The vessel with the coating material with a barrier effect, the method and the device for its manufacture

 

(57) Abstract:

The invention relates to the formation of a coating of amorphous carbon with a polymer tendency on the substrate of polymer material having the shape of the vessel that is to be obtained, such as a bottle or vial, using plasma excited by electromagnetic waves. In the reaction chamber, which was created significant depression, enter the harvesting vessel of the polymeric material forming the substrate is injected into the reaction chamber at least one carbon source gaseous substance with a very low pressure. The original gaseous substance is chosen among the alkanes, alkenes, alkynes, aromatic compounds or combinations of some of them. At the same time create in the reaction chamber of the microwave electromagnetic excitation in the microwave range (8-12) relatively low power, capable of forming a plasma at temperature conditions, which, on the one hand, keep the polymer at a temperature below the temperature of transition to the glassy state, and which, on the other hand, cause the deposition peregrinovna carbon with a polymer tendency. The technical result - the creation of the vessel is to the vessels, such as bottles or vials heterogeneous composition of a material with a barrier effect and a polymeric material.

Vessels made of polymeric material such as polyethylene terephthalate (PET), have the inconvenience of being permeable to certain gases, namely oxygen and carbon dioxide.

Consequently, carbonation drinks continuously lose their carbon dioxide that goes into the atmosphere through the polymeric material: lifetime saturated with carbon dioxide liquid contained in the bottle of PET, does not exceed almost a few weeks or, at most, a small number of months (e.g., 4-6 months).

As a consequence, also the atmospheric oxygen enters through the polymeric material in contact with the liquid contained in the vessel, with its ability to oxidize, reducing its characteristics: the lifespan of PET bottles filled with beer, may not exceed, practically, several weeks to months (e.g., 2-5 weeks).

There are ways to improve the barrier effect of the polymer materials from which to fabricate the vessels by increasing the thickness of the polymer wall with a layer of material with a higher burgerville, for example obtained on the basis of aliphatic polyamides and/or mixtures of different materials. Vessels made in this case of pre-formed multi-layer materials, in which the layer of material with a barrier effect is enclosed at least between two layers of polymeric material (e.g., PET). Beer bottles, designed to have a lifespan significantly higher (e.g. up to 12 weeks).

Anyway, a great disadvantage of these multi-layered vessels is peeling off layers from one another. In addition, as a preliminary forming material, and the manufacture of the vessel from him by blowing or drawing with blowing, are complex and expensive processes that require precautions.

It was also proposed to handle vessels of polymeric materials by coating the outside layer of a suitable material, such as grades (PVDC) or thermocatenulatus resin. In any case, increase the barrier effect remains weak and presence of the deposited material leads to difficulties with secondary processing of primary polymer material.

Crickett and these solutions do not offer protection from the inconvenience the resulting contact: the possibility of migration of certain components of the polymer in the liquid, the possibility of a chemical reaction of the polymer with the liquid, the transition of acetaldehyde in the liquid and so on, as well as phenomena that can cause organoleptic problems.

It was also proposed to put a layer of material with a barrier effect, for example, solid carbon, on the wall of the polymer, for example of PET, using plasma (document US 5041303).

In the patent EP 0773166, also mentions the possibility of forming such a layer of carbon on the inner side of the vessel.

Put thus, the layer of carbon permits, of course, to get rid of some of the inconveniences which have been described above.

But we are talking about a relatively thick layer of solid carbon or carbon diamond type ("diamond-like carbon or DLC). The vessel wall, thus obtained, is, therefore, of the inner layer of solid carbon DLC, which is of considerable hardness, and an outer layer of polymer, such as PET, which has significant deformation capacity. Because of their different and incompatible mechanical characteristics of both layer - polymer and solid plepler vladusic barrier effect, using one of the above technical solutions, not common, due to the complexity of the application of different methods, low productivity and high value manufacturing.

The technical result of the invention is to immediately eliminate some of the problems listed above, which are found in vessels with improved barrier effect, known at the present time. The objective of the invention is to create a vessel that provides effective protection for its contents, with the ability to manufacture industrially with the help of not very sophisticated tools in an acceptable economic conditions.

