Den foreliggende opfindelse angår en doseringsretning til flydende produkter og af den i krav l's indledning angivne art, dvs. en emballage til flydende produkter, hvis rumfang skal måles, således at man bruger et passende mål af produk-5 tet, når det benyttes.The present invention relates to a dosage direction for liquid products and of the kind set forth in the preamble of claim 1, i.e. a liquid product packaging whose volume is to be measured so that a suitable measure of the product is used when used.

Til doseringsformål er det praktisk at kunne råde over en doseringsindretning, der kan sættes i halsen af den flaske, der indeholder de flydende produkter, eller endnu bedre er en i emballagen indgående del, f.eks. formet i ét med fla-10 skens hætte.For dosing purposes, it is convenient to have a dosing device which can be inserted into the neck of the bottle containing the liquid products, or even better is a part contained in the packaging, e.g. formed in one with the cap of the bottle.

Fra DK fremlæggelsesskrift 115.168 kendes således en doseringsindretning til indsætning i en flaskehals og med et målerum, der fyldes, når flasken stilles på hovedet, og et reserverum, der fyldes fra målerummet, når flasken stilles tilbage i 15 sin normale stilling, og som er i forbindelse med flaskens udløbsåbning, hvilke to rum er adskilte og har akser, der er parallelle med flaskens akse, idet målerummet har to mundinger, der er i forbindelse med flaskens indre, hvor den første munding, der benyttes ved fyldning, er i nærheden af dens udløbs-20 munding, og den anden munding er tæt ved målerummets modsatte ende for luftudstrømning under -fyldningen.Thus, from DK presentation specification 115,168 a dosing device for insertion into a bottleneck and with a measuring compartment which is filled when the bottle is turned up and a reserve space which is filled from the measuring compartment when the bottle is returned to its normal position and which is in connecting to the outlet port of the bottle, the two compartments being spaced apart and having axes parallel to the axis of the bottle, the measuring compartment having two orifices connected to the inside of the bottle, the first mouth used in filling being in proximity to its outlet 20 orifice, and the second orifice is close to the opposite end of the measuring chamber for air outflow during filling.

Når væsken når niveauet for denne anden munding, standser fyldningen bortset fra den ekstra og varierende væskemængde, såkaldt "fri væske", der fremkommer, og hvis rumfang er en 25 funktion af forskellige variable, såsom væskens specifikke vægt og flaskens fyldningsgrad. Skønt denne frie væske på grund af det deri rådende undertryk strømmer ind i flasken igen, når flasken stilles tilbage i sin normale position, giver denne doseringsanordning en mangelfuld målenøjagtighed, 30 som ikke kan anses for at være uvæsentlig.When the liquid reaches the level of this second orifice, the filling stops except for the extra and varying amount of liquid, so-called "free liquid" that emerges and whose volume is a function of various variables, such as the specific weight of the liquid and the degree of filling of the bottle. Although this free fluid, due to the negative pressure therein, flows back into the bottle when the bottle is returned to its normal position, this dosing device provides a defective measuring accuracy 30 which cannot be considered insignificant.

Doseringen afhænger i realiteten af hældningen af målerummets akse i forhold til lodret, og det er kun, når disse to akser 2The dosage actually depends on the slope of the axis of the measurement room relative to the vertical, and it is only when these two axes 2

DK 159541 BDK 159541 B

er absolut parallelle, at man får et nøjagtigt mål, idet mængden af fri væske erfaringsmæssigt varierer, når aksen ikke er lodret.are absolutely parallel to obtaining an accurate measure, since the amount of free liquid varies in experience when the axis is not vertical.

Det er den foreliggende opfindelses formål af overvinde dis-- 5 se mangler, og at anvise en doseringsindretning med en større nøjagtighed, og som også kan fremstilles på en enkel og billig måde.It is the object of the present invention to overcome these shortcomings and to provide a dosing device with greater accuracy and which can also be manufactured in a simple and inexpensive manner.

Dette formål tilgodeses ved, at den indledningsvis omtalte doseringsindretning ifølge opfindelsen er ejendommelig ved 10 det i den kendetegnende del af krav 1 anførte.This object is met by the fact that the initially mentioned dosing device according to the invention is characterized by the method of claim 1.

Et centralt kendetegn for doseringsindretningen ifølge opfindelsen er, at den består af to sprøjtestøbte elementer, der er ført sammen med snapforbindelse, og hvor det ene omfatter målerummet, fyIdeåbningen, udløbskanalen og udløbsmundingen, 15 og det andet element omfatter lagerrummet.A central feature of the metering device according to the invention is that it consists of two injection molded elements which are joined together with a snap connection, one of which comprises the measuring compartment, the feed opening, the outlet channel and the outlet mouth, and the other element comprises the storage compartment.

