Patent ID: 7743811

Claim:
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.
