Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically to a liquid aseptic composite packaging bag. Background Technology

[0002] Liquid aseptic composite packaging bags are packaging bags made of a variety of different materials through a composite process. They can ensure that the liquid inside is in a sterile state during the packaging process, effectively preventing the invasion and reproduction of microorganisms, thereby extending the shelf life of the liquid.

[0003] It is generally composed of multiple layers of materials with different functions. The common structure includes an outer layer, a middle layer and an inner layer. The outer layer is usually made of materials such as polyester (PET) and nylon (PA), which have good printability and mechanical strength. The middle layer is usually made of materials such as aluminum foil (AL) or ethylene-vinyl alcohol copolymer (EVOH), which provide excellent barrier properties and block the transmission of oxygen, moisture and light. The inner layer is generally made of materials such as polyethylene (PE) or polypropylene (PP), which have good heat-sealing properties and chemical stability.

[0004] Most existing aseptic composite packaging bags for liquids use a relatively soft bag structure and lack effective bottom support. When placed on a flat surface (such as a table or workbench), they are prone to tipping over due to the uneven weight distribution of the liquid inside the bag and the softness of the bag itself. Especially after some liquid is poured out, the amount of liquid in the bag decreases, the center of gravity changes, and the risk of tipping increases further. This not only affects the user's operation of pouring out the liquid, but may also cause the liquid to spill, resulting in waste and pollution. Therefore, an aseptic composite packaging bag for liquids is proposed. Utility Model Content

[0031] 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.

[0032] This utility model provides a technical solution: a liquid aseptic composite packaging bag. Please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,include:

[0033] The bag body includes a protective layer 1, a barrier layer 2, and a stabilizing layer 3. The protective layer 1 is fixedly disposed on the outside of the barrier layer 2, and the stabilizing layer 3 is fixedly disposed on the inside of the barrier layer 2.

[0034] The discharge port 4 is fixedly set at the top of the bag body, and a top cover 6 is installed at the upper end of the discharge port 4;

[0035] The first side rod 10 is fixedly installed on the upper part of both sides of the outside of the bag body;

[0036] The second side rod 11 is fixedly installed on the lower part of both sides of the outside of the bag body;

[0037] The limiting sliding shell 12 is slidably disposed outside the first side rod 10 and the second side rod 11;

[0038] Bottom strip 13 is fixedly installed at the bottom of the bag body. A first gear 15 is rotatably installed on the front side of both ends of the lower part of the bottom strip 13, and a second gear 17 is rotatably installed on the rear side of both ends of the lower part of the bottom strip 13. The first gear 15 and the second gear 17 are meshed and connected.

[0039] The first support bar 14 is fixedly installed at the front end of the first gear 15;

[0040] The second support bar 16 is fixedly installed at the rear end of the second gear 17;

[0041] The protective layer 1 is made of nylon, the barrier layer 2 is made of aluminum foil, and the stabilizing layer 3 is made of polypropylene.

[0042] Please see Figure 1 , Figure 4 and Figure 5 The top cover 6 is connected to the discharge port 4 by a threaded connection, and the discharge port 4 is fixedly connected to the stabilizing layer 3.

[0043] Please see Figure 4 and Figure 5 The upper end of the discharge port 4 is equipped with a top frame 5 on both the front and rear sides, and the top frame 5 is fixedly connected to the discharge port 4.

[0044] Please see Figure 4 and Figure 5 A flap 7 is provided at the upper end of the discharge port 4, and the flap 7 is rotatably connected to the top frame 5. The flap 7 is used to cover the discharge port 4 to prevent debris from falling into the discharge port 4 after the top cover 6 is opened.

[0045] Please see Figure 5 A limiting baffle 9 is provided on the upper side of the flip plate 7 outside the discharge port 4, and the limiting baffle 9 is fixedly connected to the discharge port 4. The limiting baffle 9 is used to limit the upper part of one end of the flip plate 7.

[0046] Please see Figure 4 and Figure 5 A counterweight 8 is installed on the lower end of the flip plate 7 on the side away from the limiting baffle 9, and the counterweight 8 is fixedly connected to the flip plate 7. The counterweight 8 causes the flip plate 7 to flip downward to one side.

[0047] This solution: When the packaging bag needs to be upright, first slide the limiting sliding shell 12 to the connection point of the first side rod 10 and the second side rod 11, so that the first side rod 10 and the second side rod 11 are connected together under the wrapping of the limiting sliding shell 12, so that the two sides of the packaging bag are supported by the force. Then, pull the first support bar 14 outward. The first support bar 14 rotates around the first gear 15 as the axis. The first gear 15 drives the second gear 17, which in turn causes the second support bar 16 to rotate backward until the first support bar 14 and the second support bar 16 form a straight line, so that the bottom of the packaging bag is supported. When the top cover 6 is unscrewed, in the vertical state of the packaging bag, the counterweight 8 drives the flip plate 7 to keep the side away from the limiting baffle 9 in a downward flipped state. The side of the flip plate 7 close to the limiting baffle 9 is in contact with the lower end of the limiting baffle 9 and is limited. When the liquid in the packaging bag is poured out, the packaging bag tilts to one side, and the flip plate 7 opens to pour out the liquid.
