Description
7808177-5 10' 15 20 25 30 35 2 Sammanfattning av uppfinningen Ett ändamål med föreliggande uppfinning är att åstadkomma ett behållarlock, som kan öppnas utan att man behöver använda några särskilda öppnare och som lätt kan framställas till låg kostnad. SUMMARY OF THE INVENTION An object of the present invention is to provide a container lid which can be opened without the need to use any special openers and which can be easily manufactured at low cost.
Ett annat ändamål med föreliggande uppfinning är att åstadkomma ett lock, som kan framställas genom att syntetisk termoplast insprutas i försvagade delar, såsom ett genomgående hål, genomgående hål, skåror eller inskärningar i ett i förväg format lockråämne med en dragflik för bildning av en öppning, varigenom locket lätt kan öppnas.Another object of the present invention is to provide a lid which can be made by injecting synthetic thermoplastic into weakened parts, such as a through hole, through hole, grooves or notches in a preformed lid blank with a pull tab to form an opening. whereby the lid can be easily opened.
Ett annat ändamål med uppfinningen är att åstadkom- ma ett behållarlock, som har en dragflik, som fungerar såsom öppnings- och stängningsplugg, som kvarhàlles på locket också sedan behållaren öppnats.Another object of the invention is to provide a container lid which has a pull tab which acts as an opening and closing plug which is retained on the lid even after the container has been opened.
Ett ytterligare ändamål med uppfinningen är att anvisa ett sätt att framställa ett behållarlock till låg kostnad, varvid behållaren lätt kan öppnas utan att man använder någon särskild öppnare. Ändamàlen med uppfinningen uppnås medelst ett sätt och en anordning, som har de i patentkraven an- givna kännetecknen.A further object of the invention is to provide a method of manufacturing a container lid at low cost, whereby the container can be easily opened without using any special opener. The objects of the invention are achieved by means of a method and a device which have the features stated in the claims.
De angivna ändamålen och andra ändamål och för- delar med uppfinningen kommer klarare att framgå för fackmannen efter läsning av följande detaljerade be- skrivning tillsammans med åtföljande ritning, vilken visar en föredragen utföringsform av uppfinningen i belysande syfte utan avsikt att begränsa uppfin- ningens omfattning på något sätt.The stated objects and other objects and advantages of the invention will become more apparent to those skilled in the art upon reading the following detailed description taken in conjunction with the accompanying drawings, which illustrate a preferred embodiment of the invention for illustrative purposes without limiting the scope of the invention. some way.
Kort beskrivning av ritningarna Fig l är en planvy av locket med en öppningsdel, som är markerad av en serie skåror i väsentligen en riktning och som upptar en väsentlig del av täckskik- tets yta enligt uppfinningen. Fig 2 är ett tvärsnitt, som tagits väsentligen längs linjen IV-IV i fig 1. -a 10 15 20 25 30 35 7808177-5 3 Föredragna utföringsformer av uppfinningen Uppfinningen kommer nu att beskrivas med hänvis- ning till bifogade ritningar.Brief description of the drawings Fig. 1 is a plan view of the lid with an opening part, which is marked by a series of grooves in substantially one direction and which occupies a substantial part of the surface of the cover layer according to the invention. Fig. 2 is a cross-section taken substantially along the line IV-IV in Fig. 1. Preferred Embodiments of the Invention The invention will now be described with reference to the accompanying drawings.
Enligt fig 1 och 2 upptar en öppningsbar del 20 av ett lock 10 en väsentlig del av mittomràdet av ett täckskikt ll och slitsar 21, som har diskonti- nuerliga delar 22, löper i en riktning längs en väsent- lig del av täckskiktets ll periferi för att markera en väsentlig del av öppningen 20 och slutar i en dis- kontinuerlig del 28 utan att någon fullständig ring- form bildas. Det på detta sätt förformade lockráämnet placeras i en formsprutningsmaskin, vari syntetharts insprutas i slitsarna 21 pà motsatta ytor av täckskik- tet ll för att i ett stycke bilda förslutningar 23, som vardera har nithuvuden 24, 25 pá motsatta ytor av täckskiktet ll och även bilda kontinuerliga harts- partier 26, som förenar intilliggande nithuvuden 24, 25. De pá detta sätt bildade delarna utgör en samman- hängande ringformig kontinuerlig bandformad zon 27, som ett helt pá var och en av täckskiktets motsatta ytor. Vid formsprutningen av hartset bildas också ett handtag 30 i ett stycke med den ringformade band- formade öppningszonen 27 pá en av de motsatta ytorna av täckskiktet ll (den yttre ytan av täckskiktet).According to Figs. 1 and 2, an openable part 20 of a lid 10 occupies a substantial part of the central area of a cover layer 11 and slits 21 having discontinuous parts 22 run in a direction along a substantial part of the periphery of the cover layer 11 for to mark a substantial portion of the opening 20 and terminate in a discontinuous portion 28 without forming a complete annular shape. The lid blank preformed in this way is placed in an injection molding machine, in which synthetic resin is injected into the slots 21 on opposite surfaces of the cover layer 11 to form in one piece closures 23, each having rivet heads 24, 25 on opposite surfaces of the cover layer 11 and also forming continuous resin portions 26 joining adjacent rivet heads 24, 25. The portions thus formed form a continuous annular continuous strip-shaped zone 27, as a whole on each of the opposite surfaces of the cover layer. During the injection molding of the resin, a handle 30 is also formed in one piece with the annular strip-shaped opening zone 27 on one of the opposite surfaces of the cover layer 11 (the outer surface of the cover layer).
Då handtaget 30 drages uppåt i förhållande till resten av locket delar öppnandet av de kontinuerliga bandformade zonerna 27 täckskiktet ll i innerdelen eller öppningen 20, av vilka en väsentlig del av peri- ferin avskiljes frán täckskiktet och den kvarvarande delen 28 fungerar som led, runt vilken den öppnings- bara delen öppnas eller slutes.When the handle 30 is pulled upwards relative to the rest of the lid, the opening of the continuous band-shaped zones 27 divides the cover layer 11 into the inner part or the opening 20, of which a substantial part of the periphery is separated from the cover layer and the remaining part 28 acts as a joint around which the openable part opens or closes.
Pà detta sätt kan den stora öppningen, genom vilken en sked eller liknande kan införas i behålla- ren, ej endast lätt öppnas utan öppningen är så anordnad att den öppningsbara del, som avgränsar öppningen, kastas alltid tillsammans med behållaren. 7808177-5 4 Uppfinningen har visats och beskrivits i detalj men denna utföringsform är avsedd att belysa uppfin- ningen och skall ej fas som en definition av uppfin- ningen, vilken uppfinning definieras i bifogade krav.In this way, the large opening, through which a spoon or the like can be inserted into the container, can not only be easily opened but the opening is arranged so that the openable part, which delimits the opening, is always thrown together with the container. The invention has been shown and described in detail, but this embodiment is intended to illustrate the invention and should not be construed as a definition of the invention, which invention is defined in the appended claims.
