SU302888A1 - CAP OF ELASTIC MATERIAL - Google Patents

Description

FIELD OF THE INVENTION The invention relates to the food industry, namely to the technique of sealing glass bottles containing both quiet and carbonated liquids.

Known cap of elastic material, such as polyethylene, made in the form of a closed cylinder on one side with a tongue on its outer surface. Inside the cap is arranged nozzles, the inner surface of which is corrugated.

The purpose of the invention is to increase the tightness of sealing bottles with carbonated liquids.

This is achieved by the fact that the conical nozzle is fixed on the inner surface of the cylinder so that when it closes it enters the groove on the neck of the bottle.

FIG. 1 shows the proposed cap, in section; in fig. 2 and 3 - the stage of putting the cap on the bottle.

The cap is a cylinder 1, closed on one side by a cap 2, a tongue 3 and nozzles 4, made as one piece. The nozzles 4 have corrugations 5 on their lower surface. The inner diameter of the nozzle 4 is smaller than the inner diameter of the cylinder 1. Outside, the cap may have a metal coating 6, manufactured together with the cap.

The bottle 7 with the liquid to be capped has an annular groove 9 below the upper edge 8. A cavity 10 is formed between the inside diameter of the cylinder / and the nozzle 4.

The cap is placed on the upper edge 8 of the bottle 7 and pressed vertically down. When moving down under the action of this pressure, the nozzles 4 are bent up first, and when they fall into the groove 9, it fills it, pressing the corrugations 5 against the groove. In this case, the nozzle creates a force that presses the lid 2 to the top edge 8 of the bottle.

If the pressure of the contents rises to such an extent that it penetrates between the lid 2 and the edge 8, then, once in the cavity 10, the contents press down the corrugations 5 to the groove 9, creating additional pressure to ensure the tightness of the closure.

Subject invention

A cap of elastic material, such as polyethylene, for closing bottles, made in the form of a cylinder closed on one side with a tongue on the outer surface and located inside its conical nozzle, the inner surface of which is made corrugated, characterized by that.

that, in order to increase the tightness of the closure of vessels with carbonated liquids, the conical nozzles are fastened on the inner surface of the cylinder so that when flipping it enters the groove on the neck of the 6v taps.
