Co-injection molded dispensing components method
A present application relates to a dispensing component for use with an urn liner. The dispensing component includes a spout formed of a polyethylene material and a flexible tube formed of a thermoplastic elastomer material. The spout and tube are formed together as a single component in a mold by co-injection of the polyethylene material and the thermoplastic elastomer material.
1. A method for assembling a liner for a beverage urn, comprising:
providing a plastic bag;
providing a dispensing component that includes a spout formed of a polyethylene material and a flexible tube formed of a thermoplastic elastomer material, wherein the spout and tube are formed together as a single interconnected component in a mold by co-injection of the polyethylene material and the thermoplastic elastomer material such that the spout includes a protrusion that is retained within a cavity formed in the tube;
cutting a hole in the plastic bag;
inserting the dispensing component into the hole; and
heat sealing the plastic bag to the spout.
2. A method for assembling a liner for a beverage urn, comprising:
providing a plastic bag;
providing a spout made of polyethylene;
providing a dispensing component that includes a spout adapter formed of polyethylene and a flexible tube formed of thermoplastic elastomer, wherein the spout adapter and tube are formed together as a single component in a mold by co-injection of the polyethylene and the thermoplastic elastomer such that the spout adapter includes a protrusion that is retained within a cavity formed in the tube;
cutting a hole in the plastic bag;
inserting the spout into the hole;
heat sealing the plastic bag to the spout; and
connecting the adapter to the spout.
