Description

Beholder med tilhørende lokk, som anbringes Container with associated lid, which is placed

ved hjelp av rotasjonssveising.using rotary welding.

Oppfinnelsen angår en beholder med tilhorende lokk, hvor minst kontaktflatene mellom beholderen og lokket er av plast The invention relates to a container with an associated lid, where at least the contact surfaces between the container and the lid are made of plastic

og hvor lokket er beregnet til å anbringes over en åpning i beholderen ved utovelse av trykk mellom lokk og beholder og rotasjon av lokket i forhold til beholderen, således at den friksjonsvarme som frembringes i beholderens og lokkets kontaktflater får minst en del av kontaktflatene til å smelte, hvoretter rotasjonen stanser og trykket holdes ved like inntil det smeltede materiale har stivnet. and where the lid is intended to be placed over an opening in the container by exerting pressure between the lid and the container and rotating the lid in relation to the container, so that the frictional heat produced in the contact surfaces of the container and the lid causes at least part of the contact surfaces to melt , after which the rotation stops and the pressure is maintained just until the molten material has solidified.

Ved sammenfdyning av deler av plast er det alminnelig kjent å anvende friksjonssveising. Denne fremgangsmåte er særlig anvendelig når kontaktflatene mellom plastdelene er sirkulære og den ene del roteres mens delene trykkes mot hverandre. Ved prak- tisering av rotasjonssveising ifolge den kjente teknikk sveises hele arealet av kontaktsidene sammen, slik at det tilveiebringes storst mulig sveisekontakt. When joining plastic parts, it is generally known to use friction welding. This method is particularly applicable when the contact surfaces between the plastic parts are circular and one part is rotated while the parts are pressed against each other. When practicing rotational welding according to the known technique, the entire area of the contact sides is welded together, so that the largest possible welding contact is provided.

Oppfinnerne har imidlertid funnet at lokket kan festes meget hurtig og forsvarlig til beholderen ifolge den nevnte fremgangsmåte dersom det gjores bruk av en beholder og et lokk der minst én av kontaktflatene er forsynt med et antall ringformede og konsentriske forhoyninger. Med dette arrangement oppnås konsentrerte smeltesoner som oppvarmes hurtig. Om derimot begge kontaktflater er jevne, eksempelvis plane eller kjegleformede flater, vil oppvarmings-forholdene variere i beroringssonene. Da beholderens kontaktflate ikke kan understottes av noe verktoy, er det vanskelig å få en jevn trykkbelastning på kontaktflatene. Trykkbelastningen vil sannsyn-ligvis variere med avstanden fra lokkets rotasjonssentrum. Det er derfor hensiktsmessig å konsentrere de aksielle trykk-krefter under forseglingsprosessen på små områder. De ringformede fremspring med-forer. et sikrere anlegg i f riks jonsf låtene, og således en bedre sveis. However, the inventors have found that the lid can be attached very quickly and safely to the container according to the aforementioned method if a container and a lid are used where at least one of the contact surfaces is provided with a number of annular and concentric elevations. With this arrangement, concentrated melting zones are achieved which heat up quickly. If, on the other hand, both contact surfaces are smooth, for example flat or cone-shaped surfaces, the heating conditions will vary in the contact zones. As the container's contact surface cannot be supported by any tool, it is difficult to get a uniform pressure load on the contact surfaces. The pressure load will probably vary with the distance from the lid's center of rotation. It is therefore appropriate to concentrate the axial pressure forces during the sealing process on small areas. The annular projections with liners. a more secure installation in the friction lines, and thus a better weld.

Disse forhoyninger har dessuten den fordel at slipestoff, splinter og fliser, som dannes under sveisingen, samles i det minste delvis mellom de nevnte forhoyninger, således at forurensning av beholderens innhold hindres så meget som mulig. These elevations also have the advantage that abrasive material, splinters and chips, which are formed during welding, are at least partially collected between the aforementioned elevations, so that contamination of the container's contents is prevented as much as possible.

Ethvert slipestoff eller flis som allikevel passerer for-høyningene, kan holdes tilbake ved å bruke en beholder med lokk hvor enten lokket eller beholderen er utstyrt med en ringformet fremst i.li-kende kant plassert nær den ytterkant av kontaktflaten som er nærmest åpningen. Denne ringformede fremstikkende kant passer fortrinns-vis fritt inn i et tilsvarende ringformet spor anordnet i enten lokket eller beholderen. Any abrasive or chips that do pass the elevations can be contained by using a container with a lid where either the lid or the container is provided with an annular leading edge located near the outer edge of the contact surface closest to the opening. This ring-shaped projecting edge preferably fits freely into a corresponding ring-shaped groove arranged in either the lid or the container.

I en fordelaktig utfbrelse av lokket og beholderen har minst en av de nevnte kontaktflater form som en avkortet konusflate. In an advantageous embodiment of the lid and the container, at least one of the mentioned contact surfaces has the shape of a truncated cone surface.

Oppfinnelsen skal nå forklares nærmere under henvisning til tegningene, der fig. 1 til 9 hver viser et tverrsnitt av en ut-forelsesform av oppfinnelsen. Alle figurer representerer den del av beholderen til hvilken lokket er festet. The invention will now be explained in more detail with reference to the drawings, where fig. 1 to 9 each show a cross section of an embodiment of the invention. All figures represent the part of the container to which the lid is attached.

I alle figurer betegner 1 beholderens sidevegg, 2 endeveggen, 3 åpningen og k lokket. In all figures, 1 denotes the side wall of the container, 2 the end wall, 3 the opening and k the lid.

