Opfindelsen angår en beskyttelseshætte til beholderudtømningsventiler, navnlig anstikkerventiler på fadølfustager, og omfattende en topplade og et dermed sammenhængende skørt med indadfjedrende, fortrinsvis 5 par- eller gruppevis i omkredsretningen arrangerede spærreflige til ved anlæg mod undersiden af en krave på udtømningsventilen at hindre aftagning af hætten uden synlig beskadigelse af denne.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective cap for container discharge valves, in particular liner valves on draft beer racks, and comprising a top plate and an associated skirt with inwardly sprung, preferably 5 pairs or groups in circumferential direction, for locking flaps for contacting the underside of the exhaust vent collar. visible damage to this one.

Sådanne beskyttelseshætter, der primært tjener 10 til garantilukning af fadølfustager er kendt fra DE-A-34 17812 og DK-B-158083, hvoraf sidstnævnte beskriver en for sprøjtestøbning særlig fremstillingsvenlig udførelse, der tillige i sin brugsstilling tilvej ebringer en tilfredsstillende vand- og støvtætning.Such protective caps, which primarily serve to guarantee the closure of draft beer racks, are known from DE-A-34 17812 and DK-B-158083, the latter of which discloses a particularly manufacturing-friendly design for injection molding, which also provides a satisfactory water and dust seal. .

15 Ved de nævnte kendte udførelser forløber spærre fligene skråt opefter fra skørtets inderside under en vinkel med skørtet som i ubelastet tilstand er omkring 45°.In the known prior art embodiments, the tabs extend obliquely upwardly from the inside of the skirt at an angle to the skirt which in the unstressed state is about 45 °.

Denne udformning af spærrefligene beror på den 20 forudsætning, at ventilkraven på visse standardudførelser af fadølfustager har en skråt indad og nedefter rettet underside, således at spærrefligen fra den med skørtets inderside hovedsageligt parallelle stilling som den indtager, når hætten under påsætningen 25 presses ned over kraven, uhindret kan svinge indefter til sin brugsstilling samtidigt med at fligens indad-rettede overkant stadig kommer i anlæg mod kravens underside, så hætten i hovedsagen er fastholdt i aksial retning. Som en yderligere forudsætning for spærrefli-30 gens korrekte funktion må der under ventilkraven være tilstrækkelig plads til spærrefligens indsvingning.This design of the latches is based on the premise that the valve collar on certain standard versions of draft beer holders has an inclined inward and downwardly directed underside, such that the latching tab from the substantially parallel position of the skirt as it occupies when the cap under the cover 25 is pressed down over the collar , can freely swing inward to its position of use while at the same time the inwardly directed upper edge of the tab still abuts against the underside of the collar, so that the cap is generally held in the axial direction. As a further prerequisite for the proper functioning of the ratchet 30, there must be sufficient space under the valve collar for the swing of the ratchet.

Disse forudsætninger er imidlertid ikke altid opfyldt, idet der på markedet, i nogle lande endda med betydelig udbredelse, forekommer fadølfustager med en 35 forholdsvis tynd ventilkrave med plan underside, og hvor ventilkravens omkreds tilmed ikke altid er fuldt DK 168887 B1 2 cirkulær, men udviser retliniede kordeafsnit. Yderligere har disse fustager under ventilkraven og i kort afstand fra dennes underside ofte en rundtgående vulst, således at der til optagelse af spærrefligene kun fin-5 des en forholdsvis snæver indskæring mellem ventilkraven og denne vulst, hvilket i praksis forhindrer spærrefligene i de kendte hætter i at kunne svinges tilstrækkeligt indefter til indtagelse af den tilsigtede brugsstilling.However, these assumptions are not always met, as in the market, in some countries even with widespread use, there are draft beer holders with a 35 relatively thin valve collar with a flat underside, and where the circumference of the valve requirements is not always fully circular, but exhibits rectilinear chord sections. Further, these footsteps below the valve collar and, at a short distance from its underside, often have a circumferential bead, so that for accommodating the locking tabs there is only a relatively narrow cut between the valve collar and this bead, which in practice prevents the locking tabs in the known caps in to be swiveled sufficiently inward to take the intended position of use.

