Description

  The present invention relates to a packaging box for storing products such as cosmetics.

  In order to prevent damage during transportation, a packaging box for storing a product that is easily damaged, such as a cosmetic bottle, is often provided with a product support member such as an impact absorbing material inside the packaging box. For example, an impact absorbing material (supporting member) shown in Patent Document 1 below is a three-dimensional assembly of a notch or the like in which a product to be stored just fits in a cardboard. The assembled support member is placed in a packaging box to hold the stored product without rattling.

JP-A-7-291355

  The supporting member shown in Patent Document 1 is a separate member from the packaging box main body, and the supporting member must be assembled and then placed in the packaging box to store the product, which is complicated. In addition, if this support member is assembled in advance before the operation of storing the product, the complexity is slightly reduced, but a place for temporarily stocking the assembled bulky support member must be secured. , Often inconvenient.

  Then, this invention makes it a subject to perform the accommodation operation | work of the goods to the packaging box provided with the supporting member simply.

  In order to solve the above-described problems, the present invention does not need to perform a step of integrally forming the support member and the packaging box body and putting the support member assembled in a three-dimensional manner into the packaging box when the product is stored. I did it. Furthermore, before the product is stored, the packaging box and the support member are folded to save space, and when the packaging box is three-dimensionally assembled in the storing operation, the support member is simultaneously three-dimensionally assembled. So that the efficiency of this storage operation can be greatly improved.

As a configuration of the present invention, the sides on both sides of the front plate are connected to the sides on both sides of the back plate, and the both sides are brought close to each other so that the front plate and the back plate are expanded outward. In a packaging box in which a space is formed between the two plates, and a product is stored in the two plates, projecting pieces are connected to the lower ends of the front plate and the back plate via crease lines, respectively. The projecting piece is a folded piece at the center in the lateral direction, and a supporting piece and an upright piece are sequentially arranged on the left and right sides of the folded piece via a crease line, respectively, and the supporting piece and the folded piece are provided. The two crease lines that respectively define the piece and the standing piece intersect on the crease line between the front plate, the back plate, and the protruding piece, and the protruding piece of one of the protruding pieces A connecting piece is connected to the upright piece via a crease line, In this folded state, the connecting piece and the upright piece formed on the protruding piece facing the protruding piece are pasted together along the inner surface side of the front plate and the back plate. In addition, when the product is stored, the folding piece is maintained in a state along the inner surface side, and the standing piece rises in the space, and the support piece is connected to the standing piece along with the standing. Also, the stored product is supported by the two support pieces, each standing on the space and separated from the adjacent support piece by the folding piece, on each of the front plate side and the back plate side .

  Further, the support piece is provided with a folded piece and an upright piece arranged adjacent to each other. The folded piece keeps the state along the front plate or the back plate in either the folded state or the assembled state of the packaging box. On the other hand, the upright piece maintains a state along the front plate or the like in the folded state of the packaging box. However, the upright piece stands up from the front plate or the like in the assembled state of the packaging box. This is because when the sides of the front plate and the back plate are brought close to each other, the front plate and the back plate are curved outward (inflated outward), and a space is formed between both plates. This is because the upright pieces connected by the connecting pieces attract each other so as to straddle the space.

  When the upright piece rises in this way, the support piece connected to the upright piece also tries to stand up. However, the side of the support piece that is connected to the folded piece is restrained by the folded piece and cannot stand up. For this reason, this support piece stands up diagonally upward from the lower end of the front plate or the back plate.

  As described above, the support piece standing obliquely upward functions as a bottom plate that comes into contact with the bottom surface of the product to support the product and prevents the product from falling to the lower side of the packaging box. At the same time, when a downward impact is applied to the product, the support piece bends downward and also functions as a support member that reduces the impact.

  The folding piece, the support piece, and the upright piece constituting the protruding piece are stored in a folded state in the box when the packaging box is folded, and are compact and excellent in storability. Moreover, since the assembly of the support member (standing up of the support piece) is performed simultaneously with the assembly of the packaging box, the product can be stored smoothly.

  Moreover, in the said structure, it is preferable to form the curved part which follows the bottom part shape of the said goods in the support end of the said goods of the said support piece.

