Problemlosning. Problem solving.

Utmatningsanordningar for utmatning av livsmedel ur livsmedelsbehallare är allmant kanda och ett exempel pa sadana framgar av dokumentet WO 2013084203, Al. En speciell typ av utmatningsventiler av inledningsvis namnd typ och med fordelaktig funktion är kand genom dokumentet US 5 213 236. Dispensing devices for dispensing food from food containers are generally known and an example of such is shown in the document WO 2013084203, Al. A special type of discharge valves of the initially named type and with advantageous function is known from the document US 5,213,236.

Namnda typ av utmatningsventiler kan emellertid inte anvandas i samband med utmatning av produkt, fOretradesvis livsmedel, ur fOretradesvis slutna behallare till vilka det inte far strOmma in luft genom utmatningsventilerna eftersom detta skulle innebara att produktens hallbarhet i sa fall skulle fOrsamras. However, the said type of discharge valves cannot be used in connection with discharging product, preferably food, from preferably closed containers to which air must not flow in through the discharge valves as this would mean that the durability of the product would be compromised in that case.

Syftet med fOreliggande uppfinning är att med enkla medel .astadkomma att utmatningsventiler av namnd eller liknande typ kan anvandas i samband med utmatningsanordningar fOr utmatning av en produkt ur slutna behallare utan att det foreligger risk fOr att luft kan str6mma in i produkt som finns innanf6r utmatningsventilerna och i behallarna. The object of the present invention is to provide by simple means that dispensing valves of the same or similar type can be used in connection with dispensing devices for dispensing a product from closed containers without there being a risk that air can flow into product which is inside the dispensing valves and in the containers.

Fig. 1 visar ett snitt av en utmatningsventil enligt uppfinningen i snitt och i fOrstorad skala. Fig. 1 shows a section of a discharge valve according to the invention in section and on an enlarged scale.

Figur 2 visar en slitsuppvisande del av utmatningsventilen enligt figur 1. Figure 2 shows a slit-indicating part of the discharge valve according to figure 1.

Figur 3 visar utmatningsventilen enligt figur 1 anordnad pa en utmaningsanordning. 1 2 Beskrivning av en foredragen anordning enligt uppfinningen. Figure 3 shows the discharge valve according to figure 1 arranged on a challenge device. Description of a preferred device according to the invention.

Den pa ritningarna visade utmatningsventilen 1 är avsedd att medge utmatning av en produkt 2, fOretradesvis en livsmedelsprodukt, exempelvis en dryck, ur en behallare 3. Denna är fOretradesvis lufttatt tillsluten och har fOretradesvis fOrmaga att kollapsa da produkt 2 matas ut ur den samma. Utmatningen av livsmedelsprodukten 2 ur livsmedelsbehallaren 3 kan ske med hjalp av nagon typ av utmatningsanordning 4, men utmatningen kan alternativt ske genom att man klammer ihop livsmedelsbehallaren 3 med handen eller handerna eller med nagot hjalpmedel (ej visat). The discharge valve 1 shown in the drawings is intended to allow discharge of a product 2, preferably a food product, for example a beverage, from a container 3. This is preferably aerated closed and is preferably capable of collapsing when product 2 is discharged from the same. The food product 2 is discharged from the food container 3 with the aid of some type of dispensing device 4, but the discharge can alternatively be done by squeezing the food container 3 with the hand or hands or with some aid (not shown).

Utmatningsventilen 1 best& av eller uppvisar elastiskt fjadrande och aterfjadrande material och den uppvisar en ringformad ytterdel 5 och en med denna f6rbunden innerdel 6 som är utformad som ett rullmembran 7. Detta kan kan uppvisa en kalottliknande form och det buktar foretradesvis ut i en riktning mot livsmedelsproduktens 2 utmatningsriktning L. The discharge valve 1 consists of or has resiliently resilient and resilient material and it has an annular outer part 5 and an inner part 6 connected thereto which is formed as a roller diaphragm 7. This may have a cap-like shape and it preferably curves out in a direction of the food product. 2 discharge direction L.

