Definitions
- the present invention relates to improvements made in the field of manufacturing bottles or the like in thermoplastic material, and it relates more specifically to improvements made to polypropylene preforms for making bottles or the like by blow molding or stretch blow molding and to a process. blow molding or stretch blow molding for such a preform.
- the most commonly used material currently is polyethylene terephthalate (PET) due to certain very interesting properties of bottles made of this material (in particular their good mechanical strength allowing them to contain carbonated drinks, the possibility of filling with a hot liquid, the good transparency of PET does not alter the appearance of the liquid they contain, a relatively good oxygen barrier effect, etc.).
- PET also has certain drawbacks (such as its relatively low softening temperature preventing filling with an excessively hot liquid, its high permeability to water vapor, preventing its use for packaging lyophilized products, etc., and also its high and fluctuating cost). So there are currently attempts to replace, at least for some applications, the PET by other materials which are more efficient at least in certain respects and / or less costly. Thus, attempts have been made to use polypropylene in place of PET, at least for certain applications.
- polypropylene has a softening temperature higher than that of PET (beyond 120 ° C instead of 75 ° C) which allows filling with a hotter liquid than in the case of PET, a sterilization treatment or the possibility of reheating the content using microwaves; polypropylene has a characteristic of impermeability to the passage of water vapor which is much higher (of the order of 5 to 10 times) than that of PET and it may be suitable for the packaging of lyophilized products.
- its cost is lower than that of PET, even taking into account the clarifying agent that it is desirable to add to it to cancel its natural opalescence.
- container with narrow opening and elongated body in the remainder of this description, is meant any container whose opening has a cross section smaller than that of its body: it may be a bottle or a container analogous such as a can, bottle, or the like, which has a narrow neck or neck.
- the Applicant has been able to establish that, for obtaining containers with a narrow opening and satisfactory elongated body, and this in mass production and with manufacturing machines operating at a high rate (typically the same rate as for the manufacture of the same types of PET containers), it was necessary to have perfect control of the conformation of the polypropylene preform as well as certain parameters of the blowing or stretch blow molding, while the tolerances on this are much wider with PET.
- the invention therefore aims to provide means (polypropylene preform and blowing or stretch-blowing method of this preform) having specific characteristics which ensure the perfectly controlled production of containers with narrow opening and elongated body of perfect quality, and this for mass production at high rates similar to those used for the manufacture of similar PET containers.
- a polypropylene preform for the manufacture of containers with narrow opening and elongated body by blow molding or stretch blow molding is characterized, being arranged in accordance with the invention, in that it is able to withstand, during the blowing or stretch-blowing step, a longitudinal elongation in a ratio of between about 2 and 3.5, preferably between about 2.5 and 3, and a radial elongation in a ratio between approximately 2 and 3, preferably between approximately 2 and 2.5.
- the longitudinal elongation ratio is greater than or equal to the radial elongation ratio.
- the longitudinal aspect ratio is approximately 2.7 and / or that the radial aspect ratio is approximately 2.3.
- the provisions which have just been set out ensure that the polypropylene preform is capable of undergoing both longitudinal and radial elongation making it possible to end up with a container with a narrow opening and elongated body, such as a bottle or the like, having strictly the desired shape; in other words, it is possible, with preforms thus arranged, to manufacture containers with narrow opening and elongated body of strictly repetitive shapes in large series and at a rate comparable to that practiced with PET preforms.
- the invention provides a method for manufacturing containers with a narrow opening and an elongated body by blowing or stretch-blowing a polypropylene preform as set out above, which method is characterized in that '' the preform is subjected to a longitudinal elongation in a ratio between about 2 and 3.5 and a radial elongation in a ratio between about 2 and 3.
- the preform preform to be heated so that the temperature difference between the core of the wall and the external face of the wall is between approximately 0 and 15 ° C., preferably approximately 10 ° C., the core temperature preferably being higher than the temperature of the external face of the wall (or skin temperature).
- the preform blowing can be carried out under a substantially lower blowing pressure than that, high (typically of the order of 40 ⁇ 10 5 Pa), recommended for PET preforms; thus, the blowing fluid can have a pressure not exceeding approximately 20 ⁇ 10 5 Pa.
- polypropylene has a significantly lower thermal conductivity (approximately twice less) than that of PET: the natural cooling of the containers in PET at the end of the blow-molding or stretch-blow-molding process proves to be insufficient for polypropylene containers which remain hot, and therefore fragile, longer, which can have drawbacks: for example in the case of filling immediately after leaving the mold and especially when the mold is cooled so that the wall of its molding cavity is at a temperature for example between 10 and 20 ° C, typically 15 ° C, the container risks d '' be damaged and / or deformed; this is why, in order to avoid this drawback with certainty, it is advantageous for the container, immediately after being blow molded or stretch blow molded, to be subjected to a cooling step.
- the single figure is a schematic representation, in diametral section, of an example of a preform intended by the invention associated with a schematic representation of an example of a container with a narrow opening and elongated body, such as bottle, flask , can or the like, capable of being obtained by blowing or stretch-blowing the preform.
- a polypropylene preform 1 intended for the manufacture of a container 2 with narrow opening and elongated body, here a bottle, by a blowing or stretch-blowing process.
