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.

[0007] 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 provides robust air cushioning protection for each item to be packaged by setting slots of matching size for different items to be packaged.

[0008] 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 has multiple slots, each slot having not only a positioning heat-sealing point but also a shaping heat-sealing point, thereby enabling each slot to maintain a stable shape and further improving the cushioning and protection effect of the slot-type air packaging device.

[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.

[0013] One advantage of the present invention is that it provides a slot-type air packaging device and a packaging method thereof, wherein the slot-type air packaging device can be automatically inflated and integrally formed, thereby making the slot-type air packaging device simple to operate and convenient to use.

[0014] One advantage of the present invention is that it provides a slot-type air packaging device and a packaging method thereof, wherein the packaging method is simple and easy to operate, and requires little skill from the operator, thereby further improving the applicability of the slot-type air packaging device.

[0015] One advantage of the present invention is that it provides a slot-type air packaging device and a packaging method thereof, wherein the packaging method enables multiple items to be packaged to be packaged simultaneously, thereby improving the packaging efficiency of the items to be packaged and saving packaging time.

[0016] To achieve at least one of the above-mentioned advantages, the present invention provides a slot-type air packaging device for providing cushioning protection for at least one item to be packaged. The slot-type air packaging device is an air cushioning device, comprising a base and a support structure, wherein the support structure extends integrally from and is supported by the base, and the support structure has at least one slot for placing the item to be packaged, wherein the item to be packaged can be secured by the slot and simultaneously supported by the support structure and the base.

[0046] 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.

[0047] 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 this 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 this invention.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] like Figures 2 to 6 As 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] In addition, such as Figure 4a As shown, 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 formed shape of the support structure 12'. Or as... Figure 4b As shown, by changing the position and number of the positioning heat sealing line 1104", the support structure 12" is made to be W-shaped and so on.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] In a first embodiment of the present invention, the plurality of slots 120 are of the same size, thereby providing support for the plurality of items 20 to be packaged that are of the same or similar size. The inflatable columns disposed on both sides of the slots 120 are of the same size, thereby providing the same cushioning protection effect for the items 20 to be packaged that are disposed in the slots 120.

[0064] like Figure 3a As shown, in a modified embodiment of the slot-type air packaging device 10' of the present invention, those skilled in the art can set the size of the slot 120' according to the specific structure of the item 20 to be packaged. In other words, if it is necessary to provide cushioning protection for items 20 of different sizes using the slot-type air packaging device 10' of the present invention, those skilled in the art can set the slot 120' to different corresponding sizes according to the corresponding sizes of the different items 20 to be packaged, thereby providing support for the different items 20 to be packaged.

[0065] In addition, those skilled in the art can also adjust the size of the inflatable columns on both sides of any of the slots 120' according to the actual situation. For example, the size of the inflatable columns on both sides of any of the slots 120' can be set to be different according to the actual size of the item to be packaged 20, so as to provide different cushioning protection effects for different items to be packaged 20.

[0066] In addition, such as Figure 3b As shown, as another variation of the first embodiment of the slot-type air packaging device 10” of the present invention, those skilled in the art can also change the setting of the slot 120” according to the actual situation, for example, by setting two or more air columns between every two slots 120”, thereby further improving the buffer protection effect on the items to be packaged located in the slot 120”.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] In the first embodiment of the present invention, the air columns located on both sides of the slot 120 are of the same size, thereby providing the same cushioning protection effect for the items to be packaged located in different slots 120.

[0082] Furthermore, as a modified embodiment of the first embodiment of the present invention, the size of the air columns located on both sides of the slot 120 can be adjusted according to different items to be packaged.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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:

[0089] 1001: Inflate the slotted air packaging device 10 to form a three-dimensional structure;

[0090] 1002: Forming the slot 120; and

[0091] 1003: Insert the item to be packaged 20 into the slot 120.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and any variations or modifications may be made to the implementation of the present invention without departing from the stated principles.
