Closure element made of plastic

The innovation relates to an organ of access Plastic, which is provided with a border, a bead, a hook or the like, provided vessel edge of a container, For example, a packaging container made of sheet metal, plastic or the like. Put on and by form · - and / or frictional engagement of the correspondingly shaped pelvis rim is held.

Such closure organs, also referred to as snap-on covers ¹¹ g ^ geJe, are known per se. They have the primary task is to hermetically seal example, in packaging containers the filling material to the outside, which is particularly important when it comes to goods with volatile aromatic constituents or hygroscopic properties. A closure of the type outlined above should also offer the possibility of being easily removed when the product is removed and just as easily put back on *. In most cases this is not the case, because the positive and / or frictional engagement ensures a good fit on the container, which also withstands external influences such as falling, bridging, etc., but is not easy to open. It is often difficult, for example, to create such closure organs without auxiliary means, for example one. To open a spoon handle or the like, and it takes a certain amount of force to put the snap-on lid back onto the packaging container in such a way that it resumes its hermetically sealed position.

It has also proven to be disadvantageous in such closure members that the lid has to be put aside after removal in order to empty the container, and in connection with this it often falls off or is even lost. _;

The object of the invention is to provide a remedy here. It is intended, therefore, a closure member of the type mentioned above are provided which ¹ makes it possible to remove contents from the container without the lid has to be removed completely. The requirement of the hermetic seal should still be "troll and effective". However, it should also continue to be guaranteed that a reclosing possibility is given without effort or expenditure of force.

The aforementioned object is achieved according to the innovation in that a part of the preferably horizontal cover surface with the mediation of a fiim hinge as vertical or hinged cover protruding at an angle to the bevel mirror is formed, the underside of which has a preferably vertical edge flange with a number of latching elements which, when the hinged cover is closed against the restoring force of the hinge in the sense of a Locking with corresponding latching elements that correspond to the inside of the opening area limiting circumferential inner collar are arranged. In such an embodiment according to the innovation of the closure organ is this' in a certain area Can be opened and locked, the film hinge serving as a swivel joint. The removal opening is designed in such a way that that the filling material can be removed, for example with a spoon or the like, without difficulty. By the upright Positioning the hinged lid prevents it from interfering with the removal of the product, e.g. in addition must be kept open. The cover itself can not be lost, come out of reach or the like., There it does not need to be removed as a whole from the container. Sr is in one piece and therefore relatively simple manufacturable.

It's simple and particularly advantageous for locking According to a further feature of the innovation, the embodiment consists in that the corresponding locking elements of the edge flange on the one hand and the inner collar on the other hand are interlocking cams. These are Easily included in the manufacturing process of the closing element and for keeping the hinged lid closed effective.

According to further features of the innovation, the film hinge and connected to it, the hinged cover either in the longitudinal extension or transversely to the longitudinal extension of the example rectangular or long oval basic shape exhibiting closure member be arranged. The appropriate design is based on the requirements of the relevant customers.

To make it easier to open the hinged cover, it has one on its circumference, preferably opposite the film hinge arranged flap-like handle.

Characterized in that, according to a further feature of the innovation, the free end of the circumferential inner collar a; on the end face of which has sealed-on film is more advantageous Provide an authenticity guarantee, which is required in many cases, which, as known to itself, before first removal of the product must be destroyed. As a result, the previously customary tamper-evident security in the form of a introduced inside the container and against the container opening edge glued, very precisely cut film avoided, which required a considerable amount of extra work in the production make the container necessary. Due to the renewal Design can be made on a precisely cut foil pieces are largely dispensed with «.

The innovation is based on an embodiment that is shown in the drawing, in the following explained in more detail:

With 1 is the body of the container in Figure 6 of the drawing, in the present case a packaging container made of sheet metal, designated, the upper end 2, in the present case Exemplary embodiment, merges into an inner hook. Instead of the inner hook, an outer hook, a per se known border, or if it is for example is a plastic packaging container, a bead may be provided.

