Description

Technical Field

[0001] This invention relates to the field of fruit preservation cardboard box technology, specifically a fruit preservation cardboard box and a method for preserving, storing, and transporting fruit. Background Technology

[0002] Fruit preservation and storage is a process that uses scientific methods and technologies to extend the shelf life of fruits while maintaining their original quality and flavor to better meet market and consumer demands. This includes the scientific preservation of fresh fruits to extend their shelf life, maintain their freshness and nutritional value, reduce spoilage, and improve their quality and market competitiveness. Fruit preservation cartons are commonly used for packaging fruits.

[0003] Fruit preservation cartons are environmentally friendly boxes designed to protect fruits and vegetables, resisting pressure and reducing microbial contamination to keep them fresh. Made from environmentally friendly materials, these cartons better meet modern consumer demands for environmental protection. They effectively maintain the freshness of fruits and vegetables, reducing moisture loss and microbial contamination. With excellent pressure resistance, they protect fruits and vegetables during transportation and storage, minimizing mechanical damage.

[0004] Because ordinary fruit preservation boxes directly hold the fruit, there is direct contact between the fruit and between the fruit and the box. Therefore, during transportation, if the fruit is bumped or jostled, the fruit will be squeezed against each other, resulting in a higher rate of spoilage and making the transport of fruit less efficient. Summary of the Invention

[0005] The purpose of this invention is to provide a fruit preservation cardboard box and a method for preserving and transporting fruit, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A fruit preservation cardboard box includes an outer box and an inner box disposed inside the outer box; both sides of the outer box and the inner box are fixedly installed with a horizontal cover plate and a vertical cover plate. The inner box is provided with a layered board for dividing the space inside the inner box into multiple layers. The layered board is provided with multiple longitudinal partitions and transverse partitions. The longitudinal partitions and transverse partitions are crisscrossed to divide the layered board into multiple storage chambers. The storage chambers are provided with multiple buffer structures to reduce the damage to the fruit caused by collisions and compression.

[0007] As a further aspect of the present invention: a plurality of first snap-fit ​​grooves are provided on one side of the longitudinal partition plate in the vertical direction, and a second snap-fit ​​groove is provided on the side of the transverse partition plate away from the first snap-fit ​​grooves, and the first snap-fit ​​grooves and the second snap-fit ​​grooves cooperate with each other.

[0008] As a further embodiment of the present invention: the layered plate is provided with a plurality of longitudinal fitting grooves that can engage with the longitudinal partition plate, and a transverse fitting groove that can engage with the transverse partition plate.

[0009] As a further embodiment of the present invention: the buffer structure includes a plurality of trapezoidal cardboard pieces fixedly installed on the transverse partition plate and the longitudinal partition plate, wherein the trapezoidal cardboard pieces are provided with slots and limiting slots.

[0010] As a further embodiment of the present invention: the inner box body is provided with a first fitting groove that slides and engages with both the longitudinal partition plate and the transverse partition plate.

[0011] As a further embodiment of the present invention: a first wavy protrusion is fixedly installed on the side of the outer box close to the inner box, and a second wavy protrusion is fixedly installed on the side of the inner box close to the outer box, the first wavy protrusion and the second wavy protrusion are misaligned and fixedly installed; paper pillars are fixedly installed at the corners of the outer box and the inner box.

[0012] As a further embodiment of the present invention: the outer casing is provided with a vent hole that penetrates the inner casing, and both the transverse partition plate and the longitudinal partition plate are provided with air grooves that communicate with the vent hole.

[0013] As a further aspect of the present invention: the outer surfaces of the longitudinal partition, the transverse partition, and the layered plate are all coated with O2 absorbent, CO2 absorbent, ethylene absorbent, moisture absorbent, and other agents used for preservation.

[0014] A method for preserving and transporting fruit using fruit preservation cartons as described above: Step 1: First, close the horizontal cover on the bottom of the carton, then close the vertical cover on the bottom of the carton, and seal it with tape. Step 2: Place the shelf flat inside the carton, and then fit the horizontal and vertical dividers into the shelf and the inner box to form multiple storage compartments.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0026] Please see Figures 1-7 In this embodiment of the invention, a fruit preservation cardboard box includes an outer box 1 and an inner box 2 disposed inside the outer box 1; a horizontal cover plate 7 and a vertical cover plate 8 are fixedly installed on both sides of the outer box 1 and the inner box 2 in the vertical direction. The inner box 2 is provided with a layered board 4 for dividing the space inside the inner box 2 into multiple layers. The layered board 4 is provided with multiple longitudinal partitions 5 and transverse partitions 6. The longitudinal partitions 5 and transverse partitions 6 are crisscrossed to divide the layered board 4 into multiple storage chambers 11. The storage chambers 11 are provided with multiple buffer structures to reduce the damage to the fruit caused by collision and compression.

