Abstract
An apparatus, system, and method for dispensing fluid into containers includes a cleaning mechanism that brings the discharge nozzle of a dispenser into the travel path of a film web so that the end-face can make contact with the film web to remove from the end-face at least a portion of any fluid or reaction-products of the fluid that may be in adherence with the end-face. A film for removing such fluid or reaction-products from the end-face of the dispenser is also provided.
Claims35
An apparatus for dispensing fluid into containers, comprising:
- a. a mechanism that conveys a web of film along a predetermined path of travel and converts the film into one or more containers;
- b. a dispenser through which fluid may flow in predetermined amounts, said dispenser positioned adjacent the travel path of the film web such that said dispenser is capable of dispensing fluid into the containers, said dispenser having a discharge nozzle comprising an end-face and a discharge port disposed in said end-face, wherein fluid exits said dispenser through said discharge port;
- and
- c. a cleaning mechanism that brings said discharge nozzle of said dispenser into the travel path of the film web so that said end-face can make contact with the film web to remove from said end-face at least a portion of any fluid or reaction-products of the fluid that may be in adherence with said end-face.
A system for dispensing fluid into containers, comprising:
- a. a web of film;
- b. a mechanism that conveys said film web along a predetermined path of travel and converts said film web into one or more containers;
- c. a fluid source containing therein a fluid;
- d. a dispenser in fluid communication with said fluid source and being positioned adjacent the travel path of the film web to dispense a predetermined amount of said fluid into the containers, said dispenser having a discharge nozzle through which said fluid flows into the containers, said discharge nozzle comprising an end-face and a discharge port disposed in said end-face, said fluid exiting said dispenser through said discharge port;
- and
- e. a cleaning mechanism that brings said discharge nozzle of said dispenser into the travel path of said film web so that said end-face makes contact with said film web to remove from said end-face at least a portion of any fluid or reaction-products of said fluid that may be in adherence with said end-face.
A method for dispensing fluid into containers, comprising:
- a. providing a web of film;
- b. conveying said film web along a predetermined path of travel and converting said film web into one or more containers;
- c. providing a fluid source containing therein a fluid;
- d. dispensing a predetermined amount of said fluid into the containers from a dispenser that is in fluid communication with said fluid source and is positioned adjacent the travel path of the film web, said dispenser having a discharge nozzle through which said fluid flows into the containers, said discharge nozzle comprising an end-face and a discharge port disposed in said end-face, said fluid exiting said dispenser through said discharge port;
- and
- e. removing from said end-face at least a portion of any fluid or reaction-products of said fluid that may be in adherence with said endface by bringing said discharge nozzle of said dispenser into the travel path of said film web so that said end-face makes contact with said film web.
A film web that is conveyable along a predetermined path of travel, convertible into one or more containers, and capable of enclosing within the containers a polyurethane foam that forms within the containers as the reaction-product of two or more foam precursors, the precursors being dispensed into the containers separately or as a mixture by at least one dispenser having a discharge nozzle through which the precursors flow into the containers, the discharge nozzle comprising an end-face and a discharge port disposed in the end-face, said film web comprising one or more materials incorporated into said film web or adhered to a surface of said film web such that, when said film web is brought into contact with the end-face, at least a portion of any precursors or reaction-products thereof that may be in adherence with the end-face are removed therefrom.
