When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0059] The utility model provides a soft film layer structure.

[0060] See also Figure 1 In one embodiment of the present invention, the soft film layer structure includes:

[0061] A soft film layer 30 , wherein a plurality of receiving grooves 33 and a plurality of overhead protrusions 32 are integrally formed on the soft film layer 30 , and a first ventilating portion 34 is provided on the receiving groove 33 ;

[0062] The opening direction of the receiving groove 33 is the same as or opposite to the opening direction of the overhead protruding groove 32 .

[0063] It is understandable that the soft film layer 30 is arranged in the packaging portion. In order to carry as many strawberries as possible, the soft film layer 30 is spread flat in the packaging portion, so that the edge of the soft film layer 30 is adapted to the inner wall contour of the packaging portion.

[0064] Preferably, the packaging portion is in a rectangular parallelepiped structure, and the edge contour of the soft film layer 30 is a rectangle adapted to the rectangular parallelepiped structure.

[0065] In some embodiments, the packaging portion is circular, polygonal or other structures, and the edge contour of the soft film layer 30 is adapted to the shape of the circular, polygonal or other structures. Therefore, the edge contour of the soft film layer 30 is not described here one by one.

[0066] It should be noted that, in order to maximize the use of the area of ​​the soft film layer 30 to receive more strawberries, a plurality of receiving grooves 33 are distributed in an array on the soft film layer 30 .

[0067] like Figure 1As shown, the soft film layer 30 includes a soft film body 31 , and the receiving groove 33 is concavely formed toward one side of the soft film body 31 , and the receiving groove 33 is used to accommodate strawberries. Thus, the contour shape of the receiving groove 33 is similar to the contour of the strawberry.

[0068] It can be understood that in order to improve the adaptability between the receiving groove 33 and the strawberries, the contour of the receiving groove 33 is designed to fit the shape of the strawberries, so that when the strawberries are placed in the receiving groove 33, the outer surface of the strawberries can fit on the side walls of the receiving groove 33, thereby reducing the possibility of the strawberries being displaced relative to the receiving groove 33 during transportation, thereby reducing the probability of collision between the strawberries and the receiving groove 33, and improving the protection effect and quality of the strawberries.

[0069] like Figure 1 As shown, the overhead convex groove 32 is provided on the soft film body 31 , and the overhead convex groove 32 is formed on the soft film body 31 to be concave toward one side.

[0070] It can be understood that a plurality of the overhead convex grooves 32 are arranged on the soft film body 31, and some of the overhead convex grooves 32 are arranged between multiple receiving grooves 33, so as to increase the structural strength of the soft film body 31 itself, avoid the possibility of collapse of the soft film body 31, and improve the structural strength of the soft film body 31.

[0071] It should be noted that in order to ensure the protection effect of strawberries while controlling costs, the soft film layer adopts a high-soft PE mold, combined with the arrangement of multiple overhead grooves 32, which can ensure the protection effect of strawberries and prevent them from being damaged, and can also improve the structural strength of the soft film layer 30. It does not need to be integrally molded with the packaging box, thereby reducing costs.

[0072] In one embodiment, the soft film layer 30 is provided in one layer, so that when the soft film layer 30 is provided in the packaging portion, the supporting legs in the packaging portion abut against the overhead protrusion 32 to achieve support for the soft film layer 30 .

[0073] It can be understood that after the soft film layer 30 supporting the strawberries is supported by the supporting legs, the soft film layer 30 is isolated from the packaging part, thereby preventing the soft film layer 30 from directly hitting the packaging part when subjected to vibration or impact, thereby affecting the quality of the strawberries.

[0074] It should be noted that in order to prevent the strawberries from falling off the soft film layer 30 when placed on the single layer of the soft film layer 30, after the strawberries are placed on the single layer of the soft film layer 30, the surface of the soft film layer 30 is covered with plastic wrap to confine the strawberries in the receiving groove 33, thereby improving the confinement effect on the strawberries.

[0075] It is understandable that in order to improve the air permeability of the soft film layer 30 after being covered with the plastic wrap, holes are opened in the plastic wrap after being covered with the plastic wrap.

