A fluid transfer assembly comprises a housing for accommodating a fluid. A bellows member disposed in the housing defines an opening therethrough adapted to be in fluid communication with an applicator assembly. The bellows member is adapted to operatively engage the applicator assembly for extension in a first direction and contraction in a second direction. The bellows member seals against the inner surface of the housing during extension and contraction for defining a variable volume chamber with the housing. Expansion of the bellows member in the first direction reduces the chamber volume for generating positive pressure in the housing and forcing fluid through a valve to the applicator assembly. Contraction of the bellows member in the second direction increases the chamber volume for generating negative pressure within the housing for drawing fluid into the chamber.

A packaging and distribution device, for example a device for treatment with an electric current, includes: a refill containing a product to be distributed, including a vessel defined at least partially by a flexible wall; a pressing member for pressing on the flexible wall in order to apply pressure to the product contained therein, wherein the pressing member includes two flaps hingedly connected to one another, each connected to a mechanical system biasing the flap to bear against the refill.

Applicator for applying a cosmetic product to the skin, in particular the eyelids, comprising an applicator member (10), the latter having on its external surface a recess (12) and an applicator tip (15) having a substantially flat main facet (20) extending from the recess (12) towards the distal end of the applicator member (10).

A refillable bottle (10) is provided, comprising a lid (1) that can be connected to an applicator (2) and a storage portion (3) that can be connected to the applicator (2), in which the lid (1), the applicator (2) and the storage portion (3) are connected together using screw threads in the lid (1), the applicator (2) and the storage portion (3). An accompanying method for refilling a bottle (10) is also provided, comprising the following steps: disconnecting the storage portion (3) from the applicator (2) by means of a first unscrewing action, and connecting a refill (20) to the applicator (2), in which the force required to perform the first unscrewing action is greater than the force required to perform a second unscrewing action, the second unscrewing action being understood to be the action performed to disconnect the lid (1) from the applicator (2).

An applicator device or dispenser includes a stone applicator tip and a housing which may, in some examples, have a reservoir for containing a product, such as a cosmetics product or a medicinal product. The stone tip comprises a material that is capable of storing and retaining and/or transferring thermal energy during application of the product.

According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

A fluid dispenser device including an outlet, a pocket having an interior volume for containing a fluid, the interior volume being delimited at least in part by a movable wall, a reservoir arranged to contain the fluid, a pocket cap, a cavity, a reservoir orifice joining the reservoir and the cavity; wherein the pocket cap is arranged to be mounted by insertion in the cavity of the device so as to be mounted by extending: by passing through the pocket at least partially while passing through the movable wall orby going along the pocket at least partially, the device comprising an inlet orifice arranged to insert the pocket cap into the device from the outside of the device and opening into the cavity.

According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

Systems, devices, and methods including a container including: a base portion configured to receive a dampened cosmetic sponge; a cap portion configured to be detachably attached to the base portion; and one or more apertures disposed in the cap portion, where the one or more apertures provide airflow into the container.

Disclosed is a versatile dispenser suitable for a broad spectrum of product consistencies common in the cosmetics and personal hygiene industry. The design of the dispenser incorporates various mechanisms that allow the user to control product dispensation effectively and economically. These include a roller engagement mechanism and a force exerting element, operationally connected to a movable platform, enhancing the user's control over product application. In addition, the container is designed to accommodate both direct filling and use of reusable/refillable or environmentally friendly disposable cartridges, offering ease of cleaning, quick product switches, and promoting sustainability. Furthermore, the dispenser can be enhanced with heating or motorized mechanisms for specific product requirements. The modularity and versatile design cater to a wide array of product types, demonstrating the dispenser's adaptability and potential use across different areas of the cosmetics, personal hygiene, and other suitable industries.
