Description

  The present invention relates to a packaging device for packaging an object to be packaged and a packaging box for storing the packaging device.

  2. Description of the Related Art Due to the spread of mail-order sales such as online shopping, it has been frequently used to transport goods in packaging boxes using home delivery. In the transportation of these products, there is a demand for a packaging tool capable of stably supporting various packaging objects inside the packaging box.

  2. Description of the Related Art As a packaging device of this type, a packaging device including a rectangular plate-shaped member and a tubular flexible film member into which the plate-shaped member is inserted along a longitudinal direction is conventionally known (Patent Document 1). 1).

  In this packaging device, the plate-shaped member is bent to be connected to the mounting portion on which the object to be packed is mounted and to the upper edge of the mounting portion via the first valley fold line extending along the longitudinal direction. And a standing portion connected to the left and right edges of the mounting portion via a pair of second valley fold lines extending along the lateral direction of the plate-shaped member.

  In such a packaging device, first, when the bent portion is bent above the mounting portion by the first valley fold line, the mounting portion has a length corresponding to the length of the bent portion (width in the lateral direction). Since a gap increases between the film member and the film member, the object to be packaged can be inserted from the gap and placed on the placement section.

  Next, when each upright portion is bent upward at the second valley fold line, the first valley fold line that has been bent earlier is restored to the original state that has not been bent. At this time, since the lower edge of the mounting portion and the upper edge of the bent portion are relatively separated from each other, the film member is separated by the lower edge of the mounting portion and the upper edge of the bent portion. Then, it is pulled from the inner surface side in the short direction and tensed, and the object to be packaged is pressed against the mounting portion and supported.

Patent No. 6216963

  However, in this packaging device, a gap is generated between the mounting portion and the film member according to the length of the bent portion. For example, when packaging a packaging object having a height, the bent portion is formed. It needs to be longer. In this case, the width of the entire plate-like member in the short direction becomes long, and as a result, there is a disadvantage that the size of the packaging box for storing the packaging tool must be increased.

  In view of the above, an object of the present invention is to reduce the size of a packaging device and a packaging box that stores the packaging device.

  In order to achieve the above object, a plate-shaped member made of corrugated cardboard on which an object to be packaged is placed, and a tube that covers the object to be packaged, into which the plate-shaped member is inserted and placed on the plate-shaped member And a plate-like member, wherein the plate-like member has an object to be packaged by a first valley fold line connecting opposing edges of the plate-like member along the axial direction of the thin-film member. The mounting portion is divided into a mounting portion to be mounted and an upright portion adjacent to the mounting portion, and the upstanding portion is connected to the mounting portion through the first valley fold line, and is connected to the mounting portion by the first valley fold line. An upright base bent over the mounting portion, and a leading edge of the upright base connected to the upright base via a first mountain fold line extending along the first valley fold line; And a second valley extending along the first mountain fold line at a leading edge of the connecting portion. And a pressing portion which is connected to the thin film member supporting the packaging object by being bent toward the front surface side of the connecting portion by the second valley fold line and pressing the inner surface of the thin film member toward the back surface of the mounting portion. It is characterized by the following.

  In the packaging device of the present invention, the plate-like member is inserted into the tubular thin-film member, and the plate-like member can bend the upright portion above the mounting portion by the first valley fold line. it can. Thereby, in the packaging device of the present invention, since the gap between the placing portion and the thin film member increases by the length from the base end to the tip of the upright portion, the object to be packaged is inserted from the gap. It can be mounted on the mounting part.

  The upright portion is connected from the placing portion in the order of the upright base portion via the first valley fold line, the connecting portion via the first valley fold line, and the pressing portion via the second valley fold line. Therefore, it can be bent alternately with mountain fold and valley fold.

  Then, the pressing portion provided at the tip presses the inner surface of the thin film member supporting the packaging object toward the back surface of the mounting portion by the restoring force of the cardboard, and further presses the packaging object against the mounting portion. And certainly support it. Also, at this time, since the upright portion is alternately bent with the mountain fold and the valley fold, the length is shorter than when the erected portion is extended to be parallel to the mounting portion.

