Abstract
Description
Technical Field
[0001] This utility model relates to a paper packaging box, and more particularly to a paper packaging box for holding fruits and vegetables. Background Technology
[0002] Currently, paper packaging boxes for fruits and vegetables are a variation of blister packaging boxes. They can be printed with text, patterns, and colors on the outer surface to enhance the quality of the packaging. However, ordinary paper packaging boxes usually use a detachable lid or a corrugated box structure. Detachable lids are prone to separation when taking them out, causing the fruits and vegetables inside to fall out and get damaged. Corrugated box structures are cumbersome to pack and open, and they are also prone to damage when opening, rendering them unusable. Utility Model Content
[0003] The purpose of this utility model is to provide a fruit and vegetable packaging paper box, and the technical problem to be solved is that it is easy to operate and has a simple structure.
[0004] To solve the above problems, this utility model adopts the following technical solution: a fruit and vegetable packaging box, including a box body and an integral lid. The box body includes a front end face, a rear end face, two side faces, and a bottom face. The lid is integrally connected to the upper edge of the rear end face. A protruding connecting part is provided on the upper edge of the front end face. A through hole is opened in the connecting part. An insertion fixing part adapted to the through hole is provided on the edge of the lid away from the rear end face. The insertion fixing part is arranged opposite to the through hole. The through hole is a trapezoidal hole, with the upper side of the through hole shorter than the lower side. The shape of the insertion fixing part is trapezoidal. The edge of the insertion fixing part away from the lid is longer than the edge of the insertion fixing part connected to the lid, so that the left and right ends of the insertion fixing part form wings that gradually shrink towards the lid. When the lid is rotated downward to close, the insertion fixing part moves downward from above the connecting part and passes through the through hole. When the lid is reset and springs back upward, the upper surface of the insertion fixing part abuts against the upper edge of the through hole. The two wings are restricted by the upper ends of the waists on the left and right sides of the through hole and cannot disengage, thus realizing the lid closing on the box body.
[0005] Furthermore, the edge of the cover away from the rear end face is provided with a clearance groove to allow space for the connection part.
[0006] Furthermore, the cover has protruding edges extending to the upper edge of the front end face at both ends of the clearance groove to limit the position of the cover.
[0007] Furthermore, the connecting portion is inclined outward from the front end face so that the surface of the connecting portion opposite the rear end face forms a guide surface to guide the insertion fixing portion.
[0008] Furthermore, the connecting portion is inclined outward from the front end face so that the surface of the connecting portion opposite the rear end face forms a guide surface to guide the insertion fixing portion.
[0009] Furthermore, the connecting part is trapezoidal in shape, with the upper side shorter than the lower side.
[0010] Furthermore, the front end face, rear end face, two sides and / or the cover are provided with ventilation windows of different shapes.
[0011] Furthermore, at least the front end face of the box is an inclined surface that slopes towards the center of the box, and the inclination angle of the connecting part is the same as the inclination angle of the front end face.
[0012] Furthermore, the front end, rear end, and two sides of the box are all trapezoidal, so that they all tilt towards the center of the box after being folded into a box.
[0013] Furthermore, the front end face, rear end face, two sides and / or the cover are provided with ventilation windows of different shapes.
[0014] Compared with the prior art, this utility model has a protruding connecting part with a through hole on the front end face, and an insertion fixing part is provided at the end of the cover away from the rear end face. Both the through hole and the insertion fixing part are trapezoidal. When the cover is closed downwards, the insertion fixing part automatically pushes the connecting part outwards so that the insertion fixing part is inserted into the through hole. Through the cooperation between the two, the cover is placed on the box and cannot be detached by itself, so that the cover is closed on the box. It is easy to operate, and because it is achieved through its own structure, it is also simple in structure. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 and Figure 2 As shown, this utility model discloses a fruit and vegetable packaging box, including a box body 1 and an integral lid 2. In this utility model, the box body 1 and the lid 2 are made by cutting and splicing a whole piece of cardboard. The box body 1 includes a front face 11, a rear face 12, two side faces 13, and a bottom face 14. After cutting, the several faces of the box body 1 are only connected to the bottom face 14. The connection points are provided with indentations or intermittently cut grooves for folding and forming. The lid 2 is integrally connected to the upper edge of the rear face 12 to form a whole. The connection point between the lid 2 and the rear face 12 is also provided with indentations or intermittently cut grooves. An upwardly protruding part is provided on the upper edge of the front face 11. The connecting part 3 is integral with the front end face 11 to form a whole. The connecting part 3 has a through hole 31 that penetrates the surface of the connecting part 3. An insertion fixing part 21 that is adapted to the through hole 31 is provided on the edge of the cover 2 away from the rear end face 12. The insertion fixing part 21 is arranged opposite to the through hole 31. The through hole 31 is set as a trapezoidal hole, with the upper side of the through hole 31 being shorter than the lower side, so as to form a trapezoidal hole in a positive orientation. The shape of the insertion fixing part 21 is trapezoidal. The edge of the insertion fixing part 21 away from the cover 2 is longer than the edge of the insertion fixing part 21 connected to the cover 2, so that the left and right ends of the insertion fixing part 21 form wings 22 that gradually taper towards the cover 2.
[0025] like Figures 5 to 7 As shown, when the lid 2 is rotated downwards to close, the insertion fixing part 21 moves downwards from above the connecting part 3, causing the connecting part 3 to deform slightly. When the connecting part 3 reaches the lower edge of the through hole 21, the insertion fixing part 21 can pass through the through hole 31, the connecting part 3 returns to its original position, and when the lid 2 returns to its original position and springs back upwards, the upper surface of the insertion fixing part 21 abuts against the upper edge of the through hole 31. The two wings 22 are restricted by the upper ends of the waist on the left and right sides of the through hole 31 and cannot detach, thus closing the lid 2 onto the box body 1.
