Description

  The present invention relates to a suspended package in which a box-shaped main body having an accommodation space is suspended and installed.

  Suspended packages for suspending and displaying various items such as food, daily necessities or electronic devices are provided. Patent Document 1 describes a packaging box (suspended package) in which a suspended piece is formed at each end of a pair of flaps extending from a short side (thickness direction) side of a rectangular parallelepiped main body. ing. In this packaging box, a first top plate is formed by folding and overlapping a pair of flaps, and the suspended pieces overlap each other. And a suspension piece protrudes from a main body by inserting a suspension piece in the slit formed in the top plate (2nd top plate) extended from the side of the longitudinal direction (width direction) of a main body.

  Patent Document 2 describes a suspended package in which a suspended piece is formed on a first top plate extending from a side in the longitudinal direction (width direction) of a rectangular parallelepiped main body. In this package, the suspended piece stands from the first top plate by folding the first top plate into a mountain and a valley. And like the packaging box concerning patent document 1, a hanging piece is a main part by inserting a hanging piece in the slit formed in the 2nd top plate extended from the opposite side of the longitudinal direction (width direction) of a main part. Protrude from.

  These packages include a double top plate including a first top plate on which a suspension piece is formed, and a second top plate that closes the upper end opening of the main body and penetrates the suspension piece. This double top plate supports the weight of the package when the main body is suspended.

  However, these packages have a problem that the top plate bends due to the temporal deformation when installed in a suspended state, and the main body bulges upward. This is because, when the suspended piece is hung on a hook, for example, the weight of the main body and the contents are concentrated on the base of the suspended piece, and thus the first top plate is bent upward and convex. is there. Although the second top plate is disposed above the first top plate, the concentrated load at the base of the suspended piece is also concentrated in the vicinity of the slits of the second top plate, so the second top plate Bending deflection cannot be suppressed by the top plate, and the same bending deflection is generated in the second top plate. For this reason, the conventional package is unsuitable for hanging installation for a long period of time, and measures such as increasing the thickness of the material are necessary in order to suppress temporal deformation.

  The present invention has been made in view of the above-described problems, and provides a suspended package having excellent deformation resistance when suspended.

  The suspended package according to the present invention is a suspended package having a box-shaped main body having a housing space therein and a suspended piece for suspending and installing the main body. And a second top plate arranged opposite to the first top plate and connected to the peripheral surface of the main body, and when the main body is suspended and installed, A reinforcing portion that transmits the weight of the suspension type package applied to the suspension piece from the first top plate to the second top plate or the peripheral surface is formed by bending the main body.

  According to the above-described invention, the weight of the main body when suspended and installed is dispersed from the first top plate to the second top plate or the peripheral surface of the main body by the reinforcing portion formed by bending a part of the main body. The bulging deformation of the first top plate at the base of the suspended piece is suppressed. In addition, in the said invention, the reinforcement part being bent at the main body means that the reinforcement part is connected to at least a part of the main body in a curved or bent state, and the reinforcement part includes bending. It is not required to be manufactured by a manufacturing method.

  Note that the various components of the present invention do not have to be individually independent, that a plurality of components are formed as one member, and one component is formed of a plurality of members. That a certain component is a part of another component, a part of a certain component overlaps a part of another component, and the like.

  The suspended package of the present invention has a simple structure and is excellent in deformation resistance when suspended and can be prevented from being deformed with time even when suspended for a long period of time. For this reason, the hanging type package of the present invention suspends and installs products with a relatively long display period and relatively heavy products such as electronic devices as well as foods with a relatively short display period in relation to the expiration date and the expiration date. Especially suitable for.

FIG. FIG. 2B is an enlarged view thereof. FIG. 4 is a plan development view of the package 10. The figure shows the outer surface of the package 10.

