Co-injection molded dispensing components
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 dispensing component for use with an urn liner, comprising:
a spout formed of a polyethylene material;
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, wherein the spout includes an adapter that is connected to the tube.
2. The dispensing component of claim 1 , wherein the protrusion is a barb that extends from the spout and that retains the tube to the spout.
3. The dispensing component of claim 1 , wherein the spout includes a flange.
4. The dispensing component of claim 1 , wherein the tube includes an inner layer made of a thermoplastic elastomer material and outer layer that is made of polyethylene.
5. The dispensing component of claim 1 , wherein the spout includes a surface that engages the tube, and at least a portion of the surface is rough.
6. A dispensing component for use with an urn liner, comprising:
a spout formed of a polyethylene material;
an adapter formed of a polyethylene material and a flexible tube formed of a thermoplastic elastomer material, wherein the adapter 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 and wherein the adapter includes a barb that retains the tube thereto; and
corresponding interlocking mechanisms on the spout and the adapter that connect the adapter and spout to each other.
7. The dispensing assembly of claim 6 , wherein the spout includes a flange.
8. The dispensing component of claim 6 , wherein the tube includes an inner layer made of a thermoplastic elastomer material and outer layer that is made of polyethylene.
9. The dispensing component of claim 6 , wherein the adapter includes an inner cavity that receives a portion of the tube to secure the tube to the adapter.
10. The dispensing component of claim 6 , wherein the adapter has a surface that engages the tube, and at least a portion of the surface is rough.
11. A dispensing component for use with an urn liner, comprising:
a spout formed of a polyethylene material;
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 tube includes a protrusion that is retained within a cavity formed in the spout, wherein the spout includes an adapter that is connected to the tube.
12. The dispensing component of claim 11 , wherein the protrusion is a barb that extends from the tube and that retains the tube to the spout.
13. The dispensing component of claim 11 , wherein the spout includes a flange.
14. The dispensing component of claim 11 , wherein the tube includes an inner layer made of a thermoplastic elastomer material and outer layer that is made of polyethylene.
15. The dispensing component of claim 11 , wherein the spout includes a surface that engages the tube, and at least a portion of the surface is rough.
16. A dispensing component for use with an urn liner, comprising:
a spout formed of a polyethylene material;
an adapter formed of a polyethylene material and a flexible tube formed of a thermoplastic elastomer material, wherein the adapter 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, wherein the adapter includes a protrusion and a portion of the elastomer material of the tube forms around the protrusion such that the tube is connected to the adapter; and
corresponding interlocking mechanisms on the spout and the adapter that connect the adapter and spout to each other.
17. The dispensing component of claim 16 , wherein the protrusion is a barb that retains the tube to the adapter.
18. The dispensing assembly of claim 16 , wherein the spout includes a flange.
19. The dispensing component of claim 16 , wherein the tube includes an inner layer made of a thermoplastic elastomer material and outer layer that is made of polyethylene.
20. The dispensing component of claim 16 , wherein the adapter includes an inner cavity that receives a portion of the tube to secure the tube to the adapter.
21. The dispensing component of claim 16 , wherein the adapter has a surface that engages the tube, and at least a portion of the surface is rough.
