Definitions
- the present invention relates to a consumable product package which is provided with a wall and provided with an orifice.
- It relates more particularly to a device for opening and closing such a package.
- This package is for example a can, which means a substantially cylindrical container, usually double-reduction steel or aluminum, for containing a consumable product such as a liquid drink.
- a consumable product such as a liquid drink.
- the terms “inner” and “outer” respectively refer to parts of a part directed towards or located inside the package, and directed towards or located outside the package.
- An example of packaging for the prior art and the invention is a bobbin.
- An example of a consumable product is a liquid drink.
- the lower end of the bobbin is closed, and its upper face is a cup whose flat portion comprises a cap, and a tab which is attached to the cup by a point of attachment located near the lid.
- This tongue by a lever movement relative to this point of attachment, presses on the lid so as to tear a pre-cut portion of the periphery of the lid.
- the lid by tearing, thus creates an orifice through which the liquid contained in the can can flow outside, for example to be consumed.
- the lid is thus folded inside the bobbin, held attached to the cup by the not torn part of its periphery.
- Such a can has the disadvantage that it can not be closed once opened. Liquid can escape from the bobbin if it is spilled. Foreign objects (insects, dusts) can also contaminate the liquid by penetrating through the hole of the cup. In addition, if the liquid is gaseous, there is no more gas present in the drink after a few hours. These disadvantages in particular require the user to consume the entire contents of the can in a short time after opening.
- This device 1 comprises a body 2 in one piece, made of molded material, which comprises a plate 20 provided with a first hole 30 placed in front of the orifice 13 of the cup 15 and fixed on the edge 19 of this orifice sealingly, and a hatch 40 articulated to the plate 20 opening towards the inside of the can and adapted to cover this first hole 30 in the closed position.
- This device 1 further comprises an arm 50 connected to this hatch 40 and which cooperates with locking means in a position such that it keeps the hatch 40 in the closed position.
- This device 1 further comprises a cover 80 separate from the body 2 and the arm 50, and which is provided with a safety cover 100 (shown in transparency) which must be broken during the first opening of the hatch 40 and which forms part of the blocking means. Thus, if this safety seal is intact, it is guaranteed that the package has never been opened before.
- the bobbin is thus sealed between two openings of the hatch 40 of the device. It can therefore be consumed in several times with a preservation of its contents between two openings of the can.
- this content is a carbonated beverage
- the gas released by the beverage between two openings remains inside the can, and the gaseous nature of the drink is preserved until the next opening of the can, at the consumer satisfaction.
- the invention aims to remedy the drawbacks mentioned above by proposing a package equipped with an opening and closing device that allows to open and close at will this package, which is perfectly sealed, and which is easily maneuverable by the user even when it is first opened.
- the hatch is provided with a second hole which communicates the inside and outside of the package
- the arm is provided with a seal which closes the second hole of sealingly when the arm cooperates with the locking means so that in the closed position the device closes the package sealingly, the seal releasing the second hole when the arm is disengaged from the locking means and the angle ⁇ pivoting of the arm relative to its closed position is greater than a threshold angle ⁇ strictly positive.
- the packaging can be initially opened without difficulty, even when it contains in particular gas under pressure, for example when it contains a carbonated beverage.
- the gas can escape (degassing) through the second hole so that the gas pressure on the hatch is reduced, which allows the tilting of the hatch towards the inside of the package without effort.
- degassing occurs only when the arm has already pivoted by a minimum threshold angle avoids accidental degassing by deformation of the cup under the effect of the pressure of the gases contained in the packaging.
- the locking means further comprise a snap mechanism of the arm on the plate.
- the locking of the arm, and therefore of the opening and closing device, in the closed position is reinforced, which makes it possible to avoid a accidental unlocking of the arm by deformation of the cup under the effect of the pressure of the gases contained in the container.
- the plate is fixed on the edge of the orifice of the wall by snapping.
- the plate bears essentially on the inner face of the wall.

- FIG. 17 is a sectional view of the cup and the opening and closing device according to the plane II-II of Figure 16.
- FIGS 1 to 4 show the device 1 for opening and closing according to the invention mounted on a cup 10 of a can (not shown).
- the cup 10 is substantially circular, with a substantially flat wall 15 surrounded by a peripheral rim 12.
- the peripheral rim 12 of the cup is for example identical to the rim of a standard bobbin cup, so that the cup 10, a equipped with the device 1, can be mounted during manufacture on any bobbin.
