Closure fittings, especially for closing containers made of sheet metal

The innovation relates to a locking device, in particular for closing containers made of sheet metal, consisting of a snap-on lid made of plastic and means for holding an accessory part, e.g. a measuring or dosing spoon.

Closure sets of the above type are known. So is For example, by DE-GM 69 18 781 a design described in which a measuring spoon on the underside of the Snap cover is attached by means of clamp-like cooperating retaining webs.

In the present case, a film that is folded with the edge of the fuselage serves as a kind of guarantee seal.

The disadvantage of this type of closure is that this type of attachment of the spoon not only increase the cost of the lid, because the shape required for it is relatively complicated and is expensive, rather also when storing the spoon Take special care when not in use, as you have to make sure that the spoon is actually through the clamp is fixed. Last but not least, the guarantee film closure has the disadvantage that a separate one is required for attaching it Operation is necessary and an additional tool, for example, for opening the product before removing it for the first time a knife, is needed.

DE-GM 84 11 045.7 proposes a design in which the metal container is closed by a tear-open lid, vmd the measuring or dosing spoon between the tear-off lid and an inner fuselage recess fixed in position or outside the lid in Connection is held with a snap-type outer cover.

The disadvantage of this embodiment is that it only then can be realized if can bodies with an additional indentation on the body or with an additional indentation on the Tear-open lid or a special structural design of the spoon used to reduce it when not in use conditions that, on the one hand, limit the scope of use and, on the other hand, the manufacturing costs of this type of packaging increase additional manufacturing steps.

It has already been practiced, closed with push-in lids To design cans in the sense of the generic term in such a way that A foil insert with molded cavities for accessories was folded in between the cover ring and the fuselage.

The disadvantage of this design is that the film is removed prior to initial removal must be cut out of the product, for which a separate tool, so for example a knife, is required. the The foil must then be removed completely.

The measuring spoon can only be used when not in use at the moment - if you want to refrain from storing the spoon completely separately be placed in the contents, a measure that is not necessarily hygienic when it is removed and further contents are removed is, a disadvantage that also arises in the embodiment according to DE-GM 84 11 045.7.

The task of the innovation is to remedy this. The main aim of the innovation - while avoiding the disadvantages of the known designs - the design according to the innovation further unified-

multiplied and thus also cheaper, thereby a simplification goes hand in hand with handling, which includes, among other things, facilitating :: opening, immediate and problem-free access to the measuring spoon, easy lifting of the film and advantageous reclosing option extends where the measuring spoon is reliable and can be kept in a visible place.

This object is achieved according to the innovation in that the snap cover, which in a known manner on his Has inner and outer collar adjoining the edge of the lid base in the profile of an inverted U, the radial distance is designed between the inner and outer collar so that the open end of the fuselage, preferably provided with a border or the like of the container in the closed state positively and / or non-positively is comprised, is combined with a film insert made of plastic, which is shaped in the direction of the interior of the container, preferably Forming at least one cavity for receiving the accessory part, is deformed, and has a flange at the edge, which is dimensioned and / or shaped so that it rests loosely on the border of the body end of the container.

The design according to the innovation designed in this way is extremely overall simple in their structure and in their handling. The guarantee lock is opened without any special aids and without special effort. After lifting the lid, the spoon can be accessed immediately and without problems. By simply lifting off the film ensures quick access to the product, although the film is not being lifted off damaged. When not in use at the moment, the foil and the snap-on lid can be reused and put in their original locking position are set back, with the foil insert as a receptacle for the measuring spoon when not in use serves and is available at any time without having to use the spoon by hand or another device when removing the product again must be sought out of the product.

Another feature of the innovation is the flange of the foil insert positively adapted to the top of the border. This provides a stabilization in an advantageous manner generated by the position of the foil insert *

According to a further feature of the innovation, there is an advantageous, particularly simple one that can be canceled without any special expenditure of force Guarantee of the snap-on lid or the entire locking mechanism is achieved in that the outer collar of the snap-on lid has in a manner known per se a free ring-like end which is connected via a plurality of predetermined breaking connecting webs is connected to the outer collar and form-fitting by hot deformation can be molded onto the container wall.

According to a further feature of the innovation, the base of the snap-on cover has an enlarged cavity raised to the outside on. This measure has the advantage that, in addition to the measuring spoon inserted in the foil insert, also above the foil insert Accessories, for example an admixture, in bags or packages can be accommodated.

f To improve the locking seat of the snap-on cover points According to a further feature of the innovation, the outer wall of the inner collar has a protruding wall part.

Finally, in order to facilitate the removal of the snap dachshund, the innovation is provided according to a further feature, the Snap cover at the level of the preferably horizontal transition area between the inner and outer collar an inwardly directed to provide known wall section which ends with an edge which has a tendon-like position.

The innovation is explained in more detail below using an exemplary embodiment that is shown in the drawing.

