Description

Oppfinnelsen angår en selvstengende lukkeanordning, f.eks. for flasker, tuber e.l., av den art som er angitt i hovedkravets innledning. The invention relates to a self-closing closing device, e.g. for bottles, tubes etc., of the kind specified in the introduction to the main claim.

Ved kjente pakninger av denne art er strenger av utmatet masse tilbøyelig til å henge fast til lukkeanordningen, hvilket gjør utmatingen mindre distinkt samtidig som det foreligger risi-ko for tilklining og tilstopning av blandt annet luftinntaks-kanalen. In the case of known seals of this kind, strings of discharged mass tend to stick to the closing device, which makes the discharge less distinct, while at the same time there is a risk of sticking and clogging of, among other things, the air intake channel.

Formålet med oppfinnelsen er derfor i første rekke å av-hjelpe disse ulemper og å skaffe en pakning hvor material-strengen ved utmatingen "klippes" over. Dette kan ifølge oppfinnelsen oppnås ved å utforme den selvstengende lukkeanordning i overensstemmelse med den karakteriserende del av hovedkravet. Ytterligere trekk ved oppfinnelsen fremgår av underkravene. The purpose of the invention is therefore primarily to remedy these disadvantages and to provide a seal where the material string is "cut" during the discharge. According to the invention, this can be achieved by designing the self-closing closing device in accordance with the characterizing part of the main claim. Further features of the invention appear from the subclaims.

På tegningen vises et eksempel på en utførelsesform for oppfinnelsen. Fig.l viser et lengdesnitt gjennom den øvre delen av en flaske som er fremstilt av plast,, forsynt med en lukkeanordning ifølge oppfinnelsen. Fig. 2 og 3 og 4 viser snitt etter henholdsvis linjene II-II, III-III og IV-IV i fig. 1. The drawing shows an example of an embodiment of the invention. Fig.1 shows a longitudinal section through the upper part of a bottle made of plastic, provided with a closing device according to the invention. Fig. 2 and 3 and 4 show sections along lines II-II, III-III and IV-IV respectively in fig. 1.

På tegningen betegner henvisningstallet 1 en flaske eller lignende emballasje (beholder), fremstilt av et materiale med elastisk ettergivende egenskaper, f.eks. plast med elastiske egenskaper svarende til polyeten. Derved oppnås en høy grad av deformerbarhet. Flaskens munningsparti har på tegningen form av en hals 2 som for tilkobling av et lokk, eller i dette til-felle en selvstengende lukkeanordning, har et spor 3, en gjenge e.l. In the drawing, the reference number 1 denotes a bottle or similar packaging (container), made of a material with elastic yielding properties, e.g. plastic with elastic properties similar to polyethylene. A high degree of deformability is thereby achieved. In the drawing, the mouth part of the bottle has the shape of a neck 2 which, for connecting a lid, or in this case a self-closing closing device, has a slot 3, a thread or the like.

Den nye selvstengende lukkeanordningen omfatter en første* hoveddel som er generelt betegnet med henvisningstall 4 og som her har form av en relativt stiv hylse av plast, som innvendig har en vulst 5, en gjenge e.l. for samvirke med flaskens til-svarende festedel 3 (sporet e.l.). Hylsen har i sin øvre del på tegningen redusert innerdiameter og mellom hylsens to/aksi- The new self-closing closure device comprises a first* main part which is generally denoted by reference number 4 and which here has the form of a relatively rigid sleeve made of plastic, which internally has a bead 5, a thread or the like. for cooperation with the bottle's corresponding fastening part 3 (the groove etc.). In its upper part in the drawing, the sleeve has a reduced inner diameter and between the sleeve's two/axis

