Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are intended to be inclusive and mean, for example, that they may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The inventor finds that: the sealing structure of the tube cap container is relatively mature, but the prior sealing structure is mostly only used for beverage or daily chemical liquid products, and the sealing performance of the products is not high as that of medical products. The sample preservation solution product is required to be used for loading viruses, and the requirement on sealing performance is extremely high, so that the requirement of the product cannot be met by a common sealing structure.
The present application provides an embodiment of a tube sealing structure for a sample preservation solution, and specifically refers to fig. 1 and 4.
The body seal structure of the sample preservation solution in this embodiment includes: body 2 and install pipe cap 1 on body 2, the inside sunken annular concave part 11 that is formed with of pipe cap 1 top surface, one side that concave part 11 is close to body 2 is provided with sealing ring 3.
It should be noted that: this seal structure is through at the inside concave type portion 11 that caves in of 1 top surface of pipe cap formation ring form to be provided with sealing ring 3 in one side that concave type portion 11 is close to body 2, can effectively increase sealing ring 3's elasticity, make concave type portion 11 and 2 inside walls of body closely laminate together, and then effectively improve the sealing performance between concave type portion 11 and the body 2, thereby protection medical personnel's safety.
The above is a first embodiment of the tubular sealing structure for a sample preservation fluid provided in the present application, and the following is a second embodiment of the tubular sealing structure for a sample preservation fluid provided in the present application, specifically referring to fig. 1 to 4.
The body seal structure of the sample preservation solution in this embodiment includes: body 2 and install pipe cap 1 on body 2, the inside sunken annular concave part 11 that is formed with of pipe cap 1 top surface, one side that concave part 11 is close to body 2 is provided with sealing ring 3.
It will be appreciated that the wall thickness of the female part 11 may be made thin in order to further increase the resilience of the sealing ring 3.
