Duo-Can has an opening at the top
and another one at the bottom, along
with
a separating division half way up the can.
This means that when you only want to
have a small glass of beer, or drink it
slowly you don't have to worry about the
rest of the can going flat.
You could always put a lid on it...

So simple, yet so useful.... [+] |
|
| |
would there be a drip problem? |
|
| |
Why not just buy those new haf-sized cans they're now selling in supermarkets? |
|
| |
[DrCurry] or glue two of them together ? |
|
| |
[erlehmann] exactly my thinking, gaffer tape, and two upended cans of RedStripe lashed together. Brilliant. Also, I can see this technique serving for lager drinking in the midst of jungle combat. |
|
| |
xenzag/erlehmann/zen_tom: um, no, because then once you've drunk one half, it drips on you when you drink the other. |
|
| |
How does it drip on you when the empty
half is tipped up and the full part points
downwards? |
|
| |
//you only want to have a small glass of beer// |
|
| |
In jungle combat, it's ok to drip a little lager. It confuses the flies. |
|
| |
xz: you drink first half. Put can down. Later, you come back, turn can over to open the other half and raise it to your lips. Bottom half of can drips on you. |
|
| |
In jungle combat, you simply machine-gun the finished can off the stack, fashioning the twisted remains into a vicious boobytrap. |
|
| |
DrC - one NEVER drinks from the can - far
too vulgar.... and think of all those rat's
urine spiced feet that have tip-toed over
the sealed rim before you put your lips to
it - euach ! |
|
| |
Perfect for a double date. [+] |
|
| |
Or a re-sealable / screw-top bottle. |
|
| |
This is why Grolsch is the superior product. Well, this, and many other reasons, too. |
|
| |
// Grolsch is the superior product // |
|
| |
Even though it tastes like carefully refrigerated cow piss ? Real ale, we say, reale ale is the thing ... refuse all substitutes.... all substitutes are refuse ... |
|
| |
er, I recognised all the drips first - I know all of the above ;) |
|
| |
//How does it drip on you when the empty half is tipped up and the full part points downwards?// no, the full part is at the top - kinda near your mouth. |
|
| |
We've had these in the UK for years. |
|
| |
Perhaps these could be sold with a plastic snap-on lid. Kinda like on a Pringles tater chip can (sorry for the Americanism. I is one.) You'd only need one lid. When one side is finished, snap the plastic lid over the used side, stick back in fridge and chill 'til ready for the other side of the drink. That would solve the drip problem. |
|
| |
// bottled and fed to beer drinkers // |
|
| |
We think you mean "lager drinkers". |
|
| |
Real Ale is a rich, complex, deeply satisfying beverage of up to 13.% alcohol content (although that's actually a barley wine, and should be drunk in pints only by the habituated or seriously foolhardy). Real Ale can taste of chocolate, or plum pudding, or treacle, and can produce residual flatulence of such volume and duration that it can be used as a feedstock for industrial processes, a fuel, or in some cases a low-lethality riot-control weapon. |
|
| |
tastes like raspberry to me. |
|
| |
The can is going to be hard to make--not impossible, just much more expensive than two regular cans full of beer. And you'll want to avoid putting it down while drinking the first half, or the second half's rim is going to taste like . . . like . . . what tastes worse than beer? |
|
| |
It wouldn't be hard to make. First, you
make two regular (but shorter) cans. The
bases need to snuggle nicely. Then you
just glue them base-to-base. |
|
| |
[sometimer]'s suggestion of a snap-on
plastic cover is good. |
|
| |
As always, [MaxB], your insight serves you well. I was thinking of a single drawn can body with a divider glued into the middle of the inside. Two short cans glued together wouldn't cost any more than two short cans not glued together. |
|
| |
Ahem, what about the cost of the glue? |
|
| |
// Two short cans glued together // |
|
| |
It will cost more in materials ...... the divider will be in effect dual-walled. |
|
| |
A typical 330ml can is 110mm high and 68mm in diameter. |
|
| |
That gives a total surface area of 23487 mm2 for the side walls and 3629 mm2 for the base, neglecting curvature. |
|
| |
Thus the base is 13.5% of the total area of the can (neglecting the top, wich is a separate component). |
|
| |
If the can is shorter, the proportion of the base relative to the overall size of the can increases, since the base is of constant diameter. |
|
| |
For a 500ml DuoCan, the sidewall area is 35586 mm2. The base area is still 3629 mm2, which is 9.25 % of the total material. If you have a dual partition, that will mean an extra 3629 mm2 of material, thus increasing the raw material cost of the can body by 9.25%. |
|
| |
Agreed [8thof7] what's required is the ability to purchase beercans by the yard.
Me: Shopkeep, 3 fathoms of your finest Red Stripe please. And be quick about it.
SK: Would you like that in feet, or yards sir?
Me: Yards you fool! Do I look like the sort of fly-by-night, flibbertijibbet who would purchase his drink by the foot? I have been trained in jungle combat!
SK: Very good sir.
Shopkeep shambles off into the back of the shop.
<sounds-of-heavy can-crimping machinery and liquids being pumped>
SK: Here you are sir, that'll be 5 shillings 7d please guv.
Me: There you go my man, good day. |
|
| |
Bottom half - Cheese, peanuts or shoe wax. |
|
| |
You must look pretty funny ..... by the way, what do you want in your DuoCan ? |
|
| |
Me: Shopkeep, 3 fathoms of your finest Red Stripe please. And be quick about it.
SK: Only what you see on the shelves, buddy ......... |
|
| |
//thus increasing the raw material cost of
the can body by 9.25%.// Yes, and in fact
the cost increase will be much more than
that - the base of the can is thicker than
the walls. However, for a modest sales
premium, not an issue. |
|
| |
// the base of the can is thicker than the walls // |
|
| |
Yes, we noted that in the exemplar, but it would have added excessive complexity to the math. |
|
| |
In fact, it's worse, because since the base of most drawn aluminimum cans is concave over a greater part of their profile, the available area for adhesive (or possibly rotary seam welding) is restricted. Therefore careful surface preparation would be needed. It amy be possible to weld two cans base-to-base using a TIG welder or an electron beam welder (in a vacuum chamber) but it will not be an easy task with such thin material.
The alternative we considered was 3 or 4-point interior spot welding. If this is done before the can is filled and the lid fixed then it should be fairly secure, but steel cans would be better due to the need for agressive surface preparation with aluminium, and subsequent cleandown. The legending would have to go on after the welding, as the heat might damage the finish, and to ensure the legending is aligned on both sections of the container. |
|
| |
//In fact, it's worse, because since the
base of most drawn aluminimum cans is
concave// |
|
| |
Ah but. They needn't both be concave.
You can't have a flat base, because it
will bulge under pressure (if one halfcan
is opened and the other is still sealed).
However, either a concave *or* a convex
base would be fine. So, make the
halfcans in pairs: one with concave
base, one with a convex base. They will
then mate together seduciously, and
will offer a large contact surface for
gluage. |

