Pack for preparing foamed food or beverage products

Abstract

The invention refers to a pack (100) for preparing a food or beverage product from one or more food or beverage ingredients comprising an insert (10) and a container (20) where the ingredient or ingredients are stored, the insert (10) comprising a fluid inlet (110) configured for introducing an aqueous fluid under the form of a jet (50) in the inner volume of the pack, and the insert (10) further comprising an air inlet (150) communicating with the exterior of the pack (100) and configured for introducing air in the inner volume of the pack (100). The invention further refers to the use of a pack (100) as described for preparing a food or beverage product.

1 . Pack for preparing a food or beverage product from one or more food or beverage ingredients comprising: an insert and a container where the ingredient or ingredients are stored;
 the insert comprising a fluid inlet configured for introducing an aqueous fluid under the form of a jet in the inner volume of the pack; and   the insert further comprises an air inlet communicating with the exterior of the pack and configured for introducing air in the inner volume of the pack.   
     
     
         2 . Pack according to  claim 1  wherein the air inlet is connected to an aspiration inlet through which the jet enters the inner volume of the pack, configured in such a way that air is aspirated through the air inlet when the jet is introduced inside the pack. 
     
     
         3 . Pack according to  claim 1  wherein the air inlet is connected to an aspiration inlet through which the jet enters the inner volume of the pack, the air inlet being connectable to external means actively injecting air in the inner volume of the pack. 
     
     
         4 . Pack according to  claim 1  wherein the fluid inlet is configured for transforming the pressurized fluid introduced by a beverage machine into a high velocity fluid jet in the inner volume of the pack. 
     
     
         5 . Pack according to  claim 1  wherein the fluid inlet communicates with a nozzle having a very restricted diameter with respect to the fluid inlet. 
     
     
         6 . Pack according to  claim 1 , comprising two flexible water impermeable sheets joined to one another to define the inner volume of the pack. 
     
     
         7 . Pack according to  claim 1 , comprising a beverage outlet through which the beverage is delivered as a free flow. 
     
     
         8 . Pack according to  claim 7  wherein the beverage outlet is a straight tube oriented essentially vertically at the bottom of the pack. 
     
     
         9 . Pack according to  claim 7  wherein the insert is arranged on one of the sides of the pack and it comprises the fluid inlet the air inlet and the beverage outlet. 
     
     
         10 . Pack according to  claim 1  wherein the container is configured to open in a certain pre-defined area to allow dispensing of the food or beverage prepared. 
     
     
         11 . Pack according to  claim 2  wherein the relative positioning of the aspiration inlet with respect to the air inlet, together with the diameter of the air inlet, define the level of foaming of the food or beverage prepared. 
     
     
         12 . Pack according to  claim 2  wherein the diameter of the nozzle and/or of the aspiration inlet define the design of the jet in the inner volume of the pack. 
     
     
         13 . Pack according to  claim 1  wherein the food or beverage ingredient is a soluble food or beverage ingredient. 
     
     
         14 . Pack according to  claim 1  wherein the container is configured as a sachet, a capsule or the like. 
     
     
         15 . Pack according to  claim 1  wherein the fluid inlet can be accessed frontally and/or by the rear to introduce an aqueous fluid through one or the two sides. 
     
     
         16 . Pack according to  claim 1  wherein the air inlet obturation can be regulated in order to control the quantity of air injected. 
     
     
         17 . Pack according to  claim 1  presenting a plane shape oriented along a plane essentially vertically oriented during beverage production and the fluid inlet orientates the jet of fluid in a direction comprised in said plane.
