In this embodiment, referring to fig. 2 and 3, the first cover 1 and the second cover 2 are connected by internal and external threads.
Referring to fig. 1 to 6, the first cover 1 is hollow to form a storage chamber 11 for storing a microorganism detection reagent, the storage chamber 11 has a chamber bottom 111 and a chamber top 112, in this embodiment, the storage chamber 11 may be cylindrical, the chamber bottom 111 is a closed structure, and the chamber top 112 is an open structure. Referring to fig. 2 and 6, the edge of the cavity bottom 111 is provided with crater-like pits 1111.
Referring to fig. 1-3, 7 and 8, a mounting hole (not shown) is formed in the cover layer 21 of the second cover 2, and a puncturing member 22 is inserted into the mounting hole. Specifically, one end of the piercing member 22 has a piercing part 221, and the other end of the piercing member 22 passes through the mounting hole and extends out of the cover layer 21 to form a pressing boss 222. Pressing the pressing boss 222 by an external force moves the piercing member 22 in a direction parallel to the axial direction of the storage chamber 11 so that the piercing part 221 can pierce the chamber bottom 111, thereby allowing the microorganism detection reagent to flow out from the chamber bottom 111. As an alternative that is easily conceivable by a person skilled in the art, the cover layer may not be provided with the mounting hole, and the puncturing element 21 may be fixedly connected to the side of the cover layer 21 facing the storage chamber 11 and arranged coaxially with the second cover 2, so that puncturing the chamber bottom 111 can be achieved by moving the second cover 2 such that the puncturing element 21 is moved in a direction parallel to the axial direction of the storage chamber 111.
Referring to fig. 2 and 8, the pressing boss 222 includes an extending section 2221 and a pressing end 2222 connected to each other, the pressing end 2222 has a reverse tapered structure, the minor diameter end of the reverse taper is connected to the extending section 2221, when the pressing end 2,222 is pressed by an external force, the extending section 2221 is movable in the axial direction of the storage cavity 11 to extend into the storage cavity 11, and the pressing end 2222 is movable along with the extending section 2221 into the mounting hole and seals the mounting hole/cover surface layer by the reverse tapered structure thereof, thereby sealing the storage cavity 11.
Referring to fig. 8, in the present embodiment, the puncturing member 22 has a long puncturing portion 221 which can puncture the cavity bottom 111 in a point-to-point manner in accordance with the position of the crater-like crater 1111 formed at the edge of the cavity bottom 111, and the wall thickness of the edge of the cavity bottom 111 becomes thinner due to the crater 1111, so that puncturing can be performed more easily and puncturing can be performed more easily. Referring to fig. 2, 7 and 8, the puncturing member 22 may have a hollow cylindrical structure, and may further have a reinforcing rib 223 formed therein.
The second cover 2 can be sealingly connected to the chamber top 112 of the storage chamber 11. in particular, the second cover 2 comprises a connecting member 23 sealingly connecting the piercing member 22 to the mounting hole. The connecting element 23 can be arranged on the side of the covering surface layer 21 facing the storage chamber 11, for example, a sealing gasket or a sealing ring sleeved on the piercing element 22, or can be arranged on the side of the covering surface layer 21 facing away from the storage chamber 11, for example, a sealing ring embedded in the mounting hole and capable of being disassembled and assembled, or can be designed integrally with the covering surface layer 21 and the piercing element 22. In this embodiment, referring to fig. 7 and 8, the connecting member 23 is integrally connected to the cover 21 and the piercing member 22, and the connecting member 23 is flush with the upper surface of the cover 21, but the thickness of the connecting member 23 is smaller than that of the cover 21, so that the crater-like second recesses 211 are formed below the connecting member 23. When the pressing boss 222 is pressed by an external force, the puncturing member 22 moves in the storage chamber 11 along a direction parallel to the axial direction of the storage chamber 111, and the connecting member 23 is deformed or broken.
The exterior of the storage chamber 11 may further be connected to a filter device 3, which filter device 3 may be a funnel, as shown in fig. 1-3. The filtering device 3 is sleeved outside the cavity bottom 111 and is provided with a filtering hole 31, so that the detection reagent flowing out from the cavity bottom can be filtered or screened, and large particles or other impurities and the like in the detection reagent can be separated.
The utility model also provides a microbial cultivation detects bottle, it has embodiment 1 the bottle lid. Specifically, as shown in fig. 1 to 3, the filtering device 3 is provided with a blocking edge 32, which is sleeved outside the cavity bottom 111 and is abutted/hung on the bottle mouth of the bottle body 4 by the blocking edge 32, the bottle neck of the bottle body is provided with an external thread, the first cover body 1 is provided with an internal thread matched with the external thread of the bottle neck, and when the bottle body 4 is tightly screwed with the bottle cap (the first cover body 1), the blocking edge 32 of the filtering device is clamped at the top of the bottle mouth and the first cover body 1 and can form a sealing structure.
The utility model provides a microbial cultivation detects bottle use as follows:
firstly, microorganism culture bacteria can be placed in the bottle body 4 for culture, then the filtering device 3 and the first cover body 2 are sequentially connected, the first cover body 1 is connected with the bottle body 4 in a screwing manner, and the cavity bottom 111 of the storage cavity 11 in the first cover body 1 is a sealed structure which is not punctured or punctured;
secondly, adding a certain amount of microorganism detection reagent into the storage cavity 11 of the first cover body 1, and screwing the second cover body 2 and the first cover body 1 through internal and external matched threads;
finally, when the microorganisms in the bottle 4 need to be detected, the pressing boss 222 is pressed, the pressing boss 222 moves to drive the whole puncturing part 22 to move along the direction parallel to the axial direction of the storage cavity 11, and then the cavity bottom 111 is punctured (at this time, the inverted cone-shaped structure of the pressing end 2222 seals the mounting hole/cover layer), so that the microorganism detection reagent in the storage cavity 11 flows out from the cavity bottom 111, enters the filtering device 3 to be filtered and separated, and then enters the bottle 4 to be detected.
The above embodiments are only used for explaining the technical solution of the present invention and not for limiting the same, and although the above embodiments are specific to the present invention, it should be understood by those skilled in the art that the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the present invention, which should be covered by the claims of the present invention.