First, an outline of the package 10 of the present embodiment will be described.
The package 10 includes a box-shaped main body 20 having an accommodation space V therein, and a hanging piece 30 for suspending and installing the main body 20.
The package 10 includes a first top plate 40 on which a suspended piece 30 is formed, and a second top plate 50 that is disposed to face the first top plate 40 and is connected to the peripheral surface 60 (rear surface 62) of the main body 20; It is equipped with.
And the package 10 of this embodiment is the reinforcement part which transmits the dead weight of the package 10 concerning the hanging piece 30 from the 1st top plate 40 to the 2nd top plate 50 or the surrounding surface 60 when the main body 20 is suspended and installed. 70 is formed by bending the main body 20.

Next, the package 10 of this embodiment will be described in detail.
The package 10 is made of a sheet material 90 such as paper or plastic (see FIG. 4). The material of the sheet material 90 is not particularly limited, but a paper material is particularly preferably used from the viewpoint of processability and recyclability. Examples of paper materials include paperboard such as coated cardboard and corrugated cardboard. Furthermore, the package 10 of the present embodiment is formed by folding and bonding a single paper material. For this reason, manufacture and recycling are easy.

  The shape of the main body 20 is not particularly limited, and corresponds to the shape and size of the accommodation P accommodated therein. In this embodiment, a rectangular parallelepiped main body 20 is illustrated. The rectangular parallelepiped shape includes a legislative shape.

  For convenience, as shown in FIG. 1A, a width direction corresponding to the in-plane direction of the front surface 61 and the rear surface 62 of the main body 20 and a thickness direction corresponding to the in-plane direction of the side surfaces 63 and 64 are defined. Also, the direction perpendicular to both the width direction and the thickness direction is defined as the height direction, and the side on which the hanging piece 30 is provided is defined as the upper side. The same applies to the height direction in the plan development view of FIG. In FIG. 4, the width direction and the thickness direction are combined to indicate the circumferential direction.

  The hanging piece 30 is a holding unit for hanging the package 10. The suspended piece 30 of the present embodiment includes a through hole 36, and a hook 110 (see FIG. 2) can be inserted through the suspended piece 30. In addition, the aspect which suspends and installs the package 10 of this embodiment is not restricted to this, The hanging piece 30 may be picked and hold | maintained with a clip etc., or a protrusion (not shown) may be held in the hanging piece 30 May be formed and hooked on a wall surface or the like.

  As shown in FIG. 1A, the suspension piece 30 penetrates the second top plate 50 and protrudes upward. The second top plate 50 is a portion that closes the upper end of the peripheral surface 60, and is locked so as to be opened and closed by a folding piece 65 that is bent inside the main body 20. The folding piece 65 is connected to the upper portion of the front surface 61 of the main body 20.

  The first top plate 40 and the second top plate 50 face each other, and the main body 20 includes an upper hollow structure HT surrounded by the first top plate 40, the second top plate 50 and the peripheral surface 60. The reinforcing portion 70 suppresses the compressive deformation of the upper hollow structure HT, so that the deformation of the package 10 with time is suppressed.

  As shown in FIGS. 1B and 4, the first top plate 40 and the suspension piece 30 are connected to the upper side of the front surface 61, and the second top plate 50 is connected to the upper side of the rear surface 62. Yes. Further, flaps 72 are connected to the upper sides of the side surfaces 63 and 64, respectively. The first top plate 40, the second top plate 50, and the flap 72 are used by being bent at right angles to the peripheral surface 60 (the front surface 61, the rear surface 62, and the side surfaces 63, 64). In the plan development view of FIG. 4 showing the outer surface of the package 10, a two-dot chain line represents a mountain fold line, and a dotted line represents a valley fold line. The hanging piece 30 is used by being folded in two and overlapping.

  That is, the main body 20 of the present embodiment has a rectangular parallelepiped shape and is formed by extending the flaps 72 to other peripheral surfaces (side surfaces 63 and 64) different from the peripheral surface 60 (rear surface 62) to which the second top plate 50 is connected. Has been. And the reinforcement part 70 of this embodiment is formed by folding up the front-end | tip (end edge part 73) of the flap 72 at substantially right angle.

  The reinforcing portion 70 holds the suspension piece 30 and suspends the main body 20 from the circumferential surface 60 by applying a load concentrated on the root portion of the suspension piece 30 to the circumferential surface 60 or via the second top plate 50. Is formed by bending a part of the main body 20.

