Definitions
- the invention relates to a method of manufacturing metal cans, made of low carbon steel or aluminum alloy, produced by deep drawing, stamping - drawing, or by extrusion, the internal wall of which is covered with a protective coating and which are provided with a threaded neck intended to fix any type of removable head, for example aerosol spray dispensing heads, of the eco-refill type but also suitable for fixing a closure capsule.
- the threading is generally carried out so far using an internal tool with a helical imprint, essentially playing a role of support and shaping mold, and an external tool acting as one or more knurls .
- European patent application EP 0 510 291 (NUSSBAUM) describes an improved threading process, where the thread (s) is (are) shaped using internal tools and a external tool, the rotation of each of them being controlled in a coordinated manner and so that a slip is made between the material of the neck and each tool. This prevents the metal from the neck from accumulating and bending upstream of the external threading tool and is pushed back in the direction of advancement of the tool. The neck is then cut on the same device, that is to say without the container having been dismantled, leaving a bare surface on the rim surrounding the orifice, that is to say unprotected or free burrs.
- the housing thus obtained does not allow the dispensing head to be placed precisely with respect to the rim and the shoulder. We cannot control the positioning of the heads well and this has harmful consequences both on the tightness of the assembly and on its aesthetic appearance.
- the method according to the invention is a method of manufacturing a metal case comprising at least the following steps: a) production, for example by deep drawing, drawing - drawing, spinning or drawing-drawing, of a case having a bottom and a cylindrical wall or
- step 25 of shape step possibly followed by a deposition of paint or varnish at least on the internal surface of the cylindrical wall, followed by an annealing treatment of the varnish; b) shrinking intended to make a neck on the open end of the housing, step possibly followed by a cut perpendicular to the axis of the housing
- the method is characterized by the use of a ring, for example molded in plastic material (but it could also be in any other material: metal, machined or matrix, etc.), of generally toric shape, with an internal wall cylindrical, which we will call hereinafter central bore and a cylindrical outer surface provided with a thread.
- the central bore has a diameter slightly greater than the outside diameter of the neck which has just been formed on the housing, so that the fitting of the ring can be done freely.
- the thread produced on the outer surface of the ring is preferably a standard thread, for example with a triangular or trapezoidal section, more suitable for the precise positioning of the distributor head relative to the metal case.
- a standard thread for example with a triangular or trapezoidal section, more suitable for the precise positioning of the distributor head relative to the metal case.
- this step can be carried out during the same tightening phase of the housing, that is to say that these operations can be carried out on the same machine, the boxes being mounted on a rotary circular table whose rotation step by step brings them successively in front of different tools, adapted to each of these stages and mounted themselves on a circular tool plate.
- a device of this type has already been described, for example in FR 1 434 1 77 (LECHNER).
- the shape of the first end of the ring can be arranged so that it fits, hollow, on the shoulder of the case. It is also possible, preferably, to arrange a small shoulder on the neck, located at a certain distance from the rim of the neck. This distance can be very precise when the production of the shoulder is carried out in conjunction with the optional cutting of the end of the neck of step b).
- the ring also has a surface which comes into abutment in contact with the shoulder arranged on the neck. This surface is for example obtained by making a shoulder in the central bore.
- the shoulder made on the neck must be sufficiently "high" (radial height) so that it serves as a stop for the corresponding surface of the ring during its installation, that is to say before the swelling of the collar.
- this stop system acting at the end of the fitting of the ring, the height of the neck which comes out of the central bore is controlled. It is advantageous, during a subsequent step, to roll outwards this part which exceeds the ring so that it traps it and prevents any axial movement of recoil.
- the protruding height is therefore chosen so that it allows a rolled edge to be produced, for example by stamping. It depends on the outside diameter of the plastic ring and the inside diameter of the neck.
- the swelling of the neck is preferably carried out over its entire length, so as to obtain the largest possible contact surface between the neck and the ring after swelling.
- the strength of the connection between ring and neck depends on the extent of the swelling and the extent of their contact surface.
- the extent of swelling is limited by the ductility of the neck material.
- the contact surface depending at first order on purely geometric conditions, is an easier parameter to control.