The one designed as a hook in the present exemplary embodiment End 2 of the container .1, the rest of the arbitrary Cross-sectional shape, for example, round, but preferably rectangular or long-oval shape,

• is made up of an outer collar 3 and an inner edge 4 of the closure member 5 made of plastic such that a positive and / or frictional connection is given. As FIG. 6 clearly shows, the inner edge 4 has For this purpose, a step 4a, which lies under elastic deformation when touching down behind the trunk hook. The cover 5 is connected to the fuselage 1 through this connection virtually hermetically connected. The connection shown in the drawing between the closure member 5 and the body 1 is not the only possible one, rather it is conceivable, also other known hermetic positive and / or frictional locking Connections to be provided.

The preferably horizontal cover surface 6 of the closure member s 3 has, as shown in particular in FIGS. As can be seen in particular from FIG. 5, this cover 8 is connected to the film hinge 7 in the course of the manufacturing process of the entire closure member 5 in such a way that its position, which is perpendicular in the present case or at an angle to the cover surface 6, is its rest position.

By closing the cover 8 (see arrow direction in Figure 4) takes place against the restoring force of the hinge 7

The hinged cover 8 has, as shown in FIG. 4, clearly shows a vertical edge flange on its underside 9 j of a number distributed around the circumference Ra st elements 10 has. The opening area 11 is, starting from the cover mirror 6, by a circumferential Inner collar 12 limited, the also locking element

has elements I3, which correspond to those of the hinged cover 8 in the Versciilußstellung, the. So keep the hinged lid 8 in its closed position, the hasty cams 10, 13 having a holding force with one another that is greater. as the restoring force of the hinge it 7 · ■ ' As can be seen from FIG. 6, the latching cams I3 of the inner collar 12 in the present case have approximately hook-shaped shapes. The latching elements 10 of the cover 8 are designed accordingly and then also. Such a shape is not the only binding one, rather other shapes or designs of the locking elements 10, 13, for example as shown in dashed lines, can be provided, provided that the actual mutual interlocking purpose, which, however, must also ensure easy detachability, is fulfilled .

On its side opposite the film hinge 7 the hinged lid 8 has a handle l4 to facilitate opening & n of the lid 8. This handle l4 has in present case of lobular character. But she can also be designed differently, or, for example, additional grooves, small elevations on its surface or the like. For better detection.

As FIGS. 3 and 4 show, there is a front face of the inner collar 12 from the inside a film 16 as a guarantee closure or Origp.nali tat security sealed or welded. This foil 1-6 can consist of aluminum, one of which Side is covered with plastic. Because between the Inner collar 12 and the inner edge 4 of the locking device If there is still enough space available, the film 16 does not need to be given a precisely cut shape, since it does not have a protrude laterally beyond the inner collar to disturb can. ^

In the present shown in the drawing. Embodiment are the film hinge 7 and thus connected the hinged cover 8 in longitudinal stretching of the rectangular: - basic shape having closure member 5 arranged. The size of the hinged cover 8 can per se can be chosen arbitrarily and is based on the requirements of the customer, of course the fact must be taken into account that the opening area 11 must be large enough to remove a filling material without any effort to ensure. It is easily possible and is part of the innovation, the film hinge 7 and connected to it the hinged cover 8 also transversely to the longitudinal extension of the closure member 5 to be arranged.

After completion of the container 1 on the one hand and the closing organ 5 on the other hand is the latter, after the Foil l6 from below onto the end face 15 of the inside, collar is sealed, applied to the container 1 in the manner of a snap-on lid, the interlocking between the two elements taking place as shown above and in FIG. It goes without saying that the application of the closure member 5 only takes place when the container is already is filled, as a result of the sealed film 16 It is no longer possible to fill the container after the closure member 5 has been applied.

The application of the closure member 5 to the container 1 can be used with the hinged lid open or closed 8, although the latter case will probably be preferred. For the first removal of the product the hinged cover 8 is opened. Do that can open this be released because he is in his position, as shown in Figure 4, which is his rest position, remains. -> .- ...
