Is the reading 缶【かん】の縁【えん】 correct?

缶【かん】の縁【えん】でけがをしないように気【き】を付【つ】けてください

_Be careful not to injure yourself on the rim of the can._

<https://www.bosai-nippon.com/article/4242?paged=2>

I also found

縁【ふち】

and

縁【へり】

I found a number of examples here, but not an exact fit for the example
sentence of "the rim of a can":

Is the reading 缶【かん】の縁【えん】correct?
No, for the meaning of 'edge', it can never be えん.

I think 缶の縁{ふち} is more common, but 縁{へり} is acceptable too.

[This thesaurus entry](https://dictionary.goo.ne.jp/thsrs/15469/meaning/m0u/)
says

> ３「縁」は、平面状のもの、あるいは立体の外周部分をいう。
>
> ４「へり」は、平面状のものの外周部分をいう。「縁」とも書く。

As listed there, 目の縁{ふち} is more common than 目の縁{へり}. And 机の縁{へり} is more
common than 机の縁{ふち}. My impression is 縁{ふち} is more about a point along the
edge while 縁{へり} is the edge itself. (Cf. 崖の縁{ふち}に立つ vs 畳の縁{へり}を歩いてはいけない.) But
it is largely a matter of collocation.
