Description

contacting module of a first product in a container with a second product, apparatus and associated method

The present invention relates to a contacting module of a first product in a container with a second product, the module being of the type comprising:

- a hollow body defining a primary circulation channel of the first product, the main channel having an upstream opening for insertion in a volume of first product, and a downstream opening for connection to a dispensing mechanism of the first product, body comprising a mixer arranged in the main channel,

- the body defining at least one reservoir containing the second product, and at least one auxiliary channel opening into the main channel at a tapping point.

Such a module is intended to be inserted into a conventional dispensing device comprising a container and a dispensing mechanism, such as a bottle with a pump, aerosol or other device.

The first product is for example formed of submillimeter sized capsules dispersed in a continuous phase. Such capsules generally comprise a liquid encapsulated in a gelled body envelope. These capsules are used in many technical fields.

Thus, in the food industry, such capsules are used to contain various additives that improve the properties of a food product, such as taste or shelf life.

In the pharmaceutical industry or in the cosmetics industry, the abovementioned capsules include filled with biologically or cosmetically active products. They are used in particular to protect their content and control the release of the product they contain.

Such capsules are also used in biochemical applications to immobilize cells in bioreactors or as artificial cells in implants.

In all these applications, the capsule shells are usually made of a biocompatible material with the human body. For this purpose, it is known to form the envelope with polymers such as polysaccharides, which are biocompatible, biodegradable and in most cases non-toxic. These polymers can advantageously pass from a liquid state in solution at a substantially more viscous state to form a gel providing mechanical retention of the liquid contained in the capsule.

Such capsules may be dispensed from a bottle by opening the bottle and using a sampling tool.

However, in some cases, especially in the cosmetics field, it is advantageous to dispense a product in a container with a dispensing mechanism comprising a pump or an aerosol.

Thus, the distributed product is projected onto a keratin surface. However, the dispensing devices equipped with a pump generally commercially available are not suitable for dispensing capsules. In particular, it is necessary to rupture the capsules to release the product they contain at the time of distribution, otherwise the device becomes unusable.

However, no suitable device exists to perform such an operation. for example known from WO-97/27947 a dispenser device comprising a module of the aforementioned type. This device allows mixing and dispensing two separate products initially contained in the device.

However, the presence of check valves limits the type of products that can be distributed using the distribution mechanism. In particular, the capsules can not be easily supplied from this device.

An object of the invention is therefore to obtain a contacting module which is simple to manufacture and inexpensive, and which is particularly adapted to permit dispensing of any type of product, especially in the form of capsules.

To this end, the invention relates to a module of the above type, characterized in that the main channel is released over its entire length between the first product introduction upstream opening and the tapping point.

The module according to the invention may comprise one or more of the following characteristics, taken in isolation or in any technically possible combinations:

- the auxiliary channel is released over its entire length between the reservoir and the main channel;

- the main channel extends along a longitudinal axis at least adjacent to the tapping point, the auxiliary channel opening transversely into the main channel;

- the body defines an injection nozzle of the second product in the main channel protruding into the main channel to the tapping point;

- at the tapping point, the main channel includes a first fluid, the auxiliary channel containing a second fluid, the viscosity ratio between the first fluid in the main channel and the second fluid in the auxiliary channel being between 1 100;

- the difference in viscosity between the second fluid in the auxiliary channel and the first fluid in the primary channel is between 1 Pa.s and 100 Pa.s;

- the first product in the primary channel comprises a continuous phase and a plurality of capsules containing a fluid heart;

- the capsules have a diameter greater than 500 microns, preferably greater than 1 mm;

- each capsule has an outer casing holding the heart, the second product being adapted to weaken and / or break the casing to release the heart.

- the main channel has a cross section greater than or equal to the cross section of each capsule at least between the upstream opening and the tapping point.

- the second product contains a biologically active and / or a cosmetic product;

- the wall of the body defining the auxiliary channel is opaque.

The invention also relates to a device for dispensing a mixture formed from a first product contacted with a second product, the device comprising:

- a container defining an internal space for receiving a first product;

- a dispensing mechanism mounted on the container; and

- a module according to any one of the preceding claims, disposed in the internal space in contact with the first product, the downstream opening of the main channel being connected to the dispensing mechanism, the upstream opening of the main channel opening into the space internal.

