The invention relates to a baby feeding bottle.
During the baby feeding with a bottle, the baby may swallow air together with the milk from the bottle. This can result in colic. A colic is a condition some infants suffer from during early months and is caused by air in the digestive system. Air ingestion is unavoidable both in breast feeding and bottle feeding due to the presence of vacuum in the infant's mouth during feeding. It is, however, desired to reduce the amount of air ingestion by the infant to reduce the risk of a colic.
WO 2018/162366 discloses a baby feeding bottle with a container, an adapter and a teat. Furthermore, a partitioning is provided between the teat volume and the volume of the container. The partition allows fluid to flow from the container into the teat and that air inside the teat volume can escape into the container volume in order to reduce the amount of air in the teat volume.
U.S. Pat. No. 2,764,155 discloses a baby bottle having a floating ball in a cage between the bottle and the teat. When the bottle is nearly empty (i.e. there is less milk than fills the teat) the ball sinks to prevent air entering the teat.
US 2007/0163983 discloses a baby bottle having a seal disc in the bottle which closes openings between bottle volume and the teat when the bottle is nearly empty. This again prevents air entering the teat.
There remains a problem that air can enter the teat even when the bottle is not nearly empty. For example, if the bottle is not vertically inverted during use there may be an air volume at an upper side and a milk volume at a lower side, and the air volume may couple to the teat, still allowing air to enter the teat.
It is an object of the invention to provide a baby feeding bottle with an improved colic prevention capability. It is in particular an object of the invention to provide a baby feeding bottle which can efficiently prevent air flowing into a teat volume.
The invention is defined by the claims.
According to an aspect of the invention, a baby bottle device is provided which comprises a teat having a teat volume, a container having a container volume and a partitioning element between the teat volume and the container volume. The partitioning element comprises a plurality of openings for letting fluid in the container volume flow into the teat volume. The baby bottle device comprises a floater having a buoyancy, being coupled to the partitioning element and being adapted to close at least one of the plurality of openings in the partitioning element. Hence, a baby feeding bottle can be provided which is rotation independent. The baby bottle can used in any rotational orientation.
According to an embodiment, an adapter is provided for coupling the teat and the container.
According to a further embodiment, the floater comprises a hollow chamber filled with air in order to provide the required buoyancy.
According to an embodiment, the floater is adapted to float if liquid is present in an open end of the container such that the floater closes those openings in the partitioning element which are arranged at a top side.
According to a further embodiment, the baby bottle device furthermore comprises a flexible element coupled to the partitioning element and the floater. The flexible element is coupled to the floater and is in loose contact with the partitioning element. Thus, with the flexible element, an improved sealing of the openings can be provided preventing air entering the teat volume. The flexible sheet allows a sealing between the floater and the openings.
According to an embodiment, a valve can be provided to let out air from the teat volume into the container volume. The flexible element can function as a valve. Alternatively, the valve can be a duck-bill valve.
The invention also provides a partitioning system for a baby bottle device comprising the partitioning element and floater of the baby bottle defined above.
It shall be understood that a preferred embodiment of the present invention can also be any combination of the dependent claims or above embodiments with the respective independent claim.
These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
In the following drawings:
Optionally, a valve may be present to let in air into the container volume.
A partitioning element 300 is provided between the teat 110 and the container 120. The partitioning element 300 can have several holes 310 (sometimes referred to herein as openings 310) arranged, for example in a circle to allow liquid to flow from the container into the teat. The partitioning element 300 can have a valve 320 for letting out air from the container volume 125 into the teat volume 115. The valve can be e.g. duck-bill valve.
As soon as the bottle is not perfectly vertically inverted, there will be one or more vertically upper openings and one or more vertically lower openings. Thus, vertically upper and vertically lower should be understood to be relative terms. The partitioning element does not need to be vertically positioned in order for vertically upper and vertically lower holes to be present. Any non-horizontal orientation will result in relatively upper and relatively lower regions.
Optionally, a flexible sheet 500 can be provided between the floater 400 and the partitioning element 300. The flexible sheet 500 serves to seal the floater 400 and the partitioning element.
The end of the flexible sheet 500 (sometimes referred to herein as flexible element 500) covering the holes 310 can function as the valve 320 letting out air from the teat volume 115 into the container volume 125. The flexible sheet 500 can be pushed away from the opening 310 such that air can flow from the teat volume to the container volume.
The flexible sheet or flexible element 500 can be attached or coupled to either to the floater 400 or the partitioning element 300. If the flexible element 500 is attached to the partitioning element 300, the flexible sheet may also comprise holes or openings corresponding to the holes and openings of the partitioning element.
The flexible sheet or flexible element 500 may also be connected to the floater 400. In this case, the flexible sheet 500 or the ends of the flexible sheet 500 may act as a valve for letting out air from the teat volume into the container volume.
According to an embodiment, the flexible sheet 500 is optional. This can in particular work if the surfaces of the floater and the partitioning element are sufficiently smooth to enable a closing of holes by the floater.
According to a further embodiment, the flexible sheet may be connected to the floater for example in form of a flexible lip around the circumference of the floater. Accordingly, the flexible sheet may be stationary or can be moved relative to the partitioning element or the floater.
Due to the buoyancy of the floater 400, the flexible sheet 500 can be moved into a position in order to close off and open holes in the partitioning element which can be implemented as a separation wall.
According to an embodiment, the floater 400 and the flexible sheet 500 are able to move with respect to the partitioning element 300 and are adapted to stay in close distance to the partitioning element 300 in order to be able to close off the holes 310 in the partitioning element 340. This is advantageous as the floater 400 and the flexible sheet 500 can block those openings through which air can leak into the teat volume. The flexible sheet 500 can be of e.g. oval or circular shape. The floater 400 is adapted to rotate depending on the orientation of the baby bottle 100 when the teat 110 is filled. The oval shaped flexible sheet 500 can be aligned with the liquid interface to close the holes 310 which are exposed to air inside the container. As the floater 400 closes off those openings 310 through which milk can enter into the teat volume 115, the floater 400 will open other openings through which air can flow into the teat volume 115. Accordingly, the cross section of the floater is smaller than the cross section of the partitioning element. Furthermore, the cross section of the floater is smaller than a circle along which the openings 310 are arranged.
According to an embodiment, the floater 400 is at least partly hollow to create the required buoyancy. Alternatively, the floater can be made from a material which has a lower density than milk to enable it to float on milk. As shown in
Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims.
The partitioning element and floater of the baby bottle device described above may be considered to be a partitioning system, and may be provided as a separate replaceable unit.
In the claims, the word “comprising” does not exclude other elements or steps, and the indefinite article “a” or “an” does not exclude a plurality.
A single unit or device may fulfill the functions of several items recited in the claims. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
A computer program may be stored/distributed on a suitable medium, such as an optical storage medium or a solid-state medium, supplied together with or as part of other hardware, but may also be distributed in other forms, such as via the Internet or other wired or wireless telecommunication systems.
Any reference signs in the claims should not be construed as limiting the scope.
