Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a bottle cap and a sample bottle. Background Technology

[0002] Hospitals and medical laboratories typically use sample vials to store sample solutions for subsequent testing and processing. Sample vials usually consist of a cap and a body. When the cap is open, the sample solution flows into or out of the vial. When the cap is closed, it covers the open end of the vial, isolating the inside of the vial from the outside and preventing evaporation or leakage.

[0003] Based on this, related technologies propose isolating the inside of the bottle from the outside by inserting at least a portion of the bottle cap into the open end of the bottle body. However, during transportation, sample bottles containing sample solutions are prone to leakage from the bottle cap if subjected to vibration or pressure changes. Therefore, current sample bottles suffer from poor overall sealing due to the inadequate sealing of the bottle cap. Utility Model Content

[0004] This application provides a bottle cap and a sample bottle, aiming to solve the technical problem of poor sealing performance of the bottle cap.

[0005] In a first aspect, this application provides a bottle cap, comprising: A connector having a first opening and a second opening opposite to each other, the second opening being used to connect to a bottle body; and A sealing element is used to open or close the first opening.

When the first protrusion is provided on the outer wall of the first sealing part, the first sub-protrusion has a third slope relative to the outer wall of the first sealing part, and the second sub-protrusion has a fourth slope relative to the outer wall of the first sealing part, the fourth slope being greater than the third slope.

[0009] In one embodiment, the seal further includes a second sealing portion disposed on the first main body portion. The second sealing portion extends along the outer edge of the first main body portion, and when the bottle cap is in the closed state, the end of the second sealing portion away from the first main body portion abuts against the second main body portion.

[0010] In one embodiment, a boss is formed on the first main body portion extending radially outward from the connection between the first main body portion and the second sealing portion.

[0011] In one embodiment, the first main body portion and the second main body portion are rotatably connected.

[0012] In one embodiment, the bottle cap further includes a rotation limiting component; The first rotation limiting part of the rotation limiting assembly is disposed on the second main body part, and the first rotation limiting part is located on the side of the second main body part away from the second connecting part; The second rotation limiting part of the rotation limiting assembly is disposed on the first main body part; When the bottle cap is in the open state, the second rotation limiting part abuts against the first rotation limiting part, so that the included angle between the first main body part and the second main body part is maintained as a right angle or an acute angle.

[0013] In one embodiment, a second protrusion is provided on the inner wall of the second connecting portion. The second protrusion is located at the second end of the second connecting portion, which is the end of the second connecting portion close to the second main body portion. A plurality of the second protrusions are arranged at intervals along the circumference of the second connecting portion.

[0014] In one embodiment, the second protrusion includes a third sub-protrusion and a fourth sub-protrusion, the extension directions of the third and fourth sub-protrusions being parallel to the axial direction of the second connecting portion, the fourth sub-protrusion being continuous with the third sub-protrusion, and the fourth sub-protrusion being located between the third sub-protrusion and the second end; wherein, The third sub-protrusion has a first thickness relative to the inner wall of the second connecting portion, and the fourth sub-protrusion has a second thickness relative to the inner wall of the second connecting portion.

[0026] This application provides a bottle cap 100, such as Figures 1 to 5 As shown, the bottle cap 100 includes a sealing element 20 and a connecting element 10.

[0027] The connector 10 has a first opening 1001 and a second opening 1002. The first opening 1001 and the second opening 1002 are arranged opposite to each other. The first opening 1001 is used to connect the sealing member 20, and the second opening 1002 is used to connect the bottle body.

[0028] The seal 20 is used to open or close the first opening 1001.

[0029] like Figure 1 as well as Figure 2 As shown, with the seal 20 closing the first opening 1001, the bottle cap 100 is in the closed state. When the bottle cap 100 is in the closed state, at least a portion of the seal 20 extends into the first opening 1001, thereby blocking and sealing the first opening 1001. At this time, if the second opening 1002 is connected to the bottle body, the sample solution stored in the bottle body cannot flow directly from the first opening 1001 out of the bottle cap 100.