Udførelsesformer for opfindelsens genstand fremgår af de uselvstændige krav 2-7.Embodiments of the subject matter of the invention are set forth in the dependent claims 2-7.

Yderligere karakteristika og fordele ved opfindelsens genstand fremgår af den efterfølgende beskrivelse af nogle udførelses-20 former for opfindelsens genstand.Further characteristics and advantages of the subject matter of the invention will be apparent from the following description of some embodiments of the subject matter of the invention.

I denne forbindelse henvises der til tegningen, der kun skal opfattes som eksempelvise udførelsesformer, og hvorpå fig. la, lb og lc skematisk illustrerer en doseringsindretning ifølge opfindelsen i tre driftsstillinger, 25 fig. 2 og 3 er aksiale snit gennem to elementer, der ved deres samling udgør en praktisk udførelsesform for doseringsindretningen ifølge opfindelsen,In this connection, reference is made to the drawings, which are to be construed only as exemplary embodiments, and in which fig. 1a, 1b and 1c schematically illustrate a dosing device according to the invention in three operating positions. 2 and 3 are axial sections through two elements which, in their assembly, constitute a practical embodiment of the dosing device according to the invention,

10 På grundlag af fig. la, lb og lc beskrives princippet og betjeningen af doseringsindretningen D, som er udformet til at indsættes i halsen af en flaske F, på hvilken doseringsindretningen samtidig udgør hætten.10 Based on FIG. 1a, 1b and 1c describe the principle and operation of the dosing device D which is designed to be inserted into the neck of a bottle F, on which the dosing device simultaneously constitutes the cap.

Doseringsindretningen D har et plant låg 1, der er stift for-15 bundet med et skørt 2, hvilken enhed danner en hætte på flaskens hals. Stift forbundet med låget 1 findes‘et første rørformet element eller et rør 3, der via en skråvæg 4 er forbundet til et andet rørformet element eller rør 5 med mindre tværsnit, og som er lukket ved den modstående ende.The dispensing device D has a flat lid 1 which is rigidly connected to a skirt 2 which forms a cap on the neck of the bottle. Closely connected to the lid 1 is the first tubular element or tube 3 which is connected via a bevel wall 4 to a second tubular element or tube 5 of smaller cross-section and which is closed at the opposite end.

20 Røret 3 er delt ved en skillevæg 6, der forløber fra låget 1 til et punkt lidt inden for røret 5. Skillevæggen 6 afgrænser i røret 3 et målerum A, der er en part af dette rør og forskudt i forhold til røret 5. Røret 5 udgør et reserve-eller lagerrum B, der til den ene side er i for-25 bindelse med rummet A ved skillevæggen 6's indre ende, der sammen med væggen 4 danner en part C, der er fælles for de to rum, og til den anden side, med låget 1 gennem røret 3's anden part, er afgrænset ved skillevæggen 6, der danner en forbindelseskanal 6a. I låget 1 og lodret flugtende med 30 kanalen 6a er der en udløbsmunding 7, der kan lukkes af en klap 8.The pipe 3 is divided by a partition 6 extending from the lid 1 to a point slightly within the pipe 5. The partition 6 defines in the pipe 3 a measuring space A which is part of this pipe and displaced relative to the pipe 5. The pipe 5 constitutes a spare or storage compartment B, which on one side communicates with the compartment A at the inner end of the partition 6, which together with the wall 4 forms a part C common to the two compartments, and to it second side, with the lid 1 through the other part of the tube 3, being bounded by the partition 6 forming a connecting channel 6a. In the lid 1 and vertically flush with the duct 6a there is an outlet mouth 7 which can be closed by a flap 8.

I målerummet A's sidevæg findes en første munding 9, der sætter målerummet i forbindelse med den øvrige del af flasken F's indre. Mundingen 9 er formet i nærheden af målerummet A's forbindelse til låget 1. En anden munding 10 sætter dette 5 rum i forbindelse med den øvrige del af flaskens indre.In the side wall of the measuring room A there is a first opening 9 which connects the measuring space with the other part of the bottle F's interior. The orifice 9 is formed near the connection space of the measuring compartment A to the lid 1. Another orifice 10 connects this compartment to the other part of the interior of the bottle.

Denne munding er tilvejebragt ved enden af et rør 11, der forløber gennem skråvæggen 4 ved dennes forbindelse med røret 5, og er placeret ved niveauet for skråvæggen 4's forbindelse med røret 3. Endvidere har skillevæggen 6 en 10 munding 12 på et niveau, der er lidt nærmere ved låget 1 end mundingen 10.This orifice is provided at the end of a pipe 11 extending through the inclined wall 4 upon its connection with the pipe 5, and located at the level of the inclined wall 4's connection with the pipe 3. Furthermore, the partition 6 has a 10 orifice 12 at a level which is slightly closer to the lid 1 than the mouth 10.

