Description

Technical Field

[0001] This invention relates to a packaging structure, and more specifically, to a slot-type air packaging device and its packaging method. Background Technology

[0002] With the changing lifestyles of modern society and the rapid development of the logistics industry, many goods are traded through logistics, such as electronic products, chemical products, pharmaceutical products, ceramics, glass and other daily necessities. During the storage or transportation of these goods, it is inevitable that they will be squeezed, collided or dropped, resulting in product damage or deformation and causing losses to people. In particular, the economic losses caused by the damage or deformation of high-value items are even greater.

[0003] To protect products, packaging boxes and other materials are used before storage or transportation to provide cushioning and protection. Commonly used packaging boxes include cardboard boxes and inflatable bags. Traditional cardboard boxes do not provide adequate cushioning and offer insufficient protection. For example, before transporting laptops, they are often wrapped in multiple layers of foam and flexible plastic before being placed in a box. While this traditional packaging method does achieve good drop and impact resistance, it undoubtedly increases transportation costs and is extremely inconvenient, wasting time, reducing efficiency, and increasing labor costs—it no longer meets the needs of modern transportation. Furthermore, because both boxes and cushioning materials like foam are used, a large amount of these materials are discarded after delivery, burdening users and harming the environment.

[0004] In light of this situation, those skilled in the art have invented an air packaging bag, which is formed by heat-sealing and folding two or more plastic films and then inflating them. This air packaging bag often has a containment space in which the item to be packaged can be placed, thereby providing cushioning protection for the item to be packaged during transportation and storage.

[0005] However, this type of air packaging bag also has its drawbacks. First, an air packaging bag only forms a single containment space. To avoid collisions between items to be packaged, one air packaging bag can often only provide cushioning protection for one item, which increases packaging costs. In addition, most existing air packaging devices are general-purpose products, so products with different shapes cannot be well matched with existing air packaging devices, resulting in the items to be packaged not being properly covered by the air packaging device, and thus failing to provide comprehensive air cushioning protection. Summary of the Invention

[0006] One advantage of this invention is that it provides a slot-type air packaging device and packaging method for providing cushioning protection for flat items to be packaged. The slot-type air packaging device can simultaneously provide comprehensive air cushioning protection for two or more items to be packaged, thereby improving packaging efficiency and reducing packaging costs.

[0009] One advantage of the present invention is that it provides a slot-type air packaging device and a packaging method thereof, wherein the slots in the slot-type air packaging device are non-inflatable structures, which not only facilitates the insertion of the items to be packaged into the slots, but also reduces the amount of air required for the slot-type air packaging device.

[0010] One advantage of the present invention is that it provides a slot-type air packaging device and a packaging method thereof, wherein the slot shape and size of the slot in the slot-type air packaging device can be set according to the shape and size of the item to be packaged, thereby enabling the slot-type air packaging device to provide cushioning protection for items of different shapes and sizes to be packaged simultaneously.

[0011] One advantage of the present invention is that it provides a slot-type air packaging device and a packaging method thereof, wherein the slot width in the slot-type air packaging device can be set to be uniform or different, thereby providing cushioning protection for items to be packaged of the same or different thicknesses at the same time.

[0012] One advantage of the present invention is that it provides a slot-type air packaging device and packaging method thereof, wherein the slot-type air packaging device is configured with a tear line so that the item to be packaged can be directly placed in the slot without the need to cut the slot with other tools or steps, thereby saving packaging costs and packaging time for the item to be packaged.

[0072] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0073] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the invention.

[0074] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0075] This invention primarily provides a slot-type air packaging device 10 for providing cushioning protection for multiple items 20 to be packaged. Figures 1 to 7 The diagram shown is a structural schematic of a first embodiment of the slot-type air packaging device 10 of the present invention. In the first embodiment of the present invention, the slot-type air packaging device 10 includes a base 11 and a support structure 12, wherein the support structure 12 extends integrally from and communicates with the base 11, thereby enabling the slot-type air packaging device 10 to complete the inflation of the base 11 and the support structure 12 in one operation.

[0076] In detail, one end of the support structure 12 extends along the inflation direction to one side of the base 11 and communicates with the base 11, and the other end of the support structure 12 along the inflation direction is heat-sealed to the base 11, so that the support structure 12 is supported by the base 11.

