D:
And then I think you should draw another line from the body for the
label.
I:
Right “label”. The aluminium is ironed out until it’s
so thin that it produces
Q27
what does it say?
D:
“A reflective surface suitable for decoration.”
I:
That’s right apparently it helps advertisers, too.
D:
Yes, because it’s so attractively decorated.
I:
Good … and then there’s the
base.
D:
Yes, it says the bottom of the can is shaped like a dome so that it can resist
Q28
the internal pressure.
I:
That’s interesting. I didn’t know that.
D:
Nor did I. OK, so going up to the
lid … there are
several things we can label
here. There’s the rim around the edge which seals the can.
I:
Got that. And there’s a funny word for the seal isn’t there?
D:
Yes, it’s a flange
Q29
I:
What does it say about it?
D:
Well, the can’s filled with coke or whatever and after that the top of the can
is trimmed and then bent over to secure the lid.
I:
That’s right, it looks like a seam. We could even do a blow-up of it like this
F-L-A-N-G-E ...
D:
Yes, that would be clearer.
I think we should label the lid itself and say that
it constitutes twenty five percent of the total weight.
Q30
I:
Twenty-five percent … so it’s stronger than the body of the can.
D:
So to save money, manufacturers make it smaller than the rest of the can!
I:
Didn’t know that either ... so how do we open a can of coke?
D:
Mmm … first of all there’s the
tab which we pull up to open the can and
that’s
held in place by a rivet.
I:
Mmm … I think that’s too small for us to include.
D:
I agree, but we can talk about it in the presentation. We
can show the
opening though
Q31
I:
That’s the bit of the can that drops down into the drink when we pull the
tab.
D:
Yeah, hopefully. Sometimes the tab just breaks off.
I:
I know.
D:
Anyway the opening is scored so that it pushes in easily but doesn’t detach
itself.
I:
OK, we can show that by drawing a shadow of it inside the can, like this I’ll
label it
scored opening. Great … well, I think we’ve got
the basis of a really
interesting presentation. Let’s go and photocopy the article.
D:
Fine. I’ll take it home and study it some more.
