Technical Field
[0001] This utility model relates to the field of oral solid drug storage technology, specifically to an antistatic high-density polyethylene bottle for oral solid drugs. Background Technology
[0002] Polyethylene is a thermoplastic resin obtained by polymerizing ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, and has a waxy feel. It has excellent low-temperature resistance, good chemical stability, and can withstand the corrosion of most acids and alkalis. It is insoluble in common solvents at room temperature, has low water absorption, and excellent electrical insulation. Some existing high-density polyethylene bottles for oral solid medicines are used to store medicines.
[0003] In the prior art, patent CN202121464065.3 discloses a high-density polyethylene bottle for oral solid medicine, including a bottle body, a baffle, a sealing gasket, a bottle cap, a suction cup, a ventilation valve, and a dispensing mechanism. The baffle is fixedly sleeved on the outer wall of the bottom end of the bottle body, and a sealing gasket is adhered to the bottom of the baffle. The bottle cap is movably sleeved on the bottom end of the bottle body, and a suction cup is fixedly installed on the bottom of the bottle cap. The ventilation valve is connected to the left outer wall of the top of the suction cup, and a dispensing mechanism is provided inside the top of the bottle body.
[0004] The aforementioned high-density polyethylene bottles for oral solid medications have problems in practical use. If the polyethylene bottle body is rubbed, a large amount of charge will be generated. If these charges are not removed in time, they will form static electricity, which will affect the storage of oral solid medications. Therefore, we propose an antistatic high-density polyethylene bottle for oral solid medications. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an antistatic high-density polyethylene bottle for oral solid medicines, which prevents static electricity from affecting the storage of oral solid medicines and can effectively solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-density polyethylene bottle for antistatic oral solid medicine, comprising an outer shell and an antistatic spacer mechanism;
[0007] Casing: It has a screw cap on the upper side;
[0008] The anti-static mechanism includes vertical sliding grooves, guide strips, a polyethylene inner liner, a docking rotating seat, a plastic screw rod, a torsion block, and a threaded cylinder. The inner arc surface of the outer shell has evenly distributed vertical sliding grooves, each with a guide strip slidably connected inside. The guide strips are fixedly connected to the outer arc surface of a polyethylene inner liner on their respective sides facing the center of the outer shell. A docking rotating seat is fixedly connected to the center of the lower surface of the polyethylene inner liner, and a plastic screw rod is rotatably connected to the center of the lower surface of the docking rotating seat. A torsion block is fixedly connected to the lower end of the plastic screw rod. A threaded cylinder is located in the center of the lower surface of the outer shell, with its inner threaded surface threadedly connected to the outer threaded surface of the plastic screw rod to prevent static electricity from affecting the storage of oral solid medications.
[0009] Furthermore, the outer arc surface of the outer shell is provided with an outer spiral, and the outer shell is threadedly connected to the inner thread surface of the screw cap to realize the function of tightening the screw cap.
[0010] Furthermore, it also includes a circular slot, which is formed on the upper side wall of the screw cap. The upper side of the polyethylene inner liner is inserted into the interior of the circular slot to achieve the function of sealing the upper side.
[0011] Furthermore, the outer surface of the outer shell is provided with strip-shaped grooves, and metal strips are respectively provided inside the strip-shaped grooves. An annular metal ring is fixedly connected to the lower surface of the outer shell, and the lower ends of the six metal strips are fixedly connected to the upper end of the annular metal ring to realize the function of adsorbing charges.
[0012] Furthermore, the outer arc surface of the screw cap is provided with evenly distributed external anti-slip protrusions to prevent slippage when the screw cap is turned.
[0013] Furthermore, the lower surface of the outer shell is concave in the middle, and the twisting block is located inside the concave surface to prevent the twisting block from affecting the placement balance of the bottle.
[0014] Furthermore, there is a gap between the lower surface of the polyethylene inner liner and the lower side wall of the outer shell, and the height of the gap is the depth of the circular slot, thereby achieving a sealed oral solid medication.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This antistatic oral solid medicine high-density polyethylene bottle has the following advantages:
[0016] This high-density polyethylene bottle features a double-layer design. By adding conductive metal to the outside, most of the charge and information of the outer shell can be contained, while reducing the contact area between the outer shell and the polyethylene liner. Even if the outer shell generates charge due to friction, it will not be transferred to the polyethylene liner, preventing solid medicine from adsorbing onto the inner arc surface of the polyethylene liner and preventing static electricity from affecting the storage of oral solid medicines.

Detailed Implementation
[0024] 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.
