(9) The packaging assembly 1 illustrated in this FIG. 1 comprises a tubular bottle 2 made of glass, which is adapted to receive the cosmetic product in the internal space that it defines, and is in the form of an elongate element along a longitudinal axis X. The bottle 2 extends along the longitudinal axis X between a closed bottom 3 and a neck 4 which defines an opening O for accessing the internal space of the bottle 2. A side wall 5 extends between the bottom 3 and the neck 4 of the bottle 2. The side wall 5 of the bottle 2 is connected to the neck 4 via a shoulder 6 which, in the embodiment illustrated, extends substantially in the radial direction, perpendicular to the longitudinal axis X. The bottle 2 advantageously has a wall thickness that is substantially constant along its entire length along the longitudinal axis X.

(10) In the embodiments illustrated in the figures, and as can be seen in particular in FIGS. 1 and 6, the bottom 3 of the bottle 2 has a substantially hemispherical shape centred on the longitudinal axis X. In a variant, the bottom 3 of the bottle 2 could have a flat shape, extending in a plane perpendicular to the longitudinal axis X, a conical shape centred on the longitudinal axis X or the like. In these illustrated embodiments, the bottom 3 is integral with the side wall 5 and the neck 4 of the bottle.

(11) According to another variant that is not illustrated, the bottle 2 may have an open end at the opposite end from the neck 4 along the longitudinal axis X, this open end being intended to be closed by means of a stopper attached and fastened to the bottle via complementary fastening elements provided on the bottle and the stopper, so as to form the bottom of the bottle.

(12) Furthermore, in the embodiments illustrated, the side wall 5 of the bottle 2 has a cylindrical shape, with a circular cross section. However, the side wall of the bottle could adopt a cylindrical shape with a cross section other than circular, such as a cross section that is rectangular, square, square with rounded edges, a squircle shape, ovoid or the like, without departing from the scope of the present invention. According to another variant, the side wall of the bottle could also adopt a tubular shape other than cylindrical, that is to say the shape of a tube of which the generatrix is not a straight line but, for example, a curve or a succession of segments of straight lines that form angles between one another, so as to obtain a bottle of which the side wall has a shape that is domed, in the form of an ogive, a peanut, an hourglass, a concertina, or the like. Furthermore, the side wall 5 of the bottle 2 may also have decorative reliefs or reliefs intended to make it easier to grip the bottle, such as ridges or waves, extending for example parallel to the longitudinal axis X.

(13) The neck 4 of the bottle 2 has a circular cross section and defines an outer surface 40 and an inner surface 41, opposite to the outer surface 40 in the radial direction. As can be seen in the figures, the outer surface 40 of the neck 4 of the bottle 2 is advantageously provided with fastening elements, in this case an external thread 44, adapted to cooperate with complementary fastening elements, in this instance an internal thread, provided on a closure element intended to be joined to the bottle 2 in order to close the access opening O thereof, preferably in a leaktight manner.

(14) The packaging assembly 1 also comprises a wiping member 7, 7 that is intended to be received inside the neck 4 of the bottle 2 and that defines an introduction orifice OI and a wiping orifice OE. According to known provisions, such a wiping member 7, 7 is advantageously provided when the bottle 2 is intended to be combined with an applicator 8 comprising a gripping element 9, an applicator member 11 and a stem 10 connecting these two elements, as illustrated in FIG. 6, in order in particular to scrape the stem 10 and wipe the applicator member 11 when the applicator 8 is withdrawn from the bottle 2, in order to clean the stem 10 and remove excess product loaded on the applicator member 11. In this scenario, illustrated in FIG. 6, the gripping element 9 also forms an element for closing the bottle 2, provided with fastening elements, in this case an internal thread 94, adapted to cooperate with complementary fastening elements, in this case an external thread 44, provided on the outer surface of the neck 4 of the bottle 2. When the applicator member 11 is introduced into the bottle 2, as illustrated in FIG. 6, the stem 10 extends through the wiping orifice OE and is in contact with the wiping member 7.

(15) In a variant, which is not shown, the packaging assembly 1 comprising the bottle 2 and the wiping member 7, 7 may be combined with a closure element forming a simple stopper, which does not have a stem and an applicator member, and is adapted to cooperate with the neck 4 of the bottle 2 in order to close the access opening O thereof.