- the swelling consists in plastically deforming by expansion a metal which has already undergone a strong deformation during the shaping of the cylindrical box (deformation all the more strong as one is near the free edge of the box) then a strong constriction. The metal is therefore in a very hardened state, characterized by strong mechanical characteristics but a low residual ductility.
- the limit value not to be exceeded depends on the nature of the metal and the geometry of the housing to be obtained and can be determined experimentally using simulation tests reproducing on the metal considered the thermo-mechanical conditions of the different stages of the shaping process considered.
- a swelling will be carried out such that it results in an increment of plastic deformation greater than 2% at the level of the internal wall of the neck.
- the upper limit of this plastic deformation increment varies as a function of the ductility of the chosen alloy, the strain-hardened state of which turns out to be favorable for good ductility in circumferential expansion.
- the clearance between the bore of the ring and the neck remains close to a tenth of a millimeter and the diameter internal of the cervix is increased after swelling by about 0.3 mm, which corresponds to an increment of plastic deformation of about 2% at the internal wall of the cervix.
- the process is advantageously followed by the following steps: e) rolling, for example by dabbing, of the end of the neck. f) smoothing, consisting in moving a wheel resting on the rim of the neck formed by rolling the previous step and intended to improve the surface condition of the layer of varnish
- the edge is preferably rolled outwards, because in this case it allows the ring to be axially blocked, preventing any axial movement of withdrawal.
- the function of the rolled edge is above all to improve the tightness of the assembly, because it forms a rim covered with varnish and rounded, that is to say of toroidal shape with circular section, much more suitable for the tightness that the raw cutting beverage, not covered, flat and not systematically free from burrs of the prior art.
- this geometry eliminates any risk of contact of the packaged product with the metal slice possibly not protected by a varnish.
- the varnished layer certainly suffers during rolling a new damage which results in a disturbed surface state, crossed by roughness and micro-cracks, quite similar to that which is observed on the threads obtained directly by knurling.
- the following smoothing operation is intended to improve this surface condition, by plugging the cracks and leveling the roughness.
- the ring is made of plastic, it is recommended to take into account the relaxation of stresses which inevitably occurs in such a material and which has the consequence of reducing the intensity of tightening a few hours after swelling. Taking into account the geometric manufacturing tolerances, it is possible that this loosening is significant, that is to say such that the ring can no longer resist the torque of unscrewing the head, which makes it trapped in the housing without for as much to ensure sealing. In such a situation, the housing becomes unfit for use.
- a container with a metal case provided with a neck intended to be secured with any type of removable head (of the eco-refill type), the head being provided with fastening means, such as a thread, a bead or a latching groove, characterized in that it comprises a ring provided with fixing means complementary to those of the head, said ring adhering to the neck of the metal case with a sufficiently strong connection to resist detaching torque of the removable head.
- the dispensing head is generally covered by a protective capsule which is provided with a cylindrical skirt which extends up to near the shoulder of the housing.
- a protective capsule which is provided with a cylindrical skirt which extends up to near the shoulder of the housing.
- this lower end of the skirt and the lower end of the ring with means for guaranteeing the inviolability of the container, for example a tamper-evident system by radial snap-fastening (vertical fastening). or notches inside a breakable tamper-evident band (plastic rings with tamper-evident and multi-notch notches).
- the ring used in the context of this invention gives, by its presence, the possibility of having metal boxes of the eco-refill type provided with means of guarantee of inviolability.
- the knurling used in the prior art not only leads to a rounded and imprecise thread but does not allow a sufficiently steep relief to be produced, making it possible to trap a band of guarantee of inviolability.
- this abrupt relief can be easily obtained during molding, for example by giving a larger outside diameter to the first end of the ring.
- This end thus plays the role of a counter-ring, the rim of which can trap a tamper-proof band, for example connected to the lower end of a capsule skirt by a plurality of breakable bridges, such as that described in EP 0 107 680. It is also possible to equip this counter ring with ratchet teeth and reproduce the means of guaranteeing inviolability described in FR 2 665 142. The latter have the advantage of not requiring a significant torque to detach the strip.
