Description

Technical Field

[0001] The present invention relates to the technical field of product packaging, and in particular to an inverted V-shaped corner protection cushioning air column bag. Background Art

[0002] Taking televisions and computer products as an example, all links involved in the storage and transportation of such products from production to sales require the use of various types of transfer vehicles. During the storage and transportation process, considering that such products often have defects such as heavy weight and fragility, they are inevitably squeezed, collided, and dropped, resulting in damage or deformation of the products. In order to reduce damage, corrugated cardboard boxes are often used to package such products, and cushioning materials such as air column bags are filled in the gaps of the cardboard boxes to achieve a better cushioning effect.

[0003] During packaging, corner cushioning air column bags are often put on the corners of televisions to wrap the corners and achieve better protection. For example, a Chinese patent (publication number CN111573007A) discloses a V-shaped corner cushioning air column bag and its manufacturing method, wherein the V-shaped corner cushioning air column bag comprises a first outer wall, a first inner wall, a second inner wall, a second outer wall and a side wall with multiple air columns, the length of the air columns of the first inner wall and the second inner wall is shorter than the length of the air columns of the first outer wall and the second outer wall, the first outer wall and the second outer wall are all connected to the side wall by bending nodes, the first outer wall and the first inner wall are connected to the ends of the first inner wall by head and tail heat sealing lines, and the connecting edges of the first outer wall, the first inner wall, the second inner wall and the second outer wall are connected by four-wall longitudinal heat sealing lines.

[0004] The V-shaped corner cushioning air column bag disclosed in the above patent is provided with an inverted V-shaped cover inside. The inverted V-shaped cover is formed by two oblique sides intersecting obliquely, ultimately forming a protective space of the inverted V-shaped cover. During packaging, the inverted V-shaped cover is put on the corner of the TV and fits the corner area of the TV. The width of the inverted V-shaped cover gradually narrows towards the corner of the TV, so that the inverted V-shaped cover can be closely attached to the corner of the TV, thereby covering the corner of the TV. However, it still has the following defects: since the width of the inverted V-shaped cover gradually widens in the direction away from the corner; therefore, in the direction away from the corner, the top of the inverted V-shaped cover gradually becomes lower, resulting in it being unable to be leveled with the edge of the corner area. In other words, in the direction away from the corner, the top of the inverted V-shaped cover has a downward inclination, which results in the two oblique sides of the inverted V-shaped cover being unable to be closely attached to the corresponding edge away from the corner, so that its overall wrapping effect on the corner area is still poor, and the air column cannot play a good cushioning role.

[0005] Therefore, how to make the inverted V-shaped cover of the cushioning air column bag level with the edge of the TV corner area to improve the wrapping effect of the inverted V-shaped cover on the entire corner area has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] In response to the defects in the existing technology, the present invention provides an inverted V-shaped corner protection cushioning air column bag, which realizes the leveling of the inverted V-shaped cover and the edge of the TV, and improves the covering effect of the inverted V-shaped cover of the cushioning air column bag on the entire corner area.

[0007] To achieve the above-mentioned object, the present invention provides an inverted V-shaped corner protection cushioning air column bag, comprising a first inner wall and a second inner wall arranged opposite to each other; the tops of the first inner wall and the second inner wall intersect to form an outwardly protruding inverted V-shaped cover; the connecting edges of the first inner wall and the second inner wall are connected by a longitudinal heat seal line on the inner wall to form a closed protective area for abutting against the corners of a television;

[0008] The first inner wall and the second inner wall are connected at positions close to the inner wall longitudinal heat sealing line through an inner wall heat sealing point, and the inner wall heat sealing point is located below the top of the corresponding cover of the inverted V-shaped cover.

[0009] Preferably, the inner wall longitudinal heat sealing line extends upward and is connected to the top of the inverted V-shaped cover.

[0010] Preferably, the inner wall heat sealing point is flush or nearly flush with the top of the inverted V-shaped cover at one end away from the inner wall longitudinal heat sealing line.

[0011] Preferably, the inner wall heat sealing point is set as an inner wall horizontal heat sealing line.

