Description

Technical Field

[0001] This utility model relates to the field of solution packaging bag technology, specifically to a packaging bag for pharmaceutical reagent solutions. Background Technology

[0002] Pharmaceutical reagent solution packaging bags are specialized containers made of chemically inert materials, possessing sealing and anti-contamination properties. They are used to hold various solution-type pharmaceuticals, preventing chemical reactions between the packaging material and the contents. They can prevent reagent leakage, volatilization, or deterioration due to external environmental influences, while ensuring the stability and safety of reagents during storage, transportation, and use. They are a key packaging form for ensuring the quality of reagent products in the circulation and use process.

[0003] In the prior art, a liquid packaging bag with patent application number CN201920708676.4 includes a bag body and a bag neck. The bag body has a cavity for holding liquid. The bag neck is connected to the upper part of the bag body and is provided with a flow channel for liquid outflow. The flow channel and the cavity are connected by a tortuous flow channel. Easy-tear openings are provided symmetrically on both sides of the bag neck. The easy-tear openings are used to tear open the bag neck to expose the flow channel opening. Because a tortuous liquid flow channel is provided between the flow channel opening of the liquid outlet of the liquid packaging bag and the cavity for storing liquid in the liquid packaging bag, the tortuous flow channel can reduce the pressure caused by holding the bag body and tearing the flow channel opening, so that the liquid inside the liquid packaging bag is not easy to spill and is convenient to use.

[0004] The aforementioned comparative document, by setting a tortuous flow channel between the cavity and the flow channel opening, combined with a symmetrical easy-tear opening design at the bag neck, can reduce the liquid impact caused by the pressure on the bag body when the flow channel opening is torn, effectively preventing liquid spillage and improving ease of use. However, when the liquid medicine is poured out from the packaging bag body, due to the narrow outlet of the bag body flow channel and the existence of residual dead corners, the liquid medicine cannot be completely discharged. During manual squeezing, due to uneven force and unidirectional influence, the bag body is prone to local wrinkles rather than overall expansion, further hindering the discharge of residual liquid medicine, ultimately resulting in liquid medicine waste and increased material costs. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a packaging bag for pharmaceutical reagent solutions, which can effectively solve the problem that the liquid medicine cannot be completely discharged when it is poured out of the packaging bag body due to the narrow flow channel outlet and the existence of residual dead corners.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a packaging bag for pharmaceutical reagent solutions, including a main component, including a packaging bag body, and a discharge frame fixed to the top of the packaging bag body;

[0008] An auxiliary component, disposed on the packaging bag body, includes an auxiliary part, the auxiliary part including a rotating rod, the rotating rod being fixed to one side of the packaging bag body, a pressure plate being disposed on one side of the packaging bag body, and a stop tube being fixed to the top of the discharge frame.

[0009] Furthermore, the auxiliary component also includes an extrusion member, which includes a support frame. The support frame is sleeved on the outside of the rotating rod and is rotatably connected to the rotating rod. A knob is fixed on one side of the rotating rod.

[0010] Furthermore, a slider is fixed on one side of the pressure plate, and a groove corresponding to the slider is opened on one side of the support frame, and the slider is slidably connected to the groove.

[0011] Furthermore, an elastic block is fixed to the inner wall of the groove, and one side of the elastic block is set as an inclined surface.

[0012] Furthermore, a movable plate is fixed to one side of the pressure plate, and the movable plate is fixed to one side of the support frame with glue. The knob is also fixed to one side of the support frame with glue.

[0013] Furthermore, the auxiliary component also includes a stopper, which includes a baffle fixed to the inner wall of the stopper tube, and a sealing plug is provided on one side of the baffle.

[0014] Furthermore, a threaded rod is fixed to the top of the sealing plug, and the threaded rod is threadedly connected to the stop pipe.

[0015] Furthermore, a turntable is fixed to the top of the threaded rod, and the turntable is fixed to one side of the stop tube by adhesive.

[0016] Compared with the known prior art, the technical solution provided by this utility model has the following beneficial effects: during the liquid pouring stage, the bag body can be rolled and squeezed. During the rolling process, the bag body is gradually rolled from the end towards the flow channel. The squeezing force is evenly transmitted along the axial direction of the bag body and acts on the residual dead corner area, overcoming the defects of uneven force and single direction of manual squeezing, pushing the liquid medicine stuck in the dead corner to move towards the flow channel, improving the liquid medicine discharge rate and reducing material loss.