[0076] In some embodiments, the soft film layer 30 is provided with two layers, and the two layers of the soft film layers 30 are arranged opposite to each other, so that the receiving grooves 33 on the two layers of the soft film layers 30 are arranged opposite to each other one by one, thereby facilitating the placement of strawberries in the receiving grooves 33.

[0077] It should be noted that, in order to ensure the wrapping and protective effect on the strawberries, the two soft film layers 30 are adhered to each other, so that the enclosed space formed by the two receiving grooves 33 can fully wrap the strawberries.

[0078] It can be understood that when the opening direction of the receiving groove 33 of the two layers of the soft film layers 30 is the same as the opening direction of the overhead convex groove, the two soft film layers 30 are fitted together, and the receiving grooves on the two soft film layers 30 are relatively arranged, and the openings of the overhead convex grooves 32 on the two soft film layers 30 are relatively arranged, thereby avoiding the setting of the overhead convex groove 32 interfering with the fitting of the two layers of the soft film layers 30, thereby ensuring the protection effect on the strawberries.

[0079] It can be understood that when the opening direction of the receiving groove 33 of one soft film layer 30 is the same as the opening direction of the overhead convex groove, and the opening direction of the receiving groove 33 of the other soft film layer 30 is opposite to the opening direction of the overhead convex groove, when the two soft film layers 30 are bonded together, the overhead convex groove 32 on one soft film layer 30 is inserted into the overhead convex groove 32 on the other soft film layer 30, so as to ensure the bonding of the two soft film layers 30 and thus ensure the protection effect on the strawberries.

[0080] It should be noted that when the number of the soft film layers 30 is greater than two, the two soft film layers 30 form a group and the redundant single soft film layer 30 can be a group alone, or each soft film layer 30 can be a group, so that multiple groups of soft film layers 30 are arranged side by side in the packaging part.

[0081] In order to ensure air circulation in the receiving groove 33, a first air permeable portion 34 is provided on the receiving groove 33. When the soft film layer 30 is provided in the packaging box, the provision of the first air permeable portion enables the receiving groove 33 to communicate with the internal space of the packaging box. Through the flow exchange of air, the air permeability of the receiving groove 33 is improved, the shelf life of the strawberries is extended, and the transportation quality of the strawberries is improved.

[0082] like Figure 1 As shown, the first ventilation portion 34 is in a hole shape, and a plurality of ventilation holes are provided on the receiving groove 33 .

[0083] It can be understood that when the soft film layer 30 is placed in the packaging part, the multiple first air permeable parts 34 are used to achieve gas exchange between the receiving groove 33 and the internal space of the packaging part, thereby improving the air permeability of the strawberries placed on the soft film layer 30 and preventing the strawberries from rotting due to air permeability problems.

[0084] Furthermore, if Figure 17 As shown, the first ventilation portion 34 is in a strip shape, so that while ensuring the ventilation performance of the receiving groove 33, the arrangement of the strip-shaped ventilation holes facilitates its processing and reduces the processing difficulty.

[0085] The technical solution of the present invention reduces the difficulty of processing the soft film layer 30 by integrally forming a plurality of the receiving grooves 33 and a plurality of overhead convex grooves 32 on the soft film layer 30, which is beneficial to improving the production efficiency of the soft film layer 30 and eliminating the need for integral molding with the packaging box to reduce costs. In addition, a plurality of overhead convex grooves 32 are provided on the soft film layer 30, and some of the overhead convex grooves 32 are provided between a plurality of the receiving grooves 33. In this way, effective shock absorption protection for strawberries is achieved through the soft soft film layer 30, while also ensuring the structural strength of the soft film layer 30, thereby preventing the soft film layer 30 from collapsing when carrying strawberries and affecting the bearing stability. At the same time, the overhead convex grooves 32 between the plurality of the bearing grooves 33 are beneficial to the soft film layer 30 carrying strawberries. When shaking, the strawberries can be cushioned by the overhead convex grooves 32 to avoid direct collisions between the strawberries, thereby further improving the protection effect on the strawberries.

[0086] In one embodiment, the overhead protrusion 32 includes a reinforcement protrusion 323 . The reinforcement protrusion 323 is disposed between the plurality of receiving grooves 33 , and the reinforcement protrusion 323 is disposed around the receiving grooves 33 .

