-2- The present invention relates to closures for containers and more particularly to a clamping ring closure whose ring ends are clamped one over the other in the locked position by means of a tension lever closure, the tension lever being secured against unauthorized opening.

In closures of this kind, the application of the tightening force is performed by means of a tension lever pivoted on one end of the tension ring, and by means of a connecting link pivoted on the other end of the tension ring and on the tension lever. To secure the closure, the ring end that is joined directly to the tension lever has a shackle to accommodate a safety lock. The safety lock is threaded through lateral eyes in the tension lever when 15 the tension lever is in the folded-down, locking position.

The securing of the tension lever to assure the o* originality of the packaging as described above provides a degree of strengthening of the closure under severe 0900 handling conditions. However, this strengthening is not considered sufficient, especially when a filled container is dropped. The tension ring ends overlap and one is °o clamped by a securing means, but the other ring end remains unsecured and is able to slip out and open up when 90.

the container is dropped. Thus, the means for security 25 against unintentional opening, the shackle and safety lock, act virtually like a pivot around which the free ring end unwinds. The closure is thus destroyed.

Accordingly, the present invention proposes to 0000 stabilize a clamping ring closure of the above kind in order to ameliorate any such pivoting action.

This is achieved in accordance with the invention by providing the end of the lower end of the ring with a raised locking loop or shackle. When the clamping ring is in the locked position with the ring ends overlapping, the t raised locking loop projects through an opening in the

Z

nF a- t 0 S *0~ a IC 0001 *400I i III--- 3 overlapping ring end and serves to accommodate a safety ring or lock. By this measure the two ring ends can be deformed only together, not just one end alone.

An embodiment of the invention is represented by way of example in the drawing, wherein: Fig. 1 shows a clamping ring in the open position and with the clamping ring closer disposed thereon; and Fig. 2 shows a detail of a portion of the clamping ring of Fig. 1 in the locked position.

Referring to Fig. 1, lower and upper ends i, 2 of the tension ring 11 are placed one over the other so that upper end 2 comes to lie on top of lower end 1. The application of the tensioning force is performed through a tension lever 7 which is pivoted at one end on a first fulcrum bracket 5 mounted on the lower end 1 of the tension ring. The transmission of the closing force takes place by way of a connecting lever 4, which is pivoted firstly to the tension lever 7 and secondly to a second fulcrum bracket 3 mounted on the upper end 2 of the tension ring.

When the lower ring end 1, joined by the tension lever 7, is in the locked position, a safety ring is passed through the lateral eye 10 of the tension lever 7 and through a lateral opening defined by loop 6.

Referring to Fig. 2, close to the end of the lower ring end 1 there is disposed a raised shackle 8 which reaches through a window-like opening 9 in the upper ring end 2.

A second safety ring or lock may be passed through the lateral opening of the raised shackle 8, to rest against the upper surface of ring end 2, thereby providing the necessary additional security.

Claims

4- THE CLAIMS DEFINING THE INVENTION ARE AS FOLLOWS:- i. A clamping ring closure for containers, the ring having upper and lower ends clamped one over the other in a locked position by a tension lever closure means with the closure means including lever members disposed adjacent to ends of the ring and pivotally connected together, and wherein, when the ring ends are overlapping, an upwardly reaching locking loop on the lower ring adjacent the lower ring end is disposed at a location spaced circumferentially from and independent of said tension lever closure means; and a window-like opening on the upper ring adjacent the upper ring end is disposed at Q a location spaced circumferentially from and independent of said tension lever closure means for receiving the o: 15 locking loop therethrough when the ends of the ring are St clamped in locked position, said locking loop being 0 0. o' exposed for reception therein of a locking device when the o ring is in said locked position. 2. A clamping ring closure for containers having open and locked positions including a ring with upper and lower overlapping ends, and a tensioning means mounted on the S ring and disposed near the upper and lower overlapping S ends, said tensioning means comprising a first fulcrum bracket mounted on the ring disposed near the lower end, a 00 016 S 25 second fulcrum bracket mounted on the ring disposed near the upper end, a tensioning lever pivotably mounted at one end on the first fulcrum bracket, and a connecting lever o oQ linking the tensioning lever to the second fulcrum bracket by means of pivotable connections, and wherein: the ring defines a window-like opening disposed near the upper end of the ring and circumferentially spaced from and independent of said tensioning means; and the ring has extending outwardly therefrom a loop disposed near the lower end of the ring r p ,r r t /v~G~ a i b; L 7 CIY~? 5 circumferentially spaced from and independent of said tensioning means and aligned with and extending through the window-like opening when the ring is in the locked position whereby a locking device may be inserted through the outwardly extending loop. 3. A clamping ring closure substantially as hereinbefore described with reference to the accompanying drawings.
