Abstract
An apparatus for treating a package container blank with a fluid is disclosed and includes a rotary portion provided with a plurality of chambers for receiving the blanks and a fixed portion having a stator surface that faces the rotary portion. The fixed portion is provided with an arrangement that opens to the stator surface for supplying fluid so that upon successive rotations of the rotary member, the chambers will successively align with the arrangement for supplying fluid so that fluid is thereby supplied to the chambers.
Claims16
An apparatus for treating package container blanks with a fluid, comprising:
- a rotary portion mounted for rotation about a drive shaft and having a chamber mounted thereon for receiving a package container blank, and a fixed portion extending around said drive shaft and having a stator surface that faces the rotary portion, said rotary portion being rotatable relative to said fixed portion and said rotary portion having a rotor surface that faces said fixed portion, said rotor surface and said stator surface being substantially conical, said fixed portion having a first inlet channel formed therein, conduit means in said rotary portion for interconnecting said first inlet channel and said chamber at a first rotary position of said rotary portion, said fixed portion having an infeed aperture opening to the stator surface, said chamber being aligned with said infeed aperture when said rotary portion is in a second rotary position so that container blanks may be inserted into said chamber through said infeed aperture when said rotary portion is in the second rotary position and fluid may be supplied through said conduit means to said chamber upon rotation of said rotary portion to said first rotary position.
An apparatus for treating package container blanks with a fluid, comprising:
- a rotary portion having a plurality of package container blank receiving chambers provided thereon, said rotary portion having a rotor surface and said plurality of package container blank receiving chambers opening to said rotor surface;
- and
- a fixed portion having a stator surface that faces the rotor surface, said rotary portion being rotatable relative to said fixed portion and said fixed portion having a plurality of treatment stations, each treatment station being alignable with at least one of said package container blank receiving chambers, said fixed portion having infeed means at a first one of said treatment stations for permitting a package container blank to be inserted into one of the package container blank receiving chambers when the rotary portion is rotated so that the one package container blank receiving chamber is in an infeed position, said fixed portion having means for preheating a package container blank in one of the package container blank receiving chambers at a second one of said treatment stations, said fixed portion having means for sterilizing a package container blank in one of the package container blank receiving chambers at a third one of said treatment stations, and said fixed portion having means for discharging a package container blank from one of the chambers at a fourth one of said treatment stations, wherein when the rotary portion is rotated sequentially through the first, second, third and fourth treatment stations a package container blank in inserted into one of the package container blank receiving chambers, is efficiently and effectively treated and is discharged from the package container blank receiving chamber.
A method of treating package container blanks with a fluid, comprising the steps of:
- aligning a chamber provided on a rotary portion with an aperture extending through a fixed portion;
- inserting a package container blank through the aperture and into the chamber;
- rotating the rotary portion relative to the fixed portion to bring the chamber into communication with an inlet channel provided in the fixed portion;
- and
- supplying fluid through the inlet channel and to the chamber to treat the package container blank.