[0087] like Figure 1 As shown, the reinforcing protrusion 323 includes a plurality of side walls, which together form a buffer space, and the side walls close to the receiving groove 33 are arranged around the receiving groove 33 .

[0088] It can be understood that the setting of the buffer space is such that when two adjacent strawberries on the soft film layer 30 move toward each other under the action of an external force, they will first squeeze the side wall adjacent to the receiving groove 33, thereby shrinking the buffer space, playing a buffering role and avoiding collision, thereby avoiding the possibility of direct collision between the two adjacent receiving grooves 33 carrying strawberries and damaging the strawberries.

[0089] On the basis of an array of multiple receiving grooves 33 arranged on the soft film layer 30, the reinforcing convex groove 323 is arranged between two adjacent rows of the receiving grooves 33, and the side walls of the reinforcing convex groove 323 are arranged around the receiving groove 33, so that the two adjacent supporting grooves 33 on the left and right or front and back can be protected by the reinforcing convex groove 323.

[0090] like Figure 1 As shown, the receiving grooves 33 are distributed in an array, and the receiving grooves 33 between two adjacent rows are staggered, so as to maximize the use of the surface of the soft film layer 30 and facilitate the carrying of more strawberries. The reinforcing groove 323 arranged between the two receiving grooves 33 in two adjacent rows can prevent the strawberries on the two adjacent receiving grooves 33 from colliding in multiple directions, thereby improving the protection effect on the strawberries.

[0091] In one embodiment, the overhead protrusion 32 further includes a supporting protrusion 322 and a buckling protrusion 321 . The buckling protrusion 321 is distributed at the edge of the soft film layer 30 , and the supporting protrusion 322 is disposed between the plurality of receiving grooves 33 .

[0092] It should be noted that, in order to prevent the soft film layer 30 from directly contacting the packaging box when the soft film layer 30 is disposed in the packaging box, a plurality of supporting protrusions 322 are disposed on the soft film layer 30 .

[0093] It can be understood that the setting of the supporting groove 322 can make the supporting groove 322 directly abut the packaging box, thereby isolating the soft film layer 30 from the packaging box, thereby preventing the strawberries on the soft film layer 30 from directly colliding with the hard packaging box and damaging the strawberries when the strawberries are displaced, thereby improving the protection effect against the strawberry killer.

[0094] In one embodiment, a support leg is provided in the packaging box, and the soft film layer 30 is separated from the packaging box by plugging and fitting the support frame into the support groove 322 .

[0095] It can be understood that the snap-fitting grooves 321 are distributed on the edge of the soft film layer 30 and are arranged around the multiple receiving grooves 33. Through the arrangement of the multiple snap-fitting grooves 321, the structural strength of the soft film layer 30 is enhanced, and it is also convenient to support the soft film layer 30 inside the packaging box, thereby realizing the separation of the soft film layer 30 from the packaging box.

[0096] In one embodiment, the soft film layer 30 includes:

[0097] a first soft film layer, the first soft film layer;

[0098] a second soft film layer, wherein the first soft film layer is buckled with the second soft film layer;

[0099] Among them, the opening of the receiving groove 33 of the first soft film layer and the opening of the receiving groove 33 of the second soft film layer are arranged one by one opposite to each other, the receiving groove 33 of the first soft film layer and the receiving groove 33 of the second soft film layer are combined to form a storage space, and the overhead convex groove 32 of the first soft film layer is inserted into the overhead convex groove 32 of the second soft film layer.

[0100] In order to achieve all-round wrapping of the strawberries, a first soft film layer and a second soft film layer are set in the packaging box.

[0101] It can be understood that the opening of the receiving groove 33 of the first soft film layer and the opening of the receiving groove 33 of the second soft film layer are arranged one by one opposite to each other. When the first soft film layer is buckled on the second soft film layer, the receiving groove 33 of the first soft film layer and the receiving groove 33 of the second soft film layer are combined to form a storage space, which can be used to prevent strawberries, and the first soft film layer and the second soft film layer realize all-round wrapping of the strawberries, which is convenient for all-round anti-collision protection of the strawberries and improves the protection effect of the strawberries.

