Abstract

Cradles for draining liquid from containers are described herein. An example apparatus includes a housing having a bottom wall, a side wall and an open top. The housing is to receive a container having liquid. The example apparatus includes a probe extending upward from the bottom wall toward the open top and is to drain the liquid from the container when the probe is inserted into the container. The example apparatus also includes a sliding lock slidably disposed within the housing that receives a cap or top of the container when the container is inserted into the housing. The sliding lock includes a key slot. The sliding lock is movable when a cap or top of the container has a matching key that engages the key slot, which enables the sliding lock to move downward to expose the probe and drain the liquid from the container.

Claims

1. An apparatus comprising:

a housing having a bottom and an open top, the housing to receive a container having liquid;

a probe extending upward from the bottom toward the open top, the probe to drain the liquid from the container when the probe is inserted into the container;

a sliding lock slidably disposed within the housing, the sliding lock including;

an engagement surface;

an opening in the engagement surface to receive the probe therethrough when the sliding lock is moved from a first position in which the engagement surface is above a tip of the probe to a second position in which the engagement surface is below the tip of the probe; and

a key slot in the engagement surface; and

means for preventing movement of the sliding lock in the housing until a container key is inserted into the key slot of the sliding lock.

2. The apparatus of claim 1, wherein the means for preventing movement is disposed between the engagement surface and the bottom of the housing.

3. The apparatus of claim 1, further including means for releasably securing the container to the housing once the container is inserted into the housing.

4. The apparatus of claim 3, further including means for biasing the container upward to eject the container from the housing after the means for releasably securing is released.

5. The apparatus of claim 1, further including means for indicating when the container is fully inserted into the housing.

6. The apparatus of claim 1, further including means for determining a level of the liquid within the container.

7. The apparatus of claim 6, further including means for indicating when the level of the liquid is low or the container is empty.

8. An apparatus comprising:

a housing having a bottom wall, a side wall and an open top, the housing to receive a container having liquid;

a probe extending from the bottom wall toward the open top; and

a sliding lock slidably disposed within the housing, the sliding lock operable between a locked state in which movement of the sliding lock is prevented and an unlocked state in which the sliding lock is movable toward the bottom wall of the housing to enable the probe to be inserted into a cap of the container, the sliding lock further including a key slot, the sliding lock operable in the unlocked state when a key on the cap having a shape that corresponds to the key slot is inserted into the key slot.

9. The apparatus of claim 8, wherein the sliding lock includes an opening to receive the probe therethrough when the sliding lock is moved toward the bottom wall of the housing.

10. The apparatus of claim 8, further including a lockout that is movable between a locked position in which the lockout prevents the sliding lock from moving in the locked state and an unlocked position in which the sliding lock enables the sliding lock to move in the unlocked state.

11. The apparatus of claim 10, wherein the lockout is disposed between an engagement surface of the sliding lock and the bottom wall of the housing.

12. The apparatus of claim 10, further including a trigger disposed in the housing below the sliding lock, the trigger engageable with the key to move the trigger toward the bottom wall of the housing to move the lockout to the unlocked position.

13. The apparatus of claim 10, wherein the lockout is moveable in an opening formed in the side wall of the housing.

14. The apparatus of claim 13, wherein the lockout is a first lockout, further including a second lockout coupled to the side wall of the housing opposite the first lockout.

15. The apparatus of claim 8, further including a latch to engage a rim on the container or the cap of the container to releasably secure the container in the housing when the container is inserted into the housing.

16. The apparatus of claim 15, further including a release button to release the latch from the container or the cap of the container when the release button is activated.

17. The apparatus of claim 16, further including a light disposed in the release button, the light to illuminate the release button when the container is fully inserted into the housing and the latch is in a locked position.

18. The apparatus of claim 16, wherein the sliding lock is movable along a first axis and the release button is movable along a second axis parallel to the first axis.

19. The apparatus of claim 18, wherein the housing is a first housing, and wherein the release button is disposed within a second housing along a side of the first housing.

20. The apparatus of claim 8, wherein the key slot is a ring-shaped slot.