(16) In one or another of the abovementioned variants, and as can be seen for example in FIG. 6, the outer surface of the closure element 9 is preferably flush with the outer surface of the side wall 5 of the bottle 2 in the radial direction when the closure element 9 closes the opening O of the neck 4 of the bottle 2. Alternatively, however, provision could be made for the outer surface of the closure element 9 to be set back from the outer surface of the side wall 5 of the bottle 2 in the radial direction when the closure element 9 closes the opening O of the neck 4 of the bottle 2.

(17) As is apparent in particular from FIGS. 3 and 4, the wiping member 7 is in the form of a generally tubular element and comprises a fastening portion PF, provided to fasten the wiping member 7 in the neck 4 of the bottle 2, said portion having a circular cross section and defining an introduction orifice OI for an applicator member 11, and a wiping portion PE that defines a wiping orifice OE on the opposite side from the introduction orifice OI along the longitudinal axis X.

(18) More specifically, and as can be seen in FIGS. 3 and 4, the fastening portion PF of the wiping member 7 has a circular cross section and comprises an inner surface 70 which defines the introduction orifice OI and an outer surface 71 provided for fastening the wiping member 7 inside the neck of the bottle 2.

(19) In the embodiments illustrated, the wiping portion PE of the wiping member 7, 7 has a wiping lip 74 in the form of a cone frustum which extends inwardly in the radial direction and the small base of which defines the wiping orifice OE. In a variant, which is not shown, the wiping lip 74 may also extend substantially along the radial direction and/or have waves about the longitudinal axis X.

(20) According to the invention, the bottle 2 is made of drawn glass, such a bottle structure and such a bottle manufacturing method making it possible to easily produce, at low cost, a bottle that is durable over time and does not use raw materials derived from petrochemicals.

(21) Furthermore, and as can be seen particularly clearly in FIG. 2, the inner surface 41 of the neck 4 of the bottle 2 has an annular bulge 42 that extends inwardly in the radial direction and is obtained by circular deformation about the longitudinal axis X of the outer surface 40 of the neck 4. Such an operation of circular deformation of the outer surface 40 of the neck 4, which causes the formation of the annular bulge 42 on the inner surface 41 of the neck 4, is particularly easy to carry out when the bottle is made of drawn glass, during a step of hot deformation of a tubular bottle parison, as will be described in more detail below.

(22) As illustrated in particular in FIGS. 3 to 5, the wiping member 7, 7 has, on the outer surface 71 of its fastening portion PF, an annular groove 72 with a shape substantially complementary to that of the annular bulge 42 formed on the inner surface 41 of the neck 4 of the bottle 2.

(23) According to the invention, the annular bulge 42 formed on the inner surface 41 of the neck 4 of the bottle 2 is designed and adapted to cooperate with and be accommodated in the annular groove 72 formed in the outer surface 71 of the fastening portion PF of the wiping member 7, 7 in order to fasten the wiping member 7, 7 inside the neck 4 of the bottle 2 by snap-fastening, or elastic push-fitting. Such snap-fastening makes it possible to keep the wiping member 7, 7 inside the neck 4 of the bottle 2 robustly, reliably and inexpensively.

(24) Advantageously, and as illustrated in particular in FIG. 2, the annular bulge 42 protrudes in the radial direction from the inner surface 41 of the neck 4 of the bottle 2 by a distance d greater than or equal to 0.3 mm, and preferably greater than or equal to 0.4 mm. In the embodiment illustrated, the annular bulge 42 protrudes in the radial direction from the inner surface 41 of the neck 4 by a distance d of around 0.4 mm.

(25) Furthermore, and still with reference to FIG. 2, the annular bulge 42 extends over a height h along the longitudinal axis X greater than or equal to 1 mm, and preferably greater than or equal to 2 mm. In the embodiment illustrated, the annular bulge 42 extends over a height h along the longitudinal axis X of around 2.4 mm.