The dispensing device according to the invention may comprise one or more of the following features, (s) alone or according to all technically possible combinations:

- the dispensing mechanism comprises an own conveying means to cause the first product in the inner space through the main channel for contacting with the second product.

The invention also relates to a method of dispensing a mixture formed from a first product contacted with a second product, of the type comprising the steps of:

- providing a device as defined above;

- actuation of the dispensing mechanism; - flow of the first product in the main channel from the upstream opening to the downstream opening;

- second injection product in the main channel from the tapping point of the auxiliary channel;

- contacting the first product with the second product downstream tapping point of the auxiliary channel;

- mixing the first product and the second product to the mixer;

- dispensing the mixture out of the device through the dispensing mechanism.

The method according to the invention may comprise one or more of the following features, (s) alone or according to all technically possible combinations:

- the first product comprises a continuous phase and a plurality of capsules having an outer shell and a fluid heart, the mixture between the first product and the second product resulting in the weakening and / or rupture of the casing to release the fluid heart in the continuous phase.

- downstream of the tapping point, the capsules are broken after contact with the second product, the fluid emerging from the mixer being devoid of capsules to allow without blocking the fluid distribution through the dispensing mechanism.

The invention will be better understood from reading the following description given purely by way of example and with reference to the accompanying drawings, wherein:

- Figure 1 is a schematic cross-sectional view along a median plane of a first dispensing device comprising a module according to the invention;

- Figure 2 is a view similar to Figure 1 of the module according to the invention;

- figure 3 is a view similar to Figure 1, during the first use of the device of Figure 1;

- Figure 4 is a view similar to Figure 1, after several uses of the device of Figure 4.

In what follows, the terms "upstream >> and" downstream >> are used relative to the normal direction of flow of a fluid. The terms "top >>" >> less, agree on the guidelines shown in FIGS.

A first distribution device 10 according to the invention is illustrated by Figures 1 to 4. This device 10 comprises a container 12 receiving a first product 14, a mixture 16 of module 14 first product with a second product 18, the module 16 being disposed in the container 12.

The device 10 further comprises a dispensing mechanism 20 of the mixture formed by the first product 14 and second product 18. The module 16 is secured to the mechanism 20.

In this example, the first product 14 is advantageously formed by a plurality of capsules 22 dispersed in a continuous phase 24. Each capsule 22 comprises a fluid heart 26 and an outer shell 28 surrounding the gelled entire outer surface of the heart 26. The capsules 22 are, for example capsules as described in the patent application WO 2010/063937 of the Applicant.

In this example, each capsule 22 is spherical in shape and preferably has an outer diameter greater than 500 micron and preferably submillimeter. The capsule diameter is generally less than 5 mm and is in particular between 1 mm and 3 mm.

The heart 26 contains at least one fluid preferably selected from a biologically active product, a cosmetic product, or a clean edible product to be consumed.

When the first product is a biologically active product, it is advantageously selected among anticoagulants, anti-thrombogenic, anti-mitotic agents, anti-proliferative agents, anti-adhesion, anti-migration, cell adhesion promoters, factors growth, antiparasitic molecules, anti-inflammatory, angiogenic, the angiogenesis inhibitors, vitamins, hormones, proteins, antifungals, antimicrobial molecules, antiseptics or antibiotics.

Alternatively, the heart 26 contains reactive agents such as proteins or reagents for forming a bioreactor, or form artificial cells for implants.

A cosmetic product that may be contained in the heart, for example, cited in the COUNCIL DIRECTIVE of 27 July 1976 on the approximation of the laws of Member States relating to cosmetic products (76/768 / EEC / OJ L 262, 27.9.1976, p . 169). This product is for example a cream, emulsion, lotion, gel and oil for the skin (hands, face, feet, etc.), a foundation (liquid, paste, powder), beauty masks ( excluding superficial abrasion skin products chemically), foundations (liquids, pastes, powders), a makeup powder, powder, after-bath powders for personal hygiene, etc. toilet soaps, deodorant soaps, etc. perfumes, colognes and eau de cologne, a preparation for baths and showers (salts, foams, oils, gels, etc.), hair care products: hair dyes, bleaches, waving, straightening, fixing cleaning styling (lotions, powders, shampoos), for maintenance (lotions, creams, oils), styling (lotions, lacquers, brilliantine), a cleaning product (lotions, powders, shampoos) a shaving product (soaps, foams, lotions, etc.), make-up and cleansing the face and eyes, a product designed to be applied on the lips, a product for the care and make-up nails, products for external intimate hygiene, a sunscreen product, tanning product without sun, a product for skin whitening, anti-wrinkle product.

