Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medicine bottles, and particularly to a medicine bottle and a medicine liquid quantitative extraction set capable of reducing medicine liquid pollution. BACKGROUND

[0002] When a pet is ill, a veterinarian usually uses a needleless syringe to quantitatively extract medicine liquid from a medicine bottle and then feeds or applies the medicine liquid to the pet. Because the liquid extraction end of the syringe is short (usually only a few millimeters), it is not convenient to directly insert the liquid extraction end into the medicine bottle to extract medicine liquid, so the usual practice is to first pour the medicine liquid into a cup and then use the syringe to extract the required dose. However, this method is prone to cause the medicine liquid to be contaminated by the external environment. Patent document CN204355509U discloses a medicine bottle capable of reducing medicine liquid pollution. A bottle stopper is installed at the bottle mouth of the medicine bottle. The bottle stopper is provided with a circular liquid extraction hole. A circular ring-shaped needle clamping portion is arranged on the side of the bottle stopper around the liquid extraction hole. When the needleless syringe is used to quantitatively extract medicine liquid, the following operations are performed: the medicine liquid does not need to be poured into other containers. The liquid extraction end of the syringe is only inserted into the liquid extraction hole from top to bottom. During this process, the needle clamping portion of the bottle stopper clamps the liquid extraction end of the syringe outside to seal it. Then, the medicine bottle is inverted, and the medicine liquid in the bottle is quantitatively extracted by the syringe. During this process, the needle clamping portion of the bottle stopper can effectively prevent the medicine liquid from leaking along the outer wall of the liquid extraction end of the syringe to the external environment. After the liquid extraction, the medicine bottle is placed upright, and then the syringe is pulled out. Because the medicine liquid does not need to be poured into other containers when the medicine liquid is quantitatively extracted, the risk of the medicine liquid being contaminated can be reduced. The medicine bottle has two styles: (1) the top of the needle clamping portion is lower than the bottle mouth. The liquid extraction end of the syringe needs to be inserted into the bottle mouth to be inserted into the liquid extraction hole. However, during this process, the liquid extraction end of the syringe may accidentally contact other parts of the bottle stopper, which is prone to be contaminated. (2) the top of the needle clamping portion is flush with the bottle mouth. When the liquid extraction end of the syringe is completely inserted into the liquid extraction hole, the bottom of the syringe barrel is flush with the edge of the bottle mouth, which has a risk of contacting the edge of the bottle mouth, which may also cause the syringe to be contaminated. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a medicine bottle capable of reducing medicine liquid pollution. When a needleless syringe is used to quantitatively extract medicine liquid from a medicine bottle, the syringe is not prone to be contaminated. The utility model also provides a medicine liquid quantitative extraction set capable of reducing medicine liquid pollution. When a needleless syringe in the set is used to quantitatively extract medicine liquid from a medicine bottle, the syringe is not prone to be contaminated.

[0004] To solve the above technical problem, the utility model discloses a medicine bottle capable of reducing medicine liquid pollution. A bottle stopper is installed at the top of the bottle mouth. The bottle stopper is provided with a circular liquid extraction hole for the liquid extraction end of the syringe to be inserted to quantitatively extract the medicine liquid in the bottle. The hole wall of the liquid extraction hole serves as a needle clamping portion for clamping the liquid extraction end of the syringe outside to seal it. The top of the needle clamping portion is higher than the bottle mouth.

[0005] Furthermore, this includes the bottle cap that covers the outside of the bottle stopper.

[0006] Furthermore, the bottle cap extends inwards towards the syringe barrel, where a first sealing section seals the liquid extraction port; or

[0007] The bottle cap extends outward from the syringe clamping part, with a second sealing part that covers the syringe clamping part to seal the liquid extraction port; or

[0008] The bottle cap has a first sealing part extending inward to the syringe clamping part and a second sealing part extending outward to the syringe clamping part. The first and second sealing parts together clamp the syringe clamping part of the bottle stopper, thereby sealing the liquid extraction port.

[0009] Furthermore, both the syringe clamping part and the first sealing part are annular and concentric; or

[0010] The syringe barrel section and the second sealing section are both annular and concentric; or

[0011] The first and second sealing sections and the needle clamping section are all circular and concentric.

[0012] Furthermore, the bottle cap is specifically threaded onto the bottle opening.

