Description
Forseglings- og tettings-ring av kunststoff for bokser. Sealing and sealing ring made of plastic for cans.
Det er tidligere kjent forseglings- og It is previously known sealing and
tettingsringer av formet kunststoff, som skal festes, f. eks. ved falsing, dels på en bokssarg og dels på et lokk som lukker boksen, for å forbinde sargen og lokket og sikre en vakuumtett lukking. Disse ringer har dels to omkretsriveriller som mellom seg begrenser et bånd som skal kunne rives av når boksen åpnes første gang og dels en tunge som er utført i ett stykke med par-tiet mellom de to riller og som skal tjene til å rive opp dette bånd. sealing rings made of shaped plastic, to be attached, e.g. by folding, partly on a box rim and partly on a lid that closes the box, to connect the rim and the lid and ensure a vacuum-tight closure. These rings partly have two circumferential grooves which between them limit a strip which must be able to be torn off when the box is opened for the first time and partly a tongue which is made in one piece with the part between the two grooves and which will serve to tear up this strip .
Formingen av en slik ring med sin tunge byr på følgende vanskeligheter: Formingen må foretas ved hjelp av en skyve-form og oppgaven er å gi tungen en slik utforming at når først ringen og tungen er tildannet i ett stykke, kan formen igjen åpnes, dvs., at skyve-bakkene kan fjernes fra kjernen i formen. Disse vanskeligheter er tidligere ikke overvunnet. The shaping of such a ring with its tongue presents the following difficulties: The shaping has to be done using a push mold and the task is to give the tongue such a design that once the ring and the tongue have been formed in one piece, the mold can be opened again, i.e. ., that the sliding trays can be removed from the core of the mould. These difficulties have not previously been overcome.
Foreliggende oppfinnelse går ut på en The present invention is based on a
ring som er utformet slik at disse vanskeligheter forsvinner, nemlig ved at båndet i nærheten av tungeroten over hele sin bredde har en tykkelse som avtar gradvis mot tungeroten, for å lette begynnelsen av rivningen, idet den ytre overflate av båndet på dette avtynnede parti, på det tynneste sted på båndet danner en tangent til en sylinder som er koaksial med ringen. ring which is designed in such a way that these difficulties disappear, namely in that the band near the root of the tongue over its entire width has a thickness that decreases gradually towards the root of the tongue, in order to facilitate the beginning of tearing, since the outer surface of the band on this thinned part, on the thinnest point of the band forms a tangent to a cylinder coaxial with the ring.
På vedføyete tegning er det som eksempel vist en utførelsesform for ringen i henhold til oppfinnelsen og en form for fremstilling av denne. Fig. 1 viser et perspektivriss av en del av en sylinderformet metallboks med lokk og en ring i denne utførelsesform. Fig. 2 viser et del-lengdesnitt, i stor målestokk, av boksen, av dens lokk og ringen. Fig. 3 viser et deltverrsnitt gjennom den skyveform som brukes for fremstilling av den ring som er vist i fig. 1 og 2, med formen lukket og ringen formet inne i formen. Fig. 4 viser de samme organer som i fig. 3, men i åpen tilstand av formen, mens ringen ennå befinner seg på kjernen i formen. Fig. 5 viser et riss etter linjen 5—5 i The attached drawing shows, as an example, an embodiment of the ring according to the invention and a form of its manufacture. Fig. 1 shows a perspective view of part of a cylindrical metal box with a lid and a ring in this embodiment. Fig. 2 shows a partial longitudinal section, on a large scale, of the box, of its lid and the ring. Fig. 3 shows a partial cross-section through the push mold used for the production of the ring shown in fig. 1 and 2, with the mold closed and the ring formed inside the mold. Fig. 4 shows the same organs as in fig. 3, but in the open state of the mold, while the ring is still on the core of the mold. Fig. 5 shows a drawing along the line 5—5 i
fig. 4. fig. 4.
Fig. 6 viser et del-tverrsnitt av den ring som er vist i fig. 3 og 4, men etter deformering av tungen. Fig. 6 shows a partial cross-section of the ring shown in fig. 3 and 4, but after deforming the tongue.
