Description

Technical Field

[0001] The present invention relates to the technical field of air column bags, and particularly relates to an N-type buffer air column structure. Background Art

[0002] Products such as televisions and monitors need to be frequently transported among various links involved in production and sales. During the transportation process, situations such as extrusion, collision, and dropping are inevitable. Since such products are fragile, in order to reduce damage, air column bags are usually filled in the packaging cartons of the products to achieve the purpose of buffering and shock absorption.

[0003] During packaging, the corner protection air column bag is often sleeved on the corners of the television. However, the existing N-type buffer air column structure still has deficiencies. For example, in order to prevent the air column bag from warping and deforming, the heat-sealed end of the N-type buffer air column structure cannot be completely heat-sealed, leaving a gap of a certain size. As a result, the corners of the television are extremely likely to be caught in the gap. When the impact on the corners is too large, the corners are likely to break through the gap, resulting in the exposure of the corners or the rupture of the air column, the decline of the buffer and shock absorption performance, and the corners of the television are extremely likely to be damaged, and the protection effect is not good. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an N-type buffer air column structure. One ends of the first outer wall, the second outer wall, and the inner wall are heat-sealed along the lip seal line to form a closed protection area, avoiding the exposure of the corners of the television, and can avoid the decline of the buffer and shock absorption performance or the damage of the corners, and the protection effect is better.

[0005] The N-type buffer air column structure provided by the present invention includes a first outer wall, a second outer wall, and an inner wall inclined between the first outer wall and the second outer wall. One ends of the first outer wall, the second outer wall, and the inner wall are heat-sealed along the lip seal line to form a closed protection area for abutting against the corners of the television.

[0030] To enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Please refer to Figure 1 and Figure 8 , Figure 1 is the axonometric view of the N-type buffer air column structure provided by a specific embodiment of the present invention; Figure 2 is Figure 1 another view of Figure 3 is Figure 1 planar unfolded view; Figure 4 is Figure 3 state diagram after folding along the first folding line; Figure 5 is Figure 4 state diagram after folding along the second folding line; Figure 6 is Figure 5 state diagram after folding along the third folding line; Figure 7 is Figure 1State diagram when the inner and outer nodes are parallelly offset; Figure 8 is Figure 1 State diagram when the inner and outer nodes are obliquely offset.

[0032] An embodiment of the present invention discloses an N-type buffer air column structure, which is optimized based on the existing structure to improve the protection performance of the air column bag.

[0033] The present invention includes a first outer wall 1, a second outer wall 2 and an inner wall 3. The first outer wall 1 and the second outer wall 2 are arranged opposite to each other. The inner wall 3 is obliquely arranged between the first outer wall 1 and the second outer wall 2. Specifically, the upper end of the inner wall 3 is connected to the top end of the first outer wall 1 through a corner air column, and the lower end of the inner wall 3 is connected to the second outer wall 2 through a hammock 4. The first outer wall 1, the second outer wall 2 and the inner wall 3 are all in a flat shape, and each of them includes a number of air columns. The air columns of the three are separated by heat-sealing lines and are sequentially connected, which is convenient for inflation.

[0034] One end of the first outer wall 1, the second outer wall 2 and the inner wall 3 is heat-sealed along a lip seal line. The lip seal line is composed of two heat-sealing lines and is in a straight line shape, so that the air column bag forms a closed protection area. The outside of the lip seal line abuts against the inner wall of the carton. The closed protection area is located inside the lip seal line. The closed protection area is a closed area formed by the second outer wall 2, the inner wall 3 and the lip seal line. The corners of the TV can be placed in the closed protection area to avoid leaving gaps at the ends of the air column bag, so that the corners of the TV are completely wrapped by the closed protection area, avoiding the corners of the TV piercing the air column along the gap, reducing the risk of the buffer shock absorption performance decreasing and the corners being damaged, and the protection effect is better.

[0035] One end connection edge of the first outer wall 1, the second outer wall 2 and the inner wall 3 is connected by a three-wall heat-sealing line 6. It should be noted that the length of the three-wall heat-sealing line 6 should not be too long to avoid the first outer wall 1 and the second outer wall 2 being unable to closely adhere to the corners of the TV due to severe warping deformation, ensuring that the edges of the TV are in contact with the three-wall heat-sealing line 6, so that the entire air column bag can effectively play a buffer shock absorption role.

[0036] The second outer wall 2 and the inner wall 3 are connected by a hammock 4. The hammock 4 is in contact with the edge of the TV, avoiding the edge scratching the air column and being able to play a buffer shock absorption role when falling.

[0037] The inner wall 3 and the hammock 4 are connected by an inner-wall heat-sealing line 7. The three-wall heat-sealing line 6 and the inner-wall heat-sealing line 7 are collinear to form a lip seal line, using the lip seal line to block the gap between the second outer wall 2 and the inner wall 3, avoiding the corners of the TV from bursting through the second outer wall 2 or the inner wall 3 due to too large an impact force from the gap, and also preventing the corners from being bruised due to misalignment and exposure, and the protection effect is better.

