[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 in order to better meet market and consumer demands. This includes scientific preservation of fresh fruits to extend the shelf life of fruits while maintaining their freshness and nutritional value, reducing losses, and improving the quality and market competitiveness of fruits. Fruit preservation cartons are often used to pack fruits.

[0003] ‌Fruit preservation cartons are environmentally friendly cartons that protect fruits and vegetables, resist pressure, and reduce microbial contamination, keeping fruits and vegetables fresh. Fruit preservation cartons are made of environmentally friendly materials, which better meet the modern people's demand for environmental protection. They can effectively maintain the freshness of fruits and vegetables, reduce water loss and microbial contamination. They have good pressure resistance, can protect fruits and vegetables during transportation and storage, and reduce mechanical damage.

[0004] Since ordinary fruit preservation cartons are used to directly hold fruits, there is direct contact between the fruits and between the fruits and cartons. Therefore, if there is bumps during transportation, the fruits will squeeze each other, which will increase the transportation loss rate and is not conducive to the transportation of fruits. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0026] See also Figure 1 to Figure 7 In an embodiment of the present invention, a fruit preservation paper box includes an outer box body 1 and an inner box body 2 arranged in the outer box body 1; both sides of the outer box body 1 and the inner box body 2 in the vertical direction are fixedly installed with a horizontal cover plate 7 and a longitudinal cover plate 8; The inner box body 2 is provided with a layering plate 4 for dividing the space inside the inner box body 2 into multiple layers, and the layering plate 4 is provided with multiple longitudinal partitions 5 and transverse partitions 6. The longitudinal partitions 5 and the transverse partitions 6 are crisscrossed to divide the layering plate 4 into multiple storage chambers 11, and the storage chambers 11 are provided with multiple buffer structures for reducing damage to fruits caused by collision and squeezing.

[0027] In this embodiment, the outer box body 1 and the inner box body 2 as well as the transverse cover plate 7 and the longitudinal cover plate 8 are all made of paper, and the free rotation of the transverse cover plate 7 and the longitudinal cover plate 8 can be achieved by arranging patterns, thereby realizing the opening and closing of the carton.

[0028] The layering plate 4 can divide the space in the inner box body 2 into a plurality of independent spaces isolated from each other, so as to prevent the fruits in the upper and lower spaces from influencing each other and affecting the control of the maturity of the fruits; and the layering plate 4 can indirectly increase the effective area of ​​the fruit gravity acting on the horizontal cover plate 7 and the longitudinal cover plate 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 from the bottom of the carton.

[0029] A plurality of storage chambers 11 are formed between the criss-crossed transverse partitions 6 and the longitudinal partitions 5. After placing the fruits in the storage chambers 11, the transverse partitions 6 and the longitudinal partitions 5 can prevent the fruits from contacting each other. Since the number of storage chambers 11 on each layered plate 4 after separation is certain, the number of fruits in a carton can be effectively controlled; the plurality of buffer structures in the storage chambers 11 can contact the fruits from multiple directions. During handling and transportation, the buffer structures can reduce the impact of vibration on the fruits, effectively avoid collision and squeezing of the fruits, and reduce the transportation loss rate.

[0030] As a further solution of the present invention, a plurality of first snap-in grooves 501 are provided on the vertical side of the longitudinal partition plate 5, and a second snap-in groove 601 is provided on the side of the transverse partition plate 6 away from the first snap-in groove 501, and the first snap-in groove 501 cooperates with the second snap-in groove 601.

[0031] In this embodiment, the length of the first snap-in groove 501 is half the width of the longitudinal partition plate 5, and the length of the second snap-in groove 601 is half the width of the transverse partition plate 6, and is the same as the length of the first snap-in groove 501. By mutual snap-in connection between the first snap-in groove 501 and the second snap-in groove 601, the transverse partition plate 6 can be vertically installed on the longitudinal partition plate 5, and each end surface of the transverse partition plate 6 in the width direction and each end surface of the longitudinal partition plate 5 in the width direction are located on the same horizontal plane; this is conducive to reasonable control of the reasonable stratification of the vertical space in the carton; by utilizing the mutual snap-in connection between multiple transverse partition plates 6 and the longitudinal partition plates 5, multiple rectangular spaces can be formed.

[0032] As a further solution of the present invention, the layered plate 4 is provided with a plurality of longitudinal engaging grooves 401 which can be engaged with the longitudinal partition plate 5 , and a plurality of transverse engaging grooves 402 which can be engaged 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 whole formed by the mutual engagement between multiple transverse partition plates 6 and the longitudinal partition plate 5 is engaged into the longitudinal interlocking groove 401 and the transverse interlocking groove 402 on the layering plate 4, so that the rectangular space and the layering plate 4 form a storage chamber 11, which can effectively isolate the fruits from each other, avoid mutual influence between the fruits, and is conducive to the control of the maturity of the fruits.

