Description

Technical Field

[0001] This utility model relates to the field of aseptic packaging bag technology, specifically to an aseptic multi-cavity packaging bag. Background Technology

[0002] Aseptic multi-cavity packaging bags are a new type of packaging material that helps extend the shelf life of food and beverage products, allowing them to be stored and transported at room temperature without refrigeration, thus reducing distribution costs. However, traditional multi-cavity packaging bags are prone to loosening at the interface between the material and the packaging material during material feeding, leading to material leakage.

[0003] To overcome the above-mentioned defects, existing technology (Chinese patent CN221115088U, published on 2024-06-11) provides a sterile multi-cavity edible probiotic packaging bag, comprising a bag body with four cavities. A separating seal is provided at the connection between each pair of adjacent cavities. The remaining periphery of each cavity, excluding the separating seal, is sealed to form a circumferential seal. The sealing strength of the separating seal is less than that of the circumferential seal. Each cavity has a filling outlet on its circumferential seal, communicating with the corresponding cavity. One cavity of the bag is for powdered probiotics, one cavity is for liquid food matrix, and the remaining two cavities are used to hold either powdered or liquid food, respectively. This design is reasonable, effectively holding probiotics while ensuring their activity during use.

[0004] The aforementioned mechanism uses a partitioned sealing edge to separate the internal cavity, thereby ensuring the activity of probiotics during use. Utility Model Content

[0005] The purpose of this invention is to provide a sterile multi-cavity packaging bag to solve the problem mentioned in the background art where the interface and material interface of traditional multi-cavity packaging bags are prone to loosening during material feeding, leading to material leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sterile multi-cavity packaging bag, comprising a packaging bag body, wherein inlets are evenly distributed at the bottom end of the packaging bag body, a first docking plate is installed at the bottom end of the inlet, and a second docking plate is attached to the bottom end of the first docking plate, and a docking interface is fixedly connected to the bottom end of the second docking plate; a insertion tube is fixedly connected to the top end of the second docking plate, and a docking mechanism for locking the first and second docking plates is provided on the outer side of the second docking plates, the docking mechanism comprising a threaded sleeve, and the threaded sleeve is threadedly connected to the outside of the docking interface, a limit frame is rotatably connected to the side of the threaded sleeve, and the limit frame is engaged with the outer side of the first and second docking plates; a sealing mechanism for preventing the insertion tube from shaking is provided inside the docking interface.

[0007] Furthermore, the outer side of the interface is provided with a threaded groove, and the threaded sleeve and the threaded groove are mutually adapted to each other.

[0008] Furthermore, torsion springs are wound around both the front and rear ends of the limiting frame, and the threaded sleeve and the limiting frame form an elastic structure through the torsion springs.

[0009] Furthermore, a limiting block is provided at the bottom of the first docking plate, and a limiting groove matching the limiting block is provided at the upper end of the inner side of the limiting frame. The cross-section of the limiting block is triangular.

[0010] Furthermore, the outer side of the threaded sleeve is provided with anti-slip layers at equal intervals, and the height of the anti-slip layers is equal to the height of the threaded sleeve.

[0011] Furthermore, the sealing mechanism includes an elastic airbag, which is engaged with the inside of the first docking plate. Two connecting tubes are respectively provided on the inner side of the elastic airbag, and a sealing layer is sleeved on the outer side of the insertion tube. The elastic airbag and the sealing layer are connected by the connecting tubes.

[0012] Furthermore, the outer side of the packaging bag body is provided with a wear-resistant layer, and the inner side of the packaging bag body is provided with an anti-static layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By abutting the first and second docking plates at the bottom of the feed inlet, the feed inlet and the docking interface are basically aligned in position. Then, the insertion tube inside the second docking plate is inserted into the feed inlet to achieve docking between the feed inlet and the docking interface. Next, by rotating the threaded sleeve, the threaded sleeve and the threaded groove are connected, causing the threaded sleeve to move towards the second docking plate. This moves the limiting frame outward and deflects its angle. When the inner side of the limiting frame moves above the first docking plate, the force applied to the limiting frame is removed, allowing the limiting frame to automatically reset and engage with the outer side of the first docking plate by the elastic force of the torsion spring. The limiting block at the top of the first docking plate engages with the limiting groove on the inner side of the limiting frame, thus enabling the limiting frame to stably engage and connect the first and second docking plates, effectively preventing loosening of the feed inlet and the docking interface after docking.