[0030] It should be noted that the size of the part of the sealing member 20 extending into the first opening 1001 matches the diameter of the first opening. That is, when the bottle cap 100 is in the closed state, the part of the connector 10 with the first opening 1001 abuts against the sealing member 20 extending into the first opening 1001.

[0031] like Figure 4 as well as Figure 5 As shown, when the seal 20 opens the first opening 1001, the bottle cap 100 is in the open state. When the bottle cap 100 is in the open state, the seal 20 is away from the first opening 1001. At this time, if the second opening 1002 is connected to the bottle body, the sample solution stored in the bottle body can flow out of the bottle cap 100 through the first opening 1001.

[0032] The sealing element 20 and the connecting element 10 can be detachably connected, or they can be movably connected. When the sealing element 20 and the connecting element 10 are detachably connected, they separate when the bottle cap 100 is open. When the sealing element 20 and the connecting element 10 are movably connected, the sealing element 20 rotates relative to the connecting element 10 from a first position to a second position when the bottle cap 100 is open, and the sealing element 20 and the connecting element 10 remain connected regardless of whether the sealing element 20 is in the first or second position.

[0033] And, as Figure 2 as well as Figure 5As shown, the connector 10 is provided with a first protrusion 101. When the bottle cap 100 is in the closed state, since at least a portion of the seal 20 extends into the first opening 1001, the first protrusion 101 on the connector 10 can compress the portion of the seal 20 inserted into the first opening 1001. Based on this, the provision of the first protrusion 101 can improve the tightness of the fit between the connector 10 and the seal 20. Thus, when the bottle cap 100 is in the closed state, the provision of the first protrusion 101 can enhance the interference fit between the connector 10 and the seal 20, thereby improving the tightness of the fit between the connector 10 and the seal 20. At this time, if the second opening 1002 is connected to the bottle body, the tightness of the fit between the sealing member 20 and the connecting member 10 is improved because the first protrusion 101 is provided on the connecting member 10. Therefore, the sample solution stored in the bottle body cannot flow out of the bottle cap 100 through the first opening 1001 and between the contact surface of the connecting member 10 and the contact surface of the sealing member 20 of the connecting member 10, thus improving the overall sealing performance of the bottle cap 100.

[0034] It is worth mentioning that, Figure 2 and Figure 5 In the illustrated bottle cap 100, the first protrusion 101 is provided on the connector 10. In other embodiments provided in this application, the first protrusion 101 may also be provided on the sealing member 20. In this way, when the bottle cap 100 is in the closed state, at least a portion of the sealing member 20 extends into the first opening 1001, and the first protrusion 101 is located on the portion of the sealing member 20 inserted into the first opening 1001. Thus, the first protrusion 101 can compress the connector 10 to close the first opening 1001, thereby improving the tightness of the fit between the connector 10 and the sealing member 20.

[0035] It is worth mentioning that when the bottle cap 100 is in the open state, since no part of the seal 20 extends into the first opening 1001, the first protrusion 101 will not compress the seal 20.

[0036] Specifically, such as Figure 2 and Figure 5 As shown, the seal 20 includes a first main body portion 21 and a first sealing portion 22.

[0037] The first main body portion 21 serves as a support portion for the seal 20, and is used to support the first sealing portion 22. The first sealing portion 22 is disposed on the first main body portion 21. One end of the first sealing portion 22 is connected to the first main body portion 21, and the other end of the first sealing portion 22 can extend into the first opening 1001.

[0038] In some embodiments of this application, the first sealing part 22 is a hollow columnar structure or a columnar structure, that is, the cross-sectional shape of the first sealing part 22 is annular or annular.

[0039] In another embodiment of this application, the first sealing part 22 is a solid columnar structure or a columnar structure, that is, the cross-section of the first sealing part 22 is circular or circular.

[0040] When the first protrusion 101 is provided on the seal 20, the first protrusion 101 may be specifically provided on the first sealing part 22. When the first sealing part 22 extends into the first opening 1001, the first protrusion 101 squeezes the connector 10.

[0041] Specifically, such as Figure 2 and Figure 5 As shown, the connector 10 includes a second main body 11, a first connecting part 12, and a second connecting part 13.

