DETAILED DESCRIPTION

[0038] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] As shown in FIGS. 1-6, the present application discloses a new type of environmentally friendly cushion packaging structure, comprising a base plate 1 and a telescopic cushion pad 2, the two ends of the same side of the base plate 1 are fixedly connected with the telescopic two ends of the cushion pad 2 to form an integrated structure, and the fixed connection here can be an adhesive connection, a clamping connection, a riveting connection and other commonly used packaging box fixed connection structures;

[0040] The cushion pad 2 is a honeycomb paper core formed by interlaced adhesion of a plurality of paper strips, and the inside thereof is spliced by a plurality of telescopic deformable through holes 21. By pulling the telescopic two ends of the cushion pad 2, the through holes 21 can be deformed and expanded, thereby realizing the telescopic effect of the cushion pad 2. At the same time, due to the setting of the honeycomb structure, the connecting boundaries of adjacent through holes 21 can form a good support and buffering effect on the two end faces of the cushion pad 2, and can effectively increase the buffering support force on the packaging object 4. The base plate 1 is provided with a plurality of fold lines 3, and the base plate 1 can be bent along the fold lines 3 to one side of the cushion pad 2 and cover the outer periphery of the cushion pad 2. The cushion pad 2 is passively bent and stretched to form a columnar wrapping state under the traction of the base plate 1, and the end face of the cushion pad 2 away from the base plate 1 is a cushioning surface 22. In the wrapping state, the cushioning surface 22 forms a packaging cavity 23 for accommodating the packaging object 4;

[0041] As shown in FIG. 1, the middle part of the base plate 1 is also provided with a middle fold line 31. Before use, the base plate 1 can realize a folded storage state under the folding action of the middle fold line 31. At this time, the cushion pad 2 is also in a folded and contracted storage state and is fixed at the end of the base plate 1 away from the middle fold line 31. That is, in the storage state, the packaging structure as a whole is flat, which is convenient for stacking and storing a plurality of packaging structures, thereby effectively saving storage space.

[0042] As shown in FIGS. 1-3, when in use, the base plate 1 only needs to be bent along the fold lines 3 to drive the cushion pad 2 to bend and stretch. At this time, the packaging object 4 is placed and abuts at the cushioning surface 22. Under the continuous bending and stretching action of the base plate 1 and the cushion pad 2, the cushioning surface 22 forms the packaging cavity 23 surrounding the packaging object 4, and the base plate 1 forms a box structure and wraps around the outer periphery of the cushion pad 2.

[0043] Through the integral linkage folding design of the substrate 1 and the buffer pad 2, the substrate 1 and the buffer pad 2 can be quickly switched between the storage state and the wrapping state freely, simply and conveniently, facilitating the quick wrapping of the package 4 by the consumer; at the same time, in the wrapping state, the substrate 1 forms a stable box structure, which can well support and protect the package 4 located in the box, and the buffer pad 2 arranged between the inner wall of the substrate 1 and the package 4 can better buffer and protect the package 4, further improving the wrapping stability and safety of the package 4;

[0044] Since the kraft paper is inexpensive and has good flexibility and tear resistance, the material of the buffer pad 2 is preferably kraft paper; at the same time, the material of the substrate 1 is preferably corrugated paperboard, so that the substrate 1 has sufficient packaging hardness, and the overall material of the packaging structure is more environmentally friendly and has lower cost.

[0045] Specifically, as shown in FIG. 3, the substrate 1 is provided with openings 5 at both ends along the extension direction of the folding line 3, the substrate 1 is provided with a sealing plate 51 for covering the openings 5, and the buffer pad 2 is provided with a support portion 24 integrally formed with the structure of the buffer pad 2 on the side close to the openings 5, the support portion 24 being arranged in abutment between the sealing plate 51 and the end portion of the package 4 in the wrapping state;

[0046] It should be noted that in the production process, the buffer pad 2 is obtained by stacking a plurality of paper sheets in sequence and bonding adjacent paper sheets, and the bonding portions between adjacent paper sheets are arranged in a staggered manner, so that the buffer pad 2 can form a honeycomb structure with a plurality of through holes 21 when stretched; after bonding, the buffer pad 2 with different thicknesses and shapes is cut according to the actual shape requirements of the package 4, and the cut buffer pad 2 includes a main body portion corresponding to the peripheral wall of the package 4 and a support portion 24 for abutting against the end portion of the package 4, so that the clever design structure of the buffer pad 2 and the support portion 24 can effectively improve the packaging efficiency and better fit the package 4 when the packaging structure is used by the consumer, further improving the safety, stability and convenience of the packaging.

