Stackable jar that can be closed with a snap-on lid.

The invention relates to a stackable one with a slip lid lockable box according to the general term of the protection claim

If the lids are still missing, these cans can be nested in this way be stacked so that one can protrudes up to the support provided inside the next can such stacking can occur when the empty Storage height can be saved for cans, for optimal utilization The height of the supports is designed so that the boxes can be nested as far as possible The limit for sticking together is reached when the outer footprint of a can to the inner surfaces of the side walls of the Dos., 'below. Are the stops inside the can in terms of height so that the aforementioned State is reached, arises in that of the inserted second can in the first can not filled lower space an airtight space on all sides. When destacking Such cans can cause a suction effect that makes unstacking difficult

Such a suction effect is avoided by the fact that in Openings provided in the bottom of the can.

In Fälienjin where those were closed with a slip lid When closed, cans require an open connection between the contents of the can and the atmosphere, those in the bottom of the can are used provided openings at the same time for this purpose, a prerequisite for the last-mentioned function is of course that knobs or similar local elevations are provided below the bottom, so that the openings in the bottom of the can not closed by placing the can on a level floor will.

Such openings in the generic stacking cans have the disadvantage that these cans are only used for such purposes are suitable in which openings in the bottom are acceptable.

Proceeding from this, the object of the invention is to pass through the base openings in the generic stacking boxes to replace other, functionally equivalent measures that are less disruptive to the intended use of the can.

This object is achieved in relation to unhindered unhindered by suction by a design of the can according to the features of the characterizing part of claim 1.

In order to be able to keep the contents of the can in contact with the atmosphere even when the lid is on, the can and the slip lid according to the characterizing feature of claim 2 connected to each other.

In this way, the two required functions can be used without any disruptive influences on the usability of the Realize can in a surprisingly simple way.

An exemplary embodiment is shown in the drawing. Show it:

Fig. I shows a longitudinal section through the can attached slip lid,

Fig. 2 is a section through the can along line H-II

The stackable can 1 has a flat base 2 and looks evenly obliquely downward on the outer surface of an aicih downwardly tapering truncated cone with a square base extending side walls 3. In the inner edges of the Side walls 3 support ribs 4 are provided. When stacked one inside the other of the cans 1, these can be plugged into one another with their base 2 except for the support ribs 4.

The radii of curvature R1 and R2 of the vertical outer edges and inner edges of the side surfaces 3 of the can 1 are each over the entire height constant. However, they differ from each other in that the outer radius of curvature Rl is greater than that inner radius of curvature R2 is when the cans are stacked one inside the other As a result, a vertically extending air gap remains at the edges, which is for the necessary air compensation when destacking.

The box 1 is covered with a slip lid 5.1m area The inner edges of the hooded lid 5 are provided with angular ribs 6 that cut at right angles. in the lid eight such angular ribs 6 formed, namely two on each long side, each near the vertical one Edges of the slip lid. The angular shape of the angular ribs 6 ensures that even when the nozzle 1 is placed Snap-on lid allows air to be equalized through the spaces between the angular ribs 6, between the inside of the can and the atmosphere The vertical legs of the angular ribs 6 serve further-
