Designed to be filled on a brewery filling line, the wide mouth
closure is removed at the point of sale, which enables the A-Can
to be sold faster than any other beverage dispensing method used
at large public events covered by the Sale of Alcohol legislation.
The A-Can takes less than 3 seconds to open and serve and can
not be used as a missile.
Working on a consultancy basis, the brief was to
improve on the A-Can by removing the need for a
dedicated filling line and improving the seal of the
g p g
closure to the container.
This was achieved by providing a plastic cup with
a double closure – a standard closure for filling on
existing bottling lines and a removable larger
closure for drinking from.
The larger closure is installed in a packaging
g g g
factory prior to filling, enabling a more diverse
palette of technologies to be used in achieving a
A substantial patent portfolio was generated
during this development for the client.
Out of a personal requirement for a can of hot chocolate anywhere, anytime grew the brief for the Thermotic
Can: a self-heating beverage container capable of heating 210ml of beverage by 40˚C in 3 minutes, and
filled on existing canning lines, heat-treated and then “charged “ with heating components.
The development of the Thermotic Can involved putting together a multi-disciplined
team drawn from financiers, universities, the lime, plastics, metal packaging and foil
The launch vehicle, Thermotic Developments, raised £6m of venture capital to fund
development and pilot production.
Sold 6 million cans to Nestlé for regional test market in the UK with Nescafé, its
largest brand. This is believed to be the second most successful beverage launch in
Direct Steam Heating
Market traction generated a need to heat food and viscose beverages by
means of direct steam heating.
Direct steam heating uses steam produced in an exothermic reaction to
transfer heat directly to the food or beverage. The steam condenses into
the product and releases its heat.
Direct steam heating is:
• faster than a microwave
• delivers a better taste and texture, as good as freshly cooked food.
• is clean, hygienic and healthy.
It takes between 2 and 4 minutes to heat chilled food, soup or beverages
from 5˚C to 70˚C.
Development was carried out on a Mk2 pack, a handheld snack pack and
a beverage cup before work was stopped due to a change in marketplace
sensitivities, when concern for the environment displaced convenience as
the key driver. The lime / water chemistry of the Thermotic Can and
Steam To Go packs, although perfectly suited to disposal by thermal
energy recovery, is heavy and bulky.
A project to find a replacement chemistry for all self-heating requirements,
both civil and military, is underway with The Nano Heating Company.
I have worked on self-cooling packaging in parallel with self-heating. The quest for the
self cooling self heating.
self-cooling beer can continues but awaits a breakthrough in technology before
becoming commercially viable. One solution that is nearer market is the stay-cool
concept wherein the coolth already added to the pack by the retailer is maintained by
the use of heat sinks and thermal insulation. Proof of concept prototypes have
demonstrated this concept and have shown that it is possible to maintain coolth for
In 2006 the US Navy produced a requirement for an Individual Field Service Drinking Water Cooler.
The Chilly is a direct response to this requirement.
Drinking water passes through the succession of cooling elements and is cooled progressively as it flows
through the device. The Chilly combines light weight and ruggedness with full drinking water approval and UV
stability. It requires no external power source as the cooling is purely by evaporation. A small amount of water
is transferred via a wick to the outer covering from where it evaporates, cooling down the water in the unit. The
wicks and covering fabric contain silver as an antimicrobial and antifungal barrier.
Mistral Under Armour Body Cooling System
Another major problem facing troops operating in hot environments is heat stress.
The Mistral liner is integrated into existing body armour designs and uses the same fillers and plates, thereby
maintaining ballistic performance
Tightly controlled ambient air is directed through vents located along the length of the sternum and spine. The
sculpted inner face of the Mistral system directs dry air across the skin and allows saturated air to exhaust
around the arm openings. Three separate cooling circuits operate sequentially as the cooling zone changes
every 20 seconds. The Mistral system provides a unique continuously cool feeling due to the intermittent
stimulation of the body’s coolth receptors. It complements the body’s natural cooling system by assisting the
evaporation of sweat from the majority of the torso surface.
The plug-in fan unit is easy to disconnect for replacement or to connect to vehicle a/c systems making the
Mistral system ideal for AFV based troops. The total power of the a/c is fully utilised in crew cooling allowing
them to operate for longer in the intense heat of an armoured vehicle.
The Mistral system is available to manufacturers of body armour to license for use around the world, and has
generated interest from military and police forces on five continents.
