The utility model discloses die-cutting district 12 behind well cross cutting indicates to cut out multirow cutting incision 122 through the mode of cross cutting on the paper material, and two adjacent rows of cutting incisions 122 are crisscross the setting each other, and after die-cutting district 12 is exerting external force, cutting incision 122 is stretched to three-dimensional shape, becomes three-dimensional grid structure. Wherein the cutting edge 122 is generally in the shape of a solid hexagon or a solid square after being stretched. The die cut area 12 is now increased in length while expanding in the thickness direction to form cushioning layer 14, thereby providing cushioning protection.

One specific configuration of the die cut area 12 includes: a plurality of cutting lines 121 arranged in a row, each cutting line 121 comprises a plurality of cutting openings 122 distributed at intervals, and the cutting openings 122 on two adjacent cutting lines 121 are formed in a staggered manner; the length and the cutting interval of the cutting slits 122 on each of the cutting lines 121 are the same. The die-cut area 12 has a three-dimensional hexagonal structure of the slits 122 after being stretched.

In the present embodiment, the thickness of the cushion pad 100 is the paper thickness when it is not deployed, and at this time, it can be transported to the overseas market by means of freight, which can save transportation cost; when the cushion pad 100 is stretched by a hand or a stretching device to expand the die-cut region 12 when it is used by a customer, the expanded cushion pad 100 is used as a cushion material.

Referring to fig. 3, the pad unit 10 has a plurality of pad units 10, and the plurality of pad units 10 are connected end to end. The cushion units 10 are formed by connecting a plurality of cushion units 10, and the cushion pad 100 is in a strip-shaped structure, so that strip-shaped stretching is facilitated to form the cushion layer 14, and when the cushion unit is wrapped on the outer side of an article, the cushion unit can be wound on the outer side of the article in multiple layers, and the cushion effect is further enhanced.

Referring to fig. 4 to 6, the present invention further manufactures the packing bag 200 by the cushion pad 100, and the thickness of the manufactured packing bag 200 is thinner before use, so that transportation cost can be effectively saved during transportation. The packaging structure with the buffer effect is changed into a packaging structure with the increased thickness after being unfolded by external force after being transported. In one preferred unfolding method, when an article is placed in the packaging bag 200, the cushion unit 10 is unfolded inside the packaging bag 200 to form the cushion layer 14 due to the gravity of the article or the pushing force during the placing, so as to achieve a cushion effect.

Specifically, the packing bag 200 includes an outer bag body and a cushion unit 10. The pad unit 10 is arranged in the outer bag body along the length direction, and two sides of the pad unit 10 in the width direction are not connected with the outer bag body, so that the die cutting area 12 can be conveniently unfolded; when an object is placed in the packing bag 200, the placing direction is the same as the length direction of the cushion unit 10, and the cushion unit 10 is unfolded in the placing direction and expanded in the thickness direction of the cushion unit 10, thereby playing a role of cushioning protection.

In the present embodiment, both ends of the pad unit 10 in the longitudinal direction are respectively disposed near the inner wall of the opening of the outer bag 20, and the center position of the pad unit 10 is suspended in the outer bag 20; after the pad unit 10 is unfolded along the putting direction, the center position of the pad unit 10 is moved to the bottom of the inner bag body, so that the buffer layer 14 can cover the whole side surface of the outer bag body 20, and the buffer effect of the protection bag is ensured.

Referring to fig. 7 and 8, in another embodiment of the present invention, each cushion unit 10 includes two die-cutting areas 12, and the two die-cutting areas 12 are respectively located at both sides of the transfer area 13. When the cushion unit 10 needs to be unfolded, one die-cutting area 12 is stretched by an external force, the stretching force is uniformly transmitted to the other die-cutting area 12 by the one die-cutting area 12 through the transmission area 13, so that the other die-cutting area 12 is unfolded, and the transmission area 13 can effectively prevent stretching distortion caused by non-uniform stretching force when the other die-cutting area 12 is unfolded, for example, a part of the area is unfolded to form a three-dimensional net structure, and the other part cannot be unfolded; in addition, two die-cut areas 12 have higher buffer utilization rate after being unfolded compared with the structure of one die-cut area 12, and the buffer layer 14 has larger wrapping range and better buffer effect when being wrapped or used as a filling material.