Shareholders edible products to be consumed by a human or an animal are preferably vegetable purees or fruit such as mango puree, pear puree, coconut puree, onion cream, leeks, carrots, or other preparations which mix several fruits or vegetables. Alternatively, it is oils such as cooking oil, on the type of olive oil, soybean oil, grape seed oil, sunflower oil, or any oil extracted from plants.

The heart 26 is advantageously in the form of a pure liquid first fluid, a solution of the or each first fluid in a liquid solvent, a dispersion such as an emulsion or suspension of the or each first fluid in a liquid.

The viscosity of the heart 26 is notably less than 2000 cps

The heart 26 is based on a predominantly aqueous phase or conversely of a predominantly oil phase.

The gelled shell 28 of the capsules 22 preferably comprises a water-containing gel and at least one polyelectrolyte reactive with multivalent ions. In an advantageous variant, the casing 28 further contains a surfactant resulting from the manufacturing process. By "reagent polyelectrolyte to polyvalent ions >> is meant within the meaning of the present invention a polyelectrolyte capable of passing from a liquid state in an aqueous solution to a gel state in response to contact with a gelling solution containing multivalent ions such as ions of an alkaline earth metal chosen, for example calcium ions, barium ions, magnesium ions.

In the liquid state, the individual polyelectrolyte chains are substantially free of the flow relative to each other. An aqueous solution of 2% by weight of polyelectrolyte then has a purely viscous behavior with shear rates characteristic of the shaping process. The viscosity of this zero shear solution is between 50 mPa.s and 10000 mPa.s preferably between 3,000 mPa.s and 7000 mPa.s.

Individual polyelectrolyte chains in the liquid state advantageously have a molecular weight greater than 65,000 g / mol.

In the gelled state, the individual polyelectrolyte chains form with multivalent ions, a coherent three-dimensional network that holds the heart 26 and prevents its flow. The individual channels are selected from each other and can not flow freely from each other. In this state, the viscosity of the gel formed is infinite. In addition the gel has a flow stress threshold. This stress threshold is greater than 0.05 Pa. The gel also has a modulus of elasticity non-zero and greater than 35 kPa.

The three-dimensional gel polyelectrolyte contained in the envelope 28 traps water and the surfactant when present. The mass content of the polyelectrolyte in the casing 28 is for example between 0.5% and 5%.

The polyelectrolyte is preferably a biocompatible polymer harmless to the human body. It is for instance biologically produced.

Advantageously, it is chosen from polysaccharides, synthetic polyelectrolytes based on acrylates (polyacrylate sodium, lithium, potassium or ammonium, or polyacrylamide), sulfonates based synthetic polyelectrolytes (poly (styrenesulfonate) sodium, for example). More particularly, the polyelectrolyte is selected from alkaline earth alginate such as sodium alginate or potassium alginate, gellan or pectin.

Alginates are produced from brown algae called "laminar >> designated by the term" sea weed >>.

Such alginates preferably have a content of alpha-L-guluronate greater than about 50%, preferably greater than 55% or even above 60%.

The surfactant is preferably an anionic surfactant, a nonionic surfactant, a cationic surfactant or a mixture thereof. The molecular weight of the surfactant is between 150 g / mol and 10,000 g / mol, preferably between 250 g / mol and 1500 g / mol.

In the case where the surfactant is an anionic surfactant, it is for example selected from an alkyl sulfate, a sulfonate alkyl, alkyl aryl sulfonate, alkali alkyl phosphate, a dialkyl sulfosuccinate, a salt of alkaline earth saturated fatty acid or not. Such surfactants advantageously comprise at least one hydrophobic hydrocarbon chain having a carbon number greater than 5, or 10 and at least one hydrophilic anionic group, such as a sulfate, a sulfonate or a carboxylate connected to one end of the hydrophobic chain.

In the case where the surfactant is a cationic surfactant, it is for example selected from a salt of alkylpyridium halide or alkylammonium such as chloride or bromide, n-éthyldodecylammonium, chloride or bromide cetylammonium (CTAB) . Such surfactants advantageously comprise at least one hydrophobic hydrocarbon chain having a carbon number greater than 5, or 10 and at least one hydrophilic cationic group, such as a quaternary ammonium cation.

