Breaking system applied in capsules for espresso machines, tea and other solubles, made of thermoplastic material, aluminium or its derivatives

Abstract

Breaking system to be applied in the area where the water enters and the infusion exits the capsule. The surface from the bottom of the cup presents interior creases, reducing the thickness of the wall and limited areas of rupture or breaking, that is caused by the normal pressure water pump. The cover produced in the same material, presents in the central surface lowered, creases of rupture or breaking, that can be in the same quantity and equal to the bottom of the cup, or different, with a geometry and appropriate quantity to the granularity of the products introduced into the capsule. The outside of the wall of the cup presents raised ribs, that form rhombs filled with raised dots. By the inside of the wall of the cup is reinforced with three or more platelets amounts.

1 . Breaking system to be applied in capsules for espresso machines, tea and other solubles, made of thermoplastic materials, aluminium or their derivatives, which is characterized by being composed by creases ( 1 ) applied in the area where the water enters ( 11 ) by the inside of the bottom of the cup ( 7 ) and in the area where the infusion exit ( 4 ), on the cover of the capsule ( 2 ), or just in one of that areas, the area where the water enters ( 11 ), by the exterior of the bottom of the cup, which is a central surface circular recessed, smooth and fully closed, which is surrounded by a protruding peripheral circular crown ( 10 ) to create a large sealing surface when the bottom of the cup ( 7 ) engages to the housing of the machine, by the interior of the bottom of the capsule cup, the central surface ( 11 ) presents creases ( 1 ) with straight or curved shapes, which join at the center and are produced to reduce the thickness of the material into a thin film, that resist the handling of the capsule safely, and allows that the breaking ou rupture is caused by the water when this one is injected by the normal pressure of the water pump that manning the machine. On the opposite side, in the mouth of the cup ( 7 ) or in the area where the infusion exits, it's applied one cover ( 2 ), that is made in the same material of the cup, which is applied to the cup and closed with total airtight seal, the cover ( 2 ) presents a flap ( 9 ) more high and peripheral, with concentric grooves causing various circular crowns with various widths, but all with the same level to sealing by abutment the capsule accommodation in the machine, being the external circular crown ( 3 ) with bigger diameter and larger, the central circular surface ( 4 ) surrounded by the flat ( 9 ) is smooth and totally closed by inferior side of the cover, and by the superior side on the external side of the cover, the surface ( 4 ) is slightly recessed, presents the creases ( 1 ), with a straight our curved shape that limited the areas of the breaking or rupture to the exit of the infusion, the geometric configuration and the number of creases ( 1 ) of the cover breaking, can be in the same quantity and equal as the bottom of the cup, or be different, in more or less quantity, to form geometric figures, that are areas or lamellae of rupture more or less shapely or prepared, and in size and number appropriated to the volumetric characteristic of granularity or the particles of the product that fills the capsule, and by the way, the lateral external wall ( 5 ) of the capsule cup ( 7 ) presents a rough texture composed by multiple raised ribs, rectilinear and forming rhombs, where inside of them are made multiple points also in raised and produced by the molding during the manufacturing, the wall of the cup ( 7 ) by the interior side is reinforced with three or more amounts or plates ( 6 ) with more thickness that the wall of the cup, that are amounts of reinforcement of the lateral wall when the capsule is placed and compressed on the inside of the housing in the machine, the reverse area of the flap ( 9 ), in the flange have a reversed trapezoidal shoulder for a hermetic sealing of the cover in the flange of the flap ( 8 ) of the cup ( 7 ), and also presents by the same reverse side, others symmetrical recesses and raises to the flap ( 9 ), to reinforcement and resistance in the act of buffering. 
     
     
         2 . Breaking system to be applied in capsules for espresso machines, tea and other solubles, made of thermoplastic materials, aluminium or their derivatives, that according to the  claim 1  is characterized by being applied by the inside of the bottom of the cup ( 7 ) in central area ( 11 ), and by the exterior of the cover ( 2 ) on the central area ( 4 ) being the cover and the cup, both produced in the same material, where the cover ( 2 ) may present breaking creases ( 1 ) in same size, quantity and placement or in different quantities and placements of the creases ( 1 ) that are applied in the bottom of the cup ( 7 ). 
     
     
         3 . Breaking system to be applied in capsules for espresso machines, tea and other solubles, made of thermoplastic materials, aluminium or their derivatives, that according to the  claim 1 , characterized by being applied in the cup ( 7 ) of the capsule and in the cover ( 2 ) of the capsule, and the capsule with this breaking system being used in the ordinary pressure espresso machines, being in this case previously placed a centering ring in the cavity of the handle of the espresso machine were usually put the coffee in bulk, and then the capsule is placed inside the ring in the cavity of the handle. 
     
     
         4 . Breaking system to be applied in capsules for espresso machines, tea and other solubles, made of thermoplastic materials, aluminium or their derivatives, that according to the  claim 1 , characterized by being used in the cup ( 7 ) and in the cover ( 2 ) of the capsule, or just in the bottom of the cup ( 7 ), being then the cup closed for a tamponed in silver or in aluminium foil, filter paper, or in micro perforated plastic commonly used in the market.
