Abstract: The invention relates to a self-opening closure with a pouring spout (12), a self-opening sleeve (20) which is guided in the connector in a helical manner, and a cover (30) which covers the pouring spout (12). A driver cam (24) is formed on the self-opening sleeve, said driver cam defining a guide surface (241). The cover has a driver (34) which defines a front edge (341). The front edge interacts with the guide surface of the driver cam. The front edge and the guide surface are inclined by the same angle of inclination relative to the longitudinal axis in order to allow an optimal force transmission between the cover and the self-opening sleeve. Additionally, the guide surface can be designed in a concave manner, and the front edge of the driver can be rounded in a corresponding manner in order to prevent a radial deflection of the driver towards the inside.

Abstract: The invention relates to a closure for a container for holding a fluid, more particularly an adhesion promoter composition, provided, having a base element which can be fastened in the region of a pour opening of the container and which has an opening through which the fluid can be withdrawn from the container, having a first closure element which in a closed position thereof effects fluid-tight sealing of the opening of the base element and which in an open position thereof releases the opening of the base element, and having a second closure element, which can be fastened to the base element in such a way as to be repeatedly releasable and which, in a container storage mode, secures the first closure element in its storage position and, for a container dispensing mode, releases the first closure element to bring it from its closed position into the open position.

Abstract: What is proposed is a dispensing device for dispensing tablets belonging to a stack of tablets separately. There is arranged, in a casing (100), a conveying element (200) which can be moved to and fro, in relation to said casing, between a dispensing position and a conveying position. The dispensing device also comprises holding means, in particular a lift element (300), which cause the stack of tablets to be kept stationary when a movement of the conveying element, relative to the casing, from the dispensing position into the conveying position occurs, and which cause said stack of tablets to be entrained towards the removing aperture by the conveying element when said conveying element returns to the dispensing position. In this way, the stack of tablets is conveyed in the direction of conveyance by a predetermined amount, particularly by the thickness of a single tablet, when a forward-and-backward movement of the conveying element occurs, and said single tablet can be easily removed.

Abstract: The invention relates to a plastic closing device comprising a pouring part (1) for fixing onto packaging, a screw cap (2) that can be screwed onto the pouring part (1) and a self-opening collar (3) in the pouring part (1) that can be moved downwards with a screw action onto the packaging in order to open the latter. The screw cap (2) has a follower (24), which acts on a stop element (36) of the self-opening collar (3) and which, when the screw cap (2) is first opened, moves the self-opening collar (3) inside the pouring part (1) into a lower position onto the packaging in order to open the latter. When the pouring part (1) is subsequently closed by the screw cap (2), the self-opening collar (3) remains in the lower position. The self-opening collar has several cutting and/or piercing elements (32a, 32b) with a substantially quadrangular basic form. Said form is interrupted by a lower longitudinal edge comprising a sloping and a longer and flatter rising region.
