Fritstâende dispensere til tandpasta og tilsvarende materialer kendes fra de tyske patentbeskrivelser nr. 1.210.149 og 2.611.644.Freestanding dispensers for toothpaste and similar materials are known from German Patent Specifications Nos. 1,210,149 and 2,611,644.
10 Hidtil er under tryk stâende produkter blevet udleveret fra aérosol-dâser. I denne dâseart benÿttes et drivmiddel under hejt tryk til at udlevere.^produktet. En sâdan indretning kendes fra US-patentskrift nr. 3.992.003.10 So far, pressurized products have been delivered from aerosol cans. In this case, a high pressure propellant is used to deliver the product. Such a device is known from U.S. Patent No. 3,992,003.
15 Fra US-patentskrift nr. 2.356.874 kendes en dispenser med et stempel, der forskydes ved en skraldemekanisme. En glideventil skaï betjenes manuelt til enten at âbne eller lukke beholde-ren. Men det er ikke muligt at sætte beholderen under tryk med ventilen i lukket stilling.US Patent No. 2,356,874 discloses a dispenser having a piston displaced by a ratchet mechanism. A sliding valve must be operated manually to either open or close the container. But it is not possible to put the container under pressure with the valve in the closed position.

Fra US-patentskrift nr. 993.579 kendes en dispenser med et stempel, der kan forskydes ved et dertil fastgjort trækbând. Bândet er fort ud gennem et hul i beholderlèget og vikles gradvist om en drejenegle for at trekke stemplet op og derved 25 presse pasta gennem det ventilfrie skaftformede udlob. Noget af pastaen vil givet vis ogsâ trsnge gennem trækbàndshullet og snavse beholderen til. Endvidere kan trækbàndet briste, nâr pastaen bliver sej, hvilket medferer, at man ikke kan fà rest-en af pastaen ud.US Patent No. 993,579 discloses a dispenser with a piston which can be displaced by a towbar attached thereto. The tape is quickly expelled through a hole in the container bed and gradually wrapped around a swivel to pull the plunger up, thereby squeezing the paste through the valve-free shaft-shaped outlet. Some of the paste will, of course, also penetrate through the drawstring hole and dirty the container. Furthermore, the drawstring may break when the paste becomes chewy, which means that the remainder of the paste cannot be removed.

Fra US-patentskrift nr. 2.732.101 kendes en lignende dispenser for pastaagtige materialer. Dens hule ventilfrie stempelskaft er fast forbundet med stemplet og stikker ved fyldt beholder meget langt frem fra beholderlâget med fare for at knekke af, 35 hvilket medferer, at beholderen ikke kan temmes. Skraldeorgan-et til nedfering af skaft og stempel, der er formet i ét, be-From US Patent No. 2,732,101 a similar dispenser for pasty materials is known. Its hollow valve-free piston shaft is firmly connected to the piston and protrudes at the filled container very far forward from the container lid at the risk of cracking, which means that the container cannot be tamed. The ratchet means for downshifting the shaft and piston formed in one

Det er den foreliggende opfindelses formâl at anvise en frit-stâende dispenser af pumpearten, hvori der er emballeret, og hvorfra der kan udleveres under lavt tryk stâende produkter, nâr en særskilt ventil âbnes, og som automatisk lukkes.It is an object of the present invention to provide a free-standing dispenser of the pump species in which it is packaged and from which low-pressure products can be dispensed when a separate valve is opened and automatically closed.
55
Dette formâl tilgodeses ved, at den indledningsvist omtalte dispenser ifolge opfindelsen er ejendommelig ved det i den kendetegnende del af kravet anforte. Herved sikres, at dis-penseren ifolge opfindelsen tæt foran udlebet i den hule stem-10 peldrivstang har en ventil, der reagerer pà et forudindsti1let tryk, sâledes at den kun âbnes, nâr trykket pâ produktet over-stiger det tryk, hvorunder produktet oprindeligt er fyldt i beholderen. Denne trykforogelse fremkaldes ved stempelstangens nedadrettede forskydning. ..,Nâr trykket falder under det oprin-15 delige tryk, lukkes ventilen automatisk.This object is met by the fact that the initially mentioned dispenser according to the invention is peculiar to that stated in the characterizing part of the claim. This ensures that the dispenser according to the invention, close to the outlet in the hollow piston drive rod, has a valve that responds to a preset pressure so that it is opened only when the pressure on the product exceeds the pressure below which the product is originally. filled into the container. This pressure increase is caused by the downward displacement of the piston rod. .. When the pressure drops below the original pressure, the valve closes automatically.
Den foreliggende opfindelse angâr sâledes en fritstâende dispenser af pumpearten til brug for toiletprodukter, sâsom bar-bercreme, tandpasta og tilsvarende materialer, der er embal-20 leret i beholderen under lavt tryk. Produktet drives ud under yderligere tryk ved tryk pà den med tænder udstyrede stempel-drivstang, der samvirker med et pâ denne forskydeligt semi-fleksibelt stempel, der tjener til at formindske beholderens volumen, og sâledes foreger trykket pâ det allerede under tryk 25 stâende produkt. En ventil er monteret i stempelstangen til at frigore produkt gennem stempelstangens hule midte, hvilken ventil er udformet til at lukke ved det forud indstillede ud-gangstryk.The present invention thus relates to a freestanding dispenser of the pump species for use in toilet products, such as shaving cream, toothpaste and similar materials which are packaged in the container under low pressure. The product is driven out under additional pressure at the pressure of the toothed piston drive rod, which cooperates with a displaceable semi-flexible piston which serves to reduce the volume of the container, thus exerting pressure on the product already under pressure 25. A valve is mounted in the piston rod to release product through the hollow center of the piston rod, which valve is designed to close at the preset output pressure.