Rullmembranet 7 uppvisar en eller flera slitsar, exempelvis fyra slitsar 8-11, som foretradesvis är anordnade i centrala delar 16 av detsamma. Nar rullmembranet 7 intar sitt ursprungslage A hailer det slitsarna 8-11 stangda och nar det bibringats ett utspant lage B medger det att slitsarna 8-11 ar Oppna for att bilda en utmatningsOppning 14 genom vilken livsmedelsprodukt 2 kan matas ut. Som framgar av figur 1 bildar rullmembranet 7 utvikta flikar 7a nar slitsarna 8-11 är 6ppna. The roller diaphragm 7 has one or more slots, for example four slots 8-11, which are preferably arranged in central parts 16 thereof. When the roller diaphragm 7 assumes its original layer A, it holds the slots 8-11 closed and when a stretched layer B is provided, it allows the slots 8-11 to be open to form a discharge opening 14 through which food product 2 can be discharged. As can be seen from Figure 1, the roller diaphragm 7 forms unfolded flaps 7a when the slots 8-11 are open.

Rullmembranets 7 ursprungslage A visas med heldragna linjer och dess utspanda lage B med streckade linjer. The original layer A of the roller membrane 7 is shown with solid lines and its expanded layer B with dashed lines.

Rullmembranet 7 kan bibringas en rullrOrelse i en Oppningsriktning X da den tryckbelastas av livsmedelsprodukt 2, som paverkar densamma da livsmedelsprodukten 2 trycks i utmatningsriktningen L. Vid denna rullrOrelse i Oppningsriktningen X trycks rullmembranet 7 fjadrande genom ytterdelen 7 och nar det uffOrt ungefar halva Oppningsrorelsen utfOr det fOretradesvis en snapprOrelse tills det intar sitt utspanda lage B. Harigenom uppnas en snabb och distinkt oppning av utmatningsventilen 1. The rolling diaphragm 7 can be imparted to a rolling movement in an opening direction X as it is pressurized by food product 2, which affects the same when the food product 2 is pressed in the discharge direction L. In this rolling movement in the opening direction X the rolling membrane 7 is resiliently pushed through Preferably a snap motion until it takes up its expanded position B. This results in a fast and distinct opening of the discharge valve 1.

Da namnda tryckbelastning pa rullmembranet 7 upphOrt genomfOr detsamma en aterrullrOrelse i en stangningsriktning Y, vid vilken den aterfjadrar genom ytterdelen 5 till sitt ursprungslage A och nar det utfOrt ungefar halva aterrullrOrelsen i stangningsrikningen Y uffOr den foretradesvis en atersnapprorelse, varigenom det uppnas en snabb och distinkt stangning av utmatningsventilen 1. When said pressure load on the roller diaphragm 7 ceases, it performs a retraction movement in a closing direction Y, at which it springs back through the outer part 5 to its original stroke A and when it has performed about half the retraction movement in the closing direction Y above, it is preferably a fast one. closing the discharge valve 1.

Som vidare framgar av figur 1 andras rullmembranets 7 lage f ran ett lage i vilket den fOretradesvis uppvisar en kalottform och skjuter ut i fOrhallande till ytterdelen 5 i en uppstroms riktning i forhallande till livsmedelsproduktens 2 utmatningsriktning L och tryckes i denna utmatningsriktning L genom ytterdelen 5 till ett lage i vilket den 3 skjuter ut i en nedstr6ms riktning i forhallande till ytterdelen 5 och vice versa. As further shown in Figure 1, the layer of the rolling membrane 7 is formed from a layer in which it preferably has a cap shape and protrudes in relation to the outer part 5 in an upstream direction relative to the discharge direction L of the food product 2 and is pressed in this discharge direction L through the outer part 5 to a layer in which it 3 projects in a downstream direction relative to the outer part 5 and vice versa.

