Machines for using capsules for obtaining infusions such as espresso or beverages from water soluble products

Abstract

A machine for using capsules for obtaining infusions, such as espresso, or beverages from water-soluble products, wherein the capsules are of the type comprising an internal out flow duct comprising an internal through hole for the outflow of the infusions or beverages from the capsule and an upper surface supporting a sealing element, the machine comprising housing means for housing at least one capsule during the dispensing phase and injection means for injecting water under pressure into the capsule so as to obtain an infusion or beverage flowing out from the capsule through the internal through hole of the capsule, wherein the injection means are adapted to inject water into the capsule through the sidewall of the capsule.

Description

RELATED APPLICATIONS[0001]This application is a divisional of U.S. application Ser. No. 13 / 320,703 filed Jan. 4, 2012, which is the National Stage of International Application No. PCT / IB2011 / 001343 filed Apr. 8, 2011, which claims the benefit of Italian Application No. BO 2010A000216 filed Apr. 9, 2010, all of which are herein incorporated by reference.FIELD OF THE INVENTION[0002]The present invention relates to the technical field of injection moulded or thermoformed capsules, hermetically sealed and filled with infusion products, such as espresso coffee, and / or with water-soluble products, such as powdered milk or cocoa, and of the corresponding machines using same.BACKGROUND OF THE INVENTION[0003]Some kinds of injection moulded capsules comprising an internal out flow duct and filled with infusion products, such as espresso, or with water-soluble products, are known in the art.

AI Technical Summary

Benefits of technology

The solution allows for high-quality, cost-effective production and preservation of infusion products, preventing accidental loss and maintaining organoleptic properties, while adjusting pressure for varying beverage intensities.

Problems solved by technology

Some of the known capsules are cumbersome, expensive and difficult to produce because they are complex and very detailed which slows down their production.

Consequently, the quality of the product contained in the capsules deteriorates in the course of time.

Furthermore, the product can accidentally come out of the capsule, thus lowering the quantity of product contained in the capsule and contaminating the environment wherein the capsule is handled and / or stored.
