Baby feeding bottle
A baby bottle device ( 100 ) is provided which comprises a teat ( 110 ) having a teat volume ( 115 ), a container ( 120 ) having a container volume ( 125 ) and a partitioning element ( 300 ) between the teat volume ( 110 ) and the container volume ( 125 ). The partitioning element ( 300 ) comprises a plurality of openings ( 310 ) for letting fluid in the container volume ( 125 ) flow into the teat volume ( 115 ). The baby bottle device comprises a floater ( 400 ) having a buoyancy, being coupled to the partitioning element ( 300 ) and being adapted to close at least one of the plurality of openings ( 310 ) in the partitioning element ( 300 ).
1. A baby bottle device, comprising
a teat having a teat volume,
a container having a container volume,
a partitioning element at an open end of the container between the teat volume and the container volume, having a plurality of openings for letting fluid in the container volume flow into the teat volume, and
a floater having a buoyancy, and being coupled to the partitioning element, wherein the floater is adapted to float in a liquid in the container volume when liquid is present at the open end of the container,
wherein, when floating, the floater is adapted to: close at least one opening of the partitioning element, which is located at a vertically upper region of the partitioning element, due to the buoyancy of the floater causing the floater to float to said vertically upper region of the partitioning element; and, at the same time, open at least one opening of the partitioning element which is located at a vertically lower region of the partitioning element.
2. The baby bottle device according to claim 1 , further comprising an adapter for coupling the teat to the container.
3. The baby bottle device according to claim 1 , wherein the floater comprises a hollow chamber filled with air in order to provide a required buoyancy or is made of a material which has a lower density than milk to enable it to float on milk.
4. The baby bottle device according to claim 1 , further comprising at least one valve adapted to let out air from the teat volume to the container volume.
5. The baby bottle device according to claim 1 , further comprising a flexible element coupled to the partitioning element and/or the floater.
6. The baby bottle device according to claim 5 , wherein the flexible element serves to seal or cover at least part of the at least one opening in the partitioning element.
7. The baby bottle device according to claim 5 , wherein the flexible element acts as a valve to let out air from the teat volume.
8. The baby bottle device according to claim 1 , wherein a cross section of the floater is smaller than a cross section of the partitioning element.
9. A partitioning system for a baby bottle device, the baby bottle device comprising a container having a container volume, and a teat having a teat volume, wherein the partitioning system comprises:
a partitioning element for mounting at an open end of the container between the teat volume and the container volume, having a plurality of openings for letting fluid in the container volume flow into the teat volume; and
a floater having a buoyancy, and being coupled to the partitioning element, wherein the floater is adapted to float in a liquid in the container volume when liquid is present at the open end of the container,
wherein, when floating, the floater is adapted to: close at least one opening of the partitioning element, which is located at a vertically upper region of the partitioning element, due to the buoyancy of the floater causing the floater to float to said vertically upper region of the partitioning element; and, at the same time, open at least one opening of the partitioning element which is located at a vertically lower region of the partitioning element.
10. A teat assembly comprising:
the partitioning system of claim 9 ; and
the teat.
11. The partitioning system according to claim 9 , further comprising an adapter for coupling the teat to the container.
12. The partitioning system according to claim 9 , wherein the floater comprises a hollow chamber filled with air in order to provide a required buoyancy or is made of a material which has a lower density than milk to enable it to float on milk.
13. The partitioning system according to claim 9 , further comprising at least one valve adapted to let out air from the teat volume to the container volume.
14. The partitioning system according to claim 9 , further comprising a flexible element coupled to the partitioning element and/or the floater.
15. The partitioning system according to claim 14 , wherein the flexible element serves to seal or cover at least part of the at least one opening in the partitioning element.
16. The partitioning system according to claim 14 , wherein the flexible element acts as a valve to let out air from the teat volume.
17. The partitioning system according to claim 9 , wherein a cross section of the floater is smaller than a cross section of the partitioning element.
