Abstract

A portable vacuum unit for use with a resealable, evacuable container, comprising a vacuum pump housed within a body, an accumulator removably coupled to the body and in fluid communication with a vacuum port of the body, the accumulator comprising a receptacle, a tip, wherein a first end of the tip is coupled to a first end of the receptacle and in fluid communication therewith, the tip having a shape which facilitates interaction with a valve on the resealable, evacuable container, the tip comprising at least one support structure and a semi-rigid material coupled to a second end of the tip.

Claims (31)

1. A portable vacuum unit for use with a resealable, evacuable container, comprising:

a body, wherein a vacuum pump is housed within the body, the vacuum pump comprising an intake port and an exhaust port, wherein the body comprises a vacuum port in fluid communication with the intake port of the vacuum pump, and wherein the body further comprises an exhaust port in fluid communication with the exhaust port of the vacuum pump;

an accumulator, wherein the accumulator is removably coupled to the body and in fluid communication with the vacuum port of the body, the accumulator comprising:

i) a receptacle comprising a first end and a second end; and,

ii) a tip comprising a first end and a second end, wherein the first end of the tip is coupled to the first end of the receptacle and in fluid communication therewith, the tip having a shape which facilitates interaction with a valve on the resealable, evacuable container, the tip comprising:

(1) at least one support structure proximate to a second end of the tip; and,

(2) a semi-rigid material coupled to the a second end of the tip wherein the receptacle and the tip are both rigid, and the first end of the tip is spatially coupled to the first end of the receptacle by way of a conduit.

2. The portable vacuum unit of claim 1 , wherein an adhesive couples the semi-rigid material to the second end of the tip.

3. The portable vacuum unit of claim 1 , wherein the semi-rigid material is nitrile.

4. The portable vacuum unit of claim 3 , wherein the semi-rigid material is formed as an O-ring.

5. The portable vacuum unit of claim 4 , wherein tip further comprises a channel in the second end thereof, wherein the channel is sized to receive and retain the O-ring.

6. The portable vacuum unit of claim 1 , wherein the tip comprises a plurality of support structures.

7. The portable vacuum unit of claim 6 , wherein the plurality of support structures comprises a plurality of ribs.

8. The portable vacuum unit of claim 1 , wherein the accumulator further comprises a liquid separator, wherein the liquid separator is in fluid communication with the tip and the vacuum port of the pump body.

9. The portable vacuum unit of claim 1 , wherein the conduit is flexible.

10. The portable vacuum unit of claim 1 , wherein the vacuum pump is battery powered, and wherein the body further comprises a battery compartment.

11. The portable vacuum unit of claim 10 , wherein the battery compartment houses at least one battery, and wherein the at least one battery is disposable.

12. A portable vacuum unit for use with a resealable, evacuable container, comprising:

a body, wherein a vacuum pump is housed within the body, the vacuum pump comprising an intake port and an exhaust port wherein the body comprises a vacuum port in fluid communication with the intake port of the vacuum pump, and wherein the body further comprises an exhaust port in fluid communication with the exhaust port of the vacuum pump;

an accumulator, wherein the accumulator is removably coupled to the body and in fluid communication with the vacuum port of the body, the accumulator comprising:

i) a receptacle comprising a first end and a second end;

ii) a tip, wherein a first end of the tip is coupled to a first end of the receptacle and in fluid communication therewith, the tip having a shape which facilitates interaction with a valve on the resealable, evacuable container, the tip comprising:

(1) at least one support structure proximate to a second end of the tip; and,

(2) a semi-rigid material coupled to the a second end of the tip; and,

iii) a liquid separator, wherein the liquid separator is in fluid communication with the tip and in fluid communication with the vacuum port of the pump body wherein the receptacle and the tip are both rigid, and the first end of the tip is spatially coupled to the first end of the receptacle by way of a conduit.

13. The portable vacuum unit of claim 12 , wherein an adhesive couples the semi-rigid material to the second end of the tip.

14. The portable vacuum unit of claim 12 , wherein the semi-rigid material is nitrile.

15. The portable vacuum unit of claim 14 , wherein the nitrile is formed as an O-ring.

16. The portable vacuum unit of claim 15 , wherein tip further comprises a channel in the second end thereof, wherein the channel is sized to receive and retain the O-ring.

17. The portable vacuum unit of claim 12 , wherein the tip comprises a plurality of support structures.

18. The portable vacuum unit of claim 17 , wherein the plurality of support structures comprises a plurality of ribs.