Pè tegningen, hvor ens henvisningstal angiver til hinanden svarende dele i de forskellige figurer, benyttes henvisnings-tallet 10 generelt til at angive en fritstâende dispenser af pumpearten og ifelge den foreliggende opfindelse. Dispenseren 5 10 omfatter en fortrinsvis cylindrisk beholder 12 med en keg- lestubformet part 14, der ender i en hais 16, hvori en stem-peldrivstang 18 er monteret tæt sluttende og forskydeligt. Stempeldrivstangen har en udlebstud 20 og er for oven udformet sâledes, at der dannes et passende fingergreb 22 for at lette 10 nedtrykning af stempeldrivstangen 18.In the drawing, where like reference numerals indicate corresponding parts in the various figures, reference numeral 10 is generally used to indicate a freestanding dispenser of the pump species and in accordance with the present invention. The dispenser 510 comprises a preferably cylindrical container 12 with a cone-shaped portion 14 ending in a hoist 16, in which a piston drive rod 18 is mounted tightly and slidably. The piston drive rod has an outlet spigot 20 and is designed above that a suitable finger grip 22 is formed to facilitate 10 depressing of the piston drive rod 18.
Fast monteret pâ stempeldrivstangen i beholderen er der en krave 26. En spiralfjeder 28 med en udgangsspænding er foran-kret til kraven 26 og til den evre del af den keglestubformede 15 part 14 ved henvisningstal let 30 for kontinuert elastisk at tvinge og trække stempeldrivstangen til en hævet stilling, efter at den er blevet trykket ned. Et trin 32 pâ stempeldrivstangen, der under tvang er fort gennem halsen 16, benyttes til at begrænse stempeldrivstangens opadrettede forskydning 20 samtidig med, at det holder stempeldrivstangen 18 i en stabil tilstand. Under kraven 26 er stempeldrivstangen udformet med savtakformede tænder 34 med nedad og udad forlobende sidefla-der 38 og afsluttet med skuldre 36. Monteret omkring stempeldrivstangen 18's tandede del er der et semifleksibelt stempel 25 40, der fungerer som et stempel, og som fortrinsvis er formet af et gummi1ignende materiale og har en fleksibel evre læbe 42 til indgreb med beholderen 12's indre vmgflade 44.Fixed to the piston drive rod in the container there is a collar 26. A coil spring 28 having an output voltage is preloaded to the collar 26 and to the even portion of the cone-shaped 15 part 14 by reference numeral 30 for continuously elasticly forcing and pulling the piston drive rod. raised position after being depressed. A step 32 of the piston drive rod, which is forcibly traversed through the throat 16, is used to limit the upward displacement 20 of the piston drive rod while keeping the piston drive rod 18 in a stable state. Under the collar 26, the piston drive rod is formed with sawtooth teeth 34 with downward and outwardly extending lateral surfaces 38 and terminated with shoulders 36. Mounted around the toothed portion of the piston drive rod 18 is a semi-flexible piston 25 which acts as a piston and is preferably formed of a rubber-like material and having a flexible outer lip 42 for engagement with the inner wall surface 44 of the container 12.
Stempeldrivstangen er hul og har ved sin nedre ende en indleb-30 sâbning 46 anbragt sâledes, at den har en lille afstand fra beholderens bund, nâr stempeldrivstangen er trykket til sin nederste stilling. I den hule stempeldrivstang er der en en-vejsventil 48, der kun âbner, nâr trykket pâ produktet over-stiger det tryk, hvorunder produktet oprindeligt er emballeret 35 i beholderen 12.The piston drive rod is hollow and has a recess 46 at its lower end so as to have a small distance from the bottom of the container when the piston drive rod is pressed to its lower position. In the hollow piston drive rod, there is a one-way valve 48 which opens only when the pressure on the product exceeds the pressure below which the product was originally packaged 35 in the container 12.
Ved betjening fâr en nedtrykning af stempeldrivstangen 18 en skulder 36 pâ en af tcnderne 34 til at gâ i indgreb med stem-When operated, a depression of the piston drive rod 18 causes a shoulder 36 on one of the teeth 34 to engage the stem.

