## Background
FIELD OF THE INVENTION
The invention relates to a container made of a material which is transparent to light, and is intended to contain a product, particularly a transparent product such as a transparent liquid; the container having in at least one wall, a reserve or recess into which is fixed a hollow sealed insert which itself contains a fluid and in which particles, such as plastic beads, can move, possibly past a decoration.
BACKGROUND OF THE INVENTION
Containers of the type described above are known, but have as a major disadvantage that the fitting of the insert into the reserve or recess is detrimental to the aesthetic quality of the receptacle, something which is incompatible with containers particularly of luxury goods.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a container which alleviates the above described disadvantage of the prior art.
To achieve this objective, the container according to the invention is characterized in that: (1) the insert comprises a body in the form of a dish intended to hold the fluid and a blanking or sealing plate provided on the front face of the body extending beyond edge(s) of the front face, thereby forming an annular part surrounding the edge(s) of the body; (2) the reserve has a complementary shape to the insert; and (3) the rear face of the annular part constitutes the zone by which the insert is fixed by bonding into the reserve.
According to one embodiment of the invention, the reserve comprises, in its depth direction, a stepped profile comprising an annular part of shallow depth roughly equal to the thickness and shape of the annular part of the insert, and a deeper central part for accommodating the dish-shaped body.
According to another embodiment of the invention, the rear face of the annular part of the insert and/or the complementary face of the annular part of the reserve is opacified so as to prevent the adhesive from being visible.
According to another embodiment of the invention, the wall of the reserve is flat and the lateral faces of the annular part and of the central part are inclined with respect to the normal direction by a predetermined angle, the reserve widening toward the exterior face of the wall.
According to yet another embodiment of the invention, the reserve has a circular shape.
According to another embodiment of the invention, the annular part and the central part of the reserve, have a constant depth.
According to another embodiment of the invention, and especially when all or at least part of, the reserve and/or the insert are completely transparent, the inside end of the reserve and/or the end wall of the insert have/has a raised pattern which forms at least part of the aforesaid decoration.
The invention will be better understood and other objects, features, details and advantages thereof will become apparent in the explanatory description which follows with reference to the attached schematic drawings given solely by way of example illustrating one embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION
The invention is described hereinafter in its application to a container 1 in the form of a bottle. As shown by FIGS. 1 to 3, this bottle has, in the view from above or from underneath, a roughly rectangular profile. The corners of the profile are rounded. This bottle comprises, in at least one of its long side walls, namely in wall 3, an insert 4 engaged in a reserve 5 formed as a circular recess made in this wall 3. This recess has, in the direction of its depth (into the wall), a stepped profile which is clearly visible in FIG. 4. The recess comprises an outer annular part 6 of a depth a and a central part 7 of a total depth b. The inside end 8 of the recess is flat and runs parallel to the exterior face of the wall 3 of the container 1. The lateral faces 9 of the annular part 6 of the recess and the lateral faces 10 of the central part 7 are inclined at predetermined angles α and β, respectively, relative to the direction which is perpendicular (normal) to the face of the wall 3, such that the two parts widen toward the exterior face of the wall 3.
Referring to FIGS. 5 and 6 it may be seen that the insert 4 has a shape that complements that of the reserve 5 and is made in the form of a hollow body 13 in a material transparent to light, such as plastic, which is intended to contain a fluid, such as a liquid, and a transparent sealing or blanking plate 15 for closing off this hollow body.
The sealing plate 15 is fixed to the annular front rim of the dish-shaped body 13 and extends radially, beyond this rim forming an annular part 16 around the body.
The outside and inside diameters of the annular part 16 of the insert 4 are slightly smaller than the corresponding outside and inside diameters of the outer annular part 6 of the reserve 5 and the dimensions of the body 13 are slightly smaller than those of the central deeper part 7 of the reserve so that the insert can be fitted into the reserve with a relatively small predetermined tolerance, taking account of the aesthetic nature that the container 1 affords. The thickness of the annular part 16 of the insert 4 is slightly less than the depth of the annular part 6 of the reserve 5, advantageously, so that, when the insert is in place, the exterior face of the sealing plate 15 is flush with the exterior face of the wall 3 of the container 1. The exterior lateral faces of the annular part 16 and of the dish-shaped body 13 of the insert have angles of inclination corresponding to angles α and β of the annular part 6 and the central part 7 of the reserve 5.
According to one embodiment of the invention, the insert 4 is fixed in the reserve 5 by bonding using an adhesive, preferably an invisible one, applied to at least one of the opposing faces of the annular part 16 of the insert 4 and of the annular part 6 of the reserve 5, that is, the rear face 17 allowing the annular part 16 of the insert 4 to be secured to the corresponding inside end face 19 of the annular part of the reserve 5.
In one embodiment of the invention, to prevent the adhesive-covered regions of the face 17 or the face 19, or both, from being visible through the container, at least one of these two faces can be opacified, for example given a grained appearance, or decorated accordingly.
Given that the insert 4 is fixed in the reserve 5 by bonding only at the annular faces 17 and 19, it is possible to provide on the inside end wall portion 20 of the reserve 5 and/or on the end wall 21 of the body of the insert 4, a raised pattern which can be colored if appropriate. This pattern can constitute or form part of a decoration, such as a relief, for use with animation means provided inside the insert 4, for example, in a fluid with which the insert is filled. These animation means could be elements in the form of beads able to move in the fluid according to the way in which the container is handled, for example, according to changes in position. This animation can be, for example, similar to the movement of simulated snow in a snow globe.
Given that the insert 4 is fixed into the reserve 5 on the outside of the region of animation visible through the walls of the container 1, the height c of the internal space of the insert can be varied in order to influence the movement of the animation elements.
It should also be noted that the inclined lateral faces of the body 13 and of the sealing plate 15 make it possible, when these elements are fabricated by molding, to be molded with easy mold release elements.
In one embodiment of the invention, a pluggable filling hole 22 is made in the lateral wall of the body 13 of the insert 4.
In another embodiment of the invention, the insert 4 can be formed with a stud 23 for positioning the insert in the reserve 5, which reserve is then provided with an appropriate hole 24 for accommodating the stud.
Similarly, the sealing plate 15 can be positioned on the body 13 of the insert 4 by means also involving one or more studs and an accommodating hole or holes.
While the insert and reserve used to illustrate the invention are described above as being circular, the invention can employ other shapes for the insert and the reserve, for example, rectangles, ovals, triangles, or complex shapes. Accordingly, the word ‘annular’ used throughout this specification means ‘at least partially surrounding’, in other words, ‘adjacent and outside’ and is not necessarily limited to completely surrounding or circular shapes.
As shown in FIG. 7, in an embodiment in which the insert and the reserve are primarily circular, one or more positioning cuts 30 are made in the annular part 16 and corresponding positioning stops are made in the reserve 5. These cuts 30 act as a ‘key’ to properly position the insert 4 within the reserve 5 so that if the insert has a preferred orientation, for example, a decoration portraying a tree or village, the insert will only fit into the reserve in the preferred orientation. The cuts 30 can be made at approximately 90 degrees relative to the preferred top of the insert 4 and should not be parallel to each other and/or be the same size as each other to provide only one possible rotational position for the insert in the reserve 5.
Also, as shown in FIG. 7, one or more glue reservoirs 32 can be formed in the annular part 16 for holding the adhesive. In one embodiment, three such reservoirs 32 are positioned equidistantly about the annular part 16.
While the present invention has been described in terms of specific embodiments, this invention encompasses all variations and modification, including expedients by those skilled in the art, which come within the spirit of the specification and the scope of the appended claims.
