Vessel for breast milk collection, preservation, transportation, and delivery
A vessel includes an inner container, an outer container, a connector, a cap, and a lid. The outer container includes a first coupler and an outer chamber. The inner container includes a second coupler and an inner chamber to hold a liquid. The inner container is receivable at least partially within the outer chamber. The connector includes a third coupler that is complementary to the first coupler, and a fourth coupler that is complementary to the second coupler. When both the first coupler is engaged with the third coupler and the second coupler is engaged with the fourth coupler, the outer chamber is entirely enclosed within a liquid-proof barrier.
1. A vessel for breast milk preservation, the vessel comprising:
an outer container having an outer container coupler, an insulating structure comprising a double walled body having a first wall spaced apart from a second wall by a vacuum-sealed gap, and an outer chamber with an inner surface, wherein the outer container coupler comprises outer container threads positioned on the inner surface of the outer container, the insulating structure extends at least partially along the outer container threads, and the insulating structure and the outer container threads are part of a unitary structure of the outer container;
an inner container receivable at least partially within the outer chamber, the inner container having an inner container coupler comprising inner container threads; and
a connector having first connector threads, second connector threads positioned radially inward of the first connector threads, and third connector threads, wherein
the first connector threads and the third connector threads are complementary to and configured to engage the outer container threads,
the third connector threads are reversed in orientation relative to the first connect threads, and
the second connector threads are complementary to and configured to engage the inner container threads,
wherein, when the outer container threads are engaged with the first connector threads and the inner container threads are engaged with the second connector threads, the outer chamber is entirely enclosed within a liquid-proof barrier.
2. The vessel of claim 1 wherein the outer chamber is configured to receive a liquid.
3. The vessel of claim 2 wherein the vessel is configured to maintain breast milk within the outer chamber at a chilled storage temperature for at least six hours.
4. The vessel of claim 1 wherein the inner container is receivable at least partially within the outer chamber such that a gap is formed between the inner container and the outer container.
5. The vessel of claim 1 wherein the outer container threads are internal threads having a first pitch, and the first connector threads are external threads having the first pitch.
6. The vessel of claim 1 wherein the inner container threads are external threads having a pitch and the second connector threads are internal threads having the pitch.
7. The vessel of claim 1 , further comprising a cap portion having a plurality of flats to facilitate application of torque to rotate the cap portion about a central axis.
8. The vessel of claim 1 wherein the outer container is configured to receive a cooling medium.
9. The vessel of claim 1 wherein the outer container is configured to retain a volume of liquid of at least 12 oz.
10. The vessel of claim 1 wherein the vessel is configured to maintain contents within the outer chamber at a chilled storage temperature for at least six hours.
11. The vessel of claim 1 , further comprising a sealer coupled to the inner container, wherein, when the inner container coupler engages with the connector, the sealer is positioned and captured between the inner container coupler and the connector to provide a liquid-proof barrier.
12. A vessel for liquid storage, the vessel comprising:
an outer container having outer container threads and an outer chamber, wherein the outer container comprises an insulating structure extending at least partially along the outer container threads, and wherein the outer container threads and the insulating structure are part of a unitary structure of the outer container;
an inner container receivable at least partially within the outer chamber, the inner container having an inner container coupler; and
a connector having a first connector coupler, a second connector coupler, and a third connector coupler, wherein
the first connector coupler and the third connector coupler are configured to engage with the outer container threads,
the third connector coupler is discontinuous with the first connector coupler such that the outer container threads cannot transition from engagement with the first connector coupler to engagement with the third connector coupler without first disengaging from the first connector coupler, and
the second connector coupler configured to engage with the inner container coupler,
wherein, when the outer container threads are engaged with the first connector coupler and the inner container coupler is engaged with the second connector coupler:
the first connector coupler is positioned within the outer chamber, and the outer chamber is entirely enclosed within a liquid-proof barrier.
13. The vessel of claim 12 wherein the first connector coupler is positioned radially outward of the second connector coupler.
14. The vessel of claim 12 wherein the outer chamber is configured to receive a liquid.
15. The vessel of claim 12 wherein the inner container is receivable at least partially within the outer chamber.
16. The vessel of claim 12 wherein the first connector coupler and the outer container threads include opposite threads with a first thread pitch and the second connector coupler and the inner container coupler include opposite threads with a second pitch.
17. A method for storing and cooling liquid, the method comprising:
transferring liquid to an outer chamber of an outer container of a vessel, wherein the outer container comprises an insulating structure defined by a double walled body having a first wall spaced apart from a second wall by a vacuum-sealed gap; engaging an inner container coupler of an inner container to first connector threads of a connector, wherein the inner container coupler comprises inner container threads;
inserting the inner container into the outer chamber; and
engaging an outer container coupler of the outer container to second connector threads of the connector, the outer container coupler comprising outer container threads disposed on an inner surface of the second wall defining the double walled body, wherein:
the insulating structure extends at least partially along the outer container threads, and
the connector further comprises third connector threads configured to engage with outer container coupler of the outer container, the third connector threads being discontinuous with the second connector threads such that the outer container coupler of the outer container cannot transition from engagement with the second connector threads to engagement with the third connector threads without first disengaging from the second connect threads;
wherein, when the outer container threads are engaged with the second connector threads and the inner container threads are engaged with the first connector threads, the outer chamber is entirely enclosed within a liquid-proof barrier.
18. The method of claim 17 , further comprising:
maintaining the liquid within the vessel at a temperature for at least six hours.
19. The method of claim 17 , further comprising forming a gap between the inner container and the inner surface of the outer container when the outer container threads are engaged with the second connector threads and the inner container threads are engaged with the first connector threads.
