[0020] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0021] like Figure 1-Figure 6 As shown, this embodiment provides a carton with internal cushioning foam, including a box body 1, a foam cushion 2 and a secondary cushioning body 3.

[0022] The box body 1 has an inner cavity, and the box body 1 includes a bottom plate 11, a first side plate 12, a second side plate 13, a third side plate 14, a fourth side plate 15 and an upper cover plate 16. The first side plate 12, the second side plate 13, the third side plate 14 and the fourth side plate 15 are respectively connected to the four sides of the bottom plate 11, and an upper cover plate 16 is formed at the outward ends of the first side plate 12, the second side plate 13, the third side plate 14 and the fourth side plate 15. A pressing groove is formed between the connected bottom plate 11, the first side plate 12, the second side plate 13, the third side plate 14, the fourth side plate 15, the first connecting plate 121, the second connecting plate 131 and the upper cover plate. The setting of the pressing groove makes the folding smoother. The first side plate 12 and the third side plate 14 are formed with first connecting plates 121 on both sides, and the second side plate 13 and the fourth side plate 15 are formed with second connecting plates 131 on both sides. The first connecting plate 121 is folded outward, and the second connecting plate 131 is folded toward the adjacent first connecting plate. The end of the second connecting plate 131 is folded toward between the first connecting plate 121 and the first side plate 12 or between the third side plate 14. Figure 6As shown, the first side panel 12, the first connecting panel 121 and the second connecting panel 131 located on the same side are connected, or the third side panel 14, the first connecting panel 121 and the second connecting panel 131 located on the same side are connected. Specifically, the first connecting panel 121 is provided with first adhesive strips 17 on both sides of the outward end, and the second connecting panel 131 is provided with second adhesive strips 18 on both sides of the outward end. The first connecting panel 121 and the second connecting panel 131 are connected in the above manner, so that the first connecting panel 121 can directly cover the gap generated when the first side panel 12, the second side panel 13, the third side panel 14 and the fourth side panel 15 are spliced, and the bonding is more secure after folding.

[0023] There are two foam cushion pads 2, each having a placement notch that penetrates the upper surface of the foam cushion pad 2 and one side wall thereof. The two foam cushion pads 2 are located in the inner cavity and are arranged opposite to each other. The length of the foam cushion pad 2 is less than half the length of the box body 1. When two objects are placed, a baffle can be set between the two foam cushion pads 2 to divide the inner cavity into two. There are mounting grooves 31 on the side walls and bottom walls of the placement notch of the foam buffer pad 2, and the secondary buffer body 3 is located in the mounting groove 31. The length of the secondary buffer body 3 is less than the depth of the mounting groove 31. The secondary buffer body 3 includes two circular plates 31, a spring 32 and a transparent annular belt 33. The two ends of the transparent annular belt 33 are fixedly connected to the circumference of the two circular plates 31. The transparent annular belt 33 is located between the two circular plates 31, and the spring 32 is located in the transparent annular belt 33. The secondary buffer body 3 is composed of the circular plate 31, the spring 32 and the transparent annular belt 33. The circular plate 31 is arranged to facilitate the connection of the secondary buffer body 3 and the mounting groove 31 by tape, and the transparent annular belt 33 is arranged to facilitate the observation of whether the spring 32 is damaged.

[0024] Another embodiment of the secondary buffer body 3 can be replaced by a rubber column or a silicone column.

[0025] This solution provides the first type of buffering protection by filling two foam buffer pads 2 into the inner cavity of the box body 1. The two foam buffer pads 2 are arranged opposite to each other. The inner circumference of the foam buffer pad 2 is provided with an installation groove 31. A secondary buffer body 3 is arranged in the installation groove 31. The existence of the secondary buffer body 3 can provide the second type of buffering protection. When the foam buffer pad 2 is in the impact resistance process, the foam buffer pad 2 will deform to provide primary buffering protection. When the deformation of the foam buffer pad 2 reaches the set value, the built-in object will touch the secondary buffer body 3 to provide secondary buffering protection.
