Description

The present invention relates to a plastic container with a test polygonal Flange, with a cover and at least one handle, the polygonal flange over a Part of the height of the container extends and contains tooth-shaped locking means on its front edges.

Getting a container stiff enough to hold large volumes is difficult, especially when the specific weight of the transported material is high, such as paint. The problem becomes even larger if the opening has to be large enough to be able to immerse a scooter, for example.

A lack of sufficient rigidity can then easily lead to the fact that during transport by the train or If a truck hits the side, the container is deformed or the lid is opened he follows.

Another difficulty in transport arises from the slipping of the standard pallets loaded and held together container.

In addition, in the case of containers, which are preferably al: Disposable containers are intended to be economical Her Position and material savings play a major role, with material savings also directly during transport comes to bear. It is therefore desirable to produce the container in one piece from injection molding.

From GB-PS 9 63 494 is! a container the entrance:

ίο described genus known, primarily al; reusable milk container is intended. However, because of its shape, this container must be:

at least 3 parts are put together, which makes its production significantly more expensive and unc In addition, it only has a small opening through which, for example, no scooter can be dipped.

From the DT-Gbm 74 00 383 a container with a square plan is known, which is a customary has all-round reinforcing rib, which, however, does not cause the lid to pop open when hitting the side: can prevent. In addition, this container does not have a “middle! against moving sideways.

In contrast, it is the task of the present one

Invention to improve the container described above to the effect that it despite its manufacture made of injection-molded plastic has the necessary stability for a bucket, so that the lid is aucl can not open by itself in the event of a lateral shock load, especially when transporting by truck.

The container that solves this task is characterized by the fact that the polygonal flange consists of a horizontal leg and one vertical leg angled from this on the outer leg and the on upper part of the container is arranged that edit tooth-shaped locking means on the vertical tavern are arranged that the handle is attached to the flange and that the lid on the upper edge of the koniscl upwardly widening container wall over a flange-like, outwardly protruding collar einra is attached.

In the following, some Ausführungsbeispie Ie of the invention are shown with reference to a drawing explained.

Fig. 12 shows a variant of the lid on the Fit top of body and

ρ jg 13 is another variant of the lid. Figure 1 · 2 and 3: the container comprises a body 1 having a polygonal flange 2 whose sides are provided with small ribs 4, wherein _he j flange openings to the handles 3 pass. For the transport throw the containers _ir jt the lid 5 on a pallet 6 (Fig. 2) arranged in such a way that the ribs 4,4a of one container engage in the ribs of the adjacent container (Fi ₆ .3). The container unit can then be connected to one another with a plastic band or with a band which shortens under the action of heat. The ribs prevent the containers from shifting in relation to one another during transport, and the flanges are strong enough to prevent the body from deforming in the event of impact.

The F i g. 4, 5, 6 and 7 represent a first variant. The basic shape of flange 7, in plan view, is square with corners beveled at 45 °, the cross-section of each flange (see FIG. 6) has the shape of an angle, the thickness of which in is approximately the same as that of the truncated cone 10. One of the legs of the angle, which is arranged perpendicular to the axis of the container, forms the upper plane of the flange and the other leg forms the front of the flange 7. A group of ribs, not shown, connects the front of the flange with the wall of the body. The flange 7 is located in the vicinity of the upper part of the conical container wall 10. On the front sides of the flange, groups of ribs 8, 8a, 8 />, 9 and 9a (see FIG. 7) are arranged alternately and perpendicularly to one another. So that these ribs can engage in those of an adjacent container, it is necessary that after a rotation through 180 ° with respect to the axis AA (FIG. 7), the ribs of groups Sb and 9 come to lie between the ribs of groups 8a and 9a. In this way it is possible, if two or more containers touch, to prevent a relative displacement of the containers in two directions.

In two of the beveled corners of the flange 7 openings 11 are arranged, which allow flexible Carrying handles 13 to carry out, these handles having small cylinders 14 at their ends, which in Recesses 11a engage in flange 7. Additional ribs 15 absorb the bending forces caused by the Pull on the handles during transport.

