Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a boat-shaped box used as an inner box of a double box and a C-shaped cardboard box, and more specifically, to a boat-shaped corrugated box with no cuts or cut faces or joints on the bottom and peripheral sides thereof. In addition, it is to provide a boat-shaped cardboard box that can be folded without bending the bottom surface.

[0002]

[Prior art]

 Conventionally, there are so-called A-type, B-type, and C-type cardboard boxes.

[0003]

[Problems to be solved]

 These A-type and C-type types have a slot in the deploying piece, so that a cut face is formed when the flaps are butted or overlapped with each other, and the B-type type has two or three pieces. A cut surface is inevitably formed between the peripheral surface and the bottom surface by assembling the deployment piece (insertion type, splicing type), and the cut surface and joint margin are also formed by the assembly on the peripheral side surface. Since it had a cut surface on the bottom surface or the peripheral side surface, it was not watertight (waterproof). Therefore, it is not preferable for packaging fresh fish, frozen foods, meat, cold fruits such as foods for the purpose of keeping cold and waterproof, and fruits.

In addition, after assembling the unfolding piece and once forming it into a box shape, in order to fold it, the joining material such as the adhesive, the double-sided tape, and the flat wire for joining is removed to form the original unfolding piece. It was closer to disassembling than folding. Therefore, it had to be reassembled into a box shape.

Further, considering a foldable ruled line on the bottom surface and the width side surface in consideration of a foldable piece without a cut surface or a joint margin on the bottom surface and the peripheral side surface without having a slot in the expansion piece. When I tried to fold it by opening the side face and bending the bottom face inward, it took a lot of time and effort to fold it, and the folded case did not become a flat surface, and there were many overlapping parts, and there was a lot of rebound and it was not easy to tie it. Moreover, since the ruled lines are formed on the bottom surface, there is a possibility that surface cracks may occur in the liner, which may cause water leakage.

The present invention has been made in view of the above points. Firstly, there is a water-tight (waterproof) boat-shaped corrugated box and a second slot having a cut surface and a joint margin on the bottom surface and the peripheral side surface of a slot. A boat-shaped cardboard box that is water-tight (waterproof) and can be folded without bending the bottom surface. Thirdly, this folding is easy and stable even when tied flat and good for distribution and transportation. The purpose is to provide cardboard boxes.

[0007]

[Means for solving the problem]

 Means for solving the above problems by the present invention is to provide a lengthwise side and a width side around a bottom surface through bottom creases, and a folding flap between both sides through height creases. A top surface flap is provided at the tip of the side surface, and a side surface holding flap is provided at the end of the width side surface. These bottom surface, length side surface, width side surface, folding flap, top surface flap, side surface pressing flap are made the same body without cuts. Consecutively install, form a folding ruled line on the folding flap, fold the folding flap halfway with this folding ruled line and fold it back to the width side or length side, and cover the folding flap with the side holding flap or the top flap. Water-tightness (waterproofness) is retained by fixing, and the bottom ruled line is provided either on the length side face and the top face flap, or on the width side face and the side holding flap. Against It is possible to fold by providing continuous folding lines that form an angle of 45 degrees, and a V-shaped cut is provided near the intersection of the folding lines at the outer center of the top flap or side holding flap. By providing it, the folding can be easily performed.

【Example】

 Some embodiments of the present invention will be described with reference to the drawings. The corrugated box shown in FIGS. 1, 5 and 7 has liners on both sides of a corrugated core which is well known in the technical field of this type. Using double-sided corrugated board, the length side B and the width side C centering on the bottom surface A are through the bottom ruled line a, and the folding flap D is the height ruled line between the length side B and the width side C. The side surface holding flap E is attached to the tip of the width side surface C via the side surface ruled line c via b, and the top surface flap F is attached to the tip of the length side surface B via the top surface ruled line d without a slot. This is an assembly of the developed parts Y having the shapes as shown in FIGS. 2, 6 and 8 which are punched in a state of being integrally connected.

Corrugated board is a so-called well-known form in which a liner is attached to both sides of a corrugated core, and a plastic film or the like is laminated on the liner on the outer surface, the inner surface, or both sides, or by chemical treatment or paraffin processing. The corrugated cardboard is punched out to form the unfolded expansion part Y as described above, and the folding flap D is formed with folding ruled lines m. The bottom ruled line a of the unfolded part Y is bent inward to erect the length side face B and the width side face C, and the folding ruled line m of the folding flap D is half-folded inward (Fig. 1, Fig. 3A). The half-folded folding flap D is folded back to the outside of the width side surface C, and the side-face pressing flap E is folded back to the outside (FIG. 1) by the side ruled lines c and c formed at a predetermined interval and half-folded. Cover the folding flap D and the width side surface C, and fix the half-folded folding flap D, the width side surface C and the side pressing flap E with a bonding material such as an adhesive, a double-sided tape or a bonding flat wire. Assemble.

At the time of this assembly, the folding ruled line m of the folding flap D may be half-folded not to the inside but to the outside (FIGS. 3B and 5), and the half-folded folding flap D may be outside the width side surface C. Instead, it can be folded either inside the width side C (FIG. 3B), outside the length side B (FIG. 7), or inside the length side B (FIG. 5). Further, the side-face pressing flap E is not on the outside but on the inside (FIG. 3B), or on the outside (FIG. 7) by the point surface ruled lines d and d formed with the top-face flap F at a predetermined interval, or on the top. It is also possible to fold back the surface flap F either inside (FIG. 5) along the dotted surface ruled lines d, d. In this way, the side presser flap E or the top surface flap F is folded back and half-folded. The folding flap D and the length side surface B or the width side surface C are covered with the folding flap D, the length side surface B or the width side surface C, and the side pressing flap E or the top surface flap F. As mentioned above, it is optional to fix and assemble them with the joining material.