[0015] Furthermore, the cross-section of the limiting block is triangular, and the limiting block and the limiting groove engage with each other, so that the limiting frame will not deflect outward due to external force during use, increasing the stability of the feed inlet and the interface when they are engaged.

[0016] Furthermore, the outer side of the threaded sleeve is provided with an anti-slip layer. This layer increases friction when the threaded sleeve is rotated, making the rotation of the threaded sleeve more stable and effectively preventing it from slipping out of your hand during rotation.

[0017] 2. When the first and second docking plates are docked, the second docking plate applies a compressive force to the elastic airbag. At the same time, the limiting frame locks the first and second docking plates together, so that the compressive force on the elastic airbag remains unchanged. The gas inside the elastic airbag is then transported to the interior of the sealing layer through the connecting pipe. The sealing layer fills the gap between the insertion pipe and the feed port, thereby effectively preventing the insertion pipe from shaking due to gaps when docking with the feed port and increasing the stability during use.

[0018] Furthermore, by providing a wear-resistant layer on the outside of the packaging bag body, the wear resistance of the packaging bag body can be increased, preventing the packaging bag body from breaking due to friction, thereby effectively increasing the service life of the packaging bag body. In addition, an anti-static layer is provided inside the packaging bag body, so that even when the packaging bag body is rubbed by the outside, the inside of the packaging bag body will not stick together and cannot be separated, increasing its applicability during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The technical solution shown addresses the problem of material leakage caused by loosening at the interface between the aseptic multi-cavity packaging bag and the material interface during material introduction. The aseptic multi-cavity packaging bag discloses a docking mechanism, including a packaging bag body 1. Inlet ports 4 are evenly spaced at the bottom of the packaging bag body 1. A first docking plate 6 is installed at the bottom of the inlet ports 4, and a second docking plate 7 is attached to the bottom of the first docking plate 6. A docking interface 5 is fixedly connected to the bottom of the second docking plate 7. A insertion tube 11 is fixedly connected to the top of the second docking plate 7. A docking mechanism for locking the first and second docking plates 6 and 7 is provided on their outer sides. The docking mechanism includes a threaded sleeve 12, and the threaded sleeve 12 is threaded... The threaded sleeve 12 is connected to the outside of the interface 5. The side of the threaded sleeve 12 is rotatably connected to the limit frame 14, and the limit frame 14 is engaged with the outside of the first docking plate 6 and the second docking plate 7. The outside of the interface 5 is provided with a threaded groove 16, and the threaded sleeve 12 and the threaded groove 16 are mutually adapted. Both ends of the limit frame 14 are wound with torsion springs 15, and the threaded sleeve 12 and the limit frame 14 form an elastic structure through the torsion springs 15. The bottom end of the first docking plate 6 is provided with a limit block 17, and the upper end of the inner side of the limit frame 14 is provided with a limit groove 18 that matches the limit block 17. The cross-section of the limit block 17 is triangular. The outside of the threaded sleeve 12 is provided with anti-slip layers 13 at equal intervals, and the height of the anti-slip layers 13 is equal to the height of the threaded sleeve 12.

