Description

The Invention relates to a lid for a storage container, which on at least two opposite side surfaces each having at least one locking projection, wherein the Cover at least two locking tabs for engagement in the locking projections of the storage container and a circumferential sealing ring which is attached from a perpendicular to a lid plane surrounded by surrounding Kragrand.

Such a cover is from the DE-U 6942624 known and used for sealing reservoirs. By the locking connection of the Kragrandes with corresponding projections on the reservoir an inserted seal which presses from above onto the container edge, compressed, so that an airtight connection between the lid and reservoir is achieved. To release the lid, it is necessary to claw your fingers under the Kragrand of the lid and this tear away beyond the locking point out. This mode of operation is very uncomfortable and may require the use of lever tools, which in turn can lead to damage of the lid and / or reservoir and / or seal in particularly tightly closing lids.

From the DE 203 20 088 U1 is also a generic lid known. The laterally formed locking tabs have proven to be so far as a particularly secure, liquid-tight connection with the pressing of the tabs can be achieved. The tabs are a little way over the locking point on Kragrand over and thus serve as a lever for opening the locking connection. The opening is easily and conveniently possible via the individually graspable and liftable tabs. The disadvantage of these known lids consists solely in the fact that the user when closing all the tabs must be successively individually over the detent point and in particular must always operate in pairs the opposite tabs.

task The present invention is therefore a lid of the above so called to develop that both a simple opening of the set on a reservoir and locked it Cover is possible, as well as a simple placement of the Lids and latching on the reservoir.

Solved This object is achieved according to the present invention in that the locking tabs as elongated segments are formed of the Kragrandes and of the fixed areas of the Kragrandes are separated, with the locking tabs each about a flexible connecting web on a thermoplastic elastomer are connected laterally to the fixed areas of the Kragrandes.

The training according to the invention achieves the following advantages:
The locking tabs remain movable despite the flexible connection to the fixed areas of the lid, so that they can be easily lifted just when opening, at least so far that the nested edges of the locking tabs and the storage container are detached from each other.

On On the other hand, the flexible connection creates a spring effect scored which retracts the locking tabs again in their original position. In this initial position, the locking tabs are nothing else than Segments of the circumferential Kragrandes, which the edge of the storage container includes and thus the resting areas on the storage container embraces.

By The flexible connection makes it possible to easily cover from the top of the storage box. By appropriate design of the locking projections on the Locking tabs and the locking projections on the storage container, For example, with bevels, the locking tabs when pushing the lid slightly outwards deflected until the locking projections of the locking tabs under the locking projections of the storage container to grab. After overcoming the locking point is then the locking tab automatically back to the storage container used, so that the locking projection jump under the Verriegelungsvor accordingly is held and unintentional release of the locking connection is avoided.

The Snap tabs are as it were like pre-stressed rubber bands used on the storage container.

To the Just have to release just the locking tabs slightly against the resistance of the flexible connecting webs are deflected. The connecting webs of the thermoplastic elastomer are doing stretched like a thin rubber skin.

Of the made of a plastic such as polypropylene lid has solid Regions of the Kragrandes, which is in a rectangular lid, for example around the four corners. Of these, the locking tabs, each over a substantial portion of the length each side edge, in relation to the rest Hard component of the plastic completely decoupled. The areas in between are filled with the elastomeric plastic.

Preferably, the sealing ring is formed directly on the underside of the lid in such a way that the thermoplastic elastomer is materially connected to the hard plastic portion of the lid and the sealing ring sets the storage container from the top of the top.

The Connecting webs between the movable segments of the Kragrandes at the locking tabs and the fixed areas, such as the corners, then takes place via radiating outward reaching Distances of the sealing ring, which serve as a connecting web. This results in a particularly simple production, since the sealing ring and at least some of the adjoining connecting bridges can be made in an injection molding process.

at a rectangular cover are, for example, injection points in the middle of the respective narrow sides chosen, so that the melt can flow from there into the corner areas and Finally, coming from both sides, in about the Middle of the long side edge united and the continuous sealing ring formed.

The Invention will be described below with reference to an embodiment explained in more detail with reference to the drawings.

The Figures show in detail:

1 a lid according to the invention in a perspective view from above;

2 a lid in perspective view from below;

3 a lid in perspective view in side view;

4 the corner region of a lid in perspective view according to 2 from underneath;

5 a storage container with lid in a perspective view from above; and

6 a section through a storage container with lid.

In 1 is a lid according to the invention 10 shown. Starting from a central, here rectangular shaped lid surface 11 the lid rises 10 in the border area initially bead-like and then sinks into a Kragrand 15 down again. At the side edges are each latching tabs 12.1 . 12.2 educated. These consist of one segment at the top 15.1 . 15.2 of the Kragrand 15 , From a corner area 15.5 are the upper segments 15.1 . 15.2 the locking tabs 12.1 . 12.2 through connecting bridges 14.1 . 14.2 separated. The connecting bridges 14.1 . 14.2 are in 1 in the form of solid black areas that extend radially outward over the entire bead-like area of the lid edge. These areas consist of an elastomeric component.

At the in 2 The view from below in the lid is recognizable as the connecting webs 14.1 . 14.2 ... 14.8 outside to the circumferential sealing ring 14 connect. If one compares the representations after the 1 and 2 , it is clear that in the preferred embodiment of the circumferential sealing ring 14 only visible on the lower side of the lid.

On the other hand, at the top of the lid (see. 1 ), the elastomeric component which seals the seal 14 formed, covered by a layer of a hard thermoplastic material. Only the areas of the connecting webs 14.1 , ... 14.8 are completely free of hard plastic components and are made exclusively of elastomeric plastic.

The side view according to 3 shows in particular the formation of the locking tabs 12.1 . 12.2 . 12.3 , They are as a slightly outwardly spread extension of the corresponding segments on the Kragrand 15 educated.

4 shows a corner of a lid 10 in detailed view from below, taking again the seamless transition of the endless sealing ring 14 in the radial extensions, which are the connecting bridges 14.1 . 14.2 make it clear.

At the locking tabs 12.1 . 12.2 are the stop edges 16.1 . 16.2 recognizable, which in conjunction with a corresponding locking edge 22 on the storage box 20 (see. 6 ) for the positive connection between the lid 10 and storage containers 20 to care.

The up to the locking projection 16.1 . 16.2 reaching bridges 13 serve to the bending stiffness of the locking tab 12.2 to increase, so that it is ensured that not only that part is bent at the locking tab by the user, which projects beyond the locking projection downwards, but that just just the segment 15.1 . 15.2 on the Kragrand is deflected accordingly, so that the locking edges 16.1 . 16.2 can be pivoted out of its locking position and the locking tabs of the locking projections 22 on the storage box 20 come free.

In addition, the webs are arranged on both sides of the housing-side locking projections and thus form a positive centering aid for the position of the lid relative to the Aufbewah container, especially for containers with a round shape.

5 shows a combination of a lid 10 with an upwardly open, cup-shaped storage container 20 , as used in particular as a fresh food can in the home.

The storage container 20 owns, as in particular the sectional representation in 6 shows, a Kragrand 22 which initially adjoins the container outer wall at right angles and which is set obliquely downward towards the outside. It has such a length that, considering the elasticity of the plastic used, it can sufficiently deflect away when the lid 10 is pressed from above. Once when pressing the lid 10 its locking edge 16 the tip of the locking projection 22 on the storage box 20 has happened, the locking projection springs 22 back again, clamped form-fitting in front of the locking edge 16 and holds the lid 10 firmly on the storage container 20 ,
