Technical Field

[0001] The utility model relates to the technical field of apple transportation and storage, in particular to an apple preservation paper box. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer are less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper.

[0003] In the prior art, when apples are transported, it is easy for the apples to collide with each other due to vibration, thus causing damage to the apples. In addition, the existing cartons for transporting apples are generally relatively closed on all sides, resulting in air being unable to circulate inside the cartons, resulting in the apples' own ethylene gas being unable to be released, causing the apples inside the cartons to be over-ripened, resulting in the apples rotting and deteriorating.

[0024] In this embodiment, two ventilation plates 2, a positioning plate 3, a carton bottom plate 1 and a carton top plate 6 together form a carton with a side opening, and the transverse slide grooves 21 and the positioning grooves 4 opened on the side walls of the ventilation plates 2 and the positioning plates 3 are used to install the placement plates 8, and the spacing between two adjacent placement plates 8 is equal. The support frame 9 is set for positioning. When placing apples, first, the placement plates 8 are inserted into the transverse slide grooves 21 and the positioning grooves 4, and then the bottom end of the apple is placed on the upper end of the support frame 9, and the other placement plate 8 is installed in the adjacent positioning groove 4. At this time, the bottom side of the support frame 9 inside the other placement plate 8 will contact the top of the apple, thereby achieving the effect of fixing the position of the apple, and through the setting of multiple support frames 9, the weight of the square apples is evenly distributed on each apple below, so that the gravity of the apples is dispersed, thereby achieving the effect of protecting the apples at the bottom.

[0025] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the inner wall of the ventilation plate 2 is provided with a plurality of transverse grooves 21, and the positions of the transverse grooves 21 correspond one-to-one to the positions of the positioning grooves 4. The outer wall of the ventilation plate 2 is provided with a plurality of longitudinal grooves 22, and the sum of the groove depths of the longitudinal grooves 22 and the groove depths of the transverse grooves 21 is equal to the thickness of the ventilation plate 2.

[0026] In this embodiment, by setting the transverse slide groove 21 and the longitudinal slide groove 22, ventilation holes are opened at the plate surface of the ventilation plate 2 where the transverse slide groove 21 and the longitudinal slide groove 22 are opposite to each other, and the position of the ventilation hole corresponds to the open end of the placement plate 8, thereby achieving the effect of facilitating the discharge of ethylene produced by the apples inside the carton.

[0027] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the groove width of the transverse sliding groove 21 is equal to the groove width of the positioning groove 4.

[0028] In this embodiment, the transverse sliding groove 21 corresponds to the position of the positioning groove 4 and the groove widths are set to be equal, so as to facilitate the installation of the placement plate 8.

[0030] In this embodiment, since the placement board 8 is formed by four pieces of cardboard connected to each other, the placement board is a rectangular hollow frame with openings at both ends. When the placement board 8 is installed inside the transverse slide groove 21 and the positioning groove 4, the open end of the placement board 8 corresponds to the position of the transverse slide groove 21. At this time, the two sides of the placement board 8 are embedded in the interior of the positioning groove 4 and provide support for the positioning groove 4, and the open end corresponds to the position of the ventilation hole, so that during the circulation of external air, air can pass through the interior of the placement board 8. Since the top wall and the bottom wall of the placement board 8 are provided with positioning holes 10 for installing the support frame 9, when the air flows through the placement board 8, the ethylene gas emitted by the apple itself can be brought out through the positioning holes 10.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the support frame 9 includes a connecting ring 91, and a solid cardboard 92 is arranged on the outer peripheral side of the connecting ring 91, and the solid cardboard 92 has two bending parts 93, and the two bending parts 93 are respectively inserted into the inside of the two positioning holes 10 corresponding to the top wall and the bottom wall of the placement plate 8.

[0032] In this embodiment, the connection ring 91 is used to fix and connect multiple solid cardboards 92 to each other. The two bending parts 93 are used to clamp the solid cardboards 92 inside the placement plate 8, and support the upper end wall and the bottom end wall of the placement plate 8 to avoid the placement plate 8 from collapsing. In addition, since the solid cardboards 92 are distributed in a circular array on the outer surface of the connection ring 91, the top of the solid cardboards 92 form a support plate to support the bottom of the apple, so that the pressure on the apple during storage is evenly distributed on the bottom of the apple, avoiding the problem of bruises on the apple.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a plug plate 11 is provided on one side of the movable paperboard 5 , and a slot 12 engaged with the plug plate 11 is provided on one side of the carton top plate 6 .
