The technical field

The present invention relates to an absorbent article such as sanitary napkins, daily strip, protective equipment in case of incontinence and diapers, which include the element carrier containing moisture sensitive additive, such as bacterial composition.

The prior art inventions

The urogenital region hides a complex microbial ecosystem that includes more than 50 different bacterial species (Hill et al., Scand. J. Urol. Nephrol. 1984; 86 (suppl.) 23-29). The dominant species in this area for Mature women are producing lactic acid bacteria belonging to the genusLactobacillus. These producing lactic acid representatives are important for maintaining a healthy microbial flora in these areas and act as probiotic bacteria with antagonistic effects on pathogenic microbial species. Producing lactic acid bacteria inhibit the growth and colonization of other microorganisms, capturing the suitable niches for colonization, forming biofilms and competing for available nutrients, thus preventing the colonization of harmful microorganisms. Also the production of hydrogen peroxide, specific inhibitory substances, such as bacteriocins and organic acids on the tea lactic acid and acetic acid), to lower pH, prevents colonization by other microorganisms.

Microbial ecosystem healthy individual can be impaired in the use of antibiotics during hormonal changes such as during pregnancy or with the use of contraceptives with estrogen during menstruation, after menopause, people suffering from diabetes, etc. Also microorganisms can spread from the anus to the urogenital region, thus causing infection. This leads to disturbances in the normal microbial flora and makes the individual susceptible to microbial infections that cause vaginitis, urinary tract infection and common skin infections. Microorganisms normally associated with these types of infections, belong to the speciesEscherichia, Enterococcus, Psedomonas, Proteus, Klebsiella, Streptococcus, Staphylococcus, GardnerellaandCandida. Women are particularly at risk due to their shorter the distance between the anus and urinary ways; especially at risk are young women who do not yet have well-developed flora in the urogenital region, and older women who had no protective flora.

One way to reduce the problems associated with infections, described above, is good personal hygiene. However, excessive use of detergents not only reduces the number is harmful microbes but can damage the beneficial microbial flora, again changing it so that it becomes susceptible to pathogenic species, which create colonies and cause infections.

Alternatively, it was found that the use of producing lactic acid bacteria in the urogenital area and the skin to displace pathogenic species and help restore and maintain the beneficial microbial flora in these areas is a good tool for the treatment and prevention of microbial infections.

It has been suggested that producing lactic acid bacteria could be eliminated by absorbent products such as diapers, sanitary pad, protective equipment in case of incontinence, pads and tampons, as described, for example, in WO 92/13577, WO 97/02848, WO 99/17813, WO 99/45099 and WO 00/35502.

The main problem with the provision of products intended for use for the transmission of producing lactic acid bacteria is that bacteria need to survive during transport and storage of products. Producing lactic acid bacteria quickly lose viability in sub-humid conditions, and therefore, it is important that the bacteria were not exposed to uncontrolled moisture. Under “semi-moist” conditions meant that the water activity(a _w) is between approximately 0.2 and approximately 0.9m. One way to partially overcome this problem, in absorbent products, provided with producing lactic acid bacteria, was to supply products with bacteria, drying of these products to remove most of the moisture and the conclusion products impervious to moisture packaging (WO 99/17813; EP B1 1210277). However, since the absorbent product is completely packaged together with moisture sensitive bacteria, it is necessary, as stated above, to dry the specified absorbent product to a high degree. The traditional processes for absorbent products, it is very difficult to achieve. It is also not flexible solution, since, once the product is dried, it should quickly be enclosed in impermeable to moisture packing before the moisture will begin to act on producing lactic acid bacteria. In addition, because these impervious to moisture packaging are made from expensive film, these kinds of larger packages are quite expensive.

An alternative way to protect bacteria from moisture was in the dispersion of bacteria on the hydrophobic substance (see, for example, US 4518696, WO 92/13577, WO 02/28446), which is due to its hydrophobic nature prevents access of moisture to the attached bacterial cells. is this case, the problem is when folding and packaging of the product hydrophobic substance in which the dispersed bacteria, is attached to the packaging or smeared on the product undesirable way that makes the product sloppy. If a hydrophobic substance smeared on the top layer, it can also have a negative effect on adsorption capacity due to clogging of pores on the top layer. The desired effect may also be reduced, since some of the bacteria will disappear from the package when removing a package or alternative will end on the location on the product, where they are not in direct contact with the urogenital area in the application.

Therefore, there is still a need to develop improved ways to protect moisture-sensitive additives, such as producing lactic acid bacteria, to ensure that this additive will not harm or she will not be destroyed, and which will also ensure that the product properties are preserved. In addition, there is a need for the development of industrial processes that are efficient and less costly.

Definitions

The term “absorbent article” refers to articles which are placed directly opposite the skin of the user for adsorption and preservation of physiological fluids such as urine, faeces and menstrual fluid. The invention relates mainly to disposable absorbent products, which means products that are not designed to be laundered or otherwise for the recovery or re-use as absorbent product after application. Examples of disposable absorbent articles include feminine hygiene products such as sanitary napkins, pads and sanitary panties; diapers and diapers in the form of shorts for babies and adults with incontinence; strip when incontinence; liners for diapers and such.

Under “moisture-sensitive additives” refers to additives that are designed to facilitate the effect and function of the product in some way and which properties can be reduced when they are exposed to unregulated levels of moisture, for example, during storage. Examples of such moisture-sensitive additives are moisture sensitive bacterial compositions, such as La is tomacelli, and odor inhibiting additives, such as zeolites and silica.