[0012] Preferably, the inner wall horizontal heat sealing line is perpendicular to the inner wall vertical heat sealing line.

[0013] Preferably, the inner wall transverse heat sealing line extends toward the inner wall longitudinal heat sealing line and is connected to the inner wall longitudinal heat sealing line.

[0014] Preferably, it further comprises a first outer wall and a second outer wall respectively located outside the first inner wall and the second inner wall, and a top side wall fixedly connected between the first outer wall and the second outer wall;

[0015] The first outer wall, the second outer wall and the top side wall, the first outer wall and the first inner wall, and the second outer wall and the second inner wall are all connected by bending nodes;

[0016] The connecting edges of the first outer wall, the first inner wall, the second inner wall, and the second outer wall are connected by a four-wall longitudinal heat seal line. The four-wall longitudinal heat seal line and the inner wall longitudinal heat seal line are colinear to form a lip seal line for sealing the gap between the first inner wall and the second inner wall, and the four-wall longitudinal heat seal line is located below the inner wall longitudinal heat seal line.

[0017] Preferably, with the lip seal line as the boundary, the first inner wall and the second inner wall extend in a direction away from the protection zone to form a buffer zone, and the buffer zone and the protection zone are respectively located on both sides of the lip seal line; the buffer zone includes a plurality of outer air columns for abutting against the inner wall of the carton, and the protection zone includes a plurality of inner air columns for abutting against the corners of the television.

[0018] Preferably, the included angle between the first outer wall, the second outer wall and the top side wall is 90 degrees.

[0019] Preferably, the first inner wall and the second inner wall both include a tapered portion and an extended portion; the upper ends of the tapered portions of the two intersect to form an inverted V-shaped cover protruding outward, and the extended portions of the two extend parallel to both sides of the cover opening of the inverted V-shaped cover to connect with the first outer wall and the second outer wall.

[0020] The present invention has the following beneficial effects:

[0021] The above technical solution shows that the inverted V-shaped corner protection cushioning air column bag provided by the present invention includes a first inner wall and a second inner wall arranged opposite to each other, wherein the top of the first inner wall intersects with the top of the second inner wall to form an inverted V-shaped cover. The connecting edges of the first inner wall and the second inner wall are connected by an inner wall longitudinal heat seal line, and the parts of the first inner wall and the second inner wall near the inner wall longitudinal heat seal line are also connected by an inner wall heat seal point, and the inner wall heat seal point is located below the top of the corresponding cover of the inverted V-shaped cover, so that the edges of the corner area of the TV are aligned with the inverted V-shaped cover air column, so that the two oblique sides of the inverted V-shaped cover formed by the intersection of the first inner wall and the second inner wall can be closely attached to the corresponding edges, and the wrapping effect is better.

[0022] During packaging, the inverted V-shaped cover is placed over the corners of the television. The edges of the TV's corners near the corners are held in place by the heat-sealed points on the inner wall, allowing the inverted V-shaped cover to align with the edges of the TV's corners. This allows the entire edge of the corner to closely align with the air columns of the two oblique edges of the inverted V-shaped cover. In other words, the inverted V-shaped corner protection air column bag provided by the present invention can achieve an excellent covering effect on the entire corner area, ensuring a close fit with the air columns of the inverted V-shaped cover, resulting in a superior cushioning effect.

DETAILED DESCRIPTION

[0031] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the following examples of the present application are further described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other unless they conflict.

[0032] See also Figures 1 to 5 , Figure 1 This is the appearance of the inverted V-shaped corner cushioning air column bag; Figure 2 for Figure 1 Schematic diagram of the inverted V-shaped corner cushioning air column bag hiding the first outer wall; Figure 3 Schematic diagram of the connection between the first inner wall and the second inner wall of the inverted V-shaped corner cushion air column bag; Figure 4 A schematic diagram of the assembly of the first and second inner walls of the inverted V-shaped corner cushioning air column bag with the corner area of the TV set; Figure 5 This is a schematic diagram of the installation of the inverted V-shaped corner cushioning air column bag.

