[0042] See also Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application proposes a packaging structure for fragile goods, Figure 1 This is a schematic diagram of the overall structure of a packaging structure for fragile items in one embodiment of the present application. Figure 2 for Figure 1 Side view of the packaging structure. Figure 3 for Figure 1 The packaging structure of this embodiment includes: a first base 10 and a first film 30.

[0043] The first base 10 includes a first base body 15 and a first opening surface 13, and a first film 30 is fixedly disposed on the first opening surface 13; a cavity is formed between the first film 30 and the first base body 15.

[0044] The first film 30 is ductile. When the first film 30 is subjected to pressure from the target vulnerable product, it is extended toward the bottom of the first base body 15 . After the first film 30 is extended, there is a gap between the first film 30 and the bottom and side of the first base body 15 .

[0045] Among them, the target fragile goods include but are not limited to fresh food, ceramics, glass, electronic products and other items that are easily damaged during transportation.

[0046] Specifically, the first base 10 is mainly used to bear the weight of the entire packaging structure. The first base 10 includes a first base body 15. The first base body 15 is mainly used to support the packaging structure. If the target fragile goods are placed in the packaging structure, the first base body 15 is used to withstand the bumps and pressure during transportation. The first base 10 also includes a first opening surface 13, which is directly connected to the first base body 15. The first opening surface 13 is a plane corresponding to the packaging structure in the opening direction. There is an opening in the first opening surface 13, and the target fragile goods are placed in the packaging structure through the opening. The first film 30 is used to cover the first opening surface 13 corresponding to the first base 10, so that the horizontal surface around the opening of the first opening surface 13 is completely covered by the first film 30. The opening of the first opening surface 13 can be used to place the target fragile goods through the first film 30. At this time, a cavity is formed between the first film 30 and the first base body 15, such as a first cavity 51.

[0047] At this time, the first base 10 and the first film 30 together constitute a packaging structure, and the target fragile goods are placed at the opening corresponding to the first film 30. When the first film 30 is subjected to the pressure from the target fragile goods, the first film 30 will extend in the direction of pressure according to its own ductility, that is, extend toward the bottom direction of the first base body 15, and the extension depth is positively correlated with the pressure of the target fragile goods. For example, the target fragile goods may be grapes, which are placed on the first film 30. The first film 30 will be deformed toward the bottom direction of the first base body 15, and there will be gaps between the deformed first film 30 and the bottom and side surfaces of the first base body 15, so that the target fragile goods will not directly contact the first base 10, and the weight of the target fragile goods will only be directly borne by the first film 30.

[0048] The packaging structure of fragile goods provided in the embodiment of the present application comprises a first base 10 and a first film 30, wherein the first base 10 comprises a first base body 15 and a first opening surface 13, the first film 30 is fixedly arranged on the first opening surface 13, a cavity is formed between the first film 30 and the first base body 15; and the first film 30 has ductility, the first film 30 extends toward the bottom direction of the first base body 15 under the pressure from the target fragile goods, and there is a gap between the first film 30 and the bottom and side of the first base body 15 after the extension. The target fragile goods can be placed on the first film 30, and when the target fragile goods shake during transportation, the ductility of the first film 30 provides a certain buffer space for the fragile goods, and there is a gap between the first film 30 and the bottom and side of the first base body 15 after the extension, so the target fragile goods and the first base body 15 will not be squeezed or collided due to contact, thereby improving the safety of the fragile goods during transportation.

[0049] Figure 4 Schematic diagram of a partial structure of a packaging structure of fragile goods in an embodiment of the present application. In an exemplary embodiment, the packaging structure further includes a second base 20 and a second film 40.

[0050] The second base 20 includes a second base body 25 and a second opening surface 23, and a second film 40 is disposed on the second opening surface 23; the second film 40 is ductile, and after the second film 40 is extended, there is a gap between the second film 40 and the bottom and side of the second base body 25;

[0051] The first base 10 and the first film 30 form a first structure, and the second base 20 and the second film 40 form a second structure. When the first structure and the second structure are combined, an elastic space 53 for covering the target fragile product is formed between the first film 30 and the second film 40.

[0052] Specifically, the first base 10 and the second base 20 can be combined to form a packaging structure with four sides closed, and the outer part of the packaging structure can bear weight in at least six directions such as up, down, left, right, front and back. Among them, the second base 20 includes a second base body 25, which is mainly used to support the packaging structure. If the target fragile goods are placed in the packaging structure with four sides closed, the first base body 15 and the second base body 25 can both bear the bumps and pressure during transportation. The second base 20 also includes a second opening surface 23, which is directly connected to the second base body 25. The second opening surface 23 is a plane corresponding to the packaging structure in the opening direction. There is an opening in the second opening surface 23, and the target fragile goods are placed in the second film 40 through the opening. The second film 40 is used to cover the second opening surface 13 corresponding to the second base 20, so that the surface around the opening of the second opening surface 23 is completely covered by the second film 40, and the opening of the second opening surface 23 can be used to place the target fragile goods through the second film 40.

