## Abstract

A bottle feeding device, including a bottom piece of a bottle body having a first perimeter wall and a top piece of a bottle body having a second perimeter wall. The top piece is pivotally affixed to the bottom piece and is rotatable with respect to the bottom piece about an axis extending generally orthogonally through the first perimeter wall and the second perimeter wall. A pair of detent features is provided to restrain the bottom piece and the top piece into either a first relative rotational position or a second relative rotational position. A nipple is operatively affixed to the top piece of the bottle by a nipple ring threaded onto the top piece of the bottle. A method of feeding an infant and of manufacturing the bottle are also provided.

## Claims

### Claim 1

A bottle feeding device, comprising:
a bottom piece of a bottle body having a first perimeter wall;
a top piece of the bottle body having a second perimeter wall, wherein the top piece is pivotally affixed to the bottom piece and is rotatable with respect to the bottom piece about an axis extending generally orthogonally through the first perimeter wall and the second perimeter wall.

### Claim 2 (depends on 1)

The bottle feeding device of claim 1, further comprising:
a pair of detent features to restrain the bottom piece and the top piece into either a first relative rotational position or a second relative rotational position.

### Claim 3 (depends on 2)

The bottle feeding device of claim 2, wherein each detent feature includes a first protrusion from the first perimeter wall, and a corresponding second protrusion from the second perimeter wall which interacts with the first protrusion to resist rotational motion.

### Claim 4 (depends on 2)

The bottle feeding device of claim 2, wherein each detent feature includes a protrusion from the first perimeter wall and a corresponding indent in the second perimeter wall which interacts with the protrusion to resist rotational motion.

### Claim 5 (depends on 2)

The bottle feeding device of claim 2, wherein an angle between a central axis of the bottom piece and a central axis of the top piece is about 0° in the first relative rotational position and the angle between the central axis of the bottom piece and the central axis of the top piece is about 25° in the second relative rotational position.

### Claim 6 (depends on 2)

The bottle feeding device of claim 2, wherein the first relative rotational position is adapted for storage and filling of the bottle feeding device and the second relative rotational position is adapted for feeding an infant using the bottle feeding device.

### Claim 7 (depends on 1)

The bottle feeding device of claim 1, further comprising a rib extending around the first perimeter wall, wherein at least a portion of the rib extends around the first perimeter wall at an angle, and wherein the rib interacts with the second piece to limit rotation of the second piece with respect to the bottom piece.

### Claim 8 (depends on 7)

The bottle feeding device of claim 7, wherein at least one of the bottom piece and top piece of the bottle body has a rounded ball shape to facilitate rotation from the first relative rotational position to the second relative rotational position.

### Claim 9 (depends on 1)

The bottle feeding device of claim 1, further comprising:
a flexible overmolding extending from at least one of the bottom piece of the bottle body and the top piece of the bottle body, toward the other of the bottom piece and the top piece of the bottle body to prevent pinch points between the bottom piece and top piece as the top piece is rotated with respect to the bottom piece.

### Claim 10 (depends on 1)

The bottle feeding device of claim 1, wherein a top end of the top piece of the bottle body has a threaded portion which receives complementary threads of a nipple ring, and wherein the threaded portion and complementary threads include visual, audible and tactile indicators to alert the user that the nipple ring is securely fastened to the top piece of the bottle body.

### Claim 11 (depends on 1)

The bottle feeding device of claim 1, wherein a bottom end of the bottom piece of the bottle body has a circumferential groove to receive a hood to secure the hood to the bottom end.

### Claim 12 (depends on 1)

The bottle feeding device of claim 1, further comprising vent holes through the first perimeter wall to permit circulation of water about the bottle and to allow the bottle to sink within water during warming and sterilization.

### Claim 13 (depends on 1)

The bottle feeding device of claim 1, further comprising:
a nipple, operatively affixed to the top piece of the bottle by a nipple ring coupled onto the top piece of the bottle.

### Claim 14 (depends on 13)

The bottle feeding device of claim 13, further comprising:
a flexible drop-in liner to hold the liquid to be dispensed from the bottle which has a top opening, wherein the top opening of the liner is secured to the top piece of the bottle by the nipple ring and wherein the liner is in fluid communication with the nipple.

### Claim 15

A method of feeding an infant, comprising the steps of:
positioning a liner in a top opening of a bottle having a bottom piece with a first perimeter wall and a top piece having a second perimeter wall, with the top piece pivotally affixed to the bottom piece and rotatable with respect to the bottom piece about an axis extending generally orthogonally through the first perimeter wall and the second perimeter wall, with the top piece in a first relative rotational position with respect to the bottom piece;
filling the liner with a fluid;
rotating the top piece about the orthogonal axis to a second relative rotational position with respect to the bottom piece; and
positioning the bottle into an infant's mouth.

### Claim 16 (depends on 15)

The method of feeding an infant of claim 15, further comprising the steps of:
installing a nipple through a central hole of a nipple ring; and
affixing the nipple ring to the top opening of the bottle to secure the nipple and the liner to the bottle.

### Claim 17 (depends on 16)

The method of feeding an infant of claim 16, wherein the step of feeding the infant includes positioning the infant in a semi-upright position.

### Claim 18

A method of manufacturing a bottle, comprising the steps of:
forming a bottom piece of a bottle having a first perimeter wall and at least one detent feature;
forming a top piece of the bottle having a second perimeter wall and at least one corresponding detent feature which interacts with the detent feature in the bottom piece;
pivotally affixing the top piece of the bottle to the bottom piece of the bottle with a pivotal axis extending generally orthogonally through the first perimeter wall and the second perimeter wall, wherein the detent features and corresponding detent features restrain the top piece into a first relative rotational position or a second relative rotational position with respect to the bottom piece.

### Claim 19 (depends on 18)

The method of manufacturing the bottle of claim 18, wherein at least one of the top piece or the bottom piece is formed from a clarified polypropylene material using an injection molding process.

### Claim 20 (depends on 18)

The method of manufacturing a bottle of claim 18, wherein at least one of the top piece or the bottom piece is formed from a clarified polypropylene material using an injection stretch blow molding process.
