Cap for capsules Object of the invention

The object of the present inventions is a novel cover for those capsules of coffee or other beverages that can be adapted to any type of machine, preferably to those machines that introduce the liquid, generally water, through a central hole and the beverage leaves of the capsule through holes arranged circularly to said central hole. In addition, the capsules incorporating the invention may be filled at the factory or by the end user and may be filled by said end user as many times as desired, whereby the cost of coffee or beverage is considerably reduced.

Background of the invention

The use of the well-known beverage preparation machines that use capsules has become popular in recent years, mainly for the preparation of coffee, infusions or other types of beverages, since for the consumer they are very easy to use and for suppliers of coffee or other ingredients greatly increase the benefits per dose of drink.

Each manufacturer designs its machine so that only one type of capsules can be used, the design of which is its own, so they not only obtain benefits from the sale of machines but mainly from the sale of the capsules

Generally, the operation of this type of machines is that when the capsule is introduced in the appropriate place of the machine, it detects what type of beverage it has to prepare and at the same time it performs a series of perforations in the capsule lid through which it is introduced water to mix with the ingredient inside and produce the desired beverage that leaves the capsule through the same hole or by others

One of the aforementioned drawbacks, the recognition of what type of beverage the machine has to prepare, has already been resolved by the same author of the present invention and is described in the utility model whose title is “Perimeter reading system applicable to

capsules ”and which is applicable in capsules incorporating the" capsule cap "described in the present application.

Description of the invention

The capsule lid, which is the object of the present invention, is intended to close those capsules comprising a container containing an ingredient for a beverage, said container is formed by a side wall, a bottom base, a collar flat, whose shape is a circular crown, is disposed on the edge of the container and is intended to be attached to the lid by a procedure suitable to the materials of the lid and the capsule, for example by adhesives or heat seals. The capsule lid, whose shape is circular, comprises one or more layers joined together by at least their perimeters, at least one of the layers of said layers has a plurality of weakening lines, the shape of which is open, distributed in the inside of a concentric circle with the lid and whose radius is smaller than the inner radius of the mentioned flat collar of the capsule.

Although it is evident, the function of the weakening lines is to break when a pressure is exerted on them to allow the entry and exit of the liquid, and its shape is open, for example in the form of U, T, L or any another, so that when the line of weakening is broken there are no fragments that can be introduced into the interior of the capsule and mixed with the ingredient, or mixed with the drink once prepared by falling next to it in the glass or similar container.

Preferred Embodiments

The capsule cap, which is the object of the present invention, is attached by any suitable procedure to the capsule (9) containing the ingredient that together with the water injected into the capsule (9) produces the desired beverage. Said capsule (9) is formed by a side wall (10), a lower base (14) and a flat collar (11) disposed on the edge of the container. The cap is attached to the flat collar (11) of the capsule (9) by any procedure depending on the materials used in the cap and in the capsule, said procedure can be glued, melted or any of the various heat welding methods. Of course, all the materials used, both in the capsule and in the lid are materials suitable for food use.

The shape of the lid can be flat, concave or convex depending on the ingredient and the machine.

The invention comprises at least one circular layer (1) having a plurality of weakening lines (2, 3) on its outermost face, which is the furthest from the capsule. Said plurality of weakening lines (2, 3) are located inside a circle whose radius is smaller than the inside radius of the flat collar so that they are not located in the area of the cap that joins the mentioned flat collar. The form of the weakening lines is an open form, for example, in U, in T in C, or any other, so that when broken by the pressure that is carried out by means of projections, properly arranged in the machine or in a tool designed for this purpose, do not separate from the layer by mixing with the ingredient or even appearing in the drink.

Preferably, at least one line of weakening (3) is arranged in the center of the lid and it is through which water is introduced to prepare the beverage, and several other lines of weakening (2) are arranged in a circle whose radius is smaller than the radius

inside the flat collar or may be arranged radially, where the greater radius of said radial weakening lines is smaller than the inner radius of the flat collar.

The weakening lines can be through (15), that is to say that they completely cross the layer, in this case two design options can be given, the first is that the material of the layer is elastic, in this first option, each of Through the weakening lines, there is a relief (7) projected towards the inside of the capsule in its entire perimeter, the interior surface of said relief is flat and perpendicular to the surface of the layer, this relief acts as a valve preventing the unwanted output of the ingredient. The second option, when the material is rigid, is that the ends of the weakening line are joined by another weakening line also passing through generating a plurality of through holes in the layer.

Other types of layers that can be incorporated into the lid are:

• First layers filled with filtering material (15) or

• Some filled second layers (8), which can be removably attached to the outer face of a layer that has weakening lines or through holes for closing until the time of using the capsule, in this case, the second filled layers are removably attached, for example by a suitable adhesive, and can consist of a circle (12) and a circular crown (13), said circle is removably attached to the layer that has lines of weakening, whose radius is greater than the radius of the circumference in which the weakening lines are arranged and smaller than the inner radius of the flat collar.

There are many arrangements of the layers that generate different types of caps for capsules, see figure 4 and 5, among which it is considered convenient to mention the following:

• A cover formed by two or more layers, each of the layers has weakening lines whose positions are coincident, it can be closed on its outer face by a full layer (8) adhesive.

• A cover formed by an upper layer that has weakening lines and a second layer filled with a thin material, for example, paper or aluminum, which breaks when the weakening lines break.

• A cover formed by a layer that has weakening lines and a lower layer, which can be heat welded to the flat collar, which has through holes.

All possible arrangements may incorporate a second layer filled with filter material.

In the event that the layer provided with through holes is integral with the capsule, the bottom base of the container may be removably attached to the walls of the container for filling.
