A rotary type CVD film forming apparatus for mass production, wherein a film forming chamber is formed by providing one columnar body having a plurality of housing spaces for housing one plastic container each in one said housing space, a plurality of said film forming chambers is arranged on a rotation support body at equal intervals in a circular state, source gas introduction means serving as an external electrode which introduce a source gas that is converted to plasma inside the plastic containers housed in each of said film forming chambers is provided, and high frequency supply means which supply a high frequency to the external electrode of each of said film forming chambers is provided to form a CVD (chemical vapor growing) film on the internal surfaces of said plastic containers.

Rotary type CVD film forming apparatus for mass production

A method and apparatus for cleaning a source gas introduction pipe, which can prevent strong adhesion of contaminant mainly containing carbon powder on an outer surface of the source gas introduction pipe to easily remove the contaminant in a short period of time. While compressed air is sprayed toward the contaminant, the contaminant removed by the spray of the compressed air is exhausted outside a system of a deposition chamber by suction and exhausting device so that the contaminant is not transferred to sides of the deposition chamber and a plastic container in which a CVD film is formed, in a process for extracting the source gas introduction pipe from the plastic container after the CVD film is formed on an inner surface of the plastic container.

Method and device for cleaning raw material gas introduction tube used in CVD film forming apparatus

A plastic container for liquid medicine, which, concerning the effective components of liquid medicine, is capable of prevention of deterioration in quality due to mixing of oxygen and water vapor, prevention of variation in concentration due to water volatilization and moisture absorption, etc. A plastic container for liquid medicine, which is a plastic container internally coated with DLC (diamond-like carbon) film wherein water vapor permeability is 0&#x2013;0.006 g/container/day and oxygen permeability is 0&#x2013;0.011 ml/container/day, such properties being obtained by optimizing the three conditions, composition, density and film thickness of the DLC film.

Plastic container for liquid medicine and method of storing and recovering liquid medicine

A production device for a DLC film-coated plastic container and a production method therefor, capable of forming DLC (diamond-like carbon) films simultaneously on the inner surfaces of a plurality of plastic containers, and reducing variations in film thickness. A production device for DLC film-coated plastic containers, for forming a plurality DLC films simultaneously, characterized by comprising a columnar external electrode () having housing spaces in which a plurality of plastic containers () can be disposed in parallel and independently, internal electrodes () respectively disposed in the housed containers (), a matching box () connected to the external electrode () and impedance-matching a high-frequency load, and a high-frequency power supply () connected to the matching box.
