Plastic and food waste are one in the same. Spoiled food stores in plastic bags ends up in the trash together.

Frozen vacuum sealed food on average makes food last 2-3 years.

Plastic bags take over 1000 years to degrade, yet still leave behind harmful microplastics.

Current Products

Manual Vacuum Pumps

+ simple
+ no electronic waste
+ uses reusable containers
- not repairable
- cheaply built

Hand-held Vacuum Sealers

+ simple
+ uses reusable containers
- unreliable
- e-waste at end of life
- not repairable

Countertop Vacuum Sealers

+ durable
- complicated
- e-waste at end of life
- uses disposable bags
- not repairable

Market Oppurtunity

What if there was a solution that reduces waste while also providing a satisfying and inuitive user experience?

Venturi is for consumers who want products that are time efficient, sustainably constructed, durable and reliable.
"I rarely use my counter-top vacuum sealer because I end up wasting multiple bags before I get a good seel on my food."
-Nicole G.

Allen: 36 years old

Unhappy with current sealing options because of the plastic waste and complicated operation.

Needs to vacuum food at small scale.

Wants a long lasting and simple solution.

Appreciates satisfying analog mechanisms.

Proof of Concept

Goal

Seal a vacuum bag using Bernoulli's Principle and the Venturi effect.

Bernoulli's Principle

"An increase in the speed of a fluid or gas occurs simultaneously with a decrease in static pressure."

Venturi Effect

"A reduction in pressure when a fluid or gas moves through a constricted section of a pipe."

Material Considerations

Thermorplastic Polyurethane

+ durable
+ smooth
+ recyclable

Thermosplastic Elastomer

+ inexpensive
+ grippy
+ recyclable

Aluminum

+ durable
+ lightweight
+ recyclable