[0053] Based on this, the first base 10 and the first film 30 can form a bottom bearing structure, i.e., a first structure, and the second base 20 and the second film 40 can form a top bearing structure, i.e., a second structure. The target fragile goods are wrapped by the first film 30 of the bottom bearing structure and the second film 40 of the top bearing structure, i.e., after the bottom bearing structure and the top bearing structure are combined, the target fragile goods are wrapped by the first film 30 and the second film 40, and the target fragile goods are not in direct contact with the first base 10 and the second base 20, and there is a gap between the target fragile goods and the bottom and side of the first base body 15 and the second base body 25, such as the first cavity 51 and the second cavity 52.

[0054] like Figure 5 The figure shows an overall structural schematic diagram of the packaging structure of fragile goods in an embodiment of the present application. The packaging structure can be composed of a first base 10, a first film 30, a second base 20 and a second film 40, wherein the first base 10 and the second base 20 are mirror-fitted, so that the first opening surface 13 and the second opening surface 23 are fit together, and at this time, the first film 30 and the second film 40 are fit together, so that the first film 30 and the second film 40 wrap the target fragile goods through fitting.

[0055] like Figure 6The figure shows a schematic diagram of the internal structure of the fragile goods in the embodiment of the present application. When the first structure and the second structure are combined, an elastic space 53 can be formed. The elastic space 53 is used to prevent the target fragile goods from colliding with the packaging structure. The elastic space 53 can be formed based on the wrapping of the target fragile goods by the first film 30 and the second film 40, and the first structure itself has a first space 51, and the second structure itself has a second space 52. When the target fragile goods are overturned, bumped, etc. during transportation, the target fragile goods wrapped by the first film 30 and the second film 40 can squeeze the first space 51 and the second space 52, but the target fragile goods will not directly contact the first base body 15 and the second base body 25.

[0056] The embodiment of the present application combines a first structure consisting of a first base 10 and a first film 30, and a second structure consisting of a second base 20 and a second film 40, so that the target fragile goods are placed in the package of the first film 30 and the second film 40. Since the target fragile goods are suspended in the cavity formed by the first structure and the second structure after being wrapped, the packaging structure will not cause collision between the target fragile goods and the first structure and the second structure during transportation after being flipped or transported, thereby further improving the transportation safety of the target fragile goods.

[0057] In an exemplary embodiment, Figure 3 and Figure 4 As shown, the first base 10 and the second base 20 are both provided with a plurality of reinforcing structures, and the first film 30 and the second film 40 do not contact any reinforcing structure after being extended. The reinforcing structure can be divided into a transverse reinforcing structure and a longitudinal reinforcing structure, and the number of the reinforcing structures is not specifically limited. For example, the transverse reinforcing structure can be a reinforcing beam, and the longitudinal reinforcing structure can be a reinforcing rib, and the reinforcing beam and the reinforcing rib are perpendicular to each other. Figure 3 The first reinforcement structure 11 in the figure represents the longitudinal reinforcement structure corresponding to the first base 10, and the second reinforcement structure 12 represents the transverse reinforcement structure corresponding to the first base 10. Figure 4 The third reinforcement structure 21 in the figure represents the longitudinal reinforcement structure corresponding to the second base 20 , and the fourth reinforcement structure 22 represents the transverse reinforcement structure corresponding to the second base 20 .

[0058] The embodiment of the present application can improve the bearing capacity of the first base 10 and the second base 20 through a plurality of reinforcement structures, thereby further improving the safety of the packaging structure.

[0059] In an exemplary embodiment, Figure 3 and Figure 4 As shown, the first opening surface 13 is provided with an opening 14, and the second opening surface 23 is provided with a clamping member 24. When the first structure and the second structure are combined, the clamping member 24 is clamped into the opening 14 to fix the first structure and the second structure.

[0060] Specifically, the opening 14 is disposed at the first opening surface 13 , and the clamping member 24 is disposed at the second opening surface 23 . When the first structure and the second structure are combined, the opening 14 and the clamping member 24 can be fixed together.

[0061] Optionally, a folding device is provided between any side of the first opening surface 13 and a side of the second opening surface 23 corresponding to said any side. For example, the folding device may be a hinge, and the first structure and the second structure are connected by the hinge so that the first structure and the second structure can be folded by the hinge, thereby facilitating the combination of the first structure and the second structure.

[0062] The embodiment of the present application can combine the first structure and the second structure through the opening 14 and the clamp 24 to prevent the first structure and the second structure from loosening during transportation, causing the target fragile goods to fall, thereby improving the safety of the packaging structure.

[0063] In an exemplary embodiment, the first film 30 is bonded to the first opening surface 13 by hot-melt bonding, and the second film 40 is bonded to the second opening surface 23 by hot-melt bonding. Hot-melt bonding can improve the bonding stability between the first film 30 and the first opening surface 13, and improve the bonding stability between the second film 40 and the second opening surface 23.

