I love all of the clever projects, usually communicated in images only, that float around Facebook and G+. This one was spotted on the Whynomics Facebook page. Sadly, most of them usually have no attribution or additional information. This pantomimed project obviously shows how to make a neat little sandwich caddy by simply cutting, scoring, and folding a gallon plastic milk jug. A Velcro dot is used as the fastener.



You can see the original post and more complete directions at http://familyfun.go.com/crafts/reusable-lunch-containers-785113/ including a nifty idea to use juice cartons as well.
Thanks for that link, Professor! How are you doing?
Nothing sticks to polyethylene for very long. The stick-on Velcro will grab its mate harder than its sticky back can hang onto the jug unless you stitch it to the plastic. Better to crimp in a snap or cut a tab-and-slot closure to make this work for more than one sandwich (or photo shoot).
Good idea! Another (lower tech) possibility would be to make a slot and tab type fastener. It might get bent and not work if you aren’t careful, but it will probably handle getting washed better and doesn’t require any additional tools.
I used Duck Tape with a courtesy tab to keep mine shut. Never underestimate the power of Duck Tape!
A nifty idea, but I’d be a little concerned about keeping this sanitary. I’m not sure this sort of plastic will hold up well in a dishwasher, but I think you would want to give it a good hot-water wash after use to keep the microbes under control.
I made one of these caddy’s & packaged up some homemade cookies in them as a gift. I used E6000 to attach the velcro dot, but I like William’s idea about crimping on a snap!

Hate to be the science nerd in the room, but plastic is actually quite porous on a microscopic level. The nooks and crannies do an excellent job of holding onto bits of whatever was in contact with it, which means this repurposing of a milk container is providing a growing medium for whatever bacteria it accumulates. This is why it’s generally a bad idea to re-use plastic bags, even if you’ve rinsed them out.
I don’t know about your area, but in mine, those jugs have a $2 deposit. $2 can buy a much better sandwich container.
where is it that they have a deposit like that? very impressive if true- but what is the point really?
Cool.
I think a rubber band would hold it closed just fine. I also think there’s nothing wrong with a few ambient microbes, unless you are using this container to hold an organ for transplantation.
thankyou!
Haha…I love how you phrase that. Unless we don’t have a functioning immune system I guess we should be able to deal with a few microbes. Organ transplant certainly puts it on awhile different plane…
