Patent number: 4997014Abstract: A modular fill assembly is provided for use on a filling machine. The assembly defines a plurality of individual product discharge flow paths each communicating with a common supply. A plurality of fill nozzles are carried by the assembly for each filling a separate container. Individual valves for each flow path are each operable between an open configuration permitting the flow of the product through the associated flow path and a closed configuration occluding the associated flow path. Each valve has a separate actuator for operating the associated valve independently of the other valves.Type: GrantFiled: September 14, 1989Date of Patent: March 5, 1991Assignee: Automatic Liquid Packaging, Inc.Inventors: Gerhard H. Weiler, Dieter H. Nagel

Patent number: 4584823Abstract: A method and apparatus for blow molding in a single form-fill-seal operation a droplet dispenser bottle which delivers fluid in precise, uniform drops rather than the streamlets produced by similar bottles of earlier design. The method and apparatus is such that the desired amount of fluid is dispensed from the bottle regardless of how hard the bottle is squeezed. Depending on the needs of the packager, the method and apparatus can be made to form the orifice to precisely control droplet size and/or weight. The droplet dispenser bottle can be molded in virtually any shape desired to hold up to approximately two ounces of fluid.Type: GrantFiled: March 11, 1985Date of Patent: April 29, 1986Assignee: Heinz Plastic Mold Co.Inventor: Dieter H. Nagel

Patent number: 4463867Abstract: A thermoplastic container which is blown, filled and hermetically sealed in a single forming and filling operation. The removable cap integrally formed therewith normally hermetically seals the container and has a peripheral side wall, a horizontal flange portion which merges with the neck portion and an annular groove which is formed in the horizontal flange portion and provides a weakened severing line for removing the cap. A pull tab having a narrow in width, vertically disposed tab flange is integrally connected with the horizontally extending flange portion and has means for gripping the pull tab to pivotally manipulate the pull tab outwardly from the container. The pull tab on being pivotally manipulated causes the horizontally extending flange portion to sever at the annular groove, thereby permitting the cap to be removed from the container.Type: GrantFiled: August 19, 1983Date of Patent: August 7, 1984Assignee: Heinz Plastic Mold Co.Inventor: Dieter H. Nagel

Patent number: 4337025Abstract: A mold assembly is provided for making a thermoplastic container having a bottom, side and unitary closure or top wall means with a parting line along a plane of symmetry in the bottom and sidewall means but with the parting line offset on the top wall means to define a generally flat, pierceable membrane on a major portion of the exterior surface of the top wall means. The mold assembly molds and seals the container from a tube of thermoplastic material, which assembly includes mold parts having lower sections adapted to open and close relative to a center parting plane to shape the bottom and sidewall means of the container and having a pair of upper sections adapted to shape the unitary closure. One of the upper sections has a removable protuberance for forming a major portion of the container top closure surface with the mold parting line thereon offset relative to the center parting plane of the mold assembly.Type: GrantFiled: August 25, 1980Date of Patent: June 29, 1982Assignee: Automatic Liquid Packaging, Inc.Inventors: Louis T. Pagels, Dieter H. Nagel

Patent number: 4258867Abstract: A hermetically sealed container is provided with a neck portion having an end wall defining a container contents-dispensing aperture therein. The aperture is closed with a removable cap structure connected with a frangible web unitary with the end wall and cap so as to seal the container contents-dispensing aperture. An overcap is rotatably mounted on the container and has a cage for matingly engaging the cap and is adapted to break the frangible web when the overcap is rotated.Type: GrantFiled: March 19, 1979Date of Patent: March 31, 1981Assignee: Automatic Liquid Packaging, Inc.Inventors: Gerhard H. Weiler, Dieter H. Nagel

Patent number: 4226334Abstract: A stopper is provided which is adapted to be held in place in an opening in a molded thermoplastic container that is molded about the stopper in place. The stopper has a substantially cylindrical body portion with a planar end surface at one end thereof and a unitary skirt portion depending from the other end of the body portion. An annular flange, unitary with the body portion, extends laterally away from the body portion in one end thereof to define first and second peripheral flange surfaces and a lateral flange surface. The first peripheral flange surface is contiguous with the planar end surface and with the lateral flange surface. The first peripheral flange surface further is disposed at an angle with respect to the planar end surface and converges towards the second peripheral flange surface in a direction away from the body portion. The second peripheral flange surface is contiguous with the lateral flange surface and the skirt portion.Type: GrantFiled: December 14, 1978Date of Patent: October 7, 1980Assignee: Automatic Liquid Packaging, Inc.Inventors: Gerhard H. Weiler, Dieter H. Nagel

Patent number: 4178976Abstract: A unitary, hermetically-sealed but pierceable dispensing container, suitable for packaging parenteral solutions, is made from a flexible, generally tubular body of thermoplastic material utilizing a form, fill and seal technique and a movable, composite mandrel that includes a forming ram member for compression molding from within the container a container wall portion which includes a pierceable membrane. The tubular body is closed at one end and terminates at the other end in a draining region having an access aperture or port sealed by a unitary membrane of predetermined thickness. The membrane permits penetration of a cannula therethrough without coring, and an annular sealing means surrounding the aperture is adapted for frictional and sealing engagement of the cannula after the membrane has been penetrated.Type: GrantFiled: October 16, 1978Date of Patent: December 18, 1979Assignee: Automatic Liquid Packaging, Inc.Inventors: Gerhard H. Weiler, Dieter H. Nagel, Louis T. Pagels