Doseringsindretningen fungerer på følgende måde:The dosing device works as follows:

Med klappen 8 åben vendes flasken F i forhold til sin normale position for at nå den i fig. la illustrerede position.With the flap 8 open, the bottle F is inverted relative to its normal position to reach the one shown in FIG. 1a illustrated position.

15 Væske indeholdt i flasken F strømmer så ind i målerummet A via mundingen 9 og stiger i dette målerum samtidigt med, at atmosfærisk luft indeholdt i dette drives ud, hvilken luft via røret 11 strømmer ind i flaskens indre. Denne væskestigning fortsætter, indtil væskeniveauet når mundingen 20 10, bortset fra et lille væskeoverskud, der udgør den væske, der betegnes som fri væske.Liquid contained in the bottle F then flows into the measurement space A via the orifice 9 and rises in this measurement space at the same time as the atmospheric air contained in it is expelled, which air flows through the tube 11 into the interior of the bottle. This rise of fluid continues until the liquid level reaches the orifice 20 10, except for a small excess of liquid which constitutes the liquid referred to as free liquid.

Flasken stilles så i sin normale position (fig. Ib). Rum A's væske strømmer følgelig ind i rum B langs skillevæggen 6, idet det relative rumfang mellem rummene A og B er 25 sådan, at væskeniveauet når et punkt lidt over skråvæggen 4's forbindelse med røret 3, dvs. over mundingen 10. Det lille væskeoverskud over mundingen 10 strømmer tilbage til flasken via denne munding og røret 11, der således fungerer som et overløb. Denne returstrømning lettes af mundingen 30 12, der er formet i skillevæggen 6. Dette luftindstrømnings hul sikrer i realiteten ligevægten for nivauet i rum B og rummet A's basis op til niveauet for mundingen 10.The bottle is then placed in its normal position (Fig. 1b). Accordingly, the liquid of space A flows into space B along the partition 6, the relative volume between spaces A and B being such that the liquid level reaches a point slightly above the connection of the inclined wall 4 with the pipe 3, ie. above the mouth 10. The small excess fluid over the mouth 10 flows back into the bottle via this mouth and the tube 11, thus acting as an overflow. This return flow is facilitated by the orifice 30 12 formed in the partition 6. This air inflow hole essentially ensures the equilibrium of the level in room B and the base of the room A up to the level of the orifice 10.

Rum B's rumfang, målt op til niveauet for mundingen 10, svarer til rumfanget af den ønskede dosering, medens rum A's rumfang er lidt større, jfr. ovenfor.The volume of compartment B, measured up to the level of the mouth 10, corresponds to the volume of the desired dosage, while the volume of compartment A is slightly larger, cf. above.

For at opnå en tilstrækkelig målenøjagtighed for rumfanget af ^ den målte produktmængde, har mellemkammeret C, der forbinder rummene A og B, et minimumsrumfang. Endvidere er formen således, at væsken nemt kan strømme til rum B.In order to obtain a sufficient measuring accuracy for the volume of the measured product quantity, the intermediate chamber C connecting the compartments A and B has a minimum volume. Furthermore, the mold is such that the liquid can easily flow to room B.

Ved dette trin kan flasken igen lukkes ved hjælp af klappen 8. Denne afmålte væske, der ligger på lager i rum B, er 10 klar til brug. For at benytte væsken, vendes flasken F med halsen nedad (fig. lc). Den afmålte væskemængde lagret i rum B strømmer ud via mundingen 7. Samtidigt fyldes rum A igen, således som ovenfor beskrevet i forbindelse med fig. la.At this stage, the bottle can be closed again by means of flap 8. This metered liquid, which is stored in room B, is ready for use. To use the liquid, turn the bottle F with its neck down (Fig. 1c). The measured amount of liquid stored in compartment B flows out through the mouth 7. At the same time compartment A is filled again, as described above in connection with FIG. la.

15 Efter den første brug, hvor rum B selvfølgelig skal fyldes en første gang, kan doseringsindretningen følgelig benyttes direkte ved kun én gang at vende flasken om.Accordingly, after the first use, where compartment B is obviously to be filled for the first time, the dosing device can be used directly by inverting the bottle only once.

