Definitions
- Packaging for packaging a product such as a cosmetic composition
- the invention relates to the packaging of products, such as cosmetic compositions. More specifically, the invention relates to a packaging for packaging a product, such as a cosmetic composition, comprising a container provided with an opening and delimiting a housing, a lid movable between a closed position in which it closes the door. opening the container and an open position, and a storage unit.
- a packaging for packaging a product such as a cosmetic composition
- Such packages also called “containers” are used mainly for the packaging of products containing volatile components, in particular for cosmetic, pharmaceutical and similar compositions.
- the products concerned must be able to be kept under optimum sealing conditions in order to prevent the air present in the packaging, which is loaded with product moisture, from escaping and being replaced by middle air. ambient outside drier. If there is a leak, this exchange would result in a rebalancing of the hydrometry of the product and therefore a weight loss of the product over time.
- Packaging of the aforementioned type is already known, the lid of which is either screwed onto the container or hinged to the latter by a hinge.
- the seal is generally provided by seals exerting efforts in the radial direction, which often requires a large screwing torque in the case of a screwed lid or a large closing force in the case of a hinged lid. The handling of these packages is therefore not comfortable for a user as well for closing as for opening the lid.
- the invention aims in particular to provide a package of the aforementioned type which provides a comfortable opening and closing of the lid in conditions satisfactory to the user.
- the invention proposes for this purpose a packaging of a product, as defined above.
- the storage unit comprises a tank housed at least partly in the housing of the container and defining a reservoir adapted to receive the product, said vessel being movable in a vertical axial direction between a rest position, a high position and a low position, and an elastically deformable pressure difference compensation system adapted to form a sealed connection between the tank and the lid.
- the storage unit delimits, in combination with the lid in the closed position and for a constant amount of cosmetic product, a sealed compartment having a first volume when the tank is in the rest position, a second volume lower than the first volume when the tank is in the high position and a third volume greater than the first volume when the tank is in the low position.
- the deformable nature of the pressure difference compensation system allows the vessel to move according to the differences between the pressures prevailing on either side of the compartment, and therefore to increase or decrease the volume of said compartment while the same amount of cosmetic product is contained in the tank at a time t, while maintaining the tight separation between the outside and the inside of the compartment.
- the displacement of the tank makes it possible to satisfy the Boyle-Mariotte law that the product of the pressure and the volume of a perfect gas at constant temperature is, in the chamber forming a sealed enclosure, constant.
- a flexible connection is thus obtained which makes it possible to vary the volume of the compartment, reducing the pressure exerted on the sealing zone.
- the packaging according to the invention is particularly compact, simple design allowing a reduced number of parts and inexpensive.
- the term "packaging” means different types of packaging or containers, such as bottles, jars, tubes, boxes.
- the package comprises a flat bottom to which is attached a cylindrical wall having a selected geometric contour, for example circular, oval, elliptical, polygonal, etc.
- Such a package is open at the top to form the opening that receives the lid.
- the tank of the storage unit in the closed position of the lid, is in the rest position when the pressure inside the compartment is equal to the pressure outside the package, in a high position when the pressure inside the compartment is greater than the pressure outside the package, and in a low position when the pressure inside the compartment is lower than the pressure outside of the packaging.
- the packaging further comprises at least one spring means bearing on the container and biasing the pressure difference compensation system in a vertical axial direction so that the difference compensation system of the pressure comes into sealing engagement against the lid when said lid is in the closed position.
- the at least one spring means of the packaging of the invention ensures a constant and reliable pressure on the pressure difference compensation system forming the sealing zone between the container and the lid. This spring means is thus able to absorb the deformations and to oppose the internal pressure in the compartment.
- this at least one spring means comprises an at least partially corrugated spring acting in compression and arranged perpendicularly to the vertical axial direction.
- This spring can be made of metal or plastic.
- the pressure difference compensation system comprises a generally flexible peripheral ring surrounded by a generally rigid annular edge.
- the pressure compensation system is preferably formed by overmolding two materials comprising a first generally flexible material for the peripheral ring and a second generally rigid material for the annular border.
- the peripheral ring comprises a seal sealingly against the lid.
- the peripheral ring comprises a deformable membrane, said membrane comprising an outer periphery integral with the annular rim and an inner periphery integral with the vessel.
- the deformable membrane is carried by the storage unit.
- the cover when the cover comes into the closed position, the cover ensures the displacement of the annular edge towards the bottom of the housing ensuring the compression of the spring means to help achieve sealing. Conversely, when the lid is then brought into an open position, the spring means tends to facilitate opening by moving the annular border upwards.
- the housing of the container communicates with the outside through at least one vent arranged through the container. This contributes to putting the housing to the external pressure, that is to say to the atmospheric pressure.
- the lid of the invention may be completely independent of the container. However, it is preferred that this lid is connected to the container by a hinge. Thus, the lid can not be lost.
- the hinge may comprise a first hinge portion secured to a ring attached to the container and a second hinge portion integral with the lid.
- the storage unit is provided with a removable cap adapted to close the tank.

- the volume of the compartment 8 varies according to the position of the tank 21. More particularly, the tank 20, delimited by the bottom wall 21a, the side wall 21b and the opening 21c of the tank 21, has a constant volume and the first zone 38, delimited by the central zone 33 of the insert 32, the sealed connection and the opening 21c of the tank 21, has a variable volume.
- the tank 21 When the internal pressure P1 inside the compartment 8 is equal to the external pressure P2 outside the package 100, the tank 21 is in the rest position, as can be seen in FIG. 1, and the compartment 8 presents a first volume V1.
- the tank 21 When the internal pressure P1 inside the compartment 8 is less than the external pressure P2 outside the package 100, the tank 21 is in the raised position, as can be seen in FIG. 2, and the compartment 8 presents a second volume V2.
- the second volume V2 is smaller than the first volume V1 in order to satisfy Boyle-Mariotte's law. As a result, the moment when a leak occurs at the seal 28 is pushed back by the displacement of the tank 21.
- the tank 21 When the internal pressure P1 inside the compartment 8 is greater than the external pressure P2 outside the package 100, for example when the package 100 is placed in the hold of an aircraft in flight, the tank 21 is in the low position, as shown in Figure 3, and the compartment 8 has a third volume V3.
- the third volume V3 is greater than the first volume V1 and the second volume V2 in order to to satisfy Boyle-Mariotte's law. As a result, the moment when a leak occurs at the seal 28 is pushed back by the displacement of the tank 21.
- the manufacture of the package 100 and more particularly the packaging of the product in said packaging 100 is carried out in factories in which there is a factory atmospheric pressure.
- the atmospheric pressure is, for example, close to the atmospheric pressure at sea level.
- the internal pressure P1 inside the compartment 8 of each of the packages 100 is equal to the factory atmospheric pressure.
- Packaging 100 and packaged are then sent to storage centers before being individually sold to users. An interval of several weeks to several months may exist between the packaging of a package 100 at the factory and its opening for the first time by the user. It is generally in this interval of time that the tightness of the package 100 is the most heavily solicited (transport in the hold of aircraft, frequency of variation of atmospheric conditions related to the alternation of anticyclones and depressions, etc. .).
- the storage unit 2 When the lid 3 is in the open position, the connection between the lid 3 and the storage unit 2 is broken and the internal pressure P1 is equal to the external pressure P2, the tank 21 is in the rest position.
- the storage unit 2 has a pleasant visual appearance for the user, requiring no additional room masking the pressure difference compensation system 22.
- the invention finds particular application to the sealed packaging of products containing volatile substances, such as cosmetic creams or pharmaceuticals, this list is not limiting.
