Abstract

Systems and apparatuses include a tubular body of a garden hose assembly. The tubular body includes an inner tube including an inner surface and an outer surface, wherein the inner surface defines an interior passageway of the garden hose assembly. The tubular body further includes an outer tube including an inner surface and an outer surface, wherein the inner surface surrounds the outer surface of the inner tube. The tubular body further includes a reinforcement layer including a helical pattern spiraling in at least one direction around the outer surface of the outer tube. The tubular body further includes an inner cover including an inner surface and an outer surface, wherein the inner surface surrounds the reinforcement layer. The tubular body further includes an outer cover including an inner surface and an outer surface, wherein the inner surface surrounds the outer surface of the inner cover.

First claim

What is claimed is:

1. A garden hose assembly comprising:
an inner tube including an inner tube inner surface and an inner tube outer surface, wherein the inner tube inner surface defines an interior passageway of the garden hose assembly;
an outer tube including an outer tube inner surface and an outer tube outer surface, wherein the outer tube inner surface surrounds the inner tube outer surface;
a reinforcement layer including a helical pattern spiraling in at least one direction around the outer tube outer surface;
an inner cover including an inner cover inner surface and an inner cover outer surface, wherein the inner cover inner surface surrounds the reinforcement layer; and
an outer cover including an outer cover inner surface and an outer cover outer surface, wherein the outer cover inner surface of the outer cover surrounds the inner cover outer surface,

wherein the inner tube comprises a base thermoplastic material and is substantially free from tubes additives, and
wherein the base thermoplastic material of the outer tube comprises at least one additive.

2. The garden hose assembly of claim 1 , defining a substantially flattened shape.

3. The garden hose assembly of claim 1 , wherein the reinforcement layer allows expansion from a substantially flattened shape to a substantially circular shape in reaction to internal pressure in the interior passageway.

4. The garden hose assembly of claim 1 , wherein the reinforcement layer includes a first reinforcement layer and a second reinforcement layer.

5. The garden hose assembly of claim 1 , wherein the inner tube outer surface is bonded to the outer tube inner surface.

6. The garden hose assembly of claim 1 , wherein the inner cover outer surface is bonded to the outer cover inner surface.

7. The garden hose assembly of claim 1 , wherein the outer tube outer surface is bonded to the inner cover inner surface.

8. The garden hose assembly of claim 1 , further comprising a fitting configured to attach to a first end of the garden hose assembly and including:
a shank,
a threaded portion,
a spring arranged at least partially within the tubular body, and
a ferrule surrounding the shank and structured to capture the spring.

9. The garden hose assembly of claim 8 , wherein the spring is a tapered spring directly coupled to the shank and positioned at least partially within the inner tube.

10. The garden hose assembly of claim 8 , wherein the shank includes a spring engaging feature shaped to engage and retain the spring in cooperation with the ferrule.

11. The garden hose assembly of claim 1 , wherein a thickness of the outer tube is between about 0.010 and 0.030 inches.

12. The garden hose assembly of claim 1 , wherein a thickness of the outer cover is between about 0.010 and 0.030 inches.

13. A garden hose assembly comprising:
a tubular body including:
a tube defining an interior passageway of the garden hose assembly and comprising a base thermoplastic material, wherein the tube includes an inner tube and an outer tube,

wherein the outer tube comprises at least one tube additive to the base thermoplastic material and the inner tube is substantially free from tube additives;
a reinforcement surrounding the tube; and
a cover surrounding the reinforcement comprising the base thermoplastic material and at least one cover additive,

wherein the tubular body has a substantially flattened shape.

14. The garden hose assembly of claim 13 , wherein the cover comprises an inner cover and an outer cover,
wherein the outer cover comprises the cover additive to the base thermoplastic material, and
wherein the inner cover is substantially free of cover additives.

15. The garden hose assembly of claim 13 , wherein the reinforcement includes a one-thousand (1000) denier twisted strand yarn.

16. The garden hose assembly of claim 13 , further comprising a fitting configured to attach to a first end of the tubular body and including
a shank,
a threaded portion,
a spring arranged at least partially within the tubular body, and
a ferrule surrounding the shank and structured to capture the spring.

17. A method comprising:
co-extruding a tube including a base thermoplastic material and comprising an inner tube and an outer tube, wherein the outer tube comprises the base thermoplastic material and at least one tube additive;
applying a reinforcement to the tube;
extruding a cover over the tube and reinforcement, the cover comprising the base thermoplastic material and at least one cover additive; and
flattening the cover, reinforcement, and tube after extruding the cover and before the cover has cooled.

18. The method of claim 17 , wherein flattening occurs when the cover is not fully cooled.
