Description

Filter holder for espresso coffee maker.

Object of the invention

The present invention relates to a espresso coffee filter holder, of the type that includes a bowl for housing the coffee, presenting said bowl: a coupling to the shower neck or water spout own hot of the coffee maker, a means of internal filtering and a side grip handle.

Background of the invention

Currently, for the preparation of espresso coffee coffee machines with a small boiler are usually used and that they put hot water under pressure through the ground coffee deposited in the bowl of a filter holder. The coffee maker comprises a coupling neck in which there is a rack or shower by the hot water comes out to a filter holder arranged below and coupled to the neck of the coffee maker through a coupling of spin, usually bayonet.

This filter holder comprises a bowl with a internal filter and an outlet hole of the coffee made. The bowl internally defines a hole in which the ground coffee, to prepare the infusion.

On the other hand, lately they have become popular the known unit doses of coffee, which are constituted by a container containing the ground coffee necessary to make a cup of coffee approximately, allowing said container to pass through its hot water inside. Coffee preparation with these unit doses require the use of specific machines that have a filter holder suitable for dimensions and geometry of the doses and of a shower or hot water dispenser, also of dimensions also consistent with the dose surface ground coffee container.

These particularities are a problem for those users who already have a suitable coffee machine for the preparation of espresso with ground coffee in bulk, taking into account that the unit doses existing in the market cannot be adapted properly to the filter holders conventional espresso machines and that these doses have a surface area significantly smaller than shower or water spout Hot from espresso machines.

Therefore, the problem that arises is the development of a filter holder that is adaptable to machines existing express and that allows the use of unit doses of coffee, so that those users who have a machine of espresso coffee can use unit doses for the preparation of coffee, acquiring only the filter holder and without the need for Buy another coffee maker.

Description of the invention

The filter holder for espresso machines The present invention has technical characteristics oriented to allow the use of a type of dose encapsulated coffee, existing in the market, and a correct coupling both the dose and the filter holder to a coffee maker or conventional espresso machine, also solving other additional problems such as adapting the useful surface of the shower of the coffee maker to the surface of the dose, so that prevents the accumulation of excess water inside the filter holder, around the dose.

The portafilter for espresso coffee machine object of the invention is one of those comprising a bowl with means suitable for coupling with the shower neck of a conventional espresso machine, a grip handle, an opening upper for hot water inlet supplied by the shower the espresso machine, an inner receptacle with a suitable filter and a bottom hole for the brewed coffee outlet.

According to the invention this filter holder it presents a surrounding stepped inside the bowl, on which an annular joint, of dimensions, is mounted suitable for the support of a peripheral portion of a dose unit of coffee, of the existing ones in the market, and its pressed against a peripheral portion of the shower, so that said gasket annular, in the position of use, seals a perimeter zone of the shower, bringing the useful surface of the shower, through which it will come out the hot water, coincides with the central area returned from the dose, in which the coffee is housed.

This board presents a central passage for the accommodation of the returned part of the said unit dose of Coffee and hot water circulation. In turn, the stepped found slightly distanced from the upper mouth of the bowl, leaving the gap between the stepped and the shower fully occupied by the board.

The joint has a superior contour interior recess or seat for coupling the unit dose, making a correct adjustment.

In turn, the filtering media are found positioned internally at the bottom of the bowl and comprise a filter mounted on an annular support.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

- Figure 1 shows a sectional view of a embodiment of the filter holder, facing the shower or hot water dispenser of a conventional espresso machine, having represented a unit dose of both elements coffee, of the rigid capsule type, attachable to said filter holder.

- Figure 2 shows a view similar to the anterior, and in which the filter holder and inner seal have a suitable configuration for the use of a different type of unit dose of coffee.

- Figure 3 shows an exploded view in perspective of any one of the filter holders of the figures above, with the ring seal and the filter media removed inside the filter holder bowl.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the filter holder for espresso coffee maker comprises a bowl (1) with lateral thickeners that make up some coupling means, by turning, to the neck (21) of the shower (2) or hot water dispenser typical of an espresso machine conventional, said bowl (1) presenting filtering means bottom, a hole (12) for coffee outlet and a side handle (13) asido.

Inside the bowl (1) there is a surrounding step (14) in which an annular seal is arranged (3) for the support of the contour of a specific type of dose unitary coffee (4) and its pressed against the shower (2) of the coffee maker.

Said ring seal (3) comprises a passages or central hole for housing the central area returned of said dose (4) and for the passage of hot water provided by the shower (2), through the dose (4), towards the bottom of the bowl (1).

The ring seal (3) presents superiorly, in its interior contour, a recess or perimeter seat (31) for the tight coupling of the unit dose (4) of coffee.

The upper surface of the joint (3) acts against a peripheral area of the shower (2) performing its shutter, so that hot water can only come out of that central area of the shower (2) facing the area Registered dose (4) and containing ground coffee.

As shown in Figures 1 and 2, the ring gasket (3) and the inner cavity of the bowl (1) can present different geometries, depending on the dose unit (4) to be used in the filter holder, be it container type or capsule, as shown in figure 1, or discoidal bag type, as depicted in figure 2.

In any case, the filter holder will have outwardly of prominences to allow their coupling with the shower neck of a conventional espresso machine, and inside the surrounding step (14) for the seat of the annular joint (3) that allows the correct positioning of the dose (3) and establishes a tight seal against the shower of the coffee maker in the position of use.

The filtering means comprise a filter lower (11) and a lower support (11a), annular configuration, provided with some upper studs destined to stay in some complementary holes of the filter (11a).

Once the nature of The invention, as well as a preferred embodiment, is for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
