[0002] Cardboard boxes are an indispensable part of our lives. To meet the needs of industrialization, sealing machines are now widely used to quickly seal the bottom of connected cardboard boxes for storing goods. Traditional manual sealing is flexible and can be solved by controlling the force. However, mechanical equipment is difficult to control the force during the sealing process, which can easily lead to damage to the cardboard box, especially at the connection between the main box panel and the side box panel. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a carton structure that facilitates mechanical sealing, which can reduce carton damage caused by mechanical bottom sealing and improve the yield rate.

[0004] According to an embodiment of the present invention, a carton structure for easy mechanical sealing is formed by folding a thin sheet of material. The vertical folding sequence comprises a connecting plate, a first main box panel, a first side box panel, a second main box panel, and a second side box panel. The first main box panel and the second side box panel are connected at their ends by a connecting plate to form a box shape. The first main box panel has a first upper main cover and a first lower main cover at its upper and lower ends, respectively. The first side box panel has a first upper side cover and a first lower side cover at its upper and lower ends, respectively. The second main box panel has a second upper main cover and a second lower main cover at its upper and lower ends, respectively. All adjacent box panels and covers are foldable. The first lower main cover and the second lower main cover are connected... The structure is identical, including a beveled edge and a flat edge. The beveled edge of the beveled edge slopes inward from the outer periphery of the lower main cover of the beveled edge and intersects with the flat edge at a misalignment point. The width of the lower main cover at the misalignment point is equal to half the width of the side box plate. The width of the lower main cover of the flat edge is greater than half the width of the side box plate but less than the width of the side box plate. When sealing the box, the first lower main cover and the second lower main cover intersect and overlap at the misalignment point. The beveled edge is provided with a triangular bend to facilitate the entry of the lower side cover. The bend is provided with a hook point near the first main box plate, that is, the beveled edge of the first lower main cover is placed on the flat edge of the second lower main cover, and the beveled edge of the second lower main cover is placed on the flat edge of the first lower main cover.

[0005] The carton structure according to the present invention, which facilitates mechanical sealing, has at least the following beneficial effects: the bottom of the carton is sealed by the interlacing and overlapping of the first and second lower main cover plates, which is more stable than the conventional parallel cover plate structure and is less prone to the bottom of the carton opening; by providing a bending part on the inclined side to facilitate the entry of the lower cover plate, the damage to the carton caused by mechanical sealing is avoided, and the yield rate is improved.

[0006] According to some embodiments of this utility model, the carton sealing machine hooks and pulls the carton through the hook points. The first main carton panel and the second side carton panel of the carton are connected by a connecting plate to form a double-layer structure. The two hooks of the carton sealing machine hook the misaligned points of the upper and lower layers respectively and pull the double-layered carton into a rectangle.

[0007] According to some embodiments of this utility model, the hook point is a notch on the outside of the bending line of the bent part near the main box plate. The notch can also prevent the force of the bent part from damaging the corners of the lower main cover plate.

[0008] According to some embodiments of this utility model, the angle between the bending line of the bent portion and the lower edge of the main box plate is slightly larger than the angle between the edge of the stretched lower cover plate and the lower edge of the main box plate. The angle between the edge of the stretched lower cover plate and the lower edge of the main box plate is generally 45°, and the angle between the bending line of the bent portion and the lower edge of the main box plate is set to 45.5°. When pressing the lower cover plate, a certain elastic deformation is used to make the structure of the lower cover plate and the lower cover plate more stable.

[0009] According to some embodiments of this utility model, one of the two misaligned points is concave to facilitate interlocking.

[0010] According to some embodiments of the present invention, the upper edges of the first side panel and the second side panel are lower than the height of the first main panel, which facilitates the closing of the upper panel.

[0011] According to some embodiments of this utility model, the carton structure, in the vertical folding sequence, consists of a first main box panel, a first side box panel, a second main box panel, a second side box panel, and a connecting plate.

[0012] According to some embodiments of this utility model, the sides of the second lower main cover plate, the first upper side cover plate, the second upper side cover plate, the first lower side cover plate, the second lower side cover plate, and the connecting plate are all beveled, which facilitates the sealing machine to press them together.