[0033] The present invention discloses an inverted V-shaped corner protection cushioning air column bag, comprising a first inner wall 2 and a second inner wall 3 arranged opposite to each other, wherein the top ends of the first inner wall 2 and the second inner wall 3 intersect to form an outwardly protruding inverted V-shaped cover 6, and the outward in the text refers to the outward direction of the space between the first inner wall 2 and the second inner wall 3. The connecting edges of the first inner wall 2 and the second inner wall 3 are connected by an inner wall longitudinal heat sealing line 7 to form a closed protective area for resisting against the corners of a television. The special structure of the inverted V-shaped cover 6 makes the width of the inverted V-shaped cover 6 gradually narrower toward the corners of the television, providing conditions for the inverted V-shaped cover 6 to be close to the corners of the television, so that the inverted V-shaped cover 6 can cover the corners.

[0034] Because the width of the inverted V-shaped cover 6 gradually widens as it moves away from the corner, the top 6a of the inverted V-shaped cover 6 gradually becomes lower as it moves away from the corner. In other words, the top 6a of the inverted V-shaped cover 6 has a downward inclination as it moves away from the corner, which prevents it from being flush with the edge of the TV's corner. Consequently, the areas away from the corner where the two oblique sides of the inverted V-shaped cover 6 lie unable to closely adhere to the corresponding edges, resulting in poor overall wrapping of the corner, and the air column failing to provide a good cushioning effect.

[0035] The inverted V-shaped corner cushioning air column bag provided by the present invention optimizes the connection structure between the first inner wall 2 and the second inner wall 3, so that the inverted V-shaped cover 6 formed between the first inner wall 2 and the second inner wall 3 can be relatively leveled with the edge of the corner area 14 of the television set, so that the air columns of the two oblique sides of the inverted V-shaped cover 6 can closely contact the entire edge of the corner area. Specifically, the first inner wall 2 and the second inner wall 3 near the inner wall longitudinal heat seal line 7 are further connected by an inner wall heat seal point 8, which is located below the corresponding cover top 6a of the inverted V-shaped cover 6.

[0036] During packaging, the inverted V-shaped cover 6 is placed on the corner area 14 of the TV, and the edges of the TV corner area adjacent to the corner are limited by the inner wall heat sealing point 8, so that the inverted V-shaped cover 6 can be relatively leveled with the edges of the TV corner area. Figure 4 In this way, the air columns of the two oblique sides of the inverted V-shaped cover 6 can closely wrap the entire edge of the corner area, thereby achieving a better overall wrapping effect and a better buffering effect.

[0037] Preferably, when the inner wall heat sealing point 8 is flush or nearly flush with the cover top 6a of the inverted V-shaped cover 6 at one end away from the inner wall longitudinal heat sealing line 7, the leveling effect is best and the overall wrapping effect of the corner area of the TV is best.

[0038] To sum up, the inverted V-shaped corner protection cushioning air column bag provided by the present invention optimizes the connection structure between the first inner wall 2 and the second inner wall 3, so that the inverted V-shaped cover 6 formed between the first inner wall 2 and the second inner wall 3 can be relatively leveled with the edges of the corner area of the TV, so that the air columns of the two oblique sides of the inverted V-shaped cover 6 can be tightly attached to the entire edge of the corner area, thereby improving the covering effect of the corner protection cushioning air column bag on the entire corner area and achieving a good cushioning effect.

[0039] In another embodiment, the inner wall heat seal point 8 can be configured as a horizontal inner wall heat seal line. More preferably, to facilitate alignment with the corner edge of the television, the horizontal inner wall heat seal line extends toward the inner wall longitudinal heat seal line 7 and connects to the inner wall longitudinal heat seal line 7, being configured perpendicular to the inner wall longitudinal heat seal line 7. Of course, the inner wall heat seal point 8 is not limited to point or line heat seals; other heat seal structures are also acceptable.