[0017] It can stop the outflow of liquid medicine in real time, preventing the liquid medicine from seeping into the side wall of the bag after the bag is upright, improving the controllability and safety of the liquid medicine pouring operation, and reducing the risk of loss and pollution.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: A packaging bag for a pharmaceutical reagent solution, see attached document. Figure 1 -Appendix Figure 5 It includes a main component 1, including a packaging bag body 11, and a discharge frame 12 fixed to the top of the packaging bag body 11;

[0028] The packaging bag body 11 is sealed, pollution-proof, and chemical-resistant, which can prevent the packaging from reacting with the liquid medicine and prevent the liquid medicine from leaking, evaporating, or deteriorating. The discharge frame 12 guides the liquid medicine in the packaging bag body 11 to flow out in a directional manner to avoid spillage when pouring. At the same time, it provides an installation reference for the stop tube 213. The flow channel structure is adapted to the uniform liquid flow generated by the winding and squeezing, ensuring that the residual liquid medicine can smoothly enter the flow channel, ensuring the smoothness and integrity of the liquid medicine discharge, and meeting the quantitative pouring requirements.

[0029] Auxiliary component 2 is set on the packaging bag body 11 and includes auxiliary component 21. Auxiliary component 21 includes a rotating rod 211. The rotating rod 211 is fixed to one side of the packaging bag body 11. A pressure plate 212 is set on one side of the packaging bag body 11. A stop tube 213 is fixed on the top of the discharge frame 12.

[0030] The rotating rod 211 is rotatably connected to the support frame 221. Driven by the knob 222, it drives the packaging bag body 11 to wind from the end toward the discharge frame 12, converting the rotational power into a uniform extrusion force along the axial direction of the bag body. This pushes the stagnant liquid medicine to move into the flow channel. By pressing the pressure plate 212, it squeezes the packaging bag body 11. Then, the rotating rod 211 rotates, and the pressure plate 212 continuously squeezes the packaging bag body 11. During rotation, the liquid medicine inside the packaging bag body 11 can be squeezed out. The stop tube 213 is a component for controlling and stopping the outflow of liquid medicine. Through the cooperation of the sealing plug 232 and the baffle 231, the outflow of liquid medicine can be stopped in real time, preventing the liquid medicine from leaking after the packaging bag body 11 is straightened. This improves the controllability and safety of the pouring operation and reduces the risk of loss and pollution.

[0031] Specifically, the auxiliary component 2 also includes an extrusion member 22, which includes a support frame 221. The support frame 221 is sleeved on the outside of the rotating rod 211 and is rotatably connected to the rotating rod 211. A knob 222 is fixed on one side of the rotating rod 211.

[0032] The support frame 221 provides a stable rotation fulcrum for the rotating rod 211, ensuring smooth transmission of winding power. The slide groove 224 provides a sliding guide for the slider 223, restricting the movement trajectory of the pressure plate 212. At the same time, it fixes the movable plate 226, improving the reliability of the overall structure. The rotating rod 211 can be driven to rotate by rotating the knob 222.

[0033] Furthermore, a slider 223 is fixed on one side of the pressure plate 212, and a groove 224 corresponding to the slider 223 is opened on one side of the support frame 221. The slider 223 is slidably connected to the groove 224.

[0034] The slider 223 slides along the sliding track of the groove 224 to ensure that the pressure plate 212 moves smoothly and avoids uneven extrusion pressure caused by the offset of the pressure plate 212. In conjunction with the elastic block 225, it can form a limit at a specified position to ensure the stability of the pressure plate 212 during the extrusion process and further improve the uniformity of the extrusion effect.

[0035] Preferably, an elastic block 225 is fixed to the inner wall of the groove 224, and one side of the elastic block 225 is set as an inclined surface.

[0036] The elastic block 225 is an elastic component that works with the slider 223 to achieve limiting. Its inclined structure facilitates the sliding of the slider 223. At the same time, it uses elastic deformation to generate a reverse force on the slider 223, thereby fixing the pressure plate 212 in the support position, ensuring the squeezing effect and structural stability, and improving the reliability of use.

[0037] It should be noted that a movable plate 226 is fixed to one side of the pressure plate 212. The movable plate 226 is fixed to one side of the support frame 221 by glue, and the knob 222 is fixed to one side of the support frame 221 by glue.

