Abstract

The invention relates to a container comprising a removable cover (2) which is locked in the closed position, wherein the container (1), in the edge region of the open side, and the cover (2) have mutually engaging circumferential detent edges (11), wherein the container (1) has, underneath and in parallel with the detent edges (11), at least one reinforcement ridge (5) having at least one interruption (6) which is at least partially, and preferably mostly, covered by an opening tab (9) of the cover (2) in the circumferential direction.

Description

Container with a removable lid

The invention relates to a container with a removable lid according to the preamble of claim 1.

Such containers, which are preferably made of plastic, are used in many areas of application, for example for receiving free-flowing, pasty or free-flowing substrates.

In the closed position, the lid covers the filling and removal opening of the container and is latched to the container rim by means of a designed inverted edge, for which purpose both the container and the lid have latching edges that engage in one another.

To release the latching, the edge of the container associated with the lid has a tab which is pivotally connected relative to the container and relative to the edge of the container which is otherwise immobile with respect to the container.

When the opening tab is pivoted, the inverted edge of the lid is pressed approximately radially outwards, with the latching being released and the lid being pushed up at the same time.

Such a container with a lid is disclosed, for example, in EP 0565967 A1 and WO 03/076290 A1.

For sufficient rigidity of the container, in particular to be able to absorb the internal loads caused by the substrate in the container when the lid is removed, the container wall is dimensioned to be correspondingly thick, which is undesirable in many areas of application and is clearly oversized, especially for light substrates, and incidentally also involves relatively high production costs. The invention is therefore based on the object of further developing a container with a lid of the generic type in such a way that its load-bearing capacity is increased with a reduced wall thickness and its usability is improved.

This object is achieved by a container having the features of claim 1.

The inventive design of the container and the lid, in that the container has a reinforcing rib below the locking edges parallel thereto and preferably from constantly in the circumferential direction, the inherent rigidity of the container as a whole is significantly improved.

In this configuration, which can be accompanied by a wall thickness that is reduced compared to the prior art and consequently a reduction in weight, the container with a lid can also be used for substrates that are very light, for which the known containers were previously oversized and are therefore not accepted. That is, the usability of the container according to the invention is improved by a substantial factor.

According to the invention, the reinforcing rib is provided with at least one interruption, which is at least partially, preferably largely, covered by an opening tab of the cover in the circumferential direction.

This opening tab is comparable to that known from the prior art, arranged on the container and held pivotably on the outer edge of the lid, for example by means of a film hinge or the like.

The reinforcement rib can be designed differently in its cross section. For example, as a web aligned radially perpendicular to the container wall or as a channel open towards the lid.

The interruption of the reinforcing rib can also be formed as a terwand perpendicularly upstanding web on the container or as a channel open towards the cover, but set back in the radial direction compared to the amplification rib otherwise. However, it is also conceivable to dispense entirely with a reinforcing rib in the area of the interruption. According to the invention, the cover can also be designed in such a way that the inverted edge protrudes on both sides of the opening tab into the channel-shaped reinforcing rib, the opening tab being flush with the inverted edge or protruding radially beyond it.

In principle, the container and the lid can have a round, oval or multi-cornered base. However, the base area is preferably rectangular, in particular square, with the corners being rounded.

At least one interruption and thus an opening tab of the lid is provided in one curve, preferably in all four curves, which has advantages in particular when storing and transporting several such containers if several are arranged next to each other, in which case the opening tabs are in one jointly formed free space are, the cover can therefore not be pried open.

Easier handling can be achieved in that the lid and the container are designed in different colors, the opening tab is visually easier to recognize.

Furthermore, the lid can have a bulge on its upper side at least in some areas, preferably all around, at a distance from the outer edge area and the bottom of the container can be lower than the side wall, with the clear dimension of the circumferential side wall on the outside of the bottom approximately corresponding to the assigned external dimension of the lid in the area of the peripheral bead. This allows several containers to be stacked to form a column in which the containers are kept centered. Furthermore, the outside of the side surface can be used completely, for example for advertising purposes, since it can be viewed unhindered.

