Description

  The present invention relates to a box-shaped packaging case for storing and packaging a product in a box-shaped container.

  As a box with a lid for packaging that is assembled and used in a flat folded state, conventionally, a bevel mountain fold line from the front corner of the bottom plate to the edge of the front plate, and the edge of the side plate from the rear corner of the bottom plate And a slope fold line extending from the front corner of the top plate to the edge of the lid front plate is disclosed (for example, see Patent Document 1). In this box with a lid, in the folded state, the front plate, both side plates and the front plate of the lid are folded along the oblique mountain fold line, oblique valley fold line and oblique mountain fold line, respectively, so that the bottom plate and the rear plate overlap. Folded. By simply raising the rear plate from the bottom plate and extending the folding of the front plate, both side plates, the front plate of the lid or the lid side plate, it is possible to quickly squeeze from a flat folded state without the need to fold or hold the connecting piece. It can be assembled.

Japanese Patent Laid-Open No. 2004-1778

  The box with a lid is easy to assemble because it does not require folding, holding, etc. at the time of assembly. In addition, a complicated folding work is required, and a folded product cannot be mechanically produced, which does not lead to an improvement in folding workability. Moreover, since the sides for folding are greatly overlapped, a relatively large side plate is required, and it cannot be said that productivity is good. Furthermore, since the side plates on both the left and right sides need to be lifted, a certain number of man-hours are still required in the assembly operation.

  Therefore, the present invention aims to provide a box-type packaging case that is easier to assemble, improves the workability of folding, and does not require a relatively large part for folding, and has good productivity. To do.

The present invention employs the following means (1) to (5) in order to solve the above problems.
(1) In the box-shaped packaging case of the present invention, the front plate 10 to the top plate 2, the back plate 6, and the bottom plate 3 are connected in a loop shape, and the side plates 12 and 14 from the front plate 10 or the back plate 6 are connected. Folded in a double sheet, folded at the connecting edge between the loop-shaped front plate 10 and either the top plate 2 or the bottom plate 3 and connected to the left and right sides. A box-shaped packaging case that can be assembled into a box state from the bottom plate 3 or the top plate 2 folded to the front plate 10 side in the folded state to at least one of the left and right outer sides. And the tip of the connecting arm 4 is bonded to the left or right side plate 12 or 14 connected to the front plate 10 or the back plate 6 in the folded state. To do.

  In the packaging case, when the folded back plate 6 and the front plate 10 are separated from each other and the loop-shaped portion is assembled in an annular shape, the side plate connected to the connecting arm 4 is linked to one loop-shaped annular shape. Get up to close your mouth. Since the side plate rises automatically, the assembling work from the folded state to the box state becomes easy. At the same time, the other loop-shaped annular opening is greatly opened to facilitate the product stuffing operation and the product removal operation. In particular, in the vertical packaging container in which the vertical width of the back plate 6 and the front plate 10 is longer than the horizontal width, the product can be packed / taken out from the side opening larger than the top plate or the bottom plate, and the workability is good. It becomes.

  (2) Alternatively, the box-type packaging case of the present invention is such that the front plate 10 to the left side plate 14, the back plate 6 and the right side plate 12 are connected in a loop, and the front plate 10 or the back plate 6 to the top plate 2 and the bottom. A box from a folded state in which the face plates 3 are connected to each other upward and downward, folded at the connecting side between the loop-shaped front plate 10 and the left and right side plates 12/14 and stacked in a double sheet shape. A box-shaped packaging case that can be assembled into a state, wherein the connecting arm 4 extends from at least one of the left and right side plates 12/14 folded to the front plate 10 side in the folded state to at least one of the upper and lower sides. The front portion of the connecting arm 4 is bonded to either the top plate 2 or the bottom plate 3 connected to the front plate 10 or the back plate 6 in the folded state. This embodiment corresponds to another embodiment described later.

