Technical Field
[0001] The utility model relates to the technical field of packaging, in particular to a packaging bag. Background Art
[0002] With the development of social economy, packaging bags have become an indispensable and common tool in today's society. From the packaging of small items for daily shopping to the transportation of bulk goods in express logistics, the application scenarios of packaging bags are extremely wide, and people's requirements for packaging bags are getting higher and higher.
[0003] Packaging bags refer to bags used to package various items, mainly for convenient transportation and storage during production and circulation. They are widely used in daily life and industrial production, and come in a variety of types and materials; such as non-woven bags, paper bags, plastic bags, etc.
[0004] When packaging articles, such as gift boxes, packaging bags are usually used in the prior art. However, in order to cover the bag opening, the bag opening is usually closed by setting a flap. However, after the bag opening is closed, the bag opening of the packaging bag in the prior art is usually connected to the side wall of the packaging bag. On the one hand, the wrapping performance of the articles placed in the packaging bag is poor, and on the other hand, the flap protrudes from the bag opening, which also reduces the aesthetics of the packaging bag. Utility Model Content
[0005] The utility model aims to solve the problems that the packaging bag in the prior art has poor wrapping performance for the articles placed in the packaging bag and the flap protrudes from the bag opening, which reduces the aesthetics of the packaging bag.
[0006] In order to solve the above-mentioned problems, the utility model provides a packaging bag, including a bag body, the bag body including a pair of front faces arranged opposite to each other in the thickness direction of the bag body, a pair of side faces arranged opposite to each other in the width direction of the bag body, and a bottom surface arranged at the bottom of the bag body along the height direction of the bag body, and the pair of front faces and the pair of side faces are surrounded at the top of the bag body to form a bag opening.
[0007] Among them, the top of one of the pair of side walls opposite to each other around the bag opening is provided with a flap that can be flipped around the top edge of one side wall, and the other is provided with a first overlap edge extending along the top edge of the other side wall and toward the bag opening, and; the flap is flipped relative to the top edge of one side wall to switch between a closed state closing the bag opening and an open state exposing the bag opening, and the flap in the closed state is away from the free end of one side wall and overlapped and fixed with the opposite surface of the first overlap edge.
[0008] By adopting the above technical solution, during the use of the packaging bag, the flap is flipped to the state of opening the bag, and then the items are placed into the packaging bag from the bag opening; the flap is then flipped so that the flap closes the bag opening, and the free end of the flap is overlapped and fixed with the opposite surface of the first overlapped edge, so that when the flap is in the closed state, the flap and the bag opening are fixed to each other, avoiding the risk of the items slipping out or falling out of the bag opening during the bumping process. In addition, after the flap and the bag opening are fixed to each other, the items placed in the bag body are limited, which improves the bag body's wrapping of the items and makes it less likely to shake.
[0009] Furthermore, when the free end of the flap in the closed state is overlapped and fixed with the relative surface of the first overlap edge, since the first overlap edge extends toward the bag opening, the flap is located inside the bag opening in the closed state, and the flap can directly contact the article; on the one hand, the flap and the bag body cooperate to better wrap the article, making it less likely for the article to shake; on the other hand, the flap will not protrude from the bag opening, thereby having no effect on the appearance of the bag body, thereby improving the aesthetics of the packaging bag.
[0010] Furthermore, in one embodiment, the flap is formed integrally with the top of one side wall to enhance the connection strength between the flap and the bag body, thereby making the packaging bag more durable.
[0011] Alternatively, in another embodiment, the top edge of a side wall has a second overlap extending toward the bag opening, and the flap is fixed to the second overlap. When the packaging bag is in use, for example, for packaging fruits and vegetables, the items in the bag may need to be ventilated. Therefore, the flap can be removed from the second overlap, so that the bag opening is in an open state, achieving a ventilation effect. Therefore, this packaging bag also has the advantage of high applicability.
[0012] Further, in one embodiment, a pair of side walls is a pair of front faces, and the flip cover can be flipped around the width direction.
[0013] With the above technical solution, since the width of the front side is relatively large, the flap is arranged on the front side, thereby further strengthening the connection strength between the flap and the bag opening.
[0014] Furthermore, in one embodiment, the top of each side is also provided with a third overlapping edge along its top edge and extending toward the bag opening; wherein the two side edges of the flap in a closed state are overlapped and fixed to the relative surfaces of the third overlapping edge on the corresponding side.
