A recently granted patent (Publication Number: US11772060B2) describes a device for preparing a cosmetic composition. The device includes a housing with a movable piston and an outlet nozzle. What sets this device apart is that it can accommodate multiple capsules, each containing a constituent of the cosmetic composition. The piston is designed to perforate each capsule in succession and convey the contents to the outlet nozzle.

The patent also mentions that the device can have multiple piston heads with different outer diameters, arranged in increasing order of diameter along the housing. Each piston head, except for the smallest one, has a conduit that opens onto two opposite faces of the head. These conduits can snap-lock with the preceding head to create a seal.

The capsules themselves have a cylindrical side wall with an inner conduit and two seals at opposite ends. The patent suggests that the capsules can have different outer diameters, with the second diameter being larger than the first. The device may also include means for reducing the inner diameter of the housing or increasing the outer diameter of the first capsules, such as lateral fins on the capsule's side wall.

Additionally, the patent mentions the inclusion of a heating device to independently heat the contents of each capsule in the housing. The receptacle for the cosmetic composition can be a folded flexible bag tightly mounted on the outlet nozzle.

The patent also describes a process for preparing the cosmetic composition using the device. The capsules are positioned in the housing, and a receptacle or preform is connected to the outlet nozzle. The piston is then moved to perforate the capsules and convey their contents into the receptacle. The process can include heating the contents of each capsule before moving the piston and tightly positioning a folded bag on the outlet nozzle to collect the composition.

After obtaining the cosmetic composition, the receptacle can be detached, and the perforated capsules can be removed from the housing. A new receptacle or preform can be positioned, and a new set of capsules containing a different cosmetic composition can be introduced into the housing.

Overall, this patent presents a device and process for efficiently preparing cosmetic compositions by sequentially perforating capsules and collecting their contents. The inclusion of multiple piston heads, heating capabilities, and the ability to replace capsules and receptacles make this device versatile and potentially useful in the cosmetic industry.