  (3) In the box state of the box-shaped packaging case according to any one of (1) and (2), it is preferable to have a vertical partial pyramid shape whose bottom surface is larger than the top surface. Furthermore, it is preferable that at least two or more of the face plates are composed of a transparent or translucent resin sheet. If it is such, since the shape of the goods accommodated will appear in the transparent box-shaped case of the partial pyramid shape with a stable feeling, it is excellent in the display effect. Further, the articulated arm 4 can be formed of small pieces that do not take up a large area, so that the appearance is good without losing transparency.

  (4) In the folded state, the connecting arm 4 of the box-type packaging case according to the above (1) to (3) is positioned in one direction on the side of the face plate to be attached (for example, the back on the side of the bottom plate 3). The position close to the face plate 6 is set as the attachment base 4R, and the direction from the attachment base 4R to the position closer to the other direction of the side than the perpendicular direction line of the side (for example, the normal direction of the side of the bottom plate 3 is used as a reference) As shown, the lead rule 4C is obliquely extended, and the lead ruler 4C that can be reversely folded is applied to the tip of the lead plate 4C. It is preferable to adhere to 12/14. In this case, the face plate (for example, the side face plate 14) to which the connecting arm 4 that extends obliquely is reliably lifted at the position near the center of the face during assembly, and the assembly work becomes easier. . Further, the connecting arm 4 is formed as a small piece that does not use an extra area by extending obliquely backward rather than perpendicular to the side of the mounting base 4R. As a result, the size of the original plate can be reduced and the production can be efficiently performed, and the connecting arm 4 is hardly noticeable even after the box is formed.

  (5) In the folded state of the box-shaped packaging case according to any one of (1) to (4), the front plate 10 or the back plate 6 is folded at a rounding side 56L for forming a loop shape, and is in a box state In this case, it is preferable that one box-shaped surface is formed by being bent at a position deviated from the discarded side 56L. For example, in the embodiment described later, in the folded state, it is folded at the folding side 56L and looped, but in the box state, it is folded at the rear folding side 25L slightly parallel to the folding side 56L and is A face plate 2 is formed. By shifting the rear folding side 25L of the top plate 2 upward from the rounding side 56L, the back portion of the box shape becomes larger. In addition, a fold crease by the discarded fold side 56L is once attached before forming the box state, so that a box-shaped case having the discarded fold portion 5 and having higher rigidity is formed.

  The box-shaped packaging case of the present invention employs the above-described means, and the assembling work becomes easier because the connecting arm 4 automatically pulls up the single-faced plate in the loop-shaped annular mouth by the separation of the loop-shaped portion. Further, since the loop-shaped portion and the connecting arm 4 can be formed in a planar manner only by folding and bonding, the folding workability is improved, for example, the laminating process is possible with a sack machine. Moreover, a relatively large part for turning back is not required, and a box-type packaging case with good productivity is obtained.

Each of the box-type packaging cases of the present invention comprises a back plate 6, a front plate 10, a top plate 2 and a bottom plate 3, and one or more side plates 11, 12, 14 in total to the left and right. It consists of a resin sheet in which two or more face plates are integrally connected. This resinous sheet is folded between the face plates and is surface-bonded only at two locations of the first and second bonding regions A1 and A2, and is continuously produced in the folded state shown in the left diagram of FIG. This folded resin sheet is folded at the connecting side between the face plates, abuts the sides, and is partially inserted and connected to form a vertical partial polygonal pyramid shape as shown in FIG. Configured into a box. In the embodiment, a loop-like plate group in which four face plates including a front plate 10 and a back plate 6 are connected in a prismatic shape, and a left and right side connected from one of the face plates constituting the plate group to the left and right sides. It consists of face plates 11, 12, and 14.

(Before folding)
Each face plate is a sheet, and a large original plate including each plate surface is cut into a predetermined outer shape by a cutting process, and a crease is provided at a necessary folding side including a side of each face plate by a processing process. Thus, the state before folding shown in FIG. The cutting process is a process of cutting an outer shape from a large original plate, and the processing process is a process of creating a folded rule or a lead rule. A large original plate is cut into a predetermined outer shape shown in FIG. 1 by the cutting process, and a crease rule, a loop rule, and a cut are given by the processing process.