  The reinforcing portion 70 of the present embodiment is formed by bending a part (end edge portion 73) of the main body 20 upright in a direction perpendicular to the first top plate 40. Thereby, the time-dependent bending deformation | transformation of the 1st top plate 40 in which the suspension piece 30 was formed is suppressed.

  As shown in FIG. 1B, the hanging piece 30 has a flat shape formed by bending the first top plate 40. The reinforcing portion 70 extends in the thickness direction of the hanging piece 30. Therefore, the weight of the package 10 concentrated along the root portion 38 corresponding to the fold line (valley fold line) of the hanging piece 30 is the thickness of the first top plate 40 with the reinforcing portion 70 (end edge portion 73) as a rib structure. Distributed in the vertical direction.

  As shown in FIG. 2, the edge portion 73 is formed in a band shape at the tip of a flap 72 extending from the upper ends of the side surfaces 63 and 64, and the width dimension of the band shape (corresponding to the height dimension in FIG. 2) is It is equal to the facing distance between the first top plate 40 and the second top plate 50. For this reason, when the package 10 is suspended from the hook 110 and the root portion 38 is pulled up, the weight of the package 10 is dispersed within the band-like surface of the end edge portion 73, and the force that pushes up the second top plate 50 as a whole. Is replaced by The force pushing up the second top plate 50 is distributed and transmitted from the second top plate 50 to the rear surface 62 and from the second top plate 50 to the front surface 61 through the folding piece 65. Therefore, when the package 10 of this embodiment is suspended and installed, the first top plate 40 is prevented from being bent upward and deformed by its own weight. In the present embodiment, the edge portion 73 that is a part of the main body 20 is bent to constitute the reinforcing portion 70. Thereby, the time-dependent deformation | transformation of the 1st top plate 40 can be suppressed with a simple structure, without providing the member for reinforcement separately.

  The reinforcement part 70 of this embodiment is demonstrated in detail. The reinforcing portion 70 is disposed in the vicinity of the hanging piece 30 from the viewpoint of suppressing the bending of the first top plate 40 due to the concentrated load on the root portion 38 of the hanging piece 30. In particular, in the present embodiment, the reinforcing portion 70 is attached to the hanging piece 30, and the weight of the package 10 is substantially reduced from the root portion 38 of the hanging piece 30 without going through the first top plate 40. 70. In the package 10 of the present embodiment, a frame structure including the suspended piece 30 and a plurality of reinforcing portions 70 disposed around the suspended piece 30 is concentrated and loaded on the boundary between the suspended piece 30 and the first top plate 40. The reaction force of the own weight of the package 10 is transmitted to the peripheral surface 60 or the second top plate 50.

  In this embodiment, the concentrated load on the suspension piece 30 is illustrated as being distributed and transmitted to the second top plate 50, but the first top plate 40 and the peripheral surface 60 are connected by the reinforcing portion 70. Thus, a load may be transmitted from the suspended piece 30 to the peripheral surface 60. Moreover, in this embodiment, although the 2nd top plate 50 is arrange | positioned above the 1st top plate 40, the structure which the reinforcement part 70 pushes up the 2nd top plate 50 at the time of suspension of the package 10 is illustrated. The present invention is not limited to this. When the first top plate 40 connected to the suspension piece 30 is disposed above the second top plate 50, a rib structure may be provided on the lower surface of the first top plate 40 as the reinforcing portion 70. . In this case, the rib structure on the lower surface of the first top plate 40 may be connected to the second top plate 50 facing the lower side of the first top plate 40 or to the peripheral surface 60. Thereby, the concentrated load applied to the suspension piece 30 when the package 10 is suspended can be distributed to the second top plate 50 or the peripheral surface 60.