(26) In the embodiment illustrated in FIGS. 1 to 4 and 6, the fastening portion PF of the wiping member 7 also has a collar 73 bearing on the mouth of the neck 4 of the bottle 2 and defining the introduction orifice OI situated above the opening O of the neck 4 of the bottle 2 along the longitudinal axis X. In other words, the introduction orifice OI protrudes from the opening O of the neck 4 of the bottle 2 along the longitudinal axis X, on the opposite side from the bottom 3 of the bottle 2. This bearing collar 73 makes it possible to reinforce the retention of the wiping member 7 in the neck 4 of the bottle 2 in particular in the direction of insertion of the wiping member in the direction of the bottom 3 of the bottle 2. Furthermore, such a bearing collar 73 may contribute to the tightness of the bottle 2 when the latter is combined with a closure element 9, as illustrated in FIG. 6, a sealing contact being formed between the bearing collar 73 and the closure element 9 when the latter closes the bottle 2.

(27) In a variant, and as illustrated in FIG. 5, the wiping member 7 does not have a collar bearing on the mouth of the neck 4 of the bottle 2 and defines an introduction orifice OI situated below and set back from the opening O of the neck 4 of the bottle 2 along the longitudinal axis X, in the direction of the bottom 3 of the bottle 2.

(28) The present invention also relates to a process for manufacturing a glass bottle implemented within an assembly for packaging a cosmetic product as described above.

(29) The process for manufacturing a glass bottle according to the invention implements a technique of blowing combined with drawing, the general principles of which will be described below; the term drawn glass is then used. In this manufacturing technique, the raw materials are initially weighed, then mixed and wetted. Cullet is then preferably added to this vitrifiable mixture before it is charged continuously into a melting furnace. The cullet is ground glass, for example internal waste materials, the addition of which advantageously makes it possible to lower the melting temperature of the mixture, thereby making the heating step less energy consuming. At the outlet of the furnace, the glass forms a ribbon, which is round onto a mandrel provided with a cooling system and an air blowing system. This mandrel is often inclined slightly with respect to the horizontal and set in rotational movement about its axis. This mandrel typically has a circular cross section in order to give the parison produced a corresponding circular cross section, but may also have a cross section other than circular, such as rectangular, square or ovoid, in order to give the parison produced a corresponding cross section. The glass ribbon is then wound around this mandrel until it forms a large tube which slides slowly over it. At a certain distance from this device, for example around forty metres, a drawing machine (machine provided with two rotating belts which drive the load in its movement generated by the rotation of the mandrel) continuously pulls on this tube which, over this distance, has taken on its final dimensions and reached the solidification temperature. Since the flow rate at the outlet of the furnace, or feeder, given by a calibrated orifice, is constant, it is the speed of the drawing machine and the pressure of the blowing air through the mandrel which gives the glass rod its desired outer radial dimensions, typically its diameter when the tubular parison has a circular cross section, and its desired thickness. Following the drawing machine, a cutting machine delivers the load in portions, the ends of which are recut straight and fire polished on a finishing line, in order to obtain the glass rods, which will be delivered to the conversion glassworks to create the finished products.

(30) Thus, in a first step a) of the process according to the invention, a tubular glass parison made of drawn glass is produced in the form of a tube that is open at its ends, or glass rod, which is typically cylindrical and generally has a circular cross section, but which may also have a cross section other than circular, such as rectangular, square or ovoid, with substantially constant outer radial dimensions, typically a diameter when the tubular parison has a circular cross section, and a substantially constant thickness, extending along a longitudinal axis X and having, optionally after being cut, a desired length along the longitudinal axis X. This tubular parison may, for example, be obtained from a relatively long glass rod, formed continuously, and delivered so as to obtain portions of desired length along the longitudinal axis X. The tubular parison thus obtained may directly define the side wall 5 of the bottle 2, in terms of shape and size. In a variant, this tubular parison may subsequently be reworked so as to confer the desired shape on the side wall of the bottle, as will be described in more detail below.

(31) Following partial cooling or preferably following complete cooling and reheating of the parison thus obtained, steps of shaping by hot deformation or hot shaping of the parison are carried out in order to shape the bottle with the finally desired shape. In particular, these steps of hot deformation of the tubular parison can be carried out, in one or preferably in several passes, by means of a system of wheels, in particular wheels that rotate freely or wheels that are driven in rotation about their axis, and the axis of rotation of which can be set into movement in translation in a direction perpendicular to the longitudinal axis X of the tubular parison, into movement in translation along the longitudinal axis X of the tubular parison and into rotational movement about the longitudinal axis X of the tubular parison, the latter being kept fixed along and about its longitudinal axis X. In a variant, the tubular parison can be set into rotational movement about its longitudinal axis X and the axes of the shaping wheels are set into movement in translation in a direction perpendicular to the longitudinal axis X of the tubular parison and into movement in translation along the longitudinal axis X of the tubular parison. Such a hot deformation method using mobile wheels has the advantage of leaving few traces on the visible outer surface of the finished product obtained. However, other methods for hot shaping a parison in order to obtain the finished bottle can be envisaged, for example techniques implementing shaping shells designed to enclose the tubular parison in order to give it its final outer shape.

