The present invention relates to a packaging system including an electronic paper display panel, and more specifically, a side wall portion including a first side wall, a second side wall, a third side wall, and a fourth side wall, and a floor connected to the bottom of the side wall portion. A first body portion including a bottom portion and a coupling portion formed by being connected to the top of the side wall portion; a first cover part coupled to the coupling part to cover an upper surface of the first main body and including a receiving part formed on the upper surface; E-paper display panel capable of displaying delivery information; and a fixing unit capable of accommodating and fixing the electronic paper display panel. It relates to a packaging system including an electronic paper display panel.

With the recent development of the transportation industry, it has become possible to transport food that requires rapid transportation in addition to existing cargo without an expiration date. Food spoils quickly when exposed to room temperature, so it must be stored at low temperatures to maintain freshness.

Therefore, when transporting food, a separate transport means capable of freezing and refrigerating is required. However, when transporting small amounts of food individually, rather than transporting large amounts of food ingredients, frozen foods, etc., place dry ice or ice packs in the box containing the food to prevent spoilage of the food.

In general, packaging boxes manufactured to store or transport contents such as agricultural products, marine products, and livestock products that require heat and cold insulation are mostly made of various materials such as paper, cardboard, and Styrofoam.

When such a packaging box is made of Styrofoam, it not only provides waterproofing, thermal insulation, and cold insulation effects, but also protects the contents stored inside from shocks applied from the outside. However, the molded box body must maintain a constant volume to contain the contents. Because it was compression molded, there was a problem that it cost a lot of money to store and transport.

On the other hand, packaging boxes made of paper and cardboard are easy to manufacture and can be stored in an unfolded, stacked state and then simply assembled when in use, which has the advantage of reducing logistics costs, but because its constituent material is made of paper. Waterproofing was significantly reduced, and the warming and cooling effects did not reach the expected level, and at the same time, there was a problem in that the contents stored inside could not be properly protected from external shock.

In addition, the existing packaging system had no way to measure or know even if the packaging was damaged during transportation or the effectiveness of cooling and warming the indoor space was reduced. For this reason, there was a problem that when fresh products were damaged or defective during transportation, disputes occurred between consumers and suppliers over who was responsible.

In addition, since all existing packaging systems have a rectangular parallelepiped shape, even if only a few pieces are stacked in the process of storage after transportation and recovery, they take up a lot of space and take up a lot of logistics costs, and the invoice during the transportation process is problematic. There was a problem that if the invoice was damaged or wet, the writing on the invoice would smudge and could not be checked.

In particular, absolute structural stability was required during the delivery process, such as temperature-sensitive products that require constant temperature logistics, and packaging that required internal temperature maintenance was required, but there was a problem because a product that could solve these problems had not been developed.

Previously, there was a problem that the types of goods that could be delivered were limited because, like pharmaceuticals, structures that were sensitive to damage during the delivery process and required absolute structural stability had not been developed. In order to solve this problem, the present invention is intended to maintain a constant temperature during the delivery of medicines and have a structure with excellent insulation properties, and has the structure and physical properties as described later.

The packaging system including the electronic paper display panel according to the present invention includes a side wall portion including a first side wall, a second side wall, a third side wall, and a fourth side wall, a bottom portion connected to the bottom of the side wall portion and forming a floor, and It includes a first body portion including a coupling portion formed by being connected to an upper end of the side wall portion.

The packaging system including the electronic paper display panel according to the present invention includes a first cover part that is coupled to the coupling part to cover the upper surface of the first body part and includes a receiving part formed on the upper surface.

The packaging system including the electronic paper display panel according to the present invention is disposed inside the first main body, and has a second main body formed to accommodate the delivery product, and is coupled to the second main body to form the second main body. It further includes a second cover part formed to cover the upper surface of the unit, and a third cover part disposed between the second main body part and the second cover part to maintain the temperature inside the second main body part.

The packaging system including the electronic paper display panel according to the present invention includes a first vacuum insulation panel disposed between the second cover portion and the third cover portion, and a second vacuum insulation panel disposed between the first body portion and the second body portion. It further includes a vacuum insulation panel and a refrigerant disposed inside the second body portion.