Denna utmatningsventil 1 har en fOrdelaktig funktion, men den är inte anvandbar vid livsmedelsbehallare 3, eftersom flikarna 7a kan vika sig mat och slitsarna 8-11 kan oppna sig da den intar ursprungsform A. Detta skulle innebara att luft kan komma in till livsmedelsprodukten 2 och i livsmedelsbehallaren 3 genom utmatningsventilen 1, vilket är oacceptabelt eftersom detta skulle forsamra eller tillintetgOra livsmedelsproduktens 2 hallbarhet. This discharge valve 1 has an advantageous function, but it is not usable in food containers 3, since the flaps 7a can fold food and the slots 8-11 can open when it assumes original form A. This would mean that air can enter the food product 2 and in the food container 3 through the discharge valve 1, which is unacceptable as this would degrade or destroy the shelf life of the food product 2.

Detta problem lOses pa ett enkelt och effektivt satt med hjalp av en stoddel 15 med vilken rullmembranet 7 har stodjande kontakt da det intar sitt ursprungslage A. Harigenom fOrhindrar stoddelen 15 att slitsarna 8-11 kan 6ppna sig da rullmembranet 7 intar namnda ursprungslage A, vilket innebar att luft inte kan passera utmatningsventilen 1 in till innanfor denna befintlig livsmedelsprodukt 2 dã rullmembranet 7 intar sitt ursprungslage A. Det kan vara fOrdelaktigt att rullmembranet 7 anligger mot stOddelen 15 med tryck sa att aven minsta oppning av slitsarna 8-11 uteslutes. This problem is solved in a simple and efficient manner by means of a support part 15 with which the roller diaphragm 7 has standing contact when it assumes its original stroke A. Thereby the support member 15 prevents the slots 8-11 from opening when the roller diaphragm 7 assumes said original stroke A, which meant that air can not pass the discharge valve 1 into to inside this existing food product 2 when the roller diaphragm 7 assumes its original stroke A. It may be advantageous for the roller diaphragm 7 to abut against the support part 15 with pressure so that even the smallest opening of the slots 8-11 is excluded.

Stoddelen 15 kan vara anordnad och/eller utformad pa olika satt men likval uppvisa den efterstravade funktionen. Ett exempel pa stoddel 15 visas pa ritningarna och i detta utforande är den utformad som en rorformad del 17 genom vilken livsmedelsprodukt 2 kan matas till utmatningsventilen 1. FOr detta syfte är den rOrformade delen 17 oppen mot livsmedelsbehallaren 3 sa att livsmedelsprodukt 2 kan matas in i denna och den uppvisar sidoOppningar 18 genom vilka livsmedelsprodukt 2 kan matas till utmatningsventilen 1. The support part 15 can be arranged and / or designed in different ways but still have the desired function. An example of support part 15 is shown in the drawings and in this embodiment it is designed as a tubular part 17 through which food product 2 can be fed to the discharge valve 1. For this purpose, the tubular part 17 is open towards the food container 3 so that food product 2 can be fed into this and it has side openings 18 through which food product 2 can be fed to the discharge valve 1.

StOddelen 15 kan uppvisa en andv.agg 19 med vilken rullmembranet 7 kan samverka pa namnt satt. Vidare kan stOddelen 15 vara anordnad inuti en yttre rOrdel 20 som tillsammans med stoddelen 15 bildar ett genomstrOmningsutrymme 21 genom vilket livsmedelsprodukt 2 kan matas till utmatningsventilen1. The support part 15 can have an end wall 19 with which the roller diaphragm 7 can cooperate in a named manner. Furthermore, the support part 15 can be arranged inside an outer pipe part 20 which together with the support part 15 forms a flow space 21 through which food product 2 can be fed to the discharge valve 1.

