The piston 4 is rotatably connected to the driving component, and the driving component drives the piston 4 to slide along the axial direction of the container body 7.

[0053] The container body 7 is a transparent shell with openings at both ends. The top opening of the container body 7 is sealed by the cover, and the bottom opening is sealed by the piston 4. The container body 7 is set as a transparent shell to facilitate viewing of the amount of medicine discharged. The container body 7 is provided with a scale 3 to improve the accuracy of the amount of medicine discharged. The bottom and top of the container body 7 here refer to the normal placement state of the container, such as Figure 1 state. Since the container body 7 is a transparent structure, its internal structure can also be seen in the figure. The piston 4 can be made of a transparent material or a non-transparent material, which is not limited here. The medicine is contained in the cavity surrounded by the container body 7, the piston 4 and the cover. The medicine can be liquid, solid or semi-solid, and is particularly suitable for oral Chinese medicine syrup.

[0054] The medicine packaging container of the utility model is configured by setting the container body 7 as a transparent shell, and setting the scale 3 on the container body 7, so that the piston 4 compresses the effective volume of the container body 7 to squeeze out the content; the piston 4 reaches a predetermined position, thereby discharging the medicine of the corresponding dose, and the one-way opening is provided on the cover to facilitate the one-way discharge of the medicine and avoid medicine contamination. The medicine packaging container of the utility model is convenient and fast to operate, can accurately and quantitatively obtain medicine, so that the patient can take the medicine in a more accurate dose, and at the same time avoids waste and contamination of liquid medicine.

[0055] The container body 7 includes a bottle mouth 701, a bottle shoulder 702 and a bottle body 704 connected together, and the bottle mouth 701, the bottle shoulder 702 and the bottle body 704 can be an integral structure. The end surface of the piston 4 close to the bottle mouth 701 is configured to have a contour consistent with the bottle shoulder 702 and the bottle mouth 701, and the size of this end surface of the piston 4 is consistent with the size of the corresponding positions of the bottle shoulder 702 and the bottle mouth 701. In one embodiment, as Figure 3 As shown, the bottle shoulder 702 is configured as a second conical surface. Figure 2 As shown, the surface of the piston 4 close to the bottle shoulder 701 is configured as a first conical surface 402, and the first conical surface 402 is arranged correspondingly to the second conical surface, that is, the taper of the two is the same, so that the first conical surface 402 of the piston 4 can fit with the second conical surface to avoid the waste of the medicine in the container body 7. In another embodiment, the bottle shoulder 702 can also be configured as a curved surface, and accordingly, the surface of the piston 4 close to the bottle shoulder 701 is also configured as a curved surface with the same contour. The material of the piston 4 is one or more of polypropylene, trifluoroethylene, polytetrafluoroethylene, and polyester.

[0056] In order to facilitate the movement of the piston 4, in one embodiment, the driving component includes a push rod 5 and a base 6, one end of the push rod 5 is threadedly connected to the piston 4, and the other end is plugged into the base 6, and the base 6 is rotatably connected to the container body 7. When the base 6 is rotated, the base 6 drives the push rod 5 to rotate, and the piston 4 moves along the inner wall of the container body 7.

[0057] In order to prevent the piston 4 from rotating in the circumferential direction, a first limiting structure is provided at the position where the piston 4 contacts the container body 7. The first limiting structure limits the circumferential movement of the piston 4 so that the piston 4 can only move in the axial direction. In one embodiment, the first limiting structure includes a first limiting ridge 405 and a first limiting groove 703 that are arranged in a coordinated manner. Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the piston 4.

The first limiting ridge 405 is arranged on the side wall where the piston 4 contacts the bottle body 704, and the first limiting ridge 405 is arranged parallel to the axis of the piston 4. The first limiting groove 703 is arranged on the inner side wall of the bottle body 704 of the container body 7, and the first limiting groove 703 extends along the sliding direction of the piston 4. It can be understood that in order to meet the stroke requirements of the piston 4, the length of the first limiting groove 703 is greater than the stroke length of the piston 4, and its length is at least equal to the sum of the stroke length of the piston and the length of the first limiting ridge 405. In order to improve the smoothness of the sliding of the piston 4, as Figure 4As shown, the cross section of the first limiting groove 703 is an arc-shaped groove, and the cross section of the first limiting ridge 405 is an arc-shaped protrusion, and the arc-shaped groove and the arc-shaped protrusion are arranged in coordination.