I utfbrelsesformen i fig. 1 er et lokk h utstyrt med en plan ringformet kontaktflate 5 avpasset til å samvirke med en kontaktflate 6 som har form av en avkortet konus. Kontaktflaten 5 er utstyrt med et antall ringformede og konsentriske forhøyninger 7. In the embodiment in fig. 1 is a cover h equipped with a planar ring-shaped contact surface 5 adapted to cooperate with a contact surface 6 which has the shape of a truncated cone. The contact surface 5 is equipped with a number of annular and concentric elevations 7.

En fremstikkende ringformet kant 57 av lokket k griper bak en ringformet kant 58 ved den indre begrensning av kontaktflaten 5^ som er plassert nær åpningen 3. The embodiment according to fig. 9 is equipped with conical contact surfaces 5^°g 55", of which the contact surface 55 has annular concentric elevations 56. A projecting annular edge 57 of the cover k engages behind an annular edge 58 at the inner limit of the contact surface 5^ which is located near the opening 3.

Lokket festes på en væske- og gasstett måte ved at det anbringes på åpningen 3 på en sådan måte at beholderens og lokkets kontaktflater stoter mot hverandre. Derpå utoves trykk på lokket l+, f.eks. ved hjelp av en aksel som er bevegelig i rett vinkel med lokket, mens akselen roteres. Akselens ende og lokket er formet således at lokket gripes av akselen og folgelig også roteres. For dette oyemed kan lokket k være utstyrt med egnede fordypninger eller kammer (ikke vist). Under lokkets h rotering holdes beholderens stasjonær således at lokket roteres i forhold til beholderen. Denne rotasjon forårsaker at varme utvikles på kontaktflatene og denne varme bringer materialene i kontaktflatene til å smelte i noen grad. Etterr at til-strekkelig smelting er inntruffet, bringes akselen og lokket til å stoppe mens derimot trykket som utoves på lokket vedlikeholdes i noen tid, dvs. inntil det. smeltede materiale igjen er stivnet. Når materialet er stivnet er lokket forsvarlig forenet med beholderen og på en væske- og gasstett måte. The lid is fixed in a liquid- and gas-tight manner by placing it on the opening 3 in such a way that the contact surfaces of the container and the lid butt against each other. Then also press on the lid l+, e.g. by means of a shaft which is movable at right angles to the lid, while the shaft is rotated. The end of the shaft and the lid are shaped so that the lid is gripped by the shaft and consequently also rotated. For this reason, the lid k can be equipped with suitable recesses or chambers (not shown). During the lid h rotation, the container is kept stationary so that the lid is rotated in relation to the container. This rotation causes heat to develop on the contact surfaces and this heat causes the materials in the contact surfaces to melt to some extent. After sufficient melting has occurred, the shaft and the lid are brought to a stop, while, on the other hand, the pressure exerted on the lid is maintained for some time, i.e. until then. melted material is again solidified. When the material has solidified, the lid is properly united with the container and in a liquid and gas tight manner.

På grunn av de ringformede konsentriske forhoyninger smelter kontaktflatenes materiale meget hurtig under den nevnte ope-rasjon. Enhver flis, splint eller slipestoff av materialet som frem-kommer under operasjonen, samles i stor utstrekning i "fordypningene" mellom de ringformede forhoyninger, og som et resultat herav hindres de fra å finne vei inn i beholderens innhold og fra å forurense dette. En ekstra sikkerhet mot forurensning av beholderens innhold ved fliser, splinter eller slipestoff av materialet kan oppnås ved å bruke en ringformet fremstikkende kant 8, IK, 19, 27, 32, k6, 52 eller 58 plassert nær den avgrensning av kontaktflaten 6, 11, 17»23»29, h2, hy eller 50 som er nærmest den nevnte åpning. Kanten kan f.eks. rage inn i et ringformet spor 9»15»18, 26, 33 eller gripe bak en ringformet kant 1+7, 53 eller 57-Den nevnte f remstikkende kant tilbake-holder enhver flis, splint eller slipestov som er fremkommet og danner derfor en ekstra sikkerhet mot forurensning av beholderens innhold. Because of the ring-shaped concentric elevations, the material of the contact surfaces melts very quickly during the aforementioned operation. Any chips, splinters or abrasives of the material that emerge during the operation are collected to a large extent in the "recesses" between the annular elevations, and as a result are prevented from finding their way into the contents of the container and from contaminating it. An additional security against contamination of the container's contents by chips, splinters or abrasives of the material can be achieved by using an annular projecting edge 8, IK, 19, 27, 32, k6, 52 or 58 located close to the boundary of the contact surface 6, 11, 17»23»29, h2, hy or 50 which is closest to the aforementioned opening. The edge can e.g. protrude into an annular groove 9»15»18, 26, 33 or grip behind an annular edge 1+7, 53 or 57 - The aforementioned protruding edge retains any chip, splinter or sanding residue that has appeared and therefore forms a extra security against contamination of the container's contents.

I utforelsesformen ifolge fig. 6 er en slik fremstikkende ringformet kant ikke anordnet. I dette tilfelle er kontaktflatene 35 og 36 arrangert på en sådan måte at de sammen har V-formet tverrsnitt. Med andre ord danner flatene 35°g 36 sammen en V-formet ka- nal hvor fliser, splinter eller slipestoff som er frigjort kan samles. In the embodiment according to fig. 6, such a projecting ring-shaped edge is not arranged. In this case, the contact surfaces 35 and 36 are arranged in such a way that they together have a V-shaped cross-section. In other words, the surfaces 35°g 36 together form a V-shaped channel where chips, splinters or abrasive material that has been released can be collected.

Beholderen kan brukes for gass- eller væsketett pakning av pulverformige materialer eller av væsker, f.eks. for pakning av smbreolje. The container can be used for gas- or liquid-tight packaging of powdery materials or of liquids, e.g. for packing oil.
