Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a recyclable and labor-saving buffer packaging for large-size refrigerators. Background Art

[0002] In recent years, with the improvement of the national living standard, consumers' functional requirements for household appliances have become more diverse. Driven by customer needs, the weight and volume of new refrigerator units have increased day by day, and the thickness of the buffer pads for refrigerator packaging and the size of cartons have also increased accordingly, resulting in an increase in the quantity of refrigerator packaging waste. At the same time, due to consumers' higher requirements for shopping experiences, the return and replacement rate of refrigerators is also rising. However, since the sum of the height of the refrigerator packaging and the height of the carton exceeds the threshold height of some residences, the carton can only be removed when it is damaged, thus increasing the risk of damage when the refrigerator is returned to the factory. In addition, when the porter moves the refrigerator from the buffer pad at its bottom to the ground, since a large-size refrigerator weighs up to one hundred kilograms, two workers are required to use a suction cup handle tool to lift and move the refrigerator by adsorbing on both sides of the refrigerator, and each worker has to bear at least fifty kilograms of weight, which places a great physical burden on the workers.

Specific embodiments

[0033] To make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Such as Figure 1 、 2As shown in the figure, a recyclable and labor-saving large-size refrigerator buffer packaging according to this embodiment includes an EPP buffer foam and a paper frame 5 arranged in sequence around the refrigerator for buffer protection. The EPP buffer foam includes a top buffer foam 1, an L-shaped edge protection buffer foam 2, a door protection buffer foam 3, and a bottom buffer foam 4, which buffer and protect the top, side edges, door, and bottom of the refrigerator respectively. The paper frame 5 is fixed by paper frame buckles 6 to protect the EPP buffer foam, so that the paper frame 5 can be opened in a limited space without being damaged. At the same time, the top of the paper frame 5 is covered with a carton top cover 7 for capping. A number of bundling straps 8 are arranged on the outer periphery of the bottom buffer foam 4, the carton top cover 7, and the paper frame 5 to prevent displacement or damage during transportation or handling. Two groups of parallel L-shaped carton edge protectors 9 and U-shaped carton corner protectors 10 are respectively arranged at the bottom of the paper frame 5. The bundling straps 8 respectively bypass around the L-shaped carton edge protectors 9 and the U-shaped carton corner protectors 10, and pass through the bottom buffer foam 4, the paper frame 5, and the carton top cover 7 to fix them. At the same time, the L-shaped carton edge protectors 9 and the U-shaped carton corner protectors 10 can also protect the edges of the bottom buffer foam 4, the paper frame 5, and the carton top cover 7 to increase the anti-breakage performance.

[0035] As Figure 3 shown, the top buffer foam 1 includes a top buffer pad corner protector 101 and a top buffer pad clearance structure 102. The thickness of the top buffer foam 1 is set to 35 mm. The length of the top buffer pad corner protector 101 is one-tenth of the length of the top buffer foam 1. The top buffer clearance structure 102 corresponds to the position of the radiator protrusion on the top of the refrigerator, so as to avoid the force being transmitted to the top of the refrigerator when the refrigerator is pressed or impacted at the top.

[0036] As Figure 4 shown, the L-shaped edge protection buffer foam 2 is provided with staggered edge protection buffer foam clearance structures 201 on both side surfaces. The edge protection buffer foam clearance structures 201 are a number of equally spaced and equally sized rectangular grooves, which can effectively reduce the impact and vibration on the refrigerator during transportation and handling. The thickness of the edge protection buffer foam 2 is the same as that of the top buffer foam 1. The length of the edge protection buffer foam clearance structure 201 is 1 / 5 of the length of the edge protection buffer foam 2, and the width is 5 / 6 of the width of the edge protection buffer foam 2.

[0037] As Figure 5 shown, the door protection buffer foam 3 is provided with a door protection clearance structure 301, which can effectively reduce the impact and vibration on the door during transportation and handling. The door protection clearance structure 301 includes a number of equally sized and equally spaced rectangular grooves in the middle of the door protection buffer foam 3, and rectangular grooves with the same length as the refrigerator door handle in the two edge regions of the door protection buffer foam 3.

[0038] As Figure 6As shown in the figure, a bottom buffer foam void structure 403 is provided in the middle of the bottom buffer foam 4, which can prevent the refrigerator from deforming when the force is transmitted from the bottom to the bottom surface of the refrigerator when it is impacted by a fall. At the same time, the bottom buffer foam 4 is composed of a bottom buffer foam A 401 and a bottom buffer foam B 402 that are snap-fitted together. The bottom buffer foam A 401 is provided with a bottom buffer foam splicing ramp 4011, and a bottom buffer foam fixing groove 4012 is opened on the bottom buffer foam splicing ramp 4011. The bottom buffer foam B 402 is provided with a ramp complementary to the bottom buffer foam splicing ramp 4011, and a bottom buffer foam fixing protrusion 4021 matching the bottom buffer foam fixing groove 4012 is provided on the ramp.