To solve this problem, according to the first embodiment, the vessel, in particular a bottle or vial, non-uniform structure made of a material with a barrier effect and from a polymeric material, and a material with a barrier effect consists of amorphous carbon with a polymer tendency, which cover the substrate from a polymeric material. The substrate is made in the procurement of the vessel, which has the final form of the vessel.

Under amorphous carbon with a polymer tendency to understand the carbon containing not only the communication of CH and CH2already present is rcii relations CH3CH2and SN, respectively, 0, 40, and 60 in solid carbon and 25, 60, 15 in amorphous carbon with a polymer tendency, while the proportion of electronic States sp3, sp2and sp set 68 respectively, 30 and 2 for solid carbon and 53, 45 and 2 for carbon polymer type).

The choice of amorphous carbon with a polymer tendency allows us to solve problems caused by the rigidity of solid carbon or DLC: indeed, amorphous carbon with a polymer tendency is much lower mechanical stiffness than solid carbon, and deformation capacity of a layer of such material is comparable to the deformation ability of a polymeric material such as PET: a vessel wall in accordance with the invention made of amorphous carbon with a polymer tendency, bonded to a substrate of a polymeric material such as PET (polyethylene terephthalate), can withstand normal deformation without the posting of these two layers.

Of course, amorphous carbon with a polymer tendency, due to the inherent physico-chemical structure, has a lower coefficient of molecular permeability than solid carbon used up to the present time. Thought h was used up to the present time, and layers with the barrier effect of the carbon formed from solid carbon or DLC. However, surprisingly trials conducted with amorphous carbon with a polymer tendency, showed that the barrier effect is obtained in some operational conditions, largely sufficient in practice for bottling beverages, saturated with carbonic acid, or oxidizing liquids.

You can also use the nanocomposites type carbon (DLN), i.e., composed of dual closely related lattices, stable and random, one of which is a lattice of amorphous carbon with a polymer tendency (a-C:H, up to 50% relations sp3and another could be the lattice of silicon stabilized by oxygen (a-Si:O), and nanocomposites with inclusions of metal atoms.

The coating of amorphous carbon material with a polymer tendency has a thickness of predominantly less than 3000 E. (too large thickness gives the carbon layer significant mechanical stiffness, which can cause it to tear and/or detachment), preferably signed between 800 and 1500 E.

It should be noted that amorphous carbon with a polymer tendency, despite the fact that he is still transparent when the above thickness is echino, in some operating conditions, the efficiency of ultraviolet barrier protection is a function of the thickness of the coating and, in a very interesting way, strongly increases with the intensity of the ambient light (a factor of about 8 in the dark, but a factor of about 30 in daylight).

Polymeric material, which is, in practice, a polyolefin or a polyester, such as PET or PEN (polyethylenterephthalat), perhaps due to its own rigidity of the carbon layer to be thinner. On this occasion, it should also be noted that the carbon coating reduces the deformation of the vessel wall under the action of pressure saturated gas (carbonated liquid, such as liquid, saturated with carbon dioxide. The vessel, therefore, maintains a stable shape and its internal volume remains constant, because of this there is no change of the composition of the liquid, which it is.

The coating material with a barrier effect can be applied to the outer surface of the workpiece vessel, however, preferred if the coating forms the inner layer of the vessel, since it is necessary to separate the polymer material and the liquid contained in the vessel. In this slucero the chemical reaction between the substances of the polymer and the liquid, probable migration of acetaldehyde in the liquid, etc.

In the proposed application draws attention to the fact that the structure of the vessel according to the invention is based on the establishment of chemical bonds between the surface carbon atoms of the polymer substrate, which are free (have) a chemical bond, and the carbon atoms of the material are brought into contact with the polymer with one free chemical bond is ready to bind with the free (available) coupling surface of the carbon polymer substrate. In these conditions, it is through chemical bonding, therefore, extremely strong, the coating of carbon material associated with the polymer substrate; a carbon material having an addition polymer trends explained above, a strong chemical bond, accompanied by at least a relative capacity of the carbon coating to deform, these two combined features result in a structure that no longer has the disadvantages (in particular, delamination of the layers) previously used vessels made of hard carbon or DLC.