[0027] In this embodiment, the outer box 1, the inner box 2, the transverse cover 7, and the longitudinal cover 8 are all made of paper. The transverse cover 7 and the longitudinal cover 8 can be freely rotated by the pattern, thereby realizing the opening and closing of the carton.

[0028] The layered panel 4 can divide the space inside the inner box 2 into multiple independent spaces that are separated vertically, so as to prevent the fruits in the upper and lower spaces from affecting each other and thus affecting the control of fruit ripening. In addition, the layered panel 4 can indirectly increase the area of ​​the fruit's weight acting on the horizontal cover 7 and the vertical cover 8 on the lower side of the carton, which can effectively improve the load-bearing capacity of the carton and reduce the probability of the fruit falling off the bottom of the carton.

[0029] The crisscrossing horizontal partitions 6 and vertical partitions 5 form multiple storage compartments 11. After the fruit is placed in the storage compartments 11, the horizontal partitions 6 and vertical partitions 5 can prevent the fruit from contacting each other. Since the number of storage compartments 11 on each partition 4 is fixed, the number of fruit in a carton can be effectively controlled. The multiple buffer structures in the storage compartments 11 can contact the fruit from multiple directions. During handling and transportation, the buffer structures can reduce the impact of vibration on the fruit and effectively prevent the fruit from colliding and squeezing with each other, thus reducing the transportation loss rate.

[0030] As a further embodiment of the present invention, a plurality of first snap-fit ​​grooves 501 are provided on one side of the vertically upward-facing longitudinal partition plate 5, and a second snap-fit ​​groove 601 is provided on the side of the transverse partition plate 6 away from the first snap-fit ​​grooves 501, and the first snap-fit ​​grooves 501 and the second snap-fit ​​grooves 601 cooperate with each other.

[0031] In this embodiment, the length of the first snap-fit ​​groove 501 is half the width of the longitudinal divider 5, and the length of the second snap-fit ​​groove 601 is half the width of the transverse divider 6 and the same as the length of the first snap-fit ​​groove 501. Through the interlocking of the first snap-fit ​​groove 501 and the second snap-fit ​​groove 601, the transverse divider 6 can be vertically installed on the longitudinal divider 5, and each end face of the transverse divider 6 in the width direction is located on the same horizontal plane as each end face of the longitudinal divider 5 in the width direction. This is beneficial for reasonable control of the reasonable layering of the vertical space inside the carton. By using the interlocking of multiple transverse dividers 6 and longitudinal dividers 5, multiple rectangular spaces can be formed.

[0032] As a further embodiment of the present invention, the layered plate 4 is provided with a plurality of longitudinal fitting grooves 401 that can engage with the longitudinal partition plate 5, and a transverse fitting groove 402 that can engage with the transverse partition plate 6.

[0033] In this embodiment, the longitudinal interlocking groove 401 can be engaged with the longitudinal partition plate 5, and the transverse interlocking groove 402 can be engaged with the transverse partition plate 6. The entire assembly formed by the interlocking of multiple transverse partition plates 6 and longitudinal partition plates 5 is inserted into the longitudinal interlocking groove 401 and transverse interlocking groove 402 on the layered plate 4, so that the rectangular space and the layered plate 4 form a storage room 11, which can effectively isolate the fruits from each other, avoid the fruits from affecting each other, and help control the ripeness of the fruits.

[0034] As a further embodiment of the present invention, the buffer structure includes a plurality of trapezoidal cardboard 9 fixedly installed on the transverse partition 6 and the longitudinal partition 5, wherein the trapezoidal cardboard 9 is provided with a slot 901 and a limiting slot 902.

