Sheet for closing aseptic containers, aseptic container comprising said sheet, and equipment and method for obtaining said container

Equipment for making an aseptic container,

• the container comprising a closing sheet and a body (1) of impermeable material defining a housing (6′) configured to contain an object (6), comprising a closing sheet (10) configured to seal the housing (6′), the perimetric edges of said closing sheet (10) being heat sealed to outer edges (1″) of the body (1) of the container in its entire perimeter, wherein the body (1) of the container is configured to be obtained from a sheet of multilayer film of polyester and/or polypropylene, the housing (6′) being defined by means of thermoforming or molding of said body (1), the equipment comprising:
• a frame (3),
• a lower reel (1′) comprising a film of impermeable material configured to obtain a body (1) of the container,
• a plurality of clamps (2) configured to hold two opposite perimetric edges of the film of impermeable material of the lower reel (1′),
• a forming mold (4) configured to thermoform a housing (6′) in the reel of film of impermeable material which will form a body (1),
• a first reel (7′) comprising a film of material that is permeable to ethylene oxide,
• a second reel (8′) comprising a film of an impermeable material,
• sealing jaws (9) configured to heat seal a longitudinal edge of the film of permeable material of the first reel to a longitudinal edge of the film of impermeable material of the second reel, through a sealing line, to form a closing sheet (10) comprising a first sheet (7) of material that is permeable to ethylene oxide and a second sheet (8) of impermeable material, the first sheet (7) and the second sheet (8) being overlapped through a first edge (7″) and (8″), respectively, forming the mentioned sealing line (18);
• a welding device (11) configured to heat weld the film of impermeable material of the second reel (8′), in a plurality of weld points (19), to the film of impermeable material configured to obtain a containing body of the container in outer edge (1″) of the body (1),
• a first sealing mold (12) configured to heat seal a second edge (7′″) of the first sheet (7) to the outer edges (1″) of the body (1), through a first area, at a first sealing temperature,
• a second sealing mold (12′) configured to heat seal a second edge (8′″) of the second sheet (8) to the outer edges (1″) of the body (1), through a second area, at a second sealing temperature different from the first sealing temperature.
