Digitalni tampon, zlasti higienski tampon, po izbiri aplikatorski tampon ter naprava in postopek za izdelavo tovrstnega tamponaDigital buffer, in particular hygiene buffer, optionally applicator buffer and device and process for making such buffer
Predmetni izum se nanaša na tampon, še zlasti na higienski tampon. Po Mednarodni patentni klasifikaciji so tovrstni izumi v okviru tekočih življenjskih potrebščin razvrščeni na področje medicine in higiene i v okviru teh na področje tamponov, še zlasti menstruacijskih higienskih tamponov in pribora zanje.The present invention relates to a tampon, in particular a hygienic tampon. According to the International Patent Classification, such inventions are classified in the field of medicine and hygiene and in the field of tampons, in particular, menstrual hygiene tampons and accessories, in the context of liquid consumer goods.
Pri tem je izum osnovan na problemu, kako tamponu, kakršnega je možno izdelati iz enakih surovin, na enakih strojih in v osnovi po enakih tehnoloških korakih kot doslej znane komercialno zanimive tampone, izboljšati stabilnost, namreč upogibno in uklonsko trdnost, obenem pa zagotoviti postopno in optimalno spreminjanje njegove oblike po njegovem omočenju, pri čemer naj bi bila v primerjavi z doslej znanimi tamponi penetracija tekočine v vzdolžni smeri temu ustrezno upočasnjena in pri čemer naj bi bila možnost odtekanja absorbirane tekočine iz omočenega tampona znatno manjša kot doslej.The invention is based on the problem of how a tampon, such as can be made from the same raw materials, on the same machines and basically following the same technological steps as previously known commercially interesting tampons, to improve stability, namely flexural and tensile strength, while ensuring gradual and optimally changing its shape after wetting, whereby the penetration of the fluid in the longitudinal direction is slowed down compared to the known tampons so far, and the absorption of the absorbed fluid from the wetted tampon is expected to be significantly less than before.
Tampon, kakršen je opisan v DE 0 422 660, sestoji iz netkanega vlaknastega surovca, ki je dobljen z navijanjem netkanega vlakninskega traku okoli vzdolžne osi, s čimer se ustvari vsaj približno valjast preoblikovanec, ki se ga nato s stiskanjem s pomočjo ustreznih Čeljusti v radialni smeri, npr. s pomočjo stiskalne priprave po DE 19 825 877, oblikuje v tampon. Tak tampon je v osnovi še vedno valjaste oblike, vendar ima na površini vtisnjene radialno navznoter usmerjene žlebove, ki obenem po omenjeni zunanji površini potekajo v vzdolžni smeri tampona oz. vzporedno z omenjeno vzdolžno oz. osrednjo osjo tampona. Tovrstni tamponi so v stroki znani pod imenom »digitalni« tamponi. Med vsakokrat sosednjima žleboma je tako na voljo po eno rebro, pri čemer zunanji obod omenjenih reber določa zunanji premer tampona, dno omenjenih žlebov pa določajo premer razmeroma komprimiranega jedra tampona. Z naknadnim, razmeroma blagim stiskanjem tampona v območju omenjenih reber dosežejo konveksnost oz. usločenost bočnih površin omenjenih reber, tako da se bočni površini vsakokrat sosednjih reber dotikata druga druge in v bližini omenjenega komprimiranega jedra formirata cevast, z vzdolžno osjo tampona vzporedno potekajoč prostor. Tovrstna zasnova naj bi privedla do ugodnih učinkov, in sicer do povečanja uklonske oz. upogibne trdnosti tampona in še zlasti tudi do povečanja specifične vpojnosti in hitrosti absorpcije v vzdolžni smeri tampona. Stabilnost tampona je odločilnega pomena v pogledu zaupanja s strani uporabnika in še zlasti pride do izraza med vstavljanjem tampona. Hitrost absorpcije je sicer v omenjenem viru izpostavljena kot pomembna značilnost, kateri pa v praksi uporabnice ne posvečajo praktično nikakršne pozornosti, ker med dejansko uporabo ključnega pomena druge lastnosti. Tako je še posebej pomembna specifična vpojnost, namreč količina tekočine, ki jo je tampon zmožen absorbirati na enoto teže materiala tampona, še zlasti pa tudi način preoblikovanja tampona med omočenjem. Med omočenjem tampona