[0013] Furthermore, the bottle cap includes an inner and an outer cap body. The inner cap body is threaded to the bottle mouth and has a first ratchet. The outer cap body covers the outside of the inner cap body and has a second ratchet that engages with the first ratchet. The outer cap body is exposed for rotation. When the outer cap body is rotated in the forward direction, the second ratchet, through the first ratchet, causes the inner cap body to be rotated in the forward direction to tighten. When the outer cap body is rotated in the reverse direction, the second ratchet moves upward along the first ratchet and passes over the first ratchet, thereby causing the outer cap body to rotate in the opposite direction relative to the inner cap body. When the outer cap body presses down on the inner cap body and rotates in the reverse direction, the second ratchet, through the first ratchet, causes the inner cap body to be rotated in the reverse direction to loosen.

[0014] Furthermore, the outer wall of the inner cover has an annular groove, and the inner wall of the outer cover has an annular block. The block is inserted into the groove and can slide upward along the groove. The outer cover is thus installed on the inner cover.

[0015] Furthermore, the bottle stopper has a groove on its inner side, and a protrusion extends upward from the center of the bottom wall of the groove. The liquid extraction hole is located on the protrusion, which serves as the wall of the liquid extraction hole.

[0016] The drug liquid quantitative extraction kit includes a medicine bottle for storing the drug liquid and a needleless syringe for quantitatively extracting the drug liquid from the medicine bottle. As described above, the syringe's extraction end is inserted into the extraction port of the medicine bottle's stopper to quantitatively extract the drug liquid from the bottle. The syringe clamping part of the medicine bottle's stopper clamps the syringe's extraction end on the outside of the syringe's extraction end to seal it.

[0017] When the medicine is drawn by the needleless syringe, the syringe drawing end is inserted into the drawing hole of the bottle plug from top to bottom, and then the medicine bottle is inverted to draw the medicine by the syringe. The medicine is not poured into other containers, so that the risk of contamination of the medicine is reduced. Since the top of the bottle plug clamping the syringe is higher than the bottle mouth, the syringe drawing end can be directly inserted into the drawing hole without extending into the bottle mouth, so that the possibility of the syringe drawing end accidentally contacting other parts of the bottle plug is reduced, and the syringe drawing end is not easily contaminated. When the syringe drawing end is completely inserted into the drawing hole, the bottom of the syringe barrel is higher than the edge of the bottle mouth, so that the syringe barrel is prevented from contacting the edge of the bottle mouth, and the syringe barrel is not easily contaminated.

[0028] The present application will be further described in detail below in conjunction with the specific embodiments.

[0029] The medicine liquid quantitative drawing set is shown in Figure 1 and Figure 3 , which comprises a medicine bottle 1 and a needleless syringe 2. The medicine bottle 1 is shown in Figure 2 and Figure 3, including bottle body 11, bottle body 11 stores liquid medicine (not shown in the figure), bottle mouth 110 at the top of bottle body 11 is installed with bottle plug 12, recess 120 is opened in the inside of bottle plug 12, the center of bottom wall 121 of recess 120 extends upward with wide bottom and narrow top convex part 123, the top 1231 of convex part 123 is higher than bottle mouth 110 and the center of which is opened with circular vertical through hole 122 of wide bottom and narrow top, convex part 123 is as the circular hole wall of vertical through hole 122. Bottle plug 12 is covered with bottle cap 13. When using needle cylinder 2 to quantitatively extract medicine, vertical through hole 122 is as liquid extraction hole, needle cylinder 2 extraction end 21 is inserted into it to quantitatively extract liquid medicine in the bottle, the specific operation is as follows: first, open bottle cap 13, then insert needle cylinder 2 extraction end 21 from top to bottom into the vertical through hole 122 of bottle plug 12 of medicine bottle 1, in this process, the top 1231 of convex part 123 is as needle clamping part, clamps needle cylinder 2 extraction end 21 outside to seal; then, invert medicine bottle 1, use needle cylinder 2 to quantitatively extract liquid medicine in the bottle, in this process, the top 1231 of convex part 123 can effectively prevent liquid medicine from leaking along the outer wall of needle cylinder 2 extraction end 21 to the external environment; after extraction, place medicine bottle 1 vertically and then pull out needle cylinder 2. Since the liquid medicine does not need to be poured from medicine bottle 1 to other containers when quantitatively extracting medicine, the risk of liquid medicine being contaminated can be reduced. Since the needle clamping part (i.e. the top 1231 of convex part 123) of bottle plug 12 is higher than bottle mouth 110, needle cylinder 2 extraction end 21 does not need to extend into bottle mouth 110, but can be directly inserted into liquid extraction hole 122, reducing the possibility of needle cylinder 2 extraction end 21 accidentally contacting other parts of bottle plug 12, needle cylinder 2 extraction end 21 is not easy to be contaminated. When needle cylinder 2 extraction end 21 is completely inserted into liquid extraction hole 122, the bottom of needle cylinder 2 cylinder body 22 is higher than the edge of bottle mouth 110, so that needle cylinder 2 cylinder body 22 can avoid contacting the edge of bottle mouth 110, needle cylinder 2 cylinder body 22 is not easy to be contaminated. Although needle cylinder 2 cylinder body 22 will contact the top wall of convex part 123, since convex part 123 is located at the center of bottle plug 12, it is not easy to contact external contaminants like the edge of bottle mouth 110, that is, the top wall of convex part 123 is cleaner than the edge of bottle mouth 110, needle cylinder 2 cylinder body 22 is not easy to be contaminated even if it contacts the top wall of convex part 123.