[0102] like Figures 2 to 4 As shown, in order to ensure that the first soft film layer can be attached to the second soft film layer and avoid the gap between the first soft film layer and the second soft film layer affecting the protection of strawberries, the opening of the overhead groove 32 on the first soft film layer is in the same direction as the opening of the overhead groove 32 on the second soft film layer.

[0103] It can be understood that when the first soft film layer is buckled onto the second soft film layer, the overhead protrusion 32 on the first soft film layer is inserted into the overhead protrusion 32 of the second soft film layer, thereby achieving closure of the storage space, achieving all-round coverage of the strawberries, and avoiding the formation of gaps between the first soft film layer and the second soft film layer.

[0104] The present invention further provides a packaging box comprising a packaging portion and a soft film layer structure. The specific structure of the soft film layer structure is similar to that of the above-described embodiments. Since the present packaging box utilizes all of the technical solutions of all of the above-described embodiments, it at least possesses all of the beneficial effects of the technical solutions of the above-described embodiments, which will not be described in detail here. A placement space is defined within the packaging portion, and the soft film layer structure is disposed within the placement space.

[0105] like Figure 5 As shown, the soft film layer structure is arranged in the placement space. By adding a soft protective layer inside the hard packaging part, the fragile strawberry support device is prevented from colliding in the packaging part, which may affect the quality of the strawberries.

[0106] In one embodiment, the packaging portion comprises:

[0107] A cover body 10, wherein the cover body 10 is provided with a second ventilating portion 14;

[0108] The box body 20 is buckled onto the cover body 10, and the box body 20 and the cover body 10 together form a storage space;

[0109] In which, the box body 20 is provided with a plurality of accommodating portions 21 protruding away from the placement space, the projection of the accommodating portion 21 on the cover body 10 is located on one side of the second air permeable portion 14, and the accommodating portion 21 is provided with a third air permeable portion 212 passing through the accommodating portion 21, and one of the receiving grooves 33 is embedded in one of the accommodating portions 21, and the receiving groove 33 and the accommodating portion 21 are enclosed to form an isolation space.

[0110] In order to improve the air permeability of the packaging part, a second air permeable portion 14 is provided on the cover body 10, so that the inside and outside of the packaging part are connected through the second air permeable portion 14, thereby facilitating gas exchange between the inside and outside of the packaging part through the second air permeable portion 14, thereby extending the shelf life of the strawberries.

[0111] It is understandable that, in order to increase the gas exchange rate of the packaging portion per unit time, a plurality of second air permeable portions 14 are provided on the cover body 10 , and the plurality of second air permeable portions 14 are distributed at intervals.

[0112] It is understandable that the box body 20 is buckled onto the cover body 10 to achieve relative fixation between the box body 20 and the box body 10, thereby ensuring that the box body 20 and the cover body 10 are separated during the process of the packaging unit carrying strawberries, thereby preventing the box body 20 from being separated from the cover body 10 and affecting the carrying quality.

[0113] It should be noted that the box body 20 and the cover body 10 can be designed as a separate body or a connected body.

[0114] like Figure 5 As shown, the box body 20 and the cover body 10 are of split design. When the box body 20 and the cover body 10 are separated, they are two parts. When the box body 20 and the cover body 10 are buckled together, the edge of the box body 20 is buckled with the edge of the cover body 10, thereby ensuring the relative closure of the placement space and preventing the soft film layer 30 and the strawberries from detaching from the packaging part.

[0115] In one embodiment, the box body 20 and the cover body 10 are of one-piece design, that is, one side edge of the cover body 10 is connected to one side edge of the box body 20, and the box body 20 and the cover body 10 are stacked by rotating the cover body 10, thereby facilitating the buckling of the box body 20 and the cover body 10.

[0116] like Figure 7 and Figure 8 As shown, the accommodating portion 21 is formed on the box body 20 to protrude toward a side away from the cover body 10 , thereby forming an accommodating groove for accommodating the receiving groove 33 .

[0117] It can be understood that when the soft film layer 30 is placed in the placement space, one receiving groove 33 is embedded in one accommodating groove to achieve separation between multiple receiving grooves 33, and the receiving groove 33 is wrapped and protected by the accommodating portion 21.