Referring to fig. 9, a plurality of pad units 10 having two die-cut areas 12 are connected end-to-end with each other to form a cushioning pad 100. Such a cushion pad 100, when wrapped around the surface of an article after stretching, further enhances the cushioning effect compared to a cushion pad 100 having only one die-cut area 12.

Referring to fig. 10 and 11, a packing bag 200 is also manufactured by using the packing unit 10 of the present embodiment, and specifically, the packing bag 200 includes an outer bag body 20 and a packing unit 10 having two die-cut regions 12. When the packing bag 200 is put in an object, the putting direction is consistent with the length direction of the cushion unit 10, the two die-cut regions 12 in the cushion unit 10 are unfolded along the putting direction, two buffer layers 14 are formed on the two side surfaces of the packing bag 200, and the two buffer layers 14 are expanded in the thickness direction of the cushion unit 10, thereby playing a role of buffering protection. This configuration can overcome the destructive force from any direction on both sides of the packing bag 200.

Similarly, two ends of the pad unit 10 in the length direction are respectively arranged near the inner wall of the opening of the outer bag body 20, and the center position of the pad unit 10 is suspended in the outer bag body 20; after the pad unit 10 is unfolded along the putting direction, the central position of the pad unit 10 is moved to the bottom of the inner bag body, so that the buffer layer 14 can cover the whole side surface of the outer bag body 20, and the whole two side surfaces are both covered, thereby ensuring that the protection bag has better buffer effect.

Referring to fig. 12, in another embodiment of the present invention, the gasket unit 10 may include a plurality of third faces 11, and both ends of the plurality of third faces 11 are connected to each other, in which case the plurality of third faces 11 may have only one die-cutting area 12, or two die-cutting areas 12, or a combination of one die-cutting area 12 and the gasket unit 10 having two die-cutting areas 12. In the present embodiment, the plurality of die-cut regions 12 of the third face 11 form the buffer layer 14 having a three-dimensional net structure after stretching, that is, the plurality of buffer layers 14, and the plurality of buffer layers 14 have a better buffer effect after overlapping.

Referring to fig. 13 and 14, the packing bag 200 is manufactured by using the packing unit 10 having the plurality of third surfaces 11, and the packing bag 200 has a better cushioning effect than the packing bag 200 manufactured by using the packing unit 10 having only one third surface 11.

In a preferred embodiment of the present invention, the cushion unit 10 has a plurality of third surfaces 11, and the transmission areas 13 of the third surfaces 11 of two adjacent layers are staggered or not completely overlapped. At this time, after the two layers of die cutting areas 12 are unfolded, at least one buffer layer 14 is opposite to the other layer of the transmission area 13, the transmission area 13 is made of paper materials which are not subjected to die cutting, the transmission area 13 can be used as a supporting surface of the other layer of the buffer layer 14, the buffer layer 14 acts on the supporting surface when being stressed, and the buffer layer 14 can have better restoring force after the supporting surface reacts, so that a better buffer effect is shown.

The above embodiment of the present invention does not need to stretch the die-cutting area 12 into the three-dimensional net structure when manufacturing the pad unit 10, and can save the transportation cost. In addition, when the packing unit 10 is manufactured into the packing bag 200, the packing unit does not need to be fixed inside the packing bag 200 in a three-dimensional net structure mode, and only the plane paper materials are directly connected or attached, so that the transportation cost can be saved, and the manufacturing process is relatively simple.

Referring to fig. 15, the present invention also discloses another buffering cushion 300, the buffering cushion 300 is made of paper material, and the buffering cushion 300 includes a cushion unit 30. The cushion unit 30 comprises a first surface 31 and a second surface 32, the first surface 31 is provided with an extension zone 311, the extension zone 311 can be extended along the length direction of the first surface 31, and the length of the first surface 31 is increased after the extension zone 311 is extended. Two ends of the second surface 32 in the length direction are respectively fixed at two ends of the first surface 31, a die cutting area 320 is arranged on the second surface 32, and the length of the die cutting area 320 is increased along with the expansion area 311 being expanded; the die-cut area 320 is unfolded to form a buffer layer, which makes the second side 32 expand in the thickness direction to play a role of buffer protection; the die-cut area 320 is unfolded to form a three-dimensional grid structure.

