Definitions
- the invention relates to plastic packaging for liquid or viscous products.
- the invention is particularly in the field of hot-fill packaging (greater than 70 ° C), and conditioning by heat treatment (pasteurization).
- PET Polyethylene terephthalate
- Thermoplating is considered to be the most efficient method for improving the heat resistance of bi-oriented PET bottles.
- the principle of this process widely used on the market, is to heat treat the walls of the bottle to increase crystallization and thus improve the molecular stability at high temperature. This principle can be declined in several processes and devices of thermo-fixation described in the prior art. An important advantage of thermofixation processes is not to modify the packaging processes, the thermofixation of the bottle being performed during the manufacture of said bottle.
- bottles having undergone a heat treatment to allow the conditioning of a liquid at high temperature have several disadvantages.
- a first drawback of these bottles lies in the fact that only specific grades of polyethylene terephthalate can be used. These specific grades are more difficult to produce and generate additional packaging costs.
- a second disadvantage is related to the decrease in the production rate of the bottles because the thermo-fixing process slows down the blowing cycle.
- a third drawback is related to the weight of these bottles.
- a bottle When a bottle is filled with a hot liquid, it results after cooling a negative pressure inside the bottle; said negative pressure having the effect of randomly deforming the walls of the bottle.
- the most common method for dealing with the negative pressure in the bottle is the addition of compensation panels that allow the bottle to be deformed in a controlled manner.
- bottles with compensation panels are stiffer and therefore heavier. This results in an excess of material which is not strictly necessary for the good conservation of the product.
- the compensation panels are detrimental to the aesthetics of the packaging, which makes it less attractive to the consumer.
- Soft bags are also commonly used for packaging liquid products. These pockets are made from pre-printed thin films. These packages offer many benefits including weight, cost and compaction before and after use. However, they have drawbacks, in particular when their contents are subject to high temperature variations.
- the packaged liquid is heated, voluntarily or involuntarily (such as staying inside a car exposed to the sun), the product expands, sometimes so that the packaging can burst.
- Laminated multilayer film resulting from the complexing of several films
- PET polyethylene terephthalate
- PE polyethylene
- LDPE low density polyethylene
- LLDPE linear low density polyethylene
- HDPE high density polyethylene
- EVOH ethylene vinyl alcohol
- the invention overcomes the aforementioned drawbacks through a package, which when subjected to a change in temperature, expands and shrinks together with the packaged product.
- the packaged product designates a liquid or viscous product that may contain solid elements. Since these products are predominantly water-based, the variation in volume of said products is approximately 3% when the temperature varies from 65 ° C, which corresponds to a coefficient of volume expansion of approximately 0.00042 m 3 / (m 3 ° K) and linear coefficient of expansion of 0.00014 m / (m ° K). These values are indicative given that the thermal expansion of water varies with temperature.
- the products can also be oil-based and their behavior depends on the thermal properties of the oil used.
- This package has many advantages when used for packaging a product at high temperature. Unlike PET bottles, this packaging does not require a thermo-fixing process to avoid shrinkage of the walls under the effect of the filling temperature. Unlike PET bottles, this packaging does not require compensation panels to cope with changes in product volume during cooling.
- This packaging is characterized by the fact that its thermal expansion is greater than or equal to the thermal expansion of the product.
- the temperature of the product heats the walls of the package that expand.
- the expanded package is then sealed. Cooling, the package retracts and returns to its original geometry; after cooling, the result is a relative pressure in the package that is positive or zero.
- a slight pressure in the package after cooling is advantageous because it improves the compressive strength of the package, and it also improves the grip of the package.
- the use of the packaging in a packaging process requiring a thermal treatment of the packaging and its contents, such as the pasteurization process for example, is also particularly advantageous. During the temperature rise of the package and the product, the package expands at least as much as the product, which avoids excessive pressure buildup in the package.
- this packaging is of great interest because it adapts to temperature variations without its aesthetic properties being modified, and with very small variations in the pressure in the package.
- Another advantage of the container according to the invention is that if the packaged product is subjected to an increase in temperature, then the package will expand together with the product and thus the walls, the bottom and the welds (in the case of packaging made using flexible films) of the packaging do not undergo or very little increase in pressure and therefore easily resist.
- the invention can be used for the packaging of liquid or viscous products.
- the packaging can be made by molding, by extrusion blow molding, it can be made from films.
- a particularly advantageous package consists of a side wall formed from a film as well as a bottom and a neck connected by welding to said film.
- the coefficient of expansion of the package is greater than or equal to the coefficient of expansion of the packaged product.
- the coefficient of linear expansion of the walls of the package is generally greater than 0.00014 m / (m ° K), and preferably greater than 0.00018 m / (m ° K).
- a package based on low density polyethylene is particularly advantageous.
- Figures 1 to 4 illustrate a first embodiment of the invention consisting of a hot filling process.
- Figure 1 illustrates the package before filling.
- Figure 2 shows the thermal expansion of the package during filling of a hot product.
