A cap attachment device includes a cap holder, a vial platform, a cap pushing rod and a driver. The cap holder is provided to be liftable and lowerable between a first height and a second height lower than the first height, and holds a cap plate holding a cap. The vial platform is provided below the cap holder. On the vial platform, a vial plate holding a snap vial corresponding to a cap is placed. The cap pushing rod is provided above the cap holder and extends in an up-and-down direction. When the cap holder is at the second height, the driver lifts and lowers the cap pushing rod such that the cap pushing rod pushes a cap held by the cap plate downwardly.

The invention relate generally to a tightening mechanism for a bottle filling and capping system, and a bottle neck configuration. More specifically, the invention includes a machine for tightening plastic caps onto the threaded necks of plastic bottles, and bottle neck configuration that facilitates the capping process, both of which result in a simple and effective capping operation. A conveying assembly moves the bottle in a circular path where the neck of the bottle and the cap are brought together by moving the bottle under a cap that is loosely held at a particular elevation and angle by a feeder mechanism. The conveying system constricts the rotational movement of the bottle, and a neck support stabilizes the neck of the bottle vertically, as the cap is pressed onto the neck initially by a roller. A capping station in a bottle filling line is comprised of a spring biased toothed finger that engage the peripheral edge of the caps as the bottles are conveyed through the machine. Depending on various factors such as the number and circumferential length of the threads on the cap and bottle a second roller and second toothed finger will be used to complete the tightening process. When a capped bottle exits the capping station, the cap is fully engaged with the bottle in that it is tightened and in its final position relative to the bottle.

A bottle holder that automatically seals a bottle opening when the bottle holder is placed for storage. The bottle may rest within a recess of the holder base, and the nozzle of the bottle is held in place by a nozzle catch that is conically shaped and has an inner cup that tapers to a terminal point so that a nozzle that it placed within will be sealed by the inner wall of the cup. The nozzle catch is spring loaded and presses down against the bottle to hold it in place and maintain a seal on the nozzle. A bottle may be placed in the holder by positioning a nozzle in the nozzle catch on the upper side of the holder and pushing upwards and inwards, which causes the spring to compress and allows the bottle bottom to pass over the base and into the recess.

A bottle cap opening and closing device and an experimental apparatus. The bottle cap opening and closing device includes a base, a bottle body clamping mechanism used for clamping a bottle body, a first buffer mechanism arranged between the bottle body clamping mechanism and the base, a bottle cap clamping mechanism arranged opposite the bottle body clamping mechanism and is used for clamping a bottle cap, and a rotation driving mechanism drive-connected to the bottle body clamping mechanism and drives the bottle body clamping mechanism to rotate relative to the bottle cap clamping mechanism to enable the bottle body and the bottle cap to be relatively tightened or separated from each other.

A capping machine for applying a cap on an open end of a container that is made of a deformable material and filled with a pourable product is disclosed. The machine comprises a conveying device and at least one operative unit moved by the conveying device along a processing path. The at least one operative unit comprises a support portion configured to receive and retain a container, and at least one capping head movable to and away from the open end of the container to apply the cap onto the open end of the container. The at least one operative unit further comprises a plunger movable to and away from an opposite closed end of the container to deform the closed end of the container so as to reduce an interior volume of the container and to increase an interior pressure of the container.
