Definitions
- the present invention relates to a method of hot filling a light-walled, lightweight container, especially polyethylene and filled container thus obtained.
- PET Polyethylene terephthalate
- PET is unbreakable and with good mechanical properties of preservation, permeability, which makes it very attractive and largely explains its very strong use.
- PET bottles are used for flat liquids such as oils and mineral waters. In this case, the containers undergo only very few mechanical stresses. PET is quite suitable. Indeed, these liquids are filled cold and without pressure.
- Heat Resistant more commonly referred to by the letters HR that improve the heat resistance of the container that is derived therefrom.
- a first method known as a wheel makes it possible to reach filling temperatures of 80/88 ° C.
- a second so-called two-wheel method which makes it possible to condition the liquids at temperatures of 88/95 ° C.
- a hot-filled bottle undergoes many mechanical stresses during the different phases.
- the container must withstand the forces generated during the vacuum generated by the cooling of the liquid while the container has been clogged hot, to ensure the sterility of the liquid.
- the cooling causes a double contraction, that of the liquid and that of the air of the headspace of said bottle. It is for this reason that the profiles are much more complex with panels and beams on the body, belts marked on the body as well as a shoulder between the neck and the body, whose shape is rather bulbous .
- the advantage of the thickness necessary for the mechanical strength is also to present a greater inertia at the temperature.
- the manufacture of lightweight PET bottles uses the so-called extrusion / blowing process.
- This method consists in producing a preform by extrusion, this preform having a tube profile with one end formed to the size and final shape of the neck, the other end being closed.
- the amorphous material After reheating of this preform, especially by infrared radiation, up to 100/120 0 C, the amorphous material is softened and can be blown from the inside after it has been placed in a suitable mold.
- This mold is of such dimensions that the removal of the material on cooling is taken into account so that the final container has the desired dimensions.
- the bottles thus obtained are said to be bi-oriented because they have been stretched in one direction and an omni directional inflation.
- the macromolecular chains thus oriented in two directions lead to excellent mechanical strength parameters, at room temperature.
- extrusion blow molding is also used but with more sophisticated and complex driving parameters.
- the preform is warmed to a higher temperature than in the case of lightweight containers, close to crystallization to minimize this form of PET memory and relax the constraints due to blowing.
- the initially amorphous material of this container is subjected to heat treatment during and after its forming.
- the material when stretched after softening generates an induced but reversible crystallinity, the material remaining transparent.
- the mechanical properties are increased. Then, if the heating is maintained after having generated this induced crystallization, a spherulitic crystallization occurs, causing some crystallinity of the chains already organized by bi-orientation.
- spherolitic crystallisation posterior to a bi-orientation perfectly retains the transparency of the material.
- the method achieves higher performance but at the cost of a succession of more complex steps.
- a volume draft much larger than the volume of the final container is first produced two to three times, therefore with a proportional stretching ratio.
- This blank is then reheated beyond the glass transition to relax the stresses, which causes a decrease in volume and a return to the dimensions of the preform but has a high rate of spherulitic crystallinity, this in a way proportional to a homothetic container.
- the high degree of crystallinity gives this container improved resistance to hot filling.
- the bottles obtained by the HR process have a tendency to absorb water as soon as they were manufactured, which reduces their mechanical strength and therefore temperature resistance characteristics. It is thus possible to obtain a container which initially resists at a temperature of 88 ° C. and which, after taking up water, withstands only 82 ° C. In fact, the transition temperature TG drops.
- the storage must be reduced to the maximum, the bottles are usually produced at the filling site, for use in just-in-time, which is still a constraint.
- liquids to be packaged there are several filling methods and different behaviors of the liquids to be packaged.
- There are light-sensitive liquids such as milk or beer, sensitive to the absorption of oxygen and therefore oxidizable such as fruit or vegetable juices, beer, oil, but also sensitive to water uptake, loss of gas, development of yeast, mold or bacteria.
- Liquids can include preservatives and are therefore insensitive, however some so-called flat and delicate liquids such as milks, juices, coffee, tea, fruit drinks, certain waters, do not include any preservatives and must nevertheless be packaged in the best conditions.
- there are two main routes one called “aseptic filling” and the other called “hot filling”.
- Aseptic filling is simple in theory since it consists in filling the container with a sterilized liquid and clogging said container, the packages being sterilized as the caps, the operation being conducted in its entirety in a sterile environment.
- a very important disadvantage of this method lies in the impossibility of controlling on-line sterility of the contents in each container. At most, control can be done by sampling.
- the aim of this cold aseptic filling is to require only thin-walled, low-weight, free-form bottles since the cold filling avoids the deformations due to the temperature.
- the hot filling also guarantees a quality of asepsis since the temperature control of the content is simple and easy at any time.
- the bottling line is simple and the treatments of the container and the stopper are limited since the sterilization is obtained by the hot liquid itself, introduced into the container which is immediately closed after filling. A tilting of the bottle also sterilizes the inner face of the plug in contact with the liquid.
- bottles resistant to the filling temperature between 60 and 95 0 C, more particularly between 80 and 92 ° C depending on the products.
- the bottles have high weights with substantially identical shapes related resistance constraints, which allows a very low differentiation between the marketed products.
- FIG. 1 a view of a container before filling
- FIG. 2 a view of the same container as that of FIG. 1 when filled with a hot liquid before cooling
- FIGS. 3A and 3B two 90 ° views of the filled container, after cooling and having undergone the phenomenon of collapse,
- Figure 4 the collapse container of Figures 3 A and 3B after treatment according to the method of the present invention which returns to its original shape.
