[0034] To solve the above technical problems, the following embodiments are adopted in this application for processing.

[0035] Embodiment 1

[0036] As Figure 1 and Figure 2 shown, this application provides a packaging foam structure, which includes a foam packaging surface assembly 10; wherein, the foam packaging surface assembly 10 includes: an inner pad 110, which is arranged to fit the circumferential side surface of the product 40 on its inner side; an outer pad 120, which is arranged on the outer side of the inner pad 110 and forms an accommodation space 140 between it and the inner pad 110; a buffer padding 130, which is arranged in the accommodation space 140 and applies a force towards the cardboard box 30 to the outer pad 120, so that the outer side of the outer pad 120 fits the inner side surface of the cardboard box 30.

[0037] Specifically, this application selects an inner pad 110 corresponding to the shape of the product 40, and uses the inner side of the inner pad 110 to cooperate with the product 40 to wrap the product 40. Subsequently, the outer pad 120 and the buffer padding 130 are assembled on the outer side of the inner pad 110 to form a packaging body. Among them, the buffer padding 130 is arranged in the accommodation space 140 formed between the outer pad 120 and the inner pad 110, and the buffer padding 130 is used to prepare for buffering external impact forces in the future. Finally, the above packaging body is slightly compressed and then put into the cardboard box 30. At this time, since the volume of the buffer padding 130 can change according to the external force and store the corresponding elastic potential energy, when the above packaging body is put into the cardboard box 30, the elastic potential energy of the buffer padding 130 is released, and the outer pad 120 fits the inner side surface of the cardboard box 30 under the action of the force towards the cardboard box 30 from the buffer padding 130, thereby reducing the gap between the cardboard box 30 and the packaging body and preventing the packaging body from shaking inside the cardboard box 30, and further protecting the product 40.

[0038] Moreover, when the cardboard box 30 containing the above-mentioned package is subjected to an external impact force during transportation, the external impact force is transmitted to the buffer cushioning material 130 through the outer cushion 120, then to the inner cushion 110 and then to the product 40. By using the above method, the external impact force can be gradually weakened, and based on the fact that the buffer cushioning material 130 can store corresponding elastic potential energy according to the external force, the package of the present application can effectively offset the external impact force and ensure that the product 40 is not affected by the external impact force.

[0039] When the user performs an unpacking operation on the cardboard box 30 containing the above-mentioned package, the user can extract the buffer cushioning material 130 in the accommodation space 140. When the buffer cushioning material 130 is completely extracted or partially extracted, there will be a gap between the inner cushion 110 and the outer cushion 120. At this time, the outer cushion 120 will lose the force towards the cardboard box 30 from the buffer cushioning material 130, and the outer cushion 120 will not be arranged in contact with the inner side surface of the cardboard box 30, so that a gap is also formed between the outer cushion 120 and the cardboard box 30. At this time, the user can easily extract the outer cushion 120 by using the gap, and then take out the cardboard box 30 together with the product 40 by grasping the inner cushion 110, solving the technical problem of difficult extraction of the foam packaging box and the product 40 during unpacking. The user can also reach in through the gap between the outer cushion 120 and the cardboard box 30 and take out the outer cushion 120, the inner cushion 110 and the product 40 together from the cardboard box 30.

[0040] It should be noted that the foam packaging surface assembly 10 described in the present application only needs to act on the peripheral side surface of the product 40, and for the top surface and the bottom surface of the product 40, the foam packaging surface assembly 10 of the present application can continue to be selected, or other packaging pads can be used, and the present application does not limit this.

[0041] In this embodiment, the inner cushion 110 and the outer cushion 120 can be foam plates of the same size in the shape of a rectangle or a square. Among them, corresponding accommodation grooves and / or limiting convex parts will be provided on the inner side of the inner cushion 110 according to the shape of the product 40.

[0042] In one embodiment, the buffer cushioning material 130 includes bubble wrap and / or bubble cotton. When the bubble wrap (also known as bubble paper or bubble film) is used as the buffer cushioning material 130, the bubble surface of the bubble wrap contacts the inner side of the outer cushion 120 and forms a dense shock-absorbing layer with the outer cushion 120.

[0043] Compared with the prior art, in the present application, by filling the buffer padding material 130 in the accommodation space 140 between the outer pad 120 and the inner pad 110, the inner side of the inner pad 110 is arranged to fit the circumferential side surface of the product 40 and the outer pad 120 is arranged to fit the inner side surface of the cardboard box 30, ensuring the protection of the product 40 in the present application; when opening the box in the present application, after extracting the buffer padding material 130, there is a gap between the inner pad 110 and the outer pad 120, and the user can easily extract the outer pad 120 by using the gap, and then by grasping the inner pad 110, the product 40 can be taken out of the cardboard box 30 together, solving the technical problem of difficult extraction of the foam packaging box and the product 40 when opening the box.

