Abstract
Description
529 877 såsom bakterier, virus, parasiter etc. i avföringen medelst nämnda Urea. 529,877 such as bacteria, viruses, parasites, etc. in the feces by means of said Urea.
Nedan beskrives uppfinningen närmare, delvis i samband med ett på bifogade ritning visade utföringsexempel av uppfin- ningen, där figur la visar en påse enligt uppfinningen i använd- ningsläge - figur lb - ld är en sekvens utvisande hur påsen vecklas ut för att få den i figur l visade formen - figur 2 visar schematiskt ett tvärsnitt av påsen i out- vecklat skick - figur 3 visar påsen enligt figur la uppifrån - figur 4 visar schematiskt ett tvärsnitt av påsens vägg enligt en utföringsform i större skala.The invention is described in more detail below, partly in connection with an exemplary embodiment of the invention shown in the accompanying drawing, in which figure 1a shows a bag according to the invention in use mode - figure 1b - 1d is a sequence showing how the bag is unfolded to get it in figure 1 shows the shape - figure 2 schematically shows a cross section of the bag in an undeveloped condition - figure 3 shows the bag according to figure la from above - figure 4 schematically shows a cross section of the wall of the bag according to a larger scale embodiment.
Nedan beskrives en engàngstoalett enligt uppfinningen avsedd att användas för urinering och defekation.Described below is a disposable toilet according to the invention intended for use in urination and defecation.
Enligt uppfinningen är engångstoaletten i form av en påse l av tillräcklig storlek för att kunna tjäna för att uträtta toalettbehov. I figur la visas en sådan påse i en sidovy. I figur lb visas påsen i ett ihopvikt skick, motsvarande hur konventionella papperspåsar är ihopvikta före användning. I figur lc visas hur en flik 2 vikts ut och i figur ld hur en andra flik 3 vikts ut. Därefter sticker användaren ned en hand i påsen så att även pàsens sidoväggar vecklas ut. I fi- gur 2 visas ett tvärsnitt av en ihopvikt påse. Efter att på- sen utvecklats har den ett ungefärligt utseende uppifrån så- som visas i figur 3.According to the invention, the disposable toilet is in the form of a bag 1 of sufficient size to be able to serve to fulfill toilet needs. Figure 1a shows such a bag in a side view. Figure 1b shows the bag in a folded condition, corresponding to how conventional paper bags are folded before use. Figure 1c shows how a tab 2 is folded out and Figure 1d how a second tab 3 is folded out. Then the user puts one hand in the bag so that the side walls of the bag also unfold. Figure 2 shows a cross section of a folded bag. After the bag has been developed, it has an approximate appearance from above as shown in figure 3.
Enligt uppfinningen är påsen förslutbar efter uträttade be- hov. Påsen är utförd i ett väsentligen gastätt material som är icke permeabelt för vätska. 529 877 Enligt ett väsentligt särdrag hos uppfinningen innehåller på- (CO(NHfl2) aktivera patogena bakterier, virus etc. i avföringen. Enligt sen föreningen Urea i tillräcklig mängd för att in- ett annat väsentligt särdrag hos uppfinningen är påsen utförd i ett biologiskt nedbrytbart material. Dessutom skall ett nedbrytbart material väljas som är icke permeabelt för vätska under den tid som åtgår för att inaktivera patogena bakteri- er, virus, parasiter etc. i avföringen medelst nämnda Urea.According to the invention, the bag can be closed according to fulfilled needs. The bag is made of a substantially gas-tight material which is not permeable to liquid. According to an essential feature of the invention, on- (CO (NH fl2) activates pathogenic bacteria, viruses, etc. in the feces, according to the latter compound Urea in an amount sufficient to incorporate another essential feature of the invention, the bag is made in a biodegradable In addition, a degradable material must be selected which is not permeable to liquid during the time required to inactivate pathogenic bacteria, viruses, parasites, etc. in the faeces by means of said Urea.
En tillräcklig mängd Urea är 2-4 g per påse, men mängden kan avpassas efter behov. Eventuellt kan lämpliga hjälpkemikalier tillsättas för att öka inaktiveringsprocessen.A sufficient amount of Urea is 2-4 g per bag, but the amount can be adjusted as needed. Appropriate auxiliary chemicals may be added to increase the inactivation process.
När Urea kommer i kontakt med avföring bryts den ner till am- moniak och koldioxid, vilket leder till en pH höjning. När hygieniseringsprocessen startas avstannar övrig biologisk ak- tivitet. Detta medför att ingen anaerobisk aktivitet uppträ- der i påsen. Om en anaerobisk aktivitet skulle förekomma i påsen skulle ett problem med gasproduktion kunna uppträda, nämligen att gas utvecklades i sådan mängd att påsen brister.When Urea comes in contact with faeces, it is broken down into ammonia and carbon dioxide, which leads to an increase in pH. When the hygiene process is started, other biological activity stops. This means that no anaerobic activity occurs in the bag. If anaerobic activity were to occur in the bag, a problem with gas production could occur, namely that gas was developed in such an amount that the bag bursts.
Ammoniak är en förening som vid höga koncentrationer inakti- verar mikroorganismer. Samtidigt är kväve i form av ammoniak ett väsentligt gödningsmedel.Ammonia is a compound that inactivates microorganisms at high concentrations. At the same time, nitrogen in the form of ammonia is an essential fertilizer.
Hygieniseringsprocessen torde typiskt ta 9 - 14 dagar.The hygiene process should typically take 9-14 days.