In the case where the surfactant is a nonionic surfactant, it is for example selected from polyoxyethylene derivatives and / or polyoxypropylenated fatty alcohols, fatty acids, or alkylphenols, arylphenols, or from alkyls glucosides, polysorbates, cocamides .

The mass content of surfactant in the casing 28 is greater than 0.001% and is advantageously greater than 0.1%.

In this example, the envelope 28 is constituted exclusively of polyelectrolyte, surfactant, and water. The sum of the contents by weight of polyelectrolyte, surfactant, and water is then equal to 100%.

Alternatively, each capsule 22 is of the type described in patent application FR 10 61404 of the applicant. Each capsule 22 then comprises a heart 26 which contains an intermediate drop of an intermediate phase placed in contact with the gelled shell 28. The heart 26 includes at least one internal drop of an internal phase disposed in the intermediate drop.

The mass content of capsules 22 in the first product 14 is for example greater than 20% especially greater than 40%.

The continuous phase 24 is for example formed by a gel viscosity between 12 Pa.s and 100 Pa.s.

These viscosities are measured by the following method.

Using a Brookfield type viscometer with a mobile (Spindle) size (No.) is placed about 05. 150 g of solution in a beaker of 250 ml volume, with a diameter of about 7 cm so that the height of the volume occupied by 150 g of solution is sufficient to reach the marked on the movable gauge. Then we start the viscometer at a speed of 10 RPM and wait for the value on the screen is stable. Once stable, there decreases the rotational speed and viscosity of once the measurement is resumed stable display. This procedure is repeated until it reaches the lowest speed. The viscosity at the lowest speed is greater than 1 Pa.s, preferably greater than 100 Pa.s. The second product 18 is for example a clean product to weakening and / or breaking the casing 28 to allow release of the heart 26 in the continuous phase 24.

In the case where the envelope 28 is a gelled shell, in the form of ionic gel particles, the second product 18 present in the module 16 contains for example a compound capable of chelating the ions capable of forming the gel of the envelope 28 .

These compounds are able to form highly stable metal complexes. They are adapted to be bonded to metal cations in the form of one of its conjugate bases.

Among these chelating compounds may include EDTA or ethylene diamine tetraacetic acid, or EGTA, ethylene glycol tetraacetic acid or an alkali salt of an acid, such as a sodium or potassium salt of a acid, such as citric acid or acrylic acid, polyacrylic acid, phytic acid, phosphoric acid, tartaric acid.

The mass concentration of chelate-forming compound is in particular greater than 10% and is for example between 15% and 30%.

In another variant, the second product 18 is a polymer based on polyacrylate, or a phosphorus based acid such as thytique acid.

Alternatively, the second product 18 further contains a biologically active product or a cosmetic product as defined above.

The second product 18 advantageously further contains a viscosity modifier such as a thickener, as a gum, including xanthan gum. Alternatively, the viscosity of 18 second product is greater than the viscosity of the first product 14, including greater than the viscosity of continuous phase 24 of the first product 14.

In another variant, the viscosity of the second product 18 is less than the viscosity of the first product 14, in particular lower than the viscosity of the continuous phase 24 of the first product 14.

In one example, the viscosity of the second product 18 in the tank is between 1, 2 and 10 Pa.s. The viscosity of the continuous phase 26 is between 12 Pa.s and 100 Pa.s

The difference in viscosity between the two phases, expressed in terms of their relationship, can vary from about 1 to about 100.

In particular, the viscosity of the second product 18 is selected to prevent diffusion of the species contained in the second product 18 to the first product 14, although these products 14, 18 are in contact part, on a duration greater than 10,000 hours, including more than 365 days. The viscosity of each product 14, 18 is also greater than 1 Pa.s, preferably greater than 100 Pa.s.

As shown in Figure 1, the container 12 includes a bottom wall 40, a sidewall 42 and an upper wall 44 defining an insertion opening 46 of the dispensing mechanism 20.

The container 12 delimits an internal space 48 which opens outwardly through the insertion opening 46. The inner space 48 contains the first product 14 and the mixture 16 of module.

