Baby bottle with milk pump
The present invention relates to an apparatus ( 2 ) comprising a connector ( 4 ), a baby bottle ( 6 ) which can be coupled thereto having a bottle body ( 8 ) and a bottle base ( 10 ), and a sensor unit ( 34 ) arranged in the bottle base ( 10 ) for determining the filling quantity of milk in the baby bottle ( 6 ). An object of the present invention is to improve handling and maintenance of the apparatus, as well as determining the content quantity. It is characterized in that the bottle base ( 10 ) is releasably attachable to the bottle body ( 8 ).
1. An apparatus comprising:
a connector;
a baby bottle coupled thereto having a bottle body, a bottle base releasably attached to said bottle body, and a sensor unit arranged in said bottle base for determining a filling quantity of milk in said baby bottle
and
a sensor unit arranged in said bottle base for determining a filling quantity of milk in said baby bottle, wherein said sensor unit comprises a coil arranged centrally in said bottle base and spaced from a membrane in said baby bottle and having one of a centrally arranged metallic insert or a metallic coating, the membrane being impermeable to milk, elastic, and movable in the direction of said sensor unit.
2. The apparatus according to claim 1 , wherein said membrane—when said baby bottle stands upright—moves toward said sensor unit when the filling quantity of milk increases and away from said sensor unit when the filling quantity of milk decreases.
3. The apparatus of claim 1 , wherein the axis of said metallic insert is at least approximately aligned with the axis of said coil.
4. The apparatus according to claim 1 , wherein electronic components are arranged between said coil and a bearing surface of said releasable bottle base formed by said bottle base.
5. The apparatus of claim 1 , wherein said bottle base is attachable by one of screwing, a bayonet lock, or a snap lock, to said bottle body of said baby bottle.
6. A baby bottle with a bottle body, a bottle base releasably attached to said bottle body, and a sensor unit arranged in said bottle base for determining the amount of content in said baby bottle, wherein said sensor unit comprises a coil arranged centrally in said bottle base and spaced from a membrane having a centrally arranged metallic insert or a metallic coating, the membrane being impermeable to milk, elastic and movable in the direction of said sensor unit.
7. The baby bottle according to claim 6 , wherein said membrane—when said baby bottle stands upright—moves toward said sensor unit when the filling quantity increases and away from said sensor unit when the filling quantity decreases.
8. The baby bottle according to claim 6 , wherein the axis of said metallic insert is at least approximately aligned with the axis of said coil.
9. The baby bottle according to claim 6 , wherein electronic components are arranged between said coil and a bearing surface of said releasable bottle base formed by said bottle base.
10. The baby bottle according to claim 6 , wherein said bottle base is attachable by screwing, a bayonet lock, or a snap lock to said bottle body of said baby bottle.
