Patent number: 5480025Abstract: Step-shaped innerframes and blanks for forming such innerframes are provided to permit shorter than conventional cigarettes to be packaged in a conventionally sized hinged lid box. A front panel is foldably connected to a substantially perpendicular step bottom panel which in turn is foldably connected to a substantially perpendicular back panel, such that the front and back panels extend in opposite directions and lie in substantially parallel planes to form an integral step configuration. When the inner frame is located within a hinged lid box, a receptacle is formed for a short cigarette bundle. A lower receptacle is defined below the step bottom panel to store discarded cigarettes which are inserted into the lower receptacle via a hole located in one of the box walls and any associated underlying innerframe panel.Type: GrantFiled: December 6, 1993Date of Patent: January 2, 1996Assignee: Philip Morris IncorporatedInventors: James B.

Patent number: 5468266Abstract: A carbonaceous heat source comprising metal oxides and methods for making such heat source are provided. The heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time produces virtually no carbon monoxide upon combustion. The heat source is prepared by pre-forming the carbon and binder materials into a desired shape, and then treating the shape with a sol containing metal oxide precursors. The metal oxide precursors are deposited in the pre-formed carbon shape. Further treatment converts the deposited metal oxide precursors into metal oxide.Type: GrantFiled: June 2, 1993Date of Patent: November 21, 1995Assignee: Philip Morris IncorporatedInventors: Azzedine Bensalem, Sarojini Deevi, Seetharama C.

Patent number: 5448365Abstract: Improved systems for optical inspection are provided. The improved systems use modified camera boxes to provide increased, and more uniform, illumination of the objects being inspected through the use of illuminator windows. The lens arrangement of the improved camera boxes is contained within a self-contained, sealed housing that is separate from the camera to prevent particle contamination of the lens arrangement and provide improved flexibility during installation of the camera boxes on the inspection systems. The self-contained housing also provides for a reduction in the space required for the camera boxes. The light receiver of the housing is provided with the capability for preventing particle contamination of the receiver itself.Type: GrantFiled: August 17, 1993Date of Patent: September 5, 1995Assignee: Philip Morris IncorporatedInventors: Gary E.

Patent number: 5447014Abstract: A cigarette packing machine exit apparatus having a contoured heating surface and a pivoted heater retraction feature. The contoured surface preferably is in the form of diagonally oriented elongated narrow ridges that act as contact surfaces to concentrate heat on the seal of the cigarette packs being conveyed along the surface. The pivoted retraction feature serves to raise and then lower the heater when the packing machine is shut off so that the packs then on the heater surface are raised and are held spatially separated from the heater.Type: GrantFiled: June 23, 1993Date of Patent: September 5, 1995Assignee: Philip Morris IncorporatedInventors: John M. Adams, Jeffrey M. S. Haskin

Patent number: 5432600Abstract: The entire cylindrical surface of a cylindrical object such as a cigarette is optically inspected by first inspecting at least 180.degree. of the circumference of a first side of the surface, and then inspecting at least 180.degree. of the circumference of the other side. Each of the inspection stations illuminates more than 180.degree. of the circumference and images the surface from two angularly spaced directions to ensure that at least 180.degree. of the circumference is seen at each station. Any object having a defective image is automatically rejected from the apparatus, and the images and other statistical information regarding the performance of the system are displayed by the system. The images are formed in such a way as to greatly increase the speed at which the inspection system operates so that it can keep up with the very high rates at which objects such as cigarettes are made in modern machinery (e.g., approximately 10,000 cigarettes per minute).Type: GrantFiled: March 24, 1994Date of Patent: July 11, 1995Assignee: Philip Morris IncorporatedInventors: Gary Grollimund, H. Cary Longest, Jr., Barry S. Smith

Patent number: 5385526Abstract: The blanks (1) are withdrawn one after another from a storage part (20) by transfer means (21) and are disposed on the cylindrical support surface of a drum (3) driven rotatingly by portions of a revolution. Various processing operations are performed on the blanks either while the drum is rotating or while it is stopped, e.g., folding a flap (16), gluing this flap to a surface portion (15) of the blank, or printing a code (17) on part of the blank. The presence, correct positioning, and proper alignment of the blank on the drum are checked before the aforementioned operations are carried out. After they have been effected, the blank is withdrawn from the drum to be sent on to a packaging machine. The processing apparatus and method can be utilized on a line for processing boxes or the like, particularly cigarette boxes, just before they are assembled to receive their contents.Type: GrantFiled: February 22, 1994Date of Patent: January 31, 1995Assignee: Fabriques de Tabac Reunies, SAInventors: Albert Sigrist, Roberto Rizzolo

Patent number: 5383479Abstract: A process for reordering tobacco wherein tobacco is contacted with an air stream having a relative humidity near the equilibrium conditions of the tobacco. As the OV content of the tobacco increases, the relative humidity of the air stream contacting the tobacco is increased to effect reordering of the tobacco. Also provided is a process for drying tobacco, wherein tobacco is contacted with an air stream having a relative humidity near or below the equilibrium conditions of the tobacco. As the OV content of the tobacco decreases, the relative humidity of the air stream contacting the tobacco is decreased to effect drying of the tobacco. Tobacco is reordered or dried according to the processes of the present invention in a continuous manner preferably using a self-stacking spiral conveyor.Type: GrantFiled: October 30, 1992Date of Patent: January 24, 1995Assignee: Philip Morris IncorporatedInventors: Warren D. Winterson, John C. Crump, III, Eugene B. Fischer

Patent number: 5377905Abstract: The packaging box is made from a one-piece blank and comprises a receptacle portion and a lid portion bounded by perforation lines made in the receptacle portion. A closure flap is fixed to the lid portion. The box is opened for the first time by acting upon this flap to separate the perforated lid portion from the rest of the receptacle portion. When the box is reclosed, the lid portion is kept shut by inserting the closure flap into the box. The packaging box is fluid-tight after manufacture so that no additional wrapping sheet is needed. The blank may be made of thin cardboard and may be provided with a self-sealing coating.Type: GrantFiled: August 11, 1993Date of Patent: January 3, 1995Assignee: Philip Morris IncorporatedInventor: Albert Sigrist

Patent number: 5366077Abstract: A pack has a retention member formed in the walls of the innerframe and the lid. The retention member can be tab-like extension members extending from a top edge of the innerframe and the bottom edge of the lid. When the tab-like extension member is folded into operational position, it functions to help keep the lid closed by providing additional interference between the lid and the innerframe. The retention member can also be segments of inner wall panels of the lid itself. When folded into operational position, the folded segment of the inner wall panel functions to help keep the lid closed by providing additional interference between the lid and the innerframe. Any of these retention members can be folded into operational position by the manufacturer. Alternatively, the pack can be provided to the consumer with the extension member in non-operational position, leaving to the individual consumer's discretion the decision to fold the retention member into operational position.Type: GrantFiled: July 20, 1993Date of Patent: November 22, 1994Assignee: Philip Morris IncorporatedInventor: Xuan M.
