Description

. DK 2022 00002 U1 Beholderlukkeenhed, især beregnet til drikkevarebeholdere Opfindelsen angår en beholderlukkeenhed, især beregnet til drikkevarebeholdere, hvilken sikrer ikke-løsbar og stabil forbindelse mellem beholderen og låget.. The invention relates to a container closure unit, in particular intended for beverage containers, which ensures non-releasable and stable connection between the container and the lid.

For at opnå den hensigtsmæssige holdbarhed af fødevarer, som er pakket i beholdere med et låg, er det nødvendigt at opnå en lækagesikker og lufttæt forbindelse.To achieve the proper shelf life of foods packaged in containers with lids, it is necessary to achieve a leak-proof and airtight connection.

Kravet er især svært at opfylde i tilfælde af f.eks. drikkevareprodukter, især drikkevarer under tryk.The requirement is especially difficult to meet in the case of e.g. beverage products, in particular beverages under pressure.

Den sædvanlige anvendte metode til at opfylde det ovennævnte krav er anvendelsen af et ekstra materiale, som fremviser tætningsegenskaber i forbindelsesområdet mellem beholderen og dens låg i forbindelse med den termoplastiske formning af beholderen og låget.The commonly used method of meeting the above requirement is the use of an additional material which exhibits sealing properties in the connection area between the container and its lid in connection with the thermoplastic forming of the container and the lid.

Det skal dog understreges, at tætningsmaterialet kun kan udfylde sit formål, hvis låget og beholderen, når forbundne med hinanden, ikke deformerer som følge af trykket inden 1 beholderen og/eller beskadigelser under samleprocessen, hvor deformeringerne ville forårsage ændringer af selve forbindelsen, de nævnte ændringer består af dannelsen af spalter mellem tætningsmaterialet og låget, og/eller mellem tætningsmaterialet og beholderen, eller i total ødelæggelse af forbindelsen mellem beholderen og låget, hvilket uopretteligt eliminerer de lækagesikre og lufttætte egenskaber i forbindelsesområdet, og dette igen uopretteligt blotter beholderen for egenskaberne, som er uundværlige for opbevaring af produktet inden i og bevaring af dets korrekte holdbarhed.It should be emphasized, however, that the sealing material can only fulfill its purpose if the lid and the container, when connected to each other, do not deform due to the pressure within the container and / or damage during the assembly process, where the deformations would cause changes in the connection itself. changes consist of the formation of gaps between the sealing material and the lid, and / or between the sealing material and the container, or in total destruction of the connection between the container and the lid, which irreparably eliminates the leak-proof and airtight properties in the connection area, and this again irreparably exposes the container to the properties, which are indispensable for storing the product inside and preserving its proper shelf life.

I patentdokument US 4,487,326 A er beskrevet en plastikbeholder, som er lukket med et låg af fleksibel plastik, og er beregnet til drikkevarer under tryk.U.S. Pat.