[0020] This utility model embodiment proposes a carton structure that facilitates mechanical sealing. It is formed by folding a thin sheet of material, with the following vertical folding sequence: connecting plate-5, first main box plate-1, first side box plate-3, second main box plate-2, and second side box plate-4. The first main box plate-1 and the second side box plate-4 are connected at the ends by the connecting plate-5 to form a box shape. The first main box plate-1 has a first upper main cover plate-11 and a first lower main cover plate-12 at its upper and lower ends, respectively. The first side box plate-3... The lower ends are respectively provided with a first upper side cover plate -31 and a first lower side cover plate -32; the upper and lower ends of the second main box plate -2 are respectively provided with a second upper main cover plate -21 and a second lower main cover plate -22; the upper and lower ends of the second side box plate -4 are respectively provided with a second upper side cover plate -41 and a second lower side cover plate -42, and all adjacent box plates and covers are foldable; the first lower main cover plate -12 and the second lower main cover plate -22 have the same structure, including a beveled edge -122 and a flat edge -121, the beveled edge The hypotenuse of section-122 slopes inward from the outer periphery of the lower main cover of the hypotenuse section-122, intersecting with the flat section-121 at the staggered point-13; the width of the lower main cover plate at the staggered point-13 is equal to half the width of the side box plate; the width of the lower main cover plate of the flat section-121 is greater than half the width of the side box plate but less than the width of the side box plate; when sealing the box, the first lower main cover plate-12 and the second lower main cover plate-22 intersect and overlap at the staggered point-13, and the hypotenuse section-122 is provided with a mechanism to facilitate the lower side... The bend-15 where the cover plate enters seals the bottom of the box by intersecting and stacking the first lower main cover plate-12 and the second lower main cover plate-22. Compared with the conventional parallel cover plate structure, it is more stable and less prone to the bottom of the box opening. The bend-15 on the inclined side-122 facilitates the entry of the lower cover plate. The bend-15 near the first main box plate-1 has a hook-16 to avoid damage to the carton caused by mechanical sealing and improve the yield rate.

[0021] It is understandable that the first lower main cover plate -12 and the second lower main cover plate -22 are intersected and stacked at the staggered point -13 in the following manner: the sloping side -122 of the first lower main cover plate -12 is placed on the flat side -121 of the second lower main cover plate -22, and the sloping side -122 of the second lower main cover plate -22 is placed on the flat side -121 of the first lower main cover plate -12, and vice versa.

[0022] In this embodiment, the carton sealing machine hooks and pulls the carton through hook point-16. The first main carton panel-1 and the second side carton panel-4 of the carton are connected by the connecting plate-5 to form a double-layer structure. The two hooks of the carton sealing machine hook the hook points-16 of the upper and lower layers respectively to pull the double-layer carton into a rectangle. The push plate of the carton sealing machine fixes the position of the side carton panel of the carton, which facilitates the sealing of the lower cover.

[0023] In this embodiment, the hook point-16 is a notch on the outside of the bending line of the bending part-15 near the main box plate. This notch is used to prevent the force of bending part-15 from damaging the corners of the lower main cover plate.

[0024] In this embodiment, the angle between the bending line-14 of the bent portion and the lower edge of the main box plate is slightly larger than the angle between the edge of the stretched lower cover plate and the lower edge of the main box plate. The angle between the edge of the stretched lower cover plate and the lower edge of the main box plate is generally 45°. The angle between the bending line-14 of the bent portion and the lower edge of the main box plate is set to 45.5°. When pressing the lower cover plate, a certain elastic deformation is used to make the structure of the lower cover plate and the lower cover plate more stable.

[0025] In this embodiment, one of the two misaligned points -13 is concave to facilitate interlocking.

[0026] In this embodiment, the upper edges of the first side panel-3 and the second side panel-4 are lower than the height of the first main panel-1, which facilitates the closing of the upper panel.

[0027] In this embodiment, the carton structure, in the vertical folding order, consists of the first main box panel-1, the first side box panel-3, the second main box panel-2, the second side box panel-4, and the connecting plate-5.

[0028] In this embodiment, the sides of the second lower main cover plate-22, the first upper side cover plate-31, the second upper side cover plate-41, the first lower side cover plate-32, the second lower side cover plate-42, and the connecting plate-5 are all beveled, which facilitates the sealing machine to press them together.

[0029] When sealing the carton, the first main panel-1 and the second side panel-4 of the carton are first glued together by the connecting plate-5 to form a double-layer structure for later use. The two hooks of the sealing machine are used to hook the hook points-16 of the upper and lower layers respectively to pull the double-layered carton into a rectangle. The push plate of the sealing machine fixes the position of the side panel of the carton, which facilitates the sealing of the lower cover. The sealing bottom component of the sealing machine bends the first lower main cover 12 and the second lower main cover 22 towards the bottom. During the bending, the elastic deformation of the carton material is used to make the flat side tilt forward and the side tilt backward through the sealing bottom component, so that the first lower main cover 12 and the second lower main cover 22 are staggered and stacked. The bending part-15 is bent at a certain angle along the bending line 14 by the sealing bottom component, and the lower side cover is folded into the bottom of the lower main cover. The bending part-15 is smoothed to complete the sealing of the bottom of the carton.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
