels form a rectangular parallelepiped space inside. At least a part of the top panel is rotatable upward, and the rotation range of the top panel is used as a rotation opening / closing lid for opening / closing a swing outlet. A pair of turning wall portions extending in a direction perpendicular to the turning opening / closing lid and located in the carton, are connected to each other, and the turning opening / closing cover and the pair of turning wall portions are turned upward. It is noted that a spacer piece bent inward and sandwiched from both sides by the pair of rotating wall portions is continuously provided on the upper edge of the panel that defines the lower edge of the outlet formed by the movement. To. Preferably, the drawn carton of the present invention is made from a single cardboard, plastic sheet, or composite thereof.

  The top panel may be entirely rotated or a part thereof may be rotated.

  To rotate the entire top panel, connect one end of the top panel to the upper end of either the left or right side panel, or the upper end of either the front or back panel via a fold line. do it. For example, if one end of the top panel is connected to the upper end of the right panel, the entire top panel can be rotated with the folding line at the boundary with the right panel as the rotation axis. In this case, the swing outlet is formed with an alligator on the left side panel, and the entire top panel becomes a rotary opening / closing lid. One end of the top panel may be connected to the upper end of the back panel via a folding line, for example. The top panel rotates about the boundary with the rear panel as a rotation axis, and the outlet is formed by the front panel.

  By forming a folding line on the top panel and using the folding line as a rotation axis, a part of the top panel can be rotated. In this embodiment, not the entire top panel but a part thereof is used as a rotary opening / closing lid.

  A pair of rotating wall portions located in the rectangular parallelepiped carton and extending in a direction perpendicular to the rotating opening / closing lid are continuously provided on both side ends of the rotating opening / closing lid. When it is moved, the rotating wall portion also rotates. When the rotation opening / closing lid is rotated upward, a pair of rotation wall portions are pulled out from the inside of the carton and gradually exposed to the outside.

  According to the present invention, a panel (a left side panel, a right side panel, a front panel or a panel) defining a lower edge of a swing outlet formed by rotating the rotation opening / closing lid and the pair of rotation wall portions upward. At the upper edge of one of the back panels), a pair of spacer pieces that are bent inward and sandwiched from both sides by the pair of rotation wall sections are continuously provided. This prevents the pair of rotating wall portions from falling inward (tilting).

  For the sake of simplicity, consider a state in which there is no spacer piece. As described above, the pair of rotating wall surfaces are connected to both side ends of the top panel and extend in a direction orthogonal to the rotating opening / closing lid and are located in the rectangular parallelepiped carton. There is no support between the pair of rotating wall portions on the side opposite to the side connected to the top panel. For this reason, when the pair of turning wall portions drawn out by turning the turning opening / closing lid upward is pushed inward, the pair of turning wall portions assume an oblique posture in a direction approaching each other. If the pair of rotating wall portions take an oblique posture in a direction of approaching each other, the rotating wall portion interferes with the content, and it is difficult to swing out the content from the outlet. In addition, the rotating wall portion easily comes out of the carton.

  According to the present invention, since the spacer piece is sandwiched between the pair of turning wall portions, the pair of turning wall portions is prevented from taking an oblique posture. For this reason, it is possible to prevent the rotating wall portion from interfering with the contents or easily coming out of the carton. Furthermore, even if the rotation opening / closing lid is rotated to a large rotation angle, the rotation wall portion is difficult to be pulled out of the carton, so that it is easy to make a large outlet.

  Furthermore, since each of the pair of rotating wall portions can be sandwiched between the both sides of the spacer piece and the inner surface of the panel forming the carton, the rotating opening / closing lid can be easily locked at an arbitrary rotating position by frictional force. (Stop motion). The rotary opening / closing lid can be locked not only at the fully open position and the fully closed position but also at a halfway open position, for example, in the middle thereof, so that the size of the swing outlet can be easily adjusted.

  In addition, when the pivotable opening / closing lid is closed, the pivoting lid can be vertically overlapped with the spacer piece. For example, when the pivotable opening / closing lid is further pushed downward from the fully closed position, the pivotable opening / closing lid is opened. The lid is less likely to fall into the carton, improving stability in the fully closed position.

  Preferably, each of the outer edges of the pair of rotating wall surfaces has an arc-shaped outer edge continuous with the rotating opening / closing lid and a linear outer edge continuous with the arc-shaped outer edge. In the course of rotating the pair of rotating wall portions upward, the straight outer edge linearly contacts the panel defining the lower edge of the outlet in the carton. It is possible to effectively prevent the rotating wall portion from falling out of the carton. Further, since the contact is made linear, the stability at the fully open position is also improved.

  In one embodiment, a finger hook that projects outward beyond a panel that defines a lower edge of the swing opening when the rotary opening / closing lid is closed is continuously provided at a tip of the rotary opening / closing lid. I have. It is easy to put the finger on the finger hook and pull up the pivoting lid.

