"<! ll when full, containers, especially buckets, made of plastic that can be stacked /

The innovation relates to a stackable one when full Containers, in particular buckets, of plastic with lids.

In order to make a bucket-like plastic container airtight and watertight, it is known to use the lid of the Supported with a flange against the inside of the container wall, cover the container rim bead with a channel ring allow,,

If these known containers are stacked, i.e. a bucket placed on the lid of the one below, so the air-

and watertight closure no longer secured. Also is this conclusion was not guaranteed in the case of rough handling of the bucket, e.g. when knocking over

These disadvantages are overcome in the container of the innovation in that the lid between its central part and the gutter ring has a raised edge stiffened and supported by radial ribs, which is used to place the bottom flange edge of the container placed on the lid when stacking.

In another embodiment of the innovation, the disadvantages mentioned are overcome in that the cover has an edge recess between its central part and the channel ring, which - as known per se - is penetrated by radial stiffening ribs on which the bottom flange edge of the stacked on the cover The container rests _o The bottom of the bucket itself has in the center a cylinder stiffened by a ribbed star and triangular ribs, which support the bottom flange that works together with the formation of the lid.

In the following explanation of the drawing, the preferred embodiments, for example, schematically and partially in section the novelty will show the thought of

Innovation still further clarified ₀ In the drawing is:

Figo 1 is a side view of an embodiment of the innovation

Figo 2 is a plan view of a bottom section of the container according to Fig. 1,

3 shows a section through the cover connection in a Container according to FIG. 1 on an enlarged scale,

4 shows a plan view of a cover section with Container part,

Figo 5 is a section through a portion of a container according to Fig _o 1, which is seated a second container of the same design,

Έ ig _o 6 a section similar to Fig. 3 through a container of a slightly different design,

FIG _o 7 is a section according to line 7-7 of Figure 6 _o,

Ϊ t »

8 shows a view according to FIG. 6, which shows still another Embodiment of the lid shows and

FIG. 9 shows a section according to arrows 9-9 in FIG. 8.

In Figure "1-5 the container is 1o a bucket with a circular cross-section _o His coat is indicated at 12, The mantle is, as is" normal, slightly conically opened in buckets upwardly and downwardly closed by a bottom 14 with the lid 16 denotes "It has a horizontal surface 18 with a drawn-in ring edge 1o. The bucket 1o and its lid 16 are each made of plastic in an injection molding process and are provided with the support bracket 22"

The upper edge of the jacket 12 is provided with a bead 24, the undercut lower surface of which is denoted by 26. Below the bead 24- the jacket 12 carries several flange rings 28o They are connected by axially parallel ribs 3o and serve to "stiffen the edge of the bucket."

The support bracket 22 is pivotable in bearings 32. These consist of bores 38 in plates 34, which are integral with the bucket 1o are. The bores 38 are located between two annular ribs 2C and the side edges 36 of the plates 3 ^ o One of the ribs 3o is used for stiffening in the middle of the

Plate 34 at (Pig »1) ,, The plates 34 are supported on the other hand on support pieces 4o from ₀

The support pieces 4o have two parallel vertical legs 42 whose end faces are with 44 be22Lch.neto In this way the container (bucket) 1o with its contents can be held and carried on the carrying handle 22 without the risk of breaking out. Even a plurality of empty buckets of the same type can be stacked one inside the other (Fig, 5) ° There are then the laterally protruding support pieces 4o of a bucket the bead 24 of the lower bucket with the stop surfaces 44 on "

The bottom 14 of the bucket 1o, which is slightly bent inwards, is formed in one piece with the jacket 12 downwards Ring 46 protrudes and has a pipe section 5o in the middle, the gets up on the floor,

The ring 46 is via radial stiffening ribs 54, the pipe section 5o to the floor 14 via radial reinforcing ribs 52 connected

The ribs 52 and 54 represent short triangles and are therefore saves material compared to known ribs running over the entire diameter of the base.

The cover * 16 has one on the edge of the horizontal surface 18

-φ

vertical flange 56, which rests on the inside of the jacket 12 of the bucket 1o (S ¹ Ig ₀ 1, 3 and 4) ₀ The flange 56 continues above the lid surface 18 in a channel ring 2o which extends over the edge bead 24 of the bucket 1o and whose vertical outer wall is marked with 58 »

The outer wall 58 of the trough ring 2o has inside a bead 6o, which the bottom 26 of the bucket edge bead 24 engages under (Figo 3) ο For sealing between the bead 24 and the groove ring 2o a hollow sealing ring 62 _O affects the elasticity of the sealing ring 62 with the bead 6o together as a snap closure of the lid 16 on the bucket 1o "On the outer wall 58 of the channel ring 2o there are short tabs 64 (Fig. 4) that are used to open and pull off the lid 16, they are just above the when the lid is on top stiffening ring 28 "The tabs 64- have an opening 66 for inserting a tool to pull off the cover 16,

It is important for the idea of the invention that only the relatively short tabs 64 the stiffening rings 28 laterally protrude ,, The stiffening rings 28 then also protect the

To be in front of it, lifted the lid unintentionally by applying force from below _o

Jigs 6 and 7 show another embodiment of the lid _, here denoted by 68. The bucket 10, on the other hand, is designed in the same way as in the embodiment described above. The lid 68 has a groove ring 7o> which is set to close the bucket 1o over the bead 24 ₀ The outer wall of the channel ring is ο 7 denoted by 72 _o

The horizontal part of the cover 68 is denoted by 76. As a continuation of the channel ring 7o, the cover 68 has a vertical flange 74, which rests on the inside of the jacket 12 of the bucket. The middle part of the cover 68 is sunk so that between the surface 76 and the flange 74 a downwardly penetrated by radial ribs 8o open annulus 78 is created. This annular space stiffened in this way also reinforces the edge of the bucket _{0 after the lid has been inserted}

The rib permeated annular space 78 at the same time stiffens the lid 68 which must bear the load of the stacked above buckets (Figure "6) _o the bottom flange of each bucket is stacked above the ceiling of the stiffened annular space 78.

8 and 9 show a third embodiment “The container

(Bucket) is marked with 82, his coat with 86 ur.d 9 ^. The coat has between parts 86 and 9 ^ - a paragraph 92, which is a retracted upwardly open and stiffened by radial ribs 112 annular space 11o of the cover 84 stands. Of the The cone angle of the casing part 94 and the cover part 1o6 are matched to one another »The cover 1o8 sits with a channel ring 1oo with an elastic sealing ring 1o4 in between the edge bead 96 of the bucket jacket 86, with an inner bead the outer wall 1o2 of the channel ring 1oo the lower surface 98 of the Bead 96 reaches under o The bottom 88 of the stacked over it The bucket sits directly on the lid surface 1o8 and engages over the lid 1o8 with an edge bead 9o “The edge bead stands on the radial ribs 112. The part 9 ^ - of the mantle is more conically opened than part 86.