Vacuum insulation panels are VIPs (Vacuum insulation Panels). VIPs are an insulating material that has a core material such as fumed silica wrapped in an outer shell, and is characterized by a thin thickness and higher insulating performance than general insulating materials. there is. Specifically, the vacuum insulation panel contains an open-cell hard plastic foaming agent or an inorganic material as a core material in an encapsulant made of a composite plastic laminated film with excellent gas barrier properties, depressurizes the inside, and then heat seals the gas barrier film forming the perimeter. It is manufactured.

The packaging system including the electronic paper display panel according to the present invention includes a first cover part, a handle part that can be pulled and separated from the first main body part by the user to facilitate separation from the first main body part, and the handle part. It is connected to the first main body and includes a locking portion configured to be released when the user pulls the handle portion.

As shown in Figures 2 and 3, in order to separate the first cover part from the first body part, the handle part 210 formed on the first cover part is first pulled in the direction of the arrow. When the handle is pulled in this way, the locking part 220 connected to the handle is released. This locking part is hung to prevent the first cover from being separated from the first main body after the first cover is coupled to the first main body. Since it is a device, the first cover part and the first body part can be separated by removing this locking device.

The packaging system including the electronic paper display panel according to the present invention includes a first convex protrusion and protrusion formed on the upper part of the second main body so that the second main body can be fixed and coupled to the second cover part and the first convex protrusion and protrusion. It further includes a first concave groove formed in the lower part of the second cover part so that the second cover part can be inserted, and a second main body part formed inside the side wall of the first main body part so that the second main body part can be fixedly coupled to the first main body part. It further includes a convex concavo-convex portion and a second concave groove formed on a side of the second main body portion into which the second convex concavo-convex portion can be inserted.

As shown in Figures 2 and 4, the second main body and the second cover are placed inside the first main body, but structural separation may occur due to the use of two main bodies and two or more cover parts. Separation can lead to damage to the contents during the delivery process, so a structure is needed to prevent this problem.

For this purpose, a first convex concave-convex portion that can be coupled to the first concave groove of the second cover portion is formed on the upper side of the second body portion. In addition, in order to further strengthen this structural stability, a third convex and convex portion is formed on the second cover portion, protruding in a direction from the second cover portion toward the first concave groove portion. The third cover part is intended to increase coupling force by reducing the space between the second cover part and the second main body part, and is preferably formed in a flat structure.

In addition, as described above, in order to solve the problem that structural separation may occur due to the use of two main bodies and two or more cover parts, as shown in Figures 2 and 5, a first body is installed on the side of the second main body. A second concave groove is formed to which the second convex and convex portion formed on the side of the main body can be coupled.

In this way, the first convex and convex portion and the first concave groove are coupled in the vertical direction to prevent the second main body from shaking left and right inside the first main body, and the second convex and concave and convex portion are combined with the second concave groove in the left and right directions. By preventing the second main body from shaking up and down inside the first main body, three-dimensional structural stability can be secured by preventing shaking in the horizontal and vertical axes.

Figure 6 is a diagram showing the process of inserting the electronic paper display panel into the fixing part according to an embodiment of the present invention, and Figure 7 is a diagram showing the process of separating the second cover part from the first body part according to an embodiment of the present invention. 8 is a diagram showing a structure for preventing slipping in the process of loading a packaging system including an electronic paper display panel according to an embodiment of the present invention.

The fixing part is formed so that the e-paper display panel is inserted into the fixing part, and further includes fixing reinforcement parts that strengthen the fixing force at both ends of the e-paper display panel after insertion, and the second body part and the second cover. It is preferable that at least two of the four corners of the second cover part have a chamfer structure so that the second cover part can be easily separated from the first main body part when the second cover part is coupled to the first main body part.

As shown in Figures 6(D) and (E), the electronic paper display panel is inserted so that it can be stored in the fixing part, and then, as shown in Figure 6(F), the electronic paper display panel is inserted through the fixing reinforcement parts on both sides of the fixing part during the delivery process. It strengthens the fixing force so that the paper display panel does not fall out of the fixing part. It is preferable to use bolts as fixed reinforcement parts.

