FR2565559A1 - Receptacle with airtight closure for cosmetic products - Google Patents

Abstract

Receptacle products which must be preserved protected from air, which comprises a container 1 and a sealing member 2 for the airtight closure of the container opening, characterised in that it is equipped, in addition, with a lid 3 the edge of which is fixed to the lateral wall 1' of the container by elastic locking means 7-8. Stopping means are provided between the internal wall of the lid 3 and the external wall of the body 1 of the container, in order to determine the angular position of the lid in relation to the body exactly.

Description

 The invention relates to a container with a tight closure, in particular a jar or bottle which is particularly suitable for packaging cosmetic, pharmaceutical or food products and, in general, products which must be stored away from the ambient atmosphere. .

The invention relates more specifically to a three-piece container, the outer surface of which can receive inscriptions, drawings or other signs, which go well with the body of the container and its lid.

 In current practice, when a product must be stored in a leaktight manner, a container is used whose lid or plug is screwed into or onto the main body intended to contain the product; most often a seal is interposed between the cover and the edge of the opening of the body, to allow good closure by screwing tightening the seal. But then, if one wants to have inscriptions, drawings or other impressions, both on the side wall of the lid and that of the body of the container, special measures must be taken to bring them into line with one another, by alignment At the time of printing, which is currently done very frequently by serography, precise identification is then necessary, in order to avoid discrepancies between the part of the text and of the drawing carried on the cover and that which in fact the continuation on the body of the container. However, even at the cost of this complication, in the long run the two inscriptions or drawings cease to be properly aligned, due to the crushing of the seal and / or the deformation of the thread which - like the container itself - is made at the present time generally out of plastic material. When the lid fits onto the container by pressure, that is to say by elastic engagement constituting a stapling or clip, the situation of the inscriptions is even worse, because the two parts, lid and container, are then free in rotation with respect to each other. There can therefore be no question of providing the two surfaces with some homogeneous text or design between these two parts; at any time, the rotation of the cover would shift them making them incomprehensible.

 It can thus be seen that the known means for closing containers do not make it possible to obtain inscriptions or drawings thereon, of which those of the container would be a homogeneous series, and not offset from those of the lid.

And yet, for technical or / and aesthetic reasons, it may be necessary to print on the entire outer surface of a container indications, recommendations, distinctive signs or other, readable at any time without any discomfort, from that the lid has been put on the container of the container.

 It is this gap in the prior art that the present invention makes it possible to fill with new means, in a very practical manner. It produces a container, easy to produce in molded plastic, the container of which can be closed with good sealing, while being capped by a cover which is easy to put on and take off, but which does not rotate.

 The container according to the invention consists of three essential parts: a body or container intended to receive the product to be preserved, a screw-on or force-fitting stopper in or on the opening of the container, and a cover adapting by elastic engagement or clip on this opening of the container, without possibility of rotation.

An important characteristic of the invention resides in that stop means are provided in the contact zone between the inner wall of the lid and the periphery of the container of the container, so that the elements of the clip are immobilized in rotation, when the cover is snapped onto the body of the container. These stops can in particular be formed by projections on the
inner wall of the cover, intended to slide in
corresponding hollows in the periphery of the body, or
vice versa.

According to a preferred feature of the invention, the é
clip elements on the periphery of the container are found
facing or near the edge of the wall opening of the
container. Since this region has both
a clip and a thread or nozzle fitting, all
both plastic, holding the cover by the clip
is improved due to stiffening produced by the
presence of the plug in the opening of the container.

In particular, it is preferable that the bottom of the
clip used is only at a distance of 5 to 30 mm,
or better from 8 to 20 mm from the edge of the container opening,
it being understood that the threading or the nozzle begins practi
only on this edge.

In the preferred form of the invention, the wall la
container, just like the lid, is cy
lindrique; it continues continuously on the wall of the neck
circle, the whole presenting itself as one and the same cy
lindre. To achieve this external uniformity between the
side walls of both sides, some withdrawal from the
container wall is made at the level of the part which
receives the cover.

The bottom of the container is flat, concave or conform
mé with hollows or bosses so that it can be
adapt on plinths or other bases.

The top wall of the cover is flat, con
cellar or convex; its position, that is to say the height of the cover, is sized according to the use that is to be made
re of the interior space, between this upper wall
and the container cap. It is planned, in fact,
before the invention, the application of this space as a room
ment for a notice on the product concerned or / and for
accessories for using the product, such as pads, brush, towels, syringe, vial or ampoule of diluent or other adjuvant of the product from the container, etc. For this, the height of the space between the upper wall of the cover and the stopper generally represents 5 to 50% of the total height of the container, and preferably 20 to 40%.

