Definitions
- the present invention relates to an assembly device between two tubular elements as well as the tubular elements allowing the implementation of such an assembly device.
- metal containers are mainly of general cylindrical shapes, of very different heights and diameters depending on the regions of the world and have a very wide variety of crimped collars on their upper part.
- These flanges have more or less complex profiles to ensure both the rigidity of the top of the box and the nesting by pressing of a metal wafer serving as a closure cover for one package.
- the cover can be of complex design, in particular when it incorporates a stirring device and means for opening / closing a pouring spout.
- These agitator and / or pouring lids have always had the problem of adapting to the very wide variety of box flanges while guaranteeing good sealing. Indeed, these agitator and / or pourer covers are used very downstream of the paint industry at the level of the end user. The challenge for the next few years is to develop a packaging capable of eliminating a flange while offering a universal and versatile assembly solution for all types of lids that can be adapted at any time. of the life cycle of a box.
- Patent FR-A-2,538,349 describes an elastic assembly device in which the cover is provided with tabs which grip the lower part of an annular bead of the container body. Again, such a device does not make it possible to obtain sufficient clamping forces to guarantee efficient assembly. In addition, it proposes replacing the cams with another equally complex mechanical connection system.
- patent EP-A-1,153,844 discloses an assembly by screwing requiring the addition of a threaded ring around the periphery of the container. Closing or opening the threaded cover requires several turns of the cover.
- An object of the present invention is to propose a new assembly device and new tubular elements assembled by means of such a device, the designs of which allow blind assembly on a fraction of a turn while ensuring excellent uniformly distributed mechanical tightening. around the perimeter of the assembly area.
- Another object of the present invention is to propose an assembly device and tubular elements assembled by means of such a device, the designs of which make it possible to generate radial and axial clamping forces ensuring on the one hand, by their orientation, a strengthening of the tightness of the assembly, on the other hand, by the off-centering or eccentricity of the radial forces, a strengthening of the tightening so as to prevent any untimely disassembly.
- Another object of the present invention is to provide an assembly device and tubular elements assembled by means of such a device, the designs of which make it possible to keep the assembly means constantly accessible in order to be able to act on them, other than by a rotating action, in particular in the case where the content of one of the elements tubular blockage of disassembly.
- Another object of the present invention is to provide a new packaging solution combining a box and a cover without any additional mechanical means other than the use of profiled inertia sectors of such kinds that they make it possible to ensure a direct connection between the external body of a covered tubular element and the internal body of a covering tubular element.
- Another object of the present invention is to provide a simplified assembly device as economical as possible in particular between an agitator and / or pouring cover and a box by eliminating the fixing cams which have the drawbacks of reducing the sealing performance. of the agitator and / or pourer cover, to degrade the interior protective coatings of metal containers favoring the appearance of rust, to require far too much time in the positioning of the agitator and / or pourer cover on a box.
- Another object of the present invention is to provide an assembly device between an agitator cover and a metal box allowing the removal of the upper flange of a box to ensure complete emptying of the paint contents of the box.
- the invention relates to an assembly device between two tubular elements such as a container body and a partial or total closure member, assembled or disassembled by the effect of partial relative coaxial rotation, this device consisting on the one hand of first and second coupling means, on the other hand of first and second means guide respectively disposed each time on the respectively inner and outer faces intended to come opposite the tubular elements to be connected, characterized in that the first and second guide means consist of a plurality of guide ramps inclined in the direction of the closure and brought into bearing contact during a relative coaxial displacement in rotation of the tubular elements to cause an axial overlap of said tubular elements and in that the first coupling means consist of a plurality of locking blocks formed in the inner wall of the tubular covering element and arranged respectively between two x adjacent inclined ramps of the tubular covering element, an outer face of each of said blocks coming, during assembly in the superimposed state of the covering element and the covered element, to be positioned under a second means d coupling of the covered tubular element to cause radial and axial tight
- the tubular covering element has the general shape of a cover, the top of this cover having openings arranged in line with the locking blocks to give the covering wall of the cover an elasticity radial contributing to the radial and axial clamping of the block with the second coupling means of the covered tubular element.
- openings offer a significant number benefits. It makes it possible in particular to create an elasticity of the tightening or contact point in order to generate additional efforts to maintain the friction of the surfaces which promote the wedging effect.
- the mechanical forces are offset so that the covering tubular element can in no case be released without voluntary action.
- this elasticity helps the surfaces in contact to remain conjugated in all circumstances thanks to mobility in space from the clamping zone.
- these openings allow, in certain configurations of the means of sealing 1, to contribute to this tightness. Finally, they make it possible to carry out a disassembly of the tubular elements when, for example, the tubular elements are used for packaging products liable to dry, such as paint, the drying being able to generate a disassembly blocking.