[0077] like Figures 2 to 6As shown, after inflation, the base 11 becomes a groove shape and has a receiving cavity 100. The support structure 12 extends toward the receiving cavity 100 of the base 11 and is supported in the receiving cavity 100 of the base 11. The support structure 12 has one or more slots 120 to place multiple items to be packaged 20 and to secure the items to be packaged 20. The one or more slots 120 are spaced apart from each other on the support structure 12, so that multiple items to be packaged 20 are spaced apart from each other and simultaneously supported by the support structure 12 and the base 11. After inflation, the base 11 is bent into a near-right-angle structure, and correspondingly, the receiving cavity 100 forms a near-cubic-piezoelectric cavity, so that the regularly flat items to be packaged 20 can be accommodated in the receiving cavity 100 of the base 11.

[0078] Furthermore, the base 11 is provided with a first heat-sealing line 1101, a second heat-sealing line 1102, and a third heat-sealing line 1103 to divide the base 11 into a first part 111, a second part 112, and a third part 113. The base 11 can be bent relative to the first heat-sealing line 1101, the second heat-sealing line 1102, and the third heat-sealing line 1103 to form the first part 111, the second part 112, and the third part 113 at an angle perpendicular to each other, thereby enabling the base 11 to form the receiving cavity 100, wherein the second part 112 is the bottom of the receiving cavity 100, and the first part 111 and the third part 113 are the sides of the receiving cavity 100.

[0079] One end of the support structure 12 extends from the third heat-sealing line 1103 on the base 11, and the other end of the support structure 12 is heat-sealed to the first portion 111 on the base 11 via a fourth heat-sealing line 1105, so that the support structure 12 and the second portion 112 of the base 11 are positioned opposite each other. The length of the support structure 12 is greater than the length of the second portion 112 of the base 11, and the support structure 12 has a positioning heat-sealing line 1104. The support structure 12 is heat-sealed to the second portion 112 of the base 11 by the positioning heat-sealing line 1104, thereby supporting the support structure 12 in the receiving cavity 100.

[0080] Furthermore, in the first embodiment of the present invention, the positioning heat-sealing line 1104 is heat-sealed in the middle of the second part 112 to divide the support structure 12 into a first support part 121 and a second support part 122, wherein the length of the first support part 121 of the support structure 12 is greater than the length of the second support part 122, thereby forming the support structure 12 into an approximately “V” shaped structure.

[0081] In addition, those skilled in the art can adjust the heat-sealing position of the other end of the support structure 12 and the first part 111 on the base 11, and / or adjust the specific position of the positioning heat-sealing line 1104 according to the actual situation, thereby changing the final forming shape of the support structure 12. For example, by changing the position and number of the positioning heat-sealing line 1104, the support structure 12 can be made to be approximately wavy or W-shaped.

[0082] In other words, as long as the same or similar technical solutions are adopted based on the above disclosure of the present invention, the same or similar technical problems are solved, and the same or similar technical effects are achieved, they all fall within the protection scope of the present invention, and the specific embodiments of the present invention are not limited thereto.

[0083] Since the slots 120 are spaced apart from the support structure 12, and the support structure 12 is supported by the base 11, when the item to be packaged 20 is inserted into the slot 120, both sides of the item to be packaged 20 are clamped by the support structure 12, and the bottom of the item to be packaged 20 is supported by the second part 112 of the base 11, thereby providing all-round protection for the item to be packaged 20.

[0084] In a first embodiment of the present invention, the width of the slot 120 is the same as the width of the item to be packaged 20, so that the item to be packaged 20 can be securely held and fixed by the support structure 12 after being inserted into the slot 120.

[0085] Furthermore, the positioning heat-sealing line 1104 on the support structure 12 includes a positioning point 11041 and a shaping point 11042, wherein the positioning point 11041 is used to position the positioning heat-sealing line 1104 on the second part 112 on the base 11, and the shaping point 11042 is used to fix the shape and position of the air column on the support structure 12, so that the slot-type air packaging device 10 will not deform after inflation, nor will it affect the shape and structure of the slot 120.

[0086] Specifically, the positioning point 11041 is set on the positioning heat-sealing line 1104 and located on the air buffers on both sides of the slot 120, thereby heat-sealing and positioning the support structure 12 in the middle of the second part 112 on the base 11. The shaping point 11042 is set on both sides of the positioning point 11041 and fixes the edges of the air buffers on both sides of the slot 120, so that the slot-type air packaging device 10 can maintain the stability of the position of the slot 120 and not deform after inflation, thereby facilitating the insertion of the item to be packaged 20 into the slot 120.

[0087] In addition, those skilled in the art can also fix the support structure 12 to other parts of the base 11 or to other positions of the second part 112 via the positioning heat sealing line 1104, all of which fall within the protection scope of the present invention, and the specific embodiments of the present invention are not limited thereto.