[0058] In order to facilitate the driving of the push rod 5 to rotate, the base 6 includes a first plug-in portion 603 and a second plug-in portion 602. Figures 5 to 7 The first plug-in portion 603 is arranged on the end surface of the base 6 close to the push rod 5, and the second plug-in portion 602 is arranged on the end surface of the base 6 away from the push rod 5. The first plug-in portion 603 is used to plug with the push rod 5, and the second plug-in portion 602 is used to plug with the driving component. In order to facilitate the plug-in connection, the push rod 5 is provided with a third plug-in portion 502. Figure 8 and Fig. 9 The third plug-in portion 502 is plugged into the first plug-in portion 603 correspondingly, and the second plug-in portion 602 is plugged into the fourth plug-in portion on the cover.

[0059] In one embodiment, the first plug-in portion 603 is a first plug-in groove. Figure 6 As shown, the third plug-in portion 502 is a first plug-in protrusion. Figure 8 As shown, the first insertion groove and the first insertion protrusion are correspondingly inserted. It can be understood that in order to prevent the circumferential relative movement of the insertion position of the base 6 and the push rod 5, the first insertion groove and the first insertion protrusion are both provided with side surfaces for limiting circumferential position, such as Figure 6 As shown, the first plug-in groove is a rectangular groove, and the groove side of the rectangular groove is the side that limits the circumferential motion. Correspondingly, the first plug-in protrusion is a rectangular block, and the side of the rectangular block is the side that limits the circumferential motion. In other embodiments, the first plug-in groove can also be a groove of other polygonal structures, which is not limited here.

[0060] In order to improve the sealing performance of the container, the sealing cover includes an inner cover 2 and an outer cover 1. The inner cover 2 is threadedly connected to the inner side wall of the bottle mouth 701, and the outer cover 1 is threadedly connected to the outer side wall of the bottle mouth 701, that is, the inner side wall and the outer side edge of the bottle mouth 701 are both provided with thread structures. The outer cover 1 is sleeved on the outer side of the inner cover 2. Specifically, a cylindrical convex ring 103 is provided on the end surface of the outer cover 1 close to the bottle mouth 701, as shown in FIG. Fig.11 and Fig.12 As shown, the inner wall of the convex ring 103 is provided with a connecting thread for connecting with the bottle mouth 701. The inner cover 2 is provided with the one-way opening, such as Fig.13 and 14 As shown, the one-way opening is a cross opening 201, and the cross opening 201 is a heart valve-shaped opening, so that the medicine in the container can only flow out but not flow in.

[0061] In order to facilitate the structure for driving the base 6 to rotate, a fourth plug-in portion is provided on the end surface of the outer cover 1 away from the inner cover 2, and the fourth plug-in portion is plugged with the second plug-in portion 602 on the base 6. One of the second plug-in portion 602 and the fourth plug-in portion is a second plug-in groove, and the other is a second plug-in protrusion, the second plug-in groove is plugged with the second plug-in protrusion correspondingly, and the second plug-in groove and the second plug-in protrusion are both provided with side surfaces for limiting circumferential positioning.

[0062] Further, the second plug-in portion 602 is the second plug-in groove, referring to Figure 7 , the fourth plug-in portion is the second plug-in protrusion, referring to Fig.10 The second plug-in portion 602 includes a main groove and a sub-groove 6021 arranged around the main groove. The main groove is connected to the sub-groove 6021. The sub-groove 6021 is a rectangular groove, and the main groove is a cylindrical groove. Correspondingly, the fourth plug-in portion includes a central protrusion 101 protruding from the end surface of the outer cover 1 and sub-protrusions 102 arranged around the central protrusion 101. The central protrusion 101 is connected to the sub-protrusion 102. The central protrusion 101 is a cylindrical protrusion. The central protrusion 101 is inserted into the main groove. The central protrusion 101 and the main groove are arranged in a corresponding manner. The sub-protrusion 102 is inserted into the sub-groove 6021. The sub-protrusion 102 is a triangular prism structure, and includes a yielding side surface 1021 and a driving side surface 1022. The driving side surface 1022 is arranged perpendicular to the end surface of the outer cover 1. The angle between the yielding side surface 1021 and the end surface of the outer cover 1 is an acute angle, thereby forming an inclined surface. Fig.10 When the sub-convex block 102 is inserted into the sub-groove 6021, the driving side surface 1022 contacts the groove side wall of the sub-groove 6021, and the yielding side surface 1021 cannot contact the groove side wall of the sub-groove 6021. Due to the existence of the yielding side surface 1021, the base 6 can only rotate in one direction, thereby making the push rod 5 rotate in one direction, and then making the piston 4 only move toward the bottle mouth 701, which can prevent the liquid from being sucked back when the base 6 rotates in the opposite direction.

[0063] In order to facilitate the connection between the piston 4 and the push rod 5, a threaded hole 404 is provided on the end surface of the piston 4 close to the base 6, and the threaded hole 404 is arranged along the axial direction of the piston 4.