  As shown in FIG. 3 (a) and FIG. 3 (b), which is an enlarged view thereof, in the present embodiment, the hanging piece 30 is formed on the hanging piece 30 so as to detachably engage the reinforcing portion 70. ing. For explanation, in FIG. 3B, the second top plate 50 is indicated by a broken line. The latch portion 32 is a recess formed in a cutout on both sides in the width direction of the base portion 38 of the hanging piece 30. The height dimension of the latching part 32 is equal to the dimension of the band width of the band-shaped reinforcing part 70 (end edge part 73). In other words, the upper end of the latching portion 32 substantially coincides with the height position of the second top plate 50. Then, by bringing the tip of the flap 72 bent from the side surfaces 63 and 64 into contact with the root portion 38, the end edge portion 73 is hooked to the hook portion 32, and the upper edge of the end edge portion 73 is the second top. It contacts the lower surface of the plate 50.

  Furthermore, the latching part 32 has an acute angle return part 34 that regulates the detachment of the latched reinforcing part 70. The return portion 34 is N-shaped, in other words, the internal height of the latching portion 32 is larger than the entrance height. Here, that the return portion 34 has an acute angle means that the angle formed by the side edge 31 in the width direction of the hanging piece 30 and the upper edge 33 of the hooking portion 32 formed on the side edge 31 is less than 90 degrees. It means that. Since the return portion 34 is formed on the upper portion of the hook portion 32, the end edge portion 73 hooked on the hook portion 32 is restricted from being detached. For this reason, the assembly of the package 10 is easy, and the reinforcing effect of the first top plate 40 by the reinforcing portion 70 (end edge portion 73) is stabilized.

  As shown in FIGS. 1B and 3, the flap 72 is bent obliquely downward from the upper ends of the side surfaces 63 and 64 with which the second top plate 50 abuts toward the root portion 38 of the suspension piece 30. Yes. The flaps 72 excluding the reinforcing portion 70 (end edge portion 73) correspond to diagonal surfaces of the rectangular parallelepiped space RS (see FIG. 3A) on both sides in the width direction of the hanging piece 30 in the upper hollow structure HT.

  That is, the flap 72 constitutes a diagonal surface of a hollow structure (cuboid space RS) surrounded by the first top plate 40, the second top plate 50, the peripheral surface 60 and the hanging piece 30. Since such a flap 72 has a bracing structure that prevents shear deformation of the rectangular parallelepiped space RS located on both sides of the hanging piece 30, bending deformation of the first top plate 40 is suppressed as a whole.

  The length of the flap 72 excluding the end edge portion 73 is equal to the diagonal length of the rectangular parallelepiped space RS, and is longer than the length from the other peripheral surface (side surfaces 63 and 64) of the first top plate 40 to the latching portion 32. Is also big. For this reason, the lower end of the edge part 73 latched by the latching part 32 does not detach | leave from the root part 38 of the suspension piece 30 by the rigidity of the flap 72 in the surface direction. That is, the flap 72 has a bracing structure that prevents shear deformation of the rectangular parallelepiped space RS, and also functions as a stopper that prevents the end edge portion 73 from being detached from the hook portion 32.

  As described above, the main body 20 of the present embodiment has a double top plate structure including the first top plate 40 and the second top plate 50. Each of the first top plate 40 and the second top plate 50 may be made of only one sheet material, or may be made of a plurality of sheet materials that are folded or stacked. In the present embodiment, as shown in FIG. 4, the first piece 40 a connected to the front surface 61 and the second piece 40 b connected to the first piece 40 a via the hanging piece 30 are overlapped to form the first. A top plate 40 is configured.

  In the sheet material 90 shown in FIG. 4, a side surface 63 is formed on one side of the front surface 61 in the circumferential direction, and a band-shaped joint portion 68 is formed on the other side. The joint portion 68 is a portion that bonds and joins the front surface 61 and the side surface 64. The first top plate 40 and the second top plate 50 are formed by further bending the main body 20 after the front surface 61 and the side surface 64 are bonded by the bonding portion 68 to form the peripheral surface 60 of the main body 20 in a cylindrical shape. . The first top plate 40 is disposed on the inner side (lower side) of the package 10, and the second top plate 50 is disposed on the outer side (upper side) (see FIGS. 1 to 3).

