Description

i 147672 oi 147672 o

Opfindelsen angår en beskyttelsesmaske, som under brug danner en selvbærende lomme, og som har et efter-giveligt, deformerbart parti, der kan tilpasse sig til konturen af brugerens næseparti, og fastgørelses-5 organer, med hvilke den kan fastholdes over brugerens ansigt, samt et før brug i hovedsagen plant filtermateriale med lodret og vandret udstrækning og i midterpartiet bukket i vandret retning, så det danner en øvre og en nedre, mod hinanden vendende flade med en mellem fladerne 10 centralt placeret, vandret fold (plissé), der forkorter filtermaterialet i lodret retning.The invention relates to a protective mask which during use forms a self-supporting pocket and has a resilient, deformable portion which can conform to the contour of the user's nose portion, and fasteners with which it can be held over the user's face, and prior to use, generally flat, horizontal and horizontal filter material and in the middle portion bent in a horizontal direction to form an upper and a lower, facing surface, with a horizontal fold (pleated) centrally located between the surfaces 10 shortening the filter material in the vertical direction.

Pra PR-PS 1220851 kendes en beskyttelsesmaske, der er fremstillet af et stykke plant filtermateriale, som er ombukket langs en symmetriakse og svejst langs side-15 kanterne til dannelse af en lomme. På midten af lommens åbne kantpartier er materialet bukket ind over sig selv, så der er dannet et dobbeltlaget, tykt parti, der kan ligge tæt an mod brugerens næseparti. Sidesømmene og ombukningen ved symmetriaksen gør til en vis grad lommen 20 selvbærende, når den først er anbragt på og tilpasset brugerens ansigt, men den kan ikke opbevares i helt flad tilstand og skal i regelen pustes op eller påvirkes med træk i begge sideflader for at antage lommeform.Pra PR-PS 1220851 discloses a protective mask made of a piece of flat filter material which is folded along an axis of symmetry and welded along the side edges to form a pocket. In the middle of the open edge portions of the pocket, the material is bent over itself so that a double layered, thick portion is formed which may be adjacent to the user's nose portion. The side seams and the folding of the axis of symmetry make the pocket 20 self-supporting to some extent once placed on and aligned with the user's face, but it cannot be stored in a completely flat state and should generally be inflated or affected with features on both side surfaces to assume pocket form.

Det samme er i en vis grad tilfældet med en 25 fra US-PS 3.603.315 kendt beskyttelsesmaske, som ganske vist på indersiden er belagt med et blødt skumstoflag, som kan transportere fugtighed fra brugerens ansigt til et ydre, fugtabsorberende lag, og som tillige ved sin elasticitet skulle kunne medvirke til at lommen 30 folder sig ud, når masken tages på. Denne selvåbnende virkning er dog kun svag, og skumstoflaget bidrager kun i ringe grad til at afstive lommen under brug.The same is true to some extent with a protective mask known from US-PS 3,603,315, which is admittedly coated on the inside with a soft foam layer which can transport moisture from the user's face to an outer, moisture-absorbing layer, and also by its elasticity should be able to help the pocket 30 unfold when the mask is put on. However, this self-opening effect is only weak, and the foam layer contributes little to stiffening the pocket during use.

Det er formålet med opfindelsen at tilvejebringe en beskyttelsesmaske, som lettere end de kendte kan 35 anbringes i korrekt brugsstilling på brugerens ansigt, og som giver større sikkerhed mod at lommen suges ind mod 147672SUMMARY OF THE INVENTION It is an object of the invention to provide a protective mask which, more easily than the known ones, can be placed in the correct position of use on the user's face and which provides greater security against the pocket being sucked in against 147672

2 Lærerens næse og mund ved indånding, så filtermaterialet hurtigt bliver fugtigt.2 The teacher's nose and mouth when inhaled so that the filter material quickly becomes moist.

Dette er ifølge opfindelsen opnået ved i det mindste endnu én vandret fold i hver af de mod hinanden vendende 5 flader, hvilke folder sammen med den centralt anbragte fold afstiver den ved maskens udfoldning dannede selvbærende lomme, idet den centralt anbragte fold i vandret retning er kortere end folderne i de to mod hinanden vendende flader, hvilke folder hver for sig er kortere end filter-10 materialets største vandrette udstrækning, hvorhos de mod hinanden vendende flader i lodret retning er forbundet således med hinanden ved de yderste ender ved hver af de nævnte folder, at masken kan opbevares i sin oprindelige flade tilstand og er selvekspanderende, når den åbnes.According to the invention, this is achieved by at least one more horizontal fold in each of the opposite faces, which folds together with the centrally placed fold stiffens the self-supporting pocket formed by the unfolding of the mask, the centrally placed fold in the horizontal direction is shorter than the folds of the two facing surfaces, which folds are each shorter than the largest horizontal extent of the filter material, wherein the facing faces are vertically connected to each other at the outer ends at each of said folds that the mask can be stored in its original flat state and is self-expanding when opened.