[0025] Please see Figure 1-6 This embodiment provides a technical solution: an antistatic oral solid medicine high-density polyethylene bottle, including an outer shell 1 and an antistatic spacer mechanism 3;
[0026] Outer shell 1: It has a screw cap 2 on its upper side, and an outer screw 4 on the upper side of the outer arc surface of the outer shell 1. The inner thread surface of the outer shell 1 and the screw cap 2 are threadedly connected. The outer surface of the outer shell 1 has a strip groove 5. The inside of the strip groove 5 is provided with metal strips 6. The lower surface of the outer shell 1 is fixedly connected with an annular metal ring 7. Both the metal strips 6 and the annular metal ring 7 are made of iron. The lower ends of the six metal strips 6 are fixedly connected to the upper end of one annular metal ring 7. The outer arc surface of the screw cap 2 is provided with evenly distributed external anti-slip protrusions 9. The outer shell 1 is made of PVC material.
[0027] The anti-static mechanism 3 includes vertical sliding grooves 31, guide bars 32, a polyethylene inner liner 33, a docking pivot 34, a plastic lead screw 35, a torsion block 36, and a threaded cylinder 37. The inner arc surface of the outer shell 1 is provided with evenly distributed vertical sliding grooves 31. Guide bars 32 are slidably connected inside each vertical sliding groove 31. The guide bars 32 are fixedly connected to the outer arc surface of a polyethylene inner liner 33 on the side facing the center of the outer shell 1. The polyethylene inner liner 33 is made of high-molecular-weight PE material. The outer arc surface of the polyethylene inner liner 33 does not contact the inner arc surface of the outer shell 1. The lower surface of the polyethylene inner liner 33 is fixedly connected to the middle... The device includes a docking pivot 34, with a plastic lead screw 35 rotatably connected to the center of its lower surface. A torsion block 36 is fixedly connected to the lower end of the plastic lead screw 35. A threaded cylinder 37 is located in the center of the lower surface of the outer casing 1, with its internal thread surface threaded to the external thread surface of the plastic lead screw 35. It also includes a circular slot 8, which is located on the upper side wall of the screw cap 2. The upper side of the polyethylene inner liner 33 is inserted into the circular slot 8. When the high-density polyethylene bottle for oral solid medication is needed, a specified amount of oral solid medication can be added to the polyethylene inner liner 33. Then, the screw cap 2 can be closed and tightened by the outer screw 4 and the inner thread surface of the screw cap 2. At this time, the toggle block 36 can be turned, which will drive the plastic screw rod 35 to rotate. Due to the threaded connection between the plastic screw rod 35 and the threaded cylinder 37, the plastic screw rod 35 will lift the polyethylene inner liner 33 upward during rotation, forcing the polyethylene inner liner 33 to move upward until the upper side of the polyethylene inner liner 33 is inserted into the circular slot 8 and tightened. At this time, the polyethylene bottle can be used. Before the polyethylene bottle is used, the charge accumulated in the polyethylene inner liner 33 will be guided by the guide strip 32. When the material is delivered to the outer shell 1, the metal strip 6 and the annular metal ring 7 on the surface of the outer shell 1 will be charged. If the metal strip 6 and the annular metal ring 7 come into contact with the surface of a conductive object, the charge will be directly conducted out. The contact area between the polyethylene inner liner 33 and the outer shell 1 is relatively small, and the polyethylene inner liner 33 will not generate a large amount of charge due to friction with the inner arc surface area of the outer shell 1, thus avoiding the formation of static electricity. The lower surface of the outer shell 1 is concave in the middle, and the twist block 36 is located inside the concave surface. There is a gap between the lower surface of the polyethylene inner liner 33 and the lower side wall of the outer shell 1, and the height of the gap is the depth of the circular slot 8.
[0028] The working principle of the antistatic oral solid medicine high-density polyethylene bottle provided by this utility model is as follows: When the oral solid medicine high-density polyethylene bottle is needed, a specified amount of oral solid medicine can be added into the polyethylene inner liner 33, and then the screw cap 2 can be closed. The screw cap 2 is tightened by the outer screw 4 and the inner thread surface of the screw cap 2. At this time, the torsion block 36 can be turned, which will drive the plastic screw rod 35 to rotate. Due to the threaded connection between the plastic screw rod 35 and the threaded cylinder 37, during the rotation of the plastic screw rod 35, the polyethylene inner liner 33 is lifted upward, forcing the polyethylene inner liner 33 to move upward until the upper side of the polyethylene inner liner 33 is inserted into the circular slot 8 and tightened. At this time, the bottle can be used. Using this polyethylene bottle, before use, the charge accumulated in the polyethylene inner liner 33 is transported to the outer shell 1 through the guide strip 32. The metal band 6 and the annular metal ring 7 on the surface of the outer shell 1 are both charged. If the metal band 6 and the annular metal ring 7 come into contact with the surface of a conductive object, the charge is directly conducted out. The contact area between the polyethylene inner liner 33 and the outer shell 1 is small, and the polyethylene inner liner 33 will not generate a large amount of charge due to friction with the inner arc surface area of the outer shell 1, thus forming static electricity. The lower surface of the outer shell 1 is concave in the middle, and the twist block 36 is located inside the concave surface. There is a gap between the lower surface of the polyethylene inner liner 33 and the lower side wall of the outer shell 1, and the height of the gap is the depth of the circular slot 8.
[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
