Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a corrugated paper box with improved compression resistance. Background Art

[0002] Corrugated paperboard is a common and widely used packaging product, which has penetrated into every aspect of our daily life. Because of its extremely wide range of applications, its usage has always been at the forefront of various packaging products.

[0003] In order to facilitate the placement of items, the upper end of the existing corrugated cardboard is generally set to an open structure in the initial state. After the items are placed, multiple covers are stacked and matched, and the covers are limited by tape to complete the sealing work of the upper end of the carton.

[0004] Therefore, in actual use, although the adhesive effect of the tape allows the covers to limit each other and provide a certain degree of deformation resistance, when the covers are subjected to downward impact force, the part of the covers that is subjected to upward support force is too small. Therefore, the covers will still deform, and the covers will be embedded in the carton, thereby destroying the overall structure of the carton.

[0005] Therefore, we believe that there is a need for a corrugated box that can increase the cover support portion. Summary of the invention

[0006] In view of the shortcomings of the prior art, the utility model proposes a corrugated paper box with improved compressive resistance, which has the advantage of increasing the supporting part for the cover, thereby preventing the cover from deforming toward the inside of the carton, and solving the problem of the prior art device that the support part of the cover is too small, which inevitably causes deformation of the carton when impacted.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Please refer to Figure 1-3 A corrugated paper box 1 with improved compression resistance includes a paper box 1 similar to a traditional structure. The unfolded view of the paper box 1 is a cross-shaped structure, which allows the paperboard to be directly cut and formed by a corresponding cutting mechanism, and then folded to form the paper box 1, thereby reducing the overall cost.

[0024] Therefore, the four side walls of the carton 1 need to be fixedly connected to each other to ensure that the carton 1 can maintain its shape after being folded and does not fall apart and return to the carton 1.

[0025] It should be noted that the difference between the present device and the common corrugated cardboard box 1 on the market is that the unfolded view of the cardboard box 1 of the present device is a cross-shaped structure, and the fixing process requires that the adjacent side walls be fixed separately, while the overall unfolded view of the traditional cardboard box 1 is a rectangular structure, and the main process only requires fixing the two ends of the rectangle in the middle section to form a rectangular structure connected end to end.

[0026] In practice, although this device has more fixing times than traditional technical devices, there is no gap between the bottom plate of the carton 1 and the four side walls of the carton 1, and they are formed in one piece. This makes the carton 1 as a whole more resistant to impact and deformation than the segmented combination fixation in traditional devices.

[0027] At the same time, by constraining the cross-section of the four side walls of the carton 1 to be a U-shaped structure, and constraining the side wall corresponding to the width side of the carton 1 to be side wall I103, and the side wall corresponding to the length side of the carton 1 to be side wall II104, by embedding the side wall I103 into the U-shaped openings of the two side walls II104, the thickness of the connection between the side wall I103 and the adjacent side wall II104 can be made twice the thickness of the side wall II104. This makes the four edges on the side of the carton 1 have higher structural strength, thereby having a stronger ability to resist upper and lower pressures, and can avoid the carton 1 from being highly deformed during actual use.

[0028] Specifically, as shown in the figure, the device realizes the fixed connection between adjacent side walls through relative U-shaped fixing nails, which is a conventional technical means in this field. Glue can also be applied between the actual adjacent two side walls to enhance the integrity. This is a conventional technical means in this field and will not be elaborated in detail here.

[0029] It should be noted that in practice, the device forms a carton 1 with an open upper end through a bottom plate and four side walls. Therefore, in order to close the upper end of the carton 1, the device is fixedly connected to the upper end of each side wall with a cover. By stacking adjacent covers up and down and placing the opposite covers on the same horizontal plane, the upper end of the carton 1 can be closed using four covers. This is a conventional technical means for those skilled in the art and will not be elaborated on here.

[0030] It should be noted that, the present device defines the cover corresponding to the side wall Ⅰ103 as cover Ⅰ101, and the cover corresponding to the side wall Ⅱ104 as cover Ⅱ102, and cover Ⅰ101 is located below cover Ⅱ102, so that the positions of the two side walls Ⅱ104 can be constrained by embedding cover Ⅱ102 into the carton 1, thereby preventing the carton 1 from being transformed into a parallelogram structure when projected on the horizontal plane, and cover Ⅰ101 is located below cover Ⅱ102 so that cover Ⅰ101 can support cover Ⅱ102, thereby improving the pressure resistance of the present device.

[0031] At the same time, cover I101 corresponds to the width side of the carton 1 and cover I101 is located at the bottom. The shorter length of cover I101 can be used to improve its anti-deformation ability, thereby improving the supporting effect of cover I101 on cover II102.