- Figure 3 shows the expanded package at the time of sealing of said package.
- Figure 4 illustrates the package and its contents after cooling; the packaging contracted due to the decrease in temperature.
- Figures 5 to 8 illustrate a second embodiment of the invention in which the package and its contents are heated and then cooled together.
- Figure 5 illustrates the package filled with a product at low temperature, and sealed.
- Figure 6 illustrates the package and its contents after heating in a hot bath for several minutes; the package expands under the effect of temperature.
- Figure 7 illustrates the package and its contents after cooling; the packaging contracted due to the decrease in temperature.
- Figure 8 illustrates a preferred embodiment of the invention consisting of a package formed by assembling a neck, a bottom, and a tubular body; said tubular body being formed of a laminate whose expansion coefficient is greater than 0.00014 m / (m ° K).
- the inventors have found a package that avoids the negative relative pressure in the package after hot filling.
- the first embodiment of the invention is particularly advantageous because it avoids the deformation of the packaging during cooling.
- the first embodiment of the invention is illustrated in FIGS. 1 to 4.
- Figure 1 illustrates the provision of a package according to the invention; said package 1 having a side wall 2, a neck 3 and a bottom 4; and said package being characterized by the expansion of its sidewalls under the effect of temperature.
- the packaging is fed at low temperature, said low temperature preferably being ambient temperature (20 ° C.).
- the package 1 can be cleaned, rinsed, dried before the filling illustrated in FIG. 2. In order to simplify the disclosure of the invention, only the steps necessary for the understanding of the invention are exposed.
- Figure 2 shows the filling of a high temperature product in package 1. Often, said high filling temperature is 85 ° C.
- the walls 2 of the package expand almost instantaneously.
- the expansion of the packaging is done as filling and depends on the filling level 6 which defines the limit of contact with the product 5 and the walls of the package.
- the expansion of the package is schematically illustrated by the variation in height 7. This thermal expansion of the walls 2 is generally manifested by a variation in height and diameter.
- the result is a package whose volume is greater than the initial volume.
- FIG. 3 shows the hermetic closure of the package following the filling, the product being still at a high temperature during said closing.
- a plug 8 or other known closure means is applied to the neck 3 and ensures the hermetic closure.
- a volume of gas 9 is trapped in the package at the time of closing. This volume of gas depends on the filling rate of the package. It is best to quickly close the packaging after filling to prevent this volume of gas from being too hot at the time of closing.
- the gas 9 trapped in the headspace may be air, nitrogen or any other gas or gas mixture known to those skilled in the art.
- package 1 and product 5 are at high temperature. The volume of the product 5 is therefore dilated, as are the walls of the package.
- Figure 4 illustrates the package and its contents after cooling to storage temperature. Often the storage temperature is close to the ambient temperature. Under cooling, the packaging and its contents contracted.
- a water-based liquid product for example, varies in volume by about 3% when its temperature varies between 85 and 20 ° C.
- the packaging according to the invention contracts under the effect of cooling; and its contraction is such that the relative pressure in the package after cooling is positive or zero; the contraction of the package is therefore greater than or equal to the contraction of the product.
- the linear expansion of the package is not necessarily equal in all directions.
- the linear expansion of the package in height may be greater than the circumferential expansion, or vice versa.
- the geometry of the package after cooling and shrinking is generally identical to the geometry of the package before filling and expansion. However, it is observed in some cases a slight hysteresis, the contraction of the package being slightly less than its expansion. In this case, the final volume of the package is slightly larger than the initial volume. In other cases, the contraction of the package is slightly greater than its expansion; the final volume of the packaging is therefore lower than the initial volume. As a rule, the final geometry of the package is substantially identical to the initial geometry and the package can be expanded and retracted several times reversibly.
- the cooling of the packaging has little influence, the cooling being able to be fast, slow, stepwise or continuous. Often spraying the packaging with water allows for rapid and efficient cooling.
- the various cooling methods known to those skilled in the art can be used; only the initial and final temperatures of the package having an influence on the volume variation of said package.
- FIG. 5 illustrates the provision of a package according to the invention; said package 1 having a side wall 2, a neck 3 and a bottom 4; and said package being characterized by the expansion of its sidewalls under the effect of temperature.
- the package is filled with a liquid or viscous product 5 and hermetically closed by a cap 8.
- the package and its contents are at low temperature, said low temperature preferably being the ambient temperature (20 0 C).
- a volume of gas 9 which may be air is trapped at the headspace.
- the filling rate of the package is illustrated by the liquid level 6.
- a high filling ratio is favorable because the thermal expansion of the gases is greater than that of the liquids. It is preferable to have a filling rate of the package 1 greater than 90%.
- Figure 6 illustrates the heat treatment step of raising the temperature of the package and its contents.
- a heat treatment often used is for example, to immerse for 10 minutes, the package and its contents in a water bath at 80 ° C.
- the heat treatment generates a gradual rise in temperature of the packaging and its contents, which creates the volume expansion of the product 5, and the volume of gas 9.
