## Abstract

The present invention relates to a closing sheet for aseptic containers, aseptic container comprising said sheet, equipment and method for obtaining said container. The closing sheet comprises a first sheet (7) configured to be traversed by ethylene oxide and a second sheet (8) of impermeable material. The first sheet (7) is obtained from a first reel (7′) of film of material that is permeable to ethylene oxide and the second sheet (8) is obtained from a second reel (8′) of film of impermeable material. The first sheet (7) is longitudinally sealed to the second sheet (8) through a sealing line (18), thus forming a single closing sheet (10).

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

Equipment according to claim 1, wherein the first sealing mold (12) and the second sealing mold (12′) are configured to heat seal the first sheet (7) to the outer edges (1″) and the second sheet (8) to the outer edges (1″) simultaneously.

### Claim 3 (depends on 1)

Equipment according to claim 1, wherein the second sealing mold (12′) is configured to heat seal the second edge (7′″) of the first sheet (7) to outer edges (1″) of the body (1), through a first area, at the second sealing temperature.

### Claim 4 (depends on 1)

Equipment according to claim 1, further comprising:
a side cutting module (15) configured to cut surplus sides of the closed container,
a longitudinal cutting module (16) configured to cut surplus longitudinal edges of the closed container,
a device configured to collect the surplus of film of the process;
at least one conveyor belt (20) configured to move the obtained containers in the equipment.
