Definitions

• the present invention relates to a method of placing an automatic straw extraction device in a can-type container, and its associated device.
• an automatic straw extraction device intended to equip metallic cylindrical cans of the type comprising a container closed by a crimped cover which comprises opening means constituted by a push ring intended to move towards the inside the can a pre-cut tab.
• Such an extraction device is, for example, described in the French patent published under the number 2 772 731 and comprises a straw support member constituted by a deformable elastic retaining arm, one of the ends of which is connected to a ring peripheral and the other includes means for retaining straw.
• the peripheral ring is intended to be sandwiched between the cover and more particularly its crimping groove and the upper peripheral edge of the container, while the retaining arm is tensioned before being put in place by displacement and supported. on a fixed stop secured to the peripheral ring.
• the present invention therefore proposes to resolve these drawbacks by proposing a device without a fixed stop for the straw retaining arm deformed and its implementation method.
• the method of placing in a can comprising a container closed by a cover of an automatic device for extracting a straw of the type comprising a straw support member constituted by a deformable retaining arm elastically intended to be tensioned by elastic deformation, said arm comprising a retaining tube for straw, is characterized in that it consists in tensioning said arm by direct or indirect action of the cover during coupling of said cover with said device.
• the method comprises the following preliminary steps: a- attach the straw to the retaining arm to form an intermediate sub-assembly, namely, the straw-extraction sub-assembly;
• the method consists in tensioning the retaining arm by action of the cover on a projection integral with the retaining arm, ie on the straw retained by the arm.
• the invention also relates to the straw extraction device intended to implement the method which comprises a straw support member constituted by an elastically deformable retaining arm, one of the ends of which is connected to a peripheral ring or ring annular, while the free end of the arm comprises means for retaining the straw.
• the straw retaining means are constituted by a portion of retaining tube (10).
• the device is produced in a single piece of plastic material, while the annular ring comprises a succession of deformable lips which are sandwiched peripherally during the crimping of the can between the lid and more particularly its crimping groove and the upper peripheral edge of the container opening.
• the retaining arm comprises an actuating arm intended to be activated and moved by the cover when the can is opened, while the elastic connection of the retaining arm with the peripheral ring is produced by the succession of two elastically deformable zones: a first deformation zone allowing the retaining arm to move in horizontal pivoting around a vertical pivot axis, and a second deformation zone distinct from the first deformation zone allowing the arm to move in a vertical pivot around a horizontal pivot axis.
• Figures 1 and 2 respectively illustrate in perspective the opening of a container of the metal cylindrical can type comprising the device of the invention.
• Figure 1 illustrates the closed can.
• Figure 2 illustrates the open can once the cover has allowed the straw to protrude through the opening.
• FIGS 3, 4, 5, 6 and 7 illustrate a first embodiment of the extraction device.
• Figures 8, 9, 10, 11 and 12 illustrate a second embodiment of the extraction device.
• FIGS 13, 14, 15, 16, 17 and 18 illustrate the phases of the process with the use of the first embodiment of the extraction device.
• FIGS 19, 20, 21, 22, 23 and 24 illustrate the phases of the process with the use of the second embodiment of the extraction device.
• Figure 25 is a bottom perspective view of a variant of the second embodiment of the device
• the invention relates to a method for installing an automatic straw extraction device bearing the general reference (1) intended to automatically extract when it is opened a straw (2) placed inside a container ( 3).
• the extraction device (1) is advantageously described in the particular case of cylindrical cans metal, the opening means of which are constituted in a manner known per se by a push ring (4) and a precut tab (5) also called a cover which can pivot towards the interior of the container (3) under the action of the ring to release the orifice (6) of said opening means, as shown in Figures 1 and 2. It goes without saying that the automatic extraction device according to the invention could be modified to be suitable for other types containers or other types of opening means without departing from the scope of the invention.
• the extraction device (1) intended to be used during the process of the invention comprises a straw support member (7) constituted by an elastically deformable retaining arm (8) one end of which is connected to a ring peripheral or annular ring (9). Furthermore, the free end of the arm (8) comprises means (10) for retaining the straw, which are constituted by a portion of retaining tube (10) advantageously open, to give it sufficient elasticity in order to pinch the straw.