For applying a carbon coating with carbon atoms having free chemical Manny application method.

For solving the problem according to the second variant of the invention proposes a method in which use plasma with electromagnetic excitation for the formation of the vessel, such as a bottle or vial, the heterogeneous composition of a material with a barrier effect and a polymeric material forming the substrate having the form of above mentioned vessel that is to be obtained, and the above-mentioned polymeric material forming the substrate, causing the material with a barrier effect, consisting of amorphous carbon with a polymer tendency, while in the chamber, which was created significant depression, enter the harvesting vessel of the polymeric material forming the above-mentioned substrate, pump to the reaction chamber at least one carbon source substance in a gaseous state at a very low pressure below 10 mbar, and as the initial substance use alkanes, alkenes, alkynes, aromatic compounds, or a combination of some of them, create in the reaction chamber of the microwave electromagnetic excitation in microwave frequency range is relatively small capacity, capable of forming a plasma at temperature conditions, which, on the one hand, keep the polymer in Anie amorphous carbon with a polymer tendency.

According to one variant of the harvesting vessel of polymer material is closed, while the carbon source gas substance injected into the chamber from the outside of the workpiece, and the volume enclosed between the walls of the chamber and the outer surface of the workpiece forms a reaction chamber, allowing the coating of amorphous carbon with a polymer tendency to be deposited on the outer surface of the billet container.

According to another variant of the carbon source gas substance injected into the material of the vessel from a polymeric material, which forms a reaction chamber, and at the same time create the harvesting vessel pronounced negative pressure, whereby plasma is generated within the workpiece and the coating of amorphous carbon material with a polymer tendency will be applied to the inner surface of the workpiece vessel; in addition, in order to avoid deformation of the vessel due to the vacuum that it creates, at the same time reduce the pressure in the chamber to reduce the pressure differential inside and outside of the workpiece. In addition, mainly in this case, the camera has a transverse dimension that is close to the transverse size of the workpiece receptacle so tightly pril to create a vacuum means less power.

Thanks devices, characterizing the method according to the invention, it becomes possible to perform the coating of amorphous carbon material with a polymer tendency that is low to the desired thickness, less than 3000 , and it is enclosed between 800 and 1500 , in a short time, of the order of several seconds, not exceeding twenty seconds, with reasonable power microwaves on the order of several hundred watts (for example, about 200-600 watts), resulting in a power density of about 0.5 to 2 watts per cubic centimeter. In the result, the corresponding temperature rise in the polymer material constituting the workpiece receptacle and serves as a substrate for deposition (inside or outside depending on the case) carbon coating, remains low and below the transition temperature of the polymer in the glassy state (approximately 80oFor PET).

These are the conditions of forming the carbon coating by microwave plasma at low pressure (not exceeding a few millibars and in practice, from 0.01 to 0.5 mbar) or "cold plasma", which lead to amorphous carbon structure with a polymer tendency, i.e., formed by or containing a grid of amorphous peregrinovna operatring coating of amorphous carbon with a polymer tendency in the harvesting vessel to create an oxygen plasma, able to form pure oxygen for cleaning the workpiece receptacle.

In addition to receiving vessel with a layer with a barrier effect with good mechanical adhesion to the polymer substrate, the method corresponding to the invention provides, moreover, a distinct advantage of facilitating the manufacture of sterile receptacles on the conveyor with aseptic conditionality.

To obtain a high degree of asepsis before the formation of the internal coating of amorphous carbon with a polymer tendency in the harvesting vessel is sprayed with a bactericidal substance, then create an oxygen plasma, thereby the plasma contributes to the formation of a strong suppressive environment, are able to reduce bacterial contamination.

In this case, applying antibacterial additive pre-sprayed in the form of droplets or introduced in the form of steam, for example, by kapleobrazovatelya, on the inner surface of the workpiece receptacle (for example, hydrogen peroxide, phosphoric acid, water vapor, and so on), which can reduce the initial bacterial contamination in order to meet the requirements of sterilization.