  Specifically, in the state before folding, the first side plate 12, the bottom plate 3, and the left side plate 14 of the top plate 2 and the right side plate are respectively extended from the four sides of the vertically long trapezoidal front plate 10 to the upper, lower, left and right sides. Articulated. In addition, it is desirable that at least a part of each face plate has transparency. For example, at least the front plate 10 and the left and right side plates 11, 12, and 14 are made of a transparent or translucent resin sheet.

  Further, an inverted vertical trapezoidal back plate 6 is connected to the upper side of the top plate 2, and an upper end portion of the back plate 6 is attached to the first bonding area A 1 side of the bottom plate 3 to form a loop configuration. The attachment piece 6F is extended. A notch 6C cut in a substantially U-shape is formed at the affixed side or in the center of the back plate 6 in the height direction. The bottom plate 3 has a polygonal shape, the top plate 2 has a smaller area than the bottom plate 3, and the side plates 11, 12, and 14 are formed longer in the longitudinal direction than the maximum diagonal length of the bottom plate 3. The As a result, the box shape is a vertical partial square pyramid box.

  The left and right side plates 11, 12, 14 include a left side plate 14 laterally connected from one side of the front plate 10 and a right side plate (11, 12) laterally connected from the other side of the front plate 10. . Of the left side plate 14 and the right side plate (11, 12), the first side plate 12 and the left side plate 14 both have the same vertical trapezoidal shape, and flap pieces 121F and 141F are extended from the upper side, respectively. A flap piece 14F is extended from the side edge of the left side plate 14 to the outer side, and a notch 14C for inserting the insertion portion 11I of the right side plate is inserted in the longitudinal center on the side edge. Is provided. In the plane of the flap piece 14F, an insertion portion 14I is formed by cutting over a substantially half side length provided in the vertical direction at a substantially central position in the height direction.

  The right side plate includes a first side plate 12 laterally connected to the front plate 10 and a second side plate 11 laterally connected to the first side plate 12. Further, an insertion piece 11I extending from the side edge of the second side plate 12 to the outer side and extending over the half side length of the side edge is extended, and the second side plate is located at the center in the length direction on the side edge. A cut piece 11C for inserting and releasing 11 is provided.

(Folded state)
From the state before folding in FIG. 1 through the cutting step and the processing step, through the first folding step, the adhesive application step, the second folding step, and the pressing step, The folded state is formed by folding and bonding at a predetermined bonding region. In the embodiment, as shown in FIG. 2, the lower side of the front plate 10 and the upper side of the back plate 6 or the upper side of the front plate 10 and the lower side of the back plate 6 are bent, so The front-side two-sided plate connected to the front plate 10 and the back-side two-sided plate connected to the back plate 6 are in a folded state.

  Specifically, in the first folding step, the scraping side 56L at the top of the back plate 6 is folded in a mountain fold, and the top plate 2 is overlapped with the back plate 6 in contact with each other (FIG. 2 (b)). Adhesive is applied to the loop adhesive region A1 on the bottom plate 3 and the arm adhesive region A2 on the left side plate 14 by the adhesive application step (FIG. 2B), and then the lower side of the front plate 10 is valleyd by the second folding step. The bottom plate 3 is folded by folding and overlapped with the front plate 10 in contact with the back surfaces (FIG. 2 (c)). After that, the sheets folded and overlapped by the pressing process are pressed into a flat shape to complete the bonding in a predetermined bonding region (FIG. 2C).

(First folding process)
The discarded side 56L in the first folding step is a position shifted to the back plate 6 side from the rear folded side 25L of the top plate 2 and is folded at the rear folded side 25L when assembled into a box state. A large back plate 6 is secured. The discarded side 56L is a bent side for bonding to form a loop shape from the original plate shape, and the discarded folded part 5 formed between the discarded side 56L and the rear folded side 25L, By being formed slightly obliquely from the back plate 6, it is possible to form a highly rigid box state.

