Upon comparison, it was noted that the soda cap (following opening and removing), was the same diameter and nearly the same height as that portion of a deodorant package that the user turns to dispense the product. Further research indicates that the soda cap and deodorant package are both molded from the same material, and are nearly the same weight. This qualifies the soda cap as a possible fit to redirect to the deodorant package.
Further, the possibility of a take-back for the soda cap by the company was considered, but there is the round ring that seals the cap to the bottle -- the seal is broken upon opening and remains around the bottle. The questions that must be answered: Would it be cheaper and cause less environmental impact to recycle it? Could it be taken back and reused at less or the same expense?
Rightfully so, production costs and processes are proprietary and confidential, so a simple comparison was performed with the data that was received:
Parts Interchange Example:
Class: Packaging to packaging
Subclass: Food to non-food
First generation part: 2-Liter or 20 oz soda bottle cap
Second Generation use: Twist piece at base of non-roll-on deodorant package
Modification Necessary for exchange: Slight, if any
New Intellectual Property: Method for attaching screw rod to soda bottle cap
Parts Comparison, 1 Million Pieces:
Substance | Size/Shape Comparison | Weight | CO2 Emission | Percent of Useful Part | |
| Soda Cap | Polypropylene | Round, Diameter: 2.8 cm Height: 1.1 cm | 3.1 Grams | 5270 kg | 100% |
| Deodorant Twister | Polypropylene | Round, Diameter: 2.8 cm Height: .9 cm | 3.7 Grams (including screw rod) | 6290 kg | Approx. 90% |
In this example the part-yielding manufacturer would have no action to take whatsoever. The company accepting the part would then have to consider if organizing a redirect of the part to include in the production of the screw rod (which is attached to the twistable part) would benefit them in terms of environmental impact, as well as costs, both areas of which would have to be considered for:
- Getting the parts to the manufacturer -- a simple drop off bin for soda caps could be arranged at grocery stores or perhaps sporting events. Then there is the pick-up and transport -- the ailing U.S. Postal Service could benefit from regular pick-ups such as this. The indirect carbon emissions of the transport would have to be factored in as well.
- Attaching the screw rod to the soda cap, to then serve as the twistable, exposed portion of the deodorant package.
- Modification -- The difference in height is slight but may be prohibitive if not addressed. Either the portion of the deodorant package that accepts the screw rod would need to be stretched to compensate, or the soda cap manufacturer could slightly lower the height of the cap.
A third-party facilitator could easily be employed to confidentially coordinate with both parties, do the necessary analysis, and assist in implementing the change.
That is the commonality between deodorant and soda -- one part of the packaging. Who will try it first?