  The second top plate 50 connected to the rear surface 62 is formed with a first slit 52 and a second slit 53 that both extend in the width direction. The first slit 52 is a through hole for inserting the suspended piece 30 and the second slit 53 is for inserting the folding piece 65. A strip-shaped insertion piece 54 extending in the width direction is formed on the second top plate 50, and a second slit 53 is formed at a boundary portion between the insertion piece 54 and the second top plate 50. .

  5 and 6 are perspective views showing the processing steps of the package 10. In these figures, the folding line is indicated by a thin line.

  In the package 10 of the present embodiment, the first piece 40a and the second piece 40a are folded by folding the suspension piece 30 in two from the state in which the peripheral surface 60 of the sheet material 90 is bent and connected in a cylindrical shape (see FIG. 5). The first top plate 40 is formed by overlapping the pieces 40b (see FIG. 6). Further, after the accommodation P is accommodated in the accommodation space V (see FIG. 2), the first top plate 40 and the flap 72 are sequentially bent inward to obtain the state of FIG. Finally, the second top plate 50 is bent so that the suspended piece 30 protrudes from the first slit 52, and the folding piece 65 is inserted into the second slit 53 to lock the second top plate 50.

  With respect to the bottom of the main body 20, the first bottom plate 81 connected to the front surface 61 was twice folded, formed into a shallow dish shape, fitted into the lower end opening of the main body 20, and connected to the rear surface 62. The first bottom plate 81 is closed by the second bottom plate 82.

  FIG. 7 is a cross-sectional view showing the lower structure of the package 10. In the package 10 of the present embodiment, a first bottom plate 81 and a second bottom plate 82 that are spaced apart from each other are provided on the bottom 24 of the main body 20. That is, the package 10 of this embodiment includes a lower hollow structure HB surrounded by the first bottom plate 81, the second bottom plate 82, and the side surfaces 63 and 64. Thereby, the drop impact of the package 10 is absorbed by the lower hollow structure HB.

  As shown in FIGS. 4 and 7, the first bottom plate 81 is formed to extend to the lower part of the front surface 61. The second bottom plate 82 is formed to extend below the rear surface 62. The first bottom plate 81 is folded back into a band shape at the base end side and the distal end side in the thickness direction, bent into a concave shape, and folded inside the main body 20. The second bottom plate 82 has an insertion piece 84 formed in a band shape at the tip, and closes the lower end opening of the main body 20.

  The accommodation P accommodated in the accommodation space V is supported by the first bottom plate 81 inside the suspended package 10. Note that the lower hollow structure HB between the first bottom plate 81 and the second bottom plate 82 can also be used as a storage space for accessories or instructions of the storage item P.

Various modifications are allowed for this embodiment.
As shown in FIGS. 1B and 3, the reinforcing portion 70 of the present embodiment is an end edge portion 73 in which the tip of the flap 72 is folded back at a substantially right angle, but the present invention is not limited to this. The position and shape of the reinforcing portion 70 can be various. As an example, the reinforcing piece 70 may be formed by bending the hanging piece 30, the first top board 40 or the second top board 50 into a convex shape. Further, the reinforcing portion 70 may be formed by bending a bent piece cut into the peripheral surface 60 (the front surface 61, the rear surface 62, or the side surfaces 63 and 64) like the folded piece 65. In any case, the reinforcing portion 70 is provided between the hanging piece 30 and the second top plate 50 or between the hanging piece 30 and the peripheral surface 60, and the in-plane of the sheet material that is in the high strength direction in the reinforcing portion 70 The reinforcing portion 70 is arranged so that the direction intersects the first top plate 40, preferably orthogonally.

  FIG. 8 is a perspective view showing the reinforcing portion 70 according to the first modification of the present embodiment. The reinforcing portion 70 of this modification is configured by a triangular prism-shaped end edge portion 73 in which the tip of the flap 72 is valley-folded in two stages. Specifically, the standing surface 74 and the slope 75 are bent from the side close to the flap 72 to form a triangular prism together with the flap 72.

