HOPPER WITH HAT COVER

The invention relates to a holder with a shrouded lid, ringed made of plastic, in which a groove located near the circumference of the cover surface fits snugly onto the mouth edge of the holder and wherein the apron of the cover can be accommodated. spaced from the nosing edge, around the container running U-shaped channel, consisting of a bottom flange and an upright edge, such that a thickening * running around the skirt engages underneath around the inside of the upright edge. thickening and wherein the upright edge can be turned outwardly from an upright position along an edge thinning beneath its thickening into a downwardly directed position.

Such a holder is known from US-A-4,171,062. This holder is difficult to open by hand because the bulge on the upright edge is drawn in under the resilience of the plastic. This drawback is even more pronounced if a welding connection is present between the upright edge and the apron. Welded joints are increasingly used * The connection can be continuous or discontinuous. for obtaining an airtight seal and / or security seal for detecting unauthorized opening of the container. A common phenomenon with stacked lid containers stacked on top of each other is that the lids of, especially, the bottom containers are pressed into the containers because the apron can freely deflect outwards. Although the apron of the holder according to US-A-4,171,062 is retained by the upright edge, the possibility still remains because the construction of the holder and lid is just such that the upright edge must give way when opened.

0402436 *? * ♦ * -2—

The object of the invention is to provide a container with lid of the type described above, which largely obviates the above-mentioned drawbacks.

This is accomplished in that the upright edge of the U-5 shaped channel extends upwardly to some distance above its thickening to form concentric and opposed portions of the upright edge and skirt with a closed container.

A container with a lid designed in this way offers the advantage that the part of the upright edge located concentrically with the apron above its thickening can now be used as a pushing edge for depositing the upright edge. A heat weld can now conveniently be arranged between the rather thin walls of the concentrically located parts. Preferably, so that sufficient edge remains for the pushing, this welded connection is placed near the point of application of the thickenings. . of apron and apron resp. edge. The presence of welded joints further reduces the deflection of the apron when the lid is loaded.

An advantageous embodiment is that in which the thinner is located at the point of engagement between the thickenings. This creates a sturdy base for turning over the part of the upright edge located above the dilution. The free end with its thickening is then located under the thinner so that the apron can press against the non-foldable part of the upright edge when the lid is loaded.

To increase the leverage of the upright edge, it may be preferable to lower the weld connection. To this end, provision can be made by providing at least between the point of engagement of the thickenings and the thinning of the upright edge in two concentric and opposite parts of the upright edge and the skirt.

In this latter embodiment, the apron cannot be diverted when loading the lid 35, in this last embodiment suitably prevented by enclosing the free end of the apron between parts of the upright below the level of the dilution. edge and the container wall.

For this purpose, the U-shaped channel can be narrowed on its bottom side or the free end of the apron can have a thickening 5, for example in the form of a side-facing flange. * A combination of the latter possibilities for confinement is also possible.

Partly due to the possible presence of a welded connection between the upright edge and the skirt, which welded joint may be located between the level of the dilution in the upright edge and the free end of the upright edge, relatively great forces will be exerted on the upright edge. must be applied in order to both break the weld and effect the deposition of the raised edge. It is therefore advantageous that the U-shaped channel below the level of the bottom flange has an extension running around the container. Preferably, radial partitions between the extension and the container wall are then also provided. This not only prevents the bottom flange from bending downwards under load, but the extension also offers the possibility of providing openings therein into which the taps of a handle can be inserted. The extension thus carried out can also serve as a stacking edge when nesting containers. When nesting, the mouth edges of the holders are then surrounded by the extension. The height of the radial partitions can be chosen such that telescoping of the holders, with clamps as an unfavorable side effect, is prevented from telescoping too far into each other.

The mouth edge of the container can be designed as a beaded edge that snaps in a groove in the lid adapted to the diameter of the beaded edge.

Although it is preferable to design the groove and the bead in such a way that after the edge has been turned over the lid can be lifted by hand without great difficulty, it may be advantageous to provide the lid with a pull tab in those circumstances where a Tightly bead bead engaging groove is required.

The invention will now be further elucidated on the basis of an exemplary embodiment shown in the drawing 8402436-4. In the drawing shows:

Fig. I a cross section of a container part and lid part according to the invention; FIG. 2 a variant of the embodiment according to FIG. 1, with a secured apron;

Fig. 3 another variant of the embodiment according to FIG. 1, and

Fig. 4 a variant of the embodiment according to FIG. 3 with a secured apron.

In the figures, like reference numerals refer to like parts.

The one shown in FIG. 1 container indicated by 1 has a bottom 2 and in this case a slightly conical wall 3 with a mouth edge 4. A U-shaped channel 5 running around the container is formed by a bottom flange 6 and an upright edge 7. The upright edge has a thinner 8 and a thickening 9. The upright edge 7 can be folded down around the thinner in the direction of arrow P, so that the thickening 9 is turned away above the thickening 13.

