This is my first submission for the Terracycle bottle cap contest. My idea originally was for bees wax. I am a woodworker as one of my hobbies and occasionally will use bees wax to lubricate screws before screwing them into the wood. This helps more than one might think. With this in mind my thought was the bees wax could be packaged in the caps.This amount of wax for this purpose would be about right for most woodworkers and would be less expensive in this size so less waste would occur. Also if you lost this amount of wax you would not be out so much money. I, in thinking further about this thought why should it be limited to just this product. A company such as Burts bees who among many products sells a lip ointment in a metal two part container or the company that makes Carmex which is in a small jar. A “refill” could be sold for a little bit less expensive in the bottle cap and the contents be put into the original container to carry with you. Then this bottle cap turned in with others people would be collecting to reuse for this purpose.
Further why not other products packaged in the caps? Products such as foot powder, tooth paste, one days worth of vitamins,salt and pepper, and I am sure many more things could be applied to this. This small quantity could be considered a travel size or one use amount.
I really think this could be a viable use for these bottle caps. The one way I could see to enclose the caps is with a foil “lid” if you will or foil enclosure. Similar to what you see on a leading brand of Yogurt. This would be best done with the automated machinery that would glue the foil over the top to seal it properly. I could also see the possibility of two caps with a tape type seal around them to hold them together for twice the amount of space or quantity. Maybe even come up with a way to have a “cap” for the cap as it were. I am not sure how that would be done but that would be excellent as well.
I used regular parafin wax to illustrate this and made my own aluminum foil enclosure.