- Figure 1 shows a housing with threaded neck of the prior art associated with a distributor head base having a bore intended to receive the pump which makes it possible to distribute the product in the form of spray.
- FIG. 2 represents a housing with a threaded neck intended for fixing an aerosol dispenser produced according to the invention.
- FIG. 3 shows in diametrical half-section an enlarged view of the neck and of the ring obtained by the method according to the invention, after fitting of the ring, swelling of the neck and rolling of the free edge of the neck.
- the free end of the neck before rolling is shown in broken lines.
- the housing 1, illustrated in FIG. 2, is made of aluminum alloy 1050A. It is composed of a bottom 2 and a cylindrical wall 3, with a diameter of 35 mm. Its free end has been shaped into a neck 4, substantially cylindrical, of height and diameter substantially equal to 10 mm and 15 mm respectively.
- the ring 5 is made of polypropylene. It is kept fixed on the neck 4 thanks to the swelling of the neck produced according to the invention and to the rolling of the end 48 of the neck 4 leading to the formation of a rounded drink 6, that is to say having a circular toric shape, and always coated with varnish .
- the rim 6 constitutes the edge - here rounded - of the open end of the housing surrounding its orifice 7.
- the ring 5 more easily visible in the half-section of Figure 3, is made of molded polypropylene. It has a generally toroidal shape, with a central bore 52 and a cylindrical external surface 55 provided with a thread 54.
- the central bore 52 has a diameter slightly greater than the external diameter of the neck of the housing obtained by shrinking (0.1 mm on average, 0.3 mm maximum), so that the fitting of the ring can be done freely.
- the thread 54 produced on the outer surface 55 of the ring 5 is a standard thread with a triangular section.
- the ring also has a shoulder 53 produced in the central bore 52, the small recessed surface being intended to come into abutment on the shoulder 41 produced on the neck 4 of the housing at the end of fitting of the ring 5 on the neck 4.
- method for making the housing of this example comprises the conventional steps for producing an aerosol can made of aluminum alloy:
- the shrinking is carried out gradually by dabbing in several passes with form dies, the last taking the desired shape of the shoulder
- a small shoulder 41 is arranged on the neck, located at a precise distance from the upper end 49 of the neck 4.
- the height of the part 48 of the neck 4 which comes out of the central bore 52 is controlled.
- the first end 51 of the ring is molded so that it has a shape of a counter-ring 56 on which it is possible to anchor a band of guarantee of inviolability.
- the swelling is here achieved by buffering, that is to say by means of a central tool which is introduced into the orifice by forcing the free edge.
- the conical then cylindrical shape of the stamping tool requires plastic swelling increasing the diameter of the external surface 42 of the neck 4 by about 0.5 mm, over the entire length L of the cylindrical part of the neck. A strong bond is thus obtained over the entire contact surface between the neck and the bore of the ring.
- the central bore of the ring is provided with longitudinal grooves, which makes it possible to prevent any risk of loosening due to the relaxation of the stresses which occurs a certain time after the swelling.
- the end 48 of the neck 4 beyond the ring is then rolled by stamping.
- the rounded edge 6 thus formed axially blocks the ring, and above all constitutes a rounded lip, always covered with varnish, promoting the tightness of the screwed assemblies of the housing + head.
- the following smoothing operation intended to improve the surface condition of the varnish at the level of the rounded rolled edge, consists in passing a knurled wheel over said rolled edge with very little pressing force, just sufficient to smooth the rough edges created. on the varnish and plug the cavities created in the previous steps.
- the ring according to the invention is fixed securely to the neck since it resists a sliding torque greater than 20 Nm.
- This value can be compared to range of values of the unscrewing torques to be applied to sealing rings, located between 2 and 8 Nm, in particular in standard AFNOR NF H 35103 (glass rings and capsules).
- the varnish is less damaged on the inner wall of the neck, which makes the housing less susceptible to corrosion by the packaged product.
- the ring is positioned so that the distributor head is tightly fixed and is in a precise, repetitive position, with a controlled clearance between skirt and shoulder, favorable for improving the aesthetic appearance of the assembly. .
- a metal eco-refill case can be fitted with a dispensing head protected by a tamper-evident guarantee strip.
