Container for hermetically sealed storage of products, in particular foodstuffs

A receptacle for a hermetically sealed storage of liquid, paste, and/or solid products,

• the receptacle comprising;
• a product container open at an open side and a tear open end connected in an airtight manner to the open side of the product container via a beaded margin or via an adhesive connection, or a welded connection,
• wherein the open side of the product container has a first container curvature and a second container curvature diametrically opposed from the first container curvature,
• wherein the tear open end is reclosable,
• and comprises a composite material in the form of a sheet metal layer bonded to a plastic film;
• wherein the sheet metal layer and a lacquer film at a peripheral line of a respective provided opening region is pierced or punched through accordingly while forming a microgap;
• wherein the plastic film disposed on an inner receptacle side and closing the microgap is provided at a distance from the microgap with a weakening or with a notch extending at least regionally over a thickness of the plastic film;
• wherein a peripheral stiffening and coupling frame having at least one sealing and latching rib is fastened to an outer end side on a marginal region of an upwardly pivotable end region and that is bounded by the microgap;
• wherein a sealing frame that is engaged over by the stiffening and coupling frame is likewise fastened to an outer end side on a fixed end surface adjacent to the microgap and outside the opening region and has reception grooves for a sealing reception of the sealing and latching ribs provided at the stiffening and coupling frame,
• wherein the sealing frame has a first sealing frame curvature proximal to the first container curvature of the open side of the product container and a second sealing frame curvature proximal to the second container curvature of the open side of the product container,
• wherein a position of the sealing and latching ribs is swappable, and wherein a position of the reception grooves, is swappable;
• wherein an end part formed by the upwardly pivotable end region bounded by the microgap and by the stiffening and coupling frame fastened thereto is, provided with a tear open member connected in an articulated manner to an outer margin of the stiffening and coupling frame and is, fixedly connected to the fixed end surface disposed outside the upwardly pivotable end part via a pivot bearing region molded to the stiffening and coupling frame diametrically opposite said tear open member,
• wherein the pivot bearing region is proximal to the first container curvature of the open side of the product container and the tear open member is proximal to the second container curvature of the open side of the product container;
• wherein a radius of the first sealing frame curvature is different from a radius of the first container curvature, and wherein a radius of the second sealing frame curvature is the same as a radius of the second container curvature;
• and
• wherein an area of the opening region is at least fifty percent of an area of the open side of the product container.
