    [0001] TECHNICAL FIELD The invention relates to a rigid envelope intended to cover a tube comprising a liquid or pasty product. This tube is flexible and is gradually compressed as and when dispensing the product. The rigid casing thus makes it possible to maintain a substantially constant external appearance, it also makes it possible to protect the tube against any involuntary compression. STATE OF THE PRIOR ART Among the containers containing cream or paste products, there is a container in the form of a flexible tube that is pressed to release its contents. Depending on the elasticity or otherwise of its walls, the tube may tend to return to its original shape after releasing the pressure applied to it. In doing so, air is drawn into the tube to compensate for the volume of product that can be taken. Some tubes are equipped with anti-return devices to automatically close the dispensing orifice, to prevent air from entering the tube. Also, the tube is deformed gradually by crashing, as and when samples of product. These deformations of the tube adversely affect the general appearance of the tube. Also, deformation of the tube, while its dispensing tip is still closed, for example by a plug of the type snap on the tip, produces a positive pressure of the product in the tube. The product can then exit through the dispensing nozzle in an uncontrolled manner, which is unpleasant for the user.
    [0002] US-1,889,885 discloses a rigid casing for protecting a product delivery tube such as toothpaste. This envelope consists of two plates between which the product tube is placed.
    [0003] These two plates partly envelop the dispensing tube, to protect it from a large part of the stresses it could undergo. However, this envelope does not completely cover the dispensing tube, so that it is clearly visible from the outside, which is not aesthetic.
    [0004] Also, the envelope described in this document is made in two parts that are movable relative to each other, to allow the mounting of the tube therebetween. Handling the two parts and means for their attachment can be difficult for a user. In addition, the tube is secured to the casing at its end at which the dispensing tip is located. This therefore reduces the stability of the tube in the envelope and exposes it to external stresses. DISCLOSURE OF THE INVENTION The invention proposes a rigid casing for a flexible tube comprising a main longitudinal orientation body, which consists of an upper wall, a lower wall located opposite and at a distance from the upper longitudinal wall and two lateral walls connecting the upper wall with the lower wall, a rigid head located at a longitudinal front end of the body which comprises a central orifice, characterized in that it is made in one piece from a rigid material.
    [0005] The realization of the envelope in one piece makes it easier to use since the user does not need to manipulate different parts during assembly of the flexible tube.
    [0006] Preferably, the rear longitudinal end of each side wall carries a boss projecting inwardly with respect to the inner face of said side wall. Preferably, each boss has an open groove 5 longitudinally forward. Preferably, the bottom wall has a longitudinal opening which is open at the rear end edge of the bottom wall. Preferably, said opening has a leading edge which is located behind the front end edge of the bottom wall.
    [0007] Preferably, one and / or the other of the upper wall and the lower wall is substantially planar. Preferably, one and / or the other of the upper wall and the lower wall is convex curved towards the outside of the envelope. Preferably, and / or the other of the upper wall and the lower wall is trapezoid-shaped whose parallel sides of the trapezium are formed by the front and rear longitudinal end edges of said upper wall or said lower wall. . The invention also proposes an assembly comprising a rigid envelope according to the invention and a flexible tube disposed inside the envelope, said tube comprising a body of deformable material, a front end comprising a dispensing orifice, and a closed rear end, characterized in that the tube is held in position in the casing by an elastic interlocking of the front end of the tube in the front end of the casing. Preferably, the body shape of the envelope is similar to the shape of the body of the tube. BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended figures in which: FIG. 1 is a schematic representation for the purpose of top of an envelope according to the invention; - Figure 2 is a bottom view of the casing shown in Figure 1; Figure 3 is an end view of the rear end of the casing shown in Figure 1; FIG. 4 is an end view of the front end of the casing shown in FIG. 1; FIG. 5 shows different shapes of the upper face or the lower face of the envelope shown in FIGS. 1 and 2; FIG. 6 shows an exemplary shape of the front end of the envelope shown in FIGS. 1 and 2; - Figure 7 shows different shapes of the rear end of the envelope shown in Figures 1 and 2; FIG. 8 is an enlarged detail of the front end of the body and of the tube, showing the fastening means by clipping; - Figure 9 is a view similar to that of Figure 8, for which the closure of the dispensing orifice of the tube is effected by a movable lid. DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS FIGS. 1 to 4 show an envelope 10 containing a flexible tube 12. The flexible tube 12 contains a pasty or liquid product, such as, for example, a cosmetic cream. The tube 12 comprises a body 14 of deformable material, a front end 16 comprising a dispensing orifice, and a closed rear end 18. According to an exemplary embodiment, the body 14 is obtained from a tubular cylinder which is closed at its rear end by folding to form a straight edge constituting the rear end 18 of the tube 12.