Hylsens øvre del 7 på tegningen har redusert ytterdia-meter, slik at hylsen også vil ha en ringformet ytre ansats 8. c Denne øvre hylsedel har likesom flaskehalsen 2 et festeparti, f.eks. i form av en rundtgående vulst 9. Hylsen står via et an-tall ribber 10 i forbindelse med en sentral del, fra hvilken det i aksial retning utgår en tapp 11 som i sin frie ende har noe redusert diameter 12. Som det fremgår av tegningen er tap- or in the extension of successive bores, an annular inner projection 6 is consequently formed, the purpose of which will be stated later. The sleeve's upper part 7 in the drawing has a reduced outer diameter, so that the sleeve will also have a ring-shaped outer shoulder 8. c This upper sleeve part, like the bottle neck 2, has a fastening part, e.g. in the form of a circumferential bead 9. The sleeve is connected via a number of ribs 10 to a central part, from which a pin 11 emanates in the axial direction, which at its free end has a slightly reduced diameter 12. As can be seen from the drawing is loss-

Lukkeanoedningens andre hoveddel er betegnet generelt med henvisnings tal1 14 og den omfatter en hylseformet del 15 som innvendig har en festedel, f.eks. et rundtgående spor 16, som er bestemt til å samvirke med den første hoveddelens festedel 9 The second main part of the closing device is designated generally by reference number 1 14 and it comprises a sleeve-shaped part 15 which internally has a fastening part, e.g. a circumferential groove 16, which is intended to cooperate with the fastening part 9 of the first main part

From the sleeve-shaped part 15 further perpendicular to its longitudinal direction, a in relation to its length, a very thin-walled strip or young 20 which, due to its flexibility, can be

The tongue 20 has a small hole, through which the (embedded) string 13 can be passed, and by then bending or e.g. by the influence of heat to deform the string 13, a simple and effective tearable transport seal is achieved.

Lukkeanordningen omfatter også en ventilorgan i form av en ringformet del 22 hvorfra utgår en radialt innadrettet tunge 23, som hensiktsmessig avsluttes med en sirkulær plate 24. Somdet fremgår av fig. 1 er ventilorganet bestemt til åanbringes mellom flaskemunningens endedel og det første hovedelementets 4 indre ansats 6, og den ringformede delen har derved hensiktsmessig en slik tykkelse at den vil presses fast mellom disse deler. Den radialt forløpende tungen 23 vil alltid holde platen 24 rett. under den sentralt anordnede tappen 11 og i anlegg mot dennes underside, uoasett vinkelorganets vinkelstilling. The closing device also comprises a valve member in the form of an annular part 22 from which a radially inwardly directed tongue 23 emanates, which appropriately terminates with a circular plate 24. As can be seen from fig. 1, the valve member is intended to be placed between the end part of the bottle mouth and the inner shoulder 6 of the first main element 4, and the ring-shaped part thereby suitably has such a thickness that it will be pressed firmly between these parts. The radially extending tongue 23 will always keep the plate 24 straight. under the centrally arranged pin 11 and in contact with its underside, regardless of the angular position of the angle member.