po EP 0 422 660 na enem koncu je • · omenjeni konec sicer zelo hitro zmožen sprejeti razmeroma veliko količino tekočine, pri čemer pa se tampon na omenjenem koncu tudi naglo razširi oz. razpre v obliki troblje. To ima za posledico, da v primeru prestrezanja večje količine tekočine, npr. ob hudi menstruaciji, pri tovrstnem tamponu obstoji možnost izcejanja tekočine iz hitro razširjenega konca.The tampon as described in DE 0 422 660 consists of a non-woven fibrous blank obtained by winding a non-woven fiber web about a longitudinal axis, thereby creating at least approximately a cylindrical mold, which is then compressed by means of suitable jaws in a radial directions, e.g. by means of a compression device according to DE 19 825 877, forms into a tampon. Such a tampon is basically cylindrical in shape, but has radially inward grooves impressed on the surface, which at the same time extends along said outer surface in the longitudinal direction of the tampon. parallel to said longitudinal or the central axis of the tampon. Such tampons are known in the art as "digital" tampons. Thus, one rib is available between adjacent grooves, with the outer circumference of said ribs determining the outer diameter of the buffer and the bottom of said grooves determining the diameter of the relatively compressed core of the buffer. Subsequent, relatively gentle compression of the tampon in the region of said ribs achieves convexity. bending of the lateral surfaces of said ribs so that the lateral surfaces of each adjacent ribs touch each other and form a tubular space parallel to the longitudinal axis of the tampon in the vicinity of said compressed core. Such a design should lead to favorable effects, namely increasing the clearance or the flexural strength of the tampon and, in particular, the increase of the specific absorption and absorption rate in the longitudinal direction of the tampon. The stability of the tampon is crucial in terms of user confidence and, in particular, occurs when inserting the tampon. Absorption rate is, however, highlighted in this source as an important feature, but in practice, users pay virtually no attention to it, since other features are crucial during actual use. Of particular importance is the specific absorbency, namely the amount of fluid that the tampon is able to absorb per unit weight of the tampon material, and in particular the way the tampon is transformed during wetting. While wetting the buffer according to EP 0 422 660 at one end, • the said end is able very quickly to absorb a relatively large amount of fluid, but the buffer at this end also expands or swells rapidly. opens in the form of a trumpet. This results in the fact that in the case of an intercept, a larger amount of fluid, e.g. in the case of severe menstruation, this type of swab has the potential to drain fluid from a rapidly expanding end.
Razen tampona je v EP 0 422 660 opisana tudi naprava in postopek za izdelavo tampona prej opisane vrste. Postopek izdelave je bil v grobem obrazložen v opisu same zasnove tampona, naprava pa poleg omenjenih čeljusti za radialno vtiskanje žlebov obsega še sredstvo za ustvarjanje temu sledečega blagega pritiska na zunanje površine reber, pri čemer omenjeno sredstvo predstavlja konusna matrica, skozi katero po izdelavi reber in žlebov iztisnejo tampon. Kot rečeno, uporaba tovrstnega postopka in tovrstne naprave vodi do produkta s prej omenjenimi pomanjkljivostmi.In addition to the tampon, EP 0 422 660 also describes the device and process for making the tampon of the type described above. The manufacturing process has been broadly explained in the description of the design of the tampon itself, and the device includes, in addition to said jaws for radially grooving grooves, a means for creating the following slight pressure on the outer surfaces of the ribs, said means being a conical die through which after the ribs are made and grooves squeeze out the tampon. That being said, the use of this type of process and this kind of device leads to a product with the aforementioned disadvantages.
