  • Patent number: 3993274
    Abstract: A bottle holding frame for infants includes a pair of spaced apart support frames of generally inverted U-shape, and a rotatable bridge member extending transversely between the tops of the support frames. A bottle holder carried on the bridge member clamps around a bottle to hold it in a downwardly tilted position for a baby placed under the bottle holding frame. A stop arm at one end of the bridge member rotates with the bridge member and can be positioned so it either holds the bottle in a fixed tilted position, or it allows the bottle to rotate freely, so that when the baby releases the bottle, it rotates to a position which prevents the bottle contents from dripping on the baby.