- the wall 15 of the cup 10 advantageously has at least one relief 150, which will be described later.
- the wall 15 of the cup 10 has an orifice 13 delimited by an inner edge 19 (visible in FIGS. 15A and 15B).
- the orifice 13 has an oblong shape and extends radially from the center of the cup 10 to near the flange 12.
- FIG. 1 and Figure 2 show the device 1 in the partially open position.
- the device 1 comprises a body 2, which comprises a plate 20 which has at its center a first hole 30 delimited by an edge 25 of the plate 20.
- the body 2 is also shown in FIG. 7 and FIG. also a hatch 40, the body 2 being integral, that is to say that the hatch 40 forms a continuous assembly with the plate 20.
- the body 2 is manufactured by molding in a single block, this which is a faster industrial solution and less expensive than if the hatch 40 was manufactured separately from the plate 20.
- the body 2 is for example made of polymer.
- the hatch 40 is hinged to the plate 20 by a flexible web 41 molded, located on the circumference of the plate 20.
- the sail 41 thus forms a hinge.
- the hatch 40 comprises a base 42 around the periphery 47, in the middle of which is mounted a cylindrical wall 45.
- Figure 4 shows the hatch 40 in the closed position. The veil 41 is then completely folded.
- the plate 20 has around the first hole 30 a first seal 91 at the interface with the hatch 40.
- This first seal 91 extends all along the circumference of the radially inner face of the edge 25 of the plate 20 which surrounds the first hole 30 over at least a portion of the height of this face.
- the radially outer face of the cylindrical wall 45 deforms the first seal 91, which ensures the seal between the hatch 40 and the plate 20 at the interface between the cylindrical wall 45 and the edge 25 of the plate 20.
- FIG. 5 is an enlargement of a part of FIG. 4, detailing the interlocking of the hatch 40 and the plate 20.
- the hatch 40 has two holes, which are the second holes 70. These holes establish a communication between the inside and the outside of the package. They thus allow the escape of the gas possibly contained in the package, even when the hatch 40 and the plate 20 are nested).
- a second hole 70 covers the case where this second hole 70 consists of two second holes 70 or more.
- the arm 50 is provided with a seal 57 which is able to close these second holes 70 (see detailed description of such a seal 57 below).
- a seal 57 which is able to close these second holes 70 (see detailed description of such a seal 57 below).
- This support between the hatch 40 and the plate 20 makes it possible to prevent the hatch 40 from passing through the first hole 30, and makes it possible to stabilize the interface between the cylindrical wall 45 and the first seal 91.
- the periphery 47 of the hatch 40 bears on its entire length on the lower face 27 of the plate 20.
- This contact between the periphery 47 and the lower face 20 contributes to the sealing at the interface between the hatch 40 and the plate 20.
- the lower face 27 has a seal on which the periphery 47 presses when the hatch 40 is in the closed position, which reinforces the étanc éotti at the place of this contact.
- This seal is for example an extension of the first seal 91, as shown in Figures 2, 4, and 5.
- a latching wall 129 extends perpendicularly to the upper face 26, and extends circumferentially substantially all around the first hole 30, with the exception of the side on which the central sleeve 81 of the cover 80 is open. When the plate 20 is positioned on the wall 15 of the cup 10, the wall 129 fits into the orifice 13.
- the latching wall 129 comprises, on its radially outermost face, a first bead 295 which extends circumferentially all along this latching wall 129.
- the positioning of the latching wall 129 and the thickness (in radial direction) of the first beads 295 is such that when the latching wall 129 is pushed into the orifice 13, the latching wall 129 deforms radially towards the center of the orifice 13 when the inner edge 19 of the wall 15 pushes the first beads 295.
- the plate 20 is fixed on the wall 15 of the cup 10 by snap-fitting by means of the latching wall 129.
- latching wall 129 extends substantially all along the inner edge 19 allows a rigid assembly of the plate 20 on the cup 10.
- the latching wall 129 extends beyond the first beads 295, perpendicular to the upper face 26, by an extension which comprises a second bead 298, which extends substantially the entire length of this extension around the first hole 30.
- This extension is located slightly more towards the first hole 30 than the rest (base) of the ratchet wall 129, so as to fit freely into the orifice 13 (FIG.
