Description

Closure with a sealing ring that is enclosed on all sides and expanded on all sides when the hook lever or the like is tightened. Closures are already known in which a rubber ring enclosed on all sides is pressed apart in all directions during closure by a projection of a movable closure part and thus seals on all sides. They are pushed apart by screw caps, hook levers or the like.

According to the invention, the novelty consists in the fact that the separation e of the rubber ring by a sliding one that is already common with EZpansionsstopfen Ring is made, the hook has, which in the usual way over a bead of the lid to grab. This training enables the closure to be attached to all common ones Vessels using the usual lid, without, as before, a special one Processing of the vascular opening is necessary.

The drawing shows in fig.r a section through a container with a closed, sealed lid, fig.a a section through one side of the lid, 1 @ clamping part released, fig.3 a section as before, but with a differently shaped sealing ring, fig. 4 : the hook between the clamping part and the cover. Mer the usual bead a of the container b engages a lid d, on the lower, outer edge of which there is also a bead l. Between the side walls of the container b and the lid d , an expandable sealing ring g, of rectangular, round or the cross-section described in more detail below, is attached, which comes to rest with its upper edge against the bead a of the container. Against the other edge of the ring presses from below a clamping part h (compression ring) running loosely around the container, which - is connected to the lid by several conventional hooks reaching over the bead L of the lid d, whereby the now between the parallel walls of the container and the expandable ring g located on the cover is axially compressed in the known stuffing box effect, expands radially, is pressed against the walls and thus creates a perfect seal.

The sealing ring has one each on its upper and lower edge Groove-shaped recess f. in each of which a circumferential elevation c on the container bead and e engages the clamping part, namely; `as shown in Fig. 2 in the non-tightened state can be seen, wedge-like.

Such seal designs are already common practice.

When any internal pressure in the container increases, it pulls during the lifting of the cover d by transmission to the lower movable clamping part k by means of the hook 1a of the sealing ring g automatically tighter and thus increases the Seal.

The hook levers h, either loosely or firmly from the small part h or from the cover d , which in the latter case then extend over a bead similar to the cover bead l on the loose clamping part, grip in the usual way with a lug generally over a bead elevation m in a snap action, after the clamping part has previously compressed the sealing ring when tightening. After overcoming the bead elevation in, the clamping part is pushed back by the automatic expansion of the sealing ring, whereby the cover is held in place.
