We need a design for the top of a bottle (nipple/ring) made for our wide-mouth fundraising bottles. The two most important things are that the ring/nipple has a coin slot (minimum of 3cm x 5 mm) and the ring/nipple is a single piece (not two that come apart). Also, the end result needs to LOOK like a bottle top but does not need to function as one. There will be NO cover, just a ring and nipple.
We will be using a process that molds different types of plastic together at once which makes them all one peice (see NewProcess1 & NewProcess2 file). The ring/nipple will have to fit on an existing bottle (see "Bottle Sizing Details" for sizing) BUT we just need the size of the ring to fit on the bottle. It does not matter if the end design is taller or shorter - just that it screws onto the bottle. Also, the company we are using has engineers who will take care of the threads and the like - we just need to make sure the ring is the right size. YOU DO NOT NEED TO DESIGN THE BOTTLE - JUST THE NIPPLE/RING COMBINATION.
The challenge will likely be in incorporating the coin slot. Please be careful not to be too thin on plastic surrounding the slot which may cause it to break.
I am very involved in these contests and will constantly be rating and giving feedback. If you have questions, please ask and I will answer for all. The final decision will likely be made by our customers.
Background: Our customers want a wider bottle (wider opening, wider base, more capacity). They also don't want many pieces that just get lost. This bottle already existed but we want to redesign the ring/nipple to fit the needs of our customers.
