    A one-piece plastics closure for a carbonated beverage bottle has a sealing ring (17) pivotally attached at the junction between its closure panel (10) and dependent skirt (11). The sealing ring is forked, having two annular and mutually divergent fins 20, 21. The upper fin (20) is engaged by the free end of the container neck as the closure is fitted, and by pivotal movement of the sealing ring brings the lower fin (21) into sealing relation with the side surface of the container finish. The resilience of the closure material and the substantial deformation to which the sealing ring is subject thereafter maintain the effectiveness of the seal despite creep and backing-off of the closure which may occur.

    This invention relates to a solid plastic cap for a container with a monolithically molded sealing element,
    The purpose of the invention is to improve the tightness.
    Fig, 1 shows the roof, section; in fig. 2 - treads while putting it on the bottle neck; on fig.Z - the same on. a later stage of putting it on the throat of the cap; FIG. 4 - krpak, put on the bottle neck.
    The one-piece plastic cap for the container consists of a cylindrical body 1 closed at one end by means of the bottom 2 fixed at the point where the latter connects to the cylinder of the annular sealing element 3 including two lobes 4 and 5 and the annular neck 6 and formed on the inner surface of the bottom the annular protrusion 7 to press one of the petals to the neck of the container 8 (bottle). Petals 4 and 5 on the sealing element 3 diverge from the neck 6 to press, respectively, against the upper and side surfaces of the neck of the container 8. The upper lobe 4 has the shape of a truncated cone and a cylindrical free edge 9.
    The lower lobe has parallel sides and a cylindrical shape; it ends with an annular free edge 10; the conic surface of the petal 4 faces the lower surface of the bottom 2 of the lip 9 of the annular protrusion 7.
    The cylindrical outer surface of the petal 5 faces toward the bead 11. On the inside of the bead 11 there is a screw thread 12 for contacting with the screw thread 13 of the bottle neck. The sealing element 3 has a concave vaulted lower surface 14 formed between the petals 4 and 5.
    The cap is screwed to the neck of the bottle as follows.
    When the cap is screwed onto the neck of the bottle and the lower corner of the upper petal 4 is pressed against the annular top surface 15 of the bottle neck, the sealing element is not bent at this time and is in the position in which it is cast (Fig. 2).
    Upon further tightening of the lid, the sealing element 3 is rotated counterclockwise relative to the neck 6 (which serves as a one-piece hinge), while the upper lobe is simultaneously held back and cannot move along the surface 15 radially inward.
    The rotation of the sealing element 3, together with the relative upward movement of the container neck, gradually leads to the contacting of the inner lower angle of the lower lobe 5 with the bottle neck on the cylindrical lateral surface 16 of the container neck and cap (FIG.). After this, only a slight inclination of the sealing element 3 occurs or there is no inclination at all, but the contact surface between the surfaces 17 and 16 increases more and more as the lid is turned down and the surface 17 moves over the surface 16. The lid continues to roll until it reaches the corresponding position (figure 4). In this position, the upper lobe 4 presses against the annular protrusion 7 and tightly presses this protrusion against the free upper surface 15 of the container. The protrusion 7 is a stop fixing the key in the wrapped position of the scientific research institute.
    The configuration of the sealing element and the container neck with their relative movement is such that as they are screwed down, the petals 4 and 5 become more and more bent and curved in accordance with the respective surfaces of the container neck, in particular the upper lobe 4 flattens to such an extent that flat contact with the neck is created capacity. An upward force acting on the upper lobe 4 from the bottle side is transmitted to the lower lobe 5 by the body 18, as a result of which an inwardly directed horizontal force arises that presses the lower lobe against the side surface 16 of the container. In order to ensure effective transfer of force between the ribs with low attenuation, the lid body 1 is made rigid and the neck 6 is narrow and therefore flexible as the casting technology allows.
    In the screwed-up state, the force force and the contact area between the surfaces 16 and 17 are large and between these surfaces provides effective sealing for gases and liquids (Fig. E). In addition, the residual stresses and the strong distortion of the sealing element and the elasticity of the plastic from which it is made ensure the integrity of the plastic, despite the creep and lagging of the plastic krishki, which may occur until the bottle is opened by the consumer.
    In addition to lateral sealing between surfaces 16 and 17, additional sealing is formed between the bottom surface 19 of upper lobe A and the surface of the bottle 15. This seal provides an additional guarantee of the tightness of the bottle. However, this seal is auxiliary due to its relative sensitivity and relaxation of the cover, while the side seal can be broken only with a large reverse rotation of the cover. The contact area of the upper seal is round (Fig. 4), and the upper lobe A is deformed by the pressure directed upwards from the side of the neck 8 of the bottle and pressure downward from the side of the protrusion 7.

    2, a dashed line 20 depicts the possible implementation of the upper lobe of circumferentially arranged segments. These segments do not allow the seal to be set up against the petals with the neck of the bottle, which allows gas to quickly escape, finding a plug in the bottle when the cap is unscrewed. The die is injection molded from a thermoplastic mixture, for example polypropylene, using a punch and die.
    Fore. Mule Invention
    1. One piece plastic tank for the container, which is a cylinder closed at one end
    using a bottom and an annular sealing element fixed at the point where the latter connects to the cylinder, which includes two petals, which means that in order to improve the tightness, the sealing element is reinforced by means of an annular neck with the possibility of its rotation relative to the sealing surface of the container.
    2. Cover POP.1, characterized in that an annular protrusion is formed on the inner surface of the cylinder bottom to press one of the petals to the neck of the container.
