• the male connector 44 is completely hollow, a cosmetic product therefore being able to pass through it completely.
• the capsule 4 behaves similarly to the capsule 1.
• the operation of the mixer takes place with the two capsules 1 and 4 connected together by an autonomous machine actuating the pistons thereon, first by opening the frangible welds 13 and 43 to release their content initially present in the pockets 11 and 41, then to push this content towards the other capsule, and finally the mixture of one of the capsules 1 and 4 towards the other of these capsules 1 and 4, and vice versa alternatively.
• the opening force of the frangible welds 13 and 43 is controlled in order to be able to open fairly accurately and repeatably with reliability.
• these frangible welds 13 and 43 are designed to withstand a minimum safety pressure before they are used in the mixer.
• These frangible welds 13 and 43 are sealed so as to protect their contents from contamination or from an unwanted opening. Indeed, this can happen by an unexpected pressure during the handling during the manufacture of the capsule or during transport or during installation in the mixer.