    [0008] It will be understood that the invention is not limited to such a flexible tube and that the shape and / or dimensions of the tube 12 may be different from that shown in the figures. For example, the body of the tube 12 may be of frustoconical or curved main shape. The front end 16 of the tube 12 is of similar shape to the main section of the cylinder for producing the body 14 of the tube 12. Here, as can be seen in particular in FIG. 4, the shape of the front end 16 of the tube is circular. It will be understood that the invention is not limited to this form, the front end 16 of the tube may also be oblong or oval for example. The envelope 10 is intended to cover at least part of the tube 12. The envelope 10 comprises a body 20 which defines a volume in which the body 14 of the tube 12 is received, a front end 22 which cooperates with the front end 16 of the tube 12 and a rear end 24 which cooperates with the rear end 18 of the tube 12. The casing 10 is preferably made in one piece, for example by molding a plastic material or any other material . Thus, the body 20, the front end 22 and the rear end 24 of the casing 10 are parts in one piece.
    [0009] The front end 22 of the casing 10 is of associated shape, and preferably complementary to the shape of the front end 16 of the tube 12. Here, the front end 16 of the tube 12 is of conical shape, the front end 22 of the envelope 10 is also conical. It comprises a central orifice 32 which is intended to be traversed by a nozzle 34 for dispensing the tube 12. The body 20 surrounds the body 14 of the tube 12. It comprises an upper face 26 and a lower face 28, the two upper faces 26 and lower 28 are interconnected by side walls 30. These four walls 26, 28, 30 of the body 20 are distributed around the body 14 of the tube 12.
    [0010] The shape of each of the walls of the body 20 is defined so that the body 20 envelops the body 14 of the tube 12 as far as possible. Here, as can be seen in FIGS. 1 to 3, a clearance is present between the body 14 of the body tube 12 and the walls 26, 28, 30 of the body 20 of the casing 10. According to an alternative embodiment, the body 14 of the tube 12 is received without play in the body 20 of the casing 10, when the tube 12 is full. The material constituting the envelope 10 is a relatively rigid material, in particular it is more rigid than the material constituting the body 14 of the tube 12. Thus, when the tube 12 is inside the envelope 10, it is protected against external pressures which may cause the product to be unwanted. This material can be transparent, to allow a user to visualize inscriptions that would be placed on the walls of the body 14 of the tube 12. This material can also be opaque or translucent, allowing on the contrary to mask inscriptions that would be placed on the walls. body walls 14 of the tube 12. Inscriptions may also be arranged on the walls 26, 28 of the body 20 of the envelope 10, whatever the type of material of the envelope, to replace or complete the inscriptions of the tube 12.
    [0011] As mentioned above, the body 20 of the casing 10 completely surrounds the body 14 of the tube 12, protecting it from external stresses. To allow a user to exert a bias on the body 14 of the tube 12, in order to take a certain amount of the contained product, the bottom wall 28 of the envelope 10 has an opening 36 through which for example a finger of the user can pass, to press on the body 14 of the tube 12. Here, as can be seen in Figure 2, the opening 36 extends along the longitudinal main direction of the casing 10, from rear end edge 28a of the bottom wall 28, at which the opening 36 is open, up to approximately the front end edge 28b of the bottom wall 28.
    [0012] The front edge 38 of the opening is thus located behind said front end edge 28b of the bottom wall 28, at which the bottom wall is connected to the front end 22 of the envelope 10. The shape the opening 36 is here mainly rectangular, that is to say that the opening has two longitudinal edges 40 located at a distance from one another and a front edge 38. The opening 36 is furthermore opening at its rear end. As a variant of the invention the shape of the opening 36 is different, it is for example oblong, with a front edge 38 in the shape of a circular arc, or the opening 36 is not open at its end. rear, which is therefore located at a distance and in front of the rear end edge 28a of the bottom wall 28. Thanks to this opening 36, a user can, by compressing the body 14 of the tube 12 between his finger and the upper wall 26 of the envelope, generate a pressure on the product contained in the tube, so that a certain portion of the product emerges through the tip 34. The dimensions and shape of the opening 36 are defined to allow the user to press on the entire body 14 of the tube 12, so that it is possible to extract all of the product contained in the tube 12.
    [0013] The casing 10 is open at its rear end 24, which allows insertion of the tube 12 into the body 20 through this rear end 24 in a main longitudinal translation movement. The rear end 24 of the casing 10 further comprises means for retaining the tube 12 in the casing 10. These retention means here consist of two bosses 42, each of which is carried by the rear longitudinal end of the casing. internal face of a side wall 30. Each boss 42 protrudes inwardly relative to the inner face 30i associated to form a stop member against which the rear end 18 of the tube 12 abuts longitudinally rearwardly when the tube 12 is in position 30 inside the envelope 10.