[0042] The second main body 11 is a support portion of the connector 10, and the second main body 11 is used to support the first connecting portion 12 and the second connecting portion 13. For example, the second main body 11 is an annular plate structure, the inner edge of the second main body 11 is connected to the first connecting portion 12, and the outer edge of the second main body 11 is connected to the second connecting portion 13.

[0043] Both the first connecting portion 12 and the second connecting portion 13 are hollow shells. The second end 12b of the first connecting portion 12 is inserted into the interior of the second connecting portion 13 from the first end 13a, while the first end 12a of the first connecting portion 12 is located outside the second connecting portion 13. Specifically, the outer edge of the second main body portion 11 is connected to the inner wall of the second connecting portion 13, and the inner edge of the second main body portion 11 is connected to the outer wall of the first connecting portion 12. The first connecting portion 12 is used to connect the sealing element 20, and the second connecting portion 13 is used to connect the bottle body.

[0044] Since the second main body 11 is connected to the first connecting part 12 and the second connecting part 13 respectively, and the first connecting part 12 and the second connecting part 13 are both hollow shells, the interior of the first connecting part 12, the interior of the second main body 11 and the interior of the second connecting part 13 are connected to form the receiving space 10c of the connector 10.

[0045] The first opening 1001 is located at the end of the first connecting portion 12 that does not extend into the second connecting portion 13, that is, the first opening 1001 is located at the first end 12a of the first connecting portion 12. It is worth mentioning that a third opening 1003 is also provided on the first connecting portion 12, and the third opening 1003 is located at the second end 12b of the first connecting portion 12, that is, the third opening 1003 is arranged opposite to the first opening 1001.

[0046] The second opening 1002 is located at the second end 13b of the second connecting portion 13, and the first end 13a and the second end 13b of the second connecting portion 13 are opposite ends. The second connecting portion 13 is also provided with a fourth opening 1004, which is located at the first end 13a of the second connecting portion 13, that is, the fourth opening is arranged opposite to the second opening 1002.

[0047] Based on the third opening 1003 and the fourth opening 1004, the inner cavity of the first connecting part 12 is connected to the inner cavity of the second connecting part 13, thereby connecting the second main body part 11, the first connecting part 12 and the second connecting part 13 to form the connector 10.

[0048] Among them, such as Figure 2 As shown, when the bottle cap 100 is in the closed state, the first main body 21 seals the first opening 1001, and the first sealing part 22 is inserted into the first connecting part 12. Furthermore, the first protrusion 101 is provided on the inner wall of the first connecting part 12, and the first protrusion 101 presses against the outer wall of the first sealing part 22 to close the first connecting part 12.

[0049] In other words, when the first protrusion 101 is provided on the connector 10, the first protrusion 101 can be provided on the first connecting portion 12. When the first sealing portion 22 of the seal 20 extends into the first opening 1001, the first protrusion 101 compresses the seal 20. Furthermore, please refer to... Figure 2 as well as Figure 5 As shown, the first protrusion 101 is arranged around the inner wall of the first connecting portion 12. That is, the first protrusion 101 is located on the inner wall of the first connecting portion 12, and the first protrusion 101 is arranged in a ring shape around the inner wall of the first connecting portion 12 in the circumferential direction. In this way, when the bottle cap 100 is in the closed state, the first protrusion 101 presses against the outer wall of the first sealing portion 22 in the radial direction of the first connecting portion 12. Thus, while the first body portion 21 closes the first opening 1001, the first connecting portion 12, the first protrusion 101, and the first sealing portion 22 cooperate to further seal the first opening 1001, preventing the sample solution from flowing out of the bottle cap 100 from between the contact surface of the first connecting portion 12 and the contact surface of the first sealing portion 22 of the first connecting portion 12.

[0050] Specifically, such as Figure 3 As shown, the first protrusion 101 includes a first sub-protrusion 1011 and a second sub-protrusion 1012.

[0051] The first sub-protrusion 1011 and the second sub-protrusion 1012 are continuous. The first sub-protrusion 1011 is located between the second sub-protrusion 1012 and the first end 12a of the first connecting portion 12. The first end 12a of the first connecting portion 12 is the end of the first connecting portion 12 away from the second connecting portion 13. That is, the first sub-protrusion 1011 and the second sub-protrusion 1012 are arranged sequentially along the direction from the first opening 1001 to the second opening 1002.

