     FIELD OF THE INVENTION 
       [0002]    The disclosure herein relates to a portable capsule percolator with a drinking cup. In particular, the disclosure relates to a portable and easy to use capsule percolator operable, using readily available capsules, for making a desired percolated beverage such as coffee, tea, vegetarian drinks and the like, on the go, at the office, while travelling and more. The portable capsule percolator is operable by a pressure differential mechanism without the need of a power source. The portable capsule percolator includes an air-extracting mechanism operable to extract air from a first internal space and a sealing mechanism associated with the flask lid section configured to let outside air into a second internal space generating the pressure differential, activating the percolating process by pushing the liquid through a beverage capsule into a percolating section. 
       BACKGROUND OF THE INVENTION 
       [0003]    The invention of coffee pods and capsules have revolutionized coffee drinking and have fueled the increasing popularity in the past years of one of the most distinctive beverages available. A coffee pod or capsule is basically an amount of coffee held within a small container, where the container is then entered into a coffee maker and brewed. The simplicity and ease of use of a single shot of coffee brewed with little to no cleanup is appealing to consumers all over the world. The differences in the two lie mostly in the construction of the pod/capsule. Capsules are usually a plastic or aluminum container top sealed with an aluminum or plastic foil which holds the coffee grounds and filter within. A coffee pod is simply a “bag” that is constructed from a coffee filter that is filled with coffee grounds. No matter how you cut it, be it a coffee pod or capsule you are simply pushing water through coffee grounds to create coffee. The systems used for capsules and pods are different systems and even with capsules, each system is commonly associated with a capsule housing according to the relevant capsule dimensions, and therefore are not interchangeable with other systems. 
         [0004]    The usage of capsules expanded into to a variety of beverages of tea, coffee, chocolate, cappuccino, vegetarian drinks and more capsules and a dedicated machine are growing in their popularity, becoming increasingly widespread and provide something for every taste and occasion. 
         [0005]    There are a number of techniques in brewing coffee. Percolating is one such common technique and as stated, percolating while using a beverage capsule expanded to a variety of drinks. Specifically, brewed coffee refers to any method of coffee preparation where hot water comes in contact with coffee grounds for an extended period of time. Percolation involves a solvent passing through a permeable substance especially for extracting a soluble constituent. In the case of coffee-brewing the solvent is water, the permeable substance is the coffee grounds, and the soluble constituents are the chemical compounds that give coffee its color, taste, aroma, and stimulating properties. In simple terms, if coffee percolates, or if one is percolating it, it is made in a container in which hot water passes through a beverage powder 
         [0006]    In 2015, Americans who drink coffee consumed about 1.7 cups a day on average, up from 1.4 cups a decade earlier, according to an estimate by New York-based researcher Study-Logic. 
         [0007]    Generally, coffee is best when freshly prepared. To prepare fresh percolated coffee typically requires a power source to heat water and to maintain a pressure differential which drives the hot water through the coffee. There is no way to make percolated coffee in a handheld drinking cup. 
         [0008]    There is a need for a portable capsulate percolating device that conveniently provides ‘on the go’ ability to prepare easily freshly made beverages such as coffee, but also including tea, vegetarian drinks and the like, without the need of a power source to continually keep the liquid at a desired temperature.) 
         [0009]    The invention below addresses the above-described needs. 
       SUMMARY OF THE INVENTION 
       [0010]    It is an advantage of the current disclosure that it may improve preservation of the freshness, taste and natural appearance of a percolated beverage such as coffee, tea, vegetarian drinks and the like using a portable drinks percolator configured to use a pressure differential mechanism to activate the percolating without the need of a power source. The portable drinks percolator includes an air-extracting mechanism operable to extract air from an upper internal space formed by a percolating section and an upper cap assembly section. The percolator further includes a sealing mechanism associated with a flask lid section comprising a body sealable aperture configured to let outside air into a first internal space formed by the flask lid section and a liquid reservoir section, thereby activating the beverage percolating process.

Additionally, the body sealable aperture uses a sealing mechanism operable to disengage the first sealing element. Variously, the sealing mechanism is selected from a group including of: a push button, a sealing ring, a sealing handle and combinations thereof. 
         [0017]    As appropriate, the pressure differential is generated by activating the air-extracting device to extract air from the upper internal space (the second internal space) and further allowing outside air into the lower internal space via said sealing mechanism thereby activating beverage percolation.

The air-extracting mechanism  614  is configured, for example, to generate linear motion of the extraction plunger  614   b  by the activator  614   a , activated manually by a user and further pushing the air out through the upper cap assembly section. 
         [0085]    The closure lid  616  is configured to clip onto the upper cap lip  612   b  by a “U” shaped locking element  616   d  to tightly cover the drinking aperture  612   e  of the sealable outlet  612   d , when the closure lid  616  is engaged (closed position). Additionally, the closure lid  616  is operable to change state, rotating over the hinges  616   b  and  616   c  to disengage. As appropriate, to enable drinking, the “U” shaped locking element  616   d  needs to be flipped over to unlock the cover lid  616  from the upper cap lip  612   b  and uncover the drinking aperture to allow air into the upper internal space and to facilitate drinking or pouring.