[0088] In a first embodiment of the slot-type air packaging device 10 of the present invention, the slots 120 are spaced apart, and an air column is provided on both sides of each slot 120, that is, an air column is provided between every two slots 120, thereby maximizing the number of slots 120 and thus increasing the packaging quantity of the slot-type air packaging decoration.

[0089] In addition, those skilled in the art can also change the arrangement of the slots 120 according to the actual situation, such as setting two or more air columns between every two slots 120, thereby further improving the buffer protection effect on the items 20 to be packaged located in the slots 120.

[0090] Furthermore, in the first embodiment of the slot-type air packaging device 10 of the present invention, the slot 120 is configured by setting a portion of the air column in the support structure 12 as a non-inflated structure, and providing a tear line structure 1211 on the non-inflated air column. Thus, during the process of inserting the item to be packaged 20 into the slot 120, the tear line structure 1211 is torn open by external force and the force of the item to be packaged 20 itself, thereby placing the item to be packaged 20 into the slot 120.

[0091] Furthermore, those skilled in the art may also configure the slot 120 with other structures, including but not limited to reserved opening structures. As long as the same or similar technical solutions are adopted on the basis of the above disclosure of the present invention, the same or similar technical problems are solved, and the same or similar technical effects are achieved, they all fall within the protection scope of the present invention. The specific embodiments of the present invention are not limited thereto.

[0092] Since the inflatable air column in the slot-type air packaging device 10 of the present invention is set as a regular strip structure, the formed air buffer body will also be a regular strip shape, so that the slot 120 located between each of the air buffer bodies is also a regular groove structure. Therefore, the slot-type air packaging device 10 of the present invention is suitable for providing cushioning protection for flat and fragile items.

[0093] However, the specific scope of protection of the present invention is not limited to this. The shape of the slot 120 can also be changed by changing the shape of the air buffer, so that the slot-type air packaging device 10 of the present invention can also provide cushioning protection for other shaped items 20 to be packaged.

[0094] Furthermore, in the first embodiment of the present invention, the length of the second part 112 of the base 11 is not less than the width of the item to be packaged 20, and the length of the third part 113 of the base 11 and the length of the first part 111 are not less than the height of the item to be packaged 20, so that after the base 11 is inflated to form a right-angled groove structure and a cuboid-like receiving cavity 100, the height and width of the receiving cavity 100 are not less than the height and width of the item to be packaged 20, respectively. This allows the item to be packaged 20 to be accommodated in the receiving cavity 100 and held by the slot 120, and all sides of the item to be packaged 20 except the top can be covered by the slot-type air packaging device 10.

[0095] like Figure 1 As shown, in the first embodiment of the present invention, the slot-type air packaging device 10 is an air buffer device, comprising one or more air buffer bodies, each of which is formed by a series of planar heat seals of a gas buffer material 130. The gas buffer material 130 includes a first gas storage membrane 1301 and a second gas storage membrane 1302, and a gas storage chamber 135 formed between the first gas storage membrane 1301 and the second gas storage membrane 1302, the gas storage chamber 135 being adapted to be filled with a certain amount of gas.

[0096] When the gas storage chamber 135 formed by the gas buffer material 130 is not filled with gas, the first gas storage membrane 1301 and the second gas storage membrane 1302 of the gas buffer material 130 are close to each other, and the gas buffer material 130 is in a planar state. When an appropriate amount of gas is filled into the gas storage chamber 135 of the gas buffer material 130, the first gas storage membrane 1301 and the second gas storage membrane 1302 separate from each other. The air buffer provides a buffering and protective function by means of the gas stored between the first gas storage membrane 1301 and the second gas storage membrane 1302.

[0097] The air buffer further includes an inflation channel 134 and at least one inflation valve 136. The inflation channel 134 connects the gas storage chamber 135 and the external environment, allowing external gas to enter the gas storage chamber 135 through the inflation channel 134 and the inflation valve 136, thereby enabling the air buffer to provide buffering and protection.

[0098] Furthermore, in the first embodiment of the slot-type air packaging device 10 of the present invention, the inflation valve 136 is a self-adhesive film inflation valve 136, that is, after the gas is filled into the gas storage chamber 135 through the inflation channel 134 and the inflation valve 136, the inflation valve 136 can automatically close the gas storage chamber 135, thereby preventing the gas in the gas storage chamber 135 from escaping through the inflation valve 136 and the inflation channel 134 after the inflation of the air buffer body is stopped.

