Description

Technical Field

[0001] This utility model relates to the field of packaging material production technology, specifically to a cardboard box with irregularly shaped holes to prevent the handle from falling off. Background Technology

[0002] A cardboard box is a three-dimensional shape, composed of multiple facets that are moved, stacked, folded, and enclosed. In three-dimensional composition, facets divide space; cutting, rotating, and folding different facets creates different emotional expressions. When designing the display surfaces of a cardboard box, attention should be paid to the connections between the display surface, sides, top, and bottom, as well as the placement of packaging information elements.

[0003] Chinese patent CN214927475U discloses a bottom-hook die for milk cartons, which optimizes the existing bottom-hook die technology. By coordinating the use of the cutter and the pressure line, the flared opening caused by the carton during the production process is optimized, allowing the flap to be easily glued to the carton without folds, thus improving the production efficiency of milk cartons. The device is simple to operate and extremely practical.

[0004] When using the milk cartons mentioned above, the position or shape of the handle fixing slots on the milk cartons are not ergonomically designed, resulting in a poor grip and requiring users to exert considerable force to lift them. This is especially problematic when the cartons are full and heavy, causing inconvenience to consumers. Utility Model Content

[0005] The purpose of this invention is to provide a cardboard box with irregularly shaped holes to prevent the handle from falling off, in order to solve the above problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cardboard box with irregularly shaped holes to prevent handles from falling off includes a top inner panel, characterized in that: a reinforcing plate is symmetrically and rotatably connected to the top inner panel; one of the top inner panels has symmetrically shaped holes, and the other irregularly shaped hole is opened on the reinforcing plate; a handle plate is engaged in both of the irregularly shaped holes; and a front panel is rotatably connected to one side of the top inner panel.

[0007] Preferably, a bottom inner plate is rotatably connected to one side of the front panel, a left side plate is rotatably connected to one end of the front panel, and a left support plate is rotatably connected to the top of the left side plate.

[0008] Preferably, a left support plate is rotatably connected to the bottom end of the left side plate, and a back panel is rotatably connected to one side of the left side plate.

[0009] Preferably, a top outer plate is rotatably connected to one side of the back panel, and a handle slot is provided on the top outer plate.

[0010] Preferably, a bottom outer plate is rotatably connected to one side of the back panel, and a right side plate is rotatably connected to one end of the back panel.

[0011] Preferably, a right support plate is rotatably connected to the top of the right side plate, a right lifting plate is rotatably connected to the bottom of the right side plate, and one side of the right side plate is rotatably connected to one end of the front panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By flipping the symmetrical reinforcing plates on the top inner plate into the fitting groove, the surface of the reinforcing plate is made to fit with the surface of the top inner plate, and the irregular holes on the reinforcing plate are aligned with the irregular holes on the top inner plate. The two ends of the handle plate pass through the irregular holes of the two layers respectively. The inner convex edge of one side of the irregular hole will abut against the inner wall of the arc plate, so that the horizontal plates at both ends of the handle plate fit and engage with the surface of the reinforcing plate, thereby increasing the friction and preventing the handle from easily slipping or falling off during use. This makes it more stable and reliable for users to lift.

[0013] 2. By closely contacting the inner convex edge with the inner wall of the handle, the stress points are distributed, avoiding the tearing that may occur in traditional slots due to concentrated stress, thereby improving the overall load-bearing capacity of the structure.

[0018] Please see Figure 1-14This utility model provides a technical solution: including a top inner plate 100, characterized in that: a reinforcing plate 101 is symmetrically and rotatably connected to the top inner plate 100; one top inner plate 100 has symmetrical irregular holes 102; another irregular hole 102 is opened on the reinforcing plate 101; a handle plate 103 is snapped into each of the two irregular holes 102; a front panel 104 is rotatably connected to one side of the top inner plate 100; the reinforcing plate 101 has symmetrically opened fitting grooves, the shape of which is the same as that of the reinforcing plate 101; the irregular hole 102 is shaped by a straight line and a concave line, the two ends of which are connected by an arc; and the handle plate 103 is composed of an arc plate and horizontal plates at both ends.

[0019] Furthermore, a bottom inner plate 105 is rotatably connected to one side of the front panel 104, a left side plate 106 is rotatably connected to one end of the front panel 104, and a left support plate 107 is rotatably connected to the top of the left side plate 106.

