Benefits of technology
"The present invention provides a disposable capsule for beverages and foodstuff which is simple and cost-effective to manufacture and use. The capsule has a sealed film that can be opened exclusively when used, allowing for the beverage or food product to be dispensed without the need for additional parts or changing the external dimensions of the capsule. The capsule also has perforation means that allow for the film to be opened without causing any particles to be released during the opening process. The capsule can be used with different machines for the preparation of coffee or beverages, and can be adapted to different amounts of product to be encapsulated. The invention also provides a method for opening the capsule and a disposable capsule for the preparation of different beverages."
Problems solved by technology
This solution is not suitable for the use with automatic beverage dispensing machines.
In fact, once the capsules are removed from their hermetic package and loaded in the automatic machine, they are no longer sealed and the product (for instance ground coffee) might deteriorate as above described.
Breaking of the container walls, or their perforation, may cause the release of particles of the same capsule that fall inside the container, mixing with the food product.
As a consequence, the dispensed beverage may also be disagreeable and have a poorly appetizing aspect, or worst, may contain extraneous parts.
In this embodiment means for the capsule opening are provided on the beverage dispensing machine, having the disadvantage of contacting the beverage, with resulting cross-contamination problems when capsules for different beverages are utilized.
The drawback of such embodiment is that it requires the presence of a movable element, with resulting production and assembling costs.

Embodiment Construction
[0056]FIG. 1 shows a capsule C according to the invention, comprising a container 1, an upper wall 2 suitable to close the container 1 and a film 4. The upper wall 2 together with the film 4 hermetically close the assembled capsule C. For instance, the wall 2 may be welded to the container 1 through ultrasound welding. The film 4 is fixed, for example is thermo-welded, to the container 1 coupled to the wall 2, for example by thermo-welding the film 4 on a peripheral circular area of the wall 2. The capsule C may contain different food products 3. For example the capsule C of FIGS. 1 and 2-2C is suitable for the preparation of beverages from fresh ground products, e.g. coffee or the like, while the capsule shown in the FIGS. 3A-3C can be used for the preparation of beverages from soluble products.
[0057]In the embodiment shown in FIG. 1 the encapsulated product is coffee powder 3, compressed in the container 1 to a predefined compactness grade, known in the art. The film 4 is coupled ...

A capsule (1) for the preparation of beverages within dispensing machines, has a sealing film (4) which is perforated at the time of the use when the pressurized infusion water is supplied to the capsule and deforms the film (4), bringing it into contact with underlying perforation means (6) fixed to the same capsule.
Description
BACKGROUND OF THE INVENTION[0001]The present invention concerns a disposable capsule containing for example powder or ground products intended for the preparation of beverages such as coffee, tea or the like in dispensing machines. The invention also concerns a method for opening said capsule.[0002]For the sake of clarity, in the following description reference will be explicitly made to the specific manufacturing of containers shaped as disposable capsules for the preparation of beverages, being understood that the principles of the present invention may be applied to any type of sealed containers for foodstuff which has to be opened in order to release its contents, or to allow the mixing with other products or substances, before or during the evacuation of the contents from the same container.DESCRIPTION OF THE KNOWN ART[0003]For instance, the European patent application EP 1440910 concerns a disposable capsule for the preparation of beverages starting from a food product contain...