[0034] As a further solution of the present invention, the buffer structure includes a plurality of trapezoidal paperboards 9 fixedly mounted on the transverse partition plate 6 and the longitudinal partition plate 5 , and the trapezoidal paperboards 9 are provided with notches 901 and limiting grooves 902 .

[0035] In this embodiment, the material of the shorter bottom surface of the trapezoidal paperboard 9 is relatively soft and can be deformed with the squeezing of the fruit, so that the contact area between the trapezoidal paperboard 9 and the fruit is increased; and the material of the two oblique sides of the trapezoidal paperboard 9 is relatively hard and has a certain 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 paperboard 9, thereby squeezing the trapezoidal paperboard 9 to bend and deform it, and at this time the width of the notch 901 will become smaller, so that the trapezoidal paperboard 9 can better wrap the fruit to increase the buffering range of the buffering structure; when encountering vibration, the fruit will shake in the storage chamber 11, and at this time, the two oblique sides of the trapezoidal paperboard 9 with a certain elastic force will use the elastic force to buffer the force generated by the shaking of the fruit, thereby reducing the impact of the vibration on the fruits, which can effectively avoid the collision and squeezing of the fruits, and reduce the transportation loss rate.

[0036] The limiting groove 902 can limit the vertical displacement of the fruit, which can greatly reduce the damage caused by the collision between the fruit and the layering plate 4 due to severe vibration.

[0037] As a further solution of the present invention, the inner box body 2 is provided with a first engaging groove 202 which is slidably matched with the longitudinal partition plate 5 and the transverse partition plate 6 .

[0038] In this embodiment, the bottom layer plate 4 is first placed flat in the carton, and then a plurality of transverse partition plates 6 and longitudinal partition plates 5 are clipped together to form a whole which is clipped onto the layer plate 4. During the clipping process, the transverse partition plates 6 and longitudinal partition plates 5 will enter the first interlocking groove 202. The positions of the transverse partition plates 6 and longitudinal partition plates 5 can be fixed through the first interlocking groove 202 to prevent the space of the storage chamber 11 from becoming smaller and squeezing and damaging the fruit.

[0039] As a further solution of the present invention, a first wavy protrusion 101 is fixedly installed on a side of the outer box body 1 close to the inner box body 2, and a second wavy protrusion 201 is fixedly installed on a side of the inner box body 2 close to the outer box body 1, and the first wavy protrusion 101 and the second wavy protrusion 201 are staggered and fixedly installed; paper columns 3 are fixedly installed at the corners on the outer box body 1 and the inner box body 2.

[0040] In this embodiment, the first wavy protrusions 101 and the second wavy protrusions 201 can effectively improve the lateral bending resistance of the outer box body 1 and the inner box body 2, and can prevent the carton from bending and deforming when the pressure is too high, thereby losing its ability to protect the fruit; the strength of the paper column 3 is relatively high, which can further improve the compression resistance of the carton and improve the carton's ability to protect the fruit.

[0041] As a further solution of the present invention, the outer box body 1 is provided with an air hole 10 penetrating the inner box body 2 , and the transverse partition plate 6 and the longitudinal partition plate 5 are both provided with an air groove 12 communicating with the air hole 10 .

[0042] In this embodiment, the air in the carton can be kept in a circulating state through the air holes 10 and the air grooves 12, thereby preventing the fruit from being saturated due to the CO in the carton. 2 The concentration is too high and the ripening is accelerated, which can effectively control the maturity of the fruit.

[0043] As a further solution 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 O 2 Absorbent, CO 2 Absorbents, ethylene absorbents, moisture absorbents and other agents used for preservation.

[0044] In this embodiment, O 2 Absorbent, CO 2 Absorbents, ethylene absorbers, moisture absorbers and other agents used for preservation can effectively reduce the ripening reaction of fruits in cartons, thereby preserving the fruits.

[0045] A method for preserving and storing fruits using the above-mentioned fruit preservation paper box comprises the following steps: Step 1: First close the transverse cover plate 7 on the lower side of the carton, then close the longitudinal cover plate 8 on the lower side of the carton, and seal them with tape; Step 2: Place the layering plate 4 flatly into the carton, and then sequentially fit the transverse partition plate 6 and the longitudinal partition plate 5 into the layering plate 4 and the inner box body 2 to form a plurality of storage chambers 11; Step 3: Put the fruit into the storage chamber 11 and make it contact with the buffer structure; Step 4: Repeat steps 2 and 3 to fill the carton completely; close the transverse cover plate 7 on the upper side of the carton, close the longitudinal cover plate 8 and seal them with tape; Step 3: Stack the cartons containing fruits neatly and control external interference factors such as outside air temperature and humidity.
