DE2104193B2 - LID CLOSURE FOR CONTAINER WITH RELATIVELY LARGE OPENING - Google Patents

Description

slight manipulation of the lid when putting on lllem, however, when losing weight, is hindered because the Clamping ability diminishes after prolonged use and the secure seal, especially in case of drop loads then not my given im.

Finally, a closure for cans is known in which the can body is formed vertically out of the can body Flange sections and cover flanges are distributed over the opening circumference and in which a tension wire is inserted as a locking part between the flange sections and the ι LidelfJufische (DT-AS 10 48 533). the The entire sealing effect results solely from the clamping force of the tension wire. those of this between the flange portions of the can body and the lid flanges. ι

This simple clamping lock is sufficient for cans with a relatively small content and lower weight. As a closure of a keg with a large opening and of great weight of the contents ^: it cannot be used, however, because in particular the tensile stresses on the lid and the deformation forces, especially when falling and edging, cannot be safely absorbed.

The invention is therefore based on the object to create a particularly economical lid closure for the aforementioned type of container, in which the disadvantages described above are avoided, which on the one hand withstands high fall loads and on the other hand, it is particularly easy to manipulate. So easy closing and opening of the container, as well as a sufficient seal security is achieved.

This object has been achieved according to the invention in that in the lying between the contact surfaces Container edge sections each one on the outside of the container open and the shape of the lid edge segments adapted recess is arranged, the one on the side facing the sealing ring that extends from the outer edge in an arc-shaped and inclined downward direction, Has known Zugflächenc and the lid edge segments on their facing the container edge Side are provided with adapted inclined surfaces, which when the lid is on the pulling surfaces of the container indentations.

This eliminates all of the above-described deficiencies in the known lid closures. With the invention a lid closure is created with almost seamlessly interlocking fastening elements been obtained in a simple manner by molding in or out of the container and cover wall and no procedural requirements going beyond the usual shape of the containers and lids and make necessary equipment expenditure. The lid closure according to the invention meets all requirements to the conditions mentioned at the beginning with regard to fall and transport safety, tightness, Economical and easy to manipulate. Through the training and arrangement of the in the container wells containing, in the shape adapted lid edge Scgmente as well as the folded over The clamping ring protruding horizontally from the locking cam is summarized as a multiple locking and thus optimal closure safety is given for wide-necked containers made of plastic. As a result the inventive design of the lid edge segments and the matching container wells When the lid is on, there is a completely smooth surface for the tensioning strap around the circumference of the container

In FIGS. 1 and 2 there is a container 10 with a large opening that corresponds almost to the container diameter and a matching opening in FIG. 1 attached cover 11 is shown. The container and also the lid are made of a plastic. Wiu from Fig 2, the container 10 has on the outside at its edge a hcrausgeformten from the Behällerwandung annular bead 12 with several, in radial direction over its outer diameter protruding locking cams 13, which are formed out of the annular bead and with the same space on the circumference of the annular bead are evenly distributed On the upper rope facing the edge of the container, the surfaces of the locking cams run over in an arc shape into the edge surface of the ring bulge. while on the lower side facing the container bottom, the cams are each flattened at the same height. In the outer container edge sections, which lie between the locking cams 13, the container wall has an arcuate recess immediately below the annular bead 12

The lid It has shown in its in the drawings Position a downward angled edge, which by symmetrically made cutouts 15 in several segments of the same length, each arranged with the same space over the entire circumference 16 is split. The edge of the container, the segments 16 are adapted so that they are when the Lid on the container outside around the lying between the locking cams 13 portions 12; i des Grasp the annular bead 12 and, when pressed against the edge of the container, engage in the arcuate recesses' 4. The outside vertical surfaces of the Dek kelrand segments are at the same height mil the adjacent outer surfaces 10, -i of the container located below the locking cams 13 ters. A band-shaped clamping ring 17 wrapped around the outside of the Deckelrard segments 16 holds the Seg ments in this tense position and lies sclbs with its upper edge directly below the Verrie gelungsnocken 13. The clamping ring is on the lid edge segments by projections 18 and 19 unclearable held, the above and below the clamping ring from the outer .Segment surfaces heraiisra gene and include the clamping ring at its edges.