[0118] It should be noted that a third air permeable portion 212 is provided on the accommodating portion 21, which cooperates with the isolation space between the accommodating portion 21 and the receiving groove 33, so that air can enter and exit the isolation space through the third air permeable portion 212, and enter and exit the receiving groove 33 through the first air permeable portion 34, thereby improving the flow performance of the air in the receiving groove 33 and the air permeability of the packaging portion, which is conducive to extending the shelf life of the loaded strawberries.

[0119] In order to ensure the stability of the packaging portion, the surfaces of the plurality of accommodating portions 21 facing away from the cover body 10 are all located on the same side.

[0120] It is understandable that when transporting the packaging parts containing strawberries, most of the packaging parts are transported by stacking to ensure the transportation quantity, and the surfaces of the multiple receiving parts 21 facing away from the cover body 10 are all on the same side, so that the packaging parts can be stably placed on the transportation equipment or the cover body 10 of other packaging parts.

[0121] It should be noted that, in order to ensure the stability of other packaging parts placed on the packaging part, the surface of the cover body 10 is parallel to the horizontal plane.

[0122] In one embodiment, the box body 20 is provided with a plurality of support protrusions 27 at intervals along the edge, and the plurality of support protrusions 27 are all close to the accommodating portion 21 , and the support protrusions 27 correspond to the buckling protrusions 321 one by one.

[0123] It can be understood that when the soft film layer 30 is placed in the placement space, the soft film layer 30 is supported by the box body 20. In order to ensure the support quality of the soft film layer 30 and prevent the edge of the soft film layer 30 from bending under the action of its own weight, one of the supporting protrusions 27 is inserted into one of the snap-fitting grooves 321. In this way, the soft film layer 30 is supported and the soft film layer 30 is restricted to prevent relative movement of the soft film layer 30 in the placement space.

[0124] In one embodiment, a communication portion 26 is provided between two adjacent accommodating portions 21 . The communication portion 26 is protruded away from the cover body 10 and communicates with the accommodating portions 21 .

[0125] like Figure 8 As shown, in order to ensure air permeability between the accommodating portions 21 after the soft film layer 30 is placed in the placement space, a connecting portion 26 is provided between two adjacent accommodating portions 21 , and the concave direction of the connecting portion 26 is the same as the concave direction of the accommodating portion 21 .

[0126] It can be understood that when the soft film layer is arranged in the placement space, the supporting groove 33 is arranged in the accommodating portion 21, and the soft film layer 30 between the supporting grooves 33 is easily attached to the box body 20, thereby cutting off the gas flow between the two adjacent accommodating portions 21. After the connecting portion 26 is provided, the gas can flow between the two adjacent accommodating portions 21, thereby ensuring the air permeability of the packaging portion after the soft film layer 30 is installed.

[0127] It can be understood that the setting of the connecting portion 26 between two adjacent accommodating portions 21 enables the two adjacent isolation spaces to be connected to each other through the connecting portion 26, thereby facilitating air circulation and exchange between the two adjacent isolation spaces, thereby improving the fluidity of the gas in the supporting groove 33.

[0128] In one embodiment, the surface of the accommodating portion 21 facing away from the cover body 10 is concave to form a ventilation groove 213 , the ventilation groove 213 is open at the side of the accommodating portion 21 , and the side wall of the ventilation groove 213 is provided with the third ventilation portion 212 passing through the accommodating portion 21 .

[0129] In some embodiments, the third air permeable portion 212 is arranged on the side of the accommodating portion 21, so that when multiple packaging portions are stacked, air can enter the isolation space through the side of the accommodating portion 21 to ensure the air permeability of the supporting slot 33.

[0130] It should be noted that when the third air permeable portion 212 is arranged on the side of the accommodating portion 21, it is easy for the third air permeable portion 212 to be blocked by the supporting groove 33, thereby affecting the gas exchange between the isolation space and the outside, and affecting the air permeability of the packaging portion.

[0131] like Figure 7 As shown, the third air permeable portion 212 is provided on the surface of the accommodating portion 21 facing away from the cover body 10 .