[0052] When a first protrusion 101 is provided on the inner wall of the first connecting portion 12, the first sub-protrusion 1011 has a first slope relative to the inner wall of the first connecting portion 12, and the second sub-protrusion 1012 has a second slope relative to the inner wall of the first connecting portion 12, the second slope being greater than the first slope.

[0053] In this embodiment, since the second slope of the second sub-protrusion 1012 is greater than the first slope of the first sub-protrusion 1011, the force generated by the first sub-protrusion 1011 pressing the first connecting portion 12 is less than the force generated by the second sub-protrusion 1012 pressing the first connecting portion 12. Therefore, when the operator closes the bottle cap provided in this application, the sealing member 22 first contacts the first sub-protrusion 1011, providing a pre-squeezed state for the first connecting portion 12 and the sealing member 22 to press together, which makes it easier for the operator to continue pressing down and improves the convenience of the operator to close the bottle cap 100. At the same time, since the sealing member 22 first experiences the pre-squeezed state and then fully squeezes, the sealing member 22 and the first connecting portion 12 fit more tightly, enhancing the sealing effect brought about by the compression of the two.

[0054] It is worth mentioning that in some other embodiments provided in this application, the first protrusion 101 may also be arranged around the outer wall of the first sealing portion 22. That is, the first protrusion 101 is located on the outer wall of the first sealing portion 22, and the first protrusion 101 is arranged in a ring shape around the outside of the first sealing portion 22 in the circumferential direction. In this way, when the bottle cap 100 is in the closed state, the first protrusion 101 presses against the inner wall of the first connecting portion 12 in the radial direction of the first sealing portion 22. Thus, while the first body portion 21 closes the first opening 1001, the first connecting portion 12, the first protrusion 101, and the first sealing portion 22 cooperate to further seal the first opening 1001, preventing the sample solution from flowing out of the bottle cap 100 from between the contact surface of the first connecting portion 12 of the first sealing portion 22 and the contact surface of the first sealing portion 22 of the first connecting portion 12.

[0055] Specifically, when a first protrusion 101 is provided on the outer wall of the first sealing portion 22, the first protrusion 101 may also include a first sub-protrusion 1011 and a second sub-protrusion 1012. The first sub-protrusion 1011 and the second sub-protrusion 1012 are continuous, and the first sub-protrusion 1011 is located on the side of the second sub-protrusion 1012 near the first end 12a of the first connecting portion 12.

[0056] The first sub-protrusion 1011 has a third slope relative to the outer wall of the first sealing part 22, and the second sub-protrusion 1012 has a fourth slope relative to the outer wall of the first sealing part 22, the fourth slope being greater than the third slope.

[0057] In this embodiment, since the fourth slope of the second sub-protrusion 1012 is greater than the third slope of the first sub-protrusion 1011, the force generated by the first sub-protrusion 1011 pressing the first sealing part 22 is less than the force generated by the second sub-protrusion 1012 pressing the first sealing part 22, thereby improving the convenience for the operator to close the bottle cap 100.

[0058] Furthermore, there are multiple first protrusions 101 arranged around the inner wall of the first connecting portion 12, and the multiple first protrusions 101 are spaced apart along the axial direction of the first connecting portion 12.

[0059] Based on the fact that multiple first protrusions 101 are spaced apart along the axial direction of the first connecting portion 12, it is ensured that the first connecting portion 12 forms an interference fit with the first sealing portion 22 through the multiple first protrusions 101, thereby further preventing the sample solution from flowing out of the bottle cap 100 through the first opening 1001 between the contact surface of the first sealing portion 22 of the first connecting portion 12 and the contact surface of the first connecting portion 12 of the first sealing portion 22.

[0060] Correspondingly, in some other embodiments provided in this application, there may be multiple first protrusions 101 surrounding the outer wall of the first sealing portion 22, and the multiple first protrusions 101 are spaced apart along the axial direction of the first connecting portion 12.

