Abstract
A device (10) for use in increasing milk flow from a feeder bottle (B). The device (10) includes a shaft (11) adapted for entry into a correspondingly shaped hole (H) in the feeder bottle (B). The device further includes a retention element for retaining the device in the hole (H) and a channel element (13), formed in a wall of the shaft (11). The shaft element (11) is movable such that it can, in a first position, seal the hole (H) closed and, in another position (illustrated), permit airflow into the feeder bottle (B) via the channel element (13).
Claims19
A feeding bottle including a hole formed in said bottle and a venting device, said venting device including an elongate shaft longitudinally inserted in the hole, the elongate shaft having a distal end which in use is located within the feeding bottle, a retention part associated with the distal end to retain the distal end within the bottle, and a channel, the shaft further including a sealing portion and a finger grippable portion, said shaft being moveable longitudinally from a sealing position, where the sealing portion sealingly contacts a perimeter of the hole, to a venting position where the channel establishes a clearance between the hole and the shaft for venting the bottle.
A feeding bottle having a venting hole, said bottle comprising:
- a venting device for insertion into said 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.
A feeding bottle having a venting hole, said bottle comprising:
- a venting device for insertion into said 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 said elongate shaft terminating at said head;
- a sealing portion at the second end for sealing the bottle;
- and
- a stop on said shaft nearer to said first end than said second end,
- wherein said elongate shaft is moveable from a first position where said sealing portion contacts a perimeter of the venting hole to a second position where the stop contacts a perimeter of the venting hole.
