Plastic packaging containers

The innovation "relates to a packaging container, For example a can, a bucket or the like, made of plastic with a plastic lid that can be pressed in, e.g. a snap-on lid with sealing lip, rear cover or the like.

Such packaging containers, which can be used for a large number of the most varied of filling goods, are known per se such packaging containers should be particularly guaranteed be that even after partial removal of the product, the lid seals well in the closed position. !, lan knows for the call different lid designs. A common type of cover is that the edge of the cover is arched is formed and in the closed position the arcuate outwardly bulging opening edge of the container encompasses. Another embodiment that is often used exists in that a known, conventional Sindrückdeckel is used with a press fit, its horizontal Flange in the locked position on the horizontal flange the edge of the container rests. Both embodiments kaben

sick proven itself

In the case of containers of this type, there is now also often a requirement for a seal, by means of which an original filling should be protected as visibly as possible before the filling material is removed for the first time. 3 ^{1 For} this purpose, it has already been proposed in plastic containers, in particular buckets, of the first type described above, to provide the sand end of the container on the one hand and the end of the lid on the other hand with an outwardly protruding flap provided with perforations, which are brought into congruence when the container is closed and provided with a sealing wire. On the opposite side of the container there is an eyelet-like injection molding on the edge of the lid and a hook-like injection molding on the container edge, which are connected to each other in a hinge-like manner prior to closing with the lid, so that after after sealing with a sealing wire, the lid can no longer be removed from the container. The disadvantage of such an embodiment is that when uncovering it is necessary to ensure that the corresponding parts of the lid rim and the container rim are first brought into line Beh older therefore requires special attention and can be time consuming.

There are. also, container exports already become known, on the circumference of the lid edge and the container edge a plurality of elements that are initially to be connected to one another all of which must be sealed separately in the following. For example, one knows an embodiment in the case of the sealing cams arranged on the edge of the container are provided which, when the lid is opened, by corresponding Reach through the edge recesses of the lid and protrude over the upper edge surface, fold open the compartment of the cover, the sealing cams, which each have through holes, are provided with a sealing wire « Also, this embodiment is relatively complicated and has the disadvantage that once again the individual Elements of the container edge on the one hand and lid edge on the other hand are brought into agreement nuts. A particular disadvantage in terms of effort is that each of the sealing parts provided for must be sealed if the container is to have an effective guarantee lock at all.

The task of the innovation is to provide a sealable packaging container to create made of plastic with a lid, which is simple and inexpensive while avoiding the above-mentioned disadvantages and which makes it possible in particular to close the container without the need for special items to be kept

Tampering is necessary, whereby a sealing wire is sufficient to ensure an effective guarantee lock reach. The innovation is that the edge of the container and lid distributes a plurality on the circumference arranged, essentially right outwardly protruding tabs provided with perforations of the same number and have circumferential layers which lie flat on top of one another in the closed position of the lid, a flap of the Edge end of the container or the lid with respect to 3-size and training is designed so that a hinge-like Connection with one of the flaps of the lid or the container is possible. In this embodiment needs you only have to bring a flap with the enlarged flap, which serves as a hinge, in connection and to close the lid, with all the other flaps of the lid and container automatically with one another come to cover. After that, a pair of flaps or all pairs of flaps can be replaced by a sealing wire or like. be sealed. The design allows the container to be closed completely mechanically, with one flap Due to its different size and shape, it is easy to find visually (-Search tab) <.

Another essential feature of the innovation is that one of the flaps of the edge of the container or the Lid is larger in its length than the other lobes, about two wall thicknesses higher than that

flap the other and place one between the edge and the perforation Slit for pushing through one of the tabs "has. Through this training is the already mentioned hinge-like connection of lid and container without difficulty enables «,

It has been found to be particularly advantageous if, according to a further feature of the inflation at the end of Container and lid are three offset from each other by 12o Lobes are arranged.

In order to ensure the tightest possible closure of the container in the To achieve the closure position of the lid points to a Another feature of the innovation is the edge end of the lid between the lobes facing inwards, the edge end of the container encompassing known locking edges.

The innovation is based on two embodiments that are shown in the drawing, explained in more detail below.

FIG. 6 shows the top view of the closed container according to FIG. 5

FIG. 7 shows the enlarged illustration of the closure position of the container and cover as a detail.

