    A flat, flexible, sterilizable container for a liquid to be maintained and extracted under sterile conditions, said container comprising: a body having walls formed by a three-layer laminate including an outermost layer of a propylene polymer, an innermost layer of a copolymer of ethylene with a small amount of butylene, and an intermediate layer of an amide polymer; and a valve carried by said body comprising an elastomeric core whose spaced major faces are covered, one, by a three-layer laminate similar to said body wall forming laminate and, the other, by a two-layer laminate including a first layer of a copolymer of ethylene with little butylene and a second layer of an amide polymer.

    专利说明:

    The invention relates to elastic flat containers made of plastic, ensuring the liquid content in them, mainly pharmaceutical, recovered in absolutely sterile conditions. The purpose of the invention is to prevent liquid contamination by decomposition products. Fig. 1 shows a flat elas-O. A typical container for sterile liquid content, top view in Fig. 2, section A-A in Fig. 1, fig. 3, an elastomeric valve, viewed from above; figure 4 - section bb in fig.Z; in FIG. 3, an elastomer valve with corresponding plastic coatings; in FIG. 6, the same with the emptying needle disposed therein; The flat elastic container for sterile liquid containment comprises a housing whose walls 1 are welded at least from two the sides of the cross seams 2 and 3 with the formation of the cavity 4 for the reception and content of the liquid. An elastomer valve 5 having a disk shape is welded to the body of the container. The walls 1 of the housing are made of a three-layer plastic comprising an outer layer 6 containing a propylene polymer, an inner layer 7 containing an ethylene-butylene copolymer in an amount of 90-99% and 1-10%, respectively, and an intermediate layer 8 of amide polymer. One of the surfaces of the valve 5 is coated with a three-layer plastic 9 of the specified composition, and the other surface is covered with a two-layer plastic 10, including a layer 11 of copolymer of ethylene and butylene in the amount of 90-99% and 1-10%, respectively, and a layer 12 of amide polymer . The specified layers of two-layer and three-layer
    plastics are welded one to the other.
    The amide polymer from which layer 12 is made is oriented along two axes.
    Said amide polymer is polyamide-6.
    Each of the layers 8 and 12 of the amide polymer can be combined with the inner 7 and outer 6 layers: and and with the layer 11, respectively, using polyurethane.
    Elastomer valve 5 is made of a mixture of butyl and natural Kavchukov in the amount of 10-40%. On the upper and lower surfaces of the valve 5, protruding edges 13 are made, in which recesses 14 are made, with
    during the process of emptying the container, the latter is almost completely emptied, since the walls 1 of the container stick together.

    other as the tank empties. By partially emptying the container, the needle 19 can be removed, and the valve 5, due to the properties of the material from which it is filled, closes again, which eliminates the possibility of fluid outflow from the container and penetration of contaminants inside the surrounding atmosphere. Central surfaces 15 having a conical shape are made on said surfaces. The container can also be welded by longitudinal seams 16 and 17 in the case of its manufacture from a non-tubular film. The container may have holes 18 for stitching it on the hooks. Elastomer valve 5 is made directly by pressing a mixture of butyl and natural KayiyKOB (from 10 to 40%, preferably about 15% natural rubber), which provides good mechanical characteristics and permeability for the needle of the emptying device. The valve 5 has a protrusion. the edges 13 prevents them from sticking together in the store where they are placed in the foot, and from where they are fed automatically to the tank manufacturing line. The recesses 14 limit the penetration of air into the space formed between the upper and lower surfaces of the valve 5 and the corresponding plastic coatings in the manufacture of the valve itself. The elastic valve 5 is welded to one of two sheets of three-layer plastic, which are then welded in the longitudinal and transverse directions with the formation of seams 16,17 and 2 to obtain an elastic container, open at one end, through which the liquid is introduced. Then, the open end of the filled container is welded to form a transverse seam 3. If it is necessary to remove the liquid placed in the container, the valve 5 is pierced with a needle 19 of the emptying device (not shown) from the bottom of the three-layer plastic plate, as well as the supply valve 5 with the indicated coatings containing a special combination of materials prevents the formation of decomposition products and ensures complete sterility of the liquid placed in the container. soft, flexible, and valve material permeable to the needle. Claim 1. Flat elastic container for sterile fluid content, extracted under absolutely sterile conditions, comprising a housing, the walls of which are welded at least from two sides to form a cavity for receiving and containing fluid, and an elastomer valve welded to the housing , in order to provide access to the fluid placed inside the tank, it is necessary to ensure that, in order to prevent contamination of the fluid by decomposition products, the walls of the housing are made of three-layer plastic, including yuchuyu outer layer containing propylene polymer, the inner layer containing a copolymer of ethylene and butylene in the amount of 9099% and 1-10%, respectively, and an intermediate layer of amide polymer, one of the valve surfaces is covered with 16 indicated three-layer plastic, and the other surface is covered with two-layer plastic, including the first layer of copolymer of ethylene and butylene in the amount of 90-99% and 1-10%, respectively, and the second layer of amide polymer, and these layers of two-layer and three-layer plastics are welded with each other .