10 Ved opfindelsen tilsigtes det at frembringe en navnlig for sidstnævnte type af fadølfustager egnet beskyttelseshætte, hvor disse ulemper, som i praksis fører til at de kendte beskyttelseshætter ikke kan monteres tilfredsstillende, er undgået.It is an object of the invention to provide a protective cap particularly suitable for the latter type of draft beer holder, which avoids these disadvantages, which in practice cause the known protective caps to be unsatisfactory.

15 Dette opnås ifølge opfindelsen ved, at spærre fligene hovedsageligt er plane og omtrent vinkelrette på toppladen, medens de i et med toppladen parallelt plan rager skråt indefter fra skørtets inderside, hvorhos hver spærrefligs overkant er i det væsentlige pa-20 rallel med toppladen i en til nævnte kraves tykkelse passende afstand fra denne, medens underkanten forløber skråt opefter fra skørtets inderside, således at den aksiale udstrækning af spærrefligens indadvendende kant er væsentligt mindre end den aksiale udstrækning 25 ved skørtets inderside.This is achieved according to the invention in that the tabs are substantially planar and approximately perpendicular to the top plate, while projecting in a plane parallel to the top plate from the inside of the skirt, the upper edge of each barrier tab being substantially parallel to the top plate in a to the thickness of said collar a suitable distance from it, while the lower edge extends obliquely upwards from the inside of the skirt, so that the axial extent of the inward edge of the ratchet is substantially smaller than the axial extent 25 at the inside of the skirt.

På grund af spærrefligens med toppladen parallelle overkant kan beskyttelseshætten ifølge opfindelsen tilpasses til fastgørelse på ventilkraver med plan underside uden mulighed for aksial forskydning 30 efter anbringelsen, og den forholdsvis korte aksiale udstrækning af spærrefligenes inderkanter medfører at fligene kan optages selv i et forholdsvis snævert mellemrum mellem kraven og en underliggende vulst.Due to the barrier top parallel to the top plate parallel, the protective cap of the invention can be adapted for attachment to flat collar valve collars without the possibility of axial displacement 30 after the application, and the relatively short axial extension of the inner edges of the latch tabs allows the tabs to be accommodated even in a relatively narrow space between the collar and an underlying bead.

Den skrå afskæring af spærrefligens underkant 35 medfører at påsætningen i det væsentlige foregår lige så nemt som ved de kendte hætter. En yderligere påsæt- DK 168887 B1 3 ningsvenlig udførelse kan opnås ved, at hver spærrefligs underkant har et i det væsentlige konkavt buet eller af retliniede afsnit sammensat forløb.The oblique cut of the lower edge 35 of the latch means that the application is substantially as easy as with the known caps. A further application-friendly design can be achieved in that the lower edge of each locking tab has a substantially concave curved or rectilinear section.

Ved en udførelse, hvor spærrefligene er anbragt 5 parvis på en sådan måde, at de to spærreflige i hvert par konvergerer mod hinanden, kan der yderligere opnås en forbedret sikkerhed mod drejning af hætten i forhold til ventilkraven, således at der opnås en forbedret sikkerhed mod ikke-beskadigende fjernelse af hætten 10 også fra ventilkraver, der ved omkredsen som nævnt ovenfor har et eller flere retliniede kordeafsnit, hvor de tilstedeværende spærreflige ikke griber ind under ventilkraven.In an embodiment in which the locking tabs are arranged in pairs in such a way that the two locking tabs in each pair converge towards each other, an improved safety against turning the cap relative to the valve collar can be further obtained, so that an improved safety against non-damaging removal of the cap 10 also from valve collars having, at the circumference, as mentioned above, one or more rectilinear chord sections where the interlocking tabs present do not interfere with the valve collar.