[0064] In an exemplary embodiment, the material of the first base 10 and the second base 20 is pulp molding. The first base 10 and the second base 20 are pulp molded bases. The pulp molded base is made by semi-wet pressing. Specifically, using pulp molding as a material can reduce the cost and weight of the packaging structure and improve transportation efficiency. The semi-wet pressing method can improve the bearing capacity of the base and ensure the safety of the packaging structure.

[0065] In an exemplary embodiment, the first film 30 and the second film 40 are made of one of TPU, PE, and PVC. Specifically, the load-bearing capacity and stretchability of the above materials can improve the stability of the package.

[0066] In an exemplary embodiment, ventilation holes are provided on the first film 30 and the second film 40. Specifically, the ventilation holes can be generated by laser minimally invasive perforation, and the freshness preservation performance can be improved through the ventilation holes.

[0067] In an exemplary embodiment, Figure 7 The figure is a schematic diagram of the structure of a packaging box for fragile goods in an embodiment of the present application. The packaging box includes a box body 60 and a packaging structure as described in the above embodiment arranged inside the box body.

[0068] Specifically, the size of the box 60 corresponds to the size of the packaging structure, that is, the size of the box 60 is a multiple of the size of the packaging structure, so that at least one packaging structure can be placed in the box 60 without leaving any remaining space so that the packaging structure slides in the box during transportation. The packaging structure can be loaded in the packaging box, thereby improving transportation safety.

[0069] In one example, the box body 60 may be a carton, and the structure of the carton may be a double pit. The box body 60 may be a heat preservation box, which is used to reduce the temperature fluctuation in the box.

[0070] In an exemplary embodiment, the specific implementation of the packaging structure of the perishable goods is as follows:

[0071] In view of the problems of existing grape packaging: 1. Grape bunches are of different shapes and sizes; 2. Most of the current packaging is bag-in-bag, which is light and large after packaging; 3. The existing bag-in-bag packaging requires the use of inflation equipment, and the inflation strength and pressure are difficult to control; 4. The current packaging requires the addition of foam boxes, ice bags and other materials. Based on the above problems, a packaging structure for fragile products is proposed. The specific packaging structure is as follows:

[0072] 1. Pulp molded tray:

[0073] 1.1 Structural design: By collecting the shapes and weights of different grape bunches, the structure of the pulp molded tray is designed according to the three-dimensional structure of the grape bunches. In addition, the structural design can be modeled through three-dimensional drawings. The pulp molded tray is mostly hollow in the middle, and the pulp molded tray can be used with a membrane; multiple reinforcing ribs can be set on the side of the pulp molded tray to provide support.

[0074] 1.2 Material and process: According to the detection and multiple tests of grape respiration intensity, pulp molding can use corrugated pulp and semi-wet pressing. Among them, the cost of corrugated pulp is low, the appearance precision of semi-wet pressing is close to that of wet pressing, the fiber damage is small, the density is high, and the product toughness and strength are high.

[0075] 2. Membrane:

[0076] 2.1 Material: Thermoplastic resin film, the material can be TPU, PE, PVC and other materials.

[0077] 2.2 Technical parameters: The film is tested for resilience and strength based on the grape respiration intensity and the weight of a single bunch of grapes. The tensile strength must be no less than 18MPa in the longitudinal direction and 14MPa in the transverse direction.

[0078] 2.3 The above film materials all have low viscosity, and laser minimally invasive perforation can be used to set air holes in the film, and the air holes can be used to adjust the freshness-keeping performance.

[0079] 3. Combination of pulp molding and membrane:

[0080] The membrane is laminated around the pulp mold by hot-melt method. The height between the lowest point of the membrane after bearing the pressure of the grapes and the bottom of the pulp mold can be 3 to 4 centimeters.

[0081] 4. Configure outer cartons of appropriate sizes according to actual needs. The outer carton should be double-pitted, with an edge pressure of no less than 4.3KN / m and a tear resistance of no less than 800KPa. When the external ambient temperature is high and temperature control is required, use insulated cartons to reduce temperature fluctuations inside the box.

[0082] The embodiments of the present application can fully wrap and fix grape bunches of different shapes and sizes, restricting them from shaking and touching in the packaging box, and can solve the cargo damage problem caused by the grape bunches squeezing and colliding with each other and the grape berries falling off due to turning upside down during the logistics process. The packaging structure does not need to use ice bags and foam boxes, and can effectively reduce the cost of packaging materials. The packaging structure does not need to use bags in bags, effectively reduces the light throwing of materials and does not need to carry inflation equipment, which is convenient for packaging operations at the place of production. The packaging structure has high packaging efficiency, and the packaging materials involved in the packaging have a small physical volume before use, low storage and transportation costs, and good portability.

[0083] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