Z namenom, da bi vpojnost še povečali, je bil razvit tampon, je v WO 01/076357 A3 predlagan tampon, ki načeloma sestoji iz enakega preoblikovanca in iz enakega gradiva kot predhodno opisan tampon, na katerega površini so na praktično enak način s stiskanjem v radialni smeri oblikovana omenjena rebra in žlebovi. Vendar pa v tem primeru omenjena rebra ne potekajo v vzdolžni smeri tampona, marveč spiralno oz. v obliki vijačnice, ki se vije po njegovi površini pod določenim razmeroma majhnim kotom glede na vzdolžno os tampona. Z omenjenim ukrepom podaljšajo dolžino reber in žlebov, s tem pa naj bi zmanjšali možnost izcejanja tekočine iz omočenega tampona. Izdelava tovrstnih tamponov je znatno bolj zapletena od izdelave tamponov, pri katerih rebra in žlebovi potekajo vzporedno z vzdolžno osjo tampona.In order to increase the absorbency, a tampon was developed, in WO 01/076357 A3, a tampon is proposed, consisting essentially of the same transformer and of the same material as the tampon previously described, in which the surfaces are practically the same by pressing in radial directions formed said ribs and grooves. However, in this case, the said ribs do not extend in the longitudinal direction of the tampon, but rather spiral or. in the form of a helix that curves over its surface at a certain relatively small angle with respect to the longitudinal axis of the tampon. This measure extends the length of the ribs and grooves, thus reducing the possibility of fluid leaking from the wetted pad. The manufacture of such tampons is significantly more complicated than the manufacture of tampons, in which the ribs and grooves run parallel to the longitudinal axis of the tampon.
Še nadalje so na področju uporabe tamponov znane priprave za embaliranje in vstavljanje tamponov, namreč takoimenovani tamponski aplikatorji.In the field of the use of tampons, there are still known devices for the packaging and insertion of tampons, namely the so-called tampon applicators.
Klasičen aplikator, kakršen je npr. opisan v US 3,643,661 in sestoji iz tampona, ki je vstavljen v zunanji cevi, v kateri je - gledano v smeri vstavljanja tampona - za omenjenim tamponom prav tako vstavljena notranja cev, katere zunanji premer približno ustreza notranjemu premeru zunanje cevi oz. premeru tampona, tako da je s premikom notranje cevi v smeri proti tamponu možno slednjega iztisniti ven iz zunanje cevi in ga pri tem vstaviti in namestiti v ustrezen položaj. Problem tovrstnih aplikatorjev je neprikladnost zaradi precejšnje dolžine.A classic applicator, such as described in U.S. Pat. No. 3,643,661 and consisting of a tampon inserted in an outer tube in which, viewed in the direction of insertion of the tampon, an inner tube is also inserted behind said tampon whose outer diameter approximately corresponds to the inner diameter of the outer tube, or. the diameter of the tampon, so that by moving the inner tube in the direction of the tampon, it is possible to push the tampon out of the outer tube and insert and place it in the appropriate position. The problem with such applicators is the inappropriateness due to their considerable length.
Sodobnejši, krajši in prikladnejši aplikatorji so takoimenovani »kompaktni« aplikatorji, ki v osnovi prav tako sestojijo iz notranje cevi, ki je vstavljena v zunanji cevi, kot tudi iz tampona, ki je spočetka vstavljen v svetlini notranje cevi in v nekaterih primerih, npr. pri aplikatorju po EP 1 704 841 z digitalnim tamponom ali pri aplikatorju po US 4,479,791 s klasičnim stisnjenim tamponom brez žlebov in reber na zunanji površini v takem položaju držan z ustreznimi zadrževalnimi sredstvi, ki so na voljo v svetlini zunanje cevi neposredno ob vstavljalnem koncu. S premikom notranje cevi v smeri vstran od omenjenega vstavljalnega konca zadrževalna sredstva zadržijo tampon v izhodiščnem položaju, pri čemer tampon izstopi iz svetline notranje cevi, vendar ostane v notranjosti zunanje cevi. Z nadaljnjim premikom notranje cevi v smeri proti tamponu oz. vstavljalnemu koncu notranja cev naleže na tampon in ga iztisne iz notranjosti zunanje cevi na prosto. Zaradi boljšega sodelovanja med tamponom in omenjenimi zadrževalnimi sredstvi, je v takih primerih prednostno, če je tampon na svojem vstavljalnem koncu odebeljen in opremljen z gobasto glavo oz. glavo, ki je podobna glavi kovice. Tak tampon je opisan npr. v EP 0 355 396. V nekaterih primerih, ko je v prav tako kompaktnem tamponskem aplikatorju zadrževanje in iztiskanje tampona v smeri vstavljanja rešeno drugače (npr. US 4,291,694), je formiranje odebeljene glave na tamponu nepotrebno.More modern, shorter and more convenient applicators are the so-called "compact" applicators, which basically also consist of an inner tube inserted into the outer tube, as well as a tampon initially inserted in the brightness of the inner tube and in some cases, e.g. in the case of an applicator according to EP 1 704 841 with a digital tampon or in an applicator according to US 4,479,791 with a classic compressed tampon without grooves and ribs on the outer surface in such a position, held by the appropriate retaining means available in the brightness of the outer tube directly at the insertion end. By moving the inner tube away from said insertion end, the retaining means retain the buffer in its initial position, leaving the buffer out of the brightness of the inner tube but remaining inside the outer tube. By further moving the inner tube in the direction of the tampon or. the insertion end of the inner tube attaches to the tampon and extrudes it from the outside of the outer tube to the open. In order to better cooperate between the buffer and said retaining means, it is preferable in such cases if the buffer is thickened at its insertion end and provided with a sponge head or a spongy head. a head similar to a rivet head. Such a buffer is described e.g. in EP 0 355 396. In some cases, when the retention and extrusion of the tampon in the direction of insertion is resolved otherwise (e.g., US 4,291,694) in a compact compact applicator, the formation of a thickened head on the tampon is unnecessary.
