Description

Closure for pot-like utensils is the subject of the invention is a new and advantageous closure for pot-like utensils, such as cans, tubs or the like, preferably for milk cans, with end-rim lid, the shaft of which protrudes into the interior of the pot or the like along its neck.

L) such end rim covers that are in common use z. B. for milk cans and -kül) el used and should spill over the Nl Prevent it while wearing this, however, this is only somewhat guaranteed as long as when the lid shaft is fitted exactly into the neck of the can, which is what makes it easier to open difficult. In the case of the enamel version, the cover cannot be fitted exactly because the enamel ceilings vary in thickness and in the case of the I3rennen also often Kannenhals and the shaft of the lid warp a little and thereby become out of round. That's why it is required to allow a game between the cover shaft and can neck, but what rattling of the lid and leakage of the jug or pot holder when carried brings with it. In order to prevent this, it has already been proposed to use the cover shaft To be made much smaller than the neck of the jug and another one around the lid shaft to put around the springy tinplate edge, which then ensures the tight fit of the lid and the Is to cause sealing.

However, this version is too expensive and does not achieve a perfect one Effect.

The present invention now achieves a solid one in a simple manner Seat of the lid and a perfect seal by placing on the scffiaft of the end rim lid a ring seal made of elastic material is arranged, which when Inserting the lid shaft into the pot or the like]. essentially transversely to the direction of insertion deformed will. In this way it is possible to have a \ relatively large game between Allowing the lid shaft and can neck without the undesirable effects that otherwise occur Having to accept appearances. Manufacturing inaccuracies can be included balance in a simple way.

The closure according to the invention can analogously also be used on a lid use whose shaft overlaps the neck of the jug or pot, in which case the seal is expediently provided on the neck of the pot or the like.

To ensure that the sealing ring is pulled down when the cover is lifted off reliably to avoid, the invention further proposes the seal in a corresponding Insert groove, bead, etc. in the cover shaft, if necessary under pretension.

The elastic ring seal used according to the invention can be any have any profile.

However, it is particularly advantageous to have a seal with an angled To use cross-section, in the unloaded state, the angle opening after at the top and the part protruding at an angle opposes when the cover is put on the part pulled onto the cover shaft.

The closure according to the invention can generally be considered more tight Find cover closure application, z. B. also for potato steamers, food carriers, etc. Like. And analogously, if necessary, also for thermos flasks and the like.

Some exemplary embodiments of the invention are shown in the drawing shown in principle.

Fig. 1 shows a schematic drawing of the lock when it is lifted Lid and FIG. 2 with the lid inserted, FIGS. 3 and 4 show the use an angular sealing ring, Fig. 5 shows the sealing ring according to FIGS. 3 and 4 in the relaxed and FIG. 6 in the extreme pressed state.

The lid I is equipped with the end edge 2 and the shaft 3, which is pushed into the neck 4 of the jug or the pot 5. The shaft 3 of the Lid I has an annular groove 6 into which the elastic sealing ring 7 or 8 is drawn is. When inserting the cover shaft 3 into the neck 4 of the pot 5, how can be seen from Fig. 2, the sealing ring 7 compressed radially and thereby a solid Seat of the cover I and a seal between the cover shaft 3 and neck 4 is achieved.

According to FIG. 3, the leg 9 is of the angular cross section Sealing ring 8 according to the size of the game between shaft 3 and neck 4 more or less pressed against the part pulled onto the cover shaft 3.

According to Fig. 4, the shaft 3 of the lid I is with one to the End edge 2 subsequent paragraph 10 equipped, to which the annular groove 6 is connected. This design provides a better hold of the lid I in the neck 4 of the jug or the pot 5 is reached. because wedging of the seal promoted when pulling out will. In this embodiment of the cover shaft 3, the cover 1 is inserted easier to perform than pulling out. With g 'and g "are the extreme positions of the leg 9 of the seal 8 shown in the loaded and unloaded state.

PAT £ NTANsPnLcHE: 1. Closure for pot-like utensils, such as jugs, tubs or the like, preferably for milk jugs, with a closing rim lid, of which Shank into the interior of the pot or the like, along and parallel to the neck of the same, protrudes, characterized in that on the shaft (3) of the end edge cover (i) a ring seal (7 or 8) made of elastic material is arranged is that when the cover shaft (3) is pushed into the pot (5) or the like. Essentially is elastically deformed transversely to the direction of insertion without affecting its perpendicular To change the situation in essentials.