Show it:

FIG. 1 shows a sectional view of the side view of the lock fitting according to the invention in the locked position on a tin container

Figure 2 shows the top view of the snap cover according to the innovation

FIG. 3 shows detail A according to FIG. 1 in an enlarged illustration

1 with the upper part of a body of a container made of sheet metal is referred to in Figures 1 and 3 of the drawing, which is preferably is cylindrical, but can also have a different configuration, for example oval-conical shape. In itself it is with regard to the size and thus the nominal content There are no restrictions on the container in connection with the innovation, but the content is between 1,000 and 2,500 grams to be given preference.

The free end of the fuselage 1 ends, as can be seen in particular from FIG. 3, in a border 2 of round cross section. These can, depending on the type of container, but also, for example, in cross-section, be long-oval or the like.

With regard to the fuselage 1, this also results in the present exemplary embodiment (see Figure 3) that the transition from the cylindrical fuselage wall in the border 2 over a cn known retracted sloping wall section 3 takes place.

The snap-on lid of the lock fitting according to the innovation is general denoted by 4. He has a cover base 5 which radially outwards into an upwardly directed vertical inner collar 6 passes, which together with the outer collar 7 in

Profile forms an inverted U. From the drawing, in particular from FIG. 3, it is clear that the radial distance between the inner collar 6 and the collar 7 is designed so that the border 2 of the fuselage 1 in the closed state of the Lid is positively and / or non-positively encompassed, the lid thus closes the container by a good positionally fixed seat.

From Figure 3 it can also be seen that the Äußern.andung of the inner collar 6 has a bulging wall part 6a, which is used to further improve the closed position of the snap-on lid 4 is used, wherein the bulging wall part 6a is designed in an arc-shaped manner in order to facilitate the removal and replacement of the Cover 4 to be able to make practically "jerk-free" against the resistance of the protrusion 6a.

According to the innovation, the snap cover 4 is designed as a guarantee lock. For this purpose, the outer collar 7 of the snap-on cover has a free ring-like end 8 in a manner known per se on, which is connected to the outer collar 7 via a plurality of predetermined breaking connecting webs 9 and is positively locked by hot deformation can be molded onto the container wall 1 or 3, respectively. The dashed representation of the ring-like end 8 'shows the molded one Location.

According to the innovation, the snap-on cover 4 continues to have a film insert 10 combined from plastic, which in the direction of the container interior I (see Figure 1) gives shape, preferably forming at least one cavity 11 for receiving an accessory part, is deformed. As can be seen from FIG. 1, the deformation 11 is matched to the shape of a measuring spoon. Such a one Deformation is known per se.

On the edge side, the film insert 10 has a flange 12 which comes to lie loosely in the closed position on the border 2 and by putting on the snap cover 4 by means of the pro

fils of the inverted U between inner and outer collar (6.7) is fixed in position. The flange 12 can either be flat or have a curved shape that corresponds to the rounding of the Bordierung 2 practically corresponds or this is adapted. The embodiment of Figure 3 indicates the last-mentioned embodiment at.

FIG. 3 of the drawing also shows that vertical wall parts of the film insert 10 form a positive fit on the outer wall of the inner collar 6 are in contact. In this way, the film insert 10 is stabilized in an advantageous manner.

According to the exemplary embodiment according to FIG. 1, the bottom 5 of the snap-on cover 4 has an outwardly raised area in a partial area Cavity 13, the outer wall of which is practically with the horizontal The transition area 76 between the inner and outer collar (6,7) is in alignment. This additional cavity 13 can serve to Additional accessories, for example packets or bags of admixture preparations or the like.

For better handling of the snap cover 4, in particular for lifting it out of its closed position, it preferably has at the level of the horizontal outer transition area 76 - the other one for centering stacking the same closed Containers serving with each other ring portion 77 carries - a radially inwardly directed adjoining the inner collar 6 wall section 14 known per se, which ends with an edge 15 (see FIG. 2) in a tendon-like position.

As already indicated above, the locking position of the lock fitting according to the innovation is shown in FIG. To open the container for the first time, the ring-like end 8, 8 ^{1 is} separated from the outer collar 7 by tearing it off diagonally outwards via the predetermined breaking connection webs 9, which is done manually without any effort, but also by means of a non-illustrated, e.g.

like handle, which is provided at the ring-like end 8, can take place. After that, the snap-on cover 4 is moved vertically lifted at the top with the help of the wall section 14 serving as a handle, which is gripped from behind. The material of the Sehnappdeckels 4 is set so that the opening resistance through the bulging wall part 6a of the inner collar 6 without Difficulty can be overcome.

Now the measuring or dosing spoon is accessible, which is located in the cavity 11 and its handle in the elongated area 11a is at rest.

The film insert 10, which rests loosely with its flange 12 on the border 2, can now be used to remove the filling material Difficulty being lifted off.

If the product is not in use at the moment, the container can be closed in the simplest way by removing the foil insert 10 hangs back in the box, the edge flange 12 of the

rests. Subsequently, the measuring spoon is again inserted into the cavity 11, 11 a and the snap-on lid 4 is put back on, which the Foil insert 10 fixed and thus closes the filling material practically tightly.