På samme måde som det i og for sig er kendt fra 15 ovennævnte DK-B-158083 kan en for sprøjtestøbning særlig velegnet og fremstillingsvenlig udførelse, hvorved hætten i en operation kan fremstilles i sin endelige facon opnås ved, at toppladen i aksial flugt med hver af spærrefligene har en i toppladens kant udmundende 20 indskæring ved hvis inderkant toppladen gennem et bøje-hængsel er sammensat med en tætningsflig, der før påsætningen er rettet nedad mod den tilhørende spærre-flig, men ved hættens påsætning tvinges opad af ventilkraven mod en stilling, i hvilken den udfylder indskæ-25 ringen.As is known per se from the above-mentioned DK-B-158083, a particularly suitable and manufacturing-friendly design for injection molding, whereby the cap in an operation can be manufactured in its final shape is obtained by the top plate in axial flight with each of the locking tabs, a cutout 20 opening at the edge of the top plate has an inner edge of which the top plate through a bend hinge is composed of a sealing tab which is directed downwards towards the associated locking tab, but is forced upwards by the valve collar to a position, in which it fills the notch.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, hvor fig. 1 viser en del af en foretrukket udførelsesform for beskyttelseshætten ifølge opfindelsen set 30 ovenfra inden påsætningen, fig. 2 et forstørret udsnit af fig. 1, fig. 3 et akseparallelt snitbillede efter linien III-III i fig. 2, fig. 4 et plant billede af en spærreflig, 35 fig. 5 et aksialt snitbillede af beskyttelses hætten anbragt på en fadølfustage med ventilkrave med plan underside, og DK 168887 B1 4 fig. 6 et ovenfra set billede af ventilkraven i fig. 5.The invention will now be explained in more detail with reference to the drawing, in which 1 is a top view of part of a preferred embodiment of the protective cap according to the invention prior to application; FIG. 2 is an enlarged sectional view of FIG. 1, FIG. 3 is a sectional sectional view taken along line III-III of FIG. 2, FIG. 4 is a plan view of a barrier tab; FIG. 5 shows an axial sectional view of the protective cap mounted on a draft beer canopy with a flat collar valve collar, and DK 168887 B1 4 fig. 6 is a top plan view of the valve collar of FIG. 5th

Fig. 1 viser den ene halvdel af toppladen 1 ved en foretrukket udførelsesform for beskyttelseshætten i-følge opfindelsen. I den viste udførelse er der langs toppladen l's omkreds udformet et antal med lige store vinkelintervaller, f.eks. 22,5°, placerede indskæringer 2, som ligger i aksial flugt med hver sin skråtstillede indadrettede spærreflig 3.FIG. 1 shows one half of the top plate 1 in a preferred embodiment of the protective cap according to the invention. In the embodiment shown, a number of equal angular intervals are formed along the circumference of the top plate 1, e.g. 22.5 °, located notches 2 which are in axial flight with each inclined inwardly locking tab 3.

Spærrefligene 3 er hovedsageligt plane og omtrent vinkelrette på toppladen 1. I et med toppladen 1 parallelt radialplan forløber spærrefligene skråt indefter fra indersiden af det med toppladen 1 sammenhængende skørt 4 under en vinkel på f.eks. 55-60° med en radius midt på fligen.The latches 3 are substantially planar and approximately perpendicular to the top plate 1. In a radial plane parallel to the top plate 1, the latches extend inwardly from the inside of the skirt 4 connected to the top plate 1 at an angle of e.g. 55-60 ° with a radius in the middle of the tab.

Til anlæg mod en plan underside af en ventilkrave er overkanten 5 af spærrefligene 3 i det væsentlige parallel med toppladen 1, medens underkanten 6 af hensyn til hættens nedpresning over kraven under påsætning forløber skråt opefter fra skørtets inderside. Hermed bliver den aksiale udstrækning af fligen ved dens inderkant 7 væsentligt mindre end den aksiale udstrækning ved skørtets inderside, f.eks. mindre end halvdelen af denne.For abutment against a flat underside of a valve collar, the top edge 5 of the latching tabs 3 is substantially parallel to the top plate 1, while the bottom edge 6, due to the cap's compression over the collar during application, extends upwardly from the inside of the skirt. Hereby, the axial extension of the tab at its inner edge 7 becomes substantially smaller than the axial extension at the inside of the skirt, e.g. less than half of this.

