Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a novel three-dimensional packaging bag. Background Art

[0002] Packaging bags have been widely used in people's daily lives to package various items. Packaging bags are usually made of flexible materials. Compared with other rigid packaging containers, they are low-cost and have a wider range of applications. Packaging bags usually include sealed packaging bags and breathable packaging bags, which are used to hold different items respectively.

[0003] Traditionally used packaging bags usually use two pieces of plastic film at the front and back, which are heat-pressed and sealed on three sides, leaving an opening on the remaining side. The items are placed into the packaging bag through the opening, and then the side with the opening is heat-pressed and sealed to complete the packaging.

[0004] However, since the packaging bag itself is made of flexible material, when the items in the packaging bag do not have a fixed shape, the packaging bag is easy to deform, which is not only not conducive to the overall aesthetic effect of the packaging bag, but also not conducive to the safe storage of the items in the packaging bag. When placing, due to the flexibility of the packaging bag itself, the packaging bag is difficult to place stably, and the display is relatively limited, resulting in the packaging bag being difficult to meet the use requirements in production and sales. In particular, when pouring out the items contained in the packaging bag, it is inconvenient to hold and the items in the packaging bag are easy to spill, and the amount of pouring is difficult to control, thus causing waste.

[0005] In the current prior art, a packaging bag with a support structure disclosed in a Chinese patent with authorization announcement number CN202295638U supports the packaging bag by arranging a support rod in the packaging bag.

[0006] Another example is a packaging bag with a supporting structure disclosed in a Chinese patent with authorization announcement number CN216581878U, which supports the packaging bag by extending a supporting sheet at the bottom of the packaging bag.

[0007] However, the above technical solution still has at least the following defects: the structure of the packaging bag is relatively complex, the production cost is high, and the use of the packaging bag must follow certain operations to achieve the desired effect. The operation is cumbersome, which greatly reduces the flexibility and adaptability of the use of the packaging bag. The stability of the spatial three-dimensional effect is poor, making it difficult to meet the use needs in daily production and life, and has great limitations in use. Utility Model Content

[0035] The main bag sheet 1 includes a support portion 11 and a sealing portion 12. The sealing portions 12 are symmetrically formed at the edges of both sides of the main bag sheet 1. The two sealing portions 12 are correspondingly connected to form a main rib 13 for axially supporting the packaging bag. The support portion 11 is used to limit the deformation of the main bag sheet 1 along the axial direction of the bag body;

[0036] The main ribs 13 are much thicker than the main bag sheet 1, and at least one side edge of the main ribs 13 is formed with an axial opening angle 1301 along the axial direction of the bag body for supporting the main bag sheet 1;

[0038] The secondary ribs 22 have a thickness much greater than that of the sealing bag sheet 2 , and a radial opening angle 2201 for supporting the sealing bag sheet 2 is formed on the side edge of at least one secondary rib 22 along the radial direction of the bag body.

[0039] like Figure 1-5 As shown, in these embodiments, preferably, the axial opening angle 1301 is formed on both side edges of the main rib 13, and the radial opening angle 2201 is formed on both side edges of the secondary rib 22, and the opening angles of the axial opening angle 1301 and the radial opening angle 2201 are any angles, and further preferably, the opening angles are 30-120 degrees.

[0040] Furthermore, in the utility model, the material of the packaging bag can be a nylon filter material or a corn fiber filter material, and the filter material can also effectively meet the use requirements of the breathable packaging bag.

[0041] It should be understood that the packaging bag in the current prior art mainly includes a bag body and two ends of the packaging bag. The direction of the bag body is mainly determined by the use requirements and the production process, such as vertical placement, flat use, and three-dimensional use. Based on this, the axial direction of the bag body and the radial direction of the bag body in the utility model refer to the axial direction and radial direction of the packaging bag itself. Specifically, the direction along the bag body of the packaging bag is the axial direction of the bag body, and the direction perpendicular to the axial direction of the bag body is the radial direction of the bag body. For the sake of ease of understanding, specific examples are given. For example, when the packaging bag is placed vertically for use (that is, the packaging bag is in a three-dimensional shape), the axial direction is the vertical direction, and the radial direction is the horizontal direction.

[0042] Furthermore, in the utility model, the corresponding connection of the two sealing parts 12 includes but is not limited to bonding, adhesion, melting, etc., that is, the corresponding connection refers to fixing the corresponding positions of the sealing parts 12 together. Similarly, the corresponding connection between the reinforcement part 21 and the main bag sheet 1 is the same as the above understanding.

[0043] Through the cooperation of the supporting part 11, the sealing part 12 and the reinforcing part 21 on the main bag sheet 1, the three-dimensional spatial effect of the packaging bag can be effectively guaranteed, and through the coordinated action of the main ribs 13 and the secondary ribs 22, the overall rigidity of the packaging bag is guaranteed, the three-dimensional stability of the packaging bag is effectively improved, and the deformation of the packaging bag along the axial direction and the radial direction of the bag body is limited, making it difficult to deform easily, so that it can be placed stably, and through the cooperation of at least one axial opening angle 1301 and at least one radial opening angle 2201, the stability and reliability of the use of the packaging bag are further improved, the structure is simpler and more stable (the triangle support stability of the open angle is higher), and the stability of the packaging bag itself is greatly improved, which is not only beneficial to improving the overall aesthetic effect of the packaging bag, but also beneficial to the safe storage of items in the packaging bag, and can also effectively meet the needs of production, sales and use, greatly improving the flexibility and adaptability of use, and the three-dimensional packaging bag is more stable when held, and is more convenient for holding or pouring items, which greatly improves the practicality of use.