Doseringsindretningen, hvis princip og arbejdsmåde netop er blevet beskrevet, giver ved målingen i to trin i rummene A 20 og B en stor nøjagtighed i den dispenserede afmålte væskemængde. Endvidere kan den på en bemærkelsesværdig god måde fremstilles enkelt og billigt, f.eks. ved formning i en plast.The dosing device, the principle and working method of which has just been described, gives a high accuracy in the dispensing of the metered liquid in measuring two stages in spaces A 20 and B. Furthermore, it can be produced in a remarkably good way simply and cheaply, e.g. by molding in a plastic.

Fig. 2-9 illustrerer en sådan praktisk udførelsesform.FIG. 2-9 illustrate such a practical embodiment.

25 For at forenkle formningen fremstilles doseringsindretningen i to elementer, hvoraf det første er illustreret på fig. 2, 4 og 7, og det andet på fig. 3, 5, 6 og 8. Fig. 9 viser de to samlede parter i perspektiv.In order to simplify the molding, the dosing device is manufactured in two elements, the first of which is illustrated in FIG. 2, 4 and 7, and the second in FIG. 3, 5, 6 and 8. FIG. 9 shows the two combined parties in perspective.

Det første element er først og fremmest organet til at lukke 30 flasken F, nemlig låget 1 med skørt 2 og lukkeklap 8, der drejeligt er monteret på låget 1, og som snapper ind på en lågpart 13. Klappen 8 er udstyret med et stop 21, udformet til med prespasning at kunne sættes ind i mundingen 7 for at lukke denne.The first element is first and foremost the means for closing the bottle F, namely the lid 1 with skirt 2 and closing flap 8, pivotally mounted on the lid 1, which snaps into a lid part 13. The flap 8 is provided with a stop 21 , designed to be inserted into the orifice 7 with a press fit to close it.

Den således konstruerede lukkeindretning kan ved skørtet 2's basis omfatte en skruepart eller en snappart 14, der om nødvendigt har et orienteringshak 15, der er i indgreb med en part tilvejebragt på flaskehalsens yderside.The closure device thus constructed may comprise at the base of the skirt 2 a screw portion or a snap portion 14 which, if necessary, has an orientation notch 15 engaged with a portion provided on the outside of the bottle neck.

5 i lukkeindretningen findes fortrinsvis et indre skørt 16, der er kortere end det ydre skørt 2 og giver en tætning på den øvre part af halsens indre.5 of the closure device is preferably an inner skirt 16 which is shorter than the outer skirt 2 and provides a seal on the upper portion of the interior of the neck.

Bortset fra lukkeindretningen har det første element det cylindriske rør 3 udstyret med sin øvre munding 9 og 10 skillevæggen 6 og dets munding 12, der som illustreret i fig. 2 og i større enkelthed i fig. 7 kan være tilvejebragt i form af en spalte. Skillevæggen 6 er som vist fortrinsvis krum, for således at gøre det lettere for væsken at strømme fra rum A til rum B, medens væsken forhindres i at 15 vende tilbage ind i rum A under flaskens brugstrin.Apart from the closure device, the first element has the cylindrical tube 3 equipped with its upper orifice 9 and 10 partition 6 and its orifice 12, which as illustrated in FIG. 2 and in greater detail in FIG. 7 may be provided in the form of a slot. The partition wall 6 is, as shown, preferably curved, so as to facilitate the flow of the liquid from room A to room B, while the liquid is prevented from returning to room A during the use phase of the bottle.

Røret 3's indre ende har snaporganer 17 til samvirke med komplementære organer 17a på det andet element og et system 18 til at forhindre drejning, og som også samvirker med et komplementært system 18a på det andet element.The inner end of the tube 3 has snap means 17 for cooperating with complementary means 17a on the second element and a system 18 for preventing rotation, which also cooperates with a complementary system 18a on the second element.

20 Det andet element er formet af røret 5, skråvæggen 4 og røret 11 med mundingen 10, idet denne helhed er formet i ét.The second element is formed by the pipe 5, the inclined wall 4 and the pipe 11 with the orifice 10, the whole being formed in one.

Som det fremgår af fig. 5 og 8, er røret 5 lukket ved sin basis, er halvcylindrisk og har en første cylindrisk vægpart 25 19 tilpasset til at forløbe i forlængelse af røret 3's cy lindriske væg, og en anden vægpart 20, der støder til røret 11 og er plant eller fortrinsvis, som vist, udad konvekst krummet for at forøge tværsnittet af kanalen fra rum A til rum B mellem denne væg 20 og skillevæggen 6.As shown in FIG. 5 and 8, the tube 5 is closed at its base, is semi-cylindrical and has a first cylindrical wall portion 25 19 adapted to extend beyond the cylindrical wall of the tube 3, and a second wall portion 20 adjacent to the tube 11 and is flat or preferably, as shown, outwardly convexly curved to increase the cross-section of the channel from compartment A to compartment B between this wall 20 and the partition 6.
