Opfindelsen angår en beholder med tilhørende hætte og af den art, som har et udledningsrør, som er åbent i den ende, der er længst borte fra beholderen, og hvor beholderindholdet kan udledes i røret gennem en måleåbning længst borte fra 5 den åbne ende af dette rør, og hvor hætten har en tap, som, når hætten er i sin lukkede stilling i forhold til beholderen, er indført i røret for at forhindre materialeudledning gennem dette, men uden at berøre måleåbningen.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a container with an associated cap and of the kind having a discharge tube which is open at the end furthest away from the container and wherein the container contents can be discharged into the tube through a measuring opening farthest away from the open end thereof tube, and wherein the cap has a pin which, when the cap is in its closed position relative to the container, is inserted into the tube to prevent material discharge through it, but without touching the metering opening.

10 Beholdere til flydende materialer, såsom væsker, pastaer, geleer og pulvere, og som er beregnet til at kunne udlede disse materialer gennem en måleåbning med henblik på at give en kontrolleret udledning af beholderindholdet er velkendte.Liquid material containers, such as liquids, pastes, gels and powders, which are intended to discharge these materials through a measuring aperture to provide a controlled discharge of the container contents are well known.

15 Det er også kendt at forsyne en sådan beholder med en hætte, der har en tap, som kan gribe ind i måleåbningen og lukke beholderen, når hætten er i sin lukkede stilling.It is also known to provide such a container with a cap having a pin which can engage the metering opening and close the container when the cap is in its closed position.

En alvorlig ulempe ved sådanne kendte beholdere med hætter 20 er imidlertid, at slid mellem tappen og måleåbningen efter et vist antal hættelukninger forstørrer måleåbningen, hvorefter åbningen ikke længere giver den ønskede kontrollerede udledning, og at en sådan forstørrelse af åbningen ved slid mod tappen gør lukningen mangelfuld.However, a serious disadvantage of such known containers with caps 20 is that wear between the pin and the measuring opening enlarges the measuring opening after a certain number of cap closures, after which the opening no longer provides the desired controlled discharge and such an enlargement of the opening by wearing the pin makes the closure deficient.

For at overvinde dette problem foreslås i det schweiziske patent nr. 426.565 en beholderform, hvor måleåbningen udmunder i et konisk kammer, der tiltager i tværsnitsareal hen imod den ende, der er længst borte fra måleåbningen, og hætten har en konisk tap med en konicitet, der er identisk med det koniske kammers konicitet. Med lukket hætte er den koniske tap indført i det koniske kammer for at hindre materialeudstrømning fra kammeret og dermed fra måleåbningen, uden at tappen berører måleåbningen.To overcome this problem, Swiss Patent No. 426,565 proposes a container form in which the measuring aperture opens into a conical chamber which increases in cross-sectional area towards the end furthest from the measuring aperture, and the cap has a conical tap with a conicity, which is identical to the conical chamber conicity. With a closed cap, the tapered pin is inserted into the tapered chamber to prevent material outflow from the chamber and hence from the measuring opening, without the pin touching the measuring opening.

Denne beholder med hætte lider af en medfødt fejl derved, at beholderindholdet kan blive fanget i en fælde mellem den koniske side af tappen og den koniske væg i kammeret, når 35 2 150455 O'.This cap container suffers from a congenital defect in that the container contents may be trapped in a trap between the tapered side of the pin and the tapered wall of the chamber when reached.

den koniske tap føres ind i det koniske kammer for at frembringe en lukning, og medens tappen føres indad i kammeret, bliver flugtvejen for et sådant fanget materiale stadig forlæn-5 get og indsnævret i tværsnittet. Selv om nogle lavviskose væsker kan undslippe og tillade fuldstændig lukning uden overdrevent aksialt tryk på samlingen, kan sådanne fuldstændige lukninger ikke opnås med væsker med højere viskositet eller med faste materialer i pulver- eller granulatform.the tapered pin is inserted into the tapered chamber to produce a closure, and as the pin is inserted inwardly of the chamber, the escape path of such trapped material is still extended and narrowed in the cross section. Although some low viscous fluids may escape and allow complete closure without excessive axial pressure on the joint, such complete closures cannot be obtained with higher viscosity fluids or with solid or powdered materials.

Formålet med opfindelsen er at anvise et enkelt udformet beholderlukke, hvor lukning af beholderens måleåbning kan foretages over for de fleste materialer, der flyder ved lavt tryk, uden urimelige belastninger på lukketøjet og uden fare for, 15 at beholderindholdet bliver fanget på uheldig måde mellem lukkefladerne i samlingen.The object of the invention is to provide a single shaped container closure in which closure of the measuring opening of the container can be made against most materials which flow at low pressure, without undue strain on the closure and without risk of the container contents being trapped in an uncomfortable manner between the closure surfaces. in the collection.