The objective of the invention is also solved by using the device the LM or the bottle, the heterogeneous composition of a material with a barrier effect and the polymer material forming the substrate (workpiece vessel) having the form of above mentioned vessel that is to be obtained, and the device includes a plasma generator having a chamber provided with means to discharge the original gaseous substances and electromagnetic excitation means for coating the above-mentioned polymer material forming the substrate, a material with a barrier effect, containing amorphous carbon material with a polymer tendency, means to discharge the original substance is connected with a generator of the original substance in the gaseous state, which is used as alkanes, alkenes, alkynes, aromatic compounds, or a combination of some of them, and coating the above-mentioned polymer material forming the substrate, a material with a barrier effect, containing amorphous carbon material with a polymer tendency, means to discharge out in an enclosed space and adjusted to deliver the original gaseous substance under very low pressure below 10 mbar, electromagnetic excitation means is configured to generate micro exceeding the size of the workpiece receptacle, to be processed, and means for forcing open the camera outside the harvesting vessel, so that the harvesting vessel when it is closed, the apparatus generates plasma from the outside of the workpiece receptacle and it is on the outer surface of the workpiece vessel will be a coating of amorphous carbon material with a polymer tendency.

According to the second method of application of the discharge of the original substance in the gaseous state are facing the inside of the workpiece receptacle located in the chamber, and means are provided suction opening in the workpiece receptacle and is able to create a full-blown depression, whereby plasma is generated within the workpiece receptacle and the inner surface of the workpiece vessel will be a coating of amorphous carbon with a polymer tendency. In order to avoid deformation of the vessel due to the vacuum that it creates, pumping means is configured to simultaneously lower the pressure in the chamber to reduce the pressure differential inside and outside of the workpiece. Mostly the camera is fitted with a movable insulated cover the object, equipped for mounting the injector means discharge source of gaseous substances is Uchenye for fixing the workpiece receptacle for her neck, clutching the edge of the above-mentioned workpiece receptacle sealed to the inner side of the aforementioned cover, surrounding the above-mentioned suction holes and the injector. In addition, it is desirable that the means of attachment could be moved in the axial direction to bring the workpiece receptacle to the inside of the lid, closing the above-mentioned outlet and the injector before coating and removing the finished vessel after coating.

Means of electromagnetic excitation contain the waveguide radially connected to the cavity surrounding the camera, and in the above-mentioned cavity is provided by means of longitudinal short circuit surrounding the chamber and the waveguide, and means transverse short circuit.

Mainly to facilitate the use of suction and to avoid use of funds with very large size, the camera has a transverse dimension that is close to the transverse size of the workpiece receptacle.

Means of microwave electromagnetic excitation contain the antenna connected to the waveguide and located radially in the cavity surrounding the camera, and the above-mentioned cavity is equipped with ectromagnetic excitation contain the antenna, connected to the waveguide, and is located coaxially in the cavity surrounding the camera, and the above-mentioned cavity is provided by means of longitudinal short circuit.

Thanks to the device according to the invention, in particular due to the limited duration of the treatment, it became possible industrial application of the process of manufacture of the vessel with a layer with a barrier effect, which allows these vessels performance, compatible with the current requirements of the bottling of liquids.

The invention will be better understood upon reading the detailed description which follows, some methods of execution, data only as a non-limiting example. In this description refers to the accompanying drawings, on which:

- Fig.1-3 illustrate schematically in sectional view, respectively, three examples of execution of the device, allowing to obtain a vessel containing a layer of material with a barrier effect according to the invention, and

- Fig. 4 is a view in section of a preferred example of the manufacturing apparatus in Fig.1, adapted for the formation of the layer of material with a barrier effect, which is located inside the vessel.

According Fig.1 the device has propoglexeme processing, and how the desired connection, and which cover the camera 2, bounded by a wall 3 of a material which is transparent to electromagnetic microwaves, for example, quartz.

The chamber 2 is closed, for example, from the top of the movable cap 4, allowing its installation on the place of the object to be processed in the camera and the notch after processing.

To create the vacuum chamber 2 is connected to an external pumping means (not shown) through at least one outlet. In Fig. 1 is provided with two discharge 5 in the bottom and in the lid 4 (pumping symbolically shown by arrows 6).