Som namnts kan livmedelsprodukt 2 matas ut med hjalp av en utmatningsanordning 4 och en sadan kan uppvisa en slangdel 22 av elastiskt aterfjadrande material . Denna slangdel 22 kan vara anordnad inuti en rOrdel 23 med ett rOrligt utmatningsorgan 24. Slangdelen 22 är genom en kopplingsanordning 25 kopplingsbar till livsmedelsbehallaren 3 eller vice versa. Det kan finnas en backventil 26 som hindrar att livsmedelsprodukt 2, som finns i slangdelen 22, kan passera tillbaka fran denna till livsmedelsbehallaren 3. As mentioned, food product 2 can be dispensed by means of a dispensing device 4 and such can have a hose part 22 of elastically resilient material. This hose part 22 can be arranged inside a pipe part 23 with a movable discharge means 24. The hose part 22 can be coupled to the food container 3 by a coupling device 25 or vice versa. There may be a non-return valve 26 which prevents food product 2 contained in the hose part 22 from passing back therefrom to the food container 3.

FOr utmatning av livsmedelsprodukt 2 trycks utmatningsorganet 24 in, vilket innebar att slangdelen 22 trycks samman och livsmedelsprodukt 2 trycks ut ur denna i riktning L mot utmatningsventilen 1. Nar man slapper utmatningsorganet 24 kommer slangdelen 22 att aterta sin ursprungsform och darmed aterfora utmatningsorganet 24 till sitt utgangslage och samtidigt suga in livsmedelsprodukt 2 ur livsmedelsbehallaren 3 in i densamma. Darefter kan denna utmatningsprocedur upprepas. 4 Kopplingsanordningen 25 kan uppvisa en yttre, rOrformad kopplingsdel 27 och en i livsmedelsbehallaren 3 anordnad, inre kopplingsdel 28. Dessa kopplingsdelar 27,28 kan kopplas till varandra genom att man trycker hal i livsmedelsbehallaren 3 med den yttre kopplingsdelen 27 och darefter f6r in denna i den inre kopplingsdelen 28 och trycker fast kopplingsdelarna 27,28 vid varandra. Genom att den yttre kopplingsdelen 27 är rOrformad uppnas att livsmedelsprodukt 2 kan stromma fran livsmedelsbehallaren 3 genom densamma till slangdelen 22. Before discharging food product 2, the discharge means 24 is pushed in, which meant that the hose part 22 is compressed and food product 2 is pushed out of it in direction L towards the discharge valve 1. When the discharge means 24 is released, the hose part 22 returns to its original shape and thus returns the discharge means 24 to its starting layer and at the same time suck food product 2 from the food container 3 into it. This output procedure can then be repeated. The coupling device 25 can have an outer, tubular coupling part 27 and an inner coupling part 28 arranged in the food container 3. These coupling parts 27, 28 can be connected to each other by pressing hal in the food container 3 with the outer coupling part 27 and then inserting it into the food container 3. the inner coupling part 28 and presses the coupling parts 27,28 together. Because the outer coupling part 27 is tubular, it is achieved that food product 2 can flow from the food container 3 through it to the hose part 22.

UppfinnigsfOremalet är inte begransat till ovannamnda uffOranden utan det kan variera inom ramen f6r efterfoljande patentkrav. Rullmembranet 7 kan uppvisa annan form An den visade och livsmedelsbehallaren 3 kan vara en plastpase som är lufttatt tillsluten och som oppnas fOrst nar livsmedelsprodukt 2 skall matas ut ur densamma. Dessutom kan ocksa namnas att stoddelen 15 kan besta av mer an en del. Behallaren 3 kan vara en behallare fOr annan produkt an livsmedel och produkten 2 kan darmed vara vilken flytande produkt som heist vid vii ken det fOreligger krav pa hallbarhet. Behallaren behover inte heller nodvandigtvis kunna kollapsa och den behover inte nOdvandigtvis vara lufttat. The object of the invention is not limited to the above-mentioned embodiments, but it may vary within the scope of the appended claims. The roll membrane 7 may have a different shape. The shown and the food container 3 may be a plastic passage which is aerated closed and which is opened only when food product 2 is to be discharged therefrom. In addition, it can also be mentioned that the support part 15 can consist of more than one part. The container 3 can be a container for a product other than food and the product 2 can thus be any liquid product that is raised when there is a requirement for shelf life. The container also does not necessarily need to be able to collapse and it does not necessarily need to be vented.
