"Container made of plastic and on a snap-on cover

The invention relates to a known container made of plastic with an edge bead and a snap-on lid with a lid edge that overlaps the edge bead of the container. The outer ring part of this lid edge has a bead ring on its side facing the edge of the container, which lies under the edge bead of the container after the lid has been snapped on.

The known containers of this type have the disadvantage that they are difficult to open and the lid and/or the container are deformed. In particular, once a lid has been removed, it is not possible to put it back on tightly.

The invention is based on the task of designing such a container with a lid in such a way that the lid can be removed without difficulty and can also be replaced completely tightly, whereby it should still be recognizable from the outside that the lid has been removed.

This object is achieved according to the invention in that at a point on the circumference of the outer ring part of the overlapping lid edge one or more

l There are predetermined breaking lines that run approximately parallel to the lid axis, starting from the lower edge of the outer ring part.

r 5 The first easy removal of the lid is thereby

The section of the outer ring of the lid adjacent to the predetermined breaking lines has a recess on the underside. This recess is then conveniently chosen ^to be large enough so that one can grasp the lower ring part of a snapped-on lid with one's fingers and swing the section in question upwards while simultaneously breaking the predetermined breaking lines on both sides and then pull the lid off the container. 10

This lifting of the lid is made even easier by the fact that the section located between two adjacent predetermined breaking lines is bent outwards at the lower free edge, thereby forming a gripping tab that makes it easier to pull up the section in question while simultaneously tearing open the edge of the lid along the predetermined breaking lines. It is sufficient if the bent lower edge of the section in question forms an acute angle with the adjacent

Parts of the sweeter ring part of the lid edge.

¹ Jn; to prevent accidental removal of a snapped-on lid by hitting the grip tab and to give the container with the snapped-on lid a closed appearance, the container is provided with a radially outward-projecting ring projection below its edge bead, whereby the edge of a snapped-on lid is so close to the ring projection on the underside that it is not possible to reach in with your fingers between the two. Reaching in and thus removing the lid is only possible at the point of the recess or the bent grip tab provided there.

Finally, it is preferably provided that the lid is stackable with other identical lids. This is

known catfish is achieved by the fact that the corresponding parts of the overlapping lid edge are slightly conical.

The invention is explained in more detail below in an embodiment example with reference to the drawing.

Fig. 3 is an enlarged sectional view along the line III-III in Fig. 1 of the upper container edge and the overlapping edge of a snapped-on lid and

Fig. 4 Two lids stacked on top of each other.

As can be seen from Fig. 1, the outer ring of the edge 3 of a snapped-on lid 2, which extends over the upper edge of the container 1, has an interruption in the form of a grip tab 4, which is delimited on both sides by slots 5 and 6 and is recessed at the bottom relative to the remaining sweeter ring part of the lid edge.

Below the overlapping edge of the lid is 30

An annular projection 9 projects approximately radially outwards from the container 1.

The continuous lid edge 7 is located so close above this ring projection that it is not possible to reach in with the fingers. Only at the point where the grip tab 4 is formed by a recess is the distance to the ring projection 9 so large that one can easily reach in with the fingers and pull up the grip tab 4.

As can be seen from Fig. 2, the two gates 5 and 6 are closed off at the bottom by narrow webs 5' and 6 ^' , so that there, below the lower edge 10 of the handle tab 4, a connection is provided with the continuous lid edge 7 adjacent on both sides.

As can be seen from Mg. 3, the upper edge of the

tci 9 I in Ik a naiiuffuis«. &ugr;&tgr; ei acricii , uci tun uciii overlapping lid edge 3 is enclosed. Just below the edge bead 8 on the inside of the outer ring part of the overlapping lid edge 3 there is a bead ring 12 which, after the lid 2 has been snapped on, lies under the edge bead 8 and initially prevents the lid from being lifted off.

An annular projection 9 projects radially from the upper, approximately cylindrical edge part of the container 1 to such an extent that its outer edge is flush with the continuous lid edge 7 of a snapped-on lid or projects slightly outwards beyond this lid edge. The distance between the annular projection and the continuous lid edge is so small that it is not possible to reach into it with your fingers.

In Fig. 3 it can also be seen that at this point on the circumference the outer ring part of the overlapping lid edge 3 is drawn in and is designed as a gripping tab 4 with an edge 10 bent outwards below the bead ring 12. At this point, fingers can reach into the space between the edge 10 and the ring projection 9 and the gripping tab 4 can be pulled up in the direction of the arrow. The webs 5 ¹ and 6 ¹ shown in Fig. 2 are then torn off and the gripping tab 4 can be bent up into position 4*. A further pull on the gripping tab outwards and to

In Fig. 4, a lid 2 of the aforementioned type with an overlapping lid edge 3 and an inner bead ring is shown, on which a second, identical lid 2a with a lid edge 3a is stacked.