  In the first folding step, the back plate 6 is folded back at the folding side 56L, so that the flap piece 6F at the tip of the back plate 6 is inverted and disposed at a predetermined position on the front plate 10 that becomes the loop adhesion region A1. . The adhesive was applied onto the loop adhesive region A1 by the subsequent adhesive application step, and the bottom plate 3 folded back onto the loop adhesive region A1 was inverted and overlapped at the subsequent second folding step. It becomes a state.

(Adhesive application process)
The adhesive application process is a process in which hot-melt adhesive is spray-applied to a predetermined adhesive region, the first and second folding processes are processes in which they are folded in a direction crossing the feed direction, and the pressing process is performed from above. This is a pressing surface bonding process. Any of these can be continuously produced as a compact sheet-like material that is not bulky in the height direction by a mechanical process during conveyor conveyance by a sack machine or a press roller.

  The predetermined adhesion region in the adhesive application step is the flap piece 6F / at the front of the back plate 6 or the front plate 10 in the folded state in which the loop-shaped plate group including the front plate 10 and the back plate 6 is folded. Two areas of the loop adhesion area A1 where 10F overlaps the surface of the bottom plate 3 or the top plate 2 and the arm adhesion area A2 where the adhesion surface 4f of the tip of the connecting arm 4 overlaps the plane of the side plate 12/14 Say.

  In the embodiment, the loop adhesion region A1 is a horizontally long oval region along the lower side of the bottom plate 3, and the flap piece 6F and the bottom plate 3 at the front portion of the back plate 6 bent at the folding side 56L. Are provided in the overlapping region. Further, in the embodiment, the arm adhesion area A2 is a perfect circular area provided in the vicinity of the lower side of the left side plate 14, and is connected to the bottom plate 3 bent at the lower side of the front plate 10 so as to move upside down. It is provided in a region where the adhesive surface 4f at the front portion of the arm 4 and the left side plate 14 overlap.

  In the embodiment, the hot melt type adhesive is applied by spraying, but other types of adhesives such as a room temperature curing type or an ultraviolet curing type may be used, and the adhesive may be used as a roller. It may be applied by.

(Assembled)
The box-shaped packaging case of the present invention is assembled into a box state by folding back each connecting side of the face plates from the folded state. In assembling, first, as shown in FIG. 3, when the back plate and the front plate folded to the side are separated and the loop-like portion is assembled in an annular shape, the left side plate 14 on the side connected to the connecting arm interlocks. Then, it gets up so as to block one loop-shaped annular mouth (the annular mouth on the left side in FIG. 3). Since the left side plate 14 is automatically raised by the connecting arm 4, the assembly work from the folded state to the box state is facilitated. At the same time, the other loop-shaped annular opening is greatly opened to facilitate the product stuffing operation and the product removal operation. Especially in the vertical packaging container where the vertical width of the back plate and the front plate is longer than the horizontal width, as shown in FIG. Workability will be good.

  Next, as shown in FIG. 4, the loop-shaped face plates stacked in a folded state are separated from each other into an annular shape, so that one side of the loop-shaped plate group serves as an internal accommodation port, and the one side One side plate or one side plate group connected to the outside becomes a lid plate that closes the internal accommodation opening (FIG. 4). Further, the other side plate connected to the other side opposite to the internal accommodation port is connected to the bottom plate 3 by the connecting arm 4. As another embodiment, the connecting arm 4 may be connected to the top plate 2.

  As shown in FIG. 5, in the box state, the loop-shaped back plate 6 and the second side plate 12 on the front side of the front right side plate overlap to form a hexahedron. At this time, the left side plate 14 can be fixed to the back plate 6 side by pinching the insertion portion 14I and inserting it into the cut 6C of the back plate 6. Further, by inserting the insertion portion 11I of the second side plate 11 of the right side plate into the cut 14C of the left side plate 14, the second side plate 11 of the right side plate can be reliably fixed to the left side plate 14 side.