  The shape of the curved portion is appropriately determined according to the shape of the bottom of the product to be stored. For example, when the bottom center has a convex shape upward compared to the outer peripheral portion, the upright portion of the support piece is rounded upward near the front end portion so that the front end portion just follows the vicinity of the bottom center portion. In this case, the bottom of the product can be stably supported by this support piece.

  Moreover, in each said structure, it is preferable to form the protrusion part contact | abutted to the said stored goods in the said standing piece.

  For example, the protrusions abut against the side surfaces of the product to suppress rattling, and the product can be prevented from being biased in the packaging box.

  Further, in each of the above configurations, a lid plate having the same shape as the upper opening shape when a product is stored in the box body is connected to the upper end of at least one of the front plate or the back plate via a crease line, It is preferable to form an engaging portion with which the product abuts on the lid plate.

  This latching part can suppress the shakiness of the upper part of goods, and can stabilize the support state of goods by a support member by this. For this reason, the damage prevention function of goods further increases.

  In this invention, the support member and the packaging box main body for preventing breakage of the commodity are integrally configured. Before the product is stored, the packaging box and the support member are in a folded state, and space can be saved. On the other hand, in the storage operation, when the packaging box is assembled, the support member composed of the support pieces and the like are also three-dimensionally assembled at the same time, so that the efficiency of the product storage operation can be greatly improved.

  A perspective view of a first embodiment of the packaging box according to the present invention is shown in FIG. 1, and a developed view is shown in FIG. In this packaging box, the sides on both sides of the front plate 1 and the sides on both sides of the back plate 2 are connected to each other, the both sides are brought close to each other, and the front plate 1 and the back plate 2 are expanded outward. In this way, a space is formed between the plates 1 and 2, and the product P is stored in this space (see FIG. 1).

  The packaging box includes a front plate 1, a rear plate 2, projecting pieces 3 connected to lower ends of the front plate 1 and the rear plate 2 via a crease line f, and upper ends of the front plate 1 and the rear plate 2. And a cover plate 4 provided continuously through the crease line f. A connecting piece 5 is connected to the side of the front plate 1 via a crease line f. In addition, a window 6 is formed on the front plate 1 so that the product P stored in the packaging box can be seen from the window 6.

  The projecting piece 3 connected to the lower ends of the front plate 1 and the back plate 2 is formed with a folding piece 7 at the center in the lateral direction. The pieces 9 are arranged symmetrically through the crease line f. The two fold lines f and f that define the support piece 8, the folding piece 7 and the upright piece 9 intersect each other at the fold line f between the front plate 1 and the back plate 2 and the protruding piece 3. . Ruled lines m are respectively formed on the front plate 1 and the back plate 2 from the intersections of the crease lines f. When the ruled line m is formed, the front plate 1 and the back plate 2 can be easily bent along the ruled line m when assembling a packaging box, which will be described later. A connecting piece 10 is connected to the left and right ends of the protruding piece 3 connected to the lower end of the front plate 1 via a crease line f.

  The support end 8 a that contacts the product P of the support piece 8 has a curved shape, and the support end 8 a just follows the bottom of the product P so that the stored product P can be stably held. . The shape of the support end 8a is not limited to that shown in the figure, and it is preferable that the shape is appropriately changed according to the shape of the bottom of the product P.

  The lid plate 4 on the side of the back plate 2 is formed with a locking portion 11 so that the product P can be stably held by sandwiching the upper portion of the stored product P between the two locking portions 11, 11. I have to.

  The perspective view of the assembly process of this packaging box is shown to FIG. 3A-FIG. 3D. First, the protruding pieces 3 connected to the front plate 1 and the back plate 2 are folded back inside the packaging box (see FIG. 3A). Then, paste is applied to the shaded portion of the folded piece 7 of the folded back projecting piece, and the folded piece 7 is attached to the inner surfaces of the front plate 1 and the back plate 2 (see FIG. 3B).

  Next, paste is applied to the shaded portion of the connecting piece 5 provided continuously with the front plate 1, the front plate 1 is folded back to the back plate 2 side, and the connecting piece 5 is attached to the back plate 2. At the same time, the connecting piece 10 connected to one upright piece 9 is folded back, paste is applied also to the shaded portion of the connecting piece 10 and is attached to the other (opposing) upright piece 9 (see FIG. 3C). ). This completes the preparation before storing the product.