For discharge, mainly under pressure below 1 mbar, the original gaseous material in the chamber 2 is provided, at least one injector 7, connected at least with one generator source of gaseous or liquid substances (not shown), such as a reservoir, a mixer or kapleobrazovatelya. The injector 7 passes through the cover, in which it is fixed, for example, being located coaxially within the outlet 5 of the means of pumping.

The cavity 1 is connected with a micro electromagnetic generator (not shown) through the waveguide 8, which is located radially with respect to the, smolewski to carry out the adjustment of the cavity. On the opposite side (diametrically opposite, if the cavity is a circular cylinder, as is the case in practice) is the outlet of the waveguide 9, provided with adjusting piston 10, with the possibility of axial movement, which forms the cross-device short circuit.

Finally, in the cavity 1 are respectively the top and bottom two annular plate 11 surrounding an enclosed space 2 and forming a longitudinal short circuit for microwaves.

If you want to put carbon on a substrate of polymer material, i.e., on the wall of the billet container of polymeric material, a source of gaseous substance may be selected from among alkanes (e.g. methane), alkenes, alkynes (e.g., acetylene) and aromatic compounds.

The pressure inside the reaction chamber (formed either by the camera or the harvesting vessel, as will be explained later) must be low, mostly below about 10 mbar, in practice of the order of from 0.01 to 0.5 mbar.

In addition, it is necessary that the heating experienced by the polymer substrate material, would remain quite small and did not reach for PET). Therefore, for the reaction of the application you want to use is not very high power microwaves, for example a maximum of a few hundred watts microwaves in the microwave range (e.g., about 2.45 GHz).

Given the conditions of application, namely, low temperature deposition of carbon, get highly hydrogenated amorphous carbon containing not only the radicals CH and CH2, but also a significant fraction of the radicals CH3. We are talking, therefore, about the carbon with a polymer tendency or soft carbon, which has a much lower stiffness than solid carbon or DLC. This layer of carbon with a polymer tendency has this ability to deform, making it suitable to match small deformations of the polymer forming the substrate. As a result of this get the best mechanical connection of polymer and carbon and the risk of posting becomes significantly less virtually eliminated.

In any case, you need to understand that despite the fact that carbon with a polymer tendency or "soft" carbon has a lower stiffness than solid carbon or DLC, it still retains a significant rigidity, which, in any case, significantly higher than the stiffness of the polymer and, inherent in the finished vessel; a polymeric substrate can therefore be partially exempted from performing the functions of the mechanical resistance of the finished vessel. You can also reduce the thickness of the polymer substrate and, therefore, the amount of polymer, reaching for the manufacture of each vessel.

In addition, the presence of a layer of carbon increases the mechanical resistance of the vessel and therefore reduces, nullifies the deformation ability of the vessel, filled with highly carbonated liquid: form and, therefore, the volume of the vessel remain constant and thus eliminate the possibility of partial degassing of the liquid.

Of course, the above-mentioned advantages additional to those fundamental advantages that were mentioned previously and which are the main. These benefits are in receipt of barrier effect prevents, in particular, the gas exchange between the liquid contained in the vessel, and the atmosphere.

Finally, thanks to the use of funds according to the invention it is possible to obtain the rate of deposition of several hundred angstroms per second and the processing time of the order of several seconds, which is fully compatible with the processes of ppm generating plasma, suitable for applying a layer of amorphous carbon with a polymer tendency envisaged in the framework of the present invention.

So, in Fig.2, keeping the same layout of the cavity 1 and camera 2 (saved by the same numerical designations to denote identical nodes, as in Fig. 1), the microwave excitation is obtained here by using the antenna 13, which penetrates radially into the cavity 1 through its side wall and which is connected coaxial conductor 14 with the waveguide 15 cross-type.

Fig. 3 illustrates another method of execution axial microwave cavity 1, proceeding from the antenna 13, which is installed in the cavity 1, almost perpendicularly above the bottom and approximately coaxially c camera 2. Longitudinal short circuit is formed here only the upper annular plate 11, at the same time, there is only one outlet 5 in the chamber 2.

Different ways of making devices that have just been described, provide a drawing of the carbon material on the outer surface of the billet container of polymeric material: chamber 2 is thus considerably larger than the total harvest of the vessel, so that the plasma could razvitiya.