[0099] The gas buffer material 130 further includes a planar molding unit for heat-sealing the first gas storage film 1301 and the second gas storage film 1302 together, thereby forming the gas storage chamber 135 and the inflation channel 134 between the first gas storage film 1301 and the second gas storage film 1302, and enabling the gas filled into the gas storage chamber 135 to be retained in the gas storage chamber 135, thereby enabling the air buffer to provide buffer protection.

[0100] Furthermore, the gas buffer material further includes a three-dimensional molding unit 110, which is used to heat-seal the first gas storage film and the second gas storage film together, thereby forming the base 11 and the support structure 12.

[0101] The three-dimensional sealing unit 110 includes a first heat-sealing line 1101, a second heat-sealing line 1102, a third heat-sealing line 1103, a positioning heat-sealing line 1104, and a fourth heat-sealing line 1105, thereby forming a three-dimensional structure of the slot-type air packaging device 10 through the first heat-sealing line 1101, the second heat-sealing line 1102, the third heat-sealing line 1103, the positioning heat-sealing line 1104, and the fourth heat-sealing line 1105.

[0102] In the support structure 12, the gas storage chamber formed by the first gas storage membrane and the second gas storage membrane is a partially inflated and partially uninflated structure. In other words, the gas storage chambers in the first support portion 121 of the support structure 12 and the third portion 113 of the base 11 are not completely connected. Instead, the gas storage chamber at the slot 120 position is set as a non-connected structure by the third heat-sealing line 1103, so that gas cannot enter the gas storage chamber at the slot 120 position during inflation. This reserves the corresponding position of the slot 120, making it easier for the item to be packaged 20 to be placed smoothly into the slot 120 position.

[0103] In addition, those skilled in the art can modify the inflation structure of the above-mentioned support part according to actual needs. For example, the gas storage chamber at the location of the slot 120 can be set as a small air column structure, and the gas storage chambers on both sides of the slot 120 can be set as large air column structures, as long as sufficient space is reserved for the slot 120 and the item to be packaged 20 can be smoothly placed in the slot 120. In other words, as long as the same or similar technical solutions are adopted based on the above disclosure of the present invention, the same or similar technical problems are solved, and the same or similar technical effects are achieved, they all fall within the protection scope of the present invention, and the specific embodiments of the present invention are not limited thereto.

[0104] like Figure 3 As shown, it should be emphasized that in the first embodiment of the slot-type air packaging device 10 of the present invention, the support structure 12 further includes a connecting portion 123, which is disposed between the second support portion 122 of the support structure 12 and the first portion 111 of the base 11. The three-dimensional sealing unit 110 further includes a fifth heat-sealing line 1106, which is located between the second support portion 122 and the connecting portion 123 of the support structure 12 and separates the second support portion 122 and the connecting portion 123 through the fifth heat-sealing line 1106.

[0105] The connecting portion 123 is a non-inflatable structure, meaning the fifth heat-sealing line 1106 completely isolates the second support portion 122 and the connecting portion 123 in the support structure 12, preventing gas from being filled into the gas storage chamber of the connecting portion 123. The connection portion 123 facilitates a smoother connection between the second support portion 122 in the support structure 12 and the first portion 111 in the base 11, preventing the first portion 111 of the base 11 from being deformed by the gas storage chamber of the second support portion 122 in the support structure 12, thereby further improving the structural stability of the slot-type air packaging device 10 of the present invention.

[0106] Furthermore, due to the arrangement of the connecting part 123, there is a buffer space between the support structure 12, the second support part 122, and the first part 111 of the base 11, thereby ensuring that the first part 111 of the base 11 has a certain degree of freedom, so that the item to be packaged 20 is inserted into the slot 120 more smoothly.

[0107] Furthermore, such as Figure 7 The diagram shown is a structural schematic of a modified embodiment of the slot-type air packaging device 10 of the present invention. In this modified embodiment, the slot-type air packaging device 10A of the present invention can also be used in a stacked manner. If the height of the item to be packaged 20A is relatively high, two slot-type air packaging devices 10A of the present invention can be stacked and used to package the item to be packaged 20A towards both ends, thereby completely covering the item to be packaged 20A and providing complete air cushioning protection for the larger item to be packaged 20A.

[0108] Furthermore, since the planar sealing unit and the three-dimensional sealing unit 110 of the present invention have made complete plans for all heat-sealing parts, and have made precise settings for the specific heat-sealing positions without affecting the molding of the slot-type air packaging device 10, the slot-type air packaging device 10 of the present invention can achieve one-time inflation molding and can be continuously and automatically inflated on the production line, thereby improving the inflation efficiency of the slot-type air packaging device 10 of the present invention.