The lid indicated by 10 has a groove 11, in which the mouth edge 4 fits snugly, and an apron 12 which can be received in the U-shaped channel 5. The apron 12 has a bulge 13 which engages under the bulge 9 after the lid has been pressed on. A welded joint 14 can be arranged between the concentrically opposite parts of the upright edge 7 and the apron 12. The welded joint can also be applied at the location of the thickenings 9 and 13. The part of the upright edge 7 located above the thickening 9 or the welded joint 14 can be used according to the invention as a pushing edge for turning over the upright edge 7 along the dilution 8 and optionally for breaking a welded joint present.

The levels between which the welded joints are advantageously laid are shown in FIG. 1-4 marked with A, bottom level, and with B, top level.

Under clamping the muzzle edge in the groove, also 8402436 * f *. -5- means the embodiment in which the circumference of the part of the lid which is recessed in the holder lies clampingly sealing against the inner wall of the holder. Other versions are discussed below.

In FIG. 2, the thinner 15 is at a level between the thickenings 9 and 13. The part 16 of the upright edge forms with the bottom flange a reinforced base for the turning over of the part of the upright edge located above the thinner 15. Fig. 2 shows that the thickening 13 is designed in such a way that it does not press against a part of the upright edge which is intended to be foldable. The apron 10 is thus secured against deflection when the lid is loaded, for example in a stack of filled containers.

Fig. 3 shows an embodiment in which two concentric and opposite parts 17 and 17 respectively are provided below the point of engagement of the thickenings 9 and 13. 18 of resp. the raised edge 15 and the apron. A weld 16 can be arranged between said concentric parts.

Fig. 4 shows that the free end of the portion 18 of the apron 12 concentrically with the upright edge 7 is designed such, here with a thickening 19, and that the location of the thinning 15 is chosen such that the apron load on the lid does not press against a foldable part of the upright edge 7.

In Figs. 1-4 below the bottom flange 6 is indicated by an extension extending around the container. Between the extension 20 and the container wall 3 there are radial partitions 21. Two openings 22 arranged diametrically opposite each other in the extension 20 serve as tapping openings for inserting the taps of a handle.

In FIG. 4, a further embodiment of clamping the mouth edge in the lid groove is shown. The beaded mounting rim 23 fits snugly and clampingly into the groove opening 25 after being pressed through a constriction 24. In order to facilitate removal of the lid after the upturning rim with a strong clamping connection, provision can be made for a pull tab on the lid. An advantageous embodiment within the scope of the invention may also consist in a lid which is provided on its outer circumference with 84 02.4 3 6 u * -6- a light edge projecting horizontally above the U-shaped channel, such as for instance with 26 In Fig. . 3 and 4 filled in and drawn in dotted line. This edge edge can then optionally serve as a pull tab for lifting the lid, but it also has the advantage that the upright edge is protected against forces coming from above, which inadvertently cause the upright edge to tip over.

In Figures 1 * 4, A and B always indicate the levels between which the welded joints can be advantageously laid. Preferred levels can be indicated between these levels. For example, the 10 weld in FIG. 1 or 2 are arranged between the thickenings 9 and 13 or between the thickening 9 and the apron 12, while in FIG. 1 the weld can also be placed between the thickening 13 and the raised edge 7.

In Figures 1-4, for clarity, some space is left between the mouth edge and the lid. It is actually the intention that in this area there is an all-round contact surface between container and lid. Sealing lips, etc. known per se, can be provided in this area.

The height of the partitions 21 need not, as shown, be equal to the height of the extension 20, but can be adapted to the desired telescoping of the holders during nesting.

As stated, the upright edge 7 can easily be pushed down in the direction of arrow P (see Fig. 1) with a standing holder. Ergonomically, this is very advantageous because the holder stands firmly and both hands can be used to exert an essentially vertical downward force on the upright edge. This advantage is particularly evident if a welded connection is to be broken thereby.

It is recommended in circumstances where there is only little space between the upright edge 7 and the skirt 12 to slightly widen the top end of the upright edge, locally or all around, so that some more space is created for the fingers.

The fact that it is possible with the container with lid according to the invention to prevent the apron from diverting under load and thereby causing the lid to sink into the container, offers the advantage that the wall thickness of the lid can be smaller and / or more flexible plastic. 8402436 -7- \ can be used than usual ·

The container with lid can both be manufactured from the same or different plastics, such as polyethylene, polypropylene, copolymers of ethylene and / or propylene, as well as mixtures of said plastics.

The container according to the invention offers a wide range of uses and is particularly suitable as a packaging bucket in, for example, the food and paint industry, where buckets are inexpensive to manufacture, with good to airtight closable lids that are reusable and can be easily disposed of. applied and taken off.
