Description

COMPOSITIONABLE CLOSURE FOR ESPECIALLY PACKAGING CANS

The present invention relates to an assemblable closure for, in particular, shaker cans, which is described in the introduction of claim 1 is outlined in more detail.

Closures of this type which have become known so far show one Number of disadvantages, especially seen in combination. So it is often difficult and expensive to install the closures to be attached to a container provided for this purpose, which usually requires special fasteners, such as glue and / or special grooves for receiving, for example, the upper, free edge of a container. Another difficulty is that the closures of this type should usually be able to be opened and closed again, which means that at least two parts must be movable in relation to each other. All of this creates great difficulties, since in most cases the closures have to be attached after the goods to be closed have been entered. The discharge of goods is also often difficult of some kind tied together. The composition of the parts mentioned, which are movable in relation to one another, also causes difficulties, both in terms of manufacture and in terms of assembly and in terms of application.

The object of the invention is to provide the aforementioned Counteract disadvantages and eliminate them as far as possible. It is also the responsibility of the invention to update the state the technology in this field to continue in the most diverse ways and a generally advantageous

To create a closure that is light, simple and inexpensive to manufacture, at the same time as being simple and secure in the application is, but especially an easy and enables quick assembly, with a container carrying such a closure with a container to be dispensed Well cannot be adversely affected by the closure. According to the invention, these tasks are thereby achieved solved that a closure of the type mentioned in the is essentially as specified in the characterizing parts of claim.

Further features and advantages of the invention are evident following description with reference to the accompanying drawings. In these non-limiting exemplary embodiments are shown. Show it:

FIG. 1 shows a diametrical longitudinal section through a preferred closure according to the invention for, in particular, shaker cans, Figure 2 shows an enlarged section of the upper left

Part in Figure 1, FIG. 3 shows a section corresponding to FIG. 2

slightly modified embodiment, Figure 4 is a plan view of the lid of a closure according to Figure 1 or 2,

FIG. 5 shows a side view of the lid of a closure according to the invention according to FIG. 1 or 2 and FIG. 6 shows a top view of a closure according to FIG

In Figures 1 and 2, 1 designates a closure according to the invention, which in a slightly modified form in Figure 3 and 4 bears the reference number 2. These closures are for closing a container 3 that is open at the top provided, which is preferably a cylindrical box made of cardboard and / or plastic or metal acts. Such a container is closed by a base from which a cylindrical wall stands out. The closure according to the invention is consequently the counterpart to the base 4.

The closure according to Figure 1 and 2 shows a lower part 6, which is referred to in the alternative embodiment according to ^r igur and 4 by 7. Both lower parts are provided for cooperation with uniform covers 8. Each lower part 6 or 7 has a cylindrical wall 9, the diametrical outer diameter of which is approximately equal to the diametrical inner diameter of the container wall 5, so that each lower part can be pushed a little into the container 5 with its wall 9. This single-disk movement is finally inhibited by an annular circumferential support 10 which protrudes from the wall 9 in order, according to the embodiment shown in FIGS for introducing the upper area of the container wall 5 is present. According to the exemplary embodiment shown in FIGS. 3 and 4, the support 10 ends essentially in the area of the outside of the container wall 5, which may be the only difference between the two lower parts of the closure.

Both lower parts can be connected to the container by gluing and / or friction adhesion, i.e. a suitable fit, or in some other way.

The wall 9 showed one or more openings IZ, which are preferably closed by a temporary cover 13. This can be a special one Act thin wall area, which simply pierce or open when using the container is removed in another way »Of course, the opening 12, if it should be closed at all, can be also temporarily closed in other ways.

At its upper end, the wall 9 merges into an inner projection 14, which is preferably a circumferential short and inwardly projecting flange acts, which on the inside a slope 15 on

points, which converges towards the inside as a whole. The underside of this inner projection preferably forms one radially oriented annular locking bar

The cover 8 has a cover base 17, in the edge area of which there can be a circumferential elevation 18, which is known per se and serves an easy and safe stacking of containers by their The edges of the floor overlap the elevations and are thus largely secured against shifting and tilting.

The cover 8 overlaps with a side wall 19 the upper area of the lower part 6 or 7 and preferably extends down to the support 10. This cover side wall 19 has, for example, a large lid opening 20 and is spaced from it in the circumferential direction Small lid openings 21. By simply twisting the lid with respect to the container-fixed lower part the lower part opening 12 either close completely or coincide with one of the opening fields 20 and 21 bring.

Within the upper area of the lower part 6 or 7, an inner ring cover web protrudes from the cover base 17 downwards, with one of the slope 15 corresponding Sliding surface 23 is provided in the assembled state to rest against said slope. Opens out at the bottom the ring web 22 in an outwardly directed locking projection 24 from with an upper locking surface 25, the is provided to rest against the locking web 16.

Alternatively or in principle, discharge openings or symbols 26, 27, 28 can be provided on the outside of the lid base 17 or in the lid base. If it is a question of symbols, these are to be brought into agreement with a fixed index on the container in order to achieve a certain opening or closing position by turning the cover 8. If the openings are real, these can be next to

the openings 12, 20 may be provided or replace them. Under certain circumstances, the openings 26, 27, 28 can be temporarily close with self-adhesive tear-off flaps.

Such a closure is extremely light on one To attach the container 3, it is most advantageous if the lower part 6 or 7 initially without attached Lid is attached, what happens as already described by gluing and / or in a conventional way? can. The various work moments can advantageously be carried out automatically, since the requirements 10 the movement of bringing the container and the lower part together automatically set a certain limit.

As then the container provided with a lower part is completely open at the top, so that the goods to be filled can get into the container quickly and easily. The cover 8 is then simply pressed on, wherein the cover side wall 19 secure the slide-on movement controls until the projections 14 and 24 abut against each other, both and in particular the inner cover ring web be bent elastically to the side until finally the locking projection 24 the inner projection 14 is snapped and secured against removal, at the same time as, of course, a desired turning preferably endlessly possible. The lids can be opened practically in seconds or even within fractions a second and they can be stacked in a small space, with the elevation 18 not only serves to guide stacked containers, but also to a large extent to guide and secure mounting of lids stacked on top of one another, for example in magazines of a manufacturing and / or Fill line. The containers 3 are preferably designed and dimensioned in their bottom area in such a way that the with an all-round frame provided the The upper areas of the attached lower parts overlap, so that here, too, it is easy and safe to stack

and leadership is coming. Here, the embodiment according to Figure 3 and 4 can be advantageous because it does not
has parts protruding substantially beyond the wall 5, so that a tilting of containers provided with closure lower parts in, for example, magazines is practically impossible and it is possible to work safely with lower tolerances.

Embodiments described above and shown in the drawing figures are only intended to be non-limiting See examples that can be changed and supplemented as required within the scope of the inventive concept.
