Description

This invention concerns an apparatus for producing a composition, such as a cosmetic product that can be consumed directly by an end consumer.

The document FR3026622 discloses a production apparatus for producing a composition, and more particularly, a cosmetic product, the production apparatus comprising a mixing machine configured to receive first and second capsules, containing first and second formulations, respectively, and to mix the first and second formulations directly in the first and second capsules so as to obtain the cosmetic product.

Such a production apparatus makes it possible for an end user to easily produce a personalized cosmetic product from different capsules. Such a production apparatus could also be used to produce other types of compositions, such as pharmaceutical products, plant-protection products, maintenance products, cleaning products or agrifood products.

However, the structure of the production apparatus described in the document FR3026622 could be simplified further. In addition, the production apparatus described in the document FR3026622 may prove to be complex for some consumers, in particular when it is necessary to connect the first and second capsules prior to their insertion in the mixing machine.

This invention aims to remedy all or a portion of these disadvantages.

The technical problem at the base of the invention consists of providing a composition production apparatus that is easy to use, with a simple and reliable structure.

For this purpose, this invention concerns a production apparatus for producing a composition, such as a composition that can be directly used by a user, the production apparatus comprising:

• • a receiving device configured to receive first and second capsules containing, respectively, a first formulation and a second formulation, the receiving device being configured to occupy an open position, in which the first and second capsules are able to be inserted into the receiving device, and a closed position, in which the receiving device is able to hold the first and second capsules in position, the receiving device being in addition configured such that moving the receiving device equipped with the first and second capsules from the open position to the closed position causes the first and second capsules to connect to one another, and
  • a mixing machine configured to receive the receiving device equipped with the first and second capsules, and to mix the first and second formulations contained in the first and second capsules so as to obtain the composition.

Such a configuration of the production apparatus, and in particular the fact that the receiving device is separated from the mixing machine, ensures that it is easy and simple for the end consumer to handle the production apparatus, since he only has to position the first and second capsules in the receiving device, and then place the latter in the mixing machine, which then mixes the first and second formulations in order to obtain the composition.

In addition, the fact that the first and second capsules are automatically connected by moving the receiving device into the closed position further simplifies the production of the composition for the consumer.

Furthermore, such a configuration of the production apparatus separates the function of positioning the first and second capsules from the function of mixing the contents of the latter, and thus substantially simplifies the production apparatus and makes it more reliable.
