Liquid dispensing device
A liquid dispensing device includes a needle. The needle is adapted to penetrate a container without tearing out a portion of the container. The portion of the container is near a point of penetration on the container. The liquid dispensing device includes a motion control system. The motion control system is configured to rotate the needle while the needle penetrates the container.
1. A liquid dispensing device, comprising:
a needle adapted to penetrate a container without tearing out a portion of the container near a point of penetration on the container, wherein the needle comprises:
a smooth cylindrical body;
a plurality of extraction ports for extracting a liquid from the container, wherein each extraction port of the plurality of extraction ports comprises:
an extraction recessed portion; and
an extraction opening disposed in the extraction recessed portion; and
an injection port for injecting a gas into the container; and
a motion control system configured to rotate the needle while the needle penetrates the container.
2. The device of claim 1 , wherein the injection port and the plurality of extraction ports are hydraulically separated from each other within the needle.
3. The device of claim 2 , wherein the needle further comprises:
a point;
a tapered portion; and
a length.
4. The device of claim 3 , wherein the injection port is disposed between the point and the plurality of extraction ports.
5. The device of claim 3 , wherein the injection port is disposed between the tapered portion and the plurality of extraction ports.
6. The device of claim 3 , wherein the tapered portion tapers from the point to a first diameter, wherein the length has a second diameter, wherein the first diameter is smaller than the second diameter.
7. The device of claim 3 , wherein the needle further comprises:
a recessed portion having a first diameter,
wherein the length has a second diameter,
wherein the first diameter is smaller than the second diameter.
8. The device of claim 7 , wherein the recessed portion is disposed between the point and the plurality of extraction ports.
9. The device of claim 7 , wherein the recessed portion is disposed between the tapered portion and the plurality of extraction ports.
10. The device of claim 7 , wherein the recessed portion is disposed along the length of the needle.
11. The device of claim 7 , wherein the injection port is disposed in the recessed portion.
12. The device of claim 7 , wherein the recessed portion is not symmetric along the length of the needle.
13. The device of claim 7 , wherein the injection port is offset along the length of the needle from a most recessed point of the recessed portion.
14. The device of claim 1 , wherein the needle further comprises:
an injection opening of the injection port disposed at a first distance from a longitudinal axis of the smooth cylindrical body; and
wherein the extraction opening is at a second distance from a longitudinal axis of the smooth cylindrical body, wherein the first distance is less than the second distance.
15. The device of claim 14 , wherein the needle further comprises:
a point disposed along the longitudinal axis of the smooth cylindrical body; and
a tapered portion disposed between the point and the smooth cylindrical body.
16. The device of claim 14 , wherein a longitudinal axis of the injection port is oblique to the longitudinal axis of the smooth cylindrical body.
17. The device of claim 14 , wherein the needle further comprises:
a recessed portion,
wherein the opening of the injection port is disposed in the recessed portion.
18. The device of claim 17 , wherein the recessed portion is asymmetrical about the opening of the injection port.
19. The device of claim 17 , wherein the opening of the injection port is not disposed at a most recessed point of the recessed portion.
20. The device of claim 17 , wherein the recessed portion is asymmetrical about a most recessed point of the recessed portion.