    [0014] The installation of the tube 12 in the envelope 10 is thus done by gradually inserting the tube 12 into the envelope 10 through the opening of the rear end. The tube 12 has previously been moved relative to its final position 5 in the envelope 10 so that the insertion is not prevented by the bosses 42 and the tube is not deformed by contact with the bosses 42. This displacement is carried out either by turning the tube 12 around its longitudinal main axis, or by shifting the tube 12 slightly downwards or upwards, with respect to its final position, to be offset relative to the bosses 42.
    [0015] The dimensions of the body 20 of the envelope 10 are defined to allow insertion of the tube 12 into the envelope 10. According to the dimensions and the general shape of the tube 12, the tube 12 can then be received in the envelope 10 with some functional game. However, the dimensions of the body of the envelope 10 are also defined to prevent any exit of the tube 12 from the envelope 10 because of the presence of these clearances between the tube 12 and the faces of the body 20. As can be seen in FIG. see figure 8 and 9, the tube 12 is held in position in the casing by an elastic interlocking of the front end 16 of the tube 12 in the front end 22 of the casing 10.
    [0016] Preferably, the resilient interlock is made at the base of the tip 34 of the tube 12 which is nested in the central orifice 32 of the front end 22, after the end piece 34 has completely passed through the central orifice 32. For example, as shown in Figure 8, the tip 34 of the tube 12 has an external thread 46 for screwing a plug (not shown) 25 to seal the tip 34 and the base of the tip 34, which is located below this thread 46 has a flange 48 of greater diameter than the outer diameter of the thread. The diameter of the central orifice 32 is greater than the diameter of the thread 46 of the tip 34 and is smaller than the external diameter of the collar 48.
    [0017] Also, the flange 48 has a conical front face 50 defined to facilitate an elastic deformation of the front end 22 of the casing 10 at the central orifice 32, when the endpiece is introduced through the central hole. The collar 48 also has a conical rear face 52 which bears against the edge of the central orifice 32 when the endpiece 34 is completely inserted. The opening angle of the front face 50 is much smaller than the opening angle of the rear face 52, so that the support of the rear face allows the stay in place of the endpiece 34 in the orifice. central 32.
    [0018] According to the embodiment shown in FIG. 9, the end piece comprises a cover 54 which is articulated on the end piece 34 and which closes. The outer wall of the nozzle 34 is smooth and comprises only a flange 48 similar to that described above, having a conical front face 50 and a conical rear face which bears against the edge of the central orifice 32.
    [0019] These two conical faces cooperate with the edge of the central orifice 32 as previously described. It will be understood that the invention is not limited to this embodiment of the retaining means by elastic interlocking, and that the retaining means can be arranged at another position in the envelope, for example at the level of the edge. rear end of the front end 22 of the casing 10. To complete the holding means by elastic interlocking for the longitudinal retention of the tube inside the casing 10, each boss 42 has a groove 44 which is open longitudinally forward. The two grooves 44 of the bosses 42 are intended to receive the flattened rear end 18 of the tube 12. The grooves 44 of the bosses 42 perform both the longitudinal retention of the rear end 18 of the tube 12 and the maintenance in vertical displacement upwards or downwards of the rear end 18 of the tube 12. FIG. 5 shows different embodiments of the shapes of the upper and lower walls 26 and 28. these walls is identical and is defined according to the shape of the tube 12 which is intended to be disposed inside the envelope 10. According to a first embodiment, the two walls 26, 28 are of rectangular shape, as for the embodiment of Figures 1 and 2.
    [0020] According to a variant, the two walls 26, 28 are in the form of an isosceles trapezium, whose parallel sides or bases are formed by the front and rear end edges of the walls 26, 28. The large base of this trapezium is thus located at the front end or at the rear end of each wall 26, 28. In addition, according to one embodiment, one and / or the other of the two walls 26, 28 is substantially flat. According to an alternative embodiment, one and / or the other of the two walls 26, 28 is substantially curved and is curved towards the outside of the envelope. According to the embodiment shown in FIG. 4, the front end 22 of the envelope 10 is of conical shape of revolution, that is to say that its section in a plane perpendicular to the main axis of the envelope is circular. According to an alternative embodiment shown in Figure 6, the section of the front end 22 of the casing 10 is oblong, the direction of the largest dimension of this section may be vertical or horizontal. Finally, as shown in FIG. 3, the rear end 24 of the envelope 10 is oblong, the large dimension of which is substantially equal to the width of the rear end 18 of the tube 12. This oblong shape the rear end 24 of the envelope 10 applies with any shape and any size of the front end 22 of the envelope 10, as shown in FIG. 7.
    [0021] According to a first example, the large dimension of the rear end 24 of the casing 10 is substantially equal to the diameter of the front end 22 of the casing 10 which is circular in shape. In a second example, the large dimension of the rear end 24 of the casing 10 is smaller than the diameter of the front end 22 of the casing 30 which is circular in shape.
    [0022] According to a third example, the front end 22 of the envelope 10 is also of oblong shape, as shown in FIG. 6 and its large dimension is greater than the large dimension of the rear end 24 of the envelope. 10. 5
