Description

The invention relates to the bottling of liquid products, in particular to filling devices used in the medical, pharmacological, biological, food, and other industries, providing packing, container tightness control, as well as filling containers, liquid products and emptying it under aseptic conditions under vacuum. A device for sterile filling of containers is known, consisting of a body with fittings for supplying and removing fluid and air and a centering opening for the neck of the container, and mounted in the body with the possibility of vertical movement of the overflow tube and the mechanism for opening and sealing the container {l . However, the known device does not guarantee the guaranteed isolation of the product from contact with the external environment in the process of filling. The aim of the invention is to improve the tightness of the connection of the device with the container and the ISOLATE, thereby, the product from contact with the external environment. The goal is achieved by the fact that the overflow tube and the mechanism for opening and closing the containers are equipped with elaotic membranes fixed at their connection to the case, and the mechanism for opening and sealing of the container is made in the form of a rotary lever having a plug fixed to the stem on the stem. parallel to the axis of the overflow tube. Along with this, the body is made of transparent material. FIG. 1 shows a device for sterile filling of a container; general view; in fig. 2 - the position of opening and closing the city stopper of the container with a stopper; in fig. 3 - the position of the overflow tube during filling and emptying the container. The device for sterile filling of the container includes a housing 1 made of a transparent material, with lids 2 and 3. In spring 2, a centering 4 is mounted from 745866 to connect the container neck 5, sealed with a stopper 6 and with a siphon tube 7, channels 8 for air removal and sealing spacer 9. Along the axis of the hole 4 in the housing 10 is installed & Lena overflow tube 11, which is with the stem of the neu-cylinder 12, which ensures its vertical movement. The device additionally contains a mechanism for opening and closing the container, executed in the form of a pivoting lever 13, having a plug 15 on the shank 14, designed to close the opening 16 of the overflow pipe 11, the pivoting lever 13 is fixed on the rod 17 of pneumatic cylinders 18 and 19 located parallel to the axis and overflow tube. The inlets into the housing 1 of the overflow tube 11 and the stem 17 are sealed with elastic membranes 2O and 21. In the clamp 2, a fitting 22 is installed for supplying the test liquid and a sterilizing substance, in the cover 3 a shield 23 is provided for supplying and removing air. The overflow tube 11 in its upper part has a fitting 24 for feeding and removing the product. The device works as follows. ------ - - - .. .- .; -:: The neck 5 of the container (see FIG. 2) is sealed with a stopper 6, is introduced into the centering opening 4 of the lid 2 and pressed against it with a sealing gasket 9. In kqpnyce 1, the control liquid is supplied to the level somewhat higher than the upper throat plane through the clamp 22 of the bracket 2. (guilt 5, the cavity of the chamber is evacuated and the tightness of the joint is monitored using the puzy method. Then the control liquid is removed through the die 22, and the internal cavity of the housing 1 is sterilized with the supply and removal of the sterilizing agent. th agent, displaced air, fills; the cavity of the separation chamber and the cavity of pipelines connected to it. The overflow tube 11 rises, the portal lever 13 rotates clockwise, goes down, noBq turns counterclockwise; rises up, removes it from the reservoir. 5 tars and returns to its original position. Overflow tube 11 is lowered to dock with siphon tube 7, creating an isolated overflow path (Fig. 3) After which the cavity to the device fpus 1 and the container are evacuated, and the air is removed through the air exhaust ducts 8 and the shroud 23 of the lid 3 and the product from the dispenser is poured into the container through the overflow pipe & vacuum supply of air through the filter system, after which the overflow tube 11 rises upwards (Fig. 2), the lever 13, turning and lowering, closes, with the stopper 6, the neck 5 of the container. Then, the lever 13, turning, releases the plug 6, rises upward, turns clockwise, and the overflow tube 11 goes downward until it is connected by its seal with the plug of the fork plug 14. The control liquid is supplied to the housing 1 through the fitting 22 to a level above the upper plane of the neck 5 and to the sealing plate of the overflow pipe 11. The cavity of the housing 1 is evacuated and the tightness of the container neck closure and closure of the overflow pipe is made. After that, the control liquid is removed and the internal Kqpnyca 1 vacuum is evacuated and the tightness of the throat packing and the overflow tube is closed by means of a bubble method. After that, the liquid is removed and the internal cavity of the housing 1 is sterilized, throat 5, lower, detach -. comes from the device. When emptying the junction, opening and closing of the harping junction, monitoring the tightness of the junction and capping, the closure of the overflow tube cavity is performed in the same way as in the filling operation. .. -.,. J After creating an isolated overflow path of the chamber cavity and the container, communicate with the atmosphere through the filter system, the cavity of the overflow tube is evacuated and the container is removed from the product in a siphon manner. As a result of such device enhancement, the tightness of the connection between the device and the container and thus the isolation of the product from contact with the external medium is increased. The formula of the invention. A device for sterile filling of containers, consisting of a body with fittings for supplying and removing liquid and air.

and centering aperture of the container neck, and mounted in the housing with the possibility of vertical movement of the overflow pipe and mehaiism for opening and sealing the container, which is different in order to increase the tightness of the device with the container and insulate, thereby, product from contact with the external environment, the overflow tube and the mechanism for opening and sealing of the container Yu are provided with elastic membranes fixed at the points of their connection with the box.

the mechanism, and the mechanism for opening and sealing of the container is made in the form of a pivoting lever having a stopper on the shank and fixed on the rod parallel to the axis of the overflow pipe.

2. The device according to claim 1, in connection with the fact that Kqpnyc is made of 1 transparent material.