  Therefore, according to the packaging device of the present invention, the packaging device can be downsized.

  In the present invention, it is preferable that the connecting portion has a protrusion extending from a leading edge of the connecting portion in a connecting direction of the pressing portion.

  According to this, since the protruding portion extends from the tip end edge of the connecting portion along the connecting direction of the pressing portion, the first mountain fold line serving as a rotation axis rather than pushing the connecting portion itself downward. Pushing the protrusions apart from the lower side allows the connecting portion to be bent toward the back side of the upright base portion with a smaller force.

  Further, in the packaging tool having a projection, it is preferable that the length from the base end to the tip of the projection is smaller than the length from the base end to the tip of the pressing portion.

  According to this, when the rising portion is bent upward by the first valley fold line above the mounting portion and the leading edge of the pressing portion is towed by the thin film member, when the projection portion is pressed downward, the pressing portion is pressed. While the portion is valley-folded by the thin film member, only the connecting portion can be bent toward the back side of the upright base.

  Further, in the packaging device having a protrusion, the mounting portion includes a third mountain fold line extending at a predetermined distance from a region where the protrusion is overlapped on the back surface of the mounting portion and the protrusion. It is preferable that a cut portion is formed to connect both ends of the third mountain fold line through a region where the portions are overlapped, and a lock portion for holding the projection together with the back surface of the placing portion is provided.

  According to the packaging device having this configuration, the protrusion can be held by the lock portion, so that the upright portion can be held in a bent state.

  Further, in the packaging device of the present invention, the flap may be connected to an edge extending over the placing portion and the upright base portion via a second fold line extending in a direction intersecting the first valley fold line. preferable.

  According to the packaging device having this configuration, by bending the flap along the second fold line, the first valley fold line extending in the direction intersecting with the second fold line is restored to the original state without being bent. You. Thus, the upright base extends parallel to the mounting portion, and the inner surface of the thin film member can be pressed by the leading edge of the upright base, so that the object to be packaged can be further pressed against the mounting portion and securely supported. it can.

  The packaging box according to the present invention is characterized in that the packaging device is housed inside.

  In the packaging device, since the horizontal length from the base end to the distal end of the upright portion can be shortened, according to the packaging box of the present invention, the packaging box itself can be downsized.

  Further, in the packaging box for storing therein the packaging device having the flap, the inner dimension of one side of the packaging box is larger than the length of the placing section in the direction along the first valley fold line, and It is preferable that the length of the mounting portion is smaller than the length obtained by adding the length from the base end to the front end of the flap.

  According to the packaging box having this configuration, the flap can be held in a folded state only by storing the packaging tool in which the flap is folded inside the packaging box.

  The plate-shaped member 2 includes a horizontal rectangular mounting portion 21, a horizontal rectangular upright portion 22 connected to the upper edge of the mounting portion 21, and a pair of right and left edges of the mounting portion 21. And a vertically long rectangular flap 23.

  The plate-shaped member 2 is provided with a valley fold line a (corresponding to a first valley fold line of the present invention) extending in the left-right direction along the upper edge of the mounting portion 21. The mounting section 21 and the upright section 22 are defined by the valley fold line a. Various fold lines including the valley fold line a and other fold fold lines and mountain fold lines described later are formed by providing bending grooves unless otherwise specified.

  Further, the plate-shaped member 2 has a flap fold line b (corresponding to a second fold line of the present invention) extending in the vertical direction along the left and right edges of the mounting portion 21 and an upright base 221 to be described later. Is provided.

  The placement unit 21 is a part on which the packaging target A is placed. The mounting portion 21 is provided with a pair of lock portions 211 on both left and right sides.

  The lock portion 211 includes a mountain fold line c (corresponding to a third mountain fold line of the present invention) extending in the left-right direction from the left and right edges near the center in the vertical direction of the mounting portion 21 toward the center. A substantially inverted “U” -shaped notch 212 connecting both ends of the line b is formed.

