Definitions
- the present invention relates to a component for flexible packaging of essentially tubular shape comprising a narrow neck at one of its ends and a flat closure at the other of its ends, said packaging being intended to contain a consumable product, such as a toothpaste, which comes out under the pressure of the fingers.
- It relates more precisely to a packaging component which comprises an anti-diffusion layer intended in particular to protect the consumable product from its environment.
- the present invention also relates to methods of placing said anti-diffusion layer.
- any hollow longitudinal object not necessarily rectilinear, resembling approximately a cylinder but whose section can be variable over the length of the cylinder and have any shape, for circular, oval or polygonal example.
- tube will be used subsequently to mention the packaging defined above.
- a tube according to the invention can comprise a plurality of compartments.
- a tube can include one or more components. Most often, there is a skirt, a head and a cap.
- the head has substantially the shape of a hollow truncated cone on which is located a cylinder forming the narrow neck and the external face of which can be threaded in order to receive a plug which is screwed into it. Alternatively, the outer face of the narrow neck is not threaded, the plug being fixed by simple pressure.
- the skirt has a substantially tubular shape. It can be manufactured either by extrusion or by winding a laminated film.
- the head and the skirt are made integral with one another by welding.
- Another possibility is to form the head by molding and fix it simultaneously to the skirt.
- a third method consists in making the tube in a single operation from a preform.
- anti-diffusion layers also called barrier layers. Due to their presence, the migration phenomenon can be greatly reduced, or even completely.
- barrier layers are described in Patent documents DE-C-19617349, FR-A-2784657, US 5372863, EP-A-496704 or WO 97/27120.
- the anti-diffusion layers are never in direct contact with the content, there is always a non-barrier layer between the anti-diffusion layer and the content, therefore a non-negligible migration in this non-barrier layer.
- the anti-diffusion layers ⁇ have relatively large thicknesses, hence a relatively high cost of material and corresponding recycling problems.
- the present invention has the particular merit of remedying the problems described above. It relates to a component for flexible packaging of essentially tubular shape comprising a narrow neck at one of its ends and a flat closure at the other of its ends, said packaging being intended to contain a consumable product which leaves under pressure. fingers, said component comprising an anti-diffusion layer intended to protect the consumable product from its environment, said anti-diffusion layer having a thickness of less than 150 ⁇ m.
- the anti-diffusion layer has a thickness of between 20 and 80 nm. This achieves an optimum anti-diffusion properties.
- the anti-diffusion layer according to the invention may consist of a plurality of layers of various compositions, such a configuration in particular makes it possible to obtain layers more resistant to abrasion or having better adhesion, this also allows to modify the optical properties of the tube.
- PVD Physical Vapor Deposition
- An anti-diffusion layer according to the invention can be obtained in different ways.
- We can cite among other things the physical vapor deposition process (PVD Physical Vapor Deposition) which consists of thermal evaporation, resistive or using an electron gun, or a cathode or laser sputtering.
- CVD Chemical Vapor Deposition
- a process particularly suited to the present invention is PECVD (Plasma Enhanced Chemical Vapor Deposition) which consists of a chemical deposition in the vapor phase assisted by plasma.
- the plasma can be generated remotely (remote plasma) from the area to be covered.
- the PECVD remote is particularly well suited, especially when it comes to leaving weld zones without an anti-diffusion layer.
- Another advantage offered by the present invention lies in the fact that, in particular with the PECVD process, it becomes possible to produce an anti-diffusion layer based on silicon oxide obtained from a precursor such as HMDSO.
- This material has the particularity of being inert, that is to say not to encourage the migration of compounds to or from the consumable product. It also offers an effective barrier effect compared to agents external to the tube such as oxygen or humidity.
- Figure 1 Presentation of a tube according to the invention.
- Figure 2 A tube head according to the invention.
- FIG. 3 A device 1 according to the invention for coating an anti-diffusion layer on the tube heads.
- Figure 4 A 2nd coating device according to the invention of an anti-diffusion layer on the tube heads.
- Figure 5 Device according to the invention for coating an anti-diffusion layer on tubes.
- Figure 6 Device of Figure 5 in another position.