[0020] Furthermore, a left support plate 108 is rotatably connected to the bottom end of the left side plate 106, and a back panel 109 is rotatably connected to one side of the left side plate 106.

[0021] Furthermore, a top outer plate 110 is rotatably connected to one side of the back panel 109, and a handle through groove 111 is provided on the top outer plate 110.

[0022] Furthermore, a bottom outer plate 112 is rotatably connected to one side of the back panel 109, and a right side plate 113 is rotatably connected to one end of the back panel 109.

[0023] Furthermore, a right support plate 114 is rotatably connected to the top of the right side plate 113, a right lifting plate 115 is rotatably connected to the bottom of the right side plate 113, and one side of the right side plate 113 is rotatably connected to one end of the front panel 104.

[0024] Working principle: such as Figure 2 The front panel 104 drives the top inner panel 100 and bottom inner panel 105 on both sides to rotate along the left side panel 106 at one end. The back panel 109 drives the top outer panel 110 and bottom outer panel 112 on both sides to rotate along the left side panel 106 at one end. The rotation directions of the front panel 104 and the back panel 109 are opposite, so that the front panel 104 and the back panel 109 on both sides of the left side panel 106 are symmetrical and aligned. When the back panel 109 drives the top outer panel 110 and bottom outer panel 112 on both sides to rotate along the left side panel 106 at one end, it will also drive the right side panel 113 at the other end of the back panel 109 to move together, so that the right side panel 113 drives the right support plate 114 and right lifting plate 115 at both ends to rotate together with the back panel 109. When the front panel 104 and the back panel 109 are flush at both ends, the left side panel 106 is connected to one end of the front panel 104 and the back panel 109. By rotating the right side panel 113 at the other end of the back panel 109, the right side panel 113 is rotated along one end of the back panel 109 toward the other end of the front panel 104. By using glue, one side of the right side panel 113 is connected to the other end of the front panel 104, so that the front panel 104, the left side panel 106, the back panel 109 and the right side panel 113 are connected end to end to form a rectangle, so that the right side panel 113 at one end is symmetrically flush with the left side panel 106 at the other end. After forming a rectangle, rotate the left support plate 108 at the bottom of the left side panel 106 to flip it inward into the rectangle, and then rotate the bottom inner plate 105 on one side of the front panel 104 to flip it inward into the rectangle, so that one end of the bottom inner plate 105 covers the surface of the left support plate 108 and they are glued together. Rotate the right support plate 115 at the bottom of the right side panel 113 to flip it inward into the rectangle, so that the right support plate 115 obstructs the surface of the bottom inner plate 105 and they are glued together. Rotate the bottom outer plate 112 on one side of the back panel 109 to flip it inward into the rectangle, so that the bottom outer plate 112 obstructs the surface of the right support plate 115 and they are glued together to fix them. After the rectangular bottom surface is fixed, the symmetrical reinforcing plates 101 on the inner top plate 100 are flipped into the fitting grooves, so that the surface of the reinforcing plates 101 is in contact with the surface of the inner top plate 100, and the irregular holes 102 on the reinforcing plates 101 are aligned with the irregular holes 102 on the inner top plate 100. The transverse plates at both ends are rotated to be horizontal with the curved plate, so that they are inserted into the irregular holes 102 at both ends respectively. The two ends of the handle plate 103 pass through the two layers of irregular holes 102 respectively, so that the transverse plates at both ends of the handle plate 103 are in contact with the surface of the reinforcing plates 101 and snapped together. Flip the left support plate 107 at the top of the left side panel 106 and the right support plate 114 at the top of the right side panel 113 inwards into the rectangle. Then flip the top inner plate 100 that drives the handle plate 103 inwards into the rectangle, so that the two ends of the top inner plate 100 cover the right support plate 114 and the left support plate 107. Use glue to stick them together and fix them. By rotating the top outer plate 110 on one side of the back panel 109 inwards into the rectangle, the handle plate 103 on the top inner plate 100 passes through the handle through slot 111 through the top outer plate 110, so that the top outer plate 110 obstructs the top inner plate 100.

[0025] In the prior art, in conventional boxes, the handles are flattened and stuck together during long-term stacking and transportation, causing them to fall out of the holes. However, in this utility model, the inner convex edge on one side of the irregular hole will abut against the inner wall of the arc plate, preventing the handle from sticking together and thus avoiding the handle from falling out of the irregular hole.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