  The upright portion 22 includes an upright base 221 connected to the upper edge of the mounting portion 21, a connecting portion 222 connected to the upper edge of the upright base 221, and a pressing portion connected to the center of the upper edge of the connecting portion 222. 223, and a pair of protrusions 224 on the left and right sides of the pressing portion 223 at the upper edge of the connecting portion 222. In the center of the upright portion 22, an opening 225 having a vertically long and substantially rectangular shape is formed extending from the base end of the pressing portion 223 to the base end of the upright base 221.

  The upright base portion 221 is connected to the upper end edge of the placing portion 21 via the valley fold line a. The upright base portion 221 is bent above the mounting portion 21 (front surface side) by the valley fold line a.

  The connecting portion 222 is connected to the upper edge of the upright base portion 221 via the mountain fold line d. The connecting portion 222 is bent toward the back surface of the upright base portion 221 by the mountain fold line d. Since this mountain fold line d is formed by providing a cut line intermittently in a perforation, the connecting portion 222 can be folded back until it comes into contact with the back surface of the upright base 221 by the mountain fold line d.

  The pressing portion 223 is connected to the center of the upper end edge of the connecting portion 222 via the valley fold line e. The pressing part 223 is bent toward the surface of the connecting part 222 by the valley fold line e.

  The protruding portion 224 is connected to the upper edge of the connecting portion 222 via the fold line f. The protrusion 224 is provided in a pair at the left and right ends of the upper end edge of the connecting portion 222 so as to sandwich the pressing portion 223. Since the fold line f is formed by providing a cut line intermittently in a perforation, the protrusion 224 can be folded in a mountain and a valley, and when the valley is folded, the protrusion 224 is brought into contact with the back surface of the mounting portion 21. Can be folded.

  The mountain fold line c of the lock portion 211 is provided at a position extending at a predetermined distance from the overlapping region so as not to pass through the region of the mounting portion 21 overlapping the folded protrusion 224, and The cut 212 of the portion 211 is provided at a position passing through a region overlapping with the folded protrusion 224.

  The flap 23 is connected to the mounting portion 21 and the left and right edges of an upright base portion 221 described later via a flap fold line b. The flap 23 is bent above (on the front side of) the mounting portion by the flap fold line b.

  Each flap 23 is formed with a substantially inverted “U” -shaped cut 231 having both ends on the base end edge. The flap fold line b extends vertically from each end of the cut 231.

  The flexible film 3 is formed of, for example, a flexible film made of a synthetic resin film such as polyethylene terephthalate, polyethylene, polypropylene, polycarbonate, and polyvinyl chloride. The flexible film 3 is cylindrical or bag-shaped, and the plate-like member 2 is inserted from the opening along the longitudinal direction.

  The flexible film 3 needs to be formed to have a length that covers at least a part of the packaging object A in the axial direction, and in the present embodiment, all of the pressing part 223 and part of the protruding part 224 are formed. It is formed so as to be covered.

  The length of the flexible film 3 in the circumferential direction is designed to be equal to or slightly larger than the outer circumference of the plate-shaped member 2 in the short direction so as to accommodate the plate-shaped member 2. The flexible film 3 is flexible and can be expanded and contracted, and the plate member 2 can be bent along the fold line d. The film 3 can be designed to be slightly smaller. That is, the length of the flexible film 3 in the circumferential direction can be appropriately selected according to the size of the packaging object A to be stored.

  In the present embodiment, the plate-like member 2 is only inserted into the flexible film 3 and is not fixed. However, the present invention is not limited to this. The plate member 2 on the side and the flexible film 3 can be fixed with an adhesive and heat welding.

  Next, a procedure for packaging the packaging object A using the packaging tool 1 will be described with reference to FIGS.

  First, as shown in FIGS. 3 and 4, the upright base 221 of the plate-like member 2 is valley-folded along the valley fold line a, and the entire upright portion 22 is bent above the mounting portion 21 (surface side).

  As a result, the vertical width of the plate-shaped member 2 is reduced by the vertical width of the upright portion 22, and therefore at least the vertical portion of the upright portion 22 is provided between the placing portion 21 and the flexible film 3. A gap corresponding to the width in the direction is generated. Then, as shown in FIG. 4, the packaging object A is inserted into the gap between the loosened flexible film 3 and the mounting portion 21.