Iz povedanega je razvidno, da so omenjeni tamponi, od katerih je praktično vsak uporabljiv tudi brez aplikatorja, lahko uporabljeni tudi kot aplikatorski tamponi in kot taki predstavljajo del aplikatorja oz. aplikatorskega sklopa, pri čemer so v kontekstu pričujočega izuma v enem ali druge primeru izpostavljeni identični problematiki in podvrženi enotni izumiteljski zamisli, s katero je rešen kateri od problemov, ki se s tem v zvezi pojavljajo.From the above it is evident that the said tampons, each of which is practically usable even without the applicator, can also be used as applicator tampons and as such represent a part of the applicator or. the applicator assembly, wherein in the context of the present invention, in one case or another, they are exposed to identical problems and are subject to a single inventive idea which solves any of the problems that arise in this connection.

Tampon 1 po izumu sestoji iz vpojnega netkanega vlaknastega gradiva, ki prednostno sestoji iz naravnih vlaken, npr. na osnovi celuloze, ali po izbiri iz kombinacije naravnih vlaken in sintetičnih vlaken. Tampon 1 je izveden simetrično glede na vzdolžno os 100 in obsega v smeri vstavljanja prednji oz. vstavljalni konec 111 in zadnji konec 112, na katerem je tampon 1 na znan način opremljen z vrvico 113.Tampon 1 according to the invention consists of an absorbent non-woven fibrous material, preferably consisting of natural fibers, e.g. cellulose-based, or optionally from a combination of natural fibers and synthetic fibers. Tampon 1 is made symmetrically with respect to the longitudinal axis 100 and extends in the direction of insertion of the front or front. the insertion end 111 and the rear end 112, on which the pad 1 is provided in a known manner with a string 113.
Tampon 1 po izumu obsega obris oz. prečni presek, ki je v dveh med seboj pravokotnih ravninah sploščen in torej spominja na kvadrat z zaokroženimi vogalnimi območji. Na zunanji površini tampona 1 je vidnih osem po obodu enakomerno razporejenih in v vzdolžni smeri tampona 1, t.j. vzporedno z vzdolžno osjo 100 potekajočih žlebov 11, 12, 13, 14 15, 16, 17, 18. Omenjeni žlebovi 11, 12, 13, 14 15, 16, 17, 18 v splošnem potekajo preko vsaj dela celotne dolžine L tampona 1. Pri tamponu po Sl. 1 žlebovi 11, 12, 13, 14 15, 16, 17, 18 potekajo preko celotne dolžine L tampona, pri nekaterih od možnih izvedb (npr. Sl. 3 in 4 pa zgolj preko pretežnega dela dolžine L tampona 1.Tampon 1 according to the invention comprises an outline or an outline. a cross-section that is flattened in two orthogonal planes and thus resembles a square with rounded corner areas. On the outer surface of tampon 1, eight perimeter are visible evenly spaced and in the longitudinal direction of tampon 1, i.e. parallel to the longitudinal axis 100 of the running grooves 11, 12, 13, 14 15, 16, 17, 18. Said grooves 11, 12, 13, 14 15, 16, 17, 18 generally extend over at least part of the entire length L of tampon 1. In the tampon of FIG. 1 grooves 11, 12, 13, 14 15, 16, 17, 18 extend over the entire length L of the tampon, and in some of the possible embodiments (e.g., Figs. 3 and 4, only through the greater part of the length L tampon 1.
