An insert may be used with a container that includes a lid with a suction opening and a liquid storage portion where the lid threads onto the liquid storage portion to allow liquid from the liquid storage portion to be consumed through the suction opening by a user. The insert includes a barrier with an outer perimeter that is configured to be captured, and form a seal against liquid, between the lid and the liquid storage portion when the lid is threaded onto the liquid storage portion; a first one-way valve through the barrier and configured to allow the liquid to flow from the liquid storage portion to the suction opening during consumption of the liquid by the user; and a second one-way valve configured to allow air to flow into the liquid storage portion.

1. An insert for use with a container that includes a lid with a suction opening and a liquid storage portion where the lid threads onto the liquid storage portion to allow liquid from the liquid storage portion to be consumed through the suction opening by a user, the insert comprising: a barrier with an outer perimeter that is configured to be captured, and form a seal against liquid, between the lid and the liquid storage portion when the lid is threaded onto the liquid storage portion;a first one-way valve through the barrier and configured to allow the liquid to flow from the liquid storage portion to the suction opening during consumption of the liquid by the user; anda second one-way valve configured to allow air to flow into the liquid storage portion, the second one-way valve being configured to provide fluid communication from the threads to the storage portion; whereinthe insert is configured so that external fluid can flow from the threads, to the second one-way valve and into the storage portion when the barrier is between the lid and the liquid storage portion but fluid cannot flow from the threads to the suction opening when the barrier is between the lid and the liquid storage portion without first flowing into the liquid storage portion, andthe insert is configured to be removably and repeatably inserted to be retained between the lid and the liquid storage portion at a location that the lid is able to seal against the liquid storage portion without the insert. 2. The insert according to claim 1, wherein the barrier is configured to form a chamber with the lid such that the chamber is in fluid communication with the first one-way valve and the suction opening, and the chamber is not in fluid communication with the second one-way valve. 3. The insert according to claim 1, wherein the first one-way valve is a duck bill check valve. 4. The insert according to claim 3, wherein the second one-way valve is not a duck bill check valve. 5. The insert according to claim 3, wherein the second one-way valve is a reed valve. 6. The insert according to claim 1, wherein the barrier, the first one-way valve and the second one-way valve are parts of a unitary molded body. 7. The insert according to claim 1, wherein the first one-way valve is configured to open with a differential pressure between 0 and 0.14 psi. 8. The insert according to claim 1, wherein the second one-way valve is configured to allow external air to flow into the liquid storage portion during consumption of the fluid by the user. 9. The insert according to claim 1, wherein the second one-way valve is configured so that when the container is inverted and the liquid contacts the second one-way valve, sealing force of the second one-way valve is increased due to the weight of the fluid. 10. The insert according to claim 1, wherein the first one-way valve is configured to open due to the weight of the liquid on the first one-way valve when the container is inverted, there is no liquid below the insert and the user does not provide suction. 11. A bottle for nursing by an infant comprising a threaded lid with a nipple for nursing;a threaded body configured to store fluid; andthe insert according to claim 1 compressed by and between the threaded lid and the threaded body. 12. A beverage container comprising a threaded lid with an opening configured for removal of liquid by suction;a threaded body configured to store the liquid; andthe insert according to claim 1 compressed by and between the threaded lid and the threaded body. 13. The insert according to claim 1, wherein the insert is a substantially flat disc except at the first one-way valve. 14. An insert for use with a container that includes a lid with a suction opening and a liquid storage portion where the lid threads onto the liquid storage portion to allow liquid from the liquid storage portion to be consumed through the suction opening by a user, the insert comprising: a barrier with an outer perimeter that is configured to be captured, and form a seal against liquid, between the lid and the liquid storage portion when the lid is threaded onto the liquid storage portion;a first one-way valve through the barrier and configured to allow the liquid to flow from the liquid storage portion to the suction opening during consumption of the liquid by the user, the first one-way valve being a duck bill check valve; anda second one-way valve configured to allow air to flow into the liquid storage portion, the second one-way valve being configured to provide fluid communication from the threads to the storage portion, the second one-way valve being a reed valve; whereinthe barrier, the first one-way valve and the second one-way valve are parts of a unitary body;the barrier is configured to form a chamber with the lid such that the chamber is in fluid communication with the first one-way valve and the suction opening, and the chamber is not in fluid communication with the second one-way valve;the second one-way valve is configured to protrude into the chamber and thus reduce a volume of the chamber; andthe insert is configured so that external fluid can flow from the threads, to the second one-way valve and into the storage portion when the barrier is between the lid and the liquid storage portion but fluid cannot flow from the threads to the suction opening when the barrier is between the lid and the liquid storage portion without first flowing into the liquid storage portion. 15. The insert according to claim 14, wherein the first one-way valve is configured to open with a differential pressure between 0 and 0.14 psi. 16. The insert according to claim 14, wherein the second one-way valve is configured to allow external air to flow into the liquid storage portion during consumption of the fluid by the user. 17. The insert according to claim 14, wherein the second one-way valve is configured so that when the container is inverted and the liquid contacts the second one-way valve, sealing force of the second one-way valve is increased due to the weight of the fluid. 18. The insert according to claim 14, wherein the first one-way valve is configured to open due to the weight of the liquid on the first one-way valve when the container is inverted, there is no liquid below the insert and the user does not provide suction. 19. A bottle for nursing by an infant comprising a threaded lid with a nipple for nursing;a threaded body configured to store fluid; andthe insert according to claim 14 compressed by and between the threaded lid and the threaded body. 20.
