[0014] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0015] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figure 1 and Figure 2 As shown, a lightweight carton involved in the present embodiment includes a carton body, which is made of lightweight paperboard. The lightweight paperboard includes a base paper 1 and a face paper 2. A corrugated paper 3 is arranged between the face paper 2 and the base paper 1. A connecting hole 4 in the shape of an "I" is opened on the corrugated paper 3. A first plug-in piece 5 and a second plug-in piece 6 that fit each other are arranged in the connecting hole 4. One end of the second plug-in piece 6 is connected to the base paper 1, and one end of the first plug-in piece 5 is connected to the face paper 2. A locking hole 7 is opened on the first plug-in piece 5, and a locking piece 8 is arranged on the second plug-in piece 6. The locking piece 8 is inserted into the locking hole 7.

[0018] Furthermore, the connection holes 4 are arranged on the corrugated paper 3 in a rectangular array.

[0019] Furthermore, the first inserting piece 5 is integrated with the surface paper 2 ; the second inserting piece 6 is integrated with the bottom paper 1 .

[0020] In this embodiment, the first plug-in piece 5 and the second plug-in piece 6 corresponding to the same connecting hole 4 are both inserted into the connecting hole 4, and the locking piece 8 on the second plug-in piece 6 is inserted into the locking hole 7 of the first plug-in piece 5, so as to realize the connection between the first plug-in piece 5 and the second plug-in piece 6, and the connection between the corrugated paper 3 and the base paper 1 and the face paper 2.

[0021] Example 2

[0022] See also Figure 1 and Figure 2 As shown, the lightweight carton involved in this embodiment is further configured on the basis of Embodiment 1 so that the extending direction of the corrugations on the corrugated paper 3 is perpendicular to the extending direction of the length of the connecting hole 4 .

[0023] In this embodiment, by setting the extension direction of the corrugations on the corrugated paper 3 to be perpendicular to the length extension direction of the connecting hole 4, the corrugated paper 3 cannot be unfolded in a direction perpendicular to the extension direction of the corrugations, thereby enhancing the impact resistance of the corrugated paperboard.

[0024] Example 3

[0025] See also Figure 1 and Figure 2 As shown, the lightweight carton involved in this embodiment is further configured on the basis of Embodiments 1 and 2, and the base paper 1 and the surface paper 2 are provided with material-saving holes 9.

[0026] In this embodiment, the mass of the base paper 1 and the face paper 2 is reduced by opening the material-saving hole 9, so that the mass of the manufactured corrugated board is smaller, and the mass of the carton manufactured using the corrugated board is also smaller.

[0027] The lightweight carton involved in the utility model does not use adhesive to achieve the connection between the corrugated paper, the face paper and the bottom paper, thereby reducing the weight of the unit corrugated cardboard and making the manufactured box body lightweight; the weight of the corrugated cardboard is further reduced by opening the material-saving holes, and the overall function is perfect and the practicability is strong.