[0061] Based on the fact that multiple first protrusions 101 are spaced apart along the axial direction of the first sealing portion 22, it is ensured that the first connecting portion 12 forms an interference fit with the first sealing portion 22 through the multiple first protrusions 101, thereby further preventing the sample solution from flowing out of the bottle cap 100 through the first opening 1001 between the contact surface of the first connecting portion 12 of the first sealing portion 22 and the contact surface of the first connecting portion 12 of the first sealing portion 22.

[0062] For further information, please refer to [link / reference]. Figure 5 In some embodiments provided in this application, the first connecting portion 12 includes a first connecting sub-portion 121 and a second connecting sub-portion 122.

[0063] The first connecting part 121 is formed by extending from the inner edge of the second main body part 11 in a direction away from the second opening 1002.

[0064] The second connecting part 122 is formed by extending from the inner edge of the second main body part 11 toward the direction close to the second opening 1002.

[0065] In this configuration, with the first protrusion 101 annularly disposed on the inner wall of the first connecting portion 12, the first protrusion 101 is also disposed on the first connecting sub-portion 121. Therefore, when the bottle cap 100 is in the closed state, the end of the first connecting sub-portion 121 away from the second main body portion 11 abuts against the first main body portion 21, thereby blocking the first opening 1001 along the axial direction of the connector 10, thus improving the sealing performance of the first opening 1001. At this time, the first protrusion 101 compresses the outer wall of the first sealing portion 22 radially along the first connecting portion 12.

[0066] For further information, please refer to [link / reference]. Figure 5 The angle α between the first connecting part 121 and the second main body 11 is an obtuse angle. That is, while the first connecting part 121 extends towards the first opening 1001, it also retracts radially towards its axial direction. This allows the first sealing part 22 to be inserted into the first connecting part 121 through the first opening 1001, ensuring a tight fit between the first protrusion 101 and the first sealing part 22. This prevents the sample solution stored in the bottle from evaporating or leaking through the first opening 1001 when the bottle cap 100 is connected to the bottle body.

[0067] The included angle between the first connecting sub-part 121 and the second main body part 11 is greater than 90 degrees and less than or equal to 95 degrees. Specifically, this included angle can be 90.5 degrees, 91 degrees, 91.5 degrees, 92 degrees, 92.5 degrees, 93 degrees, 93.5 degrees, 94 degrees, 94.5 degrees, or 95 degrees.

[0068] Furthermore, such as Figure 2 , Figure 4 as well as Figure 5As shown, in some embodiments provided in this application, the seal 20 further includes a second sealing portion 23. The second sealing portion 23 is disposed on the first main body portion 21, and the second sealing portion 23 and the first sealing portion 22 are disposed on the same surface of the first main body portion 21. The second sealing portion 23 extends along the outer edge of the first main body portion 21 such that the cross-sectional shape of the second sealing portion 23 is arc-shaped, circular, or nearly circular. When the bottle cap 100 is in the closed state, the end of the second sealing portion 23 away from the first main body portion 21 abuts against the second main body portion 11. The second sealing portion 23 can isolate the interior and exterior of the bottle cap 100, preventing the exterior of the bottle cap 100 from contaminating the interior of the bottle cap 100 and improving the sealing performance of the bottle cap 100.

[0069] For further information, please refer to [link / reference]. Figure 2 as well as Figure 5 In some embodiments provided in this application, a boss 211 is formed on the first main body 21 extending radially outward from the connection between the first main body 21 and the second sealing part 23. Based on the setting of the boss 211, it is convenient for the operator to touch the boss 211 to switch the bottle cap 100 between the open state and the closed state.

[0070] Furthermore, such as Figures 4 to 7 As shown, the first main body 21 and the second main body 11 are rotatably connected.

[0071] For example, the first main body 21 and the second main body 11 can be connected by a pivot, so that when the second main body 11 rotates relative to the first main body 21, the seal 20 rotates relative to the connector 10.

