Abstract

(57) [Summary] (Modified) [Purpose] To provide a pollution-free, completely waterproof cardboard box. [Structure] A Thompson die-cut box of corrugated cardboard that uses a water-repellent liquid such as a water-repellent liquid coated on the inside or a plastic film, a waterproof liner, and a water-repellent liner coated with an aqueous waterproof liquid on the outer surface. The upper and lower side plates, side plate ridges, fixed flaps, and locking tongues are provided in series vertically above and below the central bottom plate, and side plates and left and right butt flaps are provided in series on the left and right, and a folding ruled line for preview is provided almost at the center of the butt flap. In addition, bent reinforcing plates and butt support plates sandwiching the center diagonal fold line are provided at the four corners of the top, bottom, left, and right side plates, and the fold support plate and butt support plate are folded inside the diagonal fold line to stack the upper and lower side plates. Butt the butt support plates to the outside. After that, the upper and lower fixing flaps are bent outward, and the support plate is wound and fixed by the locking tongues arranged in series. Then, the left and right butt flaps are bent, and the butt flaps are sealed with waterproof tape from the inside using a tape laying board.

Description

[Detailed description of the device] Currently, styrofoam toro boxes are the mainstream for packaging fresh fish, but this toro box is the most polluted waste and has become a major social problem.

 This invention is made by using this Toro box as a non-polluting, general-purpose cardboard that can be reused as waste paper. Conventional standard paper corrugated board cannot be waterproof even to the core even if waterproof liners are used on both sides. It was said that there was no. The present invention forms a box having no internal cut surface so that water does not leak, as described below.

 The structure will be explained below with reference to the drawings. A double-sided and double-sided corrugated cardboard Thomson punch die cut using a waterproof liner with a plastic film attached to the inner surface of a corrugated board and a water repellent liner coated with a synthetic resin solution on the outer surface. In the box, the right side plate (2) the right butt flap (6) the left side plate (2a) the left butt flap (6a) via folding ruled lines (18, 18a, 11, 11a) to the left and right of the box center bottom plate (1), respectively. ), A folding crease line (19, 19a) for previewing is provided in the center of the left and right butt flaps, and the folding crease lines (10, 14, 15, 10, 10a, 14a, 15a) are provided above and below. Plate ridge (7) Upper fixing flap (8) Upper locking tongue (9) Lower plate (3a) Lower plate ridge (7a) Lower fixing flap (8a) Lower locking tongue (9a) , And bent lines at the four corners of the top, bottom, left and right sides (12, 13, 12a, 13a, 12b, 13b, 12c, 13c) through the diagonal diagonal ruled lines (16, 16a, 16b, 16c) in the center and the support plate score line (17, 17a, 17b, 17c) ), And butt support plates (4, 4a, 4b, 4c) are provided, and diagonal folding ruled lines (16, 16a, 12b, 12c) is bent inward and the opposite folding ruled lines (13, 13a, 13b, 13c) are bent outward, and the supporting plates are butted. After that, the folding ruled lines (14, 14a) are bent outward and the butt support plates are wound and fixed by the locking tongues (9, 9a) connected to the folding fixing flaps (8, 8a). Then, as shown in FIG. 6, a waterproof adhesive tape is attached to the tip of one of the butt flaps so as to protrude from the inside by about half. The butt flap (6a) with the waterproof tape attached is bent so that the fold line (11a) is bent at right angles so that the waterproof tape rides on the tape-laying board, and then one butt flap (6) is applied to both flaps. Bend them so that they completely face each other, and press the tape-laying board as the underlay from above. Then, when the tape-laying board is pulled out, both flaps are completely joined from the back side with waterproof adhesive tape. After that, as shown in FIG. 4, the left and right ends of each flap closely contact the side plate ridges (7, 7a) as seen in the conventional double-sided open box box (A type carton), and also cover the four corners. Stick the waterproof adhesive tapes (21, 21a) so that you can do things, and stick the reinforcing tape (20) in the center of the lid just in case, then the waterproof corrugated cardboard is completed. The tape-laying plate (23) should be as thin as possible, be made of a smooth material that does not bend even when pressure is applied, have a length sufficient to straddle the ridge edges of the upper and lower plates, and have a width dimension not less than the waterproof tape width. The best choice is hard plastic or iron. In addition, when used in a toro box for fresh fish, the contents must be visible when auctioning at a fish market, and as shown in Fig. 5, the upper tapes (21, 21a) on both width surfaces are used for the right flap preview ruled line. Cut from (19) to the left flap preview ruled line (19a) with a cutter knife, etc., further cut the tape at the flap abutment part and bend each preview ruled line to the outside without opening all flaps Are formed, and they can be piled up as they are. Further, it goes without saying that if each of the folding ruled lines 13, 13a, 13b, 13c, 14, 14a, 15, 15a, 19 and 19a is made into a reverse rule, it becomes easier to assemble. By forming a box as described above, it is not possible to use it as a liquid transportation container that can fill a box with liquid, but melted ice to maintain freshness and sewage from catch fish will collect on the bottom. Toro boxes for fish, etc. can withstand sudden starts, stops, climbs up and down slopes, and rocking of water due to stacking and loading, and width side locking tongue folds (15, 15a). ) Or 3 layers, and a practical handbag is formed without making holes. Currently available corrugated board waterproof liners are water-repellent liners coated with synthetic resin liquid and completely waterproof liners with plastic film attached.The water-repellent liner remains as waste paper, but the completely waterproof liner does not. It cannot be reused as waste paper. However, since the attached plastic film can be easily peeled off, it can be reused as waste paper if the film is peeled off after use. Therefore, this toro box uses a completely waterproof liner only on the inside of the corrugated ball, and a water repellent liner that can be stacked on the wet floor of the fish market etc. on the outside, making it easier to reuse as recycled paper.

In addition, since it is only punched with a Thomson machine, productivity is extremely good, and because it can be easily assembled, it can be assembled on-site like a farm tomato or strawberry box, and it can be shipped in flat plates, so the fare is cheap and stock and storage It has to be said that the effect is very large, because it does not take up much space and it is also pollution-free.