[0132] It can be understood that when the supporting groove 33 is embedded in the accommodating portion 21, there is a gap between the side of the supporting groove 33 away from the cover body 10 and the side of the accommodating portion 21 away from the cover body 10, so that the third air permeable portion 212 is arranged on the side of the accommodating portion 21 away from the cover body 10, thereby avoiding the possibility of the third air permeable portion 212 being blocked by the supporting groove 33.

[0133] In order to prevent the cover body 10 of other packaging parts from blocking the third breathable portion 212 when multiple packaging parts are stacked, the surface of the accommodating portion 21 facing away from the cover body 10 is concave to form a breathable groove 213, and the breathable groove 213 is open on the side of the accommodating portion 21, and the side wall of the breathable groove 213 is provided with the third breathable portion 212 that passes through the accommodating portion 21.

[0134] It is understandable that if Figure 6 As shown, when the two packaging parts are stacked, the accommodating portion 21 of the packaging part is arranged on the cover body 10 of the other packaging part. At this time, the surface of the accommodating portion 21 of the packaging part facing away from the cover body 10 is in contact with the cover body 10 of the other packaging part. At this time, the setting of the air permeable groove 213 makes it possible for a gap to exist between the side wall of the air permeable groove 213 where the third air permeable portion 212 is set and the cover body 10, so as to facilitate the circulation of air, thereby ensuring that in the process of stacking multiple packaging parts, air can flow in the isolation space and the supporting groove 33 through the third air permeable portion 212 in the air permeable groove 213 on the bottom surface of the accommodating portion 21, which greatly ensures the air permeability of the packaging part when multiple packaging parts are stacked on each other.

[0135] like Figure 8 As shown, the third ventilation portion is in a hole shape, and in order to ensure ventilation performance, the third ventilation portion includes a plurality of holes.

[0136] Furthermore, in order to reduce the difficulty of processing the third ventilating portion, Figure 16 As shown, the third breathable portion is in a long strip structure and ensures breathability.

[0137] In one embodiment, a positioning portion 12 is provided along the edge of the cover 10 , and the positioning portions 12 provided along the edge of the cover 10 enclose a positioning space, and projections of the plurality of accommodating portions 21 on the cover 10 are all located in the positioning space.

[0138] It is understandable that a plurality of the bearing grooves 33 are formed in an array on the surface of the soft film layer 30 , so that a plurality of the accommodating portions 21 are formed in an array on the box body 10 in order to achieve one-to-one accommodation of the bearing grooves 33 .

[0139] In order to prevent the packaging parts from moving relative to each other and affecting the stacking effect during the stacking process of the packaging parts, a positioning part 12 is provided on the cover body 10, and all the accommodating parts 21 on one packaging part are located in the positioning space of another packaging part, and the positioning part 12 is surrounded on the surface of the cover body 10 to form a supporting surface 11.

[0140] It can be understood that the setting of the positioning portion 12 realizes the positioning and limitation of the placement position of the accommodating portion 21 during the stacking process of the packaging portion, avoids the unstable stacking of the packaging portion, ensures the quality of stacking, and is beneficial to reducing the product packaging volume and reducing the product transportation cost during transportation.

[0141] It can be understood that the positioning portion 12 is arranged along the edge of the cover body 10, so as to facilitate the projection of multiple accommodating portions 21 on the cover body 10, thereby facilitating the direct stacking of multiple packaging portions and improving packaging efficiency.

[0142] In one embodiment, a plurality of positioning portions 12 are provided on an edge of the cover 10 , and a through portion is provided between two adjacent positioning portions 12 .

[0143] It should be noted that the positioning portion 12 encloses to form the positioning space, thereby realizing the stacking positioning of the accommodating portion 21. However, due to the limitation of the positioning portion 12, the flow of air on the surface of the cover body 10 is affected, and since the air permeability groove 213 opens toward the cover body 10 of the other packaging portion when stacking, the air permeability performance of the packaging portion after stacking is further affected.

[0144] like Figure 9 As shown, a plurality of the positioning portions 12 are arranged at intervals along the edge of the cover body 10 , and the through portion is provided between two adjacent positioning portions 12 .

[0145] It can be understood that the setting of the through-portion realizes the intermittent design of the positioning portion 12, so that when the gas flows on the surface of the cover body 10, the gas exchange between the inside and outside of the positioning space can be carried out through the through-portion, thereby ensuring the air permeability of the third air permeable portion 212 in the air permeable groove 213 after stacking.

