## CPC

- B67B 3/206: {Means for preventing rotation of the container or cap}
- B67B: APPLYING CLOSURE MEMBERS TO BOTTLES JARS, OR SIMILAR CONTAINERS; OPENING CLOSED CONTAINERS (opening or closing devices attached to, or incorporated in, containers or container closures B65D)

## Abstract

The use of a frictional engagement with the top and/or side of a lifter ring on the neck of a bottle for controlling the rotation of the bottle during the capping process. The frictional engagement may be used to hold the bottle steady during the capping process or may be utilized to cause counter rotation of the bottle during the capping process. A method and apparatus for using counter rotation of the bottle to apply a cap to a bottle is also described.

## Claims

### Claim 1

A bottle control apparatus adapted to control the rotation of a bottle during the mounting of a cap onto the bottle, the bottle having a lifter ring with an upper surface, a side surface, and a bottom surface, the apparatus comprising:
a frictional engagement groove adapted to frictionally engage the lifter ring; and
a lifter ring slide support adapted to slideably support bottom surface of the lifter ring;
wherein one of the frictional engagement groove and the lifter ring slide support moves in relation to the other to cause rotation of the bottle.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the frictional engagement groove is adapted to contact the upper surface of the lifter ring.

### Claim 3 (depends on 2)

The apparatus of claim 2, the frictional engagement groove is adapted to contact the side surface of the lifter ring.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the frictional engagement groove is hingably mounted on a frame, the apparatus further comprising:
a biasing spring rotatably mounted to the frame and adapted to bias the groove against the lifter ring.

### Claim 5

A bottle control apparatus adapted to control the rotation of a bottle during the mounting of a cap onto the bottle, the bottle having a lifter ring with an upper surface, a side surface, and a bottom surface, the apparatus comprising:
a frictional engagement groove adapted to contact the upper surface of the lifter ring; and
a lifter ring slide support adapted to move in relation to the frictional engagement groove;
wherein the frictional engagement groove and lifter ring slide support are adapted to cause a rotation of the bottle.

### Claim 6

A bottle control apparatus adapted to control the rotation of a bottle during the mounting of a cap onto the bottle, the bottle having a lifter ring with an upper surface, a side surface, and a bottom surface, the apparatus comprising:
a frictional engagement groove rotationally mounted to a frame,
a biasing spring connected to the frame and adapted to bias the groove against the lifter ring;
a lifter ring slide support adapted to move in relation to the frictional engagement groove; and
wherein the frictional engagement groove and lifter ring slide support are adapted to cause a rotation of the bottle.