Den i det foregående beskrevne lukkeanordning fungerer på følgende måte: Etter at transportsikringen er gjort uvirksom ved at tungens forbindelse med strengen 13 er bragt til opphør ved et rykk i tungen, er lukkeanordningen klar for bruk. Når man ønsker å mate ut noe av flaskens innhold, klemmer man bare lett på flasken mens man holder flasken med munningen rettet mot det sted der man ønsker utmatingen utført. Gjennom trykket på massen i flasken vil membranen 17 forskyves oppover i fig. 1 og derved føre oppad den hylseformede delen 18, slik at denne munning vil for-late tappen 11. Ved at flaskeinnholdet fritt kan.passere fra flasken inn i denne hylseformede del vil følgelig en del av dette mates ut gjennom den ringformede spalte som nå har dannet seg mellom den hylseformede delen 18 og tappen 11,12. Under denne utmating er tungen 23 med sin sentrale del 24 blitt holdt i anlegg mot tappens nedre del. Så snart trykket på flasken opphører, går membranen 17 ved sin elastisitet til sin utgangs-stilling, hvorved det påny avstedkommes tetning mellom tappen 11,12 og den hylseformede delens 18 endedel 19. Lukkeanordning-ens ulike deler går således tilbake til den i fig. 1 viste ut-gangs sti 11 ing, men innen denne stilling er nådd har ventilen 22-24 som følge av det ved nevnte tilbakegang oppstående under-trykket åpnet seg og derved tillatt innsugning av luft gjennom kanalen 25 inne i tappen 11. Så snart det er oppnådd likevekts-tilstand går også ventilen tilbake til sin stilling vist i fig. 1, i hvilken den ligger tettende an mot tappens underkant og følgelig forhindrer videre luftskiftning via kanalen 25. The previously described closing device works in the following way: After the transport safety has been rendered ineffective by the connection of the tongue with the string 13 being brought to an end by a jerk in the tongue, the closing device is ready for use. When you want to feed out some of the bottle's contents, you just squeeze the bottle lightly while holding the bottle with the mouth directed towards the place where you want the feeding to be carried out. Through the pressure on the mass in the bottle, the membrane 17 will be displaced upwards in fig. 1 and thereby lead upwards the sleeve-shaped part 18, so that this mouth will leave the pin 11. As the contents of the bottle can freely pass from the bottle into this sleeve-shaped part, a part of this will consequently be fed out through the annular slot which now has formed between the sleeve-shaped part 18 and the pin 11,12. During this discharge, the tongue 23 with its central part 24 has been kept in contact with the lower part of the pin. As soon as the pressure on the bottle ceases, the membrane 17 moves by its elasticity to its starting position, whereby a seal is again established between the pin 11,12 and the end part 19 of the sleeve-shaped part 18. The closure device's various parts thus return to the one in fig. 1 showed the output path 11 ing, but before this position has been reached, the valve 22-24 has, as a result of the negative pressure created during said decline, opened and thereby allowed the intake of air through the channel 25 inside the pin 11. As soon as the equilibrium state has been reached, the valve also returns to its position shown in fig. 1, in which it rests tightly against the lower edge of the pin and consequently prevents further air exchange via the channel 25.

Den beskrevne lukkeanordning kan på grunn av sin enkle konstruksjon masseproduseres til lav pris og den kan lett til-kobles på flasker, bokser e.l. av den innledningsvis angitte art. Ved hjelp av den hylseformede delens 18 traktform oppnås at nevnte hylseformede del utvendig holdes ren ved at rester som eventuelt hefter til lukkeorganet ved flaskens stående opp-bevaring søker seg ned i den således dannede fordypning. Det at tappen er hul medfører foruten den hovedfordel at luft kan suges inn i beholderen også at den utmatede nia t er ial s t r eng så~Due to its simple construction, the described closing device can be mass-produced at low cost and it can be easily connected to bottles, cans etc. of the initially stated species. By means of the funnel shape of the sleeve-shaped part 18, it is achieved that said sleeve-shaped part is externally kept clean by the fact that residues which may adhere to the closing member during the upright storage of the bottle find their way down into the depression thus formed. The fact that the spigot is hollow means, in addition to the main advantage that air can be sucked into the container, that the exhausted nia t is generally so tight~

Lukkeanordningen kan selvsagt være fremstilt i plast med utpregede ettergivende egenskaper, men ved å utforme membranen tilstrekkelig tynn blir det mulig å fremstille lukkeanordningen av et betraktelig stivere materiale, særlig dersom transport-sikringstungen 20 sløyfes. Når det ønskes transportsikr ing blir denne ved den viste konstruksjon' meget billig ettersom forseg-lingstrinnet kompenseres ved at strengen 13 ikke behøver skjæres av. På tegningen rager den øvre tappdelen 12 opp ovenfor den traktformede delens 19 nedre parti. I praksis ligger overgangen mellom delene 11 og 12 stort sett på samme hiva som det opptil-liggende parti av delen 19. The closing device can of course be made of plastic with pronounced yielding properties, but by designing the membrane sufficiently thin it becomes possible to make the closing device of a considerably stiffer material, especially if the transport securing tongue 20 is looped. When transport protection is desired, this becomes very cheap with the construction shown, as the sealing step is compensated by the fact that the string 13 does not need to be cut. In the drawing, the upper pin part 12 protrudes above the lower part of the funnel-shaped part 19. In practice, the transition between parts 11 and 12 is largely on the same level as the overlying part of part 19.