Beholderen ifølge opfindelsen er ejendommelig ved, at røret er cylinderformet, og at tappen er cylinderformet og har en 20 sådan ydre diameter, at den på en stempelagtig måde kan føres ind i den åbne ende af røret, og bringes til at glide i dette rør.The container according to the invention is characterized in that the tube is cylindrical and that the pin is cylindrical and has an outer diameter such that it can be inserted into the open end of the tube in a piston-like manner and caused to slide in this tube.

Hermed opnås, at lukningen foretages ved, at den cylindriske 25 tap glider stempelagtigt ind i det cylindriske rør, så at beholderindholdet i røret bliver skubbet foran tappen og, når der er for meget af det, tilbage gennem måleåbningen til beholderen uden fare for, at beholderindholdet bliver fanget på uheldig måde mellem lukkefladerne i røret, og uden at 30 lukketøjet belastes unødigt.This results in the closure being effected by the cylindrical tab sliding piston-like into the cylindrical tube so that the container contents of the tube are pushed in front of the pin and, when there is too much of it, back through the measuring opening to the container without the danger of the container contents are trapped in an unfortunate manner between the closure surfaces of the tube and without unnecessarily straining the closure.

En særlig hensigtsmæssig udførelsesform, der tillige er enkel at fremstille, kan ifølge opfindelsen opnås ved, at røret er koncentrisk med hovedaksen af beholderen, hvorved der til-35 lige sikres optimale udstrømningsforhold, hvilket især har betydning i forbindelse med pulver- eller granulatformede beholderindhold.A particularly convenient embodiment, which is also simple to manufacture, according to the invention can be obtained by the tube being concentric with the main axis of the container, thereby also ensuring optimum flow conditions, which is particularly important in connection with powder or granular container contents.

Ved en foretrukken udførelsesform ifølge opfindelsen befinder tappen sig et stykke fra måleåbningen, når hætten er i sin lukkede stilling, hvorved man undgår, at tappen beskadiger måleåbningen.In a preferred embodiment of the invention, the pin is located a distance from the measuring aperture when the cap is in its closed position, thereby preventing the pin from damaging the measuring aperture.

5 Når ifølge opfindelsen røret er udformet i en prop, som er optaget i en hals i beholderen, opnås, at røret kan fremstilles særskilt uafhængigt af fremstillingen af beholderen, og at opfindelsen kan anvendes i forbindelse med en beholder med almindelig hals.When according to the invention the tube is formed in a plug which is received in a neck in the container, it is obtained that the tube can be manufactured separately independently of the manufacture of the container and that the invention can be used in connection with a container with ordinary neck.

10 Ved en ligeledes foretrukken udførelsesform har tappen en sådan længde, at hætten ved begyndende indgreb med beholderen lader tappen være fri af røret. Herved sikres det, at tappens placering i forhold til røret er fastlagt korrekt, inden tappen ved hættens fortsatte nedføring over halsen møder røret og 15 indføres i dette, hvilket sikrer en problemfri indføring af tappen i røret, og mindst mulige beskadigelser af disse.In a similarly preferred embodiment, the cap is of such a length that the cap, upon initial engagement with the container, leaves the cap free of the tube. This ensures that the position of the pin relative to the tube is correctly determined before the pin, when the cap is continued down over the neck, meets the tube and is inserted into it, which ensures a trouble-free insertion of the pin into the tube, and the least possible damage thereof.

Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor 20 fig. 1 viser et aksialsnit gennem en hætte ifølge opfindelsen og fig. 2 et aksialsnit gennem en beholderhalsdel, hvor der er vist alternative rørarrangementer til udledning af beholderindholdet.The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 shows an axial section through a hood according to the invention and FIG. 2 is an axial section through a container neck portion showing alternative pipe arrangements for discharging the container contents.

25 Figurerne viser med fuldt optrukne streger en første udførelsesform for et lukkearrangement til en beholder C og med stiplede linier et andet lukkearrangement til samme beholder.The figures show, with fully drawn lines, a first embodiment of a closure arrangement for a container C and in dashed lines a second closure arrangement for the same container.

Med reference til den første udførelsesform omfatter lukkearrangementet for beholderen C en hætte 1 og en prop 2, der 30 er presset ned i halsen 3 på beholderen C. Hætten 1 og proppen 2 kan passende være udført i halvstift plastmateriale ved støbeprocesser.With reference to the first embodiment, the closure arrangement of the container C comprises a cap 1 and a plug 2 pressed down into the neck 3 of the container C. The cap 1 and the plug 2 may suitably be made of semi-rigid plastic material by molding processes.

