Coffee is a favorite beverage enjoyed around most of the world, after harvesting green beans from coffee trees, processing them, roasting them, mixing one or more different variety of coffee beans, and extracting it. There are various methods in extracting coffee, including but not limited to, immersion method, filter filtration method, vacuum filtration method, pressure extraction method, and the like.
Immersion is a method of brewing in water at room temperature, cold or hot water. Filter filtration is a method of extracting coffee by pouring hot water on the filter containing coffee powder; extraction containers are used such as drip-coffee machines or hand drip. Vacuum filtration is using steam pressure and It is a method of extraction using the osmotic pressure of water. The pressure extraction method is a method of rapidly extracting soluble components by passing hot water through the coffee layers under pressure.
Meanwhile, as consumers become more experts in coffee making, the consumers increasingly want higher-quality coffee. As a result, cold-brew coffee, which retains its flavor longer, stays fresh longer and distributes more conveniently than other coffees, is gaining popularity. Although there is no known orthodox history on or the origin of cold brew coffee, it is generally known that it is a method devised by sailors for drinking coffee on board while transporting Dutch Indonesian Robusta coffee to Europe.
Recently, nitro coffee, the smooth texture, foam created and flavor of which can be enjoyed for a long time by mixing cold brew coffee with nitrogen like draft beer, is becoming increasingly popular. In the case of nitro coffee, a high-pressure nitrogen filling device is required to inject nitrogen into cold brew coffee, so there is a limit to consumers making and drinking it themselves. Accordingly, in order to enjoy nitro coffee conveniently by consumers, a beverage container filled with liquid beverages such as coffee and high-pressure nitrogen gas has been developed.
In this configuration, because the user has to support the fixing cap 20 with his or her pinky finger, it is difficult for the user to press the pressure vessel 10 with the thumb, especially a weak pinky finger holding the fixing cap. Therefore, the present invention strives to solve the problems of the prior art as described and provide a nitro beverage container that allows the beverage accommodated in the container body to be easily sprayed to the outside.

These and other features, aspects and advantages of the container will become better understood with reference to the accompanying drawings, wherein:
An improved container is described in detail as shown on the Figs.
The container body 100 is formed in a long bottle shape and has a size that can be easily gripped by a user by hand. The container body 100 may be formed of a transparent material so that the contents inside can be seen from the outside. A space is provided inside the container body 100 to be filled with a beverage liquid such as coffee and a high-pressure gas such as nitrogen. And the upper side in the longitudinal direction of the container body 100 is opened.
The lid 200 is formed to close the open upper side of the container body 100. A through hole 202 is formed in the center of the lid 200. The nozzle 300 is formed in a long tube shape along the longitudinal direction and is positioned so as to be movable up and down while being inserted into the through hole 202. And a valve (not shown) is installed at the inner end of the nozzle 300 positioned inside the container body 100.
The valve normally closes the inner end of the nozzle 300. When force is applied to the outer end of the nozzle 300 protruding to the outside of the container body 100 by the pressure by the pressing member 400, the nozzle 300 presses the valve. Upon the nozzle pressing onto the valve, the valve opens and the beverage solution and high-pressure gas inside the container body 100 are discharged to the outside through the nozzle 300. The valve is a known technology; therefore, a more detailed description is not necessary. The cap 150 is coupled to the container body 100 so as to cover the pressing member 400.
A convex portion 414 is formed to protrude in the direction of the nozzle 300 at the center of the inner surface of the housing 410 positioned to face the nozzle 300. The guide groove 414a is concavely engaged in the convex portion 414. A discharge hole 416 is formed through the center of the bottom surface of the engaging guide groove 414a. The bottom surface of the engaging guide groove 414a may be formed to gradually decrease in cross-sectional area toward the center.
The discharge hole 416 is formed to have a smaller diameter than the nozzle 300. When the side wall portion 417 is coupled to the lid 200, the outer end of the nozzle 300 is positioned so as to be caught on the edge of the bottom surface of the engaging guide groove 414a in a state inserted into the engaging guide groove 414a. The sliding portion 414b is formed to be inclined along the inner peripheral end of the engaging guide groove 414a facing the lid 200, and the outer end of the nozzle 300 slides along the sliding portion 414b in the direction of the bottom of the engaging-guide groove 414a.
