Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an outer cardboard box that can be stacked at the time of transportation and storage, such as bagged goods such as bag confectionery or soap for refilling, and goods that are soft and cannot be self-supporting. The present invention relates to an outer corrugated cardboard box which is partially cut out so that the product can be exposed and displayed.

[0002]

[Prior art]

 The type of the cardboard box is specified in JIS-Z-1507. Among them, the general 0201 type cardboard box (formerly called A-1 type) has a ruled line and width parallel to the length direction on one cardboard sheet as shown in the development of FIG. In addition to the ruled lines parallel to the direction, a cutting line is further cut at the end of each ruled line in each width direction, and a pair of wide and narrow side plates are alternately provided, and the upper and lower edges of each pair of side plates are alternately connected. An outer flap and an inner flap at the top or bottom are connected to each other, and the above-mentioned side plates are joined to each other by a connecting margin. To assemble a corrugated cardboard sheet of this structure, fix the joining margin with an adhesive such as hot melt or stitching, spread the trunk, fold the inner flap at the bottom inside the box, and further fold the outer flap at the bottom inside. Then, the joint of the outer flap is closed with a tape or a hot melt to seal the bottom surface. The outer box is completed by inserting the contents from the top side, folding the top side flap in the same way as the bottom side, and sealing. As a result, the top and bottom of the box can be covered exactly.

[0003] The cardboard boxes sealed after the contents are put in the warehouse are stored in a stacked state. Even after shipment, they may be piled up in retail stores or stores. As a result, the lower stacked boxes in the stacked state may lose their commercial value due to the collapse of the boxes and the deformation of the contents. Thus, for example, boxes containing bagged goods, such as bag confectionery or refillable soap, can be made from strong base paper to make the boxes strong enough to withstand transportation, storage, or stacking during sales. The strength of the box was increased by incorporating a number of partition plates in a cross-girder shape. However, such a method is not preferable from the viewpoint of resource saving and is disadvantageous in terms of cost. In other words, the amount of base paper used increases, or the amount of virgin pulp added to improve the strength of base paper increases. Therefore, the box strength can be improved without increasing the amount of paper used, improving the strength of the material used, or changing the configuration of the base paper flute.In addition, the collapse of the box and the deformation of the contents can be suppressed when the boxes are stacked. There has been a demand for an outer cardboard box. In addition, many cardboard boxes for exterior use are dismantled at the distribution stage, but reducing the amount of packaging waste such as cardboard discarded at the distribution stage is of great concern. Furthermore, in order to improve the sales promotion effect by mass display at retail stores, cardboard boxes for exterior use that can be used effectively for display sales of products by cutting a part of the box to expose the product. It has been demanded.

Conventionally, bagged products such as bag confectionery or refilling soap, or products that themselves are soft and cannot be self-supporting, are housed in packaging boxes that can be stacked during transportation and storage. A packaging box with a pressure-resistant partition plate of Utility Model Registration No. 3064784 is known. However, since this packaging box required three steps of sticking the body, it could not be handled by a general box-making machine and would need to be modified. In addition, since the box body and the partition plate must be made of the same material and made into a one-piece structure, the cost of the material is increased, and in order to save resources, a base paper or a base paper flute structure with a weaker U.S. tsubo, which is less strong as a partition material, is used. There was a problem that even if you wanted to use the changed thin base paper, it could not be used. Furthermore, the conventional outer box could not be reused as a display box at retail stores.

[0005]

[Problems to be solved by the invention]

 In view of the above circumstances, the present invention seeks to obtain a cardboard box for exterior that maintains the strength of the box even when using base paper of inferior strength. We propose a corrugated cardboard box for exterior that can be displayed in large quantities in a state where products are exposed and the products can be piled up in an exposed state.

[0006]

[Means for Solving the Problems]

 In order to solve the above problem, the present invention has a pair of wide and narrow side plates alternately arranged in the lateral direction, and the upper and lower flaps of the pair of side plates are provided with an outer flap and an inner flap. An outer flap and an inner flap at the bottom are continuously provided at the lower edge, and the above-mentioned side plates are joined by a joining margin to form the body of the body. Between the side plates, a Z-shaped partition plate having a height corresponding to the side plates and bisecting the inside of a substantially Z-shaped box is fixed, and a lower portion of the side plates is laterally mounted on a pair of opposed wide side plates. A cutout band to be opened and intermittent cut lines extending upward from both sides of the side plate starting from the cutout band and reaching both ends of the ridge line of the side plate and the top outer flap are provided.

[0007] The second aspect of the present invention is the corrugated cardboard box with a Z-shaped partition according to the first aspect, wherein the Z-shaped partition plate is formed of a cardboard sheet thinner than a sheet constituting the corrugated cardboard box body.

[0008] Even though the cardboard boxes may be piled up in a warehouse or a storefront, the upper box has a Z-shaped partition plate whose lower surface has a top flap of a lower box and a Z-shaped partition located below the upper flap. As a result, the boxes can be stacked in a stable state, and the boxes in the lower stack can be prevented from being crushed.

