Description

Technical Field

[0001] The present invention relates to the technical field of logistics boxes, and in particular to a logistics carton with a built-in reinforcement frame. Background Art

[0002] In the logistics industry, cartons are commonly used packaging materials, and their quality and durability are directly related to the safety and integrity of the items inside. Traditional logistics cartons usually use a single cardboard structure. Although they are light, they have poor drop resistance. Especially when loaded with heavy objects such as fruits, they are easily deformed or broken by bumps and squeezing. In addition, traditional cartons have the following shortcomings in design and use:

[0003] Poor air permeability: For items that need ventilation to keep fresh (such as fruits), traditional cartons have poor air permeability, which can easily cause the items inside to deteriorate.

[0004] Easy to break when lifted: When buyers pick up express deliveries, they often habitually lift the carton through the ventilation holes on the carton, which will cause the carton to break at the stress point.

[0005] Unstable stacking: When multiple cartons are stacked, they are easily misplaced or collapsed due to mutual squeezing, affecting logistics efficiency.

[0006] In order to solve the above problems, various improved logistic cartons have appeared on the market. However, these cartons are often complex in structure, high in manufacturing cost, and still have some shortcomings in practical application. Therefore, it is particularly important to develop a logistic carton that has good ventilation, can effectively prevent cracking during lifting, and is stable in stacking. Summary of the invention

[0039] See also Figures 1 to 17 The present invention provides a technical solution: a logistics carton with a built-in reinforcement frame, comprising a carton enclosure 1, the left and right sides of the top and bottom surfaces of the carton enclosure 1 are integrally formed with a sealing plate 1, the front and rear sides of the top and bottom surfaces of the carton enclosure 1 are integrally formed with a sealing plate 2, after the sealing plate 1 2 and the sealing plate 2 3 block the box opening of the carton enclosure 1, the corresponding two sealing plates 2 3 are connected by a tape 4, and both ends of the tape 4 are bonded to the surface of the carton enclosure 1; thus, an ordinary logistics carton is formed.

[0040] Two reinforcing frames 5 are provided inside the carton enclosure 1, a support plate 6 is fixed between the two reinforcing frames 5, ventilation holes 7 are provided on the surface of the carton enclosure 1, perforations 8 are provided on the surface of the reinforcing frames 5, an assembling plate 10 is inserted into the inner ring surface of the reinforcing frames 5, a plastic sleeve 11 is fixed on the surface of the assembling plate 10, and the plastic sleeve 11 is inserted into the ventilation holes 7; there are four groups of ventilation holes 7, and the four groups of ventilation holes 7 are respectively distributed on the upper and lower sides of two parallel sides of the carton enclosure 1, each group of ventilation holes 7 is provided with two, the perforations 8 correspond to the ventilation holes 7 one by one, and the aperture of the perforations 8 is equal to the aperture of the ventilation holes 7 diameter; assembly grooves 9 are provided on the two parallel inner ring surfaces of the reinforcement skeleton 5, and the assembly plate 10 is inserted in the assembly groove 9. A through opening 20 is provided on the surface of the assembly plate 10, and the through opening 20 corresponds to the through hole 8. A screw 13 is screwed on the surface of the assembly plate 10, and one end of the screw 13 penetrates the assembly plate 10 and is screwed on the surface of the assembly groove 9. At this time, the plastic sleeve 11 penetrates the through hole 8 and the air vent 7; the aperture of the through opening 20 is smaller than the aperture of the through hole 8, and a rubber sleeve 12 is fixed to one end of the plastic sleeve 11. The rubber sleeve 12 is a "T"-shaped round tube, and one end of the rubber sleeve 12 is inserted into the through opening 20.

[0041] When in use, the air holes 7 are provided on the surface of the carton enclosure 1 so that when the logistics carton is filled with fruits, it is convenient to ventilate the interior of the box; and the frame composed of the reinforcement skeleton 5 and the support plate 6 is pushed into the carton enclosure 1, and the height of the frame is equal to the height of the carton enclosure 1, which effectively prevents the box from being bumped and deformed; in order to prevent the reinforcement skeleton 5 from falling off in the carton enclosure 1, the assembly board 10 is inserted into the assembly groove 9, at this time, the plastic sleeve 11 passes through the perforation 8 and the air hole 7, and the assembly board is fixed with screws 13 10 is fixed on the assembly groove 9, that is, the plastic sleeve 11 passes through the side plate of the carton enclosure 1 to prevent the reinforcement frame 5 from falling off, and when the purchaser picks up the express and takes the box, he usually habitually inserts two fingers into the two air holes 7 to lift the logistics carton. The traditional carton is easy to break between the two air holes 7 under the action of gravity of the fruits filled inside. After the assembly plate 10 is installed, two fingers are inserted into the two plastic sleeves 11, and the force point is the reinforcement frame 5, thereby preventing the carton enclosure 1 from breaking at the air holes 7.