[0109] like Figure 8 As shown, the present invention further provides a packaging method for a slot-type air packaging device 10, used to package one or more items 20 to be packaged. The packaging method of the slot-type air packaging device 10 includes the following steps:

[0110] 1001: Inflate the slotted air packaging device 10 to form a three-dimensional structure;

[0111] 1002: Forming the slot 120; and

[0112] 1003: Insert the item to be packaged 20 into the slot 120.

[0113] In step 1001, the inflation process of the slot-type air packaging device 10 can be completed during use, before use, or immediately after the slot-type air packaging device 10 is processed. The packaging method of the slot-type air packaging device 10 of the present invention does not limit the inflation time and the order of inflation steps of the slot-type air packaging device 10.

[0114] like Figure 1 and Figure 2 As shown, in step 1002, the slot 120 is formed during the production of the slot-type air packaging device 10, or it is formed by tearing open the gas storage chamber at the corresponding position during use to allow the slot 120 to leak out. In the first embodiment of the present invention, the slot 120 is pre-formed during the production of the slot-type air packaging device 10 by setting multiple tear line structures 1211 at the corresponding position. However, the packaging method of the slot-type air packaging device 10 of the present invention is not limited to this. As long as, based on the above disclosure of the present invention, those skilled in the art adopt the same or similar technical solutions as the present invention, solve the same or similar technical problems as the present invention, and achieve the same or similar technical effects as the present invention, they all fall within the protection scope of the present invention.

[0115] In step 1003, the item to be packaged 20 can be inserted into the slot 120 through various means, such as automated fixing by machine or manual fixing. Furthermore, the fixing method of the item to be packaged 20 is also related to the structure of the slot-type air packaging device 10. In the first embodiment of the present invention, since the slot 120 in the slot-type air packaging device 10 adopts a tear line structure 1211, the tear line structure 1211 must be separated by external force to expose the slot 120, thereby fixing the item to be packaged 20 into the slot 120. If the structure of the slot 120 in the slot-type air packaging device 10 is changed, the action of inserting the item to be packaged 20 into the slot 120 in step 1003 may also change accordingly, but all of these changes fall within the scope of protection of the present invention.

[0116] In addition, it should be understood that the features in the various embodiments of the present invention can be applied to other embodiments, that is, the features of all these embodiments can be appropriately combined to enable the air packaging device 10 of the present invention to provide a multi-level cushioning effect.

[0117] It should be noted that in the first preferred embodiment of the present invention described above, the tear line structure 1211 is an easy-tear line formed by cutting or punching, and the easy-tear line is correspondingly formed on the first gas storage membrane 1301 and the second gas storage membrane 1302. Therefore, when the packaged item is inserted into the packaging bag, the slot 120 can be opened through the tear line structure 1211. That is, in this preferred embodiment of the present invention, the slot 120 is connected by the easy-tear line before it is opened, maintaining the integrity of the packaging bag, while in use, the tear line structure 1211 is broken to open the opening of the slot 120. Those skilled in the art will understand that in this preferred embodiment of the present application, the easy-tear line can be packaged according to the size of the packaged item.

[0118] Referring to the accompanying drawings of this invention Figures 9 to 13B As shown, a slot-type air packaging device 10B according to a second preferred embodiment of this application is described below. The slot-type air packaging device 10B is suitable for packaging sheet-like items 20, such as computers, tablets, photovoltaic devices, chips, and other valuable items. During packaging, the item 20 is inserted, or partially inserted, into the slot-type air packaging device 10B, which provides cushioning and protection for the item 20. The slot-type air packaging device 10B includes a base 11B and a support structure 12B, wherein the support structure 12B extends integrally from and communicates with the base 11B, thereby enabling the slot-type air packaging device 10B to inflate both the base 11B and the support structure 12B in one operation.

[0119] In this preferred embodiment of the present invention, the structure and function of the support structure 12B are the same as those of the support structure 12 in the first preferred embodiment described above, and will not be repeated here. The difference lies in the base 11B. One end of the support structure 12B extends along the inflation direction to one side of the base 11B and communicates with the base 11B. The other end of the support structure 12B along the inflation direction is heat-sealed to the base 11B, thereby supporting the support structure 12B by the base 11B.

[0120] Similar to the first preferred embodiment described above, the base 11B is recessed and has a receiving cavity 100B. The support structure 12B extends toward and is supported within the receiving cavity 100B of the base 11B. The support structure 12B has one or more tear lines 1211B, which, when torn or opened, form slots 120B. These slots 120B can hold one or more of the items to be packaged 20 and secure them. One or more slots 120B are spaced apart on the support structure 12B, thus spacing the multiple items to be packaged 20 apart and simultaneously supporting them with the support structure 12B and the base 11B. It should be noted that in this preferred embodiment of the present application, at least one air column is spaced between two adjacent slots 120B. The air columns spaced between the slots 120B provide sufficient spacing and effective cushioning for the items to be packaged 20.