- the openings can constitute windows of visual indication for information of the open / closed positions. Furthermore, these openings facilitate the manufacture of an elastic clamping block in undercut without complicating the industrial process.

- Figures 8 and 9 show mathematical models and geometric configurations of the second guide means and coupling of the assembly device.
- the assembly device is intended for the assembly of two tubular elements 1, 2 assembled and disassembled by the effect of partial relative coaxial rotation.
- These tubular elements 1 and 2 can be constituted, for example, by a container body and by a partial or total closure member such as a cover.
- a container body and a cover intended in particular for the sealed packaging of paint, the cover possibly being an agitator and / or pouring cover incorporating a pouring spout closable by means a suitable closing device incorporated into the cover.
- the assembly device consists on the one hand of first 5 and second 6 coupling means, on the other hand of first 3 and second 4 guide means respectively disposed each time on the respectively outer and inner faces intended to come next to tubular elements 1, 2 to be connected.
- first coupling means 5 and the first guide means 3 are formed in one tubular covering element 2 constituted by the container cover on the inside of the covering wall of the cover while the second means guide 4 and the second coupling means 6 are provided on the outer wall of the container body 1 either directly on this wall, or on a ring 10 attached to this container body as illustrated in FIG. 1.
- the guide means 4 and coupling 6 can be made in one piece with the body of the element.
- this covered tubular element 1 can be made of many materials, in particular metal.
- the guide means 4 and coupling means 6 are provided on a ring 10 attached to the body of the covered tubular element 1, the ring can again be made of metal or of synthetic material.
- the first guide means 3 and coupling 5 can be made in one piece with the tubular element covering 2 as 1 'illustrate the figures or be made as an insert.
- the first and second guide means consist of a plurality of guide ramps 3 and 4 inclined in the closing direction, these guide ramps being brought into bearing contact during a coaxial movement relative in rotation of the tubular elements 1, 2 to cause an axial overlap of the tubular elements 1, 2.
- direction of closure is meant a displacement in rotation of the elements in a direction leading to the assembly of said elements while the direction of opening corresponds to a relative displacement in rotation of the elements bringing them in disassembled position.
- the axis of rotation around which the elements 1 and 2 move is shown at X, X 'in FIG. 1.
- the direction of rotation adopted for the direction of closure corresponding to an assembly of the tubular elements 1 and 2 is here a direction schedule represented by the arrow F and which corresponds to the usual practice of the users.
- the guide ramps are thus arranged at intervals on the inner peripheral periphery of the tubular covering element 2 and on the external peripheral periphery of a covered tubular element 1.
- These ramps consist each time of normal or substantially normal surfaces to the walls of the bodies, these surfaces developing along a helix of the body.
- the assembly device comprises, in addition to first and second guide means, first and second coupling means.
- the first coupling means consist of a plurality of locking blocks 5 formed in the inner wall of the covering tubular element 2.
- Each block 5 is axially offset relative to the inclined rails 3. From preferably, the number of ramps is equal to the number of pavers.
- An outer face 5A of the block 5 comes, during assembly, in the superimposed state of the covering element 2 and of the covered element 1 as shown in the figures, to be positioned under the second coupling means 6 of the covered tubular element 1 to cause a radial and axial tightening of the tubular elements 1, 2 connected.
- the top 2A of this cover has openings 7 arranged in line with the blocking blocks 5.
- These openings 7 give the covering wall 2B of the cover 2 a radial elasticity contributing to the radial and axial tightening of the block 5 with the second coupling means 6 of the covered tubular element 1. It results from the presence of these openings 7 a large number of advantages as mentioned above. Indeed, these openings 7 in particular allow access to the first and second coupling means in particular by introduction of a flat tool through the openings 7.
- the cover is provided with a frustoconical annular rib 11 intended to be inserted inside a cavity of the container body, cavity delimited by means of a flange 12 positioned in the vicinity of the upper edge of the container body.
- the means 4 for guiding and coupling 6 of the covered tubular element 1 are in the form of a sector with progressive section formed on the outer face of the wall of the covered tubular element 1 to define a flat guide face 4A and normal or substantially normal to the wall of the covered tubular element 1 and cooperating with the first guide means 3 of the tubular covering element 2 and an assembly face 6A inclined with respect to the wall of the covered tubular element 1.
- the sector is oriented on the wall of the covered tubular element 1 in the manner of an interrupted screw thread.
- the sector constituting the second coupling means 6 of the covered tubular element 1 has a triangular section with progressive section in the direction of closing (see section SI , section S2-, section S3) with a base resting on the outer wall of the covered tubular element 1 and a helical spiral edge 8 (Ai, A 2 , A 3 ) projecting separating the guide face 4A from the face assembly 6A.