[0015] By adopting the above technical solution, when the flap is in a closed state, it is fixedly overlapped with the surfaces of the first overlapping edge and the third overlapping edge respectively. On the one hand, the position of a pair of front faces and a pair of side faces can be limited by the flap, so that the bag body is not easily deformed; on the other hand, after the flap and the bag opening are fixed to each other, the connection strength between the flap and the bag opening is higher, and the package placed in the bag body is more reliable, further improving the wrapping property of the bag body for the items.
[0016] Further, in one embodiment, the third overlapping edge of each side surface includes a plurality of overlapping edge segments sequentially spaced apart along the extension direction of the side surface.
[0017] By adopting the above technical solution, by setting multiple overlapping sections, when multiple items are stacked in the thickness direction and placed in a three-dimensional bag, when one item needs to be taken out, the flap can be separated from the overlapping section closest to the free end of the flap, so that the flap can be flipped to an open state, so as to take out the items in the bag body without affecting the storage of other items, thereby making this packaging bag more applicable.
[0018] Furthermore, in one embodiment, the first overlapping edge is a first lining strip extending along the width direction, one side of the first lining strip is fixed to the inner side wall of the top edge of a corresponding one of the pair of front faces, and the other side extends toward the bag opening; the second overlapping edge is a second lining strip extending along the width direction, the second lining strip is integrally formed with the top of the other front face of the pair of front faces, and the free end extends through the top edge of the other front face toward the bag opening.
[0019] The third overlap includes a plurality of third lining strips extending in the thickness direction and arranged at intervals from each other. One side of each third lining strip is fixed to the inner side wall of the top edge of a corresponding side surface, and the other side extends toward the bag opening.
[0020] By adopting the above technical solution, when the free end of the flap rotates around the width direction and the flap is in a closed state, the flap is fixedly overlapped with the first lining strip and the third lining strip and the opposite side thereof, respectively, thereby achieving limitation of the items (such as gift boxes) placed inside the bag body in the thickness direction, width direction and height direction, avoiding the risk of items slipping or falling out of the bag mouth during bumps, and improving the wrapping of the bag body for the items, making it less likely to shake.
[0021] Furthermore, in one embodiment, an adhesive is provided on the outer surface of the first inner lining strip, and the free end of the flip cover is directly fixedly overlapped on the outer surface of the first inner lining strip through the adhesive.
[0022] By adopting the above technical solution, the purpose of limiting the position of the articles placed inside the bag body in the thickness direction and the height direction is achieved.
[0023] Furthermore, in one embodiment, auxiliary adhesives are provided at the periphery of the flap and / or at the locations of the third inner lining strip that are opposite to each other, and the flap is fixedly overlapped on the corresponding surface of the third inner lining strip through the auxiliary adhesives.
[0024] By adopting the above technical solution, when the flap is in a closed state, the flap can be fixedly overlapped with the third inner lining strip through the auxiliary adhesive part, so that the flap is not easily detached from the third inner lining strip during transportation of the bag, further enhancing the wrapping ability of the bag for articles.

[0036] Packaging bags are bags used to pack various items, making it easy to transport and store goods during production and circulation. They are widely used in daily life and industrial production.
[0037] In particular, paper bag packaging is a very common packaging method, which is commonly used for high-end packaging such as clothing, shoe boxes, and gift boxes. However, in the prior art, when packaging articles, in order to cover the bag opening, the bag opening is generally closed by setting a flap, but the bag opening of the prior art packaging bag is generally connected to the side wall of the packaging bag after the bag opening is closed, which, on the one hand, has poor wrapping performance for the articles placed in the packaging bag, and on the other hand, the flap protrudes from the bag opening, which also reduces the aesthetics of the packaging bag.
[0038] In order to solve the above problems, the utility model provides a packaging bag, wherein the top of one of the pair of side walls facing each other around the bag opening is provided with a flap that can be turned around the top edge of one side wall, and the other is provided with a first overlap extending along the top edge of the other side wall and toward the bag opening. In the process of using the packaging bag, the free end of the flap is overlapped and fixed with the opposite surface of the first overlap, thereby avoiding the risk of the item slipping out or falling out of the bag opening during the bumping process. In addition, after the flap and the bag opening are fixed to each other, the items placed in the bag body are limited, thereby improving the wrapping of the bag body for the items and preventing them from shaking.
[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0040] like Figure 1 and Figure 2 As shown, the utility model provides a packaging bag 1, including a bag body 10, the bag body 10 includes a pair of front faces 100 arranged oppositely in the thickness direction L of the bag body 10, a pair of side faces 101 arranged oppositely in the width direction W of the bag body 10, and a bottom face 102 arranged at the bottom of the bag body 10 along the height direction H of the bag body 10 (see Figure 4 ), and a pair of front faces 100 and a pair of side faces 101 surround the top of the bag body 10 to form a bag opening 103.