As shown in Figure 7(G), a moving auxiliary unit 230 is formed so that the delivery engineer can hold the packaging for delivery. The delivery driver can deliver the goods by holding this moving auxiliary unit. FIG. 7(I) is a diagram showing a cross section along the x-y line of FIG. 7(H). Since the second main body and the second cover arranged inside the first main body have a structure with enhanced stability as described above, in some cases, in order to take out the goods after delivery, the second cover is separated from the first main body. It may not be easy to separate. In order to solve this problem, it is preferable to chamfer the edges of the second cover part as shown in (H) and (I) of Figure 7. This structure makes it easy for the user to separate the second cover part from the first body part through the chamfered structure, as shown in (J) of FIG. 7. Additionally, in addition to this chamfer structure, it is preferable to further form a gripping part on the second cover part to separate the second cover part so that the second cover part can be held by hand, as shown in (J) of FIG. 7.

The storage portion formed on the upper surface is for storing the upper packaging when the packaging according to the present invention is loaded, as shown in FIG. 8. The upper packaging is placed in the receiving part formed on the upper surface of the first cover part of the lower packaging. At this time, if the bottom of the upper packaging is in close contact with the receiving part of the lower packaging, it is not easy to separate the packaging later. It won't happen. In order to prevent this, as shown in Figure 8 (L), the bottom surface of all packaging is not completely flat so that the bottom surface of the upper packaging does not come into close contact with the receiving part of the lower packaging, but the corners are protruded to allow air to move inside. It is desirable to create a space where

The first body part, the first cover part, and the third cover part are each made of polypropylene (PP), polystyrene (PS), polyethylene (PE), polycarbonate (PC), or acrylonitrile butadiene. It is preferable that it contains one of styrene (ABS, Acrylonitrile Butadiene Styrene), and most preferably, it is composed of polypropylene (PP, polypropylene) as the main component.

Polypropylene (PP, polypropylene) is a polymer of propylene and has excellent chemical resistance, mechanical properties, and thermal properties. When propylene, which is obtained in abundance from natural gas and is similar to ethylene and has one more carbon atom, is polymerized, it is more transparent and resistant to refraction than polyethylene. Polypropylene is made.

Polystyrene (PS) is an amorphous polymer obtained by radical polymerization of styrene and is a colorless and transparent thermoplastic resin. The boiling point is 145°C, and it is also called styrole resin. It is made of polystyrene, a polymer of liquid styrene units created by reacting ethylene and benzene, and is not easily corroded by chemicals. Styrene resin is the easiest to process among plastics and has a high refractive index. In addition, it is not only transparent and beautiful in color, but also forms a solid molded product and is excellent as an electrical insulating material.

Polyethylene (PE.polyethylene) is a polymer obtained by polymerizing ethylene as a monomer. It is one of the synthetic polymers called polyolefin, and along with polypropylene, it is the product with the highest production volume worldwide.

Polycarbonate (PC, Polycarbonate) belongs to engineering plastics and has particularly high impact strength due to its toughness. It has high heat resistance, good low-temperature characteristics (135~-100℃), is stable to light, and has little oxidation during processing. It has excellent electrical properties, is transparent, has good dimensional stability and weather resistance, has low water absorption, is non-toxic, and is resistant to water and strong acids. It is widely used in electrical parts, mechanical parts, daily necessities (food, gas lighters, cosmetic containers), and security helmets.

Acrylonitrile Butadiene Styrene (ABS) is a copolymer obtained by polymerizing acrylonitrile (AN), butadiene, and styrene. It is a light ivory-colored solid that is easy to color, has good surface gloss, and has mechanical and electrical properties. Due to its excellent properties and chemical resistance, it is mainly used as a surface material for home and office electronic products and automobiles.

The second body portion and the second cover portion are each made of expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyethylene (EPE), or expanded polyolefine (EPO). It is preferable to include expanded polypropylene (EPP, expanded polypropylene) as the main ingredient.