The folding flap D is continuously formed in the same body through the height ruled line b without providing a slot between the length side surface B and the width side surface C, and its outer edge is slightly inner as shown in the figure. The side is tapered or is formed in a right angle or an arc shape (not shown), and the folding ruled line m for half folding the folding flap D is formed at an angle of 45 degrees with respect to the height ruled line b. Is formed over the intersection of the bottom ruled line a and the center of the outer edge, and a notch 2 is provided at the outer tip of the folded ruled line m 1 so as to facilitate folding.

By assembling as described above using the deployable parts Y formed in a state where they are continuously connected to the same body through each ruled line without slots (cuts) as described above, cuts are made on the bottom surface and the peripheral side surface. A cardboard box with no surface or joint margin and excellent in watertightness (waterproofness) can be obtained.

In order to be able to fold such a cardboard box, either the length side surface B and the top surface flap F or the width side surface C and the side surface pressing flap E are arranged on either side. The convolutional ruled line n is linearly and continuously provided by inclining from both intersections of the bottom ruled line a so as to form an angle of 45 degrees with respect to the ruled line a. Further, the V-shaped cut 1 is provided at the substantially outer center of the top flap F or the side pressing flap E and near the intersection o of the folding ruled line n, so that the folding can be easily performed.

The top surface flaps F are provided in series at the tip of the length side surface B via the top surface ruled line d, and the convolution ruled lines n of the length side surface B are also formed continuously on this top surface flap F. Depending on the size of the box, if necessary, a V-shaped cut 1 is provided at the outer substantially central portion. This top surface flap F is folded back inward along the top surface ruled line d after the side presser flap E is folded back to the outside or inside via the side surface ruled lines c and c to cover and fix the width side face C and the folding flap D. The side presser flap E is overlapped with the top surface of the side presser flap E to form a wave-reversing piece or a lid piece on the length side surface B side.

The folding ruled line n is for folding the length side surface B or the width side surface C inward, and the length side surface B is formed at an angle of 45 degrees with respect to the bottom ruled line a from both intersections of the bottom ruled line a. And the top surface flap F or the width side surface C and the side surface pressing flap E are inclined in a straight line.

The cut 1 has a V-shaped (triangular surface) cut-out relief formed at the substantially outer center of the top flap F to facilitate folding. It is formed so as to coincide with the intersection point o of the above, or be located inside the vicinity of the intersection point o, and the cut edge also coincide with the convolutional ruled line n or be located inside the ruled line n. This cut 1 is unnecessary depending on the size and size of the box. That is, when the folding ruled line n has a shallow depth or an elongated one that intersects the outer edge of the top flap F or outside the outer edge, the folding when the top flap is folded together with the length side surface. If the parts do not overlap, the cut edge 1 may not be provided.

In the present invention, both side surfaces having different lengths are provided, and one long side is the length side surface and the other short side is the width side surface, but one side is the same length side and the other is the width side surface. It may be a side surface, and on the other hand, the shorter one may be the length side surface and the other long side may be the width side surface. In some cases, the side surface pressing flap E and the top surface flap F may have opposite configurations. Also, there is no change in action and effect.

[Effect of device]

 According to the present invention, a bottom side has a length side and a width side via a ruled line, a folding flap is provided between both sides via a height ruled line, and a top flap is provided at the tip of the length side. At the same time, a side presser flap is provided at the tip of the width side face, and the bottom face, the length side face, the width side face, the folding flap, the top face flap, and the side pressing flap are connected to the same body without a cut, and a folding ruled line is formed on the folding flap. Form it, fold the folding flap halfway with this folding ruled line and fold it back to the width side surface or the length side surface side, and cover the folding flap with the side presser flap or the top surface flap to fix it on the bottom surface or the peripheral side surface. It has no cut surface and is excellent in watertightness (waterproofness). It is suitable for foods such as fresh fish, frozen foods, meat, cold fruits, etc. that have the effect of keeping cold and water, and fruits.

Further, a convolution ruled line having an angle of 45 degrees with respect to the bottom ruled line is continuously provided on either one of the length side face or the width side face and one of the top face flap or the side face holding flap. At the same time, a folding ruled line is formed on the folding flap, the folding flap is half-folded by this folding ruled line and folded back to the width side surface or the length side surface side, and the folding flap is covered and fixed by the side holding flap or the top surface flap. Since a corrugated piece is formed on the upper surface of the length side surface to prevent splashing of molten water, and when the width side surface is folded inward, the length side surface expands outward and the folding ruled line folds inward. Be done. Also, to return the folded product to its original box shape, simply open it with the side presser flaps and it will become the original box shape, which is quite easy.

Furthermore, by providing a V-shaped cut near the center of the outer side of the top flap or the side pressing flap and near the intersection of the folding ruled lines, even if the top flap is folded, a relief is formed by the V-shaped cut. The surface flaps can be easily folded into a flat shape without overlapping, and even if a number of flat boxes are stacked and bound together, it is stable and very good in terms of flow transportation.
