Abstract

A carton ventilation structure is that a carton is respectively provided with two opposite long-side top covers, two short-side top covers, two long-side bottom covers, and two short-side bottom covers. The ventilation holes form the top surface and bottom surface of the carton after the box cover is folded horizontally, so that the long-side top cover and the short-side top cover of the top surface overlap, and the long-side bottom cover and the short-side bottom cover of the bottom overlap. The ventilation holes are aligned correspondingly, and the ventilation holes on the top surface and bottom surface of the carton are also aligned up and down; when the cartons are stacked up and down and the cartons of the spacer layers are stacked in a 90-degree horizontal rotation, make each layer The ventilation holes of the carton are connected and staggered together, so that the air can flow directly from the top layer of the carton to the bottom layer of the carton, so that each layer of each carton can maintain a good ventilation effect.

Description

The ventilation structure of the carton

The utility model relates to a box cover which is folded horizontally on the top surface and the bottom surface of the carton box, and is provided with ventilation holes corresponding to and aligned with the upper and lower sides, and the spacer layer carton of the upper and lower stacked carton boxes is at a level of 90 degrees. When rotating and overlapping, let the ventilation holes on the top and bottom surfaces of adjacent layers of cartons be staggered together so that the air can flow vertically between the stacked cartons.

The conventional structure of a carton 1 with a box cover, as shown in Figure 1, the side of the box body of the carton 1 is respectively provided with ventilation holes 15, 16, and the upper and lower sides of the carton 1 are respectively provided with two opposite long-side top covers 11 and two. The short-side top cover 12 and the opposite two long-side bottom covers 13 and two short-side bottom covers 14 are provided.

As shown in Figure 2, the top and bottom surfaces of the carton 1 are respectively formed by folding the upper and lower sides of the box cover horizontally. An opening for air circulation is formed in the middle of the top surface of the carton 1. The width of the bottom covers 13 on the two long sides is exactly half of the short sides of the carton 1, so that the bottom surface of the carton 1 is in a closed state.

Therefore, as shown in Figure 3, when the cartons 1 are arranged next to each other and stacked up and down, in order to make the stacked cartons 1 stably stacked together, the adjacent layers of cartons 1 are usually placed at a level of ninety degrees. Rotate and overlap the other layers of cartons 1, so that the top surfaces of the middle and lowermost cartons 1 are closed by the bottom surfaces of the adjacent upper cartons 1.

Therefore, in addition to the middle of the top surface of the uppermost carton 1, there is still room for air circulation. Except for the opening, the top surfaces of the other layers of the carton are closed, and the ventilation can only be carried out in the horizontal direction through the ventilation holes 15 and 16. Especially the ventilation effect of the carton in the middle will be greatly reduced. When there are fully mature fruits and vegetables in the carton, under the above-mentioned poor ventilation, even if it is refrigerated or transported at low temperature, there will still be a problem of very easy spoilage.

The reason is that, in order to improve the ventilation holes on the aforementioned known carton, after the upper and lower layers of the carton are stacked, the problem of spoilage of fresh goods will easily occur due to poor internal ventilation. On the box cover together, there are ventilation holes aligned with the top and bottom, and after the carton of the spacer layer is rotated 90 degrees horizontally and stacked with the carton of the adjacent layer, the air between the top surface and the bottom surface of the adjacent carton is The ventilation holes are also staggered together, so that the air can be ventilated in the vertical direction between the layers, so that the inner carton in the middle of the multi-layer arrangement can still maintain a good ventilation effect, so that the low-temperature refrigeration or transportation of fresh items The saving effect is optimized.

The technical solution adopted by the new model to solve the technical problem is as follows: a carton is respectively provided with two opposite long-side top covers, two short-side top covers and two long-side bottom covers, two short-side top covers and two short-side top covers, which can be folded horizontally to form a top surface and a bottom surface. Bottom cover, so that each long side top cover, short side top cover and long side bottom cover, short side bottom cover are respectively provided with several ventilation holes, and the ventilation holes on the top surface and bottom surface of the carton after horizontal folding are in the shape of When the top and bottom are aligned with each other, and when the upper and lower spacer carton boxes are stacked in a 90-degree horizontal rotation, the top and bottom surfaces of the adjacent stacked upper and lower cartons can still be aligned. The ventilation holes between them are interconnected and staggered together.

Therefore, through the ventilation holes opened on the cover of the new carton box, when the upper and lower adjacent layers of cartons are rotated and overlapped horizontally at 90 degrees, the ventilation holes at the overlapped place can be staggered and connected, so that After stacking, the cardboard box in the middle can also keep the air flowing up and down smoothly, so that the packaging can be fresh. Fresh content items have better preservation effect when refrigerated or transported at low temperature.

Please refer to Figs. 4 and 5. The sides of the new carton 1 are respectively provided with ventilation holes 15, 16, and the upper and lower peripheries of the carton 1 are respectively provided with two opposite long-side top covers 11 and two short-side top covers 12 is the box cover with the opposite two long side bottom covers 13 and two short side bottom covers 14.

The long-side top cover 11 , the short-side top cover 12 , the long-side bottom cover 13 , and the short-side bottom cover 14 of each box cover are provided with several ventilation holes 17 . After each box cover on the carton 1 is folded horizontally, make the ventilation holes 17 between the long-side top cover 11 and the short-side top cover 12, and the ventilation holes between the long-side bottom cover 13 and the short-side bottom cover 14. The holes 17 are all aligned correspondingly, and the above-mentioned ventilation holes 17 formed by the top surface and the bottom surface of the carton 1 are also vertically corresponding and aligned with each other.

Please refer to picture 6, when the top and bottom of carton 1 are stacked together, the spacer The carton 1 is rotated 90 degrees horizontally and is stacked with the carton 1 of the adjacent layer; as shown in Figure 7, the ventilation holes on the top surface of the lower carton 1 that are stacked together on the adjacent upper and lower layers. 17, and the ventilation holes 17 on the bottom surface of the upper carton 1 are staggered together while still maintaining communication.

Therefore, as shown in Fig. 8, the ventilation holes 15 and 16 on the side of the carton 1 can not only allow the air to circulate in the horizontal direction, but also the ventilation holes 17 between the adjacent upper and lower carton 1 stacked together. , so that the air can be circulated in the vertical direction; therefore, when the cartons 1 are stacked in multiple layers, the cartons 1 located in the middle of the stack pass through the ventilation holes 17 on the top and bottom surfaces of the cartons 1 to allow the air to circulate smoothly. Especially when the carton 1 is filled with fresh contents, cold air can be quickly circulated in each carton during low-temperature refrigeration or transportation, so that the best freshness preservation effect can be exerted.