As mentioned, the container according to the invention is characterized above all by the fact that it can be minimized in terms of its wall thickness with high stability, which means that the container with a lid can be used for applications for which no optimal product has been available up to now was standing. An example is the use of the container as a plastic box with Gen external dimensions pointed out and a capacity of for example 0.75 to 1 liter, the recorded substrate can be free-flowing, pasty or liquid.

Further advantageous developments of the invention are characterized in the dependent claims.

Exemplary embodiments of the invention are described below with reference to the attached drawings.

FIG. 14 shows a longitudinal section of containers with lids stacked in a column

Figure 15 shows a section according to the marking XV in Figure 14.

Figure 1 shows a top view of a container 1, which in the example has an essentially square outline and which, as can be seen particularly clearly in Figures 3 and 4, has a snap-in edge 11 on the outside, which peripherally delimits the opening of the container has, which, as described later, corresponds to a locking edge of a lid.

Below the locking edge 11 is on the side wall 4 of the container 1 with Ab was and arranged in the circumferential direction a reinforcing rib 5, in the form of egg ner upwardly open channel. This reinforcing rib 5 is provided with several sub-interruptions 6, which are seen easily in the round corners of the container 1 and each in the example has a corresponding to the shape of the ampl kung rib 5 trained projection 7, which is smaller in its radial width than the ner Reinforcement rib 5. Instead of the groove-like shape of the projection 7 shown, it can also be designed as a radial web or such a projection 7 can be dispensed with entirely.

Opposite the side walls 4, a base 3 forming the base of the container 1 jumps back axially inwards in order to enable centering when containers 1 with lids 2 are stacked.

FIG. 5 shows a container 1 with the cover 2 in place, which can be seen in FIG. 6 as a plan view and in FIG. 7 in a longitudinal section.

In FIG. 8, which shows a section according to VIII in FIG. rib 5 is guided, with a locking edge of the inverted edge 8 corresponding to the locking edge 11 of the side wall 4 .

FIG. 9 shows a section IX-IX in FIG. In this corner area, i.e. largely covering the interruption 6, the cover 2 has an opening flap 9 which is materially separate from the reinforcing ribs 5 adjoining on both sides and can be pivoted.

On the upper side, the cover 2 has a circumferential bead 10, which is provided as a hollow profile with support ribs, which is positioned at a distance from the outer edge of the cover 2 and whose overall external dimensions, i.e. over the entire width of the cover 2, is smaller than the clear dimensions of the side walls 4 in the area of the recessed floor 3.

The cover 2 is shown as a detail in FIGS. 10 and 11, the opening tabs 9 protruding here in relation to the inverted edges 8 adjoining on both sides. However, it is also conceivable for the inverted edges 8 and the opening tabs 9 to be aligned.

FIG. 12 shows a section through the lid 2 along the line XII-XII in FIG. 10. The bead 10 with a cut supporting rib in the area of the opening tab 9 can also be seen therein.

FIG. 13 shows four containers 1 according to the invention with a lid 2 combined as a transport unit, and these can be placed on a suitable pallet (not shown).

Due to the rounded shape of the opening tabs 9 formed in the corner area of the cover 2 and the container 1, these are exposed in the common inner area, so that they are protected against being levered out.

In FIG. 14, two containers 1 with lids 2 are stacked to form a column and are shown here in a longitudinal section. According to section XV, FIG. 15 shows the upper container 1 being placed on the lid 2 of the lower container 1, it being clearly evident that the bead 10 is inside the side ten walls 4 rests, so that the upper container 1 is secured against displacement and centered. The height of the bead 10 corresponds approximately to the height of the distance created by the recessed floor 3 to the lower edge of the side walls 4.
