1) Field of the Invention
The present invention relates to an intelligent refrigeration unit designed to store and dispense beverages such as beer.
2) Description of Related Art
In modern times, the craft beers and microbreweries have become popular with consumers. With this movement the use of cans has rapidly increased. One study places the number of companies that are using cans to package their beverages at over 500. However, there is a movement to reduce the number of cans being produced and to reduce waste by supplying glass bottles that can be refilled from breweries. Commonly these glass bottles are called “growlers”.
It is believed that in the 1800s, fresh beer was carried from local bars and pub to homes in a metal pail. These pails were pressurized by CO2 and when the beverage sloshed in the pail, it created a “growling” sound as the liquid moved and CO2 escaped from the pail. In modern times, a growler is glass bottle that can include rubber lined caps, ceramic tops with a O-ring or seal, or other lid designed to prolong freshness. While a growler will keep beer fresh for one to two weeks unopened, once a growler is opened, the beer will only stay fresh for about 36 hours before it goes flat.
When the growler is initially filled, there is a disadvantage in that air can be in the head space of the grower. Headspace is a volume of about 5% of the volume of the glass bottle where gas is disposed. Other glass bottle includes fill lines to prevent filling the growler to the top of the opening. Air in the headspace causes the beer to oxidation making the beer undesirable. Counter-pressure filling the headspace with CO2 can reduce the chance of oxidation and has been shown to provide shelf lives of 4-6 weeks from unopened growlers. Some beers stored in 32-ounce swing-top growlers under cold, dark refrigeration have lived upward of 3-6 months without trace of oxidation making the present invention advantageous.
In response to the popularity of the craft beer, brewpubs, and microbreweries, growler filling stations have been opened such as the device shown in U.S. Pat. No. 9,073,741 which discloses, generally, a system for dispensing beverages, including, beer into containers, glasses, growlers, and the like. One such bottle is shown in United States Application Publication 20130032564 that discloses thermal metal containers principally for use in the purchase of beer from a brewery or pub off of a tap.
In the industry, there is a need to provide for a growler that can allow the storage of the beverage (e.g. beer) for a lengthy period of time much past the 24-36 hours currently possible. While the pressurized growler substantially lengthens the storage time, once the growler is taken home and opened the benefits of the pressurized system are lost. An attempt to lengthen the time that the beer stays fresh has been attempted through recharging caps such as United States Patent Application 2014/0262899, however, the cap needs to be used each time the growler is opened. Another attempt to preserve freshness is shown in U.S. Pat. No. 9,193,577.
However, a problem for which much attention should be spent is how to keep a growler's contents fresh, refrigerate the growler, dispense the contents, and allow for multiple growlers to be stored, preserved, refrigerated, and dispensed from a single unit.
Additionally, there is an inconvenience with growlers stored at home in that when leaving work or other location and returning home, the amount of a beverage in a growler is not known without physically being home. There for it would be advantageous to have a way to retrieve the volume and type of beverage in a growler from a remote location. It would also be advantageous to be able to collect, store and retrieve information related to the contents of a growler, the length of time between re-fills, the temperature of the beverage, the number of pours from a single growler and other such statistic information. Such information would also be advantageous to be aggregated for statistical analysis for vendors, user and the like.
Accordingly, it is an object of the present invention to provide for a storage and dispending unit that preserves the contents of a growler as well as keeps the content refrigerated.
It is another object of the present invention to provide a multi growler unit.
It is another object of the present invention to provide a data collection, storage and reporting unit to collect, store and report data related to the storage and dispensing of a beverage from a growler.

A temperature sensor 60, humidity sensor 62, and gas sensor 64 can be attached to the controller and disposed in the recess to record environmental conditions within the compartment that receives the beverage containers. The temperature of the recess can be controlled by refrigeration member actuator 66 which can control the refrigeration member. The control unit can received a pre-set temperature setting representing the desired temperature of the beverage container contents. The control unit can activate the refrigeration assembly when the temperature exceeds the pre-set temperature and deactivating the refrigeration assembly when the temperature falls below the pre-set temperature.
The control unit can also include an input allowing information, such as beverage container, growler, or fluid to be entered into the control unit and stored in writable memory 70. For example, the user can insert a growler then input the type of beverage in the growler, the type and/or size of growler, the location where the growler was filled, and other information concerning the growler and its contents. The control unit can determine when the beverage container plus the fluid is changing as fluid is dispensed from the beverage container. By recording the starting weight and the ending weight, the control unit can approximate the amount of fluid dispensed as well as the amount of fluid remaining in the beverage container. When the housing doors are opened, a door sensor 72 can record the number of open and close cycles as well as the time the door was left open. A flow meter 74 can be included in line with the supply line to measure the amount of beverage that is dispensed from the growler.
In one embodiment, the purge actuator 104 is connected to the control unit. When the purge actuator is actuated, the control unit receives information from the actuator and responds by opening a purge valve for a predetermined period of time to allow gas to flow into the removable cap attached to the purge assembly. By having the control unit open the valve for a predetermined period of time, the beverage container does not received excessive pressurized gas to displace the existing gas in the headspace and foam produce resulting from this process is reduced. Additionally, by metering the amount of pressurized gas that enters the beverage container, over-pressurizing is avoided, and therefore pressurized gas is conserved and unnecessary foam production is avoided.
In one embodiment, the control unit can include a transceiver 68 allowing communications with a remote server 76, portable compute device 78 (e.g. smart phone, iPhone, and the like) or other controllers. The controller can transmit and receive information from the remote computer or smart phone. For example, a user can access the smartphone, or more specifically an app on the smart phone, and review information such as the beer that is current in the growler, the environmental conditions, the amount of beer left in the growler and the time the beer has been stored. Such information can be used to determine whether the user should stop and retrieve additional growlers or whether there is a sufficient quantity of beer in the housing.
The control unit can be in communications with the remote server and transmit environmental information and other information to a central database 80. The data stored on the database can be aggregated for market analysis to determine information such as most popular beer purchased for a given region, average length of storage time, temperature, average pour time, and much more information. By combining this information with demographic information, valuable market analysis can be performed and access by distillers 82 and retailers 84 and others through as remote location by with electronic communications to the remote server.
In one embodiment, a growler identification reader 101 can be included and in communications with the controller that can read identifying information from the growler. For example, the reader can read a barcode, label, text, graphics, or some combination. The information on the growler can be associated with the time the growler was placed on the housing, content information, such as flavor, brand name, origin, purchase location, and the like. In one embodiment, when information about the fluid in a beverage container it entered, the control unit can transmit a request for additional information to a server. The server can access external databases and retrieve additional beverage information that can be transmitted to the control unit. Such additional information can include purchase information, alcohol content, brewery information, and the like.
