Description

[Technical field]

[0001] The present invention relates to adapting the truss handle type box container shown in Patent Application No. 2021-58706 to wrap-around packaging, thereby reducing the amount of base paper used while maintaining strength, thereby reducing costs. [Background technology]

[0002] Conventionally, in order to put contents into a box container made of cardboard or the like and carry it, there have been setup methods in which handle holes are drilled into the side wall so that it can be carried with both hands, or a plastic handle is attached to the top. However, there was no low-cost box container with a truss handle on the top for wrap-around packaging that could be carried with one hand. [Prior art documents]

[0003] Patent application 2020-115217 Patent application 2021-58706 Summary of the Invention [Problem to be solved by the invention]

[0004] The subject of this application is how to reduce the cost of the truss handle type box container that the author has invented while maintaining its strength. [Means for solving the problem]

[0005] We discovered that by making the top surface a three-layer rigid structure to maintain the strength of the truss handle part of the box container, and by using wrap-around packaging to minimize unnecessary overlapping of paper in order to reduce costs, and by keeping the inner and outer side flaps of the side wall to a minimum, it is possible to create a truss handle type box container that can be carried with one hand at a cost equivalent to or lower than Type A (commonly known as a mandarin orange box). Effect of the Invention

[0006] According to the present invention described in claim 1, first, the use of base paper in wrap-around packaging and set-up packaging (tangerine box) for box containers of the same volume is shown in units of cm in numerical simulations as shown in [Figure 1] and [Figure 2]. The development diagram of the wrap-around packaging specification [Figure 1] shows 5293 cm 2 In contrast, the setup packaging specification (tangerine box) of the same volume [Figure 2] is 5436 cm 2 By using a truss handle type box container with wrap-around packaging specifications, the side flaps are provided on the narrow side walls in this figure, but by providing them on the wide side walls, the usage rate of base paper can be further reduced and costs can be cut.

[0007] According to the present invention as described in claim 2, by forming handles along the short sides AA', BB' of the outer top wall OCW, as shown in (6-A) of [Figure 6], bending of the top surface can be prevented, which is effective for lifting heavy objects.

[0008] According to the present invention described in claim 3, in the case of Type A containers (commonly known as mandarin orange boxes), the flap on the top surface can be opened and closed, so it was not possible to completely seal it. However, by using wrap-around packaging specifications, the side wall can be opened and closed, and by adjusting the length of the inner and outer side flaps, it is possible to completely seal the container. Furthermore, by fixing the top reinforcing flap OFA1 to the inner top wall ICW at adhesive surface CB1, and by fixing the outer top wall OCW to the inner top wall ICW at adhesive surface CB2, a three-layer rigid top structure is formed by preventing misalignment between the surfaces of the top reinforcing flap OFA1, the inner top wall ICW, and the outer top wall OCW, and a diamond-shaped truss handle portion with one upper layer and two lower layers as shown in (6-B) of [Figure 6] can be formed thereon.

[0009] According to the present invention described in claim 4, in order to smoothly form a single truss handle portion on the top and a double truss handle portion on the bottom, the push flap PF is pressed with the thumb and middle finger, and folded at the valley fold line 11A, while simultaneously pushing down the lower truss handle portions TT1 and TT2 and lifting up the upper truss handle portion TT3, thereby forming a rhombic truss handle portion as shown in (6-B) of [Fig. 6]. Furthermore, in order to make it easier to form the lower truss forming handles TT1 and TT2, punched holes BK1 are formed at both ends of the truss forming handle TT2, and further, in order to prevent the upper truss forming handle TT3 from collapsing, the length of the truss forming handle TT1 is made shorter than that of TT3, thereby forming a collapse prevention guard GD for the upper truss forming handle, thereby enabling the smooth formation of the truss forming handle.

[0010] In addition, as shown in (4-A) of Figure 4, it can also be used as a truss handle type box container with set-up packaging specifications by closing one of the inner and outer side flaps on both sides and leaving the other inner and outer side flap open.

[0011] With wrap-around packaging specifications, when delivering cases, they can be piled up as shown in the development diagram in [Figure 1] and supplied to the production line. Alternatively, the top reinforcing flap OFA1 can be folded along the back cut valley fold line ST1 and attached to the inside top wall ICW at the adhesive surface CB1, and then folded along the valley fold line 9A as shown in (7-A) to form two even layers. As shown in (7-B), they can be bundled and stacked in units of several dozen sheets, thereby reducing storage space.

[0012] As shown in (5-B) of [Fig. 5], after packaging is completed, both sides are opened to remove the contents, and then, as shown in (5-C), the package can be flattened by folding it along the valley fold lines 7A and 9A, making it easy to reuse. [Industrial Applicability]

[0013] This is a wrap-around packaging truss handle type box container made of cardboard sheets, etc., and by eliminating unnecessary parts of the base paper, it is possible to reduce costs compared to the A type (commonly known as the mandarin orange box). Combined with the addition of a rigid truss handle, it is suitable for storing bottled and canned goods as well as mackerel. TIFF0007670294000001.tif10170It is expected to become widely used and widespread as a box container that can be carried by hand, stacked, and removed from the side. [Brief description of the drawings]
