Description

Packaging, application, and/or dispensing devices The present invention relates to a device for packaging, applying, and/or dispensing a product, particularly a cosmetic product, and more specifically, to a device capable of refilling the product. In general, design and development processes that present ecologically responsible and environmentally friendly solutions have become a key concern in addressing global challenges. Reducing a product's carbon footprint requires essential elements in product design, such as reducing the amount of materials used, replacing them with more eco-friendly materials, or using recyclable materials. It is important to develop packaging optimized for the product volume. To achieve this, it is necessary to redesign or adjust the size of the packaging to reduce the amount of material in terms of volume and weight. The goal is to reduce the carbon footprint of packaging by proposing reusable and environmentally responsible containers, particularly those that can be refilled at home or in stores. To reduce manufacturing costs and minimize environmental impact of cosmetic packaging materials, devices used for packaging, applying, and/or dispensing products—particularly refill products and devices containing cases for refills—have been developed. In this approach, issues arise regarding how to configure the device to allow for the replacement of refill products, and specifically how to configure the device to ensure that the refill is safely stored within the case in use, depending on the type of product contained in the refill. There is a growing need to gradually replace existing packaging materials with packaging and application/or dispensing devices that allow for cosmetic refills. This allows users to leave the case intact and discard only the refill after the cosmetic product is used up. When the refill runs out, users simply need to remove it and replace it with a new one or a different refill. In this context, packaging, application, and/or dispensing devices must possess the aesthetic quality required by the user, be as easy and efficient to use as refillless devices, and be designed so that the task of replacing used refills is as simple as possible for the user—that is, requiring minimal effort or attention. Therefore, the packaging device must ensure that the refill contents are stably stored inside the case during use. Various forms of this type of device have already been proposed. Pipette packaging and dispensing devices are known, in particular in Utility Model CN214931380U and International Application WO9947262A1, which include a ring that secures a refill to a case. After inserting the refill, the ring is secured to the case by screwing or snapping, adhering closely to the edge of the refill to prevent it from falling out. Removing the refill requires several steps and operations, making replacement cumbersome. In particular, as disclosed in patent application FR3126287A1, a packaging and dispensing device is known that has a system for securing a refill container in place inside a case, which is configured to prevent the refill container from coming out of the case by its own weight through friction with the outer wall of the refill container. This system is described in particular in relation to a pump dispensing device capable of dispensing a product using pressure without rotating the device. This type of system fails to effectively and consistently secure the refill container within the case, especially when the refill container is attached to the case and features a screw-on cap connected to the main body. If rotational force (torque) generated during the process of manipulating the refill or cap to dispense or apply the product is transmitted between the refill and the case, it can interfere with efficient operation, such as causing the refill to detach or opening the cap. For example, when attempting to twist the cap open, the refill container may rotate along with the cap. This can make it difficult to use the refill mounted in the case and hinder smooth opening. As a solution to these drawbacks, there may be a method to increase the rotational resistance (resistance torque) generated at the contact point between the friction member and the refill by increasing the interference between the friction member and the refill. However, this increase in interference has the side effect of reducing convenience when inserting the refill into the case axially or separating it from the case, and consequently makes this operation process cumbersome and difficult for the user. Therefore, there is a need for cosmetic refill-equipped packaging and application and/or dispensing devices that remain attractive to consumers while encouraging the reuse of existing cases instead of discarding them for new refills. In addition, there is a need to improve product refill packaging and application and/or dispensing devices. To this end, the usability of these devices should be