En optimal påsætningsvenlighed opnås som følge af, at underkanten 6 udviser et i det væsentlige konkavt forløb, f.eks. som vist i fig. 4 med to retliniede afsnit 6a og 6b, hvoraf det nærmest skørtets inderside liggende afsnit 6a forløber mere stejlt opefter end det mod inderkanten 7 rettede afsnit 6b. Denne udformning giver god sikkerhed mod ødelæggelse af fligen selv ved forholdsvis kraftig nedpresning over en ventilkrave.An optimum applicability is achieved as a result of the lower edge 6 exhibiting a substantially concave course, e.g. as shown in FIG. 4 with two rectilinear sections 6a and 6b, the portion 6a closest to the inside of the skirt extending more steeply upward than the section 6b directed towards the inner edge 7. This design provides good security against the destruction of the tab even by relatively heavy compression over a valve collar.

Udformningen af toppladen 1 med de i aksial flugt med fligene 3 liggende udskæringer 2 sikrer at hætten kan fremstilles i sin endelige facon ved DK 168887 B1 5 sprøjtestøbning i en forholdsvis enkel form bestående af to parter. Ved inderkanten af hver udsparing af toppladen 1 gennem et bøjehængsel 8 sammensat med en i den ubelastede tilstand nedragende tætningsflig 9, 5 som imidlertid ved hættens påsætning på en ventilkrave tvinges opefter til den i fig. 5 viste stilling.The design of the top plate 1 with the cut-outs 2 in the axial flight with the tabs 3 ensures that the cap can be manufactured in its final shape by injection molding in a relatively simple two-part mold. At the inner edge of each recess of the top plate 1 through a bending hinge 8 composed of a sealing tab 9, 5 which extends in the unloaded state, which, however, is forced upwards by the cap on the valve collar to the one shown in FIG. 5.

Snitbilledet i fig. 5 illustrerer hættens anbringelse på en fustageventilkrave 10 af den type der har forholdsvis ringe tykkelse og plan underside, og 10 hvor der tillige på ventilstudsen 11 i kort afstand under kraven 10 findes en rundtgående vulst 12, så der kun er en forholdsvis snæver indskæring til optagelse af spærrefligene 3.The sectional view of FIG. 5 illustrates the cap's position on a fustage valve collar 10 of the type having a relatively small thickness and plane underside, and 10 wherein also a short bore 12 is provided on the valve stem 11 for a short distance below the collar 10, so that there is only a relatively narrow cut to accommodate. of the latches 3.

Ventilkraver af den omhandlede type er som vist 15 i fig. 6 ikke altid cirkulære, men kan have et eller flere retliniede kordeafsnit 14.Valve collars of the type in question are as shown in FIG. 6 may not always be circular, but may have one or more rectilinear chord sections 14.

For at give en yderligere sikkerhed mod frigørelse af fligene 3 ved et sådant kordeafsnit, er fligene i forbindelse med den i fig. 1 viste parvise 20 anbringelse udformet således, at de to flige i hvert par konvergerer mod hinanden. Når beskyttelseshætten i-øvrigt størrelsesmæssigt er tilpasset den ventilkrave den skal anbringes på, opnås herved en god sikkerhed mod drejning af hætten i forhold til ventilkraven og 25 dermed mod ikke beskadigende fjernelse af hætten.In order to provide additional security against release of the tabs 3 at such a chord section, the tabs in connection with the one shown in FIG. 1, pairwise arrangement 20 is arranged so that the two tabs in each pair converge towards each other. Moreover, when the protective cap is adapted in size to the valve collar to which it is to be placed, a good safety is obtained against turning the cap relative to the valve collar and thus against non-damaging removal of the cap.
