Partitioning component for a feeding bottle device and feeding bottle device

A feeding bottle device comprising:

• a teat component defining a teat volume therein,
• a container component defining a container volume therein,
• a partitioning component comprising a first passage allowing a passage of fluid from the container volume to the teat volume and a second passage allowing a passage of fluid from the teat volume to the container volume, wherein the second passage is provided in the form of a one-way passage, wherein the first passage and the second passage are integrated within the partitioning component, wherein the partitioning component further comprises a guiding component for guiding the partitioning component into an opening of the container component, and wherein the second passage is located higher with respect to the first passage in an operating position of the bottle feeding device,
• an attachment component, the teat component the container component and the partitioning component being attachable to each other along a contact area by means of the attachment component, and
• at least one air vent valve located in the attachment area of the attachment component at an arbitrary rotational position about the circumference of the attachment area, configured to allow the passage of air from outside the feeding bottle device to within the teat volume or the container volume thereby reducing a vacuum in the teat volume whilst an infant is suckling from the teat component,
• a confined volume forming component provided adjacent a wall of the container component, arranged to define a confined volume within the container volume, wherein the confined volume provides a controlled opening for releasing air into the container volume, and
• a duct forming component for forming an annular guidance duct around a circumference of a contact area between the teat component and the container component, the duct extending from the at least one air vent valve to the confined volume, the duct configured for collecting air independent of the angular position of the air vent valve and guiding the air towards the confined volume to be released into the container volume via the controlled opening in a controlled manner.

A partitioning component for a feeding bottle device,

• the partitioning component being configured to separate a teat volume of a teat component of the feeding bottle from a container volume of a container component of the feeding bottle when the feeding bottle device is assembled,
• wherein the partitioning component comprises a first passage allowing a passage of fluid from the container volume to the teat volume and a second passage allowing a passage of fluid from the teat volume to the container volume, wherein the second passage is provided in the form of a one-way passage, wherein the first passage and the second passage are integrated within the partitioning component, and
• wherein the partitioning component further comprises a guiding component for guiding the partitioning component into an opening of the container component, and
• wherein the first passage and the second passage are formed as oppositely directed flap valves having respective hinge axes parallel to each other, and
• wherein the second passage is located higher with respect to the first passage in an operating position of the feeding bottle device.