  Next, as shown in FIGS. 4 and 5, in order to bend the connecting portion 222 toward the back surface of the upright base 221 along the mountain fold line d, the upright base 221 is pushed obliquely downward with the mountain fold line d as a rotation axis.

  At this time, since the leading edges of the pressing portion 223 and the protrusion 224 are locked to the flexible film 3, if only the connecting portion 222 is pushed in the direction of bending the rear surface of the upright base 221, the pressing portion 223 and the protrusion The unit 224 tries to maintain the posture. Therefore, as shown in FIG. 5, the pressing portion 223 and the protruding portion 224 are valley-folded along the valley fold line e and the fold line f in a direction relatively approaching the surface side of the connecting portion 222.

  Further, as shown in FIG. 6, the connecting portion 222 is folded back along the mountain fold line d until it comes into contact with the back surface of the standing base 221.

  Next, as shown in FIG. 6, the protrusion 224 that is valley-folded in a direction approaching the surface side of the connecting portion 222 by the fold line f is placed in the opposite direction by the fold line f as shown in FIG. Fold it in a mountain until it contacts the back of the part 21.

  Next, as shown in FIG. 6, each lock portion 211 is pushed under the mounting portion 21 (from the front surface to the back surface side), and is mountain-folded along the mountain fold line c.

  At this time, since the notch 212 of the lock portion 211 is provided at a position passing through a region overlapping with the folded protrusion 224, when the lock portion 211 is pushed downward, the protrusion 224 is formed by the outer edge of the lock portion 211. Is also bent at the fold line f and pushed downward. Since the mountain fold line c of the lock portion 211 is provided at a position that does not pass through an area of the placing portion 21 that overlaps the folded protrusion 224, the outer edge of the lock portion 211 exceeds the back surface of the protrusion 224. Then, the protrusion 224 returns to the direction in contact with the back surface of the mounting portion 21 by the restoring force of the cardboard.

  Then, when the pressing of the lock portion 221 is finished, the lock portion 221 also returns to the original position by the restoring force of the cardboard, and as shown in FIG. Sandwiched between the surface.

  Next, as shown in FIGS. 6 and 7, the flap 23 is bent above the mounting portion 21 (front surface side) along the fold line b. As a result, the fold line a is orthogonal to the fold line b, so that the fold line is extended from the valley-folded state to the original state.

  Thus, the packaging of the packaging target A using the packaging tool 1 is completed.

  According to the packaging device 1 described above, as shown in FIG. 8, the flexible film 3 is pulled downward from the inner peripheral surface side by the pressing portion 223 trying to expand by the restoring force of the cardboard. Tension is applied, and the packaging object A is pressed against the mounting portion 21. Thereby, the packaging object A is fixed at a predetermined position.

  As shown in FIG. 8, a portion of the upright portion 22 except for the upright base portion 221 is folded back to the back surface side of the mounting portion 21, so that the entire upright portion 22 extends in a shorter direction than a conventional packaging tool. Of FIG. 8 (in the left-right direction in FIG. 8) can be reduced.

  In addition, as shown in FIGS. 7 and 8, since the protrusion 224 can be sandwiched between the back surface of the mounting portion 21 and the surface of the lock portion 221, the upright portion 22 can be held in a bent state.

  Further, since the opening portion 225 is formed in the upright portion 22 from the base end edge of the pressing portion 223 to the base end edge of the upright base portion 221, the corrugated cardboard folded when the upright portion 22 is bent a plurality of times. Can escape into the internal space of the opening 225, so that it is easy to bend.

  Further, since the flap 23 is provided at an end in the longitudinal direction of the mounting portion 21, even when the cylindrical object to be packaged is mounted along the longitudinal direction of the mounting portion 21, the flexible material is flexible. The placing section 21 can be prevented from being bent along the longitudinal direction due to the tension of the film 3.