15 Ved dette arrangement løber sidekanterne ind mod hinanden i retning bort fra maskens åbning og samvirker med de forskelligt lange folder til automatisk at danne en lomme, når brugeren af masken åbner den ved at trække åbningens to sidekanter fra hinanden, og de ulige lange 20 folder og det længere parti ved de frie kanter samvirker til at frembringe en sådan spænding i materialet, at lommen holdes i åben, afstivet tilstand.In this arrangement, the side edges run towards each other in a direction away from the opening of the mask and cooperate with the different long folds to automatically form a pocket when the user of the mask opens it by pulling the two side edges of the opening apart and the odd long folds and the longer portion at the free edges cooperate to produce such tension in the material that the pocket is kept in the open, stiffened state.

Masken ifølge opfindelsen kan let fremstilles med en passende stor og alligevel stabil lomme, og en beskyttelses-25 maske med tilfredsstillende levetid og stabilitet kan ifølge opfindelsen have et filtermateriale, som i maskens flade, ubrugte tilstand har et fladeareal på i det væsentlige 450-480 cm2.The mask of the invention can be readily manufactured with a suitably large and yet stable pocket, and a protective mask of satisfactory life and stability according to the invention may have a filter material which, in the flat, unused condition of the mask, has a surface area of substantially 450-480. cm 2.

Den åbnede maske kan let tilpasse sig til tæt anlæg 30 mod brugerens næseparti uden at genere brugeren, når en elastisk deformerbar strimmel er indlagt i filtermaterialet langs yderkanten af den ene af de modstående flader.The opened mask can easily adapt to tight abutment 30 against the user's nose portion without bothering the user when an elastically deformable strip is inserted into the filter material along the outer edge of one of the opposing surfaces.

Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, på hvilken 35 fig. 1 viser en beskyttelsesmaske ifølge opfindel sen til beskyttelse mod støv, når den bæres på ansigtet, 3 147672 o fig. 2 i skrå afbildning den i fig. 1 viste maske set nedefra og i delvis åben tilstand, hvorved maskens øvre del er delvis fjernet og delvis vist i snit, og fig. 3 i skrå afbildning masken ifølge fig. 1 i 5 dens åbne tilstand, set fra oven.The invention will now be explained in more detail with reference to the drawing, in which FIG. 1 shows a protective mask according to the invention for protection against dust when worn on the face; 2 in an oblique view, as shown in FIG. 1 is a bottom view and partially open, whereby the upper part of the mask is partially removed and partly shown in section, and FIG. 3 is an oblique view of the mask of FIG. 1 in 5 its open state, viewed from above.

På tegningen er de afbildede dele forsynet med samme henvisningstal i de enkelte figurer.In the drawing, the depicted parts are provided with the same reference numerals in the individual figures.

Ved den i fig. 1 til 3 viste udførelsesform for en maske ifølge opfindelsen er masken 10 til beskyttelse 10 mod støv fremstillet af et i hovedsagen plant filtermaterialestykke, der har en vis udstrækning i såvel lodret som vandret retning. Filtermaterialet er således bukket i det vandrette plan, at det danner mod hinanden vendende flader 14 og 16, idet en fold 18 er centralt beliggende i 15 forhold til de mod hinanden vendende flader, hvorved filtermaterialet forkortes i sin lodrette udstrækning.In the embodiment shown in FIG. 1 to 3 of a mask according to the invention, the mask 10 for protection 10 against dust is made of a generally flat filter material piece having a certain extent in both vertical and horizontal directions. The filter material is bent in the horizontal plane to form facing faces 14 and 16, a fold 18 being centrally located relative to the facing faces, thereby shortening the filter material to its vertical extent.

Hver af de mod hinanden vendende flader 14 og 16 er forsynet med i det mindste én yderligere fold 20 og 22, der yderligere forkorter filtermaterialet i dets lodrette 20 udstrækning.Each of the facing faces 14 and 16 is provided with at least one additional fold 20 and 22 which further shortens the filter material to its vertical 20 extent.

Samtlige disse folder forløber i sideretningen og er forenet med hinanden ved maskens sidekanter 24 og 26 på passende måde, f.eks. ved varmforsegling.All of these folds extend in the lateral direction and are joined to one another by the side edges 24 and 26 of the mask in a suitable manner, e.g. by heat sealing.

