Flavorbooks would be available in different sizes, depending on the how much they need to carry and where they need to go, and were inspired by my trusty Moleskine type drawing pad.

Small would be suitable for cream and coffee, and even taking juice on the road or lunchbox.

Pages are made from roll to roll plastic, with clever inline checkvalves molded into the plastic to help keep air and bacteria out.  

The spout can be heat sealled at bottling plant, split open to use by consumer, used as a straw, then to close,  folded over with a  rubber band or binder clip to hold it in place.

It needs no separate lid, cap, straws made out of a separate material. It's easy to recycle, or remake.  Flat pack is easy to mail back along with spent ecopackets.

Pages can be stacked like in a book for additional volume and made only using inexpensive roll to roll simple film, that costs less to ship around than empty hollow cans and bottles.

It operates a bit like a bellows in that squeezing helps press out the contents almost completely, 

This along with the checkvalve doesn't leak if tipped over, but if squeezed will pour out in a controlled fashion, and it doesn't need caps or straws, allowing it to be operated with one hand at all steps.


Below a closer look at the 'pinch' checkvalve (hard to see the valve). 

With the checkvalve, there isn't a need to use a twist or flip on cap to maintain freshness reducing steps required for operation.

This Airless approach throughout the operation, greatly extends the sweetness and shelflife of coffee, milk, cream, wine, and juice as in normal bottles it's the constant "breathing" from opening and closing bottles, that lets in airborne bacteria, mold, and yeasts as well as oxygen that cause typical spoiling.

Tips can be coated with teflon or other hydrophobic material to be drip free, and antibiotics for sterility (e.g. silver) 


could be made with any material (hardboard, cardboard, plastic, wood, metal, bamboo) to match the kitchen style and be easily washable. It helps it like a book stand on it's own.

Shown below in autoclavable sterilizable plastic, in liter sizes perfect for milk and yet still one hand use.


One hand use is important many segments of the population have limited hand use, like in RSI, Arthritis, Elderly.  It's only after you lose one hand you realize how hard normal life becomes, opening jars, making coffee, even pop top milk bottle tops can be annoying.

The hard cover like a book on it's end can stand on it's own everywhere, easily grabbed and put back.

In our model one hand use is simple as open the refridgerator door, hold open with body reach in with one hand to get bottle, tilt over cup, then gently press to trigger flow, precise control for even small glasses, tilt back up to stop flow, tap once to shake off the lingering drops if any, optionally rinse, then put back in fridge. No caps, screw tops, no messes. No bulky bottles filling up the recycling bin, less taking out the trash= higher quality of life.

Rigid Hardcover book, helps keep the formless bag upright into the refrigerator door, and many like an encylopedia, can be set compactly side by side (juice, water, tea, coffee) in higher space utilization than random bottles you get from the store (like the maple syrup shown). 


For portable keychain pump dispensors could be integrated with a "dock" like function (shown in drawing) for multichannel refills (e.g a page for coffee, one for cream, one for sweetener) dispensed and mixed precisely together when served (e.g. precisely sweetened coffee and cream to go), via microfluidic like flow controls.

Could be used for just about anything you'd typically find in the fridge, almond milk, daily milk, cream, juice, wine, purified water.

Most of which could survive in a mailbox or outside a door for a day with a reuseable chill pack so could be mailed.

This model is already partly done in delivery services like milk and eggs in los angeles.

Also place your spent refill bags/pages into a flat pack mailer with the spent chill pack with your spent ecopackets.  Which might be like this other entry


In a future service of full service of commodities "pay as you go" and an intelligent flavor book that knows how empty it is, a delivery driver gets notified of what's out, picks up the spent, replaces with fresh. Spent pages are cleaned and reused or remade as appropriate eliminating landfill waste.

Idea Title

FlavorBook, a new approach to mailable fresh commodities that fit in your refridgerator door.

Company / Organization Name

Cloud9 Brewing Systems.

Where are you / your team located?

Los Angeles CA, 90046

How does this Idea redesign unrecyclable small format plastic items that often end up as waste?

This roll to roll approach has reduced plastic use than bottles and cans, needing dedicated can or bottling plants, by using a molded in clever check valve, air and bacteria is kept out to greatly prolong the sweetness and shelf life of cream, juice, coffee, tea and wine all of which are oxygen sensitive. The Splosh like mailable insert/refill can be remailed back for refilling or recycling remaking. With an appropriate connector, can be used to refill smaller containers: sachet, pump

Which use cases does your Idea apply to?

A FlavorBook with an appropriate tip can be used as a 'mothership' to refill smaller containers, like refillable sachets (possibly silicone mini ziplock), keychain sprayers, hand/shampoo pumps. It doesn't need bottle caps, tear off, It costs significantly less than heavy or fragile glass or aluminum bottles being shipped around.

In what geographical context or area does your Idea plan to operate / solve?

Any with mail or milkmen like pickup and refill like service, potentially infield, recharge by the ml "pay as you go"

How do you envision scaling up your Idea?

The use in coffee, and cream and non-dairy ties into our cold brew espresso, drip and non-dairy milk, also in this challenge

At what stage of development is your Idea?

  • Research & Early Testing: You are exploring an idea, gathering inspiration and information needed to test it with real users.
  • Prototyping: You have conducted some small tests or experiments with prospective users and will continue developing idea through these tests.

Please describe how becoming a Top Idea and working with the Think Beyond Plastics Accelerator Program will help to accelerate your solution.

This concept has use in it's own business for anything from juice, water, wine, particularly for industry service (e.g. conference or soda dispensor like bags of syrupcoffee). It could use the benefit of an accelerator to flush it out.

Please describe from where your Idea emerged

As a single guy playing with cold brew coffee, and a bit of a zombie in the mornings from health issues, one too many times pouring cream that looked fine, into the latest cold brew coffee and taking a sip, finding it was bad, forcing me to spit out the coffee, and get cream and repeat the coffee experiment. (first world problems I know). In playing with smaller containers and checkvalves attached to spout bags, the cream stayed fresher and sweeter much longer than the glass bottle and cap.

I can’t believe this. A great testimony that i must share to all HERPES SIMPLEX VIRUS patient in the world i never believed that their could be any complete cure for Herpes or any cure for herpes,i saw people’s testimony on blog sites of how dr Ero prepare herbal medicine that cure and brought them back to life again. i had to try it too and you can,t believe that in just few weeks i started using it all my pains stop gradually and i had to leave without the pills the doctor gave to me. Right now i can tell you that few months now i have not had any pain,delay in treatment leads to death. Here is his email:( whatsapp him with +2348105150446 visit blog

it occured to me that like the coffee, a reasonable amount 90ml is machine envelope mailable, and ends back at the brewery for cleaning/remaking (incentived multiple ways) this completely sidesteps the distribution and recycling infrastructure integration headaches that challenge most other clever bottles and the like.

Put alternately this approach could reach everybody today with no friction, no opposition from big corps, and possibly easy integrations with them too.

We could start with coffee/espresso, then move to cream/non dairy milk (e.g. almond or our coconut oil based NomNomilk), then fresh juices.

Fast forwarding as blockchain backed hyperloop/smartcar/drone/segway delivery replaces the USPS/Fedex/UPS physical delivery network, it only gets better with time.

thanks mahindu! i appreciate the encouraging remarks

if one gets awarded, they all can become a reality in time, as i feel they all are important, elegantly simple so hard to mess up, affordable for all, and then when *we can all win* the best award, better lives in a better world :)