It goes without saying that the Traggnffe 13 by a single flexible handle can be replaced, in which case there is only a single one opening 11 at each of the opposite corners. The cover 12 (Fig. 6) will be described in detail below.

The F i g. 8 and 9 show another embodiment of the container. The octagonal flange 20 has four its front faces similar groups of ribs and 9, as described above. F i g. Fig. 10 shows the arrangement of the ribs 24 joining the front sides of the flange 20 with the container wall associate. These ribs are formed on four front sides of the flange to make the container easy to be able to grasp and manipulate, with the parts 16 and 23 of the flange taking on the role of handles. The ribs 2i, which delimit the parts 22 and 23, extend over a certain length of the body

along. . ,,,.

The conical container wall 10 extends over the Top of the flange 20 and forms a tab 36 on which the cover 12 is fitted.

The lid 12 includes a reinforced by ribs 37 central part 34, which is connected to the closure part of the Lid is connected by a "U" -I'-shaped and flexible wall 31, which allows the closure part to absorb impacts. The closure part is formed from a folded wall which the flap 36 clamped and the cover 12 on the tab 36 ίο formed, outwardly protruding collar 32 holds. A band made of plastic can be inserted into the notch 33 to close the cover attach. If the cover has to be closed tightly, a sealing ring can be inserted into the groove 38 will.

The bottom 28 of the container goes continuously through rounded transitions 29 and 30 to the conical Container wall 10 over, while the container wall is extended by a cylindrical part 25, the bottom 28 includes. This cylindrical part 25 is formed by ribs 26 evenly distributed over the circumference reinforced and can deform in the event of an impact and thus protect the floor 28.

The container and the lid are made of injection molding, e.g. B. made of a polyethylene with high Density. In the case of the container, the plastic compound is injected in the center 39 of the base, the Conditions for the distribution of the material during the injection through a series of ribs 27 that define the Injection point and the bottom of the body connect to be improved and the fillets 29 and 30 for contribute to further improvement of the injection. The same also applies to the ribs 35 of the cover 12.

Another embodiment is shown in Fig. 10, which represents one half of the container from below. The polygonal flange 50 contains 12 sides, each second side having means 51 for increasing the relative displacement of abutting containers impede. These means 51 have already been described above and are shown in FIG. 7 has been shown.

On two opposite sides of the flange a finger 51 is attached, which serves to one end to attach a flexible handle, not shown here, the axis of this finger 52 with a reinforcing rib 53 collapses and these reinforcing ribs play the same role as the ribs 21 in FIGS. 8 and 9.

The bottom 55 of the container also contains, as shown in FIG. 8, a cylindrical wall 54, which deform to absorb shock. To improve this absorption, connect relatively flexible ones Ribs 65 the bottom of the container with the wall 54, these ribs a certain angle α with a Form a radius, whereby they give way more easily 55 when impacted than if they were arranged radially.

The middle part of the bottom 55 contains a collar (see Fig. 13), which on the floor or on the Pallet rests when the container is full.

Experience teaches that in some cases the lid 60 rf6 must be very firm. To do this, removed the flexible part 31 of the lid 12, see F i g. and connects the middle part of the lid with the Locking tab by means of a wall 60, the rigidity of which by a series of ribs 58 and Isi.

The triangular ribs 58 leave part of the wall 60 free so that when two Containers on the cylindrical wall 54 of a container

centered at 60a on the lid of the other container, thereby facilitating the stacking of multiple containers. The small base of the ribs 59 coincide with the inner surface of the lid, while the portion 59a of the rib extends the inner wall of the locking tab. This arrangement allows the lids to be stacked on top of one another in an easy manner.
Another, shown in FIG. The possibility shown in FIG. 13 to reinforce the cover consists in lengthening the middle wall of the cover 67 and thus forming a kind of annular channel 62. By providing the latter with a group of ribs 61, the lid is stiffened, each rib having a flat part 61a extending the central wall and a triangular part 616 intended to center another container 63.
