Wine bottles with corkscrews embedded
Connect the cork to a cup with a thread (male screw), and modify the bottle neck outer surface to form another thread (female screw) for the cup to move along the outer surface of the bottleneck | |
In other words,
1. Modify the outside shape of a wine bottle neck to form a male screw.
2. Make a cup with a plastic female screw to ride on it.
3. Connect the top of the cup with the cork, i.e., by a rope to connect the top of the cup with the bottom of the cork, or other means.
For example,
to presever the tradition of having corcscrew screwed into the cork, one could connect the top of the cup with the actual cork by driving a screw through both the cup and the cork during the manufacturing process.

Why didn't I think of that? But then again, this is why they invented wine bottles with screw tops also. |
|
| |
I think the design could be simplified. Imagine a 2-inch
cylinder, closed at one end. Now imagine a corkscrew
thread fixed to the inside of the closed end, so that it is
coaxial with the cylinder and protrudes from the open end
by maybe half and inch. |
|
| |
At the factory, the tip of the corkscrew is screwed into the
cork (to hold it in place), at which point the open end of
the cylinder screws down against the glass "collar" just
below the top of the neck. (The bottle itself is
completely normal.) |
|
| |
Now, if the purchaser continues to twist the cylinder, the
cylinder can't move down any more, so the cork must
come up. In the end, the cork winds up inside the
cylinder with the screw running through it. Simples. |
|
| |
But aesthetically unacceptable. [-] |
|
| |
Also, it is really high time that wine bottles were
standardized into maybe half a dozen shapes and colours,
and reused like milk bottles instead of being wastefully
crushed and recycled. Fancy screwey shapes would be a pain
in the neck. |
|
| |
Nothing to say that such a device could not be adhered to the top of a very conventional bottle using a heat release adhesive. None of the current screw out "corks" utilize an "organic" (read: cork bark based) closure, all use some form of poly, although some now use the new breathable foam poly that is supposed to allow some ingress of O2. The basic concept is very well worked out. |

Good luck with that [Maxwell]. How is the dairy doing? |
|
| |
In the UK, the dairy industry is doing fine, and has been
recycling its bottles for many decades, thanks. |
|
| |
Are people consuming THAT much wine to make recycling the bottles economical? |
|
| |
what is the minimum volume required to recycle? 1 would be my guess. Recycling wine bottles requires that the product have either an immediate turn over (no aging on the part of the consumer) or an acceptance that the label on the bottle be replaceable. Dispensing wine into unlabeled unmeasured containers for the purpose of off site consumption is currently illegal in the US. Beer may be sold that way, but not as it currently stands, wine. |
|
| |
The problem with reusing wine bottles is that all the wine is made and bottled in Spain, France, Italy, New Zealand, Australia, etc., and then drunk in the UK, so you have to transport the 'empties' a long way and the collection and transfer of the bottles back to the vineyard would involve many organisations. Reusing milk bottles (and yes, we still get milk deliverd to our doors in glass bottles) works because the bottles are collected from the doorstep by the milk delivery company who will transport them a short distance before reusing them themseleves. |

Maybe you just need to move closer to a wine region, [hippo].

Here in the South-West of Australia, especially in a glut year like this one, a lot of wine is sold off cheap in 'cleanskin' bottles, which would be especially easy to recycle. Pity no-one actually does (I mean, not directly, in the way envisaged here) ... |

Depends on the level of civilisation. Europeans will tend to
drink a bottle or so per houselhold per day. |
|
| |
[hippo] That is a very good point of which I hadn't thought.
But transfer betweenn European countries by sea/land might
not be prohibitive. |
|
| |
When I lived in France, you took your empties back to the supermarket, and put them into a machine that printed a voucher for the deposit refund on the bottles you had returned, so yes, I guess it was economical to recycle.
OTOH, they didn't sell anything but French wine, so I suppose the glass didn't have far to go. |
|
| |
Yes, although it may still be rendered uneconomic by the
need to make it profitable for more than one company and
to run a collection operation. Milk bottles are collected by
the same company that delivers milk and then reused by
that company. Wine bottles would have to be collected
from central locations where wine-drinkers deposit them -
supermarkets, for example - by a company which would
distribute them to the end-user, vineyards. This company
would have to
make a profit somehow and I'm not sure the cost of a new
glass bottle is high enough to be able to make a profit out
of collecting bottles and selling them back to
vineyards.
[pertinax] The south of England *is* a
wine region, just not a high-volume wine region. |

Or the UK could send them to Northern Ireland, where they could be filled with petrol. |

I am so glad that I just finished a small sip of wine before reading that. |

By that logic, [MB], the zenith of civilization is a shoddily dressed and smelly old man passed out by the dumpster behind the circle k. |
|

I did not specify a linear relationship. |
|
| |
We consider that a small pyrotechnic device would be infinitely preferable to all that fiddling round with corkscrews. |
