Description

Technical Field

[0001] This application relates to the field of logistics packaging technology, specifically to a packaging structure. Background Technology

[0002] Cluster fruits (such as bunch tomatoes, grapes, and wampee) are mostly in bunch shape, with loosely packed bunches and varying weights per bunch. Currently, these fruits are often packaged in courier services using a combination of absorbent paper, air-filled bags, and ice packs. However, this packaging method is cumbersome and labor-intensive, has poor air permeability, is prone to leakage and damage, and has insufficient cushioning. Consumers often find that the fruits are detached, damaged, have browned stems, or even mold and rot upon receiving them. This not only reduces the online shopping experience for consumers but also limits the development of e-commerce sales models for cluster fruits. Utility Model Content

The second receiving groove is located between the first receiving groove and the third receiving groove. Furthermore, the second end of the first receiving groove, the first end of the second receiving groove, and the second end of the third receiving groove are located on the same side of the receiving tray.

[0014] Optionally, in the above packaging structure, the first receiving groove and the third receiving groove are symmetrically arranged about the center line of the second receiving groove;

[0015] And / or,

[0017] Optionally, in the above packaging structure, the receiving tray includes a partition, and the first receiving groove and the second receiving groove, as well as the second receiving groove and the third receiving groove, are all separated by the partition, and the height of the partition is less than the depth of the receiving groove.

[0018] Optionally, in the above packaging structure, the first receiving groove is provided with a first reinforcing part, the second receiving groove is provided with a second reinforcing part, the third receiving groove is provided with a third reinforcing part, and the surface of the receiving tray with the opening of the groove is provided with a fourth reinforcing part, wherein...

[0021] The first reinforcing part, the second reinforcing part, and the third reinforcing part are all deepened grooves;

[0022] The fourth reinforcing part includes a reinforcing protrusion and a reinforcing groove, and the reinforcing protrusion and the reinforcing groove are symmetrically arranged about the center line of the second receiving groove.

[0023] Optionally, the above packaging structure also includes a snap-fit ​​structure disposed on the surface of the receiving tray with the slot, the snap-fit ​​structure including a snap-fit ​​groove and a snap-fit ​​protrusion;

[0024] The two receiving trays are fitted together to form a packaging box. The two receiving trays are connected by the snap-fit ​​groove and snap-fit ​​protrusion on one tray and the snap-fit ​​protrusion and snap-fit ​​groove on the other tray, respectively.

This allows each string of items to be individually contained within its slot, achieving single-string packaging and preventing mutual compression between multiple strings. Furthermore, a support film is provided on the receiving tray. During the process of placing the string of items into the receiving slots, the support film suspends and supports the items, preventing direct contact between the items and the relatively hard bottom wall of the receiving slots. The receiving tray containing the string of items can then be placed into an outer casing for sealing and transportation. In this structure, by allowing each receiving slot to hold a single string of items, mutual compression between multiple strings of items is avoided. Furthermore, by suspending the strings of items in the receiving slots with a supporting film, direct contact between the strings of items and the rigid receiving trays is prevented. This minimizes damage to the strings of items during transportation, preventing issues such as fruit detachment, browning, mold, and rot, and significantly improves the packaging effect for strings of items.

[0040] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] like Figures 1-4 As shown in the figure, this application provides a packaging structure that can be used to package easily damaged items such as fruits, thereby preventing the fruits from rotting and spoiling during transportation. This packaging structure is particularly suitable for fresh bunches of fruits with high packaging requirements, such as bunches of tomatoes, grapes, wampee, or longan. The following description uses fresh bunches of fruits as an example to illustrate the packaging structure.