//They will then mate together seduciously, and will offer a large contact surface for gluage.// |

i always appreciate the opportunity to learn new words as english is not my primary language. |
|
| |
i'm thinking it should probably be seductively or salaciously, that, or you are the 21 year old female named Sloan from IL who claims to have invented the word "seduciously". [from google - only 1 hit comes up for the word and it's on myspace, how very hip]. |
|
| |
Sorry - I meant salacively, obviently. |
|
| |
// one with concave base, one with a convex base // |
|
| |
All very well, but this will give the two containers different volumes (we also considered this), meaning that the one with the convex base needs to be slightly shorter over all than the other, resulting in an unaesthetic lack of symmetry. |
|
| |
...or the ability to decide whether you are
slightly more or slightly less thirsty at that
precise instant. |
|
| |
The exterior volume of the concave base of a 330ml can is, by practical measurement, approximately 20 ml. On a 500 ml Duo-Can, that would make one side about 8% bigger than the other. |
|
| |
My wife is about 16% more thirsty than I am, right now. Give her two cans, I'll have her bottoms. |
|
| |
We hope you're aware that that's still a criminal offence in many less liberal jurisdictions, including many states of the U.S.A. ? |
|
| |
I imagine that penetrative sex with an aluminium can would pose various lacerationary difficulties that would deter all but the the bravest (or foolhardy) of gentlemen. |
|
| |
unpeakable *should* be a word. |

God. what is the best way to show a picture of a 4D object? i only can draw three dimensional coordinates. -david lowenstein |
|
| |
well, it's possible to draw a 4D object! surprise! just make the fourth axis to be the fourth corner of a tetrahedron! all line segments must go away from each other, or this graph will not work. added to the fact, that space and time are both four dimensional, 4D objects can be seen! amazing, is it? well, one cannot have 4D eyes, only we gods can have them, but they can use 4D cameras. just use transmitters! -God |
|
| |
awesome! -david lowenstein |
|
| |
yeah. that's the awesome part. -God |
|
| |
another question. is a duocylinder, stacked tori, or linked tori? -david lowenstein |
|
| |
actually it is linked tori! surprise! everyone can see the fourth dimension! -God |
|
| |
Lord Yahweh. Can there be a duocylinder equivalent of a juice can containing two different juices? i want to drink out of a duocylinder! -david lowenstein |
|
| |
well, since we Gods can build anything, of course, since we are Gods, we will help the cosmos to make duocylinders filled with two beverages. -Lord Yahweh, thank you, dave, for saying my name again. |
|
| |
you are very welcome, lord yahweh! thank you, Lord yahweh! -david lowenstein |
|
| |
you are very welcome, david lowenstein! -Lord Yahweh |
|

we at dole juice and duo juice are hyper-confused. you are asking us to make a four dimensional juice can that can never fit into our three dimensional space and put two juices into it? we'll love to make a duocan, but may God help us, because only with God's help, we can make a duocan. well, we really love the idea! it will become a permanent symbol of God's ingenuity in a popular way to drink juice. well, we hope we can make all duocans holy, because it is a higher form of a regular three dimensional can. and the can will be magical too, since it exists in a higher dimension than ours! hey! the duocan is also futuristic, because in the future, there are better ways of doing things! thanks, dave! we will make sure the better nation columbia appears before we, with the help of God, attempt to build the world's first duocan for drinking juice. thanks, dave, for the idea! we love it! -us at dole and duo juice |
|
| |
you are all very welcome! -david lowenstein |
|
| |
well, a duocan is basically shaped like two doughnuts linked together with each one having a top. |
|

// It may be possible to weld two cans base-to-base using

|
| |
It is. I could easily TIG two beer cans together. Cleaning
and surface prep is pretty simple, too. |
|
| |
// It amy be possible to weld two cans base-to-base using a
TIG welder […] but it will not be an easy task with such thin
material. // |
|
| |
I know someone who managed to do that, and then refill the
result with beer, with the drinking apertures still factory-
sealed. I don't remember exactly how she did it, but you're
right about it not being easy. |