[0028] In this example, the material to be conveyed can be packaged through the feed inlet 4. The packaging bag body 1 is divided into multiple cavities, which can input different materials according to different needs. At the same time, the inner partition of the packaging bag body 1 is pressed and formed to avoid material mixing. By attaching the first docking plate 6 and the second docking plate 7 at the bottom of the feed inlet 4, the feed inlet 4 and the docking interface 5 are basically aligned in position. Then, the insertion tube 11 set inside the second docking plate 7 is inserted into the inside of the feed inlet 4 to realize the docking between the feed inlet 4 and the docking interface 5. Then, by rotating the threaded sleeve 12, the threaded sleeve 12 is threadedly connected to the threaded groove 16, so that the threaded sleeve 12 moves towards the second docking plate 7, and the limiting frame 14 is pulled outward and its angle is deflected. When the inner side of the limiting frame 14 moves to the top of the first docking plate 6, the force applied to the limiting frame 14 is removed, so that the limiting frame 14 is automatically reset by the elastic force of the torsion spring 15 and locked to the outside of the first docking plate 6. The limiting block 17 and the limiting groove 18 opened on the inner side of the limiting frame 14 engage with each other, so that the limiting frame 14 can stably engage and connect the first docking plate 6 and the second docking plate 7, which can effectively prevent the feed port 4 and the docking interface 5 from becoming loose after docking; the cross-section of the limiting block 17 is triangular, and the limiting block 17 and the limiting groove 18 engage with each other, so that the limiting frame 14 will not deflect outward due to external force during use, increasing the stability of the feed port 4 and the docking interface 5 when engaging; An anti-slip layer 13 is provided on the outer side of the threaded sleeve 12. When rotating the threaded sleeve 12, the anti-slip layer 13 can increase the friction, thereby making the rotation of the threaded sleeve 12 more stable and effectively preventing it from slipping out of the hand during rotation. A torsion spring 15 is wound around the hinge of the limiting frame 14. The torsion spring 15 enables the limiting frame 14 to automatically reset after angular deflection, so that the limiting frame 14 can always maintain a limited locking state between the first mating plate 6 and the second mating plate 7, increasing the stability during use.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution shown addresses the problem of gaps and vibrations caused by the connection between the feed inlet 4 and the docking port 5 during docking. The sterile multi-chamber packaging bag discloses a sealing mechanism. The docking port 5 has an internal sealing mechanism to prevent the insertion tube 11 from vibrating. The sealing mechanism includes an elastic airbag 8, which is engaged with the inside of the first docking plate 6. Two connecting tubes 9 are respectively provided on the inner side of the elastic airbag 8, and a sealing layer 10 is sleeved on the outer side of the insertion tube 11. The elastic airbag 8 and the sealing layer 10 are connected by the connecting tubes 9.

[0030] In this example, when the first docking plate 6 and the second docking plate 7 are docked, the second docking plate 7 applies a compressive force to the elastic airbag 8. At the same time, since the limiting frame 14 locks the first docking plate 6 and the second docking plate 7 together, the compressive force on the elastic airbag 8 remains unchanged. The gas inside the elastic airbag 8 is thus transported to the interior of the sealing layer 10 through the connecting pipe 9. The sealing layer 10 can fill the gap between the insertion pipe 11 and the feed port 4, thereby effectively preventing the insertion pipe 11 from shaking due to gaps when docking with the feed port 4, and increasing the stability during use.

[0031] Example 3: Figure 1 and Figure 2 The technical solution shown addresses the problems of easy tearing and wear on the outer side of the packaging bag body 1 due to friction and static electricity generation inside during use: the sterile multi-cavity packaging bag discloses a protective mechanism, with a wear-resistant layer 2 provided on the outer side of the packaging bag body 1 and an anti-static layer 3 provided on the inner side of the packaging bag body 1.

[0032] In this example, by providing a wear-resistant layer 2 on the outside of the packaging bag body 1, the wear resistance of the packaging bag body 1 can be increased, preventing the packaging bag body 1 from breaking due to friction, thereby effectively increasing the service life of the packaging bag body 1. Furthermore, by providing an antistatic layer 3 inside the packaging bag body 1, the packaging bag body 1 will not stick together and become inseparable even when subjected to external friction, thus increasing its applicability during use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