[0042] The packaging structure mainly includes a receiving tray 1, a supporting film, and an outer box. The receiving tray 1 is the component for placing, containing, and positioning bunches of fruit. The receiving tray 1 has receiving slots 2, in which the bunches of fruit to be packaged are placed. The shape of each receiving slot 2 matches the shape of a single bunch of fruit. Since bunches of fruit (such as a bunch of grapes) are generally inverted cone shapes, the shape of the receiving slot 2 can be set to a cone-like shape or a semi-cone shape (a semi-cone refers to half a cone obtained by cutting along the center line of a cone). That is, each receiving slot 2 on the receiving tray 1 is only used to hold one bunch of fruit. The bunches of fruit are placed in different receiving slots 2, thus isolating the bunches of fruit from each other. A support film (not shown in the figure) is placed on the receiving tray 1 and covers the opening of the receiving slot 2. As the name suggests, the support film is used to support the bunches of fruit. The support film can be made of different materials or in different ways. For example, the support film can be laid flat on the surface of the receiving tray 1 where the receiving slot 2 is opened, and the support film can be made of an elastic material that can undergo elastic deformation. When the bunches of fruit are put into the receiving slot 2, because the support film covers the opening of the receiving slot 2, the support film will bear the weight of the bunches of fruit. Under the action of the weight of the bunches of fruit The supporting membrane undergoes elastic deformation (specifically, it is stretched), meaning the bunch of fruit presses against a portion of the covering opening of the supporting membrane and moves into the receiving groove 2, allowing the bunch of fruit to enter the receiving groove 2. However, under the elastic force of the supporting membrane, the bunch of fruit does not contact the bottom wall of the receiving groove 2. In other words, under the support of the supporting membrane, the bunch of fruit is suspended in the receiving groove 2, with a gap between it and the bottom wall of the receiving groove 2 (the weight of the bunch of fruit is insufficient to cause the supporting membrane to continue stretching and deforming), thus avoiding hard contact between the bunch of fruit and the wall of the receiving groove 2; alternatively, the supporting membrane may not be made of an elastic material, but rather it may be loosely laid out. On the surface of the receiving tray 1 with the opening of the receiving groove 2 (for example, the carrier film is 3cm-4cm away from the surface of the receiving tray 1 in its natural state), when the string of fruits is placed into the receiving groove 2, the carrier film is pressed into the receiving groove 2 by the weight of the string of fruits until the carrier film is stretched. When the carrier film is stretched, the string of fruits is suspended in the receiving groove 2, and there is a gap between the string of fruits and the bottom wall of the receiving groove 2. After the string of fruits is placed on the receiving tray 1, the receiving tray 1 and the string of fruits can be placed together into the outer box (not shown in the figure), and the outer box is sealed to complete the packaging of the string of fruits.

[0043] The aforementioned packaging structure, on the one hand, achieves independent packaging of single bunches of fruit by setting up receiving slots 2 that match the individual bunches of fruit, avoiding mutual compression between multiple bunches and reducing damage; on the other hand, using a carrier film to suspend the bunches of fruit in the receiving slots 2 avoids hard contact between the bunches of fruit and the side walls and / or bottom walls of the receiving slots 2, reducing or preventing damage caused by bumps and vibrations during transportation. This minimizes damage to the bunches of fruit during transportation, reducing or preventing issues such as fruit detachment, browning, mold, and rot, significantly improving the packaging effect for bunches of fruit.

[0044] The structure and arrangement of the carrier film can be varied. For example, in one optional embodiment, the carrier film is simply a sheet-like film that covers the surface of the receiving tray 1 where the receiving groove 2 is located and is connected to the four edges of the surface. That is, the size of the sheet-like carrier film is the same as or close to the surface of the receiving tray 1 with the opening, and the four edges of the sheet-like carrier film are connected (for example, by heat sealing) to the four edges of the receiving tray 1. In this way, the carrier film only covers the opening surface of the receiving tray 1, thereby reducing the amount of carrier film used and lowering costs.

[0045] Alternatively, in another optional embodiment, the carrier film can be processed into a wrapping bag, and the receiving tray 1 is contained within the sealed wrapping bag. That is, by folding and sealing the sheet-like carrier film, a wrapping bag is formed (the volume of the wrapping bag must be larger than the volume of the receiving tray 1). During the packaging structure assembly process, the receiving tray 1 can be directly inserted into the wrapping bag, and then the wrapping bag is sealed, which makes the assembly of the receiving tray 1 and the carrier film more convenient. Furthermore, during the assembly process, some gas can be filled into the wrapping bag to give the carrier film a better suspension bearing effect on the bunched fruits.