[0038] Pressing the movable plate 226 can move the pressure plate 212, making the pressure plate 212 fit tightly against one side of the packaging bag body 11. When the operator applies external force to press the movable plate 226, the glue can be disconnected from the support frame 221, so that the movable plate 226 can move normally. Under normal conditions, the glue can fix the position of the pressure plate 212 and prevent the pressure plate 212 from shifting. The glue on the knob 222 works in the same way as the pressure plate 212.

[0039] Furthermore, the auxiliary component 2 also includes a stop member 23, which includes a baffle 231. The baffle 231 is fixed to the inner wall of the stop tube 213, and a sealing plug 232 is provided on one side of the baffle 231.

[0040] The baffle 231 and the sealing plug 232 cooperate to form a sealing surface. When the sealing plug 232 is in contact with the baffle 231, it can block the flow channel of the medicine and achieve the shut-off function. The sealing plug 232 moves towards the baffle 231 and fits into it through the drive of the threaded rod 233 to form a seal. When it moves in the opposite direction, it opens the flow channel and allows the medicine to flow out. The flow state of the medicine can be adjusted in real time to avoid accidental leakage during the pouring process and improve the safety of use.

[0041] Specifically, a threaded rod 233 is fixed to the top of the sealing plug 232, and the threaded rod 233 is threadedly connected to the stop tube 213.

[0042] The threaded rod 233 uses the threaded transmission principle to convert the rotational motion of the turntable 234 into the linear motion of the sealing plug 232, so as to realize the contact or separation of the sealing plug 232 and the baffle 231. This allows the sealing plug 232 to be stably maintained in any position, ensuring the reliability of the cut-off state and the convenience of adjustment.

[0043] Preferably, a turntable 234 is fixed to the top of the threaded rod 233, and the turntable 234 is fixed to one side of the stop tube 213 by glue.

[0044] The operator applies external force to the turntable 234 to rotate it, and then the glue is disconnected from the stop tube 213. The rotation drives the threaded rod 233 to rotate synchronously, thereby controlling the movement of the sealing plug 232.

[0045] When using the medicine reagent solution, first hold the stop tube 213 and apply external force to rotate the turntable 234, so that the glue between the turntable 234 and the stop tube 213 breaks. The turntable 234 drives the threaded rod 233 to rotate. The threaded rod 233 is threadedly engaged with the stop tube 213, which drives the sealing plug 232 away from the baffle 231 and opens the medicine solution outflow channel.

[0046] Then, the movable plate 226 is pressed, causing the glue between the movable plate 226 and the support frame 221 to break. The movable plate 226 drives the pressure plate 212 to move towards the packaging bag body 11 until the pressure plate 212 is tightly attached to the packaging bag body 11. The pressure plate 212 drives the slider 223 to slide along the slide groove 224, squeezing the elastic block 225. After the elastic block 225 deforms elastically, it limits the slider 223 and fixes the position of the pressure plate 212.

[0047] Then, turn knob 222 to break the glue between knob 222 and support frame 221. Knob 222 drives rotating rod 211 to rotate. Rotating rod 211 drives the packaging bag body 11 to gradually wind from the end towards the discharge frame 12. The squeezing force is evenly transmitted along the axial direction of the bag body, acting on the residual dead corner area, pushing the stagnant medicine liquid to move towards the flow channel, and improving the medicine liquid discharge rate.

[0048] The liquid medicine flows out through the discharge frame 12 and the stop pipe 213 in a directional manner. After the quantitative pouring is completed, the turntable 234 is rotated in the opposite direction, which drives the threaded rod 233 and the sealing plug 232 to move towards the baffle 231. The sealing plug 232 fits against the baffle 231 to stop the liquid medicine from flowing out and prevent the liquid medicine from leaking after the bag is straightened.

[0049] In summary, during the liquid pouring stage, the packaging bag body 11 can be rolled and squeezed. During the rolling process, the packaging bag body 11 is gradually rolled from the end towards the flow channel. The squeezing force is evenly transmitted along the axial direction of the bag body and acts on the residual dead corner area. This overcomes the defects of uneven force and single direction of manual squeezing, and pushes the liquid medicine stuck in the dead corner to move towards the flow channel, thereby improving the liquid medicine discharge rate and reducing material loss.

[0050] It can stop the outflow of liquid medicine in real time, preventing the liquid medicine from leaking to the side wall of the packaging bag body 11 after the packaging bag body 11 is upright, improving the controllability and safety of the liquid medicine pouring operation, and reducing the risk of loss and pollution.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
