The invention relates to a grit container made of glass or the like with a removable cover made of metal or other elastically deformable material, which with its retracted inner edge over the outer edge of an edge bead arranged below the container opening can be pressed. In particular The invention relates to a salt and pepper shaker provided with a perforated metal lid.

Such grit containers must have a lid that closes tightly and tightly when in use which does not fall off the latter when the grit container is shaken. On the other hand, it should this cover is mainly used for refilling the grit in the container or for cleaning be easily detachable from the container without special tools.

A spreader lid is already known, the inner edge of which is drawn in with radial incisions all around is provided. These incisions allow the lid edge to spring apart when the ao Lid pressed over the outer edge of the edge bead arranged below the container opening is so that the lid engages elastically resiliently under this bead and in this way without screwing is held on the container. The disadvantage of this design is that the Production of the cover in question is relatively expensive. Machining the radial incisions in the retracted inner edge of the lid is a difficult and time-consuming operation. aside from that the short edge segments between the radial incisions allow only a small radial one Suspension, because the edge of the lid is strongly stiffened by the relatively small radius of curvature. When assembling the spreader, the retracted inner edge must therefore still be a little bit on most lids expanded or retracted further to compensate for the tolerances of the parts to be joined.

The invention is based on the object that occurs due to the slitting of the lid edge To eliminate difficulties, to simplify the production of the grit container and also the Make the lid edge sufficiently resilient without slots.

This object is achieved according to the invention in that one of the two edges (inner edge of the Cover or outer edge of the bead) on the circumference offset points with a smaller radius and between them correspondingly offset points with a larger radius than that around has the same radius of the other edge.

According to one embodiment of the invention, the edge with different radii has an undulating shape Perimeter.

If you press z. B. a lid that has a retracted inner edge with a wave-shaped circumference has, on the grit container with a corresponding bead, then touch the furthest inside places of the drawn-in inner edge first the edge bead of the container body. While the largest bead diameter is exceeded, these areas of the lid are after pressed outside; since the circumference of the edge of the lid is retained, the migrate on furthest outermost parts of the lid edge slightly inwards, and the originally undulating The circumference approaches the circular shape so that the cover can slide over the bead. The deformation of the lid edge takes place in the elastic area of the material, so that the lid edge after skipping the bead circumference back to its original shape with the wave-shaped one The circumference springs back. The inner edge of the lid then holds its farthest on the inside circumferential points firmly place the lid on the bead and thus on the container.

Claims (4)

The grit container 2 tapers from its bottom towards the middle to a constriction 3, then widens again, forms a bead 4, and then tapers conically to its upper edge 5. The bead 4 forms the upper limit of the constricted central part. The constriction has the effect that when the inverted container is shaken, not all of the grit suddenly falls onto the inside of the lid. The consequence of this is easier passage of the spreading material through the holes 6 of the cover 1. The cover 1, the surface of which is slightly curved, has a side wall 7 which is delimited by a drawn-in inner edge 8. This inner edge has the undulating circumferential line 9, which runs in such a way that it touches a smaller circle with the radius a at three points evenly offset on the circumference. Between the locations of the smallest diameter, there are three locations, which are also equally offset on the circumference, at which the wavy line 9 touches a larger circle with the radius b. The bead 4 has the same radius c at all points of its circumference. This radius c is larger than the radius a, but smaller than the radius b of the inner edge 8 of the lid 1. In other words, the diameter of the circumference of the wavy line 9 is greater and the diameter of the inner circle of the same is smaller than the outer diameter of the edge bead 4. The cover 1 has a total height h. The amplitude of the wavy line 9 is denoted by d; it is, for example, about 0.5 mm. When the cover 1 is pressed onto the glass body 2 from above, only the most inner points of the inner edge 8 of the cover touch initially, ie. H. the places with the smaller radius a, the bead 4 of the glass body. When the inner edge 8 of the cover then exceeds the largest outer diameter (radius c) of the edge bead 4, these points are pressed outwards. Since the length of the undulating circumferential line 9 of the inner edge of the lid 8 is retained, the outermost points of the inner edge move at the same time, i. H. the places with the larger radius b, slightly inwards. As a result, the originally undulating circumferential line 9 approaches the circular shape, and the inner edge 8 of the cover can slide over the bead 4. As soon as the inner edge of the lid has skipped the largest diameter of the bead 4, the inner edge springs back elastically to its original shape with the undulating circumferential line 9 and then holds the lid 1 under the bead 4 and thus with its furthest inward points the glass body 2 firmly. The distance between the bead 4 and the upper end edge 5 of the glass body 2 is matched to the height h of the lid 1 in such a way that the end edge 5 strikes the inner surface of the lid 1 when the inside edge 8 of the lid has been pushed over the bead. The deformation of the lid edge must take place in the elastic area of the lid material. According to FIGS. 4 to 6, in a reversal of the configuration according to FIGS. 1 to 3, the outer circumference of the edge bead 4 'of the grit container 2' is designed to be wave-shaped, while the drawn-in inner edge 8 'of the lid 1' is circular. Accordingly, the bead 4 'is shaped so that it touches a larger circle with the radius b at three points evenly offset on the circumference ίο. Between these points of larger diameter then there are correspondingly three points, which are also equally offset on the circumference, at which the undulating circumferential line 9 'of the bead 4' touches a smaller circle with the radius a. The drawn-in inner edge 8 'of the cover 1', on the other hand, has an inner diameter of the same size at all points with the radius c. The radius c is larger than the radius a, but smaller than the radius b ao of the undulating circumferential line 9 / the edge bead 4 '. The circumference of the line 9 'of the edge bead 4' is therefore greater than the inner circumference of the inner lid edge 8 '. If the lid 1 'is placed on the glass body 2', the drawn-in inner edge 8 'of the lid initially slides over the upper end edge 5' of the glass body 2 '. When the lid inner edge 8 'approaches the bead 4', it is pressed outward at those points which are opposite the three points of the undulating circumferential line 9 'with the larger radius b, the lid edge being elastically deformed. After the edge bead is exceeded, the lid edge springs back into its original shape, and its inner edge 8 'comes to rest on the glass body 2' at the three points with the larger radius b of the undulating circumferential line 9 '. As a result, the lid 'is held on the upper part of the glass body 2'. Patent claims: 1. Grit container made of glass or the like. With a removable lid made of metal or other elastically deformable material, which can be pressed with its retracted inner edge over the outer edge of a bead arranged below the container opening, characterized in that one of the two edges is offset on the circumference with a smaller radius (a) and between them correspondingly offset points with a larger radius (b) than the all around the same radius (c) of the other edge. 2. Container according to claim 1, characterized in that the edge with different Radii has an undulating circumference. Considered publications:
