    handles 6 of the package 1, includes a tension-removing ring 7 sewn to the protective wrap 5, surrounding the valve 3b to avoid tearing when handling the container 1.
    Figures 2 to 4 and 7 show different views of the claimed valve 3a, 3b comprising a fluid inlet and / or outlet conduit 8 provided with a fluid flow regulating element 9, and a seat 10 for said conduit 8 fluid inlet and / or outlet comprising a coaxial base 10a provided with a surface 10b to be attached to a portion of the inner sheath 4 of flexible material of the container 1, for example, by welding of both materials (see Figure 7).
    In the described embodiment, the seat 10 of the fluid inlet and / or outlet duct 8 includes a wall 23 provided with a hole 24 for access of a probe (not shown) for sampling inside the container 1. Figure 7 shows a plan view of the wall 23 and the hole 24 through which the said probe is inserted. The hole 24 is covered superiorly by the inner sheath 4 of flexible material and inferiorly by a polyurethane rubber, or any other elastomeric material configured to seal the hole 24, once the probe is removed.
    In addition to said seat 10, the valve body 3a, 3b includes a cover 11 to cover said seat 10, which is provided with an orifice 12 for access to the inlet and / or fluid outlet conduit 8. As can be seen in Figures 3 and 4, this cover 11 includes a plurality of projections 13 distributed around the fluid inlet and / or outlet conduit 8, on a surface of the coaxial base 10a of the seat 10 surrounding said conduit 8. The projections 13 are arranged to cooperate with recesses 14 provided on the inner face of the lid 11, so that these projections 13 can pass through a portion of the protective wrap 5 to be inserted in the recesses 14, safely imprisoning the protective wrap 5 between the seat 10 and the cover 11. In the final position of use of the valve 3 shown in Figure 2, the cover 11 covers the seat 10 protecting the union of the inner sheath 4 with the seat 10 and simultaneously holding The wrapper 5 protector.

    fluid, a plug 19 is provided at the upper end of the fluid inlet and / or outlet duct 8 protruding from the upper face of the coaxial base 10a and is arranged in correspondence with the access hole 12 of the cover 11.
    The plug 19 comprises grooves 20 in the inner wall that are coupled to projections 21 of the outer wall of the fluid inlet and / or outlet conduit 8 determining two closing positions (see figures 5a and 5b). In a first position shown in Figure 5a, the plug 19 is coupled at the end of the fluid inlet and / or outlet duct 8 in a provisional or pre-closing position that prevents the entry of dust and foreign material into the inside the container 1 before injecting or extracting fluid inside. In a second closed position shown in Figure 5b, the same plug 19 is inserted into the end of the fluid inlet and / or outlet conduit 8, until it is fully adjusted to ensure the tightness of the inner atmosphere of the container and the inviolability of the valve 1.
    Figure 3 shows the fluid flow regulating element 9 of the valve 3a, 3b which, in the described embodiment, is configured by a membrane of elastomeric material provided with a removable shape insert 22 in a hole 25 of a wall 26 inside the conduit 8 for fluid inlet and / or outlet. The same transverse wall 26 includes a pair of holes 27 for the passage of the fluid. In a rest position, the membrane is adhered to the transverse wall 26 blocking the fluid passage.
    In Fig. 3, the membrane has been shown attached to the upper face of the transverse wall 26, so that the force of the gas flow being sucked through the holes 27 raises the membrane to allow the suction gas to escape through conduit 8 for fluid inlet and / or outlet. Figure 4 shows a support 28 attachable to the inner end of the fluid inlet and / or outlet conduit 8 which is provided with a filter 29 that prevents the entry of materials and / or dust into the fluid extraction equipment or device.
    As mentioned in the description of the invention, the claimed package 1 comprises an inner sheath or liner for selling wholesale merchandise that includes one or more layers or sheets of flexible material, for example a polyethylene sheet and / or an aluminum foil. At least one of said sheets has adequate permeability to keep the composition of the inner atmosphere of the container 1 substantially constant for a predetermined time, once the gas has been injected and the valves 3a, 3b closed. This inner cover 4 or "liner" is in direct contact with the merchandise and is
    eleven

    35
    attached to a protective wrap 5 that can also be made of flexible material or a semi-rigid material such as cardboard.
    The operation of the container 1 and the claimed valve 3a, 3b is described below.
    As mentioned, the goods are pre-packaged in a conventional filling and packaging line, proceeding to hermetically close the container 1 by, for example, heat sealing applied to polyethylene sheets that are part of the sheath 4 inside of the container 1.
    Once the container 1 is hermetically sealed with the merchandise inside, the air is extracted from the interior space of the container 1 by means of an air extraction unit of the fluid extraction and / or injection device, coupling the element 16 of interconnection of the device with the inlet and / or fluid outlet 8 of one of the valves 3b, through the hole of the cover 11. The aspiration is carried out through this valve 3b until a certain level of vacuum is achieved. The end of the fluid inlet and / or outlet duct 8 incorporates a filter 29 to filter the extracted air.
    Then, or simultaneously, by keeping an interconnection element 16 coupled to the fluid inlet and / or outlet conduit 8 of another valve 3a, gas or any other fluid is injected into the interior space of the container 1.
    Both gas injection and air extraction are carried out under the supervision of a processing and control unit that receives information from an online analysis unit of the interior atmosphere of the container 1. This analysis is performed on a sample of gas obtained directly through one or both valves 3a, 3b by introducing a probe (not shown). Once the processing and control unit verifies that the concentration of the atmosphere is as desired, the injection is stopped and the valves 3a, 3b are closed.
    Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described valve and container are susceptible of numerous variations and modifications, and that all the mentioned details can be substituted by others technically equivalent, without departing from the scope of protection defined by the appended claims. For example, although the embodiment described and represented in the figures refers to a package that includes a protective wrap formed by
    12
    a sheet of flexible material, the claimed valve could also be applied to a container with a cardboard protective wrap that would also be trapped between the lid and the valve seat. However, in this case the recesses and projections of the cover and the seat would be of a greater length to be able to pass through a sheet of cardboard about 7 to 5 12 mm thick.
