It is known to use a lid on a container to fasten a band-shaped locking device. Such fastening is not particularly effective, since the lid on the cylinder is not sufficiently secure drischer part of the container is attached.

From DE-PS No. 8 88 512 a vessel closure, in particular for canned jars, is known, the vessel having a lid holding section at the top, which is solid and unyielding, and the lid having a circumferential apron which is provided with a circumferential groove section, which engages under the rigid lid holding section. A locking device is inserted in the mentioned groove section. The vessel closure is not particularly suitable for containers with a large mouth and also does not allow easy replacement of the lid with a suitable density as a result - even without using the closure security part, since the groove section of the lid apron cuts off only with difficulty under the lid holder can jam if the lid has been slightly deformed in connection with the first removal.

The invention has for its object a container the above type, which is an easy removal of the attached lid allows, and also a lightweight Replace the lid with a suitable density Follow yourself without using the locking device enables.

The container according to the invention is characterized in that that the lid is made of elastic, thin, unslit Metal plate is made so that the lid holding ab cut down from a revolving, essentially after bottom sweeping, resilient closure surface is delimited, and that the circumferential groove section the cover apron has an elastic contact surface, the groove section in the assembled state of the Lid on the container at least a little below the ver End surface of the lid holding section for resilient contact extends against this surface, and that the lid in one inside the cylindrical part and its sections lying area has a countersunk stiffening part, and that the locking member is strand-like and is set up so that its effective diameter due to a relatively small diameter setting and manipulation by the user to press in or detaching the groove portion of the lid apron against the underside or from the flexible closure surface can be changed away from the lid holding portion. Here  is achieved by the user after the container has been filled with the goods to be packaged, and after the lid is fastened by means of the locking part by slight manipulation of the closure securing the handle of the same in the groove section of the Apron can loosen, with the lid over the lid holder section of the cylindrical part can be pulled up can. After this, the lid can be relatively easily press back onto the lid holding section, there the groove portion under the lid holding portion such engages that a suitable seal between the lid and the cylindrical part is reached. This also applies if the container mouth in relation to the main dimension of the Container, typically the height of the container, is large. The Locking part can if necessary by reattach a separate manipulation by the user. The container is for example in connection with packaging of bulk goods, such as cement, or viscous mate rial applicable.

According to the invention, the lid holding section can be on top an inward bead such as one Have roll or flanging, and the groove portion can on the apron near the lower end the apron can be arranged, and the groove portion can one mainly a semicircle or a c ent speaking cross-section, and the down sweeping, resilient closure surface of the lid holding section can be in an inward beading be provided in the cylindrical part. This will make a the cover is easily replaced since the after common closure surface of the lid holding portion itself a possible connection due to deformation with the first removal of the cover can easily adjust in the groove section of the apron.

Fig. 9 shows the embodiment shown in Fig. 8, wherein the groove portion of the apron abuts the resilient United closure surface of the lid holding portion.

Fig. 1 shows a part of a cylindrical part of a container 1 and associated lid 2 to the container. Above, the cylindrical part 1 of the container has a lid holding section in the form of an externally hollow bead 3 , which in the present case is designed as a roll. But nothing prevents the bead from being created by flanging. The lid holding section 3 has a circumferential downward-facing, elastically flexible closing surface 3 a . The lid has an apron 12 with a groove section 14 , which is optionally arranged in the vicinity of the lower edge of the apron. The lower edge is otherwise provided with a roll 15 . The lid can also have a rounded part 10 in the immediate vicinity of the apron 12 , but this is not absolutely necessary.

In the grooved portion 14 of the apron, a locking portion 18 is provided, which ensures that the lid does not fall off due to an unintended force, such as bumps or blows, in the case of the packaging falling onto a hard surface. The fastener securing part is strand-shaped and set up in such a way that the user can change the effective diameter of the fastener securing part by a relatively small amount by manipulating the setting, so that the clamping effect of the fastener securing part around the apron is either increased or reduced. An increase in the clamping effect of the locking part comes from a reduction in the effective diameter d of the locking part, cf. Fig. 2, ago. An increase in the diameter d causes a reduction in the clamping effect of the locking part. If d has been reduced, pushes the closure securing part 18 of the groove portion 14 inwardly and obliquely upwardly against the closure surface of the lid 3 a holding portion. 3 If the closure safety part has been removed from the apron, the cover can be removed by pulling the apron past the bead 3 . The lid holding section has inherent flexibility.

Fig. 4 shows a locking part in the form of an eight-shaped locking ring 18 a . The large eye of the circlip is indicated by 18 a ' , and the small eye of the eight is indicated by 18 a . If the large eye part 18 a '' of the locking ring 18 a is correctly arranged in the groove portion 14 of the apron, the locking ring can be tightened by the user putting a nail or other thin tool through the small eye part 18 a '' . The nail has a diameter that is slightly larger than the diameter of the eye part, the eye part being widened. The wire in the large eye part 18 then tightens very reliably. Then the small part of the eye is turned a little so that the tightening in the large part of the eye is maintained. The nail is thus a tool by means of which the locking ring can be manipulated.