Anyway, as earlier mentioned, the outer layer of the carbon material provides only a partial barrier effect, which does not allow to prevent interaction between the polymer substrate and content, usually liquid.

Obtaining a complete barrier effect can only be achieved by using a layer with a barrier effect, which is located on the substrate within the vessel. The application of this inner layer requires the appropriate equipment handling device.

In Fig. 4 shows a variant of the device according to Fig.1, adapted to overlap the inner carbon layer. Camera 2 mainly has such a structure that its transverse dimension or diameter is slightly larger than the transverse size of the harvesting vessel to be processed, in order to facilitate the creation of vacuum in the chamber, described below. In order to avoid deformation of the workpiece due to the vacuum that it created, at the same time reduce the pressure in the chamber to reduce, rather revocation, the pressure difference between the inside and outside of the workpiece.

Through the cover 4, which has the ability to move in the vertical direction (double arrow 16) in order d capture of the vessel 18. This rod has the possibility of vertical movement (double arrow 19) and if necessary turn.

The cover 4 has an internal liner 20 with an axial channel 21, in which or in relation to which opens the injector 7 gaseous source materials. At its lower end an axial channel 21 provided with a seat 22 that is designed to accept virtually sealed the top edge 23 of the neck of the workpiece receptacle 18 for the precise axial positioning of the workpiece receptacle. The liner 20 has, in addition, a circular hole, through which passes the rod 17 of the grip, which is reported to the Central channel 22; this opening forms an outlet 5 in the direction of means of pumping to create a vacuum. To ensure the conditions necessary to create a plasma only in the harvesting vessel, it creates a pronounced depression at the same time in the chamber to create the aforementioned compensatory depression.

Thanks to this device, you can create a plasma in the harvesting vessel, which itself thus becomes the reaction chamber, which provides the domestic imposition of a carbon material.

As an example, in the device according to Fig.4 was used acetyl the flow of 80 sccm5under pressure of 0.25 mbar. The residual pressure inside the preform is approximately 0.2 mbar and it was found that the residual pressure of 50 mbar inside the confined space is sufficient to prevent deformation of the workpiece under these conditions. Excitation was provided by the microwaves in the microwave range with a frequency of 2.45 GHz (i.e., wavelength =12 cm in vacuum); the power of the microwaves is about 180 watts. Under these conditions could overlay carbon with a slew rate of about 250 E/s, i.e., to obtain a layer thickness of about 1500 about 6 seconds.

According to the second example of the device of Fig.4 was used acetylene with a flow rate of about 160 sccm5under pressure of about 0.1 mbar. In this case, when the power of the microwaves is about 350 watts for a bottle of 0.5 liter or when the power of the microwaves of about 500 watts for a bottle 1 liter, got barrier layer is about 2-3 seconds.

The plasma generated during application of the layer of carbon may be sufficient for cleaning the first degree inner surface of the workpiece.

For processing with a higher level of treatment you can apply a simple oxygen plasma, creating a reactive substance, apenergy reduce the initial bacterial infection in proportions sufficient to meet the sanitary criteria.

This processing is carried out for a time not exceeding ten seconds, which is compatible with industrial installations.

To obtain a high degree of sterilization it is necessary to resort to the help of bactericidal agent, such as hydrogen peroxide H2ABOUT2to which, after a predetermined time of contact with the workpiece affected by oxygen plasma: physico-chemical phenomena, generated by the plasma in a mixture of peroxide of hydrogen, oxygen, lead to the emergence of these and other reactive substances, which are strong suppressors and can have a strong bactericidal effect.

Processing using plasma may also be provided in the reception removal bactericidal agents such as phosphoric acid, which is a suppressor.

Here it is possible to emphasize that, regardless of its bactericidal properties, hydrogen peroxide acts as a Creator of free radicals among the carbon atoms of the polymer present on the surface of the substrate: the surface of the polymer increases the number of free radicals, ready for the plasma deposition of the carbon layer spray hydrogen peroxide on the surface of the substrate, being then exposed to oxygen plasma in order to obtain better bonding layer of carbon with a polymer.
