Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] This invention provides a lightweight corrugated cardboard cushioning pad, such as... Figure 1-8 As shown, the cup includes an opening 1. Multiple inwardly inclined portions 2 are fixedly connected to the bottom of the opening 1. A side plate 3 is fixedly connected to the bottom of each inclined portion 2, and an outwardly protruding portion 4 is fixedly connected between adjacent side plate portions 3. A first receiving space for placing the mouth of the coffee cup is formed between the inclined portion 2 and the opening 1. A second receiving space for placing the body of the coffee cup is formed between the side plate portion 3 and the outwardly protruding portion 4. A first concave strip 5 and a second concave strip 6 are respectively provided on the upper and lower sides of the outwardly protruding portion 4. The two ends of the first concave strip 5 are fixedly connected to the top of the side plate portion 3. When the first concave strip 5 is folded downwards, it causes the bottom of the inclined portion 2 to retract inwards. The two ends of the second concave strip 6 are fixedly connected to the bottom of the side plate portion 3. The second concave strip 6 is located below the bottom of the coffee cup, and multiple second concave strips 6 form a buffer space below the coffee cup.

[0029] When in use, press the bottom of the coffee cup into the opening 1. As the coffee cup enters, it will first be blocked by the first concave strip 5. Continue pressing down, and the coffee cup will cause the first concave strip 5 to fold downwards. When the first concave strip 5 folds downwards, it will cause the bottom of the inclined part 2 to contract inwards, so that the bottom of the inclined part 2 is completely in contact with the coffee cup. The fit is good. Continue pressing down until the bottom of the coffee cup contacts the second concave strip 6. Multiple second concave strips 6 form a buffer space under the coffee cup. Utilizing the elasticity of the cardboard, the second concave strips 6 can effectively absorb vibration and impact during transportation, thus effectively protecting the coffee cup with good protective performance.

[0030] The opening 1 is set as a square, and the inclined part 2 is set as a trapezoid.

[0031] The opening 1, the inclined part 2, the side plate part 3, the outward protrusion 4, the first concave strip 5, and the second concave strip 6 are integrally formed.

[0032] It also includes a fixing component 7 for preventing excessive spacing between the second concave strips 6, which fixes the inner end of the second concave strip 6 to the inside of the outer edge of the bottom of the coffee cup.

[0033] The fixing component 7 includes a first base 71, a first buffer pad 72, and a protrusion 73. The first base 71 is configured in a cross shape, and the first buffer pad 72 is fixedly connected to the top center of the first base 71. Each end of the first base 71 is fixedly connected to a protrusion 73, and the protrusion 73 fits against the end of the second concave strip 6.

[0034] Because some coffee cups are designed in a frustum shape, wider at the top and narrower at the bottom, the diameter of the bottom of the cup is relatively small, while the diameter of the top of the cup is relatively large. In this case, the second concave strip 6 may only have its end in contact with the bottom of the cup. During transportation, the second concave strip 6 may undergo elastic deformation, causing the bottom of the cup to pass through the gaps between the four second concave strips 6. At this point, the buffer space formed by the second concave strip 6 will lose its function, causing the bottom of the cup to directly collide with the bottom. By setting up the fixing component 7, the end position of the second concave strip 6 can be effectively fixed, ensuring that the second concave strips 6 do not separate too much, so that the bottom of the cup will not pass through the gaps between the second concave strips 6. Therefore, it is suitable for some coffee cups with a small bottom diameter and a large body diameter.

[0035] With the first buffer pad 72 and the second buffer pad 75 in place, when the second concave strip 6 is subjected to large bumps and deforms too much and loses its buffering ability, the first buffer pad 72 and the second buffer pad 75 can play a buffering role, which is suitable for some bumpy road conditions.

[0036] The fixing component 7 includes a second base 74, a second buffer pad 75, a protruding edge 76, and a folding strip 78. The second buffer pad 75 is fixedly connected to the top center of the second base 74. The protruding edge 76 is fixedly connected to the outer edge of the second base 74, and a slot 77 matching the second concave strip 6 is provided on the protruding edge 76. A rectangular groove 79 is provided on the second base 74. The folding strip 78 is disposed in the rectangular groove 79 and one end is connected to the second base 74. The folding strip 78 is folded three times, and the end of the folding strip 78 forms a downward protruding limiting part, which fits against the end of the second concave strip 6.

[0037] By setting the protruding edge 76 and the slot 77, the second concave strip 6 can be initially fixed and positioned. At this time, the limiting part at the end of the folding strip 78 can be easily flipped to the end of the second concave strip 6. By setting the folding strip 78, during transportation, the bottom of the coffee cup will press on the folding strip 78, pressing the folding strip 78 above the second concave strip 6, so that the limiting part at the end of the folding strip 78 further fixes the second concave strip 6.

[0038] The second base 74 is designed as a regular octagon.

[0039] The first buffer pad 72 and the second buffer pad 75 are the same size and shape, and both the first buffer pad 72 and the second buffer pad 75 are made of buffer material.

[0040] Working principle: When in use, press the bottom of the coffee cup into the opening 1. When the coffee cup enters, it will first be blocked by the first concave strip 5. If you continue to press down, the coffee cup will cause the first concave strip 5 to fold downward. When the first concave strip 5 folds downward, it will cause the bottom of the inclined part 2 to fold inward, so that the bottom of the inclined part 2 is completely in contact with the coffee cup. The fit is good. Continue to press down until the bottom of the coffee cup contacts the second concave strip 6. Multiple second concave strips 6 form a buffer space under the coffee cup. Utilizing the elasticity of the cardboard, the second concave strips 6 can effectively absorb the shock during transportation, thus effectively protecting the coffee cup with good protective performance.

[0041] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