[0047] In an embodiment, as shown in FIGS. 1-6, the substrate 1 comprises a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14, a fifth side plate 15, a sixth side plate 16 and a seventh side plate 17 connected in turn, the folding line 3 is arranged at each rotation connection, and the two ends of the buffer pad 2 are fixedly connected with the first side plate 11 and the seventh side plate 17 respectively; in the wrapped state, the two ends of the buffer pad 2 are fixedly connected with the first side plate 11 and the seventh side plate 17 respectively, and the other end faces of the first side plate 11 and the seventh side plate 17 are in close abutment with each other;

[0048] Specifically, as shown in FIGS. 1 and 5, in the present embodiment, the support part 24 is arranged along the direction perpendicular to the extension direction of the folding line 3 or the length direction of the buffer pad 2, so that the buffer pad 2 as a whole has a "C" shape structure, and a notch 6 is arranged in the "C" shape structure, the curve profile of the notch 6 matches the curve profile of the section surface of the outer surface of the packaging object 4, that is, the end edges of the first side plate 11 and the seventh side plate 17 and the side edge of the buffer pad 2 are provided with corresponding notches 6, and the shapes of the first side plate 11 and the seventh side plate 17 are adapted to the stretchable end face shape of the buffer pad 2;

[0049] Through the arrangement of the notch 6, the inner peripheral wall structure of the packaging cavity 23 can highly match the outer peripheral wall structure of the packaging object 4 in the wrapped state of the substrate 1 and the buffer pad 2, further increasing the contact area and adaptability of the buffer pad 2 and the outer peripheral wall of the packaging object 4, and providing more comprehensive buffering support for the packaging object 4, thereby effectively improving the wrapping buffering force and fixing effect of the packaging object 4; in the present embodiment, the packaging object 4 can preferably be a bottle type fragile product, such as a wine product, a glass crystal product, etc.;

[0050] Further, the notch 6 is provided with a rotation axis P, when the substrate 1 drives the buffer pad 2 to bend and stretch, the buffer pad 2 rotates and stretches around the rotation axis P and forms a wrapped state;

[0051] Further, as shown in FIG. 6, one end of the sealing plate 51 is rotationally connected with the fourth side plate 14, and two support plates 52 of right triangle structure are further arranged at the opening 5, the two support plates 52 are symmetrically arranged at the opening 5, two right angle edges of one support plate 52 are rotationally connected with the sealing plate 51 and the third side plate 13 respectively, and two right angle edges of the other support plate 52 are rotationally connected with the sealing plate 51 and the fifth side plate 15 respectively; wherein, the support plate 52 is further provided with a crease 7 for bending and folding the support plate 52 towards the opening 5;

[0052] It should be noted that a plurality of sealing plates 51 or a plurality of support plates 52 of non-right triangle structure can also be arranged at the opening 5, and the opening 5 is covered by the mutual stacking of the sealing plates 51 and / or the support plates 52. In the embodiment, the right triangle structure of the support plate 52 is preferably adopted. Compared with the stacking mode of the plurality of sealing plates 51 or the plurality of support plates 52, the two sides of the right triangle structure of the support plate 52 are integrally connected with the base plate 1 and the sealing plate 51 respectively, and the folding design of the crease 7 is adopted, so that when the consumer covers the opening 5, the sealing plate 51 only needs to be pushed towards the opening 5. Under the driving of the sealing plate 51, the two support plates 52 are automatically bent and folded along the crease 7 and stored between the buffer pad 2 and the sealing plate 51, so that the packaging is more convenient and fast. At the same time, the support plate 52 is inwardly folded to form a double-layer structure, so that the base plate 1 can provide more firm support to the support part 24, thereby improving the wrapping safety of the packaging 4.