[0121] After inflation, the base 11B is bent into a near-right-angled "U"-shaped structure or into a near-triangular support structure with a larger upper and lower end. Correspondingly, the receiving cavity 100B forms a near-cubic-piece cavity, thereby allowing the regularly flattened item to be packaged 20 to be accommodated in the receiving cavity 100B of the base 11B.

[0122] The base 11B is further provided with a first heat-sealing line 1101B, a second heat-sealing line 1102B, and a third heat-sealing line 1103B, dividing the base 11B into a first part 111B, a second part 112B, and a third part 113B that are sequentially connected. After inflation, the base 11B forms the first part 111B, the second part 112B, and the third part 113B at positions corresponding to the first heat-sealing line 1101B, the second heat-sealing line 1102B, and the third heat-sealing line 1103B at angles that are perpendicular to each other or inclined inward, thereby enabling the base 11B to form the receiving cavity 100B. The second part 112B is located at the bottom of the receiving cavity 100B, and the first part 111B and the third part 113B are respectively located on the sides of the receiving cavity 100B.

[0123] It is worth mentioning that, in this preferred embodiment of the present invention, the first heat-sealing line 1101B, the second heat-sealing line 1102B and the third heat-sealing line 1103B are formed on the heat-sealing point or heat-sealing block of the base 11B by a heat-sealing process, and the base 11B is formed into a specific shape and structure by the heat-sealing lines.

[0124] One end of the support structure 12B extends from the third heat-sealing line 1103B on the base 11B, and the other end of the support structure 12B is heat-sealed to the first portion 111B on the base 11B via at least one fourth heat-sealing line 1105B, such that the support structure 12B and the second portion 112B of the base 11B are disposed opposite each other. It is understood that the length of the support structure 12B is greater than the length of the second portion 112B of the base 11B, and the support structure 12B has a positioning heat-sealing line 1104B. The support structure 12B is heat-sealed to the second portion 112B of the base 11B by the positioning heat-sealing line 1104B, thereby supporting the support structure 12B within the receiving cavity 100B.

[0125] The positioning heat-sealing line 1104B is formed in the middle of the second part 112B. The positioning heat-sealing line 1104B divides the support structure 12B into a first support part 121B and a second support part 122B. The length of the first support part 121B of the support structure 12B is greater than the length of the second support part 122B, thereby forming the support structure 12B into an approximate "V", "W" or wave-shaped structure.

[0126] Since the slots 120B are formed at intervals in the support structure 12B, and the support structure 12B is supported by the base 11B, when the item to be packaged 20 is inserted into the slot 120B, both sides of the item to be packaged 20 are clamped by the support structure 12B, and the bottom of the item to be packaged 20 is supported by the second part 112B of the base 11B, thereby providing all-round protection for the item to be packaged 20.

[0127] Preferably, the slots 120B are spaced apart, and an air column is provided on both sides of each slot 120B, that is, an air column is provided between every two slots 120B, thereby maximizing the number of slots 120B and thus increasing the packaging quantity of the slot-type air packaging decoration.

[0128] The length of the second part 112B of the base 11B is not less than the width of the item to be packaged 20, and the length of the third part 113B and the length of the first part 111B of the base 11B are not less than the height of the item to be packaged 20. This is so that after the base 11B is inflated to form a right-angled groove structure and a cuboid-like receiving cavity 100B, the height and width of the receiving cavity 100B are not less than the height and width of the item to be packaged 20, respectively. This allows the item to be packaged 20 to be accommodated in the receiving cavity 100B and held by the slot 120B, and all sides of the item to be packaged 20 except the top can be covered by the slot-type air packaging device 10B.

[0129] The slot-type air packaging device 10B is an air buffer device, comprising one or more air buffer bodies, each of which is formed by a series of planar heat seals of a gas buffer material 130B. The gas buffer material 130B includes a first gas storage membrane 1301B and a second gas storage membrane 1302B, and a gas storage chamber 135B formed between the first gas storage membrane 1301B and the second gas storage membrane 1302B, the gas storage chamber 135B being adapted to be filled with a certain amount of gas.

