Abstract
A polymeric vessel includes a first shell formed from a thermoplastic polymer and including a weld stub, and a second shell formed from the thermoplastic polymer and including a weld anvil matable with the weld stub. The polymeric vessel also includes a friction weld joint joining the weld stub and the weld anvil, and a coupling element interconnecting the first shell and the second shell and spaced apart from the friction weld joint.
Claims19
A polymeric vessel comprising:
- a first shell formed from a thermoplastic polymer and including a weld stub;
- a second shell formed from the thermoplastic polymer and including a weld anvil matable with the weld stub;
- a friction weld joint joining the weld stub and the weld anvil;
- and

A polymeric vessel comprising:
- a first shell having a first arm defining a first outer surface, wherein the first shell is formed from a thermoplastic polymer and includes a weld stub spaced apart from the first arm;
- a second shell having a second arm defining a second outer surface, wherein the second shell is formed from the thermoplastic polymer and includes a weld anvil matable with the weld stub and spaced apart from the second arm;
- a plurality of friction weld joints each spaced apart from one another along the weld stub and joining the weld stub and the weld anvil;
- and
- a coupling element interconnecting the first shell and the second shell and spaced apart from the plurality of friction weld joints, wherein the coupling element includes:
- a spring attached to and disposed between the first arm and the second arm;
- and
- a strap welded to and interconnecting the first outer surface and the second outer surface.
5 more elements
A polymeric vessel comprising:
- a first shell having a first arm defining a first outer surface, wherein the first shell is formed from a polyamide and includes a weld stub spaced apart from the first arm and having a first width of from about 3 mm to about 5 mm;
- a second shell having a second arm defining a second outer surface, wherein the second shell is formed from the polyamide and includes a weld anvil spaced apart from the second arm that is matable with the weld stub and has a second width that is greater than the first width;
- wherein the second width is from about 5 mm to about 7 mm;
- a friction weld joint joining the weld stub and the weld anvil and extending along an entirety of the first width;
- and
- a coupling element interconnecting the first shell and the second shell and spaced apart from the friction weld joint, wherein the coupling element includes a spring attached to and disposed between the first arm and the second arm.