[0072] For example, the first main body portion 21 and the second main body portion 11 can also be rotatably connected by a rotating belt. Figures 4 to 7 As shown, the first end of the rotating belt 40 is connected to the first main body 21, and the last end of the rotating belt 40 is connected to the second main body 11. The last end of the rotating belt can rotate relative to the first end of the rotating belt. When the seal 20 rotates relative to the connector 10, the first end of the rotating belt rotates with the rotation of the seal 20, while ensuring that the seal 20 does not detach from the connector 10.

[0073] For further information, please refer to [link / reference]. Figures 4 to 7 As shown, the bottle cap 100 also includes a rotation limiting assembly 30. The rotation limiting assembly 30 includes a first rotation limiting part 31 and a second rotation limiting part 32.

[0074] The first rotation limiting part 31 is provided on the second main body part 11, and the first rotation limiting part 31 is located on the side of the second main body part 11 away from the second connecting part 13. The second rotation limiting part 32 is provided on the first main body part 21.

[0075] When the bottle cap 100 is in the open state, the second rotation limiting part 32 abuts against the first rotation limiting part 31, thereby maintaining the included angle between the first main body part 21 and the second main body part 11 at a right angle or an acute angle. Specifically, as shown in the figure... Figure 4 As shown, the first rotation limiting part 31 is configured to form a limiting boss, and the end face of the limiting boss abuts against the second rotation limiting part 32.

[0076] For example, such as Figure 4 as well as Figure 5 As shown, the included angle between the first main body portion 21 and the second main body portion 11 is a right angle.

[0077] Based on the rotation limiting component 30, when the cap 100 is in the open state, the rotation limiting component maintains the rotation angle of the sealing member 20 relative to the connecting member 10 at a right angle or an acute angle. This facilitates the operator to feed the sample solution into the bottle body connected to the cap 100 through the cap 100, and to remove the sample solution through the cap 100. For example, when multiple sample bottles 300 equipped with the cap 100 provided in this embodiment are arranged in an array in the sampling tank, since the rotation angle between the limiting component and the connecting member 10 is maintained at a right angle or an acute angle when the cap 100 is in the open state, the limiting component of the cap 100 in the current column will not block the first opening 1001 of the cap 100 in the next column, and the limiting component of the cap 100 in the current row will not block the first opening 1001 of the cap 100 in the next row. This facilitates the operator to transport or obtain sample solutions from sample bottles 300 in the same column or row in batches.

[0078] Furthermore, the second rotation limiting part 32 and the first sealing part 22 are located on the same side of the first main body part 21, so that the second rotation limiting part 32 and the first sealing part 22 can be formed simultaneously on the first main body part 21.

[0079] Furthermore, such as Figure 2 , Figure 5 as well as Figure 7 As shown, a second protrusion 102 is provided on the inner wall of the second connecting portion 13. A plurality of second protrusions 102 are located at the first end 13a of the second connecting portion 13, and are spaced apart circumferentially along the second main body portion 11. The first end 13a of the second connecting portion 13 is the end of the second connecting portion 13 closest to the second main body portion 11.

[0080] Based on the second protrusion 102 provided on the inner wall of the second connecting part 13, when the second opening 1002 is connected to the bottle body, the second protrusion 102 squeezes the bottle body so that the bottle body is clamped between the second connecting part 122 and the second connecting part 13, thereby realizing the interference fit connection between the connector 10 and the bottle body.

[0081] Furthermore, the second protrusion 102 extends parallel to the axial direction of the second connecting portion 13. For example... Figure 5 As shown, the second protrusion 102 includes a third sub-protrusion 1021 and a fourth sub-protrusion 1022. That is, the extending directions of both the third sub-protrusion 1021 and the fourth sub-protrusion 1022 are parallel to the axial direction of the second connecting portion. The fourth sub-protrusion 1022 is continuous with the third sub-protrusion 1021 and is located on the side of the third sub-protrusion 1021 closest to the second main body 11, i.e., between the third sub-protrusion 1021 and the first end 13a of the second connecting portion 13. In other words, the fourth and third sub-protrusions are sequentially arranged along the direction from the first opening 1001 to the second opening 1002.