[0039] The sum of the width of the upper surface of the bottom buffer foam A 401 and the length of the bottom buffer foam splicing ramp 4011 is equal to the width of the refrigerator. So that when unpacking the refrigerator, instead of lifting the whole refrigerator and moving it away from the bottom buffer foam 4 to an open space, the refrigerator can be tilted towards the bottom buffer foam A 401 first. At this time, the bottom buffer foam B 402 can be pulled out from the side. Then, the suspended side of the refrigerator is lowered to the ground along the bottom buffer foam splicing ramp 4011. Next, the refrigerator is tilted towards the ground, and at this time, the bottom buffer foam A 401 can be pulled out from the other side. Finally, the whole refrigerator is lowered to the ground.

[0040] As Figure 7 、 8 As shown in the figure, the paper surrounding frame 5 is formed by cutting, scoring, and folding a flat corrugated cardboard. After scoring, 5 end faces are formed. The end faces at both ends are the short end face 501 and the long end face 502 of the paper surrounding frame. A number of paper surrounding frame buckle slots 503 are respectively opened on the short end face 501 and the long end face 502 of the paper surrounding frame. After folding, the paper surrounding frame buckle slots 503 opened on the short end face 501 and the long end face 502 of the paper surrounding frame just coincide, so as to facilitate the placement of the paper surrounding frame buckle 6 to fix the paper surrounding frame 5.

[0041] As Figure 9 、 10, as shown in Fig. 11, the paper enclosure buckle 6 includes a bayonet ring 605 adapted to the paper enclosure buckle groove 503. The bayonet ring 605 is a bottomless box-shaped structure composed of a rectangular ring thin sheet 6051 and a rectangular enclosure 6052 which are integrally arranged. At the same time, two sides of the rectangular ring thin sheet 6051 extend outwards and can cover the long end face 502 of the paper enclosure. Below the rectangular enclosure 6052, there are provided a small buckle piece 601 with a buckle groove 603 and a large buckle piece 602 with a buckle tooth 604 which can both rotate around the edge of the rectangular enclosure 6052. The buckle groove 603 is adapted to the buckle tooth 604, and the buckle groove 603 and the buckle tooth 604 in the buckled state are located inside the rectangular enclosure 6052. The small buckle piece 601 and the large buckle piece 602 rotate around the edge of the rectangular enclosure 6052, so that the buckle groove 603 and the buckle tooth 604 are unlocked or buckled, thereby controlling the opening and closing state of the paper enclosure buckle 6.

[0042] During use, first, rotate the small buckle piece 601 and the large buckle piece 602 upwards by a certain angle so that they can pass through the short end face 501 and the long end face 502 of the paper enclosure, and the paper enclosure buckle 6 is embedded in the paper enclosure buckle groove 503; then press down the small buckle piece 601 so that the upper surface of the small buckle piece 601 fits with the inner surface of the short end face 501 of the paper enclosure; then press down the buckle tooth 604 to engage it in the buckle groove 603 so that the upper surface of the large buckle piece 602 fits with the inner surface of the short end face 501 of the paper enclosure, then the paper enclosure buckle 6 is in the buckled state. In the buckled state, the short end face 501 and the long end face 502 of the paper enclosure are locked between the large and small buckle pieces and the rectangular ring thin sheet 6051. By locking the short end face 501 and the long end face 502 of the paper enclosure with the paper enclosure buckle 6, the paper enclosure 5 is fixed and not easily scattered. In the case of limited space, by unlocking the paper enclosure buckle 6, the internal product can be taken out without damaging the paper enclosure, and the paper enclosure 5 can be reused. During storage, the paper enclosure 5 can be fully unfolded into a flat cardboard, thereby reducing the storage area.

[0043] As Figure 12 shown, the L-shaped carton edge protector 9 is provided with a carton edge protector bundling belt hole 902, and carton edge protector reinforcing ribs 901 are arranged on both sides of the carton edge protector bundling belt hole 902, which play a role in strengthening and preventing deformation. Similarly, as Figure 13As shown in the figure, a number of carton corner protector strapping holes 1002 are provided on the U-shaped carton corner protector 10, and carton corner protector reinforcing ribs 1001 are arranged on both sides of each carton corner protector strapping hole 1002. When strapping the carton top cover 7 and the paper surrounding frame 5, the strapping bands 8 respectively pass through the carton corner protector strapping holes 1002 and the carton edge protector strapping holes 902, and pass through the corners of the L-shaped carton edge protector 9 and the U-shaped carton corner protector 10, so that the tightening force of the strapping bands 8 is more applied to the L-shaped carton edge protector 9 and the U-shaped carton corner protector 10, avoiding stress concentration on the paper surrounding frame 5; at the same time, it can prevent the strapping bands 8 from exerting pressure on the paper surrounding frame 5, enhancing the protection of the corner protectors of the paper surrounding frame 5 and the bottom buffer foam 4. The L-shaped carton edge protector 9 and the U-shaped carton corner protector 10 improve the impact resistance of the four corners at the bottom of the package, effectively preventing the refrigerator package from being damaged by bumps and impacts during loading, unloading and handling.