 With regard to the relative dimensions of the container, the diameter / height ratio can vary widely and, preferably, between 0.8 and 2.5, especially between 1 and 2.

 By way of nonlimiting examples, some of the embodiments of the container according to the invention are described below.

 Figure 1 shows the three parts that make up the container according to the invention: the body 1 of the container including 11 interior space is designated by 5, the cap or shutter 2 of this container and the cover 3 covering the whole. The container thus has two closures, one sealed, 2, and the second non-sealed, 3.

 The sealed closure is obtained in the manner known per se, by screwing the plug 2 in or on the opening of the body 1 on a thread 2 ', or else by forcing this plug into the opening along smooth surfaces. nozzle 2 '. Although the drawing represents the case where the plug penetrates somewhat into the opening of the container, it is also possible to use a shutter fitting on the edge 1 ′ of the opening, the nozzle or threaded surface then being on the outside caté of this edge.

 The cover 3 is fixed to the body 1 by an elastic interlocking system or clip comprising a bead 7 on the outer wall of the body 1 of the container and a bead 8 on the inner wall of the cover 3. The detail of this arrangement is shown in section in FIG. 2 which is an enlargement of the corresponding part, surrounded by a circle, in FIG. 1.

 According to a particular characteristic of the invention, one or more stops are provided on the periphery of the edge 1 ′, on the body 1, and on that, inside, of the cover 3, so that once engaged, the beads 7 and 8 cannot slide relative to each other. The shape, number and special arrangement of these stops may vary, provided that they are located on the periphery of the body 1, between the end edge of the container opening and the end edge of the lid, when the latter is engaged on the body 1, and that they force the cover 3 to take one or more precisely determined angular positions relative to the body 1.

 In FIG. 3A an embodiment can be seen, in which the stop is constituted by a lug 11 intended to enter into a groove 10 in the part 1 ′ of the body 1, visible in FIG. 3B, parallel to the axis of the body. To place the cover, it suffices to cover the wall 1 'of the container, then turn along arrow 12, until the lug 11 enters the groove 10; by pressing in the direction of arrow 13, the bead 8 is made to engage under the bead 7. The clip, thus formed, does not allow the cover 3 to rotate, since the lug 11 and the groove 10 use stops mutually.

 As a consequence, the inscriptions or drawings 4-4 ′, on the external faces of the container and of the cover, shown diagrammatically in FIG. 1, always remain perfectly aligned.

 In the variant of FIGS. 4A and 4B, the lug 11 and the groove 10 are V-shaped, which facilitates closing, the position in which the clip is engaged thus being easier to find.

 it should be noted that for these two forms of execution, fig. 3 and 4, the lug 11 must have a thickness h sufficient to not risk crossing the bead 7 elsewhere than at the location of the groove 10; this is shown in Figure 3A.

 Although FIG. 3A represents a single bead 8, it is understood that there may be several extending over a greater or lesser fraction, or over almost all, of the periphery of the parts in question. Similarly, with regard to the stops, that is to say the pins and corresponding grooves, it may be advantageous to provide several, for example distributed symmetrically on the periphery of the body 1 and of the cover 3, when the inscriptions aligned on the body and the cover have the same symmetry.

 Figures 5A and 5B illustrate the case where, unlike the previous embodiments, the lug (s) 15 are on the outer wall of the container, instead of being provided on the inner face of the cover; conversely, the groove 14 here constitutes a discontinuity between two beads 8 on the inner surface of the cover 3. The engagement mode is the same as with the provisions of FIGS. 3 and 4. FIG. 5A relates to the case where the wall 3 is too thin to carry a groove.

However, as the seal at 5 is ensured by the plug 2, it is possible to have in the wall of the cover 3, a groove 14, or lumen, completely passing through this wall.

 As mentioned above, the part 1 ′ of the body 1 of the container, between the base of the clip 7-8 and the edge of the opening 2 ′, preferably has a height of the order of 5 to 30 mm, heights from 8 to 20 mm being particularly indicated when the cover is made of relatively thin plastic material.

 The container may be made of any suitable material, in particular of metal or plastic, provided that the wall of the cover 3 has sufficient elasticity to allow the clip to be engaged, which comprises an elastic deformation designated by 9 in FIG. 2.

 The free space 6, between the plug 2 and the ceiling of the cover 3, is that which it is said above that it preferably has a height of the order of 5 to 50% of the total height of the container. . it is used to house notices or / and various accessories or additives for the product contained in 5.

 In a particular embodiment, the shutter 2 is constituted by a sheet glued or welded to the edges of the container 1; this sheet is removed or discarded by the user when the latter starts the product from the container.
