The push-off / push-on cap

The all-the-time (inseparable) attached bottle cap already exist, and the problems here are (depending on their type):  are expensive (special because there are two pieces, produced separately and then combined together), not so easy to use, unsafe (for sparkling sodas or on handling could pop-up), they could produce another small protective cap or tear-off waste and – in some cases – the bottles cannot be refilled ( reused).

There are too many types of bottles and contents, so it will not be an universal solution, but maybe ( and hopefully ) we’ll have more small ones.

 Something like a collar on the bottle neck with an attachment to the cap for sure is better then the existing free disposal cap model, as long as the cap move free on the attachment ( like a small bump on the cap with a small lasso, or stretched circle, on the collar’s attachment). It already exist, special in the multi-use bottles, but the screw-type cap combined with the collar is not quite functionally.

One of the solutions could be the push-on / push-off cap. The bottle (plastic or glass) have to have a rim on top (fig. 1) (the glass bottles already have that rim), and another rim a few millimeters down from the top (like on the plastic ones). On the top rim the tight cap could be stretched, passing after the rim, by pressing in the middle or all around ( depending on the diameter)(fig.2). The cap have an attachment with the collar (collar on the bottle neck , passed down of the bottom rim), and is only one piece of seal, non-disposal, opposite with this attachment and easy to tear it (same width like the attachment but shorter, for example, but for the handling is better the attachment to be thinner, as thin as the collar). The broken seal will serve like handle for taking out the cap (the push-off movement). Is not exactly necessary to have an (special) elastic material for the cap, is enough a thinner material on top with a thicker collar (rim) all around.(fig.3)

For certain types of bottles, or bottle mouth diameters, or for certain drinks could be  two seals, on opposites sides of the cap, to keep it safe.

That kind of bottle caps are much easier to handle, even with only one hand, so that could mean that they could be welcomed by the customers!

Another (very) good thing, the bottle mouth diameter could be bigger than the actually standards, making the refilling much easier ( that means the reusing will be more probably!).

Another good thing is the plastic economy, for (almost) the same kind of bottle we have (calculated) up to 20 % less plastic! (or, for the same amount of plastic, an diameter increase of up to 15%!). Great!

In that way the plastic cap waste problem will be (partially) solved, the cap will stay together with the bottle!

ADD could be used for the glass bottles, too!

Idea Title

Push-off / push-on cap

Company / Organization Name

I'm on my own

Where are you / your team located?

Canada, Quebec, Montreal

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

No more loosen plastic bottle caps, with no use, or no profit recycling. The inseparable and one-hand open/close caps could be a solution, based on plastic economy production, easy handling, bottle refilling facilitated, which will conduct at bottle reusing.

Which use cases does your Idea apply to?

Case 2 - Trevor & Benjamin

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

This is a worldwide use, for all the kinds of bottled liquids: water, sodas, juices, cooking oil, sauces, spices etc.

How do you envision scaling up your Idea?

I'm seeing first the introduction on a (not so big) bottled water company, or juices. After the testing period (and, eventually, models) I will pass to sparkling water and sodas. Here it could be a stronger, different type, because of the bottle pressure. Meantime, I will test a bigger bottle (mouth) opening, to facilitate the refill, and to conduct to bottle reusing. New bottle designs come (almost) monthly, that means it could be not so hard to find somebody interested in the greener one

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.

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

I'm looking to somebody interested in new greener products. Alone is hard to advance, and to be seen and known it could take long time. So, why to don't work together, for the everybody benefit?

Please describe from where your Idea emerged

I've seen, long time ago (and actually still exist, today) the long type screw plastic caps, after that it comes the shorter ones, and after that - to make them even shorter - means no more screwing possibilities (too short!), so it comes the push-off/push-on caps!

Tell us about your work experience

I'm Telecommunication Engineer. I worked in: telecomm. engineer (8 yrs), owner of a wholesale business and restaurant (8+5 yrs), telecommunication technician (10 years). Innovator and novel writer

Please describe your legal and organizational structure

I'm on my own for the innovations and writings, and for my job ( telecommunication technician) I'm the owner of an Incorporated Company

Please describe, in detail, your business model and how you intend to test and iterate this model.

The right way to propose a new model is the economical specs (here is 20% less plastic), the simplicity (easy way versus complicated, and here the one hand handling can have a major impact), and the tests (here are two kinds of tests, self-ones and made by a separate, independent company). Must have a minimum 100 bottles+caps for tests (temperature, pressure, refilling, shocks, bacteria, different liquids content, puncture, UV, time resistance, usage number, etc). These tests are critical

Please explain how your innovation will work within, potentially improve, and provide benefit to the plastics system.

It will be no more loosen caps, so at least this problem will be solved. The less plastic and the ergonomics one hand handling could be a good point, too. Still are two kinds of plastic, who must be separated in the recycling plant, so no difference then actually facts (think about the actual collar from the PET, permanently attached to the bottle neck). The multiple use capability could be a good point, too (different bottles and contents).Very small bacteria chances (no empty or loosen spaces)

Please describe, in depth, how your solution will reduce the overall environmental footprint of packaging.

To replace an (working) industry is very hard, the best way is to make the new one (on a small scale) and to prove (in time) that's working. After that step will be implemented on a larger industry. If the new created industry is ecological, greener, much better and more chances to be adopted. This small bottle cap design brings two main things: plastic economy and better environmental footprint, being attached to the bottle. It solve the loosen cap problem, at least

Please outline how your design, material, and delivery choices will influence price, and how you intend to address the price increase that may result from this solution.

The design will decrease the price, that's for sure (calculated 20% less plastic). The same design facilitate the bottle refill, that could contribute to bottle re-use. Multiple kind of usage and contents it's an asset, too. Same for the not-so-different design than the actual, and the simplicity of it. Common material (plastic) will contribute for the success (the new materials usually are expensive, not in time, in different conditions tested, and the unknown brings the fear)

Please explain how your solution will impact user behavior, and what design considerations you've included to ensure easy and intuitive interactions with your Idea. 

The idea to change an existing (working and tested ) model first must be the economical impact together with simplicity and ergonomics. In this case both the bottle and the cap must be changed, and here are the numbers:1. 20% less plastic (1800 mm2/2300 mm2);2. one-hand handling;3. permanently attached cap to the bottle;4. easy bottle refill accessibility;5. low chances of bacterial development;6.various use, like liquid content or bottle types The first two points are the best for a change

Please describe how you intend to use the prize funding, if selected as a Top Idea. Be specific.

Ordering the prototype, then the mold and the bottles+caps.Make my own tests.Assuming the tests are OK, pass to an independent company tests.Finding a new, small (eventually) company (bottled water, juice...) to present the product.Observe the flow