- the upper face 26 comprises, over its entire circumference, a second groove 292, which surrounds the sealing wall 129.
- a second seal 92 is housed in the second groove 292 of the upper face 26 and a portion 925 of the second seal 92 protrudes outside. of the second groove, so that the portion 925 comes into contact with the inner face 17 when the plate 20 is fixed on the cup 10.
- the contact zone between the inner face 17 and the seal 92 which bears against this Completely surrounds the orifice 13.
- a seal which helps to prevent the liquid contained in the bobbin from flowing out.
- the content of the can is a gaseous liquid
- the gas tends to press the plate 20 against the inner face 17 of the wall 15.
- the pressure exerted by the inner face 17 on the second seal 92 then increases, which tends to improve the seal between the plate 20 and the wall 15.
- the second seal 92 is a ring whose cross section has substantially the shape of a W.
- the ends of the two outer branches of the W each form an outer lip 921, which surround an internal lip 922 (part internal portion of the W) which is less than the outer lips 921.
- the two outer lips 921 and the inner lip 922 constitute the portion 925 of the second seal 92 which protrudes from the groove 292.
- the second seal 92 is also visible in FIG. 10 and FIG.
- the inner lip 922 also crushes against the inner face 17, which further improves the seal between the plate 20 and the wall 15.
- the second seal 92 is shown in non-deformed condition.
- An annular seal as described above having a cross-section in W with two lips able to act as a suction cup when said annular seal is pressed against a flat surface, and framing a third lip, can also be used to ensure the sealing of a reclosing system different from the system object of the present invention, even not including a cap as described below.
- the second seal 92 may have a cross section having substantially the shape of a V.
- the assembly consisting of the body 2, the first seal 91, and the second seal 92 can be manufactured by bi-injection of a rigid polymer constituting the body 2 and a softer elastomer constituting these seals 91, and 92.
- the device 1 also comprises an arm 50, visible in the figures
- arm 50 comprises a bar 54 which terminates at one end by a handle 56 and has at the other end a circular rod 53.
- the hatch 40 (FIGS. 1, 2 and 7) comprises a clamp 43 which extends perpendicularly from the base 42 of the hatch 40 and is surrounded by the cylindrical wall 45.
- the rod 53 snaps into the clamp 43 so as to form a pivot joint along an axis parallel to the axis of pivoting of the hinge formed by the web 41.
- the width of the bar 54 of the arm 50 (dimension in the direction of this axis) is smaller than the width of the first hole 30 of the plate 20, so that the bar 54 can pass freely through the first hole 30.
- the rod 53 is embedded at each of its ends in one of the two branches 58 of a fork which extends the bar 54.
- This fork has on its lower face, that is to say its face which is directed towards the wall 15 of the cup 10 when the hatch 40 and the arm 50 are in the closed position, a seal 57.
- the shape of the branches 58 is such that their underside describes a portion of a cylinder centered on the axis of rotation (axis of symmetry) of the rod 53.
- This seal 57 covers the entire underside of each of the two branches 58 of this fork, so that the seal 57 is able to cover the second hole 70 of the hatch 40 when the hatch 40 and the arm 50 are in the closed position.
- the second hole 70 is in fact constituted by two second holes 70 located laterally on the side and other than the clamp 43.
- each branch 58 of the fork covers one of the second holes 70.
- the clamp 43 has reinforcements, for example ribs, to strengthen the pivot articulation with the rod 53 and prevent separation of the rod 53 from the clamp 43.
- the arm 50 is for example made of polymer, by molding, which minimizes the cost of production per unit.
- the arm 50 is adapted to be snapped directly onto the plate 20 by means of a latching mechanism.
- the bar 54 of the arm 50 has a slot 59 which passes through the bar 54 along an axis perpendicular to the direction in which this bar extends (from the handle 56 to the circular rod 53) and perpendicular to the axis of rotation of the circular rod 53.
- the wall 129 has a snap protrusion 1299 which extends perpendicular to the upper face 26 of the plate 20. This snap protrusion 1299 is located opposite the slot 59 when the arm 50 is snapped onto the hatch 40 and is close to its closed position, so that when the arm 50 is folded closed, the snap protrusion 1299 is housed and locked in the slot 59, as shown in Figure 8.
- the slot 59 may not be through, and open only on the lower face of the arm 50, that is to say its face which is directed towards the wall 15 of the cup 10 when the hatch 40 and the arm 50 are in the closed position.