[0130] It is understood that, in this preferred embodiment of the present invention, the heat-sealing lines (first heat-sealing line, second heat-sealing line, third heat-sealing line, and fourth heat-sealing line) are formed on the gas buffer material by a heat-sealing process, that is, the first gas storage film 1301B and the second gas storage film 1302B are bonded to each other by the heat-sealing lines, thereby forming the slot-type air packaging device 10B from a planar packaging bag structure into a three-dimensional structure suitable for accommodating the item to be packaged 20 after inflation.

[0131] The air buffer further includes an inflation channel 134B and at least one inflation valve 136B. The inflation channel 134B connects the gas storage chamber 135B and the external environment, allowing external gas to enter the gas storage chamber 135B through the inflation channel 134B and the inflation valve 136B, thereby enabling the air buffer to provide buffering and protection.

[0132] The gas buffer material further includes a three-dimensional sealing unit 110B, which is used to heat-seal the first gas storage film and the second gas storage film together, thereby forming the base 11B and the support structure 12B. The three-dimensional sealing unit 110B includes a first heat-sealing line 1101B, a second heat-sealing line 1102B, a third heat-sealing line 1103B, a positioning heat-sealing line 1104B, and a fourth heat-sealing line 1105B, thereby forming a three-dimensional structure of the slot-type air packaging device 10B through the first heat-sealing line 1101B, the second heat-sealing line 1102B, the third heat-sealing line 1103B, the positioning heat-sealing line 1104B, and the fourth heat-sealing line 1105B.

[0133] In the support structure 12B, the gas storage chamber 135B formed by the first gas storage membrane 1301B and the second gas storage membrane 1302B is a partially inflated and partially uninflated structure. In other words, the gas storage chambers in the first support portion 121B of the support structure 12B and the third portion 113B of the base 11B are not fully connected. Instead, the gas storage chamber 135B at the slot 120B position is set as a non-connected structure by the third heat-sealing line 1103B, so that gas cannot enter the gas storage chamber at the slot 120B position during inflation. This reserves the corresponding position of the slot 120B, making it easier for the item to be packaged 20 to be placed smoothly into the slot 120B position.

[0134] It should be noted that when the item to be packaged 20 is inserted into the slot 120B of the slot-type packaging bag 10B, the item to be packaged 20 is clamped in the slot 120B by the support structure 12B, and the air column structures on both sides of the slot 120B of the support structure 12B compress the item to be packaged 20 in an inflated state. Therefore, the item to be packaged 20 is clamped in the slot 120B by the support structure 12B. The base 11B is located above the support structure 12B, and supports the support structure 12B and the item to be packaged 20 clamped by the support structure 12B.

[0135] It is understood that, in this preferred embodiment of the present invention, the support structure 12B of the slot-type packaging bag 10B is above the base 11B and clamps the item to be packaged 20 in the receiving cavity 100B of the base 11B. The slot 120B of the support structure 12B and the air column structures on both sides of the slot 120B restrict the movement of the item to be packaged 20 and prevent collisions between adjacent items. That is, the support structure 12B serves as a support and lateral protection.

[0136] At least a portion of the structure of the item 20 to be packaged is covered by the first portion 111B, the second portion 112B, and the third portion 113B of the base 11B. Specifically, in this preferred embodiment of the application, the first portion 111B of the base 11B covers the right side (left side) of the item 20 to be packaged; the second portion 112B of the base 11B covers the lower side (upper side) of the item 20 to be packaged; and the third portion 113B of the base 11B covers the left side (right side) of the item 20 to be packaged. Therefore, the base 11B covers the outside of the item 20 to be packaged, and in the inflated state, the base 11B serves to cushion and protect the internal contents of the item 20 to be packaged.

[0137] Ideally, the item to be packaged 20 is held in the receiving cavity 100B of the base 11B by the support structure 12B. The item to be packaged 20 is also supported by an air column structure of the base 11B, which provides cushioning and protection to the sides of the item. However, in the inflated state, the support structure 12B of the slot-type air packaging device 10B cannot completely fix the item to be packaged 20 in the receiving cavity 100B inside the base 11B. When the item to be packaged 20 is wrapped by the slot-type packaging bag 10B, the item's own weight and the structural characteristics of the slot 120B of the support structure 12B can cause a slight positional shift in the item. This positional shift can have a serious impact on the item.

