Abstract

This invention relates to a cap for a microbial culture bottle, comprising: a main body having a top, a connecting portion, and a sleeve portion connected in sequence, the inner wall of the sleeve portion having an internal thread section; an opening located at the top and penetrating the main body; an extending rib extending from the periphery of the top in a direction opposite to the sleeve portion; a mounting rib extending from the periphery of the opening in a direction opposite to the sleeve portion; a locking rib extending from the inner wall of the top in a direction towards the sleeve portion; and a plurality of drainage holes, each drainage hole located in the main body and penetrating the top and the connecting portion respectively; wherein, the internal thread section is used to move and engage with the external thread section of the bottle body to increase sealing and engagement stability. At the same time, the drainage holes form a stable gas flow path and drain internal moisture to avoid water vapor retention affecting the breathability.

Claims

1. A cap for a microbial culture bottle, comprising: a main body having a top, a connecting portion, and a sleeve portion, the two ends of the connecting portion being connected to the top and the sleeve portion respectively, the inner wall surface of the sleeve portion having an internal thread section; an opening disposed at the top and penetrating the main body; an extending rib extending from the periphery of the top in a direction opposite to the sleeve portion; a mounting rib extending from the periphery of the opening in a direction opposite to the sleeve portion; a locking rib extending from the inner wall surface of the top in a direction towards the sleeve portion; and a plurality of drain holes, each drain hole being disposed at the main body and each drain hole penetrating the top and the connecting portion; wherein... The internal thread section is used to move and connect with the external thread section of a bottle body.

2. The culture bottle cap as described in claim 1, wherein, The height of the extended rib protrusion is higher than the height of the mounting rib protrusion.

3. The culture bottle cap as described in claim 1, wherein, A separate fabric piece is provided, which is partially fused to the mounting rib and covers the opening.

4. The culture bottle cap as described in claim 1, wherein, The drainage holes are arranged at intervals, and each drainage hole further has an inclined surface, which slopes from one end near the opening toward one end near the top periphery.

5. The culture bottle cap as described in claim 1, wherein, The card rib and the inner wall of the joint further form an engagement area.

6. A cap for a microbial culture bottle, comprising: a main body having a top, a connecting portion, and a sleeve portion, the two ends of the connecting portion being connected to the top and the sleeve portion respectively, the inner wall surface of the sleeve portion having an internal thread section; an opening disposed at the top and penetrating the main body; a plurality of extending ribs, each extending from the periphery of the top in a direction opposite to the sleeve portion, and each extending rib forming a venting area; a mounting rib, extending from the periphery of the opening in a direction opposite to the sleeve portion; a locking rib, extending from the inner wall surface of the top in a direction towards the sleeve portion; and a plurality of drain holes, each drain hole disposed at the main body and penetrating the top and the connecting portion respectively; wherein... The internal thread section is used to move and connect with the external thread section of a bottle body.

7. The culture bottle cap as described in claim 6, wherein, The height of the extended rib protrusion is higher than the height of the mounting rib protrusion.

8. The culture bottle cap as described in claim 6, wherein, A separate fabric piece is provided, which is partially fused to the mounting rib and covers the opening.

9. The culture bottle cap as described in claim 6, wherein, The drainage holes are arranged at intervals, and each drainage hole further has an inclined surface, which slopes from one end near the opening toward one end near the top periphery.

10. The culture bottle cap as described in claim 6, wherein, Each ventilation zone is arc-shaped on one side of the perimeter of the top.

11. The culture bottle cap as described in claim 6, wherein, The card rib and the inner wall of the joint further form an engagement area.