4 plet 40 for derved at tvinge stemplet 40 nedad for yderligere sammentrykning af produktet. Stempeldrivstangens ferste for-skydning vil selvfelgelig fâ kraven 2$ til at gâ i indgreb med stemplet 40, sâledes at stemplet 40 forst trykkes ned til en 5 stilling, hvor efter hinanden felgende skuldre 36 kan gâ i indgreb med stemplet 40. Laben 42 sættes under spænding an imod beholderen 12’s sidevæg 44 og tillader stemplet 40's ned-adrettede forskydning, hvilket ogsâ tilvejebringer en tætning mod, at produktet undviger, og kraftigt modvirker stemplet 10 40's opadrettede forskydning. Stempeldrivstangen 18's nedtryk- ning fâr stemplet 40 til yderligere at forskydes nedad, hvor-ved produktet sættes under yderligere tryk og tvinger det op gennem indlebsâbningen 46. Det foregede tryk vil âbne ventilen 48 og lade produktet streipme ud af tuden 20 indtil ventilens 15 forud indstillede tryk er nâet, hvilket tryk svarer til det oprindelige emballeringstryk. Spændfjederen 28 vil derpâ trække stempeldrivstangen opad, som begrænset ved trinnet 32. Laben 42 vil imidlertid holde stemplet 40 i sin sankede stilling indtil den næste pâvirkning fra skuldrene 36 ved nedtryk-20 ning af stempeldrivstangen successivt vil forskyde pladen nedad indtil den i det væsentlige nâr beholderen 12's bund 24, ved hvilket tidspunkt i det væsentlige hele produktet vil være udleveret.4 spot 40 thereby forcing plunger 40 downward for further compression of the product. The first displacement of the plunger rod will, of course, cause the collar 2 $ to engage the plunger 40, so that the plunger 40 is first pushed down to a position where successive shoulders 36 can engage the plunger 40. The lab 42 is placed underneath. tension against the side wall 44 of the container 12 and permits the downward displacement of the plunger 40, which also provides a seal against the product avoiding, and strongly counteracts the upward displacement of the plunger 10 40. The depression of the piston drive rod 18 causes the piston 40 to be further displaced downwards, whereby the product is put under additional pressure and forces it up through the inlet opening 46. The preceding pressure will open the valve 48 and allow the product to flow out of the spout 20 until the valve 15 is pre-set. pressure is reached, which pressure corresponds to the original packaging pressure. The clamp spring 28 will then pull the piston drive rod upwards, as restricted by the step 32. However, the lab 42 will hold the piston 40 in its lowered position until the next actuation of the shoulders 36 by depressing the piston drive rod will successively displace the plate downwards until it substantially the bottom 24 of the container 12, at which time substantially all of the product will be dispensed.
25 I fig. 3 ses en andret udforelsesform for opfindelsens gen-stand, der i ait væsentligt ligner denne og fungerer pâ samme mâde som den oven for beskrevne udferelsesform for opfindel-sen. I denne udforelsesform for opfindelsen er der pâ beholderen 12's indre væg 44 udformet savtakkede tænder 60 komple-30 mentært med de savtakkede tander pâ stempeldrivstangen 18. Disse savtakkede tænder har samme retning som tanderne pâ stempeldrivstangen 18 og giver stemplet 40 en sterre stabili-tet og sikrer yderligere, at nâr stempeldrivstangen 18 gâr 35In FIG. Figure 3 shows a second embodiment of the object of the invention which is substantially similar to this one and operates in the same manner as the embodiment of the invention described above. In this embodiment of the invention, saw teeth 60 are formed on the inner wall 44 of the container 12 complementary to the saw teeth on the piston drive rod 18. These saw teeth have the same direction as the teeth on the piston driving rod 18 and give the piston 40 a sterile stability and further ensures that when the piston pin 18 goes 35
