A device for treating hollow bodies, comprising at least a nozzle and a circuit for setting a pressurized airflow in circulation, having a valve and a first pressure sensor measuring a first pressure; a control distributor of said valve; a line connecting said distributor to said valve; a control unit with a time measurement component; wherein said device comprises a second pressure sensor situated along said line, measuring a second pressure, and wherein said control unit comprises means that are able to determine a differential between the measurement of the first pressure and the measurement of the second pressure as a function of time. The invention also relates to a corresponding treatment method.

Ways for simultaneously forming and filling a container with a liquid product are provided that include a mold cavity, a dispensing means, a blow nozzle, a conduit, and a hydrophobic surface. The mold cavity defines an internal surface and accepts a preform. The dispensing means receives the liquid product and dispenses a charge of the liquid product. The blow nozzle transfers the charge of the liquid product dispensed from the dispensing means into the preform to urge the preform to expand toward the internal surface of the mold cavity and form a resultant container. The liquid product remains within the container as an end product. The conduit fluidly couples the dispensing means to the blow nozzle. The hydrophobic surface contacts the liquid product when the system simultaneously forms and fills the container, where the hydrophobic surface forms part of the dispensing means, the blow nozzle, and/or the conduit.

A preform coating device is provided with: a rotational holding part that horizontally holds a preform and rotates the preform about the axis of the preform, and that grasps a spout of the preform; a conveyance part that conveys the preform by moving the rotational holding part; a dispenser that discharges a coating liquid toward the preform; a preform support part that supports the bottom-side end of the cylindrical barrel of the preform while the dispenser is discharging the coating liquid; and a spout support part that supports the outer circumferential surface of the spout of the preform while the dispenser is discharging the coating liquid.

A method of manufacturing a fluidic actuator that comprising generating a member that includes a web and a pair of cavities and closing the cavities by closing one or more respective openings of the cavities to generate a first closed bladder and a second closed bladder.
