The patch kits with glue, here, come in convenient plastic boxes. They can be recycled.

Yeah - but my glueless box it about 1 inch square!
additional data
a few days ago I got my bike out to go for a ride
back tyre was dead flat
b****r
investigation revealed that the glueless patch I had put on had rucked up around the seam on the tyre and the hole had started to leak out through the fold
been ok for weeks but it must have been gradually been becoming less and less secure
now fixed using old fashioned ones with good old rubber solution - lots of it!!!!
and a lot of swearing at the tyre sealent that is supposed to prevent this - and lobbing some dosh at the LBS to get some better stuff rather than the off road tyre sealent I got off the internet
BTW - I assumed off road meant mountain bikes and such
turns out it meant JCBs and big trucks - so the amount to use on the instructions was not exactly relevant to the tyres I wanted it for!!!!
