Description
Plastic Snap Binge With A Flexible Element Generating The Snap Action This invention relates to a single piece plastic closure with a snap hinge having two parts connected by at least one hinge, and a flexible element generating the snap action, which is hingedl.y connected to the two parts of the closure.
Plastic snap hinges for closures can be roughly classified into two types, namely those where the snap effect is generated by a. tension element and those where it is generated by an elastically flexible element. This invention relates to a closure with a plastic snap hinge of the second type.
Conventional elastically flexible elements have a shape in the form of a letter "U" or "L", as, for example, is known from U.S. Pat. No. 4,911,324 or U.S. Pat. No.
Plastic snap hinges for closures can be roughly classified into two types, namely those where the snap effect is generated by a. tension element and those where it is generated by an elastically flexible element. This invention relates to a closure with a plastic snap hinge of the second type.
Conventional elastically flexible elements have a shape in the form of a letter "U" or "L", as, for example, is known from U.S. Pat. No. 4,911,324 or U.S. Pat. No.
2,630,239. The size of the elements is essentially determined by the spring path and the desired spring force.
However, particularly .in connection with the use of plastic tops, other marginal conditions which greatly affect the geometry of a plastic snap hinge are opposed to this.
Conventional flexible elements cannot be used, particularly when employing tops with relatively large pouring spouts and a relatively f:Lat lid. In the case of an L-shaped flexible element, -the leg extending through the cover of the lid cannot be made sufficiently long, because otherwise it would extend in~~o the sealing area of the pouring spout.
A U-shaped flexib:Le element cannot be made sufficiently large, because the low :height of the lid does not provide enough space to accept the flexible element.
Such a hinge has its most relaxed position when the corrugated hinge strips are at least curved. This condition occurs in a position between opened and closed.
Another solution is taught by U.S. Pat. No. 3,629,901 where the elastically f:Lexible element is parted in two sections of U-shape form as corrugated hinge strips, while an intermediate inflexible section remains.
It is one object of this invention to provide a flexible element which can be used in connection with plastic hinges which is fully integrated into the form of a single piece plastic closure having a flat top cover part and a lower part with a circumferential wall being vertical to the flat top cover in the area of the hinge.
Accordingly, the present invention relates to a single-piece plastic snap-hinge closure comprising a lower part, a cap, and a flexible element. The lower part forms a pouring spout opening and has a circumferential wall.
The cap comprises a flat top surface part. The lower part and the cap are connected to each other by film hinge means defining a pivoting axis of the closure. The film hinge means is situated on a line defined by an intersection of an outer surface of the circumferential wall and the flat top surface part of the cap when the closure is in a closed position. The fle:Kible element generates a snap action.
The flexible element is connected to the lower part by a first flexible element film hinge integral with the outer surface of the circumfe:rential wall, and connected to the cap by a second flexible element film hinge integral with the flat top surface part of the cap. The flexible element comprises a plurality of partial sections forming a shape of an "S". The "S"-shaped flexible element having two outermost legs equal in size to each other and interconnected by a central portion. The legs of the "S"-shaped flexible element are one of perpendicular and parallel to the outer surface of the circumferential wall in an open position of t:he closure and are the other of perpendicular and parallel to the outer surface of the circumferential wall in the closed position of the closure.
The flexible element in the open position of the closure is disposed as much outside a shape defined by the circumferential wall and. the flat top surface of the cap as it is inside the shape in the closed position of the closure.
A significant benefit of the hinge construction in accordance with this invention is that it provides better flexibility than known hinge constructions thus permitting closures with thinner walls to save plastic material and reduce costs.
Further embodiments in accordance with the invention and their purpose will be explained in the description below.

Further embodiments in accordance with the invention and their purpose will be explained in the description below.
Two preferred embodiments of this invention are illustrated in the drawings and will be explained in the following description, wherein:
FIG. 1 is a perspective view of a plastic top and the snap hinge in accordance with one embodiment of this invention;
FIG. 2 is a longitudinal section of the flexible element of the top, as shown in FIG. 1, in a closed position;
FIG. 3 is a view of= the flexible element shown in FIG.
2, in a half-opened position;
FIG. 4 is a view of the flexible element shown in FIG.
2, in a fully open position;
FIG. 5 is a cross-sectional view, crosswise to the previously illustrated sectional planes of the top in accordance with FIG. 1, placed on a container;
FIG. 6 is a cross-sectional view, of another embodiment of the :plastic top with a differently positioned flexible element, in a closed position; and FIG. 7 is a cross-sectional view in accordance with FIG. 6, with the f:Lexible element in a completely open position.
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°, with respect to a closed position of the top.
The top comprises a lower part 1 and the cap 2, which are pivotally connected with each other with two film hinges 3 positioned in a straight line. A flexible element 4 is positioned between the two film hinges 3 and generates a spring force nec:essar:y for the snap action.
The lower pant 1 comprises an annular, circumferential wall 10 having a c:onica:Lly tapering collar 11. The pouring spout 31 of the containE~r 30 is disposed within the lower part 1 of the clo:>ure. A gap 12 remains between the cap 2 and the lower part: 1, even in the closed position. This is required so as to make it possible to injection-mold the top in the closed position. The collar 11 of the lower part 1 is depressed in an area opposite the film hinge 3 to form a recess 13 which makes it possible to push the cap 2 upwards with a thumb, beyond the unstable equilibrium position, after which the cap snaps into a completely opened position, as shown in FIG. 4.
Sealing the cap 2 with the pouring spout 31 of the container 30 is accomplished with a sealing tang 21, injection-molded to the underside of the cover 20. To enhance the seal and i:n particular the closing strength, the tang 21 may have at least one circular seal ring 22.
