Definitions

• the present invention relates to a process for packaging a product, in particular a solid cosmetic product, in the form of a sample.
• Patent FR 2 740 013 describes a packaging for a sample of solid or pasty cosmetic product intended to allow the distribution of the sample for advertising purposes by insertion in a publication.
• the packaging consists of a plate which has a central cavity into which is inserted a cup which contains the product sample.
• the cup is fixed by an adhesive sheet glued to one side of the plate.
• a seal is affixed to the other side of the plate in order to close off the cavity containing the cup.
• Such packaging even if it is in the form of a plate, is relatively thick due to the presence of the cup.
• the patent US Pat. No. 2,061,139 also describes packaging for a sample of cosmetic product in the form of a plate into which a cup containing the product is inserted. Again, it is difficult to obtain a thin packaging. It is therefore desirable to dispense with the cup and insert the product directly into the cavity. However, it is difficult to produce such a packaging which allows the product to hold correctly in the cavity and in which the external surface of the product, namely the surface visible when the packaging is opened, is acceptable from a point of view. aesthetic view, that is to say in particular which has a relatively regular surface.
• these objects are achieved by carrying out a process for packaging a product, in particular a cosmetic product, in a support of generally planar shape traversed by a cavity opening onto a first face of the support via a first opening, and onto a second face of the support, opposite the first, via a second opening, said method consisting in: a) removably close the first opening by means of a removable cover to be removed prior to the first use in order to access the product; b) introduce the product into the cavity via the second opening; c) close the second opening.
• the surface of the product which will be the external surface when the packaging is opened corresponds to the bottom of the cavity during filling.
• the bottom of the cavity being filled first, the external surface of the product delimited by said cover is perfectly smooth and the product is not likely to overflow the cavity on this side of the support.
• the product is introduced into the cavity in the form of a powder and then the said powder is compacted in the cavity before closing the second opening.
• an amount of product is introduced so as to at least fill the cavity so that no displacement of the product in the cavity is possible.
• the product is perfectly maintained in its packaging, in particular when it is opened by removing the cover.
• the excess product introduced is advantageously removed so as to only fill the cavity.
• the underside of the support remains perfectly flat and the thickness of the packaging is not increased.
• the second opening can thus easily be closed without any protuberance interfering with the closing.
• a constant volume of product is obtained in each packaging of this type, which in particular allows a user to know the quantity of product available when using a new packaging of the same type.
• the second opening is closed by means of an adhesive sheet which is fixed to the second face of the support.
• the adhesive sheet is fixed by pressing it with a roller so as to adhere, at least in part, the product to the adhesive sheet.
• the adhesive sheet is for example formed of a thermoplastic material, chosen in particular from polyolefins or polyesters, which is covered with a permanent adhesive composition, that is to say which is not intended to allow the peeling off the adhesive sheet.
• the adhesive composition fixes the sheet to the support and adheres in such a way that it is difficult to remove it from the support.
• the label can be decorated beforehand so as, in addition to its closing function, to decorate the packaging.
• the cover forming the means for opening the packaging, is bonded by means of an adhesive to the first face of the support in such a way that it can be peeled off and glued at least once.
• the user can open the packaging and use the product a first time, close the packaging if he has not used all the product, and remove the cover again to access the product again.
• the region of the cover intended to be in contact with the product has no adhesive function so as to avoid removing product which would remain on the cover when it is opened by the user.
• the cover is not coated with adhesive, for example, in this area.
• provision may be made to annihilate the function of the adhesive in this area by covering the adhesive with a varnish.
• provision can be made to leave in this zone the film constituting the back support of the adhesive seal.
• the cover has a gripping area making it possible to grip the cover in order to separate it, at least in part, from the support.
• the gripping area is for example an extension of the cover which, like the area of the cover intended to be in contact with the product, has no adhesive function.
• the cover is made of transparent material.
• the cover is for example a sheet of thermoplastic material, in particular polyester or polypropylene covered with a
• the invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to FIGS. 20 appended, among which:
• FIG. 2 shows a package obtained by the method according to the invention.
• the packaging process is described, according to the example, for packaging a solid cosmetic product.
• a rectangular support 20 of the bank card type has in its
• the support 20 has two planar and parallel faces 21 and 22 on each of which opens the cavity 31.
• the cavity 31 therefore has two openings 31 and 32 respectively on each face 21 and 22 of the support.
• the support 20 has a small thickness of the order of a millimeter, for example between 0.5 and 2 mm. According to a particular example, the support has a thickness of 0.8 mm.
• the support is for example obtained from molding or else cut.
• the cavity has a circular section but it can also be of square, rectangular, oval, or any other shape.
• the cavity is designed to receive a small amount of product, for example 0.15 g.
• a removable cover 40 is fixed 100 on one of the faces of the support, the upper face 21, so as to close one of the openings of the cavity, namely that through which the user can access the product.
• This is for example a glossy polyester type label which is glued to the upper face of the support.
• the label is covered with a semi-permanent adhesive allowing it to be kept correctly in contact with the face so as to close the opening while being easily removable from the face.
• an adhesive will be chosen which allows the label to be re-attached at least once to the support after a first opening.
• the back support for the label was kept during a specific cutting or weeding operation (double cutting for example), on two areas of the label 40.
• the back support is kept, on the one hand, in the zone 42 which comes into contact with the product so as to prevent the product from adhering to the label during opening and, on the other hand, in a gripping zone 41 situated at the periphery of the label so as to form a tab easily grasped by the user to remove the label from its support.
• the label has a smooth surface so that the upper surface of the product, that is to say the surface visible to the user when he opens the package, has a smooth appearance. But it is obvious that if one wishes to obtain a visible surface of the product which has another aspect, then one will choose a label with a suitable surface.
• the cosmetic product 10 is introduced 200 in powder form, through the second opening 32, into the cavity 30 closed in the lower part by the label 40.
• the powder introduced is then compacted 300 so as to form a product tablet which is then properly maintained in the packaging.
• the quantity of product introduced is preferably just sufficient to fill the cavity. When too much is introduced, the excess product is removed by suction after compaction. Alternatively, the product is introduced in liquid form.
• the second opening 32 is closed 400 by an adhesive film 50 by pressing it on the underside using a pressure roller 60 to evacuate the air and make the film adhere to the product.
• the adhesive film 50 forms the bottom of the packaging and participates in the holding of the tablet in the cavity.
