Abstract
A device for use in increasing milk flow from a feeder bottle. The device includes a shaft adapted for entry into a correspondingly shaped hole in the feeder bottle. The device further includes a retention element for retaining the device in the hole and a channel, formed in a wall of the shaft. The shaft is movable such that it can, in a first position, seal the hole closed and, in another position (illustrated), permit airflow into the feeder bottle via the channel.
Claims13
A lid for a feeding bottle adapted for use with an animal feeding teat, said lid including a breather hole and a thin membrane releasably covering said breather hole,
- wherein the lid has a disk shaped wall with a skirt depending from a peripheral edge thereof, an aperture formed centrally in the wall and through which a feeding teat can be engaged, the thin membrane being of annular form with the opening therein being aligned with said aperture,
- wherein the breather hole is located in the disk shaped wall and the thin membrane is held against an inside surface of the disk shaped-wall whereby a part of the membrane covers the breather hole, and
- wherein a peripheral part of the membrane is free to flex away from the breather hole.
A feeding bottle having a venting hole, said bottle comprising:
- a mouth;
- a lid removably mounted with the mouth;
- a breather hole in the lid;
- a thin membrane releasably covering the breather hole;
- a feeding teat mounting aperture in the lid;
- a venting device for insertion into said venting hole, said venting device comprising:
- an elongate shaft having first and second ends;
- a head, said first end terminating at said head;
- an elongate channel in an outer wall of said elongate shaft terminating at said head;
- and
- a sealing portion at the second end for sealing the bottle,
- wherein said elongate shaft is longitudinally moveable from a first position where said sealing portion contacts a perimeter of the venting hole, to a second position where the channel establishes a clearance between the venting hole and the shaft so that air is moveable both into and out of the bottle through the channel.