Genom föreliggande engångstoalett uppnås att påsen försluts efter uträttade behov varefter patogena bakterier och virus, parasiter etc. inaktiveras innan påsens väggmaterial ned- bryts. När väggmaterialet nedbrutits i sådan grad att avfö- ringen kan läcka ut är avföringen således ofarlig och kan användas som gödningsmedel i odlingar. 529 877 Enligt en föredragen utföringsform har påsen en längd som är tillräcklig för att påsen l skall kunna tillknytas med en knut om egen part vid påsens öppningsområde.Through the present disposable toilet, it is achieved that the bag is closed according to fulfilled needs, after which pathogenic bacteria and viruses, parasites, etc. are inactivated before the wall material of the bag is broken down. When the wall material has decomposed to such an extent that the faeces can leak out, the faeces are thus harmless and can be used as fertilizer in crops. According to a preferred embodiment, the bag has a length which is sufficient for the bag 1 to be able to be tied with a knot about its own part at the opening area of the bag.
Enligt en alternativ föredragen utföringsform har påsen en längd tillräcklig för att påsen l skall kunna tillknytas med ett vid påsen fästat snöre 4 eller motsvarande vid påsens l öppningsområde. Ett snöre 4 antyds med streckade linjer i figur l.According to an alternative preferred embodiment, the bag has a length sufficient for the bag 1 to be able to be connected with a string 4 attached to the bag or equivalent at the opening area of the bag 1. A string 4 is indicated by dashed lines in figure 1.
Enligt ett föredraget utförande är påsen utförd i ett materi- al ur gruppen polysackarider, exempelvis stärkelse, amylopek- tin, amylos, cellulosaderivat, kitin/kitosan, alginat, kara- genan och alifatiska polyestrar, exempelvis poly-Z-kaprolak- ton, polylaktid, polyglykolid, polyadipinsyra och polyhydrox- ialkanoater. Även proteiner samt polyolefiner, exempelvis po- lyeten, med lämpliga kända tillsatser kan också användas.According to a preferred embodiment, the bag is made of a material from the group of polysaccharides, for example starch, amylopectin, amylose, cellulose derivatives, chitin / chitosan, alginate, carrageenan and aliphatic polyesters, for example poly-Z-caprolactone, polylactide , polyglycolide, polyadipic acid and polyhydroxyalkanoates. Proteins and polyolefins, for example polyethylene, with suitable known additives can also be used.
Enligt en utföringsform är påsen utförd i ett material som är ett laminat av två eller flera av nämnda material.According to one embodiment, the bag is made of a material which is a laminate of two or more of said materials.
Enligt en annan utföringsform är påsen utförd i ett material som är en sampolymer och/eller polymerblandning av två eller flera av nämnda material.According to another embodiment, the bag is made of a material which is a copolymer and / or polymer mixture of two or more of said materials.
Påsen kan vara utförd som en kombination av laminat, sampoly~ merer och/eller polymerblandningar.The bag may be made as a combination of laminates, copolymers and / or polymer blends.
I figur 4 visas illustrationsvis ett tvärsnitt genom påsens vägg. Skiktet betecknat med siffran 5 är en fuktspärr. Skik- tet betecknat 6 är en gasspärr och skiktet betecknat 7 en fuktspärr.Figure 4 illustratively shows a cross section through the wall of the bag. The layer denoted by the number 5 is a moisture barrier. The layer designated 6 is a gas barrier and the layer designated 7 a moisture barrier.
Enligt en föredragen utföringsform är Urea applicerat på vä- sentligen hela påsens insida. Härvid bildar urea ett till- 529 877 räckligt tjockt skikt på pàsens insida såsom illustreras i figur 4 med skiktet 8 för att ovan nämnda inaktivering skall uppnås.According to a preferred embodiment, Urea is applied to substantially the entire inside of the bag. In this case, urea forms a sufficiently thick layer on the inside of the bag as illustrated in Figure 4 with the layer 8 in order to achieve the above-mentioned inactivation.
Enligt en alternativ utföringsform förefinns Urea i påsen, exempelvis i form av ett granulat eller ett pulver.According to an alternative embodiment, Urea is present in the bag, for example in the form of a granulate or a powder.
Ovan har ett antal utföringsexempel beskrivits. Det är dock uppenbart att påsens form kan varieras till att ha ett cirku- lärt tvärsnitt med en trattliknande övre del i utvikt skick.A number of embodiments have been described above. However, it is obvious that the shape of the bag can be varied to have a circular cross-section with a funnel-like upper part in the unfolded condition.
Vidare kan den trattliknande övre delen vara så vid att an- vändaren kan hålla om påsen och vika ned den övre delen av tratten över den hand med vilken användaren håller påsen.Furthermore, the funnel-like upper part can be such that the user can hold the bag and fold down the upper part of the funnel over the hand with which the user holds the bag.
Det är uppenbart att påsen kan ha vilken lämplig form som helst för dess ändamål, varför de ovan angivna formerna en- dast är exemplifierande utföringsformer.It is obvious that the bag can have any suitable shape for its purpose, so the above-mentioned shapes are only exemplary embodiments.
Dessutom kan pàsens hållfasthet varieras genom väggtjockle- ken. Påsen kan också ha en varierande väggtjocklek, där exem- pelvis den del av påsen som är öppen och om vilken användaren håller har en tjockare väggtjocklek än den övre delen av pà- Sen.In addition, the strength of the bag can be varied by the wall thickness. The bag can also have a varying wall thickness, where, for example, the part of the bag which is open and which the user holds has a thicker wall thickness than the upper part of the bag.
Föreliggande uppfinning skall därför inte anses begränsad till de ovan angivna utföringsexemplen, utan kan varieras inom dess av bifogade patentkrav angivna ram.The present invention should therefore not be construed as limited to the above-mentioned embodiments, but may be varied within the scope of the appended claims.
