The flexible element is connected to the lower part and the cap by film hinges integral with the lower part and the cap. The flexible element has a shape which is folded repeatedly and which is such that a straight line penetrating the flexible element intersects the flexible element at least at three points. The construction allows the design of plastic tops with a flat, cap having an extremely large angle of opening and a strong snap action.
I claim: 1. A single piece plastic snap hinge closure comprising: a lower part having a circumferential wall and a cap comprising a flat top surface part, said lower part and said cap being connected to each other by at least one film hinge defining a pivoting axis of said closure, said lower part forming a pouring spout opening; a flexible element generating a snap action, said film hinge situated on a line defined by an intersection of an outer surface of the circumferential wall and said flat top surface part of the cap when the closure is in a closed position; said flexible element connected to said lower part by a first flexible element film hinge integral with said outer surface of the circumferential wall and to said cap by a second flexible element film hinge integral with said flat top surface part of said cap; said flexible element comprising a plurality of partial sections forming a shape of an "S", said "S" shaped flexible element having two outermost legs being equal in size to each other and interconnected by a central portion, said legs of said "S" shaped flexible element being one of perpendicular and parallel to said outer surface of said circumferential wall in an open position of said closure and being the other of perpendicular and parallel to said outer surface of said circumferential wall in said closed position of said closure; and said flexible element in the open position of said closure disposed as much outside a shape defined by said circumferential wall and said flat top surface of said cap as it is inside said shape int he closed position of said closure.
2. A single piece plastic closure in accordance with claim 1, wherein an upper leg of said "S"-shaped flexible element is flush with said flat cover of said cap in a completely closed position of the closure.
DESCRIPTION OF PREFERRED EMBODIMENTS A plastic top is shown in FIGS. 1 to 5, which is suitable for use with a plastic container 30 having only a small pouring spout 31. Such containers are particularly used in connection with cosmetics which are applied directly to the skin, such as suntan lotions or body lotions. This requires that a cap 2 of the top can be rotated about at least 180
The hinge 42 connects the cap 2 to the flexible element 4. As shown most distinctly in FIG. 4, the two flexible element hinges 41 and 42 are at the same distance from the fixed film hinge 3. In such arrangement, the minimal distance between the two flexible element hinges 41 and 42 is a hinge 3 is equal to "a". In the unstable equilibrium position, such as shown in FIG. 3, the maximum distance between the two hinges 41 and 42 is attained and is exactly 2 41, 42 are located vertically on top of each other.
A further embodiment of the invention is shown in FIGS. 6 and 7, and has a second top. It essentially has the same characteristics as the previously described top illustrated in FIGS. 1 to 5. However, the top of FIGS. 6 and 7 is suited for use with a container 30', shown in dashed lines, with a container neck 32. Accordingly, the lower part 1 must be designed in such a way that it can enclose the container neck 32. For this purpose, the side wall 10 of the lower part 1 abutting against the container 30' has a cover 14 with a vertically downward directed annular wall 15, which surrounds and seals the container neck 32 of the container 30'. A spout 16 has been formed in the cover 14 of the lower part 1 within the area defined by the annular wall 15. It is closed by a tang 21 formed on the cover 20 of the cap 2. In this case, the seal is not made between the container and the cap 2 but, as is customary with plastic tops, between the lower part 1 and the cap 2. Of course, the cover 14 of the lower part 1 does not permit a unified manufacture of the top. It is injection-molded in the completely open position, as shown in FIG. 7. This is possible because the flexible element 4 can be positioned in such a way that it can be ejected from a mold even in the completely open position of the top. The opening 40, visible from the outside in the closed position of the top, is now located in the side wall 10 of the lower part 1. However, in the completely open position of the top the flexible element 4 is flipped outward by 90 vertically downward and thus parallel to the side wall 10 and in the extraction direction of the injection mold.