(32) Thus, in the embodiment variant in which the bottle 2 has, at its first end, a bottom 3 integral with the side wall 5 of the bottle 2, the process for manufacturing the glass bottle according to the invention comprises a step b) during which hot deformation of a first end of the tubular parison is carried out so as to form the bottom 3 of the bottle 2. In the embodiment illustrated in FIGS. 1 and 6, the bottom 3 has a substantially hemispherical shape centred on the longitudinal axis X. In a variant, however, other shapes for the bottom 3 of the bottle could be envisaged, such as a flat shape, extending in a plane perpendicular to the longitudinal axis X, a conical shape centred on the longitudinal axis X or the like.

(33) In the embodiment variant in which the first end of the glass bottle is open and intended to be closed by means of a stopper attached to the bottle via complementary fastening elements provided on the stopper and on the first end of the bottle, the process for manufacturing the bottle according to the invention comprises a step b) during which hot deformation of the first end of the tubular parison is carried out so as to form the fastening element adapted to cooperate with the complementary fastening element provided on the attached stopper. In particular, the fastening element provided on the first end of the bottle may, for example, be formed by an internal thread adapted to cooperate with an external thread provided on the attached stopper or by a snap-fastening groove adapted to cooperate with a snap-fastening bulge provided on the attached stopper.

(34) The process for manufacturing a glass bottle according to the invention also comprises a step c) during which hot deformation of a second end of the tubular parison, at the opposite end from the first end along the longitudinal axis X, is carried out so as to form the neck 4 of the bottle 2 in the form of a tubular portion with a circular cross section having a smaller diameter than the side wall 5, which defines the access opening O of the bottle 2 and is connected to the side wall 5 via a shoulder 6, the latter extending in particular in the radial direction. Advantageously, during this step c), the external thread 44 is also formed on the neck 4 of the bottle 2.

(35) The process for manufacturing a glass bottle according to the invention lastly comprises a step d) during which circular hot deformation is carried out in the radial direction of the neck 4 of the bottle 2, at an axial abscissa situated between the shoulder 6 and the access opening O, and preferably between the shoulder 6 and the external thread 44 created on the neck 4 of the bottle 2, so as to form an annular groove 43 in the outer surface 40 of the neck 4, causing the formation of an annular bulge 42 on the inner surface 41 of the neck 4.

(36) These above-described steps b) or b) to d) may advantageously be carried out simultaneously, during a single step of hot deformation of the tubular parison made of drawn glass obtained at the end of step a). In a variant, provision may be made for these steps b) or b) to d) to be carried out sequentially, in one order or another, although step d) is preferably carried out simultaneously with step c) or after step c).

(37) Furthermore, during this phase of shaping the bottle, before, after or simultaneously with the above-described steps b) to d), it is also possible to shape the side wall of the bottle such that it adopts a cylindrical shape, in particular with a circular cross section having a desired diameter, optionally different from and in particular smaller than that of the tubular parison obtained at the end of step a). In a variant, during this phase of shaping the tubular parison by hot deformation, it is possible to shape the side wall of the bottle such that it adopts a cylindrical shape, but with a cross section other than circular, for example a cross section that is rectangular, square, square with rounded edges, a squircle shape, ovoid or the like. According to yet another variant, during this phase of shaping the tubular parison by hot deformation, it is possible to shape the side wall of the bottle such that it adopts a tubular shape other than cylindrical, that is to say the shape of a tube of which the generatrix is not a straight line but, for example, a curve or a succession of segments of straight lines that form angles between one another, so as to obtain a bottle of which the side wall has a shape that is domed, in the form of an ogive, a peanut, an hourglass, a concertina, or the like. In addition, during this phase of shaping the tubular parison, it is possible to create reliefs such as ridges or waves, for example parallel to the longitudinal axis X, on the outer surface of the side wall 5 of the bottle 2.