- This snap mechanism contributes to keeping the arm 50, and therefore the hatch 40, in the closed position.
- the device 1 also comprises a cover 80, which is distinct from the body 2 and the arm 50.
- the cover 80 has a curved shell shape, with a concave face 85 and a convex face 86 ( Figure 5 and Figure 12).
- the cover 80 is bordered by a flange 87, and has tabs 88 which extend from the concave face 85 substantially perpendicular to it.
- the cover 80 is positioned on the outside face 16 of the wall 15 of the cup 10 and assembles on the plate 20 via the tabs 88.
- the ends of the tabs 88 have, on their radially internal face, a rib 888 which snaps into engagement with the second bead 298 when the cover 80 is fixed on the plate 20, so as to secure the cover 80 on the plate 20 (FIG. and Figure 14).
- the tabs 88 form an almost continuous wall around the central sleeve 81, which allows rigid attachment of the cover 80 to the plate 20.
- the cover 80 has the shape of a U.
- the center of the cover 80 is a U-shaped hole, open on one side.
- This hole is delimited by a central sleeve 81 which extends from the convex face 86, beyond the concave face 85, substantially perpendicular to it.
- the width of this central sleeve 81 is substantially equal to that of the first hole 30 of the plate 20, and when the cover 80 and the plate 20 are assembled, the central sleeve 81 is substantially in alignment with the edge 25 of the first hole. 30, with the exception of the side on which the central sleeve 81 is open. This side is the one below which the web 41 is located.
- the arm 50 is able to fold until the upper face of the arm 50 is in alignment with the convex face 86 of the cover 80 and fills the space at the center of the cover 80 (as illustrated in FIG. ) except the top of the U. No part of the device 1 therefore exceeds above the rim 12 of the cup 10, which provides minimal additional space compared to a can of the prior art.
- the cover 80 is for example made of polymer, by molding, which minimizes the cost of production per unit.
- the snap fit of the plate 20 on the cup 10 and the cover 80 on the plate 20 can be performed as described below, with reference to Figures 11 to 13.
- the latching wall 129 (see description above) is replaced by first tabs 29 and by second tabs 28.
- the plate 20 comprises, on its upper face 26, first lugs 29, which are located around the first hole 30 and which extend perpendicularly to the upper face 26.
- the first lugs 29 are located along a shape path identical to the orifice 13 and slightly smaller dimension, so that when the plate 20 is positioned on the wall 15 of the cup 10, the first tabs 29 fit into the orifice 13.
- Each of the first tabs 29 has, on its radially outermost face, a bead 295 which extends circumferentially along these first tabs 29.
- the positioning of the first tabs 29 and the thickness (in the radial direction) of the beads 295 is such that when these first lugs 29 are pushed into the orifice 13, the first lugs 29 deform radially towards the center of the orifice 13 when the internal edge 19 of the wall 15 pushes the beads 295.
- the plate 20 is fixed on the cup 10 by snap-fitting by means of the first legs 29.
- the first tabs 29 are distributed over the plate 20 over the entire circumference of the orifice 13, so that this latching is distributed substantially uniformly over the entire circumference.
- the distance between the upper face 26 (opposite to the lower face 27) of the plate 20 and the beads 295 is equal to the thickness of the wall 15, so that after this snap-in, the upper face 26 is held in position. bearing on the inner face 17 of the wall 15 by the beads 295.
- the cover 80 has tabs 88 which extend from its concave face 85 substantially perpendicular to it.
- lugs 88 snap onto second lugs 28 of the plate 20, which extend from the upper face 26 of the plate 20 through the orifice 13.
- the ends of the lugs 88 have, on their radially inner face, a rib 888, and the snap of these ribs 888 with the second legs 28 is at the level of ends of these second legs, which have a tooth shape ( Figure 12).
- the tabs 88 are therefore a means of securing the cover 80 on the plate 20.
- the first lugs 29 and the second lugs 28 are distributed alternately on the plate 20 all around the first hole 30, this distribution of the second lugs 28 ensuring that the latching between the hood 80 and the plate 20 is distributed substantially uniformly all around the first hole 30.
- the tabs 88 are of lower height than that of the flange 87 so that when the tabs 88 and the second tabs 28 are snapped, the flange 87 presses on the upper face 16 of the cup 10, which locks and stabilizes the assembly between the cover 80 and the body 20.
