DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method of sealingly closing a case, particularly for cosmetic products, such as a make-up case, and also a corresponding improved case ensuring completely sealed closure.
In particular, make-up cases are known which are composed basically of a base and a lid articulated thereon which can be locked on the base.
The case receives a container on its base, the container being intended to contain a more or less volatile make-up product which may also deteriorate in contact with the ambient air.
The problem posed and which the invention aims to solve is that the lid does not ensure sealed closure to the air and to gas in cooperation with the case, so that the product contained in the case deteriorates, either as a result of the evaporation of its volatile components or, for example, as a result of oxidation by the air and/or humidification.
At present it is not known how to obtain sealed closure of a lid which is simply folded down onto the base of a case and which is held closed, for example, by a hook.
The method of the invention enables this problem to be solved by providing on the lid a means forming a substantially cylindrical skirt which can bear sealingly against an upper wall portion of the container, which contains the product, when the container is raised relative to the base, and by providing means for raising the container in the case when the lid has been closed on the base.
Advantageously, means are provided for first locking the lid on its base automatically in a first stage of operation of the case and then raising the container relative to the base in a second stage.
It will be appreciated that it is thus effectively possible to obtain a completely sealed closure owing to the cooperating bearing of the cylindrical skirt of the lid and the cooperating upper wall portion of the container when the container is raised against the lid.
The case according to the invention thus advantageously comprises: a generatrix directed substantially perpendicularly to the general plane of the lid, cylindrical complementary skirt which can cooperate with the skirt of the lid by coming into close contact therewith, of the case after the lid has been closed on the base of the case.
It will be appreciated that, with the means of the invention, it is relatively easy to obtain a closure which is completely sealed against gas and air between two substantially cylindrical cooperating complementary walls, also selecting in an appropriate manner the materials which will constitute those two walls, for example ABS (acrylonitrile butadiene styrene) for the case and polypropylene (PP) for the container.
Other features, aims and advantages of the present invention will be explained more clearly by means of the following description which is given with reference to the appended drawings showing a preferred embodiment by way of example.
In the drawings:
FIG. 1 is an exploded perspective diagrammatic view of a complete device forming a make-up case according to the invention.
FIGS. 2, 3 and 4 are diametral sectional views of the assembled device, these views being in a plane perpendicular to the axis of articulation of the lid on its base; FIG. 2 showing the case with the lid half-open, FIG. 3 showing the same case with the lid closed on the base, and the case not yet being locked sealingly, and FIG. 4 showing the position of the various components of the device after sealed locking of the case.
FIG. 5 is an enlarged view of the encircled detail V in FIG. 4.
With reference to the figures, in which the same reference numerals mark identical components, the following components, especially, can be seen: the case 1 formed by its base 2 on which the lid 3 is articulated about a hinge axis 4, a container 5 that is to contain the product accommodated in the case, a component 6 in the form of a ring which enables the container 5 to be raised and lowered as will be explained in detail hereinafter, a component 7 forming an ornamental plate hiding the operating mechanism of the device, and a mirror 8 adhe
