Patent number: 6223501Abstract: A perforating apparatus for use in the formation of shrink film packages is disclosed. The apparatus comprises a bottom seal tool with a plurality of peninsula regions forming a plurality of window areas. Each pair of window areas has a knife receiving area to receive a knife retaining block. The retaining block contains a perforation knife that extends beyond the surface of the sealing tool a sufficient distance to perforate the packages. At least one screw member extends through the peninsula, contacting the retaining block and securing the retaining block within the retaining channel. A change plate, having slots dimensioned and located to receive the knife blades is placed over the sealing tool surface. The packages are placed on the change plate and sealed by contacting the package with the upper platen. The upper platen is provided with a nonconductive material positioned to receive the knife blade.Type: GrantFiled: November 9, 1999Date of Patent: May 1, 2001Inventor: Wayne Ringer

Patent number: 6167684Abstract: A feeding apparatus for delivering tablets or performs to an encapsulating machine includes a number of vertically extending chutes, each capable of holding a number of tablets aligned in a row along the respective chute. A plunger mechanism temporary engages one of the tablets in the chute so as to prevent downward movement of the tablet and all pills located above it in the chute. A rotatable feed roll is located adjacent a bottom end section of the chutes and this roll has a number of tablet cavities, each capable of holding an individual tablet. Pivotable stop members are used to prevent temporarily downward movement of the bottom pill in each chute, this pill being located downstream of the plunger. These stop members move to a pill releasing position when the plungers are engaging their respective tablets in the chutes. Each stop member prevents downward movement of its respective row of pills in the chute past the stop member when the plunger is moved to a position of disengagement.Type: GrantFiled: January 29, 1999Date of Patent: January 2, 2001Inventor: Aldo Perrone

Patent number: 6167683Abstract: A packaging device for continuously forming and filling a package having a plurality of separate sealed cavities comprises a plastic film winding barrel, a vacuum cavity forming device, a filling means, an aluminum foil winding barrel, a pressing sealing means, and a cutting machine. The vacuum cavity forming device causes the plastic film to be formed with a plurality of cavities. The filling means pumps liquid material into each of the cavities holes. Aluminum foil is adhered to the strip plastic casing by a pressing sealing means. Finally, the cutting machine serves to the cut the strip casing to complete a packaging process.Type: GrantFiled: June 7, 1999Date of Patent: January 2, 2001Assignee: Kyorin Group (China) Ltd.Inventor: Chi Kin Wong

Patent number: 6145284Abstract: A filling machine for thermoplastic cups, with a cyclically operating conveying section which takes over a cup sheet web with thermoformed cups from a thermoforming station, there being provided, for the simultaneous filling of a batch of cups, for each cup of the batch, a filling unit with a filling cylinder and a filling pipe for a pasty filling product, the filling cylinder containing a filling piston on the product side. The technical problem is to provide a filling machine which is easily adjustable in terms of volume, works without a sucking action, and is easy to clean and sterilize. An air piston (31) is connected, on the drive side, to the filling piston (24) by a piston rod (40) and the filling cylinder (23) is closed off above the air piston (31) by a cylinder head (32) which is connected to a pressure compensation reservoir via a compensation pipe (35).Type: GrantFiled: February 2, 1999Date of Patent: November 14, 2000Inventor: Thies Eggers

Patent number: 6138439Abstract: Methods of making slide-zippered reclosable packages are provided. In one embodiment, a pair of opposing film extensions are provided on each package between which a zipper and slider are attached. In another embodiment, sliders are inserted on to zippered packages output from a form-fill-seal machine or the like. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and then a slider is inserted on to the zipper. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and a slider is inserted on to each zipper, either before or after zipper sealing.Type: GrantFiled: May 21, 1999Date of Patent: October 31, 2000Assignee: Illinois Tool Works Inc.Inventors: Michael J.

Patent number: 6119433Abstract: A system and method for sterile packaging of beverages in plastic containers forms the plastic containers and fills them with sterile beverages in a common sterile environment. The containers are formed from a blow molding process in which the containers reach elevated temperatures sufficient to at least in-part sterilize the interior of the containers, are filled with sterile beverages immediately after the containers are formed in the same sterile environment. This eliminates the need for heavy use of sterilizing fluids for the plastic containers such as hydrogen peroxide or the like.Type: GrantFiled: August 27, 1999Date of Patent: September 19, 2000Assignee: The Coca-Cola CompanyInventors: Nobuya Kitahora, Osamu Aoyagi

Patent number: 6109000Abstract: A covering band (12) is pre-heated and then definitively heated in two subsequent areas (P,Z), and is subjected to primary pulling, in an area (T), where the covering band is pulled and applied to a blister band (1), and to secondary pulling in an area (R) which coincides with the pre-heating area (P). The speed of the covering band (12) is lower in the secondary pulling area (R), so as to determine a lengthening which corresponds at least to its maximum lengthening resulting from pre-heating. Cyclical detecting of reference marks (20) printed on the covering band determines temporary reducing of the covering band (12) speed in the secondary pulling point (R), so as to provoke an additional lengthening. The device includes pulling means (5,11) of the blister band (1) and covering band (12), pre-heating means (11) and heating means (13) for the covering band (12), detecting means (16), and driving means (30) acting with different speeds, controlled by the detecting means (16).Type: GrantFiled: December 3, 1998Date of Patent: August 29, 2000Assignee: I.M.A. Industria Macchine Automatiche S.p.A.Inventor: Rino Conti
