    专利说明:

    The present invention relates to pressurized flasks, also called aerosol flasks, whose container is made of plastic material.
    The application US 2014/0209633 discloses an aerosol bottle comprising a plastic container whose neck has a flange for fixing a closure cup of the container equipped with a dispensing valve. The body of the container has, over a major part of its length, a constant outer section, cylindrical of revolution. US 2007/0278253 discloses an aerosol flask whose neck connects to an upper part of the body may have various profiles in longitudinal section. In particular, the body of the bottle is made with a hemispherical bottom, surmounted by a portion which has a slightly concave profile to the outside in longitudinal section. The upper part of the body, under the collar, can be frustoconical or hemispherical. The bottom is received in a base that provides a vertical seat. In variants, the bottom is made with lobes. When the body has a frustoconical portion, it remains relatively short. US 2012/0261439 and US 2004/0149781 describe aerosol flasks whose upper part of the container body is rounded convex outwardly. WO2014 / 116904 A1 discloses an aerosol flask whose neck has a crystallized portion. The body of the bottle is made with a cylindrical shape of revolution. The transition with the neck presents a rounded profile. The bottom of the bottle can be hemispherical. In general, a pressurized bottle made of plastic must be able to withstand a service pressure of generally a few bars, because of the presence of a gas under pressure inside. This resistance must be checked at a relatively high temperature, in order to guarantee safety during use.
    Moreover, the bottle can be filled under vacuum, which also imposes a resistance to collapse ("squeeze" in English) when the vacuum is at its maximum, before the filling of the gas begins.
    The bottle must finally be resistant to shocks, especially to falls at different temperatures. The bottle must also be easy to decorate by the methods used in the field of packaging (labeling, screen printing ...) The invention aims to provide a bottle satisfactorily satisfies all of these constraints. The invention responds to this need by means of a pressurized bottle comprising a plastic container comprising: a body, extending along a longitudinal axis, a neck integral with the body, characterized in that the body has a portion of substantially frustoconical, more frustoconical shape of rectilinear generatrix, extending over more than one third of the total height of the container, better on more than half, even better on at least two thirds.
    Such a pressurized bottle has satisfactory mechanical strength, because the frustoconical shape proves to have an excellent compromise between the resistance to the operating pressure and the resistance to crushing due to the evacuation.
    In addition, the bottle can be easily provided with a label to decorate it and can be easily made if desired, with a background allowing it to rest stably on a horizontal flat surface without having to bring a base.
    By "substantially frustoconical", it should be understood that the outer surface of the body deviates from a rectilinear rectilinear geometric reference surface of a maximum deflection f, measured perpendicular to this surface, of plus or minus 1.7% Lgen, where Lgen is the total length of the frustoconical portion measured along a generator. By "straight frustoconical portion" means a frustoconical portion whose generator is a straight line.
    Preferably, the container has a bottom arranged to allow it to rest stably vertically on a horizontal flat surface. Preferably, the bottom has a concave recess downwards. This recess may be delimited on part of its height by a frustoconical wall. The bottom of the recess may be curved or flat and perpendicular to the longitudinal axis of the container, to define the housing area of the injection point. The bottom is preferably arranged, in particular with the aid of the aforementioned frustoconical wall, to allow a good positioning of the dip tube during the introduction of the valve.
    The largest outside diameter of the neck is preferably between 34.7 mm and 51 mm. The smallest outside diameter of the neck is preferably between 15 and 28.7 mm. The distance between the planes where the largest and the smallest outside diameter are measured is preferably between 1.5 and 11.5 mm.
    The neck may comprise two rings defining an annular groove between them. One of the neck rings advantageously serves to crimp a dispensing valve cup and the other ring, located under the first, can be used to transport the container on the manufacturing lines and / or filling.
    Preferably, the thickness of material at the wall of the container at the base of the neck is greater than that along said substantially frustoconical portion. More preferably, the thickness of material at the edge of the recess of the bottom wall where the container rests on the support surface is greater than that of said substantially frustoconical portion. This can contribute to strengthening the impact resistance, while saving the material taking advantage of the intrinsic strength conferred by the frustoconical portion. The thickness of material along the portion of substantially frustoconical shape is preferably constant, for example between 0.6 and 1.2 mm for PET.
    The container may be PET, PEN, PCT, PCR or organic PET, or mixtures thereof.
    The ratio S2 / S1, where S2 is the outer section of the portion of substantially frustoconical shape at its upper end and Si the minimum outer section of the neck, can be between 1 and 12, better between 1.4 and 2.
    The ratio D / D2 between the maximum diameter D of the container body and the outside diameter D2 at the upper end of said portion of substantially frustoconical shape may be between 0.3 and 5, preferably between 1.2 and 2. For example, D = 51 mm and D2 = 35 mm, ie D / D2 = 1.46.
    The container may contain a cosmetic or other product.
    The container may contain a liquefied or compressed gas, with an overpressure of between 1 and 13 bar (105 and 13.105 Pa). The invention also relates to a container for a pressurized bottle as defined above.
