Definitions
- the present invention relates to a device for distribution of a product, packaged in the form of a liquid, particularly intended for applications cosmetic, dermatological, pharmaceutical or ophthalmic and all perfume products.
- She aims more particularly a bottle or container of dispensing for liquid product provided with a end valve and / or pump closure with tip, whose surfaces in contact with the principle assets have been designed to allow the passage of air by diffusion through the walls of the bottle.
- the dispensing bottles are constituted by a rigid or flexible container, containing the product to be distributed and a distribution head forming a valve or pump.
- the walls of these bottles are made from a material that is impervious to the surrounding environment, generally air and water, in order to avoid apart from an alteration of the product contained by the air and on the other hand to avoid a diffusion of the product through walls. It is therefore necessary to provide on these flasks a vent, usually placed on the pump body or on the valve head, to compensate for the volume of liquid that was expelled at outside.
- the present invention therefore aims to overcome these disadvantages of offering a dispensing bottle fitted with a head fitted with a valve or pump "airless" (without air intake) whose mechanisms are without a venting device, this last carried out by diffusion through a wall of the bottle.
- the dispensing bottle of a product packaged as a liquid, particularly intended for cosmetic applications, dermatological, pharmaceutical, ophthalmic or any perfume product, comprising a container containing the product to be distributed, connected by one from its ends to a head fitted with a pump "airless” or a valve, characterized in that the bottom of the container is made of a plastic material, containing an antioxidant contact agent and / or non-migrating antiseptic, allowing air intake while avoiding the passage of contaminating agents and / or oxidant.
- object of the invention comprises a container 1 containing the solution in the form of a liquid to be dispensed.
- This preferably rigid or flexible enclosure includes one of its ends a distribution system 3 can be an end valve or an "airless” pump 4 with a cover 5, the pump body "airless” immersed in the liquid.
- all or part of the walls of the enclosure is made of a material plastic, especially thermoplastic polymers injectables such as polyolefins, PVC, technical polymers, and whose properties air permeability are high, to allow the passage of air through the walls of the enclosure.
- the three-dimensional network of selected macromolecules allows air diffusion, but prevents passage contaminating agents for the product contained in the container, including bacteria.
- the substance and the bodies are assembled by known means (snap-fastening, ultrasonic, vibration welding) so that conform a container which authorizes a diffusion of air through one of the walls, especially the one forming the bottom.
- the container, object of the invention is surmounted by a dispensing head fitted with a valve or pump, which distributes the liquid contained in the bottle.
- a dispensing head fitted with a valve or pump, which distributes the liquid contained in the bottle.
- the bottle acquires rigidity and therefore retains its shape and its volume after distribution of the product.
- expulsion of the product generates a depression in the volume of the container, which promotes the diffusion of a volume of air corresponding to the volume of liquid missing through the permeable wall.
- the capture of oxygen molecules through the network three-dimensional macromolecules is improved by the addition of oxygen absorbers to the latter.
- the air intake sterile without risk of pollution bacterial, without oxygen recovery in progress use.
- the areas in contact with all or part of the different parts of the dispensing head 3 provided an "airless" pump 4 or a valve, with the product to distribute are processed so as to fix on these last an antioxidant contact agent and / or antiseptic, non-migrant, i.e. remaining fixed on the polymer.
- the deposition is carried out of a metal, in particular chosen from silver, copper, zinc, mercury, by electrodeposition on different metal or plastic parts.
- antibacterial treatment is carried out using a grafting process between a organo-metallic compound (especially chosen from salt silver, copper, zinc, mercury, lead) or organic, and preferably a hydrocarbon support macromolecular, in particular a polymer.
- organo-metallic compound especially chosen from salt silver, copper, zinc, mercury, lead
- organic especially organic, and preferably a hydrocarbon support macromolecular, in particular a polymer.
- grafting process a chemical reaction is carried out between the product to be grafted and the support, so that they are chemically linked to each other.
- the product in our case the antibacterial agent, is hooked so stable on the support and cannot migrate or unhook the support in the solution which is distributed through said device, object of the invention.
- the grafting is carried out in particular using ionizing radiation, of the alpha, beta or gamma type.
- ionizing radiation of the alpha, beta or gamma type.
- the antibacterial agent to be grafted and the surfaces of the support are in contact with each other and under the action of the energy of ionizing radiation, they perform stable chemical bonds.
- both the surfaces of the different pieces to be grafted and the molecules of the product of the antibacterial agent each have structures chemicals including tertiary carbons, unsaturated carbons or any chemical group which may be ionized by ionizing radiation, thus forming free radicals that interact with each other.
- the different pieces in plastic are molded in the presence of an agent non-soluble antibacterial, especially silver incorporated into the plastic at the time of molding.
- a polyethylene molding in the presence of 1% by weight of a silver-based antibacterial agent provides effective protection from the environment contaminant (a population of 50,000 individuals Echerichia Coli is reduced in 6 hours, to less than 10 individuals).
- bottles, object of the invention according to the materials plastics chosen for their development, have either flexible permeable walls, or permeable walls rigid, for flap configurations respectively or pump.
- the present invention offers multiple advantages because it reduces the toxicity of the product contained in the container due to the absence of preservatives antibacterials and / or antioxidants, the use of a bottle according to the invention is therefore carried out so sterile.
