Definitions

  • the present invention relates to a can for chemical-pharmaceutical-food use, particularly for containing pressurized aerosol solutions.
  • a cap which has the purpose of protecting the valve and the actuator during the period of transport and any storage.
  • the aerosol container termed more commonly can, is a pressurized vessel which contains:
  • the product may flow out in the form of droplets, foam, paste or powder, as a function of the type of valve used.
  • plastic materials are divided (as occurs for glass) into two very distinct categories.
  • Cans that belong to the "unprotected" category are the ones that offer a lower degree of safety which, in particular contexts, can cause damage to the user and therefore are limited in their use.
  • hot water bath test One of the tests that are present in both categories is one known as "hot water bath test”.
  • This test consists in completely immersing the cans, once they have been filled and sealed, in a bath of hot water, so as to simulate the behavior of the content at a pressure that corresponds to the pressure that would be obtained in an environment at a constant temperature of 50°C.
  • aerosol generators i.e., the assembly of the can, the valve and the actuator, still have defects, some more severe and potentially dangerous while others are simply related to purely aesthetic, packaging and marketing factors.
  • solutions of propellant gases and particles (be they solid or liquid) in suspension are contained in aerosol cans and these solutions are introduced in the vessels under pressure so that the generator can operate correctly.
  • Pressurization is the first risk factor for these products: it can in fact constitute a double-edged sword. While on the one hand the internal pressure causes the product to exit with the optimum and desired intensity and consistency, on the other hand it can constitute a potential danger.
  • pressurization of the generator is maintained by virtue of the can and the valve and, if one of these two components has problems, such as for example holes, signs of corrosion, defects in the valve, or even if the generator is just subjected to high temperatures (well above the normal ideal preservation or use temperature), depressurizations of the content may occur and, in the most severe cases, during which the force developed by sudden depressurization of the content is too intense, the vessel can burst, leading to burns or injuring anyone who might be in the vicinity of the explosion with splinters of the material of which the can is made.
  • the second drawback is linked to the products dispensed by the generator.
  • the market sectors of aerosol are many, and some of them relate to the use of products that are per se dangerous for the health or for the environment, such as insecticides; other products are diluted by using concentrated solvents, which also are pollutant or dangerous, as in cleaning products or paints. It is also for these reasons that some types of aerosol product that are not completely empty should be handled as pollutant/dangerous waste. The presence, if any, of flammable volatile substances within the aerosol is another danger.
  • the flammability of these substances can lead to burns in various cases; for example, the dispersion of the product within a closed and not properly ventilated environment might lead (besides to possible intoxication caused by inhalation of the product unless appropriate precautions are taken) to the creation of a potentially explosive environment, in which highly flammable volatile particles of the propellant (or of the product) accumulate, creating a potentially dangerous cloud.
  • Flammability is one of the risk factors that can be subjected to verification by means of a series of tests; in particular, flammability is attested during the dispensing of the product within a closed space with an open flame and flammability at a distance, as explained in the preceding paragraph.
  • the third drawback that is observed in almost all current aerosol generators is the shape.
  • the aim of the present invention is to provide a can for chemical-pharmaceutical-food use, particularly for containing pressurized aerosol solutions, that complies with the currently applicable statutory provisions on the subject, overcoming the drawbacks noted above.
  • an object of the present invention is to provide a can that offers the greatest assurances of safety and reliability and at the same time does not alter the product contained therein.
  • Another object of the present invention is to provide an aerosol generator that is as much as possible recyclable, minimizing its environmental impact.
  • Another object of the present invention is to provide an aerosol generator that is highly reliable, relatively simple to provide, and economically competitive if compared with the background art.
  • a can for chemical-pharmaceutical-food use particularly for containing pressurized aerosol solutions, having a substantially cylindrical geometric shape with a circular base with an opening in its upper portion for coupling to a product dispensing valve, characterized in that it is made of high-density polyethylene.
  • the can for chemical-pharmaceutical-food use particularly for containing pressurized aerosol solutions, designated generally in the two proposed embodiments by the reference numerals 1a and 1b, has a substantially cylindrical geometric shape with a circular base with an opening 2 in its upper portion 3 for coupling to a product dispensing valve 4a or 4b, said opening 2 being radially constricted with respect to the diameter of the upper portion 3.
  • the opening 2 is arranged in the upper end of the can 1a or 1b.
  • the can 1a can be associated with a dispensing valve 4a at the opening 2 by rotary friction welding, so as to form a first embodiment of an aerosol generator, designated generally by the reference numeral 100a.
  • the can 1b can be associated with a dispensing valve 4b at the opening 2 by seaming, so as to form a second embodiment of an aerosol generator, designated generally by the reference numeral 100b.
  • the cans 1a and 1b are made of high-density polyethylene, HDPE in acronym, of the opaque or transparent type.
  • HDPE it is possible to use the ordinary HDPE obtained from oil or Green HDPE, i.e., a high-density thermoplastic polymer obtained from sugar cane and/or environmentally sustainable products.
  • the dispensing valve 4a also has the valve support 5 made of plastic material and more specifically of a plastic material that is compatible with HDPE so as to allow its friction welding.
  • the cans 1a and 1b In order to give mechanical strength to the cans 1a and 1b, they have a lateral surface 6 that is substantially concave along its entire circumferential extension, with a radius of curvature that is variable along the longitudinal axis of the bottle 1a or 1b.
  • such bottom is concave with a frustum-like shape and is provided with a plurality of radial grooves 8 formed at the lower portion 9 of the cans 1a and 1b that is radially external to the bottom 7.
  • One advantage of the can according to the present invention resides in a greater safety for users, by virtue of the fact that the pressurized content is well protected against impacts and sudden depressurizations due to the physical properties of the material chosen and due to the geometry given to the can.
  • the walls of the can compensate the thrust applied by the internal pressure of the aerosol; furthermore, wall thickness is configured to minimize the material used, reducing its overall weight but maintaining a good mechanical strength of the vessel.
  • ESC Endvironmental Stress Cracking
  • the chemical inertia of HDPE ensures that the vessel cannot be subject to oxidation phenomena and denting, differently from traditional white latten and/or aluminum containers.
  • Another advantage of the can according to the invention resides in that the provision of aerosol generators made of Green HDPE entails the absence of oil-derived materials.
  • the aerosol generator made of HDPE can be easily and completely recycled.
  • the range of application of the monoblock made of plastic material, by virtue of the chemical inertia of HDPE, is broad: cosmetics and personal hygiene, food products, haircare, and cleaning products are some of the possible applications.
  • the aerosol generator provided with adjustment valve welded by rotary friction allows to use nitrogen as propellant gas, thus eliminating the use of other more pollutant propellants.
  • a further advantage of the can according to the invention resides in that it is possible to provide a transparent can, allowing the user to visually check the status of the content of the aerosol generator, such as quantity and color.
  • HDPE is capable of giving a better tactile sensation than that offered by the counterparts made of white latten or aluminum.
  • the materials used may be any according to the requirements and the state of the art.