A discharge-guide groove 415 is formed concavely in the direction of the engaging guide groove 414a in the center of the pressing surface portion 412 located in the opposite direction of the nozzle 300. That is, the discharge-guide groove 415 is formed from the pressing surface portion 412 towards the discharge hole 416 located at the center bottom of the discharge-guide groove 415. The discharge hole 416 is also located at the center of the pressing surface portion 412.
The beverage solution and nitrogen gas are discharged from the nozzle 300, through the discharge hole 416. Because the beverage 55 and the nitrogen gas 60 being discharged are guided by the nozzle 300 and by the center of the discharge-guide groove 415 and the discharge hole 416 therein, the beverage and the gas are guidely discharged from the container body 100. The beverage and the gas discharged are guided and uniformly ejected by the pressurized gas from the container body, the beverage is not splattered unnecessarily and retained by the cup.
The guide groove 420 is to guide the placement of the user's finger. The guide groove 420 is configured as a pair and are located in the opposite direction of the lid 200. On two sides between the pressing surface portion 412 and the side wall portion 417 of the housing 410, the guide grooves 420 are concavely formed so that the fingers of the user may be placed upon the guide grooves 420. The guide groove 420 has a first guide part 422 near its adjacent side wall portion 417 and second guide part 424 near its adjacent pressing surface portion 412. The surface of guide groove 420, flowing from the pressing surface portion 412 to the side wall portion 417 form a concave arc shape. The concave arc shape is designed to better accommodate the fingers of the user.
For example, when an index and a middle finger of the user are respectively guided to the pair of guide grooves 420, the inner surface of the index finger and the inner surface of the middle finger, facing the palm of the hand, are on the pair of first guide parts 422, respectively. The side of the index finger and the side of the middle finger facing each other are also placed on or near the second guide part 424, respectively. As such, because the fingers are stably mounted on the pair of guide grooves 420, the housing 410 can be stably pressed in the direction of the container body 100 with the pair of fingers. Moreover, because the guide groove 420 is configured not to protrude from both sides of the container body 100, it has excellent portability.
The locking portion 418 is formed to protrude from the lower end of the inner periphery of the side wall portion 417 located in the opposite direction of the pressing surface portion 412. The lid 200 is hooked on the locking portion 418 to be securely attached.
The nozzle 300 is inserted into the engaging guide groove 414a. And a stopper 419 is formed to protrude from the lower end of the inner periphery of the side wall portion 417 in a position spaced apart in the direction of the pressing surface portion 412. Accordingly, when external pressure is applied to the guide groove 420 and the pressing member 400 is moves downward, the stopper 419 is moved into the lid 200 direction so as to be closer to the lid 200. The upper surface of the lid 200 engaging the stopper 419 limits the downward movement of the pressing member 400.
When the external pressure applied to the guide groove 420 is removed, the pressing member 400 moves upward and the lid 200 is again catches the locking portion 418. Because the lid 200 is caught between the locking portion 418 and the stopper 419, the pressing member 400 may not arbitrarily removed from the container body 100. Thus, the pressing member 400 is an integral part of the container 50, and there is no need to carry it separately or be stored away separately.
The inside of the lid 200 covering the container wall 110 is formed to cover the inner skin (not shown) of an elastic material, so that the inside of the lid 200 is at the longitudinal end of the container body 100. When coupled with the lid 200, the fastening protrusion 112 is positioned so as to be embedded in the inner skin of the lid 200. The inner skin may be made of, for example, silicone. Also, the inside of the lid 200 is coupled to cover the longitudinal side of the container body 100. The inside of the lid 200 has binding protrusions (not shown) and when lid 200 caps the container body 100, the binding protrusions (not shown) of the lid at the inner walls of the lid are fit into the binding grooves 122. Because the fastening protrusions 112 are configured to be firmly embedded in the inner skin and the binding protrusions are inserted into the binding grooves 122, the lid 200 is firmly and tightly coupled to the container body 100. Because of the secure enclosures, high-pressure gas accommodated in the body 100 is safely stored along with the beverage. Because of multiple interlocking enclosure functions, the container body 100 could handle the pressure as the pressure of the gas inside the container body 100 increases even at elevated temperatures, accommodating the high temperature of the summer season.