[0035] In this embodiment, the shorter bottom surface of the trapezoidal cardboard 9 is made of a relatively soft material, which can deform under the pressure of the fruit, thereby increasing the contact area between the trapezoidal cardboard 9 and the fruit. The two inclined sides of the trapezoidal cardboard 9 are made of a relatively hard material with a certain degree of elasticity. After the fruit is placed in the storage chamber 11, the outer surface of the fruit can contact the shorter bottom surface of the trapezoidal cardboard 9, thereby squeezing the trapezoidal cardboard 9 and causing it to bend and deform. At this time, the width of the groove 901 will become smaller, so that the trapezoidal cardboard 9 can better wrap around the fruit, thereby increasing the buffering range of the cushioning structure. When encountering vibration, the fruit will shake in the storage chamber 11. At this time, the two inclined sides of the trapezoidal cardboard 9 with a certain degree of elasticity will use their elasticity to buffer the force generated by the shaking of the fruit, thereby reducing the impact of vibration on the fruit and effectively preventing the fruit from colliding and squeezing with each other, thus reducing the transportation loss rate.

[0036] The limiting groove 902 can restrict the vertical displacement of the fruit, which can greatly reduce the damage caused by the fruit colliding with the layered plate 4 due to severe vibration.

[0037] As a further embodiment of the present invention, the inner box 2 is provided with a first fitting groove 202 that slides and engages with both the longitudinal partition plate 5 and the transverse partition plate 6.

[0038] In this embodiment, the bottom layer board 4 is first placed flat in the carton. Then, the entire assembly formed by interlocking multiple horizontal partition boards 6 and vertical partition boards 5 is inserted into the layer board 4. During the interlocking process, the horizontal partition boards 6 and vertical partition boards 5 will enter the first fitting groove 202. The first fitting groove 202 can fix the position of the horizontal partition boards 6 and vertical partition boards 5 to prevent the storage room 11 from shrinking and damaging the fruit.

[0039] As a further embodiment of the present invention, a first wavy protrusion 101 is fixedly installed on the side of the outer box 1 near the inner box 2, and a second wavy protrusion 201 is fixedly installed on the side of the inner box 2 near the outer box 1. The first wavy protrusion 101 and the second wavy protrusion 201 are misaligned and fixedly installed; a paper column 3 is fixedly installed at the corner of the outer box 1 and the inner box 2.

[0040] In this embodiment, the first wavy protrusion 101 and the second wavy protrusion 201 can effectively improve the folding resistance of the outer box 1 and the inner box 2 in the lateral direction, and can prevent the carton from bending and deforming under excessive pressure, thus losing its ability to protect the fruit; the paper column 3 has relatively high strength, which can further improve the compression resistance of the carton and improve the carton's ability to protect the fruit.

[0041] As a further embodiment of the present invention, the outer casing 1 is provided with a vent hole 10 that penetrates the inner casing 2, and both the transverse partition plate 6 and the longitudinal partition plate 5 are provided with air grooves 12 that communicate with the vent hole 10.

[0042] In this embodiment, the air vents 10 and air channels 12 allow the air inside the carton to circulate, preventing the fruit from ripening too quickly due to excessive CO2 concentration inside the carton, thus effectively controlling the ripeness of the fruit.

[0043] As a further embodiment of the present invention, the outer surfaces of the longitudinal partition plate 5, the transverse partition plate 6, and the layered plate 4 are all coated with O2 absorbent, CO2 absorbent, ethylene absorbent, moisture absorbent, and other agents used for preservation.

[0044] In this embodiment, preservatives such as O2 absorbent, CO2 absorbent, ethylene absorbent, and moisture absorbent can effectively reduce the ripening reaction of fruit inside the cardboard box, thereby achieving fruit preservation.

[0045] A method for preserving and transporting fruit using the fruit preservation cardboard boxes described above includes the following steps: Step 1: First, close the horizontal cover 7 on the bottom of the carton, then close the vertical cover 8 on the bottom of the carton, and seal it with tape. Step 2: Place the layered board 4 flat inside the carton, and then fit the horizontal partition board 6 and the vertical partition board 5 into the layered board 4 and the inner box 2 in sequence to form multiple storage compartments 11. Step 3: Place the fruit in storage compartment 11 and make it come into contact with the buffer structure; Step 4: Repeat steps 2 and 3 to fill the carton; close the horizontal cover 7 on the top of the carton, close the vertical cover 8 and seal it with tape; Step 3: Neatly stack the cardboard boxes containing the fruit and control external interference factors such as ambient air temperature and humidity.