[0046] Since the shape of the receiving groove 2 matches the shape of a single bunch of fruit, the approximately conical receiving groove 2 and its opening have a certain length along the axial direction of the cone. The axial direction of the cone is the length direction of the receiving groove 2. The two ends of the opening along the length direction of the receiving groove 2 are the first end 201 and the second end 202, respectively, and the width of the first end 201 is greater than the width of the second end 202. Based on this, such as Figures 1-4As shown, multiple receiving slots 2 are provided on the same receiving plate 1 so that the receiving plate 1 can simultaneously hold multiple strings of fruit. For example, a first receiving slot 203, a second receiving slot 204 and a third receiving slot 205 are provided adjacent to each other on the same receiving plate 1. The second receiving slot 204 is located between the first receiving slot 203 and the third receiving slot 205. Furthermore, the second end 202 of the first receiving slot 203, the first end 201 of the second receiving slot 204 and the second end 202 of the third receiving slot 205 are located on the same side of the receiving plate 1. Because the first end 201 of the receiving slot 2 is wider and the second end 202 is narrower, and its shape is irregular, if the first end 201 of all the receiving slots 2 is located on one side of the receiving tray 1 and the second end 202 is located on the other side of the receiving tray 1, even if the first ends 201 of adjacent receiving slots 2 are set close to each other (or close to each other), there will still be a gap between the two second ends 202 of adjacent receiving slots 2. This will lead to wasted space in the receiving tray 1 and limit the number of receiving slots 2 set on the receiving tray 1. However, if the two ends of adjacent receiving slots 2 are reversed, that is, the first end 201 of the second receiving slot 204 located in the middle and the second ends 202 of the first receiving slot 203 and the third receiving slot 205 on both sides are located on the same side of the receiving tray 1, the space of the receiving tray 1 can be fully utilized and the space can be avoided. More receiving slots 2 can be set without increasing the volume of the receiving tray 1, so that the packaging structure provided by this application can realize the one-time packaging of more bunches of fruit.

[0047] Furthermore, in order to better optimize the structure of the receiving disk 1, such as... Figure 3 As shown, the first receiving groove 203 and the third receiving groove 205 are also aligned with the center line of the second receiving groove 204 (i.e., Figure 3 The dotted lines in the image are symmetrically arranged. This arrangement ensures that the bunches of fruit being packaged are evenly spaced, resulting in a more reasonable distribution and minimizing the negative effects of squeezing between them. Furthermore, it improves the stress balance of the receiving tray 1, allowing it to more stably support and position the bunches of fruit, thus further enhancing the packaging effect.

[0048] Although the receiving groove 2 is designed and manufactured to match the shape of the bunch of fruit, the size of the bunches of fruit is not uniform, and the bunches are sometimes loose and misshapen when placed on the supporting film. Therefore, there are situations where the receiving groove 2 cannot adequately accommodate the bunches of fruit, resulting in some fruit pieces remaining outside the receiving groove 2. Based on this, if... Figures 1-4As shown, in an optional embodiment, expansion grooves 3 are provided at the second end 202 of the first receiving groove 203 and the second end 202 of the third receiving groove 205, and the two expansion grooves 3 are symmetrically arranged about the center line of the second receiving groove 204. This increases the volume and length of the receiving groove 2, allowing excess portions of larger or loosely packed bunches of fruit to enter the expansion grooves 3, thus improving the capacity for holding bunches of fruit. Specifically, to improve the expansion effect, the depth of the expansion groove 3 is not less than the depth of the receiving groove 2, and to increase the volume of the expansion groove 3, it is also made into an elliptical groove, with its long axis extending to the corners of the rectangular receiving plate 1.

[0049] like Figure 1 and Figure 3 As shown, the receiving tray 1 includes a dividing section 101. The first receiving groove 203 and the second receiving groove 204, the third receiving groove 205, are all separated by the dividing section 101, and the height of the dividing section 101 is less than the depth of the receiving groove 2. That is, the dividing section 101 divides the large groove on the receiving tray 1 into the first receiving groove 203, the second receiving groove 204, and the third receiving groove 205, and also makes the height of the dividing section 101 less than the depth of the receiving groove 2, meaning the top edge of the dividing section 101 is lower than the opening of the receiving groove 2. This is because when the bunch of fruit to be packaged is large or loose and cannot be accommodated by a single receiving groove 2, the excess portion of the bunch of fruit can overflow into adjacent receiving grooves 2 through the lower dividing section 101, which can significantly improve the efficiency of the middle receiving groove. The second receiving slot 204 has a better containing effect because the second receiving slot 204, which is located in the middle, does not have an expansion slot 3 (there is not enough space near the second receiving slot 204 to set up an expansion slot 3). Moreover, the second receiving slot 204 has partitions 101 on both sides. This allows the bunches of fruit placed in the second receiving slot 204 to overflow into the first receiving slot 203 and the third receiving slot 205 at the same time through the partitions 101 on both sides. This better meets the packaging requirements of bunches of fruit of different sizes and greatly reduces the packaging restrictions on bunches of fruit caused by the fixed shape and size of the receiving slot 2.