For reasons of appearance as well as for increasing the stiffness, the cover 20 in accordance with this embodiment of the invention is formed upwardly concave in this case.
A plurality of support cams 23 may be provided on the underside of the cover 20, for defining the relative position of the cap 2 with respect to the container 30. In the assembled stage of 'the top and closed position of the cap 2, the support: tangs 23 rest on the container 30.
In this embodiment, the flexible element 4 can also be ejected from a mo:_d in the closed position of the top. In cross section, the flexible element 4 has the shape of the letter "U" and of a fal:Lowing, upside-down letter "L". The opening 40 of the U-shaped part extends exactly in the extraction direction of the mold tool. The flexible element 4 is connected with the cap 2 and the lower part 1 with two flexible element hinges 41 and 42 integral with circumferential wall 10 of lower part 1 and the flat top of cap 2. The hinge 41 forms the connection between the circumferential well 10 and the flexible element 4 and is located approximately at: the level of the upper edge of the container 30, on ~rhich t:he top has been mounted.
The hinge 42 connects the cap 2 to the flexible element 4. As shown mo~~t 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~~, if the distance from each hinge 41, 42 to the film 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~a. This is. the case when the two hinges 41, 42 are located vertically on top of each other.
FIG. 1 is a perspective view of a plastic top and the snap hinge in accordance with one embodiment of this invention;
FIG. 2 is a longitudinal section of the flexible element of the top, as shown in FIG. 1, in a closed position;
FIG. 3 is a view of= the flexible element shown in FIG.
2, in a half-opened position;
FIG. 4 is a view of the flexible element shown in FIG.
2, in a fully open position;
FIG. 5 is a cross-sectional view, crosswise to the previously illustrated sectional planes of the top in accordance with FIG. 1, placed on a container;
FIG. 6 is a cross-sectional view, of another embodiment of the :plastic top with a differently positioned flexible element, in a closed position; and FIG. 7 is a cross-sectional view in accordance with FIG. 6, with the f:Lexible element in a completely open position.
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°, with respect to a closed position of the top.
The top comprises a lower part 1 and the cap 2, which are pivotally connected with each other with two film hinges 3 positioned in a straight line. A flexible element 4 is positioned between the two film hinges 3 and generates a spring force nec:essar:y for the snap action.
The lower pant 1 comprises an annular, circumferential wall 10 having a c:onica:Lly tapering collar 11. The pouring spout 31 of the containE~r 30 is disposed within the lower part 1 of the clo:>ure. A gap 12 remains between the cap 2 and the lower part: 1, even in the closed position. This is required so as to make it possible to injection-mold the top in the closed position. The collar 11 of the lower part 1 is depressed in an area opposite the film hinge 3 to form a recess 13 which makes it possible to push the cap 2 upwards with a thumb, beyond the unstable equilibrium position, after which the cap snaps into a completely opened position, as shown in FIG. 4.
Sealing the cap 2 with the pouring spout 31 of the container 30 is accomplished with a sealing tang 21, injection-molded to the underside of the cover 20. To enhance the seal and i:n particular the closing strength, the tang 21 may have at least one circular seal ring 22.
For reasons of appearance as well as for increasing the stiffness, the cover 20 in accordance with this embodiment of the invention is formed upwardly concave in this case.
A plurality of support cams 23 may be provided on the underside of the cover 20, for defining the relative position of the cap 2 with respect to the container 30. In the assembled stage of 'the top and closed position of the cap 2, the support: tangs 23 rest on the container 30.
In this embodiment, the flexible element 4 can also be ejected from a mo:_d in the closed position of the top. In cross section, the flexible element 4 has the shape of the letter "U" and of a fal:Lowing, upside-down letter "L". The opening 40 of the U-shaped part extends exactly in the extraction direction of the mold tool. The flexible element 4 is connected with the cap 2 and the lower part 1 with two flexible element hinges 41 and 42 integral with circumferential wall 10 of lower part 1 and the flat top of cap 2. The hinge 41 forms the connection between the circumferential well 10 and the flexible element 4 and is located approximately at: the level of the upper edge of the container 30, on ~rhich t:he top has been mounted.
The hinge 42 connects the cap 2 to the flexible element 4. As shown mo~~t 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~~, if the distance from each hinge 41, 42 to the film 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~a. This is. the case when the two hinges 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. l.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 contaner 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 waJ_1 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 t:he container and the cap 2 but, as is customary with plastic i:ops, between the lower part 1 and the cap 2. Of course, l.he cover 14 of the lower part 1 does not permit a unifiE~d manufacture of the top. It is injection-molded i.n the completely open position, as shown in FIG. 7. This i.s pos;~ible because the flexible element 4 can be positioned in such a way that it can be ejected from a mold even in they 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°
around the hinge 91. Now the opening 40 extends vertically downward and thus parallel to the side wall 10 and in the extraction direct_Lon of the injection mold.
In this embodiment, too, the same geometry of the flexible element has been used, as the embodiment shown in FIGS. 1 to 5. Although only one general shape, and most likely the one used mast often, has been illustrated, such important aspect of this invention can be expressed more generally, and it is of course obvious, that the partial sections of the flexible element 4 need not necessarily extend parallel. Thus, instead of a U-shaped part there can be a V-shaped part. Also, the partial sections which in this case are ~>traight, can be arched. In principle, it is only necessary that l.he flexible element 4 be designed accordion-like, so that it is always possible to extend a straight section which penetrates the flexible element at three different points. Only those flexible elements which meet this geometric definition provides an accordion-like shape, which allows great expansion in a small space and provides a large force f=or the snap effect.