[0082] The third sub-protrusion 1021 has a first thickness relative to the inner wall of the second connecting portion 13, and the fourth sub-protrusion 1022 has a second thickness relative to the inner wall of the second connecting portion 13. From the direction from the third sub-protrusion 1021 to the fourth sub-protrusion 1022, the thickness value of the first thickness increases to the thickness value of the second thickness, and the thickness value of the second thickness is a constant.

[0083] Based on the setting of the third sub-protrusion 1021, during the process of the bottle extending into the second opening 1002, the third sub-protrusion 1021 first applies a force generated by compression to the bottle, and this force increases as the bottle extends into the second opening 1002. Thus, the more the bottle extends into the second opening 1002, the tighter the second connecting part 13 and the second connecting part 122 clamp the bottle.

[0084] Furthermore, such as Figure 2 as well as Figure 4 As shown, a third protrusion 103 is also provided on the inner wall of the second connecting portion 13. Multiple third protrusions 103 are located on the side of the second protrusion 102 away from the second main body portion 11. These third protrusions 103 are spaced apart circumferentially along the second connecting portion 13, and their extending directions are parallel to the circumferential direction of the second connecting portion 13. The third protrusions 103 are used to restrict the axial movement of the bottle body, thereby improving the connection stability between the bottle body and the cap 100.

[0085] It is worth mentioning that in some other embodiments provided in this application, a plurality of third protrusions 103 are continuously arranged along the circumference of the second connection 13, so that for any two adjacent third protrusions 103, the head end of one is connected to the tail end of the other.

[0086] In a second aspect of this application, a sample bottle 300 is also provided. (As...) Figure 8 as well as Figure 9As shown, the sample bottle 300 includes the bottle cap 100 provided in any of the foregoing embodiments, and the bottle body 200, which is connected to the second opening 1002.

[0087] Specifically, the bottle body 200 includes a bottom 210 and a side portion 220. The side portion 220 is a hollow shell with an open end 220a and a closed end disposed opposite to each other. The bottom 210 is used to close the closed end, and the closed end is connected to the bottom 210 to form a sample storage chamber 200a. Furthermore, when the bottle body 200 is connected to the second opening 1002, the open end 220a extends into the connector 10 from the second opening 1002. At this time, if the cap 100 is in the closed state, the cap 100 cooperates with the bottle body 200 to isolate the interior of the sample bottle 300 from the exterior of the sample bottle 300, preventing the sample solution stored in the bottle body 200 from leaking to the exterior of the sample bottle 300 from the first opening 1001 of the cap 100.

[0088] Furthermore, if a third protrusion 103 is provided on the inner wall of the second connecting portion 13 of the connector 10, a corresponding fourth protrusion 201 is also provided on the outer wall of the bottle body 200. The fourth protrusion 201 is arranged circumferentially on the outer wall of the bottle body 200.

[0089] Based on the fourth protrusion 201, the bottle body 200 and the second connecting part 13 of the connector 10 are connected by an interference fit, thereby realizing a detachable connection between the bottle body 200 and the connector 10. When the bottle body 200 and the connector 10 are connected, the sealing performance between the second connecting part 13 and the bottle body 200 is improved, further reducing the possibility of the sample solution stored in the bottle body 200 leaking from the second opening 1002 of the bottle cap 100 to the outside of the sample bottle 300.

[0090] Furthermore, when the bottle body 200 is connected to the bottle cap 100, the fourth protrusion 201 is located on the side of the third protrusion 103 near the second main body 11. In this way, the third protrusion 103 can provide some support for the fourth protrusion 201 and prevent the bottle body from falling off the connector 10 along the axial direction of the bottle body.

[0091] like Figure 9 As shown, the longitudinal cross-sectional shape of the bottle bottom 210 is an inverted cone shape, so that the sample solution inside the bottle body 200 is relatively concentrated in the middle area of ​​the bottom of the bottle body 200, which is conducive to completely removing the sample solution inside the bottle body 200 and avoiding omission.

[0092] It is worth mentioning that the sample bottle 300 provided in this application can be used to store blood samples, reagent samples, as well as quality control products, standards, etc., and this application does not limit it in this regard.

[0093] Of course, this application may have other various embodiments. Without departing from the spirit and essential points of this application, those skilled in the art can make various corresponding changes and modifications based on this application, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