  A cut portion 76 having an arbitrary shape such as a semicircular arc is formed in the intermediate portion of the flap 72. By inserting and fixing the inclined surface 75 corresponding to the front end side of the flap 72 folded back in two stages into the cut portion 76, the end edge portion 73 maintains the shape of a triangular prism. At this time, the flap 72 is bent obliquely downward from the side surface 63 and the tip is in contact with the surface of the first top plate 40. The angle formed by the flap 72 and the upright surface 74 is an acute angle slightly smaller than a right angle, and specifically coincides with the remainder of the angle at which the flap 72 is inclined downward from the side surface 63. Thereby, the standing surface 74 stands upright with respect to the first top plate 40. In this state, the standing surface 74 is hooked on the hooking portion 32 (see FIG. 3) of the hanging piece 30 and fixed to the hanging piece 30.

  According to this modification, the reinforcing part 70 (end edge part 73) is not a plane of sheet material but a triangular prism shape, so that the reinforcing effect of the first top plate 40 is further enhanced. Specifically, the falling and twisting of the edge portion 73 due to the weight of the package 10 concentratedly loaded on the hanging piece 30 are preferably suppressed in the present modification.

  FIG. 9 is a perspective view showing a lower structure of the package 10 according to the second modification. FIG. 10 is a plan development view of the package 10 according to the second modification.

  The package 10 according to the second modification is characterized in that a bottom plate reinforcing portion 86 formed by bending a part of the main body 20 is provided in a gap portion between the first bottom plate 81 and the second bottom plate 82.

  Specifically, the main body 20 of the present modification has a rib portion 87 formed by bending the first bottom plate 81 inside the lower hollow structure HB sandwiched between the first bottom plate 81 and the second bottom plate 82. Yes. The bottom plate reinforcing portion 86 includes a rib portion 87, a lower flap 78, and a folded portion 79.

  The rib portion 87 is a reinforcing structure in which a part of the first bottom plate 81 is bent and formed into a mountain fold and a valley fold, and is erected at a substantially central portion in the thickness direction of the first bottom plate 81. The rib portion 87 is formed such that the center and both ends in the width direction are high, and the middle thereof is downwardly inclined and low. A central convex portion 88 is formed at the center of the rib portion 87 in the width direction. The height dimension of the central protrusion 88 is equal to the facing distance between the first bottom plate 81 and the second bottom plate 82. Thereby, when the lower end of the main body 20 is closed by the second bottom plate 82, the central convex portion 88 of the rib portion 87 standing from the first bottom plate 81 supports the center of the second bottom plate 82. For this reason, compression deformation of the lower hollow structure HB of the main body 20 is suppressed by the bottom plate reinforcing portion 86 (center convex portion 88).

  Inclined portions 89 are formed on both sides of the central convex portion 88, respectively. On the other hand, lower flaps 78 are formed to extend below the side surfaces 63 and 64, respectively. At the tip of the lower flap 78, a belt-like folded portion 79 is bent and formed into a valley fold. When the lower flap 78 is folded inside the main body 20 from the side surfaces 63 and 64, the lower flap 78 and the folded portion 79 are fitted into the inclined portion 89 of the rib portion 87. At this time, the end edge 79 a of the folded portion 79 coincides with the height of the upper edge 88 a of the central convex portion 88 of the rib portion 87. For this reason, the pair of folded portions 79 extending in the thickness direction and the central convex portion 88 of the rib portion 87 extending in the width direction constitute an H-shaped bottom plate reinforcing portion 86. Since the first bottom plate 81 and the second bottom plate 82 are reinforced in a planar shape by the H-shaped bottom plate reinforcing portion 86, damage to the contents P due to a drop impact at the bottom portion of the main body 20 is suitably prevented.

  In the package 10 of this modification, a folding piece 66 for locking the second bottom plate 82 is formed in the lower part of the front surface 61 in addition to the folding piece 65 (see FIG. 1) for locking the second top plate 50. Yes. By opening the folding piece 66 through the lower slit 85 formed in the insertion piece 84 of the second bottom plate 82, the opening of the second bottom plate 82 is restricted. This prevents the second bottom plate 82 from being opened by the weight of the contents P. Further, since the lower hollow structure HB is prevented from being opened when the package 10 is subjected to a drop impact, the bottom reinforcing effect by the bottom plate reinforcing portion 86 can be suitably obtained.