- the tube (1) illustrated in Figure 1 consists of a skirt (2), a head (3) and a plug (4); a flat closure (6) being formed towards the end of the tube (1) which is opposite to that where the plug (4) is located.
- the head (3) mainly consists of a frustoconical shape (28) on which a cylindrical shape (7) is extended, the external surface (9) of which is threaded so as to allow the plug (4) to be screwed.
- An anti-diffusion layer (8) is placed over the entire interior surface of the tube (1).
- the thickness of the layer (8) which is obtained according to the PECVD process is of the order of 50 nm. It has in fact been found that this value is particularly suitable for obtaining an effective anti-diffusion effect.
- the thickness of the layer (8) is not greater than 150 nm.
- the thickness of the anti-diffusion layer (8) should not be less than 5 nm.
- anti-diffusion materials will be developed and that the thickness of the corresponding layer (8) will be less than 5 nm while retaining an optimal barrier effect.
- the anti-diffusion layer (8) extends over the entire interior surface of the head (3) which is in contact with the consumable product (5) .
- the tube portion (1) shown in Figure 2 is characterized in particular by a seamless zone (10) where the skirt (2) covers part of the head (3).
- the seamless zone (10) has substantially the shape of a cylinder whose axis merges with that of the tube (1).
- the weld zone (11) between the skirt (2) and the head (3) is located on the frustoconical surface (28) of the head (3).
- FIG. 3 illustrates a deposition apparatus 1, an anti-diffusion layer on the tube heads (3) which are placed on a sample holder (16), the whole being contained in a vacuum chamber (14).
- This device is particularly well suited when it is sought to also cover part of the external surface of the head (3).
- a plasma (13) is formed at a distance (remote plasma) relative to the deposition zone.
- the plasma source (12) chosen in the example illustrated here is a CYRANNUS device ⁇ a description of which can be found in patent application EP-A-872164.
- the process for manufacturing anti-diffusion layers, in this example, is characterized by the following steps:
- a gas mixture (shown diagrammatically by reference 17) comprising a precursor between the plasma source (12) and the samples to be treated.
- a precursor can be an organosilicon such as hexamethyldisiloxane (HMDSO).
- HMDSO hexamethyldisiloxane
- This precursor can be mixed with a carrier gas such as helium or argon which prevents the formation of powder.
- FIG. 4 shows a second device for depositing an anti-diffusion layer on tube heads (3).
- a plasma (22) is formed directly in contact with the deposition area. This process is also carried out under partial vacuum in a vacuum enclosure (23) using a pumping system (19).
- a plasma can be ignited and maintained with electromagnetic waves in the radio frequency or high frequency range between the electrode (21) and the sample holder (20) acting as a counter electrode.
- good anti-diffusion layers of silicon oxide are obtained by directly using a mixture of gases containing oxygen and a precursor of the organo-silicon type such as HMDSO. It can also be joined to a rare gas of the helium or argon type to prevent the formation of powder.
- the injector (18) of the gas mixture is directly on the vacuum chamber (23).
- Figures 5 and 6 illustrate a device similar to that of Figure 3 but which differs in that it is designed to allow the deposition of anti-diffusion layers on tubes (1) including the head (3) and the skirt (2) have been fixed together beforehand; the flat closure (6) being formed after the deposition and filling of the tube (1) carried out.
- FIG. 5 presents the case of a remote plasma where the deposition is carried out outside the plasma source.
- the plasma flow and the precursor gas (17) penetrate through the tube (1) through the end opposite the narrow neck (7) and exit there through the narrow neck (7).
- the precursor gas is introduced (17) at the level of the guides (26) of active species.
- FIG. 6 presents the case of a direct plasma where the plasma is restricted inside the tubes.
- batches of tubes (27) are introduced into the plasma source (12) by means of an elevator (24).
- the oxygen as well as the precursor, for example HMDSO, are introduced directly into the tubes (1) by one of their ends, for example the end opposite the narrow neck (7), and exit through the opposite end.
- the plasma is generated only inside the tubes (1 ).
- the anti-diffusion layer is not limited to a specific material but to any type of material constituting a layer less than 150 nm which has anti-diffusion properties.
- the invention is not limited to the coating devices described in the embodiments described above.