[0041] Specifically, a flap 104 that can be turned around the top edge of one side wall is provided at the top of one side wall of a pair of side walls that are opposite to each other around the bag opening 103, and a first overlap 105 that extends along the top edge of the other side wall and toward the bag opening 103 is provided at the other side wall, and the flap 104 can be turned relative to the top edge of one side wall to switch between a closed state that closes the bag opening 103 and an open state that exposes the bag opening 103, and the free end of the flap 104 in the closed state away from one side wall is overlapped and fixed with the opposite surface of the first overlap 105. It should be understood that a pair of front faces 100 and a pair of side faces 101 surround and form a bag body 10, and a cavity for placing articles is formed inside the bag body 10, and in the height direction H, the bag opening 103 is located at the top of the bag body 10; and the surrounding side walls of the bag opening 103 are inner side walls in the height direction H, where the pair of front faces 100 and the pair of side faces 101 are located at the top.
[0042] More specifically, during the use of the packaging bag 1, the flip cover 104 is turned over to open the bag opening 103 ( Figure 1 The article is then placed into the packaging bag 1 from the bag opening 103; the flap 104 is then turned over so that the flap 104 closes the bag opening 103 ( Figure 5 The flap 104 is fixed to the bag opening 103 when the flap 104 is in the closed state, thereby preventing the risk of the item slipping out or falling out of the bag opening 103 during bumping. In addition, after the flap 104 and the bag opening 103 are fixed to each other, the items placed in the bag body 10 are limited, thereby improving the bag body 10's wrapping of the items and preventing them from shaking.
[0043] Furthermore, in the closed state, when the free end of the flap 104 is overlapped and fixed with the relative surface of the first overlap 105, since the first overlap 105 extends toward the bag opening 103, the flap 104 is located inside the bag opening 103 in the closed state, and the flap 104 can directly contact the articles; on the one hand, the flap 104 cooperates with the bag body 10 to better wrap the articles, making it less likely for the articles to shake; on the other hand, the flap 104 does not protrude from the bag opening 103, thereby having no effect on the appearance of the bag body 10, thereby improving the aesthetics of the packaging bag 1.
[0044] The connection between the flip cover 104 and a side wall of the bag opening 103 is further explained below.
[0045] Optionally, in a feasible implementation, as Figure 2 As shown, the flip cover 104 is formed integrally with the top of one side wall of the bag opening 103 , thereby improving the connection strength between the flip cover 104 and the bag body 10 , making the packaging bag 1 more durable.
[0046] Alternatively, in another embodiment, Figure 1 As shown, the top edge of one side wall of the bag opening 103 has a second overlap 106 extending toward the bag opening 103, and the corresponding side edge of the flap 104 is fixed on the second overlap 106; when the packaging bag 1 is in use, for example, when it is used to pack fruits and vegetables, since the items in the bag may need to be ventilated, the flap 104 can be removed from the second overlap 106, so that the bag opening 103 is in an open state, achieving the effect of ventilation and air permeability, so that this packaging bag 1 also has the advantage of high applicability.
[0047] Specifically, after the flap 104 is removed from the second overlap 106 , it can be stored separately without having to be placed in the bag body 10 or connected to a side wall of the bag body 10 , such as the front side 100 or the side side 101 , thereby ensuring the aesthetics of the packaging bag 1 .
[0048] The specific configuration of the flip cover 104 is further explained below.
[0049] In one embodiment, Figure 1-Figure 3 As shown, a pair of side walls for setting the bag opening 103 are a pair of front faces 100, a flap 104 is set on the top of one of the pair of front faces 100, a first overlap 105 is set on the top of the other front face 100 and extends toward the bag opening 103, and the flap 104 can be flipped around the width direction W. Since the actual connection area of the front face 100 is larger, the flap 104 is set on the front face 100, which further strengthens the connection strength between the flap 104 and the bag opening 103.
[0050] In another embodiment, a pair of side walls of the bag opening 103 can also be set as a pair of side surfaces 101, the flap 104 is set on the top of one of the pair of side surfaces 101, and the first overlap 105 is set on the top of the other side surface 101 and extends toward the bag opening 103.
[0051] Optionally, in a feasible embodiment, when the flap 104 is fixedly connected to the top of the front side 100, a third overlap 107 is also provided at the top of each side 101, and the third overlap 107 is located at the top edge of the side 101 and extends toward the bag opening 103; wherein, in the width direction W, the two side edges of the flap 104 in a closed state are respectively overlapped and fixed to the relative surfaces of the third overlap 107 on the corresponding side.
