DISPOSABLE CARTRIDGE FOR USE AS A FILTER IN PARTICULAR FOR INFUSIONS OF SOLUBLE ELEMENTS, AROMATIC HERBS SUCH AS TEA, COFFEE, CHAMOMILE, ETC.

A disposable cartridge for use as a filter in particular for soluble elements, aromatic herbs such as tea, coffee, chamomile, infusion, whose configuration comprises means for securely and stably fixing it without occupying the entire annular diameter of a cup or container, characterized in that it is made up of a symmetrical laminar template (2) whose plantar shape is determined by an upper area of sinusoidal contours (3) with a superior central ridge or rounded tongue (4) followed by curved shoulders (4a) is the middle area of which it is present a groove or opening of oblong configuration (5) with rounded ends (6), which serves as means for cartridge holding (1) with the cup (8) upper perimetric rim (7) in which the lower area of the template (2) has a triangular obtuse-angled body (9) with straight sides (9a).

BACKGROUND OF THE INVENTION

The present invention relates to a disposable cartridge, for use as a filter, especially for soluble elements infusion, aromatic herbs such as tea, coffee, chamomile and others, formed with a laminar template, provided with a perimeter tongue, an upper opening or slot for fixing or holding a cup or any unwanted element, in an upper perimetric rim which allows to improve and avoid the use of other elements for its fixation or holding.

In attention to the state of the art cartridges, especially for soluble elements infusion, we can cite the invention patent CL No.49.144, which refers to a disposable cartridge, for use as a filter, especially for soluble elements infusion, aromatic herbs such as tea, coffee, chamomile, whose configuration comprises means to securely and stably hold it without occupying the entire diameter of a cup, characterized in that it is formed with a laminar template (2), divided into three straight contours sections, a center section (3), which constitutes the container (4) and two obliquely disposed side sections (5), which overlaps to constitute a straight back wall (6); said obliquely arranged side sections (5) are provided with an extension or section (7) that overlaps constitute handle (8), both being provided with a tongue, a minor clamping tongue (9) and a larger upper tongue (10), both are the attachment means to a cup (12) annular ring (11) or the like.

Another invention is the document ES 2 195 481, which relates to a beverages infusion filter, in particular for a coffee filter and to a method for the manufacture of this kind of filters, where a fibrous material with pores used with a minimum pore opening (d) of around 0.1 mm measured with a fiber density that accounts for approximately 50% of the original fiber density of the material, the average pore opening (d) is preferably in a range of around 0.1 mm to around 0.7 mm and more preferably in a range of around 0.1 mm to around 0.4 mm, the material is referably paper, the pores are further preferably formed by means of needle punching or fibrous material water et injection, in this way a non-sharp pore rim is formed.

In view of currently existing deficiencies and disadvantages, with the cartridges used to filtering and to prepare aromatic herbs, a cartridge has been created with a single body and division's template, much is more practical for its manufacture and use, and equipped with a different fixing system and stay sustained in its cup attachment or fixation.

DESCRIPTION OF THE INVENTION

According toFIGS. 1 to 8, the aromatic herbs infusion conical cartridge (1), is formed with a symmetrical laminar template (2), whose planar shape is determined by an upper zone of sinusoidal contours (3), with a superior central ridge or rounded tongue (4), followed by curved shoulders (4a), in whose middle zone has an oblong slot or opening configuration (5) with rounded ends (6), which serves as means of cartridge attachment or fixation (1) with the upper perimeter flange (7) of a cup (8); the template lower area (2) has a triangular obtuse-angled body (9), with straight sides (9a) of the lower vertex angle or legs or chords being 128° and the lateral vertex angles are 70°, being provided in one of the legs or chords of the triangular obtuse body (9) with a trapezoidal flap (10), which allows sealing and joining the sides of the legs or chords and forming the conical body cartridge.

For the cartridge assembly (1), only one fold of the template (2) must be done through the symmetry A-A axis until it is overlapped with the trapezoidal flap (10); then to fix the cartridge (1) in the cup (8) the rounded tongue (4) must be folded downward to but with the oblong opening (5) so that said 8% opening is fxed with the perimeter flange (7) of the cup (8) thus leaving the cartridge (1) located parallel to the wall of the cup (6).
