Container and method for producing such a container

Method for producing a container having a mouth opening defined by the upper part of the peripheral wall and a membrane lid arranged with an attachment zone on the edge of the mouth opening for closing the container, wherein the method comprises the steps of:

• providing a container with a bottom and a peripheral wall;
• providing a first plastic onto the edge of the mouth opening, defined by the peripheral wall, wherein the first plastic substantially absorbs the energy of a laser beam;
• providing a membrane lid having an attachment zone for attachment to the edge of the mouth opening, wherein the attachment zone of the membrane lid consists over its thickness of a second plastic, which is substantially transparent for the laser beam;
• arranging the membrane lid onto the edge of the mouth opening and guiding the laser beam along and through the attachment zone onto the first plastic, such that the energy of the laser beam is dissipated in the first plastic and the generated heat causes the first plastic and the second plastic to fuse.

A container, comprising:

• a horizontal container bottom;
• a vertical container wall extending from and attached to the horizontal container bottom at a first end of the wall and forming a container mouth opening in the form of a ring at a second end of the wall;
• a circular attachment zone component connected to the ring on an outer circumference of the circular attachment zone component and extending into the container mouth with an inner circumference of the circular attachment zone component, the circular attachment zone component comprising a circular planar surface;
• a circular polymeric connecting layer fused to the circular planar surface;
• and
• a transparent lid, fused to the circular connecting layer sealing the container.