Halsen 3 har et ydre gevind 4, der kan samvirke med et indre gevind 5 i hætten 1.The neck 3 has an outer thread 4 which can cooperate with an inner thread 5 in the cap 1.

Proppen 2 kan passende indeholde en påføringsanordning vist som et bundt fibre 6, der omringer udløbsåbningen på behol-5 deren C.Suitably, the plug 2 may contain an application device shown as a bundle of fibers 6 surrounding the outlet opening of the container C.

Proppen 2 indeholder en måleåbning 7, der er i åben forbindelse med det indre af beholderen C, og som munder ud i et cylindrisk rør 8 med større tværsnitsareal end i måleåbningen 7. Beholderen C, proppen 2 og hætten I er i lukket tilstand, 10 når der bortses fra gevindene 4 og 5 og fiberbundterne 6, koncentriske omkring en akse A-A, så at måleåbningen og røret 8 er koaksiale som vist. Den frie ende af røret 8 (fjernest fra måleåbningen 7) har en skrå kant 9 og udmunder ved en ydre anlægsflade 10 på proppen 2. Måleåbningen 7 og/eller 15 røret 8 kan være tildannet i proppen 2 ved støbning eller senere .The plug 2 contains a measuring aperture 7 which is openly connected to the interior of the container C, which opens into a cylindrical tube 8 with a larger cross-sectional area than in the measuring aperture 7. The container C, the plug 2 and the cap I are in the closed state. except for the threads 4 and 5 and the fiber bundles 6, concentric about an axis AA so that the measuring aperture and the tube 8 are coaxial as shown. The free end of the tube 8 (farthest from the measuring opening 7) has an inclined edge 9 and opens at an outer abutment surface 10 on the plug 2. The measuring opening 7 and / or 15 the tube 8 may be formed in the plug 2 by molding or later.

Hætten 1 har en aksialt orienteret, tap 12 med en sådan diameter, at den kan glide ind i røret 8 med minimal frigang, og den frie ende af tappen 12 er fortrinsvis halgkugleformet 20 som vist med henblik på at lette indføring af den i røret 8.The cap 1 has an axially oriented pin 12 with a diameter such that it can slide into the tube 8 with minimal clearance, and the free end of the pin 12 is preferably hemispherical 20 as shown to facilitate insertion of it into the tube 8. .

Hætten 1 har endvidere en indre skulder 13, der er bestemt til at fastlægge en ringformet støtteoverflade, der, når den ligger an mod anlægsfladen 10 på proppen 2, begrænser den aksiale fremføring af hætten 1 på halsen 3. Skulderen 13 lig-25 ger i et plan P vinkelret på aksen A-A og den frie ende af tappen 12 rager igennem planet P med en aksial længde L, som . er en lille smule mindre end den aksiale længde h af røret 8.The cap 1 further has an inner shoulder 13 which is intended to establish an annular support surface which, when abutting the abutment surface 10 of the plug 2, restricts the axial advance of the cap 1 on the neck 3. The shoulder 13 lies in a plane P perpendicular to the axis AA and the free end of the pin 12 projecting through the plane P with an axial length L, which. is slightly smaller than the axial length h of the tube 8.

. I praksis udledes beholderindholdet ved, at man tager hætten 30 1 af og hælder eller bøjer beholderen for at få beholderind holdet til at løbe ud gennem måleåbningen 7 og røret 8, hvorfra beholderindholdet kan spredes eller smøres ud af fibrene 6.. In practice, the container contents are discharged by removing the cap 30 1 and tilting or bending the container to cause the container contents to extend through the measuring aperture 7 and the tube 8, from which the container contents can be spread or lubricated from the fibers 6.

