Description

Technical Field

[0001] The utility model relates to fruit and vegetable packaging in the technical field of food packaging, in particular to an adaptive foam filling structure for packaging. Background Art

[0002] In the processing of fruits and vegetables, packaging is usually required after basic processes such as picking, cleaning, and removing impurities. It is mainly used to protect the integrity and freshness of fruits and vegetables during transportation and storage. In actual applications, merchants choose appropriate foam packaging materials and specifications according to different fruit and vegetable characteristics and market demand, and also optimize the packaging structure design to further improve the safety and quality of fruits during transportation.

[0003] Among them, for some fruits and vegetables that are soft and tender, easily damaged by knocks, require a long time to transport, are expensive, and have special value (such as yellow peaches, kiwis, mangoes, and tomatoes), their packaging structure usually needs to have basic properties such as waterproof, shockproof, and pressure-proof to ensure that the aforementioned fruits and vegetables will not be damaged during transportation. For the aforementioned types of fruits and vegetables with spherical or quasi-spherical individual shapes, the commonly used packaging treatment method is to use soft materials such as foam and pulp boards to prepare a bottom tray, and then evenly open placement holes on the bottom tray to place the individual fruits and vegetables, and stack multiple bottom trays in the placed state before packaging; this packaging method has a certain protective effect, but the defect is that there are differences between individual fruits and vegetables, which causes the placement holes of the bottom tray to be unable to adapt well to individual fruits and vegetables of different sizes and shapes. When placing individual fruits and vegetables, it may cause some smaller fruits and vegetables to have a larger gap between the placement holes, making the overall stability after packaging poor, and it is easy to shift or break due to shaking or collision during transportation.

[0020] Among them: 1. bottom support; 2. cover body; 3. kiwi fruit; 4. inflatable interlayer; 5. positioning step groove; 6. tooth-shaped protrusion; 7. convex arc surface; 8. convex step surface; 9. cover and lid closing position; 10. receiving groove. DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0022] See also Figure 1 A preferred embodiment of the adaptive foam filling structure for packaging, in this embodiment, the adaptive foam filling structure for packaging is used as an inner packaging structure to package kiwi fruit 3, which includes a plurality of stacking units, and the structure of a single stacking unit is consistent, and all include a matching base 1 and a surface cover.

[0023] The base 1 is formed of EVA foam and has a structural thickness capable of providing stacked support. A circle of convex step surfaces 8 are formed on the outer edge of the base 1. The inner area of ​​the convex step surface 8 of the base 1 is used as a fruit and vegetable placement area. A plurality of receiving grooves 10 are evenly arranged in a dot matrix manner in the fruit and vegetable placement area. These receiving grooves 10 have a volume size larger than the largest kiwifruit 3 in the batch so as to be able to place all kiwifruits 3 in the batch. Each receiving groove 10 has a concave arc bottom surface so as to better fit the spherical shape of the kiwifruit 3, thereby increasing the stability of placement. The spacing between adjacent receiving grooves 10 on the base 1 is 1 / 3 of the volume groove size so as to ensure the supporting strength of the entire base 1.

[0024] In another embodiment, in order to improve the practicality of the base tray 1, a layer of lining material matching the base tray surface and the receiving groove can be formed on the surface of the fruit and vegetable placement area of ​​the base tray 1. The lining material is a removable and replaceable soft thin sheet structure, and different lining materials have different thicknesses at the receiving groove position. By replacing the lining material, the receiving groove 10 can adapt to the placement of smaller sized kiwifruits 3. At the same time, the lining material can also effectively improve the recyclability of the base tray 1. When the surface of the lining material is contaminated, the base tray 1 can be recycled and reused by replacing the corresponding lining material.

[0025] Taking into account that the kiwi fruits 3 placed in the receiving groove 10 have different sizes, some kiwi fruits 3 are still prone to rolling and bumping after being placed in the receiving groove 10, and a surface cover closing position 9 is reserved on the surface of the fruit and vegetable placement area on the inner side of the outer convex step surface 8 of the bottom tray 1; the surface of the fruit and vegetable placement area of ​​the bottom tray 1 can be covered with a surface cover at the surface cover closing position 9.

[0026] The cover is composed of a cover body 2. The cover body 2 and the base 1 are made of the same EVA foam material and are integrally formed to control costs. An inflatable interlayer 4 with an air nozzle is formed on the lower surface of the cover body 2. A plurality of adaptive filling structures matching the receiving groove 10 are formed on the lower surface of the inflatable interlayer 4. These adaptive filling structures include an inflatable portion, which is connected to the inflatable interlayer 4 on the inner side. The inflatable portion has an outer convex arc surface 7, and two tooth-shaped protrusions 6 arranged opposite to each other are formed on the outer edge of the outer convex arc surface 7. The two tooth-shaped protrusions 6 are correspondingly formed on both sides of the outer edge of the receiving groove 10; when the inflatable interlayer 4 is inflated, the cross-sectional size of the tooth-shaped protrusion 6 increases continuously from bottom to top to better accommodate kiwis 3 of different sizes.

[0027] In another embodiment, the tooth-shaped protrusion 6 can also be provided with a concave arc surface on the surface corresponding to the accommodating groove 10 side, and a layer of foam padding is installed on the surface of the concave arc surface to increase the fitting and protective effect on the surface of the kiwi fruit 3.

[0028] A positioning step groove 5 is formed on the bottom surface of the base 1, and the cover body 2 has a thickness greater than the height of the convex step surface 8, so that when the cover body 2 is covered in the cover closing position 9, the cover body 2 can be matched with the positioning step groove 5 at the upper position as a whole, so as to Figure 1 In the style shown, the structure covered with the cover on the surface of the base 1 can be stacked up and down through the positioning step groove structure, thereby realizing a stacking combination of multiple bases 1 and cover, thereby improving the space utilization of the packaging.

[0029] In another embodiment, in order to optimize the aforementioned stacking structure, the entire surface cover can be directly formed on the bottom surface of the upper base 1 to achieve stacking of multiple bases 1.

[0030] In actual application, the operator first inflates the inflatable interlayer 4 through the air nozzle to expand the adaptive filling structure and fit the shape of the kiwi fruit 3. Then, the kiwi fruits 3 are placed one by one in the receiving groove 10 of the bottom tray 1, and each kiwi fruit 3 is tightly wrapped by the adaptive filling structure. Next, the cover is placed on the bottom tray 1, and the positioning step groove structure is used to ensure that the cover and the bottom tray 1 are accurately aligned. Finally, multiple stacking units are stacked to form a complete packaging structure.

[0031] This adaptive foam filling structure for packaging is not only simple to manufacture and low in cost, but also can effectively package kiwifruit 3 with different individual sizes. Through the design of the adaptive filling structure, it can ensure that each kiwifruit 3 is tightly wrapped, reducing displacement and damage during transportation. At the same time, the cushioning protection of the foam material can also effectively reduce the damage to the kiwifruit 3 caused by external impact, thereby improving transportation efficiency and quality.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