- the triangular section of the sector constituting the second coupling means 6 of the tubular element increases in size.
- FIG. 9 illustrates in particular the projection of the surfaces with the cover. It shows in particular a top view as well as a front view of the projected profile.
- ⁇ 2 corresponds to the angle of rotation of the cover between Ai and A 2 expressed in radian
- ⁇ to the angle of the propeller
- X 2 to the radial distance between Ai and A 2
- Y 2 at the axial distance between Ai and A 2
- R 0 at the initial radius of the tubular element 1
- R at the radius of the element 1 or after radial expansion of the zone of the element intended to include the guide means and d coupling of the covered tubular element 1, either after positioning a ring on the element 10 intended to receive the guiding and coupling means, 0 at the center of the circle delimiting the wall of the element 1, e to the difference between R and R 0 and C at the offset center of r and of an angle of the circle corresponding to the arc of a circle of radius Ri defined by the points Ai, A 2 , A 3 , A 2 corresponding to the point of contact of the assembly face 6A of the profile with the external face 5A of the locking block, this assembly face 6A being inclined at
- the connecting sectors are therefore of progressively more massive triangular section in the direction of closure.
- This change in the general shape of the profile with an undercut induces a non-deformable zone in the locking contact under the combined effect of the radial and axial forces.
- the beginning of the section is thin but very wide and its termination, place of tightening, is less wide but thicker.
- This specific widening of the profile is much more resistant to external aggressions and contributes to the creation of a box and lid assembly of great rigidity, in particular in the hypothesis of the absence of a flange set on the top of the box.
- the outer face 5A of contact of the block 5 with the second coupling means 6 is in turn profiled to match the profile of the inclined face 6A of the sector constituting the second coupling means 6.
- the blocks 5 of locking, formed on the inner face of the wall of the tubular covering element 2 respectively affect the shape of a solid of which at least a part of the surface of the outer face 5A active clamping is generated by the displacement of a progressive inclination line ⁇ between points A1 and A3 to follow the trajectory of two portions of the curve, one helical upper spiral, close to the top of the tubular covering element, the other lower elliptical, said portions of curve developing axially offset 1 inside the tubular element covering 2 in a cylindrical sector, the spiral helical curve developing along u n angle increasing in the closing direction with reference to the axis of the covering tubular element 2.
- the angle of the spiral of the upper curve is identical to that of the helical helical edge 8 of the covered tubular element 1. Obviously, this surface can be extended beyond the
- the blocks 5 for locking the tubular element covering 2 assume the shape of a polyhedron with two lateral faces 5B trapezoidal of different surfaces and at least one face 5A of curved contact to match the profile of an inclined face 6A constituting the second coupling means 6 of the covered tubular element 1. It should be noted that the top face of this polyhedron constitutes a non-active face and can therefore affect a large number of shapes.
- the tubular covering element 2 such as a cover, will therefore include guide means 3 and coupling means 5 in accordance with those described above.
- the guide ramps 3, constituting the guide means of the tubular element covering 2 and which are inclined in the direction of closure and which extend between two adjacent locking blocks 5, have a delimiting notching a clearance 9 authorizing a sliding of the locking blocks 5 along the coupling means 6 until complete tightening.
- this tubular covering element 2 can, as has already been specified above, have a large number of shapes.
- the top 2A of the cover 2 has a pouring spout and is crossed by a stirring device. This cover then constitutes an agitator and / or pourer cover well known to those versed in this art.
- this covered tubular element 1 can, as mentioned above, be made in one large number of materials. It could in particular be made of metal.
- the guide means 4 and coupling 6 may be made in one piece with the body of the element. It may be the same in the case of a tubular element made of synthetic material.
- the guiding means 4 and coupling 6 may also be provided on a ring 10 attached to the body of the element, as illustrated in FIG. 1. In all cases, the different production techniques must entail the use a cover with the same characteristics.
- the wall of the element 1 of medium radius R 0 must be extended to a wall of medium radius R equivalent to the wall of the element 10.
- the profile can advantageously be reduced to the functional portion between the curve (Ai , A 2 , A 3 ) and with the cylindrical protrusion of medium radius R for facilities for producing the profile with progressive triangular section, in particular in a metallic material where the maximum stretching of the material must be compatible with the manufacturing processes of the box.
- FIG. 3 thus represents the start of the assembly in which the inclined guide rails 3 and 4 come into bearing contact.
- each locking block gradually comes to be positioned under the means 6 for coupling the covered tubular element 1 to come to a contact position shown in FIG. 5 before allowing radial and axial tightening of said walls in contact, this tightening being shown in FIG. 6.