Fig. 5 shows how the locking ring can be a piece of wire 18 b , the ends 18 b ' and 18 b'' cross each other and extremely small eye parts 18 c' and 18 c '' for gripping a manipulation tool, such as one Nail or a pair of pliers.

Fig. 6 shows a tape-like locking part 18 d , the free ends of the tape overlap each other and are connected to each other by means of a clip 18 e attached to the one tape end. If, for example, the clamp is manipulated using a pair of pliers, the two gripping parts of the pliers being guided away from one another and the one gripping part in the clamp and the second gripping part engaging in the band 18 d , the band 18 d is tightened in the groove section 13 . The effectiveness of the clip 18 is promoted if it is weakly grooved on the inside and the band 18 d is also grooved on the outside.

Finally, Fig. 7 shows how the fastener part can be a multi-wire 18 g , the wires are indicated by 18 g ', 18 g'', 18 g''', 18 g '''' .

The locking parts 18 a and 18 b are both made of metal wire, such as stainless steel wire, and with a wire thickness of preferably 1.25-2.0 mm.

As shown in Fig. 1, 2 and 3, a relatively soft sealing material, such as plastic or dough-soft sealant, can be inserted between the lid holding section 3 and the rounded part 10 of the lid 2 for sealing between the lid and the bead be. The sealant may also be adhesive, so that it is similar to chewing gum.

The groove portion 14 can instead of a locking ring 18 , cf. Fig. 2, have two locking parts arranged one on top of the other, the fastening of the cover to the cylindrical part being further improved.

Regarding the cover holding section 3 of the cylindrical part 1 , it should be noted that this section must have sufficient rigidity to withstand the action of the groove section 14 when the cover is subjected to large unintended forces. As shown, the lid is formed so that it can support the lid holding portion 3 of the cylindrical part when the locking ring 18 tightens in the groove portion 14 . The lid namely has a recessed part 2 b , which is located on a plane a little above the groove section 14 , and which can support the bead 3 from the inside.

Fig. 3 shows an upper support part 6 , which can be guided down over the cover and this can be pressed down via the cover holding section 3 , while the closure securing part 18 is tightened.

Fig. 8 shows a second embodiment of the container 1 with lid 2 , the resilient closure surface 24 a on the lid holding portion 3 at the lower end of the lid holding portion, ie above in a bead 24 , is seen easily. The lid holding portion 3 has an inwardly facing hollow bead 23 which, since the lid 2 has a recessed part 2 b , is supported by the lid recess when the groove portion 14 of the lid apron on the downward closing surface 24 a of the lid holding portion 3 abuts, and when the locking member 28 has been tightened. The United locking member 28 can be out as the locking member 18 described in connection with FIGS . 2-7 forms.

Fig. 8 shows how the bead 24 can have a cross section which is considerably larger than the cross section of the groove portion 14 of the lid apron, wherein the Rillenab section can penetrate into the bead, and wherein the upper part of the groove portion for abutting the resilient Closure surface 24 a can be brought. The mentioned groove section 14 and the mentioned bead 24 preferably have a cross-sectional shape corresponding to a C or a semicircle.

Fig. 9 shows the lid 2 of FIG. 8, which has been pressed down in place, and wherein the locking device 28 has been tightened. During the attachment of the lid can be as described in connection with FIG. 3, to apply a special support member 26, which is guided from top to bottom during the tautening the closure securing member 28 to abut on the cover 2. It can be clearly seen that the groove section 14 of the cover apron with its elastic closure surface presses against the elastically flexible closure surface 24 a of the cover holding section 3 from below, possibly obliquely from below.

The distance a of the groove portion 14 of the lid apron from the upper limit of the lid is preferably at least as large as the height h of the lid portion 3 of the cylindrical part.

As in FIGS. 1, 2 and 3, a sealing compound 11 can be inserted between the cover holding section 3 and the cover 2 in FIGS . 8 and 9. During the attachment of the lid, the mass 11 is pressed down a bit around the lid holding section.

The invention can be varied in many ways without departing from the idea of the invention. Thus, the upper end of the lid holding portion may be a flanged edge which is flat or slightly curved, so that a point of this edge is applicable as a tipping point for the user during the detachment of the locking device 18 and thus during the detachment of the cover 2 . Nothing prevents the above bead from having a cross-section other than that specified, such as rectangular or triangular.

Regarding the lid, it should be noted that it is made from unsupervised slotted plate material. This is especially true Lid apron. Slitting is an expensive ar operation, which is not in the present invention necessary is.