Ringen 1 er av støpt eller formet kunststoff og skal kunne festes ved hjelp av en fals 2 på sargen 3 for en sylinderformet metallboks. Den skal dessuten kun- . ne festes ved hjelp av en fals 4 på lokket 5 som også er av metall og som lukker boksen. Denne ring har til oppgave å feste sargen 3 og lokket 5 til hverandre, å sikre vakuumtett lukking av boksen og dessuten å forsegle boksen. Ved forsegling skal det forstås at boksen ikke skal kunne åpnes uten at ringen brytes, slik at uberettiget åpning og gjenlukking av boksen ikke kan finne sted uten at det merkes. The ring 1 is made of molded or shaped plastic and must be able to be fixed by means of a seam 2 on the rim 3 for a cylindrical metal box. It must also only ne is fixed by means of a fold 4 on the lid 5 which is also made of metal and which closes the box. The task of this ring is to attach the rim 3 and the lid 5 to each other, to ensure a vacuum-tight closure of the box and also to seal the box. By sealing, it must be understood that the box must not be opened without the ring breaking, so that unauthorized opening and reclosing of the box cannot take place without being marked.
Ringen 1 har på kjent måte to rive-riller 6, 7 som løper parallelt rundt omkret-sen og som mellom seg begrenser et bånd 8 som skal kunne rives bort når boksen åpnes for første gang. Det er klart at ved denne avrivning blir ringen revet opp langs rillene 6 og 7. En tunge 9 som fremstilles sammen med ringen 1 og i ett stykke med båndet 8 tjener til å rive løs båndet. The ring 1 has, in a known manner, two tearing grooves 6, 7 which run parallel around the circumference and which between them limit a band 8 which must be able to be torn away when the box is opened for the first time. It is clear that during this tearing off the ring is torn up along the grooves 6 and 7. A tongue 9 which is produced together with the ring 1 and in one piece with the band 8 serves to tear the band loose.
Den ring som er vist skiller seg fra kjente utførelser ved følgende trekk: Båndet 8, som er vist i snitt i fig. 3 og 4 har på det parti som ligger nær roten 10 av tungen 9, over hele sin bredde en tykkelse som avtar gradvis mot denne rot, for å lette begynnelsen av avrivningen. Den ytre overflate 11 av båndet 8 danner på dette avtynnete parti, på stedet 12 med minste båndtykkelse en tangent til en geo-metrisk sylinder som er koaksial med ringen. Forbindelseslinjen mellom roten 10 for tungen 9 og båndet 8, på den siden hvor dette er avtynnet, har form som en vinkel 13 hvis topp-punkt ligger midt på båndet 8 på det sted hvor dette er tynnest. Hver av endene 14 og 15 av vinkelen faller sammen med bunnen av en av opprivningsril-lene 6, 7. Avtynningen av båndet 8 ved 12 og skråningen av linjen 13 letter igangset-tingen av avrivningen fra 12 langs 13. Ved at endene 14, 15 av linjen 13 faller sammen med bunnen av rillene 6, 7 vil opprivningen fortsette langs disse riller. For å fremstille den ring som er beskrevet, brukes det en skyve-form med kjerne 16 og skyve-deler 17 og 18. The ring shown differs from known designs in the following features: The band 8, which is shown in section in fig. 3 and 4 have, on the part which lies close to the root 10 of the tongue 9, over its entire width a thickness which gradually decreases towards this root, in order to facilitate the beginning of the tear-off. The outer surface 11 of the band 8 forms on this thinned part, at the place 12 of smallest band thickness, a tangent to a geometric cylinder which is coaxial with the ring. The connecting line between the root 10 of the tongue 9 and the band 8, on the side where this is thinned, has the shape of an angle 13 whose top point lies in the middle of the band 8 at the place where this is thinnest. Each of the ends 14 and 15 of the angle coincides with the bottom of one of the tear-off grooves 6, 7. The thinning of the band 8 at 12 and the slope of the line 13 facilitate the initiation of the tear-off from 12 along 13. In that the ends 14, 15 of the line 13 coincides with the bottom of the grooves 6, 7, the tearing will continue along these grooves. To produce the ring described, a push mold with core 16 and push parts 17 and 18 is used.