    Another aspect of the invention relates to a pressurized bottle, the plastic container of which comprises two substantially frustoconical portions separated by a non-frustoconical intermediate portion, in particular of radius of curvature in longitudinal section chosen so that the intermediate portion is tangent at its ends to each of substantially frustoconical portions. Such a shape, if it is less advantageous than a frustoconical shape of a single segment in that it limits the size of a label glued to the container, nevertheless remains interesting in terms of mechanical strength conferred. The curved intermediate portion avoids the presence of ridges capable of concentrating the stresses in an area where the thickness of the wall is advantageously the smallest and the container exposed to shocks. This advantage is obtained even when the height of at least one frustoconical portion is less than one third of the total height of the container. Such a shape also avoids passing below the minimum thicknesses to be respected and ensures a better distribution of the material. Preferably, the cumulative height of the substantially frustoconical shaped portions corresponds according to this aspect of the invention to more than half of the total height of the container.
    The connection zone may be the largest diameter zone of the container body or the smallest diameter zone of the container body.
    Another aspect of the invention resides in a pressurized bottle, the plastic container of which comprises two parts of substantially frustoconical shape, better frustoconical rectilinear, diverging in opposite directions, thus giving a general shape of hourglass to the container. These two parts can be joined or not. When the two parts are not joined, their axes can be offset and parallel.
    In a variant, the two portions of substantially frustoconical shape, which are more rectilinearly frustoconical, converge in opposite directions, thus giving the container a generally biconical shape. Again, these two parts may be joined or not. The invention may be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. elevation a pressurized bottle according to the invention, - 2 shows, in top view, the pressurized bottle of Figure 1, - Figure 3 is a longitudinal section of the bottle of Figure 1, - Figure 4 represents, very schematically, in axial section, the neck, - Figures 5 to 9 are views similar to Figure 3 of alternative embodiments, and - Figure 10 illustrates the measurement of the arrow on a portion of substantially frustoconical shape (the curvature has been exaggerated for the purposes of understanding).
    The pressurized bottle 1 shown in the figures comprises a dispensing system 2 mounted on a container 3 containing the product to be dispensed, for example a cosmetic product to be sprayed.
    The dispensing system 2 can be made in various ways, being provided with an actuating member 4 on which the user can press to cause the dispensing of the product by at least one outlet, for example in the form of a spray.
    The dispensing system 2 comprises a dispensing head carrying the actuating member 4 and a cup 6, fixed on the container 3, carrying a hollow control rod valve 9, driven by depression or tilting, and shown schematically. in Figure 3.
    The product contained in the container 3 leaves the valve stem 9 when it is actuated, then gains the outlet orifice of the dispensing head by one or more channels internal thereto.
    The container 3 comprises a body 10, extended at its upper end by a neck 20, the entire container 3 being made of thermoplastic material, for example PET. The formation of the container 3 may comprise the blowing of a preform within a mold into several parts, in a manner known per se. The thermoplastic material in which the container 3 is made is preferably transparent, at least at the level of the body 10.
    The total height M of the neck 20 is for example between 15 and 20 mm
    In the absence of use, the neck 20 is at least partially concealed by a removable protective cover 8, which is fixed for example by snapping on the container.
    The body 10 here has a main part 11 which extends over a distance L along the longitudinal axis X of the container 3, this main part 11 being of straight frustoconical shape widening downwards, of revolution around the X axis, apex angle with, for example between 3 and 4.5 °, the angle is in the example considered equal to 3.7 °.
    The height L of the main part 11 is in the example considered between 100 and 140 mm, being for example of the order of 125 mm.
    The outer diameter D of the main portion 11 at its base is for example between 15 and 75 mm, better between 40 and 60 mm, being for example of the order of 50 mm in the example.
    The main part 11 can be extended downwards by a first rounded portion 13, of radius of curvature Ri in longitudinal section and by a second rounded portion 14 of radius of curvature R2 in longitudinal section, with R2 ^ Ri. The second portion 14 is connected to a bottom 15 through which the container 3 can stand vertically on a horizontal flat surface.
    The bottom 15 of the container 3 has a recess defined by a frustoconical wall 18, converging towards the inside of the container, of angle β at the top of 90 ° for example.
    The frustoconical wall 18 is connected at its top to a flat wall 19 which bears the trace of the injection point of the preform used to make the container 3 by injection / blowing or compression / blowing.
    The container 3 has an annular groove 28 around the frustoconical wall 18, in which can extend the end of a dip tube connected to the distribution system, if any, this tube not being shown in Figure 3 .
    The neck 20 of the container 3 is made with at its upper end a ring 21 which allows attachment of the dispensing system 2 and more particularly the crimping of the cup 6. The neck can be crystallized or not.
    Referring to Figure 4, the thickness N, measured along the axis X, of the ring 21 is for example between 2.5 and 3.5 mm. The outer diameter W of the ring 21 is for example between 30 and 35 mm. The inside diameter Q of the neck 20 at the level of the ring 21 is, for example, between 22 and 28 mm
    The neck 20 has under the ring 21 a cylindrical portion 24 of X-axis revolution whose outer diameter U is for example between 28 and 31 mm.
