Description

Carton layered structure

This creation has a layered structure of carton, especially a carton.

Carton is an item that is often used in daily life. Most of the goods are packed in carton, especially mobile electronic products, which are almost necessarily packed in carton. Most of the electronic products on the market include a body and accessories. In order to facilitate the boxing, the inside of the carton is generally divided into several spaces, respectively, for the body and accessories. Take the mobile phone as an example, the multi-section is divided into upper and lower layers, the upper layer is equipped with the body, and the lower layer is equipped with accessories. A general method of partitioning is to insert a tray into the carton to hold the body, and a step is provided on the inner wall of the carton to support the periphery of the tray. Conventional cartons are often made by laminating two layers of cardboard, and the steps are formed by arranging the steps on the edges of the two-layer cardboard. A disadvantage of the prior art is that the preparation of the two-layer cardboard and the laminating process all result in unnecessary waste of costs.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The purpose of this creation is to provide a layered structure of a carton incorporating a carrier tray.

In order to achieve the above object, the present invention provides a layered structure of a carton comprising an inner box, an outer cover and a carrier tray. The inner box has a first opening, and an inner edge of the first opening forms a stepped surface. The outer edge of the carrier disk is formed with a flange, and the carrier disk is disposed on the first opening and the flange is supported by the step surface. The outer cover has a second opening, and the second opening is opposite to the first opening, and the outer cover covers the first opening and covers the outer side of the inner box.

Preferably, in the layered structure of the foregoing carton, the four corners of the side of the inner box respectively have a first rounded corner.

Preferably, in the layered structure of the foregoing carton, the four corners of the side of the outer cover respectively have a second rounded corner.

Preferably, the layered structure of the foregoing carton has a radius of the first guide fillet larger than a radius of the second guide fillet.

Preferably, in the layered structure of the foregoing carton, the side walls of the inner box are inclined outward to form a draft angle.

Preferably, the layered structure of the foregoing carton has an angle of draft angle of between 1 and 2 degrees.

Preferably, in the layered structure of the foregoing carton, the physical thickness of the carrier tray is between 1 mm and 1.5 mm.

Preferably, the aforementioned carton has a layered structure having a flange having a width of between 1.5 mm and 2 mm.

Preferably, in the layered structure of the foregoing carton, a through hole is formed through the carrying tray.

The layered structure of the paper box of the present invention has an inner edge of the inner box integrally formed to form a step surface to support the carrier tray. Compared with the prior art, the process of sticking the sticker board can be omitted, and the preparation of the material can be reduced, thereby reducing the manufacturing cost.

Referring to the first to third figures, a preferred embodiment of the present invention provides a layered structure of a carton comprising an inner box 100, an outer cover and a carrier tray 300. In the present embodiment, the inner casing 100 is preferably a rectangular open box body, which is preferably molded by injecting pulp into a mold, and has a bottom plate 101 and four first side plates 102. The bottom plate is substantially rectangular, the four first side plates 102 are connected to each other to surround the bottom plate 101, and the first side plates 102 are respectively vertically connected to the four sides of the bottom plate 101, thereby forming a first between the four first side plates 102. Opening 110. A first dowel 103 is formed on the connecting side of any two connected first side plates 102. In addition, a stepped surface 111 is formed on the inner edge of the first opening.

Referring to the fourth and fifth figures, the four first side plates 102 are preferably slightly inclined outward from the sides of the bottom plate 101 to form a draft angle A, and the angle of the draft angle A is preferably Between 1 and 2 degrees.

Referring to the first, fourth and fifth figures, in the embodiment, the carrier tray 200 is preferably a rectangular disk body, which is preferably molded by injecting a pulp into a mold, and has a carrier plate 210 and A ring wall 220 surrounding the carrier plate 210. The carrying plate 210 has a rectangular shape, and the carrying plate 210 defines a through hole 211. The ring wall 220 is connected to the four sides of the carrier plate 210, and a flange 221 is formed on the outer edge of the ring wall.

The carrier tray 200 is disposed on the first opening 110 and the flange 221 is supported by the step surface 111. The physical thickness T of the carrier plate 210 and the ring wall 220 is between 1 mm and 1.5 mm, and the width D of the flange is compared. It is preferably between 1.5 mm and 2 mm to provide sufficient support for the carrier disk 200. Further, the through hole 211 is provided for the user to insert the finger to facilitate the removal of the carrier 200 from the case 100.

Referring to the first to fourth figures, in the embodiment, the outer cover 300 is preferably a rectangular opening cover having a cover plate 301 and four second side plates 302. The cover plate 301 is substantially rectangular, the four side second side plates 302 are connected to each other to surround the cover plate 301, and the second side plates 302 are respectively vertically connected to the four sides of the cover plate 301, thereby being in the four second side plates 302. A second opening 310 is formed therebetween. Moreover, a second turn-around fillet 303 is formed on the connecting side of the second connected second side plate 302. Preferably, the radius of the first conductive fillet 103 is larger than the radius of the second conductive fillet 303. The second opening 310 is opposite to the first opening 110 , whereby the cover plate 301 covers the first opening 110 and the four side second side plates 302 respectively cover the outer sides of the four first side plates 102 .

The present invention forms a stepped surface 111 integrally formed by the inner edge of the first opening 110 of the inner casing 100 to support the carrier tray 200. Compared with the conventional technology, the two layers of cardboard are stacked Forming the ladder, the structure of the present invention can omit the process of sticking the sticker board and reduce the preparation of materials. Therefore, the layered structure of the paper box of the present invention is lower in cost than the prior art.

Furthermore, the layered structure of the paper box of the present invention has a radius of the first guide fillet 103 of the inner box 100 being larger than a radius of the second guide fillet 303 of the outer cover 300. When the inner box 100 is engaged with the outer cover 300, the first guide fillet 103 is located inside the second guide fillet 303. Thereby, a space is formed between the first side plate 102 and the second side plate 302 for the user to push to facilitate separation of the inner box 100 and the outer cover 300.

Moreover, each of the first side plates 101 of the inner casing 100 is outwardly inclined to form a draft angle A, thereby not only facilitating the demolding operation after the inner casing 100 is molded, but also reducing the friction between the inner casing 100 and the outer cover 300. It is easy to separate the inner case 100 from the outer cover 300.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of the patents of the present invention. Other equivalent variations of the patent spirit using the present invention are all within the scope of the patent.