The distribution mechanism 20 is of known type and not described in detail. It comprises an actuator 50 and a clean conveying means 52 for circulating a fluid from an upstream opening 54 situated in the inner space 48 of the container 12 to a downstream dispensing opening 56 for dispensing the fluid outside of the device 10.

The conveying means 52 is for example a pump operable manually, or electrically or hydraulically. Alternatively, the fluid medium 52 is an own propulsion means to push the fluid contained in the internal space 48 through the actuating member 50 to the dispensing opening 56. This means of propulsion is by example an aerosol.

Referring to Figure 2, the module 16 of contacting comprises a hollow body 60. The body 60 delimits a reservoir 62 of second medium, a main channel 64 for circulating the first product 14 and contacted with the second product 18 and an auxiliary channel 66 connecting the reservoir 62 of second medium to the main channel 64.

The body 60 further comprises a mixer 68, preferably a static mixer, disposed in the main duct 64 downstream of the tapping point 69 of the auxiliary channel 66 into the main channel 64.

In this example, the body 60 is tubular in shape. It has a hollow peripheral wall 70 of axis AA 'vertical in Figure 1. The hollow wall 70 delimits successively, moving away from the axis A-A ', the main channel 64, the auxiliary channel 66 and the tank 62.

In this example, the circumferential wall 70 comprises an outer cylindrical partition 72 or prismatic section and an inner wall 74, spaced from the outer wall 72. The internal wall 74 preferably has a cross-section homothetic with the inner partition 72.

The wall 70 further comprises an annular partition 76 lower shutter and an upper wall 78. The walls 72-78 define inside the tank 62. They close off the reservoir 62 substantially completely, with the exception of the partition 78 having at least one opening 80 for filling the reservoir 62 with the exception of the auxiliary channel 66 which opens into the reservoir 62.

The inner wall 74 delimits externally the main channel 64.

The main channel 64 thus extends axially along axis AA 'inside the inner partition 74 between an upstream opening 82 product insertion to be placed in the interior space 48 in contact with the first cosmetic product 14 and a downstream opening 84 through which the upstream opening 54 of the mechanism 20 is inserted sealingly.

According to the invention, the main channel 64 is completely clear between the upstream opening 82 and the tapping point 69 of the auxiliary channel 66.

The cross section of the main channel 64 is thus greater than the maximum cross section of each capsule 22. The capsules 22 are able to enter without distortion and without obstruction, in the main channel 64 through the upstream opening 82 and to be conveyed without impediment to tapping point 69.

In particular, no valve, in particular no non-return valve is interposed in the path of the first product 14 between the inner space 48 and the tapping point 69, thus ensuring a flow without obstacle of this product, in particular when it comprises 22 capsules.

The auxiliary channel 66 is formed in the peripheral wall of the body 60, preferably in the inner wall 74. It has a cross section smaller than the cross section of the main channel 64. This cross-section is particularly less than the maximum diameter of the capsules 22.

The auxiliary channel 66 extends continuously between an upstream inlet 88 opening into the reservoir 62 of second product and a downstream outlet at the tapping point 69.

In the example shown, the auxiliary channel 66 is completely clear throughout its length between the inlet 88 and the tapping point 69. A valve, in particular no non-return valve is interposed on the auxiliary channel 66. the fluid in the auxiliary channel 66 is in constant contact with the fluid circulating through the main channel 64 at the tapping point 69.

In the example shown in the figures, the point of stitching 69 is disposed radially towards the axis AA 'in the main channel 64 relative to the inner wall 74. It defines an injection nozzle 90 of second product in the main channel 64. the nozzle 90 has an inclined surface 92 converging toward the axis AA 'by moving from the upstream opening 82 to the downstream opening 84.

Furthermore, in this example, the auxiliary channel 66 has a first longitudinal portion 94 extending over substantially the entire length of the body 60, taken along the axis AA 'and at least one second longitudinal portion 96, connected to the first longitudinal section through an elbow 98.

As described above, the mixer 68 is a static mixer. It comprises a plurality of static mixing elements 98 interposed projecting into the main channel 64 to define a tortuous path of the fluid flowing in channel 64.

The mixer 68 is disposed downstream, and spaced axially from the tapping point

69 to define an intermediate region 100 of contact between the first product conveyed from the upstream opening 82 and the second product 18 injected through the auxiliary channel 66. In this example, the mixing elements 98 are formed by baffles arranged head to tail, which have an L-shaped section

The mixing module 16 is attached integrally in the container 12 to be fixed to the dispensing mechanism 20. It thus has a total volume less than the volume of the inner space 48.

