Abstract

In some examples, an instrument closure may include an instrument closure retainer to retain the instrument closure onto a container. The instrument closure may further include a sensor retainer including a plurality of apertures for transfer or removal of material, respectively, into or from the container. The sensor retainer may further include a sensor mount to retain a sensor.

First claim

What is claimed is:

1. An instrument closure comprising:
an instrument closure retainer to retain the instrument closure onto a container; and
a sensor retainer including
a plurality of apertures for transfer or removal of material, respectively, into or from the container; and
a sensor mount to retain a sensor,
wherein the sensor mount is configured to extend along and be coaxial with a central longitudinal axis of the sensor retainer beyond the instrument closure retainer into the container or extend beyond the instrument closure retainer away from the container, and
wherein the sensor mount is substantially hollow to enable electrical connection to the sensor from an open end of the sensor mount that is open to environment.

2. The instrument closure according to claim 1 ,
wherein the sensor retainer includes a first face that is positioned towards the container and a second opposite face that is positioned away from the container when the instrument closure is retained onto the container, and
wherein the sensor mount is positioned on the first face.

3. The instrument closure according to claim 1 , wherein the sensor mount includes a cylindrical cross-section to retain a complementary shaped sensor substantially within the sensor mount.

4. The instrument closure according to claim 1 , wherein the sensor mount includes at least two sensor mount structures that form a partial cylindrical cross-section to retain a cylindrical sensor substantially within the sensor mount.

5. The instrument closure according to claim 1 ,
wherein the sensor retainer includes a first face that is positioned towards the container and a second opposite face that is positioned away from the container when the instrument closure is retained onto the container, and
wherein the sensor mount is positioned on the second face.

6. The instrument closure according to claim 5 , wherein the sensor includes a floater that is at least partially disposed thorough the sensor retainer to measure a level of fluid in the container.

7. The instrument closure according to claim 5 , wherein the sensor mount is dimensioned to maintain the sensor at a predetermined distance from the container.

8. The instrument closure according to claim 1 ,
wherein at least one aperture of the plurality of apertures is internally threaded to retain an insert that is at least partially externally threaded.

9. The instrument closure according to claim 1 , wherein the instrument closure retainer includes a knurled outer surface to facilitate gripping of the instrument closure retainer.

10. The instrument closure according to claim 1 , wherein the sensor retainer is at least partially retained within the instrument closure retainer.

11. The instrument closure according to claim 1 , wherein at least one aperture of the plurality of apertures is fluidically connected to a passage in the sensor retainer, and wherein the passage is transverse to the central longitudinal axis of the instrument closure.

12. The instrument closure according to claim 1 , wherein the sensor mount is formed integrally with the sensor retainer.

13. The instrument closure according to claim 1 , wherein the sensor mount is formed separately from the sensor retainer.

14. An instrument closure comprising:
an instrument closure retainer to retain the instrument closure onto a container;
a sensor retainer including a face that is positioned away from the container when the instrument closure is retained onto the container; and
a sensor mount to retain a sensor,
wherein the sensor mount is positioned on the face,
wherein the sensor mount includes a cylindrical cross-section including a central longitudinal axis to retain the sensor including a complementary shape substantially within the sensor mount, and
wherein the central longitudinal axis of the sensor mount is coaxial with a central longitudinal axis of the sensor retainer.

15. The instrument closure according to claim 14 , wherein the sensor mount is dimensioned to maintain the sensor at a predetermined distance from the container.

16. The instrument closure according to claim 14 , wherein the sensor retainer is at least partially retained within the instrument closure retainer.

17. An instrument closure comprising:
an instrument closure retainer to retain the instrument closure onto a container; and
a sensor retainer that is at least partially retained within the instrument closure retainer,
wherein the sensor retainer retains a sensor at a predetermined distance from the container when the instrument closure is retained onto the container,
wherein the sensor retainer further includes a sensor mount that is attached to or formed with the sensor retainer and configured to protrude from the sensor retainer to retain the sensor, and
wherein the sensor mount includes at least two semi-circular sensor mount structures that are oppositely disposed, include a gap therebetween along a central longitudinal axis of the sensor retainer, and form a partial cylindrical cross-section to retain the sensor that includes a cylindrical configuration substantially within the sensor mount.

18. The instrument closure according to claim 17 ,
wherein the sensor retainer includes a first face that is positioned towards the container and a second opposite face that is positioned away from the container when the instrument closure is retained onto the container, and
wherein the sensor mount is positioned on the second face.

19. The instrument closure according to claim 17 , further comprising:
a tapered passage formed within the sensor retainer to transmit signals emitted from the sensor towards fluid in the container and receive the signals reflected by a fluid surface of the fluid in the container,
wherein the tapered passage includes a substantially constant taper from the sensor towards the fluid in the container.

20. The instrument closure according to claim 17 , wherein the sensor includes an ultrasonic sensor.