[0038] The hammock 4 includes an inner hammock, which is arranged on the inner side of the inner wall heat-sealing line 7. The inner hammock is in the shape of a film and is used to abut against the edges and corners of the TV to prevent the edges and corners from scratching the air column. The inner hammock can be a co-extruded film, but is not limited to this. Specifically, the lower end of the inner wall 3 is heat-sealed to the second outer wall 2 through the heat-sealing point of the hammock 4. Of course, the length of the film at the lower end of the inner wall 3 can also be extended, so that the middle part of the extended film is heat-sealed to the second outer wall 2 through the heat-sealing point of the hammock 4. Of course, the installation methods of the hammock 4 are not limited to these two.

[0039] The hammock 4 also includes an outer hammock 41, which is arranged outside the inner wall heat-sealing line 7. The inner hammock and the outer hammock 41 use the inner wall heat-sealing line 7 as the critical line. The outer hammock 41 is against the inner wall of the carton. The outer hammock 41 includes a plurality of air columns, which are used to fill the space between the corners of the TV and the inner wall of the carton, so that the entire air column bag has sufficient buffering capacity, which can better protect the TV and effectively prevent the TV from being damaged after impact.

[0040] At least one layer of protective film is provided at the bottom of the hammock 4, and the protective film is used for protection and limiting to prevent the corners of the TV from piercing the hammock 4, and the protection is more reliable. Each layer of protective film can be a co-extruded film, but is not limited thereto. Specifically, the second outer wall 2 and the inner side wall 3 are heat-sealed at both ends of the protective film to form a multi-layer protective film.

[0041] The second outer wall 2 is connected to the bottom of the inner wall 3. The key point is that the second outer wall 2 is connected to the inner wall 3 through the positioning line 11. The positioning line 11 can limit the activity space of the second outer wall 2 to a certain extent, and make the second outer wall 2 drive the inner wall 3 to deviate synchronously through the positioning line 11, so as to prevent the TV from leaving the buffer space due to excessive impact, and the buffering is more reliable. Obviously, the setting of the positioning line 11 can make the protection area larger, the buffering effect better, and the aesthetics higher.

[0042] An air valve film 8 is provided at one end of the second outer wall 2 away from the inner wall 3, and the entire air column bag is inflated by the air valve film 8. The air valve film 8 is provided inside the second outer wall 2, and the second outer wall 2 can be used to cover the wrinkles of the air valve film 8, which has a better aesthetic appearance. In addition, moving the air valve film 8 to the second outer wall 2 makes it convenient for the cursor of the machine to accurately grasp the air valve film 8, which can effectively prevent the machine from running off, reduce the amount of scrap, and also facilitate and quickly find the inflation port, speed up the inflation efficiency, and avoid wasting time looking for the inflation port.

[0043] The present invention also includes a bottom side wall 5 fixedly connected between the first outer wall 1 and the second outer wall 2. The air columns of the first outer wall 1, the second outer wall 2 and the bottom side wall 5 are correspondingly connected. The upper ends of the first outer wall 1 and the bottom side wall 5 are connected through corner air columns. A group of bending nodes are respectively provided at the junction of the bottom side wall 5 and the first outer wall 1 and at the junction of the bottom side wall 5 and the second outer wall 2. The bending nodes can transform one air column into multiple air columns, and the bending parts have the required shape.

[0044] The plan view shall prevail. Figure 3 As shown, a flat film is provided with three folding lines, including a first folding line 101 and a second folding line 102 and a third folding line 103 respectively provided on both sides of the first folding line 101. The inner side wall 3 and the hammock 4 are first folded inwardly along the first folding line 101. Figure 4 Then fold the hammock 4 outward along the second folding line 102 so that the hammock 4 coincides with the plane of the inner wall 3, and the inner wall heat sealing line 7 is used to seal and connect the two, and after folding, Figure 5 Then, the second outer wall 2 is folded inwardly along the third folding line 103, and the second outer wall 2 is opposite to the inner wall 3. The first outer wall 1, the second outer wall 2 and the inner wall 3 are sealed by the three-wall heat sealing line 6. After folding, Figure 6 As shown; finally, the entire air column bag is inflated through the air valve membrane 8 provided on the second outer wall 2, so that each air column is filled with gas.

[0045] Each group of bending nodes includes outer nodes 9 and inner nodes 10 arranged on both sides of the lip seal line, the outer nodes 9 are close to one side of the carton, and the inner nodes 10 are close to the corner side of the TV. The outer nodes 9 and the inner nodes 10 are not collinear. Based on the plane development diagram, the width between the two rows of outer nodes 9 is greater than the width between the two rows of inner nodes 10. When the offset distance between the outer nodes 9 and the inner nodes 10 is a preset distance, the two sides of the bottom side wall 5 extend along a straight line after bending. By modifying the setting mode of the bending nodes, the local width of the bottom side wall 5 is prevented from being reduced due to the stretching of the three-wall heat sealing line 6, ensuring that the first outer wall 1, the bottom side wall 5 and the second outer wall 2 are all close to the inner wall of the carton, preventing the TV from shaking in the carton, and achieving the best buffering effect.

[0046] All the outer nodes 9 are distributed along a linear line, which can be called node parallel offset. Specifically, the outer nodes 9 can be set on the air columns of the first outer wall 1 and the second outer wall 2, and specifically include six outer nodes 9. Of course, the distribution of the outer nodes 9 is not limited to one method. All the outer nodes 9 can also be distributed along an arc line, which can be called node tilt offset. The distance between the outer node 9 located at the highest point of the arc line and the lip seal line is the smallest.

The description of the above embodiments is only used to help understand the method of the present invention and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope.