Pri tem so omenjeni žlebovi 11, 12, 13, 14 15, 16, 17, 18 tako zasnovani, da so štirje žlebovi 11, 13, 15, 17, ki se nahajajo v dveh med seboj pravokotnih skozi vzdolžno os 100 tampona 1 potekajočih ravninah, dimenzijsko, in sicer vsaj v pogledu širine BI in globine Tl, med seboj vsaj približno usklajeni, prednostno pa enaki. Preostali štirje žlebovi 12, 14, 16, 18, ki se nahajajo v med seboj pravokotnih in glede na prej omenjeni ravnini pod kotom 45° okoli omenjene osi 100 zasukanih skozi vzdolžno os 100 potekajočih ravninah so dimenzijsko, in sicer vsaj v pogledu širine B2 in globine T2, med seboj prav tako vsaj približno usklajeni, prednostno pa enaki, hkrati pa se njihove dimenzije B2, T2 razlikujejo od prej omenjenih žlebov 11, 13, 15, 17.Said grooves 11, 12, 13, 14 15, 16, 17, 18 are so designed that the four grooves 11, 13, 15, 17, which are located in two perpendicularly through the longitudinal axis 100 of the tampon 1 of the running planes , dimensionally, at least in terms of BI width and Tl depth, at least approximately aligned, preferably identical. The remaining four grooves 12, 14, 16, 18, which are perpendicular to each other and with respect to the aforementioned planes at an angle of 45 ° about said axis 100 rotated through the longitudinal axis 100 of the planes, are dimensional, at least in terms of width B2 and the depths of T2, which are also at least approximately aligned, preferably identical, and at the same time their dimensions B2, T2 differ from the previously mentioned grooves 11, 13, 15, 17.
V prikazanem primeru so na zunanji površini tampona 1 na voljo žlebovi 11, 13, 15, 17 širine BI, ki so vtisnjeni do globine Tl, kot tudi žlebovi 12, 14, 16, 18 širine B2, ki so vtisnjeni do globine T2. Pri tem je vsakokraten žleb 11, 13, 15, 17 širine BI, kije vtisnjen do globine Tl, razporejen med dvema sosednjima žleboma 12, 14, 16, 18 širine B2, od katerih je vsak vtisnjeni do globine B2, ali obratno.In the example shown, grooves 11, 13, 15, 17 of BI width imprinted to the depth Tl are available on the outer surface of tampon 1, as well as grooves 12, 14, 16, 18 of width B2 imprinted to T2 depth. In this case, each groove 11, 13, 15, 17 of width BI, which is imprinted to a depth Tl, is arranged between two adjacent grooves 12, 14, 16, 18 of width B2, each of which is imprinted to depth B2, or vice versa.
Strokovnjaku bo razumljivo, da je na Sl. 1 ponazorjena idealizirana oblika obrisa oz. prečnega preseka tampona 1, ki je določena z obliko in dimenzijami stiskalnih čeljusti 21, 22, 23, 24, 25, 26, 27, 28 stiskalne priprave 20 (Sl. 2) Dejanske izmere žlebov 11, 12, 13, 14 15, 16, 17, 18 so lahko odvisne od vsaj nekaterih parametrov kot npr. od vlakninske sestave preoblikovanca 10, pritiska čeljusti 21, 22, 23, 24, 25, 26, 27, 28 in tudi od samih izmer BI, Tl; B2, T2 čeljusti 21, 22, 23, 24, 25, 26, 27, 28 priprave 20.It will be appreciated by those skilled in the art that in FIG. 1 illustrates an idealized outline or outline. of the cross-section of the tampon 1, determined by the shape and dimensions of the compression jaws 21, 22, 23, 24, 25, 26, 27, 28 of the compression device 20 (Fig. 2). The actual dimensions of the grooves 11, 12, 13, 14 15, 16 , 17, 18 may depend on at least some parameters such as e.g. from the fiber composition of the mold 10, jaw pressure 21, 22, 23, 24, 25, 26, 27, 28 and also from the measurements themselves BI, Tl; B2, T2 jaws 21, 22, 23, 24, 25, 26, 27, 28 of preparation 20.
