Description

  The present invention relates to a paper box having high compressive strength, and more particularly to a structure of a paper box for leaving fruits and articles.

  Paper boxes are widely used to leave fruits and other items because they are less prone to environmental pollution than plastic ones. However, paper boxes according to the prior art are assembled with metal pins and adhesives, and even if metal pins are used or adhesives are used, environmental pollution problems occur after disposal. Also, a general paper box is manufactured from a paper material, is relatively soft, and cannot withstand the weight due to impact or stacking. Therefore, devising a structure of a paper box having a high pressure resistance and being environmentally friendly has been an important issue in the industry.

  The structure of Patent Document 1, which is a structure according to the prior art, is provided with a central substrate serving as a bottom surface of a paper box, and provided with front and rear surface plates and left and right surface plates each provided with a stretched plate along the periphery of the central substrate. The reinforcing plate extends and is supported on the inner surfaces of the left and right side plates, the extending plates of the left and right side plates press and support the extending plates of the front and rear side plates, and the reinforcing plates on both sides thereof are supported on the outer surfaces of the front and rear side plates. Convex portions are provided at the left and right upper ends of the front and rear surface plates, respectively, through the through holes of the stretched plates of the left and right surface plates, and engaging holes are provided at the left and right at the connection portion between the front and rear surface plates and the central substrate. The stopper is positioned.

  However, the structure of the paper box according to the prior art has the following problems. Since all the surrounding plates have a single layer structure, when an impact is received from each direction during the transportation process, the impact cannot be withstood and the internal article is damaged. In addition, since the strength in the vertical direction is particularly insufficient, paper boxes cannot be stacked. As a result, a lot of labor is required during transportation, and an efficient arrangement during transportation is impossible, resulting in extremely high transportation costs. To be high. In addition, the overall structure is complicated, and not only is it time-consuming to manufacture a paper box, but also it takes time to assemble and disassemble and is not economical.

In light of the above-mentioned problems in the prior art, the inventor of the present invention, based on many years of experience, repeatedly studied and improved, and finally devised the present invention.
Taiwan Utility Model Notification No. 577442

  The purpose of the present invention is a structure in which two or more layers of paper boards around each other overlap each other, can withstand impacts from each direction, and can stack multiple paper boxes. An object of the present invention is to provide a paper box having a high pressure strength that can save the transportation cost.

  In order to solve the above-mentioned object, the paper box with high pressure strength of the present invention includes a central substrate which is a bottom surface of the paper box, and a front plate, a rear plate, and a left middle plate which are bent upward at the four periphery of the central substrate. A plate and a right intermediate plate are provided, and a left front plate and a right front plate covering the front of the left intermediate plate and the right intermediate plate are provided on both sides of the front plate, respectively, and are provided on the upper edges of the left front plate and the right front plate. Is provided with a left front reinforcing plate and a right front reinforcing plate that are bent inward, respectively, and a left rear plate and a right rear plate covering the rear of the left intermediate plate and the right intermediate plate are provided on both sides of the rear plate, respectively. A left rear reinforcing plate and a right rear reinforcing plate, which are bent inward, are provided on upper edges of the left rear plate and the right rear plate, respectively. A front reinforcing plate and a rear reinforcing plate that are bent inward are provided on the upper edges of the front plate and the rear plate, respectively, and a separation groove is formed between the front reinforcing plate, the left front reinforcing plate, and the right front reinforcing plate, respectively. Separation grooves are formed between the reinforcing plate, the left rear reinforcing plate, and the right rear reinforcing plate, respectively.

  Since the paper box according to the present invention is an open box without a lid, it can be arranged directly on the sales floor with fruits and the like, and the working time can be greatly reduced. Moreover, since the metal pin is not used, the metal pin is caught during transportation or disassembly and the worker is not injured. In addition, since the boards around the paper box are all stacked in multiple layers, they can withstand impacts from each direction, and multiple paper boxes can be stacked, so labor and transportation when moving the paper box, etc. Can save the cost. In addition, vent holes are provided on the central substrate, the front plate, and the rear plate, and the inside has air permeability, so that the freshness of the fruit can be maintained and it does not easily rot.
