Definitions
- the invention relates to a closure for cans provided with an edge bead of different diameters, in the lid of which there is a tear-open tab for forming a pouring opening, consisting of a plate-shaped base body made of plastic and spanning the lid, which is arranged with a stationary and with at least one oppositely arranged resilient end edge web engages under the edge bead in a snap-lock manner, the resilient end edge web being radially displaceable in a sliding guide of the base body and wherein an annular seal encompassing the pouring opening of the cover can be clamped between the base body and the cover.
- Closures of this type are known from DE-OS 34 25920.
- a compression spring is clamped between the slide and an edge area of the base body, which has the task of pressing the slide element against the edge of the can.
- the slider has two resilient legs, at the end facing the can a nose is provided which engages under the rim of the can. In order to be able to release the closure from the can, the resilient legs must be pressed inwards against each other so that the lugs can detach from the rim of the can.
- Such an arrangement is technically complicated, complex in terms of assembly and costly, quite apart from the fact that the slider in the base body can only be insufficiently guided and the compression spring for the deposit is particularly susceptible to dirt and the like.
- the invention is therefore based on the object, the aforementioned known closure in terms of
- the resilient front edge web is designed as a self-resilient spring element having a loop-shaped bulge, one loop web of which is supported on the base body and the other loop web in a handling element with the one located thereon resilient front edge bridge merges.
- the advantage of this arrangement is that the spring element can be formed in one piece, due to the loop-shaped bulge generates a sufficiently large spring force, is therefore inexpensive to manufacture and particularly easy to assemble. As a result of this configuration of the spring element, better guidance can also be achieved on the underside of the base body.
- the claim 2 shows that the spring element consists essentially of a rectangular cross section.
- the special design of the handling element is listed. This handling element is of particular importance with regard to the placement of the closure on different diameters and with regard to the release of the closure from the can. If the handling element is designed as a wedge-like thickening, it forms an inclined sliding surface, which when Placing the closure on the edge of a can causes the spring element to be moved against the spring force and to snap into place. On the other hand, this wedge-like thickening of the handling element gives the possibility of withdrawing the spring element when one wants to detach the closure from the can, because the wedge-like thickening forms a welcome contact surface for the finger.
- the embodiment according to claim 4 is recommended, according to which the loop-shaped bulge extends perpendicular to the plane of the plate-shaped base body. This means that the bulge comes to lie below the base body. It therefore does not hinder handling the can.
- the design of the closure according to claim 5 has the advantage that the spring element can be inserted in the radial direction from the end face into the sliding guide of the base body.
- the sliding surface is much larger than in the prior art, so that the spring element is sufficiently guided in each spring position. It therefore only requires the assembly effort to snap the loop web facing away from the resilient front edge web into a recess in the base body, which of course presupposes a certain deformation of the spring element.
- This engagement of the spring element can be carried out manually without tools, whereas the removal of the spring element from the locked position is expediently carried out with tool aid, which essentially consists in compressing the loop-shaped bulge.
- the clamped spring element is absolutely safe and cannot lead to injuries. His shift to that The resilient front edge web can be released in a particularly simple manner by either pressing in the loop-shaped bulge with the finger or moving the spring element on the wedge-like thickening.
- the spring element according to the invention itself has the resilient front edge web, without this having to be actuated in particular.
- the front edge web does not have to be resilient in itself, but rather has a resilient effect due to the resilient design of the spring element.
- this resilient front edge web has a concave curvature, which is part of the spring element.
- the spring element is made of an elastic and resilient plastic having properties.
- plastic especially colored or uncolored polyoxymethylene has proven to be advantageous.
- FIG. 1 a side view of a can with a closure placed thereon, shown in section,
- FIG. 2 a bottom view of the closure according to arrow A in FIG. 1
- FIG. 3 a front view of the closure according to arrow B in FIG. 1
- Figure 4 is a side view of the spring element according to the invention.
- FIG. 5 a top view of the spring element according to FIG. 4.
- a can (1) is shown in a side view, which has a peripheral edge bead (2) and a lid (3) on the opening side.
- a pouring opening (4) which is formed by a pull tab, not shown.
- a closure is shown in section, which must be suitable for effectively closing cans of different diameters when the tear-open tab is released and the pouring opening (4) is open.
- the closure (26) has a plate-shaped base body (5), in particular made of plastic, which engages over the can.
- This base body (5) has on one side a stationary front edge web (6) and on the other side a resilient front edge web (7) which engages under the edge bead (2) of the box (1).
- annular seal (8) between the base body (5) and the can lid (3), which is pressed against the lid (3) when the base body (5) is placed on the can and the pouring opening ( 4) grips the can.
- This ring seal (8) is supported on the inside by an insertable cap (9) which has a passage opening (10) congruent with the pouring opening (4).
- the closure (26) can have a pouring spout, but this is not absolutely necessary.
- the pouring spout (11) is provided with a closure cap (12) which can be placed on a thread. If you want to do without this pouring spout (11), that's the one Base body (5) designed continuously plate-shaped.
- the resilient front edge web (7) is part of a spring element (14) which is displaceable in a radial sliding guide (13) on the underside of the plate-shaped base body (5).
- the spring element (14) has a loop-shaped bulge (15) through which the two
- Loop webs (16, 17) are formed.
- the loop web (16) is intended to engage with an edge (19) in a recess (20) of the plate-shaped base body (5) and thus to generate the supporting force for the spring action of the spring element (14).
- Loop web (17) has a handling element (18) and the front edge web (7) located thereon.
- This front edge web (7) is not resilient in itself. Rather, its spring action results from the spring property of the spring element (14).
- the handling element (18) has a wedge-shaped thickening, which has a double function.
- the flank (27) is used to make a spring element (14) push back when the closure (26) is placed on a can (1), because the edge bead (2) strikes this flank (27).
- the flank (27) or the loop-shaped bulge (15) serves to manually push the spring element (14) back against the spring force and to remove the closure (26) from the can ( 1) to solve.
- the sliding guide (13) is formed by two legs (21, 22) which have an undercut groove (24) (cf. FIG. 3) into which guide strips (23) of the spring element (14) engage.
- These undercut grooves (24) are open radially outwards, so that the spring element (14) with its guide strips (23) can easily be inserted radially from the outside into the slide guide (13). All that is then required is the measure of pushing the loop web (16) (see FIG. 1) inwards and latching it into the recess (20).
- the loop web (16) therefore has a greater length than the loop web (17) so that the edge (19) of the loop web (16) can be securely anchored to the plate-shaped base body (5).
- the undercut grooves (24) are formed by angled legs (21, 24) which are arranged on the underside of the plate-shaped base body (5). There is a sufficiently large space between these legs (21, 22) to allow the loop-shaped bulge (15) of the spring element (14) to pass through.