[0030] See Figure 4 and Figure 5The bottle cap 13 has a first annular sealing part 131 extending inward from the protrusion 123 and a second annular sealing part 132 extending outward from the protrusion 123. Both sealing parts 131 and 132 are concentric with the protrusion 123. The first sealing part 131 is close to the top 1231 of the protrusion 123 on the inside of the top 1231 of the protrusion 123. The second sealing part 132 is wider at the bottom and narrower at the top, and it covers the entire protrusion 123 on the outside of the protrusion 123. The first and second sealing parts 131 and 132 together clamp the top 1231 of the protrusion 123, thereby sealing the vertical through hole 122. After long-term use, a small amount of medicine will inevitably leak from the first and second sealing parts 131 and 132. However, since there is a groove 120 on the inner side of the bottle stopper 12, the leaked medicine will flow to the outer periphery of the protrusion 123 and will be temporarily stored in the groove 120. When the bottle cap 13 is opened, it will not flow out directly and contaminate the outside.

[0031] See Figure 2 , Figure 5 and Figure 6 The bottle cap 13 includes inner and outer cap bodies 133 and 134. The inner cap body 133 is threaded to the bottle opening 110. First and second sealing portions 131 and 132 are provided on the inner cap body 133, and the outer top wall of the inner cap body 133 is provided with a first ratchet 1331. The outer cap body 134 covers the outside of the inner cap body 133 and is exposed. The inner top wall of the outer cap body 134 is provided with a second ratchet 1341, such as... Figure 7 The second ratchet 1341 engages with the first ratchet 1331. An annular groove 1332 is formed on the outer wall of the inner cover 133, and an annular block 1342 is provided on the inner wall of the outer cover 134. The block 1342 engages in the groove 1332 and can slide upwards along the groove 1332. The outer cover 134 is thus mounted on the inner cover 133. The first ratchet 1331 and the second ratchet 1341 cooperate to prevent the outer cover 134 from rotating forward relative to the inner cover 133, allowing only reverse rotation. Specifically: when the operator rotates the outer cover 134 forward, as... Figure 8 The second ratchet 1341, through the first ratchet 1331, drives the inner cover 133 to tighten in the forward direction; if the operator simply rotates the outer cover 134 in the reverse direction, such as... Figure 9 The second ratchet 1341 moves upward along the first ratchet 1331, passing over the first ratchet 1331, thus causing the outer cap 134 to rotate in the opposite direction relative to the inner cap 133. This reduces the possibility of children accidentally unscrewing the bottle cap 13; see Figure 7 The operator must press down on the outer cover 134 while rotating it in the opposite direction so that the outer cover 134 presses down on the inner cover 133, thereby preventing the second ratchet 1341 from moving upward. Only then will the second ratchet 1341 drive the inner cover 133 to rotate in the opposite direction and loosen it through the first ratchet 1331.

[0032] See Figure 5In other embodiments, the bottle cap 13 is modified to have only a circular first sealing portion 131, which is concentric with the protruding portion 123 and tightly adheres to the top 1231 of the protruding portion 123 inside the top 1231 to seal the liquid outlet 122; or the bottle cap 13 is modified to have only a circular second sealing portion 132, which is concentric with the protruding portion 123, has a wide bottom and a narrow top, and covers the entire protruding portion 123 outside the protruding portion 123 to seal the liquid outlet 122.

[0033] In other embodiments, the second sealing portion 132 of the bottle cap 13 is modified to: Figure 5 cover only the top 1231 of the protruding portion 123; or Figure 10 cover only the bottom of the protruding portion 123.

[0034] The above description is only an embodiment of the present application and does not limit the scope of patent protection. Those skilled in the art can make non-essential changes or substitutions based on the present application, which still falls within the scope of patent protection.