It is advantageously mounted in the container 12 from a disassembled configuration located away from the inner space 48 and the mechanism 20 and an assembled configuration in the internal space 48 of the dispensing mechanism 20, wherein the main channel 64 is connected downstream to the upstream opening 54 of the dispensing mechanism 20.

The module 16 can thus be inserted in a simple manner in containers 12 of standard configuration by adapting to various distribution mechanisms 20.

The operation of the dispensing device 10 according to the invention will now be described.

Initially, as shown in Figure 1, the module 16, the reservoir 62 is filled with the second product 18 is mounted on the dispensing mechanism 20 then is inserted into the inner space 48.

The interior space 48 is also filled with first product 14. The first product 14 advantageously comprises capsules 22 disposed in the continuous phase 24.

The continuous phase 24 is then removed from the main channel 64.

The difference in viscosity between the first fluid in the main channel 64 and the second fluid in the auxiliary channel 66 is selected to substantially prevent diffusion of species of the first fluid into the second fluid, on an upper time scale to several hours, especially greater than 365 days.

Thus, the difference in viscosity, expressed in terms of viscosity ratio between the first fluid in the main channel 64 and the fluid in the auxiliary channel 66 can vary from 1 to 100, using viscosity values ​​as measured by the method described above.

In one example, the viscosity of the second product 18 in the tank is between 1, 2 and 10 Pa.s. The viscosity of the continuous phase 26 is between 12 Pa.s and 100 Pa.s

It is therefore possible to use a module 16 wherein the auxiliary channel 66 as the main channel 64 are completely disengaged, thereby simplifying the design of the module 16 and improves its operation.

When the user of device 10 wishes to dispense the product 14, it actuates the actuating member 50.

The conveying means 52 are then activated to cause an input of first product 14 in the main channel 64 by suction. As shown in Figure 3, the first product 14 back into the main channel 64, which leads to suction the second product 18 present in the auxiliary channel 66 from the tapping point 69 (see Figure 3).

The first product 14 and second product 18 then mix in the intermediate region 100 and then into the static mixer 68 before being conveyed to the upstream opening 54 of the dispensing mechanism 20.

Then, the mixture thus formed of first product 14 and second product 18 is dispensed through the downstream opening 56, for example for application to a keratinous surface of a user.

When the first product 14 contains capsules 22, and the second product

18 contains at least one compound own to weaken and / or break the casing 28 of the capsule 22, the contacting between the capsules 22 and the second 18 product, downstream of the stitching item 16 causes the rupture of the shell 28 .

The heart 26 is then released in the continuous phase 24 and mixes with the continuous phase 24 to form a continuous fluid containing the heart 26, the envelope residue

28, the second product 18 and the continuous phase 24.

This continuous fluid then passes easily through the dispensing mechanism 20, in particular when this mechanism 20 comprises a pump.

With the module 16 which has just been described, and there is no obstacle in the main channel 64 to the tapping point 69, the capsules 22 back into the main duct 64. Once contacted with the second product 18, the capsules 22 become brittle and break down, to release their heart 26. This causes an effective distribution of the fluid in the heart 26. the dispensing device 10 is particularly adapted for dispensing a first product 14 comprising the capsules 22 of submillimeter size containing a heart 26.

Furthermore, although the module 16 is of particularly simple design, the amount of fluid dispensed at each actuation of the dispensing mechanism 20 is substantially constant and controlled, in particular by suitable choice of the viscosity of the second product 18, and by dimensioning adequate auxiliary channel 66.

Alternatively, the first product 14 is in homogeneous form and does not include capsules 22. It comprises for example the compounds to be mixed in the second product 18 only during dispensing of the first product 14.

In a variant (not shown), the module body 16 defines a plurality of reservoirs 62 containing each of the second separate products. Each reservoir 62 is then connected to the main channel 54 via its own auxiliary channel 86 or by a separate single auxiliary channel 86 into a plurality of separate compartments.

In another alternative, the body 60 of the wall 70 located around the side channel 86 is opaque to visible light, especially for wavelengths between 400 nm and 800 nm, so as not to expose the product contained in the channel auxiliary 86 to light.