  FIG. 1 is an exploded view of a pattern (blank) that forms a dispensing carton, as seen from the inside surface of the dispensing carton. Cardboard, plastic sheets, or composites thereof are die cut into the shape shown in FIG. The dashed line shown in FIG. 1 indicates a fold line that is valley-folded when the dispensing carton is assembled. In order to facilitate bending, folding and crease processing are performed along a dashed line.

  A vertically elongated glue allowance panel 11, a back panel 12, a right side panel 13, a front panel 14, and a left side panel 15 having the same height are horizontally connected via a folding line. The front and rear panels 12, 14 are equal in size, and the left and right side panels 13, 15 are also equal in size. The width of the left and right side panels 13, 15 is smaller than the width of the front and rear panels 12, 14.

  A top panel 22 is connected to the upper end of the right side panel 13 via a folding line. Further, a pair of rotating wall portions 21 and 23 are respectively connected to left and right ends of the top panel 22. A cut is made between each of the pair of rotating wall portions 21 and 23 and the upper edge of the rear surface and the front panels 12 and 14, and the rotating wall portions 21 and 23 and the rear surface and the front panels 12 and 14 are cut. Is not connected.

  The width of the top panel 22 is equal to the width of the right side panel 13 or slightly smaller than the width of the right side panel 13. The length of the top panel 22 is substantially equal to the width of the front and rear panels 14, 12. Further, the tip portion of the top panel 22 (the side opposite to the side connected to the right side panel 13) protrudes outward slightly in an arc shape. The arc-shaped protruding portion at the tip of the top panel 22 is hereinafter referred to as a finger hook 22a.

  The turning wall portions 21 and 23 are generally fan-shaped, but the entire outer edge is not arcuate. Focusing on the outer edges of the rotating wall portions 21 and 23, the arc-shaped outer edges 21a and 23a connected to the tip of the top panel 22, the oblique straight outer edges 21b and 23b extending obliquely straight along the way, and finally the angle is slightly sharpened. Instead, the outer edges of the rotating wall portions 21 and 23 are defined by the straight outer edges 21c and 23c facing the rear and front panels 12 and 14, respectively.

  A spacer piece 24 is connected to the upper end of the left side panel 15 via a folding line. Details of the spacer pieces 24 will be described later.

  An inner bottom panel 31 is connected to the lower end of the rear panel 12 via a fold line, and an outer bottom panel 33 is connected to the lower end of the front panel 14 via a fold line. Flaps 32 and 34 are respectively connected to lower ends of the right side panel 13 and the left side panel 15.

  An assembling procedure of the dispensing carton 1 will be described. First, the pair of rotating wall portions 21 and 23 are valley-folded substantially perpendicularly to the top panel 22 so as to face each other, and then the top panel 22 is valley-folded substantially perpendicularly to the right side panel 13. The spacer piece 24 is folded inward at a substantially right angle valley, and then the glue allowance panel 11, the rear panel 12, the right side panel 13, the front panel 14, and the left side panel 15 are substantially perpendicular to the adjacent panel. Fold each valley. The spacer piece 24 is sunk under the top panel 22 and is sandwiched between the pair of rotating wall portions 21 and 23. The left side panel 15 and the glue margin panel 11 are overlapped and bonded so that the left side panel 15 is on the outside and the glue margin panel 11 is on the inside, whereby a rectangular parallelepiped shape with an open bottom is formed. The contents are placed from the opening bottom.

  After the contents have been inserted, the two flaps 32 and 34 are folded at substantially right angles, and then the inner bottom panel 31 and finally the outer bottom panel 33 are substantially folded at right angles. The bottom portion is closed by the inner and outer bottom panels 31, 33 by bonding the overlapping inner bottom panel 31 and outer bottom panel 33. The cuboid carton 1 is completed (FIG. 2). The bottom may be a sack type instead of the above-mentioned adhesive (seal) type.

  Referring to FIG. 3, when the user puts a finger on the finger hook 22 a at the tip of the top panel 22 and raises the top panel 22, the top panel 22 moves upward with the boundary with the right side panel 13 as an axis. Rotate. Since the rotating wall portions 21 and 23 are connected to the left and right ends of the top panel 22, when the top panel 22 is rotated, the rotating wall portions 21 and 23 also rotate together with the top panel 22. The rotating wall portions 21, 23 contained in the carton 1 are gradually exposed to the outside.

  By rotating the top panel 22 upward, the top edge of the top panel 22, the top edges (outer edges) of the rotating wall portions 21 and 23, and the top panel of the left panel 15 are located above the left side panel 15. A substantially rectangular outlet K (a passage surrounded by the top panel 22 and the rotating wall portions 21 and 23) connected to the inner space of the carton 1 surrounded by the upper edge is formed. The contents contained in the carton 1 can be spun out from the outlet K. As described above, the top panel 22 functions as a rotary opening / closing lid that opens and closes the outlet K of the carton 1.