[0044] Embodiment 2

[0045] As Figure 3 and Figure 4 shown, this embodiment is basically the same as Embodiment 1, the difference is that, in this embodiment, a plurality of abutting parts 111 are arranged on the outer side of the inner pad 110, and the plurality of abutting parts 111 are in contact with the circumferential side of the outer pad 120; in the width direction, a grasping space 160 is arranged between the abutting part 111 and the inner side surface of the cardboard box 30. In the present application, by arranging the abutting parts 111 to limit the circumferential direction of the outer pad 120, it is ensured that the outer pad 120 can only move in the direction towards the cardboard box 30 under the action of the buffer padding material 130. Moreover, a grasping space is arranged between the abutting part 111 and the inner side surface of the cardboard box 30, which is convenient for the user to reach into the grasping space with the hand during the box-opening operation and grasp the inner pad 110 by grasping the abutting part 111 located above the inner pad 110, and during the process of grasping the inner pad 110 and extracting it from the cardboard box 30, the outer pad 120 will be lifted by the abutting part 111 under the inner pad 110 and taken out of the cardboard box 30 together.

[0046] Further, a grasping groove is arranged on the side of the abutting part 111 facing the cardboard box 30 in the width direction. When the user reaches into the grasping space with the hand during the box-opening operation and inserts the fingers into the grasping groove, grasps the abutting part 111 located above the inner pad 110 to grasp the inner pad 110, and during the process of grasping the inner pad 110 and extracting it from the cardboard box 30, the outer pad 120 will be lifted by the abutting part 111 under the inner pad 110 and taken out of the cardboard box 30 together.

[0047] Further, extraction spaces 150 are provided between opposite ends of the abutting portion 111 in the length direction and the inner side surface of the cardboard box 30, and the extraction spaces 150 communicate with the accommodation space 140. In this application, by providing the extraction spaces 150, the extraction spaces 150 are used to extract the cushioning material 130 in the accommodation space 140. Specifically, the extraction spaces 150 are located above the accommodation space 140. It should be noted that the up, down, left, and right directions mentioned in this application are defined with the opening of the cardboard box 30 as the upper side.

[0048] Further, a plurality of the abutting portions 111 are respectively arranged at the middle positions on the peripheral side of the inner pad 110. By arranging them at the middle positions, on a certain side direction of the peripheral side, only one abutting portion 111 is needed to support the outer pad 120 and grip the inner pad 110.

[0049] Since the inner pad 110 of this application is provided with the abutting portions 111, and the abutting portions 111 are in contact with the outer pad 120, that is, the size of the outer pad 120 is smaller than that of the inner pad 110, this will cause vacancies in the positions of the extraction spaces 150. This will result in the extraction spaces 150 being prone to collapse after being impacted by an external impact force when the packaging body is loaded into the cardboard box 30. To solve the above problems, further, the foam packaging structure further includes a foam packaging corner assembly 20, which is arranged at the extraction spaces 150, and the foam packaging corner assembly 20 is detachably connected to the foam packaging surface assembly 10. In this embodiment, by providing the foam packaging corner assembly 20 to fill the vacancies in the extraction spaces 150, and the foam packaging corner assembly 20 is detachably connected to the foam packaging surface assembly 10, so that when the user opens the box, the extraction spaces 150 can be exposed by detaching the foam packaging corner assembly 20, so as to further extract the cushioning material 130 in the accommodation space 140.

[0050] Further, the foam packaging corner assembly 20 has an adhesive surface, and the foam packaging corner assembly 20 is fixedly adhered to the foam packaging surface assembly 10 through the adhesive surface. In this embodiment, the foam packaging corner assembly 20 is adhered to the foam packaging surface assembly 10 (the inner pad 110 and the outer pad 120) by adhesion, which is convenient for detaching the foam corner assembly. It should be noted that the adhesive surface can use adhesive tapes with ordinary adhesive ability such as double-sided tape, so that the user can easily take out the foam packaging corner assembly 20.

[0051] Furthermore, both the inner side surface (i.e., the side facing the inner pad 110) and the outer side surface (i.e., the side facing the outer pad 120) of the cushioning material 130 are provided with sticking points, and the sticking points are arranged at diagonal positions on the same surface of the cushioning material 130; the cushioning material 130 is adhesively connected to the outer pad 120 and the inner pad 110 through the sticking points. In the present application, the connection between the cushioning material 130 and the inner pad 110 and the outer pad 120 is achieved through the sticking points, and the sticking points on the same surface are arranged diagonally, which is convenient for the user to extract the cushioning material 130 by pulling out the un-stuck corner. It should be noted that the sticking points can use adhesive tapes with ordinary sticking ability such as double-sided tapes, so that the user can easily extract the cushioning material 130.

[0052] According to the disclosure and teachings of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