- the packaging according to the invention is characterized by a high thermal expansion of the walls 2 which avoids a high relative pressure in the package.
- the difficulty encountered with packaging according to the state of the art is related to the fact that the high pressure in the package can create a reversal of the bottom 4. Often, a specific bottom design 4 is necessary to prevent the bottom sagging. . This stronger bottom is heavier and more expensive.
- the invention makes it possible to overcome this difficulty; the expansion of the walls of the package during the heat treatment to prevent the build-up of pressure in the package.
- the expansion of the walls of the package is illustrated by the variation of height 7.
- the thermal expansion of the walls of the package is generally effected according to the height and circumference.
- the expansion of the package is such that it compensates for variations in the volume of the product 5 and the gas 9.
- the relative pressure in the package remains substantially constant and close to zero.
- Figure 7 illustrates the package and its contents after cooling at low temperature, said low temperature being room temperature. In general, the final temperature after cooling is equivalent to the initial temperature before heat treatment. While cooling, the product 5 and the gas 9 contract.
- the package 1 according to the invention also contracts; this contraction being illustrated by the variation of height 10.
- the value of the contraction of the package is identical to the value of the expansion 7.
- the second embodiment of the invention is particularly advantageous because of the thin-walled packaging can be used.
- the inventors have found that a package having a coefficient of linear thermal expansion greater than 0.00016 m / (m ° K) makes it possible to limit the pressure during the heat treatment; and a coefficient greater than 0.00020 m / (m ° K) is particularly advantageous.
- the packaging according to the invention is characterized by its thermal expansion and contraction properties. It has been found that the walls of the package must have a coefficient of linear thermal expansion greater than 0.00014 m / (m ° K) and preferably greater than 0.00018 m / (m ° K). Few materials used for packaging make it possible to obtain the abovementioned properties. The inventors have found that LDPE packages are particularly advantageous because of their expansion properties. Packaging obtained with certain grades of low crystalline PP make it possible to obtain sufficient dilatations; said grades of PP being preferably copolymers. It has been observed that bi-oriented packaging does not have a high coefficient of thermal expansion. Similarly a package made of a very crystalline polymer has a low coefficient of thermal expansion.
- the invention allows the realization of packaging of a wide variety; the packaging can be made by extrusion blow molding, injection, tubular extrusion, or by assembling from films.
- the packages may be bottles or flasks made by extrusion blow molding, jars or cups made by molding, flexible bags made by welding from films.
- the manufacturing process of the packaging may have a impact on the coefficient of expansion of the packaging. It is known in fact that extrusion processes orient more or less marked polymer chains. The orientation of the chains can create an anisotropy of properties resulting in expansion coefficients that differ in the direction of measurement. In order to simplify the disclosure of the invention, an average linear expansion coefficient identical in all directions is considered.
- the coefficient of thermal expansion of the package can be measured by two methods.
- One method is to measure the coefficient of volume expansion of the package by measuring the change in volume of the package as the temperature changes.
- a second method consists in measuring the coefficient of linear expansion in two perpendicular directions by taking two long and narrow strips in said directions and measuring the variation in length of said strips as the temperature changes.
- FIG. 8 An exemplary embodiment of the package is illustrated in FIG. 8.
- This package 1 comprises a tubular body 2 connected by welding to a neck 3 and a bottom 4.
- a cap 8 fits on the neck 3 and allows the hermetic closure of the container. 'packaging.
- the tubular body 2 forming the side walls can be extruded or formed from a film whose ends are connected by welding.
- the film can be monolayer and multilayer.
- the film does not have a rigid layer with a low coefficient of expansion, such as an aluminum layer or a bi-oriented polymer layer. It is observed that a thin layer of barrier-barrier polymer could be inserted into the multilayer structure.
- a LDPE film containing a thin EVOH layer has thermal expansion properties greater than 0.00018 m / (m ° K).
- the film multilayer may contain layers with a low coefficient of thermal expansion, if said layers are thin and do not block the expansion of said film.
- Said film must contain at least 70% of a polymer having a coefficient of linear thermal expansion greater than 0.00014 m / (m ° K) and preferably greater than 0.00018 m / (m ° K).
- the thickness of the EVOH layer should be less than 10% of the total thickness. If the thickness of the film is 300 microns, the thickness of the EVOH layer is less than 30 microns, and preferably less than 20 microns.
- the neck and bottom provide rigidity and strength to the package and are composed of partially rigid elements with thicker wall. Such a package expands and contracts with the product during temperature variation through its side wall. The dimensions of the neck and bottom vary only slightly with the temperature.
- the invention is not limited to the above examples for materials having an expansion coefficient greater than 0.00014m / (m ° K); said materials obtainable by polymer blending, by polymerization, by compounding or any other technique known to those skilled in the art.
- Polyolefin blends, the addition of elastomers and the production of polyolefin-based alloys make it possible to adjust the coefficient of expansion of the package to that of the packaged product.
- the multilayer structures also make it possible to modify the expansion properties of the walls of the packaging to those of the packaged product.