[0052] Specifically, when the flap 104 is in a closed state, it is fixedly overlapped with the surfaces of the first overlapped edge 105 and the third overlapped edge 107 respectively. On the one hand, the flap 104 can be used to limit the positions of a pair of front faces 100 and a pair of side faces 101, thereby making it difficult for the bag body 10 to deform. On the other hand, after the flap 104 and the bag opening 103 are fixed to each other, the connection strength between the flap 104 and the bag opening 103 is higher, and the items placed in the bag body 10 can be wrapped more reliably, further improving the wrapping property of the bag body 10 for the items.
[0053] Optionally, in a feasible implementation, as Figure 1 As shown, the first overlap 105 and the second overlap 106 can be flipped around the width direction W, and the third overlap 107 can be flipped around the thickness direction L. When putting items into the bag body 10, the second overlap 106 is flipped around the width direction W, so that the flap 104 is in an open state relative to the bag opening 103. Then, the first overlap 105 is flipped around the width direction W and fits with the front side 100, and the third overlap 107 is flipped around the width direction W and fits with the side 101. Then, the items are gradually put into the bag body 10, and the first overlap 105 and the third overlap 107 will not affect the entry of the items into the bag body 10.
[0054] Furthermore, after the items are placed inside the bag body 10, the first overlap 105 is flipped around the width direction W and is perpendicular to the front side 100, and the third overlap 107 is flipped around the width direction W and is perpendicular to the side 101. Then, the second overlap 106 is flipped around the width direction W to drive the free end of the flap 104 to flip, so that the edge position of the free end of the flap 104 is overlapped and fixed with the first overlap 105 and the third overlap 107 toward one side of the flap 104, so that there is an overlapping area between the edge position of the free end of the flap 104 and the first overlap 105 and the third overlap 107, thereby making this packaging bag 1 also have the advantage of high sealing during use.
[0055] Optionally, in a feasible implementation, as Figure 5 As shown, when the first overlap 105 is flipped around the width direction W and is perpendicular to the front side 100, and the third overlap 107 is flipped around the width direction W and is perpendicular to the side 101, in the height direction H, the positions of the first overlap 105 and the third overlap 107 that are close to each other overlap each other, so that after the items are placed in the bag body 10, the limiting effect of the first overlap 105 and the third overlap 107 on the items is enhanced.
[0056] Optionally, in a feasible implementation, as Figure 3As shown, when the flap 104 is arranged on the top of one of the pair of front faces 100 and the side 101 is provided with a third overlap 107, the third overlap 107 of each side 101 includes a plurality of overlap segments 108 arranged in sequence and at intervals along the extension direction of the side 101. Thus, by providing a plurality of overlap segments 108, when a plurality of items are stacked along the thickness direction L and placed in the three-dimensional bag, when one item needs to be taken, the flap 104 and the overlap segment 108 closest to the free end of the flap 104 can be opened relative to each other along the thickness direction L, so as to take one item without affecting the storage of other items, thereby improving the applicability of the packaging bag 1.
[0057] It should be further understood that the bag body 10, the first overlap 105, the second overlap 106, the flap 104 and the third overlap 107 are all made of any one of paper, non-woven fabrics and plastics; for example, the bag body 10 is made of paper material.
[0058] The structure and setting method of each overlap are further explained below.
[0059] In one possible implementation, Figure 3 Figure 4 As shown, the first overlap 105 is set as a first lining strip extending along the width direction W, and one side of the first lining strip is fixed on the inner side wall of the top edge of one of the pair of front faces 100 corresponding to it, and the other side extends toward the bag opening 103; the second overlap 106 is set as a second lining strip extending along the width direction W, the second lining strip is integrally formed with the top of the other of the pair of front faces 100, and the free end extends through the top edge of the other front face 100 toward the bag opening 103; the third overlap 107 includes a plurality of third lining strips extending along the thickness direction L and arranged at intervals from each other, one side of each third lining strip is fixed on the inner side wall of the top edge of the corresponding side face 101, and the other side extends toward the bag opening 103.
[0060] Specifically, when the free end of the flap 104 rotates around the width direction W and the flap 104 is in a closed state, the flap 104 is fixedly overlapped with the first lining strip and the third lining strip on the opposite side thereof, respectively, thereby limiting the items (such as gift boxes) placed inside the bag body 10 in the thickness direction L, the width direction W and the height direction H, avoiding the risk of items slipping or falling out of the bag opening 103 during bumps, and improving the wrapping property of the bag body 10 for the items, making it less likely to shake.
