Additional goals on their way!
 

 4 months ago we launched our first stretchy lid on Kickstarter called the EnviroShell. After it unfortunately did not work out we went back to the drawing bored to design and develop something better, stronger, and different. We are back now on Kickstarter looking to succeed in our dream of successfully launching a fantastic product to the world!

 We want want to keep our consumer base small, so that we can focus on fulfilling and caring for our supporters, that's why we are only asking for $450 and launching for 14 days! So hurry up and back now before the campaign ends!

Not only is the Ultrashell extremely practical and cheaper than using plastic wrap, it's very environmentally friendly. If everyone in the United States were to eliminate plastic wrap we would keep over 8 million tons of plastic from entering the ocean each year! Let's all start making a difference today!

The story and process of the Ultrashell development.

Originally my brothers wife was telling me about how she recently bought these cool stretchy lids that she really liked, but she mentioned how they kept breaking, snapping, and over stretching. She was frustrated because she loved the idea of them and how easy they made her life but they just weren't cutting it in quality. 

I then decided to check them out for myself so I could understand what was happening and if there was anything to be done to make them last longer. I went ahead and ordered probably 30 different kinds of stretchy lids of the internet. When I got them I was actually surprised, she was right, they looked nice but after not that many stress tests they started to snap, crack, and over stretch until they weren't useful anymore. To me the idea was fantastic, but I couldn't find any that were reliable, so that's when I decided to try and re-invent and re-engineer the stretchy lid.

How we designed & made our lids 4 times stronger

Early Appearance And Scale Designing 

Rather than trying to redesign the stretchy lid appearance, we thought best to use common dimensions and focus on changing the strength instead.

The first thing we did was look at stretchy lids on the market. It was important to figure out why they snap easily and stretch over time. After lots of testing and research, we determined common stretchy lids don't last because they do not have proper structure, because they do not have structure, the lids naturally stretch and crack over time. Once we figured this out we knew we had to design a very solid structure in order to be successful. The only thing useful to us with other stretchy lids were the size, tabs, and appearance. We decided to keep that part and focus our energy on making them stronger and last way longer.

Early Structure Designing and Prototyping

For our first ever silicone cast we did not add tabs. This stage we are just focusing on testing the strength and the usability of our stretchy lid, convenience for us wasn't important quite yet.

Since we knew we had to create an internal structure to make our lids strong, we decided to continue to use silicone. If we created a silicone skeleton we could then cast a layer of silicone on top and a layer on the bottom, this would work best and the skeleton would hardly be visible. Our first skeleton concept was a complete failure. We thought making an ex shape with the tabs as part of the skeleton would be fool proof but it proved to be a mistake. When the lid expanded it pulled the entire skeleton and opposing tabs with it causing more stretching, stress, and ware to the lids. We needed to create a design that would be relatively stress free, move fluidly, and retract naturally.

The Design That Finally Worked!

Throughout the prototype phases, we also experimented with dying our silicone different colors, but in the end decided with light blue and basic clear.

After many iterations, concepts, and prototype failures, we finally landed on a design that seemed to work perfectly. That was our zigzag skeleton. The zigzag skeleton has four zigzag circles starting from the inside and moving out. None of the zigzag circles are connected so it allows the lid to be stretched in any direction perfectly and fluidly. The zigzag is very important because after the lid is stretched it naturally retracts the lid to its original shape and size. The skeleton ads the strength that we were looking for and the longevity we needed. 

Final Prototype Testing

The above video shows the team pulling the large 8.27 inch stretchy lid. It's important to exaggerate the conditions of the lid to be sure it can handle anything without snapping or cracking and retract to it's regular size without any expansion.

This video shows a basic product test (with our yellow zigzag skeleton lids) to see if it can hold an airtight seal without any leakage. The video also demonstrates the usefulness of the pull tabs. Even if you apply the lid crooked, you can easily pull it straight.

Risks and challenges

We have only ever done a small product launch before, so we can not promise that it will be completely smooth or error free on our part.

We are going to try to do our best to make things work properly and deliver on our promises, but we do hope that our supports can give us a little patience with our flaws and inexperience.

Long-lasting design

We've spent the last 4 months creating a design that is 4 times stronger than the original so we can better guarantee that our lids will last longer than competitors.

Reusability and recyclability

The ultrashell stretchy lid is dishwasher friendly, so you can clean and re use it as many times as you need. No more plastic wrap!
