Method for Packaging a Beverage Powder in a Beverage Capsule

摘要

A method for packaging in a capsule a beverage powder tending to evolve a gas, said capsule comprising a capsule body (103) defining a cavity (106) containing a quantity of beverage powder, said cavity being hermetically sealed up comprises the following steps:
providing a quantity of said beverage powder evolving a gas within said cavity (106) of said capsule body (103);applying a vacuum into said cavity (106) of the capsule body (103), so that the internal pressure in the cavity (106) is below atmospheric pressure;sealing the capsule to hermetically close said cavity (106), while maintaining the internal pressure in the cavity (106), below atmospheric pressure; andkeeping said gas emanating into the cavity (106) of the capsule so that the internal pressure in the sealed-up capsule is above atmospheric pressure.;Use for packaging in a capsule a ground coffee.

1. A method for packaging in a capsule a beverage powder tending to evolve a gas, said capsule comprising a capsule body defining a cavity containing a quantity of beverage powder, said cavity being hermetically sealed up or respectively, the capsule being hermetically sealed up by an over-packaging, the method comprising the steps of:
providing a quantity of said beverage powder evolving a gas within said cavity of said capsule body; applying a vacuum into said cavity of the capsule body, or respectively, into said over-packaging containing the capsule, so that the internal pressure in the cavity, or respectively, in said over-packaging is below atmospheric pressure; sealing the capsule to hermetically close said cavity, or respectively, sealing the over-packaging to hermetically close the over-packaging surrounding the capsule while maintaining the internal pressure in the cavity, or respectively, in said over-packaging below atmospheric pressure; and keeping said gas emanating into the hermetically closed cavity of the capsule so that the internal pressure in the sealed-up capsule, or respectively, in said over-packaging, is above atmospheric pressure.
