Definitions
- the one design works with threads as connecting elements between the closure part and the container connection part.
- the other design uses a type of bayonet lock for mechanically connecting the closure part to the container connection part.
- the closure part In both cases, security against unauthorized dismantling is provided by a locking ring which can only be operated with a special tool.
- the closure part In the known security closure of the latter type, in which the closure part is thus mechanically connected to the container connection part via a bayonet closure, the closure part has a radially open, circumferentially extending groove on its contact surface with the container connection part, and two equally wide axially parallel longitudinal grooves, whereby the latter are arranged offset from one another with a circumferential angle of 180 °, that is to say they lie opposite one another on the circumference of the closure part.
- the two axially parallel longitudinal grooves each start from opposite longitudinal edges of the radially open groove running in the circumferential direction and act with two on the inner circumference or on the contact surface of the container connection part, which point towards the container axis or radially inward.
- the cams together which are also offset by 180 ° in the circumferential direction of the container connection part and are arranged offset from one another at different heights parallel to the longitudinal axis of the container connection part.
- the invention is therefore based on the object of proposing a system for security locks previously known, acting in the manner of a bayonet lock, which enables a large number of safe combination pairs, which are absolutely confusion-free with one another, without requiring special or additional production-related expenditure.
- a further duplication of the incompatible combination pairs can be achieved according to the invention by arranging more than two pairs of cams and pairs of grooves on each container connection part and closure part.
- FIG. 1 shows a container provided with a safety closure
- the safety closure 3 or the container connection has a container connection part 4 connected to the cover 2, with which a closure part 5 interacts in order to form the actual safety closure 3.

Abstract
Dans une fermeture de sûreté pour un raccordement de récipient (3), au moins deux cames (9, 10) sont placées sur les surfaces de contact de la pièce de raccordement du récipient (4) et de la pièce de fermeture (5). Ces deux cames coopèrent avec une rainure (7) ouverte radialement qui suit la circonférence, ainsi qu'avec au moins deux rainures (6 et 8) ayant des axes parallèles, sur la contre-pièce respective (4 ou 5), à la manière d'une fermeture à baïonnette. Afin de pouvoir obtenir un système de fermeture de sûreté qui comporte une pluralité de paires de combinaisons sûres ne pouvant absolument pas être mélangées les unes avec les autres, il est suggéré que les paires de combinaisons de plusieurs cames (9 et 10) ainsi que les rainures aux axes parallèles (6 et 8) situées dans le sens circonférentiel de la pièce de raccordement du récipient (4) et de la pièce de fermeture (5), comportent pour plusieurs raccordements de récipients (3) du même type, des écarts circonférentiels (angulaires) (X1) différents.In a safety closure for a container connection (3), at least two cams (9, 10) are placed on the contact surfaces of the container connection part (4) and the closure part (5). These two cams cooperate with a radially open groove (7) which follows the circumference, as well as with at least two grooves (6 and 8) having parallel axes, on the respective counterpart (4 or 5), in the manner bayonet lock. In order to be able to obtain a safety closure system which comprises a plurality of pairs of safe combinations which absolutely cannot be mixed with each other, it is suggested that the pairs of combinations of several cams (9 and 10) as well as the grooves with parallel axes (6 and 8) located in the circumferential direction of the connecting part of the container (4) and of the closing part (5), have for several connections of containers (3) of the same type, circumferential gaps (angular) (X1) different.