With 1 in Figure 1 of the drawing, a packaging container preferably conical in shape towards the bottom is from Plastic. Its opening margin 2 is -; like from the The same figure of the drawing can be seen - arched outwardly in an arched manner. The top of the container 1 furthermore has on two opposite sides of the container directly molded pockets 3 into which a support bracket 4? which is preferably made of metal, is suspended (Figure 3) ■>

The container 1 is closed by a snap-on lid 5 which has an annular sealing lip 6 which, in the closed position of the lid, lies against the inner wall of the container 1. "The lid 5 also has an arcuate lid edge 7? which engages around the arched outwardly curved opening edge 2 of the container 1 in the closed position. In order to achieve a secure, virtually sealed closure position, the R _a Ndende of the lid 5 is known per se locking edges 9 which engage around the edge 1o end of the arcuate opening edge of the container. 1 Figures 2 and 4 show this embodiment of the cover particularly clearly. On its upper side, the lid finally has an inwardly directed step 11, which serves to achieve a centering stacking of containers of the same type placed one on top of the other.

The edge end 1o of the container 1 has a plurality on the Circumferentially arranged, essentially horizontally outwardly protruding tabs 12, 12a. In the present embodiment there are three tabs that are offset by 12o ° from one another. The flap 12a is designed in the same way as the other flaps 12 in terms of its general training. Only in terms of its Size it is different from the others, in such a way that it is larger in its length and

■ is about two wall thicknesses higher than the other flaps 12. Each of the tabs 12, 12a has a hole 13 and the tab 12a also has between the perforation 13 and the edge end 1o a slot 14 ·

In the same way, the edge end 8 of the cover 5? in the Embodiment lying at the door, also three at 12o Staggered tabs 15 which have holes 16 of the same type. The tabs 15 of the cover 5 are all of the same type formed and correspond both in their shape and their size to the tabs 12 of the container 1. The arrangement height the flap 12 of the container 1 and 15 of the lid 5 is made so that in the closed position of the lid the lobes lie flat on top of each other »

As can now be seen in particular from FIG the container is so closed with such a design that initially one of the tabs 15 of the lid 5 (see right Part of Figure 1) inserted from above into the slot 14 of the tab 12a of the container 1 and the lid is then closed will »In doing so, like the right one, too Part of Figure 1 of the drawing shows - the tab 15 of the lid 5 flat under the tab 12a of the container 1 and through the same number and circumferential position of the remaining tabs 12, these will then also be flat during the final closing on each other. The locking edges 9? the one at the edge 8 of the lid

are each arranged between their lobes on the circumference, ■ grip around the edge of the container 1o and "form a tight seal. The container can subsequently by means 'A P 1OmMerung through the holes 13, 16 a tamper-evident obtain.

It should be emphasized again at this point that for the hinge-like connection with the tab 12a of the container, any of the tabs 15 of the lid can be used. In any case, the other lobes are from Lid and bucket on top of each other »

In the same way, it is now also possible - without deviating from the idea of hiring - the flap 12a instead of the Bead end ίο of the bucket 1, to be arranged at the edge end 8 of the lid. Such an arrangement can be seen in FIGS. 5 to 7, specifically in the case of a packaging container from Plastic with a different external shape and size ο For a better understanding, these are the same for this embodiment Parts have been given the same reference numerals, although some constructional differences, e.g. with regard to the type of push-in Cover 5 in contrast to the embodiment according to Figures 1 to 4 * exist. It is also used in the present If a repetitive description of the structure is dispensed with. It is only to be noted that in the case of the spatial

shape according to Figure 5 "to 7 around a cylindrical box 1, z.3. smaller dimensions. Unlike the first For example, the tab 12a is arranged here on the cover. To close the container 1, the lid 5 - preferably perpendicular - brought up to the container 1 in such a way that one of the tabs 12 of the container 1 through the slot 14 of the tab 12a of the cover 5 can be "threaded". Then the cover 5 is turned over horizontally and into the container opening pressed in (Figure 5) · Here, too, the tabs 12 of container 1 and cover 5 are again flat on top of one another. the hinge-like connection is shown in FIG.

The number of tabs arranged on the circumference of the container 1 and cover 5 does not need to be as in the present exemplary embodiment to remain limited to three, although this number has been found to be advantageous in itself. The outer contour of the tabs 12, 15 still does not need to be rectangular, as shown in the present exemplary embodiments, these can of course also be be round or otherwise designed.