Ved lukning af beholderen bliver hætten 1 anbragt på halsen 3 og gevindene 4 og 5 bragt i indgreb med hinanden, og ved drejning af hætten 1 i forhold til beholderen C føres hætten aksialt ned over halsen 3. Med gevindene 4 og 5 i begyndende 5 indgreb med hinanden er tappen 12 i hætten placeret til ak-sial indføring i røret 8, og når den aksiale nedføring af hætten 1 over halsen 3 skrider frem, indføres tappen 12 i røret 8 og fremføres aksialt inden i dette. Da tappen 12 har en glidepasning med minimal frigang i røret 8, opfører tappen 10 12 sig på samme måde som et stempel og skubber beholderind- holdet i røret 8 foran sin frie ende og tilbage mod måleåbningen 7. Fremføringen af tappen 12 i røret 8 fortsætter med den aksiale nedføring af hætten 1 over halsen 3, indtil skulderen 13 på hætten 1 ligger an mod fladen 10 på proppen 2 som 15 definition på lukketilstanden for hætten 1, og da den aksiale længde L er mindre end den aksiale længde h, vil bevægelsen af tappen 12 langs røret 8 blive standset, før den frie ende af tappen 12 støder mod bunden af røret 8, og tappen 12 opnår derfor ikke at berøre måleåbningen 7.By closing the container, the cap 1 is placed on the neck 3 and the threads 4 and 5 are engaged with each other, and when the cap 1 is turned relative to the container C, the cap is axially lowered over the neck 3. With the threads 4 and 5 in the starting 5 engagement with one another, the pin 12 of the cap is positioned for axial insertion into the tube 8, and as the axial downward movement of the cap 1 over the neck 3 progresses, the pin 12 is inserted into the tube 8 and axially advanced within it. Since the pin 12 has a sliding fit with minimal clearance in the tube 8, the pin 10 12 behaves in the same way as a piston and pushes the container contents of the tube 8 in front of its free end and back towards the measuring opening 7. The feeding of the pin 12 in the tube 8 continues. with the axial lowering of the cap 1 over the neck 3, until the shoulder 13 of the cap 1 abuts the surface 10 of the plug 2 as a definition of the closure state of the cap 1, and since the axial length L is less than the axial length h, the movement will of the pin 12 along the tube 8 is stopped before the free end of the pin 12 abuts the bottom of the tube 8, and the pin 12 therefore fails to touch the measuring aperture 7.

20 Når hætten er i sin lukkede stilling, vil der således være en relativt lille mængde beholderindhold i røret 8 mellem den frie ende af tappen 12 og bunden af røret 8, idet resterende beholderindhold i røret 8, når dette lukkes af tappen 12, vil blive skubbet foran tappen 12, når denne fremføres i røret 25 8, og hvis mængden af beholderindholdet i røret 8 overstiger den mængde, der kan være i røret med tappen 12 ført helt ind, vil den overskydende mængde hurtigt flyde tilbage i beholderen gennem måleåbningen 7, således at beholderindhold i røret 8 ikke i urimelig grad hindrer fremføringen af tappen 12 i 30 røret 8 eller fremkalder uacceptabel modstand mod lukningen.Thus, when the cap is in its closed position, there will be a relatively small amount of container contents in the tube 8 between the free end of the pin 12 and the bottom of the tube 8, with remaining container contents in the tube 8, when closed by the pin 12, pushed in front of the pin 12 as it is fed into the tube 25 8, and if the amount of container contents of the tube 8 exceeds the amount that may be in the tube with the pin 12 fully inserted, the excess amount will quickly flow back into the container through the measuring aperture 7; so that container contents in the tube 8 do not unreasonably impede the advance of the pin 12 in the tube 8 or cause unacceptable resistance to the closure.

1 den anden udførelsesform vist med stiplede linier i fig.1 shows the second embodiment shown in broken lines in FIG.

2 er bundterne af børster 6 udeladt, og en ringformet væg 14, der rager frem fra fladen 10, udvider den aksiale længde af røret 8 i retning bort fra måleåbningen 7, så at lukningen 35 virker på samme måde som ved den første udførelsesform, idet2, the bundles of brushes 6 are omitted, and an annular wall 14 projecting from the surface 10 extends the axial length of the tube 8 in a direction away from the measuring aperture 7 so that the closure 35 acts in the same manner as in the first embodiment,

Claims

All other parts and dimensions are the same as in the first embodiment, except that the pin 12 is inserted earlier in the tube 8 during the downpouring of the cap 1 over the neck 3 and that the axial length of the pin 12 is in contact with the pin 5. the tube 8, when the cap is in its closed position, is larger. Such a design is suitable for a so-called drop dispensing container. As shown in FIG. 2, the inner edge of the annular wall 10 14 may be tore as at 15 to aid in inserting the pin 12 into the tube 8. It will be seen that in both of the above described embodiments, an effective closure of the container which will be close to liquids when the fit of the pin 12 in the tube 8 is designed as shown, without the container contents adversely affecting the fit between the pin 12 and the tube 8, and without creating unacceptable tension in the closure members. In addition, however, the closure device according to the invention has the advantage that when the pin 12 first closes the entrance to the tube 8, all container contents of the tube 8 are prevented from passing the free end of the pin 12, so that no discharge of the container contents occurs during the closure. , which is a significant advantage when the container contents are expensive materials. 25 Patent claims.