[0032] Furthermore, the device is provided with a support plate Ⅰ5 with a right-angled triangle structure in the longitudinal section at the four corners of the lower end of cover Ⅰ101, and the position of cover Ⅰ101 is constrained by constraining the two right-angled sides of the support plate Ⅰ5 to abut against the side wall and the lower end surface of cover Ⅰ101 respectively. This can further enhance the supporting effect of cover Ⅰ101 on cover Ⅱ102 and prevent cover Ⅰ101 from being mostly immersed in the inner wall of carton 1 and losing its supporting effect on cover Ⅱ102.

[0033] Furthermore, the device is provided with a support plate II2 at the upper end of the support plate I5, and the support plate I5 is in contact with the lower end surface of the cover I101 through the support plate II2, which can increase the contact area with the cover I101 and avoid deformation of the cover I101 due to a smaller area.

[0034] At the same time, the cross-section of the support plate Ⅱ2 of the present device is a right-angled triangle structure, and the two right-angled sides of the support plate Ⅱ2 are respectively abutted against the adjacent two side walls. This can further prevent the projection of the carton 1 on the horizontal plane from transforming into a parallelogram structure, thereby improving the carton 1's ability to resist deformation on the horizontal plane.

[0035] Furthermore, in order to reduce costs, the device has a positioning block Ⅰ3 fixedly connected to the upper end surface of each support plate Ⅰ5, and a corresponding positioning groove Ⅰ6 is opened for the positioning block Ⅰ3 on the support plate Ⅱ2 corresponding to each support plate Ⅰ5. This can realize a detachable connection between the support plate Ⅰ5 and the support plate Ⅱ2 by inserting the positioning block Ⅰ3 into the corresponding positioning groove Ⅰ6, so that the support plate Ⅰ5 and the support plate Ⅱ2 can be cut and processed separately, thereby reducing the processing cost.

[0036] At the same time, the width of the constraint positioning groove Ⅰ6 is smaller than the width of the positioning block Ⅰ3 so that the positioning block Ⅰ3 can have an interference fit with the corresponding support plate Ⅱ2, avoiding the lack of sufficient positioning of the support plate Ⅰ5, which causes the support plate Ⅰ5 to fail to function as expected.

[0037] Furthermore, in order to reduce costs, the device has a positioning block Ⅱ4 fixedly connected to the two right-angled sides of each support plate Ⅱ2, and a corresponding positioning groove Ⅱ7 is opened on the side wall of the carton 1 for the positioning block Ⅱ4. This can realize a detachable connection between the support plate Ⅱ2 and the carton 1 by inserting the positioning block Ⅱ4 into the corresponding positioning groove Ⅱ7, thereby reducing processing costs.

[0038] At the same time, as shown in the figure, the length of the positioning block Ⅱ4 constrained by the device is greater than the thickness of the side wall, which allows the positioning block Ⅱ4 to protrude from the positioning groove Ⅱ7, and the part of the positioning block Ⅱ4 protruding from the positioning groove Ⅱ7 can be bent, which can improve the positioning effect of the side wall on the positioning block Ⅱ4 and ensure that the position of the support plate Ⅱ2 does not change.

[0039] Similarly, the width of the constrained positioning groove II7 of the device is smaller than the width of the positioning block II4, which can achieve an interference fit between the positioning block II4 and the side wall, thereby improving the positioning effect of the side wall on the positioning block II4.

[0040] Furthermore, the device constrains that a plurality of support plates Ⅱ2 are arranged between adjacent side walls, and the plurality of support plates Ⅱ2 are arranged equidistantly from top to bottom. This can prevent the support plate Ⅱ2 detachably connected to the support plate Ⅰ5 from being positioned too high relative to the carton 1, thereby rendering the anti-deformation ability of the support plate Ⅱ2 on the carton 1 ineffective.

[0041] One point that needs to be emphasized is that in the utility model, the positioning block Ⅰ3 and the support plate Ⅰ5 are integrated, and the positioning block Ⅱ4 and the support plate Ⅱ2 are integrated, and the positioning block Ⅰ3 and the support plate Ⅰ5, the positioning block Ⅱ4 and the support plate Ⅱ2 are all made of corrugated cardboard, which can effectively reduce processing costs and material costs.

[0042] In actual use, the utility model:

[0043] First, the operator fixes the bottom plate to keep it still, and bends the four side walls by 90 degrees in sequence. At this time, the side wall I 103 is embedded in the side wall II 104.

[0044] Then, corresponding fixing parts are used to realize the fixed connection between the two ends of the side wall Ⅰ 103 and the side wall Ⅱ 104. At this time, the overall structure and appearance of the carton 1 are stable;

[0045] Afterwards, select a suitable number of support plates I5 and support plates II2, and insert the positioning blocks I3 into the corresponding positioning grooves I6 to ensure that the support plates I5 can abut against the lower end surfaces of the corresponding support plates II2;

[0046] Finally, select a suitable number of support plates II2, insert the positioning blocks II4 into the corresponding positioning grooves II7, and at this time, bend the parts of the positioning blocks II4 protruding from the positioning grooves II7 in sequence to completely fix the support plates II2.

[0047] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
