The invention relates to a deformable single-use capsule comprising: a pocket (11, 41): containing a cosmetic product, the periphery (16, 46) of which is formed by two sheets (2 and 3, 5 and 6) plated and fixed one on the other, a channel (20, 50): connecting the pocket (11, 41) towards the outside of the capsule (1, 4), forming a narrowing of section relative to the pocket (1, 4), a frangible wall (13, 43): separating the pocket (11, 41) from the channel (20, 50), having the shape of a re-entrant angular sector (13, 43) inside the shape by elsewhere convex to the periphery (16, 46) of the pocket (11, 41), the rupture of which, caused by a pressure exerted on the pocket (11, 41), is effected by peeling, at the level of this re-entrant angular sector (13, 43), of these two sheets (2 and 3, 5 and 6) flattened and fixed one on the other, puts the pocket (11, 41) in communication with the channel (20, 50) so that the cosmetic product drains from the pocket (11 , 41) to the channel (20, 50), a connector (14, 44): male (44) or female (14), intended to couple with a connector, female (14) or male (44), d '' another capsule (1, 4), rigid enough to ensure a tight connection between the capsules (1, 4), once the connectors (14, 44) coupled together, located at one end (52) of the channel (50 ) opposite one end (51) of the channel (50) located on the side of the pocket (41) or else located at an opening (22) of the channel (20) distinct from the end (21) of the channel (20) located on the side of the pocket (11), opening outside the capsule (1). L'invention concerne une capsule déformable à usage unique comprenant : une poche (11, 41) : contenant un produit cosmétique, dont la périphérie (16, 46) est formée par deux feuilles (2 et 3, 5 et 6) plaquées et fixées l'une sur l'autre, un canal (20, 50) : reliant la poche (11, 41) vers l'extérieur de la capsule (1, 4), formant un rétrécissement de section par rapport à la poche (1, 4), une paroi frangible (13, 43) : séparant la