(Connecting arm 4)
The articulating arm 4 is formed of a rectangular plate-like member extending in a predetermined direction, and both ends thereof are laterally connected to the front plate 10 in the same manner as either the bottom plate 3 or the top plate 2 laterally connected to the front plate 10. The left and right side plates 12 and 14 are connected to each other. The connecting arm 4 is provided on either the top plate 2 or the bottom plate 3. However, the provided top plate 2 or bottom plate 3 may be extended only from one side to one side. Further, it may be symmetrically extended outward from both sides. As shown in FIG. 1, the extending direction of the connecting arm 4 in the cut state before the folded state is an oblique direction near the adjacent side of the adjacent side plate 12 or 14.

  The connecting method of both ends of the connecting arm 4 may be any one of pasting, heat welding, adhesive fixing by insertion, or integral molding cut out from the original plate. The attachment base portion 4R of the connecting arm 4 in the embodiment is integrally formed in the cut state shown in FIG. 1, and the tip portion serves as the bonding surface 4f and is in the plane of the left side plate 14 that is overlapped in the folded state. It is adhered to the overlapping part. The overlapping portion in the surface of the side plate is used as an arm bonding region A2, and an adhesive is applied in advance to the arm bonding region A2 on the side plate 12/14 before folding.

  The connecting arm 4 of the embodiment is inclined by about 30 to 45 degrees from the mounting base 4R toward the left side plate 14 with respect to the perpendicular direction of the side, with the position on the side of the bottom plate 3 being the mounting base 4R. Stretch linearly in an oblique direction. The attachment base of the connecting arm 4 is connected from one side of the bottom plate 3 and is assembled in the mountain direction with the connecting side as a connecting boundary when assembled. However, the connecting arm 4 is not limited to the left side plate 14 side, and may be extended to the right side plate 12 side. The attachment base 4R of the connecting arm 4 is not limited to the side of the bottom plate 3 but may be the side of the top plate 2.

  The leading portion of the connecting arm 4 is provided with a lead rule 4C that divides a rectangular bonding surface on the leading side, and the bonding surface 4f is formed on the leading portion. The adhesive surface 4f is attached to the arm adhesive region A2 in the surface of the side plate 14 by a hot melt adhesive. At the time of assembly, the lead ruled line 4C is used as a folding side and the sheet is folded back in the valley folding direction. Further, the tip portion of the connecting arm 4 is formed at a position shifted upward or downward from the mounting position of the base portion instead of just in the lateral direction. The extending direction of the connecting arm 4 is relative to the bending direction and the top plate 2 or the bottom. The direction is oblique with respect to the connecting side direction of the face plate 3. Thus, the surfaces of the side plates 12 and 14 attached at the time of assembly are automatically pulled up. In addition, when the loop-shaped part is in a folded state, the adhesive surface 4F is attached to the side plate 14 with the adhesive surface 4F as the bottom surface, so that the machine can be attached by a sack machine, and the rigidity of the box is reduced by reverse folding when assembled. Can be secured (FIGS. 4 and 5).

Instead of the above embodiment, the back plate 6 may be connected in a loop shape from the front plate 10 via both side plates (not shown). In this case, the top plate 2 and the side plate are connected in the vertical direction from either the back plate 6 or the front plate 10, and the connecting arm 4 is connected to at least one of the upper and lower sides from either the left or right side plate 12 or 14. The front end of the connecting arm 4 is bonded to either the top plate 2 or the bottom plate 3 in a folded state in which the loop-shaped back plate 6 and the front plate 10 are folded. In this case, the second side plate 11 does not exist. When the front plate 10, the back plate 6, and the left and right side plates 12, 14 are connected in a loop shape and the connecting arm 4 is provided on the bottom plate 3, the top plate 2 is an upper lid in a box state. It becomes an open container.

  In addition, the present invention is not limited to the above-described embodiments, and various configurations, shape changes, element extraction, combination changes or additions can be made without departing from the spirit of the present invention. For example, the shape of the container in a box state is not limited to the above-described vertical partial quadrangular pyramid, but may be a pentagonal pyramid, a hexagonal pyramid, or a substantially conical shape, and may be a horizontally long shape instead of a vertically long shape. In addition, for example, a partition may be extended from each side so that a commodity to be contained does not move in the container, and the product may be set up in the container space or crossed.