Nadalje je pri tamponu 1 po izumu med vsakokrat sosednjima žleboma (11, 12, 13,Furthermore, for the tampon 1 according to the invention, there are between each of the adjacent grooves (11, 12, 13,
14, 15, 16, 17, 18) na voljo vsakokrat po eno rebro (19), katerega zunanja površina skupaj z zunanjo površino glede na obris oz. prečni presek tampona (1) vsakokrat nasprotnega rebra (19) definira prečno dimenzijo (Al, Al) tampona 1, medtem ko dno vsakokratnega žleba (11, 12, 13, 14, 15, 16, 17, 18) definira ustrezno komprimirano jedro tampona (1) iz vpojnega vlaknastega materiala.14, 15, 16, 17, 18) each rib (19) is provided at each time, the outer surface of which together with the outer surface relative to the outline and / or outline. the cross-section of the tampon (1) of the opposite rib (19) defines the transverse dimension (Al, Al) of tampon 1, while the bottom of each groove (11, 12, 13, 14, 15, 16, 17, 18) defines the corresponding compressed core of the tampon (1) absorbent fibrous material.
Upoštevajoč dejstvo, da so omenjeni žlebovi 11, 12, 13, 14 15, 16, 17, 18 izvedeni z radialnim stiskanjem preoblikovanca 10 v tampon 1, po stiskanju prečni presek tampona 1 v tem primeru ni vsaj približno krožen, ampak je zahvaljujoč izvedbi dimenzijsko različnih žlebov 11, 12, 13, 14 15, 16, 17, 18 v obeh medsebojno zasukanih dvojicah med seboj pravokotnih ravnin obris oz. prečni presek tampona 1 temu ustrezno sploščen in spominja na kvadrat z blago zaokroženimi vogali (Sl. 1), pri čemer je omenjeni kvadrat z zaokroženimi vogali lahko definiran z debelino Al med vsakokrat nasprotnima stranicama in diagonalo A2 med vsakokrat nasprotnima zaokroženima vogalnima območjema.Taking into account the fact that said grooves 11, 12, 13, 14 15, 16, 17, 18 are made by radially compressing the form 10 into tampon 1, after compression, the cross-section of tampon 1 is not at least approximately circular in this case, but is dimensionally due to the embodiment of different grooves 11, 12, 13, 14 15, 16, 17, 18 in both mutually twisted pairs of perpendicular planes of the outline or. the cross-section of tampon 1 is accordingly flattened and resembles a square with slightly rounded corners (Fig. 1), wherein said square with rounded corners can be defined by a thickness Al between the opposite sides and a diagonal A2 between the opposite rounded corners.
Pri tamponu 1 po izumu so širine BI, B2 in globine Tl, T2 žlebov 11, 12, 13, 14In the tampon 1 according to the invention, the widths BI, B2 and the depths Tl, T2 of grooves 11, 12, 13, 14
15, 16, 17, 18 tako izbrane, da je dobljen obris oz. prečni presek tampona 1, katerega razdalja A2 v diagonalni smeri za 10 do 35% večja od debeline Al tampona 1.15, 16, 17, 18 so selected that the outline or. cross-section of tampon 1 whose distance A2 is diagonally 10 to 35% greater than the thickness of Al tampon 1.
Strokovnjakom je znano, da na trgu obstajajo različne izvedbe tamponov, ki pa so zaradi čisto fizioloških značilnosti uporabnic glede na premer in dolžino razvrščeni v tri običajne velikostne razrede. Srednja velikost tampona je znana pod nazivom »normal«, pri čemer je razred »normal« določen z območjem premerov tampona 1 in dolžin L tampona 1.It is known to experts that there are different versions of tampons on the market, but because of their purely physiological characteristics, users are classified into three common size classes in terms of diameter and length. The mean size of the tampon is known as "normal", with the class "normal" being defined by the area of diameter of tampon 1 and length L of tampon 1.