[0146] In one embodiment, the packaging portion is a rectangular structure, and the multiple accommodating portions 21 are in a rectangular array. In order to achieve the positioning of the packaging portion after stacking, there are at least four positioning portions 12, and the four positioning portions are bent and distributed at the four corners of the surface of the cover body 10, so as to achieve the positioning restriction of the packaging portion after stacking.

[0147] Further, when the positioning portions 12 are greater than four, the positioning portions 12 can be distributed at intervals between adjacent two bending positioning portions, so as to facilitate positioning and limiting of other containing portions 21 of the stacked packaging portions.

[0148] It should be noted that among the plurality of positioning portions 12 distributed at intervals along the edge of the cover body, the diagonally arranged positioning portions 12 are in a bending shape, and other positioning portions 12 can have any shape that does not interfere with the diagonal positioning effect.

[0149] In an embodiment, a fourth air permeable portion 13 is arranged on the cover body 10 between adjacent two positioning portions 12.

[0150] In order to ensure the air permeability of the supported packaging portion when a plurality of packaging portions are stacked and stored, the fourth air permeable portion 13 is arranged on the surface of the cover body 10 opposite to the through portion.

[0151] Since the containing portion 21 of the stacked packaging portion is located in the positioning space when stacked, the fourth air permeable portion 13 opposite to the through portion can not be affected by the stacked packaging portion, so as to ensure the air permeability of the supported packaging portion when stacked.

[0152] As shown in FIG. 1, Figure 6 It can be understood that the second air permeable portion 14 is arranged on the supporting surface 11, so that when a plurality of packaging portions are stacked and arranged, the stacked packaging portions are placed on the supporting surface 11.

[0153] It should be noted that in order to avoid the stacked packaging portion from blocking the second air permeable portion 14 on the supporting surface 11, the projection of the containing portion 21 on the cover body 10 avoids the second air permeable portion 14.

[0154] It can be understood that through the arrangement of the through portion, air can flow on the surface of the supporting surface 11. The fourth air permeable portion 13 opposite to the through portion and the unblocked second air permeable portion 14 can ensure the air permeability of the supported packaging portion, thereby ensuring the packaging volume of the product during stacking and transportation, reducing the product transportation volume, and ensuring the air permeability of the packaging portion and prolonging the preservation time of the strawberries.

[0155] It should be noted that as shown in FIG. 1, Figure 15 A plurality of fourth air permeable portions 13 are arranged in the positioning space, and the fourth air permeable portions 13 are arranged close to the positioning portions 12. The plurality of fourth air permeable portions 13 are arranged along the edge of the cover body 10.

[0156] It is understandable that the fourth air permeable portion 13 is provided on the surface of the cover body 10 in the positioning space, so as to ensure the structural strength of the cover body 10 while ensuring the air permeability of the placement space through the fourth air permeable portion 13 .

[0157] In one embodiment, the cover 10 is provided with a plurality of first legs 15 on a surface facing the box body 20 , and the plurality of first legs 15 are inserted into the overhead protrusions 32 to fix the soft film layer 30 relative to the cover 10 ;

[0158] And / or, a plurality of second legs 25 are provided on the surface of the box body 20 facing the cover body 10 , and the plurality of second legs 25 are plugged into the overhead protrusions 32 to fix the soft film layer relative to the box body 20 .

[0159] like Figures 10 to 12 As shown, a plurality of first legs 15 are provided on the cover body 10, so that when the plurality of first legs 15 are respectively inserted into different supporting grooves 322, the soft film layer 30 can be supported in the placement space, so that there is a gap between the soft film layer 30 and the cover body 10 and the box body 20, thereby preventing the soft film layer 30 from colliding with the cover body 10 and / or the box body 20 and causing damage to the strawberries.

[0160] In order to prevent the first supporting leg 15 from affecting the second ventilating portion 14 , the projection of the first supporting leg 15 on the cover 10 avoids the second ventilating portion 14 .