[0050] In optional embodiments, such as Figures 1-4 As shown, a first reinforcing part 102 is provided in the first receiving groove 203, a second reinforcing part 103 is provided in the second receiving groove 204, a third reinforcing part 104 is provided in the third receiving groove 205, and a fourth reinforcing part is provided on the surface of the receiving tray 1 with the slot. By providing reinforcing parts in each receiving groove 2 and on the surface of the receiving tray 1, not only can the structural strength of each receiving groove 2 be increased, but also the structural strength of the entire receiving tray 1 can be increased, so that the bunch of fruits can be more stably supported and restrained, reducing the impact of bumps and vibrations on the bunch of fruits during transportation.

[0051] Specifically, such as Figure 3 As shown, when setting each reinforcing part, the first reinforcing part 102 and the third reinforcing part 104 are symmetrically arranged about the center line of the second receiving groove 204. This can optimize the structural strength of the first receiving groove 203 and the third receiving groove 205, and further improve the structural strength of the entire receiving plate 1, making its overall structural strength more uniform. The center line of the second reinforcing part 103 coincides with the center line of the second receiving groove 204, that is, the second reinforcing part 103 itself is a symmetrical structure, which can better improve the force balance of the receiving plate 1 and improve the support effect on the string of fruits.

[0052] The specific structure of the reinforcing part can be chosen in different ways, such as a thickened structure or a concave-convex structure. In this application, the first reinforcing part 102, the second reinforcing part 103 and the third reinforcing part 104 are all deep grooves set at the bottom of the receiving groove 2. This not only improves the structural strength, but also further increases the volume of the receiving groove 2, so that the structural strength of the receiving tray 1 is improved while its packaging effect is also improved.

[0053] like Figures 1-4 As shown, the fourth reinforcing part includes a reinforcing protrusion 105 and a reinforcing groove 106. The positions of the reinforcing protrusion 105 and the reinforcing groove 106 are symmetrical about the center line of the second receiving groove 204, so that they can better cooperate with the second reinforcing part 103 to improve the structural strength near the center line of the receiving plate 1.

[0054] In the aforementioned reinforcing structure, it is preferable that the first reinforcing part 102, the third reinforcing part 104, and the fourth reinforcing part are disposed as close as possible to the different edges of the receiving tray 1, thereby maximizing the overall structural strength of the receiving tray 1. Meanwhile, the second reinforcing part 103 has a larger area than the first reinforcing part 102, the third reinforcing part 104, and the fourth reinforcing part, and it is disposed in the middle of the second receiving groove 204. To prevent its outline from damaging the string of fruits, the depth of the groove-shaped second reinforcing part 103 is kept within 5 mm.

[0055] In the above packaging structure, when packaging bunches of fruit, only one receiving tray 1 can be used to support the bunches of fruit, and then the receiving tray 1 and the bunches of fruit it supports can be placed into the outer box for sealing. However, in this structure, the receiving tray 1 is in an open state, and the bunches of fruit placed in the receiving slot 2 may still be damaged by bumping into the outer box. Therefore, in order to further improve the packaging effect, the packaging structure in this application can use two receiving trays 1 to cover each other (that is, the two surfaces of the two receiving trays 1 with slots are attached to each other) to form a packaging box to seal the bunches of fruit. In this structure, two first receiving slots 203 located on two receiving trays 1 cooperate to package the same bunch of fruit. That is, the two first receiving slots 203 form a receiving cavity for a single bunch of fruit, and the three-dimensional space of the receiving cavity matches the shape of the single bunch of fruit. Similarly, two second receiving slots 204 located on two receiving trays 1 cooperate to package the same bunch of fruit, and two third receiving slots 205 located on two receiving trays 1 cooperate to package the same bunch of fruit.