[0061] Optionally, in a feasible implementation, as Figure 1As shown, an adhesive 109 is provided on the outer surface of the first lining strip, and the free end of the flap 104 is directly fixed and overlapped on the outer surface of the first lining strip through the adhesive 109, thereby achieving the purpose of limiting the items placed inside the bag body 10 in the thickness direction L and the height direction H.
[0062] Optionally, in another feasible embodiment, in order to further strengthen the strength of the flap 104, a second lining strip with a larger size is provided in the thickness direction L. At this time, an adhesive 109 is also provided on the outer surface of the first lining strip, and the second lining strip is fixedly overlapped on the outer surface of the first lining strip through the adhesive 109; when the flap 104 is in a closed state, the second lining strip can be used to further strengthen the connection strength between the flap 104 and the bag opening 103.
[0063] It should be understood that when the flap 104 is in a closed state, the distance between the free end of the flap 104 and the top edge of the bag opening 103 in the height direction H is 0.5 cm to 2 cm, thereby ensuring that the free end of the flap 104 does not protrude from the edge of the bag opening 103 in the height direction H, thereby further ensuring the aesthetics of the packaging bag 1. For example, the distance between the free end of the flap 104 and the top edge of the bag opening 103 can be 0.5 cm, 1 cm, 1.5 cm, etc., which is not limited in this embodiment.
[0064] Optionally, in a feasible implementation, as Figure 1 and Figure 2 As shown, auxiliary adhesives 110 are provided at the periphery of the flap 104 and / or the portions of the third liner strip facing each other, and the flap 104 is fixedly overlapped on the corresponding surface of the third liner strip by the auxiliary adhesives 110. When the flap 104 is in a closed state, both sides of the flap 104 in the width direction W can be fixedly overlapped with the third overlapped edge 107 by the auxiliary adhesives 110, so that the flap 104 and the third overlapped edge 107 are not easily separated, thereby ensuring the reliability of the packaging bag 1 during use.
[0065] It should be understood that the auxiliary adhesive 110 can be only provided on the periphery of the flap 104; or, the auxiliary adhesive 110 can also be provided on the side of the third lining strip opposite to the flap 104; or, the auxiliary adhesive 110 is provided on the periphery of the flap 104 and the surfaces of the third lining strip opposite to each other.
[0066] Furthermore, those skilled in the art should understand that the adhesive member 109 and the auxiliary adhesive member 110 may be double-sided tape, Velcro, etc., which is not limited in this embodiment.
[0067] Further, in one embodiment, Figure 4As shown, in order to facilitate the taking and transportation of the packaging bag 1 during use, the packaging bag 1 also includes a handle 20, and two handle fixing areas are arranged at a predetermined interval on the outer wall of the bag opening 103 along the width direction W, and the two ends of the handle 20 are fixedly connected to the respective corresponding handle 20 fixing areas. By setting the handle 20. It should be understood that the handle 20 can be arranged on one front face 100, or the handle 20 can be arranged on both front faces 100; similarly, the handle 20 can also be arranged on one side face 101, or the handle 20 can be arranged on both side faces 101. The predetermined interval between the two handle fixing areas can be 5cm, 10cm, 15cm, etc., which is not limited in this embodiment.
[0068] Furthermore, in one embodiment, the flap 104 is provided with two handles at intervals in the width direction W of the bag body 10. By providing the handles, when the flap 104 is opened from a closed state to an open state relative to the bag opening 103, the flap 104 can be separated from the first overlap 105 and the third overlap 107 by manually pulling the handles, thereby opening the bag opening 103.
[0069] In summary, the advantages of the packaging bag 1 are as follows: when the flap 104 is fixedly connected to the top of the front side 100, during the use of the packaging bag 1, the flap 104 is flipped to open the bag opening 103, and then the article is put into the packaging bag 1 from the bag opening 103; then the flap 104 is flipped so that the flap 104 closes the bag opening 103, and the free end of the flap 104 is overlapped and fixed to the opposite surfaces of the first overlap 105 and the third overlap 107 through the adhesive member 109 and the auxiliary adhesive member 110. , so that when the flip cover 104 is in the closed state, the flip cover 104 and the bag opening 103 are fixed to each other. On the one hand, the flip cover 104 can limit the position of the pair of front faces 100 and the pair of side faces 101, so that the bag body 10 is not easy to deform; on the other hand, after the flip cover 104 and the bag opening 103 are fixed to each other, the connection strength between the flip cover 104 and the bag opening 103 is higher, and the package placed in the bag body 10 is more reliable, further improving the bag body 10 The wrapping property of the article.
