Abstract
Synthetic material containing at least one heat-cured polymer and an impregnated filler which has, on contact, an antiseptic and/or antioxidant action on a fluid product, in which the filler is an organic filler impregnated with at least one water-soluble antiseptic agent and/or with at least one water-soluble antioxidant agent. The antiseptic and/or antioxidant agents are capable of being released when the synthetic material is in contact with a fluid product and of at least partially preventing the degradation of the fluid product by microorganisms or by oxygen.
Claims23
A synthetic polymeric material comprising a mixture of a heat-cured urea-formaldehyde resin and a particulate organic filler selected from the group consisting of wood powder, wood sawdust, cellulose, starch, carragenate gum, an alginate, a xanthan, a scleroglucan and mixtures thereof, said particulate organic filler being impregnated with an antiseptic agent selected from the group consisting of a water-soluble copper salt, a water-soluble zinc salt and a water-soluble silver salt.
A container for dispensing a fluid product degradable by microorganisms or atmospheric oxygen, said container provided with a dispensing head having a dispensing channel through which said fluid product is dispensed, said dispensing channel comprising a polymeric material comprising a mixture of heat-cured urea-formaldehyde resin and a particulate organic filler selected from the group consisting of wood powder, wood sawdust, cellulose, starch, carragenate gum, an alginate, a xanthan, a scleroglucan and mixtures thereof, said particulate organic filler being impregnated with a water-soluble antiseptic agent, a water-soluble antioxidant agent and a mixture thereof.
A dispensing channel in a dispensing head of a container for dispensing through said dispensing channel a fluid product degradable by microorganisms or atmospheric oxygen, said dispensing channel comprising a polymeric material comprising a mixture of heat-cured urea-formaldehyde resin and a particulate organic filler selected from the group consisting of wood powder, wood sawdust, cellulose, starch, carragenate gum, an alginate, a xanthan, a scleroglucan and mixtures thereof, said particulate organic filler being impregnated with a water-soluble antiseptic agent or a water-soluble antioxidant agent or a mixture thereof.
