International Classification:

B67D 554
B67D 500

US Classification:

137606

Abstract:

A dual-stream filling system is used in a packaging machine to introduce at least two flowable materials into a plastic bottle. The dual-stream filling system defines a material flow path therethrough. The system includes a primary filling tube having an inlet end and a discharge end and defining a primary filling tube internal flow region. A secondary filling tube has an inlet end and an outlet end and defines a secondary filling tube internal flow region. The secondary filling tube is positioned at least in part within the primary filling tube internal flow region, penetrating the primary filling tube through the first opening. The dual-stream fill system includes a valve plug that includes a portion that is movable relative to the secondary filling tube between an opened state wherein flow communication is established between the internal flow regions of the primary and secondary filling tubes and a closed state wherein flow communication is terminated between the internal flow regions of the primary and secondary filling tubes. An actuator is provided for moving the valve plug portion between the opened and closed positions. The actuator is disposed fully external of the secondary filling tube flow region.

International Classification:

F16K1/54

US Classification:

137613

Abstract:

A controlled flow filling system is used with a flowable product filling apparatus. The filling system includes a first, upstream V-track valve in series with a second, downstream umbrella valve to provide a substantially paraboloid liquid flow profile of the fluid while filling an associated container. The filling system is configured such that a substantial portion of the pressure drop associated with the flowing fluid occurs at the V-track valve cone to reduce spraying and loss of the fluid product at the umbrella valve. The filling system is used in a filling apparatus that uses pumps or a pressured gas blanket to provide motive force to drive the fluid through the apparatus.

Bengt Andersson - Palatine IL
Yutaka Kaneko - Wheeling IL

Assignee:

Tetra Laval Holdings & Finance, SA - Pully

International Classification:

B65B 104

US Classification:

141 91

Abstract:

The fill system provides sterile air to the product tank and the cleaning box which creates a more hygienic environment for the forming, filling and sealing of cartons on a packaging machine. The fill system has a pair of offset reducers for facilitated positioning of the fill pipes in relation to each other. The fill system also has a tank atmospheric valve for maintaining the proper pressure in the product tank. The fill system also has a level probe for measuring the level of product in the product tank during a production cycle, and to measure the level of cleaning solution in the product tank during a cleaning cycle.

International Classification:

B65B 300

US Classification:

222 64

Abstract:

A system to be utilized at a dairy in the distribution of a pumpable food product from a storage tank to a filling machine for dispensing into containers. The system includes a balance tank for storing the product on the filling machine. The balance tank is in flow communication with a storage tank via a product line, and also has a level probe for monitoring the amount of product in the tank. A product pump pumps the food product to a valve mechanism which is also disposed on the product line. A programmable logic controller receives a signal from the probe indicative of the level of the product in the balance tank, and generates a series of signals to the product pump and the valve mechanism to maintain a steady flow of product from the storage tank to the balance tank. In this manner, foaming of the product in the balance tank is eliminated or substantially reduced to acceptable levels.

International Classification:

B65B 300

US Classification:

141 51

Abstract:

An apparatus for internally venting a product tank in a packaging machine is set forth. The apparatus includes a filling tube having a first end extending from a first opening of the product tank. The apparatus further includes an air collection mechanism having a filling tube opening adapted to receive a second end of the filling tube. The air collection mechanism extends below the second end of the filling tube. A vent pipe is connected to a second opening of the product tank and to a vent pipe opening in the air collection mechanism. The filling tube and the vent pipe are separately connected to both the product tank and the air collection mechanism. Air pressure, arising from operating the packaging machine, directs air from the air collection mechanism through the vent pipe and into the product tank. Such air proceeds through the vent pipe and replaces product in the product tank as the product is dispersed into the carton during filling.

Assignee:

Tetra Laval Holdings & Finance, SA - Pully

International Classification:

B65B 304

US Classification:

141 90

Abstract:

A cleaning box for a liquid food product filling apparatus includes a mounting member from which the plurality of filling tubes depend, and a hollow, shroud-like elliptical cylindrical body extending from the mounting member. The cleaning box is configured to, in part, shroud the filling tubes. The elliptical cylindrical body has a longitudinal axis, and is mounted to the mounting member so as to define an elliptical juncture therebetween. The elliptical cylindrical body terminates at about a free end of the filling tubes so as to define an opening. The opening is formed at an angle relative to the longitudinal axis so as to define a circular end profile. The opening is further formed such that the filling tubes are visually perceptible from a plane perpendicular to the longitudinal axis.