When displaying the goods stored in the cardboard box at a store, the cutting band on the side is cut, and then the intermittent cut line is cut to remove the upper part of the side plate and the outer flap. When the open boxes are stacked and displayed in large quantities, the inner products are conspicuous at least in the uppermost box, and the products can be visually recognized from both front and rear directions of the boxes.

[0010]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention. This corrugated cardboard box 1 is assembled from an A-flute double-faced corrugated cardboard sheet 10 composed of a front liner, a core, and a back liner. As shown in FIG. 1, a pair of side plates 11a, 11b, 12a, and 12b each having a wide width and a narrow width are alternately arranged in a lateral direction, and the upper and lower edges of each of the pair of side plates are outside the top or bottom. The flaps 14a, 14b or 16a, 16b are connected to the inner flaps 15a, 15b or 17a, 17b, and the above-mentioned side plates are joined together by a connecting margin 13 to be applied internally.

In the double-faced corrugated cardboard sheet, the wide side plates 11a and 11b are provided with band-shaped cutouts 18a and 18b for opening the lower portions of the side plates in the horizontal direction, and both side portions of the side plates are set upward starting from the band-shaped cutouts. , And cut lines 19a, 19a, 19b and 19b are provided to reach both ends of the ridge line of the side plate and the outer flap of the top portion. H-shaped cut lines 20a, 20b are formed at the centers of the band-shaped cutout portions 18a, 18b.

FIG. 2 shows an expanded state of the Z-shaped partition plate used in the present invention. This Z-shaped partition plate is formed by using a double-faced corrugated cardboard sheet 30, but uses a base paper with a lower U.S. tsubo or a sheet in which the base paper flute configuration is changed, which is lower in strength than the material forming the box body. Specifically, a double-faced cardboard of B flute is used. In FIG. 2, reference numeral 31 denotes a partition wall having a height corresponding to a wide side plate. Reference numerals 32a and 32b denote joining pieces continuously provided at both ends of the partition wall, which are approximately half the size of the narrow side plate 12. As will be described in detail later, this partition plate is attached in a substantially Z shape between a pair of narrow side plates of the box main body, and divides the inside of the box into two in the vertical direction.

FIG. 4 shows a process of assembling the box from the two cardboard sheets, and FIG. 3 shows a packaged state. At the time of assembling, the joint piece 32b of the Z-shaped partition plate is fixed to one narrow side plate 12b, then bent so that the wide side plates 11a and 11b face each other, and the other joint piece 32a is joined to the other side. In addition to being fixed to the narrow side plate 12a, the connecting margin 13 is fixed to the side plate 12b.

Then, the inner flaps 17a and 17b at the bottom are folded inside the box, the outer flaps 16a and 16b at the bottom are folded inward, and the seam of the outer flap is closed using tape sealing or hot melt. Then, insert a soft packaging bag, a product that is vulnerable to external pressure or a product that cannot be self-supporting from the top side, fold the top side flap in the same way as the bottom side, and seal it. Cover both sides and bottom.

[0015] Even if the packaged products are stacked in a warehouse or piled up in a store as shown in FIG. 6, the upper cardboard box has a lower surface whose upper flap is the lower flap of the lower box. , And is supported by a substantially Z-shaped Z-shaped partition plate having the same height as the side plate provided in the box, so that even if a large load is applied to the lower stacked box in the stacked state of the boxes. In addition, it is possible to prevent the side plate from bulging and the box from collapsing, and even if the box is slightly displaced, it does not collapse.

When a large number of products stored in the cardboard box are displayed at a store, first, the H-shaped cutting lines 20a, 20b are raised to the left and right, and the cutting bands 18a, 18b are placed near both ends of the side plates 11a, 11b. Then, the intermittent cut lines 19a and 19b are cut, and the upper portions of the side plates 11a and 11b and the outer flaps 14a and 14b are removed as shown in FIG. This removal is performed on both side plates 11a and 11b and the outer flaps 14a and 14b. By stacking these open boxes and displaying them in large quantities, the products can be seen from both the front and rear directions of the boxes, and at least the innermost box is conspicuous at least at the top box, and the product appeals to consumers. Is improved.

As shown in FIG. 7, the corrugated cardboard box 1 used in the distribution stage is discarded by flattening the body of the rectangular cylindrical body, and at this time, a Z-shaped partition plate is mounted in the box. Even so, this partition plate is made of a cardboard sheet that is thinner than the sheet that makes up the cardboard box body, so that the swelling of the box at the time of disposal can be reduced, and the accumulation and bundling of the disposal boxes becomes easier. .

[0018]

[Effect of the invention]

 As described above, according to the corrugated cardboard box of the present invention, the compressive strength is not inferior to that of the conventional one in which the partition plate is integrated, and therefore, it is vulnerable to external pressure such as a soft packaging bag. It facilitates the transportation, storage and storage of goods and products that cannot be self-sustained, and when stacked at retail stores and displayed in large quantities, the cutting means provided on the side of the box will tear off the middle of the side of the box. It is easy and the goods in the box can be easily seen, so that a packaging box with high visibility of the goods is provided. Furthermore, when disassembling and disposing of packaging boxes after distribution, it is possible to achieve reduction of garbage and to reduce the swelling of the boxes at the time of disposal, which makes it easy to accumulate and bind the disposal boxes. It has excellent properties.