- a region (around the orifice 13) of the wall 15 of the cup 10 is sandwiched between the cover 80 and the plate 20.
- the arm 50 is adapted to be snapped directly onto the plate 20 by means of a latching mechanism.
- the bar 54 of the arm 50 has a slot 59 which passes through the bar 54 along an axis perpendicular to the direction in which this bar extends (from the handle 56 to the circular rod 53) and perpendicular to the axis of rotation of the circular rod 53.
- the slot 59 may not be through, and open only on the lower face of the arm 50, that is to say its face which is directed towards the wall 15 of the cup 10 when the hatch 40 and the arm 50 are in the closed position.
- This snap mechanism contributes to keeping the arm 50, and therefore the hatch 40, in the closed position.
- the cover 80 is provided with a tongue 100, visible in Figures 3 and 4, which show the device 1 before its first opening.
- the tongue 100 is substantially in the extension of the convex face 86 of the cover 80 and covers the bar 54 of the arm 50, leaving free the handle 56.
- the tongue 100 covers, partially or completely, the central sleeve 81 (that is, that is, the U-shaped central region of hood 80).
- the tongue 100 is connected to the cover 80 by a fastening system.
- This attachment system is intended to be irreversibly broken at the first opening of the device 1.
- the attachment system consists of four links 104 distributed around the perimeter of the tongue 100, each establishing a bridge between the edge of the tongue 100 and the central sleeve 81 which this edge is separated by a thin space.
- the tongue 100 and the four links 104 are for example made of polymer, by molding in one piece with the cover 80, which minimizes the cost of production per unit.
- the tongue 100, the links 104 connecting the tongue and the cover 80, and the attachment system therefore constitute a safety seal which, if intact, ensures that the bobbin has never been opened before.
- the safety cap is part of the locking means of the arm 50 in the closed position.
- the arm 50 is lifted by means of the handle 56, thus starting to break the links 104 (when the arm is in the open position, all the links 104 will be broken and the tab 100 will be completely detached, and will become useless).
- the seal 57 is slid onto the second hole 70.
- the seal 57 extends along the lower face of each of the two branches 58 and the lower face of the arm 54 so that this seal 57 is able to cover the second hole 70 from the position of the arm 50. closed position (that is to say substantially parallel to the hatch 40) to the position of the arm 50 where the arm 50 has rotated by an angle ⁇ which is equal to a threshold angle ⁇ 0 strictly positive.
- the angle ⁇ is the angle measured around the axis of rotation of the rod 53 between the arm 50 in the closed position and the arm 50 in this given position (see FIG. 6B).
- the arm 50 is in the open position.
- the seal 57 then no longer covers the second hole 70, and any gas contained in the can can begin to escape while the hatch 40 still closes almost completely the first hole 30.
- the pressure of the gas on the face lower hatch 40 is reduced, which allows the tilting of the hatch 40 to the inside of the bobbin with the arm 50 without much effort.
- the sliding movement of the seal 57 of the arm 50 relative to the second hole 70 allows a clearance and a closure of the hole 70 without difficulty for the user, even in the case where the gas pressure inside the the bobbin is high.
- the threshold angle ⁇ 0 is for example greater than 25 °, which prevents accidental degassing of the bobbin in case of slight pivoting of the arm 50 from its closed position (by the user, or by deformation of the plate 20 and hatch 40).
- the threshold angle ⁇ 0 is for example greater than 30 °.
- the threshold angle ⁇ 0 is not too high so that at the beginning of the degassing, the tongue 100 (or more generally the safety seal) is still partially attached to the cover 80, which protects the user from possible projections of the content of the bobbin through the second hole 70.
- the bar 54 of the arm 50 comprises two lugs 52 (visible in FIG. 6A) which extend laterally from this bar 54. These lugs 52 are intended to be housed in grooves 82 of the body 80 which extend from the convex face 86 along the central sleeve 81, perpendicular to this face. When the lugs 52 are housed in the grooves 82, the handle 56 of the arm 50 bears against the convex face 86, and the hatch 40 is thus locked in the open position.
- the grooves 82 and the lugs 52 therefore constitute means for locking the arm 50 in the open position. Other means for locking the arm 50 in the open position can be envisaged.
- the width (dimension in the direction of the pivot axis of the hinge formed by the web 41) of the handle 56 of the arm 50 is wider than the width of the central sleeve 81, which prevents the arm 50 from falling into the inside the bobbin, and allows a subsequent easy closure of the bobbin.