- a preform of this type comprises a neck 6 which is constituted by a part present on the preform, which part is not modified during the stages of transformation of the preform into a container.
- the preform 1 has a zone 5 whose constituent material will form the shoulder 8 of the container 2; in the example illustrated, this zone 5 comprises a first substantially cylindrical part 5a extended by a second substantially frustoconical part 5b (illustrated in gray in the drawing).
- This second frustoconical part is extended by two successive parts 3, 4 respectively constituting the body and the bottom of the preform, the constituent material of which will be found respectively on the body 9 and on the bottom 10 of the container 2.
- the preform 1 is arranged so as to be able to withstand, during the blowing or stretch-blowing process, a longitudinal elongation in a ratio (i.e. ratio of the developed half-length L of the body of the container 2 to the developed half-length 1 of the body 3 of the preform 1) which is between approximately 2 and 3.5 and a radial elongation in a ratio (that is to say ratio of the mean diameter D of the body of the container 2 to the mean diameter d of the body of the preform 1) which is between approximately 2 and 3.
- a ratio i.e. ratio of the developed half-length L of the body of the container 2 to the developed half-length 1 of the body 3 of the preform 1
- a radial elongation in a ratio that is to say ratio of the mean diameter D of the body of the container 2 to the mean diameter d of the body of the preform 1 which is between approximately 2 and 3.
- the developed half-length is the dimension of the neutral fiber of the wall taken from below 7 (here the underside of the collar) of the neck 6 and the center of the bottom 4 for the preform 1 (illustrated by a dashed line in the left half of the preform in the accompanying drawing) or the center of the bottom 10 for the container 2 (illustrated by a dashed line in the right half of the container in the attached drawing).
- the mean diameter is the diameter d of the part of the body 3 of the preform 1 or the diameter D of the part of the body 9 of the container 2 taken from the respective neutral fiber.
- the best results are obtained for a longitudinal aspect ratio of between approximately 2.5 and 3 and a radial aspect ratio of between approximately 2 and 2.5.
- the longitudinal aspect ratio is greater than or at least equal to the radial aspect ratio.
- the longitudinal elongation ratio is approximately 2.7, and then the radial elongation ratio is approximately 2.3.
- the polypropylene preform 1 has a body 3 whose wall has a maximum thickness e p which is less than about 3.5 mm, typically about 2.8 mm; it is also desirable that it has a bottom 4 whose thickness e f is not greater than about 2.2 mm, typically about 2 mm.
- the thickness e ep is defined as being the thickness taken at mid-height of the said second part 5b and the thickness e p is the maximum thickness of the wall of the body 3 of the preform.
- the preform be made of a polypropylene having a softened creep index (called “melt flow index” or MFI by specialists in the field) which is between about 8 and 40, preferably between about 12 and 30, and typically about 20.
- a clarifying agent can be added to the polypropylene, in a manner known per se, so that the final container with narrow opening and elongated polypropylene body no longer has the characteristic opalescence of natural polypropylene and has an acceptable transparency, close to that of a PET container.
- the invention also provides a method for manufacturing containers with a narrow opening and an elongated body by blowing or stretch-blowing preforms having the above characteristics according to the invention, which method consists in subjecting the preform a longitudinal elongation in a ratio of between about 2 and 3.5 and a radial elongation in a ratio of between about 2 and 3.
- the longitudinal elongation ratio is between about 2.5 and 3.
- the radial elongation ratio is between approximately 2 and 2.5.
- the longitudinal aspect ratio (L / l) is greater than or equal to the radial aspect ratio (D / d).
- the longitudinal aspect ratio is about 2.7 and / or that the radial aspect ratio is about 2.3. It is desirable, to optimize the conditions of controlled deformation of the preform, that the preform is heated so that the temperature difference between the core of the wall and the external face of the wall is between approximately 0 and 15 ° C. , preferably around 10 ° C, the core temperature preferably being higher than the temperature of the external face of the wall (or skin temperature).
- Polypropylene has a lower mechanical resistance than that of PET, and this characteristic turns out to be very interesting in the context of the blowing or stretch-blowing process because these operations can be carried out using a fluid (typically air ) under a pressure significantly less than that, high (typically of the order of 40 x 10 5 Pa), required by blowing or stretch-blowing a PET preform.
- a fluid typically air
- high typically of the order of 40 x 10 5 Pa
- the pressure of the blowing fluid can be between approximately 10 and 20 x 10 s Pa, typically being approximately 15 x 10 5 Pa.
- polypropylene has a significantly lower thermal conductivity than that of PET: cooling natural that PET containers undergo at the end of the blowing or stretch-blowing process proves to be insufficient for polypropylene containers which remain hot, and therefore fragile, longer, which can have drawbacks (for example in the case of filling immediately after leaving the mold, and especially when the mold is cooled so that the wall of its molding cavity is at a temperature of, for example, between 10 and 20 ° C, typically 15 ° C, the container may be damaged and / or deformed); to avoid this drawback with certainty, it is advantageous for the container with a narrow opening and elongated body, immediately after being blow molded or stretch blow molded, to be subjected to a cooling step.