[0138] After the slot-type air packaging device 10B is inflated, the base 11B is heat-sealed to form multiple spaced-apart air columns (airbag structures), and a groove is formed between two adjacent air columns above (inner side) of the heat-sealing line. It is understood that this groove structure is formed by the heat-sealing line, and the groove corresponds to the thinnest part of the base 11B. Since the air column structures of the base 11B are roughly cylindrical after inflation, this cylindrical air column structure guides the item to be packaged 20 to slide towards the groove, i.e., lateral displacement. In some cases, the item to be packaged 20 may even be stuck by the air columns of the base 11B, and the item to be packaged 20 may be stretched or misaligned and twisted by the base 11B, resulting in displacement and deformation. Simply put, the slot-type air packaging device 10B may also damage or even destroy the item to be packaged after inflation. In addition, when the item to be packaged 20 is stuck in the groove between the two air columns, the buffering and protective function of the slot-type air packaging device 10B will be greatly reduced because the corresponding position of the heat seal line is very thin, which seriously affects the safety and integrity of the item to be packaged during transportation.

[0139] Based on the above situation, according to the above-mentioned technical problems of the present invention, the base 11B of the slot-type air packaging device 10B of the second preferred embodiment of the present invention includes a plurality of air columns 114B and further provides a plurality of air column heat sealing lines 115B, wherein at least one air column heat sealing line 115B is formed between two adjacent air columns 114B, and the air column heat sealing line 115B separates two adjacent air columns 114B, so that the two adjacent air columns are isolated from each other.

[0140] It is worth mentioning that, in this preferred embodiment of the present invention, the air column 114B of the base 11B and the air column heat-sealing line 115B spaced between the air columns 114B extend longitudinally, and the first portion 111B, the second portion 112B, and the third portion 113B of the base 11B are formed by the air columns 114B. The air column heat-sealing line 115B of the base 11B is formed on the first gas storage film 1301B and the second gas storage film 1302B of the gas buffer material 130B, and the air column 114B with an independent gas storage space is formed by the air column heat-sealing line 115B.

[0141] like Figure 10 and Figure 11As shown, when the slot-type air packaging device 10B is in an inflated state, multiple membrane grooves 116B are formed on the inner side of the air column 114B by the first gas storage membrane 1301B or the second gas storage membrane 1302B, wherein the opening direction of the membrane grooves 116B faces the receiving cavity 100B of the base 11B. It can be understood that when the slot-type air packaging device 10B is not inflated, the first gas storage membrane 1301B and the second gas storage membrane 1302B of the gas cushioning material 130B are in a flat state, and the membrane grooves 116B are not present. The air column heat-sealing line 115B is located below the membrane grooves 116B; therefore, the air column heat-sealing line 115B of the base 11B directly affects the shape and structure of the air column 114B and the membrane grooves 116B.

[0142] In this preferred embodiment of the invention, the air column heat-sealing line 115B of the base 11B has a non-linear structure in the longitudinal direction. In other words, in this preferred embodiment of the invention, the air column heat-sealing line 115B of the base 11B is implemented as a curved heat-sealing line, a zigzag heat-sealing line, or other linear structures with regular or irregular shapes. The air column 114B and the membrane groove 116B formed by the air column heat-sealing line 115B have a non-cylindrical structure to prevent the item to be packaged 20 from being stuck in the membrane groove 116B by the air columns 114B on both sides of the air column heat-sealing line 115B.

[0143] Preferably, in this preferred embodiment of the present application, the air column structure corresponding to the support structure 12B is a cylindrical structure, that is, the longitudinal heat seal line formed at the support structure 12B is a straight heat seal line, and the air column structure formed by the support structure 12B longitudinally holds the packaged item 20B within the receiving cavity 100B of the base 11B.

[0144] like Figure 11 As shown, in this preferred embodiment of the application, in the inflated state, the item to be packaged 20 (such as a computer, monitor, tablet computer, chip, photovoltaic, etc.) is wrapped by the slot-type air packaging device 10B, and the item to be packaged 20 is clamped and held within the receiving cavity 100B of the base 11B by the support structure 12B. Since the air column heat-sealing line 115B of the base 11B is a non-linear structure, the air column 114B formed by the air column heat-sealing line 115B is a non-cylindrical structure to prevent the item to be packaged 20 from being stuck in the membrane groove 116B by two adjacent air columns 114B.

[0145] Figure 12A and Figure 12B Two different embodiments of the air column heat sealing line 115B of the base 11B of the present invention are shown. For example... Figure 12A As shown, in this preferred embodiment of the present invention, the air column heat-sealing line 115B of the base 11B is curved, and the air column 114B formed by the air column heat-sealing line 115B is a curved airbag structure. When the item to be packaged 20 is wrapped by the base 11B, the sides (left side, right side, and bottom side) of the item to be packaged 20 will not be guided towards the membrane groove 116B by the air column 114B, thus preventing the item to be packaged 20 from being stuck between two adjacent air columns 114B.
