Definitions
- the invention relates to the field of closure caps comprising an outer metal shell of aluminum alloy and in particular screw caps which comprise an inner insert typically made of plastic and threaded.
- These capsules are intended for capping containers, mainly glass bottles containing alcoholic beverages and especially wine or spirits.
- the invention relates more particularly to a method of manufacturing these capsules to obtain a textured appearance on the top, or head, and smooth or shiny on the "vertical" wall or skirt of the outside of the capsule.
- the aluminum alloy capping capsules are typically manufactured as follows:
- a stamping press forms blanks of capsules from a strip or sheet also called format, cut into blanks, varnished on both sides, with a typical thickness ranging from 0.15 to 0.25 mm without taking into account account varnish.
- a typical thickness ranging from 0.15 to 0.25 mm without taking into account account varnish.
- one to three stamping passes may be required.
- the invention aims to solve this problem by proposing a method that retains the initial textured appearance over the entire surface of the head of the blank, and smooth or shine over the entire height of the skirt, and this under industrially economical conditions for the bottle closure market of beverage bottles.
- the invention relates to a method of manufacturing metal caps for capping comprising:
- a step of degreasing thermally, typically at a temperature of 180 to 210 ° C, for a time of 3 to 5 minutes, or chemical in an alkaline medium, of said stamped blank, intended to typically eliminate the residues of lubricant, for forming a defatted blank that can be varnished,
- the blank has a thickness of 0.15 to 0.25 mm without taking into account the varnish.
- the draw ratio (1 - final thickness / initial thickness of the sheet or strip) is greater than or equal to 2.5%.
- it is less than or equal to 30%.
- only the face intended for the inside of the capsule is coated with a varnish before stamping and the face intended for the outside of the capsule is only after the degreasing step.
- the two faces intended for the inside and the outside of the capsule are coated with a varnish before stamping.
- the lubricant used for stamping is volatile and removed by heating.
- lubricant used for the drawing which advantageously is volatile and removed by heating, typically in a passage oven or in an oven.
- the same lubricant can be used for the two stamping and drawing steps.
- drawing and stretching steps are chained in two integrated steps, that is to say without any intermediate step and even more advantageously, they are carried out in one and the same press stroke.
- the aluminum alloy can be, but not exclusively, AA3 type 105 or AA801 type 1.
- the invention also relates to a metal closure cap manufactured by the method having one of the preceding features, and characterized in that it has a so-called "textured" appearance on the entire surface of the head or top, and a smooth or shiny appearance over the entire height of the skirt, or wall.
- Figure 1 is a schematic section of the capsule used for testing. Its diameter is 33 mm. its height H is 24 mm after stamping, 20 mm after cutting horns of anisotropy and finally 28 mm after stretching, its top or head or "top” is flat and is connected to the skirt or vertical wall A with a radius R of 5 mm.
- FIG. 2 shows, from left to right, the top of a textured capsule of patterns in parallel lines after stamping and drawing according to the invention, a view of the skirt of the same capsule after stamping and finally a view of the skirt of the same capsule after stamping and stretching where the textured appearance has disappeared to give way to a smooth or shiny appearance.
- Figure 3 shows, from left to right, the top of a textured capsule of patterns in perpendicular lines and a view of the skirt of the same capsule after stamping and stretching where the textured appearance has disappeared to give new room to a smooth or shiny appearance.
- FIG. 4 represents the roughness Ra in microns, measured in the long direction from top to bottom of the wall, for:
- Capsules only stamped, marked B obtained from the formats 0, 1, 2 and 3 above, the measurement being performed on the skirt, from top to bottom of the wall,
- the interest of the invention was therefore multiple: uniformize the thickness of the skirt over its entire height by minimizing the amount of material used, or allowing the manufacture of higher capsules without increasing the amount of material , and finally, get an aesthetic effect with a textured appearance on the top or head and smooth or shiny on the skirt or capsule wall.
- the minimum rate of stretching is justified by the fact that the latter must at least bring the thickness of the entire skirt substantially uniformly to the value of the minimum thickness locally obtained after stamping (ie 0.203 mm in the case of Figure 1).
- the latter depends on the stamping conditions (roughness of the tool, play, clamping pressure, lubrication). This minimum rate is generally considered to be 2.5 or even 3%.
- the maximum draw ratio is related to the limit of stretch before rupture, intrinsic to the alloy, which must not be exceeded during the drawing, or calibration, of the bottom of the skirt, the thickest zone (of 0.236 mm according to Figure 1).
- the industrially acceptable stretching limit is 40%. A maximum draw ratio of approximately 30% is then obtained.
- the diameter of the matrix was 33.68 mm and its radius 2.5 mm.
- the lubricant was of the type known as KLUBERFOOD NH 1 16-180.
- the blanking pressure was adjusted to obtain a cup without creases.
- This step made it possible to manufacture cups or capsules as schematically represented in section in FIG. 1, and marked B in FIG. Drawing step
- the second stretching pass was made on the cups previously stamped according to step 1 above, with the following features tools:
- gambling% being the drawing ratio, here 28.6%, ie 0.286
- This step made it possible to manufacture drawn stretched capsules according to the invention, referenced C in FIG.
- the surface roughness Ra has been used to quantify the criterion of brightness, the latter being all the brighter in that the surface is smooth and thus the roughness is low.
- the roughness of the capsule, stamped and stretched according to the invention was compared with the roughness of the capsule only stamped (according to the prior art), and finally with the initial roughness of the metal in strip or sheet or starting format at flat, before shaping the capsule.
- Roughness was measured on flat formats and on the wall or skirt of the capsules from top to bottom of the wall.
- Figure 2 shows a capsule stamped in the center and two capsules stamped and stretched on both sides, with the texture 2.
- FIG. 4 compares the roughness of the flat format A with the walls or skirts of the capsules A of the prior art and with those of the capsules C according to the invention.