[0042] The bottom surface of the reinforcement frame 5 is provided with a stacking groove 14, and the top surface of the reinforcement frame 5 is installed with a stacking strip 15. After two logistics cartons are stacked, the stacking strip 15 on the top of the lower logistics carton is inserted into the stacking groove 14 at the bottom of the upper logistics carton. The top surface of the stacking strip 15 is provided with a reserved hole 16, and the reserved hole 16 is a "T"-shaped circular hole. The inside of the reserved hole 16 is inserted with a screw 17, and the screw 17 passes through the reserved hole 16 and is screwed to the reinforcement frame. On the top surface of the frame 5, the width of the stacking groove 14 is equal to the width of the stacking strip 15; a notch 18 is provided on the end of the closing plate 2 close to the carton enclosure 1, and when the closing plate 2 is placed flat, the stacking strip 15 extends into the notch 18; a notch 2 19 is provided on the surface of the closing plate 23, and there are two notch 2 19. When the closing plate 23 is placed flat, the notch 2 19 is sleeved on the outside of the stacking strip 15, and the total thickness of the closing plates 12 and 23 after stacking is less than the height of the stacking strip 15.

[0043] During use, when multiple logistics cartons need to be stacked, stacking strips 15 are installed on the upper reinforcement frame 5, that is, the stacking strips 15 are fixed to the top surface of the reinforcement frame 5 through the reserved holes 16, and when the sealing plate 1 2 and the sealing plate 2 3 block the box opening of the carton enclosure 1, the notch 1 18 and the notch 2 19 avoid the stacking strips 15, and a length that can be pushed by the stacking strips 15 is reserved at the bottom tape 4. When two logistics cartons are stacked, the stacking strips 15 are inserted into the corresponding stacking grooves 14 to achieve the limitation of the two adjacent stacked logistics cartons; in this way, the reinforcement frame 5 cooperates with the support plate 6 not only to achieve the anti-fall reinforcement of the carton enclosure 1, and while the assembling plate 10 is used to fix the reinforcement frame 5 to the carton enclosure 1, the assembling plate 10 cooperates with the plastic sleeve 11 to act as an anti-rupture structure for fingers to pick up the logistics cartons; and the reinforcement frame 5 cooperates with the stacking strips 15 and the stacking grooves 14 to also meet the anti-bias limitation of the stacked logistics cartons.

[0044] The detailed usage process of the logistics carton with built-in reinforcement frame is as follows:

[0045] Assemble the reinforcement frame: Fix the support plate 6 between the two reinforcement frames 5 to ensure the stability of the frame. Install the stacking strips 15 on the top surface of the reinforcement frame 5 as needed, and fix it with the reserved holes 16 and screws 17. Place the reinforcement frame: Push the assembled reinforcement frame 5 and support plate 6 frame into the carton enclosure 1, and ensure that the height of the frame is consistent with the height of the carton enclosure 1. Install the assembly board: Insert the assembly board 10 into the assembly slot 9 of the reinforcement frame 5. Make sure that the plastic sleeve 11 passes through the perforation 8 and the air vent 7. Use screws 13 to fix the assembly board 10 to the assembly slot 9, and ensure that one end of the rubber sleeve 12 is inserted into the through-hole 20 to increase stability and protect fingers.

[0046] Sealing: Install the sealing plate 1 2 and sealing plate 2 3 on the left and right sides and the front and back sides of the top and bottom surfaces of the carton enclosure 1 to seal the box opening of the carton enclosure 1. Use tape 4 to connect the two corresponding sealing plates 2 3, and ensure that both ends of the tape 4 are bonded to the surface of the carton enclosure 1. During the sealing process, pay attention to the position of the notch 1 18 and notch 2 19 to ensure that they do not hinder the insertion of the stacking strip 15.

[0047] Stacking stage: When multiple logistics cartons need to be stacked, ensure that the upper logistics cartons have been installed with stacking strips 15. Insert the stacking strips 15 of the upper logistics cartons into the stacking slots 14 of the lower logistics cartons. Ensure that the stacking strips 15 and the stacking slots 14 fit tightly to achieve a limiting effect. Reserve a length at the bottom tape 4 that can be pushed by the stacking strips 15 to ensure that the tape will not tear during stacking.

[0048] Lifting the logistics carton: When the buyer needs to lift the logistics carton, two fingers can be inserted into the two plastic sleeves 11. Since the force point is the reinforcement frame 5, the carton enclosure 1 can be prevented from breaking at the vent hole 7.
