Abstract

A composite barrel for storing wine comprising a polymer body, at least one removable wooden head for attachment to an end of the polymer body, each wooden head having an interior surface, the interior surface configured to increase the surface area of the interior surface of the wooden head for contact with wine to be stored, and a sealing mechanism for sealingly securing each removable wooden head to the polymer body. A wooden head may be used at both ends of the barrel for sealing the barrel and bringing more wood into contact with the contents of the barrel.

Claims

1. A composite barrel for storing a liquid, the composite barrel comprising:

a polymer body having an open end;

a wooden head attachable to the open end of the polymer body, the wooden head having an interior surface configured to increase surface area for contact with the liquid and an exterior surface; and

a sealing mechanism for sealingly securing the wooden head to the polymer body.

2. The composite barrel of claim 1, wherein interior surface of the wooden head comprises a region of channels.

3. The composite barrel of claim 2, wherein the region of channels comprises cross-hatch channels formed in the interior surface of the wooden head.

4. The composite barrel of claim 2, wherein the region of channels comprises linear T-channels formed in the interior surface of the wooden head.

5. The composite barrel of claim 2, wherein the region of channels comprises linear U-channels formed in the interior surface of the wooden head.

6. The composite barrel of claim 2, wherein the wooden head includes wooden planks.

7. The composite barrel of claim 6, wherein the wooden planks are at least partially comprised of an oak wood.

8. The composite barrel of claim 1, wherein the exterior surface of the wooden head comprises a region of channels.

9. The composite barrel of claim 1, wherein the sealing mechanism comprises:

an annular flange on the open end of the polymer body, the annular flange having an interior surface;

an outer ring connectable with the interior surface of the annular flange for seating the wooden head;

an inner ring nestable in the outer ring against an exterior surface of the wooden head; and

an attachment mechanism for securing the inner ring to the polymer body and sealingly securing the wooden head with the polymer body.

10. The composite barrel of claim 9, further comprising rivets securing said outer ring to said annular flange, said rivets having an internal bore, the inner ring comprising a series of apertures therethrough, each aperture positioned to correspond with the internal bore of each rivet when the inner ring is nested in the outer ring in a position for sealing the wooden head with the polymer body and the inner ring is secured to the outer ring by insertion of a fastener through the aperture into the internal bore of the rivet;

and an annular seal between the wooden head and the outer ring.

11. The composite barrel of claim 9, further comprising rivets securing said outer ring to said annular flange, said rivets having an internal bore, the inner ring comprising a series of slanted slots therethrough, each slanted slot positioned to correspond with the internal bore of each rivet when the inner ring is nested in the outer ring, the inner ring being secured to the outer ring by insertion of a fastener through the aperture into the internal bore of the rivet, the slanted slots angled such that rotation of the inner ring relative to the outer ring compresses the wooden head against the polymer body and seals the wooden head to the polymer body;

and an annular seal between the wooden head and the outer ring.

12. The composite wine barrel of claim 9, wherein the inner ring comprises a lower depending interior annular lip for contacting the wooden head;

the outer ring comprises a depending interior annular lip for seating the wooden head; and

the flange comprises an interior annular lip for seating the outer ring.

13. The composite wine barrel of claim 11, wherein the slanted slots comprise a serrated portion for gripping the fastener.

14. The composite barrel of claim 1, wherein the polymer body further comprises a further open end and the composite barrel further comprising a further wooden head attachable to the further open end of the polymer body.

15. The composite barrel of claim 1, further comprising a stainless steel insert for at least partially lining the polymer body.

16. A wooden head for use with a composite barrel for storing a liquid, the wooden head comprising:

an interior surface contactable with the liquid and an exterior surface; and

a plurality of channels formed on the interior surface to increase surface area for contact with the liquid.

17. The wooden head of claim 16, wherein the channels comprise cross-hatch channels.

18. The wooden head of claim 16, wherein the channels comprise linear T-channels.

19. The wooden head of claim 16, wherein the channels comprise linear U-channels.

20. The wooden head of claim 16, wherein the wooden head includes wooden planks.