    As can be seen in FIG. 4, the portion 24 is inferiorly connected, by a rounding 25 of small radius of curvature, to a second ring 26 with an outside diameter Y greater than W, for example greater than W by at least 1 mm. For example, there is between 30 and 35 mm.
    The ring 26 has a lower face 38 which is flat and perpendicular to the axis X, as can be seen in FIG. 4. This face 38 is connected to a cylindrical portion 30 of revolution, of axis X, of external diameter Di is between 15 and 28.7 mm, Di being preferably less than U.
    The ring 26 may be thinner than the ring 21.
    The rings 21 and 26 define a groove 70 between them, whose role is to allow the crimping pliers of the cup 6 to engage under the ring 21.
    The outer diameter at the upper end of the main portion 11 is D2. For example, D2 is between 15 and 51 mm, more preferably between 34.7 and 51 mm.
    D22 / Di2 is preferably between 1 and 12, preferably between 1.4 and 2.
    The distance between the plane where D2 is measured and that where Di is measured, halfway up the portion 30, is for example between 1.5 and 11.5 mm.
    The inner section of the neck 20 may be constant from an entry chamfer in the upper part of the ring 21 to the ring 26. The thickness of material ei at the portion 11 may be lower than that e2 at the base of the neck 20 and also lower than that e3 in the area which defines the bearing surface when the container 3 is placed vertically on a horizontal flat surface.
    The thickness ei is preferably less than 1.1 mm, especially for PET.
    The container 3 can be provided, as illustrated in FIG. 1, with a label 40 which is glued on the outer surface of the main part 11. The fact that the main part 11 is frustoconical makes its outer surface developable, and allows stick the label without folds.
    FIG. 5 illustrates an embodiment variant in which the values of the outer diameter D 2 at the upper end of the main part 11 of frustoconical shape and the maximum outside diameter D of the container body 3, measured here at the lower end of the main part 11, are relatively close.
    There is for example D / D2 which is between 0.3 and 5, better still between 1.2 and 2, with for example D = 56 mm and D2 = 51 mm. The neck 20 of the example of FIG. 5 may be identical to that of the example of FIG.
    In this example, the angle at the top of the main part 11 is for example between 3 and 4 degrees.
    The total height H of the container, measured between its lower end and the upper end of the neck 20, is for example between 120 and 130 mm, and the height M of the neck is between 10 and 20 mm for example.
    The shape of the container under the main part 11 is for example similar to that of the example of Figure 3, with two successive portions 13 and 14 of different radii of curvature, and a bottom having a frustoconical portion 18 extending towards the inside the container.
    The neck 20 has at its base a frustoconical wall 90 diverging downwards, with a thickness β4 greater than the thickness ei of the portion IL. The angle at the apex of the wall 90 is for example, as illustrated, greater than 90 °. .
    In Figures 6 and 7, the lower portion of the container 3 has not been shown.
    In the example of FIG. 6, the container 3 has two successive frustoconical portions 11 and 11 ', separated by an intermediate portion 60 in the form of a portion of a torus, with a radius of curvature Rim in longitudinal section, for example greater than 150 mm, in particular equal to 200 mm. The frustoconical portions 11 and 11 'may be of substantially equal length, the angle a at the top of the frustoconical portion 11 being for example between 10 and 12 degrees, while the angle a' at the top of the frustoconical portion 11 ' is less than the angle a, being for example between 4 and 6 degrees.
    The generatrices of the portions 11 and 11 'are tangent to the intermediate portion 60 at their junction with it.
    In the example of Figure 7, the frustoconical portion 11 is located under an upper portion 80 of cylindrical shape of revolution of X axis.
    FIGS. 8 and 9 illustrate the possibility for the part 11 not to be frustoconical rectilinear, but substantially frustoconical, slightly convex towards the outside, as in the case of FIG. 8, or slightly concave, as in FIG. case of Figure 9.
    To enter into the definition of a portion of substantially frustoconical shape, the maximum deflection f, measured here at mid-length Lgen / 2 of the generatrix of the part 11, as illustrated in FIG. 10, is less than 1.7% of length Lgen.
    The maximum deflection f is the distance between the outer surface of the portion 11 in the case of a rigorously frustoconical shape of X axis and the outer surface in the case of the substantially frustoconical shape. The maximum deflection is less than or equal to 1 mm, in the examples of FIGS. 8 and 9.
    Of course, the invention is not limited to the examples which have just been described. In particular, it is possible to modify the shape of the pressurized bottle, and in particular that of the container 3 or the distribution system 2.
    The container 3 may contain any means for propelling the product, for example a liquefied gas or a compressed gas. Where appropriate, the container 3 may be provided at its bottom with a throttle filling valve, especially when using compressed air as propellant.
    The pressurized bottle can be pocket or not, with dip tube or not. When a bag is present, it contains the product while the propellant exerts pressure on the bag, inside the container.
    The dispensing system 2 can have several outlet nozzles, if necessary.
    The pressure inside the container 3, before the first use, at 20 ° C, is for example between 1 and 13 bar (105 and 13 105 Pa). During filling, the vacuum is for example greater than or equal to 0.3 bar (3104 Pa).
