The present invention relates to a container for the preparation of whipped beverages and, in particular, sealed containers, which are made essentially of air - and waterproof material and which contain one or more ingredients to prepare drinks.

Previously it was proposed to isolate the ingredients to make the drink in a separate air-impermeable packaging. For example, packets or capsules containing ground coffee pressed, known for its use in some types of machines for making coffee, which is usually called coffee "Express" (espresso machines). When preparing coffee using these coffee makers, package of coffee is placed in the brewing chamber, and the hot water is usually passed through the container under pressure, due to that ground coffee is extracted aromatic components of coffee and is coffee drink. Usually when preparing espresso requires a pressure of approximately 6×106PA or more at the time of infusion of approximately 25 seconds.

Also known packages containing roasted and ground coffee, through which hot water flows under the action of its weight. The container of this General type described in UK patent No. 1397116.

In the patent EP-A-0272922 described packaging is a, which contains at least one ingredient for the beverage, e.g., roast and ground coffee. In a preferred embodiment, the packaging is made essentially of air - and waterproof material and comprises a sealed portion of the housing having a compartment containing the ingredient of the drink, and outlet channel, and branch and outlet channel interact in such a way that when using the drink is filtered, so it does not need an external filter.

In the document EP-A-0272922 also described the method of preparation of the beverage, which includes the location of the packages containing the drink, the brewing location, the introduction of a package of water through the means of introduction of water, passing water to be mixed with the ingredient of the drink and the collection thus prepared beverage through the outlet hole formed in the package.

6 is a view in section of a container for a drink along the line V-V of figure 5; and

7 is a top view of an additional container for the beverage according to the invention.

As can be seen in figure 1-4, the container according to the present invention in General is shown by the reference number 1. The container mainly made of moulded plastics material and has an upper part 2, which can be decorated, to identify the contents of the capsules, or which may be laminated to foil or a piece of paper with the appropriate identification. The bottom 3 of the capsule may be made of aluminum foil or laminated foil.

The container 1 has an inlet 4 and outlet 5, which are formed during use of the container by perforation or cutting of the material, closing the inlet and outlet.

In use, water under pressure enters the container 1 through the inlet 4, which falls into the channel 6, the OBR is organized along the edges of the packing, and connected through slots 7 with ingredients 8 beverage contained in the compartment inside the container. Water is mixed with the ingredients for the beverage contained within the compartment 9, and then passes up through the ingredients of the drink. Drink, formed by passage of water through the ingredients for the beverage passes through the filter material 10 in a multitude of passages formed between the ribs 12, attached to the filter paper. Attaching the filter material to the ribs 12 prevents any shorting circuit, and the beverage passes through the filter. The passages 11 are closed by remote from the exit ends of the transverse ribs (not shown). The drink is collected through the passages 11, merges into region 14 in the direction shown by the arrows.

Assembled in the field 14 drink passes to a curved collecting space 15, which is connected tapering bore 16 to the expanding chamber 17. The drink under pressure is directed through a tapering hole through the back pressure of the drink, gathering in areas 14 and 15. The pressure within the compartment of the container containing the beverage is usually in the range from 0.7 to 2×105PA. The cross-sectional area tapering apertures is chosen so that sozdatjtakzhe flow of the jet of beverage, component of approximately 3-20 m/s, preferably 8-16 m/s, and more preferably, approximately 10 m/s To achieve a flow rate of 10 m/s typically use a tapering hole cross-sectional area of 0.3 mm2to 0.8 mm2preferably about 0.45 mm2to produce a drink with a volume of 60 ml for 12 C.

The camera 17, which produces a jet of the beverage, is under atmospheric pressure and connected with the field of 18 holes for air intake through the elongated passage 19. The camera 17 is open, as the expansion chamber, and when the pressure of the jet of the beverage is reduced, the air rushes into the drink through the air passage 19. A jet of the beverage, which goes through a tapered hole 16, the hitting surface 20, which is located in the channel flow of the drink. The surface 20, which hits the drink, is located at an angle of 30-35 degrees, preferably at an angle of approximately 33 degrees. The surface 20 has many cut in it grooves 21. The impact of the jet of beverage with grooves 21 contributes to the generation of the turbulent motion of the drink and the saturation of the air in the form of many individual bubbles. The surface 20 is formed on one side of the protruding tongue 22, which serves to channel the flow of drink.

Drink, after the collision with the surface 20, passes around the con is and protruding tongue 22 along the channel 28 to the outlet 5. To save the volume of the bubbles in the drink, a Cup or other vessel should preferably be placed close to the outlet in order to avoid the disappearance of bubbles, when the drink is collected.

Figure 5 and 6 shows an alternative container according to the present invention. Many elements of this alternative container such as the container of figures 1 and 4, and to describe similar elements use the same reference position. Therefore, the beverage in the container 5 is prepared in the same manner as in the container 1. Thus prepared the drink is collected in the field 14 and passes into the collecting space 40, which is connected by a tapering hole 41 to the expansion chamber 42. Collecting space 40 has a socket adjacent to the entrance point into the hole 41, with the aim of minimizing the pressure drop at the entrance to the hole. The drink is directed under pressure through a tapering hole 41 under the action of the pressure of the beverage in collecting areas 14 and 40.

The camera 42, which serves a jet of the beverage, is under atmospheric pressure and is connected to the inlet 43 to the air through a narrow elongated passage 44. The inlet opening 43 for air is located near the exit of tapering holes 41. The camera 42 operates as an expansion chamber and the AC is only the pressure of the jet of the beverage is reduced, through the air passage 44 in the drink directs the air. A jet of the beverage coming out of the tapered hole 41, hits the surface of the chamber 42 under the adjacent fragile approximately 39°.

In contrast to figure 1, the sides of the expansion chamber 42 is made in General smooth. Expansion chamber 42 expands to the area 45 of the slope and then expands in reaching the collecting funnel area 46 immediately before the outlet 47. The outlet hole 47 provided with a rib 48 to prevent spraying and/or splashing of the beverage at the exit from the container.

The General form and design of the expansion chamber 42, zone 45 of the slope and collecting region 46 are smooth flowing curves, to prevent unwanted turbulence by passing the drink to the outlet 47, to prevent the destruction of bubbles during the final stage of movement of the beverage to the outlet.

The elements of this container, which is the same as the containers on figure 1-4 or 5 and 6, presents a similar reference positions. Therefore, the beverage in the container 7 is prepared in the same manner as in the container 1. Thus prepared the drink is collected in a region 14 and the passage of the t in the gathering space 50, connected tapering tip 51 to the expansion chamber 52. Collecting space 50 has the shape of a funnel, allowing the prepared drink seeps into the container through a tapering tip 51. The drink is directed under pressure through a tapering tip 51 under the action of the pressure of the beverage in collecting areas 14 and 50. The camera 52, which served the drink, is under atmospheric pressure and is connected to the two intake ports 53 for air through narrow passages 54. The inlet 53 to air feature on both sides from the output 55 of the tip 51 in the expansion chamber 52. The camera 52 operates as an expansion chamber, and as soon as the pressure of the jet of the beverage is reduced, the air rushes into the drink through the air passages 54. A jet of the beverage coming out of the output 55 of the tip 51, hits the surface of the expansion chamber 52 in front of the exit angle of approximately 49°.

Expansion chamber 52 has a General arcuate shape, and the shape and design are smooth flowing curves, to prevent unwanted turbulence by passing the drink to the outlet 47. This prevents the destruction of bubbles during the final stage of movement of the beverage to the outlet 47. Outlet sabrinasabrok 48 to prevent spraying or splashing of the beverage, when he comes out of the container.