Folderne er anbragt på en sådan måde, at den 25 centralt beliggende fold 18 er kortere i vandret udstrækning end de yderligere folder 20 og 22, hvilke atter er kortere i vandret udstrækning end filtermaterialets største udstrækning i vandret retning. Denne placering medfører, at sidekanterne 24 og 26 løber ind mod 30 hinanden i retningen bort fra maskens åbning. Ved at anbringe folderne 18, 20 og 22 på denne måde gøres beskyttelsesmasken selvekspanderende, når den åbnes.The folds are arranged in such a way that the centrally located fold 18 is shorter in the horizontal extent than the additional folds 20 and 22, which in turn are shorter in the horizontal extent than the largest extent of the filter material in the horizontal direction. This location causes the side edges 24 and 26 to run towards each other in the direction away from the opening of the mask. By placing the folds 18, 20 and 22 in this way, the protective mask is made self-expanding when opened.

Herved behøver den person, der bærer masken, ikke at presse masken ud under dannelse af en såkaldt ånde-35 lomme, hver gang masken skal anvendes.Hereby, the person wearing the mask does not need to extrude the mask to form a so-called breath pocket each time the mask is to be used.

Filtermaterialets øvre kantområde indbefatter en sædvanlig elastisk deformerbar strimmel 28, der tjener til efter behov at forme filtermaterialets øvre kantområde efter formen af den maskebærende person 30's 5 næse. Som vist i fig. 2 og 3 er strimlen 28 fortrinsvis indlagt i filtermaterialet i en flade 14, men den kan også være anbragt uden på fladen 14. Strimlen består fortrinsvis af en trådforstærket strimmel af plastmateriale.The upper edge region of the filter material includes a conventional elastically deformable strip 28 which serves to shape the upper edge region of the filter material as needed to the shape of the nose of the mask-carrying person 30. As shown in FIG. 2 and 3, the strip 28 is preferably embedded in the filter material in a surface 14, but it may also be placed outside on the surface 14. The strip preferably consists of a wire-reinforced strip of plastic material.

Beskyttelsesmasken 10 er forsynet med fastgørelses-10 organer 32, så at den på udløselig måde kan anbringes over en maskebærende person 30's ansigt. Fortrinsvis anvendes elastiske bånd for at opnå en bekvem anbringelse af masken over personens ører.The protective mask 10 is provided with fastening means 32 so that it can be releasably placed over the face of a mask-carrying person 30. Preferably elastic bands are used to conveniently place the mask over the person's ears.

Beskyttelsesmasken 10's ydre form opnås fortrinsvis 15 ved at placere fordoblede ombukninger 34 og 36 på en sådan måde, at de forløber over de nedre henholdsvis de øvre kantområder.The outer shape of the protective mask 10 is preferably obtained by placing doubled folds 34 and 36 in such a way that they extend over the lower and upper edge regions respectively.

I fig. 3 er det tydeligt vist, hvorledes beskyttelsesmasken 10 er selvekspanderende frem mod sin åbne 20 brugsstilling derved, at et træk i maskens øvre og nedre kantområde bringer masken til at udvide sig. Når masken ikke anvendes, kan den hensigtsmæssigt opbevares i sin oprindelige, plane tilstand.In FIG. 3, it is clearly shown how the protective mask 10 is self-expanding toward its open use position in that a feature in the upper and lower edge regions of the mask causes the mask to expand. When not used, the mask may conveniently be stored in its original, flat state.

Som følge af maskens udformning er det muligt 25 at opnå en forholdsvis stor filterflade, som kan filtrere indåndingsluften, uden at personen behøver at gøre andet end at trække i de elastiske bånd og placere masken over sin mund og næse, medens masken samtidig tillige kan foldes sammen til sin forholdsvis ubetyde-30 lige størrelse, så den let kan opbevares, transporteres og håndteres.Due to the design of the mask, it is possible to obtain a relatively large filter surface which can filter the inhalation air without the person having to do anything but pull the elastic bands and place the mask over his mouth and nose, while at the same time folding the mask together to its relatively insignificant size, so that it can be easily stored, transported and handled.

Filtermaterialet har fortrinsvis en oprindelig overflade på i det væsentlige 450-480 cm , hvorved der opnås en beskyttelsesmaske med tilfredsstillende levetid, 35 og som opfylder de krav, der stilles af National Institute for Occupational Safety and Health.The filter material preferably has an original surface of substantially 450-480 cm, thereby providing a protective mask of satisfactory service life, 35 and meeting the requirements of the National Institute for Occupational Safety and Health.