[0026] The above structure allows the operator to simply press down on the lid 2 to close it onto the body 1 without separating it, thus enabling quick boxing.
[0027] The connection between the front face 11, the rear face 12 and the two sides 13 can be made using existing technology, such as setting connecting ears at both ends of the front face 11 and the rear face 12, and fixing them to the two sides 13 by pasting the connecting ears or by using carton staples. No specific limitation is made here.
[0028] like Figure 4 As shown, in this utility model, the lower edge of the through hole 31 is slightly lower than the upper edge of the front end face 11, and the upper edge of the through hole 31 is slightly higher than the upper edge of the front end face 11. This ensures that after the insertion fixing part 21 is inserted into the through hole 31, the insertion fixing part 21 will not actively disengage from the through hole 31 unless an external force applies a pulling force to the connecting part 3 towards the outside of the box or a downward pressure to the cover 2. Figure 4 (As shown).
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a relief groove 121 is provided at the edge of the lid 2 away from the rear end face 12. The length of the relief groove 121 is equivalent to the length of the connecting part 3, so that the connecting part 3 can be avoided after the lid 2 is closed on the body 1. The width of the relief groove 121 can be slightly larger than the thickness of the connecting part 3. Specifically, the lid 2 is provided with protruding edges 122 extending to the upper edge of the front end face 11 at the left and right ends of the relief groove 121, so as to limit the lid 2, prevent the lid 2 from being damaged by excessive pressure, and improve the strength of the lid 2. In this way, the lid 2 will not collapse and damage the fruits and vegetables inside when stacked.
[0030] like Figures 5 to 7 As shown, in order to further facilitate the insertion and fixing part 21 to be smoothly guided into the through hole 31 when the cover 2 is rotated downwards to close, the connecting part 3 is set to be inclined to the outside of the front end face 11 so that the surface of the connecting part 3 opposite to the rear end face 12 forms a guide surface to guide the insertion and fixing part 21.
[0031] like Figure 4 As shown, the connecting part 3 is trapezoidal in shape, with its upper side shorter than its lower side, to reduce material usage. This design allows the connecting part 3 to avoid collisions with the clearance groove 121 on both sides of the clearance groove 121 during the downward rotation of the lid 2. Specifically, as shown... Figure 3 As shown, the length of the clearance groove 121 is slightly greater than the length of the lower part of the connecting part 3.
[0032] In this utility model, such as Figure 1 and Figure 2 As shown, the front face 11, rear face 12, two sides 13 and the lid 2 are all provided with ventilation windows 4 of different shapes. The ventilation window 4 on the lid 2 is rectangular and occupies most of the area of the lid 2, so that it is easy to select the fruits and vegetables inside through the ventilation window 4 on the lid 2. The ventilation windows 4 provided on the front face 11 and the two sides 13 are circular holes arranged in an array. The ventilation window 4 on the rear face 12 is rectangular and also has one that occupies most of the area of the rear face 12.
[0033] like Figures 1 to 4 As shown in this utility model, the front face 11, rear face 12, and two side faces 13 of the box body 1 are all trapezoidal, so that they tilt towards the center of the box body 1 after being folded into a box. The tilting direction is that the lower ends of the four faces tilt towards the center of the box body 1, so that the bottom area of the box body 1 is smaller than the opening area at the top of the box body 1. Of course, the lower side of the front face 11, rear face 12, and two side faces 13 is shorter than the upper side, so that when multiple fruit and vegetable packaging boxes are laid flat, there are gaps between them, which can prevent the ventilation windows 4 on the front face 11, rear face 12, and two side faces 13 from being blocked, and achieve the function of ventilation.
[0034] In this utility model, after folding into a box, the included angle between the front end face 11 and the bottom face 14, and the included angle j between the rear end face 12 and the bottom face 14, are 103°-105°. Figure 8 As shown, when the present invention is unfolded, the rear end face 12 is trapezoidal, wherein the two angles a adjacent to the cover 2 are 74°-76°, and the two angles b adjacent to the bottom face 14 are 100°-102°. The cover 2 is integrated with the rear end face 12. The front end face 11 is trapezoidal, wherein the two angles c adjacent to the bottom face 14 are 101°-103°, and the two angles d adjacent to the connecting part 3 are 75°-77°. The front end face 11 is integrated with the connecting part 3 and the bottom face 14. The connecting part 3 is trapezoidal. The two angles e of the connecting part 3 away from the front end face 11 are 124°-126°; the edge of the clearance groove 121 away from the fixing part 21 is a bevel, and the included angle f of the bevel is 123°-125°; the included angle g between the bevel of the fixing part 21 and the clearance groove 121 is 73°-75°; the side 13 is trapezoidal, and its short side is connected to the bottom surface 14 as a whole, and the two angles h of the side 13 and the bottom surface 14 are 103°-105°; the two angles i at the upper end of the through hole 31 are 129°-131°.
[0035] In this utility model, the box body 1 and the lid 2 can be cut from a single layer of corrugated cardboard, or they can be cut from cardboard such as cardboard, and their surfaces can be printed with patterns, etc.
[0036] This invention facilitates boxing operations, avoiding the need for aligning the lid with the box body before it can be closed, as is required with conventional lid-and-box designs. It also avoids the need to align the two inserts with the slots on both sides to fix the lid to the box body when using a box-like structure. This greatly reduces boxing time and complexity. Moreover, the relative fixation between the lid and the box body can be achieved simply through the cooperation of the connecting part and the insert fixing part. This invention also has the technical advantage of simple structure.