- the grooves 82 are located so that when the lugs 52 are housed in the grooves 82, the arm 50 is almost perpendicular to the plate 20, which ensures maximum opening of the hatch 40 (for example the grooves 82 are located at 1/3 closest to the top of the U (hole of the central sleeve 81), the flow of liquid through the sleeve 81 is therefore optimal.
- the first hole 30 has an oblong shape, substantially identical to the shape of the orifice 13 of the cup 10 and of smaller size. This shape emerges, in front of the arm 50 (the region of the top of the U-shaped central sleeve 81, the closest to the rim 12 of the cup) when the arm 50 is in the open position, a sufficient portion of the central sleeve 81 for allow the liquid contained in the can to flow at a flow rate suitable for consumption by a user.
- the seal 57 of the arm 50 covers the second hole 70 when the arm 50 is in the open position, which avoids pollution of the second hole 70.
- the arm 50 pivots about the axis of symmetry of the rod 53, and the seal 57 slidably covers the one or more holes 70, so that both the first hole 30 and the second hole or holes 70 are sealed again (FIG. 4).
- the hood 80 thus leaves the arm 50 cleared.
- the central sleeve 81 has on its opposite faces (the two sides of the U) two notches 812 which protrude slightly from the central sleeve 81 and extend in direction of each other. These notches 812 are located near the convex face 86 ( Figure 2 and Figure 3), so that when the arm 50 is folded as described above or before its first opening ( Figure 3 and Figure 4), the bar 54, whose width is just smaller than that of the central sleeve 81, is beyond (below) the notches 812 and is snapped therewith.
- the notches 812 are for example located closer to the open side of the U (above the web 41), so that the effort required to disengage the arm 50 of the notches 812 is maximum.
- the hatch 40 and the arm 50 are thus locked in the closed position by means of the notches 812 integral with the cover 80, which constitute means for locking the arm 50 in the closed position. These locking means are also used before the first opening of the device 1 (see above), together with the safety cap.
- the locking means may further comprise a snap mechanism of the arm 50 on the plate 20, as described above.
- the locking means can be located only on the body 2 and the arm 50, as described above (snap of the arm 50 on the plate 20).
- a ratchet wall 129 extends circumferentially substantially all around the first hole 30, except for the side on which the central sleeve 81 of the cover 80 is open, to allow the passage of the bar 54 of the arm 50 when the arm 50 is folded (device in the closed position).
- the central sleeve opposes a strong resistance to this snap, because the latch wall 129 prevents a spacing of the two branches of the U of the central sleeve 81 which rest on the end faces 127.
- the locking of the device 1 according to the invention in the closed position is therefore more efficient.
- the base 42 of the hatch 40 is cup-shaped, curved towards the inside of the package, and the second hole or holes 70 are located at the bottom of this bowl ( Figure 2 and Figure 4).
- the liquids possibly present on the base 42 can be evacuated by this or these second holes 70 before the closure of the device 1.
- a bobbin can be reopened and closed tightly as often as desired, which avoids the loss of the contents of the can, and allows the consumption of this content in several times without loss of its properties between two consumptions.
- the assembly of the three elements constituting the device 1 is done by a simple succession of joints: the plate 20 of the body 2 snaps onto the inner edge 19 of the orifice 13 of the cup 10. Then, once the hatch 40 of the body 2 folded towards the plate 20, the arm 50 snaps onto the hatch 40 by passing the bar 54 of the arm 50 through the first hole 30 of the plate 20. once the arm 50 folded against the outer face 16 of the cup 10, the cover 80 snaps onto the plate 20, the arm 50 being in the center of the U formed by the cover 80.
- the device 1 can be easily manufactured and assembled on a bobbin, and for a minimum cost.
- the device 1 can be manufactured and assembled on a wall of any package to form a package according to the invention.
- the wall 15 may be flat or curved.
- the inventors have found by carrying out tests that the seal between the device 1 and the can is improved when the wall 15 of the cup 10 has at least one relief 150 in the vicinity of the hood 80. Indeed, the force exerted on the lever 50 during closure of the device 1 produces forces on the wall 15 which tend to bend it. When the wall 15 is plane without reliefs, it can then, in certain configurations, occur a leakage at the interface between the wall 15 and the plate 20.