  In this pre-preparation stage packaging box, the support member composed of the folding piece 7, the support piece 8, and the upright piece 9 is folded inside the packaging box body, and is in a flat and compact state as a whole. (See FIG. 3D). For this reason, the folded packaging box can be accumulated and stored, and a large space is not required for this storage.

  When the packaging box body is assembled three-dimensionally, the support member is assembled three-dimensionally at the same time, and as shown in FIGS. 4 and 5, the product P can be stored in the packaging box in the assembled state. As shown in FIG. 6, the stored product P is stably held with its bottom contacting the support end 8 a of the support piece 8. Moreover, as shown in FIG. 7, the head is abutted so as to be sandwiched between the two locking portions 11, 11 and rattling is prevented, so that breakage during transportation or the like is prevented.

  The support member is assembled as follows. First, the both sides of the front plate 1 and the back plate 2 are brought close to each other, and the front plate 1 and the back plate 2 are curved so as to bulge outward, thereby separating the plates 1 and 2 from each other. Then, along with this separation, the upright pieces 9 of the projecting pieces 3 connected to the both plates 1 and 2 try to be separated from each other. However, since the opposing upright pieces 9 and 9 are connected to each other by the connecting piece 10 as described above, the free standing of the upright pieces 9 and 9 is prevented. For this reason, both standing pieces 9, 9 are gradually raised from both plates 1,2.

  On the other hand, the folded pieces 7 attached to the both plates 1 and 2 are maintained in a state along the both plates 1 and 2 when the packaging box body is assembled. For this reason, the support piece 8 connected to both the folding piece 7 and the upright piece 9 is along the both plates 1 and 2 on the one fold line f side, and the upright piece 9 on the other fold line f side. It will be triggered. That is, the support piece 8 stands up from the lower ends of both plates 1 and 2 so as to protrude upward and obliquely.

  When the product P is supported by the support piece 8 standing in the obliquely upward direction, when the impact in the vertical direction is applied to the product P, the support piece 8 is easily bent downward, so that the impact is effectively reduced. be able to. Further, since a gap is formed between the support pieces 8, the lot number or the like written on the bottom of the product P can be easily read through the gap.

  After storing the product P, the lid plate 4 connected to the upper ends of the front plate 1 and the back plate 2 is folded inward to complete the boxing operation of the product P.

  FIG. 8 is a development view of the second embodiment of the packaging box according to the present invention, and FIG. 9 is a perspective view thereof. This packaging box has substantially the same configuration as the packaging box shown in FIG. 1, but the shape of the support piece 8 is slightly different. The support piece 8 is configured so that the support ends 8a of the four support pieces 8 are arranged almost horizontally and in a quadrangular shape when the packaging box is three-dimensionally assembled. The shape of the support end 8a of the support piece 8 can be appropriately changed according to the shape of the bottom of the product P to be stored. Since there is a gap between the support pieces 8, the lot number or the like written on the bottom of the product P can be easily read through this gap, as in the packaging box shown in FIG.

  A protrusion 12 (see FIG. 8) is formed at the tip of the upright piece 9, and this protrusion 12 abuts the lower part of the stored product P. This contact prevents the product P from rattling and prevents damage during transportation.

FIG. 10 is a development view of an embodiment of a reference example for the packaging box according to the present invention, and FIG. In the first and second embodiments, a gap is provided between the support pieces 8 so that the bottom of the product P can be seen from the gap. However, as in this embodiment, no gap is provided. You can also. Comparing the developments of the second embodiment and the embodiment of the reference example , in the second embodiment, the angle between the support ends 8a of the support pieces 8 formed on the projecting piece 3 is about 160 degrees. On the other hand (see arrow θ1 in FIG. 8), in the embodiment of the reference example , the angle is about 100 degrees (see arrow θ2 in FIG. 10).

  Thus, when the angle formed by the support ends 8a is reduced, the support ends 8a and 8a can be brought into contact with each other when the packaging box is assembled (the gap is closed). The angle for closing the gap varies depending on the shape of the packaging box (the distance between the front plate 1 and the back plate 2 at the time of assembly, etc.), and thus is appropriately determined in the design stage.

  In each of the above embodiments, the window portion 6 is formed on the front plate 1, but the window portion 6 can be omitted if not necessary. Moreover, the latching | locking part 11 formed in the cover plate 4 and the projection part 12 formed in the standing piece 9 can be suitably added or abbreviate | omitted in any embodiment.
