Abstract

The upper container rim (12) of a container which, like the lid (11), is made from plastic, for example a container for refrigerated products (10), is formed from two flanges (13, 14) which converge in an upward-directed point (15) and which are inclined in the same direction or different directions relative to the vertical. In the transition region between the inner flange (13) and the container wall (16) a peripheral groove (17) is provided, which is open towards the inside of the container. The lid (11) possesses a closing flange (18) and a bearing flange (20) adjacent thereto and forming a transition into the lid wall (21). The closing flange (18) and bearing flange (20) bear sealingly on the flanges (14, 13) of the container rim (12). By means of a latching web (19) on the one hand and a beading (22) on the other hand the lid (11) is latched relative to the outer flange (14) or within the groove or channel (17). <IMAGE>

Description

The present invention relates to a plastic manufactured containers, e.g. Freezer or food storage container, with also made of plastic lid that the upper container edge can be placed sealingly.

Containers, e.g. Freezer or food storage containers, the previous mentioned type are in various embodiments knows.

With such containers, e.g. Freezing or keeping fresh cans, it comes among other things to make one as dense as possible To achieve completion through the lid. One is still endeavors to remove such containers, e.g. Freeze or Frischhal to build cans as easily as possible, i.e. relatively to be thin-walled. However, this has again unpleasant consequence that a practically tight conclusion is complicated by the lid.

The present invention is based on the object  a container, e.g. Freezer or food storage container, the Generic type to create, in particular characterized in that a tight seal by the Cover practically exclusively through the design of the Container edge and the corresponding lid edge ge is guaranteed.

This object is achieved in that the upper container edge of two in one upwards white send tip converging, opposite the plumb bob th legs inclined in the same direction or in the same direction is formed, one of which is in the container wall passes and the other abge from the container wall turns and is directed downward, being in transition area between the container wall and the itself Subsequent legs open to the inside of the container ne and completely circumferential groove or groove provided and that the lid in its edge area with a circumferential closure leg is provided, which in Closed position on the outer web of the container rim rests and at least in the area of the tip of the container terrandes is supported.

With such a construction the container, e.g. Freezer or food storage container, in the area around the container Extremely stable and even with a thin-walled version inherently stiff and at least on the outer web of the container edge of the closure leg Cover is a relatively large and therefore high density coverage between the container  edge itself and the lid achieved.

After further training of the subject of the invention provided that located on the closure leg of the lid one in the closed state on the in the container wall going web of the container edge lying and in the Cover wall connecting transition leg connects.

Through this additional support leg is a white tere sealing surface between the edge of the container and the lid and there with a further improvement in the sealing in the closure condition reached.

A development of the invention provides that the Ver final leg the outer leg of the container rim protrudes downward and one the free end of the outer Has thigh-engaging locking web.

As a result, an easily producible latching between the lid and container rim.

Such latching can also - if necessary also additionally - be caused by the fact that in the over aisle area between the lid wall and the support a bead that can be snapped into the groove or groove is provided.

Embodiments of the invention are in the accompanying th drawings and are shown in more detail below described. Show it:  

Fig. 1 shows a cross section through a container according to the Invention, such as freezer or food storage container, with the lid on

Fig. 2-5 sectional views through the edge region of the container, such as freezing or fresh food containers, after further Ausführungsbei play the invention.

The container shown in Fig. 1, such as freezer or food storage container, ( 10 ) is made of plastic just like the reference 11 provided with the lid.

The lid 11 can be placed sealingly on the upper container edge 12 .

This upper edge of the container 12 is formed from two legs 13 and 14 , which converge in an upward-pointing tip 15 and can run in the same sense or in the same sense in the opposite direction to the vertical.

The leg provided with the reference numeral 13 merges into the container wall 16 , while the outer leg provided with the reference sign 14 facing away from the container wall 16 and is directed downward.

In the transition area between the leg 13 and the loading container wall 16 , a groove or groove 17 is provided, which is open to the interior of the container and completely rotates in the container edge region 12 .

The lid 11 is provided in its edge region with a connecting leg 18 which rests on the outer leg 14 of the container rim 12 . The United circuit leg 18 projects beyond the outer leg 14 of the container rim 12 downward and is equipped in this area with a locking web 19 engaging under the outer leg 14 .

At the closure leg 18 is a support leg 20 , which rests with the lid on the inside, in the container wall 16 passing leg 13 of the container rim 12 .

The support leg 20 in turn merges into the cover wall 21 and in the transition area a bead 22 is easily seen, which can be snapped into the aforementioned groove or groove 17 .

In the embodiments of the invention according to FIGS. 2 to 5, the construction of the container edge 12 is exactly the same as in the embodiment shown in FIG. 1, only the design of the lid edge is different, so that in the following in particular the different constructions the edge of the lid is received.

Thus, in the exemplary embodiment according to FIG. 2, to improve the fixing of the lid 11 at the upper container edge 12, only in the transition region between the bearing leg 20 and the lid wall 21, a bead 22 is seen before, which can be snapped into the groove or groove 17 of the lid rim 12 is. The closure leg 18 of the lid edge, however, is only on the outer leg 14 of the upper container edge, without being additionally fixed here.

In the exemplary embodiment according to FIG. 3, the lid 11 is provided exclusively with a closure leg 18 , which lies sealingly on the outer leg 14 of the upper container edge 12 . A shoulder 23 between the closure leg 18 and the lid wall 23 has the effect that the closure leg 18 is supported in the area of the tip 15 of the upper container edge 12 , so that the lid 11 can only be pressed onto the upper container edge 12 to a predetermined extent . The risk of damage to the lid 11 in its edge area is avoided. Rela tively also in this simple lid design ensures a high sealing, since surface by the angle on the outer closure's 14 legs 18 resting a large sealing results.

In the embodiment according to FIG. 4 is a positive and / or positive connection within the meaning of the Implementing approximately examples of FIGS. Been dispensed 1 and 2, the lid 11 but is in turn provided with an outer Ver circuit leg 18 and an adjoining support arm 20 , wherein the outer closure leg 18 rests in a manner now described on the outer web 14 and the support leg 20 on the inner leg 13 of the upper container rim 12 sealing.

In Fig. 5 an embodiment of the invention is provided, in which the closure leg 18 of the lid 11, the outer leg 14 of the upper container edge 12 as the protrudes downwards and is provided in this area with an integrally molded locking web 19 which the free end of the outer leg 14 engages. By a paragraph 23 in the transition region between the closure leg 18 and the lid wall 21 is again a proper position of the lid 11 be guaranteed with respect to the upper container rim 12 .

The illustrated and described embodiments of the invention show that with the same design of the upper container edge 12 there are various possibilities to use differently designed lid constructions depending on the requirement or the purpose of use. In practice, one will undoubtedly take into account the intended applications in each case and, with regard to the lid construction, ensure that the lid 11 is more or less securely fixed relative to the upper container edge 12 .
