Description

Technical Field

[0001] The invention relates to a sealing cover and a container device, belonging to the technical field of biomedical consumables. Background Art

[0002] Biomedical consumables play an extremely important role in the fields of biology, testing, diagnosis and medicine. Taking cryotubes as an example, cryotubes include containers and sealing covers, which are mainly used to place cells or tissues in containers, and then seal the containers with sealing covers and place them in liquid nitrogen for cryopreservation. In this process, the sealing cover needs to seal the container to prevent the cells or tissues in the container from flowing out of the container, or liquid nitrogen from entering the container, causing failure and impact of cells or tissues. In addition, if liquid nitrogen enters the container, placing the cryotube in a room temperature environment will also cause problems such as container explosion.

[0003] In the prior art, a sealing gasket that matches the opening of the container is generally placed in the sealing cover to achieve the best effect, but this increases the production cost and manufacturing cost, which is relatively inconvenient; there is also a method of using two materials to form an integral body, but the mold and product costs are significantly increased. If the sealing method is adopted in which a sealing convex ring provided on the inner wall of the top of the sealing cover is tightly matched with the inner side wall of the container opening to achieve sealing, the sealing effect is poor and not ideal, which leads to a low survival rate of the preserved cells or tissues. Summary of the invention

[0004] The object of the present invention is to provide a sealing cover and a container device, which can reduce production costs while having a good sealing effect.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a sealing cover for docking with a container, the container having an opening, the sealing cover comprising a cover body, a first sealing component arranged at the end of the cover body and abutting against the container to prevent external media from entering the container, and a second sealing component arranged on the top inner wall of the cover body and cooperating with the opening to prevent liquid in the container from leaking out, the first sealing component and the second sealing component are integrally formed with the cover body and are made of the same material.

[0006] Furthermore, the first sealing assembly includes an elastic abutment; when the sealing cover is docked with the container, the elastic abutment abuts against the outer wall of the container.

[0007] Furthermore, the elastic supporting member includes a bending portion connected to the end of the cover body and a supporting portion connected to the bending portion, and the bending portion is bent under the action of an external force so that the supporting portion is in contact with the outer wall of the container.

[0008] Furthermore, the thickness of the bending portion is smaller than the thickness of the supporting portion.

[0021] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] See also Figure 1 A container device in a preferred embodiment of the present invention is mainly used for biomedical testing. The container device can be a freezing tube, a centrifuge tube, a centrifuge bottle, a reagent storage tube, a virus collection tube, a reagent bottle, a serum bottle, a culture medium bottle, etc., which is not specifically limited here and depends on the actual situation.

[0023] The container device includes a container 2 and a sealing cover 1 that covers the container 2 to seal the container 2. Taking a cryopreservation tube as an example, the container 2 is a tube body 21 for placing cells or tissues, and the sealing cover 1 cooperates with the tube body 21 to seal the tube body 21. The tube body 21 has an opening 22. In this embodiment, the tube body 21 has a first body part 211 for placing reagents and a second body part 212 that is connected to the first body part 211. The diameter of the first body part 211 is greater than the diameter of the second body part 212 to form a boss 23, and the opening 22 is set at one end of the second body part 212. The first body part 211 and the second body part 212 are integrally formed. Of course, the first body part 211 and the second body part 212 can also be separately set and then connected by welding, bonding, etc., but its manufacturing process is complicated, the production cycle is long, and the cost is increased. In other embodiments, the tube body 21 may also include only a main body portion, and the sealing cover 1 and the main body portion may be supported by interference fit, which is not specifically limited here and depends on actual conditions.

[0024] Please combine Figures 2 to 4 The sealing cover 1 includes a cover body 11, a first sealing component 12 disposed at the end of the cover body 11 and abutting against the container 2 to prevent external media from entering the container 2, and a second sealing component 13 disposed on the top inner wall of the cover body 11 and cooperating with the opening 22 to prevent the liquid in the container 2 from leaking out. By providing the first sealing component 12 and the second sealing component 13, a two-way sealing of the container 2 can be achieved, thereby improving the overall sealing efficiency of the container device. In this embodiment, the first sealing component 12 and the second sealing component 13 are integrally formed with the cover body 11 and are made of the same material. The purpose of such a setting is to simplify the production process, shorten the production cycle, reduce the production cost, and be quick and convenient.