  Further, since the notch 231 is provided at the base end of the flap 23, when the flap 23 is bent above the mounting portion 21 (front side) along the fold line b, the inside of the notch 231 (the mounting portion The area 21) extends along the mounting portion 21 without being bent. Thus, when the flap 23 is to be restored in the horizontal direction from the bent state, the opening edge formed by the cut 231 of the flap 23 is neglected at the edge of the inner area of the cut 231 connected to the mounting portion 21. You. As a result, in the packaging device 1, the flap 23 is held in a folded state.

  In addition, in the packaging device 1, as shown in FIG. 8, the upright base 221 and the connecting portion 222, which are folded back so as to be in contact with each other, are simply folded back so as to be in contact with the surface of the mounting portion 21. Since the length in the short direction is reduced and the flexible film 3 is loosened, the packaging object A can be taken out.

  Finally, as shown in FIG. 1, the packaging device 1 is housed in the outer box 4 and the top is closed, whereby the packaging of the packaging box 10 is completed.

  The inner dimension of the outer box 4 in the short direction is larger than the length of the mounting portion 21 and the upright base 221 in the short direction, and smaller than the entire length of the plate member 2 in the short direction.

  The inner size of the outer box 4 in the longitudinal direction is larger than the length of the mounting portion 21 in the longitudinal direction and smaller than the length of the entire plate-like member 2 in the longitudinal direction.

  Therefore, in the packaging box 10, the outer box 4 having a smaller area in the horizontal direction than the outer box for packing the conventional packaging tool 1 can be used.

  Hereinafter, modified examples of the plate-shaped member 2 according to the packaging device 1 of the present invention will be described.

  For example, the fold lines including the valley fold line and the mountain fold line of the present embodiment can be appropriately selected, such as a fold line and a cut line provided with intermittent perforations.

  In the present embodiment, the flaps 23 connected to the left and right edges of the mounting portion 21 and the upright base portion 221 are illustrated, but the flaps 23 may be connected only to the left and right edges of the mounting portion 21. Further, the flap 23 may be provided on any one of the left and right edges, or may be omitted and not provided.

  In the present embodiment, the flap 23 is trough-folded at the fold line b, but may be mountain-folded at the fold line b. According to this configuration, since the flap 23 extends downward together with the pressing portion 223 and can separate the mounting portion 21 from the bottom plate of the outer box 4, the packaging target A is protected from external impact. Can be.

  In the present embodiment, the lock portion 211 has a substantially rectangular shape, but the lock portion 211 is not limited to this. For example, a hole may be simply provided and the tip of the protrusion 224 may be inserted. Further, the lock unit 211 may be omitted.

  In the present embodiment, the vertically elongated substantially rectangular opening 225 extending from the base edge of the pressing portion 223 to the base edge of the upright base 221 is illustrated, but the opening 225 is not limited to this, and is parallel to the fold line. Alternatively, it is sufficient to provide them so as to intersect or to provide them adjacent to the fold line. Further, the opening 225 may be omitted.

  In the present embodiment, an example in which the connecting portion 222 is folded until it comes into contact with the back surface of the upright base portion 221 has been described. However, the connecting portion 222 is not limited thereto, and the entire upstanding portion 22 may be bent in a bellows shape.

  In the present embodiment, the pressing portion 223 is connected to the central portion of the upper edge of the connecting portion 222. However, the pressing portion 223 is not limited to the central portion as long as it is connected to the upper edge of the connecting portion 222. The length may exceed the connecting part 222.

  In the present embodiment, the protrusion 224 is illustrated as being connected to the upper end edge of the connecting portion 222 via the fold line f, but the fold line f may be omitted. According to this, since the mountain fold line d can be bent from a farther position by pushing the projection 224, the connecting portion 222 can be bent with a smaller force.

  Further, in the present embodiment, as the protrusion 224, one having the same length (up and down direction in FIG. 2) as the pressing portion 223 is exemplified, but the protrusion 224 is not limited to this, and for example, the pressing portion 223 Can be shorter than According to this, when the valley-folded protrusion 224 is mountain-folded in the reverse direction, it is possible to reduce the possibility that the flexible film 3 is hooked. The number of the protrusions 224 may be one instead of a pair, or may be omitted.