For å tildanne tungen 9 og det avtynnete parti 19, fig. 3 av ringen har den ytre del 17 av formen et bladformet parti 20 med to overflater 21, 22 som er stort sett plane og parallelle. Disse flater er dessuten parallelle med den avvekslende bevegelsesretning for trekkdelene. Når delen 17 er i arbeidsstilling, fig. 3, danner flatene 21, 22 tangenter til geometriske sy-lindre som er koaksiale med kjernen i formen. Flaten 21 er anordnet for å tildanne overflaten 11, dvs. avtynningen av rivebån-det 8, mens flaten 22 skal tildanne den innvendige overflate 23 av tungen 9. På grunn av denne tangentiale anordning av flatene 21, 22 er det klart at delen 17 kan fjernes fra kjernen etter formingen uten noen vanskelighet. Denne anordning danner en særlig enkel og sikker løsning på den formingsoppgave som ikke tidligere er blitt, løst, slik som nevnt i innledningen. To form the tongue 9 and the thinned part 19, fig. 3 of the ring, the outer part 17 of the mold has a leaf-shaped part 20 with two surfaces 21, 22 which are generally flat and parallel. These surfaces are also parallel to the alternating direction of movement of the traction parts. When part 17 is in working position, fig. 3, the surfaces 21, 22 form tangents to geometric sewing cylinders which are coaxial with the core of the mold. The surface 21 is arranged to form the surface 11, i.e. the thinning of the tear web 8, while the surface 22 is to form the inner surface 23 of the tongue 9. Because of this tangential arrangement of the surfaces 21, 22, it is clear that the part 17 can removed from the core after forming without any difficulty. This device forms a particularly simple and safe solution to the forming task that has not previously been solved, as mentioned in the introduction.
Delen 18 omfatter et parti som har en overflate 24 med stort sett plan form, som skal tildanne utdanne utsiden 25 av tungen 9. I dette eksempel er flaten 25 paral-lell med flatene 21 og 22 og med den avvekslende bevegelsesretning for delen 18, som er den samme som for delen 17. The part 18 comprises a part which has a surface 24 of generally planar shape, which is to form the outer side 25 of the tongue 9. In this example, the surface 25 is parallel to the surfaces 21 and 22 and to the alternating direction of movement of the part 18, which is the same as for section 17.
I det eksempel som er vist, har flatene In the example shown, the surfaces have
23 og 25 på tungen svake rifler for å lette 23 and 25 on the tongue weak rifles to lighten
opprivning av båndet. Disse rifler gjør det lettere å gripe tungen med fingrene under opprivningen. tearing of the bond. These riffles make it easier to grip the tongue with your fingers during the rip.
I fig. 6 er tungen 9 vist lagt ned mot utsiden av ringen 1. Denne nedlegging foretas etter formingen, f. eks. ved at tungeroten 10 gjøres bløt ved oppvarmning og at det deretter utøves et radialt trykk på tungen. Denne deformering av tungen har bare til hensikt å hindre at den skal ska-des under innpakning eller transport av boksen. In fig. 6, the tongue 9 is shown laid down towards the outside of the ring 1. This laying down is done after forming, e.g. in that the root of the tongue 10 is made soft by heating and that a radial pressure is then exerted on the tongue. This deformation of the tongue is only intended to prevent it from being damaged during wrapping or transport of the box.
Ringen kan forøvrig også festes på boksen og på lokket, ikke ved hjelp av fal-ser, men ved klebing eller sveising. Boksen og lokket trenger ikke å være sylinderformet. De kan også være utført av annet ma-terial enn metall, f. eks. av plast. Incidentally, the ring can also be attached to the box and the lid, not with the help of seams, but by gluing or welding. The box and lid do not have to be cylindrical. They can also be made of materials other than metal, e.g. of plastic.