[0025] The first sealing assembly 12 includes an elastic abutting member 121, which is bent toward the inside of the cover body 11 and forms an angle with the cover body 11, and the angle range is 10-60°. Of course, the angle range can also be other, which is not specifically limited here, and depends on the actual situation. When the sealing cover 1 is docked with the container 2, the elastic abutting member 121 abuts against the outer wall of the container 2. Specifically, the elastic abutting member 121 includes a bending portion 1211 connected to the end of the cover body 11 and a supporting portion 1212 connected to the bending portion 1211, and the bending portion 1211 is bent under the action of an external force so that the supporting portion 1212 abuts against the outer wall of the container 2. That is, when the sealing cover 1 is covered on the opening 22, the bending portion 1211 abuts against the boss 23 after bending, and the supporting portion 1212 abuts against the outer wall of the tube body 21 to achieve sealing. In this embodiment, the thickness of the bending portion 1211 is smaller than the thickness of the supporting portion 1212 , so that the bending portion 1211 is easily bent under the action of external force.

[0026] The first sealing assembly 12 further includes at least one first sealing protrusion 122 disposed on the inner wall of the cover body 11 and disposed near the elastic abutment 121, and the first sealing protrusion 122 is formed by protruding outward from the inner wall surface of the cover body 11. The number of the first sealing protrusions 122 is determined according to actual conditions and is not specifically limited here. In order to enhance the sealing performance, in this embodiment, the first sealing protrusion 122 is a continuous convex ring. When the cover body 11 and the tube body 21 are covered, the first sealing protrusion 122 and the outer wall of the tube body 21 are interference fit. The cover body is also provided with a thread, and correspondingly, the outer wall of the tube body 21 is also provided with a corresponding thread, that is, the tube body 21 and the cover body 11 are threadedly connected. The threaded connection method is a conventional means, such as the thread shape is generally triangular, rectangular or arc-shaped, which is continuously or discontinuously arranged, and the general thread has a small angle at the beginning and a large angle at the outside, which is conducive to the mutual cooperation of the threaded connection parts, and will not be repeated here. It is worth noting that in this embodiment, the thread on the cover 11 is a forced release structure, that is, during injection molding, the cover 11 can be directly removed from the mold, rather than rotating the cover 11 to remove it from the mold. The purpose of using a forced release structure is to reduce mold costs and shorten production cycles.

[0027] The second sealing assembly 13 includes at least one sealing convex ring 131 disposed on the top inner wall of the cover body 11, and the sealing convex ring 131 abuts against the top of the opening 22 to achieve sealing. Accordingly, the number of the sealing convex rings 131 is determined according to actual conditions and is not specifically limited here. When the sealing cover 1 is covered with the container 2, the sealing convex ring 131 is interference-fitted with the top of the opening 22 to achieve sealing.

[0028] The second sealing assembly 13 also includes an elastic sealing arm 132 disposed on one side of the sealing convex ring 131 and abutting against the side wall of the opening 22. A dodge groove is formed between the elastic sealing arm 132 and the side of the cover body 11 to allow the elastic sealing arm 132 to dodge under the movement of the opening 22. When the sealing cover 1 is connected with the tube body 21, the elastic sealing arm 132 is pushed to one side of the dodge groove under the force of the tube body 21 and clamped with the outer wall of the opening 22 to achieve secondary sealing. In this embodiment, the elastic sealing arm 132 has a contact surface that contacts and seals with the top of the opening 22, and the contact surface is an inner concave arc surface that cooperates with the outer wall of the opening 22 to enhance the sealing performance.

[0029] The second sealing assembly 13 also includes at least one second sealing protrusion 133 disposed on the inner wall of the cover body 11 and having an interference fit with the inner wall of the opening 22. The number of the second sealing protrusions 133 is determined according to actual conditions and is not specifically limited here. The second sealing protrusion 133 includes a guide portion 1331 connected to the top inner wall of the cover body 11 and used for guiding, and a sealing portion 1332 protruding outward from the surface of one side of the guide portion 1331 to form a contact seal with the inner wall of the opening 22. The guide portion 1331 is used to allow the sealing portion 1332 to enter the inner wall of the opening 22 to contact and seal with the inner wall, thereby achieving the sealing of the sealing cover 1 and the opening 22.

[0030] The sealing cover 1 and / or the container 2 are provided with a laser mark formed by laser marking. The laser mark is formed by laser printing and will not cause pollution to the container device, and will not affect the accuracy of the test result. The laser mark can be set on the outside or inside of the sealing cover 1, or on the bottom or other positions of the tube body 21 as needed, which is not specifically limited here and depends on the actual situation. The laser mark can be a QR code, a bar code, a product batch number, a serial number, etc., which depends on the actual situation and is not specifically limited here. The user can use the laser mark to identify the cells or tissues in the container 2, and to trace and record the product.

[0031] In summary: by providing a first sealing component 12 on the cover body 11 for preventing external media from entering the container 2 and a second sealing component 13 for preventing liquid in the container 2 from leaking out, a two-way sealing is achieved, thereby improving the overall sealing efficiency of the sealing cover 1; by forming the first sealing component 12 and the second sealing component 13 integrally with the cover body 11 and using the same material, the manufacturing cost of the sealing cover 1 is reduced and the production efficiency of the sealing cover 1 is improved.