[0040] In another embodiment, the inverted V-shaped buffer air column bag provided by the present invention also includes a first outer wall 1 and a second outer wall 4 respectively located on the outside of the first inner wall 2 and the second inner wall 3, and a top side wall 5 fixedly connected between the first outer wall 1 and the second outer wall 4. The first outer wall 1 and the second outer wall 4 and the top side wall 5, the first outer wall 1 and the first inner wall 2, and the second outer wall 4 and the second inner wall 3 are all bent and connected through bending nodes 10. The connecting edges on one side of the first outer wall 1, the first inner wall 2, the second inner wall 3, and the second outer wall 4 are connected by a longitudinal heat sealing line 9 on the four walls, providing conditions for forming a closed protective space. During packaging, the first outer wall 1, the second outer wall 4 and the top side wall 5 are directly attached to the inner wall of the carton, and the first inner wall 2 and the second inner wall 3 are both attached to the angular areas of the TV, so that the entire air column structure can effectively play a buffering and shock-absorbing role.

[0041] The four-wall longitudinal heat seal line 9 is collinear with the inner wall longitudinal heat seal line 7 and is located below the inner wall longitudinal heat seal line 7. The inner wall longitudinal heat seal line 7 extends upward to connect to the cover top 6a of the inverted V-shaped cover 6. The four-wall longitudinal heat seal line 9 and the inner wall longitudinal heat seal line 7 are collinear to form a lip seal line, which seals the gap between the first inner wall 2 and the second inner wall 3, forming a closed protective space.

[0042] In the present invention, the inner wall longitudinal heat seal line 7 is used to seal the first inner wall 2 and the second inner wall 3 separately, thereby preventing the first outer wall 1 and the second outer wall 4 from warping and deformation due to the excessive length of the four-wall longitudinal heat seal line 9. This further prevents the top side wall 5 from warping and deformation due to the entanglement between the first outer wall 1 and the second outer wall 4. In this way, the flatness of the outer surface of the top side wall 5 can be guaranteed, so that the top side wall 5 can be closely attached to the inner wall of the carton, thereby further improving the cushioning effect.

[0043] In the present invention, in order to further ensure the flatness of the outer surface of the top side wall 5, the angle between the first outer wall 1, the second outer wall 4 and the top side wall is 90 degrees, so that the top side wall can better fit tightly against the inner wall of the paper box.

[0044] like Figure 4 As shown, with the lip seal line as the boundary, the first inner wall 2 and the second inner wall 3 extend away from the protection zone to form a buffer zone 12, and the buffer zone and the protection zone are respectively located on both sides of the lip seal line. In other words, Figure 4 The lip seal line is used as the boundary, the left side of the lip seal line is the buffer zone 12, and the right side is the protection zone. The buffer zone 12 includes a number of outer air columns for contacting the inner wall 13 of the carton, and the protection zone includes a number of inner air columns for contacting the corner area 14 of the TV.

[0045] During packaging, the first outer wall 1, the second outer wall 4, and the top side wall 5 directly contact the carton inner wall 13 to provide the primary cushioning function, while the buffer zone 12 formed by the extension of the first inner wall 2 and the second inner wall 3 provides an auxiliary cushioning function. In this way, the outer and inner walls work together to provide cushioning, thereby enhancing the cushioning effect.

[0046] In another embodiment, the first inner wall 2 and the second inner wall 3 both include a tapered portion and an extended portion. Figure 2 As shown, the upper ends of the first inner wall tapered portion 2a and the second inner wall tapered portion 3a intersect to form an inverted V-shaped cover 6. The first inner wall extension portion 2b and the second inner wall extension portion 3b extend parallel to the sides of the cover opening of the inverted V-shaped cover 6 to connect with the first outer wall 1 and the second outer wall 4. The extensions increase the depth of the groove between the first inner wall 2 and the second inner wall 3, thereby improving the cushioning and shock absorption effect.

[0047] An inflation channel 11 is provided on the end of the second inner wall extension 3b, away from the inverted V-shaped cover 6. This channel inflates the entire airbag structure. Positioning the channel 11 inside the second inner wall 3 conceals the channel to a certain extent, preventing the wrinkles from being exposed and enhancing the overall aesthetics of the airbag. Alternatively, the channel 11 could be positioned on the end of the first inner wall extension 2b, away from the inverted V-shaped cover 6, still enhancing the aesthetics of the airbag.

[0048] The above is a detailed introduction to the inverted V-shaped corner guard cushioning air column bag provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. 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, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