• the extraction device is advantageously made in a single piece of plastic material, while the annular ring (9) comprises a succession of deformable lips (15) which are sandwiched peripherally during the crimping of the can between the cover (14) and more particularly its crimping groove and the upper peripheral edge of the opening of the container as shown in FIG. 6a and in FIG. 11a.
• the retaining means (10) of the straw are extended upward by a projection for deformation of the arm (11) which extends upwards.
• Said projection (11) is constituted by a cylindrical wall portion whose upper end (12) is intended to abut on the lower wall (13) of the cover (14) when it is coupled with said device, as is illustrated in Figures 6, and 16 and, of course, during the crimping of the cover, thus causing the deformation down along F of the arm (8), as illustrated in FIG. 6 and in FIG. 16.
• the retaining arm (8) does not include a deformation projection.
• the arm is deformed by direct action of the cover on the straw.
• said arm (8) comprises an actuating arm (18) intended to be activated and moved by the cover (5) when the can is opened.
• the elastic connection of the retaining arm (8) with the peripheral ring (9) is produced by the succession of two elastically deformable zones: a first deformation zone (16) allowing the retaining arm (8) to move in horizontal pivoting around a vertical pivot axis (XX '), and a second deformation zone (17), distinct from the first deformation zone (15), allowing the arm (8) to move in pivoting vertical around a horizontal pivot axis (YY ').
• the second deformation zone (17) is a deformable flat profile, but it could have any other shape and in particular that illustrated in FIG. 25.
• the retaining arm (8) extends from the peripheral ring inward substantially horizontally, at least in a plane substantially parallel to the general plane (H) of said ring (9 ).
• the retaining arm (8) forms with the general plane (H) of the peripheral ring ( 9) an acute angle (A) of between 20 and 60 degrees and, for example, 40 degrees.
• the retaining arm (8) is resiliently biased downward along F, so that, when opened, this elasticity is returned to extract the straw (2) from the opening, as illustrated in Figures 2, 6 and 11.
• the arm is placed under stress when the cover (14) is coupled with the device (1) as illustrated in FIGS. 6, 11, 16, 17, 22 and 23 by direct or indirect action of said cover on the retaining arm.
• the lower wall (13) of the cover (14) biases the retaining arm (8) in elastic preload downwards by its direct action on the end (12) of the deformation projection of the arm (11).
• the lower wall (13) of the cover (14) biases the retaining arm (8) in elastic preload downwards by its direct action on the end (20) of the straw (2) retained by the tubular retaining portion (10).
• the end (150) of the actuating arm (15) is arranged in the path of the cover (5). Also, when the can is opened, the cover (5) acts on the actuating arm (15) to rotate the assembly which it constitutes with the retaining arm (8) around the axis. (XX ') and thus place the end of the straw in the area of the opening (6), the straw immediately protruding through this opening by releasing the prestress.
• a- attach the straw to the retaining arm by inserting the straw into the retaining tube (10) to form an intermediate sub-assembly (30), namely, the straw sub-assembly (2) -extraction device ( 1).
• the sub-assembly (30) is engaged under the cover (14) and clipped with the latter by cooperation of the succession of lips (15) with the peripheral groove (31) of the cover (see FIGS. 15, 16 and Figures 21 and 22).
• the installation of the device with its straw with the cover is done with a determined relative angular orientation.
• the lower wall (13) of the latter forces the retaining arm (8) directly or indirectly downwards to place it in the preloaded position, as illustrated in Figures 6, 16 and Figures 11 and 22.
• the second deformation zone (17) is an open hollow profile, in particular in the shape of an omega, in order to give said zone an appropriate elasticity.
• the straw (2) used is advantageously a telescopic straw, flexed, that is to say which comprises a deformation accordion.
• the device may include a guide ramp (90) for the end of the straw, as shown in FIGS. 9, 10 and 25.