- the reliefs 150 cover part of the surface of the wall 15 around the cover 80 and are arranged symmetrically with respect to the longitudinal axis A of the device 1 (that is to say the axis extending in the longitudinal direction arm 50).
- the reliefs 150 cover substantially the entire surface of the wall 15 around the cover 80.
- the reliefs 150 comprise disjointed bosses 151 arranged symmetrically with respect to each other on each side of the axis A, and at least one depression 152 symmetrical with respect to the axis A and intersected by this axis. and located between the bosses 151.
- the rigidity of the wall 15 is thus improved.
- the reliefs 150 comprise two bosses 151 and two depressions 152, as shown in FIG. 15A.
- Each boss 151 has a crescent-shaped shape whose convex side follows the peripheral rim 12 of the cup 10, and whose concave side follows the radially outer edge of the cover 80 and the handle 56 of the arm 50.
- Each boss 151 s substantially extends in the direction of the axis A and rises above the wall 15, i.e. in the same direction as the peripheral flange 12 (towards the outside of the can).
- the bosses 151 do not meet at the region around the handle 56 (the device 1 being in the closed position), so that they are separated by a space cut by the axis A.
- the two oblong depressions 152 curved, which extend vertically opposite bosses 151 (towards the inside of the can).
- One of the depressions 152 extends substantially from one boss 151 to the other boss 151.
- the reliefs 150 comprise two bosses 151 and a depression 152, substantially square shape.
- the configurations of the reliefs 150 as shown in FIGS. 15A and 15B optimize the rigidity of the wall 15.
- each boss 151 and the depth of each depression 152 is at most equal to 0.5 mm.
- the stresses generated in the cup are minimized.
- the reliefs 150 are ribs 156 and stampings 159.
- Ribbing is a local deformation of the wall 15 out of the plane in which this wall 15 extends, without variation of its thickness. In a sectional plane of the wall perpendicular to the direction in which the ribbing extends, the ribbing thus has the shape of a wave.
- Forging is a local decrease in the thickness of the wall 15 in its plane, by crushing (in this case, the term stamping also covers the case where this local decrease in thickness is achieved otherwise than by crushing, for example by molding).
- the ribs 156 consist of two rectilinear segments, symmetrical with respect to the longitudinal axis A, each segment joining two points located near the peripheral rim 12 of the cup.
- the ribs 156 diverge from the peripheral rim 12 so that their extensions (the lines carrying these ribs 156) do not cut the orifice 13, which is therefore between these extensions.
- the ribs 156 do not extend in the region of the cup 15 covered by the cover 80.
- the dies 159 consist of a first stamping 1591 which runs along the peripheral rim 12 and is thus circular here, and in a second stamping 1592 on the edge of the orifice 13.
- FIG. 15D is a section of the cup 10 of FIG. 15C from the orifice 13 to the peripheral rim 12, and shows one of the ribs 156 and the two stampings 159.
- the tests carried out by the inventors show that the rigidity of the wall 15 is optimized in the case where the reliefs are the ribs 156 and stampings 159 described above and shown in FIGS. 15C and 15D.
- One or more other ribs on the wall 15 are possible, instead of or in addition to the ribs 156.
- the wall 15 may have a circular ribbing that runs along the peripheral rim 12.
- the wall 15 may also have an oblong ribbing which consists of an oblong curve which at least partially surrounds the orifice 13 extending at a substantially constant distance d 0 from the latter. For example, this distance is of the order of 5 mm.
- This oblong ribbing also at least partially surrounds the cover 80, and does not extend in the region of the cup 15 covered by the cover 80.
- this oblong ribbing completely surrounds the orifice 13.
- this oblong ribbing surrounds the orifice 13 with the exception of the end.
- the orifice 13 closest to the peripheral rim 12 that is to say that oblong ribbing begins at a first point near the peripheral rim 12, bypasses the orifice 13 over the greater length of its periphery, and extends to a second point near the peripheral flange 12, this first point and second point being symmetrical with respect to the longitudinal axis A.
- This oblong ribbing does not intersect the ribs 156 if the ribs 156 are present.
- the sealing between the device 1 according to the invention and the wall 15 of the package on which is fixed this device 1 is improved when the wall 15 has, in the vicinity of the hood 80 of the device 1, at least one relief 150. Indeed, the rigidity of the wall 15 at the device 1 is thus increased.