- the example given relates to PET bottles but could be applied to any container of polymer material of the same kind and having similar properties.
- the method consists in performing a hot filling of a thin-walled container, the container having to have suitable characteristics as described below.
- This container is of cylindrical shape, possibly with grooves to stiffen the body, with a light base like that of the containers for mineral waters flat, but reinforced, the total weight of the container being substantially that of containers used for containers of mineral water , with equal capacity.
- the reinforced bottom usually consists of a bulging bottom to the neck with reinforcements to prevent its reversal under slight pressure.
- This container is made from either one or two wheel “HR” treatment methods, depending on the conditioning temperatures.
- the container is thus able to withstand hot and remains of reduced weight.
- the container shown in Figure 1, has a simple geometry.
- the filling is carried out from the tank of a filler of known type, usually by gravity directly into the container, the liquid being carried and maintained at a temperature of 60 to 95 0 C depending on the intended applications.
- the crystallinity can be improved as indicated in the preamble of the present application, which greatly improves the mechanical strength. It is also known that if the container is used immediately after its manufacture, the moisture uptake is very limited and the initial resistance to temperature is kept almost completely.
- the bottom having been designed with improved mechanical strength and its treatment "HR" avoids the overturning of the crown of this bottom under the effect of the load and the increase in pressure once said container closed. Indeed, the increase in temperature causes a rapid shrinkage of the volume of the container while the contained liquid, it retains its volume which generates a pressure of the interior of the container.
- the deformation is localized in the most favorable zone for mechanical deformation such as the walls for example in the case of known containers and for which no particular modification has been made. It is also noted that in the case of a less mechanically resistant zone, the deformation is reproducible on all the identical containers filled under the same conditions.
- a container is thus obtained with a bottom and a junction belt of the bottom and said body undeformed thanks to the strength of the fold formed at this junction.
- the container is stable on its bottom but with a deformed body, collapsed according to the word of the trade, which makes it unsuitable for marketing.
- FIGS. 3A and 3B These are the representations of FIGS. 3A and 3B.
- the method according to the present invention consists in reducing the volume of the container by causing a reduction in the volume of the container after partial or total cooling of the liquid.
- the method consists of releasing the frozen constraints so that the container tends to return to its original shape, that of the preform and therefore tends to find a smaller volume. This is the particularly surprising and attractive step of the present invention.
- the container is subjected to a temperature rise of at least a portion of said container so as to relax the constraints and to irreversibly deform the container on all or part of its surface.
- the rise in temperature must be rapid so as not to cause the rise in temperature of the liquid, which would cancel the differential necessary to compensate for the depression. Nevertheless, the choice of means to achieve this rise in temperature remains very wide because the ratio of the masses involved is very important.
- the few grams of PET in a container in front of the hundreds of grams of the content necessarily lead to a faster temperature rise of the envelope than the content.
- the envelope is the first subjected to infrared radiation and absorbs primarily calories.
- the volume reduction after cooling is only 3.5% of the liquid volume, so 17 ml.
- the belt between the labeling zone and the bottom and the shoulder zone being dimensionally stable, it suffices to provide a retraction of 1 to 2 mm from the diameter. It is even possible to provide a slight overpressure to compensate for the possible additional shrinkage when placing in a refrigerator such a container.
- the bottle so as to systematically conduct this air following a generatrix of said bottle at the top.
- the method can implement hot air heating because the transmission of calories between the wall and the air is very difficult, the air being very insulating. The calories are concentrated in the wall of said bottle on the area concerned and very quickly causes the desired shrinkage.
- this heating of the envelope it is also possible to achieve this heating of the envelope as soon as the internal liquid has passed below the transition temperature of the order of 40 to 50 ° C.
- the process consists in using a container that is able to withstand mechanically without deformation hot-filling of a liquid in a temperature range of a sterilized liquid, generally from 80 to 95 ° C., for example a polyethylene container, said container being made by extrusion / souff loge and having a shape memory before blowing, to fill said container with said hot liquid, to close the filled container and to cool at least below a temperature of freezing of the container, then causing deformation by forming a vacuum inside the container, then heating the container to cause a relaxation of the stresses and a return to the shape before blowing generating a shrinkage and an internal pressurization of the containing at least to compensate for the deformations suffered by the effects of depression.
- a container that is able to withstand mechanically without deformation hot-filling of a liquid in a temperature range of a sterilized liquid, generally from 80 to 95 ° C., for example a polyethylene container, said container being made by extrusion / souff loge and having
- a container filled with a pasteurized content which can be guaranteed pasteurization by a simple measurement of filling temperature.
- the cost of the container for the implementation of the process is no longer detrimental since it is completely comparable to that of containers capable of undergoing aseptic filling.
- the advantage is to be able to meet the needs of industrial filling rates, need for aseptic guarantee without requiring expensive bottling lines investment, also expensive and complex in operation.
- the process according to the present invention not only is the cost of raw material for producing a hot-filled container reduced, but this smaller quantity of raw material leads to subsequent recycling costs reduced for the same volume bottled. According to the present invention, it should be noted that provision can be made for a device suitable for implementing the method.
- One solution is to make shells comprising at least two parts so as to come wrapping the container, said shells being heated by any suitable means to emit the necessary calories.
- the shells have a substantially conjugated profile of that of the container to emit the calories closer to the walls, or even in a localized area of this wall, these shells being oriented horizontally if the heating is performed on a generator with the air in the upper part. . In this case, it is then possible to cause more intense heating in a particular area.