[0056] like Figures 1-4 As shown, when using two trays 1 to seal and package a string of fruits, the packaging structure also includes a snap-fit ​​structure 4 on the slotted surface of each tray 1. The snap-fit ​​structure 4 includes a snap-fit ​​groove 401 and a snap-fit ​​protrusion 402. When the two trays 1 are closed, they are connected by snapping the snap-fit ​​groove 401 and protrusion 402 on one tray with the snap-fit ​​protrusion 402 and groove 401 on the other tray. Using this snap-fit ​​structure 4 to connect the two trays 1 replaces the method of wrapping the two trays 1 with tape. This method is not only simple in structure but also makes the packaging operation simpler and more convenient, improving packaging efficiency.

[0057] In an optional embodiment, the sidewall of the receiving trough 2 may be provided with multiple positioning grooves (not shown in the figure) that match the individual fruit pieces in the bunch. By providing these positioning grooves, the receiving trough 2 can not only independently package the entire bunch of fruit, but also more stably position the fruit pieces in the bunch, thus better reducing the movement of the fruit pieces during transportation, reducing mutual compression between different fruit pieces in the same bunch, and further reducing damage to the fruit pieces during transportation.

[0058] Furthermore, the side walls and bottom walls of the receiving groove 2 are both curved, and the side walls and bottom walls are smoothly connected, making the receiving groove 2 an arc-shaped groove. Setting the receiving groove 2 as an arc-shaped groove not only makes it easier to process, but also the smooth inner wall without sharp edges can reduce the impact on the bunches of fruits during transportation, further reducing the damage to the fruit during transportation.

[0059] Alternatively, the side walls and bottom walls of the receiving groove 2 can be made flat, with a right angle or an obtuse angle between them, making the receiving groove 2 a polygonal groove. That is to say, in addition to an arc-shaped groove, the receiving groove 2 can also be set as a polygonal groove, such as a rectangular groove, which can further increase the volume and fully accommodate the bunches of fruit.

[0060] In this application, the preferred material for the receiving tray 1 is a one-piece molded paper-plastic tray, which not only meets packaging requirements well but is also easy to process, inexpensive, and suitable for use as a packaging structure for consumables. Specifically, the preferred pulp ratio for the paper-plastic tray is: 15% sugarcane pulp + 25% bamboo pulp + 60% wood pulp.

[0061] The carrier film is made of PE, PLA, PVC, or TPU material, featuring low adhesion and a thickness of approximately 8 mils. It is connected to the paper-plastic model using a heat-sealing process. To meet the breathability and water permeability requirements for fruit transportation, the carrier film incorporates multiple micropores—achieved through laser perforation of the film material. The average pore diameter is approximately 57 μm, arranged in a Z-shape, with a pore density of 40 pores per unit area. The laser speed V = 200 mm / s, pulse repetition frequency PRF = 15 kHz, and current I = 7 A. This design gives the carrier film good breathability and moisture absorption, effectively reducing field heat and preventing excessive moisture accumulation that leads to condensation and accelerated spoilage, thus helping to maintain fruit quality.

[0062] In addition, the outer box is made of common paper material, and its structure can be found in common outer packaging cartons.

[0063] In summary, the packaging structure provided in this application has the following advantages:

[0064] 1. The entire packaging structure consists only of the outer box, the receiving tray 1, and the carrier film;

[0065] 2. By using the carrier film and the structure of the carrier film combined with the receiving tray 1, the packing operation can be made more convenient. The string of fruits can be placed directly on the carrier film and then the upper and lower receiving trays 1 can be fastened. The overall packing time is reduced by about 50% compared with traditional foam box packaging.

[0066] 3. The packaging structure of this application eliminates the need for ice packs compared to traditional foam packaging;

[0067] 4. For the same size, the packaging structure of this application increases the capacity of string-of-fruits by about 20% compared with traditional foam box packaging;

[0068] 5. Under the same fruit and the same transportation time, the packaging structure of this application reduces the damage rate by approximately 50% compared to traditional packaging;

[0069] 6. The packaging structure of this application can be used for different fruits, different sizes and different weights in bunches, with great size compatibility; the packaging operation is simple and labor-saving, no auxiliary equipment is required, the packaging efficiency is high and the labor cost is low.

[0070] 7. The structure of the container tray is symmetrical and has a small physical volume. It can be stacked before use, which facilitates manufacturing and transportation and reduces storage and transportation costs.
