DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(34) According to the first embodiment of the invention presented in FIG. 1 to FIG. 18, a mechanism for opening and reclosing the outflow opening 2 for emptying a container incorporates a latch 6 for opening and reclosing the said outflow opening 2 in the lid 1 of the container. The latch 6 is fitted with a single pair of hatching elements 7, and the lid 1 features a single pair of sliding elements 3 formed on the side longitudinal walls of the opening 2 (as shown in FIG. 3), or on the top surface of the lid 1 along the top longitudinal edges of the opening 2 (not shown on the drawing). The pair of the hatching elements 7 is fitted slidingly on the said sliding surfaces 3, which serve as guides for the hatching element 7 when the latch 6 is in motion. The sliding surfaces 3 are parallel to each another and are given the shape of a convex arch, in addition they are formed so that their ends are positioned at different heights with respect to the bottom surface of the lid 1 around the opening 2, where the ends 3a from which the movement of the latch 6 starts towards the opening of the outflow opening 2 are positioned higher than their other ends 3b, i.e. at a slope down in the direction in which the latch 6 moves towards the open position. When in the closed position, the latch 6 contacts the bottom surface of the lid 1 around the opening 2, as shown in FIG. 9, FIG. 11, and FIG. 13, and when in the open position, it is distant from the bottom surface of the lid 1, as sown in FIG. 10, FIG. 12, and FIG. 14.

(35) Formed on the bottom surface of the lid 1 are longitudinal ribs 4, where positioned in between the ribs is the end part of the latch 6a, so that between the lid 1 and the end part of the latch 6, in between the said ribs 4, formed is a slit 10 to supply air to the container during its emptying, as shown in FIG. 10.
Formed on the bottom surface of the lid 1 is a pair of longitudinal distancing elements 5 extending from the longitudinal ribs 4, and formed on the bottom surface of the latch 6 is a pair of transverse distancing elements 9 which cooperate with the said longitudinal pair of the distancing elements 5 of the lid 1.
Moreover, formed on the top surface of the latch is an element 8 for initiating movement of the latch, as shown in FIG. 1, and the latch can be fitted with an additional sealing and actuating tongue 11 with an gripping rib 11a formed thereon for setting the latch in motion, where the tongue 11a is fitted on the said element 8, as shown in FIG. 15 and FIG. 16; optionally, the latch can be fitted with an additional rotating sealing and actuating cap 12 with an gripping rib 12a formed thereon for setting the latch in motion, cooperating with the said element 8 of the latch. Moreover, the said rotating cap 12 features an opening 13 for emptying the container, and an opening 14 for supplying air to the slit 10 when emptying the container, as shown in FIG. 17 and FIG. 18.

(36) In the second exemplary embodiment of the invention, presented in FIG. 19 to FIG. 32, the mechanism incorporates the latch 106 for the opening and reclosing of the said outflow opening 102 in the lid 101 of the container. The latch 106 is fitted with two pairs of hatching elements 107 (as shown in FIG. 20), and the lid 101 features two pairs of sliding surfaces 103 formed on the side longitudinal walls of the opening 102, serving as the guides for the hatching elements 107 when the latch 106 is in motion. The sliding surfaces 103 of each specific pair are positioned parallel to each another, and the pairs of the sliding surfaces 103 are positioned one pair after another in the direction of movement of the latch 106, as shown in FIG. 21. Moreover, the sliding surfaces 103 in each pair are formed of two convex arched sections 103 103 of different radiuses, as shown in FIG. 21. Ends of the arched surfaces 103 of each pair are positioned at different heights with respect to the bottom surface of the lid 101 around the opening 102, where the ends of the pair of the arched surfaces 103a from which the movement of the latch starts towards the opening of the outflow opening are positioned higher than the other ends 103b of the specific pair, i.e. at a slope down in the direction in which the latch 106 moves towards the open position, and where the end of the arched surface of each arched section 103, 103 from which the movement of the latch 102 starts towards the opening of the outflow opening 102 is positioned higher than its other end, i.e. at a slope down in the direction in which the latch 106 moves to the open position. In each pair of the sliding surfaces 103 the arched sections 103 from which the movement of the latch 106 starts towards the opening of the outflow opening 102 are shorter than that of the immediately following arched sections 103, and the radius of the arched sections 103 from which the movement of the latch 106 starts towards the opening of the outflow opening 102 is smaller than the radius of the curve of the immediately following arched sections 103.

(37) Each pair of the hatching elements 107 is fitted slidingly on a single pair of the said sliding surfaces 103 which serve as guides for these hatching elements 107 when the latch is in motion, as shown in FIG. 23 and FIG. 25. One pair of the hatching elements 107 cooperates with one pair of the sliding surfaces 103.
In the closed position, the latch 106 touches on the bottom surface of the lid 101 around the opening, as shown in FIG. 27, and in the open position it is distant from the bottom surface of the lid 101, as shown in FIG. 28.
Formed on the bottom surface of the lid 101 are longitudinal ribs 104, positioned in between which is the end part 106a of the latch 106, so that formed between the lid 101 and the end part 106a of the latch 106, and between the said ribs 104 is a slit 110 to supply air into the container during its emptying, as shown in FIG. 28. Formed on the bottom surface of the lid 101 is a pair of longitudinal distancing elements 105, and formed on the bottom surface of the latch 106 are two transverse distancing elements 109 which cooperate with the said pair of the distancing elements 105 of the lid 101. In addition, formed on the top surface of the latch 106 is an element 108 in the form of a gripping rib for initiating movement of the latch.

(38) In the invention embodiments described above, the container, lid, and mechanism are all made of the same plastic.

(39) When the opening 2, 102 is being opened, the latch 6, 106 moves downwards, towards the inside of the container. When the movement of the latch 6, 106 towards the opening of the outflow opening 2, 102 is initiated, the latch gets immediately moved downwards, towards the inside of the container thanks to the arched shapes of the sliding surfaces 3, 103 which cooperate with the hatching elements 7, 107, and the slit 10, 110 through which air is supplied into the container opens up to the opening 2, 102. Further shifting of the latch 6, 106 towards the opening of the outflow opening 2, 102 causes further downward movement of the latch 6, 106 and increases the distance between the top surface of the latch 6, 106 and the bottom surface of the lid 1, 101 around the opening. The flow of air into the container through the slit 10, 110 ensures laminar flow of beverage out of the container. The shaping of the sliding surfaces 103 into two arched sections 103 and 103 makes it possible to reclose the opening 102 tightly. The first shorter arched section 103 of the sliding surfaces 103, the radius of which is smaller than that of the second section 103, ensures immediate downward movement of the latch 106 during the opening of the outflow opening 102 and distancing the top surface of the latch 106 from the bottom surface of the lid 101.

(40) The mutually cooperating distancing elements of the lid and the latch stabilise the movement of the latch during opening and reclosing of the outflow opening.