[0044] In some embodiments of the novel three-dimensional packaging bag, the main bag sheet 1 is connected in a closed loop through the sealing portion 12 to form a bag body, the bag body has two openings, and the bag body is any one of a polyhedron and a rotating body.

[0045] In these embodiments, the polyhedron includes but is not limited to a prism and a truncated cone, and the solid of revolution includes but is not limited to a cylinder, a truncated cone, and a sphere, wherein Figure 6 As shown in FIG. 1 , the packaging bag is a prismatic bag.

[0047] In some embodiments of the novel three-dimensional packaging bag, the support portion 11 is formed on the main bag sheet 1 along the axial direction of the bag body, and the reinforcement portion 21 is used to connect the sealing bag sheet 2 to the bag body opening and to limit the deformation of the sealing bag sheet 2 along the radial direction of the bag body.

[0048] In these embodiments, the reinforcing portion 21 not only facilitates accurate connection of the sealed bag sheet 2 , but also helps to improve the stability of the sealed bag sheet 2 .

[0050] In these embodiments, the support portion 11 is integrally formed on the main bag sheet 1 . The uniform arrangement of at least three support portions 11 not only effectively improves the stability of the bag body, but also facilitates the stability of the sealing bag sheet 2 and the main bag sheet 1 .

[0051] Furthermore, when the support portion 11 is located at the corners of the bag body and the bag body is a polygonal column, it not only ensures the three-dimensional effect of the packaging bag and increases the support effect of the packaging bag, but also ensures the grip of the packaging bag, making the packaging bag safer and more reliable to use.

Similarly, the reinforcing effect of the reinforcing portion 21 on the sealing bag sheet 2 is increased, and the supporting portion 11 and the reinforcing portion 21 are connected. Through the synergistic effect of the supporting portion 11 and the reinforcing portion 21, the spatial stability of the packaging bag can be effectively improved, which is beneficial to increasing the service life of the packaging bag.

[0054] Furthermore, the support portion 11 and the main bag sheet 1 as well as the reinforcement portion 21 and the sealing bag sheet 2 are all smoothly transitioned, thereby ensuring the smoothness of the main bag sheet 1 and the sealing bag sheet 2 .

[0055] In some embodiments of the novel three-dimensional packaging bag, the support portion 11 is any one of a strip, a circle, an ellipse, and a polygon.

[0056] In these embodiments, for bags of different shapes and specifications, support portions 11 of different shapes are preferred, which can better adapt to the use of the packaging bag.

[0057] In some implementations of the novel three-dimensional packaging bag, the reinforcing portion 21 is matched with the opening of the bag body, and the reinforcing portion 21 is any one of closed loop shapes.

[0058] In these embodiments, by adapting the reinforcing portion 21 to the bag body opening, it is possible to better adapt to the support and coordination of different bag bodies, thereby ensuring the stability and reliability of packaging bags of different shapes.

[0059] In some embodiments of the novel three-dimensional packaging bag, the main bag sheet 1 further includes a reinforcing portion 14. The reinforcing portion 14 is formed in the middle of the main bag sheet 1. The reinforcing portion 14 is used to limit the deformation of the bag body.

[0060] In some embodiments of the novel three-dimensional packaging bag, the reinforcing portion 14 is in the shape of a strip surrounding the bag body, and the thickness of the reinforcing portion 14 is not less than the thickness of the main bag sheet 1 .

[0061] In these embodiments, by providing the reinforcement portion 14 on the bag body, not only can the deformation of the packaging bag along the radial direction and the axial direction of the bag body be further limited to improve the stability of the packaging bag, but also the aesthetic effect of the packaging bag can be improved, making it more convenient and flexible to use.

[0062] In some embodiments of the novel three-dimensional packaging bag, the sealing bag sheet 2 further includes an opening and closing portion 23, which is formed on one of the sealing bag sheets 2 and is used to open or close the packaging bag.

[0063] In these embodiments, the packaging bag can be flexibly opened or closed by the opening and closing portion 23, which is convenient for the filling and pouring of items. The closing form of the opening and closing portion 23 is fully closed, semi-closed, or open, such as a twist-off cover, a flip-up cover, or an open cover.

[0064] Furthermore, the opening and closing portion 23 includes an opening and closing port and an opening and closing cover. The opening and closing port is fixedly connected to one of the sealing bag sheets 2, and the opening and closing cover is detachably mounted on the opening and closing port. Preferably, the opening and closing cover can be threadedly mounted on the opening and closing port.

[0065] When the utility model is used, the cooperation of the supporting part 11, the reinforcing part 21 and the strengthening part 14 can effectively ensure the spatial three-dimensional effect of the packaging bag, and the cooperation of the main ribs 13, the secondary ribs 22, the axial opening angle 1301 and the radial opening angle 2201 can achieve the spatial stability of the packaging bag when containing articles, which is not only beneficial to improving the overall aesthetic effect of the packaging bag, but also beneficial to the safe storage of the articles in the packaging bag, effectively meeting the needs of production, sales and use, and having a better grip, which is convenient for the filling and pouring of articles.

[0066] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