(38) At the end of these steps a) to d), a tubular bottle 2 made of drawn glass is obtained, which is ready to be joined to a wiping member 7.

(39) The wiping member 7 and the bottle 2 belonging to the packaging assembly 1 according to the invention may be joined particularly easily, in particular during automated assembly in the factory, and will be described with reference to FIGS. 2 to 4.

(40) In a first assembly step, illustrated partially in FIG. 2, a tubular bottle 2 made of drawn glass is provided, which is obtained and shaped in particular by means of the process described above.

(41) In a second step, a wiping member 7 having, on the outer surface 71 of its fastening portion PF, an annular groove 72 with a shape substantially complementary to that of the annular bulge 42 formed on the inner surface 41 of the neck 4 of the bottle 2 is provided.

(42) In a third step, illustrated in FIG. 3, the wiping member 7 is positioned in a centred manner on the longitudinal axis X of the bottle 2, with the wiping portion PE, and in this case the wiping lip 74, next to the opening O of the bottle, and a pushing force is applied along the arrow F, shown in this FIG. 3, along the longitudinal axis X and in the direction of the bottom 3 of the bottle 2, in order to insert the wiping member through the opening O of the bottle 2.

(43) On continuing to apply this force applied to the wiping member 7 in the direction of the bottom 3 of the bottle 2, the wiping member 7 is made to deform in the radial direction in contact with the annular bulge 42 formed on the inner surface 41 of the neck 4 of the bottle 2, until the groove 72 present on the outer surface 71 of its fastening portion PF fits over the annular bulge 42 by elastic return, in order to achieve axial retention of the wiping member 7 in the neck 4 of the bottle 2 in both directions along the longitudinal axis X, as shown in FIG. 4. Snap-fastening, or elastic push-fitting, of the wiping member 7 in the neck 4 of the tubular bottle 2 made of drawn glass is achieved, by the cooperation of the annular bulge 42 formed on the inner surface 41 of the neck 4 of the bottle 2 and the annular groove 72 formed in the outer surface 71 of the fastening portion PF of the wiping member 7.

(44) Furthermore, in the embodiment illustrated in FIGS. 1 to 4 and 6, the wiping member 7 is additionally provided with a collar 73 bearing on the mouth of the neck 4 of the bottle 2 when the annular bulge 42 formed on the inner surface 41 of the neck 4 of the bottle 2 is accommodated in the groove 72 present in the outer surface 71 of the fastening portion PF of the wiping member 7.

(45) In the embodiment illustrated in FIG. 5, the wiping member 7 does not have such a bearing collar and the wiping member 7 is hold in the neck 4 of the bottle 2 essentially by the cooperation of the annular bulge 42 formed on the inner surface 41 of the neck 4 of the bottle 2 and the groove 72 present in the outer surface 71 of the fastening portion PF of the wiping member 7.

(46) Preferably, in one or another of the embodiment illustrated, it is also possible to provide, in addition to the snap-fastening of the annular groove 72 of the wiping member 7, 7, tightened or close contact in the radial direction between the neck 4 of the bottle 2 and the wiping member 7, 7, and in particular between the inner surface 40 of the neck 4 of the bottle 2 and the outer surface 71 of the fastening portion PF of the wiping member 7, 7. In particular, and as can be seen in FIGS. 4 and 5, tightened contact in the radial direction is advantageously provided between the inner surface 41 of the neck 4 of the bottle 2 and an upper part of the outer surface 71 of the fastening portion PF of the wiping member 7 situated axially between the introduction orifice OI and the annular groove 72. In a variant or in addition, tightened contact in the radial direction may also be provided between the inner surface 41 of the neck 4 of the bottle 2 and a lower part of the outer surface 71 of the fastening portion PF of the wiping member 7, said portion being situated axially between the annular groove 72 and the wiping portion PE. In one particular embodiment, tightened contact in the radial direction is advantageously provided between the inner surface 41 of the neck 4 of the bottle 2 and the upper part of the outer surface 71 of the fastening portion PF of the wiping member 7, said portion being situated axially between the introduction orifice OI and the annular groove 72, and a clearance in the radial direction is left between the inner surface 41 of the neck 4 of the bottle 2 and the lower part of the outer surface 71 of the fastening portion PF of the wiping member 7, said portion being situated axially between the annular groove 72 and the wiping portion PE.