[0161] It is understandable that when the first leg 15 abuts against the overhead protrusion 32, there is a gap between the soft film layer 30 and the cover body 10, so as to facilitate the ventilation of the placement space by the second ventilating portion 14 and ensure the ventilation effect.

[0162] like Figure 8 As shown, a plurality of second legs 25 are provided on the box body 20. When the plurality of second legs 25 are respectively inserted into different supporting grooves 322, the soft film layer 30 can be supported in the placement space, so that there is a gap between the soft film layer 30 and the cover body 10 and the box body 20, thereby preventing the soft film layer 30 from colliding with the cover body 10 and / or the box body 20 and causing damage to the strawberries.

[0163] It is understandable that the second leg 25 is provided on the connecting portion 26 to avoid interference with the receiving portion 21 and thus affecting the placement of the strawberries.

[0164] It can be understood that when multiple first legs 15 are provided on the cover body 10 and multiple second legs 25 are provided on the box body 20, the first legs 15 and the second legs 25 jointly support the soft film layer 30, thereby improving the stability of the soft film layer 30 in the placement space, avoiding the collapse of the soft film layer 30 affecting the loading of strawberries, and avoiding the collision of the soft film layer 30 with the cover body 10 and / or the box body 20, thereby improving the protection quality of the strawberries during loading and transportation.

[0165] In one embodiment, the edge of the cover 10 extends toward the box body 20 and is bent to form a first buckling portion 17 , and the edge of the box body 20 is bent to form a second buckling portion 23 ;

[0166] The first buckling portion 17 is buckled with the second buckling portion 23 , and a breathable gap is formed between the first buckling portion 17 and the second buckling portion 23 .

[0167] like Figure 13 and Figure 14 As shown, a breathable gap is formed between the first snap-fit ​​portion 17 and the second snap-fit ​​portion 23, so that the placement space is directly connected to the outside through the breathable gap, thereby ensuring the breathability of the packaging portion, allowing air to directly enter and exit the placement space through the breathable gap, which is beneficial to improving the breathability of the supporting groove 33 through the first breathable portion 34.

[0168] like Figure 13 and Figure 14 As shown, a plurality of first abutment members 18 are provided on the side of the first buckling portion 17 facing the second buckling portion 23, and a plurality of second abutment members 24 are provided on the side of the second buckling portion 23 facing the first buckling portion 17, and the first abutment members 18 and the second abutment members 24 are provided in a one-to-one correspondence.

[0169] It can be understood that when the cover body 10 is buckled with the box body 20, the first abutment member and the second abutment member abut against each other, and the first abutment member 18 protruding from the first buckling portion 17 and the second abutment member 24 protruding from the second buckling portion 23 form the air-permeable gap between the first buckling portion 17 and the second buckling portion 23, thereby facilitating the direct entry and exit of air into and out of the placement space, thereby improving the air permeability of the packaging portion.

[0170] In order to prevent the cover 10 from automatically separating from the box body 20 after being fastened together, the first abutment 18 is inserted into the second abutment 24, and / or the second abutment 24 is inserted into the first abutment 18, so as to prevent the cover 10 from being easily separated from the box body 20 and affecting the support and fixation of the strawberries, thereby ensuring the stability of the strawberries during transportation.

[0171] Furthermore, in order to improve the fixing quality of the cover body 10 and the box body 20 after being fastened together, a plurality of first locking members 16 are provided on the side of the first fastening portion 17 facing the second fastening portion 23, and a plurality of second locking members 22 are provided on the side of the second fastening portion 23 facing the first fastening portion 17. The second locking members 22 correspond to the first locking members 16 one by one, and the first locking members 16 are connected to the second locking members 22.

[0172] It is understandable that a limiting groove for accommodating the first locking member 16 is provided on the second locking member 22 , or a limiting groove for accommodating the second locking member 22 is provided on the first locking member 16 .

[0173] It can be understood that when the cover 10 is buckled with the box body 20, the first locking member 16 or the second locking member 22 is inserted into the limiting groove, thereby achieving an interference fit between the first locking member 16 and the second locking member 22, thereby preventing the cover 10 from being easily separated from the box body 20, and further preventing the cover 10 from being separated from the box body 20 when the packaging part is subjected to unstable external forces such as vibration, thereby affecting the storage of strawberries.

[0174] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