Tampon 1 po izumu je lahko tako zasnovan, da bodisi debelina Al ustreza običajni velikosti premera tamponov 1 v razredu »normal« ali pa diagonala A2 ustreza običajni velikosti premera tamponov 1. Pri tem je prva možnost prednostna in tudi lažje primerljiva s stanjem tehnike, ker je količina v njem vgrajene vpojne vlakninske snovi v takem primeru enaka ali zelo podobna količini vpojne vlakninske snovi pri običajnem cilindričnem tamponu 1 iz velikostnega razreda »normal«. Vendar pa je zaradi drugačne oblike obrisa oz. prečnega preseka tampona 1 po izumu v primerjavi s cilindričnim tamponom 1 iz stanja tehnike pri enaki količini vgrajenega vlakninskega materiala ploščina preseka večja, prav tako je večji odpomostni moment, kar ima za posledico povečanje stabilnosti, namreč upogibne oz uklonske trdnosti.The tampon 1 according to the invention can be designed in such a way that either the thickness Al corresponds to the normal size of the diameter of the tampons 1 in the "normal" class or the diagonal A2 corresponds to the normal size of the diameter of the tampons 1. In this case, the first option is preferable and also more easily comparable to the prior art because in that case, the amount of absorbent fibrous substance incorporated therein is equal to or very similar to the amount of absorbent fibrous substance in a conventional cylindrical tampon 1 of the "normal" size class. However, due to the different outline or shape. of the cross-section of the tampon 1 according to the invention, compared to the cylindrical tampon 1 of the prior art, with the same amount of embedded fibrous material, the cross-sectional area is larger, as well as the greater the torque, which results in increased stability, namely flexural or tensile strength.
Na Sl. 3 je prikazana nadaljnja različica tampona 1 po izumu, katerega vstavljalni konec 111 je zaradi lažjega vstavljanja zožen in blago zaokrožen.In FIG. 3 shows a further version of the tampon 1 according to the invention, the insertion end 111 of which is narrowed and slightly rounded for ease of insertion.
Še nadaljnja različica tampona 1 po Sl. 4 obsega odebeljen vstavljalni konec 111, zaradi katerega je tampon 1 uporabljiv kot aplikatorski tampon.A further embodiment of tampon 1 according to FIG. 4 comprises a thickened insert end 111, which makes tampon 1 usable as an applicator tampon.
Pri obeh nazadnje omenjenih različicah tamponov žlebovi 11, 12, 13, 14 15, 16, 17, 18 potekajo preko pretežnega dela dolžine L tampona 1.For the two last-mentioned versions of the tampons, the grooves 11, 12, 13, 14 15, 16, 17, 18 extend through the majority of the length L of the tampon 1.
Nadalje je tampon 1 lahko vzdolž celotne zunanje površine ali v območju vsaj dela te površine obdan z za tekočino prepustno ovojnico.Further, tampon 1 may be surrounded by a fluid-permeable envelope along the entire outer surface or in the region of at least part of that surface.
Na Sl. 5 je ponazorjen tampon 1 po izumu, katerega vstavljalni konec je omočen z enako količino tekočine kot tampon 1 iz stanja tehnike, kakršen je ponazorjen na Sl. 6. Tampon 1 po izumu se kot vsak tampon 1 med omočenjem razpre oz., nabrekne. Vendar pa pri tamponu 1 po izumu nabrekanje poteka postopoma, pri čemer se zunanja površina usloči v obliko kija. Temu nasprotno se pri primerljivem digitalnem tamponu 1 po stanju tehnike (npr. tamponu po EP 0 422 660) med omočenjem tampona enake dolžine L in enake teže vlakninskega materiala nabrekanje zunanje površine tampona vrši znatno hitreje in v obliki troblje. To ima za posledico, da je tesnilni učinek pri tamponu 1 po izumu glede tesnilni učinek tampona 1 po stanju tehnike znatno bolj izrazit, zato je tudi možnost izcejanja v tampon 1 absorbirane tekočine temu ustrezno manjša.In FIG. 5 is a depicted tampon 1 according to the invention, the insertion end of which is wetted with the same amount of fluid as the tampon 1 of the prior art as illustrated in FIG. 6. The tampon 1 of the invention, like any tampon 1, is opened or swollen during wetting. However, in tampon 1 according to the invention, the swelling is gradual, whereby the outer surface is blunted in the form of a cue. In contrast, for a comparable digital tampon 1, prior art, such as the tampon according to EP 0 422 660, swelling of the outer surface of the tampon is performed much faster and in the form of a trumpet during wetting of the same length L and the same weight of fibrous material. This results in the fact that the sealing effect of the tampon 1 according to the invention is significantly more pronounced with respect to the sealing effect of the tampon 1 according to the prior art, and therefore the possibility of leakage into the tampon 1 of the absorbed liquid is accordingly less.