  If the top panel 22 continues to be raised, the oblique straight outer edges 21b and 23b of the rotating wall surfaces 21 and 23 hit the inner surface of the left side panel 15 in the carton 1, and the rotation of the top panel 22 stops there. The fully open state of the top panel 22 is defined by the oblique straight outer edges 21b and 23b of the rotating wall portions 21 and 23. Since the oblique straight outer edges 21b and 23b hit the left side panel 15 linearly, the stability of the fully opened state is good.

  Further, in the carton 1, as described above, the spacer pieces 24 connected to the upper end of the left side panel 15 are bent inward, and the spacer pieces 24 bent inward by the rotating wall surfaces 21 and 23 are separated from both sides. It is sandwiched. For this reason, the rotating wall portions 21 and 23 do not incline (fall down) and continue to be folded at a substantially right angle to the top panel 22, and follow the inner surfaces of the rear panel 12 and the front panel 14. Keep the state. If the spacer piece 24 is not provided, the rotating wall portions 21 and 23 that are drawn out are easily inclined inward, and when inclined inward, the rotating wall portions 21 and 23 interfere with the contents and shake the contents. Although it is difficult to swing out from the outlet K and the turning wall portions 21 and 23 can easily come out of the carton 1, the inward inclination of the turning wall portions 21 and 23 is prevented by the spacer pieces 24, so that the turning There is no interference between the wall portions 21, 23 and the contents, and the rotating wall portions 21, 23 do not fall out of the carton 1.

  One rotating wall portion 21 is sandwiched between the inner surface of the back panel 12 and one end of the spacer piece 24, and the other rotating wall portion 23 is sandwiched between the inner surface of the front panel 14 and the other end of the spacer piece 24. It is sandwiched between. That is, the rotating wall portions 21 and 23 slide between the both ends of the spacer piece 24 and the inner surfaces of the front and back panels 14 and 12. Therefore, regardless of whether the top panel 22 is fully opened (the state shown in FIG. 3) or the top panel 22 is rotated about halfway, the top panel 22 is held at that position by frictional resistance. Locking can be easily performed, and the size of the outlet K can be adjusted.

  When the top panel 22 is pivoted upward, the spacer pieces 24 are gradually inclined upward from the state of being bent inward at a substantially right angle (the bending angle becomes shallower). However, even if the top panel 22 is fully opened, the pinching by the rotating wall portions 21 and 23 does not completely come off. When the top panel 22 is pivoted downward to close the outlet K, the spacer pieces 24 return to a state in which the spacer pieces 24 are folded inward at substantially right angles.

  When the top panel 22 is completely closed, the top panel 22 and the spacer pieces 24 overlap vertically, so that the stability of the fully closed state is good. For example, even if the top panel 22 in the fully closed state is pushed downward, the top panel 22 is unlikely to fall into the carton 1.

  Instead of using the entire top panel 22 as the pivoting lid, a part of the top panel 22 may be used as the pivoting lid. FIG. 4 shows that the top panel 22 is substantially bisected by a fold line 28 extending in a direction connecting the rear panel 12 and the front panel 14, and a part of the bisected top panel 22 on the left side panel 15 side. 1 shows a modified carton 1A in which a top panel 22b in the range shown in FIG. Since the outlet K is smaller than the output carton 1, the length of the spacer piece 24 is shortened accordingly.

  Further, it is not always necessary to fold the spacer pieces inward at a right angle, as shown in the modified carton 1B (the top panel 22 and the rotating wall portions 21, 23 are omitted) shown in FIG. In addition, a spacer piece 25 that is bent so as to have an obliquely upward attitude may be formed. Further, when the top panel 22 is closed, as shown in FIG. 6, the top of the obliquely upward spacer piece 26 is connected to the tip of the obliquely upward spacer piece 26 via a fold line, as in the case of the dispensing carton 1 </ b> C of another modified example. Alternatively, a spacer piece 27 that is in a posture parallel to the top panel 22 may be formed. Supports for preventing the rotation wall portions 21 and 23 from inwardly tilting over a relatively long distance are formed by the spacer pieces 26 and 27.

  FIGS. 7 to 10 show modified examples of spacer pieces having various shapes, which are provided continuously at the upper end of the left side panel 15. As shown in FIGS. 7 to 10, the spacer pieces may not be limited to squares. As shown in FIG. 7, a trapezoidal spacer piece 24A may be used, or as shown in FIG. 8, an inverted trapezoidal spacer piece 24B may be used. Further, a spacer piece 24C having a shape that bulges outward in both sides as shown in FIG. 9 and a spacer piece 24D having a shape bulging in both sides only at the tip portion as shown in FIG. Of the spacer pieces 24A to 24D shown in FIGS. 7 to 10, the spacer pieces 24B to 24D shown in FIGS. 8 to 10 have a width wider than the width of the left side panel 15, so that they are curved upward or downward in the carton. Needless to say.