Expanded polypropylene (EPP) is a cutting-edge material used in automobile parts, packaging materials, construction materials, and insulation materials. It has excellent brittleness, flexibility, and chemical resistance, making it suitable for increasing the stability of product packaging and miniaturizing the volume. Expanded polystyrene (EPS) is made by adding a foaming agent to polystyrene and extruding it to create a low-foaming disc. This disc is then heated on both sides in the air to increase the degree of foaming. Expanded polystyrene has high thermal insulation properties because it forms a single foam, and its density is low, making it more robust. Taking advantage of these characteristics, expanded polystyrene is widely used in insulating containers (fish packaging boxes, etc.), cushioning materials for fragile devices, and food plates.

Figure 9 is a diagram showing an electronic paper display panel according to an embodiment of the present invention.

The packaging system including the electronic paper display panel according to the present invention includes an electronic paper display panel capable of displaying delivery information and a fixing unit capable of accommodating and fixing the electronic paper display panel.

The e-paper display panel includes an upper case, a first form disposed between the upper case and the display panel, tempered glass, a display panel, a second foam disposed between the display panel and the PCB board, along the direction from top to bottom, It may include a PCB board, a third foam disposed between the upper case and the lower case, a lower case, a fourth foam disposed between the lower case and the battery cover, and a battery cover.

The reason for including an electronic paper display panel in the present invention is to replace existing paper invoices. In the case of paper invoices, they were often damaged during transportation, and were particularly vulnerable to moisture, so there was a problem that the contents of the invoice could not be confirmed when wet. In order to prevent this, the electronic paper display panel is used as an invoice and has the same configuration as the present invention to prevent damage during transportation. The first to fourth forms are used to prevent the risk of damage that may occur due to separation or impact between parts, and it is desirable to form four forms between each part.

When information about the delivered item is transmitted from the control center's server to the manager's terminal, the manager's terminal tags the electronic paper display panel (EPD) through NFC, and the item information received from the control center's server is stored in the delivered item. . The information stored in this way is communicated with the delivery driver's terminal through Bluetooth, making it possible to collect necessary information during delivery.

Packaging The packaging may include a temperature sensor that detects temperature, a humidity sensor that detects humidity, and an acceleration sensor that detects an impact applied to the packaging. Packaging The packaging includes a data logger, and the data logger includes a temperature sensor for detecting temperature, a humidity sensor for detecting humidity, and an acceleration sensor for detecting an impact applied to the packaging.

The data logger measures the temperature, humidity, and impact of the packaging through temperature sensors, humidity sensors, and acceleration sensors, and transmits them to the manager server through the delivery terminal, thereby managing the status of the packaging.

Since data loggers receive wireless power supply such as batteries, there is a need to save power. In other words, in order for the sensor to be activated while the power to the data logger is supplied, the acceleration sensor can detect the amount of impact applied to the data logger and activate the data logger.

The data logger includes a dedicated gateway, a microcontroller unit (MCU) that drives the data logger and controls its operation, a display unit for displaying the status of the data logger, and a power supply unit that supplies driving power to the data logger. It is desirable. The data logger can start operation when a power switch is pressed using the power unit or an impact of a certain intensity or higher is detected through the acceleration sensor installed in the sensor unit.

The operating states of the data logger can be divided into sleep, standby, start, and delivery. It switches from sleep mode to the start state according to an activation command using the administrator's terminal, and at this time, delivery information can be recorded. When you instruct delivery to start after recording delivery information, data corresponding to environmental information (temperature, humidity, illuminance, and impact) is collected and received as delivery status, and when abnormalities in temperature or impact are detected, a warning sign and a warning sound are output. In the delivery complete state, the collected data is transferred to the cloud server and then changed to sleep mode as a termination instruction.

The microcontroller unit (MCU) is a processor for controlling the system and is responsible for controlling various functions of the data logger. The display unit includes at least two light emitting diodes (LEDs) with different wavelengths of ultraviolet rays. For example, using a light emitting diode (LED) that produces two colors, red and green, when a battery (wireless power source) is installed, the green diode blinks for about 10 seconds, and then reduces current consumption. The green diode turns off. Afterwards, when connected to the delivery driver's terminal, the green light-emitting diode is turned on for 10 seconds, and then the green diode is turned off again to reduce current consumption. In addition, when the temperature and humidity detected by the sensor are outside the preset temperature and humidity range, or when the cover of the packaging is opened through the illuminance sensor, the red light-emitting diode may be turned on.