The die cutting area 320 comprises a plurality of cutting lines 322 arranged in a row, each cutting line 322 comprises a plurality of cutting openings 323 distributed at intervals, and the cutting openings 323 on two adjacent cutting lines 322 are formed in a staggered mode; the cutting cuts 323 on each of the cutting lines 322 are the same in length and interval. The cutting line 322 and the cutting opening can form a hexagonal three-dimensional opening when the die-cutting area 320 is stretched, so that the die-cutting area 320 forms a buffer layer to play a role of buffer protection.

In this embodiment, the extension region 311 is a region that can be stretched, the extended length of the extension region 311 is the same as the stretched length of the die-cut region 320 on the second surface 32, and the extended die-cut region 320 also forms a buffer layer having a three-dimensional net structure, and can play a role in buffering. The cushion unit 30 can be wrapped around the outside of the article for protection.

Referring to fig. 16, in another embodiment of the present invention, there are two extension regions 311, and two extension regions 311 are respectively close to two ends of the first surface 31. At this time, when the first surface 31 receives external force for stretching, the two extending regions 311 are synchronously extended along with the second surface 32, compared with the embodiment with only one extending region 311, the stretching is smoother, the stretching length of the extending region 311 is longer, and the requirement of a larger stretching ratio of the second surface 32 can be met.

Referring to fig. 17, in the present embodiment, the cushion pad 300 may have a plurality of pad units 30, the pad units 30 are connected end to end, and the first surface 31 and the second surface 32 are fixed to each other at the end of the pad units 30. The cushion units 30 are in a strip-shaped structure, so that the cushion pad 300 connected with the cushion units 30 is beneficial to strip-shaped stretching to form a cushion layer, and can be wrapped in a multi-layer winding mode outside the article when being wrapped outside the article, so that the cushion effect is further enhanced.

Referring to fig. 18, in the present embodiment, the pad unit 30 may also include a plurality of second surfaces 32, the second surfaces 32 are connected to each other at two ends of the first surface 31, and the second surfaces 32 form a multi-layer buffer structure after being stretched, so as to have a better buffer effect. It is preferable that the plurality of cutting lines 322 on the plurality of second surfaces 32 are arranged in a staggered manner, so that after the plurality of second surfaces 32 are stretched, the formed three-dimensional net-shaped structure is also staggered, and at this time, the plurality of buffer layers act or are meshed with each other, so that a larger supporting force can be provided, and a better buffer effect can be ensured.

Referring to fig. 19 and 20, the extension region 311 is formed by the first panel 31 being folded or folded in the width direction, and the extension region 311 is extended by the same length as the first panel 31 and the second panel 32.

The folding and creasing are relatively simple to manufacture, and the manufacturing process of the first surface 31 can be reduced, so that the production efficiency of the cushion unit 30 is ensured, and the cost is reduced. Referring to fig. 21 to 24, the present invention also discloses a packing bag 400 manufactured by using the cushion unit 30 of the present embodiment. Specifically, the packing bag 400 includes an outer bag body 40 and a cushion unit 30. The pad unit 30 is arranged in the outer bag body 40 along the length direction, and two sides of the pad unit 30 in the width direction are not connected with the outer bag body 40; when the packing bag 400 is put in an object, the putting direction is consistent with the length direction of the cushion unit 30, and the cushion unit 30 is unfolded in the putting direction and expanded in the thickness direction of the cushion unit 30, thereby playing a role of buffering protection.

The width of the cushion unit 30 is smaller than the width of the packing bag 400; after the cushion unit 30 is unfolded, two sides of the width of the cushion unit 30 are abutted against two inner sides of the outer bag 40, so that a relatively closed space is formed between the outer bag 40 and the cushion unit 30.

The two ends of the gasket unit 30 in the length direction are respectively arranged near the inner wall of the opening of the outer bag body 40, and the center position of the gasket unit 30 is suspended in the outer bag body 40; after the cushion unit 30 is unfolded in the input direction, the center position of the cushion unit 30 is moved to the inner bag bottom.

When the packing bag 400 is put into an object, the putting direction is consistent with the length direction of the cushion unit 30, the die cutting area 320 on the second face 32 is unfolded along the putting direction, two buffer layers 321 are formed on the two side faces of the packing bag 400, and the two buffer layers 321 are expanded in the thickness direction of the cushion unit 30, so that the buffer protection effect is achieved. This configuration can overcome the destructive force from any direction on both sides of the packing bag 400.