The cutouts 15 in the cover are so beniessei that with the lid placed on the container 11 di Locking cams 13 protruding from the annular bead 12 of the container freely pass over the clamping ring 17 the cutouts protrude. As already mentioned, di

Claim: Lid closure with inserted, elastic sealing ring for containers with a relatively large opening, in particular for barrels, jugs or the like made of plastic, the container on the outside at its edge an annular bead formed out of the container wall and protruding radially Has locking cams, while the cover is angled downward in the Fastening position has the ring bead on the outside, which is surrounded by vertical cutouts in several, at least partially with projections protruding outward from the lower end section provided segments is divided, which when the lid is attached below the annular bead with a clamping ring placed around the segments on the outside can be clamped against the container edge and are lockable below the locking cams, the container at least at its edge three formed out of the annular bead towards the outside of the container, symmetrical on the circumference arranged locking cams with their side facing the clamping ring right-angled clamping ring contact surfaces and starting from these, has contact surfaces for the clamping ring that run perpendicularly in relation to the container plane, characterized in that in each of the container edge sections (12 »·) lying between the contact surfaces (10a) one on the Container outside open and the shape of the lid edge segments (16) adapted recess (14) is arranged. the one on the sealing ring (21) facing side an arcuate and sloping downward from the outer edge, known per se Has pulling surface (22) and the lid edge segments (16) on their edge facing the container Side with adapted inclined surfaces (23) are provided, which when the cover is attached to the The pulling surfaces of the container indentations rest on. The invention relates to a lid closure with an inserted, elastic sealing ring for containers with relative large opening, especially for barrels, jugs or the like made of plastic, the container on the outside at its edge an annular bead formed out of the container wall and protruding radially Has locking cams, while the cover is angled downwards in the fastening position has the rim surrounding the annular bead on the outside, which is divided into several, segments provided with at least partially outwardly projecting projections from the lower end portion is divided, which when the cover is in place below the annular bead with an outer ring around the segments The clamping ring that has been placed can be clamped against the container edge and locked below the locking cams (> o Are lockable, with the container at its edge at least three from the annular bead to the outside of the container molded, symmetrically arranged on the circumference locking cams with on their The side facing the clamping ring has right-angled clamping ring contact surfaces and abutment surfaces proceeding from these and running perpendicularly with respect to the level of the container for the clamping ring. In a lid closure for containers with a large opening, so for so-called wide-necked containers, one is Considerable drop resistance is required, as the stresses that occur in the event of a fall are due to deformation of the container especially in its lid part and the sudden overpressure in its interior lightly press the lid lock and cause consequential damage. This is especially true if the container and lid are made of plastic. In general, lid closures for containers of the type described are already known. So have for example Known plastic barrels on the outside of their edge an annular bead and the lid one by vertical incisions Outer edge subdivided into segments, the outer edge of the annular bead in the fastening position of the lid includes. Outside around the edge of the lid there is a protrusion placed in its position secured clamping ring, with which the lid edge segments below the ringwuisies can be braced against the edge of the lid. These known cover closures, however, offer fall loads no sufficient guarantee for a tight fit of the lid, since a deformation of the Often the lid edge, starting from the deformed point, over the barrel in the area of the lid closure the ring bulge of the barrel can slip away. It is also known. Barrels at their opening board Surrounded on the outside with a prefabricated reinforcement ring, which is radial on the upper edge has outwardly protruding abutment segments for the clamping ring (DT-Gbm 69 39 508). The outside The edge of the lid has corresponding recesses and also protruding outwards on its lower edge Segments. After placing the lid on the barrel mouth, the segments are in a predetermined position Distance and offset from one another in such a way that the clamping ring can be inserted between them and through scm Bracing the lid is set. The sides of the segments facing the tightening strap have sloping surfaces that rise or fall chen to put the lid in a firm and tight position on the barrel mouth when tightening the clamping ring to pull. This known lid closure has the disadvantages. that the reinforcement ring before the formation of the barrel inserted into the production mold and good for achieving drop resistance with the edge of the barrel must be welded, which is technically cumbersome and time consuming and to achieve a economically justifiable production speed requires extensive and expensive production facilities. In addition, the ring parts must be prefabricated as molded parts, which also cause considerable costs. This known embodiment has the further disadvantage that both the cover-Verspan nen the gasket tensile load as aucl. that last de transport load on sections of the clamping ring and the locking abutment segments must be taken, so that these two elements do not achieve the desired cost savings Way can easily be made of a plastic. Furthermore, a lid closure is known in which the lid ver on its inside on the circumference divided, barb-like cams or a corresponding cam ledge, which at up set cover under the inside container or Grab the edge of the barrel (DT-Gbm 69 26 91b). This proposal has also proven to be disadvantageous because di