Under “probiotic composition” or “bacterial composition” means a composition comprising probiotic bacteria, i.e. bacteria that have the ability to restore the natural microbial flora of the host body.

“Water activity” a_wmeasures the vapor pressure generated by the moisture present in the absorbent product.

a_w=p/p_s,where

p: partial pressure of water vapor on the surface of the product

p_s: saturated vapor pressure or partial pressure of water vapor above pure water at the product temperature.

Water activity reflects the active part of moisture content or part, which under normal circumstances can be changed between a product and its environment.

Water activity is usually determined at static equilibrium. Under these conditions the partial pressure of water vapor (p) on the surface of the product is equal to the partial pressure of water vapor in the intermediate environment of the product. Any exchange of moisture between the product and its environment leads to the distinction between these two partial pressures.

By “dispersion” is meant a mixture of at least two phases, which are nearest origami or partially soluble in each other, in which one phase forms solid particles, liquid droplets or gas bubbles in the other phase.

Preferred “producing lactic acid bacteria for the purpose of the present invention include bacteria of the speciesLactobacillus, LactococcusandPediococcus.Preferably used is selected bacteria are bacteria of the speciesLactococcus lactis, Lactobacillus acidophilus, Lactobacillus curvatusorLactobacillus plantarum.More preferably, the bacterial strain selected fromLactobacillus plantarum.Even more preferably producing lactic acid bacteria areLactobacillus plantarum931 (deposition no. (DSMZ): 11918).

By “impermeable to water vapor” layer of material refers to the material layer, the proof of which is so high that the element-carrier consisting of a specified layer of material that will not allow the penetration of more moisture than the one in which the absorption of the active moisture sensitive additive is present in the element carrier, will substantially maintain their properties. This means that the element carrier may have the highest WVTR (transmission rate of water vapor), is equal to 6 g/m²/24 h in accordance with ASTME 398-83 at 37.8°C (100°F) and 90% relative humidity, preferably not more than 4 g/m²/24 h and more preferably not more than 2 g/m²/24 HR, sales is more preferably not more than 1 g/m ²/24 h and even more preferably not more than 0.1 g/m²/24-hours-Applied layer of material is also preferable to protect moisture sensitive additive in such a way that these supplements will maintain its effect for at least 6 months and preferably for 9 months at 23°C (73.4°F) and 50% relative humidity after the packing date.

Fig illustrates the layer 12, 13 material as a three-layer laminate having a protective waterproof layer 16, which is intended to lie as an external protective layer that is impermeable to water vapor of the intermediate layer 15 and the inner sealing layer 14, is intended to refer to the moisture sensitive additive.

The layer 12, 13 of the material, i.e. the laminate illustrated in Fig, it would be preferable to have a thickness equal to 10-400 μm, preferably 20-300 μm.

Material intended for education impermeable to water vapor layers 12, 13 of the material is often expensive, and preferably applies the possible thin layer of material, while still required strength properties. To obtain the layer 12, 13 of a material which has good wear resistance and can be easily compacted, you can use less expensive material as the outer protective wear-resistant layer 16 and/or as an internal sealing layer 14. For example, the layer 12, 13 material may include an inner layer 14 Lamy is ATA, which makes it possible to obtain a good seal 11, for example, polyolefins, copolymers of ethylene and vinyl acetate, copolymers of ethylene and ethyl acrylate, copolymers of ethylene and butyl acrylate, polyethyleneteraftalat, polyethylenterephthalat, polyamides, ionomers or wax, an intermediate layer 15 of the laminate, which consists of a material having good permeability to water vapor, which is chosen from materials of aluminum, aluminum oxide, silicon oxide, polyethylene, polypropylene, polyesters, polyvinyl chloride, polyvinylchloride, cyclic olefin copolymers, polyolefins, metal-containing polyolefins, polyamide (nylon) or plastic laminates with ceramic barrier and wear-resistant outer layer 16, such as polyesters, polyethylene or polypropylene. The layer 12, 13 material may consist of from one to ten layers of a laminate of different materials. Unlimited examples of the laminates are high-barrier aluminum laminates and high-barrier laminates that do not contain aluminum, Ceramis^®both from ALCAN Cramlington Ltd.

Suitable sealing means are, for example, ultrasonic welding, heat sealing, heat sealing at low temperatures or cold seal. In the case of a cold seal or heat seal at low temperatures UE is ethnically layer, such as, for example, polyethyleneteraftalat, polyethylenterephthalat or wax, is applied on the sealing side of the element carrier. This sealing layer can be applied to the entire surface or only where there should be a seal, the so-called boundary surface. To improve the heat seal layers of the laminate that is used as impermeable to water vapor of the material layer and the inner laminate “welded” layer will normally include low density polyethylene (LDPE), optional copolymerizable with butyl acrylate or vinyl acetate. This makes possible the implementation of the heat seal at high speeds. When the seal of the specified element of the carrier should be pressed together, the sealing material around the specified volume, as in the case of all methods of compaction. This is achieved by using cold, hot or slightly heated rollers or welding tongs and should be carried out under pressure and temperature and for a given period of time, which correspond to the selected material and will lead to the intended tight seal and seal strength.

The layers of material can also be glued together with the formation of the specified compaction.
