The use of cartridges or capsules for enclosing substances has increased over the past few years. These substances include edible materials, ink, smokable materials, etc.
For this reason, numerous patents and patent applications have disclosed various designs and uses of containers for enclosing the said type of substances, for instance, a beverage filter cartridge comprising a cup portion; a lid portion coupled to the cup portion to define an interior; and a filter member provided within the interior; wherein the cup portion, the lid portion, and/or the filter member define three separate compartments with the interior. Also US2010/0077928 discloses such a capsule.
The European patent no. EP2298671 discloses a disposable capsule for beverage dispensing machines for preparing a beverage from a food product housed within it, comprising a plurality of walls, means for dispensing said beverage, and at least an element for partitioning the internal volume of the capsule into two or more volumes to house at least said food product, said partition element being spaced with respect to the wall of the capsule provided with said beverage dispensing means, wherein the means for dispensing said beverage comprises a trap or an opening sealed by a film that are pierceable by a piercing element, and wherein said partitioning element has a supporting surface that is substantially abutting said piercing element, in order to be supported by said piercing element during dispensing of beverage.
The European patent no. EP1980501 pertains to a capsule for preparing drinks by passing a liquid through a powdered substance contained in a chamber made inside the capsule, the capsule comprises a cup-shaped structure having a lower wall; the chamber being delimited on at least one side by at least one filter element having a plurality of through-holes extending from a first face of the filter element facing the inside of the chamber, to a second face of the filter element facing the lower wall of the cup-shaped structure, the through-holes have inlet sections extending according to a main trajectory of extension and each having a length, measured along the main trajectory of extension, greater than their width, measured transversally to the main trajectory of extension.
In the prior art is also disclosed a cartridge for containing smoking materials, the cartridge comprises a container formed from one or more foils; a smoking material within the container; a top joined to the outer container to capture the smoking material within the outer container; and at least one thermally conductive panel between the smoking material and the top, wherein the panel is spaced from the top.
The European patent no. EP1702525 discloses a tobacco cartridge for use with a narghile or other smoking appliance having a tobacco bowl for receiving tobacco, comprising: a quantity of tobacco enclosed within an enclosure, said enclosure having a lower end configured for applying the cartridge to the tobacco bowl of the smoking appliance, and an upper end which is openable to provide access to the tobacco for igniting same, the enclosure further includes a body of a combustible material capable, when ignited, to produce a glowing ember for igniting the quantity of tobacco within the cartridge.
The prior art conventional solutions do not allow for even distribution of heat to the ingredients enclosed in the cartridge, and do not allow for an internal fluid vortex within the cartridge.

Summary of the invention

Therefore, it is an object of the present invention to have a multi-compartment cartridge that for enclosing at least one substance, wherein such cartridge allows for even distribution of heat to the ingredients enclosed in the cartridge, and allows for a creation of an internal fluid vortex within the cartridge.