Here, the shape of the cushion unit 30 in the packing bag 400 when it is not unfolded is shown in fig. 21, and the structure of the cushion unit 30 in the packing bag 400 when it is unfolded is shown in fig. 22. As can be seen from the figure, when the second surface 32 is unfolded, the extending regions 311 on the first surface 31 are also unfolded synchronously, so as to form a smoother inner wall structure, which is convenient for the object to be placed.

Referring to fig. 23 and 24, it is preferable that a distance between one of the extension regions 311 and one end of the first face 31 is different from a distance between the other of the extension regions 311 and the other end of the first face 31. At this time, when the first surface 31 is unfolded, the two extending areas 311 are dislocated with each other, so that the narrow space inside the packaging bag 400 can be ensured not to interfere with each other when being unfolded, the resistance of the extending areas 311 when being unfolded is reduced, the objects can be placed more conveniently, and the unfolding effectiveness is also ensured.

Wherein, the length that two extension district 311 expanded is the same, and when the article was put into, the same length of expansion can guarantee that the position of object and first face 31 contact does not take place the displacement, and it is more smooth and easy to put into the article, overcomes because the frictional force of object and first face 31 leads to putting into the object comparatively difficult, perhaps needs bigger thrust just to make second face 32 expand, and wherein bigger thrust has probably to lead to first face 31 damaged.

It is further preferable that the extension region 311 is formed by folding in the width direction on the first face 31; the two extending regions 311 have small folding widths, so that the extending regions 311 can be conveniently unfolded in a small space.

Wherein less folding width can guarantee that expansion in the narrow and small space is more smooth, and thrust is littleer.

Referring to fig. 25 and 26, in a preferred embodiment, the width of the second surface 32 is slightly smaller than the width of the first surface 31, and it can be seen from the figure that when the second surface 32 is completely unfolded, the second surface 32 acts on the outer bag 40 and the first surface 31, so that the outer bag 40 and the first surface 31 are in contact near the side edge of the object placing direction, that is, the two longitudinal side edges of the first surface 31 abut against the inner wall of the outer bag 40, and the two longitudinal ends of the second surface 32 are connected near the opening of the outer bag 40, so that the second surface 32 is located in the space enclosed by the first surface 31 and the outer bag 40, on one hand, the second surface 32 itself has the buffer layer 321 to play a buffer role, and on the other hand, a cavity with air is formed in the second surface 32, and when the outer bag 40 is subjected to an external force, the air in the cavity can also play a buffer role, so that the buffer role is further enhanced.

Referring to fig. 27 and 28, in an embodiment of the present invention, the pad unit 30 includes two layers of second surfaces 32, the two layers of second surfaces 32 are connected to each other at the end of the pad unit 30, and after the pad unit 30 is manufactured into the packing bag 400, a two-layer buffer layer 321 is formed on each side surface inside the packing bag 400, so that the buffer effect of the packing bag 400 can be improved.

Referring to fig. 29 and 30, the cushion unit 30 of the present invention has yet another embodiment.

Wherein the second side 32 comprises a first sub-side 33 and a second sub-side 34, the first sub-side 33 and the second sub-side 34 are die-cut areas 320, and the first sub-side 33 and the second sub-side 34 together form the second side 32; one end of the first sub-surface 33 is connected with one end of the first surface 31, and the other end of the first sub-surface 33 is connected with the central line of the first surface 31 in the length direction; the second sub-surface 34 is connected to the other end of the first surface 31, and the other end of the second sub-surface 34 is connected to a longitudinal center line of the first surface 31.

Referring to fig. 31 and 32, in the present embodiment, when the packing bag 400 is manufactured by folding the packing unit 30 in two, the center line position of the first surface 31 can be ensured to be aligned with the bottom of the outer bag 40. After the packing bag 400 is manufactured by using the cushion unit 30, the packing bag 400 itself is thin in size, and the transportation cost can be reduced. When an object is placed in or the first and second sub-faces 33, 34 of the second face 32 are pushed to spread by an external force, the first and second sub-faces 33, 34 expand in the thickness direction to form the buffer layer 321. When the first sub-surface 33 and the second sub-surface 34 are expanded, the first sub-surface 33 is influenced by pulling forces from two ends of the first sub-surface 33, namely the pulling force from one end of the first surface 31 and the pulling force from the center line of the second surface 31, so that the first sub-surface 33 can be pulled to be unfolded more easily; the same also makes it easier to unfold the second partial surface 34.