[0053] Preferably, the end of the sealing plate 51 away from the fourth side plate 14 can be connected with the opening 5 in a commonly used packaging box connection mode such as adhesive connection, clamping connection, riveting connection, etc. In the embodiment, the end of the sealing plate 51 and the opening 5 are preferably connected in a clamping connection, that is, the sealing plate 51 is rotatably connected with a lock tongue 511. The lock tongue 511 can also adopt a double-layer structure, and the lock tongue 511 is provided with a first clamping groove 512. The first side plate 11 and the seventh side plate 17 are both provided with a second clamping groove 18 corresponding to the first clamping groove 512. In use, the sealing plate 51 covers the opening 5 in the direction of the opening 5, the lock tongue 511 is inserted into the inside enclosed by the base plate 1, and the first clamping groove 512 and the second clamping groove 18 are mutually embedded and clamped and fixed, so as to realize the glue-free, fast and convenient covering of the opening 5 by the sealing plate 51. The design is ingenious and environmentally friendly.

[0054] In an embodiment, as shown in FIGS. 7-11, the base plate 1 includes a first side plate 11, a second side plate 12, a third side plate 13 and a fourth side plate 14 connected in sequence, and the folding line 3 is arranged at each rotationally connected position. The two ends of the buffer pad 2 are connected with the first side plate 11 and the fourth side plate 14 respectively. The first side plate 11 or the fourth side plate 14 is provided with a fixed plate 19, and the fixed plate 19 is provided with a fixed part 191.

[0055] In the wrapped state, the free end edges of the first side plate 11 and the fourth side plate 14 abut each other, the cushion 2 is located inside the base plate 1 to form a wrapped state, and the fixing portion 191 of the fixing plate 19 is fixedly connected with the outer peripheral wall of the fourth side plate 14 or the first side plate 11, so that the base plate 1 maintains a box structure. The fixed connection here can be adhesive connection, clamping connection, riveting connection, etc. In this embodiment, the fixing portion 191 is provided with adhesive and is bonded with the outer peripheral wall of the fourth side plate 14 or the first side plate 11.

[0056] Specifically, the fixing plate 19 is provided with a tear strip 8 extending along the extension direction of the fold line 3, and the tear strip 8 is located between the rotation connection between the fixing plate 19 and the base plate 1 and the fixing portion 191.

[0057] Taking the rotation connection between the fixing plate 19 and the first side plate 11 as an example, in use, the consumer bonds the fixing portion 191 on the fixing plate 19 to the fourth side plate 14, so that the base plate 1 and the cushion 2 form a wrapped state, facilitating the transportation and protection of the packaged object 4. After delivery is completed, when the packaged object 4 needs to be taken out, only the tear strip 8 needs to be torn to separate the fixing portion 191 and the rotation connection between the fixing plate 19 and the base plate 1, so that the wrapped state is released and the packaged object 4 can be taken out. Therefore, through the design of the fixing plate 19 and the tear strip 8, the packaging of the packaged object 4 and the convenience of taking out after packaging are further improved.

[0058] Further, as shown in FIGS. 10-11, in this embodiment, the support portion 24 can also be arranged along the extension direction of the fold line 3, that is, the cushion 2 has a long strip structure as a whole. Therefore, in the wrapped state, the cushion 2 has a cylindrical structure and wraps and buffers the packaged object 4, and because the extension direction of the support portion 24 is consistent with the extension direction of the fold line 3, the support portion 24 extends outward through the opening 5 at this time, but under the limiting action of the sealing plate 51, the support portion 24 is abutted and bent by the sealing plate 51 and is bent towards the end portion of the packaged object 4, and finally abuts between the packaged object 4 and the sealing plate 51, and provides effective support and fixation for the end portion of the packaged object 4.

[0059] The opening 5 sealing structure in this embodiment is the same as above, and will not be described again here.

[0060] In an embodiment, as shown in FIGS. 12-15, due to the problem of excessive volume of part of the packaging 4 (such as the display screen), while part of the surface of the packaging 4 (such as the back shell) is solid and can not be protected by the buffer, for this kind of packaging 4, a semi-enclosed packaging structure can also be used for packaging, that is, in this embodiment, the substrate 1 includes a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14 and a fifth side plate 15 connected in turn, and the folding line 3 is arranged at the rotating connection, and the two ends of the buffer pad 2 are fixedly connected with the first side plate 11 and the fifth side plate 15 respectively.

[0061] As shown in FIG. 13, in the wrapped state, the first side plate 11 and the fifth side plate 15 are fixed symmetrically on the back of the packaging 4, the second side plate 12 and the fourth side plate 14 are also symmetrically arranged on the two side walls of the packaging 4, and the third side plate 13 with the largest area corresponds to the front part (such as the screen part of the display screen) of the packaging 4 which needs to be protected, at this time, the packaging 4 is placed in the packaging cavity 23, and the back of the packaging 4, the two side walls and the front are also tightly wrapped by the buffer pad 2 after stretching, and through the wrapping arrangement of the buffer pad 2 and the substrate 1, the double buffer fixed protection of the important parts of the packaging 4 is effectively realized.

[0062] Further, as shown in FIG. 14, the buffer pad 2 is also provided with a support part 24 extending perpendicular to the folding line 3, which surrounds the edge of the packaging 4 close to the opening 5 when wrapped, so as to realize the position clamping and fixing of the packaging 4, since the edge of the packaging 4 (such as the display screen) is a right angle structure, the support part 24 which is also a right angle structure can better fit the edge of the packaging 4, thereby improving the fixing stability of the packaging 4.

[0063] Further, as shown in FIGS. 14-15, at the opening 5, the first side plate 11 and the fifth side plate 15 are both rotatably connected with an enclosing plate 51, the other end of the enclosing plate 51 is provided with a locking lug 513, and the third side plate 13 is provided with a locking groove 131 corresponding to the locking lug 513; at the same time, the second side plate 12, the third side plate 13 and the fourth side plate 14 are all provided with the support plate 52.

[0064] When the substrate 1 and the cushion 2 are in the folded state, the support plates 52 on the third side plate 13 are folded to wrap the support part 24 of the cushion 2, and then other support plates 52 are stacked in turn to cover the opening 5 and abut against the end of the support part 24, and then a part of the cover plate 51 is bent to cover the outermost support plate 52, and then another part of the cover plate 51 is bent to abut against the back of the third side plate 13, and finally the locking lug 513 is clamped into the locking groove 131 of the third side plate 13 to fix the box structure of the substrate 1.

[0065] It should be noted that the cover plate 51 can also be fixedly connected to the outermost support plate 52 or the back of the third side plate 13 by bonding or riveting.

[0066] The working principle of the present application will be described in detail as follows.

[0067] When in use, the substrate 1 and the cushion 2 in the folded state are unfolded, and then the packaging material 4 is pressed against the cushion surface 22 of the cushion 2, at this time the substrate 1 is folded along the folding line 3 and around the packaging cavity 23 or the packaging material 4 under the pressing action, while driving the passive stretching of the cushion 2 and forming a wrapped state around the packaging cavity 23 to fix the packaging material 4; then the support plate 52 and the cover plate 51 are used to cover the opening 5 by bonding, clamping or riveting, so as to realize the quick packaging of the packaging material 4.

[0068] The innovation of the present application is that the integrated linkage folding design of the substrate and the stretchable cushion enables the wrapping and filling of the cushion to be completed simultaneously when the substrate is used to wrap the packaging material in a box shape, effectively improving the packaging efficiency and convenience of the packaging material; at the same time, the packaging structure uses degradable and environmentally friendly materials, which not only has lower manufacturing and using costs, but also is green and environmentally friendly.

[0069] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that can be understood by those skilled in the art.

[0070] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the patent document.
